High prevalence of overweight (45%) and obesity (30%) were recorded in French Hajj pilgrims originating from North Africa. Females were significantly more likely to suffer from obesity compared to males. The overall prevalence of obesity among French pilgrims born in North-Africa was twice that of the overall French population. The prevalence of obesity in pilgrims aged 55-64 years and 65 years and over were respectively 38 and 25% compared to 20 and 18% in the corresponding overall French population age classes. The prevalence of diabetes in French pilgrims was five times higher compared to that of the overall French population. This situation prompts us to organize in the next future, pre-Hajj education seminars for diabetics.
