Prevalence of dysmenorrhea and predictors of its pain intensity among Palestinian female university students

The effect of hot application with cherry seed belt on dysmenorrhoea: A randomized controlled trial

BACKGROUND

This randomized controlled experimental study was conducted to determine the effect of application of a heated cherry seed belt on dysmenorrhoea. There is a need to test the effects of experimental studies worldwide that have conducted interventions to improve the quality of life of women with dysmenorrhoea.

METHODS

This study included 55 female university students. Students were diagnosed with primary dysmenorrhoea by a specialist hospital physician. The students in the intervention group heated the cherry seed belt in a microwave oven for 3 min, and wrapped it around their lower abdomen for 30 min once per day for 3 days: 4 days before menstruation, on the first day of menstruation and on the last day of menstruation. They also took dexketoprofen trometamol 25 mg (an analgesic) once daily for 5 days, starting 2 days before menstruation, with an additional tablet on the last day of menstruation (total of six tablets per cycle). The control group received dexketoprofen trometamol 25 mg alone. All students recorded their pain scores in a dysmenorrhoea follow-up form, measured with a visual analogue scale, before and 30 min after the intervention for three menstrual cycles.

RESULTS

Before application pain scores and menstruation symptom scale pain symptoms were significantly higher in the intervention group than in the control group (p < 0.05). The intervention group stated that application of the heated cherry seed belt was effective for dysmenorrhoea. Average satisfaction was 7.3.

CONCLUSIONS

As a result, although there was no significant difference in terms of VAS scores between the intervention and control groups, except for one measurement, the intervention group was satisfied with the heated cherry seed belt for treatment of dysmenorrhoea.

The effect of aromatherapy intervention with Bergamot and Grapefruit essential oils on premenstrual syndrome and menstrual symptoms: a randomized controlled trial

BACKGROUND

Premenstrual syndrome and menstrual symptoms adversely affect approximately 80-95% of women of reproductive age. Aromatherapy interventions are used to reduce premenstrual syndrome and menstrual symptoms. This study was conducted to determine the effect of aromatherapy intervention with bergamot and grapefruit essential oils on premenstrual syndrome and menstrual symptoms.

METHODS

Ninety women with premenstrual syndrome were included the study. Participants were randomly divided into 3 groups: Bergamot(n = 30), Grapefruit(n = 30), Placebo(n = 30). Participants in each group were made to smell pure essential oil for 30 min 3 times a day for 4 days during the luteal phase of the menstrual cycle. The used was repeated in 3 menstrual cycles. "Premenstrual Syndrome Scale (PMSS)" was used to evaluate premenstrual syndrome and "Menstrual Symptom Questionnaire (MSQ)" was used to evaluate menstrual symptoms. All measurements were performed before and after the study.

RESULTS

The results showed that grapefruit essential oil was effective in reducing PMSS total score (p = 0.010) and sub-scale scores (depressive affect, anxiety, fatigue, depressive thoughts, appetite changes, sleep changes and bloating (p < 0.001), irritability (p = 0.024), pain (p = 0.047)). Although grapefruit essential oil had no effect on the total score of the MSQ. Grapefruit essential oil was found to be effective in reducing the MSQ scale sub-scale scores (menstrual pain symptoms (p = 0.024) and the use of coping methods with menstrual pain (p = 0.011)). Bergamot essential oil was found to be effective in reducing PMSS total score (p = 0.001) and PMSS sub-scale scores depressive affect (p = 0.013), irritability (p = 0.034), depressive thoughts and appetite changes (p = 0.026), pain (p = 0.001)). In addition, there was no effect on the menstrual syndrome scale and its sub-dimensions (p > 0.05).

CONCLUSION

Grapefruit essential oil was effective in reducing both premenstrual syndrome and menstrual symptoms, whereas bergamot essential oil was only effective in reducing premenstrual symptoms.

Burden, impacts and management practices of dysmenorrhea among female students in Ethiopia: a systematic review and meta-analysis

Dysmenorrhea is a public health problem worldwide, and affects more than half of reproductive-age females in Ethiopia. Despite dysmenorrhea having being studied, this has not covered the impacts and management of dysmenorrhea. Therefore, this review aimed at critically appraising, synthesizing and presenting the evidence on the burden, impacts and management methods of dysmenorrhea among females in Ethiopia. International databases (SCOPUS, CINAHL, CAB Abstract, EMBASE, PubMed, Web of Science, Google and Google Scholar) and lists of references were employed to search literature in Ethiopia. The overall burden of dysmenorrhea was presented using a random-effects model for the reported proportion by forest plot using STATA version 18. The heterogeneity of the studies was determined using p=0.05 for I2 statistics. In addition, sensitivity analyses were performed to examine the stability of pooled values in the presence of outliers. Furthermore, Egger's regression test and funnel plot were performed to check for potential publication bias. A total of 20 studies and a population of 8713 were included in the review. The overall burden of dysmenorrhea among females was 73% (95% CI 68 to 77%), with I2=96.04. Psychological problems (59.9%), poor concentration (42.3%) and absenteeism from the class (41.3%) were the common impacts of dysmenorrhea, and bed rest (54%), use of painkillers (41.5%) and hot drinks (41.3%) were commonly practiced treatments by participants. Around three out of four females experienced dysmenorrhea. Enhancing social support may reduce stress; and behavioral interventions such as mind-body awareness and relaxation training are believed to help decrease the risk of depression by alleviating dysmenorrhea. Both pharmacological and non-pharmacological therapy have played a crucial role in its management. But the literature offers controversial scientific proof, and imply that high-quality trials are needed to make conclusive recommendations for better management methods of dysmenorrhea.

Exploration of the relationship between primary dysmenorrhea, pain perception, and menstruation-related quality of life in young women: a cross-sectional observational study

Background

This study explores the relationship between primary dysmenorrhea (PD), pain, pain catastrophizing, and menstruation-related quality of life in young women.

Methods

A cross-sectional study was conducted involving 44 young women, both with and without PD. Various variables including pain intensity, pain catastrophizing, and menstruation-related quality of life were assessed using validated questionnaires. Correlation and regression analyses were performed to examine the relationships between the variables.

Results

Significant associations were found between the presence of PD, tendency to catastrophize pain, and decreased menstruation-related quality of life. A high correlation was observed between pain intensity and catastrophizing, indicating mutual influence between these variables. Menstruation-related quality of life was affected in terms of health perception, psychological aspect, and symptoms among women with PD. The linear regression model demonstrated that catastrophizing explained 42.8% of the variance in menstruation-related quality of life.

Conclusions

These findings underscore the importance of addressing dysmenorrhea in young women, as it significantly impacts their quality of life related to menstruation. Understanding the factors contributing to dysmenorrhea and its effects on quality of life can inform more effective, patient-centered treatment strategies.

Study on the influencing factors of primary dysmenorrhea in female college students: Systematic review and meta-analysis

BACKGROUND

The influencing factors of primary dysmenorrhea in female college students were analyzed through meta-analysis to provide the corresponding basis for its prevention and treatment.

METHODS

The databases, including China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, VIP database, China Biology Medicine Disc, Pubmed, Embase, Cochrane library, and Web of science were searched for the literature on the influencing factors of primary dysmenorrhea in female college students was retrieved from the science database from the establishment of the database to July 17, 2023. The Newcastle-Ottawa Quality Scale was used to score the quality of cohort and case-control studies included in the study. The cross-sectional studies were scored by the Agency for Healthcare Research and Quality. Two researchers independently screened the literature, and if there was no consensus, the third party would make a judgment on whether to include the literature. The extracted content included the first author, publication year, country, study type, sample size, and influencing factors. Stata17.0 software was used for meta-analysis.

RESULTS

A total of 23 studies were included, with a total sample size of 18,080 cases. Current evidence shows that the prevalence of primary dysmenorrhea in female college students is 70.3% (95%CI: 62.7-77.9%), and the combined odd ratio values (95%CI) of the main influencing factors are: family history of dysmenorrhea 2.116 (1.613-2.776), early age at menarche 2.200 (1.392-3.477), irregular menstrual cycle 1.662 (1.166-2.367), drinking cold drinks 1.717 (1.220-2.417), high caffeine intake 2.082 (1.379-3.144), stress 1.895 (1.515-2.282), medical specialty 1.827 (1.365-2.445), and adequate sleep 0.328 (0.232-0.463).

CONCLUSION

The prevalence of primary dysmenorrhea is high in female college students, and adequate sleep is a protective factor for primary dysmenorrhea. Family history of dysmenorrhea, early age at menarche, irregular menstrual cycle, drinking cold drinks, high caffeine intake, stress, and medical specialty were all risk factors.

Comparison of the Effects of Inappropriate Meal Timing-Induced and Genetic Models of Circadian Clock Disruption on Uterine mRNA Expression Profiles

BACKGROUND

Accumulating evidence reveals that inappropriate meal timing contributes to the development of lifestyle-related diseases. An underlying mechanism is thought to be the disruption of the intracellular circadian clock in various tissues based on observations in both systemic and tissue-specific clock gene-deficient mice. However, whether the effects of conditional clock gene knockout are comparable to those of inappropriate meal timing remains unclear.

OBJECTIVES

This study aimed to compare the effects of a recently developed 28-h feeding cycle model with those of a core clock gene Bmal1 uterine conditional knockout (Bmal1 cKO) model on uterine mRNA expression profiles.

