INTRODUCTION: Several studies have documented children gain more weight during the summer season. Despite high obesity rates, little research has included American Indian/Alaskan Native children and few studies have been longitudinal. This observational study examines seasonal weight variability over 3.5 years among ethnically diverse children including 2,184 American Indian/Alaskan Native children. METHODS: Children’s height and weight were measured before and after the summer 2012–2015 and analyzed in 2019–2020, including children with ≥2 consecutive measurements (N=7,890, mean age=8.4 [SD=2.8] years). Mixed effects models tested whether percentage of the 95th BMI percentile and BMI differed by season (summer versus rest of year) and ethnicity. RESULTS: American Indian/Alaskan Native (23.7%), Hispanic (19.8%), and Black (17.8%) children had significantly higher baseline obesity rates than White children (7.1%). The percentage of the 95th BMI percentile significantly increased during the summer compared with the rest of the year, with the strongest effects for children who were obese (b=2.69, 95% CI=1.35 to 4.03, p
