To estimate the prevalence of malnutrition among free-living elderly in a rural population of south India.
Cross-sectional study. Nutritional status was assessed using the Mini Nutritional Assessment (MNA) questionnaire, which is an eighteen-item nutritional screening instrument used in the elderly.
Kaniyambadi block, a rural development block in the state of Tamil Nadu, south India.
Community-dwelling elderly (aged 60 years and above).
As evaluated by the MNA, 14 % of the 227 subjects were malnourished and 49 % were at risk of malnourishment. No significant difference was found between men and women. The majority of the elderly were living with their children, had no income and consumed three meals per day. Older age (P < 0.001), decreased food intake (P < 0.001) and consuming fewer meals (P < 0.001) were independently associated with lower MNA scores.
More than 60 % of the subjects had low MNA scores (<23.5) indicating that deficient protein-energy intake is common among rural elderly of south India and requires more attention.
评估印度南部农村地区自由生活的老年人的营养不良患病率。
横断面研究。营养状况使用 Mini Nutritional Assessment（MNA）问卷进行评估，该问卷是一种用于老年人的十八项营养筛查工具。
印度南部泰米尔纳德邦卡尼亚扬巴迪区。
社区居住的老年人（年龄 60 岁及以上）。
根据 MNA 评估，227 名受试者中有 14%存在营养不良，49%存在营养不良风险。男女之间没有明显差异。大多数老年人与子女同住，没有收入，每天吃三顿饭。年龄较大（P < 0.001）、食物摄入量减少（P < 0.001）和用餐次数减少（P < 0.001）与较低的 MNA 评分独立相关。
超过 60%的受试者 MNA 评分较低（<23.5），表明印度南部农村老年人蛋白质-能量摄入不足很常见，需要引起更多关注。
