Health Status Of Middle-aged And Elderly People In A Rural Area Of Laixi And Effects Of Health Education

Objectives To investigate the prevelance rate of nutrition-related diseases of middle-aged and elderly people in a rural area. And to evaluate effects of health education on decreasing the prevelance rate of the nutrition-related diseases.Methods Totally 1661 middle-aged and elderly people were randomly recruited and then got a body check for body height, body weight, waist circumference, hip circumference, blood pressure, blood glucose and hemoglobin. The status of nutrition-related diseases were investigated and the relevant index were analyzed. All subjects were randomized into two groups and the intervention group accepted health education for seven months. The status of nutrition-related diseases were compared at the end of the trial.Results The age-standardized prevalence rate of anemia of middle-aged and elderly people was 33.7%, which was higher than the rate of nationwide in 2002 (9.9%)and that of Qingdao rural areas in 2002 (26.9%). And after the age of 55 years old, the prevalence rate of anemia rised with age(P<0.05); The age-standardized prevalence rate of hypertension was 58.6%, which was higher than the rate of nationwide in 2002(46.2%) and that of Qingdao rural areas in 2002(35.8%). The prevalence rate of hypertension also rised with age(P<0.05); The age-standardized prevalence rate of diabetes was 11.2%, which was higher than the rate of nationwide in 2002(6.4%) and that of Qingdao rural areas in 2002 (3.5%); The age-standardized prevalence rate of overweight and obesity of was 66.9%, which was higher than the rate of nationwide in 2002 (57.4%) and that of Qingdao rural areas in 2002(30.7%). The rate of overweight and obesity in female was higher than that in male(P<0.05).There was a positive correlation between BMI, WC, WHR and WHtR(P<0.01), and the correlation index between WHtR and WC was the highest(r=0.911). BMI,WC,WHR and WHtR all had positive correlations with systolic pressure, diastolic pressure and blood glucose, while WHtR had the highest (P<0.01). After the 7-month health education, the prevalence rate of anemia of the intervention group decreased from 32.2% to 3.1%(P<0.05), while that of the control group decreased from 32.2% to 6.6%(P<0.05). The educational group decreased more than the control group(P<0.05). The prevalence rate of overweight and obesity of the intervrntion group decreased from 61.4% to 49.4%(P<0.05), while that of the control group unchanged(P>0.05). The prevalence rate of overweight and obesity of female of the educational group decreased (P<0.05), and that of the male remained unchanged (P >0.05). The prevalence rate of overweight and obesity of the 45-and 55-age groups in the educational group decreased (P<0.05), and that of 65-and 75-unchanged(P >0.05). After the 7-month health education, the prevalence rate of hypertension of both the intervrntion group and the control group remained unchangged(P>0.05).Conclusion The prevalence rates of nutrition-related diseases of middle-aged and elderly people in rural ares are still high. Health education can decrease the prevalence rate of some nutrition-related diseases, which suggests that health education should be routinely conducted to the middle-aged and elderly people in rural areas.
