Premenstrual syndrome in Thai nurses

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

Dysmenorrhea and Quality of Life: A Cross-Sectional Survey Among Medical Students

Background: Primary dysmenorrhea is a prevalent condition characterized by menstrual pain in the absence of pelvic pathology, which can affect quality of life (QOL). Objectives: This study aimed to assess the QOL in medical students with dysmenorrhea in Iran. Methods: This cross-sectional study included 298 female students between December 2021 and August 2022. The EQ-5D-3L questionnaire was used to assess the QOL of subjects. Also, age, weight, height, sleep hours per day, and exercise hours per week were evaluated. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) version 22. The chi-squared test and Fisher’s exact test were used for data analysis. Results: The mean age of students was 20.32 ± 3.19 years, and the prevalence of dysmenorrhea was 83.6% (n = 249). There was a significant difference in daily activity (P < 0.05) and exercise hours per week (P < 0.05) between the two groups. Pain and discomfort were remarkably higher in group with dysmenorrhea (P < 0.01). In addition, personal care was significantly reduced among subjects with dysmenorrhea (P < 0.05). Sleep hours per day, body mass index (BMI), age, mobility, and anxiety were similar between the two groups. Conclusions: According to our results, dysmenorrhea was significantly related to impaired QOL, considering some aspects such as daily activity.

Menstrual attitude and social cognitive stress influence autonomic nervous system in women with premenstrual syndrome

The autonomic nervous system (ANS) is activated by stress and is closely related to the female menstrual cycle. Women with premenstrual syndrome (PMS) have an imbalanced ANS response in their premenstrual period. However, no studies have explored the reasons for the differences in ANS response among women. In this study, we investigated how the female menstrual attitude and acute social stress influence the ANS response in women with PMS. First, 277 women [24.35 ± 2.1] were selected to measure the mediating role of women's menstrual attitude between PMS severity and perceived ANS response. Second, participants' (50 women [23.23 ± 1.25] with and 46 women [22.92 ± 2.00] without PMS) heart rate (HR) and HR variability (HRV; reflecting the functioning of ANS) under social stress were measured during various menstrual cycle phases. The results indicated that menstrual attitude (bothersome and predictable) had mediating effects between the degree of PMS and perceived ANS response; when undergoing a high cognitive load (e.g. mental-arithmetic) task, the ANS of the PMS group demonstrated hypo-arousal and delayed recovery in the late luteal phase; Therefore, menstrual attitude could influence female perceived ANS response, which may be a risk factor for PMS. When women with PMS experience high-strength cognitive pressure in the premenstrual period, their ANS showed hypo-arousal and delayed recovery, which may be another risk factor for PMS.

Relationship Between Lifestyle Habits and Health-Related Quality of Life of Recently Diagnosed Breast Cancer Patients: A Comparison Between Younger and Older Women in China

Objective: The aim of this study was to evaluate the relationship between lifestyle habits and health-related quality of life (HRQoL) among different ages who were initially diagnosed with breast cancer (within the first 2 weeks) and to determine the contribution of lifestyle habits factors on HRQoL.

Methods: Patients with breast cancer were recruited from 22 hospitals in 11 provinces or municipalities in northern and eastern China. The Functional Assessment of Cancer Therapy-Breast Cancer (FACT-B) was used to measure HRQoL. Chi-square test, ANOVA, and multivariable generalized linear models were conducted to identify the differences in HRQoL between two age groups (age <50 years and ≥50 years) and to evaluate the contribution of lifestyle habits factors on HRQoL of patients with breast cancer.

Results: About 1,199 eligible patients with breast cancer were used for analysis. Younger women (aged <50 years) appeared to show lower scores than older women (aged ≥50 years) in HRQoL subscales, including emotional well-being (p = 0.003), functional well-being (p = 0.006), breast cancer subscale (p = 0.038), and FACT-B Total scores (p = 0.028). Tea and alcohol consumption and being very satisfied with sleep and current life were the strongest predictors of higher HRQoL in younger group. Meanwhile, no coffee consumption, frequent participation in physical activities, high sleep satisfaction, and current life satisfaction were the key predictors of higher HRQoL in older women with breast cancer.

