Increased fruit and vegetable intake among older adults participating in Kentucky’s congregate meal site program

Abstract

ABSTRACTThe purpose of this study was to determine if the amount and variety of fruits and vegetables consumed increased among community-dwelling older adults participating in Kentucky’s congregate meal site program following a series of five nutrition education lessons. A convenience sample of older adults attending senior centers (n = 35)—two intervention (n = 19) and two control (n = 16) centers—participated in this quasi-experimental pilot study. Following the intervention there was a significant increase in actual fruit and vegetable intake in the intervention group (p < .05) as assessed by platewaste measurements of the congregate lunch meal. In addition, from pre- to post-intervention, a trend towards increased self-reported intake in the variety of fruit and vegetables was observed among the intervention group. As well, a significant increase in the number of days intervention participants self-reported consuming at least 4.5 cups of fruits and vegetables in the last 7 days (2.44 ± 2.09 days to 4.28 ± 1.99 days (p = .004)) was observed; and knowledge pertaining to phytochemicals increased (p < .05). The phytochemical index (PI) score of the lunch meal, taking into account that the older adults' consumption of meal components, including phytochemical-rich foods, was 26.9. Overall, study results indicated that a short theory-based nutrition education program offered to community-dwelling older adults was linked to an increase in fruit and vegetable consumption and phytochemical knowledge.
