Cultural Body Shape Ideals and Eating Disorder Symptoms Among White, Latina, and Black College Women

Previous studies have reported inconsistent relationships between body image, eating disorder symptoms, and acculturation-relevant variables. The current study examined these variables in a sample of White, Latina, and Black college women (N = 276). White and Latina participants selected slimmer personal body shape ideals than Black women. Among Black women, the discrepancy between perceived body shape and perceived ideal body shape for the United States was predictive of Eating Disorder Inventory Body Dissatisfaction (EDI-BD) and Drive for Thinness (EDI-DFT) scores. The discrepancy between perceived body shape and perceived ideal for their ethnic group also predicted EDI-BD scores. Among Latinas, the discrepancy between perceived body shape and perceived body shape ideal for their ethnic group was predictive of EDI-BD and EDI-DFT scores, whereas a discrepancy between perceived body shape and perceived ideal for the United States was not predictive of eating disorder symptoms. Finally, higher levels of acculturative stress, but not acculturation, were associated with EDI-BD scores among Black women and EDI-DFT scores among Latinas. Findings underscore the importance of considering cultural variables such as acculturative stress when conducting clinical work with ethnic minority women.

Financial Strain and Smoking Cessation Among Racially/Ethnically Diverse Smokers

OBJECTIVES We evaluated the influence of financial strain on smoking cessation among Latino, African American, and Caucasian smokers of predominantly low socioeconomic status. METHODS Smokers enrolled in a smoking cessation study (N = 424) were followed from 1 week prequit through 26 weeks postquit. We conducted a logistic regression analysis to evaluate the association between baseline financial strain and smoking abstinence at 26 weeks postquit after control for age, gender, race/ethnicity, educational level, annual household income, marital status, number of cigarettes smoked per day, and time to first cigarette of the day. RESULTS Greater financial strain at baseline was significantly associated with reduced odds of abstinence at 26 weeks postquit among those who completed the study (odds ratio [OR] = 0.77; 95% confidence interval [CI] = 0.62, 0.94; P = .01). There was a significant association as well in analyses that included those who completed the study in addition to those lost to follow-up who were categorized as smokers (OR = 0.78; 95% CI = 0.64, 0.96; P = .02). CONCLUSIONS Greater financial strain predicted lower cessation rates among racially/ethnically diverse smokers. Our findings highlight the impact of economic concerns on smoking cessation and the need to address financial strain in smoking cessation interventions.

Acculturation differentially predicts smoking cessation among Latino men and women.

Objectives: The current study examined the influence of gender, acculturation indicators, and their interaction on smoking cessation among Latinos. Methods: Logistic regression analysis was used to examine the main effects of gender, acculturation indicators, and their interactions on self-reported 7-day abstinence at 12-week follow-up among 271 Latino smokers seeking cessation counseling. Results: Analyses revealed significant main effects for several acculturation indicators and significant interactions of gender with number of years lived in the United States, proportion of life lived in the United States, and preferred media language (all P values <0.05). Follow-up analyses indicated no significant relationships between abstinence and acculturation indicators among women. Among men, abstinence rates increased with years in the United States, proportion of life in the United States, and preferred media language of English. Conclusions: Greater acculturation predicted higher abstinence rates, but this relationship was restricted to men. This study is among the first to examine the effects of gender and acculturation on smoking abstinence among Latinos. Findings highlight the need for research focused on mechanisms underlying these relationships. (Cancer Epidemiol Biomarkers Prev 2009;18(12):3468–75)

Alcohol use severity and depressive symptoms among late adolescent Hispanics: testing associations of acculturation and enculturation in a bicultural transaction model

Research has indicated that Hispanics have high rates of heavy drinking and depressive symptoms during late adolescence. The purpose of this study was to test a bicultural transaction model composed of two enthnocultural orientations (acculturation and enculturation); and stressful cultural transactions with both the U.S. culture (perceived ethnic discrimination) and Hispanic culture (perceived intragroup marginalization) to predict alcohol use severity and depressive symptoms among a sample of 129 (men=39, women=90) late adolescent Hispanics (ages 18-21) enrolled in college. Results from a path analysis indicated that the model accounted for 18.2% of the variance in alcohol use severity and 24.3% of the variance in depressive symptoms. None of the acculturation or enculturation domains had statistically significant direct effects with alcohol use severity or depressive symptoms. However, higher reports of ethnic discrimination were associated with higher reports of alcohol use severity and depressive symptoms. Similarly, higher reports of intragroup marginalization were associated with higher depressive symptoms. Further, both ethnic discrimination and intragroup marginalization functioned as mediators of multiple domains of acculturation and enculturation. These findings highlight the need to consider the indirect effects of enthnocultural orientations in relation to health-related outcomes.

