| Objective:To investigate the prevalence of overweight, obesity and abdominal obesity and explore their relevant influencing factors in the residents of Henan Province in order to provide the baseline data and evidence for effective prevention and interventions.Methods:Through multistage sampling method, urban and rural residents aged 15-74 years were selected in 60 street offices /villages and towns in the whole province.18,942 participants was select for questionnaires survey and physical measurements. Epidata software version 3.1 was used to establish the database and SAS software version 9.1 was used to manage and analyze data.Results:1. The prevalence of overweight and obesityThe average BMI was(23.86±3.94)kg/m2. The average of BMI in urban area was(24.09±3.95)kg/m2 while(23.70±3.93)kg/m2 in rural area(t=6.64, P<0.001). The BMI is statistically different at the level of P<0.001 among different groups of age group based on the test of Pearson c2.The prevalence of overweight and obesity in the population was 31.10% and 13.99%.The prevalence of overweight was 31.37% for male and 30.89% for female(c2= 0.516, P= 0.473).The prevalence of obesity was 14.17% for male and 13.66% for female(c2= 1.331, P= 0.144). The prevalence of overweight in urban area was higher than that in rural area(32.04%, 30.47%; c2=5.169, P= 0.023) and the prevalence of obesity(15.54%, 12.95%; c2= 25.208, P<0.001). The trend of prevalence of overweight and obesity appreciably increased along with the age(P<0. 001). The prevalence of obesity is statistically different at the level of P<0.001 among different groups of ethnic group based on the test of Pearson c2. The prevalence of overweight and obesity is statistically different at the level of P<0.001 among different groups of marital status, occupationalgroups and education based on the test of Pearson c2 and decreased along with the education level(P<0.001).The prevalence of overweight and obesity in smoker and drinker was higher than non-smoker and non-drinker(P<0.05). The prevalence of overweight and obesity with physical exercise every week was lower than less one time physical exercise every week(P<0.05).2. The prevalence of abdominal obesityThe average waist circumference(WC) was(81.50±11.23) cm. The average of WC in male was(83.81±11.47) cm while(79.61±10.67) cm in female(t=25.736, P<0.001).The average of WC in urban area was(82.01±11.47) cm while(81.15±11.06) cm in rural area(t=5.139, P<0.001). The WC is statistically different at the level of P<0.001 among different groups of age group based on the test of Pearson c2.The prevalence of abdominal obesity in the population was 47.34.The prevalence of obesity was 46.59% for male and 47.95% for female(c2= 3.541, P= 0.063). The prevalence of abdominal obesity in urban area was higher than that in rural area(49.20%, 46.07%; c2=17.663, P<0.01). The trend of prevalence of abdominal obesity appreciably increased then gradually decreased along with the age(P<0. 001). The prevalence of abdominal obesity is statistically different at the level of P<0.001 among different groups of marital status, occupational groups and education based on the test of Pearson c2 and decreased along with the education level(P<0.001), but increased with BMI. The prevalence of abdominal obesity in smoker and drinker was higher than non-smoker and non-drinker(P<0.05). The prevalence of overweight and obesity with physical exercise every week was lower than less one time physical exercise every week(P<0.05).3. The relevant influencing factors of overweight, obesity and abdominal obesity.Through multi-factors Logistic regression analysis, it showed that district, age, drinking, marital status, education level, physical exercise were associated with overweight, obesity and abdominal obesity. As follows: urban(OR=1.113), 25~34 years old(OR=1.506), 35~44 years old(OR=2.398), aged 45~54(OR=3.101), 55~64years old(OR=2.644), drinking(OR=1.257), married(OR=2.142) and widowed(OR=2.134) were the risk factors of overweight and obesity. Middle school education(OR=0.782), high school education(OR=0.807) and physical exerciseevery week(OR=0.862) were the protective factors of overweight and obesity. Urban(OR=1.242), 25~34 years old(OR=1.561), 35~44 years old(OR=2.273), aged 45~54(OR=3.003), 55~64years old(OR=3.022), 65~74year old(OR=2.690), drinking(OR=1.222), married(OR=2.142) and widowed(OR=2.142) were the risk factors of abdominal obesity. Middle school education(OR=0.711), high school education(OR=0.724) and physical exercise every week(OR=0.905) were the protective factors of overweight and obesity.Conclusion:1. The prevalence of overweight, obesity and abdominal obesity in Henan in 2012 province higher than the prevalence of the whole nation in2010. Obesity is becoming a serious health problem in Henan province.2. The prevalence of overweight, obesity and abdominal obesity were increased sharply than that ten year ago in Henan province.3. Overweight, obesity and abdominal obesity have same risk factors. They are higher age, drinking, married/widowed, lower education level and the less one time physical exercise every week. |
