abstract = {Muscle health, encompassing muscle mass, composition, strength, physical performance and patient-reported outcomes, is a key determinant of clinical outcomes across the life course and a wide range of disease states. Despite growing recognition of its importance, muscle health remains insufficiently integrated into routine clinical nutrition practice, and nutritional recommendations often rely on population averages rather than individual muscle status, disease phase or metabolic context. This narrative review, developed by an international multidisciplinary expert group, synthesises current evidence on muscle health and clinical nutrition across major clinical domains, including ageing, cancer, metabolic disease, obesity, weight loss interventions and acute illness. We critically appraise methods for assessing muscle mass, function, and patient-reported outcomes, highlighting their strengths, limitations, and feasibility for clinical practice and research. In doing so, we highlight marked heterogeneity in metabolic and functional responses to nutrition and exercise interventions, underscoring the need for phenotyping, endotyping and precision nutrition to individualise protein and energy requirements. Beyond biological mechanisms, we address key implementation challenges limiting translation into practice, including inequities in access to dietetic and other rehabilitation services, variability in health system organisation and underuse of functional and patient-centred outcomes in trials and routine care. Finally, we propose a translational research agenda to harmonise outcome measures, improve trial design and support integration of muscle health assessment and personalised nutritional strategies into clinical care pathways. By positioning muscle health as a central and actionable outcome of clinical nutrition, this review supports a shift from uniform recommendations towards more personalised and effective nutrition care.},

abstract = {INTRODUCTION: The LIFE-ID (lifestyle interventions for adults with intellectual disabilities) intervention, a multicomponent and multilevel lifestyle programme, was developed to improve the lifestyle of adults with ID and the support provided by their interpersonal and organisational environment. This paper describes the protocol of a multiple baseline one-arm feasibility and effectiveness study of the LIFE-ID intervention. METHOD AND ANALYSIS: To evaluate the effectiveness of the LIFE-ID intervention for adults with ID, alongside an embedded assessment of feasibility, we employ a one-arm multiple-baseline trial in the Netherlands, in collaboration with healthcare organisations providing support to adults with ID. The LIFE-ID intervention intervenes at intrapersonal, interpersonal and organisational levels and uses a tailored approach to improve both physical activity and dietary quality in adults with ID. To support healthcare professionals in selecting interventions, the lifestyle support tool was developed, including existing, effective, and ID-specific nutrition and physical activity interventions. The lifestyle support tool takes into account intrapersonal, interpersonal and organisational characteristics and considers the participants' wishes and needs related to their personal lifestyle goals. An embedded feasibility evaluation of the LIFE-ID intervention is conducted with the first 15 participants in the study and their involved healthcare professionals. Information on dose delivered, dose received, acceptability and fidelity of the intervention performance compared with the description is retrieved through biweekly reflection forms obtained from direct support professionals. Group interviews are conducted to collect feedback on the experiences with the LIFE-ID intervention discussing the following topics: acceptance and suitability of the intervention, and barriers and facilitators during execution. Outcomes related to the lifestyle support tool include usability, usefulness and ease of use. To evaluate the effectiveness of the 6-month LIFE-ID intervention, 80 adults (≥18 years) with ID are included (including 15 participants from the feasibility evaluation). The primary outcome is physical activity. Secondary outcomes on the intrapersonal level include dietary quality, physical fitness, body composition, calf circumference, blood pressure, heart rate, frailty, anxiety, depression, behavioural problems and goal attainment. On the interpersonal level, outcomes include attitude of professionals towards support in healthy exercise and nutrition. On the organisational level, outcomes are barriers and facilitators associated with creating a healthy living environment, and determinants that affect the implementation of the LIFE-ID intervention. ETHICS AND DISSEMINATION: The study protocol is approved by the Medical Ethics Review Board of the University Medical Center Groningen (METc 2023-520). Written consent is obtained from all participants who are capable to provide consent, and from legal representatives when they are not. Study findings will be disseminated through peer-reviewed publications, conference presentations and accessible summaries for participants, families and healthcare organisations. TRIAL REGISTRATION NUMBER: The study has been registered in the Overview of Medical Research in the Netherlands (OMON; NL85438), which is linked to the International Clinical Trial Registry Platform (ICTRP).},

