Psychological factors and premenstrual syndrome: A Spanish case-control study

The role of the neuroinflammation and stressors in premenstrual syndrome/premenstrual dysphoric disorder: a review

Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) are prevalent emotional disorders in females, characterized by cyclic variations in physiological stress responses and emotional symptoms that correspond with the menstrual cycle. Despite extensive research, the underlying causes of these disorders remain elusive. This review delves into the neurobiological mechanisms connecting stress-induced neuroinflammation with PMS/PMDD. Additionally, it traces the conceptual development and historical context of PMS/PMDD. The review further evaluates clinical evidence on the association between PMS/PMDD and stress, along with findings from both clinical and animal studies that link these disorders to inflammatory processes. Additionally, the neurobiological pathways by which inflammatory responses may play a role in the pathogenesis of PMS/PMDD were elucidated, including their interactions with the hypothalamic-pituitary-ovary (HPO) axis, serotonin-kynurenine (5-HT-KYN) system, GABAergic system, brain-derived neurotrophic factor (BDNF), hypothalamic-pituitary-adrena(HPA)axis and. Future research is encouraged to further investigate the pathogenesis of PMS/PMDD through the perspective of neuroinflammatory responses.

Premenstrual Dysphoric Disorder: A Cross-Sectional Study on Prevalence and Awareness Among Medical Students

BACKGROUND

 Premenstrual dysphoric disorder (PMDD), a severe form of PMS, has been recognized recently as a mental disorder. PMDD can present with disabling physical, mental, and psychological symptoms affecting women's daily functions. Due to its overlapping nature with other disorders, the prevalence of PMDD remains unknown. This study aimed to evaluate the awareness of PMDD among medical students and to assess the prevalence of PMDD among female students.

METHODS

 This cross-sectional study included 377 medical students from King Saud bin Abdulaziz University for Health Sciences, Jeddah. PMDD awareness was assessed using a self-developed questionnaire, and prevalence among women was evaluated with the PSST. Data were analyzed using the John's Macintosh Project software, version 10.0 (JMP Statistical Discovery, LLC, Cary, NC), with chi-square, Mann-Whitney, and Kruskal's tests, considering p < 0.05 as statistically significant.

RESULTS

 Out of 377 students, there was a significant difference in recognizing PMDD as a mental disorder between 106 female students (66%) and 51 male students (27.3%). Significantly higher PMDD awareness was observed among students in the clinical years and those with medical or mental conditions. Around 40% of the students had a positive attitude toward PMDD, believing it may require medical management. Among the 150 female medical students who met the inclusion criteria for PSST assessment to screen for PMDD, 8.7% tested positive, and this was correlated with the severity of dysmenorrhea. Anxiety/tension was the most common symptom in the PMDD group, with significant impairment in social activities and home responsibilities.

CONCLUSION

 The study demonstrated a noticeable level of awareness toward PMDD among medical students, especially among women and those in the clinical years. The association between PMDD symptoms and the severity of dysmenorrhea highlights the relationship between hormonal fluctuations and PMDD manifestations. Early detection and intervention are required to improve the quality of life for women with PMDD. Further research is recommended to assess the awareness of practitioners and the general population about the diagnosis of PMDD and to explore PMDD pathophysiology.

Women with premenstrual syndrome exhibit high interoceptive accuracy, but low awareness, with parasympathetic rebound responses from stress

Premenstrual syndrome (PMS) is characterized by emotional or physical discomfort that occurs specifically during the luteal phase. However, women with PMS typically do not exhibit abnormalities in serum sex hormone levels or structural anomalies, making it challenging to identify distinct pathological findings unique to PMS. Instead, they may exhibit hypersensitivity to fluctuations in sex hormone levels within the normal range. This study involved experiments conducted in the late luteal phase. The pre-stress baseline state evaluated the effects of PMS on interoception using the Heartbeat Counting Task (HCT) and the Multidimensional Assessment of Interoceptive Awareness (MAIA), and the effects on emotional states using a questionnaire assessing subjective emotions in the late luteal phase. The results indicated that the "PMS group" scored higher on the HCT compared to the "without PMS group," while their MAIA scores were lower. Additionally, the PMS group reported experiencing more negative and stressful states. The findings suggest that women with PMS demonstrate high accuracy in but lower awareness of interoception. This mismatch between "accuracy" and "awareness" may indicate a maladaptive state regarding mental health. The stress-related analysis examined whether the effects of stress on exacerbating PMS include impacts on interoception and the autonomic nervous system (ANS). States before baseline, immediately after, and during stress recovery were evaluated. The results revealed that women in the PMS group exhibited more pronounced negative and stressful states; they showed higher scores on the HCT, with scores progressively increasing as the task was repeated. Regarding ANS indices, no main effect of group was observed, but parasympathetic activity increased during the recovery period compared to the pre-stress baseline. In the degree of changes in parasympathetic activity from the baseline to post-stress and recovery periods, a group-by-time interaction effect was observed. These findings suggest that the PMS group may experience a prolonged rebound effect during the recovery phase following induced stress. In conclusion, women with PMS exhibit a discrepancy between high interoceptive accuracy and low awareness of their sensations. This may contribute to heightened discomfort and suggest that vulnerability to stress, mediated by the parasympathetic nervous system, exacerbates factor for PMS symptoms.

