Premenstrual syndrome, a common but underrated entity: review of the clinical literature

The effects of positive psychology and physical activity on depression, anxiety, and stress among students with premenstrual syndrome: a single-blind, randomized controlled trial

BACKGROUND

Premenstrual syndrome affects many women in their reproductive years and often disrupts their social connections and work. This study aimed to compare the effects of positive psychology and physical activity on depression, anxiety, and stress among students with premenstrual syndrome.

METHODS

In this four-group parallel clinical trial with blinded data analysis, 120 eligible students who experienced premenstrual syndrome were recruited based on inclusion/exclusion criteria and randomly allocated to four groups (n = 30) including three experiment groups as positive psychology, physical activity, and positive psychology, physical activity, and control group, using a simple randomization method. All four groups completed premenstrual syndrome screening and the DASS-21 questionnaire before the intervention. Then, the positive psychology intervention group received eight sessions of 70-90 min weekly intervention, the second group received eight weeks of aerobic physical activity intervention, and the third group received positive psychology and physical activity intervention for eight weeks. The control group did not receive any interventions. The DASS-21 was completed immediately after the intervention and two months later by all four groups. In this study, the participants and investigators were not blinded; however, the analysts were. The recruitment process took place from September 2018 to March 2019. One hundred twenty participants fulfilled the study. The Data were collected and analyzed using SPSS (v18).

RESULTS

Before and immediately after the intervention, there was no statistically significant difference in depression, anxiety, and stress mean scores among the positive psychology, physical activity, positive psychology, and physical activity and control groups (p ≥ 0.05). However, two months after the intervention, a significant difference was observed between the four groups so there was a difference between the scores of the three intervention groups and the control group (p < 0.05). There was no significant difference between positive psychology, and physical activity groups. No significant adverse events or side effects were observed.

CONCLUSION

Our findings supported the use of aerobic physical activity and educational interventions based on positive psychology as non-pharmacologic interventions to reduce anxiety, depression, and stress. This research should be replicated in different settings.

Premenstrual syndrome among medical versus non-medical workers and its association with work-related quality of life

BACKGROUND

Premenstrual syndrome (PMS) is a commonly underestimated disorder that negatively impacts a woman's life. Medical workers, who live a more stressful life, may report an increased rate of PMS. Studies on the relationship between PMS and work-related quality of life for medical professionals are scarce, particularly in the Arab world. This study aimed to compare the frequency of PMS among medical versus non-medical workers at Zagazig University and to assess the association between PMS and their work-related quality of life.

METHODS

A comparative cross-sectional study was conducted. The sample population consisted of 48 medical and 48 non-medical female workers aged 18-45 years from Zagazig University. The two groups filled out a questionnaire with 3 parts: sociodemographic and occupational data, the Premenstrual Symptoms Screening Tool (PSST), and the Work-Related Quality of Life Scale (WRQL).

RESULTS

Severe PMS was reported in 45.8% of medical workers versus 20.8% of non-medical workers with a statistically significant difference between both groups (p = 0.009). Binary logistic regression showed that being a medical worker, clinical specialty, ≥ 8 years of work, ≥ 24 working hours per week, and having a non-set hourly schedule were predictors for severe PMS. PMS was found to be a statistically significant predictor of poor WRQL (p < 0.001). There was a highly significant negative correlation between the PMS score and the WRQL score (r =  - 0.302, p < 0.001).

CONCLUSION

Among medical workers, PMS is more common and more severe, and WRQL is worse and negatively correlated with PMS. We suggest further studies with larger samples to prove this association and planning for public health programs to screen for and manage PMS among medical workers in our community.

