Obesity is a multi-faceted condition. A team of Endocrinologists, dietitians, exercise therapists and psychologist collaboratively designed a 12-week program which included a weekly 1-hour discussion with the dietitian or psychologist followed by a 1.5-hour exercise session. This aims to evaluate the program and its impact on weight, body composition and functional outcomes.
Twenty-seven obese adults (44.8±15.2 years, 47% female, BMI 38.1±0.99kgm-2, 76.6kg to 141.9kg) were recruited from weight management clinic between June 2018 to July 2019, at 70% completion rate over 4 separate runs of 6-7 participants in each group.
At the end of program, weight loss of 1.45kg (-16.7kg to 3.3kg) was observed with 25% participants achieving at least 5% weight loss. There was an improvement in the 6-minute walk test from 479.5m (277m to 640m) to 506m (324m to 642m), reduction in percentage body fat of 1% (-2.5% to 2.2%) and increased in fat free mass of 0.05kg (-3.0kg to 0.3kg). Improvement in eating habits was also observed. Many participants reduced portion size of food and drinks, reduced mindless eating and slowed down their speed of eating. Participants who were more likely to drop out were below 55 years (p<0.05), females (p<0.05) and at lower stages of change (p<0.05). Post survey showed 93% of participants found the program helpful.
This evaluation shows that the program can deliver positive outcomes in patients who completed the programme. The challenges faced include recruitment, dropout and collation of outcome measures. Further understanding of participants’ needs would guide program enhancement.