Anxiety sensitivity, perceived stress, personality traits and premenstrual syndrome in young adult women healthcare workers during the COVID-19 pandemic

BackgroundPremenstrual syndrome (PMS) is a common disorder affecting women of reproductive age. The severity and persistence of PMS may cause deterioration of physical, social and psychological balance and affect relationships and performance in the workplace.ObjectiveThe majority of those working in health care services during the COVID-19 pandemic were women therefore the aim of this study was to investigate the differences and relationship between anxiety sensitivity (AS), perceived stress, personality traits with and without the presence of PMS in young adult women healthcare workers during the COVID-19 pandemic period.MethodsThis study consisted of 1008 participants. The following data were collected: PMS, AS Index-3, Perceived Stress Scale, Revised Eysenck Personality Questionnaire, sociodemographic data, and menstruation characteristics.ResultsWomen with PMS had higher AS (27.64 ± 15.55 vs. 16.51 ± 11.20) and perceived stress (23.52 ± 6.67 vs. 19.16 ± 5.24) levels than women without PMS. The mean neuroticism (4.20 ± 1.72 vs. 3.19 ± 1.81) and psychoticism (1.74 ± 1.06 vs. 1.51 ± 1.24) scores were higher and the mean extraversion score (3.87 ± 1.73 vs. 3.98 ± 1.77) was lower in women with PMS than in those without PMS. PMSS exhibited a statistically significant, moderate, positive correlation with the ASI-3 (r = .414, p < .001) and PSS (r = .487, p < .001) scores. Furthermore, PMSS exhibited a weak positive correlation with the neuroticism (r = .236, p < .001) and psychoticism (r = .219, p < .001) subscales and a moderate negative correlation with the extraversion (r = -.560, p = .015) subscale. As the PMSS score increased, the ASI, PSS, neuroticism, and psychoticism scores increased. However, the extraversion score decreasedConclusionsYoung adult women will benefit from psychotherapeutic and educational interventions to manage PMS, which will minimize the number of physical and psychological issues they experience.

Premenstrual Syndrome and the Attitudes Toward Seeking Professional Psychological Help Among College Students in Oman

Background

This study examines the relationship between premenstrual syndrome (PMS) and the attitude toward seeking professional psychological help among Omani college students.

Method

This study used a cross-sectional design with a convenience sampling approach. The date was issued between January and March 2024. A sample of 601 undergraduate female students completed the study questionnaires, including (1) a sociodemographic questionnaire, (2) the Premenstrual Syndrome Scale and (3) the attitude toward seeking professional psychological distress scale.

Results

The study included 601 eligible participants of age 18-29 years who were mostly single (83.7%) and living on campus (68.6%). PMS prevalence was high at 87.9%, with a mean score of 109.4, indicating low severity for most (62.1%). Participants generally had positive attitudes toward seeking psychological help (41.6% high willingness). A linear regression showed a positive link between PMS severity and help-seeking attitudes.

Conclusion

This study highlights a significant association between the experiences of PMS and attitudes toward seeking professional psychological help among Omani female undergraduate students. With a high prevalence of PMS reported, the findings suggest that cultural factors and support systems play crucial roles in shaping these attitudes. The positive inclination toward seeking help indicates a growing awareness of mental health issues within this demographic. Enhancing mental health services and fostering supportive environments in educational settings can further empower students to address PMS-related challenges.

The predictive role of common symptoms of premenstrual syndrome in the clinical practice of nurses: a cross-sectional study

BACKGROUND

Female nurses with high occupational stress are one of the groups at risk of premenstrual syndrome (PMS). The symptoms of this syndrome may affect the reduction of work efficiency, accuracy in doing work, concentration, and increased absenteeism of nurses and can lead to significant economic losses. This study aimed to determine the predictive role of common PMS symptoms in the clinical performance of nurses in public hospitals in Sanandaj, Iran.

METHODS

The present study was a descriptive-analytical and cross-sectional study. In this study, 318 nurses participated in the census method based on the inclusion criteria. Data collection tools were premenstrual symptom screening questionnaires and nurses' clinical performance evaluations. Data analysis was done with Spearman's correlation tests, simple linear regression, multiple regression, t-test, one-way variance analysis, Tukey's post hoc tests, and LSD using SPSS version 22 statistical software.

RESULTS

The average PMS score of the participants was 30.8 ± 11.45, which indicates severe PMS. Nurses' average clinical performance score was 45.78 ± 35.29, indicating an average performance. The findings showed that PMS has a significant inverse correlation with clinical performance and its components. Simple linear regression showed that PMS can predict 26.5% of nurses' clinical performance variance. Simple regression showed that with an increase of one standard deviation in the PMS score, the nurses' clinical performance score decreased by 0.517 standard deviations and vice versa. However, by controlling confounding variables, with an increase of one standard deviation in the PMS score, the clinical performance score of nurses will decrease by 0.396 standard deviations and vice versa.

CONCLUSIONS

Paying attention to reducing or controlling PMS symptoms may help improve nurses' performance. Therefore, hospital and nursing managers can improve the performance and efficiency of their workforce by identifying nurses and other employees suffering from PMS and planning and using different methods to reduce its symptoms.

Global burden and trends in female premenstrual syndrome study during 1990-2019

PURPOSE

Premenstrual syndrome (PMS) is prevalent worldwide and considered a crucial issue regarding women's health. In the present study, the Global Burden of Disease (GBD) Study 2019 dataset was utilized to assess the distributional trends in PMS burden and prevalence in regional, national, and sociodemographic index (SDI) categories.

