Age Of Menarche

INTRODUCTION: In this study, we aimed to determine the range of mean age at onset of menarche (AOM) and puberty (AOP) of girls living in Aydin province and to determine the factors affecting the onset age of menarche. METHODS: A total of 1891 girls aged between 8 and 16 years attending primary, secondary and high schools in Aydin province were planned to be included in the study. A questionnaire that was prepared in line with the literature was delivered to the parents in a closed envelope. The subjects who accepted to participate in the study were examined by an experienced physician by measuring height and weight and pubertal status was defined according to Tanner scale. BMI values were calculated. RESULTS: In total, 1520 female students were accepted to the study with the permission of their families. The mean AOM of participants was 12.11±1.32 years. The mean AOM was 13.12±1.46 years for their mothers, and 12.73±1.25 years for their sisters. June was the month that menarche occurred most frequently. We observed that the children living in rural areas had an earlier age of menarche. The mean age at onset of puberty was 9.71±1.46 years. DISCUSSION AND CONCLUSION: Our study is important in terms of being the first study conducted in Aydin province that determined the mean AOM and AOP of girls aged between 8 and 16. In our study, we showed that the age of menarche shifted to an early age, while the age of puberty did not shift. The age at onset of menarche and puberty were similar to the results obtained in other studies conducted in neighboring regions. We believe that larger scale studies may contribute to assess the actual mean age at menarche of girls living in Turkey.

Hormones, life style, animal proteins etc are factors that influence menarche. Like-wise a declining trend in age at menarche has been noticed over the past few years. This study was taken up with the objectives to study factors that are associated with menarche in our study population. Hence a school-based cross-sectional study was undertaken for the same which showed the mean age of menstruation was 12.5 years. It was significantly influenced by milk intake (p <.05). Mothers’ age at menarche was also found to be significantly associated with their daughters’ age at menarche. Conclusion: This study provides an insight into determining factors affecting age of menarche, focusing on dietary and maternal factors. Milk consumption was found to be an important factor.

AbstractBackgroundMenarche age has been associated inconsistently with the occurrence, timing or severity of major depressive disorder (MDD), but rarely studied in women with bipolar (BDs) or anxiety disorders.MethodsWe investigated women patients at a Sardinian mood disorder center for associations of age at menarche with age at illness onset for major affective or anxiety disorders, year of birth, and other selected factors, using bivariate comparisons and multivariate regression modeling.ResultsAmong women (n = 1139) with DSM-IV MDD (n = 557), BD-I (n = 223), BD-II (n = 178), or anxiety disorders (n = 181), born in 1904–1998, of mean age 42.9 years, menarche age averaged 12.8 [CI: 12.7–12.9] years. Illness onset age averaged 30.9 [30.1–31.8] years, ranking: BD-I, 25.8; anxiety disorders, 28.0; BD-II, 30.3; MDD, 34.1 years. Menarche age declined secularly over birth years, and was associated with younger illness-onset, having no or fewer siblings, more psychiatrically ill first-degree relatives, living in rural environments, being suicidal, substance abuse, and being unemployed. Earlier menarche and earlier illness-onset were significantly associated for onset age groups of ≤ 20, 20–39, and > 40 years. Menarche age versus diagnosis ranked: BD-II < BD-I < anxiety disorders < MDD.ConclusionsAge at menarche in Sardinia, as elsewhere, has declined over the past decades. It was strongly associated with age at onset of bipolar and anxiety, as well as major depressive disorders across the age range, suggesting sustained effects of biological maturational factors.

The present study was designed to determine the age at which menarche occurs among school girls in Buldana district of Maharashtra state, India. A survey was conducted among 488 girls by writing the questionnaire from schools in the selected area. Respondents completed a questionnaire that recorded age at first menstruation by the recall, residential status, type of education, and diet/food habit. The mean age at menarche was 13.44 ± 0.75 years. Most girls (72.95%) of the respondents were found of normal age menarche (12–14 years), 27.05% of late-type menarche (> 14 years), and 0% were of early menarche (less than 12 years). Our study suggests an influence of school education, residential area, and diet/food habit on menarcheal age.

Introduction: Menopause simply refers to the time when a woman stops having monthly period. There have been numerous systematic studies into the age at onset of menopause and the factors affecting it, in different parts of the world. However, the establishment of this age and factors affecting it in Rivers state has been scanty. Aim: This research was therefore undertaken to ascertain the age at onset of menopause in women of Rivers state, residing in Port Harcourt and the effect of parity, age at last child birth and form of birth control on it. Methodology: This study used data from over 380 postmenopausal women from populations in Port Harcourt, Rivers state. Different ages specified by the respondents through structural questionnaires were used. The data was collected and analyzed using the ANOVA method. It was used to obtain a percentage frequency which was presented in a table. Results: The result shows the mean menopausal age among Rivers state women to be 49.1 years. It was also found that menopausal age was affected by subjects’ parity, age at last child birth and form of birth control. Conclusion: The mean menopausal age of women of Rivers State, living in Port Harcourt has been found to be 49.1 years. This age has also been found to be positively affected by a woman’s parity, age at last child birth and form of birth control.

