ABSTRACT
Objective@#To investigate the comprehensive nutritional status and diet behavior of middle aged and elderly women with osteoporosis, and thereby to explore the relationship between diet behavior and comprehensive nutritional status.@*Methods@#311 middle-aged and elderly women with osteoporosis in Chengdu were included in this study. Mini Nutritional Assessment (MNA) was applied to assess their comprehensive nutritional status. Information of social-demographic characteristics and diet behavior (about meals, snacks and water drinking, etc.) of the subjects was collected by questionnaire. Chi square test was used to assess the differences in nutritional status among patients who have different eating behaviors. Logistic regression analysis was performed to evaluate the relationship between diet behaviors and comprehensive nutritional status.@*Results@#The mean MNA score of subjects was 25.8±2.5. 20.3% (63/311) of the subjets were at risk of potential malnutrition, but there was no malnourished subjects found. 46.9% (46/311) of the subjects were in good appetite. 95.2% (296/311) of them had a fixed food intake each meal. 65.8% (198/311) of them had snacks every day, and the most common choice was fruit (86.4% (248/287)). 54.8% (165/311) of them had initiative drinking water habits, and the most common choice was plain boiled water (79.9%, 246/308). 76.5% (238/311) of them had daily portable water less than 1 500 ml. After adjusting the effects of age, occupation and education level, bad appetite (OR=3.50, 95%CI: 1.18-10.62), unfixed food intake (OR=7.27, 95%CI: 1.40-35.83), and seldom or never intake of snack (OR=3.71, 95%CI: 1.42-9.72) were risk factors for malnutrition risk, while tea drinking was protective factor(OR=0.31, 95%CI: 0.11-0.93).@*Conclusion@#Risk of potential malnutrition and unhealthy diet behavior among the middle aged and elderly women with osteoporosis should be paid more attention. Unhealtghy diet behavior has a negative effect on their comprehensive nutritional status.
ABSTRACT
Objective To determine the prevalence of diabetes mellitus and related risk factors among residents in the urban and rural area of Chengdu.Methods A cluster sampling was used to establish a study population of inhabitants aged 30 to 70.Totally,1 847 participants were enrolled in this study.Questionnaire including general information and dietary information in the past year was used to collect related data.Height,body weight and oral glucose tolerance test (OGTT) were measured.Factor analysis was used to analyze the dietary pattern while multivariate unconditional logistic regression used for risk factors in total population,urban and rural residents,respectively.Results The population standardized prevalence rates of diabetes in the overall,urban and rural residents were 20.2％,28.7％,11.1％,respectively.Among total population,middle-aged (OR=2.337,95％CI:1.305-4.185) and the elderly (OR=5.990,95％ CI:3.389-10.586) residents had higher diabetes risk than the younger ones.Administrators (OR=1.434,95％ CI:1.000-2.057) and ordinary clerks (OR=2.870,95％ CI:1.653-4.980) were more vulnerable to diabetes than peasants.Similarly,middle-aged (OR=2.973,95％ CI:1.101-8.031) and elderly (OR=5.972,95％ CI:2.267-15.730) turned out to be more predisposed than young people in the urban area.Compared with peasants,ordinary clerks (OR=2.196,95％CI:1.213-3.975) seemed to be more liable to diabetes.In the mral areas,dietary pattern with higher energy and protein (OR=1.404,95％ CI:1.113-1.772) could be subject to diabetes.Conclusion The prevalence of diabetes in Chengdu was relatively high.Age,career and dietary pattern are mainly risk factors.The factors in different districts are vaious.Intervention on nutrition should be different,area-wise.
