Abstract
BACKGROUND The relationship between the age at menarche (AAM) and the risk of intracerebral hemorrhage (ICH) and ischemic stroke (IS) is still up for debate. The purpose of this study was to investigate potential causal connections between them. METHODS Genome-wide association analysis (GWAS) of AAM conducted by the MRC-IEU consortium was utilized for association analyses of ICH and IS by two-sample Mendelian randomization (MR) study. AAM data of the within-family GWAS consortium were used as replication phase data to verify the causal relationship between each other. Inverse variance weighting (IVW) method was the primary method used in this MR study. For additional proof, the weighted median estimation, MR-Egger regression, MR-PRESSO test, and MR-Robust Adjusted Profile Score evaluation were performed. The Cochran's Q test and the MR-PRESSO global test were used, respectively, to examine the sensitivity and pleiotropy. Random effects meta-analysis was utilized to analyze the causal data from the two consortiums to further explore the causality between AAM and ICH, IS. RESULTS We found that the AAM was causally linked with the risk of ICH (OR = 0.48, 95% CI: 0.28-0.80, p = 0.006). On the contrary, the causal effect from AAM to IS (OR = 0.98, 95% CI: 0.91-1.06, p = 0.64) has not been confirmed. For all subtypes of ICH, we found that nonlobar intracerebral hemorrhage (NLICH, OR = 0.41, 95% CI: 0.23-0.75, p = 0.004) but not lobar intracerebral hemorrhage (LICH, OR = 0.65, 95% CI: 0.34-1.24, p = 0.19) was associated with AAM without surprise. Similarly, we used the within-family GWAS consortium data to explore causality and found that AAM may reduce the risk of ICH (OR = 0.78, 95% CI: 0.72-0.86, p = 9.5 × 10-8 ) and NLICH (OR = 0.68, 95% CI: 0.61-0.75, p = 3.4 × 10-13 ) by IVW methods, but is not related to IS (OR = 0.97, 95% CI: 0.93-1.02, p = 0.26). These findings are further supported by the meta-analysis. Both Cochran's Q test and the MR-PRESSO global test failed to detect the presence of sensitivity. CONCLUSION AAM and ICH, particularly NLICH, are causally related, but not LICH, IS, or its subtypes in European population.

Abstract
OBJECTIVES Age at menarche is a marker of pubertal timing that may influence adult height and body proportions. Previous studies have shown that socioeconomic status can affect age at menarche and growth patterns in different populations. This study aims to examine the associations between age at menarche, socioeconomic status, height, and leg length in a sample of Igbo ethnicity. METHODS The study used data from questionnaires and anthropometric measurements of 300 female students aged 18-25 years. Study tested the hypotheses that earlier menarche is associated with shorter stature and shorter leg length, and that these associations are modified by socioeconomic status using nonparametric analysis. RESULTS Mean age at menarche was fluctuating around 12.84 ± 1.40 and 13.59 ± 1.41 years with school girls and grew 3.0 cm taller per year birth cohort. The study also found that girls with earlier menarche were shorter adult height (162.51 ± 6.00) compared with girls who have menarche at a later age. The linear regression coefficients (bs) ranged from 0.37-0.49 in later year birth cohort and 0.37-0.44 in early year birth cohort for height. The effect of age at menarche on leg length was similar to the relation between age at menarche and birth cohort height. CONCLUSION The study will contribute to the understanding of how pubertal timing and socioeconomic status interact to shape adult health outcomes in a transitioning population.

Abstract
OBJECTIVE The aim: To investigate the peculiarities of menstrual cycle disorders in teenagers against the background of excessive stress in order to develop a scientifically based set of measures for their correction. PATIENTS AND METHODS Materials and methods: 120 girls aged 9-18 who were in the war zone or became forced migrants were examined. Examination methods included anamnesis collection, assessment of psycho-emotional state, anthropometry, laboratory and instrumental studies. RESULTS Results: It was found that the frequency of menstrual cycle disorders in the subjects was 65.8% (n = 79). Among menstrual cycle disorders: dysmenorrhea - 45.6% (n = 36), excessive menstruation - 27.8% (n = 22), secondary amenorrhea - 26.6% (n = 21). 71.7% (n = 86) of the examinees noted a change in eating behavior over the past few months. Almost half of these children had dyshormonal disorders or met the criteria of metabolic syndrome - 45.3% (n = 39). CONCLUSION Conclusion: Timely detection and adequate correction of psycho-emotional and metabolic disorders in adolescent girls in stressful conditions contributes to the prevention of disorders of menstrual and reproductive function.

