RESUMO
OBJECTIVE: Post-COVID Conditions (or Long COVID) have been widely reported, but population-based studies exploring the relationship between its risk factors are lacking. We examined the associations between Long COVID, chronic obstructive pulmonary disease [COPD], vaccination status, and cigarette smoking. We also tested for the modifying effect of COPD status. METHODS: Data from the 2022 US nationwide Behavioral Risk Factor Surveillance System (BRFSS) were analyzed. Our primary outcome was Long COVID (Yes/No) after a positive COVID-19 diagnosis. Predictor variables were COPD, coronary heart disease (CHD), diabetes, asthma, body mass index, cigarette smoking status, and number of COVID-19 vaccinations (0-4). Weighted multivariable logistic regression models were used and adjusted for sociodemographic factors. Regression models were used to explore the modifying effects of COPD status. RESULTS: The weighted prevalence of Long COVID among survivors (N = 121,379) was 21.8% (95%CI: 21.4, 22.3), with tiredness/fatigue (26.2% [95%:25.1, 27.2]) as the most common symptom. Respondents with COPD (aOR: 1.71 [95%CI: 1.45, 2.02]), current daily smokers (aOR: 1.23 [95%CI:1.01, 1.49]), and former smokers (aOR: 1.24 [95%CI:1.12, 1.38]) (vs. never established smokers) had higher odds of Long COVID. However, respondents who had received three (aOR: 0.75 [95%CI:0.65, 0.85]) and four (aOR: 0.71 [95%CI:0.58, 0.86]) vaccine doses (vs. no vaccine) had lower odds of Long COVID. COPD had a modifying effect on the relationship between cigarette smoking and Long COVID (p-value: 0.013). CONCLUSION: Our findings underscore a complex interaction between COPD, cigarette smoking, and Long COVID. Further, COVID-19 vaccination may be protective against Long COVID.

BACKGROUND: Studies have explored the connections between tobacco use, sleep and cardiovascular disease (CVD) risks in adults, but no study has examined the link between tobacco use and sleep among adults with CVDs. This study explores the association between tobacco use (cigarette only, e-cigarette only, and dual use) and poor sleep duration among adults with CVDs. METHODS: A sample of 47,180 US adults with CVDs (myocardial infarction, coronary heart disease, or stroke) was drawn from the 2022 Behavioral Risk Factor Surveillance System (BRFSS) cross-sectional survey. Poor/inadequate sleep (< 7 h/24-hour) was defined based on National Sleep Foundation recommendations. Logistic regression models assessed tobacco use status across seven categories (i.e., non-use [reference], current [past-month use] cigarette only, current e-cigarettes only, current dual use, former cigarette only, former e-cigarette only, and former dual use) with inadequate sleep, adjusting for demographics and health conditions. RESULTS: Overall, 40% of US adults with a history of CVD reported inadequate sleep. Current cigarette, e-cigarette, and dual use were associated with a relatively higher proportion of inadequate sleep duration. Unweighted findings revealed a significant association between current cigarette use (OR = 1.35, 95%CI: 1.26-1.44), e-cigarette use (1.40 [1.19-1.63]) and dual use (1.50 [1.27-1.77]) and increased odds of reporting inadequate sleep among adults with CVDs. Weighted analysis showed only a significant link between current cigarette use and inadequate sleep (1.34 [1.17-1.54]). CONCLUSIONS: Current cigarette use is associated with poor sleep in adults with CVDs. Unweighted findings suggested a similar association for e-cigarettes. Interventions targeting smoking cessation may offer promising avenues for improving sleep health and reducing the burden on adults with CVDs.
RESUMO
BACKGROUND: Current e-cigarette use has increased among young adults in the USA despite a consistent decrease in perceiving e-cigarettes as less harmful than cigarettes over time. This study examined time-varying predictors associated with the changes in e-cigarette relative harm perception over time among US young adults. METHODS: Data were from the 2013-2018 Population Assessment of Tobacco and Health (PATH) Study for young adults (18-24 years). A time-varying effect model (TVEM) was applied to examine the association between the relative harm perception change and the associated time-varying predictors. RESULTS: Of the 8427 young adults, the prevalence of those who perceived e-cigarettes as less harmful than cigarettes decreased from 50.3% in Wave 1 (2013-2014) to 27.7% in Wave 4 (2016-2018). Young adults who were male were more likely to perceive e-cigarettes as less harmful than cigarettes over time (OR = 1.58; 95%CI, 1.53-1.64). In addition, the changes in e-cigarette relative harm perception were less noticeable among those with advanced degrees, who had non-combustible smoke-free home rules, who held negative tobacco-related attitudes, and those who were current e-cigarette users or ever used alcohol (all p values < 0.05). CONCLUSIONS: A decline was observed in US young adults who perceived e-cigarettes as less harmful than cigarettes from the PATH Study across four waves (2013-2018). The study findings underscore the importance of risk communication that focuses on harm perception profiles and the need for appropriate interventions to balance the considerations of e-cigarette use among young adults.

