Abstract ObjectiveTo learn the protein intake status of adults in Zhejiang Province and to investigate the relationship between the protein intake and influencing factors, and in order to provide a scientific basis for improving adult protein intake. MethodsData were selected from the 2010—2012 Chinese National Nutrition and Health Survey in Zhejiang province. Data were gained through medical examination and the method of 3 day 24-hour dietary recall and food weighted record. Descriptive analysis was conducted. ResultsThere were 1 160 men (48.09%) and 1 252 women (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%) had higher animal source protein. ConclusionThe protein intake of adults in Zhejiang Province was not 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.