METHODS

The models were generated by subjecting C57BL/6J mice to an 8-h/20-h feeding/fasting cycle for 2 wk and crossing Bmal1-floxed mice with PR-Cre mice. Microarray analyses were conducted using uterine samples obtained at the beginning of the dark and light periods.

RESULTS

The analyses identified 516 and 346, significantly 4-fold and 2-fold, up- or downregulated genes in the 28-h feeding cycle and Bmal1 cKO groups, respectively, compared with each control group. Among these genes, only 7 (1.4%) and 63 (18.2%) were significantly up- or downregulated in the other model. Moreover, most (n = 44, 62.9%) of these genes were oppositely regulated. These findings were confirmed by gene set enrichment analyses.

CONCLUSIONS

This study reveals that a 28-h feeding cycle and Bmal1 cKO differently affect gene expression profiles and highlights the need for considering this difference to assess the pathophysiology of diseases associated with inappropriate meal timing.

Impact of daily breakfast intake on the outcomes of assisted reproductive technology procedures

OBJECTIVE

To assess the relationship between meal consumption frequency and assisted reproductive technology (ART) outcomes among female patients with infertility.

RESEARCH METHODS & PROCEDURES

This cohort study was conducted from February 2022 to January 2024 at Tokyo Medical University Hospital. Overall, 101 female patients with infertility issues and without a history of stroke, heart disease, cancer, or type 1 or type 2 diabetes were enrolled in this study. The factors extracted from the questionnaire included demographic information, meal consumption frequency before ART and at 20 years of age, smoking status, and alcohol consumption status. Data on other factors, including age, body mass index, anti-Müllerian hormone level, and parity history, were collected from medical records. The assessed clinical outcomes included number of transplanted embryos, clinical pregnancies, ongoing pregnancies, live births, and miscarriages.

RESULTS

After adjusting for potential confounding factors, including age, smoking status, alcohol consumption status, body mass index, anti-Müllerian hormone level, and parity history, a multivariate analysis of ART outcomes was performed. Patients were categorized into groups based on the frequency of weekly consumption of breakfast, lunch, and dinner. Patients who consumed breakfast 6-7 times a week were significantly more likely to have higher rates of live birth and lower rates of miscarriage in pregnancies conceived through ART.

CONCLUSIONS

Consumption of breakfast 6-7 times a week before ART was associated with increased success rates following ART. This highlights the potential importance of regular breakfast consumption for optimizing ART outcomes.

Prevalence and risk factors of primary dysmenorrhoea among medical students: a cross-sectional survey in Indonesia

OBJECTIVES

This study aimed to assess the prevalence and associated risk factors of primary dysmenorrhoea among medical students in Indonesia.

DESIGN

A web-based survey was conducted among 630 medical students across Indonesia, selected based on specific inclusion criteria. Dysmenorrhoea prevalence, severity and associated risk factors were assessed using a self-reported questionnaire. To analyse the data, univariate and multiple binary logistic regression analyses were performed. A significance level of 5% (p<0.05) was used for both types of analyses to determine the statistical significance of the observed associations.

SETTING AND PARTICIPANTS

Indonesia (2021: n=630 female medical students).

OUTCOMES

The primary outcome is primary dysmenorrhoea, defined as painful menses without previous diagnosis of pelvic pathology. The severity of dysmenorrhoea was measured using the Verbal Multidimensional Scoring System. Independent variables include socio-demographic characteristics, menstrual history and other identified associated risk factors.

RESULTS

Of the 630 Indonesian medical students surveyed, a large proportion (91.27%) reported experiencing dysmenorrhoea, with 52.35% experiencing moderate-to-severe pain. Family history of dysmenorrhoea emerged as a significant predictor for both occurrence (OR 3.76; 95% CI 1.89 to 7.45) and severity (OR 1.47; 95% CI 1.04 to 2.06). Dysmenorrhoea severity was positively associated with cycle length (OR 1.57; 95% CI 1.01 to 2.43), whereas higher body mass index (BMI) (OR 0.94; 95% CI 0.90 to 0.98) and being Indonesian of foreign descent (OR 0.46; 95% CI 0.27 to 0.84) were negatively associated with moderate-to-severe dysmenorrhoea.

CONCLUSIONS

Dysmenorrhoea is prevalent among Indonesian medical students, with family history, BMI, cycle length and race significantly associated with its occurrence or severity. These findings underscore the need for further research on more diverse populations to enhance awareness and address this prevalent gynaecological concern effectively.

Dysmenorrhea and Its Impact on Patients' Quality of Life-A Cross-Sectional Study

Background: Dysmenorrhea is a common condition that may have negative effects on social life, couples' relationships and professional activities. The objectives of this study were to evaluate the prevalence, risk factors and characteristics of dysmenorrhea and its impact on patients' quality of life using a specific self-questionnaire named "DysmenQoL questionnaire". We also checked the validity and reliability of this questionnaire in our population. Methods: We conducted a cross-sectional study that included 504 participants of reproductive age between 18 and 45 years of age. The data were collected with an original form divided into three sections. The last section (DysmenQoL questionnaire) included 20 statements scored from 1 ("never") to 5 ("every time") that evaluates the effects of menstrual pain on health and feelings, daily activities, relationships and professional activity. We calculated the sum of the scores for each statement and we called it the "DysmenQoL score". Results: The prevalence of dysmenorrhea was 83.7%. The presence of dysmenorrhea was statistically significant associated with the degree of menstrual bleeding (p = 0.017), the presence of infertility (p = 0.034) and dyspareunia (p = 0.002), but also with the presence of premenstrual syndrome and a family history of dysmenorrhea (p < 0.001). Among the participants with dysmenorrhea, 73.9% considered that this symptom affected their quality of life, and this was correlated with pain intensity and the DysmenQoL score (p < 0.001). A significant difference regarding the DysmenQoL score depending on the pain intensity, frequency and duration of dysmenorrhea and the methods used to reduce the pain was observed. Conclusions: Dysmenorrhea had a high prevalence among the participants included in the study, and its presence was associated with a series of risk factors. Most women considered that dysmenorrhea affected their quality of life. The DysmenQoL questionnaire proved to be a reliable and valid method for evaluating the impact of dysmenorrhea on quality of life.

Social Determinants of Health and Dysmenorrhea: A Systematic Review

Social determinants of health play a key role in health disparities. Dysmenorrhea is a highly prevalent and impactful public health problem affecting reproductive-age females. Systematically examining social determinants of health (SDoH) in dysmenorrhea is important for identifying gaps in the literature and informing research, policy, and clinical practice to reduce the public health burden associated with dysmenorrhea. The purpose of this systematic review was to synthesize the literature on SDoH and dysmenorrhea. The review protocol was prospectively registered. We searched Medline, EMBASE, CINAHL, PsycINFO, Scopus, and Google Scholar through February 2024 using search strategies informed by the literature. Screening of the articles, data extraction, and risk-of-bias (RoB) assessment were conducted independently by at least 2 reviewers on the Covidence platform. Among 2,594 unique records screened, 166 met eligibility criteria and were included for data extraction and RoB assessment. Evidence suggests traumatic experiences, toxic environmental exposures, female genital mutilation, job-related stress, lack of menstrual education, and low social support were associated with worse dysmenorrhea outcomes. However, evidence was equivocal regarding the relationships between dysmenorrhea outcomes and SDoH factors, including socioeconomic status, geographical location, race/ethnicity, employment, and religion. Nearly all articles (99.4%) had a high or very high overall RoB. The relationships between SDoH and dysmenorrhea outcomes were often inconsistent and complicated by heterogeneous study populations and methodologies. More rigorous research examining SDoH in dysmenorrhea is needed to inform policy and clinical practice. PERSPECTIVE: This systematic review synthesizes evidence linking SDoH and dysmenorrhea. The relationships between SDoH and dysmenorrhea were often equivocal and complicated by heterogeneous study populations and methodologies. We identify directions for future research and SDoH factors that could be addressed clinically (eg, trauma, menstrual education, and occupational stress).

Adolescent dysmenorrhoea in general practice: tensions and uncertainties

This Perspectives article reflects on findings from our systematic review about adolescent dysmenorrhoea Q, drawing on sociology of diagnosis theory. We consider tensions and uncertainties between presentation with symptoms of dysmenorrhoea and processes of symptom categorisation and diagnosis in adolescents, tracing these through research and clinical guidance, considering possible implications for clinical practice. We argue that challenges in distinguishing between primary and secondary dysmenorrhoea in research translate into challenges in differentiation in clinical practice. We argue that framing this distinction as clear cut and straightforward belies the well-documented challenges in diagnosis of endometriosis, and that not recognising uncertainty and complexity inherent in this task may benefit neither clinicians nor patients.

Determinants of dysmenorrhoea among female adolescents: results from a community-based cohort study in Amsterdam

RESEARCH QUESTION

What is the contribution of sociodemographic, psychosocial, lifestyle and reproductive factors up to the age of 11-12 years to the occurrence of dysmenorrhoea at age 15-16 years within the Amsterdam Born Children and their Development (ABCD) study?

