Abstract

OBJECTIVE

To document meal frequency and its relationship to body mass index (BMI) in a longitudinal sample of black and white girls from ages 9-19 years.

DESIGN

Ten-year longitudinal observational study.

SUBJECTS

At baseline, 1209 Black girls (539 age nine years, 670 age 10 years) and 1,166 White girls (616 age nine years, 550 age 10 years) were enrolled in the National Heart, Lung and Blood Institute Growth and Health Study (NGHS).

MEASUREMENTS

Three-day food diaries, measured height and weight and self-reported physical activity and television viewing were obtained at annual in-person visits.

RESULTS

Over the course of the study, the percentage of girls eating 3+ meals on all 3 days was reduced by over half (15 vs 6%). Participants who ate 3+ meals on more days had lower BMI-for-age z-scores. Black girls, but not white girls, who ate 3+ meals on more days were less likely to meet criteria for overweight.

CONCLUSION

Meal frequency was related to BMI and should be considered when developing guidelines to prevent childhood overweight.

摘要

目的

记录9至19岁黑人和白人女孩纵向样本中的进餐频率及其与体重指数(BMI)的关系。

设计

为期十年的纵向观察性研究。

对象

在基线时,1209名黑人女孩(539名9岁,670名10岁)和1166名白人女孩(616名9岁,550名10岁)参加了美国国立心肺血液研究所生长与健康研究(NGHS)。

测量

在每年的亲自访视中获取三天的食物日记、测量身高和体重以及自我报告的身体活动和看电视情况。

结果

在研究过程中,三天都吃三餐及以上的女孩比例减少了一半以上(15%对6%)。在更多天数吃三餐及以上的参与者年龄别BMI z评分较低。更多天数吃三餐及以上的黑人女孩,但不是白人女孩,达到超重标准的可能性较小。

结论

进餐频率与BMI有关,在制定预防儿童超重的指南时应予以考虑。