Conclusion: The relationship of the nine lifestyle habit items with HRQoL differed among younger and older women. The associated variable of low HRQoL can help clinicians take intervention early in order to improve the prognosis of patients with breast cancer.

[Secondary Data Analysis on the Factors Influencing Premenstrual Symptoms of Shift Work Nurses: Focused on the Sleep and Occupational Stress]

PURPOSE

This study aimed to examine premenstrual symptoms (PMS) of shift nurses and identify the association between PMS, sleep, and occupational stress.

METHODS

This study was conducted with a secondary data analysis that used data from the Shift Work Nurse's Health and Turnover study. The participants were 258 nurses who were working in shifts including night shifts. PMS, sleep patterns (sleep time and sleep time variability), sleep quality, and the occupational stress of each participant were measured using the Moos Menstrual Distress Questionnaire, a sleep diary, an actigraph, the Insomnia Severity Index, and the Korean Occupational Stress Scale, respectively. Data were analyzed using SPSS 23 and STATA 15.1 to obtain descriptive statistics, Pearson's correlation coefficients, multiple linear regression with generalized estimating equations (GEE) and Baron and Kenny's mediating analysis.

RESULTS

The average PMS score, average sleep time, average sleep time variability, average sleep quality score, and average occupational stress score of the participants was 53.95 ± 40.45, 7.52 ± 0.89 hours, 32.84 ± 8.43%, 12.34 ± 5.95, and 49.89 ± 8.98, respectively. A multiple linear regression analysis with GEE indicated that sleep time variability (B = 0.86, p = .001), and sleep quality (B = 2.36, p < .001) had negative effects on nurses' PMS. We also found that sleep quality had a complete mediating effect in the relationship between occupational stress and PMS.

CONCLUSION

These findings indicate that both sleep time variability and sleep quality are important factors associated with PMS among shift work nurses. To improve shift nurses' PMS status, strategies are urgently needed to decrease sleep time variability and increase sleep quality.

Development of an Assessment Tool of Menstrual-Cycle-Related Signs and Symptoms Based on Thai Traditional Medicine Principles for Evaluation of Women's Health

Background

Utilization of Thai traditional medicine (TTM) was considered in menstrual-cycle-related signs and symptoms (MCSs) to evaluate women's health. TTM clinicians diagnosed the MCSs by signs, symptoms, and associated factors of patients including a physical examination to find patterns of imbalance elements and the origin of the disorder to optimize treatment. Thus, the purpose of this study was to develop a new assessment tool, the menstrual-cycle-related signs and symptoms questionnaire (MCSQ) based on TTM principles for evaluation of women's menstrual health.

Methods

The items and components of the MCSQ were adjusted by TTM expert consensus using the Delphi technique. The content validity of the MCSQ was quantified by the content validity index (CVI). MCSQ were examined by construct validity and internal consistency reliability using exploratory factor analysis (EFA) and Cronbach's α coefficient, respectively.

Results

: All 19 experts (100%) responded to the questionnaires in the three rounds of the Delphi technique. The MCSQ showed high content validity of individual items (I-CVI = 0.83-1.00) and high overall content validity of the questionnaire (S-CVI/AVE = 0.98). Overall, 429 of 432 participants completed the questionnaire (99.31%). After factor analysis, the final MCSQ was divided into two sections, which consisted of 49 items. The first had 23 items focusing on the MCSs. And, the second had 14 items of personal and medical data including 12 items of associated factors. Cronbach's α coefficient of the final MCSQ was 0.87, and that of each component was between 0.32 and 0.82.

Conclusions

This study reports a new MCS questionnaire tool, which was developed from TTM knowledge to evaluate women's health. This questionnaire showed an acceptable level of validity and reliability. Thus, it is also expected to be useful in clinical practice and ongoing research on evaluation of women's health.

