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.

Prevalence and Associated Factors of Premenstrual Syndrome in Chinese Adolescent Girls

Epidemiological data on premenstrual syndrome (PMS) in Chinese adolescents are limited. This study reported the prevalence and associated factors of PMS in a large sample of Chinese adolescents. A total of 5099 adolescent girls who had menarche participated in the baseline survey of Shandong Adolescent Behavior and Health Cohort study in Shandong, China. A self-administered questionnaire was used to ask about PMS, age at menarche, menstrual cycle interval, menstrual flow length, menstrual regularity, period pain, body weight and height, trait anger, stressful life events, and demographics. The mean age of the sample was 15.19 years (SD = 1.32). The overall prevalence of PMS was 24.6%. The prevalence rates of PMS-anxiety, PMS-water retention, PMS-craving, and PMS-depression were 18.9%, 4.0%, 7.9%, and 11.5%, respectively. The most common symptoms were premenstrual irritability (54%) and fatigue (52.5%). Stepwise logistic regression showed that high levels of life stress (OR 2.26), high levels of trait anger (OR 4.65), alcohol consumption (OR 1.28), menstrual cycle interval ≤ 24 days (OR 1.45), and mild (OR 1.50), moderate (OR 2.57) or severe period pain (OR 4.84) were all significantly associated with increased likelihood of PMS. In conclusion, approximately 1 in 4 Chinese adolescent girls suffered from PMS. Multiple psychosocial and menstrual factors were associated with PMS. Further research is needed to understand developmental changes of PMS and its long-term impacts on psychosocial wellbeing in Chinese adolescent girls.

Emotion recognition and mood along the menstrual cycle

Previous studies have demonstrated menstrual cycle dependent changes in the recognition of facial emotional expressions, specifically the expression of fear, anger, sadness or disgust. While some studies demonstrate an improvement of emotion recognition performance during the peri-ovulatory phase, when estradiol levels peak, other studies demonstrate a deterioration of emotion recognition performance during the mid-luteal phase, when progesterone levels peak. It has been hypothesized, that these changes in emotion recognition performance mirror mood changes along the menstrual cycle. In the present study, we investigate, whether changes in emotion recognition performance along the menstrual cycle are mediated by mood changes along the menstrual cycle. In a combined cross-sectional and longitudinal study design, two large samples of women completed an emotion recognition task, as well as several mood questionnaires during their menses, peri-ovulatory or mid-luteal cycle phase. 65 women completed the task thrice, once during each cycle phase, order counterbalanced. In order to control for potential learning effects, a sample of 153 women completed the task only once in one of the three cycle phases. In both samples, results demonstrated no significant changes in emotion recognition performance along the menstrual cycle, irrespective of the performance measure investigated (accuracy, reaction time, frequency of emotion classifications) and irrespective of the emotion displayed. Bayesian statistics provided very strong evidence for the null hypothesis, that emotion recognition does not change along the menstrual cycle. There was also no moderation of emotion recognition changes along the menstrual cycle by mood changes along the menstrual cycle. Mood changes along the menstrual cycle followed the expected pattern with highest positive affect and least premenstrual symptoms around ovulation and lowest positive affect, but strongest premenstrual symptoms during menses. Interestingly, premenstrual symptoms were negatively related to estradiol, suggesting a protective effect of estrogen during the luteal cycle phase against mood worsening during the premenstrual phase.

Effect of γ-tocopherol supplementation on premenstrual symptoms and natriuresis: a randomized, double-blind, placebo-controlled study

BACKGROUND

This randomized, double-blind, placebo-controlled study aimed to investigate the effects of γ-tocopherol (Toc) supplementation on premenstrual symptoms and natriuresis.

METHODS

We enrolled 51 Japanese women with premenstrual symptoms, particularly those who showed increased symptoms induced by water retention during the luteal phase compared with the follicular phase. Premenstrual symptoms were recorded in the first cycle's postmenstrual follicular phase; physical measurements and urine collection were conducted during the 48-h run-in period. The test supplement, which contained 180 mg of γ-Toc or placebo, was orally administered twice a day for 7 days during the luteal phase of the first and second cycles in a crossover manner. The same evaluation was conducted during the luteal phase, beginning in the morning of the sixth day of supplement administration.

