To analyze the status of overweight and obesity among preschool children in rural areas of ten provinces in China.
Using data from "Physical development of rural children under the age of 7 from ten provinces of China in 2006", preschool children were selected as the object of study. Overweight, mild obesity, moderately obese, severe obesity were defined as:weight was over 10%, 20%, 30%, 50% than the same sex under height population reference mean. SPSS 13.0 software was used for statistical analysis. χ² test was used to compare rates.
A total number of 38 923 preschool children were included in the study. The overall prevalence of overweight was 4.18%, with boy's higher than girl's (χ² = 4.343 6, P = 0.037 1) and the highest rate of overweight (5.80%) was seen in the 3-year-old group. The overall prevalence of obesity was 1.21% , with majority as mild (0.78%). There was no significant difference between boys and girls (χ² = 0.389 0, P = 0.532 8). The 6 to 7 year old group had the highest rate of obesity (1.42%). In the ten provinces, the prevalence rates of overweight were 1.38%-7.62% and the obesity were 0.57%-3.08% . The prevalence rates of overweight and obesity showed the highest in Jilin and lowest in Guangxi.
The overall prevalence rates of overweight and obesity among preschool children in rural areas of China were low, with 3 to 4-year-olds appeared in the age of high incidence of overweight and obesity. The overall prevalence rates of overweight and obesity in northern area were higher than in other areas.
分析我国十省农村地区学龄前儿童超重与肥胖状况。
采用“2006年中国十省农村7岁以下儿童体格发育调查”数据，选取学龄前儿童作为研究对象。超重、轻度肥胖、中度肥胖、重度肥胖的定义为：体重超过同性别同身高人群参考均值的10%、20%、30%、50%。应用SPSS 13.0软件进行统计分析，采用χ²检验比较率的差异。
共纳入38923名学龄前儿童。超重总体患病率为4.18%，男孩高于女孩（χ² = 4.343 6，P = 0.037 1），超重率最高的是3岁组（5.80%）。肥胖总体患病率为1.21%，以轻度肥胖为主（0.78%）。男孩与女孩之间差异无统计学意义（χ² = 0.389 0，P = 0.532 8）。6至7岁组肥胖率最高（1.42%）。在十省中，超重患病率为1.38% - 7.62%，肥胖患病率为0.57% - 3.08%。超重与肥胖患病率以吉林最高，广西最低。
我国农村地区学龄前儿童超重与肥胖总体患病率较低，3至4岁为超重与肥胖高发年龄段。北方地区超重与肥胖总体患病率高于其他地区。
