RESUMEN
INTRODUCTION: Secondhand tobacco smoke (SHS) exposure causes diseases and death in adults and children. Evidence indicates that most SHS exposures occur at home and in the workplace. Therefore, home is a major place where adults and children can be effectively protected from SHS. This study examined the magnitude of SHS exposure at home and associated factors in eight sub-Saharan African countries. AIMS AND METHODS: We analyzed 2012-2018 Global Adult Tobacco Survey data for Botswana, Cameroon, Ethiopia, Kenya, Nigeria, Senegal, Tanzania, and Uganda. We computed prevalence estimates of self-reported monthly SHS exposure at home reported as anyone smoking inside their home daily, weekly, or monthly. We calculated SHS exposure at home prevalence and applied multivariable logistic regression models to identify related factors. RESULTS: Overall median prevalence of SHS exposure at home was 13.8% in the eight countries; ranging from 6.6% (95% CI: 5.7%, 7.6%) in Nigeria to 21.6% (95% CI: 19.4%, 24.0%) in Senegal. In multivariable analysis across the countries, SHS exposure at home was associated with living with a smoker, ranging from an adjusted odds ratio (AOR) of 4.6 (95% CI: 3.6, 5.8) in Botswana to 27.6 (95% CI: 20.1, 37.8) in Nigeria. SHS exposure at home was significantly associated with lower education attainment (Kenya and Ethiopia), and lower wealth index (Uganda, Senegal, and Botswana). CONCLUSIONS: SHS exposure in homes was associated with the presence of a smoker in the home and lower socioeconomic status.

Background: Electronic nicotine delivery systems (ENDS) use among adolescents in the United States (U.S.) has surpassed conventional tobacco products (CTPs), including cigarettes. Increasingly, ENDS are used concurrently with CTPs and substances such as cannabis. However, few studies involve Central Appalachia, a region with historically high rates of tobacco and other substance use. Objective: To examine prevalence of concurrent use of ENDS and cannabis among school-going adolescents in Appalachian Tennessee and delineate associations between ENDS use and substance-related risk behavior (cannabis use), social relations (peer use), and school-related risk behavior (academic performance). Methods: Data were obtained from a survey conducted with youth aged 13-17 years in 2018 in a county in Appalachian Tennessee (n = 280). A multivariable logistic regression model was fit to evaluate associations between ENDS and cannabis use, and other factors. Results: Overall, lifetime ENDS and cannabis prevalence estimates were 31.1% and 18.6%, respectively. Lifetime ENDS users had increased odds of also being lifetime cannabis users [OR = 9.22, 95% confidence interval (CI): 3.44-24.75]. Lifetime ENDS users had increased odds of reporting ENDS use among peers [OR = 12.11; 95% CI: 5.40-27.12] and lower academic performance (OR associated with mostly C or D vs. A grades was 4.28, 95% CI: 1.68-10.90). Conclusion: This study found an association between ENDS and cannabis use among adolescents in Appalachian Tennessee exists. Additionally, peer use and academic performance were associated with ENDS use. The findings have implications for public health intervention planning to address not only ENDS but also substance use among Appalachian youth.