abstract = {BACKGROUND: Current recommendations encourage consuming sufficient intake of high-quality protein, with ≥60% derived from plant-based sources, to support both nutritional requirements and sustainability goals. OBJECTIVES: This observational study assessed protein intake, quality, and sources in predominantly plant-based meals and diets using a national survey, offering insights to support a more sustainable and nutritionally adequate dietary transition. METHODS: In the Dutch National Food Consumption Survey (2019-2021), protein intake was assessed using 24-h recalls in adults aged 18 to 79 y. Total, plant-based, and animal-based protein intake were analyzed per meal and per day. Protein quality per meal was evaluated using the Meal Protein Quality Score (MPQS). The association between protein quantity and the proportion of plant-based protein was evaluated based on how often meals reached adequate protein quality (MPQS >100). Furthermore, protein sources across food groups in diets with ≥60% and <60% plant-based protein were compared. RESULTS: Among 1747 adults [57 (44-68) y, 50% male], the median protein intake was 0.93 (0.75-1.13) g/kg/d. Only 8% ( = 147) had a diet comprising ≥60% plant-based protein, with a median intake of 0.83 (0.63-1.05) g/kg/d. As the proportion of plant-based protein increased, both protein quantity and quality decreased. When protein quality was low, lysine was the most common limiting amino acid. Only 3% of all meals achieved ≥20 g protein, ≥60% plant-based protein, and optimal protein quality, with dairy as key protein source at breakfast and lunch, meat alternatives at dinner, and grains at all meals. CONCLUSIONS: This study shows that only a small proportion of Dutch adults met both protein-related recommendations and sustainability goals, due to lower protein quantity and quality in more plant-based diets. This study emphasizes the need for professional guidance, especially in individuals with higher protein requirements, to facilitate a successful transition to a more plant-based diet.},

abstract = {The global syndemic of obesity, undernutrition and climate change - three interconnected challenges - threatens both human and planetary health. This review focuses on one critical intersection: older populations living with overweight and obesity in the context of sustainable nutrition. Obesity and sarcopenia, particularly the co-occurrence called sarcopenic obesity, are often overlooked until the onset or exacerbation of other diseases necessitates secondary care. Preventing sarcopenic obesity requires reducing excess fat mass while preserving muscle mass and function. This involves lowering total energy intake while ensuring adequate protein intake in terms of quantity, quality and distribution, combined with physical activity, particularly resistance exercise. Short-term studies show that both the source and dose of dietary protein significantly influence muscle protein synthesis rates. Longer-term studies examining the impact of plant-based diets on muscle health in older adults with or without overweight or obesity remain limited. Animal protein have shown a modest advantage over most plant-based protein in supporting muscle mass. Qualitative studies suggest that emphasising both the health benefits and palatability of plant-based protein sources is key to promoting dietary changes in older adults. In older adults with obesity, it is challenging to combine energy restriction with higher protein intake, especially when protein sources are plant-based. To prevent and treat sarcopenic obesity in older adults and support planetary health, a shift toward more plant-based protein sources is required, while ensuring sufficient protein quantity and quality to preserve muscle health during weight loss.},

abstract = {BACKGROUND: The adoption of mobile health (mHealth) technologies among older adults remains significantly lower than in younger populations, despite their potential to promote healthier lifestyles and mitigate age-related health risks. OBJECTIVE: This study aims to explore the perspectives of retirement-age adults on mHealth interventions, identifying factors that influence their adoption, such as persuasive elements in the app design and psychological techniques. METHODS: A qualitative focus group study was conducted with 19 Spanish participants recruited from urban community settings in Madrid, Spain (mean age 61.5 years; 15/19, 79% women). Participants discussed their attitudes, barriers, and preferences for mHealth tools. Focus groups were recorded, transcribed, and coded using an iterative process to ensure rigorous data analysis. An abductive approach was followed, using the persuasive design principles framework and the behavior change techniques' taxonomy, and representing any theme outside those frameworks. RESULTS: Participants expressed generally positive attitudes toward mHealth tools, favoring intuitive, user-friendly designs that are minimally time-demanding. However, significant barriers also emerged, such as low digital literacy and concerns about technology dependence. Key design preferences (persuasive design principles) and psychological techniques (behavior change techniques) were deemed beneficial, with preferred features such as tailored and meaningful goal-setting, self-monitoring, positive feedback (eg, congratulating messages after achieving a goal; social rewards), and a moderated use of notifications and prompts. Participants also stressed the importance of age-appropriate recommendations (eg, suggested diets for their age and characteristics) and design (eg, accessible, easy-to-use interfaces and human-like communication). Additionally, some preferences appeared to be culturally grounded (eg, rejection of anglicisms and the desire for locally relevant content, such as suggested activities specific to Madrid). Social support mechanisms, such as group activities and peer interactions through mHealth, were seen as critical for fostering motivation and engagement. CONCLUSIONS: mHealth interventions for this population should offer accessible and easy-to-use interfaces along with initial tutorials, facilitating an easy onboarding to overcome low digital literacy, thereby enhancing both usability and initial adoption. Furthermore, by providing meaningful, tailored content (eg, personalized diets and goals) and social features that foster peer connection (eg, user chats or organized activities), these tools may better support sustained engagement over time.},

