The marketing of Sugar-Sweetened Beverages (SSBs) within grocers is an obesogenic factor that negatively impacts children's nutritional behavior, specifically for people from racial and ethnic minority groups, such as immigrants. We aimed to develop and employ a methodology that more precisely assesses the availability, price, and promotion of SSBs to young immigrant children within independently owned grocery stores. A case comparison design was used to explore the differences in the grocery store landscape of SSB marketing by conducting an enhanced Nutrition Environment Measures Survey-SSB (NEMS-SSB) within 30 grocery stores in the Hispanic and Latino enclaves in Southwest Detroit, in the Arab and Chaldean enclaves in North-central Detroit, and in Warren, Hamtramck, and Dearborn, in comparison with 48 grocers in Metro Detroit. Unsweetened, plant-based, and organic toddler and infant beverages, as well as questions about marketing, were added to the original NEMS to capture the promotion tactics used in marketing SSBs. NEMS-SSB scores revealed that, in the immigrant enclaves, there was a significantly higher availability of SSBs in grocery stores (-2.38), and they had lower prices than those in the comparison group (-0.052). Unsweetened, plant-based, and organic beverages were unavailable in 97% of all participating grocery stores across both groups. Signage featuring cartoon characters was the most frequent in-store SSB marketing tactic across both groups. Widespread SSB marketing toward toddlers within the grocery stores in immigrant enclaves could be linked with the higher early childhood obesity prevalence among the immigrant population. Our findings can assist local and national organizations in developing and implementing healthy eating interventions. This study must be repeated in other immigrant enclaves across states to provide comparable results.