METHODS

The analytical methods and approaches used in the 2019 GBD study were adopted to investigate the incidence rates and disability-adjusted life years (DALY) related to PMS in 204 countries or regions. Age-standardized incidence rates (ASIR), 95% uncertainty intervals (95% UI), and annual percentage changes (EAPC) were calculated from the data.

RESULTS

The global incidence and disability-adjusted life years of PMS exhibited a declining trend in the year 2019. Regions with medium-low SDI had the greatest burden of PMS, with the regions of South Asia (ASR = 7337.9 per 10,000) exhibiting the greatest Age-standardized incidence rates, while the high-income North American states presented the fastest upward trends in Age-standardized disability-adjusted life year rates. At the national level, 107 nations exhibited a decreasing trend in PMS incidence ASR, while 97 nations exhibited an increasing trend, with the United States presenting the greatest increase.

CONCLUSIONS

The present study highlighted that even though the global PMS incidence and disability-adjusted life years have decreased from the year 1990 to 2019, PMS remains a prevalent health concern for women worldwide. While addressing preventive measures and treatment, it is also important to consider the regional and national differences in PMS to develop further effective and targeted health policies.

Network structure of complex interactions of premenstrual syndrome and influencing factors in young adult women

BACKGROUND

In the transition phase from adolescence to adulthood, premenstrual syndrome (PMS) occurs more commonly, with a variety of symptoms. The occurrence of PMS may be the result of a combination of demographic, physiological, psychological and sociological factors. This study aimed to identify the central symptoms of PMS, and explored the complex influencing factors especially the one-to-one inter-relationships factors with specific symptoms.

METHOD

This is a cross-sectional study conducted in mainland China. 3458 young adult women were assessed. Using the Premenstrual Syndrome Scale (PSS) to assess the PMS, and PSS score was over 6 divided into PMS group, and vice versa. Influencing factors were assessed by a set of self-reported questionnaire. Network analysis was used to examined the interplay of PMS, whilst also considering the influencing factors of PMS.

RESULTS

In summary, 1479 participants were in PMS group. Anxiety had the highest strength centrality (1.12/1.09), shown higher centrality in the both network. Swelling of the hands or feet also shown higher strength centrality (0.89) in PMS group. PMS is associated with a higher history of dysmenorrhea, and neurotic personality. Neurotic personality - depressed mood/nervousness (0.27/0.23), history of dysmenorrhea - abdominal distension (0.21), had significantly higher weight than other edges in PMS group.

CONCLUSION

Anxiety was the most central symptom in the network, and was closely associated with other symptoms like depressed mood, which provided additional evidence for the centrality of emotional features in PMS. Moreover, the influencing factors of PMS combined demographic, physiological, psychological, and sociological factors. According to the central symptoms and factors affecting the specific PMS symptoms in young adult women, targeted intervention is helpful to prevent and alleviate PMS.

LIMITATION

Cross-sectional design cannot infer the directionality of the associations between variables. All data is self-reported with recall bias and the edge weights across the constructs of influencing factors and PMS were fairly small.

(S)-S-adenosylmethionine in the treatment of pre-menstrual disorders in adult women: A protocol for an open-label pilot study

Pre-menstrual disorders, including pre-menstrual syndrome and pre-menstrual dysphoric disorder, are highly prevalent disorders in women of reproductive age. Pre-menstrual disorders are associated with debilitating symptoms that onset in the days prior to menses. A complex interplay between hormonal fluctuations, cellular sensitivity, and psychosocial stressors likely underly the pathophysiology of pre-menstrual disorders. Current treatment options include selective serotonin reuptake inhibitors, hormonal therapies, and psychosocial support. There is growing evidence for oestrogen, progesterone, gonadotropin Releasing Hormone analogues and Complementary and Alternative Medicines in treating Pre-menstrual disorders. (S)-S-adenosylmethionine is a complementary and alternative medicine with postulated roles in the treatment of depression, with a rather rapid onset of action and minimal side effect profile. We propose a protocol for investigating the efficacy of (S)-S-adenosylmethionine in the treatment of pre-menstrual disorders. The proposed study is an open label pilot study, that will recruit thirty women between the ages of 18-45 who experience a pre-menstrual disorder. Daily and interval questionnaires will provide a quantification of symptoms across four menstrual cycles (16 weeks). During two consecutive menstrual cycles it is proposed that participants receive oral (S)-S-adenosylmethionine Complex 400 mg three times a day (total daily dose 1200 mg), during the pre-menstrual time-period (14 days prior to menses). Changes in pre-menstrual disorder symptoms between control and treatment cycles will assist in elucidating the clinical efficacy of (S)-S-adenosylmethionine. This study has the potential to support a larger double blinded, placebo controlled randomised control trial and aims to enrich the knowledge surrounding pre-menstrual disorders.