Green gram soup and barley porridge as dietary interventions for management of premenstrual syndrome in adolescent girl: A case report

Women suffer from various conditions related to menstrual cycle due to changing lifestyle, bad food habits, physical and mental stress. Pre Menstrual Syndrome (PMS) is a combination of physical and emotional symptoms that many women get one or two weeks before the start of their menstrual period. In the present study, 14 years old female patient having symptoms-lower abdominal pain, backache, breast tenderness, constipation, pimples, tiredness and unexplained anger typically in luteal phase from last 4 months, was diagnosed with mild to moderate symptoms of PMS. After proper analysis, she was suggested to consume light to digest dietary articles advised in classical texts for minimizing specific symptoms during menstruation.Thus Green gram Soup and Barley porridge was prescribed to her as lunch and dinner respectively for first three days of menstruation cycle for continuous 6 cycles. It is observed that consumption of these dietary products during the menstruation time period assisted to minimize the symptoms of PMS. This illustrates that there is a wide scope to explore the ayurvedic dietary regimen recommended during menstruation which can be used more rationally to suit menstrual disorders.

Association between physical activity and risk of premenstrual syndrome among female college students: a systematic review and 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.

Mediating effect of suicidal ideation in the association between child abuse and premenstrual syndrome among female adults

INTRODUCTION

Premenstrual symptoms encompass a range of physical, emotional, and behavioral changes that cyclically occur before menstruation. Childhood abuse has been associated with subsequent mental health challenges, yet its relationship with exacerbating premenstrual symptoms remains an understudied area. Furthermore, suicidal ideation often emerges from traumatic backgrounds such as child abuse, creating another layer of complexity. Given the rising suicide rates in Lebanon, and the concurrent increase in reported child abuse cases, this research focuses on the role of suicidal ideation as a mediator between child abuse and premenstrual syndrome.

METHODS

This cross-sectional study involved 915 female university students in Lebanon. Participants completed an online questionnaire encompassing demographic details, health lifestyle, the Premenstrual Symptoms Screening Tool (PSST), Columbia-Suicide Severity Rating Scale (C-SSRS), and Child Abuse Self Report Scale (CASRS-12). The mediation analysis was conducted using PROCESS MACRO v3.4 model 4; three pathways derived from this analysis: pathway A from the independent variable to the mediator, pathway B from the mediator to the dependent variable, Pathway C indicating the direct effect from the independent to the dependent variable.

RESULTS

The results of the mediation analysis showed that suicidal ideation mediated the association between all types of child abuse and the presence of PMS. Higher psychological (Beta = 0.21; p < 0.001), neglect (Beta = 0.02; p = 0.017), physical (Beta = 0.19; p < 0.001) and sexual (Beta = 0.20, p < 0.001) child abuse were significantly associated with higher suicidal ideation, which was significantly associated with the presence of PMS (Beta = 0.38, p = 0.001; Beta = 0.57, p < 0.001; Beta = 0.45, p < 0.001; and Beta = 0.50, p < 0.001) respectively. Finally, higher psychological (Beta = 0.17, p < 0.001), physical (Beta = 0.11, p = 0.024), but not sexual (Beta = 0.07, p = 0.198) child abuse was directly and significantly associated with the presence of PMS, whereas higher neglect (Beta = -0.06, p = 0.007) was significantly associated lower odds of having PMS.

CONCLUSION

This study highlights the mediating role of suicidal ideation in the complex association between different types of childhood abuse and premenstrual symptoms. The findings emphasize the need for trauma-informed care and tailored interventions to address the diverse impact of these factors. Recognizing the intricate relationships between child abuse, suicidal ideation, and PMS can aid healthcare providers in comprehensively addressing young women's mental and reproductive well-being. Trauma-informed care, tailored interventions and awareness of potential connections between childhood maltreatment are essential in managing these complex challenges.

Study to Determine the Prevalence of Menstrual Migraine in Reproductive-Age Women in Saudi Arabia

BACKGROUND

Migraine is a common health condition in both men and women. Premenstrual syndrome (PMS) affects many women during their menstrual cycle, with around 50-60% of women with migraine attacks experiencing menstrual headaches. Most have mild symptoms, but 5-8% suffer from moderate to severe symptoms, causing distress and functional issues. Pure menstrual migraine (PMM) occurs in about 50% of women with migraine, and it can be debilitating in terms of frequency and severity. This information is crucial for Saudi Arabian medical professionals to provide better care and support, improving the quality of life for women with PMS and menstrual migraine (MM) attacks.

