Childhood obesity, caused by reduced physical activity and increased food consumption, has reached epidemic proportions. We hypothesized that a single practitioner could enable a child to reduce BMI by educating towards a healthier lifestyle and then reinforcing the message in a structured manner. In this study, intervention group participants and their parents received a half-hour talk on exercise and diet, repeated after 3 months. They were instructed to fill weekly diaries and were called weekly by telephone. Controls received the initial instruction only. Twenty-seven (14 intervention) obese children were recruited. Anthropometric parameters, fitness and biochemical data were collected before intervention and after 6 months in both groups. Sustained but not statistically significant improvements in attitude, BMI SDS and LDL-cholesterol were noted in the intervention group. These promising results support a need for further work to evaluate the efficacy and applicability of our approach in the population at large.
