RESUMO

OBJECTIVE: To characterize the menstrual cycle (regularity and menstrual flow length), the prevalence of dysmenorrhea and self-monitoring of the cycle in students from Lisbon region, and explore the effect of chronological age, age at menarche and body mass index (BMI) on menstrual disorders. METHODS: This is a cross-sectional study with 848 girls aged 12-18 years. A questionnaire about the sociodemographic context and characteristics of the menstrual cycle, and weight and height measures were assessed. BMI was classified according to International Obesity Taskforce criteria. A descriptive analysis of the variables was made, and Odds Ratios (ORs) and 95% confidence intervals (95%CIs) were determined. RESULTS: Mean age at menarche was 12.4 years and mean BMI was 22.0kg/m2. Among adolescents, 59% have regular menstrual cycle, 83% have menstrual flow length of ≤6 days. 88% suffered from dysmenorrhea, among which 8,7% declare absenteeism from school and 49% took pain medication, and 65% self-monitor their menstrual cycle. Higher maternal education was associated with a higher self-monitoring of menstrual cycle among the sample (OR 1.60; 95%CI 1.15-2.17). Girls with menarche <12 years-of-age are more likely to have menstrual flow length of >6 days (OR 1.73; 95%CI 1.19-2.51) and dysmenorrhea (OR 1.87; 95%CI 1.11-3.16) than those with menarche ≥12 years-of-age. No significant association between BMI and menstrual cycle variables was observed. CONCLUSIONS: The results suggest that menstrual disorders are frequent and may be associated with early menarche, but not with BMI. It is important to encourage self-monitoring of the menstrual cycle to detect menstrual disorders timely and promote health and well-being.

RESUMO

Some reproductive factors are found to be associated with metabolic outcomes in women; however, little is known about reproductive lifespan characteristics and the mutual effect of age at menarche and age at menopause on cardiovascular risk. This systematic review evaluated reproductive lifespan characteristics and describes the mutual effect of age at menarche and age at menopause on the risk of type 2 diabetes (T2DM) and hypertension at midlife. PubMed, EMBASE, and Web of Science were screened for studies published up to September 1, 2020. The individual effect estimates were reviewed and synthesized without meta-analysis due to methodological and clinical or conceptual diversity in reported studies. Of the 3033 identified studies, 20 were included in the final synthesis: 6 reported reproductive life span; 12 reported age at menarche, and 7 reported age at menopause. Synthesis of two cohorts, with a median follow-up of 9-11 years, showed that a shorter reproductive lifespan was positively associated with T2DM, yielding 6-15% higher risk of T2DM for a one-year decrease in reproductive lifespan. A few studies also demonstrated that women who experienced early menarche (four of six studies) and early menopause (two of five studies) were positively associated with risk of T2DM. The association between reproductive lifespan and hypertension was unclear due to the limited availability of studies. Our findings suggest that a shorter reproductive lifespan is associated with T2DM risk in postmenopausal women, especially those with early menarche and early menopause. Large cohort studies are needed to assess the association between reproductive lifespan and incident hypertension in midlife.

RESUMO

OBJECTIVE: The aim: To determine current age at the initiation of puberty for Ukrainian school-aged girls and infections impact to puberty. PATIENTS AND METHODS: Materias and methods: We performed a multicentre cohort study. The analyses are based on data that were collected and evaluated biannually on Ukrainian school girls aged 6-17 years from 5 regions of Ukraine. Pubertal development was classified according to the Marshall and Tanner criteria. RESULTS: Results: Overall, 2,784 girls have been included in the study. Mean age of onset of puberty in Ukrainian girls was 10.1±1.0 yrs. Age of onset of pubic hair was 11.0±1.0 yrs and that of axillary hair was 11.6±1.0 yrs. Mean age in girls of menarche was 12.2±0.9 yrs. There were no significant correlations between age at onset of puberty and body mass index, final height, total peak height velocity, duration of puberty, and peak height velocity. A total of 2,420 infectious diseases were diagnosted. Of these, 64.8% were viral and 35.2% bacterial infections, respectively. Ukrainian girls with infectious diseases (especially viral infections) had older age at pubertal onset and positive association of infections in childhood with late age of menarche. CONCLUSION: Conclusions: Infectious morbidity (especially viral infections) in girls may be associated with later puberty. The lowering of the number of infections in childhood could be an additional factor that contributes to earlier puberty. To reduce infectious diseases, more attention should be paid to the vaccination of children.