BACKGROUND: Environmental exposures acting through different mechanisms have been linked with a number of cancers. Perfluoroalkyl chemicals (PFCs) are endocrine disrupting chemicals affecting estrogen homeostasis. OBJECTIVES: We examined the association between PFCs and a group of estrogen related cancers and explored if increased non-occupational exposure was associated with increased odds of developing these cancers. We also explored which of these chemical exposures was more correlated with each cancer. METHODS: Using data from the National Health and Nutrition Examination Survey (NHANES), we selected participants ≥ 20 years of age. Our outcome variable was presence or absence of breast, prostate, ovarian and uterine cancer (yes/no); our exposure variables were serum PFCs. Logistic regression models were used in investigating the association between PFCs and cancer types and between quartiles of PFCs exposure concentrations and presence or absence of cancer while adjusting for covariates. Discriminant analysis was used to assess the correlation between individual PFCs compounds and individual cancer types. RESULTS: PFCs were associated with increased odds of ovarian cancer; PFOA: 1.02(1.01, 1.02), PFOS: 1.01 (1.012, 1.013), PFHS 1.031 (1.030, 1.033), PFDE: 1.29(1.27, 1.30) and increased odds of breast cancer; PFOA: 1.089(1.089, 1.09), PFOS: 1.011(1.011, 1.011), PFNA: 1.031(1.030, 1.033), PFHS: 1.02 (1.02, 1.02), PFDE: 1.19(1.18, 1.19). PFCs were not associated with increased odds of prostate or uterine cancers. Comparing the odds in quartile 4 to quartile 1 for ovarian cancer, PFOA: 1.77(1.75,1.79), PFOS: 2.25(2.22, 2.28), PFHS: 1.86(1.84, 1.88), PFDE: 2.11(2.09, 2.14). For breast cancer, PFOA: 2.30(2.28, 2.31), PFOS: 1.47(1.46, 1.48), PFNA: 1.04(1.03, 1.05), PFHS:7.07(6.97,7.17), PFDE: 1.38(1.37, 1.39). PFOA was more correlated with breast cancer (0.7) and PFHS was more correlated with ovarian cancer (0.9). DISCUSSION: PFCs were associated with increased odds of ovarian and breast cancers with a positive dose-response relationship. PFOA was more correlated with breast cancer and PFHS more with ovarian cancer.

OBJECTIVES: This study aimed to examine the association of Per and Polyfluoroalkyl substances (PFAS) and markers of chronic inflammation and oxidative stress. METHODS: Using data (n = 6652) from the National Health and Nutrition Examination Survey (NHANES) 2005-2012, generalized linear models were used to examine the association between PFAS and inflammatory (ferritin, alkaline phosphatase, C-reactive protein, absolute neutrophil count and lymphocyte count) and oxidative stress (serum bilirubin, albumin and iron) per unit exposure to PFAS while adjusting for covariates. Study participants were those ≥20 years of age. Outcome variables were markers of chronic inflammation and oxidative stress and exposure variables were PFAS. RESULLTS: Percentage change in Perfluorohexane sulfonic acid (PFHxS), Perfluorononanoic acid (PFNA), Perfluorooctanoic acid (PFOA), Perfluorooctane sulfonic acid (PFOS), and Perfluorodecanoic acid (PFDA) were all significantly associated with percentage increases in lymphocyte counts, beta (95% confidence interval); 0.04(0.02,0.05), 0.04(0.02,0.05), 0.05(0.03, 0.07), 0.04(0.03,0.05), 0.03(0.13,1.23) and with percentage increases in serum iron 0.07(0.05,0.09), 0.04(0.02,0.07), 0.10(0.07,0.12), 0.05(0.03,0.07), 0.04(0.02,0.06) and increased serum albumin 0.02(0.02,0.02), 0.02(0.02,0.03), 0.03(0.03,0.04), 0.02(0.017, 0.025), 0.01 (0.01, 0.05). Only PFHxS, PFNA, PFOA and PFOS were associated with percentage increases in serum total bilirubin 0.04(0.03,0.05), 0.02(0.00,0.03), 0.06(0.04,0.08), 0.03(0.02,0.05). Similar results were obtained for categorical quintile analysis with PFOA showing a significant trend (P < 0.001) with lymphocyte count, serum iron, serum total bilirubin and serum albumin. Trend for neutrophil count was not significant (p = 0.183). CONCLUSION: Per and Polyfluoroalkyl substances are associated with markers of chronic inflammation and oxidative stress. Increased exposure leads to increase in serum concentration of these markers meaning these chemicals are associated with both chronic inflammation and oxidative stress.

