Behavioral Interventions for Tobacco Cessation in Low and Middle-Income Countries: A Systematic Review and Meta-analysis.

An estimated 78% of the total deaths attributable to smoking tobacco use occurred in low- and middle-income countries (LMICs) in 2019. In addition, smokeless tobacco increases the risk of all-cause mortality, all cancers including upper aero-digestive tract cancer, stomach cancer, ischaemic heart disease (IHD) and stroke; with 88% of the mortality burden being borne by the South-East Asian region. Evidence-based interventions from high income countries (HICs) are not easily transferable to LMICs, as patterns of tobacco use, health beliefs associated with tobacco use, and awareness of specific health risks vary substantially. We synthesised the effectiveness of behavioural interventions for tobacco cessation in LMICs through a systematic review and meta-analysis. Interventional studies which delivered individual behavioural intervention and assessed abstinence from tobacco use were included. We examined the pooled intervention effect at six months post-intervention follow up. For continuous abstinence at six months, the intervention was superior to active comparator (RR 2.32; 95% CI 1.78-3.02), and usual care (RR 4.39; 95% CI 2.38-8.11). For point prevalence abstinence at six months, the intervention was superior to active comparator (RR 1.76; 95% CI 1.28-2.44), and usual care (RR 2.37; 95% CI 1.47-3.81). The statistical heterogeneity was substantial to considerable for all comparisons. Only six studies had an overall low risk of bias. Publication bias was observed for all comparisons, except for 6-month continuous outcomes. Implementation research is needed to understand factors for programme sustainability and equity of impact of behavioural interventions in reducing tobacco use in LMICs. Our review is an important step towards the understanding of effectiveness of behaviour interventions for tobacco cessation suited for low- and middle-income countries and which are responsive to the contextual needs of such countries.

Prevalence of substance use among adolescents residing in urban slums of Vellore: A cross-sectional study

ABSTRACT Background: Adolescent substance abuse is a growing public health concern. Adolescence is the starting point for adult substance misuse. The likelihood of acquiring dependence in adulthood is significantly decreased when substance use is not initiated during adolescence. The purpose of this study was to estimate the prevalence of substance use among teenagers, as well as to determine the age of initiation and identify the factors that are linked to substance use. Methods: A community-based cross-sectional study was conducted in an urban community in Vellore by a tertiary care teaching hospital. A structured questionnaire was administered by the principal investigator to all adolescent boys aged between 10 and 19 years residing in that area for the past year who gave informed consent/assent to assess the prevalence of substance use among teenagers. Results: The total number of adolescent boys enrolled in the study was 266. The mean (standard deviation [SD]) age of the participants was 16.14 (2.2) years, with a median age of 16 years. Out of the 266 adolescent boys, 33.8% are currently using substances and 15% were past users. The common substance used was smoking tobacco (30%), followed by alcohol consumption (29%). The minimum age of initiation of smoking tobacco and ganja use was 9 and 7 years, respectively. Significant predictors of substance usage included the participant’s educational background and the substance use of their parents. Conclusion: According to this community-based study’s findings, smoking tobacco was the most frequently used substance by teenagers, with a higher prevalence of current substance use. Substance misuse in the family was substantially associated with increased drug usage among teenagers. Notwithstanding having an adequate comprehension of the negative results of substance utilisation, teenagers develop this habit, which they might carry into adulthood. It is therefore necessary to establish comprehensive prevention and control programs in schools and the community that target teenagers and their parents.

Tobacco Use, Food Insecurity, and Low BMI in India's Older Population.

