DIETARY FACTORS IN RELATION TO WEIGHT CHANGE AMONG MEN AND WOMEN FROM2 SOUTHEASTERN NEW-ENGLAND COMMUNITIES

OBJECTIVE: Dietary factors, independent of fetal energy, may be import ant in promoting obesity. We examined prospectively the relationship b etween baseline diet composition and weight gain among adult men and w omen from southeastern New England. DESIGN: The prospective associatio n of nutrient consumption and weight change was examined in a randomly selected cohort examined four years apart. SUBJECTS: Adults aged 18 t hrough 64 years from two communities in Southeastern New England were randomly selected for the study after being interviewed in their homes . The present investigation is based on a subgroup of 465 individuals who completed a food-frequency questionnaire in 1986 or 1987 and were reinterviewed four years later. STATISTICAL ANALYSES: Multiple regress ion analyses were used to determine the association of weight change w ith different nutrients and food groups after adjusting for age, smoki ng status, baseline body mass index, physical activity lever, and tota l energy. RESULTS: Total energy was positively associated with weight gain and age was inversely associated with weight gain. None of the nu trients or food groups were significantly related to weight gain. CONC LUSIONS: These findings indicate that weight gain increased with incre asing baseline total energy intake, particularly in the young. Future research is required to determine ways of decreasing energy intake in younger individuals.