BACKGROUND: Tobacco use is associated with exacerbation of tuberculosis (TB) and poor TB treatment outcomes. Integrating tobacco use cessation within TB treatment could improve healing among TB patients. The aim was to explore perceptions of health workers on where and how to integrate tobacco use cessation services into TB treatment programs in Uganda. METHODS: Between March and April 2019, nine focus group discussions (FGDs) and eight key informant interviews were conducted among health workers attending to patients with tuberculosis on a routine basis in nine facilities from the central, eastern, northern and western parts of Uganda. These facilities were high volume health centres, general hospitals and referral hospitals. The FGD sessions and interviews were tape recorded, transcribed verbatim and analysed using content analysis and the Chronic Care Model as a framework. RESULTS: Respondents highlighted that just like TB prevention starts in the community and TB treatment goes beyond health facility stay, integration of tobacco cessation should be started when people are still healthy and extended to those who have been healed as they go back to communities. There was need to coordinate with different organizations like peers, the media and TB treatment supporters. TB patients needed regular follow up and self-management support for both TB and tobacco cessation. Patients needed to be empowered to know their condition and their caretakers needed to be involved. Effective referral between primary health facilities and specialist facilities was needed. Clinical information systems should identify relevant people for proactive care and follow up. In order to achieve effective integration, the health system needed to be strengthened especially health worker training and provision of more space in some of the facilities. CONCLUSIONS: Tobacco cessation activities should be provided in a continuum starting in the community before the TB patients get to hospital, during the patients' interface with hospital treatment and be given in the community after TB patients have been discharged. This requires collaboration between those who carry out health education in communities, the TB treatment supporters and the health workers who treat patients in health facilities.

PURPOSE OF REVIEW: Electronic cigarettes (e-cigarettes) are gaining rapid popularity among all age groups, especially among youth. They have evolved into technologically advanced devices capable of delivering nicotine concentration and other substances. In addition to nicotine, e-cigarettes' constituents possess variety of toxic chemicals that have adverse effects on human body. RECENT FINDINGS: In recent years, steady downward trend in tobacco usage has been observed; however, e-cigarette use is on upward trend. E-cigarettes are advertised as "safer" alternatives to conventional smoking and as an aid to smoking cessation. Emerging studies have, however, shown that e-cigarettes have harmful effects on the cardiovascular system and that most of the e-cigarette users are dual users, concurrently using e-cigarettes and smoking conventional cigarettes. Despite a gap in clinical studies and randomized trials analyzing adverse cardiovascular effects of e-cigarette use, the existing literature supports that different constituents of e-cigarettes such as nicotine, carbonyls, and particulate matters carry potential risk for cardiovascular diseases (CVD) on its users.

This study aimed to assess the prevalence of and factors associated with tobacco use among patients living with HIV/HCV co-infection. Patient reported outcomes (PROs) were analyzed of patients living with HIV/HCV co-infection (n = 313) who presented for clinical evaluation and treatment of HCV between 2013 and 2017 at a university-affiliated HIV/HCV Co-infection Clinic. The prevalence of tobacco use in patients living with HIV/HCV co-infection was 48%. Compared to non-smokers, a higher proportion of tobacco smokers had substance use disorders and concurrent alcohol and substance use. In the multivariate analysis, concurrent alcohol and substance use was positively associated with tobacco use. The findings suggest clinical interventions are urgently needed to reduce tobacco use among patients living with HIV/HCV co-infection-a doubly-vulnerable immunocompromised population. Otherwise, failed efforts to dedicate resources and targeted behavioral interventions for this respective population will inhibit survival-especially considering the recent and evolving COVID-19 pandemic.