RESULTS

Compared with placebo intake, γ-Toc intake significantly reduced "fatigue" and "irritability/anger" symptoms. Furthermore, compared with placebo intake, γ-Toc intake significantly reduced the thigh circumference. Regarding the "swelling of the legs" and "heavy legs" symptoms and the thigh circumference, the biphasic trend of increasing and decreasing values in the daytime and morning, respectively, during the follicular phase was not observed at the luteal phase with placebo intake. Contrastingly, γ-Toc intake resulted in significantly lower values in the morning than placebo intake. The mean difference in 24-h urinary sodium excretion between γ-Toc and placebo intake was 10.6 mEq (95% confidence interval (CI): -0.1, 21.4, p = 0.05, power 55%). Plasma γ-Toc and its metabolite γ-carboxyethyl hydroxychroman (CEHC) levels were significantly higher with γ-Toc intake than with placebo intake. There were no significant between-supplement differences in serum electrolyte levels or cumulative urinary potassium excretion.

CONCLUSION

γ-Toc intake could effectively alleviate certain premenstrual syndrome symptoms, particularly those related to water retention during the luteal phase. Furthermore, the underlying mechanism may involve the diuretic effect of γ-CEHC, which is a γ-Toc metabolite.

Associations of premenstrual symptoms with daily rumination and perceived stress and the moderating effects of mindfulness facets on symptom cyclicity in premenstrual syndrome

Subthreshold premenstrual symptoms can be impairing even if the diagnostic criteria for premenstrual dysphoric disorder (PMDD) are not reached. Previous research suggests shared psychological risk factors without a clear differentiation of premenstrual syndrome (PMS) from PMDD. This study focuses on a sample with a wide range of premenstrual symptoms not reaching PMDD-criteria and aims to investigate within-person associations of premenstrual symptoms with daily rumination and perceived stress during the late luteal phase as well as cycle-phase specific associations of habitual mindfulness including present-moment-awareness and acceptance with premenstrual symptoms and impairment. Fifty-six naturally cycling women with self-reported premenstrual symptoms completed an online diary on premenstrual symptoms, rumination and perceived stress over two consecutive menstrual cycles, and baseline questionnaires on habitual present-moment-awareness and acceptance. Multilevel analyses revealed cycle-related variations in premenstrual symptoms and impairment (all ps < .001). Higher within-person levels of core and secondary premenstrual symptoms during the late luteal phase predicted increased daily rumination and perceived stress (all ps < .001) and increased somatic symptoms predicted increased rumination (p ≤ .018). Higher habitual present-moment-awareness was linked to lower premenstrual symptom and impairment levels toward the late luteal phase whereas higher habitual acceptance was associated with lower premenstrual functional impairment (p ≤ .015). Premenstrual symptom increases during the late luteal phase in women with PMS seem to be linked to increased daily rumination and perceived stress. Trait present-moment-awareness and acceptance in turn seem to reflect protective factors against premenstrual distress and may represent useful targets for interventions.

Understanding comorbidity between eating disorder and premenstrual symptoms using a network analysis approach

Eating disorder symptoms are associated with ovarian hormones and fluctuate predictably across the menstrual cycle. However, the specific symptoms that underlie these associations remain unclear. The current study aims to examine which specific eating disorder and premenstrual symptoms confer risk and maintain comorbidity using network analysis. Eating disorder and premenstrual symptoms were measured using the Eating Pathology Symptoms Inventory and the Daily Record of Severity of Problems, respectively, in a large sample of young adult females. Network analysis was used to explicate the structure of eating and premenstrual symptom networks separately and together. Eating disorder networks replicated previous literature and identified body dissatisfaction as a core feature, but was unique in identifying monitoring calories as an additional core feature. Central symptoms identified in the premenstrual symptom network were symptoms interference with daily life and activities and negative emotions brought on by hormone changes. Bridge symptoms between networks were identified as relating to eating behaviors, interference with daily activities, joint and muscle pain, and negative emotions brought on by hormone changes. This study suggests that the links between eating disorder and premenstrual symptoms extend past their individual effects on eating behavior and are indicative of a shared underlying mechanism.

A DSM-5-based tool to monitor concurrent mood and premenstrual symptoms: the McMaster Premenstrual and Mood Symptom Scale (MAC-PMSS)

Background

Despite high co-morbidity between premenstrual dysphoric disorder and mood disorders, there is a gap of research-based tools to monitor concurrent premenstrual and mood symptoms. In this study, we developed a new DSM-5-based questionnaire to prospectively monitor concurrent premenstrual and mood symptoms.

Methods

Fifty-two females with bipolar or major depressive disorder, ages 16–45, were enrolled in the study. Participants completed two months of prospective symptom charting including the McMaster Premenstrual and Mood Symptom Scale (MAC-PMSS) and the Daily Record of Severity of Problems (DRSP). At the end of the prospective charting, participants also completed the Montgomery-Åsberg Depression Rating Scale (MADRS), Hamilton Depression Rating Scale (HDRS) and the Young Mania Rating Scale (YMRS). The MAC-PMSS was correlated with the DRSP, MADRS, HDRS and YMRS.