Premenstrual syndrome and premenstrual dysphoric disorders among Jordanian women

PURPOSE

The aim of this study was to investigate the frequency, associated factors, and management approaches of premenstrual dysphoric disorder (PMDD) and premenstrual syndrome (PMS) in Jordanian women.

DESIGN AND METHODS

Three hundred premenopausal women completed a self-administered questionnaire.

FINDINGS

Moderate-severe PMS was reported by 29% of women, while 14% had PMDD. Younger unmarried women had the more severe condition. Herbal remedies and no medication were the most common approaches used to manage PMS/PMDD.

IMPLICATIONS FOR NURSING PRACTICE

High rates of PMS and PMDD found in this study highlight the need to increase awareness to this condition among health providers in order to facilitate its identification, diagnosis, and management.

Development and psychometric validation of the Menstrual Health Instrument (MHI) for adolescents in Korea

The aims of the researchers were to develop and test initial psychometric properties of the Menstrual Health Instrument, a measure of menstrual health in adolescents that comprehensively evaluates menstrual health. Data were collected with a convenience sample of 230 Korean adolescent girls. As a result of exploratory factor analysis with the 29-item instrument, five factors were extracted: affective symptoms, somatic symptoms and school life, daily habits for menstrual health, menstrual cycle characteristics, and attitudes and perceptions on menstruation. The reliability and validity estimates indicate the Menstrual Health Instrument could be used for screening in school or community settings.

Factors associated with the severity of premenstrual syndrome among Iranian college students

AIM

Premenstrual syndrome (PMS) is characterized by physical, cognitive, and behavioral symptoms that occur cyclically, from several days to 2 weeks before menses, which resolve either quickly or during the early days of menstruation. The aim of this study was to determine the factors associated with the severity of PMS in Iranian college students.

METHODS

The cross-sectional study was performed among 298 college students (aged 18-35 years) with PMS, of whom, 271 college students completed the Iranian version of the Premenstrual Symptoms Screening Tool questionnaire to determine the severity of PMS. Factors associated with PMS severity were identified using linear regression analysis with a stepwise method.

RESULTS

Factors associated with severity of PMS were age (years), family income (low vs high income), marital status (unmarried vs married), and familial history of dysmenorrhea or PMS after adjustment for dysmenorrheal severity with β (95% confidence interval) of 0.31 (0.45-0.57), 11.6 (1.2-23.54), 3.2 (0.4-5.2), and 2.22 (0.04-4.4), respectively.

CONCLUSION

In this study, factors associated with severity of PMS were age, marital status, family income, and familial history of PMS. We observed that some outcomes were consistent with some previously reported results, which indicates the need for further studies.

Validation of the Brazilian Portuguese version of the Premenstrual Symptoms Screening Tool (PSST) and association of PSST scores with health-related quality of life

Objective:

To develop and validate a Brazilian Portuguese version of the Premenstrual Symptoms Screening Tool (PSST), a questionnaire used for the screening of premenstrual syndrome (PMS) and of the most severe form of PMS, premenstrual dysphoric disorder (PMDD). The PSST also rates the impact of premenstrual symptoms on daily activities.

Methods:

A consecutive sample of 801 women aged ≥ 18 years completed the study protocol. The internal consistency, test-retest reliability, and content validity of the Brazilian PSST were determined. The independent association of a positive screen for PMS or PMDD and quality of life determined by the World Health Organization Quality of Life instrument-Abbreviated version (WHOQOL-Bref) was also assessed.

Results:

Of 801 participants, 132 (16.5%) had a positive screening for PMDD. The Brazilian PSST had adequate internal consistency (Cronbach's alpha = 0.91) and test-retest reliability. The PSST also had adequate convergent/discriminant validity, without redundancy. Content validity ratio and content validity index were 0.61 and 0.94 respectively. Finally, a positive screen for PMS/PMDD was associated with worse WHOQOL-Bref scores.