Smokefree environment created by smokefree policies is associated with smoking reduction; however, there is paucity of literature on the relationship between smokefree home rules and smoking intensity in low-and-middle income countries (LMICs), and how smokefree policy affects smoking behavior of smokers at different stages of smoking cessation. This study examined the relationship between smokefree home rules and average number of cigarettes smoked per day (CPD) among daily smokers at different stages of the transtheoretical model (TTM) of change. Data from 18,718 current daily cigarette smokers from the Global Adult Tobacco Survey (GATS) conducted from 2011 to 2017 in 20 LMICs were analyzed. Weighted multivariable linear regression analyses were conducted using the log of CPD as the outcome variable with smokefree home rules as the exposure variable, controlling for selected covariates. Approximately 15% of the participants were in precontemplation, 5% were in preparation, 15% lived in partial smokefree homes, and 30% lived in complete smokefree homes. The average number of CPD was 12.3, 12.0, and 10.6 among participants living in homes where smoking was allowed, partial smokefree homes, and complete smokefree homes, respectively. Compared to living in homes where smoking was allowed, living in complete smokefree homes were associated with 22.5% (95%CI = 18.4%-26.5%), 17.9% (95%CI = 8.4%-27.3%), and 29.3% (95% CI = 17.1%-41.5%) fewer CPD among participants in precontemplation, contemplation, and preparation stages, respectively. These findings suggest that complete smokefree home policy will benefit smokers in LMICs irrespective of their intention to quit smoking in addition to protecting non-smokers from secondhand smoke exposure.

Introduction: This study aimed to examine the association of smoking status with homocysteine levels and to determine whether the association is modified by oestradiol or cholesterol.Methods: Data (N = 4580) were obtained from National Health and Nutrition Examination Survey 2003-2004 with analysis done in 2018 on adults aged ≥20 years. The outcome was homocysteine; smoking status was the exposure variable and categorized as current, former or never smoker. Generalized linear models were used to examine the associations between smoking status and homocysteine levels, while assessing the impact of oestradiol and cholesterol.Results: After adjusting for age, sex, ethnicity, education and income level, homocysteine levels did differ by smoking status ((current smokers versus never smokers: ß: 0.18 CI: 0.00, 0.36), (former smokers: ß: 0.10 CI: -0.09, 0.28)). The addition of oestradiol as an interaction term in adjusted models was associated with a 16.6% increase in homocysteine levels when compared to models without the interaction term. Oestradiol but not cholesterol did moderate the association between smoking status and homocysteine levels.Discussion and conclusions: Homocysteine levels did differ across smoking status after adjusting for confounders. Oestradiol did moderate the relationship between homocysteine and smoking status.

INTRODUCTION: There is no known safe level of secondhand smoke exposure; yet, less than 30% of the global population is covered by comprehensive smoke-free policies as of 2016 and there are few smoke-free policies in sub-Saharan Africa (SSA). This study examines the support for smoke-free public places in SSA and delineates their correlates. METHODS: Data collected through the Global Adult Tobacco Survey (2012-2017) were analyzed using SAS for descriptive and multivariable analyses, with a significance level set at p < .05. RESULTS: No SSA country had comprehensive smoke-free policies, defined as a prohibition of smoking in eight public places. In the four countries whose Global Adult Tobacco Survey data were analyzed (Nigeria, Cameroon, Kenya, and Uganda), support for the prohibition of smoking in public places was over 90% in all eight public places except bars. Support for smoking prohibition in bars was 65.8%, 81.1%, 81.4%, and 91.0% in Nigeria, Cameroon, Kenya, and Uganda, respectively. Factors associated with support for smoke-free bars differed across the four countries, but in all countries, current smokers had decreased odds of support for smoke-free bars. Knowledge of secondhand smoke harm and living in smoke-free homes were associated with increased odds of support for smoke-free bars in all countries except Kenya. CONCLUSION: The high support for smoke-free public places should inform the efforts of the public health community and policymakers in these four SSA countries toward meeting their obligations of Article 8 of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC). IMPLICATIONS: Much of the population in SSA is not protected by comprehensive smoke-free policies. It was found that the overwhelming majority of adults in four large countries in SSA support the prohibition of smoking in public places and that knowledge of the health dangers of smoking and exposure to secondhand smoke and home smoking rules increased support for the prohibition. High support for the prohibition of smoking in these four SSA countries suggests tobacco control proponents should advocate for comprehensive smoke-free policies.