Results

All individual items of the MAC-PMSS correlated strongly with the individual DRSP scores (all p < 0.001). The mood section of the MAC-PMSS also significantly correlated with MADRS (r = 0.572; p < 0.01), HDRS (r = 0.555; p < 0.01) and YMRS scores (r = 0.456; p < 0.01).

Conclusions

The MAC-PMSS is a reliable to tool to measure concurrent mood and premenstrual symptoms in women with mood disorders.

Eye movement pattern of attention bias to emotional stimuli in women with high premenstrual symptoms

BACKGROUND AND OBJECTIVES

Premenstrual Syndrome (PMS) refers to a group of symptoms linked to the menstrual cycle. Women with PMS have cognitive mode of rumination, which leads to their attention bias to emotional stimuli. This study investigated the biases for emotional information in women with high premenstrual symptoms (HPMS) compared with women with low premenstrual symptoms (LPMS).

METHODS

A total of 38 women with HPMS and 44 women with LPMS completed self-report questionnaires and a free viewing task with eye-tracking technology.

RESULTS

The questionnaire results indicate that women in the HPMS group had higher levels of rumination than those in the LPMS group. The eye-tracking results show that women in the HPMS group had an orientation bias towards negative emotional stimuli in the early cognitive process. In the late cognitive process, women in the HPMS group had accelerated attentional disengagement to positive emotional stimuli and difficult attentional disengagement to negative emotional stimuli. Further correlation analysis revealed positive relationships between the scores of initial fixation latency bias of positive pictures in premenstrual phase and the scores of symptom rumination in both groups and between the scores of initial fixation latency bias of positive pictures in premenstrual phase and the scores of brooding in HPMS group.

LIMITATIONS

This study used a retrospective questionnaire to assess the symptoms of PMS.

CONCLUSIONS

Women with HPMS had impaired attentional engagement and disengagement to emotional stimuli compared with women with LPMS, and it may be related to their cognitive mode of rumination.

Psychometric Properties of a DSM-5-Based Screening Tool for Women's Perceptions of Premenstrual Symptoms

A premenstrual screening tool is needed when time constraints and attrition limit the feasibility of daily ratings. The present study examines the utility of a novel, 33-item, retrospective, dimensional, DSM-5-based, screening measure developed to explore women's perceptions of premenstrual symptomatology. This is the first measure that examines perception of impairment for each DSM-5 symptom and assesses the frequency criterion. Participants (N = 331) reported symptoms ranging from none to a level consistent with a provisional DSM-5 diagnosis of Premenstrual Dysphoric Disorder (PMDD). Initial psychometric properties indicated a five-factor structure: (1) affective symptoms; (2) fatigue, sleep, and anhedonia; (3) symptom frequency; (4) impairment and severity of appetite change and physical symptoms; and (5) difficulty concentrating. The total symptom scale and the frequency, severity, and impairment subscales demonstrated high internal consistency. Strong correlations between this dimensional measure and other retrospective and prospective premenstrual symptom measures suggest strong convergent, concurrent, and predictive validity. Premenstrual symptom groups created using this screening measure (minimal, mild/moderate, severe) differed on other retrospective and prospective measures of premenstrual symptoms. There was evidence of divergent validity and lack of an acquiescence bias. We also report data describing women's perceptions of the frequency, level of impairment, and level of severity for each DSM-5 PMDD symptom over a 12-month period and discuss implications for future research on premenstrual phenomenology. Initial evidence for the reliability and construct validity of this symptom screening measure suggests potential value for assessing premenstrual symptomatology in research and practice.

Associations between sleep habits and interference of premenstrual symptoms in athletic performance in Japanese adolescent athletes: a cohort study over a 2-year period

Premenstrual symptoms are common problems among female high-school and college athletes. This prospective study investigated associations between sleep habits and interference of premenstrual symptoms in athletic performance among Japanese adolescent athletes. A school-based survey on menstruation and school life was conducted among 623 female high-school students in 2015 and 2016, and data from the two surveys were connected. In total, 262 students completed the questionnaire in both years. We recruited 108 of those students who were athletes with regular menstrual cycles. Participants completed a questionnaire about their premenstrual symptoms and lifestyle habits. The prevalence of short sleep duration (<8 h) was high (95.4%). The difference in premenstrual symptom severity in individual students between the first and second years was not significant (p > .05). Premenstrual symptoms were less associated with disturbance in 'athletic performance in training or competition' in the second year than the first. 'Longer sleeping time' in the first year was associated with lower risk of increased interference of premenstrual symptoms in athletic performance in the second year (odds ratio 0.982, 95% confidence interval: 0.970-0.994). Shorter sleep duration may therefore have an effect on premenstrual symptoms' interference with athletic performance among Japanese adolescents.

