Objective: To examine the association of proportion of daily energy consumed in the evening with weight change over 10 y of follow-up.
Design: The data used were from the First National Health and Nutrition Examination Survey (NHANES I, 1971-75) Epidemiologic Follow-up Study (NHEFS, 1982-84). The analytic cohort included 2580 men and 4567 women aged 25-74 y at baseline (NHANES I, 1971-75). The proportion of energy consumed in the evening (after 5 pm) was estimated from a 24 h dietary recall obtained a baseline. Weight change was defined as the difference between the follow-up and baseline weights.
Results: Mean +/- s.e. of percent energy from evening food intake was 46 +/- 0.29 in the analytic cohort. After adjustment for multiple covariates, percent energy from evening food intake and weight change were unrelated in both men and women.
Conclusion: Extent of evening eating was not a significant predictor of 10 y weight change in the NHEFS cohort.