Pathways Linking Socioeconomic Status and Postpartum Smoking Relapse

BackgroundLow socioeconomic status (SES) exacerbates the high rate of smoking relapse in women following childbirth.PurposeThis study examined multiple models of potential mechanisms linking SES and postpartum smoking relapse among women who quit smoking due to pregnancy.MethodsParticipants were 251 women enrolled in a randomized clinical trial of a new postpartum smoking relapse prevention intervention. Four models of the prepartum mechanisms linking SES and postpartum smoking relapse were evaluated using a latent variable modeling approach.ResultsEach of the hypothesized models were a good fit for the data. As hypothesized, SES indirectly influenced postpartum smoking relapse through increased prepartum negative affect/stress, reduced sense of agency, and increased craving for cigarettes. However, the model that included craving as the sole final pathway between SES and relapse demonstrated superior fit when compared with all other models.ConclusionsFindings have implications for future interventions that aim to reduce postpartum relapse.

Mediators of the association of major depressive syndrome and anxiety syndrome with postpartum smoking relapse.

OBJECTIVE Based on conceptual models of addiction and affect regulation, this study examined the mechanisms linking current major depressive syndrome (MDS) and anxiety syndrome (AS) to postpartum smoking relapse. METHOD Data were collected in a randomized clinical trial from 251 women who quit smoking during pregnancy. Simple and multiple mediation models of the relations of MDS and AS with postpartum relapse were examined using linear regression, continuation ratio logit models, and a bootstrapping procedure to test the indirect effects. RESULTS Both MDS and AS significantly predicted postpartum smoking relapse. After adjusting for MDS, AS significantly predicted relapse. However, after adjusting for AS, MDS no longer predicted relapse. Situationally based self-efficacy, expectancies of controlling negative affect by means other than smoking, and various dimensions of primary and secondary tobacco dependence individually mediated the effect of both MDS and AS on relapse. In multiple mediation models, self-efficacy in negative/affective situations significantly mediated the effect of MDS and AS on relapse. CONCLUSIONS The findings underscore the negative impact of depression and anxiety on postpartum smoking relapse and suggest that the effects of MDS on postpartum relapse may be largely explained by comorbid AS. The current investigation provided mixed support for affect regulation models of addiction. Cognitive and tobacco dependence-related aspects of negative and positive reinforcement significantly mediated the relationship of depression and anxiety with relapse, whereas affect and stress did not. The findings emphasize the unique role of low agency with respect to abstaining from smoking in negative affective situations as a key predictor of postpartum smoking relapse.

Subjective social status predicts long-term smoking abstinence

BackgroundThe relationship between subjective social status (SSS), a persons perception of his/her relative position in the social hierarchy, and the ability to achieve long-term smoking abstinence during a specific quit attempt is unknown. The purpose of this study was to examine the relationship between SSS and long-term smoking abstinence among 421 racially/ethnically diverse smokers undergoing a specific quit attempt, as well as the interactive effects of race/ethnicity and sex.MethodsThe main effects and moderated relationships of SSS on biochemically-confirmed, continuous smoking abstinence through 26 weeks post-quit were examined using continuation ratio logit models adjusted for sociodemographics and smoking characteristics.ResultsEven after adjusting for the influence of socioeconomic status and other covariates, smokers endorsing lower SSS were significantly less likely to maintain long-term smoking abstinence during a specific quit attempt than those with higher SSS (OR = 1.14, 95% CI: 1.00 - 1.28; p = 0.044). The statistical significance of this relationship, however, did not vary by race/ethnicity or sex.ConclusionsSSS independently predicts long-term smoking abstinence during a specific quit attempt. SSS may be a useful screener to identify smokers at elevated risk of relapse who may require additional attention to facilitate long-term abstinence. More research is needed to understand the mechanisms underlying the relationship between SSS and long-term smoking abstinence in order to appropriately tailor treatment to facilitate abstinence among lower SSS smokers.

