Song S, Park S, Song BM, Lee JE, Cha C, Park HY. Risk of uterine leiomyomata with menstrual and reproductive factors in premenopausal women: Korea nurses' health study. BMC Womens Health 2023; 23:305. [PMID: 37296433 PMCID: PMC10257256 DOI: 10.1186/s12905-023-02447-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Accepted: 05/22/2023] [Indexed: 06/12/2023] Open
Abstract
BACKGROUND Uterine leiomyomata (UL) are benign smooth muscle tumors that may cause significant morbidity in women of reproductive age. This study aimed to investigate the relationship of menstrual and reproductive factors with the risk of UL in premenopausal women. METHODS This prospective study included 7,360 premenopausal women aged 22-48 years who were part of the Korea Nurses' Health Study. Information on the menstrual cycle and reproductive history was assessed between 2014 and 2016, and self-reported cases of UL were obtained through 2021. Cox proportional hazards models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS During 32,072 person-years of follow-up, 447 incident cases of UL were reported. After adjusting for other risk factors, women with late age at menarche had a lower incidence of UL (≥ 16 vs. 12-13 years: HR 0.68; 95% CI 0.47-0.99; p for trend = 0.026). The risk of UL was inversely associated with current menstrual cycle length (≥ 40 or too irregular to estimate vs. 26-31 days: HR 0.40; 95% CI 0.24-0.66) and cycle length at ages 18-22 years (HR 0.45; 95% CI 0.31-0.67; p for trend < 0.001, each). Parous women had lower risk of UL than nulliparous women (HR 0.40; 95% CI 0.30-0.53) and women who were aged 29-30 years at first birth had a lower risk of UL than those who were aged ≤ 28 years at first birth (HR 0.58; 95% CI 0.34-0.98). There was no significant association of the number of births or breastfeeding with the risk of UL among parous women. Neither a history of infertility nor oral contraceptive use was associated with the risk of UL. CONCLUSIONS Our results suggest that age at menarche, menstrual cycle length, parity, and age at first birth are inversely associated with the risk of UL in premenopausal Korean women. Future studies are warranted to confirm the long-term effects of menstrual and reproductive factors on women's health.

Association between ESR1 rs2234693 single nucleotide polymorphism and uterine fibroids in Taiwanese premenopausal and postmenopausal women. JOURNAL OF HEALTH, POPULATION, AND NUTRITION 2023; 42:16. [PMID: 36890612 PMCID: PMC9993586 DOI: 10.1186/s41043-023-00357-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Accepted: 02/28/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND Uterine fibroids (UFs) are uterine smooth muscle neoplasms that affect women, especially during the reproductive stage. Both genetic and lifestyle factors affect the onset of the disease. We examined the association between the estrogen receptor 1 (ESR1) rs2234693 variant (whose genotypes are TT, TC, and CC) and UFs in Taiwanese premenopausal and postmenopausal women. METHODS We linked individual-level data of 3588 participants from the Taiwan Biobank to the National Health Insurance Research Database at the Health and Welfare Data Science Center. The association of the ESR1 rs2234693 variant and other variables with UFs was determined by multiple logistic regression, and the results were presented as odds ratios and 95% confidence intervals (CIs). RESULTS The 3588 participants comprised 622 cases and 2966 controls. In all the participants, the ESR1 rs2234693 TC and CC genotypes compared to the reference genotype (TT) were associated with a lower risk of UFs. However, the results were significant only for the CC genotype (OR; 95% CI = 0.70; 0.52-0.93). Noteworthy, the association of TC and CC with UFs was dose-dependent (p-trend = 0.012). Based on menopausal status, both TC and CC were significantly and dose-dependently associated with a lower risk of UFs in premenopausal women (OR; 95% CI = 0.76; 0.59-0.98 for TC and 0.64; 0.43-0.95 for CC: p-trend = 0.010). CONCLUSION The TC and CC genotypes of the ESR1 rs2234693 variant may reduce susceptibility to UFs, especially in premenopausal women.

[PMID: 35477381 PMCID: PMC9044639 DOI: 10.1186/s12905-022-01721-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Accepted: 04/18/2022] [Indexed: 11/12/2022] Open
Abstract
Background Bet1 Golgi vesicular membrane trafficking protein-like (BET1L) rs2280543 single nucleotide polymorphism (SNP) and diet have been independently associated with uterine leiomyoma (UL). However, whether the SNP and diet could jointly influence the risk of UL is yet to be assessed. Therefore, we investigated the independent and interactive effects of vegetarian diet and BET1L rs2280543 on uterine fibroids in Taiwanese women.
Methods We linked participants’ electronic data in the Taiwan Biobank (TWB) database to their medical records in the National Health Insurance Research Database (NHIRD). The TWB had genotypic, lifestyle, and biochemical data between 2008 and 2015 and the NHIRD had data on disease diagnoses between 1998 and 2015. In this study, we included 1997 premenopausal women with complete data. Results Compared to participants with the BET1L rs2280543 CC genotype (wildtype), those with CT/CC genotype had an odds ratio (OR) of 0.69 and a 95% confidence interval (CI) of 0.51–0.93. Vegetarian diet and UL were not significantly associated: OR = 1.09 and 95% CI = 0.77–1.55. However, the test for interaction between rs2280543 and vegetarian diet was significant (p = 0.046). Compared to individuals with the CC genotype, the risk of UL was lower among vegetarians with the CT/TT genotype: OR (95% CI) = 0.15 (0.05–0.47). Conclusion The BET1L rs2280543 CT/TT genotype was associated with a lower risk of UL especially among vegetarians.

