Trial Outcomes & Findings for Effectiveness of Differing Levels of Support for Family Mealtimes on Obesity Prevention Among Head Start Preschools (NCT NCT02487251)

NCT ID: NCT02487251

Last Updated: 2022-01-11

Results Overview

Research staff measured children without shoes or heavy clothing. Measures were taken twice and averaged. BMI was calculated and child BMIz derived. Child obesity was defined as BMI \> 95th percentile and overweight/obesity defined as a BMI \> 85th percentile for age and sex. Note that due to the COVID-19 pandemic, data on BMIz were not collected beginning in March 2020. The z-score is based on United States Centers for Disease Control growth references for children. A z-score of 0 reflects the 50th percentile based on the US CDC children's reference growth charts. A z-score \< -1.645 indicates that the child is underweight. A healthy BMIz score is between -1.645 and 1.036. BMIz \>1.036 = criteria for overweight; BMIz \>1.645 = criteria for obese

Timeframe: Prior to the implementation of the intervention (Baseline) and immediately post the 12 week intervention period (Post).

Population: Parents of preschool aged children; note that observed dietary quality data was only collected in Phase 2.

Report of the child's usual eating habits (fruit) using the Pennington Remote Food Photography method. When using the RFPM and SmartIntake app, parents place a reference card next to the child's food and capture images of the food selection and plate waste. The parent identifies foods that are not easily identified by wrappers or containers by typing a food description into a text box. These data and food images are automatically sent by the app to the server-based Food Photography Application©, which is used to manage the data collection process and analyze the food images to estimate energy and nutrient intake. First, the foods in the images were linked to a match from the United States Department of Agriculture's Food and Nutrient Database for Dietary Studies (FNDDS; USDA, 2018). Second, a standard portion image, which contains an image of the same or a similar food that was carefully weighed to represent various portion sizes, was identified from an archived food image database.

Report of the child's usual eating habits using the Block Kids 2004 Food Frequency. Parents self-reported their children's dietary intake using the Block Dietary Data Systems Kids Food Screener-Last Week (BKFS, Version 2), a 41-item survey assessing nutrients and food groups in children aged 2-17 years (Hunsberger et al., 2015). Nutrients and food groups are reported from multiple items summed from each survey construct. The current study operationalized dietary quality in cup equivalent as reflecting the following food groupings as indicators of higher quality dietary patterns (Haya et al., 2013): fruit/fruit juice
