Impact of COVID-19 infections and vaccination on menstrual cycle symptoms in the south of Jordan: a cross-sectional study. J Egypt Public Health Assoc 2024; 99:8. [PMID: 38594493 PMCID: PMC11004099 DOI: 10.1186/s42506-024-00153-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 03/11/2024] [Indexed: 04/11/2024]
Abstract
BACKGROUND Several recent studies have highlighted the need for more evaluation of the impact of COVID-19 infections and vaccines on the reproductive system and menstruation. This study aimed to assess the impact of COVID-19 infection and vaccines on menstrual symptoms. METHODS A cross-sectional survey utilizing face-to-face interviews from January 1 to 31 March 2022 was conducted in the city of Al-Karak in southern Jordan. The questionnaire included sociodemographic characteristics, medical and reproductive history, the contraceptive method used if any, menstrual cycle (MC) status, previous medical and drug history, and the impact of infection and vaccination on the MC. RESULTS The study questionnaire was completed by 400 participants with a mean age of 32.1±12.6 years. Regarding the history of COVID-19 infections, 33.8% of the participants reported a history of confirmed COVID-19 infections, 77.8% of them did not report any menstrual changes following the infection, while the remaining 22.2% reported changes in menstruation. The most commonly reported post-COVID-19 manifestations were irregular (27.6%) and light menstrual cycle (MC) (24.15) or dysmenorrhea (24.1%). Heavy menstruation was reported by 17.2% of participants post-COVID-19 infection. Two-thirds of the study participants (66.6%) reported no changes in the MC following the administration of the COVID-19 vaccine. The most reported symptoms for those who experienced changes in the MC following the vaccination were irregular cycle (13.1%), heavy menstruation (7%), and light menstruation (7%). Other reported symptoms were dysmenorrhea (4.6%), intermenstrual bleeding (1.2%), and amenorrhea (0.5%). CONCLUSION This study revealed minor changes in the MC following COVID-19 infections and administration of the COVID-19 vaccine. These findings are consistent with published reports. It is recommended that future clinical trials for new vaccines for women of childbearing age include outcomes related to sex hormones and MC. Women should be encouraged to take the vaccines and report symptoms to healthcare professionals for further assessment.

The effect of perceived stress on menstrual complaints in university students. Women Health 2024; 64:341-349. [PMID: 38556786 DOI: 10.1080/03630242.2024.2337705] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Accepted: 03/27/2024] [Indexed: 04/02/2024]
Abstract
Studies have examined the effect of stress on dysmenorrhea and premenstrual syndrome. For this reason in this study, it was aimed to determine the impact of stress on menstrual symptoms (adverse effects, abdominal pain, and coping methods). This descriptive and correlational study was conducted with 351 university students in Turkey by sharing the link to the questionnaire on online social media platforms. It was determined that those whose income was equal to their expenses had lower menstrual symptoms, having a chronic disease and smoking increased menstrual symptoms (F = 3.19/p = .04; t = 2.33/p = .02; t = 3.96/p = .00). The study identified that there was a positive low-level correlation (r: 0.25, p < .01) between the Perceived Stress Scale-14 and the Menstruation Symptom Questionnaire, and the 6.5 percent change in menstrual symptoms was explained by perceived stress. In the study, it is thought that stress affects the experience of menstrual symptoms. Therefore, it is believed that by providing training on stress and effective coping methods by midwives and nurses, menstrual symptoms can be reduced, contributing to women's health. For future studies, it is recommended to examine the effects of stress coping methods training on stress and menstrual complaints.

The impact of COVID-19 on menstrual cycle's alterations, in relation to depression and sleep disturbances: a prospective observational study in a population of medical students. BMC Womens Health 2024; 24:130. [PMID: 38373995 PMCID: PMC10877769 DOI: 10.1186/s12905-024-02971-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Accepted: 02/12/2024] [Indexed: 02/21/2024] Open
Abstract
BACKGROUND The sars-Cov-2 pandemic has determined psychological stress, particularly in the young population of medical students. We studied the impact of the pandemic on menstrual cycle alteration in relation to psychological stress, presence of depression, sleep disturbances and post-traumatic stress, on a population of medical students. METHODS 293 female students at the Faculty of Medicine and Psychology of the Sapienza University of Rome (23.08 years old ± 3.8) were enrolled. In March 2021, one year after quarantine, a personal data sheet on menstrual cycle, examining the quality of the menstrual cycle during the pandemic, compared to the previous period. Concomitantly, the Beck Depression Inventory and the Impact of Event Scale have been administered. A Pearson chi-square test was assessed to evaluate the difference between the characteristics of the menstrual cycle and the scores obtained with the questionnaires. RESULTS A statistically significant association between menstrual alterations and stress during pandemic had been found. The onset of depressive symptoms and sleep disturbances was observed in 57.1% and in 58.1% of young women with cycle's alterations, respectively. Amenorrhea was three times more common in female students with depressive symptoms, premenstrual syndrome had a significant correlation with both depression and sleep disturbances. The pandemic has been related to menstrual alterations, with depressive symptoms and sleep disorders. Amenorrhea is connected to depression, as observed on the functional hypothalamic amenorrhea. CONCLUSIONS The pandemic affected the menstrual cycle as well as the depressive symptoms and sleep. Practical implications of the study lead to the development of strategies for psychological intervention during the pandemic experience, in order to help medical trainees, with specific attention to women's needs. Future studies should analyze the impact of other types of social stress events, on sleep, depression and the menstrual cycle beside the pandemic.

