【摘要】:目的了解廣州市中小學(xué)生的營養(yǎng)狀況及影響因素,為制訂學(xué)校衛(wèi)生工作策略提供科學(xué)依據(jù)。方法選取廣州市30所中小學(xué)校,按年齡段(7~18歲)分層整群抽取14 931名學(xué)生,測量其身高及體重,計(jì)算體質(zhì)量指數(shù)(body mass index,BMI),并進(jìn)行問卷調(diào)查。結(jié)果廣州市中小學(xué)生營養(yǎng)不良率為12.70%,鄉(xiāng)村學(xué)生(14.53%)高于城市(11.91%),男生(13.34%)高于女生(12.05%),差異均有統(tǒng)計(jì)學(xué)意義(χ~2值分別為19.47,5.62,P值均0.05)。學(xué)生超重率為9.58%,肥胖率為6.07%,超重率、肥胖率均為城市學(xué)生(10.48%,6.32%)高于鄉(xiāng)村學(xué)生(7.53%,5.50%);男生(12.32%,8.04%)高于女生(6.80%,4.08%),差異均有統(tǒng)計(jì)學(xué)意義(χ~2值分別為131.13,102.62,P值均0.05)。多因素Logistic回歸分析顯示,16~18歲、男生、鄉(xiāng)村學(xué)生、每周吃雞蛋次數(shù)3次、體育鍛煉時間1 h/d的中小學(xué)生營養(yǎng)不良風(fēng)險較高;調(diào)整年齡、城鄉(xiāng)、性別后,學(xué)校是否存在擠占體育課現(xiàn)象、學(xué)生上體育課的意愿、學(xué)生長跑的意愿是學(xué)生超重肥胖的影響因素(P值均0.05)。結(jié)論學(xué)生營養(yǎng)狀況存在城鄉(xiāng)差異,超重和肥胖所占比例較大。體育鍛煉的時間和主觀意愿對營養(yǎng)狀況影響較大。