DESIGN

Data of 1038 female adolescents were used. Participants' baseline characteristics were obtained using self-reported questionnaires up to the age of 11-12 years, as well as the obstetric information of their mothers during pregnancy. Dysmenorrhoea was assessed at the age of 15-16 years, and was deemed to be present if an adolescent reported menstrual abdominal and/or back pain and therefore took medication and/or hormonal contraception. Using a backward selection approach, potential determinants of dysmenorrhoea were selected and multivariable associations were determined.

RESULTS

The overall prevalence of dysmenorrhoea was 49.5% among the participants. Intake of 3-4.5 sugar-sweetened beverages/day (P = 0.035) and higher gynaecological age (i.e. years since menarche) (P < 0.001) were significantly associated with higher occurrence of dysmenorrhoea in the final model, which explained 8.1% of the total variance in the occurrence of dysmenorrhoea. No significant associations were found between the occurrence of dysmenorrhoea and sociodemographic or psychosocial factors.

CONCLUSIONS

This investigation of various potential risk factors for dysmenorrhoea suggests that diet and reproductive factors are particularly important predictors of the occurrence of dysmenorrhoea among young adolescents. Specifically, intake of sugar-sweetened beverages and higher gynaecological age were predictive of the occurrence of dysmenorrhoea. Other lifestyle factors were also identified as possible risk factors. Using this knowledge, effective strategies can be developed to reduce the burden of dysmenorrhoea among adolescents, and to provide appropriate care for those suffering from the condition.

The hidden burden of dysmenorrhea among adolescent girls in Palestine refugee camps: a focus on well-being and academic performance

BACKGROUND

Dysmenorrhea (painful menstruation) is a condition that may have a profound effect on adolescent girls' health status and well-being. It can impede their engagement in daily activities and hamper their regular school attendance. This study aims to explore the relationship between dysmenorrhea, well-being, and academic performance among adolescent girls living in Palestine refugee camps in the West Bank and Jordan.

METHODS

We conducted a household survey between June and September 2019, with a total sample of 2737 adolescent girls 15 to 18 years old. Dysmenorrhea severity was assessed using the Working Ability, Location, Intensity, Duration of pain Dysmenorrhea scale (WaLIDD). The WHO-5 scale was used to evaluate the girls' overall well-being. Menstrual academic disruption (MAD) was measured using a self-reported scale. Multiple linear regression models were employed to evaluate the association between dysmenorrhea, well-being, and academic performance. Directed Acyclic Graphs (DAGs) were employed to identify variables for control in regression models.

RESULTS

The mean dysmenorrhea score was 6.6 ± 2.6, with 37.9% and 41.2% expressing moderate and severe symptoms, respectively. The mean WHO-5 score was 58.7 ± 25.1, and 34.9% reported a low well-being status. The mean MAD score was 3.1 ± 3.3. 26% reported missing school due to dysmenorrhea, 36% said dysmenorrhea impacted their ability to concentrate, and 39% were unable to study for tests, and complete homework. The first regression analysis showed a reduction of 1.45 units in WHO-5 score for each unit increase in dysmenorrhea. The second regression analysis showed a non-linear increase in MAD score for increasing dysmenorrhea. For each dysmenorrhea score less than 4 (mild) there was a modest increase in MAD scores (coefficient 0.08, p-value = 0.006), and for each dysmenorrhea score above 4 there was a stronger increase in MAD scores (coefficient 0.95, p < 0.001).

CONCLUSION

Dysmenorrhea poses significant challenges to the well-being and academic performance of adolescent girls living in Palestine refugee camps. Collaborative efforts and multifaceted approaches are crucial to address dysmenorrhea effectively. This involves research, targeted interventions, culturally sensitive strategies, and fostering a supportive environment that empowers girls to thrive academically and beyond.

The prevalence of menstrual disorders and their association with psychological stress in Syrian students enrolled at health-related schools: A cross-sectional study

OBJECTIVES

Menstrual disorders are among the most prevalent health issues among young female students studying in health science faculties. This study aimed to provide insights into the menstrual patterns among medical faculty students and determine whether stress can be a risk factor for its various disorders.

METHODS

This cross-sectional study was conducted in the Faculties of Medicine, Dentistry, and Pharmacy at the Syrian Private University, Damascus, Syria, between October and November 2022. A total of 980 female students anonymously completed the identification of menstrual problems and the perceived stress scale (PSS) questionnaire. The data were analyzed using SPSS-25.

RESULTS

The mean age of students was 21.52 ± 2.06 years. The most common menstrual disorders in this study were dysmenorrhea (88%), and premenstrual syndrome (87%). A total of 82% had mild to moderate stress, 10% had high stress, and 8% had low stress. Moderate to high perceived stress was associated with an increased risk of PMS (OR = 1.79, P = 0.0037).

CONCLUSION

These findings stress the importance of universities, especially health science faculties, establishing protocols for early detection and intervention in students with stress and menstrual disorders. Implementing stress reduction education and timely counseling, along with preventive measures, is crucial for students' well-being. Further research is needed to refine interventions for this group.

Auricular Acupuncture Prior to Menstruation Can Reduce Primary Dysmenorrhea: A Randomized Controlled Trial

Objective

Primary dysmenorrhea is a common condition that impacts quality of life significantly. Auricular therapies have shown promise for treating primary dysmenorrhea, but there is a lack of evidence specifically for auricular acupuncture (AA). This study evaluated the safety and efficacy of AA for managing primary dysmenorrhea.

Materials and Methods

A randomized, double-blinded controlled trial was conducted on 90 females with primary dysmenorrhea: an AA group; n = 45) and a sham-AA (SA) group; n = 45. Specific ear acupoints (i.e., Uterus, Endocrine, Shenmen, Subcortex, Liver, and Kidney) were used for the intervention, which was 1 or 2 days prior to the expected menstruation onset. Outcomes were visual analogue scale (VAS) scores, ibuprofen needs, and adverse events (AEs).

Results

The AA group had significantly lower VAS scores, compared to the SA group at menstruation onset and for up to 12 hours (mean differences [MDs] and 95% confidence intervals [CIs]: -1.08 [-1.96, -0.21] and -1.17 [-2.16, -0.18], respectively). Both groups had reductions in pain levels, compared to the prior menstrual cycle; the AA group had a significantly greater improvement. The AA group needed fewer ibuprofen tablets (MD: -0.28; 95% CI: -0.58, 0.00]). AEs were mild pain and irritation at insertion sites, all resolved spontaneously with no lasting effects.

Conclusions

AA is safe. It may be effective for managing primary dysmenorrhea. Further studies are warranted on AA's effectiveness in diverse populations and extended times.

The Association of Reproductive Hormones During the Menstrual Period with Primary Dysmenorrhea

Objective

This study aimed to investigate the association of reproductive hormones with primary dysmenorrhea in Chinese women.

Methods

A case-control study was conducted and patients with primary dysmenorrhea and non-dysmenorrhea participants were recruited. Oxytocin, PGF2α, vasopressin, estriol and estradiol were respectively measured in plasma collected three to five days after menstruation. Restricted cubic spline and multiple logistic regression models were adopted to analyze the association between hormones and primary dysmenorrhea.

Results

There were 604 participants enrolled in our study including 300 patients with primary dysmenorrhea. After adjustment for the potential confounders, oxytocin levels (Q3: OR (95% CI) = 0.50 (0.27~0.95) (p=0.035); Q4: 0.34 (0.17~0.66) (p=0.001)) and PGF2α levels (Q3: 0.45 (0.24~0.87) (p=0.017); Q4: 0.43 (0.22~0.84) (p=0.013)) were respectively associated with an decreased risk of primary dysmenorrhea, but estradiol (Q2: 2.18 (1.13~4.19) (p=0.020); Q3: 2.17 (1.12~4.19) (p=0.022)) and vasopressin (Q3: 2.88 (1.48~5.63) (p=0.002); Q4: 3.20 (1.65~6.22) (p<0.001)) with an increased risk of primary dysmenorrhea, respectively. Among patients with primary dysmenorrhea, the higher estriol level was associated with higher frequent dysmenorrhea (Q2: 3.12 (1.32~7.34) (p=0.009); Q3: 4.97 (2.08~11.85) (p<0.001)) and always dysmenorrhea (Q2: 2.51 (1.03~6.11) (p=0.041); Q3: 3.10 (1.25~7.73) (p=0.015)). Similarly, high estriol levels were associated with the higher degree of pain significantly only when hormone levels were at a high level (Q3: 2.06 (1.03~4.18) (p=0.043)).

Conclusion

Higher serum vasopressin and estradiol concentrations as well as lower oxytocin and PGF2α levels were associated with higher risk of primary dysmenorrhea. Estrogen showed a reverse U-shape association on the frequency and degree of pain among patients with primary dysmenorrhea.

The Changes in Menstrual and Menstrual-Related Symptoms among Japanese Female University Students: A Prospective Cohort Study from Three Months to Nine Months after Admission

Menstrual and menstrual-related symptoms can significantly impact an individual's physical and psychological health. Understanding how these symptoms evolve over time is crucial to provide appropriate support and healthcare services to young women. This study aimed to investigate changes in menstrual and menstrual-related symptoms among first-year female university students. A prospective longitudinal design was used to compare the symptom profiles between two time points (three and nine months after admission). Out of 100 female university students, 30 responses were analyzed. Data on menstrual and menstrual-related symptoms were collected using standardized questionnaires focusing on menstrual status and the Menstrual Distress Questionnaire (MDQ); no notable changes occurred between the time points. Approximately half reported having irregular menstruation during the three time periods. Among the sub-scales, premenstrual "impaired concentration" showed a tendency to be lower, whereas menstrual "water retention" tended to be higher in timepoint 2 compared to timepoint 1. "Distractible" was found to be significantly lower in timepoint 2 compared to timepoint 1. There was a significant association between a sleep duration of <7 h and worsened MDQ scores. These findings may underscore the importance of providing comprehensive lifestyle and menstrual education to new university students, along with access to appropriate medical care.

