    Association of the ALDH1A1*2 promoter polymorphism with alcohol phenotypes in young adults with or without ALDH2*2
    (Wiley, 2013) Otto, Jacqueline M.; Hendershot, Christian S.; Collins, Susan E.; Liang, Tiebing; Wall, Tamara L.; Medicine, School of Medicine
    Background: Prior studies suggest a possible association of a promoter polymorphism in the ALDH1A1 gene ( ALDH1A1*2 ) with alcohol use or dependence. The aim of this study was to examine the association of ALDH1A1*2 with drinking behaviors in Asian young adults and to examine ALDH2 genotype as a potential moderator of these associations. Methods: Asian young adults (n = 951) were recruited from 2 college sites for studies of genetic associations with alcohol use behavior. Participants completed comprehensive background questionnaires on demographics and drinking behavior. Fingertip blood samples were obtained for DNA extraction and analysis. Results: Participants with the ALDH2*1/*2 genotype reported significantly lower levels (frequency and quantity) of drinking within the last 90 days, fewer numbers of heavy drinking episodes within the last 90 days, and lower lifetime maximum consumption levels compared with ALDH2*1/*1 participants. There were no significant main effects of ALDH1A1*2 on any drinking variables, nor was there a significant interaction between ALDH2 and ALDH1A1 genotypes on drinking outcomes. Conclusions: The association of ALDH2*2 with reduced alcohol consumption replicates previous findings across numerous studies. Although ALDH1A1*2 was not associated with drinking levels, the lack of an ALDH1A1*2 effect in ALDH2*2 individuals is consistent with the only other study that has examined these associations in East Asian populations.

    Food Insecurity and Sugar-Sweetened Beverage Consumption Among WIC-Enrolled Families in the First 1,000 Days
    (Elsevier, 2020-08) Fernández, Cristina R.; Chen, Ling; Cheng, Erika R.; Charles, Nalini; Meyer, Dodi; Monk, Catherine; Woo Baidal, Jennifer; Pediatrics, School of Medicine
    Objective: Determine the association between household food insecurity and habitual sugar-sweetened beverage (SSB) consumption among Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)-enrolled families during the first 1,000 days. Methods: Cross-sectional analysis of pregnant women and mothers of infants aged under 2 years in the WIC was performed. Families recruited sequentially at consecutive visits completed food insecurity and beverage intake questionnaires; estimated logistic regression models controlled for sociodemographic characteristics. Results: Of 394 Hispanic/Latino mothers and 281 infants, 63% had household food insecurity. Food insecurity significantly increased odds of habitual maternal (unadjusted odds ratio (OR), 2.39; 95% CI, 1.27-4.47; P = .01) and infant SSB consumption (OR, 2.05; 95% CI, 1.15-3.65; P = .02), and the relationship was not attenuated by maternal age, education, or foreign-born status. Conclusions and implications: Food insecurity increased odds of habitual SSB consumption in WIC families. Interventions to curb SSB consumption among WIC-enrolled families in the first 1,000 days in the context of household food insecurity are needed.