abstract = {BACKGROUND: Obesity is defined as a chronic, relapsing disease, characterised by its persistence and the frequent recurrence of weight gain following weight loss. It is linked to chronic diseases and reduced quality of life. Sustainable weight loss requires long-term dietary and behavioural changes. Dietetic treatment outcomes vary per patient, leading to differing success rates and effectiveness. Although understanding patient experiences is crucial for designing effective, patient-centered strategies, little is known about their lived experiences. This study aimed to obtain a better understanding of the perspectives and experiences of patients with obesity receiving dietetic treatment in primary health care in the Netherlands. METHODS: This qualitative interpretive study included 26 patients with obesity who were consulting or had consulted a dietitian. We performed purposeful sampling to ensure a sample diverse in socio-cultural background, region, age and health literacy. Semi-structured interviews were conducted using a predefined topic guide, with room for flexibility to explore emerging topics. We analysed the interview data using reflexive thematic analysis as described by Braun and Clarke. RESULTS: Four interconnected themes were constructed from what patients named to be important in dietetic treatment: (1) personalised treatment as a foundation for success, including feeling heard and receiving responsive and adaptive treatment (2) the personal impact of the dietitian on treatment, through the dietitian's attitude, professionalism, and background; (3) a personalised and holistic approach for lasting change, including clarity about the dietitian's ways of working, motivational and emotional support, attention to life context and guidance in developing sustainable habits; and (4) tailored and accessible advice, focusing on practical tools, understandable information, and consistency of advice. CONCLUSION: This study highlights that successful dietetic treatment for adults with obesity depends on personalised support, a strong patient-dietitian relationship, and holistic attention to psychological and behavioural factors. Clear communication, involvement from the start, and practical, tailored advice help patients comply with treatment and apply recommendations in daily life. Findings emphasise the importance of aligning dietetic treatment with individual patient needs and expectations.},

abstract = {An increased protein intake is required during aging to preserve muscle mass. A predominantly plant-based diet is beneficial for the climate and may lower the risk of certain non-communicable diseases, but could also lead to protein below recommendations. This study seeks to elucidate facilitators and barriers in adults aged 55+ adopting a diet that is both predominantly plant-based and provides sufficient protein to preserve muscle mass. Three focus groups were conducted with 30 Dutch adults, aged 55-74 years. The focus groups explored participants' views on protein-rich, (predominantly) plant-based diets. Participants discussed a range of topics, including perceptions of protein needs, attitudes toward plant-based foods, social influences, and practical considerations such as taste, cost, and habits. Three researchers independently thematically analysed the data and facilitators and barriers were mapped to the Capability (C), Opportunity (O), Motivation (M) - Behaviour (B) model. Health effects (M) and taste (M) were both the most dominant facilitators and barriers regarding transition towards a more plant-based, protein-rich diet. Knowledge (C) and social influences (O) were important factors that influence dietary choices regarding the other COM-B model components. Environmental benefits (M) and animal welfare (M) were mentioned as additional benefits rather than as main facilitator. Participants expressed a clear need for enhanced knowledge and tools about the health and environmental benefits of plant-based, protein-rich diets. Improving taste and highlighting health benefits are key to fostering positive attitudes and encouraging the adoption of protein-rich, plant-based diets among adults aged 55+.},

abstract = {BACKGROUND: Progressive Resistance Training (PRT) and adequate dietary protein are crucial for preventing and managing sarcopenia and frailty in older adults. To date, the optimal intensity of PRT and the added value of dietary protein for enhancing muscle mass, strength, and physical performance in frail older adults remain unclear. This randomised controlled trial aims to determine the efficacy of various PRT intensities and adequate dietary protein intake in improving muscle mass, strength and physical performance in frail, community-dwelling older adults. METHODS: This study is a two-step randomised clinical trial involving 300 frail older adults. Participants will engage in a 12-week PRT twice weekly. Initially, participants will be randomised to specific training intensities, ranging from 20 to 80% of their one-repetition maximum (1-RM). Subsequently, participants will be further randomised into two groups: an intervention group receiving a dietary intervention targeting a daily protein intake of 1.2-1.5 g/kg/day (PRT-Pro), and a control group with no dietary intervention (PRT-only). The dietary protein intervention will include counselling sessions and the provision of protein-rich foods. DISCUSSION: This study aims to elucidate the effect of various PRT intensities and the supplementary effects of adequate dietary protein intake on muscle mass, muscle strength, and physical performance in frail older adults. The results will provide critical insights for scientists and healthcare professionals, facilitating the development of more effective strategies to combat sarcopenia and frailty in this population.

