Assessing racial/ethnic and nativity disparities in US cancer mortality using a new integrated platform.

BACKGROUND: Foreign-born (FB) populations in the US have significantly increased, yet cancer trends remain unexplored. Survey-based Population-Adjusted Rate Calculator (SPARC) is a new tool for evaluating nativity differences in cancer mortality. METHODS: Using SPARC, we calculated 3-year (2016-2018) age-adjusted mortality rates (AAMRs) and rate ratios (RRs) for common cancers by sex, age group, race/ethnicity, and nativity. Trends by nativity were examined for the first time for 2006-2018. Traditional cancer statistics draw populations from decennial censuses. However, nativity-stratified populations are from the American Community Surveys, thus involve sampling errors. To rectify this, SPARC employed bias-corrected estimators. Death counts came from the National Vital Statistics System. RESULTS: AAMRs were higher among US-born (UB) populations across nearly all cancer types, with the largest UB- FB difference observed in lung cancer among Black females (RR = 3.67, 95%CI = 3.37-4.00). The well-documented White-Black differences in breast cancer mortality existed mainly among UB women. For all cancers combined, descending trends were more accelerated for the UB compared to the FB in all race/ethnicity groups with changes ranging from -2.6% per year in UB Black males to stable (non-significant) among FB Black females. Pancreas and liver cancers were exceptions with increasing, stable, or decreasing trends depending on nativity and race/ethnicity. Notably, FB Black males and FB Hispanic males did not show a favorable decline in colorectal cancer mortality. CONCLUSIONS: While all groups show beneficial cancer mortality trends, those with higher rates in 2006 have experienced sharper declines. Persistent disparities between the UB and the FB, especially among Black people, necessitate further investigation.

Trends and Patterns of Testosterone Therapy among U.S. Male Medicare Beneficiaries, 1999 to 2014.

PURPOSE: We explored the Medicare database (1999 to 2014) to provide a comprehensive assessment of testosterone therapy patterns in the older U.S. male population. MATERIALS AND METHODS: We estimated annual age-standardized incidence (new users) and prevalence (existing users) of testosterone therapy according to demographic characteristics, comorbidities and potential indications. RESULTS: There were 392,698 incident testosterone therapy users during 88 million person-years. Testosterone therapy users were predominantly younger, white nonHispanic, and located in South and West U.S. Census regions. On average testosterone therapy use increased dramatically during 2007 to 2014 (average annual percent change 15.5%), despite a decrease in 2014. In 2014 the most common recorded potential indications for any testosterone therapy were hypogonadism (48%), fatigue (18%), erectile dysfunction (15%), depression (4%) and psychosexual dysfunction (1%). Laboratory tests to measure circulating testosterone concentrations for testosterone therapy were infrequent with 35% having had at least 1 testosterone test in the 120 days preceding testosterone therapy, 4% the recommended 2 pre-testosterone therapy tests, and 16% at least 1 pre-testosterone therapy test and at least 1 post-testosterone therapy test. CONCLUSIONS: Testosterone therapy remains common in the older U.S. male population, despite a recent decrease. Although testosterone therapy prescriptions are predominantly for hypogonadism, a substantial proportion appear to be for less specific conditions. Testosterone tests among men prescribed testosterone therapy appear to be infrequent.

Assessing disparities in colorectal cancer mortality by socioeconomic status using new tools: health disparities calculator and socioeconomic quintiles.

PURPOSE: Colorectal cancer mortality rates dropped by half in the past three decades, but these gains were accompanied by striking differences in colorectal cancer mortality by socioeconomic status (SES). Our research objective is to examine disparities in colorectal cancer mortality by SES, using a scientifically rigorous and reproducible approach with publicly available online tools, HD*Calc and NCI SES Quintiles. METHODS: All reported colorectal cancer deaths in the United States from 1980 to 2010 were categorized into NCI SES quintiles and assessed at the county level. Joinpoint was used to test for significant changes in trends. Absolute and relative concentration indices (CI) were computed with HD*Calc to graph change in disparity over time. RESULTS: Disparities by SES significantly declined until 1993-1995, and then increased until 2010, due to a mortality drop in populations living in high SES areas that exceeded the mortality drop in lower SES areas. HD*Calc results were consistent for both absolute and relative concentration indices. Inequality aversion parameter weights of 2, 4, 6 and 8 were compared to explore how much colorectal cancer mortality was concentrated in the poorest quintile compared to the richest quintile. Weights larger than 4 did not increase the slope of the disparities trend. CONCLUSIONS: There is consistent evidence for a significant crossover in colorectal cancer disparity from 1980 to 2010. Trends in disparity can be accurately and readily summarized using the HD*Calc tool. The disparity trend, combined with published information on the timing of screening and treatment uptake, is concordant with the idea that introduction of medical screening and treatment leads to lower uptake in lower compared to higher SES populations and that differential uptake yields disparity in population mortality.