Severity of premenstrual symptoms among women with musculoskeletal pain: relation to vitamin D, calcium, and psychological symptoms

Premenstrual syndrome (PMS) has various symptoms that occur during the luteal phase of the menstrual cycle and subside after menstruation. Anxiety and depression are prevalent in women with PMS and may exacerbate the severity of PMS. Vitamin D and calcium deficiency may have a role in developing anxiety, depression, and musculoskeletal pain (MSP). The aim of this study was to evaluate selected premenstrual symptoms in relation to serum vitamin D levels, daily calcium consumption, and psychological symptoms among women with MSP. The study population consisted of 108 women with MSP and 108 healthy controls. Information about premenstrual symptoms and calcium consumption were collected. Psychological symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS). Vitamin D was determined by electrochemiluminescence immunoassay. Women with MSP had lower serum vitamin D levels, lower daily calcium consumption, higher HADS scores for anxiety and depression, and higher frequency of severe premenstrual symptoms including fatigue, headache, irritability, mood swings, anxiety, depression, and social withdrawal compared to controls (P < 0.01). Abnormal HADS scores for anxiety and depression were associated with increased severity of premenstrual symptoms (P < 0.05). Deficient vitamin D and calcium consumption were associated with abnormal HADS scores for anxiety and depression (P < 0.05) and with increased severity of premenstrual headache, irritability, anxiety, and depression (P < 0.05). Low calcium consumption was associated with increased severity of premenstrual irritability, anxiety, depression, and social withdrawal (P < 0.05). The results suggest that vitamin D deficiency, low calcium consumption, psychological symptoms, and MSP could be interrelated and implicated in the etiology severe premenstrual symptoms. Further studies are necessary to assess whether vitamin D and calcium supplements can relieve MSP and premenstrual symptoms.

Blunted Cortisol Response to Acute Psychosocial Stress in Women With Premenstrual Dysphoric Disorder

BACKGROUND

Despite being considered a stress-related condition, it is not known whether the hypothalamic-pituitary-adrenal (HPA) axis is dysfunctional in response to acute psychosocial stress in premenstrual dysphoric disorder (PMDD). This is problematic because many women with PMDD report that they are not able to control their stress levels, and a blunted cortisol output has been identified in women with related psychiatric conditions, such as anxiety and depression. The present study is a part of the Premenstrual Hormonal and Affective State Evaluation (PHASE) project, and it aimed to characterize the cortisol trajectory in response to an acute psychosocial stress challenge.

METHODS

Women with PMDD and healthy controls with confirmed ovulatory cycles underwent the Trier Social Stress Test (TSST) procedure in the mid-late luteal phase of the menstrual cycle, throughout which we collected serum samples of cortisol that we analyzed using ultra-performance liquid chromatography tandem mass spectrometry.

RESULTS

The linear mixed model analysis indicated a significant time*diagnosis interaction (P = .008) such that women with PMDD displayed significantly lower serum cortisol levels at +40 through +90 minutes from the time of stress induction.

CONCLUSION

This is the first study to show that women with PMDD have a blunted cortisol response to psychosocial stress. Combined with our earlier finding showing a greater parasympathetic nervous system withdrawal on heart oscillations in PMDD during acute stress, these and other results show that the dysregulated processing of stress in PMDD may be captured using objective study measures.

[Premenstrual syndrome and premenstrual dysphoric disorder-Overview on pathophysiology, diagnostics and treatment]

Premenstrual syndrome and premenstrual dysphoric disorder become episodically manifest during the second half of the female menstrual cycle and are characterized by psychological and physical symptoms causing relevant functional and social impairments. Mood swings, depression and dysphoria are associated depressive symptoms. Therefore, affective disorders should be considered as a differential diagnosis. Of women in reproductive age 3-8% suffer from premenstrual syndrome and 2% of women are affected by premenstrual dysphoric disorder. Genetic and sociobiographical risk factors are discussed. Furthermore, genetic polymorphisms of specific hormone receptors are considered to be genetic risk factors. From a pathophysiological perspective premenstrual syndrome and premenstrual dysphoric disorder are caused by a complex interaction between cyclic changes of ovarian steroids and central neurotransmitters. An imbalance of estrogen and progesterone in the luteal phase is believed to cause the symptoms. Therefore, the first treatment approach consists of regulation of the menstrual cycle or luteal support with progesterone or synthetic progestins even if their effectiveness has not yet been proven in randomized controlled studies and meta-analyses. The administration of combined oral contraceptives is also an option. Especially treatment with selective serotonin reuptake inhibitors (SSRI) represent an evidence-based approach. In severe cases the administration of gonadotropin releasing hormone (GnRH) agonists with add back treatment can also be considered. In the field of affective disorders premenstrual syndromes represent clinically relevant differential diagnoses and comorbidities, which confront the treating physician with particular clinical challenges. Therefore, this literature review gives the readership a clinical orientation for dealing with these disorders.

Does an alternate-day modified fasting diet improve premenstrual syndrome symptoms and health-related quality of life in obese or overweight women with premenstrual syndrome? A randomized, controlled trial

Background

Premenstrual syndrome disorder (PMS) is a condition that affects health-related quality of life (HRQoL) and encompasses a variety of symptoms, including psychological, physical, and behavioral symptoms. Some evidence suggests that an increase in body mass index (BMI) can reduce both HRQoL and menstrual quality. This is because the body fat tissue can affect menstrual cycles by changing the estrogen/progesterone ratio. This study investigated the impact of two diets alternate-day modified fasting (ADMF) and daily calorie restriction (DCR) - on PMS syndrome and HRQoL.

Methods

The study was a randomized controlled, open-label trial that lasted for 8 weeks and involved 60 obese/overweight women. Participants were recruited from the Health Service Centers of Kashan University of Medical Sciences using simple random sampling. The study compared the impact of the ADMF and DCR diets on HRQoL and PMS symptoms. Patients were classified based on their BMI and age and then allocated to either the intervention (ADMF) or control (DCR) group using a random numbers table. The study measured HRQoL, PMS severity, weight, BMI, body fat mass, waist circumference, fat-free mass, and skeletal muscle mass before and after the study. The study had an almost 18% dropout rate.

