Multi-site randomised trial of a weight management program for overweight and obese children: 6- and 12-mo outcomes from HIKCUPS (Hunter Illawarra Kids Challenge Using Parent Support).
The aim of this study was to evaluate and compare the effectiveness of three interventions in preventing unhealthy weight gain in overweight and obese children: 1) a parent-centred dietary modification program; 2) a physical activity skill development program; and 3) a parent-centred dietary modification + physical activity skill development program. All interventions were performed in a community setting and were designed to be inexpensive and sustainable. Six- and 12-month outcome data are reported in this paper. An assessor-blinded randomised trial involving 165 overweight and obese 5-9-year-old children and their parents was conducted in Wollongong and Newcastle, NSW, in 2005 and 2006. A total of 114 participants (69%) completed 6-month follow-up and 107 (65%) completed 12 months. Participants were randomised to one of the three interventions. Each consisted of 10 face-to-face sessions over 10 weeks followed by 3 follow-up phone calls over 3 months. Intention-to-treat analysis showed that there were statistically significant improvements in one of the two primary outcome measures (BMI z-score), and two secondary outcome measures (LDL/HDL cholesterol, energy intake [kJ/kg]) across all groups from baseline to 12 mo.