RESUMO

Objective: To explore the relationship between age at menarche and general obesity (based on BMI) and central obesity (based on WC or WHtR) in middle-aged and elderly women in China. Methods: A total of 6 363 women from the China Health and Retirement Longitudinal Study were included. Restricted cubic splines based on binary logistic regressions were used to analyze the relationship between age at menarche and the risk of obesity. Age at menarche was divided into four groups: ≤13, 14- (control group), 16- , and ≥18 years old. Binary logistic regressions were applied to analyze the relationship between the continuous or grouped variable of age at menarche and the risk of obesity. Results: After adjusting potential confounders, the age at menarche showed a negative linear relationship with the risk of general obesity and central obesity. The risk for obesity based on BMI, WC and WHtR significantly decreased by 6% (OR=0.94, 95%CI: 0.90-0.99), 4% (OR=0.96, 95%CI: 0.92-1.00), and 6% (OR=0.94, 95%CI: 0.90-0.99) for each 1 year increase in age at menarche. Compared with participants who had menarche at age 14- years old, the risk for obesity based on BMI (OR=0.71, 95%CI: 0.55-0.91), WC (OR=0.75, 95%CI: 0.62-0.92) and WHtR (OR=0.76, 95%CI: 0.61-0.96) significantly decreased by 29%, 25%, and 24% in participants who had menarche at age ≥18 years old. Conclusions: There was a negative linear relationship between age at menarche and the risk for general obesity and central obesity in middle-aged and elderly women in China. Older age at menarche might be negatively associated with risk for obesity in middle-aged and elderly women.

RESUMO

BACKGROUND: Age at menarche (AAM) has shown different trends in women from different ethnic and economic regions in recent decades. Data on AAM among multiethnic women living in developing areas are scarce. METHODS: Data on AAM from 1,275,000 women among 26 ethnicities in Yunnan Province, China, who were born from 1965 to 2001 were obtained from the National Free Preconception Health Examination Project from 2010 to 2018. The patterns of AAM trends were analysed according to ethnic group, area of residence, and socioeconomic status. RESULTS: The mean AAM was 13.7 ± 1.21 years (95% CI 13.697-13.701), with a decrease from 14.12 (±1.41) among women born before 1970 to 13.3 (±1.04) among those born after 2000. The decline was 0.36 years per 10-year birth cohort, and the plateau has not yet been reached in Yunnan. A secular trend of earlier AAM was observed in all 26 ethnic groups. The fastest rate of decline was observed for the Bai ethnicity (0.36 years per decade). Consistent declining trends in AAM appeared among extreme-, middling-, and nonpoverty economic patterns from 1965 to 2001, with reductions of 1.19, 1.44, and 1.5 years, respectively (P < 0.001). The peak reduction among middling poverty and extreme poverty occurred in the early 2000s (0.4 and 0.32 years). Multivariate analysis showed a significant difference in the declining trends in AAM along rural/urban lines (P < 0.001). CONCLUSION: There was a secular trend towards a younger AAM during the twentieth century and early twenty-first century birth cohorts in the Yunnan population. Considering the difference in AAM trends due to ethnic and socioeconomic status in Yunnan, the health authority should utilize flexible adjusted health care strategies in different regions.

