Objective - To evaluate the process and content of a health interview conducted at the onset of adolescence and to assess its impact on public health based on a pilot study conducted in three departments. Method - Families in the Aisne, Gironde, and Yvelines departments with a 12-year-old daughter or a 13-year-old son were invited by their health insurance provider to bring their child for a consultation with a private physician of their choice during the 2006-2007 school year. An individual summary form was completed by the doctor, indicating the child’s general state of health and, in particular, any health issues identified. Results - The participation rate among children reached 8.7%. At least one child was seen in a consultation by 35% of the doctors in the departments involved: one-third of general practitioners and two-thirds of pediatricians. The consultation lasted an average of 30 minutes, allowing for a significant amount of time for dialogue between the child and the doctor. A health issue was identified during this consultation in 12.5% of the children; these were mainly benign or transient adolescent disorders. Conclusion - Due to the low participation rate and what is likely a limited impact on the children who need it most, it is necessary to improve or modify the protocol for this preventive initiative at a key stage of child development.
