Effects Of Health Education And Aerobic Exercise Comprehensive Intervention On People With Overweight And Obesity

Objective:To evaluate the effects of intervention of regular aerobic exercise and health education on KAB, SAS scores, BMI, waist circumferences, blood pressure, serum glucose and blood lipids in middle-aged and elderly people with overweight and obesity.Methods:3 smaller resident communities were choosen randomly from wangdingdi community in nankai district in Tianjin. Totally 130 overweight people were involved in this study.65 and 65 people were randomly assigned to intervention group and control group respectively. The members of intervention group were asked to participate in aerobic exercise and health education program 3 times per week. And control group members received no intervention. The demographic, anthropometric data and medical examination, including serum glucose, blood pressure and blood lipids were collected at the beginning of the study and at the end of the study after six months. Then to evaluate the effects of intervention of regular aerobic exercise and health education on BMI, waist circumferences,blood pressure, serum glucose and blood lipids in middle-aged and elderly people with overweight and obesity by using a repeated-measures ANCOVA. In all cases, a P＜0.05 was considered as statistically significant level.Results:No significant differences were found between the intervention group and the control group in gender and age distribution. KAB scores, SAS scores, BMI, waist circumference, serum glucose, blood pressure, total cholesterol, HDL cholesterol, LDL cholesterol were not significantly different between the intervention group and the control group at baseline.96.4% patients in the intervention group completed the six-month aerobic exercise and health education program. The results showed that the comprehensive intervention resulted in significant reductions in intervention group in SAS scores(-9.85 [95%CI:-11.07 to-8.64]), BMI(-0.47 [95%CI:-0.58,-0.36]kg/m2), waist circumference (-4.00 [95%CI:-5.01,-2.99]cm), SBP(-11.69 [95%CI:-13.84,-9.55]mmHg), FPG (-1.21 [95%CI:-1.55,-0.88] mmol/L), triglyceride (-0.06 [95%CI:-0.25,0.13] mol/L), LDL cholesterol (-0.48 [95%CI:-0.62,-0.34] mmol/L), and improvement of the KAB scores (13.82 [95%CI:12.42, 15.23]) and HDL cholesterol (0.22 [95%CI:0.17,0.28] mmol/L). And between-groups comparisons showed a significant difference in proportion of BMI and SAS score. The proportions of overweight and obesity were decreased from 66.1% and 33.9% to 62.9% and 30.6% respectively; and BMI of 6.5% people changed to normal in intervention group, while the proportion of obesity was increased from 41.3% to 42.9%,the proportion of overweight was decreased from 58.7% to 57.1% in control group. The proportion of people with SAS score above 40 was decreased from 17.7% to 3.2% in intervention group. In comparison to intervention group there was only a smaller decrease from 27.0% to 20.6% in control group.Conclusion:Six-month period of regularly aerobic exercise and health education program in community can successfully reduce BMI, waist circumference and some other risk factors related to overweight and obesity. It is effective to improve awareness, physical fitness, psychological state for middle-aged and elderly people.
