A cross-lagged path analysis of five intrapersonal determinants of smoking cessation

Background: Prominent theories of drug use underscore the importance of considering the inter-relationships (e.g., reciprocal relations, indirect effects) of determinants of drug use behavior. In the area of smoking, few studies have examined multiple determinants of cessation in this way, and in prospective analyses. The current study is an examination of the prospective cross-lagged relationships among five intrapersonal determinants of cessation. Methods: Data from a longitudinal cohort study on racial differences in the process of smoking cessation were used to examine reciprocal relations among abstinence motivation, abstinence self-efficacy, positive affect, negative affect, and craving. Each of these five measures assessed on the quit day were regressed onto the same measures assessed 1–2 weeks pre-quit. The relationships of these variables at quit day with 1-week post-quit abstinence from smoking were also examined. Results: When the five variables were examined simultaneously in a cross-lagged path analysis, motivation and self-efficacy, and self-efficacy and positive affect showed cross-lagged relations. Only self-efficacy on the quit day uniquely predicted 1-week post quit abstinence. There were significant indirect effects of motivation and positive affect on cessation via self-efficacy. Conclusions: The current study reaffirms the importance of motivation and self-efficacy in smoking cessation, and suggests that positive affect may play a role in smoking cessation

Acculturative and neighborhood influences on subjective social status among Spanish-speaking Latino immigrant smokers

Subjective social status (SSS) reflects an individual's perception of her/his relative position in the social hierarchy. However, little is known about culturally-relevant, multilevel predictors of low SSS among low socioeconomic status (SES), minority populations. The goal of this study was to identify individual- and neighborhood-level variables predicting SSS among 297 Spanish-speaking Latino immigrant smokers living in several locations in Texas, with an emphasis on the association of SSS with acculturative and socioeconomic variables. Participants were recruited and enrolled through the National Cancer Institute's Cancer Information Service from August 2002 to March 2004. Determinants of SSS were explored using a series of linear regressions. In analyses adjusting for demographics (including objective indicators of SES), speaking Spanish at home and work and living in economically disadvantaged neighborhoods, respectively, were associated with low SSS. However, in analyses including demographics, acculturation, and neighborhood characteristics, only income, education, and acculturation remained associated with SSS. Consistent with results from a previous study in the area (Franzini & Fernandez-Esquer, 2006), less acculturation predicted low SSS among immigrant Latino smokers. However, unlike previous research, these associations were maintained after controlling for SES. Results suggest that the density of less acculturated Latinos within economically deprived neighborhoods might account for the disappearance of neighborhood effects in the final model.Latinos Social status Acculturation Neighborhood Immigrants USA Smoking

Pathways between socioeconomic status and modifiable risk factors among African American smokers

Tema rada je iz dostupnih demografskih i ekonomskih pokazatelja zemalja te uspjeha na Olimpijskim igrama u Riju 2016. izraditi regresijski model koji će se kasnije moći koristiti u predikcijske svrhe. Kako bi se to postiglo prvo se definiraju pojmovi korelacije i regresije te se detaljnije obrađuju jednostavna i višestruka regresija. Pokazuje se koliko transformacija varijabli može povećati točnost predikcije te se definiraju kriteriji koji će biti važni prilikom odabira najboljeg regresijskog modela. Definiraju se odabrani ekonomski i demografski pokazatelji te način na koji se mjeri uspjeh pojedine države na Olimpijskim igrama 2016. godine. Nakon raznih testiranja odabran je najreprezentativniji regresijski model na temelju kojeg je napravljena prognoza rezultata za sljedeće Olimpijske igre koje će se održati 2020. godine u Tokiju

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