Abstract
Purpose of review a)The modifiable and non-modifiable determinants and the currently available methods of assessment of menstrual blood flow will be discussed, with the goal of helping healthcare providers, researchers, and those interested in public health. Recent findings b)Several factors can impact menstruation. The determinants include modifiable factors such as smoking, nutrition, exercise, stress, weight fluctuation, and benign gynecologic diseases, and non-modifiable factors such as age, race, and the individual's genes. The intertwined dynamic among these determinants needs more critical attention. Currently, the methods for the assessment of menstruation all have advantages and disadvantages, often with a tradeoff between practicality and accuracy. Summary c)Considered by many as the fifth vital, menstruation provides a window to an individual's general health. The discussion of its determinants and assessment can be more appropriate for individual contexts, especially from a public health perspective as it can improve the reproductive health of the population.

The Effect of COVID-19 Vaccination on the menstrual cycle in female in Riyadh, Saudi Arabia. Saudi Pharm J 2023; 31:746-751. [PMID: 37128295 PMCID: PMC10063452 DOI: 10.1016/j.jsps.2023.03.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Accepted: 03/24/2023] [Indexed: 04/03/2023] Open
Abstract
Background Recently, few studies have mentioned minor changes in women's menstrual cycle after the COVID-19 vaccination. There were many reported cases of female menstrual cycle problems in primary healthcare clinics in Riyadh, Saudi Arabia. The study aimed to explore the prevalence of menstrual irregularities after the COVID-19 vaccine among females of childbearing age in Riyadh, Saudi Arabia. Materials and Methods This observational cross-sectional study was conducted from dec 2021 to June 2022 in Saudi Arabia. The study was carried out by using a convenience sampling technique. Results Our analysis includes 1066 participants. Abnormal menstruation was significantly associated with hypertension (p-value = 0.024), polycystic ovary syndrome (p-value = 0.001), and at least one gynaecological condition (p-value < 0.001). However, the multivariate regression analysis showed that menstrual abnormality before receiving the COVID-19 vaccine (OR = 0.09, 95% CI, 0.06 to 0.14, p-value <0.001) was more likely to be associated with abnormal menstruation after receiving the vaccine. Conclusions Our study findings showed a significant association between covid-19 vaccination and menstruation irregularity before administering the covid-19 vaccine, irrespective of vaccine type or the number of doses administered. Future and ongoing clinical trials should investigate menstrual abnormalities, other abnormal vaginal bleeding and hormonal changes post-vaccination, especially the COVID-19 vaccine.

COVID-19 vaccination and changes in the menstrual cycle among vaccinated persons. Fertil Steril 2023; 119:392-400. [PMID: 36539055 PMCID: PMC9758067 DOI: 10.1016/j.fertnstert.2022.12.023] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 12/13/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022]
Abstract
OBJECTIVE To describe the characteristics of people who experience changes to their menstrual cycle after COVID-19 vaccination. DESIGN Longitudinal study. PATIENT(S) We recruited a volunteer sample with and without a history of SARS-CoV-2 infection who enrolled in the Arizona COVID-19 Cohort (CoVHORT) study and participated in a reproductive sub-cohort who were pre-menopausal, not pregnant, and had received a COVID-19 vaccine in 2021 (n = 545). EXPOSURE(S) Demographic and reproductive characteristics were collected via self-reports. MAIN OUTCOME MEASURE(S) Information on self-reported changes in the menstrual cycle after COVID-19 vaccination was collected from May 2021 to December 2021. We looked at demographic and reproductive characteristics as predictors of menstrual cycle change. RESULT(S) The majority of our vaccinated sample received the Pfizer-BioNTech vaccine (58%), and were 26-35 years old (51%), non-Hispanic (84%), and White (88%). Approximately 25% of vaccinated participants reported a change in their menstrual cycle after vaccination; the majority reported changes after their second dose (56%) as compared with their first (18%) and third (14%) doses. The most commonly reported changes were irregular menstruation (43%), increased premenstrual symptoms (34%), increased menstrual pain or cramps (30%), and abnormally heavy or prolonged bleeding (31%). High self-reported perceived stress levels compared with low perceived stress (OR, 2.22; 95% CI 1.12-4.37) and greater body mass index (OR, 1.04; 95% CI 1.00-1.07) were associated with greater odds of experiencing the menstrual cycle changes after the vaccination. Participants having a history of SARS-CoV-2 infection were less likely to report changes in their menstrual cycle after vaccination compared with the participants with no history of SARS-CoV-2 infection (OR, 0.58; 95% CI 0.32-1.04). CONCLUSION(S) Among vaccinated participants, approximately 25% of them reported predominantly temporary changes in the menstrual cycle, however, we are unable to determine whether these changes are due to normal cycle variability. The COVID-19 vaccines are safe and effective for everyone, including pregnant people and people trying to conceive; hence, these findings should not discourage vaccination.

Association between RNAm-Based COVID-19 Vaccines and Permanency of Menstrual Cycle Alterations in Spanish Women: A Cross-Sectional Study. BIOLOGY 2022; 11:biology11111579. [PMID: 36358280 PMCID: PMC9687584 DOI: 10.3390/biology11111579] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 10/21/2022] [Accepted: 10/26/2022] [Indexed: 11/06/2022]
Abstract
Introduction: The purpose of this study was to delve more deeply into the medium and long-term relation between mRNA-based vaccines and changes in menstrual pain, cycle length, and amount of bleeding in Spanish women. Material and Methods: A total of 746 women (63% between 18−30 and 37% between 31−45 years old) participated in the study. A numerical rating scale was used for recording pain intensity, a pictorial chart for menstrual bleeding, and data from menstrual cycle duration, type of vaccine, number of doses and time from vaccination. Results: Sixty-five per cent of the women perceived changes in their menstrual cycle after receiving the vaccines, irrespective of type of vaccine or number of doses; all p values were >0.05. Most of them (n = 316 out of 484) reported more than one alteration in their menstrual cycle. Almost half of the participants had been vaccinated over 5 months (45%), 3−4 months (15%) 2−3 months (26%), and one month or less (13%) before. The percentage of women that reported alterations remained strongly constant across time, p > 0.05, ranging from 64 to 65%. Conclusions: Reported alterations in Spanish women after COVID vaccination remained more than 5 months after the last dose.

