Racial/Ethnic and Nativity Patterns of U.S. Adolescent and Young Adult Smoking

Predicting Young Adult Tobacco, Drug and Alcohol Use Among Participants in the CAMP Trial

The development of substance abuse in youth with asthma have seldom been examined with longitudinal research. The prospective and well-characterized CAMP cohort provides outcome data on youth with asthma over 13 years. This manuscript seeks to determine the contributions of asthma features and child behavioral/emotional functioning to subsequent tobacco, alcohol, and drug use in early adulthood. Childhood smoking exposures as well as parent report and youth report of substance use were prospectively assessed concurrently with assessments of asthma symptoms, study medication, and lung development. Logistic regression models evaluated predictors of adolescent and young adult tobacco, alcohol, and drug use. Use of tobacco products was reported by 33% of youth with mild/moderate asthma. Tobacco use was significantly associated with self-reported externalizing behaviors. Early life passive smoke exposure, especially in utero exposure, makes a significant contribution to tobacco use (OR1.58). Greater risk for tobacco use is conveyed by self-reported externalizing behaviors, which are consistently robust predictors of any future use of tobacco products, alcohol and drugs. These findings provide evidence for health care providers to use routine behavioral screening in youth with asthma.

The Role of Ethnicity and Nativity in the Correspondence between Subjective and Objective Measures of In-Home Smoking

Studies are needed to understand the association between self-reported home smoking bans and objective measures of in-home smoking according to smokers' ethnicity/nativity. Data came from a trial that used air particle monitors to reduce children's secondhand smoke exposure in smokers' households (N = 251). Linear regressions modeled (a) full home smoking bans by ethnicity/nativity, and (b) objectively measured in-home smoking events, predicted by main and interaction effects of self-reported home smoking bans and ethnicity/nativity. Among smokers reporting < a full ban, US-born and Foreign-born Latinos had fewer in-home smoking events than US-born Whites (p < 0.001). Participants who reported a full smoking ban had a similar frequency of smoking events regardless of ethnicity/nativity. Results indicate that self-reported home smoking bans can be used as a proxy for in-home smoking. Establishing smoking bans in the households of US-born White smokers has the largest impact on potential exposure compared to other ethnicity/nativity groups.

Spatial Disparities: The Role of Nativity in Neighborhood Exposure to Alcohol and Tobacco Retailers

Studies of retail environment, one of the social determinants of health, document racial/ethnic disparities in exposure to alcohol and tobacco (A and T) retailers, but have largely overlooked nativity. We examined associations between A and T retailer density and rates of foreign-born Latinx and foreign-born Asian residents in California census tracts (N = 7888), using spatial regressions and controlling for population and ecological confounders (e.g., population density, zoning, residential instability, urbanicity). Socio-demographic data came from the American Community Survey (2012-2016); census tract density of A and T retailers came from geocoded addresses from state license data for off-sale alcohol distributors and purchased data on tobacco retailers from a commercial provider. Models predicting A and T tract retailer density showed that the rate of foreign-born Latinx residents was associated with higher tobacco retailer density but lower alcohol retailer density, and demonstrate no significant associations between rate of foreign-born Asian residents tobacco and alcohol retail density. Retail environment could contribute to observed declines in immigrant health over time in the US and across generations.

Black Nativity and Health Disparities: A Research Paradigm for Understanding the Social Determinants of Health

After more than a century of research and debate, the scientific community has yet to reach agreement on the principal causes of racialized disparities in population health. This debate currently centers on the degree to which "race residuals" are a result of unobserved differences in the social context or unobserved differences in population characteristics. The comparative study of native and foreign-born Black populations represents a quasi-experimental design where race is "held constant". Such studies present a unique opportunity to improve our understanding of the social determinants of population health disparities. Since native and foreign-born Black populations occupy different sociocultural locations, and since populations with greater African ancestry have greater genetic diversity, comparative studies of these populations will advance our understanding of the complex relationship between sociocultural context, population characteristics and health outcomes. Therefore, we offer a conceptual framing for the comparative study of native and foreign-born Blacks along with a review of 208 studies that compare the mental and physical health of these populations. Although there is some complexity, especially with respect to mental health, the overall pattern is that foreign-born Blacks have better health outcomes than native-born Blacks. After reviewing these studies, we conclude with suggestions for future studies in this promising area of social and medical research.

