BACKGROUND
Menstrual cycle (MC) disorders and MC-related symptoms can have debilitating effects on the health and performance of female athletes. As the participation of women in sports continues to increase, understanding the prevalence of a range of MC disorders and MC-related symptoms may guide preventive strategies to protect the health and optimise the performance of female athletes.
OBJECTIVE
To examine the prevalence of MC disorders and MC-related symptoms among female athletes who are not using hormonal contraceptives and evaluate the assessment methods used to identify MC disorders and MC-related symptoms.
METHODS
This systematic review was performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). Six databases were searched until September 2022 for all original research that reported the prevalence of MC disorders and/or MC-related symptoms in athletes not using hormonal contraceptives, which included the definitions of the MC disorders examined, and the assessment methods used. MC disorders included amenorrhoea, anovulation, dysmenorrhoea, heavy menstrual bleeding (HMB), luteal phase deficiency (LPD), oligomenorrhoea, premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD). MC-related symptoms included any affective and physical symptoms related to the MC that do not cause significant personal, interpersonal or functional impairment. The prevalence data across eligible studies were combined, and all studies were qualitatively synthesised to evaluate the assessment methods and tools used to identify MC disorders and MC-related symptoms. The methodological quality of studies was assessed using a modified Downs and Black checklist.
RESULTS
Sixty studies involving 6380 athletes were included. A wide range of prevalence was observed for all types of MC disorders, with a dearth of data on anovulation and LPD. Based on pooled data, dysmenorrhoea (32.3%; range 7.8-85.6%) was the most prevalent MC disorder. Studies reporting MC-related symptoms mostly examined the premenstrual and menstruation phases, where affective symptoms appeared more prevalent than physical symptoms. A larger proportion of athletes reported symptoms during the initial days of menstruation compared with the premenstrual phase. MC disorders and MC-related symptoms were retrospectively assessed using self-report methods in 90.0% of studies. Most studies (76.7%) in this review were graded as moderate quality.
DISCUSSION
MC disorders and MC-related symptoms are commonplace among female athletes, warranting further research examining their impact on performance and preventive/management strategies to optimise athlete health. To increase the quality of future studies, researchers should adopt standardised definitions of MC disorders and assessment methods such as a combination of calendar counting, urinary ovulation tests and a mid-luteal phase serum progesterone measurement when assessing menstrual function. Similarly, standardised diagnostic criteria should be used when examining MC disorders such as HMB, PMS and PMDD. Practically, implementing prospective cycle monitoring that includes ovulation testing, mid-luteal blood sampling (where feasible) and symptom logging throughout the MC could support athletes and practitioners to promptly identify and manage MC disorders and/or MC-related symptoms.

BACKGROUND
Clinical research and epidemiological studies have shown that many women experience physical and behavioral symptoms that begin during the luteal phase of the menstrual cycle and terminate around the onset of menses; this is called premenstrual syndrome. The reviews stated that the pooled prevalence of premenstrual syndrome was around 50 percent. However, there has been no review done on premenstrual syndrome in Africa. Therefore, the aim of this systematic review and meta-analysis was to summarize the most recent data evidence on the pooled prevalence of premenstrual syndrome and its pooled effect of associated factors in Africa.
METHOD
We used an appropriate guideline for systematic reviews and meta-analyses reports, which is the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). This review protocol was registered in PROSPERO (CRD42023414021). The publications were identified from PubMed/Medline, EMBASE, Scopus databases, and other grey searches. The included papers were the original data that reported the prevalence of premenstrual syndrome and associated factors published, in English, and papers available online from January 1, 2000, to May 30, 2023. The data was extracted in Microsoft Excel, and then it would be imported into STATA 11.0 for analysis.
RESULTS
We have included 16 studies conducted in African countries with 6530 study participants. In this meta-analysis, the pooled prevalence of premenstrual syndrome among the reproductive-age participants in Africa was 46.98 (95% CI: 28.9-65.06%). Further, in subgroup analysis, the pooled prevalence of premenstrual syndrome was 57.32% in Nigeria, 43.8% in Ethiopia, and 38.6% among university students and 66.04% among secondary school students. Among associated factors, the early age of menarche was significantly related to premenstrual syndrome.
CONCLUSION
In this review, the pooled prevalence of premenstrual syndrome in Africa was high. Among factors, the early age of menarche was a risk factor for premenstrual syndrome. This finding might help the stakeholders (mental health policy makers, administrators, and mental health professionals) to address prevention, early screening, and management of PMS among reproductive-age women, and to give attention to more vulnerable bodies.

