Examining Determinants and Co-associations Between Fruit and Vegetable and Sugar-Sweetened Beverage Monitoring Practices Among a Sample of Low-Income Hispanic Mothers.

The etiology of obesity is complex, and a growing body of research suggests that changing two or more behaviors at the same time will likely have a stronger impact than changing one behavior in isolation. A lack of fruit and vegetable (FV) intake and high sugar-sweetened beverage (SSB) consumption are two behaviors related to childhood obesity in the Hispanic community. The purpose of this study was to evaluate theory-based determinants of monitoring practices of FV and SSB among Hispanic mothers with young children using the reasoned action approach. The study also examined the co-associations among the theoretical antecedents for both behaviors. Surveys were distributed in several community settings to urban Hispanic mothers (n = 238) of 2-5-year-old children. Surveys assessed FV and SSB monitoring practices, attitudes, perceived norms, perceived behavioral control (PBC), and intentions. Two models were evaluated using structural equation modeling: attitudes, perceived norms, and PBC of both behaviors were associated with intentions for both behaviors, and PBC and intentions were associated with monitoring practices of FV and SSB. Both models had adequate fit (FV (CFI = 0.973; GFI = 0.980; RMSEA = 0.121); SSB (CFI = 0.994; GFI = 0.993; RMSEA = 0.066)). PBC for both FV and SSB monitoring was significantly associated with SSB monitoring, whereas FV intentions was only significantly associated with FV monitoring. Results from this study gives evidence that among Hispanic mothers, FV and SSB monitoring behaviors are interrelated. To promote SSB monitoring, more implementation strategies (i.e., skills-based interventions) are warranted, whereas to promote FV monitoring, motivational strategies are warranted.
