Summary
Comorbid mental illnesses, including substance misuse, are increasingly prevalent in urban areas. Higher comorbidity numbers correlate with greater functional impairment, highlighting the need for integrated care.
Area of Science:
- Psychiatry
- Epidemiology
- Public Health
Background:
- Comorbidities among mental illnesses and substance misuse are under-documented in urban settings.
- Understanding these patterns is crucial for effective community mental healthcare.
Purpose of the Study:
- To examine the prevalence, diagnostic patterns, risk factors, and functioning associated with comorbid mental illness in an urban population.
- To investigate changes in comorbidity prevalence and patterns between 2010 and 2016.
Main Methods:
- Utilized data from the Singapore Mental Health Study (SMHS) 2010 (n=6616) and 2016 (n=6126).
- Employed logistic regression to identify associations between socio-demographics, clinical characteristics, comorbidity patterns, and functioning impairment.
Main Results:
- The prevalence of comorbid mental illnesses increased between 2010 and 2016.
- Major depressive disorder (MDD) with obsessive-compulsive disorder (OCD) and MDD with alcohol-related disorder (ARD) were common comorbidities.
- Increased number of comorbidities was linked to higher odds of functioning impairment in 2016.
Conclusions:
- The rising prevalence of comorbid mental illnesses necessitates early diagnosis and integrated disease management.
- Specific population subgroups are at higher risk for comorbid mental illnesses.
- Findings underscore the importance of addressing complex mental health needs in urban communities.

01:29Psychological and Sociocultural Causes of Schizophrenia
397
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

01:18Factors Affecting Illness
4.9K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:

Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

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...
