Predictors of self-initiated, healthful dietary change.
J Am Diet Assoc. 2001 Jul; 101(7):762-6.JA

Abstract

OBJECTIVE

To examine demographic and psychosocial factors that predict healthful dietary change.

DESIGN

A cohort study, examining how factors assessed at baseline predicted change in fat-related dietary habits and fruit and vegetable intakes 2 years later.

PARTICIPANTS

Participants were recruited in 1995 and 1996 by random-digit dialing (response rate 0.63), and followed-up in 1997 and 1998 (follow-up rate 0.82). The final sample included 336 men and 502 women.

MAIN OUTCOME MEASURES

Fruit and vegetable intake and fat-related dietary patterns, measured by telephone-administered surveys.

STATISTICAL ANALYSES

Chi2 tests and linear regression were used to test associations of baseline characteristics with dietary change.

RESULTS

Fat intake (energy from fat) decreased by approximately 2 percentage points and fruits and vegetables intake increased by 0.17 servings per day (both P<.001). Changes were significantly larger among women and persons who were well educated. Persons in the maintenance stage of change and persons who believed there was a strong relationship between diet and cancer made the largest dietary changes. Use of food labels was strongly associated with fat reduction, but not with increases in fruits and vegetables.

APPLICATIONS

These results suggest that food labels are useful for helping people reduce fat intake, that interventions should target persons at all stages of dietary change, and that new efforts are needed to reach men and persons who are less well educated.
