To evaluate the quality of diet among rural residents in Hanzhong, Shaanxi province and to investigate the relative factors.
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.
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).
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.
评估陕西省汉中市农村居民的饮食质量并调查相关因素。
2010年对陕西省汉中市18至80岁的农村居民进行了饮食状况横断面调查及半定量食物频率问卷调查。采用DBI - 07计分与评价系统评估饮食质量。建立线性回归模型以确定与摄入不足或过量相关的因素。
共研究2241名农村居民。65%居民的谷物、油和盐日摄入量超过推荐营养素摄入量（RNI），而动物性食物、奶制品、蛋类、蔬菜和水果摄入量在一定程度上不足。DBI_LBS和DBI_HBS的平均值分别为24.83和5.70。中度摄入不足（25≤DBI_LBS≤36）和中度摄入过量（14≤DBI_HBS≤19）的比例分别为33.4%和51.0%。家庭人口数、教育水平、财富指数、身体活动、较高劳动强度等因素似乎对饮食摄入不足有保护作用（P < 0.05）。中度财富指数、饮酒（每周超过一次）、男性、年龄和吸烟状况（每天>15支）是饮食摄入过量的危险因素（P < 0.05）。家庭规模较大和受过高中以上教育与饮食摄入过量显著负相关（P < 0.05）。
农村居民的主要饮食问题与摄入不足有关，但也存在一定程度的摄入过量情况。我们的研究结果呼吁针对改善汉中市居民饮食质量采取具体干预措施。