Underweight is a prevalent condition among older adults in developing countries and poses a substantial burden on health, social, and aged-care systems. In this study, we examined the influence of tobacco use and food insecurity on the risk of being underweight among adults aged 60 or older in India. We used data from the 2017-2018 Longitudinal Aging Study in India. The sample size was 27,902 adults aged 60 years and above. We distinguished between smoking and smokeless tobacco use to examine how they may independently contribute to the outcome, while food insecurity was measured using the four-item version of the Food Insecurity Experience scale. Multivariable logistic regressions were conducted to assess the impact of tobacco use and food insecurity on the outcome. Additionally, we tested interactions between tobacco use and education, as well as between tobacco use and wealth. The prevalence of underweight was 27% in the study population. Older adults who used smoking tobacco were twice more likely to be underweight than non-users (OR = 2.07, 95% CI = 1.79 to 2.40, p < 0.001), controlling for other confounders. The positive association between smokeless tobacco use and underweight was weaker but still significant (OR = 1.26, 95% CI = 1.11 to 1.42, p < 0.001). Food-insecure older adults were also more likely to be underweight (OR = 1.27, 95% CI = 1.10 to 1.48, p < 0.001). Other risk factors of underweight included males, rural residents, lower socioeconomic status (in terms of education, wealth, and caste), chewing disability, poor self-rated health, chronic lung disease, and tuberculosis. Interestingly, tobacco use moderated the relationship between wealth and underweight, such that smokers are more likely to be underweight as they become more affluent. Tobacco use and food insecurity have adverse implications on the nutritional status of the older persons in developing countries such as India. More targeted tobacco cessation measures and active food assistance programs for older adults are warranted to improve the overall health status of the older demographic.

Behavior change, health, and health disparities 2024: Smoking and other tobacco use among women and girls

This Special Issue (SI) of Preventive Medicine is the 11th in an annual series on behavior change, health, and health disparities. The theme of this 2024 issue is Smoking and Other Tobacco Use among Women and Girls. Cigarette smoking remains the single most preventable cause of death in the U.S., causing the premature death of more than 200,000 U.S. women annually, a mortality rate that far exceeds levels from conditions more commonly associated with premature death in women (e.g., breast cancer). Of course, cigarette smoking among women and girls is also a well-known cause of intergenerational adverse health effects. Women and girls are also using e-cigarettes and many other tobacco products that are flooding the U.S. tobacco marketplace. This SI includes eleven peer-reviewed articles that advance knowledge across a wide range of topics on disproportionate adverse effects, prevalence, and risk factors for cigarette smoking and other tobacco use in women and girls.

Association of tobacco and alcohol consumption with hypertension among Hindu priests in Central India

Background: Alcohol and tobacco use are among the major risk factors for causing hypertension in the adult population globally as well as in India. India being a religious country harbor’s large number of Hindu temples which are conventionally managed by a dedicated population of Hindu priests. The prevalence of alcohol and tobacco use in this special population of priests in India is not well established along with the associated risk of hypertension. Aims and Objectives: First, to study the pattern of use of habit-forming substances; tobacco, alcohol, and cannabis derivatives among priests in central India. Second, to find the relationship between the use of tobacco smoking, chewing, and alcohol with hypertension. Materials and Methods: The current study is a cross-sectional survey on Hindu priests of registered temples of a Pilgrimage city in Central India. The study utilizes a pre-tested semi-structured questionnaire for interviewing 440 study participants. It included a sociodemographic profile, history of use of habit-forming substances, the presence of known hypertension, and measurement of blood pressure. Results: Out of 440 study participants; 280 (63.6%) were currently using habit-forming substances, whereas 160 (36.4%) number of participants had never used it. The current study found the prevalence of hypertension to be 31.9%. A statistically significant relationship of hypertension with the use of alcohol (χ2=44.2), tobacco chewing (χ2=106.1), and smoking (χ2=74.3) was found. Conclusion: The current study concludes that the use of Habit-forming substances, especially alcohol, tobacco chewing, and smoking, are prevalent among priests which are known risk factors for hypertension in the general population. Hence all screening/interventions applicable for these risk factors should be applied to this special population of priests.

Trajectories of Breastfeeding-Related Thoughts and Attitudes Among Low-Income Smoke-Exposed Pregnant Women: A Latent Class Growth Analysis.

