Timing Of Menarche

Abstract Background Studies about the majority of the factors that may potentially influence the pubertal timing and menarche were controversial. The objective was to evaluate the association between factors related to the pregnancy, neonatal period, and the complications that may happen later in life and the menarcheal age in a sample of Lebanese girls admitted or not to the NICU at birth. Our secondary objective was to try to find, for the first time in literature, a correlation between respiratory distress at birth and the need of oxygen therapy with the age of the first menses in these girls. Methods It is a cross-sectional retrospective study, conducted between January and March 2019. Our sample included all the 2474 girls born in Notre-Dame-de-Secours hospital, between 2000 and 2005; the sample consisted of 297 girls (97 girls admitted to the NICU and 200 randomly chosen to participate in our study with a ratio of 1:2 (1 girl admitted to the NICU vs 2 girls born in the nursery). Results Asthma later in life was significantly associated with lower age at menarche in girls, whereas a higher mother’s age at menarche and a higher gestational age were significantly associated with higher age at menarche in girls. When taking each cause of NICU admission as an independent variable, showed that a higher mother’s age at menarche was significantly associated with higher age at menarche in girls, whereas a higher number of days of phototherapy, a preeclampsia in the mother during pregnancy and asthma later in life in the girl were significantly associated with a lower age at menarche in girls. Conclusion The timing of menarche seems to be associated with many factors in Lebanese girls that should not be disregarded by physicians.

Menarcheal Age

AbstractA first menstrual bleeding (is called menarche), as one of the sign of puberty, is veryimportant event in the reproductive life of a woman. Age at menarche is affected by twomajor factors/determinats, genetic and non genetic (environmental), reflects the healthstatus of a population. In recent years, the average age at menarche showed acontinuous trend for earlier, although this trend tends to slow down or stabilize. EarlyAAM may be associated with social and medical problems in later life. This study wasdesigned to determine the relationship of mothers age at menarche and their postmenarchealdaughters at grades 5 and 6 in three Pucangan public elementary schools(SD Negeri I, III, IV Pucangan). Similarity of Elementary School’s location (in thePucangan Village), have a tendency in common areas of residence, socioeconomicstatus, and other non-genetic determinants, so the researchers wanted to know therelationship between menarcheal age of mothers and their daughters.Subject were 31 female students at grades 5 and 6 in SD Negeri, I, III, IV Pucangan,District of Kartasura Sukoharjo. The sampling technique to be used is saturated samplinginwich all of the population to be used as sample.This cross sectional study used Pearson correlation test (with α = 0.05) to analyze dataand obtained p value of 0.402 to p > 0.05 which means that Ho : accepted and Ha :rejected. The result showed that there was no relationship between menarcheal age ofmothers and their daughters at grades 5 and 6 in SD Negeri I, III, IV Pucangan, District ofKartasura Sukoharjo.Keywords : Menarche, Age at Menarche, Genetic Determinants

Background: Studies have shown trends of decreasing age at menarche in most of the Indian states. However, there are no such studies reported from the state of Sikkim.Methods:It was a cross sectional prospective study done in four school across Gangtok town. 430 menstruating girls between the age group 10-19 years were the participants. Data regarding chronological age, menstrual age, diet, mother’s age at menarche and socioeconomic status was collected using self-administered pre-tested questionnaire from the girls and their parents. Height, weight and general physical examination of the girls were done.Results: Mean age of attainment of menarche was 12.52 years. 3% girls were undernourished and 20.70% girls had their body mass index more than 85th percentile. A positive correlation between age of onset of menarche with height (r = 0.282), weight (r = 0.130) and mothers age at menarche (r = 0.549) and negative correlation with body mass index (r = -0.155). Menarche was earlier in girls belonging to lower socioeconomic classes (P <0.001). Peak incidence of menarche was noticed in winter months in this hilly area. Diet, ethnicity and sibling order did not show statistically significant effect.Conclusions:The mean age of menarche in this region is comparable to many Indian states. The major determinant of age at menarche in this study was body mass index and mother’s age at menarche similar to other Indian and international studies. Further similar studies on girls from other parts of Sikkim are needed for scientific data.

Timing Of Menarche

AbstractAssociations have been shown between father’s absence and menarcheal age, but most studies have focused on absence resulting from divorce, abandonment or death. Little research has been conducted to evaluate the effect on menarcheal age of paternal absence through migrant work. In a sample of 400 middle school students, this study examined the association between paternal migrant work and menarcheal age against a backdrop of extensive rural-to-urban migration in China. Data were collected through a self-reported questionnaire, including social-demographic characteristics, aspects of family relationships, information about father’s migrant work and age at menarche. After adjusting for BMI, parent marital status and perceived relationship with mother, lower self-perceived quality of father–daughter relationship (both ‘father present, relationship poor’ and ‘father absent, relationship poor’) and lower frequency of contact with the father were associated with higher odds for early menarche. These findings suggest that the assumption that father’s absence for work influences the timing of menarche needs to be examined in the context of the quality of the father–daughter relationship and paternal care, which appear to play a critical role in the timing of menarche. These findings also emphasize the importance of enhancing paternal involvement and improving father–daughter relationships in the development of appropriate reproductive strategy in daughters.

