Objectively measured physical activity levels and sedentary time in children and adolescents with sickle cell anemia

Background. Regular physical activity in childhood and adolescent plays an important role in reducing the risk of cardiovascular health diseases, diabetes, and obesity in adulthood. However, little is known about physical activity levels (PA) and sedentary time among children and adolescents in Morocco. Objective. To examine gender, type of day, and age grade differences in objectively measured sedentary time, physical activity levels, and physical activity guideline attainment among children and adolescents in Morocco. Method. 172 children/adolescents (mean age = 10.92 ± 1.55 years, 49.4% are boys) were recruited for this study and wore a tri-axial accelerometer (GT3X+) for 7 consecutive days. Time spent in sedentary, PA levels, and daily steps were measured and compared according to gender, age grade, and the type of day (weekdays/weekends). Results. In weekdays children/adolescents spent more time in sedentary than weekends (p < 0.001). Boys were eight times more likely to meet the recommendation for at least 60 min of moderate to vigorous physical activity per day than girls (OR: 8.569; 95% [CI]: 4.23–17.32), p < 0.001. Conclusion. These findings highlight the need for effective and sustainable strategies and programs aiming to promote physical activity and to reduce sedentary behavior among children and adolescents in Morocco.

Joint Associations

Background: Peripheral artery disease (PAD) reduces physical activity, and both PAD and lower physical activity levels have been shown to increase mortality risk. Yet, their joint contributions to mortality have not been systematically studied, especially with the objective measure of physical activity. Hypothesis: PAD and lower 1-week objectively-measured physical activity are synergistically associated with mortality. Methods: We studied 7124 Hispanic adults aged 45-74 years at baseline from the Study of Latinos who adhered to an objective measure of physical activity using wearable accelerometers. We quantified the associations of the status of PAD (ankle-brachial index [ABI] ≤0.90 [PAD], 0.91-1.39 [no PAD], and ≥1.40 [possible PAD with ankle artery calcification]) and two physical activity measures (sedentary time [tertiles] and daily physical movement counts [tertiles]) at baseline with mortality using multivariable Cox models accounting for sampling weights. Results: During a median follow-up of 7.0 years, 289 participants died. Sedentary time and daily physical movement counts were weakly correlated (r=-0.17). Both low and high ABI, longer sedentary time, and lower physical movement counts were all independently associated with increased mortality risk (marginal cells in Table ). In terms of the joint associations of PAD and physical activity with mortality, they generally demonstrated synergistic associations (e.g., hazard ratio 4.43 [95%CI, 2.44-8.03] in ABI ≤0.9 plus top tertile of sedentary time and 5.46 [2.47-12.08] in ABI ≥1.40 plus top tertile of sedentary time vs. normal ABI with shortest sedentary time) (cross-categories in Table ), with no significant interactions. Conclusions: Both low and high ABI, and lower objectively-measured physical activity levels were significantly associated with greater risk of mortality independently of each other and potential confounders. Our results suggest the importance of objectively evaluating daily physical activity levels and leg vascular condition.

Objectively Measured Physical Activity

AbstractPhysical activity tends to be lower in school-age children with congenital heart disease than in healthy controls. To the best of our knowledge, objectively measured physical activity levels of preschool-age children with congenital heart disease have not been studied. Methods: A total of 10 children with either coarctation of the aorta (n=6; age 3.8±0.9) or tetralogy of Fallot (n=4, age 4.3±0.9) were recruited from the cardiology unit of McMaster Children’s Hospital. Height (103.7±8.2 cm) and weight (17.3±2.7 kg) measurements were recorded, and physical activity was determined using accelerometry over 7 consecutive days. Patients were compared with age-, sex-, and season of data acquisition-matched controls. Parents completed a questionnaire regarding the child’s physical activity and sedentary behaviours. Results: Patients spent on average 219.4±39.9 minutes engaged in total physical activity per day at the following intensities: light, 147.5±22.3; moderate, 44.0±11.8; moderate-to-vigorous, 71.9±22.6; and vigorous, 27.9±11.7. No significant differences were observed between patients and controls for total physical activity (p=0.80) or any of the intensities (p=0.71, 0.46, 0.43, and 0.45, respectively). Only 40% of patients and controls met the new Canadian Physical Activity Guidelines for the Early Years of at least 180 minutes of physical activity at any intensity every day. Of the patients’ parents, 90% believed that their child was as active, if not more active, than his/her siblings, and 80% of parents reported their child spending 1–3 hours in screen time activities daily. Conclusion: Children aged 3–5 years old with congenital heart disease have comparable physical activity levels to age-, sex-, and season-matched controls, and many do not meet Canadian Physical Activity Guidelines.
