“…The study also revealed that 3 out of 10 respondents consumed energy drinks, which is found to be strongly associated with sleep quality. This is in general agreement with prior studies (Aslam et al, 2013;Lemma et al, 2012;Reissig, Strain, & Griffiths, 2009;Velez et al, 2013). Besides caffeine, which is the main stimulant of energy drink, it may also contain other stimulating ingredients.…”

Background: The goal of this study is to evaluate the extent to which caffeine consumption, cigarette smoking, technology use, and academics are associated with the sleeping habits of university students. Methods: 643 undergraduate students aged 18 to 23 from five universities of Karachi completed a cross-sectional survey about sleep patterns and lifestyle habits between December 2014 and November 2015. Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality. Data was entered and analyzed using SPSS version 22. Pearson Chi-square test was applied to determine relationship between sleep patterns and factors affecting sleep. Threshold of significance was set at <0.05. Results: Majority of the participants (60.5%) reported poor sleep quality (PSQI score >5), with an average PSQI score of 6.5 (±3.033). Sleep duration was less than 7 hours for 71.8% (N=462) of the participants. Also, most participants went to bed between 9pm to 12am, with 52.5% of males (N=136) sleeping after 12am compared to 46.1% (N=177) of the females. Other than energy drinks, no stimulant beverage showed significant relation with sleep quality. However, coffee, tea and energy drinks had a negative impact on sleep onset latency. Smoking too showed an association with poor sleep quality (p-value <0.009) and delayed sleep onset (p-value <0.009). Mobile phone was by far the most frequently used technological device. Conclusions: Poor sleep quality is prevalent among college students of Karachi. Behavioral habits like consumption of caffeinated drinks, smoking, and technology use are associated with increased odds of poor sleep quality.

“…The growing research evidence shows that khat is a risk factor for different cardio-vascular disorders such as hypertension, ischemic heart diseases, and stroke 3,4 . Khat is also a risk factor for poor oral health 5 , psychosis 6 , mental distress 7 , anemia 8 , poor quality of life 9 , disturbed sleep pattern [10][11][12] , and duodenal ulcer 13 .…”

Background: Khat use is a well-established public health problem in Yemen, Arabian Peninsula, and Ethiopia. Along with its large scale production, the magnitude of khat use is increasing among students. Objective: This study was intended to assess the prevalence, determinants, and effect of khat use on academic performance of high school students in Sidama Ethiopia. Methodology: A cross-sectional study was conducted from April to June 2015. We used a stratified sampling technique to draw a total of 1,577students. The data was collected using self-administered questionnaires and analyzed using SPSS version 20. Descriptive statistics and logistic regression models were used to determine the prevalence, effects, and predictors of khat use. Result:The life time and current prevalence of khat use were 14.6% and 13%, respectively. Smoking cigarette (AOR=5.1, 95% C.I: 2.3-14.3), drinking alcohol (AOR=3.0, 95% C.I: 1.4-6.3), having a family growing khat (AOR=2.0, 95% C.I: 1.1-2.5), having friend chewing khat (AOR=3. 95% C.I: 2.0-4.6), were some of factors that increased the odds of students' khat use. Student's khat use increased the odds of student's poor academic performance (AOR=2.1, 95% C.I: 1.1-3.9). Conclusion:The prevalence of khat use in high khat producing districts of Sidama and its contribution to poor academic performance demand prompt intervention.

“…Associations between khat dependence and sleep disturbances or negative affect have not been examined, although this is an important question in light of studies showing insomnia (25) and negative mood (11) among khat users. This question is clinically relevant because insomnia and negative affect are related to one another (26,27) and both have implications for many health conditions (28,29).…”

Chronic khat use is associated with negative health consequences. However, no study has fully characterized individuals who are khat dependent. This paper examines socio-demographic and psychosocial correlates of adult khat dependence. A total of 270 khat users (129 women) in Yemen completed face-to-face interviews and provided demographic information and data on patterns of khat use, subjective mood, and sleep quality. The Severity of Dependence Scale-Khat (SDS-khat) was used to assess level of khat dependence. A series of analysis of variance was conducted. Khat users, on average, used khat for 5.2 hours a day (SD = 2.3) for 5.7 days a week (SD = 2.0). Individuals who screened positive for khat dependence reported longer duration of khat sessions per day, higher frequency of khat use per week, greater levels of negative mood and sleep disturbances, and were more likely to endorse physical symptoms after khat use (P < 0.05). Future research should elucidate mechanisms responsible for khat dependence symptomatology. Niveau de dépendance au khat, modes de consommation, et corrélats psychosociaux au Yémen : enquête transversaleRÉSUMÉ La consommation chronique de khat est associée à des conséquences néfastes sur le plan de la santé. Cependant, aucune étude n'a permis une caractérisation complète des individus dépendants au khat. Le présent article se penche sur les corrélats socio-démographiques et psychosociaux de la dépendance au khat chez l'adulte. Au total, 270 consommateurs de khat (129 femmes) au Yémen se sont soumis à des entretiens en face à face et ont fourni des informations démographiques et des données sur les modes de consommation, l'humeur subjective et la qualité du sommeil. L'Échelle de la sévérité de la dépendance pour le khat a été utilisée pour évaluer le niveau de dépendance à cette substance. Une série d'analyses de variance a été réalisée. Les utilisateurs de khat en consommaient, en moyenne, pendant 5,2 heures par jour (ET = 2,3) 5,7 jours par semaine (ET = 2,0). Les individus dépistés positifs pour la dépendance au khat signalaient des séances de consommation de khat de durée plus longue par jour, une fréquence plus élevée de consommation par semaine, des niveaux plus importants d'humeur négative et de troubles du sommeil, et étaient davantage susceptibles de ressentir des symptômes physiques après en avoir consommé (p < 0,05). La recherche future devrait s'efforcer de déterminer les mécanismes responsables de la symptomatologie de la dépendance au khat.
