Age at menarche and the related issue: A pilot study on urban school girls

Age at onset of menarche was determined for a group of newly menstruating urban schoolgirls in Bangladesh. Their age at onset of menarche was correlated with their weight, height, and per capita food expenditure (PFE). Results indicated that these girls began menstruation at 12.67 years of age, which is well ahead of rural girls. Age at onset of menarche was positively correlated with weight and negatively correlated with PFE. A strong inverse relation between weight and height of newly menstruating girls indicated the existence of some unstable trend in their physiological processes.Major interests are population education, adolescent psychology, and education.
