| 目的 采用修订中国膳食平衡指数（DBI-07）评价陕西省汉中地区农村居民膳食质量，并探讨其影响因素。方法 2010 年采用半定量食物频率问卷对汉中地区18～80 岁农村居民膳食进行横断面调查。采用DBI-07 相关指标评价膳食质量；应用多因素线性回归方法，分析影响摄入不足和摄入过量的影响因素。结果 共调查2 241人，其中65%以上被调查村民的谷薯类、调味品摄入量平均水平超过推荐量；动物性食物、蛋奶类和蔬菜水果存在明显摄入不足。人群平均负端分（DBI_LBS）和正端分（DBI_HBS）分别为24.83和5.70，中度摄入不足（25≤DBI_LBS≤36）和摄入过量（14≤DBI_HBS≤19）的比例分别为33.4%和51.0%。家庭人口数、文化程度、财富指数、参加体育锻炼、劳动强度和已戒烟是摄入不足的保护因素（P<0.05）；中等经济水平、饮酒（≥2 次/周）、男性、年龄和吸烟（>15 支/日）是摄入过量的危险因素（P<0.05）；家庭人口数和高中及以上学历是摄入过量的保护因素（P<0.05）。结论 陕西省汉中地区农村居民膳食结构不均衡，以摄入量不足为主，同时存在部分食物摄入过量，有必要在不同人群中开展有针对性的干预措施。 |

| Objective To evaluate the quality of diet among rural residents in Hanzhong,Shaanxi province and to investigate the relative factors. Methods A cross-sectional survey on dietary status together with a semi-quantitative food frequency questionnaire were conducted among rural residents aged between 18 and 80 in Hanzhong of Shaanxi,in 2010. Quality of diet was evaluated by using DBI-07 scoring and evaluating system. Linear regression models were developed to identify factors related to under or over intakes. Results 2 241 rural residents were under study. 65% of the residents'daily intake of grains,oil and salt exceeded the RNI while animal food,diary food,eggs,vegetables and fruits were under,to some extent. The average values of DBI_LBS and DBI_HBS were 24.83 and 5.70. The proportions of moderate under-intake （25≤DBI_LBS≤36） and moderate over-intake（14≤DBI_HBS≤19）were 33.4% and 51.0%. Factors as family number,education level,fortune index,physical activity,higher labor intensity seemed to be protective for dietary under intake （P<0.05）. Moderate fortune index,drinking alcohol（more than once a week）,being male,age and smoking status（>15 cigarettes per day）were risk factors for over-intake of diet（P<0.05）. Factors as larger family size and having had education above the levels senior school were significantly and negatively associated with the over-intake of diet（P<0.05）. Conclusion The main diet problem among the rural residents was related to under-intaken but over-intake did exist to some extents. Our study results called for specific intervention in improving the quality of diet among the residents in Hanzhong. |