Psychosocial predictors of breastfeeding and changes in those factors during pregnancy, along with the relationship of those changes with both breastfeeding and smoke use and exposure, are not well explored. The aim of this study was to identify distinct trajectories of psychosocial determinants of breastfeeding and smoking in pregnant women. We used a longitudinal study design and data from a randomized controlled trial conducted among smoke-exposed pregnant women and their infants. Participants were recruited early in pregnancy and were surveyed at ≤ 16 and 32 weeks gestation, delivery, 3 and 6 months postpartum for breastfeeding intentions, initiation, continuation, and smoke use and exposure. Psychosocial variables associated with breastfeeding were measured at baseline and 32 weeks gestation using the Mitra index, a structured questionnaire that assesses barriers and facilitators of breastfeeding intentions. Latent class growth analysis was performed using Mitra scores to identify distinct subgroups of participants with different trajectories. Sociodemographic characteristics, breastfeeding, and tobacco smoke use and exposure were compared across classes. Three or four trajectories were identified for each of the six Mitra scores. Trajectories for all Mitra scores were associated with breastfeeding intention and initiation. Overall, Mitra, knowledge, self-efficacy, social support, and time barrier classes all differed by tobacco smoke use or exposure. Trajectories of breastfeeding knowledge, self-efficacy, social support, and time to breastfeed/social barriers are associated with tobacco smoke use and exposure during pregnancy. Encouragement to breastfeed and to cease and avoid tobacco smoke should start early in pregnancy, focusing on these determinants to improve health outcomes.

Theoretically framing views of people who smoke in understanding what might work to support smoking cessation in coastal communities: adapting the TIDieR checklist to qualitative analysis for complex intervention development

IntroductionPeople living in coastal communities have some of the worst health outcomes in the UK, driven in part by high smoking rates. Deprived coastal communities include socially disadvantaged groups that struggle to access traditional stop smoking services. The study aimed to seek the views of people who smoke living in coastal communities, to assess the optimal smoking cessation intervention for this population. In addition, the Template for Intervention Description Replication (TIDieR) checklist was adapted as an analytical framework for qualitative data to inform intervention design.MethodsCurrent or recent ex-smokers (n = 25) were recruited to participate in qualitative interviews from a range of community locations in a deprived English seaside town. A thematic analysis of the interview data was undertaken adapting the TIDieR framework. This analysis was triangulated with relevant literature and notes from stakeholder meetings and observations to map onto the TIDieR checklist to describe the optimal intervention.ResultsBarriers to quitting smoking in the target population included low motivation to quit, high anxiety/boredom, normalisation of smoking and widespread illicit tobacco use. There was broad support for combining behavioural support, e-cigarettes and financial incentives, with a strong preference for the intervention to be delivered opportunistically and locally within (non-healthcare) community settings, in a non-pressurising manner, ideally by a community worker specially trained to give stop smoking support.ConclusionsAn intensive community-based smoking cessation intervention was acceptable to the target population. Adapting the TIDieR checklist as a deductive qualitative analytical framework offered a systematic approach to intervention development. Combined with other intervention development activities, this ensured that the intervention design process was transparent and the proposed intervention was well defined. It is recommended that prior to intervention development researchers speak to members of the target population who may give valuable insight into the optimal intervention.

Are educational aspirations associated with susceptibility to smoking, e-cigarette use, and smokeless tobacco use in adolescence?

The early socio-economic differences in smoking build on the interplay between individual-, family-, peer-, and school-related factors. The present study aimed to add knowledge to this by examining susceptibility to smoking (S-SM), electronic cigarette (e-cigarette) use (S-EC), and smokeless tobacco (snus) use (S-SN) by educational aspirations in a country with advanced tobacco control policies. National cross-sectional School Health Promotion study survey was conducted among 8.-9. grade students (av. 15-year-olds) in 2017 with no prior smoking (n = 47589), e-cigarette use (n = 49382), or snus use (n = 53335). Gender-stratified, age-adjusted multilevel logistic regression analyses with S-SM, S-EC, and S-SN were considered as outcomes and student- and school-level (aggregated) factors were considered as independent variables. The highest prevalence was observed for S-EC (girls 29%, boys 35%), followed by S-SM (16%, 15%) and S-SN (10%, 16%). Compared to those planning for general upper secondary education, S-SM was the highest for those without educational aspirations (OR = 1.20, 95% CI = 1.04-1.40), S-EC for those planning for vocational education [1.15 (1.05-1.25)], and S-SN for those planning for extra year/discontinuation [1.65 (1.04-2.60)] among girls. Among boys, both S-SM [1.37 (1.23-1.52)] and S-EC [1.19 (1.09-1.29)] were the highest among those planning for vocational education, with no clear associations with S-SN. Current other tobacco/e-cigarette use [OR range 1.27-8.87], positive attitude towards product use in one's age group [3.55-6.63], and liking school [0.58-0.68] consistently associated with susceptibility. Students not planning for academically oriented education had higher susceptibility to different nicotine products. High S-EC warrants monitoring to strengthen policy evaluation and prevention.

