Mean Age at Menarche among Four Endogamous Populations of Coastal Andhra Pradesh

Age at menarche and body mass index (BMI) among adolescent secondary school girls in Port Harcourt, Nigeria

“…Raji et al 10 in 2006, also reported a comparably higher mean age at menache of 13.66 ± 1.82 years at Ibadan and Ogbomosho in Western Nigeria. The difference in menarcheal age may be as a result of tribal differences in the four study populations as reported by Danborno and Oyibo 14 in Nigeria and Prakash et al 27 in India. The subjects in the present study are predominantly Ijaws, those in the Maiduguri study are predominantly Hausas while those in the Ebonyi State study and Western Nigeria study are predominantly Igbos and Yorubas respectively.…”
