To determine risk factors for consumption of soda and other sugar-sweetened beverages (SSB) among 2-year-old children.
The analysis was performed using three linked data sets: the 2004–2005 Oregon Pregnancy Risk Assessment Monitoring Survey (PRAMS); its longitudinal follow-up, 2006–2007 Oregon PRAMS-2; and 2004–2005 Oregon birth certificates.
PRAMS is a surveillance programme supported by the federal Centers for Disease Control and Prevention and implemented by participating state health departments. Using mixed methods, PRAMS surveys women 2–6 months after a live birth. Oregon PRAMS-2 re-interviews respondents shortly after the index child's second birthday. Oregon PRAMS oversamples minority women.
Using monthly cohorts, we randomly selected 5851 women from the 2004–2005 birth certificates. In total 1911 women completed both PRAMS and PRAMS-2. The weighted response rate of PRAMS-2 was 43·5 %.
Almost half of mothers (49·9 %) reported that their child drank SSB on at least 1 d/week. Mothers whose children drank SSB at least once weekly were more likely to have low income (adjusted OR = 2·83, 95 % CI 2·09, 3·83) and to eat out on ≥2 d/week (OR = 2·11 %, 95 % CI 1·66, 2·70). Hispanic and non-Hispanic black women were most likely to report that their child drank SSB at least once weekly.
Half of mothers reported that their 2-year-old children drank SSB at least once weekly. Public health interventions and policies should address childhood SSB consumption including educating health-care providers and parents.
