应用中国膳食平衡指数评价中国18～59岁人群的膳食质量

目的利用中国膳食平衡指数(DBI)综合评价中国成年人的膳食质量,验证DBI的有效性。方法选用2002年中国居民营养与健康状况调查28320名18～59岁成年人膳食调查及个人基本情况调查资料,采用DBI的评分及评价方法评价我国居民的膳食质量。结果目前中国人群的膳食状况仍以摄入不足为主要问题,同时也存在着食物摄入过量的问题。城乡间人群的膳食质量存在着一定的差异,农村居民无论是摄入不足还是摄入过量的程度都大于城市,显示出农村居民膳食失衡的程度较为严重。文化程度和经济收入也是影响居民膳食质量的主要因素。结论采用DBI评价人群的膳食质量,能够更好地描述人群膳食质量的总体概况,易于发现存在的主要问题,量化膳食中问题的程度,利于人群间的比较。