RESUMO

Evidence suggests that girls spend much time on social networking sites (SNS), often more than boys do. It has been proposed that this may have to do with sex-based differences in the need and approaches for socialization. We posit that adolescent girls are also unique in that they are developing physiologically and start menstruating. Based on prior research, we hypothesize that the onset of menstruation can drive physiological changes (increased body mass index (BMI)), which together with common behavioral-psychological (social and emotional) responses to menstruation can contribute to an increase in SNS use. We therefore aim to test whether BMI partially mediates the relationship between menstruation and SNS use in adolescent girls. Results based on a large nationally representative sample in the United Kingdom suggest that the age of menarche was negatively associated with daily hours of SNS use, and that BMI elevation partially mediated this association. These results extend the negative effects of the early onset of menstruation and imply that BMI control strategies may help to reduce the use of SNS in girls who experience menarche at an earlier age.

RESUMO

Based on the data from China Health and Nutrition Survey (CHNS), 840 girls aged 6-15 years who had information about menarche and participated in dietary survey at least once within 1-5 years before onset of menarche between 1989 and 2015 were included in the study. The median age at baseline of the 840 participants was 10 (9, 11) years. The median age at menarche of the participants was 13 (12, 14) years. After adjusting for the age of birth, place of residence, body mass index Z-score, physical activity level and annual household income per capita, the average age of menarche was advanced by 0.036 (95%CI: -0.068, -0.004) years for every 10 g increase in daily fat intake before menarche. The average age at menarche was 0.008 (95%CI: -0.014, -0.001) years earlier for every 1% increase in the daily energy supply ratio of fat before menarche.

RESUMO

Objective: Patients with cystic fibrosis (CF) have a high incidence of pubertal and growth delay. In girls with CF, pubertal delay has an important psychological impact. Still, only a few studies have explored the occurrence of pubertal delay in girls with CF. The aims of this study were to compare the pubertal development of girls with CF compared with healthy controls regarding Tanner staging and pelvic ultrasound and, in girls with CF, correlate the findings with those of spirometry, body mass index, Shwachman-Kulczycki score (SKS), and genotyping. Methods: This was a cross-sectional, case-control study including 35 girls with CF aged 6-17 years and following up at the Pediatric Pulmonology Outpatient Clinic of a tertiary hospital. These patients were compared with 59 healthy controls who had undergone pelvic ultrasound as part of another study conducted by the same group. Girls with CF were consecutively enrolled in the study during their annual routine check-up visit. Data collected in the CF group included spirometry and anthropometric results, SKS values, bone age, occurrence of current cystic fibrosis-related diabetes (CFRD) and Pseudomonas aeruginosa colonization, history of meconium ileus, genotype, ultrasound parameters, and Tanner stage. Results: Pelvic ultrasound findings and Tanner stage reflected less pubertal development in girls with CF compared with healthy controls. Pubertal stage in patients with CF who presented CFRD (3.17 ± 1.16), had chronic colonization by Pseudomonas aeruginosa (3.10 ± 1.10), or were homozygous for the F508del mutation (1.91 ± 1.30) was more delayed than in controls (3.41 ± 1.41). Tanner stage correlated with age at menarche, bone age, and anthropometric and ultrasound data. Conclusion: Girls with CF presented a delay in pubertal development evaluated by Tanner stage and ultrasound parameters, which was more evident in the presence of comorbidities.

RESUMO

Objective: The objective is to investigate the timing of pubertal onset as determined by the development of secondary sexual characteristics in relation to body weight and dietary patterns among Saudi females. Methods: Children/adolescents visiting general and endocrinology pediatric clinics in King AbdulAziz University Hospital were invited to participate in this study. Female subjects between the ages of 5 and 20 years were included in this study, and those with syndromic disease, chronic comorbidities, endocrinopathies, organic causes of precocious puberty, positive family history of early pubertal onset, and under chronic medication were excluded from the study. Data were collected through clinical interviews with the consent of the legal guardians, and physical examinations were conducted. Results: A.total of 164 females were investigated. The mean age of thelarche, adrenarche, and menarche was 10, 11.3, and 12.2 years, respectively. We found a significant correlation between higher weight standard deviation and an earlier age of both thelarche and adrenarche. In addition, daily consumption of fast foods was significantly associated with an earlier menarchal age. Consumption of nonorganic poultry was linked to early thelarche. Conclusion: Efforts should be directed to increase public and community awareness that fast food consumption, inorganic poultry, and higher body weight are important modifiable factors that lead to an earlier onset of female puberty across different parameters: breast development, adrenarche, and menstruation.

