Puberty development among children and adolescents with chronic disease in Saudi Arabia

ABSTRACT

Increasing numbers of children with chronic health conditions are now surviving into adolescence and adulthood because of advancing health care. These chronic health conditions are generally known to impact a child's growth and development, including pubertal development. In Saudi Arabia, chronic diseases are prevalent, yet no reports of pubertal onset and its relation to chronic illness are available. The aim of this study was to explore pubertal development among Saudi children and adolescents with a chronic illness. Cross-sectional study conducted at schools in Riyadh, Saudi Arabia in 2006. Those students whose parents reported that their son/daughter had a chronic illness and/or was taking a long-term medication underwent a physical examination to determine sexual maturity rating and growth parameters. Of 1371 students who participated in the study, 155 [11.3%] had a chronic illness. Of those, 79 [51%] were male, and the mean SD age of all the students was 11.4 [2.4] years. Ninety [58%] students were taking medication for their health condition. Bronchial asthma was reported to be the most common chronic condition [n=66; 42.6%], followed by blood disorders [n=41; 26.5%]. Fifty-three [34%] students were overweight or obese. For male gonadal [G] development, the mean age of boys with G stage 2 was 11.7 years; stage 3 13.5 years; stage 4 14.1 years; and stage 5 14.6 years. For female breast [B] development, the mean age of girls with B stage 2 was 10.7 years; stage 3 11.3 years; stage 4 12.4 years; and stage 5 14.1 years. The pubic hair development for both boys and girls was similar to the corresponding gonadal or breast development, respectively. The age of onset of pubertal development for both boys and girls with a chronic illness are within normal limits. The high prevalence of overweight and obesity may contribute to this phenomenon, yet further studies should consider the effects of disease severity and chronicity and medication use as possible confounders
