背景1980年至2004年，美国儿童和青少年超重的患病率有所增加。目的评估3种高体重指数（BMI）的患病率，（计算方法为体重（公斤）除以身高（米）的平方），并使用测量身高和体重的全国数据来研究美国儿童和青少年的最新趋势。作为2003- 2004年和2005- 2006年国家健康和营养检查调查（NHANES）的一部分，从8165名儿童和青少年中获得身高和体重测量值，NHANES是美国平民的全国代表性调查，主要结果测量BMI在第97百分位数或以上，第95百分位数或以上，在2000年疾病控制和预防中心（CDC）按年龄，性别，结果由于2003- 2004年和2005- 2006年的估计值之间没有发现高BMI患病率的统计学显著差异，将这4年的数据合并，以提供最近时期的更稳定估计数。总体而言，2003- 2006年，（95%置信区间[ CI]，9.7%- 12.9%）的2 - 19岁儿童和青少年达到或超过2000年BMI-年龄生长图表的第97百分位数，16.3%（95% CI，14.5%- 18.1%）等于或高于第95百分位数，31.9%（95% CI，29.4%- 34.4%）等于或高于第85百分位数。患病率估计值因年龄和种族/族裔群体而异。对年龄相关高BMI趋势的分析显示，在4个时间段内，（1999- 2000年、2001- 2002年、2003- 2004年、（2005- 2006年）结论2003- 2010年儿童和青少年高BMI的患病率没有显著变化，2004年和2005- 2006年，1999年和2006年之间没有明显趋势。
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.