However, regular community-based lifestyle interventions often lack a culture-sensitive approach. The aim of this study was to assess the effects of a newly developed culture-sensitive lifestyle intervention on physical performance in non-Western Surinamese older adults. DESIGN: A randomized controlled trial. PARTICIPANTS: This study was conducted with 65 non-Western migrant participants (Surinamese, 65 ± 7 y, 91% female, 82% overweight or obese). INTERVENTION: The participants were allocated to the culture-sensitive lifestyle intervention (n = 35) or control group (n = 30). The six-month intervention consisted of an exercise training program and a nutritional program, both adapted to the cultural and personal needs of the participants. MEASUREMENTS: The primary outcome was physical performance, measured by 6-minute walking test. Secondary outcomes were timed-up-and-go, 30-seconds chair stand, knee-extension strength, single leg stand tests, appendicular lean soft tissue mass, fat mass, protein intake and daily physical activity. Linear mixed models were performed to assess intervention effects with significance set at p < 0.05. RESULTS: The intervention group improved physical performance by 12% from baseline 440 ± 62 m to 6 months 492 ± 73 m compared to 8% in control group from 438 ± 93 m to 471 ± 66 m (+25.5 m, 95%CI (3.2;47.9)},

abstract = {OBJECTIVES: Sufficient protein intake is important for older adults to prevent sarcopenia. Better insight into dietary characteristics may be helpful to improve daily protein intake. Therefore, this study aimed to compare characteristics of community-dwelling older adults with distinct amounts of daily protein intake. METHODS: Baseline data of older adults (age >55 years) from eight intervention studies were pooled. Protein intake was measured using 24-h recalls or 3-day food records. Participants were stratified into one of four different groups based on their habitual protein intake (<0.8 g per kilogram bodyweight per day (g/kg/d), 0.8-0.99 g/kg/d, 1.0-1.2 g/kg/d and >1.2 g/kg/d). Protein intake per meal, animal-versus plant-based protein intake, daily protein distribution patterns (e.g. spread or pulse) and the protein intake from distinct protein-rich food categories (meat, fish, dairy, grains and others) were assessed. RESULTS: Among 814 participants (69 ± 9 years, 54 % male), mean protein intake was 0.98 ± 0.30 g/kg/d. 28 % (n = 227) of the population had a protein intake <0.8 g/kg/d, 29 % (n = 240) 0.8-0.99 g/kg/d, 22 % (n = 179) 1.0-1.2 g/kg/d and 21 % (n = 168) >1.2 g/kg/d. Higher protein intake groups had a lower body weight and BMI and a higher energy intake per day. Although protein intake distribution patterns did not differ across groups, meals with >20 g or >0.4 g protein per kilogram bodyweight per meal more often occurred in the higher protein intake groups. Protein intake was the lowest at breakfast followed by lunch and dinner, in all groups. Higher protein intake groups consumed a higher proportion of animal-based protein sources. CONCLUSION: Distinct protein intake groups showed comparable intake distribution patterns, with lowest protein consumption at breakfast and highest at dinner. Nevertheless, the highest protein intake group more often consumed >20 gr of protein per meal, indicating that a focus on the absolute amount of protein per meal, particularly at breakfast, could further optimize daily protein intake in older adults.},

 require action to avoid a total health system infarct. Obesity 

 is largely challenged with caloric restriction and endurance 

 exercise, likely to be assisted by drugs. The older adults with 

 the highest obesity levels may face extreme loss of muscle mass 

 and increased risk of sarcopenic obesity.Within this context the 

 question of what is the protein requirement is extremely urgent. 

