Age at menarche and depression at the age of 31 years: findings from the Northern Finland 1966 Birth Cohort Study

Gonadal and adrenal hormones interact with pubertal maturation to predict depressive symptoms in a group of high-school females

Adolescent females are at elevated risk for the development of depression. In this study, we addressed two questions: Are pubertal hormones associated with adolescent mental health? Might this association depend on pubertal development? We tested the hypothesis that estradiol, which has been associated with adolescent social sensitivity, might interact with pubertal stage to predict depression risk at three time points in ninth and tenth grade. Hormones and pubertal development were measured ninth-grade females. Linear regression analyses were used to predict fall ninth-grade (N = 79), spring ninth-grade (N = 76), and spring tenth-grade (N = 67) Children's Depression Inventory (CDI) scores. The hypothesized model was not statistically significant, but exploratory analyses revealed that two- and three-way interactions incorporating estradiol, puberty (stage and perceived onset), and cortisol predicted current and future CDI scores. Our exploratory model did not predict changes in CDI but did account for future (spring of ninth grade) CDI scores. Specifically, estradiol was positively correlated with fall and spring ninth-grade depressive symptoms in participants with high cortisol who also reported earlier stages and later perceived onset of pubertal development. These findings suggest that hormones associated with sensitivity to the social environment deserve consideration in models of adolescent depression risk.

Age at menarche and depression: results from the NHANES 2005-2016

Objective

The association between early age at menarche and depression among adolescent girls and adult women has been examined in many studies. However, inconsistent results and limitations such as small sample size, low generalizability, and measurement error exist. We aimed to address these issues to assess the association between age at menarche and depressive symptoms in a nationally representative sample of US women aged 18 years and older.

Methods

We used the 2005–2016 National Health and Nutrition Examination Survey (NHANES) data with a total of 15,674 women aged 18 years and older included in our study. Logistic regression models were used after adjusting for sociodemographic and health-related factors.

Results

The crude-adjusted model suggests that women with early age of menarche had 1.36 (95% CI [1.16–1.61]) times the odds of current depressive symptoms compared with the normal menarche group, after controlling for age, race/ethnicity, education, poverty income ratio (PIR) and marital status. In the fully-adjusted model, women with early menarche had 1.25 (95% CI [1.05–1.48]) times the odds of current depressive symptoms, after additionally adjusting for smoking status and body mass index (BMI). However, no significant difference was observed between the normal and late menarche groups.

Conclusion

Further studies are warranted to determine the causal relationship and mechanisms between early menarche and increased risk of depression.

Assessment of menopausal symptoms in different transition phases using the Greene Climacteric Scale among rural women of North India

BACKGROUND

Menopause is the universal physiological process of women's midlife and exhibits a wide variety of symptoms. However, there is little data on the menopausal symptoms and factors associated with their severity among rural Indian women.

AIM

To evaluate the prevalence of menopausal symptoms during the different transition phases of menopause among rural women of North India.

SUBJECTS AND METHODS

This cross-sectional study consisted of 351 women aged 35-55 years (mean age 44.6 years) residing in rural areas of North India. A structured questionnaire was used to collect data regarding menopausal status, demographic profile and reproductive history of the participants. Frequency and severity of menopausal symptoms were evaluated using the Greene Climacteric Scale in different stages of menopause. All statistical procedures were accomplished using SPSS version 19.0.

RESULTS

In the present study the mean ages of attainment of menarche and menopause were 14.3 years and 47.2 years, respectively. Mean score of total Greene Climacteric Scale was highest among perimenopausal women (16.12 ± 8.1) over post-menopausal (14.78 ± 7.3) and pre-menopausal women (11.08 ± 6.1). Logistic regression analysis revealed that advancing age, low educational attainment, low socioeconomic status, menopausal status, later age at menarche and higher BMI were all associated with more severe menopausal symptoms.

CONCLUSION

The climacteric symptoms were more prevalent among women who were perimenopausal followed by post-menopausal women and were the lowest in pre-menopausal women. Age, menopausal status, socio-economic status, and reproductive factors significantly influenced the severity of menopausal symptoms.

Association of timing of menarche with depressive symptoms and depression in adolescence: Mendelian randomisation study

BACKGROUND

Observational studies report associations between early menarche and higher levels of depressive symptoms and depression. However, no studies have investigated whether this association is causal.

AIMS

To determine whether earlier menarche is a causal risk factor for depressive symptoms and depression in adolescence.

METHOD

The associations between a genetic score for age at menarche and depressive symptoms at 14, 17 and 19 years, and depression at 18 years, were examined using Mendelian randomisation analysis techniques.

