  abstract = {{A}ge at menarche was investigated using data collected from demographic surveys ({WFS}, {DHS}) conductedin {N}igeria between 1982 and 2018, all of which were based on large representative samples of the femalepopulation. {L}inear-logistic regressions were used to estimate mean age at menarche, its trends and its riskfactors. {M}ean age at menarche had underwent a marked secular decline from 15.02 years for girls born in 1933 to 13.78 years for girls born in 2003. {I}n multivariate analysis, height (stature), body mass index ({BMI}), level of education and household wealth had independent effects on age at menarche, whereas urbanresidence had no effect. {S}ocioeconomic gradients were large:+9 years of schooling was associated with a-0.52 year decrease in age at menarche, and+2 standard deviations in household wealth with a-0.33year decrease. {T}he impact of anthropometry was even greater:+2 standard deviations in height was associated with a-0.99 year decrease in age at menarche, and+2 standard deviations in {BMI} with a-1.42 yeardecrease. {N}orthern provinces had a higher mean age at menarche than southern provinces. {C}ompared withindependent sources, long-term trends in age at menarche, as well as their fluctuations, appeared to becorrelated with trends and fluctuations in incomeper capitaand in under-five mortality, but not withdivergent trends in adult height.},
