Objective: Intimate partner violence (IPV) is a serious public health concern that affects many Latinx couples. The present study conducted a systematic review and meta-analysis to quantitatively assess acculturation as a predictor of IPV among Latinxs and subgroup analyses to evaluate the effect size by gender and type of acculturation measure. Method: The meta-analysis implemented the preferred reporting items for systematic reviews and meta-analyses guidelines to retrieve studies assessing the relationship between acculturation and intimate partner victimization among foreign-born and U.S.-born Latinx adults. A fixed effects model (FEM) and a random effects model (REM) were employed. Additional subgroup analyses examined the strength of the relationship by gender and type of acculturation measure. Results: The meta-analysis included 27 independent effect sizes across 21 studies. An REM yielded a weighted average correlation of .11 (95% confidence interval [.02, .20]). The strength of the correlation differed by scale and ranged from −.003 to .47. For both men and women, higher acculturation was associated with increased IPV. Conclusions: Our results yielded three important findings: (1) the overall effect of acculturation on IPV is relatively small, (2) acculturation differentially influences male-to-female and female-to-male partner violence, and (3) the strength of the correlation between acculturation and IPV differs by scale. This body of work provides evidence for the effect of acculturation on IPV, with potential implications for interventions targeting Latinxs.

Research on health among Latinos often focuses on acculturation processes and the associated stressors that influence drinking behavior. Given the common use of acculturation measures and the state of the knowledge on alcohol-related health among Latino populations, the current analyses tested the efficacy of acculturation measures to predict various indicators of alcohol consumption. Specifically, this quantitative review assessed the predictive utility of acculturation on alcohol consumption behaviors (frequency, volume, and quantity). Two main analyses were conducted-a p-curve analysis and a meta-analysis of the observed associations between acculturation and drinking behavior. Results demonstrated that current measures of acculturation are a statistically significant predictor of alcohol use (Z = -20.75, p < 0.0001). The meta-analysis included a cumulative sample size of 29,589 Latino participants across 31 studies. A random-effects model yielded a weighted average correlation of 0.16 (95% confidence interval = 0.12, 0.19). Additional subgroup analyses examined the effects of gender and using different scales to measure acculturation. Altogether, results demonstrated that acculturation is a useful predictor of alcohol use. In addition, the meta-analysis revealed that a small positive correlation exists between acculturation and alcohol use in Latinos with a between-study variance of only 1.5% (τ = 0.015). Our analyses reveal that the association between current measures of acculturation and alcohol use is relatively small.

Background: Past research has focused on understanding influenza vaccine acceptance in non-Hispanic white populations; however, research on the social causes of influenza vaccine acceptance rates in Hispanic populations is slowly developing. Objective: The purpose of this study was to assess theoretically driven predictors (i.e. attitudes, perceptions, behaviors, etc.) on influenza and the intention to vaccinate. Methods: A survey was administered to assess predictors of intentions to receive the influenza vaccine. The survey included items adapted from the National Flu Survey. Results: Key constructs common in models of health behaviors emerged as predictors of behavioral intentions to receive the flu vaccine. Recent vaccination within the past year ( P < 0.001), perceived effectiveness of the flu vaccine ( P < 0.004), and perceived safety of the flu vaccine ( P = 0.009) were predictors of intentions to vaccinate. Exploratory analyses revealed that government distrust was a statistically significant predictor of intentions to vaccinate ( P = 0.044). Conclusion: The above results have important implications for health-care providers and public health educators. The better we understand the relationship between theoretically driven predictors and vaccine behaviors, the more educators and health-care providers can focus on meaningful, culturally sensitive, targeted-vaccine education.

While the cognitive enhancing effects of nicotine use have been well documented, it has also been shown to impair decision making. The goal of this study was to determine if exposure to nicotine vapor increases risky decision making. The study also aims to investigate possible long-term effects of nicotine vapor exposure on the expression of genes coding for cholinergic and dopaminergic receptors in brain. Thirty-two adult male Sprague Dawley rats were exposed to 24 mg/mL nicotine vapor or vehicle control, immediately followed by testing in the probability discounting task for 10 consecutive days. Fifty-four days after the 10-day vapor exposure, animals were sacrificed and expression of genes coding for the α4 and β2 cholinergic receptor subunits, and dopamine D1 and D2 receptors, were analyzed using RT-PCR. Exposure to nicotine vapor caused an immediate and transient increase in risky choice. Analyses of gene expression identified significant reductions in CHRNB2 and DRD1 in the nucleus accumbens core and CHRNB2 and DRD2 in the medial prefrontal cortex of rats previously exposed to nicotine vapor, relative to vehicle controls. Results provide data on the negative cognitive effects of nicotine vapor exposure and identify cholinergic and dopaminergic mechanisms that may affected with repeated use.