Results

Significant improvements were observed in mood lability (p = 0.044) and expressed anger (p < 0.001) in relation to PMS symptoms. However, no significant differences were detected in the changes of other COPE subscales. The ADMF diet had a significant impact on the 12-item Short-Form Health Survey (SF-12) total score (p < 0.001) and physical function subscales (p = 0.006) as well as mental health (p < 0.001) when compared to the control diet. This implies that the ADMF diet increased both SF-12 total score and its subscales. The intervention led to improvements in HRQoL, physical function, and mental health. Additionally, significant improvements in BMI and weight were observed between the two groups pre- and post-study (p < 0.001). Anthropometric data, including body fat mass and waist circumference, showed a significant improvement (p < 0.001 and p = 0.029, respectively) before and after the study. However, there were no significant changes in fat-free mass (p = 0.936) and skeletal muscle mass (p = 0.841) between the two groups.

Conclusion

The study suggested that ADMF can improve HRQoL, mood lability, and expressed anger. It also showed that ADMF can reduce waist circumference, weight, and body fat mass in obese/overweight women.

Does the interplay of emotion-related personality traits and reproductive hormones predict individual variation in emotion recognition?

Person-related variation has been identified in many socio-cognitive domains, and there is evidence for links between certain personality traits and individual emotion recognition. Some studies, utilizing the menstrual cycle as a hormonal model, attempted to demonstrate that hormonal fluctuations could predict variations in emotion recognition, but with merely inconsistent findings. Remarkably, the interplay between hormone fluctuations and other person-related factors that could potentially influence emotion recognition remains understudied. In the current study, we examined if the interactions of emotion-related personality traits, namely openness, extraversion, and neuroticism, and the ovulatory cycle predict individual variation in facial emotion recognition in healthy naturally cycling women. We collected salivary ovarian hormones measures from N = 129 (n = 72 validated via LH test) women across their late follicular and mid-luteal phases of the ovulatory cycle. The results revealed a negative association between neuroticism scores and emotion recognition when progesterone levels (within-subject) were elevated. However, the results did not indicate a significant moderating influence of neuroticism, openness, and extraversion on emotion recognition across phases (late follicular vs. mid-luteal) of the menstrual cycle. Additionally, there was no significant interaction between openness or extraversion and ovarian hormone levels in predicting facial emotion recognition. The current study suggests future lines of research to compare these findings in a clinical setting, as both neuroticism and ovarian hormone dysregulation are associated with some psychiatric disorders such as premenstrual dysphoric disorder (PMDD).

Effect of chronic unpredictable stress in female Wistar-Kyoto rats subjected to progesterone withdrawal: Relevance for Premenstrual Dysphoric Disorder neurobiology

Premenstrual Dysphoric Disorder (PMDD) is related to an abrupt drop in progesterone and impairments in the HPA axis that cause anxiety. Suffering persons report higher daily-life stress and anxiety proneness that may contribute to developing PMDD, considered a chronic stress-related disorder. Here, we explored the effect of chronic unpredictable stress (CUS) in rats subjected to progesterone withdrawal (PW) and evaluated gene expression of HPA axis activation in the stress-vulnerable Wistar-Kyoto (WKY) rat strain that is prone to anxiety. Ovariectomized WKY rats were randomly assigned to CUS or Standard-housed conditions (SHC) for 30 days. To induce PW, animals received 2 mg/kg of progesterone on day 25th for 5 days; 24 h later, they were tested using the anxiety-like burying behavior test (BBT). After behavioral completion, rats were euthanized, and brains were extracted to measure Crh (PVN) and Nr3c1 (hippocampus) mRNA. Blood corticosterone and vasopressin levels were determined. Results showed that PW exacerbated anxiety-like behaviors through passive coping in CUS-WKY. PW decreased Crh-PVN mRNA and the Nr3c1-hippocampal mRNA expression in SHC. CUS decreased Crh-PVN mRNA compared to SHC, and no further changes were observed by PW or BBT exposure. CUS reduced Nr3c1-hippocampal gene expression compared to SHC animals, and lower Nr3c1 mRNA was detected due to BBT. The PW increased corticosterone in SHC and CUS rats; however, CUS blunted corticosterone when combined with PW+BBT and similarly occurred in vasopressin concentrations. Chronic stress blunts the response of components of the HPA axis regulation when PW and BBT (systemic and psychogenic stressors, respectively) are presented. This response may facilitate less adaptive behaviors through passive coping in stress-vulnerable subjects in a preclinical model of premenstrual anxiety.

Effect of modified alternate day fasting diet on the severity of premenstrual syndrome and health-related quality of life in women with overweight or obesity: a trial study protocol

INTRODUCTION

Premenstrual syndrome (PMS) includes a range of physical, behavioural and psychological symptoms and decreases women's health-related quality of life (HRQoL). It has been proposed that increased body mass index (BMI) is associated with menstrual problems and decreased HRQoL. The body fat amount plays a role in menstrual cycles by altering the oestrogen/progesterone ratio. Alternate day fasting as an unusual diet results in the improvement of anthropometric indices and reduction of body weight. This study aims to investigate the effect of a daily calorie restriction diet and a modified alternate day fasting diet on PMS and HRQoL.

