目的了解河北省邢台市学龄前幼儿单纯性肥胖与出生体重的关系。方法采取整群抽样的方法,对邢台市12所幼儿园3~6岁幼儿的父母进行问卷调查,同时对3~6岁的幼儿进行身高体重测定。根据WHO推荐的身高体重标准进行肥胖的判定。结果在2 676名3~6岁学龄前幼儿中,肥胖率7.59%。其中,男性幼儿1 369人,肥胖率8.06%;女性幼儿1 287人,肥胖率7.07%。男性幼儿与女性幼儿单纯性肥胖率的差异无统计学意义(χ~2=0.94,P>0.05)。在296名巨大出生体重儿中,肥胖率15.20%;在2 261名正常体重出生儿中,肥胖率6.46%;在119名低出生体重儿中,肥胖率10.08%。巨大出生体重儿肥胖率明显高于出生体重正常儿,差异有统计学意义(χ~2=28.96,P<0.01)。巨大出生体重儿的肥胖率与低出生体重儿的肥胖率的差异无统计学意义(χ~2=1.88,P>0.05)。低出生体重儿肥胖率与正常体重出生儿肥胖率的差异无统计学意义(χ~2=2.40,P>0.05)。结论河北省邢台市学龄前幼儿肥胖率水平较高,尤其是巨大出生体重儿的幼儿单纯性肥胖率高于低出生体重儿与正常体重出生儿肥胖率。 Objective To understand the relationship between simple obesity and birth weight in preschool children in Xingtai City of Hebei Province. Methods The method of cluster sampling was used to survey the parents of 3 to 6 years old children in 12 kindergartens in Xingtai City. At the same time, the height and weight of 3 to 6 years old children were measured. According to WHO recommended height and weight standards for obesity. Results Among 2 676 preschool children aged 3 ~ 6, the obesity rate was 7.59%. Among them, there are 1 369 young toddlers, with an obesity rate of 8.06%; and 1 287 toddler children with a obesity rate of 7.07%. There was no significant difference in simple obesity rate between young male and female children (χ ~ 2 = 0.94, P> 0.05). The obesity rate was 15.20% among 296 huge birth weight children; the obesity rate was 6.46% among 2,261 normal-born children and the obesity rate was 10.08% among 119 low birth weight children. The obesity rate of huge birth weight children was significantly higher than that of normal birth weight, the difference was statistically significant (χ ~ 2 = 28.96, P <0.01). There was no significant difference in the obesity rates between the children with huge birth weight and those with low birth weight (χ ~ 2 = 1.88, P> 0.05). There was no significant difference in obesity rate between low birth weight children and normal birth weight children (χ ~ 2 = 2.40, P> 0.05). Conclusion The prevalence of obesity among pre-school children in Xingtai City of Hebei Province is relatively high. Especially, the rate of obesity in young children with huge birth weight is higher than that of birth weight in low birth weight children and normal weight children.