 RECENT FINDINGS: While the topic is essential, no trials have 

 directly assessed protein requirements for obesity. Therefore, 

 we will have to deal with more indirect evidence. Several 

 systematic reviews have appeared for obesity treatment involving 

 protein and a few randomized controlled trials during weight 

 loss are worth mentioning considering the amount of protein 

 needed, especially with increasing age. SUMMARY: Protein 

 requirements are hard to derive for obesity defined by BMI over 

 30 perse. During weight loss the rebuilding of the body is 

 likely to need at least 1.2 g/kg body weight/d with a maximum 

 weight of BMI 30, especially in the aged. Obesity might increase 

 protein requirements, however being obese with a healthy and 

 active lifestyle might result in normal protein requirements.},

abstract = {BACKGROUND: Sarcopenic obesity significantly burdens health and 

 autonomy. Strategies to intervene in or prevent sarcopenic 

 obesity generally focus on losing body fat and building or 

 maintaining muscle mass and function. For a lifestyle 

 intervention, it is important to consider psychological aspects 

 such as behavioral change techniques (BCTs) to elicit a 

 long-lasting behavioral change. PURPOSE: The study was carried 

 out to analyze BCTs used in exercise and nutritional 

 interventions targeting community-dwelling adults around 

 retirement age with sarcopenic obesity. METHODS: We conducted an 

 analysis of articles cited in an existing systematic review on 

 the effectiveness of exercise and nutritional interventions on 

 physiological outcomes in community-dwelling adults around 

 retirement age with sarcopenic obesity. We identified BCTs used 

 in these studies by applying a standardized taxonomy. RESULTS: 

 Only nine BCTs were identified. Most BCTs were not used 

 intentionally (82 %), and those used derived from the 

 implementation of lifestyle components, such as exercise classes 

 (``instructions on how to perform a behavior,'' ``demonstration 

 of the behavior,'' ``behavioral practice/rehearsal,'' and ``body 

 changes''). Only two studies used BCTs intentionally to 

 reinforce adherence in their interventions. CONCLUSIONS: Few 

 studies integrated BCTs in lifestyle interventions for 

 community-dwelling persons around retirement age with sarcopenic 

 obesity. Future studies on interventions to counteract 

 sarcopenic obesity should include well-established BCTs to 

 foster adherence and, therefore, their effectiveness.},

 condition, BMI less than 18 kg/m2, kidney failure with a no 

 dialysis code, or hepatic encephalopathy. Patients were randomly 

 assigned to one of four randomisation labels, corresponding with 

 two study groups (ie, standard or high protein; two labels per 

 group) in a 1:1:1:1 ratio through an interactive web-response 

 system. Randomisation was done via random permuted-block 

 randomisation in varying block sizes of eight and 12, stratified 

 by centre. Participants, care providers, investigators, outcome 

 assessors, data analysts, and the independent data safety 

 monitoring board were all blinded to group allocation. Patients 

 received isocaloric enteral feeds that contained 1·3 kcal/mL and 

 0·06 g of protein/mL (ie, standard protein) or 1·3 kcal/mL and 

 0·10 g of protein/mL (ie, high protein). The study-nutrition 

 intervention was limited to the time period during the patient's 

 ICU stay in which they required enteral feeding, with a maximum 

 of 90 days. The primary outcome was EuroQoL 5-Dimension 5-level 

 (EQ-5D-5L) health utility score at 30 days, 90 days, and 180 

 days after randomisation, adjusted for baseline EQ-5D-5L health 

 utility score. This trial was registered with ClinicalTrials.gov 

 (NCT04633421) and is closed to new participants. FINDINGS: 

 Between Nov 19, 2020, and April 14, 2023, 935 patients were 

 randomly assigned. 335 (35·8%) of 935 patients were female and 

 600 (64·2%) were male. 465 (49·7%) of 935 were assigned to the 

 standard protein group and 470 (50·3%) were assigned to the 

 high protein group. 430 (92·5%) of 465 patients in the standard 

 protein group and 419 (89·1%) of 470 patients in the high 

 protein group were assessed for the primary outcome. The primary 

 outcome, EQ-5D-5L health utility score during 180 days after 

 randomisation (assessed at 30 days, 90 days, and 180 days), was 

 lower in patients allocated to the high protein group than in 

 those allocated to the standard protein group, with a mean difference of -0·05 (95% CI -0·10 to -0·01; p=0·031). Regarding 

 safety outcomes, the probability of mortality during the entire 

 follow-up was 0·38 (SE 0·02) in the standard protein group and 

 0·42 (0·02) in the high protein group (hazard ratio 1·14, 95% CI 0·92 to 1·40; p=0·22). There was a higher incidence of 

 symptoms of gastrointestinal intolerance in patients in the high protein group (odds ratio 1·76, 95% CI 1·06 to 2·92; p=0·030). 

 Incidence of other adverse events did not differ between groups. 