Prevalence, Management, and Impact of Dysmenorrhea on the Lives of Nurse and Midwife Trainees in Northern Ghana

Background

Dysmenorrhea is the most common gynecological problem affecting the majority of female students in the nursing profession today. They often experience severe pain that is not only incapacitating but also has a significant impact on their day-to-day college life, academic, and clinical performance.

Aim

This study was conducted to assess the prevalence, management, and impact of dysmenorrhea on the lives of nurse and midwife trainees in northern Ghana.

Methods

A descriptive cross-sectional design with a quantitative approach to data collection was employed to collect data from nurse and midwife trainees in three colleges of nursing and/or midwifery in the northern region of Ghana. A proportionate stratified random sampling technique was used to recruit 303 respondents for the study. After gaining permission from various institutions, data were collected by using a structured questionnaire from 13th September to 28th October, 2022. Stata (special edition) for Windows version 17.0 was used for the statistical analyses.

Results

The study revealed a high prevalence of dysmenorrhea among female nursing students (66.7% and 95% CI: 0.611-0.720). More than half of the respondents (67.3%) experienced loss of appetite for food. The most common site of most intense pain was the pelvis and lower abdomen (98.0%). A greater proportion of students (65.8%) used antispastic drugs to reduce pain. The respondents' concentration in the classroom was greatly affected (77.2%) as well as normal physical activities (58.4%). A multivariable logistic regression analysis revealed that the odds of dysmenorrhea are 2.67 times higher when the duration of menstruation is 4-5 days (AOR = 1.82, 95% CI = 1.13-6.28, and p = 0.024) than a duration of 1-3 days. Having urinary tract infections was associated with 3.56 times higher odds of dysmenorrhea (AOR = 3.56, 95% CI = 0.98-12.86, and p = 0.053). Again, the odds of dysmenorrhea were also four times higher among respondents with a family history of the same condition (AOR = 4.05, 95% CI = 2.16-7.61, and p = 0.001).

Conclusion

The current study revealed a high prevalence of dysmenorrhea among nurse and midwife trainees in the northern part of Ghana. The majority of the respondent experienced loss of appetite and intense pain in the pelvis and lower abdomen, and their concentration during lectures was also significantly affected. The most predominant nonpharmacological method used for reducing the pain was sleep and the application of warm objects on the abdomen.

Desynchronization between Food Intake and Light Stimulations Induces Uterine Clock Quiescence in Female Mice

BACKGROUND

Dysmenorrhea is associated with breakfast skipping in young women, suggesting that fasting in the early active phase disrupts uterine functions.

OBJECTIVES

To investigate the possible involvement of the uterine clock system in fasting-induced uterine dysfunction, we examined core clock gene expressions in the uterus using a 28-h interval-fed mouse model.

METHODS

Young female mice (8 wk of age) were divided into 3 groups: group I (ad libitum feeding), group II (time-restricted feeding, initial 4 h of the active period every day), and group III (time-restricted feeding for 8 h with a 28-h cycle). Groups II and III have the same fasting interval of 20 h. After analyzing feeding and wheel running behaviors during 2 wk of dietary restriction, mice were sacrificed at 4-h intervals, and the expression profiles of clock genes in the uterus and liver were examined by qPCR.

RESULTS

The mice in group I took food mainly during the dark phase and those in group II during the initial 4 h of the dark phase, whereas those in group III delayed feeding time by 4 h per cycle. In all groups, spontaneous wheel running was observed during the dark phase. There was no difference in the quantity of feeding and the amount of running exercise among the 3 groups during the second week. The mRNA expressions of peripheral clock genes, Bmal1, Clock, Per1, Per2, Cry1, Nr1d1, and Dbp and a clock-controlled gene, Fabp1, in the uterus showed rhythmic oscillations with normal sequential expression cascade in groups I and II, whereas their expressions decreased and circadian cycles disappeared in group III. In contrast, liver core clock genes in group III showed clear circadian cycles.

CONCLUSIONS

Fluctuations in the timing of the first food intake impair the uterine clock oscillator system to reduce clock gene expressions and abolish their circadian rhythms.

The importance of local language in healthcare: naming and defining dysmenorrhea

INTRODUCTION

Using local language improves the quality of healthcare and patient safety but little has been done to understand and use local language in naming and defining conditions such as dysmenorrhea. Many indigenous African women value their language especially when communicating about women's health.

METHOD

In this exploratory study, we wanted to understand the local language used to construct and conceptualize dysmenorrhea and highlight the importance of local language when healthcare practitioners engage with women experiencing dysmenorrhea guided by Africana Womanism Theory. Data were collected from 15 Black indigenous women using a Lekgotla discussion group and in-depth interviews. Data were thematically analyzed.

RESULTS

Participants described how local language is important in naming and seeking healthcare. Drawing from their descriptions three themes emerged: (1) Self-naming and self-defining dysmenorrhea using a local language; (2) Types of local words, phrases, and terms used to name and define dysmenorrhea; (3) The importance of self-naming and self-defining dysmenorrhea in a local language.

CONCLUSIONS

Communication between healthcare seekers and healthcare providers is at the heart of effective healthcare provision. Poor communication due to language barriers contributes to misunderstanding, misdiagnoses, poor or incomplete patient assessment, and delayed treatment. Therefore, communicating healthcare issues in a local language would promote culturally sensitive care.

Prevalence of Primary Dysmenorrhoea and Its Impact on Academic Performance among Croatian Students during the COVID-19 Pandemic

Background

Dysmenorrhoea is one of the most common gynaecological problems. Therefore, it is important to investigate its impact during the COVID-19 pandemic which has a great impact on the lives of menstruating people all over the world.

Aim

To determine the prevalence and impact of primary dysmenorrhoea on academic performance among students during the pandemic.

Materials and Methods

This cross-sectional study was conducted in April 2021. All data were collected by an anonymous self-assessed web-based questionnaire. Due to voluntary participation in the study, 1210 responses were received, but 956 were left for analysis after exclusion criteria were applied. Descriptive quantitative analysis was performed and Kendall rank correlation coefficient was used.

Results

The prevalence of primary dysmenorrhoea was 90.1%. Menstrual pain was mild in 7.4% of cases, moderate in 28.8%, and severe in 63.8%. The study found that primary dysmenorrhoea has a great perceived impact on all included aspects of academic performance. Most affected were concentration in class in 810 (94.1%) and doing homework and learning in 809 (94.0%) female students. There is also a correlation between menstrual pain intensity and its impact on academic performance (p < 0.001).

Conclusions

Our study found that the prevalence of primary dysmenorrhoea among students at the University of Zagreb is high. Painful menstruation greatly impacts academic performance and therefore it is important to do more research on this topic.

Association between frequency of breakfast intake before and during pregnancy and infant birth weight: the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study

BACKGROUND

Low birth weight is associated with an increased risk of developing chronic diseases in adulthood, with a particularly high incidence in Japan among developed countries. Maternal undernutrition is a risk factor for low birth weight, but the association between the timing of food intake and infant birth weight has not been investigated. This study aimed to examine the association between breakfast intake frequency among Japanese pregnant women and infant birth weight.

METHODS

Of all pregnant women who participated in the Tohoku Medical Megabank Project Three Generation Cohort Study, 16,820 who answered the required questions were included in the analysis. The frequency of breakfast intake from pre- to early pregnancy and from early to mid-pregnancy was classified into four groups: every day and 5-6, 3-4, and 0-2 times/week. Multivariate linear regression models were constructed to examine the association between breakfast intake frequency among pregnant women and infant birth weight.

RESULTS

The percentage of pregnant women who consumed breakfast daily was 74% in the pre- to early pregnancy period and 79% in the early to mid-pregnancy period. The average infant birth weight was 3,071 g. Compared to women who had breakfast daily from pre- to early pregnancy, those who had breakfast 0-2 times/week had lower infant birth weight (β = -38.2, 95% confidence interval [CI]: -56.5, -20.0). Similarly, compared to women who had breakfast daily from early to mid-pregnancy, those who had breakfast 0-2 times/week had lower infant birth weight (β = -41.5, 95% CI: -63.3, -19.6).

CONCLUSIONS

Less frequent breakfast intake before and mid-pregnancy was associated with lower infant birth weight.

Menstrual characteristics and dysmenorrhea among Palestinian adolescent refugee camp dwellers in the West Bank and Jordan: a cross-sectional study

BACKGROUND

Women and girls experience menstruation throughout their reproductive years. Normal adolescent menstrual cycles gauge current and future reproductive health. Dysmenorrhea (painful menstruation) is the most prevalent menstrual disturbance in adolescents that can be debilitating. This study examines the menstrual characteristics of adolescent girls living in Palestinian refugee camps in the West Bank of the Israeli-occupied Palestinian territory and Jordan, including estimates of dysmenorrhea levels and associated factors.

