目的比较辽宁、广东两省7~12岁儿童肥胖、腹型肥胖患病率,为防制儿童肥胖提供相关依据。方法采用整群随机抽样的方法,于2013年共抽取7~12岁的儿童10 179名(辽宁省5 569名,广东省4 610名),以年龄别、性别体质量指数(BMI)和腰围分别作为划分营养不良、超重、肥胖和腹型肥胖的标准,采用协方差分析、χ2检验比较两省的差异。结果调整性别和年龄后,辽宁省7~12岁儿童的身高(141.23 cm)、体重(37.15 kg)、腰围(62.51 cm)、臀围(73.80 cm)和BMI(18.16 kg/m2)均高于广东省(140.40 cm,34.74 kg,61.95 cm,71.56 cm,17.19 kg/m2)(P值均<0.05);辽宁省7~12岁儿童的营养不良率、超重率、肥胖率和腹型肥胖率分别为7.5%,13.6%,16.0%和23.2%;广东省为14.1%,11.6%,9.9%和20.3%,两省差异均有统计学意义(P值均<0.05)。根据BMI进行分层后,广东省各组儿童的腰围均值均高于辽宁省,正常和超重组腹型肥胖率也高于辽宁省(P值均<0.05)。结论辽宁和广东省的儿童肥胖、腹型肥胖高度流行,广东省的情况虽较辽宁省乐观,但是腹型肥胖的问题也不容忽视,应采取相关措施进行控制。
Objective To compare the prevalence of obesity and abdominal obesity in children aged 7 ~ 12 in Liaoning and Guangdong provinces and to provide relevant evidence for the prevention of childhood obesity. Methods A total of 10 179 children (5 569 in Liaoning province and 4 610 in Guangdong province) were enrolled in this study. A total of 10 179 children aged 7-12 years were enrolled in this study. The age, sex, body mass index (BMI) and waist circumference As the standard to divide malnutrition, overweight, obesity and abdominal obesity, covariance analysis and χ2 test were used to compare the differences between the two provinces. Results After adjusting for sex and age, the height (141.23 cm), body weight (37.15 kg), waist circumference (62.51 cm), hip circumference (73.80 cm) and BMI (18.16 kg / m2) The incidences of malnutrition, overweight, obesity and abdominal obesity in children aged 7-12 years in Liaoning province were significantly higher than those in Guangdong province (P <0.05) Respectively, which were 7.5%, 13.6%, 16.0% and 23.2% respectively; Guangdong Province was 14.1%, 11.6%, 9.9% and 20.3% respectively. There was significant difference between the two provinces (all P <0.05). According to the BMI stratification, the average waist circumference of children in each group in Guangdong Province was higher than that in Liaoning Province. The obesity rate in normal and overweight group was also higher than that in Liaoning Province (P <0.05). Conclusion Children obesity and abdominal obesity are highly prevalent in Liaoning and Guangdong Provinces. Although the situation in Guangdong Province is more optimistic than that in Liaoning Province, the problem of abdominal obesity should not be overlooked. Relevant measures should be taken to control it.