OBJECTIVE: To evaluate the association between ideal cardiovascular health (CVH) and adipokine levels. Adipokines are hormones implicated in obesity and its cardiometabolic consequences. The concept of ideal CVH was introduced to promote 7 key health factors and behaviors in the general population. Previous studies have found strong associations between obesity and ideal CVH. However, existing literature on the link between CVH and adipokines is scarce. METHODS: We studied 1842 Multi-Ethnic Study of Atherosclerosis participants free of cardiovascular disease who had 7 CVH metrics (smoking, body mass index, physical activity, diet, total cholesterol, blood pressure, and fasting blood glucose) measured at baseline and serum adipokine levels measured at a median of 2.4 years later. Each CVH metric was assigned a score of 0 (poor), 1 (intermediate), or 2 (ideal), and all scores were summed for a total CVH score (0-14). The total CVH scores of 0 to 8, 9 to 10, and 11 to 14 were considered inadequate, average, and optimal, respectively. We used multivariable linear regression models to assess the nonconcurrent associations between the CVH score and log-transformed adipokine levels. RESULTS: The mean age was 62.1 ± 9.8 years; 50.2% of participants were men. After adjusting for sociodemographic factors, a 1-unit higher CVH score was significantly associated with 4% higher adiponectin and 15% and 1% lower leptin and resistin levels. Individuals with optimal CVH scores had 27% higher adiponectin and 56% lower leptin levels than those with inadequate CVH scores. Similar trends were observed for those with average versus inadequate CVH scores. CONCLUSION: In a multi-ethnic cohort free of cardiovascular disease at baseline, individuals with average and optimal CVH scores had a more favorable adipokine profile than those with inadequate CVH scores.

BACKGROUND: Pictorial health warning label (PHWL) is an effective risk communication measure among cigarette smokers. However, there is a lack of knowledge regarding the effect of PHWL on low- and high-frequency waterpipe (WP) smokers. This study examined the effects of PHWL on puffing behavior, subjective experiences, and toxicant exposures among low- and high-frequency WP smokers in the United States (US). METHODS: Sixty current (past-month) WP smokers (low-frequency; n = 30 and high-frequency; n = 30) completed two 45-min ad libitum WP smoking sessions in a cross-over design study (WP with no-PHWL vs. WP with PHWL). We compared the mean differences of puff topography, expired carbon monoxide (eCO), plasma nicotine concentration, and subjective experiences between the two smoking groups. RESULTS: Mean age of low-frequency smokers was 21.5 years and high-frequency smokers was 21.3 years. Compared to high-frequency, low-frequency smokers had significant reduction in average total smoking time [mean difference (SD) = -7.6 (10.2) min vs. -2.6 (6.7) min, p = 0.03] and number of puffs [mean difference (SD) = -33.37 (70.7) vs. -0.70 (29.2), p = 0.02] following exposure to PHWL compared to no-PHWL condition. Post-session subjective experiences were lower among high-frequency smokers compared to low-frequency smokers following smoking WP with PHWL compared to the no-PHWL session (puff liking -1.2 vs. -0.5; puff satisfaction -1.0 vs. -0.3; craving reduction -0.5 vs. 1.2) (p < 0.05 for all). CONCLUSION: Our findings indicate that placing PHWL on the WP device may be a promising strategy with differential effectiveness among WP smokers: low-frequency (reduce puffing behaviors) and high-frequency (reduce smoking experience).

