Individual and community-level factors associated with khat ( Catha edulis) use among women of reproductive age in Halaba zone, South Ethiopia: a multilevel mixed effect analysis. Front Psychiatry 2024; 15:1333556. [PMID: 38439793 PMCID: PMC10910081 DOI: 10.3389/fpsyt.2024.1333556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Accepted: 01/30/2024] [Indexed: 03/06/2024] Open
Abstract
Introduction There is a paucity of data on factors associated with khat chewing among women of reproductive age using multilevel analysis. Furthermore, the effects of some potential factors like stressful life events, knowledge about and attitude toward the effects of khat have been given little attention and are not well understood. Therefore, this study aimed to examine the prevalence and multilevel factors associated with khat use among women of reproductive age in Halaba zone, South Ethiopia. Methods A community-based cross sectional study was conducted in Halaba zone from February to July, 2023. Systematic random sampling technique was used to include 1573 study participants. The dependent variable was current khat use, which is operationalized as using khat within 30 days preceding the study. An interviewer administered questionnaire was used for the data collection. Results The prevalence of current khat use among women of reproductive age was 65.9% [95%CI (63.5-68.2%)]. Factors significantly associated with khat use were; ages of women 35 and above years [Adjusted Odds Ratio (AOR) = 6.35, 95% CI: (3.62, 11.13)], ever married [AOR = 2.41, 95% CI: (1.10, 5.31)], secondary and above education [AOR = 0.28, 95% CI: (0.15, 0.49)], belong to richer household [AOR = 1.75, 95% CI: (1.12, 2.75)], mass media use [AOR = 3.12, 95% CI: (1.85, 4.81)], low knowledge about khat effects [AOR = 3.12, 95% CI: (1.85, 5.24)], positive attitude towards khat use [AOR = 11.55, 95% CI: (6.76, 19.71)], and strong social support [AOR = 0.43, 95% CI: (0.28, 0.64)] and non-user friend [AOR = 0.31, 95% CI: (0.20, 0.48)]. From the community level variables: rural residence [AOR = 5.06, 95% CI: (1.82, 14.09)] was significantly associated with khat use. Conclusion Khat use among women of reproductive age was found to be very high. From individual-level factors: advanced ages of women, secondary and above education, live in the richer wealth quintile, mass media exposure, low knowledge on khat effects, positive attitude towards khat use, strong social support, and from community-level variables: residing in rural area were significantly associated with khat use. Khat use screening for all women of childbearing age, as well as referral to substance use disorder centers for those women identified as having khat use disorder, should become a standard of care in all health facilities.

Abstract
Objectives The purpose of this study was to assess the effects of habitual chewing of khat (Catha edulis) on blood pressure, body mass index, and physiological aspects of sexuality among residents of an Ethiopian town. Methods A statistically determined and randomly selected sample of khat-chewing individuals in the town of Hosanna in Southern Ethiopia were included in the study. We used physical measurements and a self-administered questionnaire to collect the data, which was statistically analyzed. Results The participants comprised a total of 420 with mean age = 28.7±5.7 years; 336 (80.0%) were male. Nearly half (201; 47.9%) were in the age-group 30-34 years. The adverse effects of khat use were assessed from the median score of each outcome, namely, physical problems, abuse potential, and social effects. Having a score above the median on each of the three target outcomes was equated with the presence of adverse effects. Adverse effects were reported among 341 of 420 (81.2%) participants, of whom 277 of 341 (81.2%) were male and 64 of 341 (18.8%) were female. The reported adverse effects were significantly higher among those who co-used tobacco, coffee, or tea with khat, with adjusted odds ratio = 4.8; CI: 2.86-8.22. Conclusions Khat chewing was found to have a significant adverse effect on the health of individuals who indulged in it. This finding implies the need for urgent intervention from health authorities.