Cohort-based analysis of maternal age at menarche in relation to young adult offspring anthropometric and metabolic parameters. Clin Endocrinol (Oxf) 2022; 97:293-302. [PMID: 34865241 DOI: 10.1111/cen.14642] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 10/18/2021] [Accepted: 11/06/2021] [Indexed: 12/17/2022]
Abstract
OBJECTIVES Age of menarche is a determinant factor of cardiometabolic risk, adiposity and stature at adulthood. However, little is known about the transgenerational effects of age of menarche, especially beyond childhood of any offspring, and the studies remain limited to anthropometric outcomes in children at birth or before adolescence. In the present study, we aim to investigate the relationship of maternal age at menarche (MAM) with anthropometric and metabolic parameters in the young adult offspring (aged 15-35 years) in a Persian population. DESIGN, PATIENTS AND MEASUREMENTS In this cohort-based cross-sectional study, we recruited 1139 mother-young adult dyads enroled in Rafsanjan Cohort Study (RCS) at adult RCS (aged 35-70 years) and youth RCS (aged 15-35 years) as part of the comprehensive PERSIAN (Prospective Epidemiological Research Studies in IrAN). In this study, MAM was categorized to early (MAM < 12 years), normal (12 ≤ MAM ≤ 14) and late menarche (MAM > 14 years). For these analyses, bivariate and multiple logistic regression models were used to investigate the relationships between late or early MAM and offspring anthropometric and metabolic parameters. RESULTS Early MAM displayed a significant association with an increased odds ratio (OR) of tall stature adjusting for sex, age, socioeconomic status index, maternal age at birth and maternal height (as genetically determined factor). Sensitivity analysis by sex indicated this relationship to be specific to male offspring only (adjusted OR: 1.84 95% CI: 1.13-3.00, p value: .014). In addition, late MAM displayed a significant association with reduced OR of overweight/obesity and abdominal obesity in daughters only (obesity adjusted OR: 0.49, 95% CI: 0.27-0.88, p value: .018, abdominal obesity adjusted OR: 0.44, 95% CI: 0.23-0.82, p value: .010). dose-response analysis by categorization of MAM, further supported our results. On the contrary, our analyses do not support a significant relationship between MAM and youth metabolic indices, that is, metabolic syndrome, fasting blood sugar (FBS), high-density lipoprotein (HDL) and triglyceride (TG). CONCLUSIONS The results of the present study indicate an association of maternal age of menarche with anthropometric measures of offspring in young adulthood in a sex differential manner. The data does not support a significant relationship between the metabolic indices FBS, TG and HDL in offspring with MAM. Overall, this study provides evidence for the intergenerational effects of age at menarche in the development of anthropometric measures in offspring in young adulthood (15-35), which is the first study of this kind in this age range.

Associations of maternal age at marriage and pregnancy with infant undernutrition: Evidence from first‐time mothers in rural lowland Nepal. AMERICAN JOURNAL OF BIOLOGICAL ANTHROPOLOGY 2022.

Abstract
Objectives Maternal factors shape the risk of infant undernutrition, however the contributions of age at marriage versus age at pregnancy are rarely disentangled. We explore these issues in a population from lowland rural Nepal, where median ages at marriage and first pregnancy are 15 and 17 years respectively and marriage almost always precedes pregnancy. Methods We analyzed data on first‐time mothers (n = 3002) from a cluster‐randomized trial (2012–2015). Exposures were ages at marriage and pregnancy, categorized into groups. Outcomes were z‐scores for weight (WAZ), length (LAZ), head circumference (HCAZ), and weight‐for‐length (WLZ), and prevalence of wasting and stunting, for neonates (<8 days) and infants (6–12 months). Mixed linear and logistic regression models tested associations of marriage and pregnancy ages with outcomes, adjusting for parental education, household assets, caste, landholding, seasonality, child sex, intervention arm, randomization strata and cluster. Results For neonates, pregnancy <18 years predicted lower LAZ, and <19 years predicted lower WAZ and HCAZ. Results were largely null for marriage age, however early pregnancy and marriage at 10–13 years independently predicted neonatal stunting. For infants, earlier pregnancy was associated with lower LAZ and HCAZ, with a trend to lower WAZ for marriage 10–13 years. Early pregnancy, but not early marriage, predicted infant stunting. Conclusions Early marriage and pregnancy were associated with poorer growth, mainly in terms of LAZ and HCAZ. Associations were stronger for neonatal than infant outcomes, suggesting pregnancy is more susceptible to these stresses. Early marriage and pregnancy may index different social and biological factors predicting child undernutrition.