Conclusions:

These findings suggest that PSST is a reliable and valid instrument to screen for PMS/PMDD in Brazilian women.

A prospective study of caffeine and coffee intake and premenstrual syndrome

BACKGROUND

Clinically significant premenstrual syndrome (PMS) affects 15-20% of premenopausal women, substantially reducing quality of life. Women with PMS often are counseled to minimize caffeine intake, although only limited evidence supports this recommendation.

OBJECTIVE

We evaluated the association between total caffeine, coffee, and tea intake and the development of PMS in a case-control study nested within the prospective Nurses' Health Study II.

DESIGN

All participants were free from PMS at baseline (1991). PMS cases reported a new clinician-made diagnosis of PMS on biennial questionnaires between 1993 and 2005, and then confirmed symptom timing and moderate-to-severe impact and severity of symptoms with the use of a retrospective questionnaire (n = 1234). Controls did not report PMS and confirmed experiencing no symptoms or few mild symptoms with limited personal impact (n = 2426). Caffeine, coffee, and tea intake was measured by food-frequency questionnaires every 4 y, and data on smoking, body weight, and other factors were updated every 2-4 y. Logistic regression was used to evaluate the associations of total caffeine intake and frequency of coffee and tea consumption with PMS.

RESULTS

After adjustment for age, smoking, and other factors, total caffeine intake was not associated with PMS. The OR comparing women with the highest (quintile median = 543 mg/d) to the lowest (quintile median = 18 mg/d) caffeine intake was 0.79 (95% CI: 0.61, 1.04; P-trend = 0.31). High caffeinated coffee intake also was not associated with risk of PMS or specific symptoms, including breast tenderness (OR for ≥4 cups/d compared with <1/mo: 0.73; 95% CI: 0.48, 1.12; P-trend = 0.44).

CONCLUSIONS

Our findings suggest that caffeine intake is not associated with PMS, and that current recommendations for women to reduce caffeine intake may not help prevent the development of PMS.

Prevalence of premenstrual syndrome and premenstrual dysphoric disorder among college students of Bhavnagar, Gujarat

BACKGROUND

Premenstrual dysphoric disorder (PMDD) is a severe form of premenstrual syndrome (PMS) characterized by mood changes, anxiety, and somatic symptoms experienced during the specific time of menstrual cycle. Prevalence data of PMS and PMDD is sparse among college girls in India.

AIMS

The aim of this study is to study the prevalence of PMS and PMDD among college students of Bhavnagar (Gujarat), its associated demographic and menstrual factors, to rank common symptoms and compare premenstrual symptom screening tool (PSST) with Structured Clinical Interview for DSM-IV-TR defined PMDD (SCID-PMDD) for sensitivity and specificity.

MATERIALS AND METHODS

A cross-sectional survey was done in five colleges of Bhavnagar. Of 529 subjects approached, 489 college girls were finally analyzed for sociodemographic data, menstrual history, and PSST. SCID-PMDD was applied among those who were positive on PSST and 20% of those who were negative. The data were analyzed using OpenEpi Version 2. Chi-square test was done for qualitative variables and analysis of variance for quantitative variables. Sensitivity, specificity, and predictive values were calculated for PSST.

RESULTS

The prevalence of PMS was 18.4%. Moderate to severe PMS was 14.7% and PMDD was 3.7% according to DSM IV-TR and 91% according to International Classification of Diseases, 10(th) edition criteria. The symptoms commonly reported were "fatigue/lack of energy," "decrease interest in work," and "anger/irritability." The most common functional impairment item was "school/work efficiency and productivity." PSST has 90.9% sensitivity, 57.01% specificity, and 97.01% predictive value of negative test.

CONCLUSION

Prevalence of PMS among college students is similar to other studies from Asia. PSST is a useful screening tool for PMS, and it should be confirmed by more specific tool as by SCID-PMDD. Routine screening with PSST can identify college girls who can improve with treatment.

