Overweight/Obesity
Height (cm) and weight (kg) were extracted from the most recent clinic visit and used to calculate body mass index (BMI) and BMI percentiles using age and gender Center for Disease Control growth charts(11). Underweight, overweight and obesity weight status category were the primary outcome and were defined as a BMI percentile of <5th, >85thand >95th percentile, respectively. BMI z-scores were also calculated based on age and gender norms (12).
Mississippi state and national weight status estimates for youth 10-17 years were obtained from the 2016-2017 National Survey of Children’s Health (NSCH) with a data agreement between the study authors and the Data Resource Center and the Child and Adolescent Health Measurement Initiative (CAHMI). The NSCH was a nationally representative survey, sent via mail and email to randomly selected addresses, on the health and well-being of youth aged 0 to 17 years living in the United States. This was both a population-based and cross-sectional study, which included 37,409 youth. Parent-reported height and weight data were utilized to calculate Body Mass Index (BMI). Weighted estimates were calculated for this study using the SPSS v26 Complex Samples module (IBM SPSS, 2019) (13).
