Age Of Menarche

Aims: Menarche is an important milestone that signals the commencement of the reproductive life of the growing girl-child. The objectives of the study was to determine the age of menarche among the school girls, the relationship between age of menarche and anthropometric measurements, haemoglobin genotype, sporting activities and age of menarche of respondents’ mothers. Methods: This was a cross-sectional study carried out among selected secondary school students in Ilorin, Nigeria, between September 2008 and April 2009. Multistage and systematic random sampling techniques were used for subjects’ selection. Results: The mean menarcheal age of the respondents was 13.21 ± 1.29years while their mothers’ mean menarcheal age was 14.39± 1.82 years. Girls whose mothers have high level of education and of high social class attained menarche earlier than their other colleagues. The girls’ height, weight and body mass index had no significant influence on the age of menarche. The mean menarcheal age of girls with haemoglobin AA (13.25years) was lower than those with haemoglobin AS (13.79years) and haemoglobin SS (14.17years). The socioeconomic class was however, the only index that was significant on multivariate analysis. Conclusions: Girls are attaining reproductive capacity at a younger age and socioeconomic class was the most important variable that had relationship with age of menarche.

Age Of Menarche

Abstract Background There is strong evidence that the mean age of menarche has declined over the last few decades in developed and developing countries. This is of a major concern because of its enormous public health implications. This study aimed to estimate the age of menarche in Kuwait and investigate the association between menarcheal age and academic performance among high school girls in Kuwait. Methods A cross-sectional study was conducted on randomly selected female high school students from private and public high schools in all governorates in Kuwait. Data on the age of menarche were collected by self-administered questionnaire from the students, while data on academic performance were extracted from the students’ academic records. Results Of the 907 students we selected, 800 (88.2%) responded. The mean age of menarche was 12.33 [95% confidence interval (CI) 12.18–12.49] years. There was no evidence for significant association between age of menarche and students’ academic performance before or after adjusting for potential confounders. Conclusion The calculated age of menarche among contemporary girls in Kuwait is similar to that of the girls in industrialized countries. Early menarcheal age is unlikely to lead to adverse behavior that may affect academic performance in our setting.

Introduction: Sickle Cell Disease (SCD) is an inherited chronic haemolytic anaemia. The diseased person suffers from various complications such as anaemia, frequent infection, fever, hand-foot syndrome, stroke, etc. Puberty changes includes the appearance of the secondary sexual characteristics, increase in height, change in body composition and development of reproductive capacity. Aim: To study the sexual maturity and effect of multiple blood transfusions in adolescents suffering from SCD. Materials and Methods: It was a cross-sectional study conducted on 35 adolescents of age group 11 to 15 years, suffering from SCD. Study was conducted over a period of six months from March 2018 to September 2018 at Department of Paediatrics. SCD was diagnosed by Haemoglobin (Hb) electrophoresis. Weight and height were measured of all the participants. For assessing the sexual maturity, Tanners staging was used. Unpaired t-test was done for data analysis. Results: The mean age of the patients was 13.03±1.7 years. There were 25 males and 10 females. The mean age of male patients between Tanner stage 2(14.63±0.52 years) and Tanner stage 3 (14.75±0.5 years) was significantly higher than the Indian data for males (11.3 and 12.8 years, respectively). The mean age of female patients between Tanner stages 2 (13.5±2.12 years) and Tanner stage 3 (14.33±1.16 years) was higher than the Indian reference data for girls (10.2 and 11.6 years respectively). Conclusion: This study concluded that adolescents with SCD were significantly shorter in height and weight than the standard reference population. Sexual maturity is delayed in adolescents with sickle cell anaemia.

