Psychiatric morbidity and substance use in migrant workers: A population based study

Area of Science:

• Public Health
• Mental Health Research
• Sociology

Background:

• Migrant populations exhibit higher rates of mental health challenges and substance abuse compared to the general population.
• Understanding these disparities is crucial for targeted public health interventions.

Purpose of the Study:

• To determine the prevalence and patterns of mental health issues and substance use among migrant workers.
• To investigate the association between reverse migration and these health concerns.

Main Methods:

• A study was conducted in Northern India involving 275 reverse migrants and 276 undisplaced individuals.
• Participants completed socio-demographic questionnaires, the Patient Health Questionnaire (PHQ-9) for mental health, and substance abuse screening tools.
• Data collection adhered to social distancing and mask-wearing protocols.

Main Results:

• Substance use (alcohol, tobacco, cannabis) was prevalent, with 44.4% of reverse migrants reporting ever use.
• 19.3% of reverse migrants met criteria for at least one mental health diagnosis on the PHQ-9, compared to 7.6% of undisplaced individuals.
• The prevalence of other depressive disorders was significantly higher in reverse migrants (17.1%) than undisplaced individuals (4.0%).

Conclusions:

• Mental health issues and substance abuse are significantly more prevalent in the migrant population.
• Reverse migration is associated with a higher incidence of mental health diagnoses, particularly depressive disorders, and substance use.
