There is little data in the literature on the prevalence of obesity in the population of HIV patients. In France, the prevalence of obesity in the French Hospital Database on HIV is 15.1% among women and 5.3% among men, similar to prevalence in the general population. Patients born in sub-Saharan Africa have a higher risk with 20.7% versus 12.2% in women and 10.9% versus 4.7% for men.
