Learning Objective 1: to normalized body weight in overweight adults though health promotion model.
Learning Objective 2: to modified physical activity and eating pattern in overweight adults though health promotion model.
Methods: A quasiexperimental trial with 70 healthy free-living overweight adults, mean(+SD) age 42.66 +13.80 year-olds, from Arthid and Nang Nong 2 communities in Chomthong district, Bangkok were recruited. Arthid community was assigned to intervention group (IG) (n=36) whereas Nang Nong 2 community was assigned to control group (CG) (n=34). Lifestyle modification program of IG are including a one day day-camping at the beginning of study and provided continuous health education, counseling, empowerment, self monitoring and focus group discussion for 16 weeks. Lifestyle, including eating and physical activities pattern, anthropometry, and cardiovascular risk assessments were assessed at baseline and at the end of the intervention
Results: At week 16, mean (±SD) of eating and physical activities pattern, self efficacy of food and exercise control score were significant increased in IG than CG and no significant difference in knowledge of eating and physical activities for weight control score between IG and CG. There were significant differences in percentage changes of the intervention group relative to the controls, from the base line to 16 weeks in waist and hip circumference, (IG, 0.2+4.5 and -1.1+3.1; CG,6.8+5.4 and 3.2 +3.4; p< 0.00), WHR(IG,1.1+4.6; CG,3.5+4.5 ; p< 0.03), triceps skin fold(IG,–15.1+10.5; CG,-8.4+14.0 ; p< 0.02), mid upper arm circumference(IG,–3.0+4.8; CG,5.4+5.2 ; p< 0.00), systolic blood pressure (IG,–7.9+25.7; CG,1.3+10.6 ; p< 0.05) and Framingham score (IG,–53.9+136.7; CG,22.6+136.6 ; p< 0.05). No significant changes in BMI, Biceps skin fold, sub scapular skin fold and ten year hard CHD risk between IG and CG. The satisfaction of IG in this health promotion model was 81.8%.
Conclusion: This health promotion model indicates effectiveness in weight controlling in overweight adult. However, a randomized control trial (RCT) is needed to establish causality of these initial observations.
