Among infants, approximately 14% to 26% consume SSBs during the first year of life, leading to a 2-fold higher odds of obesity at age 6 years compared with counterparts with no SSB intake. This study assessed the relationship between parental sugar-sweetened beverage (SSB) attitudes and SSB consumption during the first 1,000 days in Hispanic/Latino families. Higher parental SSB attitudes scores were associated with lower parental SSB consumption and linked with lower odds of infant SSB consumption. These results highlight the importance of parental SSB attitudes in the development of future interventions to decrease SSB intake during pregnancy and infancy.
