A study regarding the control attempts on body weight and related factors among overweight and obese adults in China, 2013 / 中华流行病学杂志

ABSTRACT

Objective@#To understand the control attempts of body weight and its related factors among overweight and obese adults in China.@*Methods@#Data was from the 2013 Chinese Chronic Diseases and Risk Factors Surveillance Program, which covered 302 surveillance sites. 179 570 adults, selected through multistage stratified cluster sampling method, were interviewed. Demographic characteristics and weight-control attempts were collected via face-to-face interview. BMI, waist circumstance and blood pressure were individually measured under physical examination. Venous blood samples were obtained and tested for FPG, OGTT-2h, TC, TG, LDL-C and HDL-C. A total of 87 545 overweight and obese patients were included in this study, with the exclusion of 152 patients having the missed critical information. Rates on weight control and attempts were analyzed, using the complex weighting on samples to represent the overall overweight and obese adults in China.@*Results@#The rate of weight-control attempts was 16.3% (95%CI 14.9%-17.7%). Among all the 12 133 patients who had undergone weight-control measures, the proportions of different attempts were as follows diet (40.9%, 95%CI 38.4%-43.3%), combination of diet and physical activity (31.5%, 95%CI 28.9%-34.0%), physical activity (22.8%, 95%CI 21.0%-24.6%) and drug control (1.3%, 95%CI 1.0%-1.7%). Factors as being female (OR=1.26, 95%CI 1.15-1.38), at younger age (18-44 years old, OR=1.51, 95%CI 1.31-1.74), with high education levels (college degree or above, OR=4.52, 95%CI 3.76-5.43), having high annual income (≥24 000 Yuan, OR=1.94, 95%CI 1.63-2.30) etc., appeared as favorable factors for taking the measures vs. rural residency (OR=0.63, 95%CI 0.55- 0.72) as the unfavorable one.@*Conclusion@#The rate of weight-control attempts appeared low among the overweight and obese adults who were affected by factors as age, education and income level. Personalized intervention measures should be carried out for people with different characteristics.