Abstract Background Menstrual disorders are common gynecological problems among adolescents, however, medical counseling for these disorders is not well documented in developing countries. Objectives This study aimed to assess medical counseling for menstrual disorders among schoolgirls in Beni-Suef city in South Egypt. Methods Using a multi-stage random sampling, a total of 970 preparatory schoolgirls were included in this study. We used a self-administered questionnaire to detect the premenstrual and menstrual disorders as reported by the schoolgirls during the previous 6 months. Medical counseling for the menstrual disorders and other demographic characteristics were also surveyed. Results The mean age of the schoolgirls was 15.4 ± 0.8 years, age of menarche 13.2 ± 1.1 years and menstrual flow days 5.0 ± 1.3. During the past 6 months, 19.4% of the schoolgirls reported medical counseling for at least one menstrual symptom. Dysmenorrhea (89.2%), premenstrual fatigue (32.4%) and headache (31.1%) were the most often reported symptoms. After adjustment for personal and gynecological characters, abdominal bloating [odds ratio (OR) 3.66; 95% confidence interval (CI) 2.18–6.17], flow days >4 (OR 1.73; 95% CI 1.21–2.47), acne flare (OR 1.42; 95% CI 1.01–1.99), dysuria (OR 2.09; 95% CI 1.35–3.22) and facial hair (OR 6.89; 95% CI 3.47–13.69) were associated significantly with a higher likelihood of medical counseling. Conclusion Menstrual disorders are highly prevalent among preparatory schoolgirls in Beni-Suef, however, there is a noticeable lack of the medical counseling for these disorders. Future research should focus on the barriers to medical counseling for menstrual disorders among adolescents.

Purpose: This paper examines the effect of boarding on obesity among middle school students at boarding schools. Design: Quantitative, cross-sectional study. Setting: Data from the China Education Panel Survey (CEPS) were analyzed. The CEPS samples middle school students from 7th grade to 9th grade in China. Subjects: The final sample included 3,892 observations of boarding school students. Measures: Measures included body mass index (BMI) that determined obesity, boarding status, demographic information, and instruments for boarding status. Analysis: The instrumental variables approach based on the 2 stage least squares (2SLS) methodology was utilized. The endogenous models and the extended probit models were also applied to the data to confirm the robustness of the results. Results: Boarding has a significant negative effect on obesity for middle school boys but a smaller negative effect on obesity for middle school girls. Boarding was estimated to reduce obesity by roughly 14% (p < 0.01) among middle school boys and 6% (p > 0.1) among middle school girls. The overall estimated effect based on the pooled sample was about 10% (p < 0.01). Conclusion: School or government policies that encourage boarding at school can reduce obesity among middle school students, at least for middle school boys. Boarding at school can be a positive factor in preventing and controlling obesity among middle school students.

Background: In the life of a female, menarche denotes the beginning of her reproductive capacity. Menstrual hygiene is an issue that every girl has to deal with in her life, but there is lack of awareness on the process of menstruation, the physical and psychological changes associated with puberty and proper requirement for managing menstruation.Methods: A cross-sectional study was conducted from October 2016 to December 2016 in the urban field practice area of SCB Medical College. One government high school and one private high school were selected purposively. A purposeful convenience sampling was done to select the girls who were studying in 8th, 9th and 10th standard. Data collected from 165 adolescent school girls using a predesigned, pretested and structured questionnaire. The objective of the present study is to assess the knowledge and practices regarding menstrual hygiene among school going adolescent girls and to know about the restrictions imposed upon them during menstruation.Results: Most of the adolescent girls (61.82%) had attained menarche between 13-15 years of age. 59.39% girls were aware about menstruation before menarche. The source of information about menstruation was the mother or elder sister in most of the girls (81.21 %), followed by teachers/friends in case of 18.79 % girls. 84.85% of the girls used only sanitary pad, 4.24% used only cloth and the rest 10.91% used both sanitary pad and cloth during menstruation.Conclusions: Maintenance of menstrual hygiene was better in private school girls as compared to government school girls. Health education sessions about menstrual hygiene should be conducted in the schools for spreading awareness regarding menstruation and menstrual hygiene.