OBJECTIVES

To estimate the prevalence of MM in women, to evaluate the severity and frequency of MM in women with PMS, and to identify potential risk factors aggravating MM in women with PMS in Saudi Arabia.

METHODOLOGY

A cross-sectional community-based study was conducted on reproductive-aged (18-50 years) women who had regular menstrual cycles and were diagnosed with PMS, using a self-administered questionnaire between December 2022 to May 2023 in Saudi Arabia.

RESULTS

Out of the 2130 female participants, 397 (18.6%) had migraine. Among these 397 migraine sufferers, 230 (57.9%) experienced MM, while 167 (42.1%) had non-MM. In reproductive women in general, MM occurred in 10.7% of cases, while non-MM was observed in 7.8%. There is a correlation between increasing BMI and an increased incidence of MM. About one-third of the participants experienced moderate disability due to migraine attacks, with 134 (33.8%) individuals affected. Additionally, most MM sufferers missed at least 3 days of work in the last 3 months due to their condition.

CONCLUSIONS

Migraine attacks occurring during the menstrual cycle impair the ability to engage in social, physical, household, and academic activities, often hindering the fulfillment of professional commitments. To gain a deeper understanding of menstrual and non-menstrual migraine attacks, it is essential to conduct extensive prospective studies aimed at developing effective management strategies.

Effects of the PREMEN-CALM® in the Management of the Premenstrual Syndrome: A Randomized, Double-Blind, Placebo-Controlled Pilot Study

Premenstrual syndrome is a common disorder in women of reproductive age characterized by a variety of cyclical symptoms with a great impact on their lifestyle. Available pharmacological options include both antidepressants and oral contraceptives, both of which have side effects, are expensive and not always effective. Vitamins, minerals and plant extracts have been proven to alleviate the symptomatology of the premenstrual syndrome. For this reason, the purpose of this study was to test the effectiveness of a commercial phytotherapeutic dietary supplement (PREMEN-CALM®: γ-aminobutyric acid, Rhodiola rosea L., Vitex agnus-castus, vitamin B6 and melatonin) as an alternative treatment for this condition. A randomized, double-blind, and placebo-controlled pilot study was performed. Participants (n = 42) were assessed before and after 3 months of taking the supplement (n = 21) or the placebo (n = 21). Outcome measures include antioxidant and inflammatory biomarkers, body composition, subjective sleep quality, mood state profile, quality of life, and certain characteristics of the menstrual cycle. The within-group analysis revealed a significant improvement in the total antioxidant status (1.49 ± 0.34 vs reference value 1, p = 0.002), mood state profile (p = 0.02), and affective symptoms (p = 0.01) in the women receiving the commercial phytotherapeutic dietary supplement PREMEN-CALM®. On the contrary, the between-group analysis showed no statistical differences, suggesting a plausible placebo effect. The phytotherapeutic supplement PREMEN-CALM® might be effective in treating or alleviating the symptoms of the premenstrual syndrome without adverse events. Integrative medicine approaches in the clinical practice may help improve the health of women suffering from this and other gynecological conditions.

Prevalence and correlates of premenstrual syndrome and premenstrual dysphoric disorder among women aged 18-25 in Turkey

OBJECTIVE

Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) are experienced in the luteal phase among women of reproductive age and are known to affect quality of life. This study sought to determine the prevalence and correlates of PMS and PMDD in women aged 18-25 in Turkey.

METHOD

A cross-sectional study was conducted between December 2022 and May 2023, which recruited 1125 female college students. A personal information form, the International Physical Activity Questionnaire, and the Premenstrual Syndrome Scale (PMSS) were administered. Participants who met criteria for PMS during three consecutive menstrual cycles based on the ACOG and PMSS scores were diagnosed as having PMS. Participants who met the criteria for PMDD during three consecutive menstrual cycles based on the DSM-V were diagnosed as having PMDD. Logistic regression analysis was used to determine correlates of PMS and PMDD.