Abstract
Introduction Khat is a flowering plant with stimulant effect on the nervous system and produce psychological dependence. Despite its harmful effects, the ingestion of khat has been part of cultural norms and the legality of khat varies by region. Objective This systematic review aimed at critically evaluating the available evidence on the risk factors of khat chewing among adolescents. Methods A systematic review was conducted on published research studies from five databases Scopus, PubMed, Science-direct, Ovid and google scholar using keywords khat chewing OR qat chewing AND associated factors OR risk factors OR contributing factors AND adolescents OR teenagers. Articles included were either cross-sectional, cohort, case-control or qualitative studies which were published between the year 1990 till present. Excluded articles were the non-English written articles, descriptive studies and irrelevant topics being studied. Results Out of 2617 records identified and screened, six were included for the analysis and interpretation of the data. All included studies were cross-sectional study design. All six studies reported having family members who chewed khat significantly predict khat chewing among adolescents, followed by five articles for friends or peers who also chewed khat and four articles for male gender. Smoking was also found to have the highest odds (OR = 18.2; 95% CI: 12.95–25.72) for khat chewing among adolescents. Conclusion The review highlights the crucial role of family members, friends or peers and male gender to predict khat chewing among adolescents. Effectiveness of health promotion programs to educate and reduce khat chewing among adolescents will require active participation of family members and friends.

Abstract
Background This study aimed to explore the barriers and enablers to quitting khat from the perspective of users and the barriers and enablers to supporting users to quit from the perspective of healthcare professionals (HCPs). Methods The present qualitative study was conducted using semi-structured interviews and the Theoretical Domains Framework (TDF) to collect and analyse data. Findings Overall, 10 khat users and 3 professionals were interviewed. Beliefs about the consequences of continued use facilitated user’s decisions to quit. Social influences were both a barrier and an enabler. For professionals, the social influence of other colleagues and working together was key in enabling them to support clients. Social/professional role and identity was also an important enabler, as professionals saw supporting users to quit as an integral part of their role. A range of behaviour change techniques was identified as potential ways in which quitting attempts could be more successful, from the perspective of users and professionals. Conclusion The study reveals the complexity of khat chewing and quitting from the perspective of khat users, such as the varied influence of family and friends. It also identifies the many barriers and enablers that professionals experience when supporting individuals to quit, such as working with other professionals. There is little evidence for the effectiveness of current services provided for quitting khat or little information outlining how they were developed. Current services would benefit from evaluating the effectiveness of the interventions using established methodology. Recommendations have been provided for practice in the field of substance misuse.

Abstract
Background: Khat chewing has a negative impact on an individual's life. Objectives: The study was execute to assess health sciences students' knowledge and attitudes regarding khat use in Yemen. Methods: This survey involved health sciences students from Aden University. Approximately 500 participants were selected through convenience sampling. The data were collected using a structured and validated self-administered questionnaire. The data were tabulated and descriptively analyzed. Results: The total number of respondents was 500. Almost half of the students reported that they chewed khat (n = 239, 48%). Approximately 66% (n = 330) of the students spent 2000 Yemeni riyals or less (USD1 = YER249.9) per day on khat. The main reasons for chewing khat were 'it is a social habit' (n = 155, 31%), followed by 'it improves my concentration when studying or working' (n = 140, 28%). Students knew that the effects of khat are similar to those of amphetamines (n = 210, 42.0%) and that khat is addictive (n = 254, 50.8%). Additionally, they knew that cathinone is the dependence-producing constituent of khat leaves (n = 269, 53.8%). The students agreed with the following statements: 'I will advise people to cease khat use'; 'Khat chewing is harmful to health'; 'Children and adolescents should not chew khat'; 'Khat chewing helps people stay awake'; and 'Health professionals serve as role models for patients and the public'. Conclusions: Khat chewing is prevalent among Yemeni university health sciences students. Only about half of the students recognized health risks associated with khat use. Also, among those who used khat, students endorsed positive benefits such as improved concentration.

