Several recent studies explained that the onset of puberty in young female has became earlier during the last 50 years. The age of young female menarche is an important indicator in the process of puberty. This is influenced by endogenous factor which is genetic and exogenous factors which are family economic status, nutritional status, race/regional origin, the number of families, and physical activity. The earlier age of young female menarche would increase the risk of pregnancy at younger age, the risk of breast cancer, and risk of young female unpreparedness in dealing with problems arising from menarche.
The aim of this study is to obtain information about the average age of young female menarche in elementary and lower secondary schools in Kemuning District Palembang, and determine the factors associated with their menarche age. The factors that studied in this study were family economic status, young female nutritional status, race/regional origin, the number of families, physical activity, the activity of watching television, parental education, and age of maternal menarche.
This study is an observational study with cross sectional design. A sample size of 266 young female derived by random method from 3 elementary and lower secondary schools in the District Kemuning Palembang.
