摘要
Abstract
[Objective] To analyze the relationship between iron overload and dietary nutrition and lifestyle in middle aged and elderly population,and to provide a reference for further study of the effects of iron overload on population health and disease prevention.[Method]A total of 120 iron overloaded people and 183 normal subjects with iron nutritional status were examined by case-control study.The survey included the basic situation,lifestyle and dietary structure.Analysis of influencing factors of iron overload by logistic regression.[Result] The proportion of smokers (30.0％),drinkers (52.5％) and people like eating red meat (27.5％) was significantly higher than that of the control group (15.8％,33.3％,14.8％),but the proportion of tea drinkers (54.2％) and exercise (47.5％) were significantly lower than those in the control group (65.5％ and 66.7％),the difference was statistically significant (P ＜ 0.05).By comparing the two groups of eating habits found that the frequency of eating meat in the case group was higher than the control group (Z =3.500,P ＜ 0.001),but the frequency of eating grains,potatoes,beans,milk,eggs,vegetables and fruits were lower than those of the control group (Z values were 3.911,2.664,3.255,2.335,2.089,5.791 and 6.689,respectively,P ＜0.05).Multivariate logistic regression indicated that smoking (OR=2.040,95％ CI:1.057 to3.935) and Eat meat every day (OR=2.473,95％ CI:1.368～4.469) were independent risk factor for iron overload.Eat vegetables every day (OR =0.240,95％ CI:0.115 ～0.500) and eat fruit every day (OR =0.448,95％ CI:0.245 ～0.819) were independent protection factor for iron overload.[Conclusion] Iron overload is closely related to dietary nutrition and lifestyle in middle aged and elderly population.The elderly population should be regular health check and take exercise to form a good life eating habits.关键词