How Lifestyle Changes during the COVID-19 Global Pandemic Affected the Pattern and Symptoms of the Menstrual Cycle. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:13622. [PMID: 36294200 PMCID: PMC9602509 DOI: 10.3390/ijerph192013622] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 10/14/2022] [Accepted: 10/18/2022] [Indexed: 06/16/2023]
Abstract
This research investigated the implications that the COVID-19 pandemic had on the menstrual cycle and any contributing factors to these changes. A questionnaire was completed by 559 eumenorrheic participants, capturing detail on menstrual cycle symptoms and characteristics prior to and during the COVID-19 pandemic lockdown period. Over half of all participants reported to have experienced lack of motivation (61.5%), focus (54.7%) and concentration (57.8%). 52.8% of participants reported an increase in cycle length. Specifically, there was an increase in the median cycle length reported of 5 days (minimum 2 days, maximum 32 days), with a median decrease of 3 days (minimum 2 days and maximum 17 days). A lack of focus was significantly associated with a change in menstrual cycle length (p = 0.038) reported to have increased by 61% of participants. Changes to eating patterns of white meat (increase p = 0.035, decrease p = 0.003) and processed meat (increase p = 0.002 and decrease p = 0.001) were significantly associated with a change in menstrual cycle length. It is important that females and practitioners become aware of implications of environmental stressors and the possible long-term effects on fertility. Future research should continue to investigate any long-lasting changes in symptoms, as well as providing education and support for females undergoing any life stressors that may implicate their menstrual cycle and/or symptoms.

The effect of BNT162b2 SARS-CoV-2 mRNA vaccine on menstrual cycle symptoms in healthy women. Int J Gynaecol Obstet 2022; 160:313-318. [PMID: 35856178 PMCID: PMC9349849 DOI: 10.1002/ijgo.14356] [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: 02/07/2022] [Revised: 07/05/2022] [Accepted: 07/08/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVE To investigate the impact of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA BNT162b2 vaccine on women's menstrual cycle. METHODS In this questionnaire-based cross-sectional study, we assessed menstrual pattern and changes in women who completed the SARS-CoV-2 mRNA BNT162b2 vaccine 3 months before and after receiving the vaccine. Included were women aged 18-50 years without known gynecologic comorbidities who regularly monitor their menstruation through electronic calendars. All participants competed a detailed questionnaire on their menstrual symptoms including information on any irregular bleeding. To minimize bias, each woman served as a self-control before and after vaccination. Primary outcome was rate of irregular bleeding following vaccination and secondary outcome was presence of any menstrual change, including irregular bleeding, mood changes, or dysmenorrhea following the vaccine. RESULTS A total of 219 women met the inclusion critieria. Of them, 51 (23.3%) experienced irregular bleeding following the vaccine. Almost 40% (n = 83) of study participants reported any menstrual change following vaccination. Parity was positively asssociated with irregular bleeding with 26 (50%) of those suffering from irregular bleeding being multiparous compared with only 53 (31.5%) of women with no irregular bleeding (nulliparous 46% vs 60%, multiparous 50% vs 31%, rest 4% vs 8%, P = 0.049). The presence of medical comorbidities was also significantly higher among patients who experienced irregular bleeding (20.0% vs 6.0%, P = 0.003). CONCLUSION Our study shows relatively high rates of irregular bleeding and menstrual changes after receiving the SARS-CoV-2 mRNA BNT162b2 vaccine. Further research is needed to confirm our findings and to better characterize the magnitude of change and any possible long-term implications.

Menstrual abnormalities post-COVID vaccination: a cross-sectional study on adult Lebanese women. Ir J Med Sci 2022:10.1007/s11845-022-03089-5. [PMID: 35881229 PMCID: PMC9315076 DOI: 10.1007/s11845-022-03089-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 06/27/2022] [Indexed: 11/06/2022]
Abstract
Background In the year 2020, the coronavirus pandemic invaded the world. Since then, specialized companies began to compete, producing many vaccines. Coronavirus vaccines have different adverse events. Menstrual disorders have been noticed as a common complaint post-vaccination. Aim Our study fills an important gap by evaluating the relationship between coronavirus vaccines and menstrual disorders. Methods This is a cross-sectional study between 20 September 2021, and 1 October 2021, using an online survey. The questionnaire consisted of 36 questions divided into 4 sections: demographics, COVID-19 exposure and vaccination, hormonal background, and details about the menstrual cycle. Sample t-test, ANOVA test, chi-square, and McNemar test were used in bivariate analysis. Results This study includes 505 Lebanese adult women vaccinated against COVID-19. After vaccination, the number of women having heavy bleeding or light bleeding increased (p = 0.02 and p < 0.001, respectively). The number of women having regular cycles decreased after taking the vaccine (p < 0.001). Irregularity in the cycle post-vaccination was associated with worse PMS symptoms (p = 0.036). Women using hormonal contraception method or using any hormonal therapy had higher menstrual irregularity rates (p = 0.002 and p = 0.043, respectively). Concerning vaccine adverse events, those who had headaches had a higher rate of irregularity (p = 0.041). Those having PCOS, osteoporosis, or blood coagulation disorders had higher irregularity rate (p < 0.001 and p = 0.005, respectively). Conclusion Vaccine adverse events may include specific menstrual irregularities. Moreover, some hormonal medications and diseases are associated with the alteration of the menstrual cycle. This study helps in predicting vaccines’ menstrual adverse events, especially in a specific population prone to menstrual disorders.

