Background: Demographic transition has resulted in population aging, which has led to advancement in multiple geriatric problems including cognitive impairment (CI) and depression. Objectives: The objective was to find the prevalence and determinants of CI and depression in the rural elderly population. Materials and Methods: This was a community-based cross-sectional study conducted in a rural area. The prevalence of CI was measured using the Mini-Mental State Examination scale and depression was assessed using the Geriatric Depression Scale. The data so collected were analyzed using PSPP software. Results: The mean age of the study participants was 67.47 ± 6.43 years. The prevalence of CI and geriatric depression was found to be 36% (153/425) and 29.1% (124/425), respectively. Variables which were found to have independent significant association on multivariate analysis with CI were literacy, memory complaints, and depression. For geriatric depression, an independent association was seen with literacy, socioeconomic status, memory complaints, stress in the family, and presence of CI. CI and geriatric depression were found to be strongly correlated with each other (r = −0.252, P < 0.001). Conclusions: Almost one-third of the geriatric population is suffering from depression (29.1%) and CI (36%). This necessitates for accurate and timely diagnosis, so as to ensure proper care and support to the elderly population with emphasis on geriatric mental health care.
