Similarities and Differences of Mental Health in Women and Men: A Systematic Review of Findings in Three Large German Cohorts

Stability and predictors of somatic symptoms in men and women over 10 years: A real-world perspective from the prospective MONICA/KORA study

OBJECTIVE

To assess the stability of somatic symptoms in community-dwelling participants.

METHODS

The study included 2472 participants (1190 men, 1282 women; mean age 44.3 ± 10.9) from the prospective population-based MONICA-S3 cohort (1994/95) and the 10-year follow-up KORA-F3 cohort. Somatic symptoms were assessed by an adapted version of the Somatic Symptom Scale-8 (SSS-8a) with scores ranging from 0 to 24. Somatic symptom stability was assessed by weighted kappa values (κ). Generalized Estimating Equation models assessing symptom stability were adjusted for sociodemographic, lifestyle, clinical and psychosocial risk factors, as well as pre-existing medical conditions.

RESULTS

The mean (±SD) SSS-8a was lower in men (S3: 6.88 ± 3.87, F3: 6.60 ± 3.86) than women (S3: 8.43 ± 4.0, F3: 8.31 ± 4.2) at both time points. However, somatic symptoms remained moderately stable in both genders over 10 years (κ =0.42 in men and κ = 0.48 in women), with the largest stability observed in trouble sleeping for men (κ =0.41) and pain in the joints for women (κ =0.41). Pre-existing somatic symptoms were significantly associated with increasing symptoms at follow-up [men: β = 0.82 (SE 0.12), women: β = 0.85 (SE 0.12)], followed by age and psychosocial factors, whereas higher education and recent health care utilization were inversely associated with increasing symptoms. Although hypertension and obesity were associated with increasing somatic symptoms in men, pre-existing medical conditions were not associated with increasing somatic symptoms in men nor women.

CONCLUSIONS

The current findings indicate that somatic symptoms remain moderately stable in the general population during 10 years of follow-up, mainly driven by sociodemographic and psychosocial factors.

Changes in health behaviors and conditions during COVID-19 pandemic strict campus lockdown among Chinese university students

Objective

To explore how a stringent campus lockdown affects the physical activity (PA), sleep and mental health of Chinese university students living in student dormitories during the COVID-19 pandemic.

Methods

Data on PA, sleep and mental health were collected between 24 March and 4 April 2022 from 2084 university students (mean age = 22.4 years, 61.1% male students) via an online questionnaire distributed by the students’ advisers of each dormitory. The Chinese short version of the International Physical Activity Questionnaire (IPAQ-C), Athens Insomnia Scale (CAIS) and General Health Questionnaire 12-item (GHQ-12) were applied. The Mann–Whitney test and Kruskal-Wallis tests were used to evaluate the PA profile differences between genders, before and during the lockdown period and between students’ living environments. Chi-squared (χ2) or Fisher’s exact test was used to assess changes in health behaviors by gender and students’ living environment compared to before the lockdown. A mediation model was used to examine whether sleep disorder mediated the relationship between PA and mental health in different students’ living environments.

Results

Participants reported a significant decrease in weekly total PA levels (63.9%). Mean daily sedentary time increased by 21.4% and daily lying time increased by 10.7% compared to before lockdown. Among the participants, 21.2% had experienced insomnia, and 39.0% reported having high mental distress. Female students reported 10% higher rates of sleep disorders than male students (p < 0.001), and also experienced a higher incidence of mental disorders (p < 0.001). Students living with three roommates had a larger decrease in frequencies and durations of participation in light PA than other students (p < 0.001). PA was negatively associated with sleep and mental health, and sleep disorder was a mediating factor between PA and mental health in the students living with two and three roommates.

Conclusion

This study showed that strict lockdowns within university dormitories during the COVID-19 pandemic had a negative effect on the health of university students by changing their health behaviors, physical activity and sleep. Our findings indicate a need for strategies to promote an active lifestyle for students in space-limited dormitories in order to maintain health during a prolonged lockdown.

Lifestyle, Demographic and Socio-Economic Determinants of Mental Health Disorders of Employees in the European Countries

Ensuring the health and well-being of workers should be a top priority for employers and governments. The aim of the article is to evaluate and rank the importance of mental health determinants: lifestyle, demographic factors and socio-economic status. The research study is based on EHIS 2013-2015 data for a sample of N = 140,791 employees from 30 European countries. The results obtained using machine learning techniques such as gradient-boosted trees and SHAPley values show that the mental health of European employees is strongly determined by the BMI, age and social support from close people. The next vital features are alcohol consumption, an unmet need for health care and sports activity, followed by the affordability of medicine or treatment, income and occupation. The wide range of variables clearly indicates that there is an important role for governments to play in order to minimize the risk of mental disorders across various socio-economic groups. It is also a signal for businesses to help boost the mental health of their employees by creating holistic, mentally friendly working conditions, such as offering time-management training, implementing morning briefings, offering quiet areas, making employees feel valued, educating them about depression and burnout symptoms, and promoting a healthy lifestyle.