BACKGROUND: Previous studies show a positive association between household wealth and overweight in sub-Saharan African (SSA) countries; however, the manner in which this relationship differs in the presence of educational attainment has not been well-established. This study examined the multiplicative effect modification of educational attainment on the association between middle-income and rich household wealth and overweight status among adult females in 22 SSA countries. We hypothesized that household wealth was associated with a greater likelihood of being overweight among middle income and rich women with lower levels of educational attainment compared to those with higher levels of educational attainment. METHODS: Demographic and Health Survey (DHS) data from 2006 to 2016 for women aged 18-49 years in SSA countries were used for the study. Overweight was defined as a body mass index (BMI) ≥ 25 kg/m2. Household wealth index tertile was the exposure and educational attainment, the effect modifier. Potential confounders included age, ethnicity, place of residence, and parity. Descriptive analysis was conducted, and separate logistic regression models were fitted for each of the 22 SSA countries to compute measures of effect modification and 95% confidence intervals. Analysis of credibility (AnCred) methods were applied to assess the intrinsic credibility of the study findings and guide statistical inference. RESULTS: The prevalence of overweight ranged from 12.6% in Chad to 56.6% in Swaziland. Eighteen of the 22 SSA countries had measures of effect modification below one in at least one wealth tertile. This included eight of the 12 low-income countries and all 10 middle income countries. This implied that the odds of overweight were greater among middle-income and rich women with lower levels of educational attainment than those with higher educational attainment. On the basis of the AnCred analysis, it was found that the majority of the study findings across the region provided some support for the study hypothesis. CONCLUSIONS: Women in higher wealth strata and with lower levels of educational attainment appear to be more vulnerable to overweight compared to those in the same wealth strata but with higher levels of educational attainment in most low- and middle- income SSA countries.

OBJECTIVE: The central Appalachian region of the United States is disproportionately burdened with cardiovascular disease (CVD); however, the level of literacy about CVD among residents has not been well studied. This study aimed to examine the prevalence and factors of CVD health literacy (HL) among a sample of patients/caregivers, providers/professionals, and community stakeholders. METHODS: In 2018, data were collected from central Appalachian residents in six states: Kentucky, North Carolina, Ohio, Tennessee, Virginia, and West Virginia. CVD HL status was determined by assessing correct responses to five interrelated questions about basic knowledge of CVD. Multiple logistic regression analyses were used to examine the associations between potential factors and CVD HL status. RESULTS: Of the total respondents (N = 82), <50% correctly answered all 5 CVD HL questions. Multiple logistic regression analyses showed that compared with respondents with advanced college degrees, those with a college degree or less were more likely to have low HL for "typical symptom of CVD," "physical exercise and CVD," "blood pressure and CVD," and "stress and CVD." In addition, compared with respondents younger than 50 years, those 50 years and older were 3.79 times more likely to have low HL for "physical exercise and CVD." CONCLUSIONS: These results suggest the incorporation of CVD HL into CVD care and that educational attainments should be part of CVD policies and programs in the region.

