Psychosocial correlates of dietary intake among overweight and obese men.
OBJECTIVE
To investigate the relationship between theoretically based psychosocial constructs and dietary components among overweight men.


METHODS
Participants were 441 men (BMI M = 34.2). Psychosocial constructs included self-efficacy, decisional balance, social support, and behavior change strategies. Dietary components were fat, fiber, and fruit and vegetable intake.


RESULTS
All significant findings were in the expected direction. Multiple regression models indicated that the psychosocial factors accounted for the most variance in vegetable intake (R(2)=.13) and the least variance in fat (R(2)=.05).


CONCLUSIONS
Theoretically based psychosocial constructs were related to overweight men's dietary intake and have potential for use in tailored behavior-change interventions.