Food insecurity and symptoms of anxiety and depression disorder during the COVID- 19 pandemic: COVID-Inconfidentes, a population-based survey

This study aimed to investigate the association between adult food insecurity (FI) and symptoms of generalized anxiety disorder (GAD) and major depressive disorder (MDD) in two Brazilian cities during the coronavirus disease (COVID-19) pandemic. This study used data derived from a cross-sectional survey of 1693 adults. Interviews were conducted using an electronic questionnaire. The FI was measured using the Brazilian Food Insecurity Scale. The Generalized Anxiety Disorder-7 was used to measure the symptoms of GAD. The Patient Health Questionnaire-9 was used for MDD symptoms. The association between FI, GAD, and MDD symptoms was investigated using a Poisson regression model with robust variance to estimate the prevalence ratio and 95% confidence interval (95% CI). In regression models, a linear association between FI levels and outcomes was observed, with severe food insecurity having a 3.56 higher prevalence of GAD symptoms (95% CI: 2.23, 5.68) and a 3.03 higher prevalence of MDD (95% CI: 1.55, 5.90). In the stratified analyses, worse results were observed for females and males, individuals with non-white race/skin color, those without children, and those with lower monthly family income. In conclusion, the FI was associated with symptoms of GAD and MDD, and the sociodemographic characteristics interfered in this association. Therefore, we recommend the improvement of public health and social protection policies for food-insecure people.

Where Sex Meets Gender: How Sex and Gender Come Together to Cause Sex Differences in Mental Illness

Sex differences are prevalent in multiple mental disorders. Internalizing disorders are more commonly diagnosed in women, whereas externalizing and neurodevelopmental disorders are more often diagnosed in men. Significant sex/gender differences are reported in prevalence, symptom profile, age of onset, comorbidities, functional impairment, prognosis, as well as in responses to various treatments. In this conceptual article, we discuss theories and empirical studies of sex- and gender-related influences in mental health, by focusing on three examples: autism spectrum disorder (ASD), acknowledged as a disorder whose roots are mainly biological; eating disorders, whose origins are considered to be mainly psychosocial, and posttraumatic stress disorder (PTSD), an environmentally caused disorder with both psychosocial and biological underpinnings. We examine the ways in which sex differences emerge, from conception through adulthood. We also examine how gender dichotomies in exposures, expectations, role assumptions, and cultural traditions impact the expression of our three selected mental illnesses. We are especially interested in how sex-based influences and gender-based influences interact with one another to affect mental illness. We suggest that sex and gender are multi-faceted and complex phenomena that result in variations, not only between men and women, but also within each sex and gender through alterations in genes, hormone levels, self-perceptions, trauma experiences, and interpersonal relationships. Finally, we propose a conceptual diatheses-stress model, depicting how sex and gender come together to result in multiple sex/gender differences across mental disorders. In our model, we categorize diatheses into several categories: biological, intrapersonal, interpersonal, and environmental. These diatheses interact with exposure to stressors, ranging from relatively minor to traumatic, which allows for the sometimes bidirectional influences of acute and long-term stress responses. Sex and gender are discussed at every level of the model, thereby providing a framework for understanding and predicting sex/gender differences in expression, prevalence and treatment response of mental disorders. We encourage more research into this important field of study.

Does social support prevent suicidal ideation in women and men? Gender-sensitive analyses of an important protective factor within prospective community cohorts

BACKGROUND

Suicidal ideation and behavior constitute important public mental health issues. In this study, we examined whether social integration prevents suicidal ideation over time and whether gender modifies this association.

METHODS

Data from the Gutenberg Health Study (population-based representative community sample in midwest Germany) and the Study of Health in Pomerania (population-based cohort study in northeast Germany) were used. Participants reporting low social support were compared to those receiving middle or high social support. Within a longitudinal study design, we calculated multiple logistic regression models including interaction terms and relevant covariates to test whether gender modified the association of social support and suicidal ideation.

RESULTS

Suicidal ideation was present in 7.4% (N = 982) of the pooled cohorts' 13,290 participants. More women (8.6%, N = 565) than men (6.2%, N = 417) reported suicidal ideation. Middle or high social support was associated with a lower probability to report suicidal ideation five years later after controlling for sociodemographic factors, living situation, and cohort (OR = 0.42, 95%-CI = 0.34-0.52). Male gender was negatively related to suicidal ideation, but no statistically significant interaction of gender and social support was found (ratio of ORs = 1.00, 95%-CI = 0.73-1.35).