The role of worksite and home smoking bans in smoking cessation among U.S. employed adult female smokers.

PURPOSE: Examine the association of work and home smoking bans with quitting behaviors among employed female smokers in the United States. DESIGN: Secondary analyses using cross-sectional data from the 2006/2007 Tobacco Use Supplement to the Current Population Survey. SUBJECTS: Nationally representative sample of 7610 U.S. employed female smokers, aged 18 to 64 years, who reported working indoors. Setting . N/A. METHODS: Multivariate logistic regression analyses were conducted to examine the association of smoking ban policies (complete work and home bans, complete work ban only, complete home ban only, and no complete work or home ban) with intention to quit in the next 30 days, at least one quit attempt in the past year, and sustained abstinence of at least 3 months in the past year. RESULTS: Twenty-nine percent of women reported complete work and home smoking bans. Smoking bans were not associated with intention to quit and were marginally associated with sustained abstinence. Regardless of intention to quit, women with complete work and home bans were significantly more likely than those without complete work and home bans to report quit attempts. Among women with no intention to quit, the odds of having a quit attempt were significantly higher among women who had a complete home ban only compared with women without complete work and home bans. CONCLUSIONS: Efforts to promote quitting behaviors among employed female smokers may be facilitated by increasing rates of complete smoking bans at both work and home settings.

National patterns and correlates of mentholated cigarette use in the United States.

AIM: To examine the patterns and correlates of mentholated cigarette smoking among adult smokers in the United States. DESIGN: Cross-sectional data on adult current smokers (n = 63,193) were pooled from the 2003 and 2006/07 Tobacco Use Supplements to the Current Population Survey. MEASUREMENTS: The associations between socio-demographic and smoking variables were examined with gender- and race/ethnicity-stratified multivariate logistic regression models predicting current use of mentholated cigarettes. FINDINGS: Multivariate logistic regression analyses demonstrated that black smokers were 10-11 times more likely to smoke mentholated cigarettes than white smokers men: odds ratio (OR): 11.59, 99% confidence interval (CI): 9.79-13.72; women: OR: 10.12, 99% CI: 8.45-12.11). With the exception of American Indian/Aleut/Eskimo smokers, non-white smokers were significantly more likely to smoke mentholated cigarettes than were white smokers. Additional significant factors associated with mentholated cigarette smoking included being unmarried (never married: OR: 1.21, 99% CI: 1.09-1.34; divorced/separated: OR: 1.13, 99% CI: 1.03-1.23), being born in a US territory (OR: 2.01, 99% CI: 1.35-3.01), living in a non-metropolitan area (OR: 0.87, 99% CI: 0.80-0.96), being unemployed (OR: 1.24, 99% CI: 1.06-1.44) and lower levels of education. Race/ethnicity-stratified analyses showed that women were more likely than men to smoke mentholated cigarettes. Among black smokers, young adults (aged 18-24 years) were four times more likely to smoke mentholated cigarettes compared with individuals aged 65+. CONCLUSIONS: Race/ethnicity, gender and age are significant correlates of mentholated cigarette smoking among current smokers. Given the importance of menthol in the cigarette market and the potential untoward health effects of this additive, continued surveillance of the prevalence and correlates of mentholated cigarette use among diverse socio-demographic groups is warranted to inform appropriate interventions.

Nicotine dependence and quitting behaviors among menthol and non-menthol smokers with similar consumptive patterns.