Menstrual abnormalities after COVID-19 vaccines: A systematic review. VACUNAS 2022; 23:S77-S87. [PMID: 35873308 PMCID: PMC9294036 DOI: 10.1016/j.vacun.2022.07.001] [Citation(s) in RCA: 27] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 07/02/2022] [Indexed: 01/09/2023]
Abstract
The objective of this systematic review is to give a comprehensive interpretation of menstrual cycle changes after the COVID-19 vaccination. Additionally, it is imperative to assess reports of menstrual changes following vaccination to dispel concerns that COVID-19 vaccines hinder the likelihood of pregnancy in the long run. A literature review was conducted using digital databases to systematically identify the studies reporting any menstrual abnormalities after the COVID-19 vaccine. Detailed patient-level study characteristics including the type of study, sample size, administered vaccines, and menstrual abnormalities were abstracted. A total of 78 138 vaccinated females were included in this review from 14 studies. Of these, 39 759 (52.05%) had some form of a menstrual problem after vaccination. Due to the lack of published research articles, preprints were also included in this review. Menorrhagia, metrorrhagia, and polymenorrhea were the most commonly observed problems and the overall study-level rate of menstrual abnormality ranged from 0.83% to 90.9%. Age, history of pregnancy, systemic side-effects of COVID-19, smoking, and second dose of COVID-19 vaccine were predictors of menstrual problems after vaccination.

Menstrual symptoms variation among Lebanese women before and after the COVID-19 pandemic. Pharm Pract (Granada) 2022; 20:2699. [PMID: 36733514 PMCID: PMC9851823 DOI: 10.18549/pharmpract.2022.3.2699] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2022] [Accepted: 07/13/2022] [Indexed: 02/05/2023] Open
Abstract
Objectives Pandemic diseases and the confinement measures due to COVID-19 infection have introduced acute and persistent psychosocial stressors for different individuals with a greater influence on females manifested through changes in the menstrual cycle. The objective of this study was to assess Lebanese female of reproductive age about their menstrual cycle, their mental health, and their lifestyle, throughout the COVID-19 pandemic, Beirut blast, and the economic crises. Methods A cross-sectional online study conducted between October and December 2021, enrolled 398 Lebanese women using the snowball technique. The Menstrual Symptom Questionnaire (MSQ) was used to assess menstrual symptoms. A repeated measures ANOVA was used to assess factors associated with the variation in MSQ scores after vs before the pandemic. Results Our results showed that a significantly higher number of days of menses, number of pads per day and total MSQ score were significantly found after the pandemic compared to before it. More distress (Beta=0.68), more post-traumatic stress disorder due to COVID-19 (Beta=0.19), a higher number of waterpipes smoked per week (Beta=1.20) and being infected by COVID-19 compared to not (Beta=3.98) were significantly associated with an increase in the MSQ score after the pandemic compared to before it. Conclusion Our main findings indicate that females had irregular menstrual cycles, unpredictable bleeding pattern, and intense symptoms severity post COVID-19 pandemic. Furthermore, stress post COVID-19 and Beirut blast tended to be associated with increased menstrual symptoms. Thus, vulnerable women should be identified and offered appropriate care, information, and awareness regarding their menstrual period during a pandemic.

The Effect of COVID-19 on the Menstrual Cycle: A Systematic Review. J Clin Med 2022; 11:jcm11133800. [PMID: 35807090 PMCID: PMC9267255 DOI: 10.3390/jcm11133800] [Citation(s) in RCA: 40] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 06/19/2022] [Accepted: 06/28/2022] [Indexed: 01/17/2023] Open
Abstract
Researchers have been studying COVID-19 from day one, but not much is known about the impact of COVID-19 on the reproductive system, specifically the female reproductive system. There has been substantial anecdotal and media coverage on the effect of COVID-19 on the female reproductive system and changes in the menstrual cycle, but so far available data are not robust enough to draw firm conclusions about the topic. This article was carried out to present already published studies on the correlation between SARS-CoV-2 infection and menstrual cycle changes. A systematic literature search was conducted on the Medline, Scopus, and Cochrane Library databases in accordance with the PRISMA guidelines. Three studies were finally included in the review. The findings of the studies indicate changes in menstrual volume and changes in menstrual cycle length as consequences of SARS-CoV-2 infection; the latter was also the most common menstrual irregularity reported by the included studies. Women have mainly reported decreased menstrual volume and a prolonged cycle. The findings also indicate that the severity of COVID-19 does not play a role in menstrual cycle changes. However, the research on this topic is still too scarce to draw definitive conclusions, and there is a need for further research. The relevant conclusions, which could be drawn only from a well-constructed study, would have a major effect on defining the impact of SARS-CoV-2 infection on the menstrual cycle.

