Abstract
OBJECTIVE: The main objective of this study was to establish the blood alcohol concentrations (BACs) of bar patrons relative to the legal (BAC) limit for Ghana and the international guideline on alcohol consumption. METHOD: A cross-sectional study design and a convenience sampling technique were used to collect data at selected bars in 2 cities, namely; Bolgatanga and Wa, in northern Ghana. A breathalyzer was used to measure the breath alcohol concentrations of participants exiting bars and face-to-face questionnaires were administered to participants to capture their accident histories, alcohol consumption patterns, and modes of transport they usually use to travel to their next destination after alcohol consumption. RESULTS: The mean BAC of bar patrons was 0.143 ± 0.096% (95% confidence interval, 0.127 to 0.160%). The mean BAC of males (0.156%) was significantly higher than the mean BAC of females (0.103%; p = 0.004). Sixty-two percent of participants were exiting the bars with BACs of more than the legal BAC limit and 44% of this proportion was at 0.150% or more. Fifty-one percent of participants indicated that they usually consume a mixture of alcoholic beverages consisting of homemade and factory-made drinks. Fifty-seven percent of participants who usually consume a mixture of drinks had BACs of 0.150% or above. Only 22% of females and 6% of males consume alcohol within their respective recommended low risk of 1 to 2 units and 1 to 4 units, respectively. A vast majority of participants (96%) reported that they usually engage in risky behaviors such as riding, walking, or driving to their next destination after consuming alcohol. CONCLUSION: Motorists were more likely to exit the bars with very high BACs. It is recommended that police should enforce the BAC law. In addition, in order to prevent harmful use of alcohol, the introduction of an alcohol consumption guideline in Ghana is recommended. Because alcohol consumption is increasing currently with motorization, it is also necessary to educate alcohol users about the number of drinks required to stay below the legal limit if they are motorists as well as other road users or to prevent long-term illnesses associated with excessive alcohol use.
