Prevalence and associated factors of Khat chewing among people with HIV/AIDS at rural health centers of Ethiopia: a cross-sectional study

Objective: Khat, sometimes called “Qat” or “Chat” is fresh leaves a plant commonly chewed for its psycho-stimulant and euphorigenic effects of the brain. Although the adverse and complicated conspectuses of long term Khat use are evidenced, it is a commonly chewed in Ethiopia. Its burden and associated factors is not well addressed among HIV/AIDS in Ethiopia. This addressed this missed opportunity by assessing the frequency, pattern and associated factors of current Khat use among people with HIV/AIDS in Ethiopia. A systematic random sampling was used to select the study participants. Binary logistic regression was commutated to identify factors associated with Khat use. Results: About 30.1% and 24.7% of people with HIV/AIDS had lifetime and current khat use southern Ethiopia. Male sex {OR=2.46 95% CI(1.28, 4.73)}, rural residency { OR=2.4695%: CI(1.28, 10.14)}alcohol drinking {OR=1.84:95% CI(1.00, 3.37)} and frequency of schedule {OR=5.2595%CI(2.33, 11.85)} had a statistically significant association with current Khat use. This alarms a need for designing appropriate preventive and intervention programs for people living with HIV.

However, it is not well investigated among HIV-positive in Ethiopia. Therefore, this study was aimed to fill this gap by assessing the frequency, pattern and associated factors of Khat use among people with HIV/AIDS.

Study design and setting
This institutional-based cross-sectional study was conducted among people with HIV/AIDS attending at rural health centers from April 1 st to May 1 st , 2017. Gedeo one of the zones found in South Nation, Nationality and Peoples' Regional States of Ethiopia and its zonal city is Dilla. Dilla is located at359 km far from Addis Ababa (the capital city of Ethiopia).

Sample size determination and sampling procedure
For the sample size estimation, single population proportion formula with assumptions of; 95% CI, P=23% (prevalence of Khat use from Jimma hospital) [19] and a 5% margin of error was used for sample size. We used a 10% non-response rate and the total sample size was 300. After calculating the total number of people with HIV/AIDS in ART clinics of rural health centers, systematic random sampling technique was used based on the proportion of numbers of patients attending at each health center. We used an interval (K) calculated by dividing the total number of eligible participants to the proportionally allocated number of samples to each site.

Data collection instruments and procedures
Five trained nurses and two supervisors were participated in the data collection. We used an interviewer-administered questionnaire composed socio-demographic characteristics, Oslo-3 social support scale, Alcohol Use Disorders Identification Test (AUDIT), HIV/ AIDSrelated clinical factors, and questions used to assess the pattern and frequencies of Khat use. The Amharic and Gedeu'fa (the commonly spoken languages in the study area) versions of the questionnaire was use a pre-test was done among 17 (5%) patients attending ART clinics at Chuko health center. Individuals with age at least 18 years old and above and having ART follow-up visit were included in the study.

Operational definitions
Lifetime Khat use: Participants were considered as positive for life time khat use if he/she answered "Yes" to the question 'Have you ever used khat?' Follow up question related to the pattern, frequency and reasons for the initiation of khat chewing were also collected.

Current Khat use:
Participants were asked about their Khat use within the last one month even once. If they answer "YES" we considered as a current Khat user, and otherwise not. This study used some methodology parts from a previously published work [23,25] Data processing and analysis The field questionnaires were manually checked for its completeness and consistency.
The, the data were entered to SPSS version 20(soft ware) for analysis and binary logistic regression was computed. Descriptive statistics were used to quantify the frequency, pattern and the reasons for the initiation of chewing. Results of the descriptive statistics were presented with narrative texts and tables. To identify the signicantly associated factors of Khat use, multivariable analysis was computed. In multivariable analysis, a Pvalue of less than 0.05 was used as a base to identify the significance level of associated factors with Khat use with the corresponding 95% CI.

Sociodemographic factors
Among a total of 300 individuals invited to participate, 296 (98.6%) participated and completed the interview. Most (68.9%) participants were females. And 51.7% of the participants were within the age range of 29-48 years, and. (Table 1)  (Fig.1).

Correlates of dysmenorrhea
Rural residency, male gender, alcohol consumption and longer follow up schedule had significant association with current regular Khat use. (Table 3) This discrepancy might be explained by the difference in the operational definitions of Khat use. In our study current Khat use was measured for the use of khat for the last one month and others used define Khat use as "using of Khat for the previous one year".
Moreover, Dire Dawa is found near to the border of Ethiopia in which Khat is more commonly used than the other parts of the country [2].
The multi variable analysis result of this study showed that the odds of khat chewing among males were 2.4 times higher as compared to females. This might be explained by the fact that Khat chewing is more social taboo for females in Ethiopia,. Furthermore, males are commonly exposed in Khat chewing areas and had a peer influence of chewing, and females are commonly stayed stay at home [2,18].
Individuals resided in rural areas are 2.4 times more likely to chew Khat as compared to urban communities. This might be due to the highly accessible and cheaper price of Khat in the rural area as is commonly cultivated in the rural part of our study area. In addition, people from rural areas might not have adequate knowledge about the problems of Khat use for people on HAART [16].
Patients with an HIV/AIDS follow up visit of "Every six months" were 5 times more likely to use Khat as compared to patients with monthly follow up visits. This is This study was ethically approved by from Dilla University, college of health and medical science. A brief explanation about the scope and purposes of the study was given to each participant, and then requested to provide written consent of participation. All participants have been informed that they have the right to refuse and or withdraw their participation at any time, and there will not be any harm will be imposed to them due to their refusal or withdrawal.
