A Digital Health Behavior Intervention to Prevent Childhood Obesity: The Greenlight Plus Randomized Clinical Trial.

Importance: Infant growth predicts long-term obesity and cardiovascular disease. Previous interventions designed to prevent obesity in the first 2 years of life have been largely unsuccessful. Obesity prevalence is high among traditional racial and ethnic minority groups.

A Randomized Trial of Inspiratory Training in Children and Adolescents With Obesity.

Children with obesity suffer excess dyspnea that contributes to sedentariness. Developing innovative strategies to increase exercise tolerance and participation in children with obesity is a high priority. Because inspiratory training (IT) has reduced dyspnea, we sought to assess IT in children with obesity.

Exploring the Feasibility and Acceptability of Providing Caregivers Who Formula-feed with Smaller Infant Bottles in a Primary Care Clinic.

Objectives: Larger bottle size is associated with faster weight gain in infants, but little is known about acceptability and feasibility of providing bottles in primary care clinics.

Methods: We randomized parent-infant dyads (N = 40) to receive a set of 4-ounce bottles or to continue using their own bottles. Demographic and anthropometric information were collected at enrollment and one follow-up visit 1-5 months later.

Infant Television Watching Predicts Toddler Television Watching in a Low-Income Population.

Objective: This study examines the development of active television (TV) watching behaviors across the first 2 years of life in a racially and ethnically diverse, low-income cohort and identifies caregiver and child predictors of early TV watching.

Methods: We used longitudinal data from infants enrolled in the active control group (N = 235; 39% Latino; 29% Black; 15% White) of Greenlight, a cluster randomized multisite trial to prevent childhood obesity. At preventive health visits from 2 months to 2 years, caregivers were asked: "How much time does [child's first name] spend watching television each day?" Proportional odds models and linear regression analyses were used to assess associations among TV introduction age, active TV watching amount at 2 years, and sociodemographic factors.

A randomized controlled trial examining an exam room poster to prompt communication about weight.

Background: Recognition of childhood weight status is important to the adoption of healthy lifestyle behaviours.

Objectives: We assessed whether an exam room educational poster addressing weight and healthy lifestyle behaviours was acceptable to parents, prompted parent-provider communication or improved parental weight perception accuracy.

Methods: In this multi-site randomized controlled trial, exam rooms were randomized to display the posters (English and Spanish) or not.

Concordance of Child and Parent Reports of Children's Screen Media Use.

Objective: Little is known about the concordance of parent and child reports of children's media consumption, even though parents are often asked to report for their children in clinical care settings. Our objective was to understand how parent and child reports of children's media consumption differ in an era of changing screen media consumption via personal devices.

Methods: As part of a larger study about the reception of health-related cues from children's media, children ages 9 to 11 years (N = 114) and their parents independently completed identical questionnaires about specific media use and health behaviors.

Obesogenic Behavior and Weight-Based Stigma in Popular Children's Movies, 2012 to 2015.

Background: Obesity-promoting content and weight-stigmatizing messages are common in child-directed television programming and advertisements, and 1 study found similar trends in G- and PG-rated movies from 2006 to 2010. Our objective was to examine the prevalence of such content in more recent popular children's movies.

Methods: Raters examined 31 top-grossing G- and PG-rated movies released from 2012 to 2015.

Implicit Weight Bias in Children Age 9 to 11 Years.

Objectives: Assess implicit weight bias in children 9 to 11 years old.

Methods: Implicit weight bias was measured in children ages 9 to 11 ( = 114) by using the Affect Misattribution Procedure. Participants were shown a test image of a child for 350 milliseconds followed by a meaningless fractal (200 milliseconds), and then they were asked to rate the fractal image as "good" or "bad.

Influence of product placement in children's movies on children's snack choices.

Background: Media exposure affects health, including obesity risk. Children's movies often contain food placements-frequently unhealthy foods. However, it is not known if these cues influence children's food choices or consumption after viewing.