Review
OBJECTIVE
Up to 80% of women of reproductive age are thought to experience premenstrual stress, which is characterised by physical, psychological, and behavioural changes. Yoga activity lowers harmful inflammatory secretions that provide comfort for premenstrual syndrome (PMS) sufferers.
DATA SOURCES
The following worldwide databases were searched for this systematic review: Scopus, PubMed, Cochrane Library, PEDro, and Google Scholar from inception to August 2022.
STUDY SELECTION
A PICOS framework (Population, Intervention, Comparison, Outcome, and Study Design) was used for searching. Population included those with premenstrual syndrome or premenstrual tension syndromes, intervention included yoga therapy, comparator was with control group, and outcome measures included blood pressure (SBP, DBP) and heart rate (HR).
DATA EXTRACTION AND SYNTHESIS
To evaluate the study, we employed the Methodological Index for Randomised Controlled Trials. Fixed effects meta-analysis and qualitative synthesis were conducted. A total of 14 studies out of 224 were included. The main outcome measures included in this review were SBP, DBP, HR, and Moos Menstrual Distress Questionnaire (MMDQ). For the meta-analysis, 7 studies were considered. 3 studies contributed data of SBP (mean difference (MD) = -0.30; 95% CI: -2.29 to 1.69; heterogenicity (I) = 96%; P = 0.00001) and DBP (MD = -0.25; 95% CI: -0.99 to 0.49; I = 79%; P = 0.009). HR results from 4 studies were included (MD = 0.08; 95% CI: -0.83 to 0.99; I = 89%; P = 0.00001). 3 studies contributed data of MMDQ (MD = 1.50; 95% CI: 0.91 to 2.10; I = 92%; P = 0.00001.
CONCLUSION
Yoga can help people with both medical and psychological conditions including menstrual pain, irregular periods, stress, tension, and anxiety. It has been shown to lessen women's emotional, behavioural, and physical PMS symptoms, which has enhanced their quality of life.
OBJECTIF
Jusqu'à 80 % des femmes en âge de procréer connaîtraient un syndrome prémenstruel (SPM), qui se caractérise par des changements physiques, psychologiques et comportementaux. Les activités de yoga réduisent les sécrétions inflammatoires nocives et soulagent les symptômes du syndrome prémenstruel. SOURCE DES DONNéES: Pour cette revue systématique, des recherches ont été effectuées dans les bases de données mondiales Scopus, PubMed, Cochrane Library, PEDro et Google Scholar pour la période allant de leur création au mois d'août 2022. SéLECTION DES éTUDES: Une méthode PICOS (population, intervention, comparaison, résultat et conception de l'étude) a été utilisée pour la recherche. La population à l'étude incluait les personnes souffrant du syndrome prémenstruel ou d'une tension prémenstruelle, l'intervention incluait la thérapie par le yoga, le comparateur était le groupe témoin, et les critères de jugement comprenaient la pression artérielle (systolique et diastolique) et la fréquence cardiaque. EXTRACTION DES DONNéES ET SYNTHèSE: Pour évaluer l'étude, nous avons utilisé l'indice méthodologique pour les essais cliniques randomisés. Une méta-analyse à effet fixe et une synthèse qualitative ont été réalisées. Au total, 14 des 224 études relevées ont été retenues. Les critères de jugement principaux de cette revue étaient les pressions artérielles systolique et diastolique, la fréquence cardiaque et le questionnaire de détresse menstruelle de Moos. Dans la méta-analyse, 7 études ont été prises en compte. Au total, 3 études avaient des données sur la pression systolique (différence moyenne [DM] = -0,30; IC à 95 % : -2,29 à 1,69; hétérogénéité [I] = 96 %; P = 0,00001) et la pression diastolique (DM = -0,25; IC à 95 % : -0,99 à 0,49; I = 79 %; P = 0,009). Les données de fréquence cardiaque de 4 études ont été incluses (DM = 0,08; IC à 95 % : -0,83 à 0,99; I = 89 %; P = 0,00001). Des données du questionnaire de Moos étaient disponibles pour 3 études (DM = 1,50; IC à 95 % : 0,91 à 2,10; I = 92 %; P = 0,00001).
CONCLUSION
Le yoga peut aider les personnes souffrant de troubles médicaux ou psychologiques, notamment les douleurs menstruelles, les menstruations irrégulières, le stress, les tensions et l'anxiété. Les données montrent que le yoga atténue les symptômes émotionnels, comportementaux et physiques du syndrome prémenstruel chez les femmes, ce qui améliore leur qualité de vie.

