Brief Summary:
The aim of the proposed study is to assess the efficacy of a low-literacy/numeracy-oriented intervention to promote healthy lifestyles and preventing obesity among young children in under-resourced communities. The study will occur in pediatric resident physician care practices since nationally, resident practice sites provide care to more than one-fifth of the socioeconomically disadvantaged families in the US.

Arm Intervention/treatment
Active Comparator: Control "Attention" Intervention
This injury prevention program will act as an "attention placebo" to control against the added attention provided to the intervention group. In addition this injury prevention program will act as an incentive for Pediatric Resident Clinics to participate and maximize retention throughout the study period - as they will know that they will be randomized to one of two beneficial resident education programs.
Behavioral: Control Group
In contrast to the Intervention study, NO training in communication skills will be provided, and NONE of the nutrient/physical activity oriented educational materials will be provided to the Control groups.

Experimental: Greenlight Intervention
The intervention includes the following components: (1) training of pediatric resident physicians in improved health communication skills and (2) a low literacy and numeracy-oriented educational toolkit which promotes healthy diet and physical activity practices.
Behavioral: Greenlight Intervention
The GREENLIGHT Tool Kit will use low-literacy handouts and study-related "gifts" to assess nutrition and physical activity behaviors, and reinforce evidence-based recommendations about early childhood nutrition and physical activity.

Primary Outcome Measures :
  1. Proportion of children at age 24 months who are not overweight [ Time Frame: 24 Months ]
    (defined as BMI <85 percentile for age and gender per the 2000 CDC Growth Charts for Children Age 0-2, and recent Expert Panel Consensus definitions of overweight and obese).

Secondary Outcome Measures :
  1. Weight status of children at 5 years of age [ Time Frame: 5 Years ]
    determined by BMI z-score. BMI z-scores are standardized for BMI percentile, adjusted for age and gende