Impact of preexisting type 2 diabetes mellitus and antidiabetic drugs on all-cause and cause-specific mortality among Medicaid-insured women diagnosed with breast cancer

BACKGROUND

We investigated the influence preexisting type 2 diabetes mellitus (T2DM) and antidiabetic drugs have on all-cause and cause-specific mortality among Medicaid-insured women diagnosed with breast cancer.

METHODS

9221 women aged <64 years diagnosed with breast cancer and reported to the New York State (NYS) Cancer Registry from 2004 to 2016 were linked with Medicaid claims. Preexisting T2DM was determined by three diagnosis claims for T2DM with at least one claim prior to breast cancer diagnosis and a prescription claim for an antidiabetic drug within three months following breast cancer diagnosis. Estimated menopausal status was determined by age (premenopausal age <50; postmenopausal age ≥50). Hazard ratios (HR) and 95 % confidence intervals (95 %CI) were calculated with Cox proportional hazards regression, adjusting for confounders.

RESULTS

Women with preexisting T2DM had greater all-cause (HR = 1.40; 95 %CI 1.21, 1.63), cancer-specific (HR = 1.24; 95 %CI 1.04, 1.47), and cardiovascular-specific (HR = 2.46; 95 %CI 1.54, 3.90) mortality hazard compared to nondiabetic women. In subgroup analyses, the association between T2DM and all-cause mortality was found among non-Hispanic White (HR 1.78 95 %CI 1.38, 2.30) and postmenopausal (HR = 1.47; 95 %CI 1.23, 1.77) women, but not among other race/ethnicity groups or premenopausal women. Additionally, compared to women prescribed metformin, all-cause mortality hazard was elevated among women prescribed sulfonylurea (HR = 1.44; 95 %CI 1.06, 1.94) or insulin (HR = 1.54; 95 %CI 1.12, 2.11).

CONCLUSION

Among Medicaid-insured women with breast cancer, those with preexisting T2DM have an increased mortality hazard, especially when prescribed sulfonylurea or insulin. Further research is warranted to determine the role antidiabetic drugs have on survival among women with breast cancer.

The association of nativity/length of residence and cardiovascular disease risk factors in the United States

Differences by nativity status for cardiovascular disease (CVD) risk factors have been previously reported. Recent research has focused on understanding how other acculturation factors, such as length of residence, affect health behaviors and outcomes. This study examines the association between CVD risk factors and nativity/length of US residence. Using cross-sectional data from 15,965 adults in the 2011-2016 National Health and Nutrition Examination Surveys (analyzed in 2018), prevalence ratios and predicted marginals from logistic regression models are used to estimate associations of CVD risk factors (i.e., hypertension, hypercholesterolemia, diabetes, overweight/obesity and smoking) with nativity/length of residence (<15 years, ≥15 years) in the US. In sex-, age-, education- and race and Hispanic origin- adjusted analyses, a higher percentage of US (50 states and District of Columbia) born adults (86.4%) had ≥1 CVD risk factor compared to non-US born residents in the US <15 years (80.1%) but not ≥15 years (85.1%). Compared to US born counterparts, regardless of length of residence, hypertension overall and smoking among non-Hispanic white and Hispanic adults were lower among non-US born residents. Overweight/obesity overall and diabetes among Hispanic adults were lower among non-US born residents in the US <15 years. In contrast, non-US born non-Hispanic Asian residents in the US <15 years had higher prevalence of diabetes. Non-US born adults were less likely to have most CVD risk factors compared to US born adults regardless of length of residence, although, for smoking and diabetes this pattern differed by race and Hispanic origin.

Living race together: the role of partner's race in racial/ethnic differences in smoking

Objective: Crossing racial lines provides a unique context for understanding racial patterns in smoking. This research explores whether adults whose unions cross racial lines behave more similarly to their own group or their partner'sDesign: Using a sample of respondents from the National Health Interview Survey (2001-2011), we compare the likelihood of current smoking and quitting smoking among adults in mixed-race unions to adults in same-race unions.Results: Adults with different-race partners generally mirror their partner's group; people of color with White partners have a higher likelihood of being current smokers, similar to Whites, while Whites partnered with Asians and Latina/os are, like other Asians and Latino/as, less likely to smoke. There are fewer differences in the likelihood of quitting smoking.

