Patient-Clinic-Community Integration to Prevent Obesity Among Rural Preschool Children

BMI values will be obtained from Geisinger clinical care visits, documented in the EHR and standardized or parent-reported. Values obtained at well child visits during the study period, ideally 12 months, 1 day apart will be utilized but values within a 9- to 18-month span of baseline to 1-year follow up may be used (e.g., 3 months pre-baseline WCV to 15 months post-baseline, baseline WCV to 18-months post-baseline, etc.) to assess the primary outcome. A z-score of 0 represents the population mean. Higher z-scores represent worse outcomes. BMI z-score over >=1 indicates possible risk for overweight.

This questionnaire uses 6 items to provide a scale of food security of high food security to very low food security. Scoring: Responses of "often" or "sometimes" on questions Q1 and Q2, and "yes" on Q3, Q5, and Q6 are coded as affirmative (yes). Responses of "almost every month" and "some months but not every month" on Q4 are coded as affirmative (yes). The sum of affirmative responses to the six questions in the module is the household's raw score on the scale. Food security status is assigned as follows: Raw score 0-1-High or marginal food security (raw score 1 may be considered marginal food security, but a large proportion of households that would be measured as having marginal food security using the household or adult scale will have raw score zero on the six-item scale); Raw score 2-4-Low food security. Raw score 5-6-Very low food security. Percentage of participants with low or very low food security scores were reported.

The Modified Perceived Involvement in Care Scale (M-PICS) measures patients' perceptions of doctor-patient communication during the medical encounter. PICs includes 4 domains including 1-Health care provider information 2- Patient information 3- Patient decision making 4- Health care provider facilitation. The total score combines these 4 domains with a range from 20 poor-100 high reported at 12-month follow-up.

Nine items from the Cooking Matters Food Resource Management survey that assess 2 subscales (each scored on 1-5 item Likert scale)- Food Resource Management Practices (indicating the frequency with which respondents engaged in behaviors to maximize food resources) and Food Resource Management Confidence (extent to which participants showed self-confidence in shopping, preparing foods, and managing food resources on a budget). Higher scores indicate more frequent practices and greater confidence, respectively. There is not a summary score. The scoring for each subscale uses the average of items within that subscale.

Differences in raw BMI will be evaluated amongst study arms.

Differences in BMI50 will be evaluated amongst study arms. We reported using mean number of BMI units from the population mean which is defined as the distance from the BMI for age and sex at the 50th %tile.

Evaluate the percentage of children overweight and obese at 1-year follow-up per CDC guidance and definitions.
