Vida PURA: results from a pilot randomized trial of a culturally adapted screening and brief intervention to reduce unhealthy alcohol use among Latino day laborers.

Latino immigrant men are at increased risk for unhealthy alcohol use. Vida PURA is a culturally adapted evidence-based intervention that consists of promotores providing screening and brief intervention to reduce unhealthy alcohol use among Latino immigrant men. The purpose was to assess the efficacy of Vida PURA in a pilot randomized control trial. Participants were screened for eligibility at a day labor worker center using the Alcohol Use Disorders Identification Test (AUDIT). Those with an AUDIT score ≥ 6 (N = 121) were randomized into an intervention (N = 77) or control group (N = 44). Participants in the intervention group received a brief intervention from a promotor including personalized feedback, motivational interviewing to assess their readiness to change, and referral to services. Participants in the control group received information about local substance use treatment services. We assessed changes in AUDIT scores, drinks per drinking day, drinking days, and frequency of heavy episodic drinking at 2 and 8 weeks following the baseline survey using a mixed-effects regression model. Many men had high AUDIT scores, indicating dependence. Both the intervention and control groups reduced their alcohol-related behaviors over time, but there were no significant differences between the groups. A culturally adapted brief intervention may not be enough to significantly reduce alcohol use among Latino day laborers, especially among those that are dependent. We discuss lessons learned from this trial, including the value of community-based approaches to reaching high-risk and underserved populations.

Vida PURA: An assessment of the fidelity of promotor-delivered screening and brief intervention to reduce unhealthy alcohol use among Latino day laborers.

We assessed the fidelity of promotores conducting screening and brief intervention (SBI) to reduce unhealthy alcohol use among Latino immigrant day laborers in the Vida PURA study. We reviewed 32 audio-recorded brief interventions to assess promotor adherence to the intervention protocol and to evaluate their motivational interviewing (MI) technique with the Motivational Interviewing Treatment Integrity (MITI) 4.2.1 tool. Promotores delivered three core intervention steps in 78% of recordings and achieved basic MI competence across all domains and proficiency in 50% of measures. Our results suggest that promotores can be trained to deliver SBI in community settings with fidelity.

Patterns of Unhealthy Alcohol Use among Latino Day Laborers.

Objective: We sought to describe patterns of unhealthy alcohol use among Latino immigrant day laborers and identify correlates of these behaviors. Methods: Participants (N = 104) completed surveys on substance use, alcohol-related problems, mental health, and demographics. We assessed differences in unhealthy alcohol use by subject characteristic using chi-square tests of independence and 2-sample tests of proportions. Results: Unhealthy alcohol use was common with 65% having an AUDIT score of 8 or higher. Living situation and income were significantly associated with unhealthy alcohol use and high levels of depression and anxiety were associated with increased alcohol-related problems. Conclusions: Interventions to reduce unhealthy alcohol use should consider the role of stable housing, income and mental health.

Dietary phthalate exposure in pregnant women and the impact of consumer practices.

Phthalates are ubiquitous endocrine-disrupting chemicals that are contaminants in food and contribute to significant dietary exposures. We examined associations between reported consumption of specific foods and beverages and first trimester urinary phthalate metabolite concentrations in 656 pregnant women within a multicenter cohort study, The Infant Development and Environment Study (TIDES), using multivariate regression analysis. We also examined whether reported use of ecofriendly and chemical-free products was associated with lower phthalate biomarker levels in comparison to not following such practices. Consumption of one additional serving of dairy per week was associated with decreases of 1% in the sum of di-2-ethylhexyl phthalate (DEHP) metabolite levels (95% CI: -2.0, -0.2). Further, participants who reported sometimes eating homegrown food had monoisobutyl phthalate (MiBP) levels that were 16.6% lower (95% CI: -29.5, -1.3) in comparison to participants in the rarely/never category. In contrast to rarely/never eating frozen fruits and vegetables, participants who reported sometimes following this practice had monobenzyl phthalate (MBzP) levels that were 21% higher (95% CI: 3.3, 41.7) than rarely/ever respondents. Future study on prenatal dietary phthalate exposure and the role of consumer product choices in reducing such exposure is needed.

Phthalates and diet: a review of the food monitoring and epidemiology data.

Phthalates are associated with a variety of health outcomes, but sources that may be targeted for exposure reduction messaging remain elusive. Diet is considered a significant exposure pathway for these compounds. Therefore, we sought to identify primary foods associated with increased exposure through a review of the food monitoring survey and epidemiological data. A search in PubMed and Google Scholar for keywords "phthalates" and "diet" "food" "food stuffs" "dietary intake" "food intake" and "food concentration" resulted in 17 studies measuring phthalate concentrations in United States (US) and international foods, three epidemiological association studies, and three interventions. We report on food groups with high (≥300 µg/kg) and low (<50 µg/kg) concentrations and compare these to foods associated with phthalate body burden. Based on these data, we estimated daily intakes of di-2-ethylhexyl phthalate (DEHP) of US women of reproductive age, adolescents and infants for typical consumption patterns as well as healthy and poor diets. We consistently observed high DEHP concentrations in poultry, cooking oils and cream-based dairy products (≥300 µg/kg) across food monitoring studies. Diethyl phthalate (DEP) levels were found at low concentrations across all food groups. In line with these data, epidemiological studies showed positive associations between consumption of meats, discretionary fat and dairy products and DEHP. In contrast to food monitoring data, DEP was found to be associated with intake of vegetables in two studies. DEHP exposure estimates based on typical diets were 5.7, 8.1, and 42.1 µg/kg-day for women of reproductive age, adolescents and infants, respectively, with dairy as the largest contributor to exposure. Diets high in meat and dairy consumption resulted in two-fold increases in exposure. Estimates for infants based on a typical diet exceeded the Environmental Protection Agency's reference dose of 20 µg/kg-day while diets high in dairy and meat consumed by adolescents also exceeded this threshold. The review of the literature demonstrated that DEHP in some meats, fats and dairy products is consistently found in high concentrations and can contribute to exposure. Guidance on future research in this area is provided that may help to identify methods to reduce dietary phthalate exposures.
