Prevalence of alcohol consumption and alcohol use disorders among outdoor drinkers in public open places in Nigeria

BACKGROUND

There is a rapid shift in the social context of drinking, with a large proportion of regular drinkers favouring outdoor-open space drinking, such as motor-parks, by the road sides, the majority of which are unlicensed premises for drinking.

METHOD

This study determined the prevalence and determinants of harmful or hazardous alcohol use and possible dependence, defined as a "likely alcohol use disorder" (AUD) in a community sample of 1119 patrons of open space drinking places in Ibadan, Nigeria, using the AUDIT. Scores of 8 and above signified a likely AUD. The associations between a likely AUD and demographic characteristics were sought using Chi square statistics and binary regression analysis was used to determine the effects of multiple confounding variables on a likely AUD using the SPSS version 20.0 software.

RESULTS

Of the entire population, the prevalence of likely AUD was 39.5%, and 44.4% out of the drinking population Multivariate analysis showed that Islamic religion was a negative predictor for likely AUD, OR = 0.13, 95% CI (0.06-0.26), while rural residence, OR = 1.84, 95% CI (1.34-2.53) and cigarette smoking OR = 1.81, 95% CI (1.37-2.40) were predictive of likely AUD.

CONCLUSION

Outdoor-open space drinkers are likely to have AUD compared with the general population. Open space drinking has a huge public health implication because of the associated health risks and injuries.

Assessment of the alcohol consumption among outdoor bar drinkers in Nigeria by qualitative methods

Background

There are indications that drinking in outdoor bars, such as at motor-parks, by the roadsides or street corners have become popular in Nigeria.

Method

Three sets of qualitative assessments were carried out from three outdoor bars, randomly selected from 22 of such in Ibadan, Nigeria. The main sources of data were by direct observation and focus group discussion (FGD), conducted by a non-probabilistic sample of outdoor bar drinkers, alcohol vendors and from community members. The qualitative assessments were recorded, followed by a thematic analysis of the contents of the qualitative assessments.

Results

Widespread use of alcohol was reported. Patrons of outdoor bars reported that their context of drinking was pleasurable to them. Use of local beverages usually called ‘sepe’ is increasing. The majority of them do not have adequate health information about the harmful consequences of alcohol. Alcohol and other substances of abuse were openly displayed, sold and consumed at the study sites. There were poor law provision and enforcement of laws prohibiting open display of alcohol and other substances.

Conclusion

A high proportion of social drinkers in outdoor bars require intervention for their drinking behaviour. This is important because they have little or no information about the health hazards associated with excessive drinking. Presentation of these findings should contribute to increased awareness and improved response from the policy makers.

A Critical Assessment of Bias in Survey Studies Using Location-Based Sampling to Recruit Patrons in Bars

Location-based sampling is a method to obtain samples of people within ecological contexts relevant to specific public health outcomes. Random selection increases generalizability; however, in some circumstances (such as surveying bar patrons), recruitment conditions increase risks of sample bias. We attempted to recruit representative samples of bars and patrons in six California cities, but low response rates precluded meaningful analysis. A systematic review of 24 similar studies revealed that none addressed the key shortcomings of our study. We recommend steps to improve studies that use location-based sampling: (i) purposively sample places of interest, (ii) use recruitment strategies appropriate to the environment, and (iii) provide full information on response rates at all levels of sampling.