Background and Aim: There is a need to improve utilization of cessation assistance in low- and middle-income countries (LMICs), and tobacco cessation research has been identified as priority in LMICs. This study evaluates the relationship between health care provider intervention and cessation assistance utilization in LMICs. Methods: Data from 13 967 participants (aged ≥15 years, 90.3% males) of the Global Adults Tobacco Survey conducted in 12 LMICs (74.3%-97.3% response rates) were analyzed with utilization of counseling/cessation clinic, WHO-recommended medications, and quitline as outcome variables. Health care provider intervention ("no intervention," only "tobacco screening," "quit advice") was the exposure variable. Weighted multiple logistic regression models were used to examine the relationship between each outcome variable and the exposure variable, adjusting for other covariates. Adjusted odds ratios (ORs) with 95% confidence intervals (CIs) are reported. Results: Approximately 52%, 8%, and 40% of participants received no intervention, only tobacco screening, and advice to quit, respectively. Overall, 0.4%, 1.9%, 3.0%, and 4.5% used quitline, WHO-recommended medications, counseling/cessation clinic, and any cessation assistance, respectively. Compared with no intervention, quit advice was associated with increased utilization of quitline (OR = 2.24, 95% CI = 1.2 to 4.4), WHO-recommended medications (OR = 1.67, 95% CI = 1.2 to 2.3), counseling/cessation clinic (OR = 4.41, 95% CI = 3.2 to 6.1), and any assistance (any of the three types) (OR = 2.80, 95% CI = 2.2 to 3.6). Conclusion: The findings of this study suggest that the incorporation of quit advice by health care providers in tobacco control programs and health care systems in LMICs could potentially improve utilization of cessation assistance to improve smoking cessation in LMICs. Implications: This first study of association between health care provider intervention and the utilization of cessation assistance in LMICs reports that there was a missed opportunity to provide quit advice to about 60% of smokers who visited a health care provider in the past year. The odds of utilization of counseling/cessation clinic, WHO-recommended medications, and quitline were significantly increased in participants who were advised to quit smoking. The results suggest that effective integration and implementation of advice to quit in tobacco control programs and the national health care systems may increase the use of cessation assistance to quit smoking.

BACKGROUND: Disparities in tobacco use exist across regions in the United States. The Central Appalachian region carries some of the very high rates of tobacco use prevalence but research on tobacco use initiation is sparse. OBJECTIVE: To investigate the intention to try tobacco and its associated factors among nonsmoking youth. METHOD: Data were obtained from school-based tobacco surveys (n = 539) conducted in 11 middle schools (6th-8th grades; aged 10-15 years) in Northeast Tennessee in 2015-2016. Nonsmoking participants without firm commitment to abstain from trying tobacco in the next year were considered to have an intention to try tobacco. The Full Information Maximum Likelihood estimation (FIML) method in Mplus was employed to conduct a multivariable logistic regression analysis to delineate correlates of intention to try tobacco. RESULTS: Overall, 20.0% of participants had intention to try tobacco. Among participants with intention to try tobacco, 53.7% owned tobacco-branded item(s), 86.1% believed that tobacco users have more friends, and 88.9% lived with tobacco users. In the adjusted logistic model, ever use of tobacco products, home smoking rules, owning tobacco-branded item(s), living with tobacco users, believing that tobacco users have more friends, and perception of easy access to tobacco products were significantly associated with intention to try tobacco (p < .02). CONCLUSION: This study suggests that individual, interpersonal, and community level factors influence intention to try tobacco in this environment where tobacco pre-emption laws impede development of local tobacco control policies and regulations. Thus, efforts should focus on tobacco use initiation preventive programs, including school-based tobacco control programs.

BACKGROUND: Non-communicable diseases (NCDs) account for over two-thirds of deaths worldwide, and global efforts to address NCDs have accelerated. Current prevention and control efforts rely primarily on individual behavior/lifestyle approaches that place the onus of responsibility for health on the individual. These approaches, however, have not stopped the increasing trend of NCDs worldwide. Thus, there is urgent need for exploring alternative approaches in order to attain the aim of reducing global premature NCDs mortality by 25% by 2025, and meeting the NCD reduction objective in the Sustainable Development Goals. DISCUSSION: We suggest the need for a structural approach to addressing the NCDs epidemic that integrates social science and public health theories. We evaluate two overarching principles (empowerment and human rights) and three social determinants of health (labor and employment, trade and industry, and macroeconomics) addressed in the 2013 Global Action Plan for the Prevention and Control of NCDs to demonstrate how a structural approach to NCDs can be incorporated into existing NCD interventions. For each area considered, theoretical considerations for structural thinking are provided and conclude with recommended actions. CONCLUSION: Achieving the global health agenda goals of reducing NCDs mortality will require a shift to a paradigm that embraces concerted efforts to address both behavioral/lifestyle factors and structural dimensions of NCDs.

