RESUMEN
OBJECTIVE: Despite the widespread awareness of the harms of smoking, millions continue to smoke around the world partly due to the difficulty it takes to quit smoking. Identifying the factors associated with making quit attempts is an essential pillar to reach successful quitting. The purpose of this study is to assess the factors associated with the past quit attempts and their past length of abstinence in a Lebanese sample of cigarette smokers. METHODS: This study was conducted between March 2014 and March 2015, involving 382 patients randomly chosen from 5 outpatient clinics in 5 hospitals in Lebanon. A standardized questionnaire was completed including socio-demographic characteristics, smoking behavior, chronic respiratory symptoms, Fagerstrom scale, Mondor scale, packaging perception, quitting behavior and readiness to quit ladder. RESULTS: Smokers who have chronic allergies (ORa=2.45, p=0.03), those who have ever stopped smoking for at least one month due to the warnings implemented on the packages (ORa=4.6, p<0.0001) and smokers with an intention to quit in 2months (ORa=2.49, p<0.0001) had significantly more past quit attempts. Furthermore, longer quit attempts duration (more than 1month) were significantly associated with low-nicotine dependent smokers (ORa=0.56, p=0.02), higher-motivated smokers (ORa=1.85, p=0.01), people with chronic allergies (ORa=2.07, p=0.02), smokers who have ever stopped smoking for at least one month due to the warnings (ORa=3.72, p<0.0001) and those with an intention to quit in 2months (ORa=1.98, p=0.05). CONCLUSION: The promoters of smoking cessation services should consider these factors when designing comprehensive tobacco control initiatives and in service planning.

Sexuality is still a taboo in Middle Eastern countries, and Lebanon is no exception. This study's objective was to evaluate attitudes towards sexuality and its practice among university students in Lebanon and assess their respective correlates. The cross-sectional study was carried out among students selected from seventeen universities across Lebanon. The participants received a self-administered standardized questionnaire that assessed their attitudes towards sexuality. It included questions on socio-demographic factors, risk-taking, risky behaviours and sexuality-related questions. Among 3384 students, 2700 (79.8%) answered the questions on sexuality. Around 15% had engaged in sexual activity, while 20% were regularly sexually active. Among males, 34.8% had never had sexual activity, 29.9% had tried it and 35.3% were regularly sexually active. Among females the results were respectively 85.1%, 5.3% and 9.6% (p<0.001). Only 36% regularly used condoms during their relationships. A liberal attitude towards sex, male sex, motives for risky behaviours, current cigarette smoking and problematic alcohol consumption were associated with sexual activity. Realizing that risky behaviours are dangerous, health concerns related to sexual relationships and a liberal attitude towards sex were associated with regular condom use. However, being bothered by condoms and female sex were inversely associated with condom use. Finally, participants who had motives for, and those who felt excited about risky behaviours, and those reporting current cigarette and waterpipe smoking and problematic alcohol consumption (ß=0.600; p=0.002) embraced a more liberal attitude towards sex. Conversely, females (ß=-7.58; p<0.001) and individuals who considered risky behaviours as dangerous reported an unfavourable attitude towards sexuality. A substantial proportion of Lebanese university students have regular sexual activity, but a low percentage use condoms for protection. Interventions are required among males in particular in view of these attitude and behavioural changes towards sexuality.

INTRODUCTION: Many studies have demonstrated that outdoor pollution might exacerbate respiratory symptoms and childhood asthma. Our objective was to evaluate the relationship between asthma and outdoor and indoor pollution. METHODS: We undertook a survey in May-June 2012 about schoolchildren aged 12-19 years in six Lebanese schools. This combined the International Study of Asthma and Allergies in Childhood (ISAAC) standardized questionnaire with other questions addressing outdoor and indoor exposure. RESULTS: Among 717 subjects (response rate 71.7%), 4.5% had physician-diagnosed asthma, 34.7% had probable asthma and 60.8% were asymptomatic. Exposure to indoor contaminants was positively associated to asthma. The risk for asthma was higher in those residing near heavy road traffic (ORa=4.30 [95% CI 1.45-12.71], P<0.05), those previously exposed to fire (ORa=1.84 [95% CI 1.01-3.36]), and those exposed to smog (ORa=4.15 [95% CI 1.42-12.12]). Airing the house in the morning or in case of indoor smoking had a protective effect against asthma. CONCLUSION: These results suggest that the risks of asthma or having respiratory symptoms are not only related to indoor pollution but also to outdoor pollution especially from road traffic.

