Community-based sugar-sweetened beverage intervention associated with short-term improvements in self-rated oral...

To assess the efficacy of a community-based childhood obesity prevention intervention targeting Sugar-sweetened beverage (SSB) consumption on self-rated oral health among children and their parents/caregivers.

This study is a secondary analysis of data from a pilot site-randomized intervention (H₂ GO!) targeting SSB consumption and obesity risk among children. The 6-week SSB behavioural intervention was implemented in two Massachusetts Boys and Girls Club sites that were matched for size and racial/ethnic composition. Children ages 9-12 years and their parents/caregivers were eligible to participate. Data on self-rated oral health and sociodemographics were obtained via self-report surveys at baseline, 2 and 6 months. Generalized linear mixed regression models were used to estimate 2- and 6-month change in oral health associated with the intervention.

Data are from 100 child participants (46% female; 38% Black, 20% Hispanic, 13% White, 12% Multiracial, 11% Asian) and 87 parent participants (78.2% female; 37.9% Hispanic, 29.9% Black, 14.9% Asian, 10.3% White). At baseline, 47% of child participants rated their oral health as good, followed by very good (32%), fair (11%) and excellent (10%). Among parents, 46.3% rated their oral health as good, followed by very good (29.3%), excellent (9.8%), fair (9.7%) and poor (4.9%). The intervention was associated with 2- and 6-month improvements in child participants' mean self-rated oral health scores (β = 0.78; 95% CI: 0.48, 1.087; P < .001; β = 0.98; 95% CI: 0.61, 1.34; P < .001, respectively) and with 2-month improvements in parent participants' mean self-rated oral health (β = 0.42; 95% CI: 0.016, 0.82; P = .042).

Short-term improvements in oral health among children and their parents/caregivers were observed among those participating in a SSB behavioural intervention. Community-based behavioural programmes targeting SSB consumption may be a promising approach to promote oral health as well as prevent childhood obesity.