Abstract
Phthalates and environmental phenols might be associated with some benign diseases that have been found to be hormone-sensitive. Current knowledge on adverse effects of these chemicals among reproductive women is limited and often controversial. Therefore, the purpose of this study was to investigate the association between the urinary concentration of phthalates and environmental phenols and gynecological disorders from 512 women of reproductive age. The association between chemical concentration and disease in the control and case groups was statistically determined with the questionnaire survey data and measurements using the LC-MS/MS. The results have shown that DEHP metabolites, ethyl paraben and 3,4-DHB showed significant direct associations with leiomyoma and benign ovarian tumors (p < 0.05). We found statistically significant positive relationships between exposure to chemicals (some DEHP metabolites, DHB) and prevalence of gynecologic disorders (p < 0.05). Furthermore, the ORs for leiomyoma associated with these compounds in always user for personal care products (PCPs) was higher than those of sometimes user. High levels of urinary concentrations of these compounds such as DEHP metabolites and parabens and their metabolites showed significant associations with leiomyoma and benign ovarian tumors.

Abstract
We aimed to investigate whether life-course socioeconomic position mediates the association between skin color/race and occurrence of uterine leiomyomas. We analyzed 1,475 female civil servants with baseline data (1999-2001) of the Pró-Saúde Study in Rio de Janeiro State, Brazil. Life-course socioeconomic position was determined by parental education (early life socioeconomic position), participant education (socioeconomic position in early adulthood) and their combination (cumulative socioeconomic position). Gynecological/breast exams and health insurance status were considered markers of access to health care. Hazard ratios (HR) and 95% confidence intervals (95%CI) were estimated using Cox proportional hazards models. Compared with white women, black and parda ("brown") women had higher risk of reporting uterine leiomyomas, respectively HR: 1.6, 95%CI: 1.2-2.1; HR: 1.4, 95%CI: 0.8-2.5. Estimates were virtually identical in models including different variables related to life-course socioeconomic position. This study corroborated previous evidence of higher uterine leiomyomas risk in women with darker skin color, and further suggest that life-course socioeconomic position adversity does not influence this association.

Abstract
Introdução: Os miomas uterinos (MU) são considerados os tumores mais comuns do sistema reprodutor feminino; no entanto, existem poucos estudos epidemiológicos sobre essa condição no Brasil. Objetivo: Estimar as prevalências de história auto-relatada de MU segundo características demográficas, socioeconômicas e de acesso a serviços de saúde. Métodos: Foram analisados dados de 1.733 trabalhadoras de universidade no Rio de Janeiro, participantes da linha de base do Estudo Pró-Saúde (1999-2001), em relação a três desfechos: (1) diagnóstico médico de MU, (2) MU com sintomas prévios ao diagnóstico e (3) casos que realizaram histerectomia pelo tumor. As prevalências e seus intervalos de 95% de confiança (IC 95%) foram estimadas em relação a estratos de variáveis demográficas (idade, cor/raça), socioeconômicas (escolaridade, renda) e marcadoras de acesso a serviços de saúde (teste Papanicolaou , exame de mama, plano de saúde). Resultados: A prevalência de diagnóstico médico de MU foi de 23,3% (IC 95% - 21,3; 25,2); a de MU com sintomas prévios ao diagnóstico, de 13,3% (IC 95% - 11,7; 15,0) e a de histerectomia pelo tumor, de 8,4% (IC 95% - 7,5; 10,3). Entre participantes abaixo de 45 anos de idade, foram observadas prevalências mais elevadas nos estratos de piores condições socioeconômicas e de cor/raça preta. Entre aquelas com 45 anos ou mais, foram encontradas maiores prevalências entre mulheres com melhor acesso a serviços de saúde. Conclusão: Entre as mulheres brasileiras investigadas, os MU constituem problema relevante de saúde, com prevalências e gradientes sociodemográficos similares aos observados em populações de outros países.

