Studies demonstrate a positive link between sugar-sweetened beverage (SSB) availability at home and school with increased intake for children across different ethnic groups. Given that SSB consumption per capita is disproportionately high among low-income American-born children; acculturation to the United States (U.S.) might moderate the relationship between food environment and soda consumption among low-income immigrant families. Thus, this study aims to analyze the effect of acculturation on the association between food environment and SSB consumption among parents and their preschoolers.
Baseline data from the Communities for Healthy Living project were used for this cross-sectional study. Families (N=348) were recruited from Head Start programs in the Greater Boston Area. One parent/caregiver (85% mothers) and one child aged 3-5 years per family participated. Parents reported on the availability of healthy and unhealthy foods in the home along with parent and child frequency of SSB consumption. Parents also reported their nativity, years in the United States, and primary language, which were used to create a composite score, following procedures outlined by Kandula et al. to denote acculturation. Acculturation was used as a moderator in two models. Parental education and age were used as covariates in all models. Ordinary Least Squares (OLS) regression was used to conduct analyses.
OLS regression results show significant associations between unhealthy food availability and greater SSB consumption of parents (β = 0.37, P = 0.001) and of children (β = 0.11, P = 0.001) as well as healthy food availability and lower SSB consumption of parents (β = -0.33, P = 0.001) and of children (β = -0.11, P = 0.02). However, after the addition of the two-way interaction term to the final OLS regression model, acculturation level did not significantly moderate the relationship between food availability and SSB consumption neither for parents nor for children.
Healthy food availability was associated with significantly low consumption of SSB in low-income parents and children. In our model, the level of acculturation did not moderate the relationship. Additional research is warranted to assess the role of acculturation in relation to food availability and SSB consumption among low-income families.