BACKGROUND
Menstrual disturbances harm women's health, and general well-being. As growing evidence highlights the relationship between sleep and menstrual disturbances, it is imperative to comprehensively examine the association between sleep and menstrual disturbance considering the multiple dimensions of sleep. This systematic review aims to identify the association between sleep and menstrual disturbances by evaluating using Buysse's sleep health framework.
METHODS
A comprehensive search of the literature was conducted in PubMed, EMBASE, psychINFO, and CINAHL to identify publications describing any types of menstrual disturbances, and their associations with sleep published between January 1, 1988 to June 2, 2022. Quality assessment was conducted using the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies. The findings were iteratively evaluated menstrual disturbances and their association with sleep using Buysse's sleep health framework. This framework understands sleep as multidimensional concept and provides a holistic framing of sleep including Satisfaction, Alertness during waking hours, Timing of sleep, Efficiency, and Sleep duration. Menstrual disturbances were grouped into three categories: premenstrual syndrome, dysmenorrhea, and abnormal menstrual cycle/heavy bleeding during periods.
RESULTS
Thirty-five studies were reviewed to examine the association between sleep and menstrual disturbances. Premenstrual syndrome and dysmenorrhea were associated with sleep disturbances in sleep health domains of Satisfaction (e.g., poor sleep quality), Alertness during waking hours (e.g., daytime sleepiness), Efficiency (e.g., difficulty initiating/maintaining sleep), and Duration (e.g., short sleep duration). Abnormal menstrual cycle and heavy bleeding during the period were related to Satisfaction, Efficiency, and Duration. There were no studies which investigated the timing of sleep.
CONCLUSIONS/IMPLICATIONS
Sleep disturbances within most dimensions of the sleep health framework negatively impact on menstrual disturbances. Future research should longitudinally examine the effects of sleep disturbances in all dimensions of sleep health with the additional objective sleep measure on menstrual disturbances. This review gives insight in that it can be recommended to provide interventions for improving sleep disturbances in women with menstrual disturbance.

Meta-Analysis Review
BACKGROUND
Premenstrual dysphoric disorder is characterised by symptoms confined to the premenstrual phase of the menstrual cycle. Confirmed diagnosis requires prospective monitoring of symptoms over two cycles, otherwise the diagnosis is provisional. We aimed to measure the point prevalence of premenstrual dysphoric disorder.
METHODS
We searched for studies of prevalence using MEDLINE, EMBASE, PsycINFO and PubMed. For each study, the total sample size and number of cases were extracted. The prevalence across studies was calculated using random effects meta-analysis with a generalised linear mixed model. Potential sources of heterogeneity were explored by meta-regression and subgroup analyses. Pre-registration was with PROSPERO (CRD42021249249).
RESULTS
44 studies with 48 independent samples met inclusion criteria, consisting of 50,659 participants. The pooled prevalence was 3.2 % (95 % confidence intervals: 1.7 %-5.9 %) for confirmed and 7.7 % (95 % confidence intervals: 5.3 %-11.0 %) for provisional diagnosis. There was high heterogeneity across all studies (I = 99 %). Sources of heterogeneity identified by meta-regression were continent of sample (p < 0.0001), type of sample (community-based, university, high school) (p = 0.007), risk of bias (p = 0.009), and method of diagnosis (p = 0.017). Restricting the analysis to community-based samples using confirmed diagnosis resulted in a prevalence of 1.6 % (95 % confidence intervals: 1.0 %-2.5 %), with low heterogeneity (I = 26 %).
LIMITATIONS
A small number of included studies used full DSM criteria in community settings.
CONCLUSIONS
The point prevalence of premenstrual dysphoric disorder using confirmed diagnosis is lower compared with provisional diagnosis. Studies relying on provisional diagnosis are likely to produce artificially high prevalence rates.

