Abstract

The main aim of this paper is to propose a probability model to describe the distnbution of females accordmg to age at menarche. The suitability of the proposed model has been tested with the real data set. Expected waiting time at blrth for attaining menarche has also been computed by using life table technique. The data have been taken from a sample survey in Palpa and Rupandehi districts. The proposed logistic distribution was found well fit for describing the dstribution of age at menarche in Nepal. It was found that the estimated mean age at menarche was 14.6 years. The expected waiting time at birth for getting menarche was found to be 14.7 years, whch is more or less consistent result. The finding  may give useful information for policy implications to design the policies and programmes especially in fertility and reproductive health related issues of a country.
