At the time of enrollment, parents provided written consent for both themselves and their children, while children provided written assent. Both the consent and assent forms described the two available programs (healthy weight management program vs. social-emotional learning program) but did not indicate which program served as the intervention or control condition. Parents were informed of which program their children would participate in one month prior to the first session, but the study condition was not disclosed to them; however, the interventionists were aware of the program each group received. All study procedures and materials were approved by the University of Minnesota Institutional Review Board. The design and implementation of the intervention were informed by previous research and guided by a social-ecological framework. The healthy weight management intervention focused on weight-related behaviors and lifestyle practices intended to prevent excessive weight gain while minimizing potential harm. Three licensed school nurses, responsible for leading the intervention sessions, were aware that they are required to attend three mandatory one-hour training sessions before facilitating their first session. Intervention fidelity was assessed using a standardized procedure conducted by a staff member who did not deliver the intervention. Each group session was rated on a 0–10 scale, with 10 indicating full adherence to the intervention protocol. The average adherence score across all sessions and interventionists was 9.8 (SD = 0.1). Primary analyses followed an intention-to-treat approach and were conducted using a general linear mixed-effects model, adjusting for baseline body mass index z-score, age, sex, and pubertal status.
Review the detаiled descriptiоn оf the study prоvided below. Which of the following best describes the risk of biаs in this study? Select the one correct one аnswer. The primary outcome of the study was the child’s body mass index (BMI) z-score, calculated using measured height and weight at post-intervention, as pre-specified in the study protocol registered on ClinicalTrials.gov before participant recruitment. The BMI z-score precisely reflects how much a measurement deviates from the mean and is a useful tool for tracking weight changes. A z-score of 0 represents the average BMI for a given age and sex, while a positive z-score indicates a BMI higher than the average for that age and sex group, suggesting potential overweight or obesity. For data collection, parents and children in both the intervention and control groups were invited to participate at baseline and post-intervention. During each data collection session, parents completed an online survey on a study-provided iPad, reporting their child’s nutrition and physical activity behaviors. After the survey, two trained research staff members—who were not involved in delivering the intervention—measured children's height and weight using standardized protocols. Children wore light clothing provided by the study and no shoes during measurements. The trained research staff were not blinded to group assignments. There were no significant differences in measured height or weight between the two measurement staff members.