RESUMO

ABSTRACT: Early menarche can be the socio-psychological problems. We studied the association between early menarche and suicidal risk behaviors among South Korean girl adolescents using national-wide data.Web-based self-report data from 2006 to 2015 the Korea Youth Risk Behavior Web-based Survey data were used in this study. Menarche status was divided into an "early menarche" group (at <12 years of age) versus "not early" menarche group (at ≥12 years of age).Participants with adolescent girls with early menarche group showed a higher prevalence of substance use, higher levels of stress, poorer self-rated health status, unhappier perceiveness, more frequent depressed mood, inter-sexual kissing or petting, inter-sexual intercourse, homosexual kissing or petting, being the victim or the assailant of sexual assaults, sexual transmitted diseases experience, pregnancy, and abortion experience than the not early menarche group. Adolescent girls with early menarche who had suicidal ideation (25.4% vs 22.2%, P < .001), suicidal plans (4.1% vs 2.6%, P < .001), and suicidal attempts (6.8% vs 5.2%, P < .001) were higher than that in the adolescent girls with not early menarche. A multivariate analysis after adjusting revealed that the odds ratios for suicidal ideation, plans, and attempts were 1.07 (95% confidence interval [CI]: 1.05-1.10), 1.35 (95% CI: 1.28-1.41), and 1.13 (95% CI: 1.09-1.18), respectively.Adolescent girl with early menarche was associated with suicidal behaviors.

RESUMO

BACKGROUND: Early age at menarche, late age at menopause, and late age at first full-term pregnancy are linked to a modest increase in the risk of developing breast cancer (breast ca). This study aims to investigate the reproductive determinants of breast cancer among women in the West Bank of Palestine. A structured questionnaire was used to collect data in a case-control study (237 registered cases and 237 controls). A multivariate analysis model was used to adjust for the association between women's reproductive factors and breast ca risk. This study was approved by Al Quds University Ethical Research Committee and the Ministry of Health research unit. RESULTS: In the multivariate analysis, menarche after 13 years of age, use of oral contraceptives for more than two months, and hormonal contraceptives use significantly doubled the risk for breast ca (Adjusted Odds Ratio (AOR) = 2.03, 95 % CI: 1.21-4.37, p < 0.011 and AOR = 2.2, 95 % CI: 1.24-4.01, p = 0.008, respectively). Women who used hormone replacement therapy (HRT) were significantly associated with higher odds (5 folds) of having breast ca versus those who did not use them (AOR 5.02, 95 % CI: 1.93-13.06, p = 0.001). Similarly, nulliparous women showed 6 times the odds of breast ca compared with women with one or more children (p = 0.005). Also, parental consanguinity marriage (AOR 2.59, 95 % CI: 1.53-4.36, p = 0.001) and positive family history (AOR 3.88, 95 % CI: 2.19-6.87, p = 0.001) of the condition can be strong determinants for breast ca in this study. CONCLUSION: This study provides clear evidence that the use of reproductive hormones, whether as a birth control tool or for therapeutic purposes, must be rationalized worldwide and in Palestine in particular.

