Approximate Prevalence of Obesity-associated Conditions

Prader–Willi1/25 000 Population77
Other genetic disordersUnknown (often reportable)
Hypothyroidism1–2/1000 School children78
Cushing's syndrome1/140 000 Population in Japan79
Slipped capital femoral epiphysis1/3 300 <25 Years and >95th percentile weight80
Blount's diseaseProbably equals slipped capital femoral epiphysis33
Pseudotumor cerebri1–2/8000 Obese adults and adolescents81
Sleep apnea1/100 In pediatric obesity clinic36
Obesity hypoventilationLess frequent than sleep apnea36
Gall bladder disease1–2/100 In women >30 kg/m2(41)
NIDDM1/1400 Children age 10–1947
Polycystic ovary syndrome1–3/4 Adolescent and adult women with oligomenorrhea or amenorrhea82
Hypertension1/4 Obese children 5–11 years (blood pressure >90 Percentile)83
Dyslipidemias1–3/30 Young adults with BMI
>28 kg/m2(84)
1–2/5 Children with TSF >85 percentile have total cholesterol in 5th quintile85
  • Case definition, size, and characteristics of the population studied all affect the reported prevalence. The prevalence of these conditions in obese children in a primary pediatric practice may differ markedly.
