Functional status and its associated factors among community-dwelling older adults in rural Nepal: findings from a cross-sectional study

BACKGROUND: The high burden of chronic conditions, coupled with various physical, mental, and psychosocial changes that accompany the phenomenon of aging, may limit the functional ability of older adults. This study aims to assess the prevalence of poor functional status and investigate factors associated with poor functional status among community-dwelling older adults in rural communities of eastern Nepal. METHODS: Data on 794 older adults aged ≥ 60 years from a previous community-based cross-sectional study was used. Participants were recruited from rural municipalities of Morang and Sunsari districts of eastern Nepal using multi-stage cluster sampling. Functional status was assessed in terms of participants’ ability to perform activities of daily living using the Barthel Index. Covariates included sociodemographic characteristics, lifestyle factors, and self-reported chronic conditions. A binary logistic regression model was used to investigate factors associated with poor functional status. RESULTS: The overall prevalence of poor functional status was 8.3 % (male: 7.0 % and female: 9.6 %), with most dependence noted for using stairs (17.3 %), followed by dressing (21.9 %) on Barthel Index. In the adjusted model, oldest age group (odds ratio [OR] = 2.83, 95 %CI: 1.46, 5.50), those unemployed (OR = 2.41, 95 %CI: 1.26, 4.65), having memory/concentration problems (OR = 2.32, 95 %CI: 1.30, 4.13), depressive symptoms (OR = 2.52, 95 %CI: 1.28, 4.95), and hypertension (OR = 1.78, 95 %CI: 1.03, 3.06) had almost or more than two times poor functioning. CONCLUSIONS: One in 12 older adults had poor functional status as indicated by their dependency on the items of the Barthel Index; those in the oldest age bracket were more likely to exhibit poor functional status. We suggest future studies from other geographies of the country to supplement our study from the rural setting for comprehensive identification of the problem, which could guide the development of prevention strategies and comprehensive interventions for addressing the unmet needs of the older adults for improving functional status.