Poor sleep and emotion dysregulation mediate the association between depressive and premenstrual symptoms in young adult women

A large portion of reproductive-aged women report experiencing distressing premenstrual symptoms. These symptoms can be exacerbated by concurrent mood problems and contribute to long-term depressive risk. However, difficulty sleeping and regulating emotional responses are also associated with the premenstrual phase and represent additional, well-established risk factors for depression. The aim of this study was to investigate whether habitual sleep problems and emotion regulation strategies serve to mediate the relationship between mood and premenstrual symptoms in non-treatment-seeking young women. Participants included 265 adult women between the ages of 18 and 25 who provided retrospective self-reports of depressive symptoms, habitual sleep quality, and premenstrual symptoms for the past month. Trait-based difficulties in regulating emotions were also assessed. Greater depressive symptoms significantly predicted greater premenstrual symptoms and both poor sleep and ineffective emotion regulation were shown to mediate this relationship. Poor sleep may enhance experience of premenstrual symptoms via its well-established impact on physical, cognitive, and/or affective functioning. Similarly, an inability to effectively regulate emotional responses in general may exacerbate experience or perception of somatic and mood symptoms during the premenstrual period, contributing to mood disturbances and risk. Findings require replication in future studies using prospective designs and more diverse samples of women.

Menstrual characteristics, disorders and associated risk factors among female international students in Zhejiang Province, China: a cross-sectional survey

Background

Until now, no previous study has addressed the menstrual patterns among female international students in China. In this present study, our objectives are to ascertain the menstrual characteristics and address the menstrual problems together with their associated risk factors among international students in China.

Methods

A cross-sectional survey was carried out with 500 previously piloted self-structured questionnaires which were administered to female international students enrolled in 15 universities in Zhejiang Province, China from May 2–August 31, 2016. Participants were required to provide answers to a semi-structured questionnaire which asked questions about their socio-demographics and their menstrual characteristics while in their home countries. Relevant changes in their menstrual pattern in terms of amount of flow and duration, regularity, length and suggestive symptoms for premenstrual syndrome in the months after coming to reside in China were also inquired. Respondents indicated changes in eating habits and selected stressors relevant to them from a given list. Their stress levels were assessed and further categorized with the help of the Perceived Stress Scale (PSS). Measurements for the main outcomes included the characteristics of menstrual patterns after arrival in China, stress levels, stressors and new lifestyle patterns.

Results

Four hundred and nine (81.8%) out of the 500 questionnaires met the criteria and constituted the population for this study. The respondents’ mean age was 21.405 years. Almost half of our respondents (49.1%) reported varying changes in their menstrual pattern after arrival to China. Although, menstrual regularity, normal menstrual length (21-35 days) and duration of flow (3–7 days) remained fairly normal among most of the respondents, disorders like premenstrual symptoms (PMS) (33.82%); abnormal amount (17.97%) and dysmenorrhea (16.38%) were prevalent. There was a significant association between high stress (PSS > 20) and menstrual change 0R = 1.636, 95% CI 1.051–2.547, p = 0.029) and dysmenorhea (p = 0.037). Common stressors included language barrier 81(25.88%), food 64(20.45%), and loneliness 56(17.89%).

Conclusion

Menstrual disorders are high among international students in China. We established premenstrual symptoms as the most common menstrual disorder. High levels of stress (PSS > 20) emanating from factors including the language barrier, diet and loneliness was significantly related to the disruptions in their menstruation.

Association between Vitamin D Status and Premenstrual Symptoms

BACKGROUND

Premenstrual symptoms are experienced by up to 95% of women, and few treatments are available. Previous studies suggest that 25-hydroxyvitamin D (25(OH)D) may be associated with the severity of premenstrual symptoms, but the findings have been inconclusive.

OBJECTIVE

The objective of this study was to determine whether vitamin D status is associated with the severity of individual premenstrual symptoms.

DESIGN/PARTICIPANTS

Cross-sectional analysis of 998 women aged 20 to 29 years recruited at the University of Toronto campus from 2004 through 2010.

MAIN OUTCOME MEASURES

Participants provided data on their premenstrual symptoms in a premenstrual symptom questionnaire. Fasting overnight blood samples were collected, and plasma 25(OH)D was measured. Participants with plasma 25(OH)D concentrations <20 ng/mL were considered to have inadequate vitamin D status, and those with ≥20 ng/mL, adequate vitamin D status.