Background: This study aimed to examine the trend and factors associated with smoking marijuana from a hookah device among US adults. Methods: Data were drawn from the Population Assessment of Tobacco and Health (PATH) Study, an ongoing nationally representative, longitudinal cohort study of the US population. Adult respondents who self-reported ever smoking marijuana from a hookah at Wave 5 (2018-19, N = 34,279 US adults) were included in the multivariable analysis. Trend analysis also was conducted using National Cancer Institute JoinPoint software from 2015 to 2019. Results: In 2018-19, an estimated 23.6 million (9.7%) US adults reported ever smoking marijuana from a hookah. Trend analysis showed the increasing prevalence of using marijuana from a hookah device from Wave 3 (8.9%) to Wave 5 (9.7%; time trend p = .007). Adults aged 25-44 years old (vs. 18-24; 13%, vs. 9%), whites (vs. Black; 11% vs. 9%), and lesbian, gay, or bisexual (LGB vs. straight; 17% vs. 9%) were more likely to report ever smoking marijuana from a hookah (ps < .05). Former and current users (vs. never users) of e-cigarettes (19% and 25% vs. 5%), cigarettes (11% and 21% vs. 2%), cigars (17% and 27% vs. 3%), and pipes (21% and 33% vs. 7%) and past 30-day blunt users (vs. non-users; 39% vs. 9%) were more likely to ever smoke marijuana from a hookah (ps < .05). Pregnant women (vs. non-pregnant; 12.8% vs. 8.6%; p = 0.03) were more likely to smoke marijuana from a hookah. Conclusions: Smoking marijuana from a hookah device is prevalent among young adults in the US, especially among vulnerable populations, and has increased significantly from 2015-2019.

Electronic nicotine delivery systems (ENDS) use has dramatically increased in the US. This study aimed to characterize changes in ENDS harm perception over time and associated predictors among US adolescents. Data from the 2013-2018 Population Assessment of Tobacco and Health Study (PATH) for adolescents (12-17 years) were utilized. Trend analyses were employed to delineate changes in comparative and absolute ENDS harm perception over a four-year interval. We applied a time-varying effect model (TVEM) to examine the associations between the changes in harm perception and associated predictors. The results suggest that perception of ENDS as less harmful than cigarettes significantly decreased from 54.3% at Wave 1 (2013) to 30.4% at Wave 4 (2018) (P < 0.001). Perception of ENDS as no or little harm decreased from 35.9% at Wave 1 to 16.9% at Wave 4 (P < 0.001). These changes in harm perception were less robust among males, adolescents who did not have positive tobacco-related attitudes, and those with smoke-free home rules (P's < 0.05). Additionally, having ever used ENDS or alcohol were more likely to be associated with reduced ENDS-related harm perception over time (P's < 0.05). Our results show that while ENDS-related harm perception have generally increased, this does not appear to be equally experienced across all adolescents, potentially highlighting the importance of at-risk groups and targets for intervention. This study can help identify individuals at risk of ENDS initiation because of their favorable ENDS harm perception profile, as well as guide the development of ENDS risk communication interventions for adolescents.

Depression is a mental health disorder associated with a 2-fold increase in cardiovascular disease risk. However, the association between depression and cardiovascular health (CVH), as reflected by the American Heart Association's (AHA) CVH metrics, is incompletely understood. We aimed to systematically review the current evidence to understand and clarify whether a bidirectional relationship exists between depressive symptoms and CVH. We conducted a systematic review by searching EMBASE, Google Scholar, PubMed and Web of Science from inception to May 2021. MeSH terms and keywords were used to identify studies with information on depressive symptoms and CVH. Among 132 articles screened, 11 studies were included with 101,825 participants. Eight studies were cross-sectional while 3 studies used a prospective cohort design. Five studies found an association between participants with unfavorable CVH and depressive symptoms. Six studies found an association between participants with depressive symptoms and unfavorable CVH. In summary, we found a bidirectional relationship may exist between depressive symptoms and CVH. Further research is required to quantify the risk and identify the biological mechanisms underlying the association between depressive symptoms and unfavorable CVH so adequate screening and interventions can be directed towards people with depressive symptoms or unfavorable CVH.