METHODS AND ANALYSIS

This 8-week open-label parallel randomised controlled trial examines the impact of a modified alternate-day fasting diet and daily caloric restriction on the severity of PMS and HRQoL in obese or overweight women. Using simple random sampling, women between the ages of 18 years and 50 years and 25 ≤ BMI ˂ 40 who meet the inclusion and exclusion criteria will be chosen from the Kashan University of Medical Sciences Centre. Patients will be randomised, based on BMI and age through stratified randomisation. Then by the random numbers table, they are allocated to fasting (intervention) or daily calorie restriction (control) groups. Outcomes are chosen for the trial: the difference in the severity of PMS, HRQoL, BMI, body fat mass, fat-free mass, waist-to-hip ratio, waist circumference, hip circumference, per cent body fat, skeletal muscle mass and visceral fat area from baseline to 8 weeks.

ETHICS AND DISSEMINATION

The Kashan University of Medical Sciences Ethics Committee has approved the trial (IR.KAUMS.MEDNT.REC.1401.003) (17 April 2022). Results will be published in peer-reviewed academic journals and the participants will be informed via phone calls.

Associations with physical activity, sedentary behavior, and premenstrual syndrome among Chinese female college students

PURPOSE

Premenstrual syndrome refers to a set of distressing symptoms experienced before the menstrual flow, which can affect female students' behavior, cognitive abilities, mental health status, and academic performance. Identifying modifiable risk factors is essential to reduce the prevalence college students' premenstrual syndrome. We examined associations between premenstrual syndrome and physical activity and sedentary behavior in Chinese female college students.

METHODS

In this cross-sectional study, 315 female college students volunteered to participate at a university in Shanghai, China. We measured physical activity and sedentary behavior using the ActiGraph GT3X-BT and assessed premenstrual syndrome using the Premenstrual Symptoms Screening Tool. The data were statistically analyzed using SPSS 24.0 software, and the primary analysis methods included Kruskal-Wallis test and logistic regression analysis.

RESULTS

Among the 221 female college students who met the inclusion criteria, 148 (67.0%) had PMS while 73 (33.3%) did not. After controlling for confounding variables, moderate physical activity and moderate to vigorous intensity physical activity were significantly associated with premenstrual syndrome. There was no correlation between light-intensity physical activity, sedentary behavior, and premenstrual syndrome in the study.

CONCLUSION

Premenstrual syndrome is prevalent among Chinese female college students. Moderate physical activity and moderate-to-vigorous physical activity can be effective in reducing PMS symptoms.

The longitudinal predictive effect of self-reported frequency of premenstrual syndrome on depression: Findings from the Australian Longitudinal Study on Women's Health

Background

Previous studies have revealed a high comorbidity between premenstrual syndrome (PMS) and depression; however, whether PMS can longitudinally predict depression has not been examined in large sample studies.

Methods

This study surveyed 8,133 women from the 1973-78 cohort of the Australian Longitudinal Study on Women's Health. Participants completed seven repeated measurements at 3-year intervals starting in 2000 (aged 22-27 years). Binary logistic and multivariate ordered logistic regression models were used to examine the predictive role of self-reported frequency of PMS symptoms in 2000 on self-reported diagnosis of depression and frequency of depressive symptoms, respectively, for each follow-up survey.

Results

Self-reported frequency of PMS symptoms in the year 2000 predicted self-reported diagnosis of depression in most follow-up surveys. Specifically, compared to women who reported "never" had PMS symptoms in 2000, those who reported "often" had them were more likely to report a diagnosis of depression in 2006 (OR = 1.72), 2012 (OR = 1.88), 2015 (OR = 1.49), and 2018 (OR = 1.90); and those who reported "sometimes" had PMS symptoms in 2000 were more likely to report a diagnosis of depression in 2012 (OR =1.37) and 2018 (OR = 1.59). Furthermore, self-reported frequency of PMS symptoms in 2000 predicted self-reported frequency of depressive symptoms in each follow-up survey. Compared to women who reported "never" had PMS symptoms in 2000, those who reported "sometimes", or "often", had PMS symptoms reported depressive symptoms more frequently.

Conclusion

Self-reported frequency of PMS can predict the self-reported frequency of depressive symptoms and the subsequent diagnosis of depression.

Association between Neuroticism and Premenstrual Affective/Psychological Symptomatology

Neuroticism and premenstrual conditions share pleiotropic loci and are strongly associated. It is presently not known which DSM-5 symptoms of premenstrual syndrome/premenstrual mood disorder are associated with neuroticism. We enrolled 45 study participants to provide prospective daily ratings of affective ("depression", "anxiety, "anger", "mood swings") and psychological ("low interest", "feeling overwhelmed", and "difficulty concentrating") symptoms across two-three menstrual cycles (128 total cycles). Generalized additive modeling (gam function in R) was implemented to model the relationships between neuroticism and the premenstrual increase in symptomatology. Significance level was adjusted using the False Discovery Rate method and models were adjusted for current age and age of menarche. Results of the association analysis revealed that "low interest" (p ≤ 0.05) and "difficulty concentrating" (p ≤ 0.001) were significantly associated with neuroticism. None of the remaining symptoms reached statistical significance. The late luteal phase of the menstrual cycle is characterized by complex symptomatology, reflecting a physiological milieu of numerous biological processes. By identifying co-expression between neuroticism and specific premenstrual symptomatology, the present study improves our understanding of the premenstrual conditions and provides a platform for individualized treatment developments.

