【摘要】：目的使用中國(guó)家庭追蹤調(diào)查數(shù)據(jù)探究中國(guó)母乳喂養(yǎng)與兒童體質(zhì)指數(shù)(BMI)、超重及肥胖關(guān)系,判定母乳喂養(yǎng)能否預(yù)防兒童肥胖,為制訂兒童肥胖防治策略提供科學(xué)依據(jù)。方法收集2 388名5歲兒童的相關(guān)資料,對(duì)母乳喂養(yǎng)的持續(xù)時(shí)間二分為有與沒(méi)有、≥6個(gè)月與6個(gè)月、≥8個(gè)月與8個(gè)月和≥12個(gè)月與12個(gè)月;對(duì)每一種二分法采用logistic回歸分析計(jì)算傾向評(píng)分,比較BMI與母乳喂養(yǎng)狀況差異是否有統(tǒng)計(jì)學(xué)意義,在較高BMI百分位的兒童中結(jié)合分位數(shù)回歸進(jìn)行判斷。結(jié)果在調(diào)整傾向得分后,并未發(fā)現(xiàn)母乳喂養(yǎng)對(duì)減少體重有任何顯著的影響,相反,長(zhǎng)時(shí)間的母乳喂養(yǎng)可以增加肥胖的風(fēng)險(xiǎn)(OR=1.42,95%CI=1.07~1.89,P=0.02);分位數(shù)回歸顯示,母乳喂養(yǎng)在擁有極端BMI的兒童中未發(fā)揮有益作用。結(jié)論母乳喂養(yǎng)在降低BMI或兒童超重和肥胖的風(fēng)險(xiǎn)方面未發(fā)現(xiàn)明顯的保護(hù)作用。
[Abstract]:Objective to explore the relationship between Chinese breast feeding and overweight and obesity of children with body mass index (BMI),) by using Chinese family tracing data, and to determine whether breastfeeding can prevent obesity in children, and to provide scientific basis for formulating strategies for prevention and treatment of childhood obesity. Methods the data of 2 388 children aged 5 years were collected. The duration of breast feeding was divided into two groups: 6 months and 6 months, 鈮，