METHODS

A household survey of 15 to 18-year-old adolescent girls was conducted. Trained field workers collected data on general menstrual characteristics and dysmenorrhea level using Working ability, Location, Intensity, Days of pain Dysmenorrhea scale (WaLIDD), in addition to demographic, socio-economic, and health characteristics. The link between dysmenorrhea and other participant characteristics was assessed using a multiple linear regression model. Additionally, data on how adolescent girls cope with their menstrual pain was collected.

RESULTS

2737 girls participated in the study. Mean age was 16.8 ± 1.1 years. Mean age-at-menarche was 13.1 ± 1.2; mean bleeding duration was 5.3 ± 1.5 days, and mean cycle length was 28.1 ± 6.2 days. Around 6% of participating girls reported heavy menstrual bleeding. High dysmenorrhea levels were reported (96%), with 41% reporting severe symptoms. Higher dysmenorrhea levels were associated with older age, earlier age-at-menarche, longer bleeding durations, heavier menstrual flow, skipping breakfast regularly, and limited physical activity patterns. Eighty nine percent used non-pharmacological approaches to ease menstrual pain and 25% used medications.

CONCLUSION

The study indicates regular menstrual patterns in terms of length, duration, and intensity of bleeding and a slightly higher age-at-menarche than the global average. However, an alarmingly high prevalence of dysmenorrhea among participants was found that tends to vary with different population characteristics, some of which are modifiable and can be targeted for better menstrual health.This research emphasizes the need for integrated efforts to assist adolescents with menstrual challenges such as dysmenorrhea and irregular periods to achieve informed recommendations and effective actions.

Menstrual health and hygiene among young Palestinian female university students in the West Bank: a cross-sectional study

OBJECTIVE

We investigated some aspects of menstrual health and hygiene among young female students at Birzeit University in the West Bank of the occupied Palestinian territory.

DESIGN

Cross-sectional study in a large central university.

PARTICIPANTS

Out of a total of 8473 eligible female students, a calculated sample size of 400 students aged between 16 and 27 years was obtained.SettingLarge central university, West Bank, occupied Palestinian territory (oPt).

MEASURES

An anonymous structured international research instrument consisting of 39 questions based on the Menstrual Health Questionnaire, in addition to few questions relevant to the context, was administered.

RESULTS

30.5% of participants were not informed about menstruation before menarche, and 65.3% reported that they were not ready when they got their first period. The highest reported source of information regarding menstruation was family (74.1%), followed by school (69.3%). About 66% of respondents reported that they need more information on various topics of menstruation. The most common type of menstrual hygiene products used were single-use pads (86%), followed by toilet paper (13%), nappies (10%) and reusable cloths (6%). Of the total 400 students, 14.5% reported that menstrual hygiene products are expensive, and 15.3% reported that they always/sometimes had to use menstrual products that they do not like because they are cheaper. Most (71.9%) of the respondents reported that they used menstrual products for longer time than recommended due to inadequate washing facilities at the university campus.

CONCLUSIONS

The findings provide useful evidence on the lack and the need for menstrual-related information for female university students, inadequate infrastructure to help them manage their menstruation with dignity and pointed to some menstrual poverty in accessing menstrual products. A national intervention programme is needed to increase awareness regarding menstrual health and hygiene among women in local communities and female teachers in schools and universities to enable them to disseminate information to and meet the practical needs of girls at home, at school and at the university.

The Circadian Clock, Nutritional Signals and Reproduction: A Close Relationship

The circadian rhythm, which is necessary for reproduction, is controlled by clock genes. In the mouse uterus, the oscillation of the circadian clock gene has been observed. The transcription of the core clock gene period (Per) and cryptochrome (Cry) is activated by the heterodimer of the transcription factor circadian locomotor output cycles kaput (Clock) and brain and muscle Arnt-like protein-1 (Bmal1). By binding to E-box sequences in the promoters of Per1/2 and Cry1/2 genes, the CLOCK-BMAL1 heterodimer promotes the transcription of these genes. Per1/2 and Cry1/2 form a complex with the Clock/Bmal1 heterodimer and inactivate its transcriptional activities. Endometrial BMAL1 expression levels are lower in human recurrent-miscarriage sufferers. Additionally, it was shown that the presence of BMAL1-depleted decidual cells prevents trophoblast invasion, highlighting the importance of the endometrial clock throughout pregnancy. It is widely known that hormone synthesis is disturbed and sterility develops in Bmal1-deficient mice. Recently, we discovered that animals with uterus-specific Bmal1 loss also had poor placental development, and these mice also had intrauterine fetal death. Furthermore, it was shown that time-restricted feeding controlled the uterine clock's circadian rhythm. The uterine clock system may be a possibility for pregnancy complications, according to these results. We summarize the most recent research on the close connection between the circadian clock and reproduction in this review.

Determining the Effect of COVID-19 on the Menstrual Cycle Among Women of Reproductive Age Group in the Jazan Region: A Cross-Sectional Study

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic has gravely affected the world in various ways. COVID-19 is a major health crisis, with long-term physical and mental health consequences. Many women reported menstrual irregularities during and after the pandemic. The study aimed to assess the effects of COVID-19 on menstrual cycles in females of reproductive age in the Jazan region.

METHODOLOGY

A descriptive cross-sectional research design was utilized to conduct the study in Jazan, Saudi Arabia. A structured questionnaire was used to collect data from 346 women aged 18-44 years who had normal menstrual cycles for more than a year before the outbreak and had a history of COVID-19 infection.

RESULT

The questionnaire was completed by 346 women. Only 144 (41.6%) of the study's respondents were aged 25-34 years. Of the respondents, 283 (81.8%) were university students, and 219 (63.3%) were married. The majority of women (337, 97.4%) were vaccinated against COVID-19. A total of 301 (87.0%) were healthy. Before being infected with COVID-19, 19.70% of the responders had irregular periods, which increased to 59.50% during infection and 33.20% after getting better. There was a relationship between the regularity of menstrual periods during COVID-19 infection and the duration of menstrual periods after COVID-19 (p = 0.035); the frequency of menstrual periods before (p = 0.001), during (p = 0.009), and after (p = 0.001) COVID-19; menstrual period regularity before (p = 0.001) and after (p = 0.001) COVID-19 infection; and pain severity level during (p = 0.001) and after (p = 0.004) COVID-19 infection. Regarding the perception of the impact of COVID-19 on menstrual changes, there was an association between COVID-19 infection and variation in days during two consecutive menstrual cycles (p = 0.001), changes in the duration of menstrual cycles (p = 0.022), delayed or absent menstruation (p = 0.019), and menstruation stopping (p = 0.023).

CONCLUSION

The research demonstrated the COVID-19 pandemic is an international health problem that affects women, leading to changes in regularity, duration, frequency, and severity of pain. These changes may have a long-term impact on women's reproductive health.

Skipping breakfast during pregnancy and hypertensive disorders of pregnancy in Japanese women: the Tohoku medical megabank project birth and three-generation cohort study

BACKGROUND

Hypertensive disorders of pregnancy (HDP) adversely affect the prognosis of mother and child, and the prognosis depends on the subtype of HDP. Skipping breakfast may be associated with increased blood pressure due to disruption of the circadian clock, but the association with the development of HDP has not been studied. The purpose of this study was to examine the association between skipping breakfast and the development of HDP and HDP subtypes in Japanese pregnant women.

METHODS

Of the pregnant women who participated in the Tohoku Medical Megabank Project Three-Generation Cohort Study, 18,839 who answered the required questions were included in the analysis. This study had a cross-sectional design. The breakfast intake frequency from pre-pregnancy to early pregnancy was classified into four groups: daily, 5-6 times per week, 3-4 times per week, and 0-2 times per week. HDP was classified into gestational hypertension (GH), chronic hypertension (CH), preeclampsia (PE), and severe preeclampsia (SuPE). Multiple logistic regression analysis and multinomial logistic analysis were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for breakfast intake frequency and development of HDP or HDP subtypes. We performed a stratified analysis based on energy intake.

RESULTS

Of the participants, 74.3% consumed breakfast daily, and 11.1% developed HDP. Women who consumed breakfast 0-2 times per week had a higher risk of HDP (OR: 1.33, 95% CI: 1.14-1.56), CH (OR: 1.63, 95% CI: 1.21-2.19), and PE (OR: 1.68, 95% CI: 1.27-2.21) than those who consumed breakfast daily. No association was found between skipping breakfast and the risk of developing GH (OR: 1.26, 95% CI: 0.99-1.61) and SuPE (OR: 0.91, 95% CI: 0.55-1.49). Stratified analysis showed that the risk of developing HDP due to skipping breakfast was highest in the group with the highest daily energy intake.

CONCLUSIONS

Skipping breakfast during pre-to early pregnancy is associated with the development of HDP. Further longitudinal studies are required to clarify the causal association between skipping breakfast and HDP.