Risky behaviours among young people are relatively frequent, with several motives and attitudes lying behind. Our objective was to evaluate the role of risk perception, attractiveness and motives for risk behaviour taking among university students in Lebanon. A cross-sectional study was carried out using a proportionate cluster sample of Lebanese students in public and private universities. Items of risk intake and perception scale, attractiveness of risky behaviours, and motives for risky behaviours were assessed, in addition to cigarette and waterpipe smoking and dependence, alcohol problematic consumption and mental distress scale. After verifying the validity of scales and reliability in the university students' population, we found that risk perception was associated with lower risk intake, while risk attractiveness was a driver for it. Moreover, motives differed in their driving of risky behaviour, a particular point was that women indicated more goal achievement objectives, the latter concept was associated with lower risk taking. University students in Lebanon, women in particular, demonstrated wiser behaviour and may benefit from heath education programme to increase their awareness about risky behaviours. Identifying other personal, environmental, social and psychological predictors may also be important to improve effectiveness of these programmes.
RESUMEN
OBJECTIVES: The objective of this study was to measure the correlates, including normative beliefs, associated with waterpipe (WP) and cigarette smoking prevalence and dependence. SETTING: A cross-sectional study was carried out using a proportionate cluster sample of Lebanese students in 17 public and private universities. PARTICIPANTS: Of the 4900 distributed questionnaires, 3384 (69.1%) were returned to the field worker. All available students during break times were approached, with no exclusion criteria. PRIMARY AND SECONDARY OUTCOME MEASURES: sociodemographic variables, detailed active and passive smoking, in addition to items of the tobacco dependence scales were all evaluated. RESULTS: Correlates to WP smoking were studying in a private university (adjusted OR, aOR=1.50 (1.26 to 1.79); p<0.001) and ever smoking cigarettes (aOR=1.80(1.44 to 2.26); p<0.001); friends' and societal influence were found on smoking behaviour and dependence. Although the role of parents was not visible in decreasing the risk of smoking WP, their protective influence seemed more important on WP dependence (ß=-1.09(-1.79 to -0.28); p<0.001), a behaviour that is considered more deleterious for health. Parents' and friends' disagreement with smoking had a protective effect on cigarette smoking and dependence (aOR<1; p<0.01), while thinking that idols and successful people smoke increased the risk of both cigarette smoking and dependence (aOR>1; p<0.01). CONCLUSIONS: In conclusion, WP smoking and dependence are influenced by parents' and friends' opinions, and idols' smoking status. Future research is necessary to further improve our understanding of motives for WP smoking and dependence.

BACKGROUND: Cigarette smoking induces dependence. PURPOSE: The primary objective of this work was to validate the use of the Fagerström test for nicotine dependence (FTND) in the Lebanese population, and to broaden it eventually by adding new items covering DSM-IV and ICD-10 dependence components. METHODS: We used data from two samples: a cross-sectional national study and a case-control study. A standardized questionnaire was administered, with items related to cigarette dependence: the FTND and the new Lebanon Cigarette Dependence (LCD) scale. For both tools, an exploratory factor analysis was performed on sample 1, while confirmatory factor analysis was performed on sample 2. RESULTS: Although the FTND test showed satisfactory psychometric properties, the LCD showed better validity and reliability, covered dependence concept better, and showed a higher correlation with the number of times the participant tried to stop smoking (r = -0.087; p = 0.029 versus r = -0.215; p < 0.001). CONCLUSIONS: FTND could be used in the Lebanese population; however, the LCD scale may be more useful.