Current Pharmacotherapies for Smoking Cessation and Promising Emerging Drugs.

Pharmacotherapy is commonly used during quit attempts and has shown an increase in the likelihood of achieving abstinence. However, with established pharmacotherapies, abstinence rates following a quit attempt remain low, and relapse is common. This review aims to investigate the efficacy and harm profiles of current and emerging pharmacotherapies. Literature review of current and emerging pharmacotherapies for smoking cessation and tobacco use disorder. Emerging pharmacotherapies include new formulations of existing therapies, drug repurposing and some new treatments. New treatments are welcome and may incorporate different mechanisms of action or different safety and tolerability profiles compared to existing treatments. However, emerging pharmacotherapies have yet to demonstrate greater efficacy compared to existing treatments. The emergence of Electronic Nicotine Delivery Systems (ENDS) or 'vaping' is a feature of the current debate around tobacco use disorder. ENDS appear to facilitate switching but not quitting and are controversial as a harm minimisation strategy. Studies included a broad range of therapies and trial designs that should be compared with their differences taken into consideration. Strategies to successfully quit smoking vary between individuals and may extend beyond pharmacotherapy and involve complex psychosocial factors and pathways.

Presentation, management, and early outcomes of young acute coronary syndrome patients- analysis of 23,560 South Asian patients from 2012 to 2021

BackgroundThere is dearth of literature addressing early outcomes of acute coronary syndrome (ACS) among young patients, particularly South Asians descent who are predisposed to premature coronary artery disease (CAD). Therefore, we compared presentation, management, and early outcomes of young vs. old ACS patients and explored predictors of in-hospital mortality.MethodsWe extracted data of 23,560 ACS patients who presented at Tabba Heart Institute, Karachi, Pakistan, from July 2012-June 2020, from the Chest pain-MI-Registry™. We categorized data into young ≤ 45 and old ACS patients > 45 years. Chi-sq/Fischer exact tests were used to assess the difference between presentation, disease management, and in-hospital mortality between both groups. Logistic regression was used to determine odds ratio along with 95% confidence interval of factors associated with early mortality.ResultsThe younger patients were 12.2% and women 23.5%. The prevalence of dyslipidemia (34.5% vs. 22.4%), diabetes (52.1% vs. 27.4%), and hypertension (68.3% vs. 42.9%) was higher in older patients. Family history of premature CAD (18.1% vs. 32.7%), smoking (40.0% vs. 22.9%), and smokeless tobacco use (6.5% vs. 8.4%) were lower in older patients compared to younger ones. Younger patients were more likely to present with STEMI (33.2% vs. 45%). The median symptom-to-door time was 125 min longer (p-value < 0.01) in the young patients compared to the older age group. In-hospital mortality (4.3% vs. 1.7%), cardiac arrest (1.9% vs. 0.7%), cardiogenic shock (1.9% vs. 0.9%), and heart failure (1% vs. 0.6%) were more common in older patients. After adjusting for other factors, younger age (AOR 0.6, 95% CI 1.5–3.7) had significantly lesser odds of in-hospital mortality. Other factors associated with early mortality included women, family history of premature CAD, STEMI, Killip class III and IV, coronary angiography, revascularization, CABG, and use of aspirin and beta blockers within the first 24 h.ConclusionWe found every tenth ACS patient was younger than 45 years of age despite a lesser number of comorbidities such as hypertension and diabetes. Overall, the in-hospital prognosis of young patients was more favorable than that of older patients. The study emphasizes the need for tailored primary prevention programs for ACS, considering the varying risks among different age groups.