Racial/Ethnic Differences in Duration of Smoking Among Former Smokers in the National Health and Nutrition Examination Surveys

Introduction

The burden of tobacco-related disease is not uniformly distributed across racial/ethnic groups. Differences in smoking duration by race/ethnicity may contribute to this disparity. Previous studies have examined racial/ethnic differences in smoking duration among ever smokers (former and current smokers combined). It is unknown if racial/ethnic differences in smoking duration are evident among quitters. This study examined racial/ethnic differences in duration of smoking among former smokers in the United States.

Methods

We studied 6030 white, black, and Mexican-American former smokers (3647 men and 2383 women) aged 20-79 years who participated in the National Health and Nutrition Examination Survey (NHANES) from 1999 through 2012. Mean differences in smoking duration by race/ethnicity were estimated using linear regression models.

Results

After adjustment for demographics, age at smoking initiation and smoking intensity, compared to white men, black men smoked for 2.3 (95% confidence interval [CI]: 1.3, 3.3) years longer before quitting and Mexican-American men for 0.2 (95% CI: -1.6, 1.2) years less before quitting. Compared to white women, black women smoked for 1.9 (95% CI: 0.7, 3.0) years longer before quitting and Mexican-American women for 0.9 (95% CI: -2.4, 0.5) years less before quitting.

Conclusions

In a representative sample of US adults, black former smokers continued smoking for longer periods before quitting compared to white former smokers. These findings support the need for smoking cessation efforts that address racial/ethnic differences in smoking behaviors. The longer time to quit among black former smokers should be investigated as an explanation for racial/ethnic disparities in smoking-associated diseases.

Implications

In a representative sample of US adults that successfully quit smoking, the timing of smoking cessation differed by race/ethnicity with blacks smoking for longer periods before quitting compared to whites. Racial/ethnic differences in duration of smoking among former smokers differed by participant age and age at smoking initiation. These findings support the need for smoking cessation efforts that address racial/ethnic differences in smoking behaviors.

Disaggregating Asian American and Native Hawaiian and Other Pacific Islander (AANHOPI) Adult Tobacco Use: Findings from Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study, 2013-2014

INTRODUCTION

Tobacco studies often combine data for Asian American and Native Hawaiian and Other Pacific Islander (AANHOPI) subgroups, masking subgroup differences. This study describes tobacco use (ever use and past 30-day use) among some disaggregated AANHOPI subgroups.

METHODS

Data are from Wave 1 of the 2013-2014 Population Assessment of Tobacco and Health (PATH) Study, a nationally representative, longitudinal cohort study of civilian non-institutionalized adults and youth in the USA. The dataset contains a sample of 32,320 adults, of which 1623 identified as being of AANHOPI origin. Asian Americans further identified as being Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese, or other Asian. Those who identified as Native Hawaiian, Guamanian or Chamarro, Samoan, and Other Pacific Islander were combined into an NHOPI group. Tobacco measures included ever and past 30-day use of cigarettes, e-cigarettes, cigars (traditional cigar, cigarillos, filtered cigar), hookah, and smokeless tobacco including snus pouches, and pipe tobacco. Unadjusted and adjusted estimates for tobacco use are reported by AANHOPI membership and sex.

RESULTS

In general, Asian Indians and Chinese had the lowest and NHOPI had the highest tobacco use prevalence compared to other AANHOPI subgroups. Males generally had higher prevalence compared to females. Prevalence varied by AANHOPI membership and tobacco product. Adjusted prevalence estimates were higher compared to unadjusted estimates for many subgroups, attenuating some unadjusted differences found between AANHOPI subgroups.

DISCUSSION

Tobacco use varies by AANHOPI subgroup and product type. Unadjusted and adjusted analyses can be conducted as tobacco use differences in AANHOPI subgroups may be attributed to socio-economic status differences. Treating these distinct subgroups as a monolithic group may contribute to reliance on tobacco prevention and control strategies that may have limited impact on specific subgroups.

