Canadian study: Interrupting a child’s sedentary time has benefits

1 Dec

Moi wrote in Seattle Research Institute study about outside play: Play is important for children and outside play is particularly important. Kids Discover Nature has some excellent resources about outside play. In the post, 10 Reasons Why Kids Should Play Outside reasons for outside play are given.

A study by Seattle Research Institute reinforces these findings.

Brian Toporek reported in the Education Week article, Regular Breaks From Sedentary Time Found to Improve Children’s Health:

The simple act of regularly interrupting sedentary time by standing up, on the other hand, could have beneficial effects for children, according to a study published last week in the open-access online journal PLOS ONE.
Researchers analyzed data from 522 children from Quebec, Canada, between the ages of 8 and 11 (286 boys and 236 girls), all of whom had at least one biological parent with a body mass index of 30 or greater. Each child used an accelerometer for seven days to track when he or she was engaging in light or moderate-to-vigorous physical activity and when he or she was sedentary. The children self-reported how much time they spent watching television and playing video games or using a computer.
Based on the data collected, the researchers calculated a “cardiometabolic risk score,” or a measure of risk for diabetes and heart disease, for each child. They used that score to determine which activities reduced the risk of cardiometabolic-related health problems.
The researchers discovered that children who frequently take breaks from sedentary time—even through the simple act of standing up every five minutes or so—could have lower levels of cardiometabolic risk than children who endure longer bouts of inactivity. ….http://blogs.edweek.org/edweek/schooled_in_sports/2013/11/regular_breaks_from_sedentary_time_found_to_improve_childrens_health.html

Abstract
Background
Although reports in adults suggest that breaks in sedentary time are associated with reduced cardiometabolic risk, these findings have yet to be replicated in children.
Purpose
To investigate whether objectively measured sedentary behavior, sedentary bouts or breaks in sedentary time are independently associated with cardiometabolic risk in a cohort of Canadian children aged 8–11 years with a family history of obesity.
Methods
Data from 286 boys and 236 girls living in Quebec, Canada, with at least one biological parent with obesity (QUALITY cohort) were collected from 2005–2008, and analyzed in 2013. Sedentary behavior, light and moderate-to-vigorous physical activity were measured over 7 days using accelerometry. Leisure time computer/video game use and TV viewing over the past 7 days were self-reported. Outcomes included waist circumference, body mass index Z-score, fasting insulin, fasting glucose, triglycerides, HDL-cholesterol, C-reactive protein and a continuous cardiometabolic risk score.
Results
After adjustment for confounders, breaks in sedentary time and the number of sedentary bouts lasting 1–4 minutes were associated with reduced cardiometabolic risk score and lower BMI Z-score in both sexes (all p<0.05). The number of sedentary bouts lasting 5–9 minutes was negatively associated with waist circumference in girls only, while the number of bouts lasting 10–14 minutes was positively associated with fasting glucose in girls, and with BMI Z-score in boys (all p<0.05). Leisure time computer/video game use was associated with increased cardiometabolic risk score and waist circumference in boys, while TV viewing was associated with increased cardiometabolic risk, waist circumference, and BMI Z-score in girls (all p<0.05).
Conclusions
These results suggest that frequent interruptions in sedentary time are associated with a favourable cardiometabolic risk profile and highlight the deleterious relationship between screen time and cardiometabolic risk among children with a family history of obesity.