Skipping the first active meal appears to adversely alter reproductive function in female than male rats

There is a growing consciousness about chrono-nutrition and its physiological functions. The human feeding pattern establishes three meals a day, meal timing however may not be adhered to. Previous studies have reported ovarian dysfunctions in breakfast skipping among females. In this study, the investigation was carried out on the effects of breakfast skipping on reproductive functions in the male rat and comparison, to the female rat. Eight-week-old animals (10 rats per group) were used to mimic post-adolescence. Rats are active at night thus the meal model was divided as follows. Female rats who had all three meals (Control_F), Female rats who had a no-first-active meal (NFAM_F), Male rats who had all three meals (Control_M), and Male rats who had a no-first-active meal (NFAM_M). All animals were fed the same amount of food every day. After the expiration of the four weeks experiment, serum testosterone, estrogen, Luteinising Hormone (LH) Follicle Stimulating Hormone (FSH), and prolactin (PRL) were quantified using ELISA. Sperm was also analyzed. There was a significant increase (p < 0.05) in the testosterone level and sperm count in the NFAM_M compared to the Control_M while the estrogen level was significantly reduced in the NFAM_F compared to the Control_F. LH, FSH, and PRL levels were significantly reduced in the NFAM_F compared to the NFAM_M. These findings further confirm that post-adolescent females are prone to breakfast skipping. The increase in testosterone levels and sperm count in the males establish that breakfast skipping might not interfere with the reproductive physiology in males as it does in females.

The potential impact of COVID-19 on women's reproductive and mental health: a questionnaire study

The pandemic has transformed the social and economic certainties of people's lives imposing stay-at-home necessities which began in mid-March 2020. This cross-sectional observational study was performed to study the impact of COVID-19 on the reproductive and mental health of women before and after the pandemic. A digital survey form of 50 questions was developed using the Google platform andshared over 4 weeks in August 2021. Paired t-test was used to compare the variables before and after the COVID-19. Of the 450 respondents, 443(98.44%) completed the questionnaire. There was a significant difference in the average duration of menstruation and the proportion of women with a cycle length of 35-45 days increased from 5 to 8% of women after the pandemic. Painful periods (28.5 to 59.5%, p = .002) and weight increased (39.2%, p < .001) after the pandemic. Stress also increased after the pandemic (p < .001). The pandemic has significantly impacted the reproductive and mental health of women. The long-term health significances of this are yet to be determined.Impact StatementWhat is already known on this subject? The pandemic has transformed the social and economic certainties of people's lives, mainly women. Women's health significantly mental health is affected by the lack of adequate domestic and emotional support which may further consequences like the risk of anxiety and depression.What do the results of this study add? Our study shows the effect of COVID-19 on women's reproductive and mental health before and after the pandemic. Inadvertent forfeits women's health and well-being and instabilities in reproductive function as raised pressure causes irregularities in the menstrual cycle.What are the implications of these findings for clinical practice and/or further research? Women have suffered from significant mental and reproductive problems during the first and second waves of the COVID-19 pandemic. But, the long-term effects of these are not unknown. Upcoming work should comprise study throughout the pandemic and the long-term impact on women's health.

Menstrual cycle irregularity during examination among female medical students at King Abdulaziz University, Jeddah, Saudi Arabia

Background

Menstrual irregularity is defined as any differences in the frequency, irregularity of onset, duration of flow, or volume of blood from the regular menstrual cycle. It is an important medical issue that many medical students suffer from. The study aimed to determine the menstrual cycle abnormalities women experienced during exams and to investigate the most common types of irregularities among female medical students at King Abdulaziz University in Jeddah, Saudi Arabia.

Methods

A cross-sectional study was conducted among female medical students between September and October 2021 at King Abdulaziz University in Jeddah, Saudi Arabia. For this study, the estimated sample size (n = 450) was derived from the online Raosoft sample size calculator. Thus, 450 female medical students from second to sixth year were selected through stratified random sampling. A validated online questionnaire collected data about demographics, menstrual irregularities during exams, type of irregularities, menstrual history, family history of menstrual irregularities, premenstrual symptoms, medication use, medical and family consultations, and absenteeism. The chi-squared test (χ2) was used to analyze the associations between variables.

Results

A total of 48.2% of participants had menstrual irregularities during exams. The most common irregularity was dysmenorrhea (70.9%), followed by a lengthened cycle (45.6%), and heavy bleeding (41.9%). A total of 93% of medical students suffered from premenstrual symptoms and 60.4% used medication such as herbal medication and home remedies to relieve menstrual irregularities, and 12.1% of the students missed classes due to menstrual irregularities. A non-significant relationship was found between menstrual irregularities during exams and students’ demographics, academic year, and age at menarche, while oligomenorrhea, a heavier than normal bleed, a longer than normal cycle, and missing classes due to menstrual irregularities were significantly higher among single students as opposed to married students.

Conclusion

The results showed that female medical students have a significant frequency of menstruation abnormalities during exams period. Colleges should raise awareness among medical students about coping with examination stress and seeking medical care for menstrual abnormalities.

Uterine Deletion of Bmal1 Impairs Placental Vascularization and Induces Intrauterine Fetal Death in Mice

Recently, it was demonstrated that the expression of BMAL1 was decreased in the endometrium of women suffering from recurrent spontaneous abortion. To investigate the pathological roles of uterine clock genes during pregnancy, we produced conditional deletion of uterine Bmal1 (cKO) mice and found that cKO mice could receive embryo implantation but not sustain pregnancy. Gene ontology analysis of microarray suggested that uterine NK (uNK) cell function was suppressed in cKO mice. Histological examination revealed the poor formation of maternal vascular spaces in the placenta. In contrast to WT mice, uNK cells in the spongiotrophoblast layer, where maternal uNK cells are directly in contact with fetal trophoblast, hardly expressed an immunosuppressive NK marker, CD161, in cKO mice. By progesterone supplementation, pregnancy could be sustained until the end of pregnancy in some cKO mice. Although this treatment did not improve the structural abnormalities of the placenta, it recruited CD161-positive NK cells into the spongiotrophoblast layer in cKO mice. These findings indicate that the uterine clock system may be critical for pregnancy maintenance after embryo implantation.

Menstrual hygiene management practices and menstrual distress among adolescent secondary school girls: a questionnaire-based study in Nigeria

Background

Menstruation is a common and normal experience during the reproductive age of adolescent females and if not well managed might expose the female to menstrual distress.

Aim & Objectives

To determine the menstrual hygiene management practices and menstrual distress among adolescent secondary school girls.

Methods & Materials

Six hundred participants randomly drawn participated in the study. A structured questionnaire which had two inventories was used to collect data. The first inventory was a self-developed Menstrual Hygiene Management Practices Questionnaire (MHMPQ) (r = 0.71) and the second one was a modified 11-item Menstrual Distress Scale (MDS) (r = 0.74). Data were analyzed using descriptive and inferential statistics.

Results

Results showed that menstrual hygiene management practices of the girls were poor and they were very highly distressed. Statistically significant differences were observed in menstrual hygiene management practices among the girls with regard to age, location of residence and occupation of mother and on menstrual distress in relation to occupation of father (p < 0.05). Significant positive relationship between menstrual hygiene management practices and menstrual distress was observed.

Conclusion

The findings accentuate the need for a caring atmosphere for menstrual sanitation both at home and in school.

Prevalence of Dysmenorrhea and Associated Factors Among Haramaya University Students, Eastern Ethiopia

Purpose

Dysmenorrhea is the most common gynecological problem among adolescents and a common cause of school absenteeism. Previously, there was no study conducted on prevalence of dysmenorrhea and associated factors among university students in Ethiopia. Therefore, the aim of this study was to assess prevalence and associated factors of dysmenorrhea among Haramaya university undergraduate regular students in Eastern Ethiopia.

Materials and Methods

An institution-based cross-sectional study design was conducted from February to March 2020. A multistage random sampling technique was applied and a total of 569 participants were included into the study. The total sample size was proportionally allocated based on the total number of students in each departments, and simple random sampling technique was employed to select participants. The data were entered to EPI‑info version 3.5.4 and then exported to Statistical Package for Social Science version 23.0 software for analysis. The associations between independent variables and outcome variable were explored using bivariate and multivariable logistic regression models. The results of these analysis were reported as odds ratios with 95% confidence intervals.

Results

The prevalence of dysmenorrhea in this study was 356 (64.7%) 95% CI [60.7%, 68.7%]. Premenstrual syndrome (AOR = 5.20:95% CI [2.82, 9.61]), early menarche (AOR = 4.67:95% CI [2.33, 9.37]), history of anxiety (AOR = 4.08:95% CI [2.31, 7.19]), taking of ≥4 glass of tea per day (AOR = 5.69:95% CI [1.49, 21.77]), usually eating fat and oil (AOR = 2.03:95% CI [1.15, 3.59]) and usual use of meat food (AOR = 3.61:95% CI [2.03, 6.39]) were positively and independently associated with the occurrence of dysmenorrhea.

Conclusion

Dysmenorrhea was a common problem among Haramaya University female students. History of anxiety, early menarche, premenstrual syndrome, tea consumption, usual use of fat and oil containing food and usual use of meat food were significantly associated to dysmenorrhea. We recommend Haramaya University to provide accessible and appropriate medical treatment and counseling service for dysmenorrhea affected students.

