Abstract

The purpose of this study was to assess the prevalence of frailty and nutritional status among older adults. This population-based cross-sectional study was conducted in 163 subjects aged 60-88 years, from Hyderabad City, South India. Data were obtained on sociodemographic details and anthropometry and biochemical parameters. Dietary intake was assessed by a three-day 24 h dietary recall, and the probability of adequacy (PA) was calculated using the estimated average requirements. Frailty indicators were as follows: handgrip strength was measured by using a Jamar dynamometer, gait speed was measured by a ten-meter length walk test, and low physical activity level, weight loss, and exhaustion were assessed using a questionnaire. Among the study population, 20% of the participants were frail and 80% were nonfrail. The prevalence of frailty is higher in older (30.1%) than the younger (12.2%) age groups, and it is more so in women (32.4%) than in men (10.1%). The lower educational status and income were associated with frailty. The PA of most of the nutrients was low in the frail group. Noticeably, the mean PA (MPA) across the fourteen micronutrients was significantly higher in nonfrail (38%) compared to the frail group (25%). The prevalence of frailty was higher in the lowest tertile of most of the food groups and nutrient intake compared to the highest tertile. The study revealed a 20% prevalence of frailty among urban older adults and provided evidence that inadequate intake of nutrients is independently associated with frailty.

摘要

本研究的目的是评估老年人衰弱和营养状况的患病率。这项基于人群的横断面研究在来自印度南部海得拉巴市的163名60 - 88岁的受试者中进行。获取了社会人口学细节、人体测量学以及生化参数的数据。通过三天24小时饮食回顾评估饮食摄入量,并使用估计平均需求量计算充足概率(PA)。衰弱指标如下:使用Jamar测力计测量握力,通过十米步行测试测量步速,使用问卷评估低身体活动水平、体重减轻和疲惫程度。在研究人群中,20%的参与者衰弱,80%不衰弱。衰弱的患病率在老年组(30.1%)高于年轻组(12.2%),在女性(32.4%)中比男性(10.1%)更高。较低的教育水平和收入与衰弱相关。衰弱组中大多数营养素的充足概率较低。值得注意的是,与衰弱组(25%)相比,非衰弱组(38%)中十四种微量营养素的平均充足概率显著更高。与最高三分位数相比,大多数食物组和营养素摄入量处于最低三分位数时,衰弱的患病率更高。该研究揭示城市老年人中衰弱的患病率为20%,并提供了证据表明营养素摄入不足与衰弱独立相关。
