Effects of a federal housing voucher experiment on adolescent binge drinking: a secondary analysis of a randomized controlled trial.

ABSTRACT: AIMS:To test how a housing voucher generating residential mobility to lower-poverty neighborhoods, compared with public housing controls, influenced adolescent binge drinking, and whether gender modified effects. DESIGN:A multi-site household-level three-arm randomized trial of a housing intervention executed 1994-98, evaluated 2001-02. SETTING:Five US cities: Baltimore, MD; Boston, MA; Chicago, IL; Los Angeles, CA; and New York, NY. PARTICIPANTS:A total of 3537 adolescents in 4248 low-income eligible families were randomized; 2829 adolescents were analyzed at the interim evaluation (1950 in treatment; 879 in the control group). Attrition bias was accounted for with a 3-in-10 oversampling of hard-to-reach participants (effective response rate: 89%). INTERVENTIONS:The Moving to Opportunity (MTO) trial randomized volunteer low-income families in public housing to receive (1) rental subsidies redeemable in neighborhoods with < 10% tract poverty plus housing counseling, (2) unrestricted Section 8 rental subsidies or (3) to remain in public housing. We pooled the subsidy ('treatment') groups because they were conceptually similar and there was no evidence of statistical differences between groups on binge drinking. MEASUREMENTS:Primary outcome: past month binge drinking (five or more drinks in one sitting). FINDINGS:Adolescent binge drinking prevalence was 3.9% for treatment and 3.2% for control. The intention-to-treat (ITT) main effect of subsidy treatment (versus control) on binge drinking was non-significant, but treatment effects were different for girls and boys (treatment-gender interaction P = 0.002). MTO treatment reduced girls' binge drinking [odds ratio (OR) = 0.48, 95% confidence interval (CI) = 0.24-0.96, P = 0.037], but increased boys' binge drinking (OR = 2.37, 95% CI = 1.13-4.97, P = 0.023), compared with controls. Results were similar for secondary alcohol outcomes. Instrumental variable (IV) results adjusting for treatment compliance were comparable with ITT, but larger. CONCLUSIONS:A housing subsidy treatment that enables low-income families to move from public to private housing appears to lessen girls' binge drinking but increases boys' binge drinking, compared with controls.

Project description:The objective of this study was to determine changes in gene expression within the extended amygdala following binge-like alcohol drinking by adolescent alcohol-preferring (P) rats. Starting at 28 days of age, P rats were given concurrent access to 15 and 30 % ethanol for 3 one-h sessions for 5 consecutive days each week until they were 49 days old. Rats were killed by decapitation 3 h after the first ethanol access session on the 15th day of drinking. RNA was prepared from micropunch samples of the nucleus accumbens shell (Acb-sh) and central nucleus of the amygdala (CeA). Ethanol intakes were 2.5 to 3.0 g/kg/session. There were 154 and 182 unique named genes that significantly differed (FDR = 0.2) between the water and ethanol group in the Acb-sh and CeA, respectively. Gene Ontology (GO) analyses indicated that adolescent binge drinking produced changes in the in biological processes involved in cell proliferation and regulation of cellular structure in the Acb-sh, and in neuron projection and positive regulation of cellular organization in the CeA. Ingenuity Pathway Analysis indicated that, in the Acb-sh, there were several major intracellular signaling pathways (e.g., cAMP-mediated and protein kinase A signaling pathways) altered by adolescent drinking, with 3-fold more genes up-regulated than down-regulated in the alcohol group. The cAMP-mediated signaling system was also up-regulated in the CeA of the alcohol group. Weighted gene co-expression network analysis (WGCNA) indicated significant G-protein coupled receptor signaling and transmembrane receptor protein kinase signaling categories in the Acb-sh and CeA, respectively. Overall, the results of this study indicated that binge-like alcohol drinking by adolescent P rats is differentially altering the expression of genes in the Acb-sh and CeA, some of which are involved in intracellular signaling pathways and may produce long-term changes in neuronal function. Differences in gene expression in the central nucleus of the amygdala (CeA) were compared in two groups of alcohol-preferring (P) rats, one given water only and the other given access to 15 & 30% ethanol during adolescence.
