ABSTRACT: Objectives
We investigated whether the effect of smoking on the incidence of smoking-related cancers differs by HIV-infection status, if sex modifies the impact of risk factors for smoking-related cancers, and the sex-specific attributable risk of smoking on cancer incidence.Design
Data from two large prospective studies in the United States were analyzed: 6789 men in the Multicenter AIDS Cohort Study from 1984 through 2018 and 4423 women in the Women's Interagency HIV Study from 1994 through 2018.Methods
Incidence rates, relative risks, and adjusted population attributable fractions (PAFs) were calculated for smoking-related cancers.Results
During study follow-up, there were 214 incident smoking-related cancers in the men and 192 in the women. The age-adjusted incidence ratess for smoking-related cancers were higher in the women (392/100 000) than for the men (198/100 000; P < 0.01) and higher for people living with HIV (PLWH, 348/100 000) than for those without HIV (162/100 000; P < 0.01). Unadjusted incidence rates in PLWH were higher than in those without HIV when stratifying by cumulative pack-years of smoking (all P values <0.01). In adjusted interaction models, the effects of cumulative pack-years of smoking were significantly stronger in women. The adjusted PAFs for smoking-related cancers were nonsignificantly higher in the women than in the men (39 vs. 28%; P = 0.35).Conclusion
HIV looks to be an independent risk factor for smoking-related cancers and women appear to have a greater risk than men. These results highlight the need for interventions to help PLWH, especially women, quit smoking and sustain cessation to reduce their risk of smoking-related cancers.

Project description:Perceived risk of smoking is associated with smoking status, interest in quitting, cessation attempts, and quit success. Research is needed to explore risk perceptions of developing smoking-related disease among persons living with HIV (PLWH). Data came from 267 HIV-positive smokers who completed an online survey assessing perceived health risks associated with (a) generic smoking status; (b) generic non-smoking status; (c) their own personal current smoking; and (d) a hypothetical situation in which they were a non-smoker. PLWH perceived greater risk associated with their current smoking versus hypothetical personal non-smoking (p's < 0.001), and greater risks associated with generic smoking status compared with their current smoking (p's < 0.001). Being on HIV medication (β = 0.65, 95% CI = 0.17, 1.12), interest in quitting smoking (β = 0.89, 95% CI = 0.45, 1.32), and having an HIV healthcare provider who has recommended cessation (β = 1.04, 95% CI = 0.42, 1.67) were positively associated with perceived risk of developing smoking-related diseases. Findings have implications for developing targeted interventions to correct misperceptions regarding the health risks of smoking among PLWH, a population at particular risk for smoking and smoking-related morbidity and mortality.

Project description:The authors prospectively examined whether caffeine intake was associated with lower risk of Parkinson disease (PD) in both men and women among 304,980 participants in the National Institutes of Health-AARP Diet and Health Study and whether smoking affected this relation. Multivariate odds ratios and 95% confidence intervals were derived from logistic regression models. Higher caffeine intake as assessed in 1995-1996 was monotonically associated with lower PD risk (diagnosed in 2000-2006) in both men and women. After adjustment for age, race, and physical activity, the odds ratio comparing the highest quintile of caffeine intake with the lowest was 0.75 (95% confidence interval: 0.60, 0.94; P(trend) = 0.005) for men and 0.60 (95% confidence interval: 0.39, 0.91; P(trend) = 0.005) for women. Further adjustment for duration of smoking and analyses carried out among never smokers showed similar results. A joint analysis with smoking suggested that smoking and caffeine may act independently in relation to PD risk. Finally, the authors conducted a meta-analysis of prospective studies and confirmed that caffeine intake was inversely associated with PD risk in both men and women. These findings suggest no gender difference in the relation between caffeine and PD.

Project description:INTRODUCTION:Despite extensive efforts to develop effective smoking cessation interventions, 70-85% of American cigarette smokers who quit relapse within one year. Exercise has shown promise as an intervention; however, many results have been equivocal. This study explored how exercise is associated with smoking-related symptomatology, smoking behavior and impulsivity in male and female smokers. METHODS:Participants were recruited throughout the United States using the on-line crowdsourcing platform, Amazon's Mechanical Turk. They completed a survey with self-report measures assessing exercise, smoking-related symptomatology, smoking behavior and impulsivity. Differences between men and women were tested using t- and chi-square tests. Regression analyses tested for associations between exercise and smoking-related symptomatology, smoking behavior and impulsivity. RESULTS:Participants (N?=?604) were, on average, 32 (SD?=?6.2) years old, mostly Caucasian, with at least some college education and approximately half were women. Women exercised slightly less than men and had more negative affect, craving, physical symptoms and withdrawal. Women smoked more cigarettes per day, had greater nicotine dependency and more years of smoking. Positive affect was positively associated with exercise for both men and women; however, this association was significantly stronger in women. Negative affect and withdrawal were inversely associated with exercise for women only. Impulsivity was inversely associated with exercise for both men and women. CONCLUSION:Exercise was significantly associated with several smoking-related symptomatology, smoking behavior and impulsivity variables for both men and women, suggesting that exercise may be a useful intervention for smoking cessation. Future prospective research should determine how exercise directly impacts smoking cessation.

