婴儿期喂养行为与4～5岁儿童单纯性肥胖症关系的研究

A study on association between infant feeding behavior and simple obesity in children aged 4～5 years old

目的 探讨婴儿期喂养行为与 4～ 5岁儿童单纯性肥胖症发生之间的关系。方法 对 180 0名 4～ 5岁儿童的婴儿期喂养情况及 4～ 5岁时BMI发育情况等进行调查 ,采用病例对照研究的方法分析婴儿 4个月内喂养类型、母乳喂养持续时间和辅食添加时间与 4～ 5岁儿童单纯性肥胖症发生之间的关系。结果 4个月内只喂母乳、主要喂母乳、母乳与配方奶量基本相同、主要喂配方奶、只喂配方奶者 4～ 5岁时肥胖发生率分别为 12 .63 %、13 .0 4%、16.98%、18.18%、3 0 .0 0 % ;母乳喂养持续时间 0 ,<1,1～ 3 ,4～ 6,7～ 9,9个月以上者 4～ 5岁时肥胖发生率分别为 2 9.41%、3 0 .0 0 %、3 3 .3 3 %、17.2 4%、13 .92 %、12 .2 2 % ;辅食添加时间 4个月内 ,4～ 6个月 ,6个月以上者 4～ 5岁时肥胖发生率分别为 15 .0 9%、11.5 6%、18.85 %。喂养类型不同、母乳持续时间不同及辅食添加时间不同的儿童 4～ 5岁时单纯性肥胖症发生率不同 (χ2 =10 .40 7,P <0 .0 5 ;χ2 =2 0 .90 3 ,P <0 .0 0 1;χ2 =13 .0 92 ,P <0 .0 1)。多因素logis tic回归分析发现 4个月内喂配方奶量越多 ,肥胖发生率越高 (OR =1.12 0 ) ;母乳喂养持续时间越长 ,肥胖发生越少 (OR =0 .782 ) ;辅食添加越早 ,肥胖发生越多 (OR =0 .92 3 )。结论 婴儿母?

Objective To elucidate the association between infant feeding behavior and simple obesity in children aged 4～5 years old. Methods 1800 children aged 4～5 years old were chosen. Their feeding and BMI development were investigated. Association between infant feeding and simple obesity in preschool children were analyzed. Results The occurrence rates of simple obesity in preschool children whose feeding types in first 4 months were breast milk only, more breast milk than infant formula, both equally, more infant formula than breast milk, infant formula only were separately 12.63%, 13.04%, 16.98%, 18.18%, 30.00%. The occurrence rates of simple obesity in preschool children whose breastfeeding duration were 0,<1,1～3,4～6,7～9,>9months were separately 29.41%, 30.00%, 33.33%, 17.24%, 13.92%, 12.22%. The occurrence rates of simple obesity in preschool children whose timing introduction of solid foods were <4,4～6,> 6months were separately 15.09%, 11.56%, 18.85%.The occurrence rates of simple obesity in preschool children are different among various breastfeeding type , different duration or different timing introduction of solid foods in single factor analysis(χ 2=10.407, P <0.05;χ 2=20.903, P <0.001;χ 2=13.092, P <0.01). After adjusting for potential confounders , multiple factors logistic regression analysis showed that the more formula milk was given during the first 4 months after birth the more obesity in the preschool children occurred(OR=1.120), the longer duration of breastfeeding the less occurrence of obesity in preschool children(OR=0.782).The earlier timing introduction of solid foods the more obesity in the preschool children occurred(OR=0.923). Conclusions Infants who were fed breast milk more than infant formula, or who were breasted for longer periods, had a lower risk of being simple obesity during preschool children. Breastfeeding should be strongly recommended and lasted for more than 9 months. Too early introduction of solid foods may increase the occurrence rate of simple obesity in preschool children.