STATISTICAL ANALYSES PERFORMED

Multinomial logistic regressions were used to calculate the odds ratio (OR) and 95% confidence interval for the associations between vitamin D status and the severity of 15 premenstrual symptoms. Adjustments were made for age, body mass index, ethnicity/race, physical activity, hormonal contraceptive use, season of blood draw, use of analgesics, and calcium intake.

RESULTS

Compared with participants with adequate vitamin D status, those with inadequate vitamin D status had an increased risk (odds ratio [OR]; 95% CI) of experiencing the following mild symptoms: confusion (OR=1.72; 95% CI, 1.14 to 2.59) and desire to be alone (OR=1.47; 95% CI; 1.03 to 2.10), as well as the following moderate/severe symptoms: cramps (OR=1.50; 95% CI, 1.02 to 2.21), fatigue (OR=1.51; 95% CI, 1.04 to 2.21), anxiety (OR=1.63; 95% CI, 1.02 to 2.63), confusion (OR=2.23; 95% CI, 1.18 to 4.21), and sexual desire (OR=1.65; 95% CI, 1.09 to 2.51). Vitamin D status was not associated with other premenstrual symptoms (acne, bloating, mood swings, increased appetite, headache, clumsiness, insomnia, depression, or nausea).

CONCLUSION

Findings suggest that inadequate vitamin D status may be associated with increased severity of some, but not all, premenstrual symptoms.

The inconvenience due to women's monthly bleeding (ISY) survey: a study of premenstrual symptoms among 5728 women in Europe

OBJECTIVES

The aim of the ISY study was to investigate the prevalence of menstrual-related symptoms prior to and/or during menstrual or withdrawal bleeding among women from 12 European countries.

METHODS

A 15-min quantitative online survey was conducted in two waves from February to September 2015 among 5728 women aged between 18 and 45 years, with an equal distribution of women using a combined hormonal contraceptive, including regular combined oral contraceptives (COCs) (CHC group, n = 2739) and women using a non-hormonal contraceptive or no contraceptive (non-HC group, n = 2989).

RESULTS

The prevalence of at least one menstrual-related symptom was high in CHC users (93%) and in non-HC users (95%) (p < .0001) and the average number of symptoms reported was 5.3 vs. 5.9, respectively, (p < .0001). Pelvic pain, bloating/swelling, irritability and mood swing were reported in more than half of the women in both groups. Although generally modest, symptom severity was higher in non-HC users, except for headache. Overall, during the last four cycles, 60-75% of women did not require a treatment for most symptoms but headaches and pelvic pain. Mood swings/irritability, water retention/weight gain, lack of energy/mood swings and lack of energy/irritability were common symptoms that frequently co-occurred. No associations were reported between symptoms and age, educational qualifications or women's desire to reduce the frequency of menstruation.

CONCLUSIONS

Premenstrual and menstrual symptomatology was less frequent, less numerous and less severe (except for headache) in women using CHCs; however, it remains a common concern. Reducing the frequency of menstrual periods could reduce withdrawal-related symptoms.

Hormonal contraceptive use and prevalence of premenstrual symptoms in a multiethnic Canadian population

Background

Hormonal contraceptive use may be associated with a reduction in some premenstrual symptoms, however, the evidence remains equivocal. The objectives of the present study were to investigate the associations between ethnicity and hormonal contraceptive use with premenstrual symptoms.

Methods

One thousand one hundred two women participating in the Toronto Nutrigenomics and Health Study provided data on their premenstrual symptoms and hormonal contraceptive use. Severity of symptoms was classified as none, mild, moderate, or severe. Prevalence of premenstrual symptoms was determined in the total population and among major ethnic groups. Logistic regressions were used to determine the association between ethnicity and prevalence of premenstrual symptoms. Logistic regressions were used to determine the associations between hormonal contraceptive use, and premenstrual symptoms, adjusting for ethnicity and other covariates.

Results

Prevalence of individual symptoms varied, and the most commonly reported were cramps (75%), bloating (75%), mood swings (73%), increased appetite (64%), and acne (62%). Prevalence of cramps differed between ethnic groups with East Asians reporting a lower prevalence than Caucasians and South Asians (p < 0.05). Use of hormonal contraceptives was associated with a lower RR (95% CI) of experiencing moderate/severe: cramps (0.82, 0.72-0.93), clumsiness (0.22, 0.07-0.73), confusion (0.22, 0.09-0.54) and desire to be alone (0.45, 0.28-0.73). Hormonal contraceptive use was not associated with the risk of premenstrual symptoms at mild severity. Hormonal contraceptive use was not associated with symptoms of anxiety, bloating, mood swings, increased appetite, acne, fatigue, sexual desire, depression, nausea, headache and insomnia.