Female Reproductive Health Disturbance Experienced During the COVID-19 Pandemic Correlates With Mental Health Disturbance and Sleep Quality

The COVID-19 pandemic has adversely affected population mental health. Periods of psychological distress can induce menstrual dysfunction. We previously demonstrated a significant disruption in women's reproductive health during the first 6 months of the pandemic. The present study investigates longer-term reproductive and mental health disturbances. A cross-sectional online survey was completed by 1335 women of reproductive age in April 2021. It included validated standardized measures of depression (PHQ-9), anxiety (GAD-7) and sleep quality (PSQI). 581 (56%) of women reported an overall change in their menstrual cycle since the beginning of the pandemic. There was no change in median cycle length [28 days (28-30)] or days of menses [5 (4-5)], but there was a wider variability in minimum (p<0.0001) and maximum (p<0.0001) cycle length. There was a significant increase in heavy menstrual bleeding, painful periods and missed periods compared to pre-pandemic (all p<0.0001). 64% of women reported worsening pre-menstrual symptoms. Rates of severe depression, anxiety and poor sleep were more than double those from large scale representative community samples. Poor sleep quality was an independent predictor of overall change in menstrual cycle (OR=1.11, 95%CI 1.05-1.18), and missed periods (OR=1.11, 95%CI 1.03-1.19) during the pandemic. Increased anxiety was independently associated with a change from non-painful to painful periods (OR=1.06, 95%CI 1.01-1.11) and worsening of pre-menstrual symptoms (OR=1.06, 95%CI 1.01-1.07) during the pandemic. The COVID-19 pandemic continues to bear a significant impact on female reproductive health. Increased levels of psychological distress and poor sleep are associated with menstrual cycle disruption.

Primary Dysmenorrhea: Pathophysiology, Diagnosis, and Treatment Updates

Primary dysmenorrhea (PD) is a common, disregarded, underdiagnosed, and inadequately treated complaint of both young and adult females. It is characterized by painful cramps in the lower abdomen, which start shortly before or at the onset of menses and which could last for 3 days. In particular, PD negatively impacts the quality of life (QOL) of young females and is the main reason behind their absenteeism from school or work. It is suggested that increased intrauterine secretion of prostaglandins F2α and E2 are responsible for the pelvic pain associated with this disorder. Its associated symptoms are physical and/or psychological. Its physical symptoms include headache, lethargy, sleep disturbances, tender breasts, various body pains, disturbed appetite, nausea, vomiting, constipation or diarrhea, and increased urination, whereas its psychological symptoms include mood disturbances, such as anxiety, depression, and irritability. While its diagnosis is based on patients’ history, symptoms, and physical examination, its treatment aims to improve the QOL through the administration of nonsteroidal anti-inflammatory drugs, hormonal contraceptives, and/or the use of non-pharmacological aids (e.g., topical heat application and exercise). Patients must be monitored to measure their response to treatment, assess their adherence, observe potential side effects, and perform further investigations, if needed.

Abnormal interhemispheric functional connectivity in patients with primary dysmenorrhea: a resting-state functional MRI study

BACKGROUND

Neuroimaging studies have confirmed that functional connectivity (FC) disruption of pain-related brain networks may contribute to the cerebral pathophysiology of primary dysmenorrhea (PDM). However, it remains unclear whether FC of symmetrical regions of bilateral hemispheres associated with PDM is abnormal. This functional MRI study aimed to explore the changes of voxel-mirrored homotopic connectivity (VMHC) and seed-based FC in patients with PDM.

METHODS

A cohort comprising patients with PDM (n=35) and healthy controls (HCs) (n=41) underwent resting-state functional MRI scans during their menstrual phase. Interhemispheric FC was compared between the two groups using VMHC analysis. Brain areas with significant group differences in VMHC were selected as seed regions for FC analysis. Correlation analysis was also conducted to examine the relationship between abnormal connectivity of brain regions and clinical measures of pain and anxiety.

RESULTS

Compared with healthy individuals, patients with PDM showed significantly enhanced VMHC in the bilateral orbital part of the superior frontal gyrus and the bilateral middle frontal gyrus. Subsequent seed-based FC analysis showed enhanced connectivity between the aforementioned areas and pain-related brain structures. Hyperconnectivity between the left middle frontal gyrus and the right cingulate gyrus in patients was negatively correlated with an increase in the visual analogue score (VAS) for pain (r=-0.341, P<0.05).

CONCLUSIONS

Our findings indicate that ongoing dysmenorrhea is accompanied by abnormal interhemispheric functional coordination and enhanced connectivity in pain-related regions, attention networks, and the reward system. These findings may provide a novel perspective on the central mechanism of pain caused by PDM.

The Prevalence, Management and Impact of Dysmenorrhea on Medical Students' Lives-A Multicenter Study

Introduction: Dysmenorrhea is defined as the presence of painful menstruation, and it affects daily activities in different ways. The aims of this study were to assess the prevalence and management of dysmenorrhea and to determine the impact of dysmenorrhea on the quality of life of medical students. Material and methods: The study conducted was prospective, analytical and observational and was performed between 7 November 2019 and 30 January 2020 in five university centers from Romania. The data was collected using an original questionnaire regarding menstrual cycles and dysmenorrhea. The information about relationships with family or friends, couples’ relationships and university activity helped to assess the effects of dysmenorrhea on quality of life. The level of significance was set at p < 0.05. Results: The study comprised 1720 students in total. The prevalence of dysmenorrhea was 78.4%. During their menstrual period, most female students felt more agitated or nervous (72.7%), more tired (66.9%), as if they had less energy for daily activities (75.9%) and highly stressed (57.9%), with a normal diet being difficult to achieve (30.0%). University courses (49.4%), social life (34.5%), couples’ relationships (29.6%), as well as relationships with family (21.4%) and friends (15.4%) were also affected, depending on the duration and intensity of the pain. Conclusion: Dysmenorrhea has a high prevalence among medical students and could affect the quality of life of students in several ways. During their menstrual period, most female students feel as if they have less energy for daily activities and exhibit a higher level of stress. The intensity of the symptoms varies considerably and, with it, the degree of discomfort it creates. Most student use both pharmacological and non-pharmacological methods to reduce pain (75.7%). University courses, social life, couples’ relationships, as well as relationships with family and friends are affected, depending on the duration and intensity of the pain.

Differences in Menstruation-Related Symptoms of University Students Depending on Their Living Status in Japan

Mothers and family members of young female students play important roles for guiding their self-care strategies for menstruation-related symptoms; which often affect their daily life and academic life. The aim of this study is to clarify the differences in menstruation-related symptoms before and during menstruation in university students living alone and university students living with their family in Japan. We conducted a cross-sectional online survey to assess menstruation-related symptoms before and during menstruation using the menstrual distress questionnaire (MDQ). Among 135 students; the proportion of students living alone was 60.7% and the proportion of students living with their family was 39.3%. Before menstruation; the MDQ total score and the scores for negative affect and behavior change were significantly higher in students living alone than in students living with their family. During menstruation; scores for negative affect and impaired concentration were also significantly higher in students living alone. In addition; before menstruation; scores for an increase in appetite and craving for sweets were significantly higher in students living alone. Thus; living alone affected the psychological aspects of menstruation-related symptoms in young women. The results suggest that university students who live alone should be aware of the importance of talking about their menstruation problems with family members and seeking their advice

Prevalence of Dysmenorrhea and Determinants of Pain Intensity Among University-Age Women

OBJECTIVE

The study was conducted to determine the prevalence of dysmenorrhea and investigate factors associated with dysmenorrhic pain among university students in Lahore, Pakistan.

DESIGN AND SETTING

A cross-sectional study was conducted across various public and private sector universities in Lahore.

METHODS

A self-administered structured questionnaire was used to collect data from 600 randomly selected female university students.

RESULTS

The prevalence of dysmenorrhea was 91.5%. Age at menarche (odds ratio [OR] = 1.96, 95% confidence interval [CI] = 1.10-3.50) was the only significant factor associated with dysmenorrhea. The mean pain severity score among dysmenorrhic students was 5.62 ± 2.28. Most of the participants (65.8%) were experiencing moderate/severe pain. Univariate analysis showed that irregular cycle (OR [95% CI] = 1.62 [1.13-2.33]), age at menarche of ≤14 years (OR [95% CI] = 1.46 [1.05-2.04]), duration of menses of more than 5 days (OR [95% CI] = 1.42 [1.02-1.99]), stress (OR [95% CI] = 2.16 [1.54-3.03]), moderate meat/protein consumption (OR [95% CI] = 1.55 [1.08-2.21]), and medical specialization (OR [95% CI] = 1.72 [1.17-2.52]) were significantly associated with pain severity among dysmenorrhic female students. Multivariate binary logistic regression analysis revealed that medical specialization (OR [95% CI] = 1.83 [1.22-2.73]), age at menarche (OR [95% CI] = 0.603 [0.42-0.86]), regularity of menses (OR [95% CI] = 1.52 [1.04-2.22]), moderate meat/protein consumption (OR [95% CI] = 1.69 [1.16-2.45]), and stress (OR [95% CI] = 1.87 [1.32-2.66]) were independent predictors of moderate/severe dysmenorrhic pain.

CONCLUSION

The study revealed an alarmingly high prevalence of dysmenorrhea among university students. High levels of stress and early menarche were the potent determinants of moderate/severe dysmenorrhea that disturbs quality of life.

Association among dysmenorrhea and activity limitation and participation restrictions in adult women: a cross-sectional study, Brazil -2017

BACKGROUND

The present study aims to analyse if dysmenorrhea is associated with activity limitations and participation restrictions in experencied by adult women.

