目的探讨中心性肥胖与膳食质量、身体活动之间的关系,确定中心性肥胖的干预重点。方法选用2010年中国居民营养与健康状况监测的198名18～60岁成年人膳食调查及体格检查资料,采用膳食平衡指数(DBI)评价方法评价天津城区不同腰围成人的膳食质量,统计其身体活动情况。结果不同腰围人群的大多数人的总体膳食结构都不平衡,摄入不足和摄入过量并存,食物种类摄入偏少,水果、奶类、豆类摄入量严重不足,畜禽肉和蛋类摄入过量。中心性肥胖成人平均活动时间少于正常腰围成人,而静坐时间高于正常腰围成人,主动锻炼率低于正常腰围成人,差异均有统计学意义(P<0.01,P<0.05)。结论在中心性肥胖者生活方式的影响因素中,活动量比膳食更为重要。
