Background: CIRCUIT (CHU Sainte-Justine, Montreal, QC), is a lifestyle intervention focused on increasing physical activity among youth aged 5–18 y at risk of cardiovascular disease. Over a 2-y period, a personalized strategy emphasizing available resources in the home and school environment is delivered by a team comprising a kinesiologist, dietician and psychologist.
Objective: To assess change in key CVD health outcomes among 108 participants who completed the 2-y intervention.
Methods: Body mass index z-scores (zBMI), adiposity (Tanita), cardiorespiratory fitness (VO2max) and physical capacity (anaerobic fitness, number of push-ups, sit-ups, hand grip strength, leg power), blood pressure z-scores (zBP), fasting blood glucose and lipid profile (LDL, HDL, triglycerides) were collected at baseline, year 1 and year 2. Analyses consisted of paired t-tests (for age-sex standardized BMI and BP) or multivariable mixed effect models, adjusted for age and sex, for other outcomes.
Results: Compared to baseline, zBMI and diastolic BP measures improved at years 1 and 2: zBMI decreased by 0.20 SD and 0.29 SD, respectively (p<0.001); similarly, diastolic zBP decreased by 0.33 SD and 0.56 SD, respectively (all p<0.001). At year 1, participants improved %trunk fat (β=-1.31, p=0.033), VO2max (β=2.32, p<0.001), anaerobic fitness (β=0.73, p<0.001), and physical capacity (push-ups, sit-ups, hand grip, leg power). Further improvements (albeit attenuated) were noted at year 2 for most indicators, except %trunk fat and sit-ups. No change in systolic zBP, lipid profile or fasting blood glucose was observed.
Conclusion: The CIRCUIT intervention was associated with many favorable effects on anthropometrics, fitness, and physical capacity.