RESULTS

Using a genetic risk score to indicate earlier timing of menarche, we found that early menarche is associated with higher levels of depressive symptoms at 14 years (odds ratio per risk allele 1.02, 95% CI 1.005-1.04, n = 2404). We did not find an association between the early menarche risk score and depressive symptoms or depression after age 14.

CONCLUSIONS

Our results provide evidence for a causal effect of age at menarche on depressive symptoms at age 14.

Puberty and perimenopause: reproductive transitions and their implications for women's health

This scoping review synthesizes existing research on two major transitions in females' lives: puberty and perimenopause. These two periods of vast physiological change demarcate the beginning and the end of the reproductive life cycle and are associated with major neuroendocrine reorganization across two key systems, the hypothalamic-pituitary-gonadal (HPG) axis the hypothalamus-pituitary-adrenal (HPA) axis. Despite growing evidence suggesting that the timing and experience of puberty and perimenopause are related to various physical and mental health outcomes (e.g., mood disorders, metabolism, cardiovascular health, autoimmune conditions, and cancer), these two processes are rarely examined together. In this paper, we bridge these disparate literatures to highlight similarities, isolate inconsistencies, and identify important areas for future research in women's health.

A prospective study of childhood social hardships and age at menarche

PURPOSE

To determine the role of type, timing, and cumulative childhood hardships on age at menarche in a prospective cohort study.

METHODS

A longitudinal analysis was undertaken of 4524 female participants of the National Child Development Study cohort (1958-2003). Six types of childhood hardships were identified with a factor analysis methodology. Paternal absence/low involvement in childhood was an a priori hardship. Retrospective reports of abuse in childhood also were explored in relation to age at menarche. Generalized logit regression analyses explored the impact of type, timing, and cumulative hardships on age at menarche (≤ 11, 12-13, ≥ 14 years).

RESULTS

Cumulative childhood hardships were associated with a graded increase in risk for later menarche with adjusted odds ratio [AOR] of 1.37 (95% confidence interval [95% CI], 1.10-1.70), 1.50 (95% CI, 1.18-1.91), and 1.58 (95% CI, 1.29-1.92) among those with two, three, and four or more adversities, respectively. More than two hardships in early life had the strongest association with late menarche (AOR, 2.32; 95% CI, 1.12-4.80). Sexual abuse was most strongly associated with early menarche (AOR, 2.60; 95% CI, 1.40-4.81).

CONCLUSIONS

Cumulative childhood hardships increased risk for later age at menarche. Child abuse was associated with both early and late menarche, although associations varied by type of abuse.

Cross-cultural equivalence of HSCL-25 and WHO (ten) Wellbeing index: findings from a population-based survey of immigrants and non-immigrants in Sweden

The aim of this study was to investigate whether the Hopkins Symptom Checklist (HSCL-25) and the WHO (ten) Wellbeing Index are cross-culturally equivalent by comparing Scandinavians with Middle Eastern immigrants in Sweden. The study population consisted of a stratified random sample of native-born Swedes and immigrants from Finland, Iraq and Iran. Both instruments loaded on a single factor in the respective populations. A few of the items did however not discriminate or predict equally well in the groups, nonetheless it was found to have marginally influenced the instruments' total scores in both groups. The analyses also revealed that the groups had similar intercept and slope when the exogenous factor traumatic episodes was used to predict the measurement scores, supporting scalar equivalency. In conclusion, the results support the use of these instruments in population-based surveys within multicultural Western societies.

Validity of age at menarche self-reported in adulthood

OBJECTIVE

To test the validity of age at menarche self-reported in adulthood and examine whether socioeconomic position, education, experience of gynaecological events and psychological symptoms influence the accuracy of recall.

DESIGN

Prospective birth cohort study.

SETTING

England, Scotland and Wales.

PARTICIPANTS

1050 women from the Medical Research Council National Survey of Health and Development, with two measures of age at menarche, one recorded in adolescence and the other self-reported at age 48 years.

RESULTS

By calculating the limits of agreement, kappa statistic and Pearson's correlation coefficients (r), we found that the validity of age at menarche self-reported in middle age compared with that recorded in adolescence was moderate (kappa = 0.35, r = 0.66, n = 1050). Validity was improved by categorising age at menarche into three groups: early, normal and late (kappa = 0.43). Agreement was influenced by educational level and having had a stillbirth or miscarriage.

CONCLUSIONS

The level of validity shown in this study throws some doubt on whether it is justifiable to use age at menarche self-reported in middle age. It is likely to introduce error and bias, and researchers should be aware of these limitations and use such measures with caution.