Nicotine and addiction beliefs and perceptions among the US-born and foreign-born populations

Little is known about nicotine and addiction beliefs held by those who are foreign-born in the US and how these beliefs are associated with acculturation and race/ethnicity. This study attempts to address these research gaps. Data were analyzed from two cycles of the Health Information National Trends Survey, HINTS-FDA 2015 (n = 3738) and HINTS-FDA 2017 (n = 1736). HINTS-FDA is a tobacco-focused, cross-sectional, nationally representative survey of US non-institutionalized civilian adults aged 18 years or older. We first assessed associations between foreign-born status and beliefs about nicotine and addiction using weighted chi-square analyses. Then, using only the foreign-born sample, we examined the associations of nicotine and addiction beliefs with race/ethnicity and acculturation (i.e., English proficiency and U.S. tenure) using weighted multiple linear regression. Results showed that, compared to US-born respondents, foreign-born respondents were more likely to be concerned with being addicted to nicotine and to believe that low nicotine cigarettes would have much lower lung cancer risk than a typical cigarette. Among the foreign-born, NH-Black and Hispanic respondents were more likely to see low nicotine cigarettes as harmful and addictive compared to NH-White respondents. The relationship between acculturation and nicotine beliefs was complex with lower acculturation associated with elevated misperceived risk of nicotine and also ratings of addictiveness. Further research among key subpopulations may inform communication, education and dissemination strategies, especially among vulnerable populations.

Ethnic Differences in Cigarette Use Trajectories and Health, Psychosocial, and Academic Outcomes

PURPOSE

Cigarette smoking among youth is associated with poorer health and psychosocial outcomes. However, few studies address how smoking may differentially relate to the emergence of disparities in functioning across races/ethnicities over adolescence.

METHODS

Youth (n = 2,509) were surveyed eight times from ages 11 to 18. We measured cigarette use, academic and social functioning, mental and physical health, and delinquency. Sequelae of change models controlled for sociodemographic factors, and tested whether intercept and slope for smoking trajectories were associated with outcomes at the end of high school, and examined racial/ethnic differences in outcomes assuming similar smoking trajectories across groups.

RESULTS

Youth were 45% Hispanic, 20% Asian, 20% white, 10% multiethnic, 2% black, and 1% other ethnicities. Higher average probability of smoking and steeper slopes of smoking trajectories were associated with poorer outcomes in multiple domains. Controlling for smoking trajectories, we observed the following disparities (vs. white youth; all p's < .05): black, Hispanic, and multiethnic youth reported lower academic performance; Asian, black, and multiethnic youth reported higher academic unpreparedness; Asian and multiethnic youth reported poorer mental health; Asian, Hispanic, and multiethnic youth reported poorer physical health; and Asian youth reported higher delinquency and poorer social functioning.

CONCLUSIONS

Statistically adjusting for similar smoking trajectories, racial/ethnic minority youth demonstrated poorer outcomes in multiple domains compared with white peers. Smoking may be a particularly robust marker for risk of negative outcomes in racial/ethnic minority youth. Screening for cigarette use and intervening on smoking and associated risk behaviors among minority youth may help reduce disparities in functioning.

Substance use, age at migration, and length of residence among adult immigrants in the United States

In this study we scrutinize prevalence of current smoking and binge drinking among adult US immigrants, and examine whether age at migration predicts these two behaviors and moderates the effect of length of residence. Immigrant groups include those from Latin America/Caribbean, East and South Asia, Sub-Saharan Africa, Europe/Central Asia, and Middle East/North Africa. Multivariate logistic regressions are estimated using cross-sectional data from the New Immigrant Survey (N = 7,397). Results show that patterns of smoking and binge drinking vary by gender and by region of origins. In addition, arriving at age 0-9 are directly associated with higher odds of binge drinking among adult women. Among adult men, age at migration moderates the association between length of residence and substance use. Specifically, length of residence has more detrimental effects for adolescent immigrants (arriving at age 10-18) on smoking, while its detrimental effects are more pronounced for childhood immigrants (arriving at age 0-9) on binge drinking. We interpret our findings within the critical period model in epidemiological research, concluding that adolescence and childhood are critical life stages that are associated with differential effects of length of residence when looking at smoking and binge drinking among immigrant men.