Abstract
INTRODUCTION AND AIMS Khat (Catha edulis) is a stimulant plant widely used in East Africa and the Arabian Peninsula. Tobacco is often co-used with khat and its use has expanded to other parts of the world. Chronic khat use is associated with negative health consequences. There is a lack of research to develop a tool to assess attitudes toward khat use. This study aimed to develop a brief tool to assess attitude and perception related to khat (i.e. the Khat Knowledge, Attitudes and Perception Scale). DESIGN AND METHODS Four-hundred and three participants in Yemen (151 concurrent users of khat and tobacco, 141 khat-only users and 92 non-users of khat and tobacco) were asked about knowledge and attitudes related to khat. A principle component analysis with Promax rotation, Scree-plot and Cronbach's α coefficients was performed to examine psychometric properties of the Khat Knowledge, Attitudes and Perception Scale. RESULTS Principle component analysis revealed five factors: negative beliefs, positive beliefs, idleness, weight control and family issues. Internal consistency of items in negative beliefs, positive beliefs, idleness, weight control and family issues were 0.88, 0.62, 0.62, 0.72 and 0.53, respectively. Greater negative beliefs was inversely correlated with positive beliefs but positively associated with idleness, weight control and family issues. Concurrent users and khat-only users had lower scores on negative beliefs than non-users. Concurrent users had higher scores on positive beliefs than khat-only and non-users. DISCUSSION AND CONCLUSIONS These results provide initial support of the usefulness of the Khat Knowledge, Attitudes and Perception Scale.

Abstract
OBJECTIVE This study aimed to determine the efficacy of the Severity of Dependence Scale (SDS) as a screening tool for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition-defined khat use disorder. METHODS Cross-sectional, purposive sample of past-year khat consumers aged 16 and above were recruited from khat markets and cafes from university and general community in Adama, Ethiopia. Participants self-completed a survey comprising current substance use disorder. RESULTS The SDS formed a unifactorial structure, consistent with the dependence construct. Almost three quarters (73%) of the sample were identified as experiencing Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition khat use disorder. The SDS demonstrated excellent discrimination (area under the curve = 0.92) and an optimal cut-off as a score of 3 or greater, with sensitivity of 81% and specificity of 96%. This classification validly identified a group with more frequent and higher dose khat use than participants that did not screen positive. CONCLUSION Although khat is a mild stimulant, there is clear evidence that some consumers are both concerned with their use and experience problems associated with their use. Consistent with its application for other drugs, the SDS is a brief and simple screening tool that appears to validly identify individuals experiencing a khat use disorder syndrome and experiencing high rates of adverse consequences in association with use.

BMC Public Health 2016; 16:910. [PMID: 27582041 PMCID: PMC5007692 DOI: 10.1186/s12889-016-3588-6] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2016] [Accepted: 08/25/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND In Ethiopia, female smoking rates are currently low (1 %). However, because of male smoking rates (overall 7.7 % and up to 27 % depending on region), women and children's risk of second hand smoke (SHS) exposure is a pressing concern. In order to develop effective public health interventions that prevent the uptake and exposure to smoking, thereby averting the projected increase in tobacco-induced disease, an understanding of Ethiopian women's practices regarding tobacco is needed. The purpose of this study was to explore Ethiopian women's tobacco use and prevalence of SHS exposure, and to identify covariates associated with SHS exposure. METHODS We conducted an exploratory cross-sectional study in Southern Ethiopia between August and October 2014, and systematically sampled households in Aleta Wondo town and surrounding districts. Trained interviewers verbally administered surveys to women 18-55 years of age. Descriptive statistics and multiple logistic regression analyses were performed. RESULTS None of the 353 participants reported current tobacco use and less than 1 % reported ever use, however, 11 % reported ever use of the stimulant leaf khat. Twenty-seven women (7.6 %) reported living with a tobacco user, however, twice that number (14.4 %) overall, and 22 % of urban participants reported that smoking occurred daily in their home. When controlling for other factors, living with a tobacco user (OR = 9.91, 95 % CI [3.32, 29.59]), allowing smoking in the home (OR = 5.67, 95 % CI [2.51, 12.79]), place of residence (OR = 2.74, 95 % CI [1.11, 6.74)]), and exposure to point-of-sale advertising within the last 30 days (OR = 2.87, 95 % CI [1.26, 6.54]) contributed significantly to a model predicting the likelihood of reporting daily occurrence of smoking/SHS in the home. CONCLUSIONS While few women reported having ever used tobacco, one in seven women in this study reported that smoking/SHS occurred daily in their homes. Therefore SHS exposure is a potential health concern for women and children in this rural community. Findings from this study provide baseline data for monitoring tobacco control policies in Ethiopia, particularly in relation to the promotion of smoke-free homes, and could be used to inform prevention program development.