FINDINGS

PMS was found in 49.2% and PMDD in 48.0% of the participants. Women having a blood group type B compared to those with blood group type A were more likely to have PMS (OR = 151.8, 95% CI = 54.5-422.6). In addition, women with PMS were less likely to be physically active based on the metabolic equivalent of task score (OR = 0.99, 95% CI= 0.98-0.99). Menstrual cycle duration was also longer among those with PMDD (OR = 1.47, 95% CI= 1.25-1.72), as was daily caffeine intake (OR = 1.01, 95% CI= 1.00-1.01). PMDD score was also found to be associated with major depressive disorder (OR = 1.06,95% = 1.05-1.07).

CONCLUSIONS

PMS and PMDD among young women in Turkey were associated with blood groups, MET scores, and other clinical characteristics that may help clinicians to identify these conditions.

Premenstrual Syndrome and Premenstrual Dysphoric Disorder's Impact on Quality of Life, and the Role of Physical Activity

Most women who menstruate experience various physical, psychological, and behavioral changes during the period between ovulation and menstruation. This study focuses on defining and diagnosing premenstrual disorders, distinguishing between premenstrual symptoms (PS), PMS, and premenstrual dysphoric disorder (PMDD). It highlights the prevalence of these conditions and their impact on women's quality of life, including social, occupational, and psychological aspects. Furthermore, the study examines the role of physical activity, particularly aerobic exercise, in managing premenstrual symptoms. Several systematic reviews are cited, suggesting that regular physical activity can effectively reduce both physical and psychological symptoms associated with PMS. In conclusion, the management of PMS involves a multifaceted approach, with exercises, dietary modifications, stress management, cognitive-behavioral therapy, and medications all playing roles. Physical activity, especially aerobic exercise, has been found to be an effective non-pharmacological therapy for alleviating PMS symptoms and improving overall well-being. However, more research is needed to determine the optimal type and dosage of exercise for individual women with PMS.

Nutritional practices to manage menstrual cycle related symptoms: a systematic review

Certain nutritional practices may reduce menstrual-related symptoms, but there is no current consensus on what foods/supplements are sufficiently evidenced to warrant promotion to reduce menstrual symptoms of naturally menstruating individuals. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Two online databases were searched for published experimental studies that investigated the effects of foods/supplements on menstrual-related symptoms in eumenorrhoeic women. Extracted data and study characteristics were tabulated and grouped on the basis of food/supplement intervention and dosage compared with UK dietary reference values (DRV) and safe upper limits. In total, twenty-eight studies and twenty-one different foods/supplement interventions were included in the review. None of the studies reported a negative effect on symptoms, twenty-three reported a positive effect and five had no effect. Eighteen different ways of measuring menstrual-related symptoms were described across the studies. The results indicate a lack of consistency in studies to confidently provide information to eumenorrheic, naturally menstruating women regarding the use of foods/supplements to reduce menstrual symptoms. Determination of menstrual-related symptoms varied along with dose and duration of food or supplements provided. These data provide some evidence for the use of vitamin D, calcium, zinc and curcumin to reduce menstrual-related symptoms of non-hormonal contraceptive users, on an individual basis; however, further investigation is required prior to implementation with a focus on robust protocols to determine and measure changes in menstrual symptoms, with interventions adhering to DRV and safe upper limits.

The role of purity and frequency in the classification of perimenstrual headache

BACKGROUND

Among all menstruation-associated headaches, only menstrual migraine has classification criteria in the International Classification of Headache Disorders 3rd edition (ICHD-3). Other menstruation-associated headaches are not generally described. The ICHD-3 classifies menstrual migraine according to headache type, timing(on days -2 to +3 of menstruation), frequency (whether headache occurs in at least two out of three menstrual cycles), and purity(whether headache occurs at other times of the menstrual cycle), and provides a reference for research on menstruation-associated headache. However, the role of frequency and purity in the classification of menstruation- associated headache is not clear Moreover, the potential risk factors for high-frequency and pure headaches have not been explored.