Self-Reported Menstrual Alterations During the COVID-19 Syndemic in Spain: A Cross-Sectional Study. Int J Womens Health 2022; 14:529-544. [PMID: 35444473 PMCID: PMC9013667 DOI: 10.2147/ijwh.s354655] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Accepted: 03/18/2022] [Indexed: 11/23/2022] Open
Abstract
Introduction Available evidence suggests that there might be an association between the stressors experienced during the COVID-19 syndemic and changes in menstrual patterns. The aim of this study was to assess self-reported menstrual alterations during the COVID-19 syndemic among women and people who menstruate aged 18-55 in Spain. Materials and Methods A cross-sectional online survey-based study was conducted (March-July 2021). Descriptive statistics were calculated and multivariate logistic regression models were constructed. This study was conducted as part of the "Equity and Menstrual Health in Spain" research project. Results Among participants (N=17,455), 39.4% reported menstrual alterations since the start of the syndemic. Participants self-reporting long COVID-19 presented higher odds of menstrual alterations (aOR: 1.34, 95% CI, 1.15-1.57). In participants with no history of COVID-19, the risk for self-reported menstrual alterations was significantly higher based on employment situation, among participants experiencing financial issues (eg, financial issues always/many times <12 months: aOR: 1.68, 95% CI, 1.48-1.90), poorer self-perceived health (eg, poor: aOR: 2.00, 95% CI, 1.31-3.07), and those diagnosed with polycystic ovary syndrome (aOR: 1.13, 95% CI, 1.02-1.26). Among participants with a self-reported COVID-19 diagnosis, factors that significantly increased the odds for menstrual alterations were experiencing financial strains (eg, financial issues always/many times <12 months: aOR: 1.53, 95% CI, 1.09-2.14), poorer self-perceived health (eg, poor: aOR: 3.09, 95% CI, 1.01-9.52). Overall, factors that decreased the odds of reporting menstrual alterations included age >25, being a carer, not having a gynecological condition and using hormonal contraception. Discussion and conclusions Findings suggest an impact of the COVID-19 syndemic on menstrual patterns. Social inequities in reporting menstrual alterations were identified. While the risk of reporting menstrual alterations was higher among participants with long COVID-19, evidence is not conclusive. Further research on menstrual health in the context of COVID-19 is needed, also to inform policy and practice.

[PMCID: PMC9683843 DOI: 10.1016/j.vacune.2022.10.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 07/02/2022] [Indexed: 06/28/2023]
Abstract
The objective of this systematic review is to give a comprehensive interpretation of menstrual cycle changes after the COVID-19 vaccination. Additionally, it is imperative to assess reports of menstrual changes following vaccination to dispel concerns that COVID-19 vaccines hinder the likelihood of pregnancy in the long run. A literature review was conducted using digital databases to systematically identify the studies reporting any menstrual abnormalities after the COVID-19 vaccine. Detailed patient-level study characteristics including the type of study, sample size, administered vaccines, and menstrual abnormalities were abstracted. A total of 78 138 vaccinated females were included in this review from 14 studies. Of these, 39 759 (52.05%) had some form of a menstrual problem after vaccination. Due to the lack of published research articles, preprints were also included in this review. Menorrhagia, metrorrhagia, and polymenorrhea were the most commonly observed problems and the overall study-level rate of menstrual abnormality ranged from 0.83% to 90.9%. Age, history of pregnancy, systemic side-effects of COVID-19, smoking, and second dose of COVID-19 vaccine were predictors of menstrual problems after vaccination.

Primary Dysmenorrhea Associated with Psychological Distress in Medical Sciences Students in The North of Iran: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2022; 16:224-229. [PMID: 36029061 PMCID: PMC9396007 DOI: 10.22074/ijfs.2022.542056.1216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND Primary dysmenorrhea is the usual medical status in medical students that are defined as pain<br />during the menstrual period. This study was done to evaluate the psychological problems associated with dysmenorrhea.<br />Materials and Methods: Three hundred forty students aged 18 to 20 years participated in this cross‑sectional<br />study (194 with dysmenorrhea and 150 without dysmenorrhea). In this cross‑sectional study, data were collected<br />through the sociodemographic checklist, the verbal multidimensional scoring system (VMS), and the revised<br />version of the Symptom Checklist-90 (SCL-90-R) questionnaire using the convenience sampling method. This<br />questionnaire includes 9 Subscale and a GSI index. We considered psychological distress to be equivalent to<br />the Global Severity İndex (GSI), which is obtained by dividing 90 questions by 90. The significance level of the<br />tests was considered 0.05.<br />Results: The GSI of the SCL-90 score in the 194 students with dysmenorrhea and 150 students without dysmenorrhea<br />was 1.02 ± 0.42 and 0.34 ± 0.15 respectively (P<0.001). In the group with dysmenorrhea, the severity<br />of dysmenorrhea was significantly associated with a family history of dysmenorrhea and mother's education<br />(P=0.012 and P=0.037, respectively). The strongest predictors of GSI>1 were a family history of dysmenorrhea<br />and mother's education [odds ratio (OR)=2.33, 95% confidence interval (CI), 1.43-4.15 and OR=0.45, 95% CI,<br />0.24-0.87, respectively].<br />Conclusion: According to the result, dysmenorrhea is associated with psychological distress. Psychological interventions<br />and counseling in addition to drug treatment are suggested for treatment of primary dysmenorrhea.<br />Therefore, it is necessary to formulate strategies and health policies to recover psychological issues of menstrual<br />health.

Infection with SARS-CoV-2 is associated with menstrual irregularities among women of reproductive age. PLoS One 2022; 17:e0276131. [PMID: 36288342 PMCID: PMC9604006 DOI: 10.1371/journal.pone.0276131] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Accepted: 09/29/2022] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Biological and psychological mechanisms may be responsible for menstrual irregularities occurring among women during the COVID-19 pandemic. STUDY DESIGN From January 2019 to September 2021, women (18- to 45-years-old and not using hormonal contraception) were recruited in Miami-Dade County, Florida. Cross-sectional, self-report surveys collected data on menstrual irregularities, COVID-19 vaccination, stress, depression, and loneliness. A EUA approved rapid test assay using whole blood measured SARS-CoV-2 IgG antibodies. Chi-square and Fisher's exact tests described menstrual irregularities among women recruited before versus after the start of the COVID-19 pandemic and with detectable versus undetectable SARS-CoV-2 IgG antibodies. A logistic regression examined the relationship between the presence of SARS-CoV-2 IgG antibodies and menstrual irregularities controlling for age, stress, depression, and loneliness. RESULTS Among 182 women enrolled, 73 were enrolled after pandemic onset, and 36 provided vaccination data. Having detectable SARS-CoV-2 IgG antibodies was associated with a higher percentage of menstrual irregularities among unvaccinated women (0% vs. 39%, p = .026) and among all women regardless of vaccination status (31% vs. 5%; p = .005). Adjusting for age and psychological variables, the odds of menstrual irregularities were 7.03 times (95% CI [1.39, 35.60]; p = .019) higher among women with detectable antibodies compared to women without detectable antibodies. Neither enrollment date, age, nor psychological factors were associated to menstrual irregularities. CONCLUSIONS Biological mechanisms related to SARS-CoV-2 infection may be responsible for irregular menstruation and should be further examined to mitigate the impact of the COVID-19 pandemic on women's health.