Abstract
The use of khat (Catha edulis) is a major public health and social problem that is believed to be growing globally. The khat chewing habit is prevalent in all areas of the Jazan region, Kingdom of Saudi Arabia (KSA). However, few studies have been conducted at the community level to investigate the khat chewing habits in this area. This study was conducted with the aim of assessing the prevalence and predictors of khat chewing among the Jazan community population. A cross-sectional study was conducted with a sample (n = 4,500) of the Jizani population who attended primary heath care centers in Jazan region. The participants were selected using a two-stage cluster random sampling. A structured questionnaire was used for data collection. The overall lifetime prevalence of khat chewing was 33.2% (95% CI 31.8-34.7) and was significantly higher for males 42.2% (95% CI 40.4-43.9) than for females 11.3% (95% CI 9.6-13.1) (P < 0.001). Current khat chewers accounted for 28.7% (95% CI 27.4-30.1) of the population sampled; 36.9% (95% CI 35.2-38.6) of whom were males, which is a significantly higher percentage than the 8.7% (95% CI 7.3-10.4) of current khat chewers who were females (P < 0.001). The multivariate logistic regression analysis suggests that the most important independent predictors of khat chewing were having a friend who chewed khat (OR = 20.1, P < 0.001), participant's smoking status (OR) = 3.9, P < 0.001), friend's smoking status (OR = 2.2, P < 0.001), gender (OR = 2.2, P < 0.001) and educational level (OR = 1.5, P < 0.05). A large proportion of the Jizani populations chew khat. Government and non-governmental organizations NGOs should design and strengthen community prevention programs to curb the high prevalence of khat use.

[PMID: 26066043 PMCID: PMC4465728 DOI: 10.1186/s12954-015-0048-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2015] [Accepted: 05/13/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Khat is a green leaf with amphetamine-like effects. It is primarily used among people in Africa, the Middle East and in the diaspora communities from these countries. Prior to the prohibition of khat in the UK on 24 June 2014, there was almost no information available on key aspects of the local khat market. METHODS A cross-sectional study was conducted in 2012 using snowball sampling, Privileged Access Interviewing and area mapping in order to identify khat sale establishments. Data was collected via face-to-face interviews using mixed methods for data collection. This included information about the establishments selling khat, khat pricing and its use among different ethnic minority groups, in addition to the potential sale of khat to children and risk assessment (e.g., use of pesticides on khat). RESULTS Five out of seven sellers identified agreed to participate. Sellers described their khat sale establishments as 'community centres' which included, for example, a restaurant basement. The sellers' history of selling khat ranged between 1-15 years and khat's sale took place between 2pm-10pm. Miraa (e.g., Lara) from Kenya was the most popularly used khat variety, sold in pre-wrapped bundles of approximately 250 g costing £3 each and delivered four days a week. Harari (e.g., Owdi) from Ethiopia was sold in 200 g, 400 g and 1 kg bundles, priced between £5 and £20 and delivered two days a week. The primary benefit of khat use was reported to be social interaction. The customers were predominantly adult males of Somali origin. Most sellers claimed a self-imposed ban on sales to children under 18 years old. Khat bundles had no labelling describing variety or weight and sellers had no knowledge of the use of pesticides on khat and did not advertise the risks associated with khat use. CONCLUSIONS Khat selling establishments were businesses that did not adhere to trade standards regulations (e.g., labelling khat bundles). They claimed to provide a community service (facilitating social interaction) to their predominately Somali customers. Without a better understanding of the dynamics of the khat market there is a risk that both health and social needs of the vulnerable populations involved in the market continue to go unaddressed. Future research should track changes in the now illicit khat market in order to evaluate the social and public health implications following the recent changes to the current U.K. regulatory environment regarding khat.

