The impact and patterns of hazardous drinking amongst male industrial workers in Goa, India

Introduction
The aim of this study was to describe the impact and patterns of drinking in hazardous drinkers in a male industrial worker population in India.

Methods
A case-control design was used, and 234 subjects (75 hazardous drinkers, 78 casual drinkers and 81 abstinent workers) were randomly selected from a population of male workers who had participated in a survey of drinking behaviour. The definition of these categories was based on the scores of subjects on the Alcohol Use Disorders Identification Test (AUDIT). Subjects were interviewed with a semi-structured social and health impact questionnaire, Revised Clinical Interview Schedule (CISR) and Brief Disability Questionnaire (BDQ). A total of 184 spouses of consenting workers were also interviewed with a semi-structured interview, the CISR, BDQ and AUDIT.A sub-group of 55 hazardous drinkers participated in a descriptive study of patterns of drinking, recording drinking behaviour using a daily drink diary over a 1-month period.

Results
Hazardous drinkers have significantly poorer physical and mental health and show trends for adverse social outcomes such as violence. Casual drinkers, on the other hand, were no different from abstinent subjects on any of the key outcomes. As compared to casual drinkers, hazardous drinkers tend to drink alone, in bars, and prefer noncommercial alcoholic beverages which are cheaper and have high alcohol concentration.

Discussion
Hazardous drinking has a significant adverse impact on drinkers and their families. Hazardous drinkers display unique drinking patterns suggesting the role of stigma and preference for higher alcohol-containing, but cheaper, drinks available in India.