BACKGROUND: Exposure to famine during early life is related to several adverse health outcomes in adulthood, but the effect of famine exposure during adolescence is unclear. This study aims to examine whether exposure to famine in adolescence is associated with metabolic syndrome (MetS) in adulthood. METHODS: This study included 4130 Chinese adults (2059 males and 2071 females) aged 59-71 from the 2011 China Health and Retirement Longitudinal Study (CHARLS). All the selected participants were exposed to the three-year time period (1959-1961) of China's Great Famine. Participants were categorized into an adolescent-exposed group (born 01/01/1944-12/31/1948) and a non-adolescent-exposed group (born 01/01/1940-12/31/1941 and 01/01/1951-12/31/1952). Sex-stratified multiple logistic regression models were used to estimate the association between exposure to famine in adolescence and MetS. RESULTS: Participants exposed to famine during adolescence were more likely to report MetS (aOR = 1.35; 95%CI 1.01-1.78) compared to the non-adolescent-exposed group. Further, males were 45% less likely to report MetS than females (aOR = 0.55; 95%CI 0.36-0.83). After stratification by sex, the effects of famine exposure during adolescence on MetS were detected among males only (aOR = 1.97; 95%CI 1.20-3.24). Additionally, males with a history of drinking were more likely to report MetS compared to those with no history of drinking (aOR = 2.63; 95%CI 1.41-4.90). CONCLUSIONS: Our findings reveal that exposure to famine during adolescence is associated with higher odds of MetS in adulthood overall, and this association is only pronounced among males. This study emphasizes that undernutrition in early life, including adolescence, may have a long-term effect and be associated with adverse health events in middle-to-late life. Targeting those elderly people who suffered famine during adolescence may help prevent the development of MetS in later life.

This proof-of-concept study aims to evaluate the effect of placing graphic health warning labels (GHWLs) on the ENDS device on users' experience, puffing patterns, harm perception, nicotine exposure, and intention to quit or use in the future. JUUL users (n = 26, age 18-24 years; 69% male; 85% Hispanic) were recruited to complete two 60 minutes ad libitum sessions that differed by GHWL on the device (GHWL vs. no-GHWL control) in an experimental clinical lab study. Compared to the control session, using JUUL with GHWL on the device was significantly associated with reduced positive experiences such as pleasure, product liking, and user satisfaction (p-value < 0.05 for all). Also, after exposure to GHWL, participants were less interested in using the same product again (p-value = 0.007), even if it was the only product available on the market compared to control (p-value = 0.03). Trends toward reduced puffing behavior and nicotine boost were also noted during the GHWL, compared to control sessions. This pilot study shows that placing GHWL on the ENDS device may be an effective and promising strategy to reduce ENDS use among young people.

BACKGROUND: Waterpipe smoking (WPS) has been reported to have a wide range of damaging health effects on pulmonary and cardiovascular systems. Studies suggest that waterpipe tobacco smoking is associated with reduced harm perceptions, mental health problems and the use of psychoactive substances. We investigate the patterns of use and the association of WPS with anxiety, poly-tobacco and alcohol use in Lagos, Nigeria. MATERIALS AND METHODS: A cross-sectional study design was used to assess the data from 818 adolescents and adults in Lagos State, Nigeria. An online questionnaire obtained demographic information, waterpipe, e-cigarette, alcohol and other tobacco product use from respondents. Anxiety was assessed using the validated Generalised Anxiety Disorder 7-point scale. Bivariate and multivariate logistic regression analysis was used to identify the factors associated with waterpipe ever-use. P < 0.05 was considered statistically significant. RESULTS: The mean (standard deviation) age of respondents was 23.43 (±3.96), over half were female (55.2%) and a majority had a college diploma or more (88.59%). Among study participants, 18.58% reported waterpipe ever-use. Among ever waterpipe users, 17.33% reported current use (past 30-days), with a majority having smoked waterpipe in a bar or pub. Alcohol use (P < 0.001), e-cigarette ever-use (P: 0.010) and poly-tobacco ever-use (P: 0.030) were significantly associated with higher odds of waterpipe use in the multivariate regression model. Further, there was a lower likelihood of waterpipe ever-use in the bivariate regression model among respondents with mild and moderate to severe anxiety levels than those with normal anxiety levels (P: 0.030); however, this association was no longer significant in the adjusted model. CONCLUSIONS: Our findings suggest a relatively high prevalence of WPS in Lagos, Nigeria. Concurrent alcohol consumption, e-cigarette and poly-tobacco use are associated with WPS, and most waterpipe smokers have normal anxiety levels. The Nigerian Government should consider surveillance measures for WPS and a more comprehensive smoke-free policy.

