To examine the association between sugar-sweetened beverage availability at home and sugar-sweetened beverage consumption, and to evaluate whether this association was consistent across school and school neighborhood sugar-sweetened beverage availability.

Secondary data analyses were performed from the 2014 cross-sectional, Internet-based Family Life, Activity, Sun, Health, and Eating (FLASHE) study of 1494 adolescents (age 12-17 years). Ordinal logistic regression analyses were conducted to examine the association between sugar-sweetened beverage availability in the home and adolescents' frequency of sugar-sweetened beverage consumption (nondaily, <1; daily, 1-<2; daily, ≥2), adjusting for adolescent age, sex, race, and body mass index and parent marital status and housing insecurity. Stratified ordinal logistic regression analyses were used to examine the associations by school and school neighborhood sugar-sweetened beverage availability.

One-third (32.6%) of adolescents were nondaily consumers of sugar-sweetened beverages, 33.9% consumed 1-<2 sugar-sweetened beverages daily, and 33.5% consumed ≥2 sugar-sweetened beverages daily. Almost one-half (44.4%) reported that sugar-sweetened beverages were often or always available in the home. Frequency of sugar-sweetened beverage availability at home was associated with greater sugar-sweetened beverage consumption (OR, 2.88; 95% CI, 2.86-2.89 for rarely/sometimes available at home; OR. 5.62; 95% CI, 5.60-5.64 for often/always available at home). Similar associations were found regardless of the availability of sugar-sweetened beverages in the adolescent's school or school neighborhood.

Sugar-sweetened beverage availability in the home was associated with adolescent sugar-sweetened beverage consumption, regardless of sugar-sweetened beverage availability in other settings, and may be a key target for obesity prevention efforts.