The association between smoking and smokeless tobacco use with dental caries among Pakistani patients

BackgroundTobacco use is widely recognised as a significant risk factor for oral cancer and periodontal diseases. However, the relationship between various types of tobacco use and dental caries has been inconsistent. This study aimed to determine the association between smoking and smokeless tobacco and dental caries among patients in a tertiary care hospital in Quetta, Pakistan.MethodsThis cross-sectional study was conducted from November 2020 to March 2021 among patients in a tertiary care hospital in Quetta, Pakistan. Oral examinations and interviews were performed according to the WHO Oral Health Survey basic methods (5th edition) to determine dental caries status, tobacco use, and oral health behaviours. The odds ratio and binary logistic regression were analysed to assess the association between the types (smoking tobacco, smokeless tobacco, and use of both types), duration, and frequency of tobacco use and high caries level (DMFT ≥ 5).ResultsFour hundred participants aged 18–65 were included, and 67.8% were tobacco users. Use of both smoking and smokeless tobacco (aOR = 14.7, 95%CI = 1.87–115.96, p = 0.011), smokeless tobacco only (aOR = 5.90, 95%CI = 1.89–18.37, p = 0.002), and smoking only (aOR = 2.18, 95%CI = 1.23–3.88, p = 0.008) were associated with significantly increased risk of high caries. Using tobacco for longer periods and more frequently daily also significantly increases the risk of high caries.ConclusionSmoking and smokeless tobacco are significantly associated with high dental caries after adjusting for other factors. Due to the high severity of dental caries and the high prevalence of tobacco use among Pakistani patients in this study, it is highly recommended to strengthen policies aimed at reducing tobacco usage, including smokeless forms.

Smokers with higher positive or negative urgency have lower rates of smoking cessation success 12 months after a quit attempt

Impulsivity dimensions have been shown to be associated with smoking status and tobacco use disorder severity. However, it is important to determine the specific impulsivity traits associated with smoking relapse. This study aimed at investigating the associations between impulsivity traits and smoking cessation success among adult smokers at 12 months after a quit attempt. Participants were 68 adult smokers enrolled in a 3-month course of simvastatine or placebo associated with behavioral cessation support, with a 9-month follow-up (ADDICSTATINE study). They were classified in 3 groups according to smoking status: abstinent, reduction ≥ 50%baseline or reduction < 50%baseline at 3 and 12 months. Impulsivity traits were assessed using the UPPS-P-scale. At 12 months, abstainers and participants who reduced smoking by 50% or more had significantly lower scores in negative and positive urgency compared to participants who reduced smoking by less than 50% (p = 0.011 and 0.0059). These urgency traits scores at 12 months were significantly and negatively correlated with smoking reduction at 12 months (p = 0.017 and 0.0012). These impulsivity traits were also associated with the smoking cessation success at 3 months. Patients who were abstinent at 3 months had also lower negative and positive urgency (p = 0.017 and 0.0039). Smoking cessation success at 3 and 12 months were not associated with the other impulsivity traits, sensation seeking, lack of premeditation or perseverance. Our findings suggest that positive and negative urgency are associated with smoking cessation success. Proposing better tailored-based-treatment targeting these impulsivity traits in combination with conventional treatment may help improving smoking treatment success.

Abstract 2152: Evaluating beliefs and perceived competence about tobacco cancer prevention practices in Texas local mental health authorities

Abstract Tobacco use is causally associated with 18 cancers and is a leading cause of preventable death. Individuals experiencing mental illness use tobacco at an elevated rate and consequently suffer from greater cancer-related morbidity and mortality. Unfortunately, local mental health authorities (LMHAs), a common setting to receive mental health services, do not prioritize tobacco dependence treatment despite robust evidence that tobacco cessation can enhance mental health in addition to reducing cancer incidence. Beliefs (Health Belief Model) and competence (Self Determination Theory) both play an integral role in shaping behavior. Consequently, this study examined employee and provider tobacco-related beliefs and competence in LMHAs to contextualize their tobacco intervention practices. The frequency of beliefs and competence related to provision of evidence-based tobacco cessation care was collected by e-survey from organizational representatives of 30 of the 39 LMHAs in Texas in 2021. Queries included if respondents agreed that patients should concurrently quit drugs/alcohol and tobacco (N=30 employees) and if they believed patients want to quit cigarette and non-cigarette (i.e., other) tobacco products (n=16 direct service providers). Providers were also asked if they thought that they had the competence to help patients quit smoking and other tobacco use, if they could tailor cessation treatment to patient needs, and about their intervention practices. Only 40% of LMHA representatives endorsed that patients should quit tobacco at the same time as other drugs. Furthermore, only 50% of providers believed that patients want to quit smoking and other tobacco use, respectively. About 70% of providers believed that they have the skills to help patients quit smoking and other tobacco use, respectively, but only 56% reported that they can tailor treatment. Finally, only 56% and 38% of providers recommend that patients stop smoking or other tobacco use, respectively, with 25% recommending smokers switch to vapes or smokeless tobacco products. Contrary to LMHA employee and provider beliefs, research indicates that most patients want to quit tobacco use and that concurrent tobacco use treatment can enhance patient sobriety for non-nicotine substance use disorders. Results demonstrate high levels of misinformation on concurrent tobacco and substance use treatment in LMHAs, which can subvert the provision of evidence-based cessation care. Educational interventions are needed to shift these beliefs, increase competence, and increase tobacco use intervention provision. This will not only help to address cancer disparities among patients but also improve mental health- a critical goal of LMHAs. Future research should investigate how to target tobacco-related beliefs, competence, and intervention behavior in LMHAs to broaden the reach of cancer prevention strategies.