Elevated resting heart rate (RHR) is associated with an increased cardiovascular disease (CVD) risk, but little is known about its association with cardiovascular health (CVH), assessed by the Life's Simple 7 (LS7) metrics. We explored whether ideal CVH was associated with RHR in a cohort free from clinical CVD. We conducted a cross-sectional analysis of baseline data (2000-2002) of 6457 Multi-Ethnic Study of Atherosclerosis participants in 2018. Each LS7 metric (smoking, physical activity, diet, body mass index, blood pressure, cholesterol and glucose) was scored 0-2. Total score ranged from 0 to 14. Scores of 0-8 indicate inadequate, 9-10 average, and 11-14 optimal CVH. RHR was categorized as <60, 60-69, 70-79 and ≥80â¯bpm. We used multinomial logistic regression to determine associations between CVH score and RHR, adjusting for age, sex, race/ethnicity, education, income, health insurance, and atrioventricular nodal blockers. Mean age of participants (standard deviation) was 62 (10) years; 53% were women; 47% had inadequate CVH, 33% average, and 20% optimal. Favorable CVH was associated with lower odds of having higher RHR. Compared to RHR <60â¯bpm, participants with optimal CVH had adjusted odds ratio (95% CI) of 0.55 (0.46-0.64) for RHR of 60-69â¯bpm, 0.34 (0.28-0.43) for 70-79â¯bpm, and 0.14 (0.09-0.22) for ≥80â¯bpm. A similar pattern was observed in the stratified analysis by sex, race/ethnicity and age. Favorable CVH was less likely to be associated with elevated RHR irrespective of sex, race/ethnicity and age. More research is needed to explore the usefulness of promoting ideal CVH to reduce elevated RHR, a known risk factor for CVD.

SIGNIFICANCE: Electronic nicotine delivery system (ENDS) use has continued to increase exponentially among young people in the USA, with unique flavours being one of the most cited reasons for use. Yet, controlled studies examining the effects of restricting flavour are lacking. This study evaluates the impact of ENDS flavour manipulation on user's puffing behaviour, subjective experience, harm perception and nicotine exposure among college-aged ENDS users. METHODS: JUUL users (n=30, age 18 to 24 years) attended two 60 min ad libitum ENDS use sessions (JUUL preferred flavour vs JUUL classic tobacco flavour) in a cross-over design. Puff topography and plasma nicotine concentration were measured, and participants completed subjective experience questionnaires. RESULTS: Increases were observed on measures of satisfaction, taste, enjoyment, urges to vape/smoke, pleasure, product appeal and increased concentration following using the preferred flavour pod (p values <0.05). Compared with preferred flavour, participants in the tobacco flavour were less motivated to use it in the future (70.9 vs 19.1 scores, p<0.001), even if it was the only product on the market (75.8 vs 30.7 scores, p<0.001). While nicotine levels significantly increased in both conditions from pre to post session (p values <0.001), no significant differences were observed in nicotine boost levels or on puff topography parameters when comparing both flavour conditions. CONCLUSIONS: This pilot study provides evidence that ENDS flavours have a substantial effect in enhancing young current ENDS users' experiences, product appeal and motivation to use the product in the future. It highlights that limiting flavours could play a potential role when designing strategic policies to reduce the appeal of ENDS use among young people.
RESUMO
BACKGROUND: Flavoured tobacco is one of the major factors behind the popularity of waterpipe (WP) smoking in the USA and internationally. The current study examined the impact of flavour manipulation on satisfaction, puff topography and toxicant exposure among high-frequency and low-frequency WP users. METHOD: This cross-over study was conducted among 144 current (past month) WP smokers reporting WP smoking less than once a week (low-frequency users; n=69) or at least once a week (high-frequency users; n=75) in the past 6 months. Participants attended two counterbalanced 45 min ad libitum smoking sessions that differed by flavour (preferred flavoured vs unflavoured tobacco), preceded by ≥12 hours of tobacco use abstinence. Outcome measures included puff topography, expired carbon monoxide (eCO), plasma nicotine and subjective measures. RESULTS: Both high-frequency and low-frequency WP users reported an enhanced smoking experience and greater interest in future use after smoking the flavoured compared with unflavoured tobacco (p<0.05 for all). High-frequency users, however, were more keen on smoking the flavoured tobacco in the future, had higher puffing parameters in general compared with low-frequency users (p<0.05 for all) and had no differences in eCO and plasma nicotine concentrations between the flavoured and unflavoured tobacco conditions (p>0.05 for all). On the other hand, low-frequency users had significantly greater eCO and plasma nicotine concentrations following smoking the unflavoured compared with flavoured tobacco condition (p<0.05 for all). CONCLUSIONS: Our results indicate that removing flavours will likely negatively affect WP satisfaction and future use and that such an effect will be more pronounced among high-frequency compared with low-frequency WP smokers.