LIMITATIONS

The number of people reporting suicidal ideation in the SHIP study was small, especially for men. Suicidal ideation was measured using a single item.

CONCLUSIONS

Social support is an important protective factor in preventing suicidal ideation for both women and men. Future research should further clarify gender-specific effects of family variables in suicidal ideation and test similar predictive models of suicidal behavior.

Performance of Homebalance Test in an Assessment of Standing Balance in Elderly Adults

Balance control is a critical task of daily life, the ability to maintain upright posture becomes of particular concern during aging when the sensory and motor system becomes deteriorated. Falls contribute to the most deaths caused by injury within the aged population, and the mortality rate following a fall is drastically elevated. Longitudinal and reliable assessment of balance control abilities is a critical point in the prediction of increased risk of falling in an elderly population. The primary aim of the study was to evaluate the efficiency of the Homebalance test in the identification of persons being at higher risk of falling. 135 subjects (82 women and 53 men) with geriatric syndrome have been recruited and the Homebalance and the Tinetti Balance test were performed. Results of both tests strongly correlated proving the good performance of the Homebalance test. Standing balance declines with increasing body mass index in both genders. Analysis of fluctuations of the center of pressure (COP) revealed higher frequency and magnitude in mediolateral direction COP movements when compared women to men. A strong negative correlation has been found between Tinetti static balance score and the total length of the COP trajectory during the examination on Homebalance (r = -0.6, p<0.001). Although both methods revealed good performance in detecting balance impairment, Homebalance test possesses higher precision due to the continuous nature of COP-derived parameters. In conclusion, our data proved that the Homebalance test is capable to identify persons with impaired balance control and thus are at higher risk of falling.

The association of depression and all-cause mortality: Explanatory factors and the influence of gender

BACKGROUND

The association of depression with mortality and the significance of explanatory factors, in particularly gender, have remained an issue of debate. We therefore aimed to estimate the effect of depression on all-cause mortality, to examine potential explanatory factors and to assess effect modification by gender.

METHODS

We used Cox regression models to estimate the effect of depression on mortality based on data from the Gutenberg Health Study, which is a prospective cohort study of the adult population in the districts of Mainz and Mainz-Bingen, Germany. Baseline assessment was between 2007 and 2012. Effect modification by gender was measured on both additive and multiplicative scales.

RESULTS

Out of 14,653 participants, 7.7% were depressed according to Patient Health Questionnaire 9 (PHQ-9), and 1,059 (7.2%) died during a median follow-up of 10.7 years. Depression elevated the risk of mortality in men and women in age-adjusted models (HR: 1.41, 95%-CI: 1.03-1.92; resp. HR: 1.96, 95%-CI: 1.43-2.69). Adjustment for social status, physical health and lifestyle covariates attenuated the effect and in the fully-adjusted model the hazard ratio was 0.96 (95%-CI: 0.69-1.33) in men and 1.53 (95%-CI: 1.10-2.12) in women. For effect modification by gender, the measure on multiplicative interaction was 0.68 (95%-CI 0.44-1.07) and on additive interaction was RERI=-0.47 (95%-CI -1.24-0.30).

LIMITATIONS

The PHQ-9 is a single self-report measure of depression reflecting symptoms of the past two weeks, limiting a more detailed assessment of depression and course of symptoms, which likely affects the association with mortality.

CONCLUSIONS

Depression elevates mortality by multifactorial pathways, which should be taken into account in the biopsychosocially informed treatment of depression. Effect modification by gender was not statistically significant.

General and bladder-related quality of life: A focus on women living with spinal cord injury

OBJECTIVE

To compare bladder symptoms, and urinary and overall quality of life (QOL) among women and men after Spinal cord injury (SCI), and to describe specific aspects of QOL among women with SCI.

METHODS

We used data from a prospective, multi-center, and cross-sectional study that was carried out from May 2019 to September 2020. Clinical and demographic details were obtained and participants completed two patient reported outcomes: the neurogenic bladder symptoms score-short form (NBSS-SF, which measures bladder symptoms and QOL) and the SF-12 (which measures overall physical and mental health QOL).

