• Epidimologial Study of Menarche-A Case Study Among Urban Areas of District-Bhagalpur

Abstract

The present research deals with all the developmental milestones associated with the adolescent year and menarche among girls is the most noteworthy. Many interrelated factors may influence menarchial age. These factors are socio-economic status (nutrition, health, family size, & living conditions) geographic environment (temperature, altitude, humidity and seasonal rhythm)and genetic influences (race/ethnic group  family heredity, & constitutional type)in which more than 700 respondent were taken in account whose exact date of birth and exact date of menarche were known. Out of 800 respondents only 562 were in the above categories, hence rest respondents were discarded. Present research undertaken comprised of 2/3 of the total respondents and 1/3 of the total were discarded. A change in some of these factors is known to cause an increase or decrease in the onset of menarche.
