In the first year of life, 90% of children are regularly supervised by the periodic health examinations (examination no 3 to no 6). From the beginning of the second year of life, the participation rate is continuously decreasing up to 75% at the last examination at 5 years. Results of school entrant examinations could demonstrate that the real participation rate is less than reported.