Management Behaviors

Purpose: To assess the association between growth and maturation with weight management behaviors (WMBs) among Mexican American youth. Design: A cross-sectional design was used to measure timing of growth and maturation as well as WMBs. Sample: Students were recruited through physical education classes in south Texas schools. The sample included 623 participants (52.3% female; 49.8% with weight ≥85th percentile) in grades 4 through 12. Students in middle school were purposely oversampled to examine questions around timing of growth and maturation. Measures: Growth was measured as maturity offset, an estimate of age at peak height velocity (PHV). Maturity offset is derived from chronological age, height, and sitting height measurements. Participants were classified as pre-PHV or post-PHV. Girls also were categorized as premenarche or early, average, or late maturing based on age at menarche. Weight was measured to calculate body mass index (BMI) percentile. Weight management behavior and timing of menarche were self-reported via a survey. Analysis: Descriptive characteristics were calculated for boys and girls separately. χ2 Tests of proportion were used to test WMB by BMI percentile. Logistic regression analyses were conducted to examine the likelihood of engaging in WMB by maturity offset and, for girls, timing of menarche. Results: Students with weight ≥85th percentile were more likely to describe themselves as overweight and report trying to lose weight through exercise or calorie restriction ( P < .0001). A 1-year increase in maturity offset was associated with youth being 31% more likely to perceive themselves as overweight but less likely to report calorie restriction (odds ratio [OR] = 0.87). Average maturing girls were more likely than premenarcheal girls to exercise, restrict calories, or fast to lose weight (OR = 3.27, 2.11, and 3.27, respectively). Conclusion: Mexican American youth are engaging in WMB, even when their weight status is <85th percentile. The appropriateness of weight management counseling may need to consider a child’s stage of growth.

Abstract STUDY QUESTION Is pubertal timing associated with risk of premenstrual disorders (PMDs) in young adulthood? SUMMARY ANSWER Late pubertal development is associated with decreased premenstrual symptom burden and risk of PMDs in young adulthood. WHAT IS KNOWN ALREADY PMDs, including premenstrual syndrome and premenstrual dysphoric disorder, may begin during the teenage years. Few risk factors in early life have been identified for PMD development. STUDY DESIGN, SIZE, DURATION A prospective cohort study of 6495 female participants during 1996–2013. PARTICIPANTS/MATERIALS, SETTING, METHODS We included participants from the Growing Up Today Study (GUTS). Pubertal development was indicated by the timing of menarche, breast and pubic hair growth. Self-reported age at menarche was longitudinally assessed at enrollment (in 1996/2004 for GUTS I/II) and onwards, and classified as early (age ≤ mean − SD, 11.64 years), normative and late menarche (age ≥ mean + SD, 13.95 years). Timing of pubic hair and breast growth were assessed multiple times during follow-up via Tanner scales, and classified into early, normative and late development according to mean ± SD. Using a validated questionnaire based on the Calendar of Premenstrual Experiences, we assessed premenstrual symptoms and identified probable cases of PMDs in 2013. We examined the associations of timing of pubertal development with premenstrual symptom score and disorders using multivariable linear and logistic regressions, respectively. MAIN RESULTS AND THE ROLE OF CHANCE In 2013 (mean age = 26), 1001 (15.4%) individuals met criteria for a PMD. An inverse association was found between age at menarche and premenstrual symptom z-score (β −0.05 per year, 95% CI −0.07 to −0.03) and risk of PMDs (odds ratio (OR) 0.93 per year, 95% CI 0.88 to 0.99). Compared to individuals with normative menarche, individuals with late menarche had a lower risk of PMDs (OR 0.73, 95% CI 0.59 to 0.91), while individuals with early menarche had comparable odds (OR 0.98, 95% CI 0.81 to 1.18). Moreover, early growth of pubic hair was associated with increased premenstrual symptoms (z-score β 0.09 per year, 95% CI 0.02 to 0.17) and PMD risk (OR 1.28, 95% CI 1.04 to 1.56), independent of age at menarche. No associations were noted for breast development. LIMITATIONS, REASONS FOR CAUTION One major limitation is some misclassification of menarche due to recall. We, however, showed robust association among participants who were premenarcheal at baseline. WIDER IMPLICATIONS OF THE FINDINGS Our findings suggest that pubertal timing, particularly timing of menarche, is inversely associated with the risk of developing premenstrual symptoms in young adulthood, and that women with later menarche have significantly lower risk of PMDs. Information on PMDs should be provided to teenage girls and their parents. If these findings are confirmed in independent populations, prevention strategies and early detection programs may be considered for women with early pubertal development.

