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.
优化蛋白质摄入量是预防老年人肌肉质量和力量随年龄增长而丧失的新策略。对于来自少数民族群体的老年人来说，这种策略仍然缺失。由于几个社会文化因素，这些人群的蛋白质摄入量预计与大多数人群不同。因此，本研究调查了荷兰少数民族老年人的蛋白质摄入量以及影响蛋白质摄入量的潜在行为和环境因素。我们使用 ANCOVA 分析了来自城市环境中的健康生活（HELIUS）队列的频率问卷（FFQ）数据，以描述荷兰少数民族老年人的膳食蛋白质摄入量（N=1415，年龄>55 岁，非洲苏里南人、南亚苏里南人、摩洛哥人和土耳其人）。此外，我们在来自同一少数民族群体的老年人中进行了焦点小组讨论（N=69），以发现影响蛋白质摄入量的行为和环境因素；除了土耳其男性（达到 91%）外，40-60%的受试者没有达到维持肌肉质量所需的最低膳食蛋白质推荐量（1.0 克/公斤体重/天（BW/天））。蛋白质的主要来源来自动物产品，且具有民族特异性。焦点小组的参与者对蛋白质及其在衰老中的作用知之甚少。这些人群的主要关注点似乎是饮食中蛋白质的摄入量和不规律的饮食模式。在这些人群中优化蛋白质摄入量需要一种文化敏感的方法，该方法需要考虑特定的蛋白质产品类型和社会文化因素。