Effect of COVID-19 vaccination on the menstrual cycle. Front Med (Lausanne) 2022; 9:1065421. [PMID: 36590952 PMCID: PMC9802578 DOI: 10.3389/fmed.2022.1065421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Accepted: 11/22/2022] [Indexed: 12/23/2022] Open
Abstract
Numerous anecdotal accounts and qualitative research studies have reported on post-vaccination menstrual irregularities in women of reproductive age. However, none have quantified the impact. This is the first systematic review and meta-analysis to quantify and characterize the menstrual irregularities associated with vaccination for women of reproductive age. A search on July 20, 2022, retrieved articles published between December 1, 2019, and July 1, 2022, from MEDLINE, Embase, and Web of Science. The included articles were studies with full texts written in English that reported on menstrual irregularities for vaccinated vs. unvaccinated women of reproductive age. The quality of the studies was evaluated using the Study Quality Assessment Tool for Observation Cohort and Cross-Sectional Studies. Four observational studies were included. Review Manager was used to generating a forest plot with odds ratios (ORs) at the 95% confidence interval (CI), finding statistically significant associations between vaccination and menstrual irregularities for 25,054 women of reproductive age (OR = 1.91, CI: 1.76-2.07) with a significant overall effect of the mean (Z = 16.01, p < 0.0001). The studies were heterogeneous with significant dispersion of values (χ2 = 195.10 at df = 3, p < 0.00001, I 2 = 98%). The findings of this systematic review and meta-analysis are limited by the availability of quantitative data. The results have implications for treating women of reproductive age with menstrual irregularities and informing them about the potential side effects of vaccinations.

Magnitude and associated factors of menstrual irregularity among undergraduate students of Debre Berhan University, Ethiopia. Reprod Health 2021; 18:101. [PMID: 34020676 PMCID: PMC8139046 DOI: 10.1186/s12978-021-01156-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Accepted: 05/11/2021] [Indexed: 11/10/2022] Open
Abstract
Background Menstrual irregularity is a common problem among women aged from 21 to 25years. Previously published work on menstrual irregularity used inconsistent definition which results in a difference in prevalence. Therefore the study aimed to assess the magnitude and associated factors of menstrual irregularity among undergraduate students of Debre Berhan University, Ethiopia. Methods A cross-sectional study design was carried out among 660 undergraduate female students at Debre Berhan University. To get representative study participants, a stratified sampling technique was used. To collect the data self-administered questionnaire was used. Physical examination and anthropometric measurement were also done. Data were analyzed by using SPSS version 21. Logistic regression analysiswas done. A significant association was declared at a p-value less than 0.05. Result A total of 620 students participated in the present study with a response rate of 93.9%. Out of the total study participants, 32.6% (95% CI 2936.5) participants had irregular menstrual cycle. Significant association was found between anemia (AOR=2.1; 95%CI 1.3373.441), alcohol intake (AOR=2.4; 95%CI 1.254.666),<5 sleep hours (AOR=5.4; 95%CI 2.9759.888), 67 sleep hours (AOR=1.9; 95%CI 1.2912.907), Perceived stress (AOR=3.3; 95%CI 1.83225.940), iodine deficiency disorder (IDD) (AOR=3.9; 95%CI 1.32511.636) and underweight (AOR=1.8; 95%CI 1.1092.847) with menstrual irregularity. Conclusion The finding of this study reported a low magnitude of menstrual irregularity as compared to previous studies. Students should adopt healthier lifestyle practices (weight control, stress control, anemia control, and avoid alcohol intake) to control menstrual irregularity. Menstrual irregularity is a common problem among university students. It affects their daily activities. But it lacks attention, especially in developing countries. Additionally, menstrual irregularity is defined differently by different researchers which results in a difference in prevalence. So it is difficult to compare. Therefore this study aims to assess the magnitude and associated factors of menstrual irregularity among undergraduate students of Debre Berhan University, Ethiopia. To avoid the inconsistent definition of menstrual irregularity which is used by different researchers, we used the standard of menstrual irregularity definition which was prepared by the international federation of obstetrics and gynecologist in 2018. This study uses across sectional study design among 660 undergraduate students of Debre Berhan University, Ethiopia. A self-administered questioner which includes socio-demographic data, menstrual-related questions, lifestyle and behavioral questions, and medical history questions were used to collect data. Besides, physical examination and anthropometric measurement were done. Of a total 620 students who participated in the study: 202 (32.6%) had menstrual irregularity. Factors that had significant association with menstrual irregularity were, anemia (AOR=2.1; 95%CI 1.3373.441), alcohol intake (AOR=2.4; 95%CI 1.254.666),<5 sleep hours (AOR=5.4; 95%CI 2.9759.888), 67 sleep hours (AOR=1.9; 95%CI 1.2912.907), Perceived stress (AOR=3.3; 95%CI 1.83225.940), iodine deficiency disorder (IDD) (AOR=3.9; 95%CI 1.32511.636) and underweight (AOR=1.8; 95%CI 1.1092.847). In conclusion, the finding of this study reported a low magnitude of menstrual irregularity as compared to previous studies.