BACKGROUND: Although Lebanon is a highly polluted country, so far no study has specifically been designed to assess the association between outdoor air pollution and chronic bronchitis in this country. OBJECTIVE: To assess the association between exposure to outdoor air pollution and chronic bronchitis in Lebanon. METHODS: A pilot case-control study was conducted in two tertiary care hospitals. Cases consisted of patients diagnosed with chronic bronchitis by a pulmonologist and those epidemiologically confirmed. Controls included individuals free of any respiratory signs or symptoms. After obtaining informed consent, a standardized questionnaire was administered. RESULTS: Bivariate, stratified (over smoking status and gender) and multivariate analyses revealed that passive smoking at home (ORa: 2.56, 95% CI: 1.73-3.80) and at work (ORa: 1.89, 95% CI: 1.13-3.17); older age (ORa: 1.75, 95% CI: 1.55-2.39); lower education (ORa: 1.44, 95% CI: 1.21-1.72); living close to a busy road (ORa: 1.95, 95% CI: 1.31-2.89) and to a local power plant (ORa: 1.62, 95% CI: 1.07-2.45); and heating home by hot air conditioning (ORa: 1.85, 95% CI: 1.00-3.43) were moderately associated with chronic bronchitis; an inverse association was found with heating home electrically (ORa: 0.58, 95% CI: 0.39-0.85). A positive dose-effect relationship was observed in those living close to a busy road and to a local diesel exhaust source. CONCLUSION: Chronic bronchitis is associated with outdoor air pollution.

Waterpipe smoking and its association with chronic bronchitis has not been assessed in Lebanon. This case-control study in Beirut in 2009/2010 evaluated this relationship: 274 cases of chronic bronchitis and 559 controls without the condition aged > or = 40 years were enrolled. Data were collected by questionnaire on: sociodemographic characteristics, respiratory symptoms, smoking (waterpipe and cigarette) and nicotine dependence. ANOVA, Student, Kruskal-Wallis, chi-squared and Fisher exact tests were used when applicable and logistic regression analysis was carried out. Previous waterpipe smoking (OR = 6.4), previous mixed smoking (OR = 38.03) and current mixed smoking (OR = 7.68) were significantly associated with chronic bronchitis (P < 0.001 for all) but current exclusive waterpipe smokingwas not (OR = 1.87, 95% CI: 0.74-4.72). Current waterpipe dependence was significantly associated with chronic bronchitis (OR = 3.74, P < 0.001). After adjustment for covariates/confounders, ever waterpipe smoking > 20 WP-years (P < 0.001) was significantly associated with chronic bronchitis.

Waterpipe smoking and its association with chronic bronchitis has not been assessed in Lebanon. This case-control study in Beirut in 2009/2010 evaluated this relationship: 274 cases of chronic bronchitis and 559 controls without the condition aged >/=40 years were enrolled. Data were collected by questionnaire on: sociodemographic characteristics, respiratory symptoms, smoking [waterpipe and cigarette] and nicotine dependence. ANOVA, Student, Kruskal-Wallis, chi-squared and Fisher exact tests were used when applicable and logistic regression analysis was carried out. Previous waterpipe smoking [OR = 6.4], previous mixed smoking [OR = 38.03] and current mixed smoking [OR = 7.68] were significantly associated with chronic bronchitis [P < 0.001 for all] but current exclusive waterpipe smoking was not [OR = 1.87, 95% CI: 0.74-4.72].

BACKGROUND: Venous thromboembolism (VTE) is a major worldwide problem. OBJECTIVES: The primary objectives of this survey were to identify patients at risk for VTE, to define the rate of patients receiving appropriate VTE prophylaxis and to examine the frequency of the presence of guidelines and their application. PATIENTS AND METHODS: Ten countries, 101 hospitals and a total of 4983 patients were included in this multinational cross-sectional survey. Standardized case report forms were filled out by trained individuals on one predefined day. Risks were categorized according to the Caprini Risk Assessment Model. Logistic regressions were carried out to assess factors that determined VTE prophylaxis. RESULTS: Of 4983 patients, 3368 (68%) and 1615 (32%) were surgical and medical, respectively. Seven hundred and seventy-two (15.5%) were considered to be at low risk, 1001 (20%) at moderate risk, 1289 (26%) at high risk and 1921 (38.5%) at very high risk for VTE. Of 3575 (72%) patients who were eligible to receive VTE prophylaxis, 2747 (77%) received any drug prophylaxis. Among these patients 720/1056 (68%) and 2027/2519 (80%) were medical and surgical patients, respectively. The overall compliance with ACCP guidelines was 38%, being 24% for medical patients and 44% for surgical patients. CONCLUSIONS: The results of this large multinational survey, although indicating overall improvement in VTE prophylaxis, identify a considerable number of patients who either did not receive any VTE prophylaxis or received it inappropriately. Although more medical patients were at risk for VTE, they were given prophylaxis less frequently than surgical patients. Concordance with VTE prophylaxis guidelines was higher in surgical patients, but overall application of these tools was unacceptably low.