Investigation of the Relationship between Premenstrual Syndrome, and Childhood Trauma and Mental State in Adolescents with Premenstrual Syndrome

PURPOSE

This study was aimed at investigating the relationship between premenstrual syndrome (PMS), and childhood trauma and mental state in adolescents with PMS.

DESIGN AND METHODS

This descriptive study was conducted with 702 students between September 2020 and November 2020. An Information Form, the PMS Scale, the Childhood Trauma Questionnaire (CTQ) and Symptom Checklist (SCL)-90 were used as the data collection tools.

RESULTS

The mean scores the participants with PMS obtained from the Symptom Checklist (SCL)-90 and Childhood Trauma Questionnaire (CTQ) were higher than were those obtained by the participants without PMS. The Pearson correlation analysis revealed a positive and weak statistically significant relationship between the PMS Scale, and SCL-90 and CTQ.

CONCLUSIONS

The results of the study demonstrated that adolescents with PMS suffered from childhood traumas and mental problems more.

Trends in Research Related to Premenstrual Syndrome and Premenstrual Dysphoric Disorder From 1945 to 2018: A Bibliometric Analysis

Background: The global incidence of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) is increasing, with increasing suicide reports. However, the bibliometric analysis of global research on PMS and PMDD is rare. We aimed to evaluate the global scientific output of research on PMS and PMDD and to explore their research hotspots and frontiers from 1945 to 2018 using a bibliometric analysis methodology. Methods: Articles with research on PMS and PMDD between 1945 and 2018 were retrieved from the Web of Science Core Collection (WoSCC). We used the bibliometric method, CiteSpace V and VOSviewer to analyze publication years, journals, countries, institutions, authors, research hotspots, and trends. We plotted the reference co-citation network, and we used keywords to analyze the research hotspots and trends. Results: We identified 2,833 publications on PMS and PMDD research from 1945 to 2018, and the annual publication number increased with time, with fluctuations. Psychoneuroendocrinology published the highest number of articles. The USA ranked the highest among the countries with the most publications, and the leading institute was UNIV PENN. Keyword and reference analysis indicated that the menstrual cycle, depression and ovarian hormones were the research hotspots, whereas prevalence, systematic review, anxiety and depression and young women were the research frontiers. Conclusions: We depicted overall research on PMS and PMDD by a bibliometric analysis methodology. Prevalence and impact in young women, systematic review evaluations of risk factors, and the association of anxiety and depression with menstrual cycle phases are the latest research frontiers that will pioneer the direction of research in the next few years.

Association of socio-demographic, dietary and lifestyle factors with Premenstrual Syndrome (PMS) among undergraduate medical students of a tertiary care institute in Ahmedabad, Gujarat

Introduction:

The frequency, as well as the severity of the PMS (Pre-Menstrual Syndrome), varies from female to female based on various socio-demographic, dietary, and lifestyle factors. Nevertheless, the PMS is known to affect day-to-day functioning including interference with school/work productivity, relationships with friends, family, and colleagues. This is especially important for medical students where academic performance is much skillful and demanding.

Methodology:

The inclusion criteria for this cross-sectional survey were female medical students studying in one of the medical colleges of the city, having regular menstrual cycle (in the last three consecutive months) and willing to participate in the research. Students were assigned from each of the four professional years (First, Second, Third, and Final) through random sampling so that the desires sample size was achieved. The study used a pre-designed questionnaire, the “Premenstrual Symptoms Screening Tool (PSST)” (through Google form), that included 14 items assessing premenstrual symptoms of appetite, mood, sleep, anxiety and physical symptoms. It includes functional impairment items in five different domains as well.

Results:

The common symptoms seen in the respondents were anger/irritability (Mild n = 76, 46.3%; Moderate to severe n = 68, 41.4%) followed by physical symptoms which included headaches, joint or muscle pain, breast tenderness, gain in weight and bloating. The commonest functional impairment was college/work efficiency or productivity (n = 79, 48.2%). Alcohol and tobacco consumption had a significant association with PMDD. The type of diet did not have significant statistical association with PMS or PMDD.

Conclusion:

The most common symptoms seen were anger/irritability as well as physical symptoms like headache, breast tenderness etc., Factors like sleep, diet, exercise, yoga, alcohol and smoking were assessed.

Prevalence of premenstrual syndrome and its psychological effects among university students who participate and do not participate in resistance training

ABSTRACT The study aimed to investigate the prevalence and effects of premenstrual syndrome (PMS) on the psychological factors of university students who do and do not participate in resistance training. The initial sample consisted of 81 participants, and the prevalence of PMS was 64.2%. Forty women diagnosed with PMS were divided into two groups: women who participated in (GP) and did not participate in (GNP) resistance training. The intergroup comparison showed significant differences (with higher scores in the GNP) in the items: difficulty concentrating, lack of energy, and feeling under pressure, and they reported a greater influence of the symptoms on their family relationships. It is concluded that women who participate in resistance training have reduced indicators of some psychological symptoms of PMS.

Psychometric Testing of the Premenstrual Symptoms Questionnaire and the Association Between Perceived Injustice and Premenstrual Symptoms: A Cross-Sectional Study Among Japanese High School Students

Purpose

Premenstrual symptoms comprise a wide range of mood, behavioral, and physical symptoms occurring during the luteal phase. Perceived injustice is a belief linked to unfairness (ie, unnecessary suffering caused by illness). This study aimed to assess the validity and reliability of the Premenstrual Symptoms Questionnaire (PSQ), a patient-reported outcome measurement tool, and to examine the association between perceived injustice/perception of menstruation and premenstrual symptoms, as measured by the PSQ.