METHODS

This is a cross-sectional study carried out with adult women recruited from primary health services in Brazil between 2016 and 2017. Dysmenorrhea was measured via a self-report and the activity limitation and participation restrictions was assessed by the World Health Disability Assessment Schedule (WHODAS2.0). Pain and level of physical activity were assessed, respectively, by the numerical pain rating scale and International Physical Activity Questionnaire (IPAQ), short version. Associations between groups, dysmenorrhea and without dysmenorrhea (WD), were analysed by the median difference, Mann Whitney test, effect size measures and 95 % confidence interval. Statistical significance was p <0.05.

RESULTS

The prevalence of dysmenorrhea was 54 %. The pain lasted an average of three days or more (66 %). The average pain intensity, in the crisis period, was 6.1 ± 2.6, women who presented severe pain complaints were associated with considerable difficulties in their domains of mobility (p = 0.003; 2 = 0.115), participation (p = 0.030; 2 = 0.063) and total score (p = 0.012; 2 = 0.086), with a moderate effect size for all variables.

CONCLUSIONS

Severe dysmenorrhea was associated with higher scores of disabilities assessed by the WHODAS 2.0, especially in mobility, and participation domains.

Prevalence, risk factors, and management practices of primary dysmenorrhea among young females

BACKGROUND

Primary dysmenorrhea (PD) is one of the most common gynecological conditions among young females, which has a significant negative impact on health-related quality of life and productivity. Despite its high prevalence, the evidence is limited regarding the management-seeking practices and its perceived effectiveness among females with PD.

METHODS

This is a cross-sectional study conducted among 550 female students in six universities across Lebanon. The prevalence of PD, associated risk factors, and management-seeking practices were assessed using a self-administered questionnaire.

RESULTS

The prevalence of PD was 80.9%. Most of the females with PD described their menstrual pain as moderate (56%) to severe (34.6%), which significantly affected their daily activities and studying ability (P < 0.001). The major risk factors associated with PD included heavy menstrual flow (adjusted odds ratio [AOR] = 10.28), family history of PD (AOR = 2.52), history of weight loss attempt (AOR = 2.05), and medical specialization (AOR = 1.663). Only 36.9% of females with PD sought formal medical advice. Most dysmenorrheic females (76.4%) received medications for the management of PD, and remarkably none of them took hormonal contraceptives. Drugs commonly used for PD were mefenamic acid (26.2%), ibuprofen (25%), and paracetamol (11.5%), which were administered when the pain started (58.2%). All medications were significantly effective in reducing the pain score (P = 0.001), and most NSAIDs were more potent than paracetamol in managing PD (P = 0.001). However, no significant difference in adverse effects among medications was revealed. Moreover, no superiority of any individual NSAID for pain relief was established. Nevertheless, mefenamic acid was associated with the lowest risk of abdominal pain (OR: 0.03, P = 0.005) and the highest risk of flank pain (OR = 12, P = 0.02).

CONCLUSIONS

Suboptimal management of PD is practiced among university students in Lebanon. Therefore, health care providers should educate dysmenorrheic females to optimize the self-management support of PD. Furthermore, future research is required to investigate females' misconceptions about hormonal contraceptives in the management of PD, aiming to raise awareness and correct misconceptions.

A systematic review of the menstrual experiences of university students and the impacts on their education: A global perspective

Background

Higher education attainment is linked to improved health and employment outcomes but the impact of university students’ experiences of menstruation on their education is less clear. The objective of this review was to synthesise qualitative and quantitative research on university students’ menstrual experiences and educational impacts.

Methods

Eligible studies were identified through systematic searching across eight peer-reviewed databases, websites for menstrual health organisations, grey literature databases, and reference lists of included studies. Eligible studies must have reported on at least one of the antecedents or components of menstrual experience outlined in the integrated model of menstrual experience in relation to university students or reported on the impact of their menstrual experiences on their education. Study characteristics and findings were extracted, analysed and presented as a narrative synthesis. The quality of evidence was assessed with the Mixed Methods Appraisal Tool. This study is registered on PROSPERO, number CRD42020178470.

Results

Eighty-three studies were eligible for inclusion. Most studies (n = 74; 89%) were quantitative and the highest proportion of studies were conducted in lower-middle-income countries (n = 31; 37%). Self-reported dysmenorrhea, other physical and emotional menstrual-related symptoms, and menstrual stigma contributed to negative menstrual experiences among female students. Very few studies considered the menstrual experiences of non-binary and transgender menstruating students, and culturally diverse students. Dysmenorrhea contributed to university absenteeism, impaired participation and concentration, and declining academic performance. Inadequate sanitation facilities for menstrual management and challenges containing menstruation also negatively impacted education.

Conclusions

Female university students’ experiences of menstruation can negatively impact their education, highlighting the need for program and policy responses at university to improve students’ wellbeing and educational engagement. Further research on the menstrual experiences of gender diverse, migrant and international students is needed as there is insufficient evidence to date.

Pain Prevalence, Management and Interference Among University Students in South Korea: An Exploratory Cross-Sectional Study

BACKGROUND

Pain is a global health issue with a significant impact on young adults. Adverse effects caused by inappropriate pain management among university students are related to poor mental/physical health. This study aimed to explore pain prevalence, management, and interference among university students in South Korea.

METHODS

Pain intensity, painful body areas, pain management, and pain interference were measured in a convenience sample of 404 students. Descriptive statistics are reported, and a multivariable binomial logistic regression was conducted to reveal factors associated with pain interference.

RESULTS

The prevalence of acute and chronic pain was 73.5%, while 7.8% reported chronic pain (≥ 3 months). Half of university students who experienced pain reported at least four painful body areas. The average pain intensity during the past 6 months was 4.8/10. About 56% of university students who experienced pain used over-the-counter pain pills for pain management. Rest and massage were the most used non-pharmacological pain management strategies. Mood was the most reported pain interference complaint amongst university students. Greater pain interference was associated with longer pain duration, more painful body areas, and greater pain intensity.

DISCUSSION

Pain is highly prevalent among South Korean university students. Pain management programs, including education about appropriate methods of pain relief, should be developed for university students. Attention should be given to university students with widespread acute and chronic pain of high intensity to mitigate the negative impacts caused by pain interference.

Circadian Rhythms Within the Female HPG Axis: From Physiology to Etiology

Declining female fertility has become a global health concern. It results partially from an abnormal circadian clock caused by unhealthy diet and sleep habits in modern life. The circadian clock system is a hierarchical network consisting of central and peripheral clocks. It not only controls the sleep-wake and feeding-fasting cycles but also coordinates and maintains the required reproductive activities in the body. Physiologically, the reproductive processes are governed by the hypothalamic-pituitary-gonadal (HPG) axis in a time-dependent manner. The HPG axis releases hormones, generates female characteristics, and achieves fertility. Conversely, an abnormal daily rhythm caused by aberrant clock genes or abnormal environmental stimuli contributes to disorders of the female reproductive system, such as polycystic ovarian syndrome and premature ovarian insufficiency. Therefore, breaking the "time code" of the female reproductive system is crucial. In this paper, we review the interplay between circadian clocks and the female reproductive system and present its regulatory principles, moving from normal physiology regulation to disease etiology.

Predictors of pain severity among community-dwelling older adults with pain in the United States: Findings from a cross-sectional, retrospective study using 2017 Medical Expenditure Panel Survey

ABSTRACT

The purpose of this study was to determine predictors of pain severity among older United States (US) adults with pain.This cross-sectional, retrospective study utilized 2017 Medical Expenditure Panel Survey data. Eligible participants were alive for the calendar year, aged ≥50 years, and reported pain in the past 4 weeks. Hierarchical logistic regression models, adjusting for the survey design, were used to identify significant predictors of pain severity (i.e., extreme/quite a bit or moderate/little pain).An estimated 14,250,534 adults aged ≥50 with pain reported extreme/quite a bit of pain. Many variables were associated with extreme/quite a bit of pain, including: age 50 to 64 vs ≥65 years (adjusted odds ratio [AOR] = 1.49, 95% confidence interval [95% CI] = 1.22-1.82); males vs females (AOR = 0.80, 95% CI = 0.67-0.95); white race vs others (AOR = 0.75, 95% CI = 0.61-0.92); married vs other marital status (AOR = 1.31, 95% CI = 1.08-1.57); income <200% vs ≥200% federal poverty level (AOR = 1.30, 95% CI = 1.06-1.60); employed vs unemployed (AOR = 0.47, 95% CI = 0.37-0.60); limitation vs no limitation (AOR = 2.64, 95% CI = 2.09-3.33); 0, 1, 3, or 4 vs ≥5 chronic conditions (AOR ranged from 0.39 for 0 conditions to 0.77 for 4 conditions); excellent/very good or good vs fair/poor perceived physical health status (AOR ranged from 0.28 for excellent/very good to 0.40 for good); smokers vs non-smokers (AOR = 1.56, 95% CI = 1.27-1.93); exercise versus no exercise (AOR = 0.74, 95% CI = 0.62-0.88); and South vs West census region (AOR = 1.34, 95% CI = 1.04-1.74).This study found several characteristics could predict pain severity among older US adults who reported extreme/quite a bit of pain. These characteristics may guide specific areas of focus to improve patients' pain management.
