Part I: developmental issues JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 938 OP 942 DO 10.1136/adc.2003.045369 VO 89 IS 10 A1 J-C Suris A1 P-A Michaud A1 R Viner YR 2004 UL http://adc.bmj.com/content/89/10/938.abstract AB The prevalence of chronic conditions among adolescents is difficult to assess due to the lack of quality data focusing specifically on this age group, as well as the diversity in methodology and definitions used. However, surveys carried out by self administered questionnaires among in-school adolescent populations indicate that around 10% of adolescents suffer from such a condition. The aim of this paper is to analyse the reciprocal effects of chronic conditions and adolescent development by reviewing the effect of chronic disease on growth and puberty and on psychosocial development, and the effect of developmental issues on the course and management of chronic disease.
