Abstract
Background: Use of substances such as alcohol, khat leaves (Catha edulis) and tobacco has become the rising major public health and socio-economic problems worldwide. This study was aimed to assess alcohol use among undergraduate students of Jigjiga University in Ethiopia.
Methods: A cross sectional study design was used and the study population was students from selected departments. The sample size was calculated by use of single population proportion formula. Accordingly, the calculated sample size was 648 after multiplying by design effect of 1.5 and adding 10%for non-response rate. Descriptive statistics, binary and multivariable logistic regressions was employed. Adjusted Odds Ratios together with corresponding 95% confidence intervals was used to interpret the findings.
Result: This study found 164(27.3%) alcohol users from the total of 600 respondents who filled the questionnaire. The odds of drinking alcohol was higher among senior students; those at 3rd year with AOR=5 (95% CI=2.13, 10.25), those at 4th year with AOR=4.92(95% CI=1.98, 12.14), compared with their junior 2nd year students. Male sex (AOR=2.12 95% CI=1.89, 6. 69) and use of other drugs (11.55(3.28, 40.75) were also positively associated to the use of alcohol.

Introduction
Alcohol drinking has become one of the rising major public health and socio-economic problems worldwide [1] and it is one of the most important risks taking behavior among adolescents and young population in colleges and Universities [1]. Recent trends indicate that the use of alcohol has dramatically increased particularly in developing countries [1]. It is estimated that 9% of the global population aged 12 or older are classified with dependence on psychoactive substances such as alcohol [2] and it becomes a growing concern among students [3].
Studies indicate that substance use among Ethiopian adolescents is considerably rising [4]. Nowadays, alcohol is widely consumed among high school and college students in Ethiopia [4]. Of the young segment of the Ethiopian population, college and university students are the most at risk of using alcohol [4]and entering University often leads to new opportunities, independence from family control, self-decision making, and peer-pressures to use or abuse alcohol. The use of alcohol among adolescents can be harmful, leading to decreased academic performance, increased risk of contracting HIV and other sexually transmitted diseases, or other psychiatric disorders such as lethargy, hopelessness and insomnia [2].
The six month prevalence rate of alcohol consumption was seventy percent and 28 percent were identified as regular users [5]. There is a strong link between khat chewing and excessive alcohol consumption, and it is believed to be one of the factors associated with unprotected risky sexual behavior, predisposing the youth for HIV infection and transmission [6]. The passage from high school to college is commonly marked by an increment in frequency of opportunities for peer interaction and in importance of the role of peer norms. According to a study conducted in United States of America 60% of individuals within the 21-25 age groups have reported alcohol consumption 30 days prior to the study accordingly, the current study aimed to determine the level of alcohol consumption in the study area [7].
Methods and Materials
Study Setting: This study was conducted in Jigjiga University located in Ethiopia Somali region. The University was established in 2007 and currently having 9 colleges with 14, 640 undergraduate students. Jigjiga is the capital city of the region which is at about 630km to the east of Addis Ababa.
Study design and population: Descriptive cross-sectional design was applied in this study. Randomly selected under graduate students of Jigjiga University was recruited during 2013/2014 academic session.
Sample Size Determination and Sampling Procedure: The required sample size was calculated by the single population proportion formula with the assumption of 4% margin of error (d), 95% confidence level (zα/2 =1.96) and 22% proportion of alcohol consumption taken from study conducted among medical students of Addis Ababa University [8].
Using a design effect of 1.5, the calculated sample size with 10% contingency for non-response was 648. A multi stage sampling procedure was applied to select sample of undergraduate students in the University. Initially we stratified the students by their college and three colleges namely college of Medicine and Health sciences, college of social sciences, and college of engineering and technology were randomly selected. The selected colleges were further stratified to departments and departments were selected by simple random sampling. The calculated sample size was proportionally allocated to each department based on the number of their students.
Data Collection Procedure: Self-administered structured questionnaire was used. Data collection was supervised by individuals with previous similar exposure and training was given by the principal investigators on how to create conducive environment for the respondents during data collection and to ensure confidentiality to improve the quality of the data.
Data Analysis: Data were entered using epi data version 3.1 and exported to Statistical Package for Social Science (SPSS) version 16 for further analysis. Following the cleaning, data were exported to SPSS version 16 for analysis. Data analyses were done through Univariate analysis to see the frequencies of the categories under each variable and the corresponding percentage for each category. Bivariable analysis also done to reveal association between the dependent variable (alcohol use) and independent variables like socio-demographic variables and lastly logistic regression was conducted to see the independent effect of the selected independent variables on the status of alcohol use using odds ratio.
Ethical Considerations: The study was reviewed and approved by the Jigjiga University-Directorate of Research and Community Service (JJU-DRCS) and all college deans and department heads were informed about this study. Participation of the students in this study was voluntarily and written consent was obtained from each participant before data collection. Students were informed that questionnaires are anonymous and confidential. Names of the students were not recorded anywhere on the questionnaire and measures taken to ensure the respect, dignity and freedom of each student participated in the study.