E-cigarette use among youth in the United States (U.S.) continues to increase. In the rural Northeast Tennessee, where prevalence of tobacco use is higher than national and state averages, there is no literature on e-cigarette use to inform policies and programs. This study aimed to estimate the prevalence of e-cigarette use and examine association of e-cigarette use with two tobacco products among school-going adolescents. Data from 894 participants of a school-based survey conducted in 2016 in Northeast Tennessee were analyzed. Descriptive statistics and logistic regression analyses were conducted to estimate the prevalence and delineate the associations between e-cigarette use and other tobacco products. Approximately 11% of the participants currently used e-cigarettes, and 35% had ever used e-cigarettes. About 6% of the participants were current users of both e-cigarettes and cigarettes; 4% were current users of e-cigarettes and smokeless tobacco; 3% were current users of all three products, and 15% had ever tried all three products. More than one-half of current e-cigarette users (52%) also smoked cigarettes. Adjusting for covariates, current e-cigarette use was positively associated with cigarette smoking [Odds Ratio (OR) 27.32, 95% confidence interval (CI) 14.4-51.7] and smokeless tobacco use [OR 7.92, 95% CI 3.8-16.5]. E-cigarette use was more common among the high school students than cigarette and smokeless tobacco use, and a significant proportion of users either smoked cigarettes, used smokeless tobacco, or both. Thus, there is a critical need for preventive policies and programs to address dual and poly-use of these products.

OBJECTIVES: The central Appalachian region of the United States is disproportionately burdened with cardiovascular diseases (CVD) and associated risk factors; however, research to inform clinical practice and policies and programs is sparse. This study aimed to examine the association between multiple modifiable risk factors for CVD and hypertension in asymptomatic patients in central Appalachia. METHODS: Between January 2011 and December 2012, 1629 asymptomatic individuals from central Appalachia participated in screening for subclinical atherosclerosis. Participants were asked to report their hypertension status (yes/no). In addition, data on two nonmodifiable risk factors (sex, age) and five modifiable risk factors (obesity, diabetes mellitus, hypercholesterolemia, smoking, and sedentary lifestyle) were collected. Multivariable logistic regression analyses were conducted to assess association between hypertension and risk factors. RESULTS: Of the 1629 participants, approximately half (49.8%) had hypertension. Among people with hypertension, 31.4% were obese and 62.3% had hypercholesterolemia. After adjusting for sex and age, obesity and diabetes mellitus were associated with a more than twofold increased odds of having hypertension (odds ratio [OR] 2.02, confidence interval [CI] 1.57-2.60 and OR 2.30, CI 1.66-3.18, respectively). Hypercholesterolemia and sedentary lifestyle were associated with higher odds for hypertension (OR 1.26, CI 1.02-1.56 and OR 1.38, CI 1.12-1.70, respectively), compared with referent groups. Having two, three, and four to five modifiable risk factors was associated with increased odds of having hypertension by about twofold (OR 1.72, CI 1.21-2.44), 2.5-fold (OR 2.55, CI 1.74-3.74), and sixfold (OR 5.96, CI 3.42-10.41), respectively. CONCLUSIONS: This study suggests that the odds of having hypertension increases with a higher number of modifiable risk factors for CVD. As such, implementing an integrated CVD program for treating and controlling modifiable risk factors for hypertension would likely decrease the future risk of CVD.

