Association of cigarette excise taxes and clean indoor air laws with change in smoking behavior in the United States: a Markov modeling analysis.

The rates of cigarette smoking in the United States have declined over the past few decades in parallel with increases in cigarette taxes and introduction of more stringent clean indoor air laws. Few longitudinal studies have examined association of taxes and clean indoor air policies with change in smoking nationally. This study examined the association of state and local cigarette taxes and clean indoor laws with change in smoking status of 18,499 adult participants of the longitudinal 2010-2011 Tobacco Use Supplement of the Current Population Survey over a period of 1 year. Every $1 increase in cigarette excise taxes was associated with 36% higher likelihood of stopping smoking among regular smokers. We found no association between clean indoor air laws and smoking cessation nor between taxes and clean indoor air laws with lower risk of smoking initiation. Cigarette taxes appear to be effective anti-smoking policies. Some state and local governments do not take full advantage of this effective policy measure.

Assessing risk behaviours in the Iranian general population: results from the Iranian Mental Health Survey.

BACKGROUND: The Islamic Republic of Iran is a majority Muslim country, with a culturally low acceptance of high-risk behaviours. AIMS: To investigate co-occurrence of risk behaviours in the Iranian general population. METHODS: This was a cross-sectional study. Data were obtained from a random subsample of 3508 participants in the Iranian Mental Health Survey conducted in 2011 who completed a self-administered questionnaire about risk behaviours. The latent class analysis was performed on 7 behaviours consisting of cigarette smoking, alcohol consumption, opium use, use of other illicit drugs, having multiple sexual partners, imprisonment, and running away from home. Unordered multinomial logistic regression was performed to examine characteristics of participants in the latent classes. RESULTS: In the past 12 months, the rates of cigarette smoking, alcohol consumption, opium use, and use of other illicit drugs were 19.4%, 6.3%, 4.4%, and 4.2%, respectively. Three classes were identified: 1, a large class with low prevalence of risk behaviours [89.2%; 95% confidence interval (CI): 88.2-90.2%]; 2, high prevalence of all risk behaviours except drug use (6.1%; 95% CI: 5.3-6.9%); and 3, high prevalence of all risk behaviours (4.7%; 95% CI: 4.1-5.5%). Men and individuals with psychiatric disorders were over-represented in both classes 2 and 3. CONCLUSION: Alcohol consumers and opium users were at risk of other risky behaviours.

Psychiatric disorders among people living with HIV/AIDS in IRAN: Prevalence, severity, service utilization and unmet mental health needs.

BACKGROUND: HIV and psychiatric disorders are closely correlated and are accompanied by some similar risk factors. OBJECTIVE: The aim of this study was to assess psychiatric comorbidity and health service utilization for mental problems among people living with HIV/AIDS in Iran. METHODS: A total of 250 cases were randomly selected from a large referral center for HIV treatment and care in Tehran, Iran. Psychiatric disorders in the past 12 months including mood, anxiety, and substance use disorders were assessed through face-to-face interview, using a validated Persian translation of the Composite International Diagnostic Interview (CIDI v2.1). Severity of psychiatric disorders, social support, socio-economic status, service utilization and HIV-related indicators were assessed. RESULTS: Participants consisted of 147 men and 103 women. Psychiatric disorders were found in 50.2% (95% confidence interval: 43.8-56.6) of the participants. Major depressive disorder was the most prevalent diagnosis (32.1%), followed by substance use disorders (17.1%). In bivariate analysis, psychiatric disorders were significantly higher among male gender, single and unemployed individuals and those with lower social support. In multivariate regression analysis, only social support was independently associated with psychiatric disorders. Among those with a psychiatric diagnosis, 41.1% had used a health service for mental problems and 53% had received minimally adequate treatment. CONCLUSION: The findings of the study highlight the importance of mental health services in the treatment of people living with HIV/AIDS.

Profile of People Who Inject Drugs in Tehran, Iran.