AIMS: This study examines the associations between usual cigarette brand (i.e. menthol, non-menthol) and markers for nicotine dependence and quitting behaviors. DESIGN: The 2003 and 2006/07 Tobacco Use Supplements to the Current Population Surveys were pooled to conduct secondary data analysis. SETTING: National data were collected using in-person and telephone computer-assisted interviews by the United States Census Bureau among civilian, non-institutionalized people aged 15 years and older. PARTICIPANTS: Data were analyzed among daily current smokers aged 18+ (n = 46,273). MEASUREMENTS: The associations between usual cigarette brand and time to first cigarette within 5 and 30 minutes after waking, quit attempts in the past 12 months and length of smoking abstinence in the past 12 months were examined. Bivariate and multivariate logistic regression models were stratified by smoking intensity: ≤5, 6-10, 11-19 and 20+ cigarettes per day. FINDINGS: Menthol smokers reported a mean of 13.05 compared with 15.01 cigarettes per day among non-menthol smokers (P < 0.001). Multivariate results showed that among smokers consuming 6-10 cigarettes per day, menthol smokers were significantly more likely than non-menthol smokers to consume their first cigarette within 5 minutes after waking (odds ratio = 1.22, 95% confidence interval = 1.05,1.43). The multivariate models did not show significant associations between usual cigarette brand and quit attempts in past 12 months or duration of smoking abstinence >2 weeks in the past 12 months. CONCLUSIONS: Findings from this national survey of daily smokers demonstrate that menthol smokers in the United States who report consuming 6-10 cigarettes per day show greater signs of nicotine dependence than comparable non-menthol smokers.

Use of other tobacco products among U.S. adult cigarette smokers: prevalence, trends and correlates.

This paper examines the trends in concurrent use of cigarettes and other tobacco and sociodemographic variables associated with concurrent use among adult cigarette smokers in the United States. Data from the 1995/96, 1998, 2000, and 2001/02 Tobacco Use Supplements to the Current Population Survey were used to estimate concurrent use of tobacco among cigarette smokers among adults ages 18 years and older (n for all 4 survey groups=552,804). Concurrent use of tobacco fluctuated over the survey periods for current smokers and ranged from 3.7% in 1995/96 to 7.9% in 1998. Results from the multivariate logistic regression indicate that male current, daily, and intermittent smokers had substantially higher odds of concurrent use (OR=12.9, 11.7, 17.2, respectively) than their female counterparts. Age, race/ethnicity, geographic region, income, and survey years were significantly associated with concurrent use among current and daily smokers; for intermittent smokers, these variables and occupation were significantly associated with concurrent use. The strongest correlates for multiple tobacco use among cigarettes smokers were being male and Non-Hispanic White. These factors should be considered when planning tobacco prevention and control efforts. In addition, surveillance efforts should continue to monitor changes in concurrent use and further investigate the increased risk of cancer among smokers who also use other forms of tobacco.

Employment characteristics and socioeconomic factors associated with disparities in smoking abstinence and former smoking among U.S. workers.

PURPOSE: This study examines the associations among employment and socioeconomic factors and the outcomes, current smoking, cigarette abstinence and former smoking among adult U.S. workers ages 18-64 (n=288,813). METHODS: Multivariate logistic regression was used to examine the associations among the variables using cross-sectional data from the 1998-1999 and 2001-2002 Tobacco Use Supplements to the Current Population Survey. RESULTS: Lower odds of current smoking was observed among part-time workers compared to those working variable hours and multiple job holders compared to persons holding one job. The self-employed, part-time workers and multiple job holders had higher odds of former smoking than comparison groups. Employment factors were not associated with short-term abstinence or 12-month abstinence from smoking, but income, education, marital status, and duration of smoking were associated with 12-month abstinence. CONCLUSIONS: These data suggest that while employment factors are associated with current and former smoking, socioeconomic factors are associated with long-term quitting.

Cigarette smoking and quitting behaviors among unemployed adults in the United States.

Little is known about factors associated with smoking among the unemployed. This study estimated the prevalence of smoking and examined sociodemographic factors associated with current, former, and successful quitting among unemployed adults aged 18-64. Cross-sectional data on 13,480 participants in the 1998-1999 and 2001-2002 Tobacco Use Supplements to the Current Population Surveys were analyzed. Multivariate logistic regression analyses were used to examine factors associated with study outcomes (current vs. never, former vs. current, successful quitter vs. other former smoker). Among the unemployed, 35% were current smokers and 13% were former smokers. Of the former smokers, 81% quit successfully for at least 12 months. Participants with family incomes of less than US$25,000 were more likely than those with incomes of $50,000 or more to currently smoke (OR=2.13, 95% CI=1.85-2.46). Service workers and blue-collar workers were less likely than white-collar workers to report former smoking. Participants unemployed for 6 months or more were twice as likely as those unemployed for less than 6 months to quit successfully (OR=2.05, 95% CI=1.07-3.95). Unemployed blue-collar workers had a greater odds ratio of successfully quitting than white-collar workers (OR=1.83, 95% CI=1.17-2.87). Smoking rates were high among the unemployed, and quitting behaviors varied by sociodemographic factors and length of unemployment. Studies are needed to examine the feasibility of cessation interventions for the unemployed.