Abstract
Background Khat has amphetamine like effect. Students chew khat to stay alert. It has various negative physical, mental, social and cognitive effects. Poor academic performance has been associated with khat. The purpose of this study was to determine the prevalence and identify factors associated with khat chewing among Ethiopian University students. Methods A cross sectional study was conducted on Bahir Dar University Students. A self-administered questionnaire was completed by 3268 students. Proportion was calculated to estimate prevalence of khat chewing. Logistic regression was used to identify factors associated with khat chewing. Results Lifetime prevalence of khat chewing was 24% (95% Confidence Interval: 22.5%, 26.6%). Half of these are current khat users with a prevalence of 12.7% (95% Confidence Interval: 11.5%, 13.9%). Male students Adjusted Odds Ratio (AOR) = 3.3 (95% Confidence Interval: 1.8, 6.0), students living in off campus housing AOR = 3.0 (95% Confidence Interval: 1.5, 6.0), students who have khat user friends AOR = 4.2 (95% Confidence Interval: 2.6, 6.9), and students who perceive khat use improves academic performance AOR = 6.6 (95% Confidence Interval: 4.6, 9.5) are more likely to use khat. Conclusions Prevalence of current use of khat reported in this study is higher than recent study done on university students in Ethiopia and heavily influenced with peer practice.

Nakajima M, Dokam A, Alsameai A, AlSoofi M, Khalil N, al'Absi M. Severity of khat dependence among adult khat chewers: the moderating influence of gender and age. JOURNAL OF ETHNOPHARMACOLOGY 2014; 155:1467-1472. [PMID: 25064835 PMCID: PMC4167481 DOI: 10.1016/j.jep.2014.07.030] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2014] [Revised: 07/14/2014] [Accepted: 07/15/2014] [Indexed: 06/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The escalating use of khat (Catha edulis) in East Africa and Arabia is a major concern for public health. Yet little is known about the impact of khat on behavior. There has been no study in the region to assess the extent to which dependence syndrome is associated with khat use in this population. AIM OF THE STUDY To examine psychometric properties of the Severity of Dependence Scale-Khat (SDS-khat), gender differences in patterns of khat use and dependence, and the extent to which age moderated the link between gender and khat dependence. MATERIALS AND METHODS Two-hundred and seventy khat chewers recruited in two Yemeni cities completed face-to-face interviews asking about demographics and patterns of khat use. Validity of SDS-khat was examined by the principle component analysis and reliability of the scale was tested by Cronbach׳s alpha. A series of chi-square tests and analysis of variances (ANOVAs) were conducted to examine gender differences in khat use variables. RESULTS The results indicated that the mean age of khat chewers was 30.52 years (95% CI: 29.34, 31.70) and 52% of them were males. The SDS-khat was found to have two factors with moderate reliability. This pattern was consistent when the analysis was conducted in the entire sample and in each gender. Male khat chewers reported more symptoms related to khat dependence than female chewers. A significant gender by age interaction in SDS-khat levels (p=0.013) revealed a positive association between age and khat dependence in women only. CONCLUSION These results provide initial support for the use of SDS-khat in the assessment of khat dependence in Yemen. Gender differences in khat use patterns and dependence observed in this study call the need for more studies carefully examining the role of gender in khat research.

Concurrent tobacco and khat use is associated with blunted cardiovascular stress response and enhanced negative mood: a cross-sectional investigation. Hum Psychopharmacol 2014; 29:307-15. [PMID: 24706595 PMCID: PMC5763500 DOI: 10.1002/hup.2403] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2013] [Revised: 01/07/2014] [Accepted: 02/24/2014] [Indexed: 12/15/2022]
Abstract
OBJECTIVES Khat (Catha edulis), an amphetamine-like plant, is widely used in East Africa and the Arabian Peninsula and is becoming a growing problem in other parts of the world. The concurrent use of tobacco and khat is highly prevalent and represents a public health challenge. We examined for the first time associations of the concurrent use of tobacco and khat with psychophysiological responses to acute stress in two sites in Yemen. METHODS Participants (N = 308; 135 women) included three groups: users of khat and tobacco, users of khat alone, and a control group (nonsmokers/nonusers of khat). These individuals completed a laboratory session in which blood pressures (BP), heart rate, and mood measures were assessed during rest and in response to acute stress. RESULTS Concurrent use of khat and tobacco was associated with attenuated systolic BP, diastolic BP, and heart rate responses to laboratory stress (ps < 0.05) and with increased negative affect relative to the control group (ps < 0.05). CONCLUSIONS Results demonstrated blunted cardiovascular responses to stress and enhanced negative affect in concurrent khat and tobacco users. These findings extend previous studies with other substances and suggest that adverse effects of khat use may lie in its association with the use of tobacco.

