Abstract

Objective: The study aimed to explore the association between body mass index (BMI) and cognitive function among older adults in India.

Methods: Cross-sectional data on 21,000 older adults aged 60 years and older from the first wave of the Longitudinal Ageing Study of India (LASI), conducted in India during 2017-18, were used. Bivariate analysis and multivariate linear regression models were applied. The cognition tests include memory, orientation, arithmetic function, executive function, and object naming.

Results: The mean overall cognition score was 24.6 in the study population. Further, BMI status showed a significant and positive association with cognition. The association of underweight with poor cognition (β=-0.72; 95% CI = -0.89, -0.54) whereas overweight (β = 0.57; 95% CI = 0.39, 0.75) and obese (β = 0.97; 95% CI = 0.68, 1.26) with better cognition remained statistically significant after adjusting for sociodemographic, health-related behavior, and health covariates. The mean cognition score of female older adults was always lower than male older adults with normal BMI, irrespective of their BMI categories.

Conclusions: This study shows that an underweight BMI is associated with poor cognition in both male and female older adults. In the context of providing health care for older individuals, underweight individuals should be given more attention in India.

印度老年人身体质量指数与认知功能之间的关系：一项横断面研究的结果。

研究目的研究旨在探讨印度老年人的体重指数（BMI）与认知功能之间的关系：研究使用了 2017-18 年期间在印度开展的印度纵向老龄化研究（LASI）第一波中 21000 名 60 岁及以上老年人的横断面数据。应用了双变量分析和多变量线性回归模型。认知测试包括记忆、定向、算术功能、执行功能和物体命名：结果：研究人群的平均认知总分为 24.6 分。此外，体重指数与认知能力呈显著正相关。体重不足与认知能力差的关系（β=-0.72；95% CI =-0.89，-0.54），而超重（β=0.57；95% CI =0.39，0.75）和肥胖（β=0.97；95% CI =0.68，1.26）与认知能力较好的关系在调整社会人口学、健康相关行为和健康协变量后仍具有统计学意义。女性老年人的平均认知得分总是低于体重指数正常的男性老年人，无论他们的体重指数属于哪个类别：本研究表明，体重指数过低与男性和女性老年人的认知能力差有关。在印度，为老年人提供医疗保健服务时，体重不足者应得到更多关注。

期刊介绍： Experimental Aging Research is a life span developmental and aging journal dealing with research on the aging process from a psychological and psychobiological perspective. It meets the need for a scholarly journal with refereed scientific papers dealing with age differences and age changes at any point in the adult life span. Areas of major focus include experimental psychology, neuropsychology, psychobiology, work research, ergonomics, and behavioral medicine. Original research, book reviews, monographs, and papers covering special topics are published.