RESUMO

BACKGROUND: Due to the diversity in profiles associated with the female reproductive cycle and their potential physiological and psychological effects, monitoring the reproductive status of exercising females is important from a practical and research perspective. Moreover, as physical activity can influence menstrual function, the effects of physical activity energy expenditure on reproductive function should also be considered. AIM: The aim of this study was to develop and establish initial face and content validity of the Health and Reproductive Survey (HeRS) for physically active females, which is a retrospective assessment of menstrual function from menarche (first menstruation) to menopause (cessation of menstruation). METHODS: Face validity was evaluated qualitatively, and the initial content validity was established through a principal component analysis. The face validity process was completed by 26 females aged 19-67 years and the content validity was established through a survey sent to a convenience sample of 392 females, of which 230 females (57.9% and aged 18-49 years) completed the survey. RESULTS: The revisions made following the face validation improved the understanding, flow, and coherence of the survey. The principal component analysis indicated that, at a minimum, the survey measures these constructs: menstrual cessation and associated moderators, athletic participation and performance levels (as associated with menstruation change and the menstrual cycle), age and menstrual cessation, hormonal contraception ("birth control"), and menarche and associated moderators. CONCLUSION: The Health and Reproductive Survey (HeRS) is a partially validated tool that can be used by researchers to characterize the menstrual status of physically active females relative to their physical activity status.

RESUMO

There are many unique aspects of asthma in women. Compared with men, women go through several hormonal stages over the life span-childhood, menarche, reproductive years, pregnancy, menopause, and postmenopause-and each affects asthma. Onset of asthma in women differs from men. Asthma in women is more often associated with obesity and women are over-represented among patients with severe asthma, including those being prescribed biologic therapies. Asthma affects fertility and pregnancy, and female hormone replacement therapy has been found to affect asthma onset as well as asthma severity. We explore the unique aspects of asthma in women.

RESUMO

Background: The aim of the study was to assess the influence of both physical activity, such as running and dancing, and the personal characteristics of the studied women on the occurrence and progression of premenstrual disorder (PMD). Methods: We surveyed 414 women aged 22-48 who were experiencing the menstrual cycle but not using hormonal contraception. There were two physically active groups, runners (N = 215) and Argentine tango dancers (N = 94), and there was one group not undertaking any physical activity-the control group (N = 104). The research was conducted using the researchers' own questionnaire. Results: The number of days of PMD symptoms in the tango vs. runner vs. control groups are as follows: pre-bleeding (mean: 4.14 vs. 4.86 vs. 4.85; p = 0.024), after the onset of bleeding (mean: 1.76 vs. 2.39 vs. 2.16; p = 0.001), and in total (mean: 5.94 vs. 7.25 vs. 7.01; p < 0.001). The regression analysis results without grouping results are as follows: the number of days of symptoms before bleeding and menarche (B: -0.16; 95% CIs: from -0.29 to -0.04; p = 0.011), the total duration of symptoms and menarche (B: -0.17; 95% CIs: from -0.32 to -0.01; p = 0.036), lower abdominal pain and age (B: -0.05; 95% CIs: 0.92-0.98; p = 0.002), diarrhoea (B: -0.08; 95% CIs: 0.88-0.97; p < 0.001), tearfulness, depressive states and age (B: -0.06; 95% CIs: 0.91-0.97; p < 0.001), skin problems and age (B: -0.05; 95% CIs: 0.92-0.98; p = 0.004), joint pain and age (B: -0.09; 95% CIs: 0.86-0.96; p = 0.001), pain in the lumbar spine (B: -0.06, 95% CIs: 0.91-0.98; p = 0.001), water retention and BMI (B: 0.09; 95% CIs: 0.92-0.98; p = 0.007), and water retention and menarche (B: -0.19; 95% CIs: 0.73-0.94; p = 0.003). Information: generally there is one regression model, we have several here, we have a bit the description. Conclusions: Physical activity such as dancing (tango) shortens the duration of PMD symptoms but does not completely eliminate them. Running does not have as beneficial an effect on symptom relief as dancing. Current age, age when menstruation began (menarche), and BMI were revealed to be important factors influencing the symptoms of premenstrual disorders.