Health issues and healthcare utilization among adults who reported exposure to tear gas during 2020 Portland (OR) protests: a cross-sectional survey. BMC Public Health 2021; 21:803. [PMID: 33902512 PMCID: PMC8074355 DOI: 10.1186/s12889-021-10859-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Accepted: 04/16/2021] [Indexed: 01/26/2023] Open
Abstract
Background Repeated use of chemical irritants for crowd-control by local and federal law enforcement during sustained racial justice protests in the U.S. has raised concerns about potential adverse health effects. The objective of this study was to describe the health consequences of exposure to tear gas agents and associated healthcare utilization among adults reporting recent exposure to tear gas. Methods A cross-sectional, self-administered web-based survey of a convenience sample of 2257 adults reporting recent exposure to tear gas in Portland, Oregon (U.S.), administered between July 30, 2020-August 20, 2020. Descriptive analyses were conducted on socioeconomic characteristics, reported health issues, utilization of healthcare services, and frequency of reported exposure to tear gas. Associations between reported mental health issues, healthcare utilization and race and/or ethnic categories were assessed using a chi-square test. For tests of association, racial and/or ethnic categories were divided into White/Non-Hispanic only and all other racial/ethnic categories due to a small number of Black, American Indian or Alaska Native, Asian/Pacific Islander, Hispanic participants and participants with multiple race and/or ethnic background. Effect sizes for the differences were expressed as Cramer’s V, a metric that measures associations between nominal responses. The Cochran-Armitage trend test was used to assess the relationship between health issues and the number of reported days of exposure to tear gas (i.e., a proxy dose of exposure) grouped into 1 day, 2–4 days, and ≥ 5 days. Missing data (item non-response) were omitted from the analysis. Results Almost all respondents (2116; 93.8%) reported physical (2114; 93.7%) or psychological (1635; 72.4%) health issues experienced immediately after (2105; 93.3%) or days following (1944; 86.1%) the exposure. A slightly higher proportion experienced delayed head or gastrointestinal tract issues compared with immediate complaints. The majority (1233; 54.6%) reported receiving or planning to seek medical or mental care. We observed a positive exposure-response trend for all except mouth-related delayed issues (p < 0.01). Conclusion Persons who reported exposer to tear gas agents also reported physical and psychological health issues over a multiple-day period. Health issues reported increased with the frequency of reported exposure, indicating a potential dose-response; these health effects often led to healthcare utilization. This study provides evidence of potential unexpected harms of tear gas in civilians.

Timing of breast cancer surgery during the menstrual cycle-is there an optimal time of the month? Oncol Lett 2020; 20:2045-2057. [PMID: 32782523 PMCID: PMC7400969 DOI: 10.3892/ol.2020.11771] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Accepted: 04/21/2020] [Indexed: 12/23/2022] Open
Abstract
An intriguing relationship between menstrual cycle phase at the time of breast cancer surgery and clinical outcomes was first proposed in the late 1980s. Despite a number of clinical studies conducted to address this, as well as meta-analyses and systematic reviews, there remains significant controversy surrounding the effect of menstrual cycle phase at time of surgery on the prognosis of premenopausal breast cancer. While some studies have suggested that surgery performed during the luteal phase results in the most favourable outcome, other studies report the follicular phase is more favourable, and others show no association. Given the conflicting results, there remains insufficient evidence to determine whether there is an optimal time of the month to perform surgery. This issue has dogged breast cancer surgery for decades; knowledge of an optimal time of the month to conduct surgery would be a simple approach to improving patient outcomes. This review explores the potential biological mechanisms through which the hormonal milieu might contribute to differences in prognosis, and why clinical findings are so variable. It is concluded that a significant problem with current clinical research is the lack of insight from mechanistic studies. While there are a number of plausible biological mechanisms that could lead to altered survival, supporting evidence is limited. There are also variable approaches to defining the menstrual cycle phase and hormone receptor status of the tumour and few studies controlled for prognostic factors such as tumour size and stage, or addressed the impact of adjuvant treatments. Elucidation of the specific confounding factors, as well as biological mechanistic pathways that could explain the potential relationship between timing of surgery and survival, will greatly assist in designing robust well-controlled prospective clinical studies to evaluate this paradigm.

Abstract
Regularity, length of the cycle and duration of menstrual flow are a reflection of women health. The purpose of the research was to assess the relationships between socioeconomic status, cycle length, duration of menses, regularity and dysmenorrhea. A survey was conducted among 896 healthy women from Łódź and Warsaw (Poland), aged 15.71–26.98. Women who were menarche at least 3 years ago were asked to complete the survey. Women were asked about cycle length (number of days), duration of menstrual flow, regularity of the cycle, dysmenorrhea, birth place, parental education level, attendance at physical education classes, participation in additional sports activities, self-assessment of stress levels at home and at school/university, and smoking. For data analysis, t-test, analysis of variance, and chi-square were used, and p<0.05 was considered to be statistically significant. There were no significant relationships between the mean cycle length, regularity and the environmental factors, except for differences in the average length of the menstrual cycle in women from Łódź who attend additional sports activities. Women who are more physically active are characterized by a shorter menstrual cycle. In terms of the length of the menstrual flow, daughters of better educated fathers were characterized by longer menses. In contrast, dysmenorrhea was associated with longer menstrual periods and longer menstrual bleeding, as well as with higher levels of stress, both at home and at school. Environmental factors affected the features of menstruation cycles in women from Central Poland.