Effect of Premenstrual Syndrome on Work-Related Quality of Life in Turkish Nurses

Background

Little is known about the effects of premenstrual syndrome (PMS) on work-related quality of life in nurses. We aimed to investigate the effect of PMS on work-related quality of life in Turkish nurses.

Methods

A total of 134 volunteer nurses were included in this cross-sectional study between January 2015 and March 2015. One hundred and thirty-four nurses completed a questionnaire regarding demographic data, the Premenstrual Syndrome Scale (PMSS), and the Work-Related Quality of Life Scale (WRQoL). The nurses were classified as having or not having premenstrual syndrome according to the PMSS.

Results

The average age was 29.5 ± 7.1 years and the prevalence of PMS was 38.1%. The total score of PMSS was significantly negatively correlated with the overall score (r = −0.341; p < 0.001) and all subscale scores of the WRQoL and ranged from −0.207 to −0.402 (p < 0.05 for all). All of the WRQoL subscale scores except stress at work (p = 0.179) in nurses with PMS were significantly lower than those of nurses without PMS (p < 0.05). The age (β = −0.258; p = 0.021) and PMSS total score (β = −0.314; p < 0.001) increment negatively; however, optimistic thinking (β = 0.228; p = 0.008) positively affected overall WRQoL score.

Conclusion

Nurses with PMS have decreased levels of work-related quality of life in their professional lives. Methods to help cope with cyclic premenstrual symptoms may be used, and as a result, productivity and work-related quality of life may increase.

Premenstrual syndrome in Turkish medical students and their quality of life

This study aimed to analyse the frequency and symptoms of premenstrual syndrome (PMS) and its effect on quality of life in medical students. Sociodemographic data, a symptom calendar for the following consecutive two menstrual periods and SF-36 quality of life questionnaire were collected. A total of 228 students joined the survey. The average age of the students was 20.77 ± 1.90. The frequency of PMS was 91.8%. The most frequent symptoms were abdominal bloating (89.5%), irritability (88.3%) and breast tenderness (82.6%). Quality of life scores ranged from 17.00 to 97.00 and were lowest in the severe PMS group. Alcohol consumption, stress events and fat rich diets increased the severity of PMS. Family history significantly affected the severity of PMS and quality of life scores. Premenstrual syndrome was found to be a frequent entity among medical students and seemed to affect quality of life in a moderate way.

The Iranian version of the Premenstrual Symptoms Screening Tool (PSST): a validation study

The objective of the current study was to translate and test psychometric properties of the Premenstrual Symptoms Screening Tool (PSST) in Iran. Using a standard "forward-backward" procedure, the English version of PSST was translated into Persian. A random sample of university students aged 18 years and over completed the questionnaire in Tehran, Iran. Psychometric properties of the Iranian version of PSST were assessed by performing reliability (internal consistency) and validity analyses [Content Validity Ratio (CVR) and Content Validity Index (CVI)]. In all, 925 female students took part in the study. Of these, 284 (30.7 %) had premenstrual syndrome (PMS) and 119 (12.9 %) had premenstrual dysphoric disorder (PMDD). Reliability of the PSST as measured by internal consistency was found to be satisfactory (Cronbach's alpha coefficient, 0.93). The content validity as assessed by CVR and CVI were desirable (0.7 and 0.8, respectively). The Iranian version of PSST seems to be a reliable and valid measure of detecting PMS and PMDD in Iranian young female populations.

Premenstrual syndrome and attitudes toward menstruation in a sample of nursing students

OBJECTIVE

The aim of this study was to evaluate baccalaureate nursing students' attitudes toward menstruation, and to analyze the frequency of premenstrual syndrome (PMS) symptoms, as well as the relationship between attitudes toward menstruation and PMS symptoms.

METHODS

This cross-sectional study was carried out between February 15 and March 10, 2009, in Ankara Turkey. The study participants were 250 undergraduate nursing student volunteers. Data were collected using a demographic questionnaire, the validated Turkish version of the Menstrual Attitude Questionnaire (MAQ), and the validated Turkish Premenstrual Syndrome (PMS) Scale. Obtained data were analyzed using SPSS version 15.0.