INTRODUCTION: The risk factors for cardiovascular disease (CVD) are associated with coronary atherosclerosis and having multiple risk factors potentiates atherosclerosis. This study examined the prevalence of multiple biological and lifestyle/behavioral risk factors and their association with coronary artery calcium (CAC), a marker for subclinical coronary atherosclerosis. METHODS: This is a cross-sectional study of 1607 community-dwelling asymptomatic individuals from central Appalachia who participated in CAC screening between January 2011 and December 2012. Data on demographics (sex and age) and 7 traditional risk factors for coronary artery disease (CAD) were collected and categorized into 5 groups (0-1, 2, 3, 4, and ≥5). Prevalence of these risk factors and CAC scores (0, 1-99, 100-399, ≥400) were assessed, and the impact of the number of risk factors on CAC scores were delineated using multiple logistic regression. RESULTS: Over 98% of participants had ≥1 risk factor. While obesity, diabetes, hypertension, and family history of CAD significantly increased the odds of having CAC, CAC scores significantly increased with number of risk factors. After adjusting for demographic factors, having 3, 4, and ≥5 risk factors was significantly associated with increased odds of having higher CAC scores when compared to zero CAC score by more than one and half times [OR=1.65, CI (1.20-2.25)], two times [OR=2.32, CI (1.67-3.23)] and three times [OR=3.45, CI (2.42-4.92)], respectively. CONCLUSION: The high prevalence of multiple risk factors in the study population suggests the need for aggressive multiple risk factors interventions for primary prevention of CAD, which could address CVD health disparities.

BACKGROUND: Tobacco-free campus policy is identified as an effective means to address tobacco use on college campuses; however, the prevalence of tobacco-free policies (TFPs) in the United States remains low. This study explores college tobacco users' support for a university's TFP and tobacco-free campuses (TFCs) in general. METHODS: A standardized and structured questionnaire was administered to 790 college tobacco users recruited in a university located in a tobacco-growing region of the United States, during April-May 2011, to collect information on support for TFPs and TFCs and sociodemographic-political characteristics. Descriptive and multivariable logistic regression analyses were conducted to identify key factors associated with support for TFPs and TFCs. RESULTS: Approximately 2 of 5 tobacco users favored TFPs and TFCs. Multivariable logistic regression models showed that demographic factors were mostly not significantly associated with attitudes of the college tobacco users. Instead, while knowledge about harmful effects of exposure to secondhand tobacco smoke significantly increased support for both TFPs and TFCs, parental and peer smoking and exposure to tobacco industry promotions significantly decreased the likelihoods of support compared with respective referent groups. CONCLUSION: Study findings suggest that campus advocacy and education campaigns for campus tobacco policies to pay attention to tobacco use behavior of familial relations, tobacco industry activities, and other political determinants of tobacco users' attitudes. Thus, this study should inform national initiatives to promote TFPs nationwide such as the Tobacco-Free College Campus Initiative.

OBJECTIVES: We estimated the prevalence and determinants of secondhand smoke (SHS) exposure among nonsmoking adolescents in 9 West African countries. METHODS: We conducted a pooled analysis with nationally representative 2006 to 2009 Global Youth Tobacco Survey data. We used descriptive statistics to determine the prevalence of SHS exposure and inferential statistics using a multivariable logistic regression model to determine factors associated with SHS exposure. We investigated average marginal effect results that show the probability of SHS exposure, adjusting for all other attributes. RESULTS: SHS exposure inside the home ranged from 13.0% to 45.0%; SHS exposure outside the home ranged from 24.7% to 80.1%. Parental or peer smoking behaviors were significantly associated with higher probability of SHS exposure in all 9 countries. Knowledge of smoking harm, support for smoking bans, exposure to antismoking media messages, and receptivity of school tobacco education were significantly associated with higher SHS exposure in most countries. CONCLUSIONS: West African policymakers should adopt policies consistent with Article 8 of the World Health Organization Framework Convention on Tobacco Control and its guidelines and public health education to promote smoke-free households.