RESUMO

In this work, we used a cross-sectional study to evaluate influence of menarche age, menstrual cycle, menstrual period, menopausal age, and menopause years for osteoporosis in women from China. We found that different menarche age, menstrual cycle, menopausal years, and menopausal age are related with the prevalence of osteoporosis. However, menarche age exceeds 17 years and menopausal age smaller than 48 years are risk factors for osteoporosis in women. STUDY DESIGN: A cross-sectional, population-based study. PURPOSE: The purpose of this study was to explore relationship between prevalence of osteoporosis and menarche age, menstrual cycle, menstrual period, menopausal age, and menopause years for women. METHODS: From March to October 2016, the cluster sampling method was used to conduct an osteoporosis-related questionnaire survey on women aged 40-80 in two communities in Lanzhou City, Gansu, China, and bone mineral density(BMD)was carried out using the DTX-200 dual-energy X-ray absorptiometer produced by the US OSTEOMETER company. The relationship between prevalence of osteoporosis and menarche age, menstrual cycle, menstrual period, menopausal age, and menopause years were analyzed using logistic regression analysis. RESULTS: There were 2224 female participates enrolled in this study and average age was 61.60 ± 8.05 years and total rate of prevalence was 32.73%; among them, different menarche age, menstrual cycle, menopausal years, and menopausal age have statistical differences with the prevalence of osteoporosis, but there is no statistical difference between different menstruation and the prevalence of osteoporosis. Single logistic regression analysis found that older menarche age, earlier menopausal age, and longer menopausal years were related factors for the prevalence of osteoporosis, while menarche age exceed 17 years and menopausal age smaller than 48 years are risk factors for osteoporosis for women in multivariate regression analysis. CONCLUSIONS: In China, ages at menarche and menopause are associated with prevalence of osteoporosis. Later, menarche and earlier menopause are associated with higher osteoporosis risk. Menarche and menopause history may help identify women with increased risk of developing osteoporosis.

RESUMO

OBJECTIVE: To investigate the interval from menarche to the onset of premenstrual symptoms and its relationship with menarche age. DESIGN: Cross-sectional school-based survey. SETTING: Urban areas of Sendai, the largest city in northeastern Japan. PARTICIPANTS: 1422 female Japanese 10th-12th grade senior high school students participated in the survey. MAIN OUTCOME MEASURES: The time of awareness of premenstrual symptoms, and the interval from menarche to the onset of premenstrual symptoms. RESULTS: 1290 students had menstruation and completed the whole survey. The median age at menarche was 12 years (IQR: 11-13 years). The prevalence of self-reported premenstrual symptoms was 49%. The median age at which students became aware of premenstrual symptoms was 15 years (IQR: 14-16 years). The median time from the onset of menarche to awareness of premenstrual symptoms was 2 years. This time was negatively correlated with menarche age (ρ=-0.47, p<0.001). A Cox proportional hazards regression analysis revealed that early menarche was significantly associated with a lower cumulative risk of developing premenstrual symptoms (OR: 0.73 (95% CI 0.58 to 0.91)). CONCLUSIONS: High school students in Japan began experiencing premenstrual symptoms at around 15 years old, and within 2 years of menarche. This study suggested that social factors other than hormonal factors, such as early menarche, might be associated with the onset of premenstrual symptoms.

