Prevention of Obesity in Toddlers (PROBIT) Trial.

AIM: to reduce the prevalence of overweight and obesity at two years of age in the intervention group compared to the control group. METHODS: Eleven primary paediatricians were randomized to the intervention group and intensively trained about the trial intervention. Each of them was asked to consecutively recruit the parents of at least 30 newborns taken in charge within the first six months of the study, and to provide them with standardized oral and written information on protective practices during all the well visits scheduled in the first two years of the child's life. Another eleven primary paediatricians were randomized to the control group, and were asked to consecutively recruit the parents of at least 30 newborns taken in charge within the first six months of the study and to provide them with usual care and follow-up. When all recruited children have completed the second year of life, the two groups of toddlers will be compared as regards the prevalence of overweight/obesity, defined by WHO cut-offs of the weight/length ratio.
