BACKGROUND Age at menarche is a significant indicator of growth and sexual maturation in girls. During adolescence, anthropometry provides a tool for monitoring and evaluating the hormone-mediated changes in growth and reproductive maturation. OBJECTIVES We aimed to examine the anthropometric status of pre- and post-menarcheal Nigerian adolescent girls attending senior secondary schools. MA...

Menarche is the first period of menstruation in woman reproduction cycles. Several epidemiology study revealed the earlier onset of age of menarche. Better nutritional status, e.g. overweight-obese, is considered as one factor contributes to this condition. We want toknow the association between overweight-obese girls and age of menarche. A cross sectional study was performed in SDN 1 Kleco Sur...

OBJECTIVE To determine the relationship between anthropometric indices and the age of menarche in female students of Sabzevar, Iran. METHODS The cross-sectional study was conducted in Sabzevar, Iran, from April to September 2010, and involved girls of 11-18 years of age. The required sample size for analysing the relationship between menarche age and Body Mass Index was estimated to be 110 by...

OBJECTIVES To estimate the shifts in age at menarche from 1985 to 2010, compare the differences of average age at menarche between urban and rural groups, and determine the association of menarche with body mass index (BMI). STUDY DESIGN The data were obtained from 4 cross-sectional Chinese National Surveys on Students' Constitution and Health (1985, 1995, 2005, and 2010). In this representat...

Tissue iron stores are commonly assessed by measuring serum ferritin. Adolescent girls are more prone to develop iron deficiency due to menstrual blood loss. Menstruation is an inflammatory process and we hypothesized that serum ferritin levels may be elevated during menstruation as it is an acute phase protein and hence serum ferritin measurement alone may not be truly reflective of iron statu...

The authors compared the frequency of epilepsy onset in perimenarche with epilepsy onset in other childhood periods in 94 postmenarchial patients aged <55 years. Seizure onset was higher for the 12 to 15 year age bracket than for other ages and clustered around menarche. Epilepsy began during the year of menarche in 17% of patients vs 5.5% expected (p < 0.001), and during +/-2 years of menarche...

BACKGROUND The menstrual practices of adolescents derive largely from health issues associated with their adjustment to reproductive life. The objective of the study was to assess the effect of pre-menarcheal training on the menstrual and hygiene practices of Nigerian school girls. METHOD A cross-sectional questionnaire-based survey of randomly selected post-menarcheal school girls using a pr...

BACKGROUND Several studies have shown that girls who undergo menarche at a relatively young age tend to be more obese as adults. However, because childhood (pre-menarcheal) levels of weight and height are associated with an earlier menarche, the increased prevalence of adult obesity among early maturers may largely reflect the persistence of childhood obesity into adulthood. METHODS We examin...

BACKGROUND Declining age at menarche has been observed in many countries. In China, a decrease of 4.5 months per decade in the average age at menarche among the majority Han girls has recently been reported. However, the trends in age at menarche among ethnic minority girls over the past 25 years remain unknown. OBJECTIVES To compare the differences in median age at menarche among girls aged ...

OBJECTIVE To evaluate the age at menarche of girls, with or without weight excess, attending private and public schools in a city in Southeastern Brazil. METHODS This was a cross-sectional study comparing the age at menarche of 750 girls from private schools with 921 students from public schools, aged between 7 and 18 years. The menarche was reported by the status quo method and age at menarc...