The relation between stress and alcohol use among Hispanic adolescents

We explored the relation between 8 domains of Hispanic stress and alcohol use and frequency of use in a sample of Hispanic adolescents between 11 and 19 years old (N = 901). Independent t tests were used to compare means of domains of Hispanic stress between adolescents who reported alcohol use and those who reported no use. In addition, multinomial logistic regression was used to examine whether domains of Hispanic stress were related to alcohol use and whether the relation differed by gender and age. Multiple imputation was used to address missing data. In the analytic sample, 75.8% (n = 683) reported no use and 24.2% (n = 218) reported alcohol use during the previous 30 days. Higher mean Hispanic stress scores were observed among youths who reported alcohol use during the previous 30 days in 5 domains: acculturation gap, community and gang violence, family economic, discrimination, and family and drug-related stress. Increased community and gang violence, family and drug, and acculturative gap stress were found to be associated with some alcohol use categories beyond the effect of other domains. Few differences in the association between Hispanic stress and alcohol use by gender and age were observed. Study findings indicate that family and drug-related, community and gang violence, and acculturative gap stress domains are salient factors related to alcohol use among Hispanic adolescents, and their implications for prevention science are discussed.

Light and intermittent smoking among California Black, Hispanic/Latino, and non-Hispanic White men and women

INTRODUCTION

The prevalence of light and intermittent smoking (LITS) is increasing as the prevalence of heavier smoking continues to fall. The purpose of this study was to examine changes in LITS over time among Blacks, Hispanic/Latinos (Latinos) and non-Hispanic Whites (Whites).

METHODS

Data from the California Tobacco Surveys from 1990, 1992, and 1996 (Time 1 [T1]) were combined and compared to combined data from 1999, 2002, 2005, and 2008 (Time 2 [T2]). T1 participants (N = 50,424) included Blacks (n = 3,029), Latinos (n = 7,910), and Whites (n = 39,485). T2 participants (N = 53,005) included Blacks (n = 5,460), Latinos (n = 14,273), and Whites (n = 33,246).

RESULTS

LITS increased by a factor of 12.9% to a rate of 79.6% (76.0-83.2) among Latinos, by 19.4% to a rate of 74.4% (70.9-77.9) among Blacks, and by 51.7% to a rate of 48.9% (47.5-50.3) among Whites. In unadjusted analyses at T1, females were more likely to be LITS than males across ethnic groups. At T2, this sex difference was maintained among Whites, but not Blacks and Latinos. Females were significantly more likely to be LITS than males when controlling for demographic variables.

CONCLUSIONS

The present study found that LITS rates increased over time for male and female Black, Latino and White adults. There is a need for increased tobacco control attention to LITS across all ethnic groups, but with additional focus on Blacks, Latinos, and women who have the highest rates of LITS.

Determinants of cigarette smoking initiation in Jordanian schoolchildren: longitudinal analysis

OBJECTIVE

To identify determinants of cigarette smoking initiation, by gender, among schoolchildren in Irbid, Jordan.

METHODS

Between 2008 and 2011, data were collected annually using self-reported questionnaires over 4-years in a prospective cohort of 1,781 students recruited from all 7th grade classes in 19 secondary schools, selected out of a total 60, using probability-proportionate-to-size method. Independent predictors of smoking initiation were identified among the cigarette naïve participants (N = 1,454) with mixed-effect multivariable logistic regression.

RESULTS

Participants were 12.6 years of age on average at baseline. 29.8% of the 1,454 students (37.2% of boys and 23.7% of girls) initiated cigarette smoking by 10th grade. Of those who initiated (n = 498), 47.2% of boys and 37.2% of girls initiated smoking in the 8th grade. Determinants of cigarette smoking initiation included ever smoking a waterpipe, low cigarette refusal self-efficacy, intention to start smoking cigarettes, and having friends who smoked. For girls, familial smoking was also predictive of cigarette initiation.

CONCLUSION

This study shows that many Jordanian youth have an intention to initiate cigarette smoking and are susceptible to cigarette smoking modeled by peers and that girls are influenced as well by familial cigarette smoking. Prevention efforts should be tailored to address culturally relevant gender norms, help strengthen adolescents' self-efficacy to refuse cigarettes, and foster strong non-smoking social norms.
