Objective: To examine the prevalence of sarcopenia and its association with protein intake in men and women in a multi-ethnic population. Design: We used cross-sectional data from the HELIUS (Healthy Life in an Urban Setting) study, which includes nearly 25,000 participants (aged 18–70 years) of Dutch, South-Asian Surinamese, African Surinamese, Turkish, Moroccan, and Ghanaian ethnic origin. For the current study, we included 5161 individuals aged 55 years and older. Sarcopenia was defined according to the EWGSOP2. In a subsample (N = 1371), protein intake was measured using ethnic-specific Food Frequency Questionnaires. Descriptive analyses were performed to study sarcopenia prevalence across ethnic groups in men and women, and logistic regression analyses were used to study associations between protein intake and sarcopenia. Results: Sarcopenia prevalence was found to be sex- and ethnic-specific, varying from 29.8% in Turkish to 61.3% in South-Asian Surinamese men and ranging from 2.4% in Turkish up to 30.5% in South-Asian Surinamese women. Higher protein intake was associated with a 4% lower odds of sarcopenia in the subsample (OR = 0.96, 95%-CI: 0.92–0.99) and across ethnic groups, being only significant in the South-Asian Surinamese group. Conclusion: Ethnic differences in the prevalence of sarcopenia and its association with protein intake suggest the need to target specific ethnic groups for prevention or treatment of sarcopenia.

Optimizing protein intake is a novel strategy to prevent age associated loss of muscle mass and strength in older adults. Such a strategy is still missing for older adults from ethnic minority populations. Protein intake in these populations is expected to be different in comparison to the majority of the population due to several socio-cultural factors. Therefore, the present study examined the dietary protein intake and underlying behavioral and environmental factors affecting protein intake among older adults from ethnic minorities in the Netherlands. We analyzed frequency questionnaire (FFQ) data from the Healthy Life in an Urban Setting (HELIUS) cohort using ANCOVA to describe dietary protein intake in older adults from ethnic minorities in the Netherlands (N = 1415, aged >55 years, African Surinamese, South Asian Surinamese, Moroccan, and Turkish). Additionally, we performed focus groups among older adults from the same ethnic minority populations (N = 69) to discover behavioral and environmental factors affecting protein intake; 40-60% of the subjects did not reach minimal dietary protein recommendations needed to maintain muscle mass (1.0 g/kg bodyweight per day (BW/day)), except for Turkish men (where it was 91%). The major sources of protein originated from animal products and were ethnic specific. Participants in the focus groups showed little knowledge and awareness about protein and its role in aging. The amount of dietary protein and irregular eating patterns seemed to be the major concern in these populations. Optimizing protein intake in these groups requires a culturally sensitive approach, which accounts for specific protein product types and sociocultural factors.

Trends in eiwittransitie kunnen regionaal verschillen. In groeiende economieën verschuiven diëten wereldwijd van plantaardige naar dierlijke eiwitten. In veel economisch ontwikkelde regio's gebeurt echter het tegenovergestelde vanwege de zorg voor milieu en gezondheid. Wij onderzochten de relatie tussen vijf drijvende krachten en eiwittransitietrends zoals deze worden ervaren door jongvolwassenen in ontwikkelde regio's in China (Shanghai) en Nederland (Amsterdam, lees: de Randstad). De onderzochte drijvende krachten waren: milieubewustzijn; het beleid; cultuur; geld; en gezondheid. De gegevens zijn verkregen door 200 vragenlijsten te laten beantwoorden in beide regio's. De resultaten geven aan dat jongvolwassenen in Shanghai meer dierlijke eiwitten consumeren dan plantaardige eiwitten, maar dat er een verandering naar plantaardige eiwitten is ingezet, terwijl de trend van jongvolwassenen in Amsterdam om plantaardig eiwit te consumeren al verder ontwikkeld is. De rangschikking van de drijvende krachten in Shanghai was Geld＞ Milieubewustzijn＞ Gezondheid＞ Cultuur＞ Beleid, en in Amsterdam Gezondheid＞ Milieubewustzijn＞ Geld＞ Beleid＞ Cultuur. Eiwitkeuzes in de voeding van jongvolwassenen worden dus in Shanghai door andere drijvende krachten bepaald dan in Amsterdam
