IOSR Journals , 2019
Background: The age at menarche as well as other changes that occur during puberty are actually due to major and specific hormonal changes that occur in the body at puberty. The purpose of this study was to assess factors affecting the age at menarche in this environment, and obtain an actual reliable data on the age at menarche. Methods: A cross sectional study was carried out in Yenegoa, Bayelsa state. Random sampling method was used and Data were collected using a self-administered structured questionnaire on menstruation. This study investigated the age at menarche of 400 secondary school girls between the ages of 10-20 years. This research was carried out under the supervision of the research team. Data was analyzed using SPSS version 13. Result: results showed that a girl from a high socioeconomic class (SEC) had a mean menarcheal age (MA) of 12.84±1.07, middleSEC had 13.36± 1.30 and low SEC had 13.65±1.5. Girls exposed to rich diet from childhood had mean MAof 12.91±1.12, those of average diet 13.26±1.30, and those with poor diet 13.61±1.24. Girls exposed to stress factor had a meanMA of 13.20±1.22, those without stress factor had mean MAof 13.18±1.28. Conclusion: This study showed that parameters such as socioeconomic group, dietary type and developmental status have influence on the age at menarche, while stress factor had no influence on age at menarche.
Age at menarche and the related issue: A pilot study on urban school girls
Journal of Youth and Adolescence, 1984
Age at onset of menarche was determined for a group of newly menstruating urban schoolgirls in Bangladesh. Their age at onset of menarche was cotv'elated 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.
Age of menarche among basic level school girls in Medina, Accra : original research article
African Journal of Reproductive Health, 2011
The current study was designed to determine the age at which menarche occurs among school girls in Madina, Accra. A survey was conducted among 529 girls selected using multi-stage sampling from basic schools in Madina, Accra. Respondents completed a questionnaire that recorded age-at-first menstruation by recall, household characteristics, and anthropometry. Mean age at menarche was 12.74 ± 1.15 years; probit analysis yielded a median age of 12.09 years. Menarcheal age was significantly correlated with current age (r=0.48; p<0.01). Most girls (90%) had first menstruation before age 13. Their mothers' mean age at menarche was 13.6 ± 1.08 years. In a multivariate linear regression model, household wealth (p<0.01) and body mass index (p<0.01) were the main modifiable independent predictors of age at onset of menarche. School girls in Madina attained menarche earlier than previously estimated. Our study suggests an influence of household level improvement in socioeconomic status on menarcheal age (Afr J Reprod Health 2011; 15[3]:103-110). Résumé Age de l'établissement de la menstruation chez les écolières à Medina, Accra : L'étude actuelle a été conçue en vue de déterminer l'âge auquel la menstruation s'établit chez les écolières à Medina, Accra. Une enquête a été menée auprès des 529 filles à l'aide d'un échantillon à multiples étapes tirée des écoles à Medina, Accra. Les enquêtées ont rempli un questionnaire qui a enregistré l'âge à la première menstruation à travers le rappel, les caractéristiques familiales et l'anthropométrie. L'âge moyen à la première menstruation était 12,74±1,15 ans ; une analyse par la méthode des probits a donné un âge médian de 12,09 ans. L'âge qui se rapporte à l'établissement de la menstruation était remarquablement corrélé avec l'âge actuel (r=0, 48 ; p<0,01). La plupart des filles (90%) avaient leur première menstruation à l'âge de 13ans. L'âge moyen de leurs mères au moment de la menstruation était 13,61±08 ans Dans un modèle de régression linéaire multifactoriel, la richesse du ménage (p<0,01) et l'indice de masse corporelle (p<0,01) ont été les principaux indices modifiables de l'âge au commencement de la menstruation. Quelques écolières à Medina ont commencé la menstruation plus tôt qu'on avait prévue. Notre étude montre qu'il y a une influence de l'amélioration du niveau du ménage dans l'état socio-économique sur l'âge qui se rapporte à l'établissement de la menstruation (Afr

Menarche age is an indicator of a girl's puberty besides the clinical assessment of detecting deviations. This study aimed to search the pattern of menarche age (normal, early and late) and its relationship with some demographic characteristics in girls and their parents. This cross-sectional study was done on girls aged between 9 and 18 years old in Shiraz city. About 2000 students were selected through cluster sampling. Data collection was done by applying a demographic information form. Finally, the data were analyzed using SPSS software. About 1386 students (69.3%) had the history of menarche (at least once). The mean age of menarche was 12.26±1.11 years in Shiraz. The menarche age of the girls ranged from 9 years (as the least) to 15 (as the maximum). The prevalence of late menarche was 1.1%. In addition, no early menarche was reported. There was no relationship between menarche age and economic status, birth order and number of children, but a significant relationship was ...

Objective To explore the independent role of age at menarche on menstrual abnormalities among adolescents. Methods The present study was a multicenter cross-sectional study on a large sample (n = 3782) of Italian girls aged 13-21 y attending secondary school who already had menarche. Girls were asked to fill in a questionnaire on menarcheal age and menstrual features during the latest three menses. The gynecological age was computed as the difference between age at the survey and the age at menarche. Main outcome measures were: prevalence of oligomenorrhea, polymenorrhea, menstrual cycle irregularity, abnormal bleeding length and dysmenorrhea. Irregularity in the recent past and since menarche was also studied. Multiple logistic models were used to identify any independent association between each abnormal feature and age at menarche or gynecological age. Adjusted ORs and 95%CI were performed. Results After adjusting for covariates, menarcheal age was not independently associated with polymenorrhea (OR = 0.81; 95%CI 0.63-1.04), oligomenorrhea (OR = 1.16; 95%CI 0.94-1.43), menstrual cycle irregularity (OR = 0.99; 95%CI 0.86-1.14), abnormal bleeding length (OR = 0.96; 95%CI 0.87-1.06) and dysmenorrhea (OR = 1.03; 95%CI 0.85-1.24). The multivariate analysis suggests that the higher prevalence of oligomenorrhea and menstrual cycle irregularity among the girls who were older at menarche might be purely explained by their younger gynecological age. Conclusions No evidence of any independent influence of age at menarche on menstrual abnormalities among young girls was shown by the investigation. The findings suggest that, after menarche, adolescent girls' menstrual health should be checked to monitor the endocrine system maturation and to early intercept latent disorders becoming symptomatic.