Purpose: This study utilized data from the Korean National Health and Nutrition Examination Survey (KNHANES) to explore differences in the timing of menarche in Korean girls according to blood heavy metal concentrations.Methods: This study performed a secondary analysis of cross-sectional data from the sixth KNHANES. Data from 179 female children and adolescents aged 10~18 were included in this study. The relationships of blood heavy metal concentrations (lead, mercury, and cadmium) with age of menarche were analyzed using complex sample multiple logistic regression.Results: In the participants of this study, the geometric mean values of blood lead, mercury, and cadmium concentrations were 1.15±0.04 μg/dL, 1.80±0.08 μg/L, and 0.30±0.03 μg/L, respectively. Mercury poisoning (>5 μg/L) was found in 1.5% of participants. Furthermore, significant relationships were found between blood lead and mercury concentrations and age at menarche (<i>p</i> for trend: <i>p</i><.001 and <i>p</i>=.015, respectively).Conclusion: Through an analysis of national big data, this study found evidence that Korean girls showed a younger age at menarche in response to higher blood lead and mercury concentrations. To prevent and manage precocious puberty in Korean children and adolescents, a systematic policy that monitors both exposure to environmental hazards and blood heavy metal concentrations is needed.

Menarcheal Age

Aims and Objectives: Increase of childhood obesity prevalence and rapid changes in socio-economic status resulted in a decline in age at menarche, which contributes, to a number of diseases affecting women’s future health. The objective of this study is to assess the mean age at menarche in girls of ages 9-16 and observe its relationship with their body mass index and other covariates in Riyadh, Saudi Arabia.Materials and Methods: A cross-sectional study was conducted among 304 female students of both private and governmental schools in Riyadh, Saudi Arabia, during March –May 2013. Data on demographics, socioeconomic status, physical activity, diet, and age at menarche were collected from students and their mothers, using self-administered questionnaires. Physical examinations were conducted to collect the anthropometric measurements. Results: Out of 304 students with a mean age (SD) of 12.52(2.08), 165 (54.3%) attained menarche. Mean menarcheal age (SD) for the girls was 12.08 (1.28). The mother’s mean age at menarche was positively correlated with their daughters (r=0.411, P<0.001). There was no significant correlation between BMI and age at menarche (P>0.05).  Governmental school students attained menarche at a higher age (12.34) than private school students (11.59), and the difference between them was statistically significant (P<0.001).Conclusion: Schoolgirls in our study attained menarche at an early age with a mean menarcheal age of 12.08 years. Our data follows the globally and regionally observed declining trends of age at menarche. When assessing BMI as an influencing factor of onset of menarche, our results showed no correlation. Further longitudinal studies are encouraged to monitor factors influencing the onset of menstruation, in order to prevent the potentially adverse consequences of early menarche.Asian Journal of Medical Sciences Vol.7(2) 2015 5-12

Fetal Compromise

Background: Emergency LSCS can be categorized based on RCOG guidelines into category I and II which indicates maternal or fetal compromise. Here an urgent delivery and the DDI (decision to delivery interval) within 30 and 45 minutes respectively is needed.Methods: This is a retrospective cross-sectional analysis conducted on a sample of 630 patients who underwent caesarean section over a year, from June 2016 to June 2017. The DDI were further classified into ≤30 and >30 minutes for category I, ≤45 and >45 minutes for category II LSCS. The primary objective is to determine whether DDI in Category I and II emergency LSCS has an impact on fetal outcome and secondary objective is to ensure that DDI is within the standard criterion as per RCOG protocol.Results: Out of 630 samples of caesareans, it was found that 173 falls in Category I and 189 falls in Category II. Out of 87 (50.29%) patients delivered within 30 minutes in Category I, 29 babies required NICU admission. DDI was more than 30 minutes in 86 (49.71%) cases in Category I out of which 38 babies got admitted in NICU with low APGAR scores. Out of 176 (93.12%) patients who delivered within 45 minutes in Category II, 56 babies required NICU admission. DDI was more than 45 minutes in 13 (6.88%) cases in Category II and all these babies got admitted in NICU.Conclusions: Decision -delivery interval has a significant impact on fetal outcome.

SummaryThe present cross-sectional research was designed to study possible correlations between clinical reproductive factors and bone mineral density (BMD) values.Using the data gathered by the population-based Iranian Multicenter Osteoporosis Study (IMOS), we investigated the correlation found between reproductive factors and osteoporosis. Subjects were recruited from five major cities of Iran. Bone mineral density was measured using Dual-Energy X-ray Absorptiometry and the results were analyzed against the age at menarche and at menopause, number of pregnancies, children and abortions, and the history (and duration) of breastfeeding.Data was available for 2528 women. Gravidity and number of children were reversely correlated with BMD. Younger age at menarche was associated with higher BMD values, whereas there was no significant correlation between age at menopause and menstrual history and BMD.Our study suggests that clinical reproductive factors, particularly number of children and breastfeeding, could be incorporated as predictors of BMD levels in women. Given the controversial results obtained in different studies, longitudinal studies should be carried out to enlighten the importance of these factors and the rationale of their use to predict BMD values in different settings.