METHODS

The study was a secondary analysis of an epidemiological survey on menstrual migraine among nurses. Among nurses who had a headache on days -2 to +3 of menstruation, headache frequency, purity, and type were described. High-frequency vs. low-frequency and pure vs. impure headache were compared according to headache features, demographics, occupation-related factors, menstruation-related factors, and lifestyle factors.

RESULTS

Of all respondents, 254(18.3%) nurses who had headaches on days -2 to +3 of menstruation were included in the study. In the 254 nurses with perimenstrual headache, the proportions of migraine, tension type headache (TTH), high-frequency headache, and pure headache were 24.4%, 26.4%, 39.0%, and 42.1%, respectively. High-frequency and impure perimenstrual headache was more severe and similar to migraine. High-frequency headache was associated with more perimenstrual extremity swelling and generalized pain. Other variables were not significantly different between the groups.

CONCLUSIONS

Headache except for menstrual migraine accounts for a certain proportion of menstruation-associated headache and should not be ignored in research. Headache frequency and purity are related to headache type and should be equally considered in the classification of menstruation- associated headache. Perimenstrual extremity swelling and generalized pain are potential indicators of high-frequency perimenstrual headache.

Impact of nutritional diet therapy on premenstrual syndrome

Premenstrual syndrome (PMS) is one of the most common disorders faced by women of reproductive age. More than 200 symptoms of varying severity associated with PMS have been identified. Because of the broad spectrum of action of PMS and its impact on quality of life, symptom relief is the main challenge of treating PMS and premenstrual dysphoric disorder (PMDD). The review aims to analyze and identify the potential impact of dietary and nutritional therapies on PMS and, respectively, for its better management. The study was conducted by accessing Internet databases such as PubMed, ScienceDirect, and Scopus and using relevant keywords such as PMS, symptoms, dietary patterns (DPs), macro and micronutrients, and supplements. The results showed that diet is an essential modulating factor in reducing and managing PMS symptoms. But research on the actual effect of foods and nutrients on PMS is sparse, sporadic, and studied with insufficient scientific rigor. No correlations were identified between the consumption of macronutrients and PMS: protein, fat, carbohydrates, and fiber, but the effectiveness of micronutrients, especially calcium, magnesium, vitamin D, B vitamins, and herbal supplements, was demonstrated. Researchers remain unanimous that the evidence is insufficient and limited to support their use as an effective treatment. Nevertheless, the results could contribute to providing quality information to help women and girls make evidence-based decisions regarding premenstrual health and the adoption of dietary and nutritional therapies.

Effect of nitric oxide-cyclic GMP-K+ channel pathway blockers, naloxone and metformin, on the antinociception induced by the diuretic pamabrom

Pamabrom is a diuretic that is effective in treating premenstrual syndrome and primary dysmenorrhea. The aim of this study was to examine the effect of metformin and modulators of the opioid receptor-nitric oxide (NO)-cyclic guanosine monophosphate (cGMP)-K⁺ channel pathway on the local antinociception induced by pamabrom. The rat paw 1% formalin test was used to assess the effects. Rats were treated with local administration of pamabrom (200-800 µg/paw) or indomethacin (200-800 µg/paw). The antinociception of pamabrom or indomethacin was evaluated with and without the local pretreatment of the blockers. Local administration of pamabrom and indomethacin produced dose-dependent antinociception during the second phase of the test. Local pretreatment of the paws with naloxone (50 µg/paw), l-nitro-arginine methyl ester (10-100 µg/paw), or 1H-(1,2,4)-oxadiazolo[4,2-a]quinoxalin-1-one (10-100 µg/paw) reverted the antinociception induced by local pamabrom, but not of indomethacin. Similarly, the K⁺ channel blockers glibenclamide, glipizide, 4-aminopyridine, tetraethylammonium, charybdotoxin, or apamin reverted the pamabrom-induced antinociception, but not of indomethacin. Metformin significantly blocked the antinociception of pamabrom and indomethacin. Our data suggest that pamabrom could activate the opioid receptor-NO-cGMP-K⁺ channel pathway to produce its peripheral antinociception in the formalin test. Likewise, a biguanide-dependent mechanism could be activated by pamabrom and indomethacin to generate antinociception.