 INTERPRETATION: High enteral protein provision compared with 

 standard enteral protein provision resulted in worse 

 health-related quality of life in critically ill patients and 

 did not improve functional outcomes during 180 days after ICU 

 admission. FUNDING: Netherlands Organisation for Healthcare

 long-lasting behavioral change. PURPOSE: The study was carried 

 out to analyze BCTs used in exercise and nutritional 

 interventions targeting community-dwelling adults around 

 retirement age with sarcopenic obesity. METHODS: We conducted an 

 analysis of articles cited in an existing systematic review on 

 the effectiveness of exercise and nutritional interventions on 

 physiological outcomes in community-dwelling adults around 

 retirement age with sarcopenic obesity. We identified BCTs used 

 in these studies by applying a standardized taxonomy. RESULTS: 

 Only nine BCTs were identified. Most BCTs were not used 

 intentionally (82 %), and those used derived from the 

 implementation of lifestyle components, such as exercise classes 

 (``instructions on how to perform a behavior,'' ``demonstration 

 of the behavior,'' ``behavioral practice/rehearsal,'' and ``body 

 changes''). Only two studies used BCTs intentionally to 

 reinforce adherence in their interventions. CONCLUSIONS: Few 

 studies integrated BCTs in lifestyle interventions for 

 community-dwelling persons around retirement age with sarcopenic 

 obesity. Future studies on interventions to counteract 

 sarcopenic obesity should include well-established BCTs to 

 foster adherence and, therefore, their effectiveness.},

abstract = {OBJECTIVES: Adherence to lifestyle interventions is crucial for the treatment of obesity. However, there is little research about adherence to lifestyle interventions in persons around retirement age. The objectives of this study are (1) to identify factors associated with the adherence to resistance training and a hypocaloric diet and (2) to describe the association between adherence and changes in body composition outcome parameters.nnDESIGN: This secondary data analysis included three randomized controlled trials.nnSETTING & PARTICIPANTS: The inclusion criteria of the participants were an age of 55-75 years, a BMI ≥ 25 kg/m and receiving both a hypocaloric diet and resistance training. All participants were residing in the community.nnMEASUREMENTS: Adherence to hypocaloric diet was measured through the mean dietary intake on the basis of a 3-day dietary record. If the participant consumed at least 600 kcal less than the individual caloric requirements, they were considered adherent. Adherence to resistance training was achieved if ≥67% of the recommended training sessions were attended over the course of the study periods.nnRESULTS: 232 participants were included, 47.0% female, mean age 64.0 (±5.5) years. 80.2% adhered to resistance training and 51.3% adhered to a hypocaloric diet. Older age (Beta 0.41; 95% CI 0.05, 0.78; p = 0.028) and male sex (Beta 7.7; 95% CI 3.6, 11; p < 0.001) were associated with higher resistance training adherence. A higher BMI at baseline (Beta 6.4; 95% CI 3.6, 9.2; p < 0.001) and male sex (Beta 65; 95% CI 41, 88; p < 0.001) were associated with higher adherence to hypocaloric diet.nnCONCLUSION: We identified several associated factors (sex, age and BMI at baseline) that should be considered to promote adherence in future lifestyle intervention studies in persons around retirement age. We recommend including behavior change techniques in lifestyle interventions and consider sex-specific interventions to improve the adherence of women.},

