摘要： 目的 分析2005-2014年10年间中国傈僳族儿童青少年体格生长发育和营养状况的发展变化趋势,并提出改善傈僳族儿童青少年目前生长发育和营养现状的建议。方法 采用多阶段分层随机整群抽样的方法,在云南省怒江州3个县随机抽取24所中小学7~18岁傈僳族学生作为研究对象。采用WHO-2006标准,对2005-2014年间历次参加全国学生体质健康调研的学生进行学生体格生长发育的变化趋势,以及生长迟缓和消瘦检出率的变化情况的比较。结果 2005-2014年傈僳族男、女生的营养不良率从48.84%和41.13%下降到30.96%和23.41%。其中 2005、2010年和2014年男生生长迟滞率分别为43.22%、35.54%和25.80%;女生分别为38.15%、33.56%和20.30%。2005、2010年和2014年傈僳族18岁身高性差分别为8.94 cm、9.96 cm和11.28 cm。结论 傈僳族儿童青少年营养状况得到明显改善,但学生营养不良问题仍很严重。针对学生营养不良和性差<13 cm等问题,建议开展人群的营养与健康教育干预工作,进一步加大力度推动和促进学生营养改善计划工作的开展,深度挖掘傈僳族成年身高的增长潜力。
