| Objective We are in order to learn about the phenomenon of overweight and obesity, discuss the relationship between multiple factors and the phenomenon, prevent and relieve the overweight and obesity morbidity, provide with the foundation for establishing a medical care system for civil servants based on the analysis of physical examination data from civil servants from some city of Hunan.Method Under the method of multistage sampling, we census the overweight and obesity occurrence through questionnaire (mainly including general situation, medical history, smoking history, drinking history and exercise), stature and weight measurement, BMI calculation from12837civil servants of our city coming to our hospital for check-up between January and December of2010. After general description, we separate the respondents into a normal group and an overweight one according to BMI, describing the distribution of age, gender, marriage, smoking, drinking and exercise within the two groups, comparing the states of the two using the test of Pearson χ2and conducting the single factor analysis, including the six factors in the multinomial logistic regression, studying the relationship between overweight and these factors. We assume the a as0.05which is statistically meaningful.Result1. The BMI is23.97±3.10, the overweight percentage is37.90%, the obesity percentage is10.12%.2. The male overweight and obesity percentage is63.96%and the female overweight and obesity percentage is29.91%which is significantly lower than that of the male at the level of P<0.001. 3. The overweight and obesity percentage grows as aging. The percentage of the group between60and69years old is56.92%, which is the highest. The percentage of the group below30years old is29.24%, which is the lowest. The overweight and obesity percentage distribution is statistically different at the level of P<0.001among different groups of various age based on the test of Pearsonχ2.4. The overweight and obesity percentage of married civil servants is48.76%and that of unmarried ones, or divorced ones, or widow/widower is30.84%, which is lower. Overweight and obesity for which could be accounted by the factor of marriage is statistically different at the level of P<0.001.5. The overweight and obesity percentage of civil servants often drinking is66.93%, which is the highest. The percentage of civil servants seldom drinking is51.09%, which is in the next place. The percentage never drinking is42.75%, which is the lowest. The overweight and obesity percentage for which could be accounted by various drinking frequency is statistically different at the level of P<0.001.6. The single factor analysis suggests that the overweight and obesity percentage is related to smoking. The overweight and obesity percentage of people who smoke is63.36%and that of people who never smoke is42.80%, which are statistically different at the level of P<0.001. The factor of smoking is not included in the regression equation in the unconditioned logistic regression analysis.7. The overweight and obesity percentage of civil servants who exercise less than once a week is49.95%, which is the highest. The percentage of people who exercise three times a week is49.83%, which is in the next place. The percentage of people who exercise once or twice a week is43.90%, which is the lowest. The overweight and obesity percentages for various frequency of exercise are statistically different at the level of P<0.001.8. The unconditioned regression analysis suggests that the gender, age, drinking and exercise in the regression equation are reasons for overweight and obesity.(1) Gender:The male gender is a risky factor for overweight and obesity of civil servants. The risk of overweight and obesity for males is3.950times as that for females.(2) Age:The risk suffering from the overweight and obesity is increasing as aging. The risks of overweight and obesity for groups with age ranges between30and39years old, between40and49years old, between50and59years old, between60and69years old, and above70years old are respectively1.315,2.044,2.391,3.120,2.309times as that for the group with age range below30years old.(3) Marriage:Marriage is a risky factor for overweight and obesity and the risk for married ones is1.327times as that for unmarried ones.(4) Drinking frequency:Drinking is a risky factor for overweight and obesity and the risk for ones seldom drinking is1.115times as that for non-drinkers and the risk for ones often drinking is1.438times as that for non-drinkers.(5) Exercise frequency:Exercise is a factor for preventing with overweight and obesity and the risk for ones exercising once or twice is0.867times as that for ones never exercising and the risk for ones often exercising above three times is0.900times as that for ones never exercising.Conclusion1. The overweight percentage is37.90%and the obesity percentage is10.12%, which manifests that the overweight and obesity morbidity is serious among civil servants. 2. The male gender, aging, marriage, drinking, frequency of exercise less than once a week are risky factors for overweight and obesity. |