Project description:Purpose of reviewTo synthesize current evidence on the impact of cardiovascular disease among women living with HIV (WLWH) with a particular focus on disease prevalence, mechanisms and prevention.Recent findingsHIV-related cardiovascular disease risk is 1.5-fold to 2-fold higher for women than for men. Mechanisms of enhanced risk are multifactorial and include reinforcing pathways between traditional risk factors, metabolic dysregulation, early reproductive aging and chronic immune activation. These pathways influence both the presentation of overt syndromes of myocardial infarction, stroke and heart failure, as well as subclinical disease, such as microvascular dysfunction and cardiac fibrosis. Cardiovascular disease, therefore, remains a consistent threat to healthy aging among WLWH.SummaryAlthough no specific prevention strategies exist, patient-centered risk mitigation approaches that are adaptable to the needs of aging individuals are essential to combat disparities in cardiovascular outcomes among WLWH. Further research into the optimal prevention approach for CVD among WLWH, particularly for women living in under-resourced health systems, is needed.

Project description:Psychological reactance is defined as the drive to re-establish autonomy after it has been threatened or constrained. People living with HIV may have high levels of psychological reactance due to the restrictions that they may perceive as a result of living with HIV. People living with HIV may also exhibit levels of HIV-related stigma. The relationship between psychological reactance and HIV-related stigma is complex yet understudied. Therefore, the main aim of this study was to examine the association between psychological reactance and HIV-related stigma among women living with HIV. Data were obtained from one time-point (a cross-sectional assessment) of a longitudinal HIV disclosure study. Psychological reactance was measured using the 18-item Questionnaire for the Measurement of Psychological Reactance. HIV-related stigma was measured using the HIV Stigma Scale, which has four domains: personalized, disclosure concerns, negative self-image, and concerns with public attitudes. Principal component analysis was used to derive components of psychological reactance. Linear regression models were used to determine the association between overall psychological reactance and its components, and stigma and its four domains, and depressive and anxiety symptoms. The associations between stigma and mental health were also examined. Three components of psychological reactance were derived: Opposition, Irritability, and Independence. Overall psychological reactance and irritability were associated with all forms of stigma. Opposition was linked to overall and negative self-image stigma. Overall psychological reactance, opposition, and irritability were positively associated with anxiety symptoms while opposition was also associated with Centers for Epidemiologic Studies-Depression depressive symptoms. There were also positive associations between all forms of stigma, and depressive and anxiety symptoms. Health-care providers and counselors for women living with HIV addressing feelings of irritability and opposition toward others may reduce HIV-related stigma. Future research should examine the link between psychological reactance, mental health, and HIV-related stigma among other populations living with HIV.

Project description:BackgroundHistorically, US women started smoking at a later age than men and had lower relative risks for smoking-related cancers. However, more recent birth cohorts of women and men have similar smoking histories and have now reached the high-risk age for cancer. The impact of these changes on cancer incidence has not been systematically examined.MethodsRelative risks (RR), 95% confidence intervals (CI) and attributable fractions were calculated for cigarette smoking and incidence of 20 smoking-related cancers in 186 057 women and 266 074 men of the National Institutes of Health-AARP cohort, aged 50 to 71 years in 1995 and followed for 11 years.ResultsIn the cohort, which included participants born between 1924 and 1945, most women and men started smoking as teenagers. RRs for current vs never smoking were similar in women and men for the following cancers: lung squamous-cell (RR women: 121.4, 95% CI: 57.3-257.4; RR men:114.6, 95% CI: 61.2-214.4), lung adenocarcinoma (RR women: 11.7, 95% CI: 9.8-14.0; RR men: 15.6, 95% CI: 12.5-19.6), laryngeal (RR women: 37.0, 95% CI: 14.9-92.3; RR men: 13.8, 95% CI: 9.3-20.2), oral cavity-pharyngeal (RR women:4.4, 95% CI: 3.3-6.0; RR men: 3.8, 95% CI: 3.0-4.7), oesophageal squamous cell (RR women: 7.3, 95% CI: 3.5-15.5; RR men: 6.2, 95% CI: 2.8-13.7), bladder (RR women: 4.7, 95% CI: 3.7-5.8; RR men: 4.0, 95% CI: 3.5-4.5), colon (RR women: 1.3, 95% CI: 1.2-1.5; RR men: 1.3, 95% CI: 1.1-1.4), and at other sites, with similar attributable fractions.ConclusionsRRs for current smoking and incidence of many smoking-related cancers are now similar in US women and men, likely reflecting converging smoking patterns.

