title: Applying the theory of planned behavior to fruit and vegetable consumption by older adults.
abstract: This study applied the Theory of Planned Behavior to fruit and vegetable intake among older adults. A cross-sectional questionnaire was administered to older adults (N = 205, mean age = 77 years) at senior centers. Most were women (74%), white (77%), and had >/= 12 years of education. Regression analyses showed that the theory constructs explained more than 40% and 18% (p < 0.0001) of the variance in intention and reported intake of fruits and vegetables, respectively. Perceived behavioral control was most important in explaining both intention and intake, followed by attitudes and subjective norms. Important control beliefs were related to convenience, preferences, time, and availability when eating out. These beliefs should be addressed in education for older adults to increase fruit and vegetable intake.
