This study aims to explore the single and joint effects of depression and malnutrition on the incidence of first fall onset in a Chinese community-dwelling elderly population. This cohort study consisted of 739 residents without a history of falls who were aged 60 years and older (mean age: 67.08 ± 5.79 years, female: 58.2%). Depression was defined with the Geriatric Depression Scale (GDS)-30; a score of ≥11 was considered to be depressed, while malnutrition was defined with the Mini Nutritional Assessment where a score <17 was defined as malnourished. Over a 2-year follow-up period, older adults who experienced at least one fall were allocated to the first fall onset group. The prevalence of baseline falls was 21.36%. During the 2-year follow-up, incidence of first fall onset was 13.13%. After adjusting for all confounders, depression alone (adjusted odds ratio [OR] = 3.545, 95% confidence interval [CI] = 1.318–9.535) and malnutrition alone (adjusted OR = 2.204, 95% CI = 1.183–4.108) were observed to be independent risk factors for first fall onset, while comorbidity of depression and malnutrition showed progressively increased risk of promoting first fall (adjusted OR = 8.161, 95% CI = 3.591–18.545) than those with only depression or malnutrition or without both depression and malnutrition. Malnutrition mediated 56% effects in the association between depression and first fall onset, while depression mediated 76% effects in the promoting role of malnutrition in first fall. Depression and malnutrition were found to be independent causes for promoting first fall, while mental health and nutrition should be treated as commonly prior interventions to delay first fall onset. Meanwhile, for malnourished Chinese community-dwelling older adults, avoidance or treatment of depression should be addressed at first.