Abstract
BACKGROUND Childhood adversities are associated with adult health. We hypothesize that exposure to physical and sexual abuse in childhood and adolescence will be associated with incidence of clinically symptomatic uterine leiomyomas (fibroids) through influences on health behaviors and reproductive hormone regulation. METHODS Participants included 68,505 women enrolled in the Nurses' Health Study II, an ongoing prospective cohort study of premenopausal women from 14 US states aged 25-42 years at enrollment (1989), who completed a retrospective questionnaire on childhood violence exposure (2001). A cumulative indicator of severity and chronicity of child/teen violence exposure was derived using factor analysis. We used a Cox proportional-hazards model to estimate the incidence rate ratios (IRRs) and 95% confidence intervals (CIs). RESULTS During the 728,865 woman-years of follow-up (1989-2005), 9823 incident diagnoses of ultrasound- or hysterectomy-confirmed uterine leiomyomas were reported; 65% reported any physical or sexual abuse. A dose-response association between cumulative abuse and fibroid risk was found. Compared with those who reported no abuse, multivariable IRRs for ultrasound or hysterectomy-confirmed uterine leiomyomas were 1.08 (95% CI = 1.03-1.13), 1.17 (1.10-1.24), 1.23 (1.14-1.33), 1.24 (1.10-1.39), and 1.36 (1.18-1.54), for cumulative exposures ranging from mildest to most severe. Increased emotional support in childhood also attenuated associations. CONCLUSIONS Severity and chronicity of child/teen sexual and physical abuse was associated with increasing risk of clinically detected fibroids among premenopausal women.

Abstract
Although uterine leiomyomata (also known as fibroids or myomas) affect the reproductive health and well-being of approximately 25% of premenopausal women, risk factors are poorly understood. Elevated diastolic blood pressure may increase fibroid risk through uterine smooth muscle injury, not unlike atherosclerosis. The authors prospectively examined the relation between diastolic blood pressure and incidence of clinically detected leiomyomata. The sample included 104,233 premenopausal nurses from 14 US states enrolled in the Nurses' Health Study II. Participants, aged 25-42 years, had intact uteri and no history of cancer or fibroids at enrollment in 1989. During the 827,348 woman-years of follow-up (1989-1999), 7,466 incident diagnoses of uterine leiomyomata, confirmed by ultrasound or hysterectomy, were reported. With a multivariable Cox proportional hazards model, the relative risk of self-reported ultrasound- or hysterectomy-confirmed uterine leiomyomata according to diastolic blood pressure in 1989 and time-varying antihypertensive use was estimated. With adjustment for age, race/ethnicity, body mass index, and reproductive history covariates, for every 10-mmHg increase in diastolic blood pressure, the risk of fibroids rose 8% (5-11%) and 10% (7-13%) among nonusers and users of antihypertensive medications, respectively. Elevated blood pressure has an independent, positive association with risk for clinically detected uterine leiomyomata among premenopausal women. Investigating this association may suggest possible pathways to prevent fibroids.

Abstract
BACKGROUND We examined the association of uterine leiomyoma with menstrual cycle characteristics in a population of non-care-seeking women. METHODS This cross-sectional study uses data from the Seveso Women's Health Study (SWHS), a population-based cohort in Italy. Participants included 341 premenopausal women, 30-60 years old, who had an intact uterus and were not pregnant, lactating, or using oral contraception or intra-uterine devices. We examined the presence of any ultrasound-detected uterine leiomyoma in relation to self-reported menstrual cycle length, flow length and heaviness of flow. The association of leiomyoma number, volume, tissue layer location and axial position with menstrual cycle characteristics was also examined. RESULTS Uterine leiomyomata were detected in 73 women (21.4%). After adjustment for covariates, the presence of a leiomyoma was not significantly related to menstrual cycle length, flow length or heaviness of flow [odds ratio (OR) for scanty flow =1.9, 95% confidence interval (CI) 0.8-4.3; OR for heavy flow =1.3, 95% CI 0.7-2.5; relative to moderate flow]. Number, volume, tissue layer location (subserosal or intramural) and axial position (anterior or posterior) of the leiomyoma were also not related to menstrual cycle characteristics. CONCLUSION In this Italian population of women not seeking gynaecological care, menstrual characteristics are not related to leiomyoma.

Abstract
Uterine leiomyomas, or fibroids, represent a major public health problem. It is believed that these tumors develop in the majority of American women and become symptomatic in one-third of these women. They are the most frequent indication for hysterectomy in the United States. Although the initiator or initiators of fibroids are unknown, several predisposing factors have been identified, including age (late reproductive years), African-American ethnicity, nulliparity, and obesity. Nonrandom cytogenetic abnormalities have been found in about 40% of tumors examined. Estrogen and progesterone are recognized as promoters of tumor growth, and the potential role of environmental estrogens has only recently been explored. Growth factors with mitogenic activity, such as transforming growth factor- (subscript)3(/subscript), basic fibroblast growth factor, epidermal growth factor, and insulin-like growth factor-I, are elevated in fibroids and may be the effectors of estrogen and progesterone promotion. These data offer clues to the etiology and pathogenesis of this common condition, which we have analyzed and summarized in this review.