The marked shift in the patterns of drug use in Iran, from opium smoking to injecting drug use, has led to serious health-related outcomes. This study was designed to explore characteristics of people who inject drugs (PWID) in Tehran, Iran. Nine hundred and four PWID were recruited from treatment and harm reduction facilities, as well as drug user hangouts in public areas in Tehran. Participants were interviewed using the Persian version of the World Health Organization Drug Injecting Study Phase II questionnaire. The median age at the time of the first illegal drug use, at the time of the first injection and current age was 20, 24 and 32, respectively. In more than 80% of the cases, the first drug used was opium. The transition from the first drug use to the first drug injection occurred after an average of 6.6 and 2.7 years for those who had started drug use with opium and heroin, respectively. Two-thirds of the participants shared injecting equipment within the last 6 months. Difficulty in obtaining sterile needles and thehigh cost of syringes were reported as the major reasons for needle/syringe sharing. Approximately 80% of community-recruited PWID reported difficulties in using treatment or harm reduction services. Self-detoxification and forced detoxification were the most common types of drug abuse treatment in alifetime. Despite a dramatic shift in drug policy in Iran during the past few years, wider coverage of harm reduction services, improvement of the quality of services, and education about such services are still necessary.

Transition to injecting drug use in Iran: A systematic review of qualitative and quantitative evidence.

BACKGROUND: Injection drug use, a behavior associated with significant adverse health effects, has been increasing over the past decade in Iran. This study aims to systematically review the epidemiological and qualitative evidence on factors that facilitate or protect the transition to injection drug use in Iran. METHODS: We conducted electronic searches in five international (Medline, Web of Science, EMBASE, CINAHL, PsycINFO), one regional (IMEMR) and three Iranian (Iranmedex, Iranpsych, IranDoc) databases, as well as contacting experts in the field. Two trained researchers screened documents to identify relevant studies and independently dual-extracted data following pre-specified protocol. We applied principles of thematic analysis for qualitative data and applied a random effect meta-analysis model for age of first injection. RESULTS: A total of 38 documents from 31 studies met eligibility criteria, from which more than 50% were implemented from 2006 to 2008. The weighted mean age of first injection was 25.8 (95% Confidence Interval: 25.3-26.2). Between 1998 and 2011, the age of first injection was relatively stable. Overall, drug users had used drugs for 6-7 years before they started injection use. Heroin was the first drug of injection in the majority of the cases. We identified factors influencing the initiation of or transition to injection use at various levels, including: (1) individual (pleasure-seeking behavior, curiosity and development of drug dependency commonly reported), (2) social and environmental (role of peer drug users in the first injection use, the economic efficiency associated with injections and the wide availability of injectable form of drugs in the market). CONCLUSION: Harm reduction policies in Iran have almost exclusively focused on drug injectors in Iran. However, given the extent of the non-injection drug use epidemic, evidence from this study can provide insight on points of interventions for the prevention of the transition to injection use.

Trend of smoking among students of Tehran University of Medical Sciences: results from four consecutive surveys from 2006 to 2009.

BACKGROUND: Smoking within students community of the medical sciences can negatively impact the attitudesof the society in future. The objectives of this study were to assess the prevalence and trends of smoking amongstudents of Tehran University of Medical Sciences. METHOD: This study was conducted in four consecutive years from 2006 to 2009. The study sample was takenfrom the first- to fourth-year, undergraduate and graduate (doctorate) students of Tehran University of MedicalSciences. Census was applied for sampling. Structured questionnaires were distributed to students of each class.The study was anonymous and self-administered. RESULTS: From 2006 to 2009, a total of 1568 to 1761 students participated in the study each year. Over thestudy period, i.e. 2006-2009, the prevalence of cigarette smoking was decreased (the overall prevalence was12.5% in 2006, 12.9% in 2007, 10.8% in 2008, and 10.5% in 2009). The corresponding values for the onemonth prevalence were 8.2%, 7.8%, 6.1%, and 5.8%, while those for the prevalence of daily smoking were3.4%, 4.0%, 2.9%, and 1.8%, respectively. The decreasing trend was particularly more significant for femalestudents. CONCLUSION: The findings suggest that the prevalence of smoking among students of Tehran University ofMedical Sciences was in the lower end of the spectrum, in comparison to other universities in Iran and othercountries. Additionally, similar to the pattern observed in the developed world, this trend was decreasing, particularlyamong girls. Implementing preventive measures for accelerating the decreasing trend, as well as continuousmonitoring is recommended.
