RESUMEN
Objective To understand the dairy product intake in residents of Shanghai,its seasonal changes and the influencing factors.Methods A group of representative residents was surveyed and followed up in four seasons in Shanghai during 2012-2014.Information of the dairy product intake was collected by food frequency questionnaire.Results Liquid milk and yogurt were the main dairy products consumed by the residents of Shanghai.The annual dairy product intake rate was 41.8％,and the median of dairy intake of milk was 145.3 g/d,accounting for 48.4％ of reference dietary intake value,and only 4.5％ of people's diary product intake reached intake reference value.The area specific differences in intake rate of liquid milk,yogurt and total dairy product intake were significant in four seasons and in whole year (P＜0.05).The area specific differences in total dairy product intake were significant (P＜0.05) in spring,summer and winter.In general,it was shown that dairy product intake in urban area was higher than that in suburban area and in rural area.The data of Shanghai and urban area showed that the total dairy product intake was significant different among four seasons (P＜0.05),but no significant difference was observed among four seasons in suburban and rural areas.The logistic regression analysis results showed that people with average household income higher than local average level or higher education levels were more likely to consume dairy products daily.People who reported to have good health status or sleep quality were more likely to drink milk compared to those who have worse health status or sleep quality (P＜0.05).Conclusions Even though dairy product intake rate and volume have been improved in residents in Shanghai,it is still stay at lower level,especially in rural area.To promote consumption of dairy products,it is necessary to control diary product price from macro perspective,and strengthen healthy education about the importance of dairy product intake and guide residents to select suitable dairy products.
RESUMEN
Objective: To understand the dairy product intake in residents of Shanghai, its seasonal changes and the influencing factors. Methods: A group of representative residents was surveyed and followed up in four seasons in Shanghai during 2012-2014. Information of the dairy product intake was collected by food frequency questionnaire. Results: Liquid milk and yogurt were the main dairy products consumed by the residents of Shanghai. The annual dairy product intake rate was 41.8%, and the median of dairy intake of milk was 145.3 g/d, accounting for 48.4% of reference dietary intake value, and only 4.5% of people's diary product intake reached intake reference value. The area specific differences in intake rate of liquid milk, yogurt and total dairy product intake were significant in four seasons and in whole year (P<0.05). The area specific differences in total dairy product intake were significant (P<0.05) in spring, summer and winter. In general, it was shown that dairy product intake in urban area was higher than that in suburban area and in rural area. The data of Shanghai and urban area showed that the total dairy product intake was significant different among four seasons (P<0.05), but no significant difference was observed among four seasons in suburban and rural areas. The logistic regression analysis results showed that people with average household income higher than local average level or higher education levels were more likely to consume dairy products daily. People who reported to have good health status or sleep quality were more likely to drink milk compared to those who have worse health status or sleep quality (P<0.05). Conclusions: Even though dairy product intake rate and volume have been improved in residents in Shanghai, it is still stay at lower level, especially in rural area. To promote consumption of dairy products, it is necessary to control diary product price from macro perspective, and strengthen healthy education about the importance of dairy product intake and guide residents to select suitable dairy products.
