RESUMO
OBJECTIVES: To determine whether early diet and weight gain velocity have independent or interactive effects on deciduous teeth emergence and overweight status during the first year. STUDY DESIGN: Monthly measures of anthropometry and teeth eruption were collected during a 1-year trial (0.5-12.5 months) on formula-fed infants in which the type of randomized infant formula (cow milk or extensively hydrolyzed protein) diet significantly affected early (0.5-4.5 months) weight gain velocity. Generalized linear mixed models determined whether early diet and weight gain velocity had independent or interactive effects on timing and pattern of teeth eruption. Data from a trial on breastfed infants were used to explore effects of breast milk vs infant formula diets on teeth eruption and overweight status at 10.5 months. RESULTS: Independent of infant formula diet, velocities of weight gain had direct effects on the age of first deciduous tooth (P < .04) and number of erupted teeth over time (P < .002). Greater velocity of weight gain from 0.5 to 4.5 months caused earlier and more frequent eruption of deciduous teeth from 4.5 to 12.5 months. Exploratory follow-up analyses on the breastfed and formula-fed diet groups found early weight gain velocity (P = .001), but not diet or its interaction, had significant effects. Infants in the upper quartile for weight gain velocity had more primary teeth (P = .002), and a greater proportion of them were overweight (P < .001) at 10.5 months. CONCLUSIONS: Faster weight gain accretion forecasted accelerated primary teeth eruption and increased percentage of children who were overweight-risk factors for dental caries and obesity.

BACKGROUND: Child maltreatment is a significant public health issue in the United States. Yet, fewer than half of pediatricians discuss behavioral, developmental, or parenting issues with parents. OBJECTIVE: This paper describes the testing of bundles of tools and processes, part of a larger intervention, Practicing Safety, targeted at changing physician and staff behavior to identify families at risk for child maltreatment, provide anticipatory guidance, refer to community resources, and follow-up and track at-risk families. The intervention was implemented with 14 pediatric primary care practices throughout the United States; the study was completed in 2011. METHODS: A within-subjects repeated measures pre-post follow-up design was used to evaluate the intervention. Baseline and repeated measurements of pediatric practices' processes were collected using qualitative and quantitative methods. In total, 14 core improvement teams from across the country tested three bundles of tools (maternal, infant, toddler) within a quality improvement framework over seven months. RESULTS: Quantitative results showed statistically significant adoption of tools and processes and enhancement of practice behaviors and office environmental supports. The increase in tool use was immediate and was sustained for six months after implementation. Qualitative data provided insight as to how meaningful the intervention was to the core improvement teams, especially with more complicated behaviors (eg, engaging social workers or community agencies for referrals). Barriers included lack of community resources. Findings showed unanticipated outcomes such as helping practices to become medical homes. CONCLUSION: Lessons learned included that practices appreciate and can adopt brief interventions that have meaningful and useful tools and process to enhance psychosocial care for children 0-3 and that do not place a burden on pediatric practice. An innovative, quality improvement strategy, intuitive to pediatricians, with a brief intervention may help prevent child maltreatment.