Materials and Methods

Of 1388 female students, we analyzed 879 students with regular menstrual cycles who completed the PSQ, the premenstrual dysphoric disorder (PMDD) scale, the Somatic Symptom Scale-8 (SSS-8), and the Injustice Experience Questionnaire-chronic (IEQ-chr). First, the PSQ was examined for evidence of reliability and validity. Next, we used multiple regression and multivariate logistic regression to investigate the association between perceived injustice and premenstrual symptoms, using PSQ score as both a continuous variable and a dichotomous variable (premenstrual disorders or not). Moreover, the association between PSQ score and perceived menstruation was tested using student's t-test and analysis of variance.

Results

In terms of reliability, Cronbach's α for PSQ score was 0.93. To assess structural validity, we used confirmatory factor analysis, which showed that the one-factor model and the two-factor model were a good fit. The PSQ showed good agreement with the PMDD scale. In terms of concurrent validity, PSQ total score correlated strongly with PMDD scale score, SSS-8 score, and IEQ-chr score (r = 0.88, 0.69, 0.57, respectively). IEQ-chr score predicted PSQ score (standardized regression coefficient = 0.53; P < 0.0001) and higher prevalence of premenstrual disorders (odds ratio: 1.15; 95% confidence interval: 1.12-1.19). Negative perception of menstruation was associated with premenstrual symptoms.

Conclusion

The PSQ showed sound psychometric properties among the adolescents in our sample. Perceived injustice and negative perception of menstruation were associated with premenstrual symptoms.

Magnitude of premenstrual dysphoric disorder and its correlation with academic performance among female medical and health science students at University of Gondar, Ethiopia, 2019: a cross-sectional study

OBJECTIVE

To assess the magnitude of premenstrual dysphoric disorder (PMDD) and associated factors among female students of the College of Medicine and Health Sciences, University of Gondar, Gondar, Ethiopia, 2019.

DESIGN

Institution-based cross-sectional study design.

SETTING

College of Medicine and Health Sciences, University of Gondar, Gondar, Ethiopia.

PARTICIPANTS

386 participants were recruited for self-administered interview using the stratified followed by simple random sampling technique.

MEASUREMENT

Data were collected by self-administered interview. Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) was used to measure PMDD. The Perceived Stress Scale (PSS) and the Oslo-3 social support are used to assess the factors. The data were checked, cleaned and entered into EpiData V.3.1 and exported to Statistical Package for Social Science (SPSS) V.21.0 for analysis. Bivariate and multivariable binary logistic regressions were used. OR with 95% CI was employed to see the strength of associations between dependent and independent variables. Variables with a p value <0.05 in multivariable logistic regression were declared as significantly associated.

RESULT

386 participants were involved in the study, with a response rate of 84.6%. The overall magnitude of PMDD in this study was 34.7% (30.3 to 39.1). Severe menstrual pain (adjusted OR (AOR)=2.82, 95% CI: 1.83 to 4.23), perception of an impact on academic performance due to menstrual pain (AOR=2.31, 95% CI: 1.23 to 4.32), and high perceived stress (AOR=3.52, 95% CI: 2.58 to 5.60) were significantly associated with PMDD disorder among female medical and health sciences students.

CONCLUSION

PMDD is high among female medical and health sciences students. Thus, it needs early screening and intervention especially for those who have severe menstrual pain, perceived to have an impact on academic performance and high perceived stress.

A potential relation between premenstrual symptoms and subjective perception of health and stress among college students: a cross-sectional study

Background

A majority of women from all cultures and socioeconomic levels experience myriad symptoms known as premenstrual syndrome during the days prior to menstruation. The present study investigated commonly reported symptoms in the premenstrual phase among college students. The authors further scrutinized potential factors, including subjective perceptions of health, which may be related to the premenstrual-symptom constellation.

Methods

We conducted a cross-sectional survey, which included 200 participants (mean age: 19.8 ± 0.1 years old). The subjects completed a rating of their premenstrual experiences relative to 46 symptoms in eight categories of the self-reporting menstrual distress questionnaire (MDQ) to evaluate the prevalence and severity of premenstrual symptoms. The participants also answered a standardized health questionnaire regarding subjective perceptions of health, self-rating stress, lifestyle, and demographic variables.

Results

Regardless of severity, the 10 symptoms most often occurring among the participants included skin disorders, irritability, fatigue, mood swings, general aches and pains, lowered school or work performance, backache, painful breasts, weight gain, and swelling. Stepwise multiple regression analysis revealed subjective perception of health (β = 0.28; p <  0.001) and self-rating stress (β = 0.18; p = 0.008) as the factors most strongly related to the MDQ total scores. In addition, the 19 women who evaluated themselves as “unhealthy and stressed” had greater prevalence of severe or extremely severe physical (general aches and pains) and psychosocial symptoms (confusion, lowered school or work performance, decreased efficiency, loneliness, anxiety, restlessness, mood swings, and depression), compared to the healthy and non-stressed women.

Conclusions

The present study indicates the prevalence of premenstrual symptoms, regardless of severity and number, among college students and suggests that negative subjective perceptions of health and stress may be related to the intensity of premenstrual symptomatology.