Results and Discussion
Background Characteristics of the Respondents
A total of 648 questionnaires were distributed and 600 of them were appropriately filled with the response rate of 92.6%. Data were collected from 2nd and above year students (we assumed that 1st year students may have different background since they join the University recently) of three colleges namely college of Medicine and Health sciences, college of social sciences, and college of engineering and technology which were randomly selected from eight colleges under the University. As it was shown in the table below, from the total of 600 study participants 281 (46.8%) were 2nd year, 176(29.3) were 3rd year, 143(23.8) 4th year and above, (411 (68.5) were in the age range of 22-25 years, 396 (66%) were male students. Majority of them were Muslim, 325 (54.2%), and 533 (88.8%) of them were single (Table 1).
Issues Related to Alcohol Drinking
As it was summarized below in table 2, 164 (27.3%) of the students have experienced alcohol drinking in their lifetime while 110 (18.3%) of them were current drinkers. Among the students who drink 60 (36.6%) of them started drinking at the age range of 16-20 years while about 10% of them responded that they were engaged in drinking after 20 years of age and about half of them responded they started alcohol drinking during the first 10 years of their life (Table 2).
Factors Associated to Drinking Alcohol among Jigjiga University Students
In our study among the independent variables, being year 3, and 4 and above year of study, age 22-25, being male sex, having drunker friend, being smoker, chat chewer and having history of drug use are significantly associated to the dependent variable look at Table 3. Accordingly, the odds of drinking alcohol was higher in year 3& 4 and above students compared with those at 2nd year students, (COR= 20.20; 95% CI: (11.30,36.20)] & [COR=2.48 ; 95%CI (1.58, 3.90)]. The odds of drinking alcohol was also higher among students with 22-25 compared to those with ager 18-21, [COR=5.18; 95% CI: (1.61, 16.67)], and the likelihood of drinking alcohol was higher among male students, [COR=2.82; 95% CI: (1.83, 4.36)]. Students with drinker friends were at higher risk of drinking alcohol COR=5.86; 95% CI: (3.89, 8.81)] when compared with those who don't have drinker friend.
*Significant at P< 0.05
As witnessed in Table 3 below, those students who ever chew chat were with higher odds of drinking alcohol COR=3.23; 95% CI: (2.22, 4.70)] when compared with those never chew chat. Those students who ever smoke cigarette were more likely to drink alcohol COR=4.212; 95% CI: (2.63,6.74)] comparing with non smokers .Being drug user was risk factor for alcoholism as those use drug were at higher risk for drinking alcohol COR=4.340;95% CI: (2.640,7.134)].
Discussion
In this study, we found the prevalence of ever drinking alcohol to be 27.3% and the prevalence of current drinking alcohol was 18.3%. Current prevalence is higher than the result of studies conducted among adolescent in Iran (15.1%) [9], among Debra Markos poly technique students (13.4%) [10], among Adigirat University students (8.7%) [11], among University students in Sudan (2.7%) [12] the possible reasons for the difference could be geographical locations, difference in times of study and availability of alcohol factory at near distance. The finding of this study was slightly lower than finding of a study conducted in Bishoftu (Ethiopia) (22.8%) [13], Italy (42.2%) [14], South Africa (70%) [15], Kenya (51.9%) [16], Ginnir town, (31.2%) [17], Woreta town (Ethiopia) (40.9%) [18], Dilla University (Ethiopia) (64.7%). This difference may be contributed by the difference in the study areas, availability of the source in the area and the attitude of the local community toward alcohol drinking and the timing of the study
The possible reasons for the difference could be cold weather conditions (in the case of Ginnir, Woreta), proximity to the capital city and time difference. This study showed that there was a positive relationship between alcohol drinking and students year of study. Accordingly, the odds of drinking alcohol was 3.7 times higher among students on their 3rd year of study compared with their juniors, (AOR=3.7(95% CI=2.40, 16), and this association became stronger when we compare participants in year four and above with those at 2nd year, (AOR=4.92(95% CI=1.98, 12.14).This study also revealed that being male is positively associated to drinking alcohol; the odds of drinking alcohol was about 2 times higher among male students compared with female students, AOR=2.12 95% CI=1.89,6. 69).
The finding of this study also revealed that having drinker friend, ever chew chat, ever smoke cigarette, and ever tried any drug were significantly associated with drinking alcohol, AOR=33.25 95 % CI=11),100, OR=2.78, 95% CI=1.15,6.83), AOR=4.45, 95% CI=1.04,19.08), 11.55(3.28,40.75), respectively. This positive relationship agrees with the finding of similar study conducted in Ethiopia among Addis Ababa University medical students in which male sex were significantly associated with alcohol drinking (AOR=2.14, 95% CI=1.22,3.76). The finding of our current study also comparable with the finding of the study which was conducted among AAU medical students in which those students having a drunker friend, having a friend who smokes, and having friend who chew chat, AOR=2.47, 3.89, and 15.11 respectively.
Conclusion
The prevalence of alcohol use among undergraduate students of Jigjiga University is significantly high, students' year of study, male sex, having a friend who use the substance especially alcohol, and using one substance were predisposing factors to alcohol use. It is therefore recommended that University top management should strengthen its collaboration with city municipality to move far drinking houses from the compound. There should be a regular awareness creation program for all students regarding to the health, economical, academicals and social burdens of being a drinker. It will be good to have a recreation centre within the compound of the university to minimize students' movement out of the campus. Researchers may also plan to do a triangulated study to investigate the root causes in detail.
