ABSTRACT
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.