Conclusion

This study demonstrates that East Asians may be at a lower risk of experiencing premenstrual cramps and that hormonal contraceptive use is associated with a lower risk of experiencing many, but not all, premenstrual symptoms at moderate/severe severity.

Cortisol awakening response is blunted and pain perception is increased during menses in cyclic women

BACKGROUND AND AIMS

The incidence of menstrual symptoms is reported to be as high as 90% in cyclic women. These symptoms, including anxiety and pain, might be associated with cortisol, as its receptors are widely distributed in the brain areas associated with behavior. Therefore, the current study aimed to assess the cortisol awakening response (CAR) throughout the menstrual cycle and correlate it with pain perception and trait anxiety.

MATERIALS AND METHODS

CAR was assessed by measuring salivary cortisol at 0, 15, 30, and 60min following awakening in the same women (n=59, age 22.2±0.37years) at various stages of the menstrual cycle (menses, midcycle, luteal and premenstrual phases). Progesterone and estradiol concentrations were also determined in saliva samples to assess cyclic changes. Self-reported pain, trait anxiety, and menstrual symptoms were assessed by visual analog scale (VAS), state-trait anxiety inventory (STAI-T), and the Daily Record of Severity of Problems (DRSP), respectively.

RESULTS

Estradiol was significantly elevated during the midcycle period and remained high during the early luteal phase (p<0.05). Progesterone was increased during the luteal phase (p<0.05). Post-awakening cortisol values increased during midcycle, luteal phase, and premenstrual phase (p<0.05, classical CAR), but not during the menses (p>0.05, blunted or flat CAR). Positive and significant correlations were found between cortisol and estradiol (R²=0.322; p=0.000), cortisol and progesterone (R²=0.156; p=0.000), and estradiol and progesterone (R²=0.349; p=0.001). Premenstrual symptom scores were higher in the menses and premenstrual phases than in the midcycle and luteal phases (p<0.001). Pain perception was the highest during the menses followed by the premenstrual phase (p<0.01).

CONCLUSIONS

CAR was blunted during the menses, suggesting that cortisol might play a phase-specific role in the regulation of the cycle. Additionally, premenstrual symptoms, including pain, were more severe when ovarian steroid levels reduced (i.e., menses and the premenstrual phase).

A specific profile of luteal phase progesterone is associated with the development of premenstrual symptoms

There is a consensus that the development of premenstrual dysphoric states is related to cyclical change in gonadal hormone secretion during the menstrual cycle. However, results from studies seeking to link symptom severity to luteal phase progesterone concentration have been equivocal. In the present study we evaluated not only the absolute concentrations of progesterone but also the kinetics of the change in progesterone concentration in relation to development of premenstrual symptoms during the last 10days of the luteal phase in a population of 46 healthy young adult Brazilian women aged 18-39 years, mean 26.5±6.7years. In participants who developed symptoms of premenstrual distress, daily saliva progesterone concentration remained stable during most of the mid-late luteal phase, before declining sharply during the last 3days prior to onset of menstruation. In contrast, progesterone concentration in asymptomatic women underwent a gradual decline over the last 8days prior to menstruation. Neither maximum nor minimum concentrations of progesterone in the two groups were related to the appearance or severity of premenstrual symptoms. We propose that individual differences in the kinetics of progesterone secretion and/or metabolism may confer differential susceptibility to the development of premenstrual syndrome.

Premenstrual symptoms and smoking-related expectancies

Given that prior research implicates smoking abstinence in increased premenstrual symptoms, tobacco withdrawal, and smoking behaviors, it is possible that women with more severe premenstrual symptoms have stronger expectancies about the effects of smoking and abstaining from smoking on mood and withdrawal. However, such relations have not been previously explored. This study examined relations between premenstrual symptoms experienced in the last month and expectancies that abstaining from smoking results in withdrawal (i.e., smoking abstinence withdrawal expectancies), that smoking is pleasurable (i.e., positive reinforcement smoking expectancies), and smoking relieves negative mood (i.e., negative reinforcement smoking expectancies). In a cross-sectional design, 97 non-treatment seeking women daily smokers completed self-report measures of smoking reinforcement expectancies, smoking abstinence withdrawal expectancies, premenstrual symptoms, mood symptoms, and nicotine dependence. Affect premenstrual symptoms were associated with increased negative reinforcement smoking expectancies, but not over and above covariates. Affect and pain premenstrual symptoms were associated with increased positive reinforcement smoking expectancies, but only affect premenstrual symptoms remained significant in adjusted models. Affect, pain, and water retention premenstrual symptoms were associated with increased smoking abstinence withdrawal expectancies, but only affect premenstrual symptoms remained significant in adjusted models. Findings from this study suggest that addressing concerns about withdrawal and alternatives to smoking may be particularly important in women who experience more severe premenstrual symptoms, especially affect-related changes.

