Adolescent obesity is a serious health problem in the United States that occurs when teens weigh more than a healthy weight for their height. Adolescent obesity may be caused by prolonged sedentary time. There may also be racial/ethnic differences in sedentary time among adolescents. School environment and community demographics based on school type may also be triggers for obesity in adolescents. The purpose of this study was to determine the relationship between sedentary time and body mass index (BMI) in adolescents and describe adolescent sedentary time by race/ethnicity and school type. The data used in this study were extracted from the California Health Interview Survey (CHIS)-Adolescent 2020, which was conducted between September 2019 and November 2020 by randomly selected households in California. A simple linear regression, a one-way ANOVA, and independent t-test were used to analyze the data. The findings showed that sedentary time during weekend among California adolescents has a limited impact on obesity. However, racial/ethnic differences were in sedentary time among adolescents, but school type was not a significant predictor of obesity.
