在美国儿童肥胖患病率增加几十年后，最近的研究结果表明，某些人群的患病率已经持平或正在下降。然而，人口统计学和社会经济学的差异仍然存在，并可能会增加。MethodsTo评估最近的趋势和差异，儿童肥胖患病率在洛杉矶县，我们分析了数据，从2001年到2013年在五年级学生在洛杉矶联合学区（LAUSD）。肥胖的定义是，根据测量的身高和体重，与疾病控制和预防中心的生长图表相比，相同年龄和性别的儿童的体重指数等于或高于第95百分位数。按性别、种族/民族和社会经济地位（SES）检查趋势。SES是通过使用学校一级的数据，学生参加免费和降价meaningprograms.Resultsobesity患病率从2001年的27.5%增加到2005年的31.6%，是稳定的，从2005年到2010年，并从2010年的31.6%下降到2013年的28.5%。在所有人口统计学和社会经济地位亚组中观察到类似的患病率轨迹，尽管白人和在社会经济地位最高的学校上学的学生中患病率的下降开始得更早。在整个研究期间，观察到不同种族/民族和SES的患病率差异，但从2010年到2013年略有缩小。结论虽然LAUSD五年级学生的肥胖患病率从2010年到2013年有所下降，但患病率仍高于2001年，患病率的人口统计学和社会经济学差异持续存在。该县未来的干预措施应优先考虑拉丁美洲人和就读社会经济地位较低学校的学生。
IntroductionAfter multiple decades of increasing childhood obesity prevalence in the United States, findings from recent studies suggest that prevalence has leveled or is decreasing in some populations. However, demographic and socioeconomic disparities in prevalence remain and may be increasing.MethodsTo assess recent trends and disparities in childhood obesity prevalence in Los Angeles County, we analyzed data from 2001 through 2013 in fifth graders in the Los Angeles Unified School District (LAUSD). Obesity was defined as a body mass index at or above the 95th percentile for children of the same age and sex as compared with Centers for Disease Control and Prevention growth charts, on the basis of measured height and weight. Trends were examined by sex, race/ethnicity, and socioeconomic status (SES). SES was determined by using school-level data on the percentage of students participating in a free and reduced-price meal program.ResultsObesity prevalence increased from 27.5% in 2001 to 31.6% in 2005, was stable from 2005 through 2010, and decreased from 31.6% in 2010 to 28.5% in 2013. Similar trajectories in prevalence were observed for all demographic and SES subgroups, although the decline in prevalence began earlier among whites and students attending schools in the highest SES group. Disparities in prevalence by race/ethnicity and SES were observed during the entire study period but narrowed slightly from 2010 through 2013.ConclusionAlthough obesity prevalence among fifth graders in LAUSD declined from 2010 through 2013, prevalence remains higher than in 2001, and demographic and socioeconomic disparities in prevalence persist. Future interventions in the county should prioritize Latinos and students attending low SES schools.