An Experimental Study to Evaluate the Effectiveness of PTP on Attitude of Adolescents Regarding Effects of Smoking and Smokeless Tobacco Use and it’s Health Hazards Among Students in Selected High School in Dewas

Adolescence represents a period of substantial growth and potential, yet it is simultaneously a phase of considerable vulnerability. Many young people during this stage encounter temptations to engage in behaviors such as alcohol and drug use, smoking, and early sexual activity, which can lead to a higher likelihood of intentional harm and sexually transmitted infections. In the university setting, a deeper understanding and observation of the impact of tobacco-related illnesses, combined with exposure to more rigorous anti-smoking environments, can gradually lead to behavioral shifts regarding tobacco consumption among young people. This study was conducted to assess the attitude level of adolescent regarding effect of smoking and Smokeless Tobacco use and it’s Health Hazards and find out the association between attitudes level of adolescents with selected demographic variable. Method: The sample was selected for the study includes 60 college students. Evaluate approach and simple random sampling method was used to select the sample. The reliability of the tool was established and the data was collected by using structured knowledge questionnaire, based on demographic data, 20 items on attitude scale. Likert scale was used to assess the attitude score. Result: Adolescents showed that 18.3% of Adolescents had a positive attitude in the pre-test. And 65.0% of them have a moderately favorable Attitude and 16.7% has an Un-favorable attitude. In the post-test, 73.30% of students had an adequate favorable attitude, and 26.7% of them had a moderately favorable attitude and none of them have an unfavorable attitude. The contrast between pre-test and post-test attitude was computed by utilizing student paired t-test and the value is t=17.56 with the degree of freedom df=58 at p&lt;0.05 level of significance. Conclusion: Planned teaching Programme was found to be a very effective method of enhancing favourable attitude regarding effects of smoking and smokeless tobacco .......

Positive Association Between Family and Teachers' Tobacco Use on the Smoking Behaviors of Iraqi Adolescents Attending Schools - A Cross Sectional Study Using the Global Youth Tobacco Survey.

Objective: Adolescent tobacco and E-cigarette use have been rising globally in the past decade. Iraq's post-war conflict and economic crises posed psychosocial and mental health trauma, contributing to increased vulnerability to drug and substance use among adolescents. This study looks to assess the potential relationship between current tobacco and E-cigarette smoking and exposure to smoking at home and school among Iraqi adolescents attending schools. Methods: Data analysis for the 2019 Iraq Global Youth Tobacco Survey, a cross-sectional study completed by 2560 Iraqi adolescents aged 11 to 17 years old was conducted. The survey tool which includes demographic, tobacco use, knowledge and attitudes towards tobacco use questions is anonymous and self-administered using paper-based bubble sheets that are scannable. Current tobacco and E-cigarette use (defined as past 30-days) were the main outcomes. Univariate and multivariate logistic regression models were used to assess the relationship between the main outcomes and the following variables: participants' demographics, exposure to smoking, attitude and knowledge scores. Results: Current tobacco and E-cigarette smoking prevalence among Iraqi adolescents attending school were 14.9% (95% CI: 13.5%-16.4%) and 9.7% (95% CI: 8.6%-11.0%), respectively. Exposure to smoking at home was high among fathers (39.1%), mothers (13.9%), siblings smoke (23.9%), other individuals smoke (56.1%). The percentages of students who witnessed people smoking within school premises was 45.7% and observed teachers smoking in schools was 57.6%. The current use of tobacco smoking among Iraqi adolescents was significantly and positively associated with exposure to smoking by the father (AOR = 1.39; 95% CI: 1.05-1.85), mother (AOR = 1.84; 95% CI: 1.30-2.60), sibling (AOR = 3.50; 95% CI: 2.62-4.67), teacher (AOR = 1.48; 95% CI: 1.10-1.98), and people in school (AOR = 1.99; 95% CI: 1.57-2.53). Similarly, the current use of E-cigarettes was significantly associated with father smoking (AOR = 2.02; 95% CI: 1.29-3.16), sibling smoking (AOR = 3.09; 95% CI: 2.04-4.67), and people smoking in school (AOR2.02; 95% CI: 1.39-2.95). Conclusion: Stricter policies need to be enforced to ensure safer school environments that do not expose adolescents to smoking habits of teachers or other students.