FINDINGS

The average age of participants was 19.89 ± 1.43. The MAQ's five subscales' mean scores ranged from 2.67 ± 0.58 to 3.37 ± 0.52, indicating natural to moderate attitudes toward menstruation. The mean PMS score was 114.86 ± 35.15, indicating moderate PMS symptoms. PMS symptoms were detected in 36.4% of the nursing students. Thirty one percent of the students reported having dysmenorrhoea during every menstrual cycle. Students who had PMS symptoms scored significantly higher on the debilitation subscale and scored significantly lower on the denial subscale of the MAQ (p < 0.05).

CONCLUSIONS

The findings of this research showed that menstruation was considered to be a natural event by most of the nursing students. In addition, dysmenorrhea was found to be the most common menstrual problem and the rate of PMS was found lower than that found in previous researches conducted in Turkey.

Prevalence of dysmenorrhea and its effect on quality of life among a group of female university students

The objective was to evaluate the prevalence of dysmenorrhea and determine its effect on health-related quality of life (HRQoL) among a group of female university students. This cross-sectional study was conducted between 15 March and 15 April 2009 at Dumlupinar University, Kutahya, Health High School, Western Turkey. The study group included 623 female students. The severity of dysmenorrhea was determined with a 10-point visual analog scale. The Short Form-36 (SF-36) form was used to determinate HRQoL. Chi-square test, Student's t test, and logistic regression and variance analyses (ANOVA) were used for statistical analyses. The average age of the study group was 20.8 +/- 1.8 years (range 17-30). Prevalence of dysmenorrhea was found to be 72.7% and was significantly higher in coffee consumers, females with menstrual bleeding duration > or =7 days, and those who had a positive family history of dysmenorrhea when compared to the others (P < 0.05, for each one). By multivariate analysis, coffee consumption (OR 2.084), menstrual bleeding duration > or =7 days (OR 1.590), and positive family history of dysmenorrhea (OR 3.043) were important risk factors for dysmenorrhea. Except for social functioning, role-emotional, and mental health domains, the SF-36 points received from the other domains were higher in females with dysmenorrhea (for each one P < 0.05). With the exception of the scores received from physical functioning and role-emotional domains, the scores received from the other domains of the SF-36 scale showed a decrease with increasing severity of dysmenorrhea (P < 0.05, for each one). Dysmenorrhea is a common health problem, having negative effects on the HRQoL among university female students.

A culturally sensitive study of premenstrual and menstrual symptoms among Chinese women

This is a two-part study of perimenstrual symptomatology in Chinese women. We developed and validated the Chinese Questionnaire of Perimenstrual Symptoms (CQ-PERI-MS), which was adapted from the Moos Menstrual Distress Questionnaire, and used this instrument to assess the prevalence and nature of perimenstrual symptoms among Chinese women in Hong Kong. The initial CQ-PERI-MS was first administered to a sample of 538 menstruating Chinese women in Hong Kong together with measures of anxiety, depression and neuroticism. Psychometric analyses rendered a 32-item CQ-PERI-MS which demonstrated good reliability, convergent and discriminant validity, and factorial validity. Four factors were yielded, namely, Dysphoria, Somatic distress, Cognitive problems and Arousal. The CQ-PERI-MS was then administered to a separate sample of 339 menstruating Chinese women in Hong Kong for further examination of validity as well as pattern of perimenstrual symptoms. It was found that perimenstrual symptoms were common, with 18.6% and 34.2% of the participants reporting 10 or more premenstrual and menstrual symptoms, respectively. Both premenstrual and menstrual distress were characterised by a combination of emotional and somatic symptoms. Contrary to previous preconceptions, perimenstrual symptoms are commonly experienced by Chinese women, with both overlapping and distinct features when compared with patterns in the West.