Project description:BackgroundMen who have sex with men (MSM) and transgender women (TGW) are at risk for sexually transmitted infections (STIs), including those of the oropharynx. We estimated the prevalence and factors associated with oral sex practices and characterized oropharyngeal STIs among a cohort of MSM and TGW in Nigeria.MethodsFrom 2013 to 2018, TRUST/RV368 recruited MSM and TGW into HIV/STI diagnosis and treatment at community-based clinics in Nigeria. Participants who completed HIV testing and oral sex questions at enrollment were selected. Cross-sectional analyses with bivariate and multivariable logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs). Oropharyngeal swab testing for Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) began in 2014 and for those with diagnostic results at enrollment, the unadjusted association of oral sex practices with oropharyngeal STIs was conducted.ResultsA total of 1342 participants had a median age of 25 years (interquartile range: 22-29), 58% were living with HIV, and 69% reported oral sex practices. Factors associated with increased odds of engaging in oral sex included living with HIV (adjusted [a]OR: 1.4, 95% CI: 1.1-1.8), self-identifying as a woman (aOR:1.8, 95% CI: 1.1-2.8), mobile phone ownership (aOR:2.3, 95% CI: 1.3-3.9), receptive anal sex (aOR:1.7, 95% CI:1.3-2.3) and multiple male sexual partners (2 to 4 vs. ≤1, aOR:1.5, 95% CI: 1.0-2.2; 5+ vs ≤1, aOR:2.9, 95% CI:1.9-4.3). Oropharyngeal STI prevalence was 7% (52/752) and higher among those who engaged in oral sex compared to those who did not (unadjusted OR: 2.5, 95% CI:1.2-5.3).ConclusionsOral sex was common and associated with an increased odds of oropharyngeal STIs among MSM and TGW from Nigeria. In the absence of screening and treatment guidelines, condoms continue to be the mainstay for oral STI prevention. A pre-exposure prophylaxis for bacterial STIs would complement current prevention strategies to curb transmission.

Project description:Importance:The population of cancer survivors is rapidly growing in the US. Tobacco smoking is associated with many cancers; however, whether cigarette smoking behaviors among cancer survivors vary according to cancer type-that is, smoking-related cancers (SRCs) vs non-smoking-related cancers (NSRCs)-remains unclear. Objectives:To examine cigarette smoking prevalence and behaviors (ie, continuing or quitting smoking) among cancer survivors and to compare them between survivors of SRCs and NSRCs. Design, Setting, and Participants:This study was a cross-sectional analysis of the 2017 National Health Interview Survey, a household survey of civilian US residents who were aged 18 years or older. The National Health Interview Survey is population based and is representative of the US population. Data analysis was performed from June to October 2019. Main Outcomes and Measures:The primary outcomes were prevalence of current cigarette smoking among cancer survivors and prevalence of continuing smoking and quitting smoking after a cancer diagnosis. Secondary outcomes included factors associated with continued smoking vs quitting smoking after a cancer diagnosis. Results:A total of 26?742 respondents (mean [SD] age, 50.97 [18.61] years; 14?646 women [51.76%]) to the 2017 National Health Interview Survey were included in this study. Of the 3068 individuals (9.42%) in the study population who had cancer, 589 (19.96%) were SRC survivors, 2297 (74.50%) were NSRC survivors, 168 (4.96%) were survivors of both SRC and NSRC, and the remaining 14 (0.58%) had missing information about the type of cancer. Four hundred forty-nine SRC survivors (54.08%) were women, compared with 1412 NSRC survivors (54.30%). Ninety-six SRC survivors (15.69%) and 151 NSRC survivors (7.99%) were younger than 45 years. Overall, 372 cancer survivors (13.16%) were current smokers. Current smoking prevalence was higher among survivors of SRCs (145 survivors [19.78%]) compared with NSRC survivors (251 survivors [10.63%]). Among cancer survivors, 309 current smokers at cancer diagnosis (43.96%) reported having successfully quit smoking and 372 (56.04%) reported continuing smoking. Among the continuing smokers, 176 (56.49%) reported an unsuccessful quit attempt in the last 12 months. After cancer diagnosis, SRC survivors had higher odds of continued smoking compared with NSRC survivors (odds ratio [OR], 2.10; 95% CI, 1.12-3.93; P?=?.02). Men (OR, 1.93; 95% CI, 1.05-3.57; P?=?.04), those with angina pectoris (OR, 5.40; 95% CI, 1.33-21.91; P?=?.02), and those with chronic bronchitis (OR, 2.55; 95% CI, 1.05-6.19; P?=?.04) had higher odds of continued smoking, whereas Hispanic participants (compared with non-Hispanic white participants: OR, 0.18; 95% CI, 0.05-0.68; P?=?.01) and married participants (compared with never married participants: OR, 0.33; 95% CI, 0.12-0.96; P?=?.04) had lower odds of continued smoking. Conclusions and Relevance:These findings suggest that compared with NSRC survivors, SRC survivors may be at higher risk of being cigarette smokers at cancer diagnosis and of continuing smoking afterward. Although smoking cessation interventions are critically important for all cancer survivors, special efforts should target survivors of SRCs.