Abstract
Khat chewing is associated with unfavourable health outcomes and family dysfunction. Few studies have addressed the factors associated with khat chewing among Yemeni women. However, the family and husband effects on chewing khat by women have not been addressed. This study aimed to determine the prevalence of khat chewing among Yemeni women and its associated factors, particularly husbands and family factors. A cross-sectional study was conducted among 692 adult Yemeni women in the city of Sana'a in Yemen using structured “face to face” interviews. Mean (±SD) age of women was 27.3 years (±6.10). The prevalence of chewing khat by women was 29.6%. Factors associated with chewing khat among women were chewing khat by husbands (OR = 1.8; 95% CI: 1.26, 2.53), being married (OR = 2.0; 95% CI: 1.20, 3.37), frequent family social gatherings (OR = 1.5; 95% CI: 1.06, 2.10), high family income (OR = 1.57; 95% CI: 1.12, 2.21), larger house (OR = 1.63; 95% CI: 1.16, 2.31), and age of women (OR = 0.64; 95% CI: 0.44, 0.92). It is concluded that khat chewing by women in this study was significantly associated with family factors and with khat chewing by their husbands. Urgent action is needed to control khat chewing particularly among women.

BMC Public Health 2014; 14:448.

Abstract
BACKGROUND Chewing khat leaves is often accompanied by tobacco use. We assessed aspects of tobacco use and explored factors associated with tobacco use patterns (frequency of use per week) among khat chewers who used tobacco only when chewing khat ("simultaneous tobacco and khat users", STKU). METHODS A sample of 204 male khat chewers was recruited during random visits to khat outlets. Data collected included socio-demographic items, tobacco use and khat chewing behaviours. Both psychological and physical dependence on khat were assessed using the Severity of Psychological Dependence on Khat (SDS-Khat) Scale, the Diagnostic Statistical Manual IV (DSM-IV) and adapted items from the Fagerström Test for Nicotine Dependence (chewing even when ill, and difficulty in abstaining from khat chewing for an entire week). Descriptive statistics and non-parametric analyses were conducted. RESULTS Of the 204 khat chewers, 35% were khat chewers only, 20% were STKU, and the remainder were daily cigarette smokers. The mean age of STKU was 38.12 (±14.05) years. Fifty seven percent of STKU smoked tobacco and chewed khat for two days per week and 43% smoked and chewed more frequently (three to six days: 33%, daily: 10%). Three quarters (74%) were former daily tobacco users. Khat chewing initiated tobacco smoking among 45% of STKU and 71% reported attempts to quit tobacco smoking during khat chew. Among STKU, smoking tobacco for more than two days per week was significantly associated (p < 0.05) with psychological dependence (increased levels of SDS-Khat), physical dependence (increased levels of DSM-IV symptoms, chewing even when ill, difficulty in abstaining from chewing for an entire week and self-reported health conditions) and behavioural factors (e.g. amount of khat chewed in typical khat session). CONCLUSIONS Khat chewing may promote different patterns of tobacco smoking, initiate and sustain tobacco smoking, and trigger tobacco cessation relapses among STKU. Increased frequency of tobacco smoking among STKU was linked to psycho-physical and behavioural factors. Further investigation within large and representative samples of both sexes of STKU in different contexts should be considered for health research and policy development. Khat chewing should be considered when designing tobacco prevention uptake, cessation interventions and relapse prevention programmes.

Abstract
Background The chewing of Khat leaves, a natural psychoactive substance is widely chewed in countries of East Africa and the southern Arabian Peninsula, and is reported to be associated with a range of unfavorable health outcomes including khat dependence. The impact of Khat chewing on Health Related Quality of Life is yet to be explored. Aims: to measure and compare the quality of life of the khat chewers and non-khat chewers using a short form health survey (SF36), and to assess factors associated with Khat chewing using SF36 in a sample of adult population in Jazan region, Kingdom of Saudi Arabia. Methods A total of 630 participants from two independent male populations of khat chewers and non-khat chewers were recruited into a cross-sectional survey study. A self administrative survey based on the SF-36 questionnaire was used to collect data on measures of health-related quality of life (HRQoL). Socioeconomic data of the respondents were also collected for detailed analysis. Data analysis include: descriptive statistics, reliability tests (Cronbach’s alpha and intraclass correlation coefficient), and bivariate analysis (Chi square and Mann–Whitney U-test) to compare HRQoL of Khat chewers and non-Khat chewers. Results The odds of being a khat chewer were higher in respondents with a lower socioeconomic status. The SF-36 scores were significantly lower in all domains for respondents with khat chewing, indicating that non-khat chewers had higher health perceptions compared with those chewing khat. The overall mean score of HRQoL for non-khat chewers was 92.7% (SD 5.53) compared with 63.5% (SD 21.73) for the khat chewing group. The study had shown good internal consistency and reproducibility across the eight subscales of SF-36 questionnaire (α 0.74-0.95). The Mann–Whitney U-test showed a significant difference between khat chewers and non-khat chewers (P < 0.001). Conclusions This study measured and compared the quality of life of khat chewers and non-khat chewers using a generic health survey (SF36). The study had shown that khat chewing is associated with lower quality of life (HRQoL) and lower socioeconomic status. However in future a more refined SF36 developed especially for Khat chewers can provide more useful information.