RESULTS

Our cohort included 135 women and 210 men with SCI. Among the women, the median age was 50, and 40% had a cervical SCI. For general QOL, women with SCI had physical functioning scores similar to men, but lower mental health scores on the SF-12 (46.85 vs. 49.76, p = 0.01). Women had significantly worse overall NBSS (10.76 vs. 9.08, p < 0.001) and NBSS continence domain scores (4.71 vs. 3.66, p < 0.001) compared to men. There were significant differences between overall QOL measures, and bladder symptoms based on bladder management techniques among the women. NBSS-SF symptom scores were better among women who used overactive bladder medications compared to women who did not (8.43 vs. 11.9, p = 0.02) and NBSS-SF QOL domain scores were significantly better among women who underwent surgery and those that used overactive bladder medications.

CONCLUSIONS

Women have more bladder symptoms (specifically incontinence) compared to men. Symptom burden and overall QOL vary among women who use different bladder management techniques and treatments.

Depression Mediates the Association Between Childhood Emotional Abuse and the Onset of Type 2 Diabetes: Findings From German Multi-Cohort Prospective Studies

BACKGROUND

The dysregulation of glucose homeostasis via mental health stress is increasingly acknowledged, whereby depression independently increases the risk of the onset of type 2 diabetes by up to 60%. Contributing mental health factors starting in early life have further been considered, indicating that exposure to childhood emotional abuse is associated with both depression and an increased onset of type 2 diabetes in adulthood. However, the potential role of depression within the emotional abuse and type 2 diabetes link remains unknown.

METHODS

Data were derived from community-dwelling participants in southern and northeastern Germany who participated in the longitudinal KORA-F4 and SHIP-3 studies. Multivariable logistic regression analyses adjusted for lifestyle, somatic, and psychological risk factors were used to investigate the association between childhood emotional abuse, assessed retrospectively by the Childhood Trauma Screener, and newly diagnosed type 2 diabetes cases, which were confirmed using a standard oral glucose tolerance test. The mediating role of depressive symptoms between childhood emotional abuse and type 2 diabetes was assessed by the Patient Health Questionnaire-9 and calculated by using the Sobel test for mediation.

RESULTS

A total of 2,973 (53.2% women, 46.8% men) participants with a mean age of 49.7 were included in the analyses, of whom 5.9% (7.1% women, 4.5% men) reported emotional abuse in childhood. Participants exposed to childhood emotional abuse had a 1.70 (1.12-2.56; p = 0.02) times higher odds of depression in the fully adjusted model than unexposed participants. During the 6.5-year follow-up period, 104 (3.5%) participants developed type 2 diabetes. Participants who were exposed to childhood emotional abuse had a 2.56 (1.31-4.98, p = 0.005) times higher odds of developing type 2 diabetes than unexposed participants. This association was significantly mediated by the increased odds of depression in participants with childhood emotional abuse (Sobel Test, 1.84, p = 0.06; Goodman Test, 1.91, p = 0.05).

CONCLUSION

The current results indicate that the increased likelihood of type 2 diabetes onset in participants who were exposed to childhood emotional abuse is significantly attributed to increased depression in adulthood.

Mental Health and Wellbeing in Lithuanian Medical Students and Resident Doctors During COVID-19 Pandemic

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic has had a negative effect on mental health and subjective psychological wellbeing. One of the most affected population is medical students, reporting higher levels of depression, anxiety, sleep difficulties, and overall poorer wellbeing. However, the relationship between depression, anxiety, and sleep difficulties, and subjective psychological wellbeing has not been extensively researched in medical students in the context of COVID-19 pandemic. The aim of this study was to investigate the associations between depression, anxiety, and sleep quality, and subjective psychological wellbeing.

METHODS

In total, 524 medical students and resident doctors (78.6% female, mean age 24 ± 3 years old) participated in an online survey between December 2020 and February 2021. Participants completed the WHO-Five Wellbeing Index Questionnaire, the Pittsburgh Sleep Quality Index questionnaire, the Patient Health Questionnaire-9, and the Generalized Anxiety Disorder Assessment-7.

RESULTS

Multivariable logistic regression analysis showed that female participants' worse subjective psychological wellbeing was associated with sleep difficulties [odds ratio (OR) = 2.39, 95% CI = 1.37-4.18, p = 0.002], higher depression (OR = 6.13, 95% CI = 3.46-10.88, p < 0.001), and anxiety symptoms (OR = 2.95, 95% CI = 1.66-5.22, p < 0.001). In male participants, analysis revealed an association between worse subjective psychological wellbeing and higher depression scores (OR = 9.94, 95% CI = 3.29-30.03, p < 0.001).

CONCLUSION

Sex differences are an important factor to consider when evaluating subjective psychological wellbeing. Clinicians should be aware of significant contributors, such as sleep patterns anxiety, and depression, to subjective psychological wellbeing.