INTRODUCTION: Limited research exists describing young people's knowledge and risk perception of e-cigarettes and hookah in Nigeria. This qualitative study explored the knowledge and risk perception of e-cigarettes and hookah amongst young people in Lagos, Nigeria. METHODS: Participants (n = 20), aged 15-24 years who had used e-cigarettes or hookah at least once in the past 12 months, participated in three focus group (FG) discussions in January 2020. Each FG session consisted of 6-7 participants, was facilitated by a trained moderator and lasted approximately 60 min. Sessions were recorded, and notes were taken after informed consent. Recordings were transcribed verbatim and analysed using NVIVO 10 software. RESULTS: An essential element of our findings was that the majority of the participants seemed to be more aware of hookah and used hookah compared to e-cigarettes. The participants mentioned they used these tobacco products mainly to reduce stress, for pleasure and for social acceptance. Most of the study participants reported that they were aware of some adverse health effects associated with e-cigarette or hookah use. Although some participants felt that the use of e-cigarettes or hookah could transform to cigarette smoking, many felt that e-cigarette was a harm reduction tool. CONCLUSION: Young users of e-cigarettes and hookah continue to use these products though they are aware of some associated adverse health effects. These products are used primarily for relieving stress and for social reasons. Raising awareness of the risks associated with the use of these tobacco products may help to reduce the acceptability of these products amongst youths.

BACKGROUND: Multiparity is associated with a greater risk of incident cardiovascular disease. However, the relationship of parity with cardiovascular health, as measured by the American Heart Association Life's Simple 7 metrics, is uncertain. OBJECTIVE: We aimed to examine the association between parity and ideal cardiovascular health among 3430 women, aged 45-84 years, free of clinical cardiovascular disease enrolled in the Multi-Ethnic Study of Atherosclerosis. STUDY DESIGN: The Multi-Ethnic Study of Atherosclerosis is a prospective cohort study that recruited middle-aged to older women and men from 6 centers in the United States between 2000 and 2002. The study population comprised 38% White, 28% Black, 23% Hispanic, and 11% Chinese American subjects. Parity (total number of live births) was self-reported and categorized as 0, 1-2, 3-4 and ≥5. The Life's Simple 7 metrics, defined according to American Heart Association criteria, include health behaviors (smoking, physical activity, body mass index, diet) and health factors (blood pressure, total cholesterol, and blood glucose). We categorized each metric into ideal (2 points), intermediate (1 point), and poor (0 points). A total cardiovascular health score of 0-8 was considered inadequate; 9-10, average; and 11-14, optimal. We used multinomial logistic regression to examine the cross-sectional association between parity and the cardiovascular health score, adjusted for sociodemographics, field site, hormone therapy, and menopause. RESULTS: The mean (standard deviation) age was 62 (10) years. The mean (standard deviation) cardiovascular health score was lower with higher parity (8.9 [2.3], 8.7 [2.3], 8.5 [2.2], and 7.8 [2.0] for 0, 1-2, 3-4, and ≥5 live births, respectively). In comparison to inadequate cardiovascular health scores, the adjusted odds of average cardiovascular health scores were significantly lower for all parity categories relative to nulliparity (prevalence odds ratios [OR] for parity of 1-2, 0.64 [95% confidence interval 0.49-0.83]; 3-4, 0.65 [0.49-0.86]; ≥5, 0.64 [0.45-0.91]). Women with ≥5 live births had a lower prevalence of optimal cardiovascular health scores (OR 0.50 [0.30-0.83]). In the fully adjusted models, the association between parity and each Life's Simple 7 metric was only statistically significant for body mass index. Women with ≥5 live births had lower prevalence of ideal body mass index (OR 0.52 [0.35-0.80]). In addition, the test for interaction showed that the association between parity and cardiovascular health was not modified by race/ethnicity (P = .81 for average cardiovascular health scores and P = .20 for optimal cardiovascular health scores). CONCLUSION: Multiparity was associated with poorer cardiovascular health, especially for women with ≥5 live births. More research is required to explore the mechanisms by which parity may worsen cardiovascular health.