Abstract
OBJECTIVES (1) To estimate the prevalence and behavioral patterns of Khat chewing and (2) to investigate factors that influenced the pattern of Khat use among undergraduate students in different higher education institutions in Jazan region, Saudi Arabia. MATERIALS AND METHODS A cross-sectional study using a pretested structured self-administered quantitative questionnaire was used to collect data. SPSS version 17 software program was used for data analysis. RESULTS The overall current Khat chewing prevalence among higher education students was found to be 23.1%, significantly higher among males at 38.5% than among females at 2.1% (P < 0.001). Lifetime Khat chewer students were 24.8% for males at 40.5%, significantly higher compared with females at 3.7% (P < 0.001). Univariate analysis revealed that the gender of student, smoking status of student, a friend's smoking, and Khat chewing were associated with a significant high risk of Khat chewing (P < 0.001 for all). CONCLUSIONS The use of Khat trend is increasing among higher education students in Jazan region. A multilevel, value based, comprehensive, and strategic long-term intervention plan is needed. The comprehensive plan may include social interventions geared by creating recreations alternatives and opportunities for youth and a critical review for current authorities' interventions and services.

[PMID: 23454606 DOI: 10.1016/j.jep.2013.02.011] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2012] [Revised: 02/01/2013] [Accepted: 02/02/2013] [Indexed: 06/01/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Khat is a natural psychostimulant that has pharmacological effects similar to that of amphetamine. The behaviour of khat chewing is embedded within a cultural context. Meanwhile khat chewing is associated with psychological and physiologically burden, as a 'dependence producing' substance. AIMS OF THE STUDY To assess the applicability of the construct of substance dependence syndrome (DSM-IV, 1994) to khat chewing and to examine psychosocial and behavioural correlates of this syndrome including tobacco use. MATERIALS AND METHODS A sample of 204 khat chewers was recruited during random visits to khat sale outlets. A face to face interview that assessed socio-demographic, psychosocial dependence, substance dependence syndrome and behavioural characteristics was conducted. Descriptive, exploratory psychometric and multivariate analyses were employed. RESULTS Approximately a third (31%) of khat chewers reported symptoms consistent with dependence syndrome including increased khat chewing (13%) and cessation attempts (19%) while 17% reported withdrawal symptoms including depression (61%), increase in appetite (74%) and interrupted sleep (58%). Thirty-eight percent reported continued khat chewing despite impacts on their health. Psychometric assessment of the DSM-IV criteria for khat chewing dependence identified two factors; factor 1 consisted of bio-behavioural items and factor 2 withdrawal items, accounting for 67% of the variance and Cronbach's alpha coefficient at 0.78. In multivariate logistic regression modelling, there was an association between intensity of psychological khat dependence (SDS-Khat) and nicotine dependence with the likelihood of exhibiting khat chewing dependence syndrome (p=0.0005, OR=1.51, 95%CI=1.33-1.71; p=0.043, OR=2.87, 95%CI=1.03-7.98, respectively). CONCLUSIONS The substance dependence syndrome criteria are applicable to khat chewing and associated with increased intensity of nicotine and psychological khat dependence. The applicability of khat dependence syndrome and exploration of its dimensions and associated factors should be extended in future research. Concurrent validation of these findings using specific objective measures for self-report khat chewing is also recommended.
