Abstract Objective To learn the results of MNA ( mini nutritional assessment ） nutrition screening and influencing factors in the elderly living at home, so as to provide basis for improving the nutritional status of the elderly living at home. Methods The elderly people at home were recruited from Yinzhou District, Yiwu City and Changshan County in Zhejiang Province by the multi-stage random sampling method. Their demographic information, living habits and nutritional status were collected by the MNA scale and the questionnaire for nutrition and health status surveillance. The multivariate linear regression model was used to analyze influencing factors for the nutritional status. Results Of 374 study subjects, 186 ( 49.73% ) were males and 188 ( 50.27% ) were females. The age was ( 69.63±6.68 ) years ( range, 60-90 years ). The average score of MNA scale was 25.26±2.81. The prevalence of malnutrition risk in the elderly living at home was 20.59%. Age ( β'=-0.140), marital status ( β'=0.110 ), annual income ( β'=0.155 ), active physical exercise ( β'= 0.104 ), eating health products/nutritional supplements ( β'= 0.110 ) and satiety ( full diet β'=0.196 ) were influencing factors for MNA scores ( P<0.05 ）. Conclusion The prevalence of malnutrition risk among the elderly living at home is 20.59%. The prevalence increases with age. Having a spouse, doing active physical exercise, eating health products/nutritional supplements, having healthy eating habits are conducive to maintaining the nutritional health of the elderly.
