Background: Alcohol is a leading risk factor for road traffic injury in low- and middle-income countries, such as Tanzania. This research seeks to explore the drinking patterns, perceptions, and stigma of drink driving behavior of injury patients at Kilimanjaro Christian Medical Center in Moshi, Tanzania., Methods: This mixed methods study incorporated the Perceived Alcohol Stigma (PAS), an additive Likert scale, and the Alcohol Use Disorders Identification Test (AUDIT). Results are reported as medians with IQRs. Additionally, focus groups with injury patients, their families, and community members (n = 104) were conducted and analyzed in pairs using an inductive thematic content analysis approach., Results: Those who self-reported driving after ingesting 3 or more alcoholic drinks had a median AUDIT score (median = 11.0) significantly higher than those who denied drink driving (median = 5.5, p < 0.01). The PAS showed a high overall stigma against those who use alcohol but differed for drink drivers, drinkers, and abstainers (median = 20.8, 23.9, 34.9, p < 0.01). Thematic content analysis highlighted a 'disapproving of drink drivers', that 'problematic drinking is a drinking behavior which negatively affects others', and a 'passiveness toward drinking and drink driving'., Conclusions: Stigma against those who use alcohol is present in Tanzania. Perceived stigma is significantly lower among those who drink drive than those who do not. Overall, there appears to be a community-wide disapproval of drinking and driving, which is coupled with feeling unable to change this risky behavior., Competing Interests: Declaration of Competing Interest The authors declare that there are no competing interests related to this manuscript., (Copyright © 2020 Elsevier Inc.

Objective: The Kilimanjaro region has one of the highest rates of reported alcohol use per capita in Tanzania. Alcohol-related risky behaviors pose substantial threats to the health and well-being of alcohol users and the people around them. This study seeks to understand how alcohol-related risky behaviors co-occur with other risky behaviors., Method: Latent class analysis (LCA) was applied to examine alcohol-related risky behaviors. The optimal number of latent classes was confirmed by using model fit indices. Negative binomial models were used to test latent classes and their association with harmful and hazardous drinking and perceived alcohol stigma. With the model defined, we explored each class's drinking patterns and risky behavior patterns., Results: A total of 622 (60% male) of 841 participants were included in these analyses because they drank alcohol at least once in their lifetime. Three classes of risky behavior patterns were identified: Class 1, "Limited risk behaviors" (59.7%); Class 2, "Primarily foolish behaviors" (25.6%); and Class 3, "Pervasive risk behaviors" (13.1%). Class 3 had the most alcohol use quantity and frequency. No association between classes and alcohol stigma was found. Compared with males, females are less likely to be classified in Class 2 and 3., Conclusions: Three different classes of risky behaviors became apparent and were distinguished by gender, age, and personal alcohol use. Our findings suggest a potential role for personalized interventions based on latent classes specifically to reduce risk behaviors.