Depressive symptoms and menstrual distress according to the menstrual phase in nurses: the Korea Nurses' Health Study

OBJECTIVE

This study aimed to identify the level of menstrual distress among nurses during the premenstrual and menstrual phases and to investigate associations between depressive symptoms and menstrual distress.

METHODS

This was a cross-sectional study conducted using data from the Korea Nurses' Health Study. We used data from December 2018 to September 2019. A total of 6878 nurses was selected for final analysis. Data on demographic characteristics, women's health-related variables, shift work, sleep quality, depressive symptoms and menstrual distress were collected. Descriptive statistics, and hierarchical multiple regression analysis were used.

RESULTS

Depressive symptoms were significantly correlated with menstrual distress in both premenstrual and menstrual phases (premenstrual phase B = 1.60, 95% CI = 1.49-1.71; menstrual phase B = 1.65, 95% CI = 1.54-1.76) after controlling for demographic characteristics, women's health-related variables, shift work and sleep quality.

CONCLUSION

The results of this study indicate the importance of tailored care for menstrual distress based on the menstrual phase and the significance of depressive symptoms in the management of menstrual distress.

Resident intruder paradigm-induced PMDD rat model of premenstrual irritability: behavioral phenotypes, drug intervention, and biomarkers

BACKGROUND

Premenstrual dysphoric disorder (PMDD) is high in women of childbearing age with obvious premenstrual irritability. However, reliable animal models are still lacking.

MATERIALS AND METHODS

PMDD rat model of premenstrual irritability was induced by the resident-intruder paradigm (RIP). Behavioral characteristics were determined by the aggressive behavior test, elevated plus maze, open-field test, and breast width measurement. The estrous cycle in rats was artificially manipulated by bilateral ovariectomy and exogenous hormone injection to verify the model phenotype's dependence on the estrous cycle. Fluoxetine and Baixiangdan capsules were administered by gavage to determine the symptom improvement effect of PMDD irritability. Biomarkers in serum and brain were detected using ELISA, and GABRA4 was detected in the brain by RT-PCR and Western blot.

RESULTS

Rat models demonstrated similar clinical characteristics as PMDD, such as premenstrual irritability and anxiety, and the above symptoms were estrous cycle-dependent. In addition, the levels of progesterone (P) and ALLO hormones decreased in the serum, hippocampus, amygdala, and frontal lobe in the NR phase. The contents of 5-HT in the brain were significantly increased, while NE and GABA contents were considerably reduced. Moreover, mRNA and protein expression of GABRA4 levels in model rats' amygdala, hippocampus, and frontal lobe were significantly increased, while drug intervention downregulated its expression in these tissues.

CONCLUSION

Premenstrual irritability rat model of PMDD demonstrates a behavioral phenotype consistent with the clinical symptoms of PMDD and micro index. The increased levels of 5-HT, NE, and expression of GABRA4, as well as the decrease of GABA, P, and ALLO levels, may be critical biomarkers of the abnormal changes that occur during the pathogenesis of PMDD.

Academic and Social Impact of Menstrual Disturbances in Female Medical Students: A Systematic Review and Meta-Analysis

Background

The stressful academic schedule of medical students poses an obvious challenge to their daily lifestyle. Psychosomatic discomfort poses a significant risk for inaccurate self-medication for ameliorating menstrual complications and feeling better, thus directly impacting personal and academic wellbeing.

Objective

The impact of menstrual disturbances on academic life is not extensively explored. Therefore, the primary objective of this research was to probe the prevalence of menstrual disturbances and assess the academic and social impact. Finally, the authors provide an overview of pharmacological and other interventions students adopt to reduce clinical symptoms.

Methods

A database search was conducted from the year 2016 till September 2021 for the studies reporting the prevalence of menstrual disorders in all geographic locations of the world. Keywords used for searching databases included “menstrual disturbances” and “medical students,” “prevalence” OR “symptoms” of “Premenstrual syndrome” OR “Premenstrual dysphoric disorder” OR “Dysmenorrhea” in medical students. Prospero Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Meta-Analysis of Observational Studies in Epidemiology (MOOSE) protocols were followed. The protocol was registered in the International prospective register of systematic reviews (PROSPERO), the Center for Reviews and Dissemination, University of York (CRD42021277962). The quality of the methodologies used in selected studies was evaluated by a modified version of Newcastle Ottawa Scale (NOS).