Association Between Neighborhood Deprivation in Early Pregnancy and Gestational Diabetes Mellitus.

To evaluate whether having a pregnancy in a deprived neighborhood was associated with an increased risk of gestational diabetes mellitus (GDM) compared with having a pregnancy in the least-deprived neighborhoods. This was a retrospective observational cohort study of pregnant individuals within Kaiser Permanente Northern California from 2011 to 2018 with residential history from prepregnancy through 24 weeks of gestation and clinical data from prepregnancy through delivery. The primary outcome was a diagnosis of GDM. Neighborhood deprivation was characterized with an index aggregating multiple indicators of Census tract-level sociodemographic information. Mediation analysis using inverse odds ratio weighting estimated the mediation effects of prepregnancy body mass index (BMI), gestational weight gain, smoking tobacco, and illegal drug use before GDM diagnosis. Overall, 214,375 pregnant individuals were included, and 11.3% had a diagnosis of GDM. Gestational diabetes prevalence increased with neighborhood deprivation from 10.0% in the lowest Neighborhood Deprivation Index quintile to 12.7% in the highest quintile. Compared with pregnant individuals in the least deprived neighborhoods (quintile 1), pregnant individuals in quintiles 2-5 had elevated risk of GDM (relative risk [95% CI]) when adjusted for maternal age, parity, insurance type, and residential history (quintile 2, 1.17 [1.10-1.23]; quintile 3, 1.38 [1.30-1.46]; quintile 4, 1.54 [1.45-1.63]; quintile 5, 1.71 [1.62-1.82]). There was a dose-response relationship between relative risk of GDM and increasing quintile of neighborhood deprivation ( P for trend <.001). Prepregnancy BMI mediated 45.8% (95% CI, 40.9-50.7%) of the association. Other potential mediators were found to mediate a small if not negligible proportion of this association (2.4-3.6%). Neighborhood deprivation was associated with GDM, and a considerable proportion of this relationship was mediated by prepregnancy BMI.

Smoking Policies of Outpatient and Residential Substance Use Disorder Treatment Facilities in the United States.

Tobacco use is associated with morbidity and mortality. Many individuals who present to treatment facilities with substance use disorders (SUDs) other than tobacco use disorder also smoke cigarettes or have a concomitant tobacco use disorder. Despite high rates of smoking among those with an SUD, and numerous demonstrated benefits of comprehensive SUD treatment for tobacco use in addition to co-occurring SUDs, not all facilities address the treatment of comorbid tobacco use disorder. In addition, facilities vary widely in terms of tobacco use policies on campus. This study examined SUD facility smoking policies in a national sample of N = 16,623 SUD treatment providers in the United States in 2021. Most facilities with outpatient treatment (52.1%) and facilities with residential treatment (67.8%) had a smoking policy that permitted smoking in designated outdoor area(s). A multinomial logistic regression model found that among facilities with outpatient treatment (n = 13,778), those located in a state with laws requiring tobacco free grounds at SUD facilities, those with tobacco screening/education/counseling services, and those with nicotine pharmacotherapy were less likely to have an unrestrictive tobacco smoking policy. Among facilities with residential treatment (n = 3449), those with tobacco screening/education/counseling services were less likely to have an unrestrictive tobacco smoking policy. There is variability in smoking policies and tobacco use treatment options in SUD treatment facilities across the United States. Since tobacco use is associated with negative biomedical outcomes, more should be done to ensure that SUD treatment also focuses on reducing the harms of tobacco use.