Abstract
OBJECTIVES The minimum body mass index (BMI) required to menarche and the relationship between the training onset age of sports and menarche is not fully understood. The aim of this study is to elucidate the minimum BMI required to attain menarche in female adolescent athletes competing at a national level, and to determine how the occurrence of menarche is associated with training onset age in track-and-field athletes. METHODS Overall, 134 sprinters and 44 long-distance (LD) runners of ninth-grade females at a national level were enrolled and an anonymous questionnaire was administered. RESULTS As BMI increased, the proportion of athletes who had attained menarche increased. The BMI cutoff values for menarche were 17.3 and 17.1 kg/m2 for sprinters and LD runners, respectively. Menarche had not occurred in almost 50% of the LD runners who began training at elementary school, and among LD runners, those who began training at elementary school had 18.4 higher odds of not attaining menarche until the age of 15 years as opposed to those who started training after elementary school. CONCLUSIONS The BMI cutoff values could be an indicator for menarche in sprinters and LD runners. For LD runners, starting to compete at elementary school could be a risk factor for delayed menarche.

Abstract
Menstruation is a natural process in girls, but sometimes it is accompanied by beliefs and behaviors with cultural roots that result in poor health consequences; this study aimed to consider perceptions of individual, families and community to current cultural beliefs, and to determine the effect of education based on the PEN-3 cultural model on students' menstrual health behaviors in Iran. Study had a mixed method design. In the qualitative phase, data were collected from students, their mothers and teachers through focused group discussion and in-depth interviews. In the quantitative phase, training was done in four 2-h sessions for intervention group. The data were collected immediately and 2 months after the training by a questionnaire and they were analyzed by Friedman and Wilcoxon non-parametric tests. Training was effective on all of the model structures and significantly increased mean score of the health behavior after training and 2 months later by 8.74 and 13.86, respectively, in intervention group (P<0.05). The perception and behavior of the others and access to sanitary services and products, especially cultural factors affect girls'' menstrual health behaviors, therefore, it is necessary to design the health plans regarding each of these factors, and the cultural context of each community.

Abstract
INTRODUCTION Onset age at menarche has been considered an important indicator of reproductive maturity in females and reflects the health status of the population. The purpose of this study was to determine the mean menarcheal age and to examine whether anthropometric and socio-economic status (SES) influences age at menarche in the girls from Punjab province of Pakistan. METHODS In this population-based cross-sectional study, 10,050 school-going girls aged 8-16 years from 35 schools across 12 districts of Punjab were recruited. Menarcheal data was obtained by using a questionnaire, while the anthropometric data were obtained by the measurements of standing height, body weight, waist, and hip circumference. The anthropometric indices of pre- and post-menarcheal girls were compared. Student's t-test, ANOVA, and post-hoc Tukey's test was applied for comparison between two and multiple groups respectively, P < 0.05 was considered statistically significant. RESULTS There was a normal distribution of age at menarche and mean was 12.4 years in the study population. The girls who reached menarche were found to be taller and heavier with higher BMIs, having a greater waist and hip circumference as compared to their pre-menarcheal peers. Waist-hip-ratio was less, and the waist-to-height ratio was higher in post-menarcheal as compared to pre-menarcheal girls. The girls belonging to low SES had delayed onset of menarche as compared to those belonging to middle/high SES. CONCLUSION The age at menarche was associated with SES and changes in various anthropometric measurements reflecting the growth status of girls.
