Abstract

CONTEXT

The prevalence of overweight among US children and adolescents increased between 1980 and 2004.

OBJECTIVES

To estimate the prevalence of 3 measures of high body mass index (BMI) for age (calculated as weight in kilograms divided by height in meters squared) and to examine recent trends for US children and adolescents using national data with measured heights and weights.

DESIGN, SETTING, AND PARTICIPANTS: Height and weight measurements were obtained from 8165 children and adolescents as part of the 2003-2004 and 2005-2006 National Health and Nutrition Examination Survey (NHANES), nationally representative surveys of the US civilian, noninstitutionalized population.

MAIN OUTCOME MEASURES

Prevalence of BMI for age at or above the 97th percentile, at or above the 95th percentile, and at or above the 85th percentile of the 2000 sex-specific Centers for Disease Control and Prevention (CDC) BMI-for-age growth charts among US children by age, sex, and racial/ethnic group.

RESULTS

Because no statistically significant differences in the prevalence of high BMI for age were found between estimates for 2003-2004 and 2005-2006, data for the 4 years were combined to provide more stable estimates for the most recent time period. Overall, in 2003-2006, 11.3% (95% confidence interval [CI], 9.7%-12.9%) of children and adolescents aged 2 through 19 years were at or above the 97th percentile of the 2000 BMI-for-age growth charts, 16.3% (95% CI, 14.5%-18.1%) were at or above the 95th percentile, and 31.9% (95% CI, 29.4%-34.4%) were at or above the 85th percentile. Prevalence estimates varied by age and by racial/ethnic group. Analyses of the trends in high BMI for age showed no statistically significant trend over the 4 time periods (1999-2000, 2001-2002, 2003-2004, and 2005-2006) for either boys or girls (P values between .07 and .41).

CONCLUSION

The prevalence of high BMI for age among children and adolescents showed no significant changes between 2003-2004 and 2005-2006 and no significant trends between 1999 and 2006.

摘要

背景

1980年至2004年间，美国儿童和青少年超重的患病率有所上升。

目的

估计年龄别高体重指数（BMI，计算方法为体重千克数除以身高米数的平方）的三项指标的患病率，并利用全国性的身高和体重测量数据研究美国儿童和青少年的近期趋势。

设计、地点和参与者：作为2003 - 2004年和2005 - 2006年国家健康与营养检查调查（NHANES）的一部分，从8165名儿童和青少年中获取了身高和体重测量数据，NHANES是对美国平民非机构化人口具有全国代表性的调查。

主要结局指标

按年龄、性别和种族/族裔群体划分，美国儿童中年龄别BMI处于或高于2000年美国疾病控制与预防中心（CDC）特定性别的年龄别BMI生长图表第97百分位、第95百分位和第85百分位的患病率。

结果

由于在2003 - 2004年和2005 - 2006年的估计值之间，未发现年龄别高BMI患病率存在统计学显著差异，因此将这4年的数据合并，以提供最近时间段更稳定的估计值。总体而言，在2003 - 2006年，2至19岁的儿童和青少年中，11.3%（95%置信区间[CI]，9.7% - 12.9%）处于或高于2000年年龄别BMI生长图表的第97百分位，16.3%（95% CI，14.5% - 18.1%）处于或高于第95百分位，31.9%（95% CI，29.4% - 34.4%）处于或高于第85百分位。患病率估计值因年龄和种族/族裔群体而异。对年龄别高BMI趋势的分析显示，在4个时间段（1999 - 2000年、2001 - 2002年、2003 - 2004年和2005 - 2006年）中，男孩或女孩均未出现统计学显著趋势（P值在0.07至0.41之间）。
