Substance Use Among People Seeking Health Care Services in Primary Health Care Settings in Coastal Karnataka

Background: Patients with substance use disorders are common in general medical practice and are a major risk factor for several non-communicable diseases. Appropriate screening is a vital step for providing brief interventions which can provide a good opportunity to tackle this crisis and in achieving target 3.5 of the sustainable development goal which includes strengthening the prevention and treatment of substance abuse. Objectives: To study the magnitude of substance use and factors associated with it among people seeking health care services at primary care settings. Methods: The cross-sectional study recruited people seeking services at primary care settings to screen for substance users (SU) and determine the associated factors. The data was collected using a pretested semi-structured questionnaire including socio-demographic characteristics, health status and the Alcohol, Smoking and Substance Involvement Screening Test tool. Results: The study showed that 43.4% of the participants were SU. The current use of smokeless tobacco was higher compared to tobacco smoking (21.3% and 4.7%). The multivariate logistic regression showed that advancing age (AOR: 2.61 and 95% CI of 1.01–6.79), male gender (AOR: 705 and 95% CI of 4.25–11.70), primary and middle school (AOR: 3.24 and 95% CI of 1.52–6.92) literacy status, unemployed (AOR: 0.49 and 95% CI of 0.25–0.95), religion and other backward caste (AOR: 2.42 and 95% CI of 1.37–4.30) were significant correlates of SU. Conclusion: Substance use was reported by two-fifths of the participants seeking services at primary care centres in our study and stresses the need for incorporating brief interventions to prevent higher degrees of dependence and its complications.