Results

Initially, 1527 articles were available. After a review, 26 papers were selected for analysis. A total of 25 citations were identified for quantitative analyses, out of which 16 studies reported Pre-menstrual syndrome, 7 reported Pre-menstrual dysphoric disorder, and 13 articles reported dysmenorrhea. The pooled prevalence of Pre-menstrual syndrome was 51.30%, Pre-menstrual dysphoric disorder was 17.7%, and dysmenorrhea was 72.70%. Most common associated lifestyle factors were stress, excessive caffeine intake and lack of exercise. Painkillers, hot packs and hot beverages were amongst the common measures taken by the students to relieve their symptoms.

Conclusions

The current situation calls for action to accommodate students' needs and bridge the social gap regarding menstrual health. Proactive measures by medical educators and stakeholders are required for an inclusive, accommodating educational environment which will minimize the gender discrepancy in academic satisfaction and professional life.

Brain Activation During Processing of Depression Emotion in College Students With Premenstrual Syndrome in China: Preliminary Findings

BACKGROUND

This study aimed to investigate the neural substrates of processing depression emotion in premenstrual syndrome (PMS) and healthy subjects of college students using blood oxygenation level-dependent functional magnetic resonance imaging (BOLD-fMRI).

METHODS

During BOLD-fMRI scanning, 13 PMS patients and 15 healthy controls (HC) performed a picture visual stimulation task during luteal and follicular phases, in which participants and HC were asked to see pictures containing depression and non-depression emotions. Simultaneously, self-rating depression scales (SDS) were employed to evaluate the emotional status of participants.

RESULTS

Compared to HC, right inferior occipital gyrus, right middle occipital gyrus, right lingual gyrus, right fusiform gyrus, right inferior temporal gyrus, cerebelum_crus1_R, cerebelum_6_R, culmen, the cerebellum anterior lobe, tuber, and cerebellar tonsil of PMS patients showed enhanced activation. In contrast, sub-lobar, sub-gyral, extra-nuclear, right orbit part of superior frontal gyrus, right middle temporal gyrus, right orbit part of inferior frontal gyrus, limbic lobe, right insula, bilateral anterior and adjacent cingulate gyrus, bilateral caudate, caudate head, bilateral putamen, and left globus pallidus exhibited decreased activation.

CONCLUSION

The findings indicate that abnormal functional regulation of brain regions such as occipital lobe and cerebellum leads to abnormal changes in emotional regulation, cognitive ability, and attention distribution in PMS patients, implying significant central pathogenesis.

Evaluation of the effectiveness of a training program for coping with PMS symptoms based on IMB model in university students

Premenstrual syndrome (PMS) is a common health problem that adversely affects young women's quality of life. This paper evaluated the effectiveness of a "Training Program for Coping with PMS Symptoms based on Information-Motivation-Behavioral Skills (IMB) model" in university nursing students. This controlled intervention study was conducted between September 2017 and February 2018. No sampling was performed. The goal was to include all students who met the inclusion criteria. The sample consisted of 95 first-year nursing students from two universities divided into two groups: intervention (n = 40) and control (n = 45) (power of 84.5%, p = .05, effect size = 0.45). The intervention group received the training, followed by individual motivational counseling first and second months after the training. The control group did not participate in the training program. The intervention group had more PMS symptoms coping behaviors (recognizing premenstrual change, performing regular exercises, relaxation techniques, pursuing a healthy diet, communicating with family and friends) than their counterparts in the control group after the training program (p < .05). The intervention group had higher Premenstrual Coping Measure scores (recognizing premenstrual changes, performing self-care, avoiding harm, communicating) after training program (p < .05). Although habits are hard to break, especially at young ages, the training helped university students adopt PMS coping behaviors.
