Abstract

OBJECTIVE

To examine overweight trends over a 22-year period among preschool-aged children from primarily middle-income families enrolled in a health maintenance organization.

RESEARCH METHODS AND PROCEDURES

From well-child care visits to a Massachusetts health maintenance organization, we randomly selected one visit per child per calendar year, yielding a study sample of 120,680 children seen at 366,109 visits from 1980 through 2001. Using multivariate logistic regression models accounting for repeated observations of individual children across years, we estimated trends in prevalence of overweight (weight-for-length/height > or = 95th percentile) and at-risk-for-overweight (85th to 95th percentile).

RESULTS

Over the 22-year study period, the observed prevalence of overweight increased from 6.3% to 10.0% and at-risk-for-overweight increased from 11.1% to 14.4%. These increases were evident among all groups of children including infants < 6 months of age. Overall, the adjusted odds ratios were 1.21 per decade (95% confidence interval, 1.17 to 1.25) for overweight and 1.06 per decade (95% confidence interval, 1.03 to 1.08) for at-risk-for-overweight.

DISCUSSION

Rates of overweight are increasing in very young children, even infants, from primarily middle-class families.

摘要

目的

研究加入健康维护组织的主要来自中等收入家庭的学龄前儿童在22年期间的超重趋势。

研究方法与步骤

从马萨诸塞州一家健康维护组织的儿童健康检查就诊记录中，我们按日历年度为每个孩子随机选取一次就诊记录，从而得到一个研究样本，该样本涵盖了1980年至2001年期间在366,109次就诊中接受检查的120,680名儿童。我们使用多变量逻辑回归模型来考虑个体儿童多年的重复观察数据，估计超重（身长/身高体重比≥第95百分位数）和超重风险（第85至95百分位数）的患病率趋势。

结果

在这22年的研究期间，超重的观察患病率从6.3%上升至10.0%，超重风险患病率从11.1%上升至14.4%。在包括6个月以下婴儿在内的所有儿童群体中，这些增长都很明显。总体而言，超重的校正比值比为每十年1.21（95%置信区间，1.17至1.25），超重风险的校正比值比为每十年1.06（95%置信区间，1.03至1.08）。
