Context: A secular trend of progressively earlier attainment of menarche has been described in various populations. The existence of this trend in Ile-Ife, Nigeria, has not been documented. Aim: To determine the current age of menarche and its trend in comparison with previous studies among secondary school girls in Ile-Ife, Nigeria. Settings and Design: School-based cross-sectional analytical study. Materials and Methods: Three-hundred secondary school girls in the lower four classes (JSS 1--SSS 1) were studied. Sociodemographic and menstrual data such as cycle length, duration of menstrual flow, and presence of dysmenorrhoea were obtained using a structured self-administered questionnaire. The mean age at menarche was compared with figures from previous local studies to determine the trend in Ile-Ife. Menstrual characteristics were also analyzed. Statistical Analysis: Data was analyzed with SPSS version 20. Means and standard deviations were generated for continuous variables, while frequencies and proportions were determined for categorical variables. Results: Out of the 300 subjects studied, a total of 198 (66%) had attained menarche at the time of this study. Their reported ages at menarche ranged from 11 to 17 years with a mean of 13.08 ± 1.61 years. This was lower than the 13.98 ± 1.30 and 13.94 ± 1.31 years reported in Ile-Ife in 1992 and 1997, respectively. These three figures show a trend of progressive decline in the mean age at menarche. The subjects' mean duration of menstrual flow was 4.26 ± 0.87 days, with 97.5% of them reporting flow of ≤5 days. Only 22 (11.1%) of the respondents had a cycle length of 28 days. Dysmenorrhoea was reported by 75% of the respondents and 24% reported loss of concentration during periods. Conclusion: Similar to the widely reported secular trend, menarche indeed appears to be occurring progressively earlier in Ile-Ife, Nigeria.