We carried out a comparative study to assess the demographic and social characteristics of water pipe (WP) smokers, the association with cigarette smoking and chronic respiratory diseases and the dependence profile on 4 groups: exclusive WP smokers, exclusive cigarette smokers, mixed smokers and absolute non-smokers. Cigarette smoking was statistically significantly higher in WP smokers than non-WP smokers; 36.5% of exclusive WP smokers smoked > or =7 WPs/week. Chronic respiratory disease and chronic bronchitis were reported more frequently in exclusive WP smokers than absolute non-smokers. WP smoking seems to be as great a risk factor as cigarette smoking for chronic respiratory disease.

OBJECTIVES: To determine the prevalence of asthma, allergic rhinitis and eczema in Lebanese children. STUDY DESIGN: Descriptive cross-sectional study on children in public and private schools in Lebanon. METHODS: Standardized written questionnaires were distributed to 5-12-year-old students at 22 schools. RESULTS: In total, 3909 individuals were analysed. The prevalence of diagnosed asthma (4.8%) was low, while the prevalence of allergic rhinitis was 21.2% and that of eczema was 11.8%. Marked variations and differences were found across the governates in Lebanon, with the lowest prevalence of diagnosed asthma (1.8%) in Bekaa and the highest prevalence in Beirut (11.6%). CONCLUSION: Asthma symptoms, rhinitis and eczema have medium prevalence in Lebanon compared with worldwide data. Compared with other countries in the Eastern Mediterranean Region, the prevalence of 12 months of wheezing, night cough and wheezing on exercise were highest in Lebanon, but were much lower compared with English-speaking countries. Further studies are needed to understand the environmental, climatic and socio-economic causes of these discrepancies.

We compared the respiratory function of 19 pesticide factory workers and a control group of 43 other factory workers in Lebanon. The groups had no difference in smoking status. Baseline measurements of respiratory function showed significantly lower forced expiratory volume and flow rates (FEV1, FEF(25-75%), and FEV1/FVC ratio) among subjects working with pesticides, i.e. obstruction may be linked to chronic exposure to pesticides. After 4 hours of work, all respiratory variables were still significantly lower in pesticide-exposed subjects, but no acute changes in respiratory function were seen. Pesticide-exposed workers had 5.6 times higher risk of abnormal FEV1/FVC ratio and 16.5 higher risk for abnormal FEF(25-75%). Duration of occupation in the pesticide factory was significantly correlated with abnormal respiratory measures.

Pulmonary function studies are often limited to the alone measurement of transfer lung factor for CO (TLCO) in screening for pneumonia in patients with Human Immunodeficiency Virus (HIV) infection. We prospectively measured pulmonary function tests (PFT) in 112 HIV seropositive patients. The population consisted of two groups: on one hand, a group free of clinical and radiological abnormalities, on the other hand, one with respiratory symptoms and/or abnormal chest X-Ray, with or without overt pneumonitis. For this latter group, a fiberoptic bronchoscopy with bronchoalveolar lavage was routinely performed in addition to PFT. In case of pneumonitis, PFT showed a restrictive disease and a reduced TLCO. The specificity of this functional pattern was however weaker in the subgroup of drug abusers than in the non-drug addicts. This difference was above all linked to a low TLCO value in the subgroup of drug addicts without pulmonary complications. Multivariate statistical analysis, including discriminant analysis, maintained the same sensibility and improved specificity of PFT in diagnosis of pneumonia, especially if the analysis takes the existence of drug abuse into account. Moreover, initial PFT, performed before any lung disease, improved the sensibility of the screening. The results are discussed in relation to new tests proposed for the screening of pneumonitis in HIV positive patients. At the present time, PFT seems to be useful and enables one to understand natural functional evolution.

A patient with chronic obstructive pulmonary disease and acute respiratory failure developed grand mal seizures in the hours following onset of mechanical ventilation. These seizures were associated with an acute increase in arterial pH and were related to the occurrence of acute severe hypophosphataemia associated with recovery from respiratory acidosis.
