Little is known about food security transition over time and the influence on nutrient intake among homebound seniors. Data are from 262 homebound older adults who received home‐delivered meals and completed in‐home assessments at two time‐points (1 year interval). Dietary intake was determined through 3 24‐hour dietary recalls at each time‐point. NDS‐R software was used to calculate nutrient intake; energy‐adjusted multiple regression models examined variables associated with nutrient intake at time 2. Food security stability was reported by 39% (n = 103), persistent risk for food insecurity by 26.3 %, and persistent food insecurity by 2.3%; 23% became less food secure; and 9% became more food secure. Nutrient intake at baseline predicted intake 1 year later. Food security transition was associated with time 2 intakes of energy, fiber, niacin, and phosphorus. Although food security transition is a predictor of energy‐adjusted dietary intake among homebound older adults, baseline dietary intake is the most significant predictor of dietary intake one year later. Thus, it is critical to monitor both food security status and dietary intake in vulnerable older populations.