Meta-Analysis
BACKGROUND
This study aimed to analyze the relationship between physical activity and the risk of premenstrual syndrome among college students.
METHODS
Eligible studies were searched from the PubMed, Web of Science, and Embase databases. The link between physical activity and the risk of premenstrual syndrome was evaluated using odds ratio (OR) and 95% confidence interval (CI). The heterogeneity of the included studies was tested and their sources were explored by subgroup analysis. A sensitivity analysis was performed to assess the effect of a single study on the pooled results. The included studies were evaluated for publication bias. Five moderate-quality studies were included in this meta-analysis.
RESULTS
Physical activity levels were negatively associated with risk of premenstrual syndrome among college students (OR [95%CI] = 1.46 [1.09, 1.96], P = .011). The pooled results were not influenced after being stratified by the study region and whether multi-factor correction was performed or not. Publication bias was not observed in the included studies.
CONCLUSION
A high level of physical activity is dramatically associated with a reduced risk of premenstrual syndrome among female college students.

BACKGROUND
Dysmenorrhea and premenstrual syndrome (PMS) are common periodic and frequent complications in women of reproductive age that can negatively affect health and quality of life. The present study examined the effects of curcumin on the severity of dysmenorrhea and PMS symptoms.
METHODS
A systematic review and meta-analysis of randomized controlled trials was conducted by searching databases such as the Cochrane Library, EMBASE, Scopus, PubMed, and Web of Science from inception to January 2023. Article screening was performed using Endnote ver. X8 (Clarivate). Review Manager (RevMan ver. 5.3; Cochrane) was used for the quality assessment and meta-analysis. A total of 147 studies were screened, of which five were finally selected for quantitative and qualitative analyses. The studies were conducted between 2015 and 2021, and a total of 379 participants with a mean age of 23.33±5.54 years had been recruited in these studies.
RESULTS
The meta-analysis showed that curcumin consumption could significantly reduce the severity of dysmenorrhea (mean difference, -1.25; 95% confidence interval [CI], -1.52 to -0.98; three studies; I2=31%) and the overall score of PMS (standardized mean difference, -1.41; 95% CI, -1.81 to -1.02; two studies; I2=0%).
CONCLUSION
The reduction in the severity of PMS and dysmenorrhea has been attributed to curcumin's anti-inflammatory and antidepressant activities. Although the findings suggest that curcumin may be an effective treatment for reducing the severity of PMS and dysmenorrhea, further research with a larger number of participants from various socioeconomic levels and a longer duration of treatment is needed to evaluate the effective dose of curcumin.

Effect of nutritional interventions on the psychological symptoms of premenstrual syndrome in women of reproductive age: a systematic review of randomized controlled trials.
CONTEXT
Premenstrual syndrome (PMS) affects approximately 48% of women of reproductive age worldwide. It can lead to functional impairment, lower quality of life, and decreased work productivity. Despite the availability of medical treatment options, women are seeking alternative interventions because of concerns of harmful side effects and limited evidence of efficacy associated with pharmacological treatments. To date, high-quality research investigating the effects of dietary and nutrient intervention on PMS is limited.
OBJECTIVE
This systematic review investigated the effect of nutritional interventions on the psychological symptoms of PMS.
DATA SOURCES
Five electronic databases were searched for randomized controlled trials (RCTs) published in English from inception to October 2022. Trials eligible for inclusion were nutritional intervention studies involving women of reproductive age that measured PMS-associated psychological outcomes.
DATA EXTRACTION
Articles were selected using prespecified inclusion criteria. Data screening and extraction and risk-of-bias assessments were conducted by 3 independent reviewers using article screening software and the Cochrane Risk of Bias 2 tool.
DATA ANALYSIS
Thirty-two articles reporting on 31 RCTs involving 3254 participants, ranging in age from 15 to 50 years were included and narratively reviewed. Only 1 of the included studies had a low risk of bias. Treatment with vitamin B6, calcium, and zinc consistently had significant positive effects on the psychological symptoms of PMS. There was insufficient evidence to support the effects of vitamin B1, vitamin D, whole-grain carbohydrates, soy isoflavones, dietary fatty acids, magnesium, multivitamin supplementation, or PMS-specific diets.
CONCLUSIONS
There is some evidence to support the use of nutritional interventions for improving psychological symptoms of PMS. However, more research using consistent protocols, procedures to minimize risk of bias, intention-to-treat analysis, and clearer reporting is required to provide conclusive nutritional recommendations for improving PMS-related psychological outcomes.

