Study summary

The investigators propose a study to evaluate the success of a bicycle distribution program in increasing physical activity level, decreasing sedentary activity levels and positively affecting body-mass index (BMI) in participants aged 6 to 12 years old with overweight or obesity, who do not already own a bicycle, and are patients at the Children's Hospital Colorado Child Health Clinic (CHC), Lifestyle Medicine Clinic, or Rocky Mountain Youth Clinics. The investigators anticipate that the receipt of a bicycle will increase physical activity level, decrease sedentary activity time and decrease or stabilize patients' BMI. The investigators will answer this research question by distributing bicycles to 525 children and conducting follow up visits over the course of a year to measure the outcomes of interest.
