Summary
Common mental disorders decreased in urban São Paulo women aged 20-59 between 2003 and 2015. No significant changes were observed in men or older women during this period.
Area of Science:
- Public Health
- Epidemiology
- Mental Health Research
Background:
- Common mental disorders (CMDs) represent a significant public health concern globally.
- Understanding the temporal trends of CMDs is crucial for effective health policy and resource allocation.
- Previous research indicates varying prevalence rates of CMDs across different demographics and geographic locations.
Purpose of the Study:
- To investigate the temporal evolution of common mental disorders (CMDs) in adults residing in São Paulo city.
- To analyze trends in CMD prevalence from 2003 to 2015.
- To identify demographic variations in the temporal changes of CMDs.
Main Methods:
- Utilized population-based serial cross-sectional panel studies from the São Paulo City Health Survey (2003, 2008, 2015).
- Assessed CMDs using the Self-Reporting Questionnaire-20 (SRQ-20).
- Employed Poisson regression to calculate prevalence ratios (PR) and 95% confidence intervals (95%CI) for trend analysis.
Main Results:
- A total of 1,565 (2003), 2,019 (2008), and 3,169 (2015) participants were included.
- Adjusted analysis revealed a significant reduction in CMD prevalence among females aged 20-59 years between 2003 and 2015 (PR 0.68; 95%CI 0.56-0.84).
- No significant temporal variations in CMD prevalence were observed for males aged 20-59, females aged 60+, or males aged 60+.
Conclusions:
- The prevalence of common mental disorders has shown a declining trend among adult women (20-59 years) in urban São Paulo.
- These findings highlight a potential gender-specific temporal pattern in CMDs within this urban population.
- Further research is warranted to explore the underlying factors contributing to these observed trends and to inform targeted mental health interventions.

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

The Diagnostic and Statistical Manual of Mental Disorders (DSM) serves as the primary classification system for mental health disorders, providing standardized diagnostic criteria for clinicians and researchers. First published by the American Psychiatric Association (APA) in 1952, the DSM has undergone several revisions to reflect evolving psychiatric understanding. The fifth edition, DSM-5, released in 2013, introduced key updates that expanded diagnostic categories and modified diagnostic...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

01:08Prevalence and Incidence
265
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

01:29Theoretical Approaches to Psychological Disorder
56
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...