The study was conducted as descriptive-sectional to investigate the age of menarche and the influencing factors of female students studying in the preparatory class of a state university. The universe of this research was the female students between February 2014-May 2015 in school of foreign languages at a state university. The study was held with all universe instead of sampling selection. 738 female students were voluntary participated into the study. Data were collected by the survey form. The menarche age of the participants is 13,3±1,12 (10-17) years old, and there is statistically significance between menarche age and body mass index (p<.001). The other statistically significance was available between menstrual period and weight change (p<.05). It has been found that the menarche age decreases as the students’ weight and BMI increases and the duration of the menstruation cycle increases. Factors affecting students’ menstruation order were investigated and it was determined that only weight change affects menstruation order. In the study, significant results were found between body mass index and age of menarche.

Age Of Menarche

 Introduction: In Bhutan, pubertal and adolescent female students (10-19 years) make up 8.5% of the population. The need for menstrual hygiene management (MHM) is more urgent in post-menarcheal female students and in resource-poor settings. However, until recent time, there were strong socio-cultural barriers to discourses on menarche and MHM. This study was conducted to determine the age of menarche among Bhutanese female students to identify when to offer MHM support, their knowledge on menstruation and practices related to menstrual hygiene. Methods: This was a cross-sectional survey of female students studying in Grade 10 in Thimphu, Bhutan. A multistage clustered sampling was used. Data was collected using a self-administered questionnaire developed for the purpose of this study. Results: A total of 439 post-menarcheal female students were interviewed. The mean age of menarche was 12.8±1.1 years, and fear (38.3%) and confusion (25.1%) were the commonest responses. The mean score on knowledge on menstruation and MHM was 5.9±1.5 out of 9. The proportion of students with good knowledge was 36.7%. The common sources of information were the mother, teacher, and sister. The majority used commercial pads (92.5%) while some used clean cloths (5.7%) and tampons (1.6%). The proportion who stayed absent from school during menstruation in the month prior to data collection was 9.8%. Visiting religious places (67.6%) and participating in sports (4.3%) were common restrictions during menstruation. Conclusions: Female students experience difficulties in menstrual hygiene management in schools. Menstruation could lead to missing schools and other activities.  Keywords: Developing country; Health behaviour; Menstrual hygiene product; Standard of living.

SummaryEarly onset of menarche has been shown to be associated with breast cancer and ischaemic heart disease. Studies on age at menarche of the Malaysian population are poorly documented. This study aimed to determine the influence of anthropometric and socio-demographic factors on the age at menarche of university students in Malaysia. Data were obtained in 2010–11 from 961 students between the ages of 18 and 25 years from the University of Malaya using stratified sampling, and multiple regression analysis was applied. Sixty-three per cent of students reached menarche at the age of 12 or 13 years, with the mean and median of age at menarche being 12.45±1.17 and 12.01 years, respectively. Menarcheal age was positively associated with height (p<0.05) and negatively associated with BMI (p<0.001). Students from urban areas attained menarche earlier than those from rural areas (p<0.05). Students from small-sized families attained menarche earlier than those from larger families (p<0.05). First-born students experienced menarche earlier than those who were seventh-born or later. Obese and overweight students reached menarche earlier than students who were underweight or of normal weight (p<0.01). The variations in age at menarche among the Malaysian ethnic groups were statistically insignificant. The results suggest that heavier and first-born students from small families are more likely to attain menarche earlier than their counterparts.

Age Of Menarche

INTRODUCTION : Various studies indicate that the average age of menarche has decreased significantly in the last 150 years, which there has been a secular (time-related) trend towards an earlier onset of menarche in most developed countries. In recent years, such a decline has also been observed in developing countries like India. The purpose of the present study was to asses the effect of food and social status on age of menarche in this region. METHODS: Study included 200 girls of age group between 9 to 14 on Voluntary basis after Simple Random Sampling around the schools . After obtaining permission and consent from the school Principal/ class teacher, a predesigned questionnaire was administered and girls were briefly examined by a female doctor. . Detail information about girls and their parents were taken to know the mother’s age at menarche and also to know the socioeconomic status of the family along with other details. RESULTS: Our study shows that age at menarche in higher socioeconomic classes is lower as compare to Lower Socioeconomic class. No significant association between BMI & type of food and average age of menarche was found in our study. CONCLUSIONS: The trend of lowering of age at menarche is well marked as we moved from lower and middle to higher socioeconomic stratum. There is paucity on such data from this region of India; hence further study needs to be done among girls from other areas of the state before the data can be extrapolated to the Indian statistics.

This study aimed to estimate the willingness of households to pay for domestic clean water use against its price in rural areas of Cang Long district, Tra Vinh province. This research also identified the possibility and factors affecting the willingness to pay for a given price of 6,500 VND or above per m3 of clean water. A contingent valuation method with multiple prices (bidding game) ranging from VND 5,000 to VND 9,000 per m3 of clean water was applied to interview 120 households in Cang Long district. Results showed that the mean willingness to pay was VND 6,200 for each m3 of clean water used. The income positively affected the willingness to pay against the price of 6,500 VND or above whereas the household size had a negative impact on this parameter. It is suggested that the service provider should consider to extent the minimum volume of water used up to 10 m3/month instead of 4 m3/month in accordance with the minimum price of 5,700 VND per m3 of water used.