Reproducibility of hormone-driven regional grey matter volume changes in women using SPM8 and SPM12

Aim of this work was to evaluate the reproducibility of hormone driven regional grey matter volume differences in women, and their correlations with premenstrual symptoms, as determined by voxel-based morphometry (VBM). After data quality control, a total of 138 T1-weighted MR images were included in this longitudinal study, and were analyzed as three different subgroups. Women with a natural menstrual cycle were scanned at three time-points: follicular, ovulatory and luteal phase. Two groups of women, using androgenic and anti-androgenic hormonal contraceptives, respectively, were scanned twice: during the pill-free week and during pill intake. Additionally, subjects were asked to complete a "daily rating of severity of problems" questionnaire, to quantify premenstrual symptoms. All data were analyzed using SPM8 and SPM12 with identical parameter settings. In the natural menstrual cycle group, the regional grey matter volume of the insula is larger at ovulation, as compared to the luteal phase. Premenstrual symptoms correlate differently with regional grey matter volumes between women with a natural cycle and hormonal contraceptive users. Changes in hormonal environment can to various extents affect VBM findings in women. We suggest that researchers take these confounding factors into account while applying this technique, to avoid heterogeneity in data acquisition and to safeguard the sensitivity of findings. Additionally, we suggest validating the consistency of results using more than one software package.

Clinical features of and risk factors for major depression with history of postpartum episodes in Han Chinese women: A retrospective study

BACKGROUND

We sought to investigate the clinical features of and risk factors for recurrent major depression (MD) with history of postpartum episodes (PPD) in Han Chinese women and the differences between first-onset postpartum MD (MD that has its first lifetime depressive episode in the postpartum period) and first-onset non-postpartum MD (MD with history of PPD and has its first lifetime depressive episode in a period other than postpartum).

METHODS

Data were derived from the China, Oxford and Virginia Commonwealth University Experimental Research on Genetic Epidemiology (CONVERGE) study (N=6017 cases) and analyzed in two steps. We first examined the clinical features of and risk factors for MD patients with (N=981) or without (N=4410) a history of PPD. We then compared the differences between first-onset postpartum MD (N=583) and first-onset non-postpartum MD (N=398) in those with a history of PPD. Linear, logistic and multinomial logistic models were employed to measure the associations.

RESULTS

A history of PPD was associated with more guilt feelings, greater psychiatric comorbidity, higher neuroticism, earlier onset and more chronicity (OR 0.2-2.8). Severe premenstrual symptoms (PMS) and more childbirths increased the risk of PPD, as did a family history of MD, childhood sexual abuse, stressful life events and lack of social support (OR 1.1-1.3). In the MD with history of PPD subsample, first-onset postpartum MD was associated with fewer recurrent major depressive episodes, less psychiatric comorbidity, lower neuroticism, less severe PMS and fewer disagreements with their husbands (OR 0.5-0.8), but more childbirths (OR 1.2).

LIMITATIONS

Data were obtained retrospectively through interview and recall bias may have affected the results.

CONCLUSIONS

MD with history of PPD in Han Chinese women is typically chronic and severe, with particular risk factors including severe PMS and more childbirths. First-onset postpartum MD and first-onset non-postpartum MD can be partly differentiated by their clinical features and risk factors, but are not clearly distinctive.

Stability of resting state networks in the female brain during hormonal changes and their relation to premenstrual symptoms

Resting-state fMRI is a promising imaging technique to evaluate functions in the human brain in health and disease. Different hormonal stages of the female menstrual cycle and hormonal contraceptives use affect results in task-based fMRI; it is however not yet clarified whether resting state networks are also altered. A population of 18 women with a natural cycle, and 19 women using hormonal contraceptives was examined in a longitudinal study-design. The natural cycle group was scanned at 3 time-points (follicular phase, ovulation, luteal phase), and the contraceptives group was scanned twice (inactive pill-phase, active pill-phase). Blood samples were acquired to evaluate hormonal concentrations, and premenstrual symptoms were assessed through daily record of severity of problems questionnaires. Results show no major alterations in the default mode network and the executive control network between different hormonal phases, across or within groups. A positive correlation of functional connectivity in the posterior part of the default mode network (DMN) was found with premenstrual-like symptoms in the hormonal contraceptives group. Using the current methodology, the studied resting state networks seem to show a decent stability throughout menstrual cycle phases. Also, no effect of hormonal contraceptive use is found. Interestingly, we show for the first time an association of DMN alterations with premenstrual-like symptoms, experienced during the inactive pill-phase by a sub-population of women.

