Although the number of khat chewers has increased from time to time in Ethiopia, the direction (increased or decreased) of khat chewing on sexual desire is not well known due to the absence of adequate studies. Therefore, this study aimed to assess the effect of khat chewing on sexual desire in adults.
A comparative cross-sectional study was conducted in Logia town. A total of 334 study subjects, comprising 167 khat chewers and 167 non-khat chewers, were included in this study. House-to-house data were collected using the purposive sampling method. To estimate the effect of khat chewing on sexual desire, propensity score matching analysis with a logit model was used to find the average treatment effect (ATE) on the treated and untreated groups. The matching quality was checked statistically and graphically. Logistic regression was used to determine factors associated with sexual desire.
About 54.5% of respondents had poor sexual desire. Among khat chewers, 28.1% had poor sexual desire. According to logistic regression analysis, sexual desire was 2.8 times higher in adults aged 18-25 years (AOR = 2.8, 95% CI: 1.02-7.8). Sexual desire was lower in traders (AOR = 0.32, 95% CI: 0.15-0.69), low-income level (AOR = 0.37, 95% CI: 0.16-0.86), and cigarette smokers (AOR = 0.4, 95% CI: 0.2-0.73). There was no significant association between khat chewing and sexual desire (AOR = 0.91, 95% CI: 0.53-1.5). In propensity score matching analysis, the average treatment effect (ATE) on adults who chewed khat was 18.9%, meaning an average increase in sexual desire of 18.9%. The treatment impact on the treated group (ATT) was found to be 24.2%, indicating that 24.2% increased sexual desire among the treated groups (khat chewing).
More than half of adults had poor sexual desire. Logistic regression analysis revealed that sexual desire is moderated by age, occupational status, income level, and use of cigarettes. In the propensity score matching analysis, khat chewing can significantly increase the levels of sexual desire.
尽管在埃塞俄比亚，恰特草咀嚼者的数量时有增加，但由于缺乏充分的研究，恰特草咀嚼对性欲的影响方向（增加或减少）尚不清楚。因此，本研究旨在评估恰特草咀嚼对成年人性欲的影响。
在洛吉亚镇进行了一项比较横断面研究。本研究共纳入334名研究对象，包括167名恰特草咀嚼者和167名非恰特草咀嚼者。采用目的抽样法逐户收集数据。为了评估恰特草咀嚼对性欲的影响，使用logit模型进行倾向得分匹配分析，以找出治疗组和未治疗组的平均治疗效果（ATE）。通过统计和图形方式检查匹配质量。采用逻辑回归确定与性欲相关的因素。
约54.5%的受访者性欲较差。在恰特草咀嚼者中，28.1%的人性欲较差。根据逻辑回归分析，18至25岁成年人的性欲高2.8倍（优势比[AOR]=2.8，95%置信区间[CI]：1.02 - 7.8）。商人（AOR = 0.32，95% CI：0.15 - 0.69）、低收入水平（AOR = 0.37，95% CI：0.16 - 0.86）和吸烟者（AOR = 0.4，95% CI：0.2 - 0.73）的性欲较低。恰特草咀嚼与性欲之间无显著关联（AOR = 0.91，95% CI：0.53 - 1.5）。在倾向得分匹配分析中，咀嚼恰特草的成年人的平均治疗效果（ATE）为18.9%，这意味着性欲平均增加18.9%。治疗组的治疗效果（ATT）为24.2%，表明治疗组（咀嚼恰特草）中有24.2%的人性欲增加。
超过一半的成年人性欲较差。逻辑回归分析显示，性欲受年龄、职业状况、收入水平和吸烟情况的影响。在倾向得分匹配分析中，咀嚼恰特草可显著提高性欲水平。