Abstract
This population-based cross-sectional study investigated the association between menstrual cycle irregularity and tinnitus in premenopausal Korean women. We used data from the 5th Korea National Health and Nutrition Examination Survey (2010-2012). A total of 4633 premenopausal women were included. Hierarchical multivariable logistic regression analysis was performed. Individuals with tinnitus accounted for 21.6%. Women with tinnitus or menstrual irregularity had significantly higher rates of stress, depressive mood, and suicidal ideation than those without. The proportion of individuals with irregular menstrual cycles with duration of longer than 3 months increased as the severity of tinnitus increased (P = 0.01). After adjusting for confounding variables, the odds of tinnitus increased in individuals with irregular menstrual cycles compared to those with regular menstrual cycles. The odds ratios (ORs) of tinnitus tended to increase as the duration of menstrual irregularity became longer (1.37, 95% confidence interval: 1.06-1.78 for duration of up to 3 months; 1.71, 1.03-2.85 for duration of longer than 3 months, P for trend = 0.002). Our study found a positive association between menstrual cycle irregularity and tinnitus. Menstrual cycle irregularity may be a related factor of tinnitus in women with childbearing age.

Abstract
This study was performed to assess the relationship between menstrual irregularity and dental pain or chewing discomfort in women before menopause, using nationally representative data. This study analyzed 4595 participants who were ≥19 years or older, and did not have missing values for outcome variables from the Korean National Health and Nutrition Examination Survey. Tooth pain was considered present if the participant felt throbbing discomfort, pain, or sensitivity when eating hot or cold food or drinking hot or cold beverages. Self-reported oral chewing discomfort was obtained. Adjusted odds ratios and their 95% confidence intervals for tooth pain in the individuals with menstrual cycle irregularity were 1.30 (1.05, 1.62) after adjustment for age, body mass index, drinking, smoking, income, exercise, stress, metabolic syndrome, and the frequency of tooth brushing. Adjusted odds ratios and their 95% confidence intervals for chewing discomfort in the individuals with menstrual cycle irregularity were 1.33 (1.03, 1.72) after adjustment. The association between menstrual irregularity and dental pain or chewing discomfort in women before menopause was proven—after adjusting for confounding factors—by multiple logistic regression analyses. Menstrual cycle irregularity may be considered a potential risk indicator for dental pain or chewing discomfort in Korean women before menopause.

Abstract
Background A regular menstrual cycle is an important indicator of a healthy reproductive system. Previous studies reported obesity, stress, and smoking as the factors that are associated with irregular menstruation and early menopause. However, the integrative effects of these modifiable risk factors have not been fully understood. This study aimed to investigate the modifiable risk factors of menstrual cycle irregularity and premature menopause, as well as their individual and combined effects among adult women in Korea. Method This study selected adult women aged 19 years and above who had been included in the 2007–2014 Korean National Health and Nutrition Examination Survey. We used a separate dataset to analyze the risk factors of menstrual cycle irregularity and menopause (pre- and postmenopausal women: n = 4788 and n = 10,697, respectively). Univariate and multiple logistic regression analyses were conducted to evaluate the effects of smoking, drinking, obesity, and perceived level of stress on the menstrual cycle and menopause. Both logit and linear models were used in the analyses of the association between smoking and menopausal age. Equivalized household income, marital status, and educational level were considered as covariates. The modifiable risk factor scores were also calculated to integrate the effect of smoking, drinking, and obesity in the analysis. Result Results showed that smoking status, pack-year, obesity, and perceived level of stress were significantly associated with irregular menstruation among premenopausal women. Especially, women demonstrating > 3 modifiable risk factor scores had 1.7 times higher risk of having irregular menstruation than those who had a 0 score. Meanwhile, early initiation of smoking (≤19 years) and high pack-year (≥5) were also significantly associated with premature menopause among postmenopausal women. Conclusion This study demonstrated that modifiable risk factors, such as smoking, obesity, and stress, were significantly associated with menstrual cycle irregularity. Lifetime smoking was also correlated with early menopause. Our results suggested that healthier lifestyle practices, including, cessation of smoking, weight control, and stress management, were important factors in improving the reproductive health of women throughout life.

Abstract
BACKGROUND Menstrual irregularity is an indicator of endocrine disorders and reproductive health status. It is associated with various diseases and medical conditions, including obesity and underweight. We aimed to assess the association between body weight changes and menstrual irregularity in Korean women. METHODS A total of 4,621 women 19 to 54 years of age who participated in the 2010 to 2012 Korea National Health and Nutrition Examination Survey were included in this study. Self-reported questionnaires were used to collect medical information assessing menstrual health status and body weight changes. Odds ratios (ORs) and 95% confidence interval (CI) were calculated to evaluate the association between body weight changes and menstrual irregularity. RESULTS Significantly higher ORs (95% CI) were observed in the association between menstrual irregularity and both weight loss (OR, 1.74; 95% CI, 1.22 to 2.48) and weight gain (OR, 1.45; 95% CI, 1.13 to 1.86) after adjusting for age, body mass index, current smoking, heavy alcohol drinking, regular exercise, calorie intake, education, income, metabolic syndrome, age of menarche, parity, and stress perception. Of note, significant associations were only observed in subjects with obesity and abdominal obesity, but not in non-obese or non-abdominally obese subjects. U-shaped patterns were demonstrated in both obese and abdominally obese subjects, indicating that greater changes in body weight are associated with higher odds of menstrual irregularity. CONCLUSION We found a U-shaped pattern of association between body weight changes and menstrual irregularity among obese women in the general Korean population. This result indicates that not only proper weight management but also changes in body weight may influence the regulation of the menstrual cycle.