Effect of endometrial ablation on premenstrual symptoms

STUDY OBJECTIVE

To evaluate the effect of endometrial ablation on 6 premenstrual symptoms for up to 1 year after treatment.

DESIGN

Prospective cohort of 59 women awaiting endometrial ablation (Canadian Task Force classification II-2).

SETTING

University tertiary care hospital.

PATIENTS

Adult women of childbearing age awaiting endometrial ablation for heavy menstrual bleeding were recruited through the gynecology clinic of the Centre Hospitalier Universitaire de Sherbrooke. Fifty-nine patients were recruited, of whom 9 were excluded. Women were eligible to participate after an initial self-evaluation of ≥ 3 out of 10 for at least 1 premenstrual symptom.

INTERVENTIONS

Women underwent endometrial ablation using the microwave, impedance-controlled, or rollerball technique.

MEASUREMENTS AND MAIN RESULTS

Women had to fill out 2 surveys at 3 time points: before surgery, 4 months after surgery, and 12 months after surgery. The first survey consisted of visual analog scales for self-evaluation of 6 premenstrual symptoms (i.e., irritability, agitation/anxiety, depression/sadness, headache, swelling/bloating, and breast tenderness), and the second evaluated the heaviness of menstrual bleeding. The severity of all 6 symptoms decreased significantly (p < .025) up to 1 year after endometrial ablation. The greatest improvement was seen in swelling/bloating, with mean decreases of 4.1 on a scale of 10 at the 4-month follow-up and 3.1 at the 12-month follow-up. Women who reported the most severe symptoms before surgery appeared to have greater improvement compared with women with milder symptoms. Significant improvements were nevertheless observed in the mild severity subgroup for 4 of the 6 symptoms studied (i.e., irritability, depression, swelling/bloating, and breast tenderness).

CONCLUSION

Women reported significant improvement for the 6 premenstrual symptoms for up to 1 year following an endometrial ablation for heavy menstrual bleeding. The improvement of these symptoms appears to be linked to the efficacy of the procedure.

Ecological validity and clinical utility of Patient-Reported Outcomes Measurement Information System (PROMIS®) instruments for detecting premenstrual symptoms of depression, anger, and fatigue

OBJECTIVE

This study examined the ecological validity and clinical utility of NIH Patient Reported-Outcomes Measurement Information System (PROMIS®) instruments for anger, depression, and fatigue in women with premenstrual symptoms.

METHODS

One-hundred women completed daily diaries and weekly PROMIS assessments over 4weeks. Weekly assessments were administered through Computerized Adaptive Testing (CAT). Weekly CATs and corresponding daily scores were compared to evaluate ecological validity. To test clinical utility, we examined if CATs could detect changes in symptom levels, if these changes mirrored those obtained from daily scores, and if CATs could identify clinically meaningful premenstrual symptom change.

RESULTS

PROMIS CAT scores were higher in the pre-menstrual than the baseline (ps<.0001) and post-menstrual (ps<.0001) weeks. The correlations between CATs and aggregated daily scores ranged from .73 to .88 supporting ecological validity. Mean CAT scores showed systematic changes in accordance with the menstrual cycle and the magnitudes of the changes were similar to those obtained from the daily scores. Finally, Receiver Operating Characteristic (ROC) analyses demonstrated the ability of the CATs to discriminate between women with and without clinically meaningful premenstrual symptom change.

CONCLUSIONS

PROMIS CAT instruments for anger, depression, and fatigue demonstrated validity and utility in premenstrual symptom assessment. The results provide encouraging initial evidence of the utility of PROMIS instruments for the measurement of affective premenstrual symptoms.

The role of anxiety sensitivity in the experience of menstrual-related symptoms reported via daily diary

The current study examined the interactive effects of Anxiety Sensitivity (AS) and menstrual cycle phase in the experience of menstrual-related symptoms. Participants were 55 community women who completed prospective tracking of menstrual-related symptoms across at least one full menstrual cycle using the Daily Record of Severity of Problems (DRSP) and completed the Menstrual Distress Questionnaire (MDQ) once in their premenstrual and follicular cycle phases. Results revealed that women with higher levels of AS reported greater menstrual-related symptoms, regardless of cycle phase, as compared to women with lower levels of AS. These findings suggest that AS may be an important psychological factor involved in the experience of psychological and somatic symptoms across the menstrual cycle. Results are consistent with previous literature documenting the role of AS in menstrual-related symptoms as well as in other physical health conditions.