The incidence of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfection has been increasing with over 10 million people affected globally. The role biomarkers play as predictors of cardiovascular disease (CVD) risk among coinfected individuals is not well defined. We aimed to systematically review current evidence describing CVD biomarkers among individuals with HIV/HCV coinfection. We searched EMBASE, CINAHL, Google Scholar, PubMed, and Web of Science from inception to June 2017. MeSH terms and keywords were used to identify studies with information on HIV/HCV coinfection and CVD biomarkers (structural, functional, and serological) such as carotid intima-media thickness (CIMT), endothelial markers, C-reactive protein (CRP), homocysteine, and lipids. Among 332 articles screened, 28 were included (39,498 participants). Study designs varied: 18 cross-sectional, 9 cohort, and 1 clinical trial. Compared with healthy controls and people with HIV or HCV monoinfection, individuals with HIV/HCV coinfection had statistically significant lower levels of lipids and CRP and higher levels of endothelial markers (sICAM-1 and sVCAM-1), CIMT, homocysteine, and IL-6. One study found the odds of carotid plaque in coinfected individuals was 1.64 (0.91-2.94) compared with healthy controls, and another study showed the prevalence of vascular plaques (carotid and femoral) in coinfected individuals was higher compared with HIV monoinfected individuals (44% vs 14%, P = 0.04). Biomarkers of CVD have different patterns of association with HIV/HCV coinfection compared with monoinfection and healthy controls. Prospective studies are needed to confirm the predictive value of these biomarkers for clinical CVD risk among coinfected individuals.

BACKGROUND: Given the unique social nature of waterpipe smoking, an important factor contributing to its popularity is the spread of waterpipe establishments. OBJECTIVES: With a focus on implications for regulations, we conducted a qualitative assessment of customers' online reviews on Yelp.com to gain insight into their positive and negative perceptions about waterpipe establishments and products, and identify features that are most important to them. METHODS: In June 2016, an online search of Yelp was conducted to identify waterpipe establishments in Miami, Florida. First, we collected information from the websites on establishments' characteristics and their marketing practices. Then we selected customers' waterpipe-related reviews and used an inductive qualitative method to code and identify key themes associated with positive and negative customers' experiences. Thematic analysis was completed upon reaching saturation. The final coding scheme consisted of 32 codes within eight themes. RESULTS: The homepage of the establishment was used to promote special discounts and events, while the online waterpipe menu was used to promote the waterpipe products. Our thematic analysis indicated that the variety of flavored tobacco was the most rated positive factor to customers, while the low-quality charcoal and high price were the most negative factors. Conclusions/Importance: Waterpipe online advertisements and promotions should be monitored and restricted. The availability of flavored tobacco, innovative device/accessories, affordable pricing, and charcoal quality are important domains for waterpipe establishments policy/regulation. Regulatory framework for waterpipe establishments should address the complex context of waterpipe including the venue (i.e., physical, website, menu), the tobacco, the device/accessories, and charcoal.

BACKGROUND OF THE STUDY: Low adherence is an essential element responsible for impaired effectiveness and efficiency in the pharmacological treatment of hypertension. Patient satisfaction is an important measure of healthcare quality and is a crucial determinant of patients' perspective on behavioural intention. AIMS: This study determined the association between medication adherence and treatment satisfaction among hypertensive patients attending hypertension outpatient clinic in Lagos University Teaching Hospital (LUTH), Nigeria. MATERIALS AND METHODS: Setting - The study setting was LUTH; a descriptive cross-sectional study was conducted. Study design - Hypertensive patients were consecutively recruited from the outpatient clinic. Medication adherence was assessed using the 8-item Morisky Medication Adherence Scale and treatment satisfaction was assessed using the 14-item Treatment Satisfaction Questionnaire for Medication. STATISTICAL ANALYSIS: Univariate and linear regression analyses were conducted using STATA software version 14.1 (StataCorp LP, College Station, TX, USA). Statistical significance was set at P ≤ 0.05. RESULTS: A total of 500 respondents with a mean age of 58.9 ± 13.3 years participated in the study. Overall, majority (446 [89.2%]) of the respondents in this study had 'moderate' adherence to antihypertensive medication. However, only five (1.0%) respondents reported 'high' adherence. Mean scores were highest in the moderate adherence category for all satisfaction domains and overall domain. Treatment satisfaction was associated with medication adherence, and was statistically significant (P = 0.000). CONCLUSION: One in every hundred patients had high adherence to hypertensive medication in this study, and there was a positive association between treatment satisfaction and medication adherence. Continuous patient-specific and tailored adherence education and counselling for hypertensive patients is recommended.