RESUMO

This study explored the association between age at menarche and the risk of hypertension in Chinese women. A total of 234 867 women aged ≥18 years from the China Hypertension Survey were included in this study. Participants were required to complete a standard questionnaire. Blood pressure and physical examination of the participants were performed by trained medical staff. Spearman correlation analysis was used to explore the correlation between age at menarche and other individual characteristics. Logistic regression was used to estimate the odds ratios for hypertension by age in years at menarche. The average age at menarche in Chinese women was 14.8 years. Women who were older at menarche were more likely to have a higher body mass index, larger waist circumference, smoke, and have a primary education (p < .05). After adjustments, odds ratios (95% confidence interval) for hypertension across age at menarche groups were 0.912 (0.877-0.948), 0.927 (0.893-0.963), 1.00 (reference), 1.061 (1.020-1.102), and 1.129 (1.090-1.169) for those aged ≤13, 14, 15 (reference), 16, and ≥17 years at menarche, respectively. Each 1-year delay in menarche was associated with a 6.2% increase in the prevalence of hypertension (odds ratio, 1.062; 95% confidence interval, 1.053-1.071). The positive association between age at menarche and hypertension was evident among age at recruitment groups, BMI categories, and education levels. This association was stronger in urban women and postmenopausal women. Our findings suggest that late menarche is related to a higher risk of hypertension among Chinese adult women, and this association appeared similar among different subgroups.

RESUMO

The purpose of this investigation was to study whether prolonged competitive rhythmic gymnastics training influenced bone mineral accrual in premenarcheal girls. Eighty-nine girls (45 rhythmic gymnasts [RG] and 44 untrained controls [UC]) between 7 and 9 years of age were recruited and measured annually for four years (not all participants were measured at every occasion). Dual energy x-ray absorptiometry was used to assess the development of whole body (WB), femoral neck (FN) and lumbar spine (LS) bone mineral content (BMC). In addition, body composition, blood adipokine and jumping performance characteristics were obtained. For longitudinal analyses, hierarchical mixed-effects models were constructed to predict differences in the development of WB, FN and LS BMC between RG and UC groups, while accounting for differences in body composition, blood adipokine and jumping performance values. It appeared that from 8 years of age, RG had lower (p < 0.05) fat mass and leptin values, and higher (p < 0.05) jumping performance measures in comparison with UC girls. Hierarchical mixed-effects models demonstrated that RG had 71.9 ± 12.0, 0.23 ± 0.11 and 1.39 ± 0.42 g more (p < 0.05) WB, FN and LS BMC, respectively, in comparison with UC girls. In addition, WB, FN and LS BMC increased more (p < 0.05) between 7 to 12 years of age in RG girls in comparison with UC. In conclusion, these findings suggest that the prolonged exposure to competitive rhythmic gymnastics trainings in premenarcheal girls is associated with greater bone mineral accrual despite lower body fat mass and leptin values.

RESUMO

INTRODUCTION: Back pain (BP) experienced by females during adolescent years appears to predispose them to an increased likelihood of its presence in adulthood. Understanding this phenomenon by identifying risk factors of those at risk potentially fosters preventative strategies and effective treatments. OBJECTIVES: To investigate for associations between post-menarche BP and low back pain (LBP) and age at menarche (AAM) in Australian adolescents using the Western Australian pregnancy cohort (The Raine Study). METHODS: This study used data from a longitudinal cohort study. BP data were collected retrospectively using a questionnaire. Menarche data was split into three established age classifications early (<12-years), normal (≥12 to >14-years) and late (≥14-years). Logistic regression models examined the effect of AAM on BP. RESULTS: 666 female participants provided valid menarche data with 183 (27.5%) early AAM, 429 (64.4%) normal AAM and 54 (8.1%) with late AAM. The mean AAM was 12.59 years. BP was disclosed by 27.5% in the 14-year follow-up and 31.5% in the 17-year follow-up. Participants who had early AAM had 79% higher odds of experiencing BP compared to participants who had normal AAM, after adjusting for confounders at the 14-year follow-up (adjOR 1.79, 95% CI 1.18-2.64). CONCLUSION: There is evidence of an association, in this cohort, of early AAM with post-menarche BP. This result identifies an area for future exploration, including understanding this mechanism which may lead to the development of effective intervention measures. SIGNIFICANCE: Age at menarche is related to a range of health issues. This study sought to investigate if it was a risk factor for spinal pain. We used an existing Australian data base to explore this possibility and found an association with early age onset and post-menarche back pain. This result identifies an area for future exploration, including understanding this mechanism which may lead to the development of effective intervention measures.