 present article aimed to (i) define a list of factors related

 (iii) evaluate their relevance and the potential research gaps 

 by consulting an expert panel. From 4746 articles screened, 240 

 articles were selected for extraction of the factors associated 

 with SO. Factors were classified according to their frequency in 

 the literature. Clinical conditions were also recorded. Then, 

 they were evaluated by a panel of expert for evaluation of their 

 relevance in SO development. Experts also suggested additional 

 factors. Thirty-nine unique factors were extracted from the 

 papers and additional eleven factors suggested by a panel of 

 experts in the SO field. The frequency in the literature showed 

 insulin resistance, dyslipidemia, lack of exercise training, 

 inflammation and hypertension as the most frequent factors 

 associated with SO whereas experts ranked low spontaneous 

 physical activity, protein and energy intakes, low exercise 

 training and aging as the most important. Although literature 

 and expert panel presented some differences, this first list of 

 associated factors could help to identify patients at risk of 

 SO. Further work is needed to confirm the contribution of 

 factors associated with SO among the population overtime or in 

 randomized controlled trials to demonstrate causality.},

 fat mass (obesity) and low skeletal muscle mass and function 

 (sarcopenia). The identification and classification of factors 

 related to SO would favor better prevention and diagnosis. The 

 present article aimed to (i) define a list of factors related 

 with SO based on literature analysis, (ii) identify clinical 

 conditions linked with SO development from literature search and 

 (iii) evaluate their relevance and the potential research gaps 

 by consulting an expert panel. From 4746 articles screened, 240 

 articles were selected for extraction of the factors associated 

 with SO. Factors were classified according to their frequency in 

 the literature. Clinical conditions were also recorded. Then, 

 they were evaluated by a panel of expert for evaluation of their 

 relevance in SO development. Experts also suggested additional 

 factors. Thirty-nine unique factors were extracted from the 

 papers and additional eleven factors suggested by a panel of 

 experts in the SO field. The frequency in the literature showed 

 insulin resistance, dyslipidemia, lack of exercise training, 

 inflammation and hypertension as the most frequent factors 

 associated with SO whereas experts ranked low spontaneous 

 physical activity, protein and energy intakes, low exercise 

 training and aging as the most important. Although literature 

 and expert panel presented some differences, this first list of 

 associated factors could help to identify patients at risk of 

 SO. Further work is needed to confirm the contribution of 

 factors associated with SO among the population overtime or in

abstract = {BACKGROUND: Chronic low-grade inflammatory profile (CLIP) is one of the pathways involved in type 2 diabetes (T2D). Currently, there is limited evidence for ameliorating effects of combined lifestyle interventions on CLIP in type 2 diabetes. We investigated whether a 13-week combined lifestyle intervention, using hypocaloric diet and resistance exercise plus high-intensity interval training with or without consumption of a protein drink, affected CLIP in older adults with T2D.nnMETHODS: In this post-hoc analysis of the PROBE study 114 adults (≥55 years) with obesity and type 2 (pre-)diabetes had measurements of C-reactive protein (CRP), pro-inflammatory cytokines interleukin (IL)-6, tumor-necrosis-factor (TNF)-α, and monocyte chemoattractant protein (MCP)-1, anti-inflammatory cytokines IL-10, IL-1 receptor antagonist (RA), and soluble tumor-necrosis-factor receptor (sTNFR)1, adipokines leptin and adiponectin, and glycation biomarkers carboxymethyl-lysine (CML) and soluble receptor for advanced glycation end products (sRAGE) from fasting blood samples. A linear mixed model was used to evaluate change in inflammatory biomarkers after lifestyle intervention and effect of the protein drink. Linear regression analysis was performed with parameters of body composition (by dual-energy X-ray absorptiometry) and parameters of insulin resistance (by oral glucose tolerance test).nnRESULTS: There were no significant differences in CLIP responses between the protein and the control groups. For all participants combined, IL-1RA, leptin and adiponectin decreased after 13 weeks (p = 0.002, p < 0.001 and p < 0.001), while ratios TNF-α/IL-10 and TNF-α/IL-1RA increased (p = 0.003 and p = 0.035). CRP increased by 12 % in participants with low to average CLIP (pre 1.91 ± 0.39 mg/L, post 2.13 ± 1.16 mg/L, p = 0.006) and decreased by 36 % in those with high CLIP (pre 5.14 mg/L ± 1.20, post 3.30 ± 2.29 mg/L, p < 0.001). Change in leptin and IL-1RA was positively associated with change in fat mass (β = 0.133, p < 0.001; β = 0.017, p < 0.001) and insulin resistance (β = 0.095, p = 0.024; β = 0.020, p = 0.001). Change in lean mass was not associated with any of the biomarkers.nnCONCLUSION: 13 weeks of combined lifestyle intervention, either with or without protein drink, reduced circulating adipokines and anti-inflammatory cytokine IL-1RA, and increased inflammatory ratios TNF-α/IL-10 and TNF-α/IL-1RA in older adults with obesity and T2D. Effect on CLIP was inversely related to baseline inflammatory status.},

 investigate the prevalence of sarcopenia and SO and their 

 association with all-cause mortality. Design, Setting, and 

 Participants: This large-scale, population-based cohort study 

 assessed participants from the Rotterdam Study from March 1, 

 2009, to June 1, 2014. Associations of sarcopenia and SO with 

 all-cause mortality were studied using Kaplan-Meier curves, Cox 

 proportional hazards regression, and accelerated failure time 

 models fitted for sex, age, and body mass index (BMI). Data 

 analysis was performed from January 1 to April 1, 2023. 