The role of prepartum motivation in the maintenance of postpartum smoking abstinence

OBJECTIVE Motivation plays an important role in a variety of behaviors, including smoking cessation, and is integral to theory and treatment of smoking. For many women, pregnancy offers a motivational shift that helps them stop smoking and maintain abstinence during pregnancy. However, womens motivation to maintain smoking abstinence postpartum is not well-understood and may play a role in high postpartum relapse rates. The current study utilized multiple measures of prepartum motivation to maintain smoking abstinence to predict postpartum smoking abstinence. METHODS As part of a randomized clinical trial on postpartum smoking relapse prevention, pregnant women who quit smoking during pregnancy reported their motivation to continue smoking abstinence at a prepartum baseline session. Biochemically verified continued smoking abstinence was assessed at 8 and 26 weeks postpartum. RESULTS Direct relationships among multiple measures of motivation were significant, and ranged in strength from weak to moderate. All motivation measures individually predicted continuous smoking abstinence, after controlling for treatment group, demographics, and prequit tobacco use. When tested simultaneously, a global motivation measure and parenthood motives for quitting remained significant predictors of abstinence. Backward selection modeling procedures resulted in a reduced model of prepartum predictors of postpartum abstinence including global motivation, parenthood motives, and stage of change. CONCLUSIONS Global motivation for smoking abstinence and parenthood motives for quitting are particularly important motivational constructs for pregnant womens continued smoking abstinence.

Differential Effects of Depression on Smoking Cessation in a Diverse Sample of Smokers in Treatment

BACKGROUND Recent cross-sectional evidence suggests that the effect of depression on smoking prevalence and quit ratios differs by race/ethnicity. PURPOSE This study prospectively examined the main and interactive effects of race/ethnicity and depressive symptoms on smoking cessation during a specific quit attempt among smokers receiving cessation treatment. METHODS Data from a longitudinal study of smokers in treatment were examined using continuation ratio logit modeling. Continuous abstinence across Weeks 1, 2, and 4 post-quit was the outcome variable. Data were collected between March 2005 and November 2007, and the current study analyses were conducted in April 2010. RESULTS Depressive symptoms predicted significantly lower cessation rates for whites and African Americans. In contrast, among Latinos there was no relationship between depression and cessation. CONCLUSIONS This research is the first to prospectively demonstrate a racially/ethnically differentiated effect of depressive symptoms on smoking cessation, and it has implications for targeted smoking-cessation treatments as it indicates that depression may not be a key treatment target for Latinos.

The influence of discrimination on smoking cessation among Latinos

BACKGROUND Although studies have shown a cross-sectional link between discrimination and smoking, the prospective influence of discrimination on smoking cessation has yet to be evaluated. Thus, the purpose of the current study was to determine the influence of everyday and major discrimination on smoking cessation among Latinos making a quit attempt. METHODS Participants were 190 Spanish speaking smokers of Mexican Heritage recruited from the Houston, TX metropolitan area who participated in the study between 2009 and 2012. Logistic regression analyses were conducted to evaluate the associations of everyday and major discrimination with smoking abstinence at 26 weeks post-quit. RESULTS Most participants reported at least some everyday discrimination (64.4%), and at least one major discrimination event (56%) in their lifetimes. Race/ethnicity/nationality was the most commonly perceived reason for both everyday and major discrimination. Everyday discrimination was not associated with post-quit smoking status. However, experiencing a greater number of major discrimination events was associated with a reduced likelihood of achieving 7-day point prevalence smoking abstinence, OR=.51, p=.004, and continuous smoking abstinence, OR=.29, p=.018, at 26 weeks post-quit. CONCLUSIONS Findings highlight the high frequency of exposure to discrimination among Latinos, and demonstrate the negative impact of major discrimination events on a smoking cessation attempt. Efforts are needed to attenuate the detrimental effects of major discrimination events on smoking cessation outcomes.
