Objective TolearntheproteinintakestatusofadultsinZhejiangProvinceandtoinvestigatetherelationship between the protein intake and influencing factors,and in order to provide a scientific basis for improving adult protein intake.Methods Datawereselectedfromthe2010—2012ChineseNationalNutritionandHealthSurveyinZhejiang province.Data were gained through medical examination and the method of 3 day 24-hour dietary recall and food weighted record.Descriptiveanalysiswasconducted.Results Therewere1160men(48.09%)and1252women(51.91%)in 2 412 cases in this analysis.The average protein intake per day was 71.87 g for per reference man,and the intake quartile was 66.06(51.17-85.93)g/d and 38.14% of adults were not achieved the Recommended Nutrient Intake (RNI).The multi factor logistic regression analysis showed that age,region,income and occupation were the main factors affecting protein intake.Age was a risk factor,while income was a protective factor.Big cities were more easily to have insufficient protein intake than median and small cities.Students,agriculture,housework and other groups of adults were more easily to have insufficient protein intake.And 30.70% of dietary protein was from cereal,and 39.70% was from animal food. Sources of dietary protein were statistical significant among different areas and age.Protein intake from cereal among young people (29.60%),old people (29.95%),and people living in big cities (19.81%)was low.Protein intake from cereal among people living in medium and small cities (10.40%)was high.Young people (43.12%)and people living in big cities(52.87%)hadhigheranimalsourceprotein.Conclusion TheproteinintakeofadultsinZhejiangProvincewasnot achieved the RNI.It is important to conduct health educations according to the protein intake problems of different groups to improve their protein intake status.
ABSTRACT
Dietary pattern has been revealed to be associated with metabolic syndrome. However, the association was not well documented in Chinese due to the complexity of Chinese foods. We mainly assessed the dietary patterns and examined their effects on metabolic syndrome among Chinese adults. Four dietary patterns including 'Refined Grains & Vegetables' Pattern, 'Dairy & Eggs' Pattern, 'Organ Meat & Poultry' Pattern, and 'Coarse Grains & Beans' Pattern were extracted. 'Dairy & Eggs' Pattern was associated with a decreased odds of metabolic syndrome in women, and 'Coarse Grains & Beans' Pattern was associated with a decreased odds of hypertension in men. These results provided a scientific basis for future research and dietary guideline perfection.

Objective To understand the dietary intake of selenium and its influencing factors among rural and urban residents in Zhejiang province. Methods From 2010 to 2012,a total of 2,659 residents were selected from large urban sites,small-medium urban sites and rural sites in Zhejiang. Using 24 -hour dietary recall method,a 3 -day household dietary survey to analysis the dietary intake of selenium. Results The average daily dietary intake of selenium for residents aged 1-,4-,7 -,11 -,14 -,18 -,45 - and 60 - was 21. 96,26. 39,31. 62,35. 26,29. 39,41. 78,39. 12 and 38. 40 μg,respectively. According to formulation of Chinese Nutrition Society,the dietary selenium intake of 42. 56%juveniles and 52. 09% of adults was below the estimated average requirement( EAR). Significant statistical differences were found between normal group and insufficient dietary selenium intake group in terms of age,sex,region,level of education, per capita annual income,physical exercise and smoking status(all P<0. 01). Influencing factors of insufficient selenium intake were female(OR =1. 86,95%CI:1. 59 -2. 63),rural area( OR =1. 46,95%CI:1. 23 -1. 73),lower level of education(OR=0. 70,95%CI:0. 57 -0. 86)and lower income( OR =0. 72,95% CI:0. 60 -0. 88). Conclusion Influencing factors of dietary selenium intake are sex,region,level of education and per capita income. Dietary selenium supplement should be strengthened through a variety of ways,especially in target population.