 Exposures: The prevalence of sarcopenia and SO, measured based on 

 handgrip strength and body composition (BC) (dual-energy x-ray 

 absorptiometry) as recommended by current consensus criteria, 

 with probable sarcopenia defined as having low handgrip strength 

 and confirmed sarcopenia and SO defined as altered BC (high fat 

 percentage and/or low appendicular skeletal muscle index) in 

 addition to low handgrip strength. Main Outcome and Measure: The 

 primary outcome was all-cause mortality, collected using linked 

 mortality data from general practitioners and the central 

 municipal records, until October 2022. Results: In the total 

 population of 5888 participants (mean [SD] age, 69.5 [9.1] years; 

 mean [SD] BMI, 27.5 [4.3]; 3343 [56.8%] female), 653 (11.1%; 

 95% CI, 10.3%-11.9%) had probable sarcopenia and 127 (2.2%; 

 95% CI, 1.8%-2.6%) had confirmed sarcopenia. Sarcopenic 

 obesity with 1 altered component of BC was present in 295 

 participants (5.0%; 95% CI, 4.4%-5.6%) and with 2 altered 

 components in 44 participants (0.8%; 95% CI, 0.6%-1.0%). An 

 increased risk of all-cause mortality was observed in 

 participants with probable sarcopenia (hazard ratio [HR], 1.29; 

 95% CI, 1.14-1.47) and confirmed sarcopenia (HR, 1.93; 95% CI, 

 1.53-2.43). Participants with SO plus 1 altered component of BC 

 (HR, 1.94; 95% CI, 1.60-2.33]) or 2 altered components of BC 

 (HR, 2.84; 95% CI, 1.97-4.11) had a higher risk of mortality 

 than those without SO. Similar results for SO were obtained for 

 participants with a BMI of 27 or greater. Conclusions and 

 Relevance: In this study, sarcopenia and SO were found to be 

 prevalent phenotypes in older people and were associated with 

 all-cause mortality. Additional alterations of BC amplified this 

 risk independently of age, sex, and BMI. The use of low muscle 

 strength as a first step of both diagnoses may allow for early

abstract = {IMPORTANCE: Sarcopenia and obesity are 2 global concerns associated with adverse health outcomes in older people. Evidence on the population-based prevalence of the combination of sarcopenia with obesity (sarcopenic obesity [SO]) and its association with mortality are still limited.nnOBJECTIVE: To investigate the prevalence of sarcopenia and SO and their association with all-cause mortality.nnDESIGN, SETTING, AND PARTICIPANTS: This large-scale, population-based cohort study assessed participants from the Rotterdam Study from March 1, 2009, to June 1, 2014. Associations of sarcopenia and SO with all-cause mortality were studied using Kaplan-Meier curves, Cox proportional hazards regression, and accelerated failure time models fitted for sex, age, and body mass index (BMI). Data analysis was performed from January 1 to April 1, 2023.nnEXPOSURES: The prevalence of sarcopenia and SO, measured based on handgrip strength and body composition (BC) (dual-energy x-ray absorptiometry) as recommended by current consensus criteria, with probable sarcopenia defined as having low handgrip strength and confirmed sarcopenia and SO defined as altered BC (high fat percentage and/or low appendicular skeletal muscle index) in addition to low handgrip strength.nnMAIN OUTCOME AND MEASURE: The primary outcome was all-cause mortality, collected using linked mortality data from general practitioners and the central municipal records, until October 2022.nnRESULTS: In the total population of 5888 participants (mean [SD] age, 69.5 [9.1] years; mean [SD] BMI, 27.5 [4.3]; 3343 [56.8%] female), 653 (11.1%; 95% CI, 10.3%-11.9%) had probable sarcopenia and 127 (2.2%; 95% CI, 1.8%-2.6%) had confirmed sarcopenia. Sarcopenic obesity with 1 altered component of BC was present in 295 participants (5.0%; 95% CI, 4.4%-5.6%) and with 2 altered components in 44 participants (0.8%; 95% CI, 0.6%-1.0%). An increased risk of all-cause mortality was observed in participants with probable sarcopenia (hazard ratio [HR], 1.29; 95% CI, 1.14-1.47) and confirmed sarcopenia (HR, 1.93; 95% CI, 1.53-2.43). Participants with SO plus 1 altered component of BC (HR, 1.94; 95% CI, 1.60-2.33]) or 2 altered components of BC (HR, 2.84; 95% CI, 1.97-4.11) had a higher risk of mortality than those without SO. Similar results for SO were obtained for participants with a BMI of 27 or greater.nnCONCLUSIONS AND RELEVANCE: In this study, sarcopenia and SO were found to be prevalent phenotypes in older people and were associated with all-cause mortality. Additional alterations of BC amplified this risk independently of age, sex, and BMI. The use of low muscle strength as a first step of both diagnoses may allow for early identification of individuals at risk for premature mortality.},
