Environmental, Health and Sociodemographic Determinants Related to Common Mental Disorders in Adults: A Spanish Country-Wide Population-Based Study (2006-2017)

Prevalence of common mental disorders in southern Brazilian women: a comparison of two population-based studies (2003 vs. 2015)

PURPOSE

To investigate the prevalence and associated factors of common mental disorders (CMD) in women, and comparing them in two periods, 2003 and 2015.

METHODS

A comparative study was conducted between two surveys with representative samples of women aged 20-60 years residing in southern Brazil. The final sample included 988 and 987 women from the 2003 and 2015 surveys, respectively. The presence of CMD was assessed using the Self-Reporting Questionnaire (SRQ-20 ≥ 8) in both surveys. Poisson regression analysis was used to evaluate the associations between the outcome (CMD) and variables of interest.

RESULTS

The mean age of the participants was 38.5 ± 11.1 years (2003) and 40.3 ± 11.4 years (2015). In 2003, the prevalence of CMD was 33.4% (95%CI: 30.5-36.3) and in 2015, it was 33.7% (95%CI: 30.8-36.7). Over 12 years, no significant differences were observed in the prevalence of CMD, except for a reduction in the prevalence in women of color and physically active. After adjusting, the prevalence ratios of CMD in 2003 and 2015 remained associated with low family income, a higher number of pregnancies, and tobacco use.

CONCLUSIONS

This study showed a trend toward stability in the high prevalence of CMD among women.

Prevalence and trends of common mental disorders from 2007-2009 to 2019-2022: results from the Netherlands Mental Health Survey and Incidence Studies (NEMESIS), including comparison of prevalence rates before vs. during the COVID-19 pandemic

Up-to-date information on the prevalence and trends of common mental disorders is relevant to health care policy and planning, owing to the high burden associated with these disorders. In the first wave of the third Netherlands Mental Health Survey and Incidence Study (NEMESIS-3), a nationally representative sample was interviewed face-to-face from November 2019 to March 2022 (6,194 subjects; 1,576 interviewed before and 4,618 during the COVID-19 pandemic; age range: 18-75 years). A slightly modified version of the Composite International Diagnostic Interview 3.0 was used to assess DSM-IV and DSM-5 diagnoses. Trends in 12-month prevalence rates of DSM-IV mental disorders were examined by comparing these rates between NEMESIS-3 and NEMESIS-2 (6,646 subjects; age range: 18-64 years; interviewed from November 2007 to July 2009). Lifetime DSM-5 prevalence estimates in NEMESIS-3 were 28.6% for anxiety disorders, 27.6% for mood disorders, 16.7% for substance use disorders, and 3.6% for attention-deficit/hyperactivity disorder. Over the last 12 months, prevalence rates were 15.2%, 9.8%, 7.1%, and 3.2%, respectively. No differences in 12-month prevalence rates before vs. during the COVID-19 pandemic were found (26.7% pre-pandemic vs. 25.7% during the pandemic), even after controlling for differences in socio-demographic characteristics of the respondents interviewed in these two periods. This was the case for all four disorder categories. From 2007-2009 to 2019-2022, the 12-month prevalence rate of any DSM-IV disorder significantly increased from 17.4% to 26.1%. A stronger increase in prevalence was found for students, younger adults (18-34 years) and city dwellers. These data suggest that the prevalence of mental disorders has increased in the past decade, but this is not explained by the COVID-19 pandemic. The already high mental disorder risk of young adults has particularly further increased in recent years.

Gender Differences in the Prevalence of Mental Health, Psychological Distress and Psychotropic Medication Consumption in Spain: A Nationwide Population-Based Study

BACKGROUND

To assess gender differences in the prevalence of self-reported mental disorders, psychological distress and psychotropic drug consumption, and to identify sociodemographic and health-related variables associated with these conditions in the male and female population (aged ≥ 18 years).

METHODS

A cross-sectional study was carried on 22,141 subjects aged 18 and over, using data from the Spanish National Health Interview Survey 2017.

RESULTS

We found an overall prevalence of mental disorders, psychological distress and psychotropic drug consumption of 13.8%, 18.3% and 13.9%, respectively. After multivariable adjustment, women showed significantly increased probabilities of 1.74-fold for mental disorders, 1.26-fold for psychological distress and 1.26-fold for psychotropic drug consumption compared to men. Variables such as gender, age, nationality, marital status, educational level, self-rated health, the presence of different chronic disorders, alcohol consumption and smoking habit were independently associated with mental disorders, psychological distress and psychotropic drug consumption. Several variables showed a differential effect on mental health status and psychotropic drug consumption according to gender.

CONCLUSIONS

Women suffer from mental disorders, experience psychological distress and consume psychotropic drugs significantly more than men in Spain. Possible explanations for these results may be related to differences in emotional processing, willingness to report diseases and even intrinsic biological traits. Screening for mental health status and psychotropic drug consumption should be considered, particularly in Spanish women, younger adults and individuals who are not married, are obese, have poor self-rated health, suffer from chronic diseases or have a smoking habit.