Body dysmorphic disorder and depression among male undergraduate students in a Malaysian University

INTRODUCTION

Body dysmorphic disorder (BDD) and depression have been reported to be both prevalent among young people worldwide, resulting in serious implications in their quality of life and social functioning. This is worrying especially in men where mental disorders are often overlooked and under-researched. This study aims to determine the proportion of male university students with symptoms suggestive of body dysmorphic disorder and depression, as well as their perception on their body image.

METHODS

In this cross-sectional study, 1,308 male students between the aged of 17-26 years in a private university in Malaysia via self-administered online questionnaire comprising the Patient Health Questionnaire (PHQ)-9, the Body Dysmorphic Disorder Questionnaire (BQQD) and the Body Self-Image Questionnaire (BSIQ), in addition to their sociodemographic parameters. Data analyses were performed with Mann Whitney test, chi square test and Fisher's exact test.

RESULTS

3.3 and 54.2% of the students had symptoms suggestive of BDD and depression respectively, with up to 9.02% of the students reporting having moderate to severe depression. There was a significant association between BDD symptoms and students staying alone, whilst depression was significantly associated with studying in the rural campus. Furthermore, a significant association was demonstrated between presence of BDD and depression symptoms. Most of the students were dissatisfied with their whole body, especially their height.

CONCLUSION

The proportion of BDD and depression symptoms among male students in our university is quite high. Universities and the public health sector should develop better support service targeting male university students.

Bidimensional structure and measurement equivalence of the Patient Health Questionnaire-9: sex-sensitive assessment of depressive symptoms in three representative German cohort studies

BACKGROUND

The Patient Health Questionnaire-9 (PHQ-9) has been proposed as a reliable and valid screening instrument for depressive symptoms with one latent factor. However, studies explicitly testing alternative model structures found support for a two-dimensional structure reflecting a somatic and a cognitive-affective dimension. We investigated the bidimensional structure of the PHQ-9, with a somatic (sleeping problems, fatigability, appetitive problems, and psychomotor retardation) and a cognitive-affective dimension (lack of interest, depressed mood, negative feelings about self, concentration problems, and suicidal ideation), and tested for sex- and regional-differences.

METHODS

We have included data from the GEnder-Sensitive Analyses of mental health trajectories and implications for prevention: A multi-cohort consortium (GESA). Privacy-preserving analyses to provide information on the overall population and cohort-specific information and analyses of variance to compare depressive, somatic and cognitive-affective symptoms between sexes and cohorts were executed in DataSHIELD. In order to determine the dimensionality and measurement invariance of the PHQ-9 we tested three models (1 factor, 2 correlated factors, and bifactor) via confirmatory analyses and performed multi-group confirmatory factor analysis.

RESULTS

Differences between sex and cohorts exist for PHQ-9 and for both of its dimensions. Women reported depressive symptoms in general as well as somatic and cognitive-affective symptoms more frequently. For all tested models an acceptable to excellent fit was found, consistently indicating a better model fit for the two-factor and bifactor model. Scalar measurement invariance was established between women and men, the three cohorts, and their interaction.

CONCLUSIONS

The two facets of depression should be taken into account when using PHQ-9, while data also render support to a general factor. Somatic and cognitive-affective symptoms assessed by the PHQ-9 can be considered equivalent across women and men and between different German populations from different regions.

The Mental Health of German Students During the COVID-19 Pandemic

Abstract. Theoretical background: The COVID-19 pandemic has changed the daily lives of students completely. Studies indicated that psychology students may be less stressed during the pandemic than other students. This study compares psychology students and students from other disciplines regarding their mental health, alcohol consumption, and partnerships after the third wave of the COVID-19 pandemic. Methods: The study sample consisted of n = 127 psychology students and n = 579 students from other disciplines at the TU Braunschweig in Germany who participated in an online survey in June / July of 2021. To analyze the differences between the psychology students and students from other disciplines after the third wave, we calculated t-tests, Chi²-tests, and U-tests separately for female and male students. Results: Significantly fewer female psychology students were above the cut-off values for clinically relevant depressive symptoms (31.5 %; p  < .001, Cramer’s  V = .32) and anxiety symptoms (22.2 %; p < .001, Cramer’s V = .27) than other female students (depressive symptoms: 66.1 %; anxiety symptoms: 41.9 %). The small sample of male psychology students showed similar tendencies. While female psychology students rated their general health and life satisfaction higher than other female students, male psychology students were less concerned about their professional future than their respective counterparts. No differences were found concerning alcohol consumption and partnerships. Conclusion: We found indications that psychology students, especially female students, are less psychologically distressed after the third wave than students from other disciplines. Better mental health knowledge could be an explanation for this.
