浙江省居民膳食结构与质量评价

目的评价浙江省18－79岁居民的膳食结构及膳食质量,为干预措施提供依据。方法选取2010—2012年＂中国居民营养状况监测项目＂中浙江省6个市18－79岁居民的膳食调查资料,利用中国膳食平衡指数评价居民的膳食结构及膳食质量。结果浙江省居民的膳食质量多处于轻度（41.08%）到中度（50.79%）的膳食失衡,摄入不足与摄入过量并存,其中轻度和中度摄入不足分别占66.17%和27.88%,轻度膳食过量占35.55%;膳食平衡指数DBI-LBS、DBI-HBS和DBI-DQD分别为46.00、26.00和57.00;摄入过量及膳食失衡在人群中的分布特点为：男性高于女性,农村高于城市,40－49岁者最高,摄入不足与膳食失衡随着文化程度的增高而降低（P〈0.05）;浙江省居民的主要膳食模式为模式B,为62.41%;其次为模式A,为26.44%。结论浙江省居民的膳食中,摄入不足与摄入过量并存,呈现一定程度的膳食失衡,男性、40－49岁、农村地区及文化程度低的居民为重点干预人群。

An evaluation on dietary pattern and quality among residents in Zhejiang province

Methods 2152 residents aged 18- 79 years old were selected using multi- stage stratified cluster random sampling method and the data from Chinese nutrition status monitoring project during 2010- 2012 was used. The results were evaluated using Chinese diet balance index. Results 41. 08% of the residents in Zhejiang province was mild diet imbalance and 50. 79% was middle diet imbalance while insufficient and excessive intakes were coexist. Mild and middle insufficient intakes were accounted for 66. 17% and 27. 88% respectively,while mild excessive intake was accounted for 35. 55%. The diet balance indexes including DBI- LBS,DBI- HBS and DBI- DQD were 46. 00,26. 00 and 57. 00 respectively. The dietary quality of males,rural areas was lower while residents aged 40- 49 years had the lowest dietary quality. There was positive correlation between dietary quality and degree of education（ P〈 0.05）. The main dietary pattern of residents in Zhejiang was pattern B（ 62. 41%） following by pattern A（ 26. 44%）. Conclusion Insufficient and excessive intakes coexist among residents in Zhejiang province.