Project description:ObjectiveTo use accelerometers to quantify differences in physical activity (PA) by HIV serostatus and HIV viral load (VL) in the Multicenter AIDS Cohort Study (MACS).MethodsMACS participants living with (PLWH, n = 631) and without (PWOH, n = 578) HIV wore an ambulatory electrocardiogram monitor containing an accelerometer for 1-14 days. PA was summarized as cumulative mean absolute deviation (MAD) during the 10 most active consecutive hours (M10), cumulative MAD during the six least active consecutive hours (L6), and daily time recumbent (DTR). PA summaries were compared by HIV serostatus and by detectability of VL (>20 vs. ≤20 copies/ml) using linear mixed models adjusted for sociodemographics, weight, height, substance use, physical function, and clinical factors.ResultsIn sociodemographic-adjusted models, PLWH with a detectable VL had higher L6 (β = 0.58 mg, P = 0.027) and spent more time recumbent (β = 53 min/day, P = 0.003) than PWOH. PLWH had lower M10 than PWOH (undetectable VL β = -1.62 mg, P = 0.027; detectable VL β = -1.93 mg, P = 0.12). A joint test indicated differences in average PA measurements by HIV serostatus and VL (P = 0.001). However, differences by HIV serostatus in M10 and DTR were attenuated and no longer significant after adjustment for renal function, serum lipids, and depressive symptoms.ConclusionsPhysical activity measures differed significantly by HIV serostatus and VL. Higher L6 among PLWH with detectable VL may indicate reduced amount or quality of sleep compared to PLWH without detectable VL and PWOH. Lower M10 among PLWH indicates lower amounts of physical activity compared to PWOH.

Project description:CONTEXT:Previous studies indicate that the population attributable risk (PAR) of bladder cancer for tobacco smoking is 50% to 65% in men and 20% to 30% in women and that current cigarette smoking triples bladder cancer risk relative to never smoking. During the last 30 years, incidence rates have remained stable in the United States in men (123.8 per 100,000 person-years to 142.2 per 100,000 person-years) and women (32.5 per 100,000 person-years to 33.2 per 100,000 person-years); however, changing smoking prevalence and cigarette composition warrant revisiting risk estimates for smoking and bladder cancer. OBJECTIVE:To evaluate the association between tobacco smoking and bladder cancer. DESIGN, SETTING, AND PARTICIPANTS:Men (n = 281,394) and women (n = 186,134) of the National Institutes of Health-AARP (NIH-AARP) Diet and Health Study cohort completed a lifestyle questionnaire and were followed up between October 25, 1995, and December 31, 2006. Previous prospective cohort studies of smoking and incident bladder cancer were identified by systematic review and relative risks were estimated from fixed-effects models with heterogeneity assessed by the I(2) statistic. MAIN OUTCOME MEASURES:Hazard ratios (HRs), PARs, and number needed to harm (NNH). RESULTS:During 4,518,941 person-years of follow-up, incident bladder cancer occurred in 3896 men (144.0 per 100,000 person-years) and 627 women (34.5 per 100,000 person-years). Former smokers (119.8 per 100,000 person-years; HR, 2.22; 95% confidence interval [CI], 2.03-2.44; NNH, 1250) and current smokers (177.3 per 100,000 person-years; HR, 4.06; 95% CI, 3.66-4.50; NNH, 727) had higher risks of bladder cancer than never smokers (39.8 per 100,000 person-years). In contrast, the summary risk estimate for current smoking in 7 previous studies (initiated between 1963 and 1987) was 2.94 (95% CI, 2.45-3.54; I(2) = 0.0%). The PAR for ever smoking in our study was 0.50 (95% CI, 0.45-0.54) in men and 0.52 (95% CI, 0.45-0.59) in women. CONCLUSION:Compared with a pooled estimate of US data from cohorts initiated between 1963 and 1987, relative risks for smoking in the more recent NIH-AARP Diet and Health Study cohort were higher, with PARs for women comparable with those for men.