Review
The effect of Crocus sativus on several disorders has been discussed or even confirmed, but the efficacy of this herb on the female reproductive system has not been well presented. In this regard, this systematic review comprehensively discussed the efficacy of C. sativus and its main phytochemical compounds on the female reproductive system and its disorders for the first time. In this systematic review, scientific databases, including PubMed, Web of Sciences, Google Scholar, Scopus, and Scientific Information Database, were explored profoundly. In vivo, in vitro, and human studies published until the end of July 2023, which had investigated the pharmacological properties of C. sativus, crocin, crocetin, safranal, or picrocrocin on the female reproductive system, were selected. A total of 50 studies conducted on the effect of C. sativus on the female reproductive system were acquired. These studies confirmed the efficacy of C. sativus or its main phytochemical ingredients in several aspects of the female reproductive system, including regulation of sex hormones, folliculogenesis, ovulation, and protection of the ovary and uterus against several oxidative stress. Several retrieved studies indicated that this herb also can alleviate the symptoms of patients suffering from dysmenorrhea, premenstrual syndrome, menopause, polycystic ovary disease (PCOD), and sexual dysfunction. Furthermore, it is a promising candidate for future studies or even trials regarding ovarian and cervical cancers. This review concluded that C. sativus can improve the symptoms of several female reproductive system disorders, which is particularly due to the presence of phytochemical ingredients, such as crocin, crocetin, and safranal.

BMC Complementary Medicine and Therapies Feb 2024Evening primrose oil (EPO), extracted from the seeds of Oenothera biennis, has gained attention for its therapeutic effects in various inflammatory conditions.
BACKGROUND
Evening primrose oil (EPO), extracted from the seeds of Oenothera biennis, has gained attention for its therapeutic effects in various inflammatory conditions.
METHOD
We performed a systematic search in multiple databases and defined the inclusion criteria based on the following PICOs: P: Patients with a form of inflammatory condition, I: EPO, C: Placebo or other therapeutic interventions, O: changes in inflammatory markers or patients' symptoms; S: randomized controlled trials. The quality of the RCTs was evaluated using Cochrane's RoB tool.
RESULTS
Several conditions were investigated in the literature. In rheumatoid arthritis, mixed results were observed, with some studies reporting significant improvements in symptoms while others found no significant impact. EPO showed some results in diabetes mellitus, atopic eczema, menopausal hot flashes, and mastalgia. However, it did not demonstrate effectiveness in chronic hand dermatitis, tardive dyskinesia, psoriatic arthritis, cystic fibrosis, hepatitis B, premenstrual syndrome, contact lens-associated dry eyes, acne vulgaris, breast cyst, pre-eclampsia, psoriasis, or primary Sjogren's syndrome. Some results were reported from multiple sclerosis after EPO consumption. Studies in healthy volunteers indicated no significant effect of EPO on epidermal atrophy, nevertheless, positive effects on the skin regarding hydration and barrier function were achieved.
CONCLUSION
Some evidence regarding the potential benefits of EPO in inflammatory disorders were reported however caution is due to the limitations of the current survey. Overall, contemporary literature is highly heterogeneous and fails to provide strong recommendations regarding the efficacy of EPO on inflammatory disorders. Further high-quality studies are necessitated to draw more definite conclusions and establish O. biennis oil effectiveness as an assuring treatment option in alleviating inflammatory conditions.
