OBJECTIVES
We examined recent overweight and obesity trends in a multiethnic population of low-income preschool children.
METHODS
We defined overweight as sex-specific body mass index (BMI)-forage > or = 85th and < 95th percentile and obesity as sex-specific BMI-for-age > or = 95th percentile, and calculated them using demographic data and randomly selected height and weight measurements that were recorded while 2- to < 5-year-old children were enrolled in the New York State (NYS) Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) during 2002-2007.
RESULTS
Obesity prevalence peaked at 16.7% in 2003, declined from 2003 through 2005, and stabilized at 14.7% through 2007. Among both boys and girls, the downward trend in annual prevalence of obesity was evident only among Hispanic children (22.8% boys and 20.9% girls in 2002 vs. 19.3% boys and 17.5% girls in 2007) and non-Hispanic black children (15.6% boys and 14.2% girls in 2002 vs. 13.6% boys and 12.4% girls in 2007). In contrast, the annual prevalence estimate for overweight showed an increasing trend from 2002 through 2007.
CONCLUSIONS
These results showed a slight decline in prevalence of childhood obesity and a continuing rise in prevalence of childhood overweight among children enrolled in the NYS WIC program during 2002-2007. Future research should investigate the extent to which the slight decline in childhood obesity prevalence may be attributable to population-based and high-risk obesity prevention efforts in NYS.
目的
我们研究了低收入学龄前儿童多民族人群中最近超重和肥胖的趋势。
方法
我们将超重定义为特定性别的体重指数（BMI）-年龄>或=第 85 百分位和<第 95 百分位，肥胖定义为特定性别的 BMI-年龄>或=第 95 百分位，并使用人口统计数据和随机选择的身高和体重测量值计算，这些数据是在 2002-2007 年期间，2 至<5 岁的儿童参加纽约州（NYS）妇女、婴儿和儿童特别补充营养计划（WIC）时记录的。
结果
肥胖患病率在 2003 年达到 16.7%的峰值，从 2003 年到 2005 年下降，到 2007 年稳定在 14.7%。在男孩和女孩中，肥胖的年患病率呈下降趋势，这一趋势仅在西班牙裔儿童（2002 年男孩为 22.8%，女孩为 20.9%，2007 年男孩为 19.3%，女孩为 17.5%）和非西班牙裔黑儿童（2002 年男孩为 15.6%，女孩为 14.2%，2007 年男孩为 13.6%，女孩为 12.4%）中明显。相比之下，超重的年患病率估计从 2002 年到 2007 年呈上升趋势。
结论
这些结果表明，在 2002-2007 年期间，参加纽约州 WIC 计划的儿童肥胖患病率略有下降，而儿童超重患病率持续上升。未来的研究应调查纽约州基于人群的和高危肥胖预防工作在多大程度上可能导致儿童肥胖患病率的轻微下降。
