| 目的 了解重庆市婴幼儿体质指数(body mass index, BMI)分布情况,探讨高BMI相关因素。 方法 选取2010年1月1日至2014年11月1日期间在重庆医科大学附属儿童医院儿童保健科进行体质量、身长等保健检查的7个月至2岁婴幼儿共31 902例(男童17 511例,女童14 391例)为研究对象,并记录社会人口统计学、出生情况及喂养情况等信息,采用χ2检验、Pearson相关分析及多因素logistic回归模型进行分析。 结果 7个月至2岁婴幼儿高BMI检出率为16.1%,男、女童分别为18.1%(3 175/17 511)和13.5%(1 948/14 391),男童检出率高于女童(P<0.01)。市区、巨大儿、剖宫产、父母文化程度高、部分母乳喂养婴幼儿高BMI的检出率较高,差异均有统计学意义(P<0.01)。多因素logistic回归模型分析显示,年龄、性别、地区、出生体质量、分娩方式、胎龄以及父母文化程度与高BMI有关(P<0.01)。 结论 出生体质量、分娩方式、年龄、性别、胎龄、父母文化程度以及地区是婴幼儿高BMI状态的相关因素,预防儿童肥胖应从多方面控制。 |

| Abstract: |
| Objective To investigate the body mass index (BMI) distribution of infants in urban Chongqing, and to explore the related factors of high BMI status. Methods A total of 31 902 (17 511 boys and 14 391 girls) infants aged from seven months to two years old, who received child heath care in Department of Child Health Care, the Children's Hospital of Chongqing Medical University from January 1st, 2010 to November 1st, 2014 were participants. The body mass, length, social demography, birth and infant feeding information were all collected. Chi-square test, Pearson correlation and logistic regression models were used for statistical analysis. Results The rate of high BMI status was 16.1% in infants aged seven months to two years old in our study, with the number of boys being significantly more than that of the girls (18.1% vs 13.5%, P<0.01). High BMI status in infants were associated with urban living, macrosomia, caesarean, high education level of parents and breast feeding (P<0.01). The multiple logistic regressions showed that age, gender, region of living, birth mass, delivery mode,gestational age and parents' education level were associated with high BMI status in infants aged from seven months to two years old (P<0.01) . Conclusion Birth mass, feeding patterns, age, gender and region are important factors for high BMI status in infants. Childhood obesity prevention should be prevented from many aspects. |
