ObjectiveThe prevalence of cardiovascular risk factors in congenital adrenal hyperplasia (CAH) varies widely. In the light of recent changes in treatment regimens, we have reassessed the prevalence of these risk factors in our current cohort of patients with CAH due to P450c21 deficiency. MethodsA retrospective cross-sectional study of 107 children (39m) with CAH aged 92years (range 04-205years). Anthropometric, systolic (SBP) and diastolic (DBP) blood pressure data were collected and expressed as standard deviation scores (SDS) using UK growth reference data and the Fourth Task Force data set, respectively. Fasting blood glucose with plasma insulin and lipids was measured, and insulin resistance (HOMA IR) calculated using the homoeostasis assessment model. Results236% (33% men; 18% women) of the cohort were obese (BMI SDS>2). BMI SDS was significantly higher (P<0001) when compared with the UK population. Nineteen (209%) of 91 patients (20% men; 21% women) had systolic hypertension and 8 [88% (86% men; 89% women)] had diastolic hypertension. Mean SBP [108 (SD 135)] mm Hg was significantly higher than the normal population (P<0001), but mean DBP was not (P=007). Both SBP SDS and DBP SDS were not related to BMI SDS. 95% of the subjects had hyperlipidaemia, but HOMA IR was more favourable compared with the normal population. ConclusionDespite a reduction in steroid doses over the last decade, a number of children with CAH are still obese and hypertensive. Whether this reflects general population trends or indicates a need to further optimize treatment regimens remains to be determined.
