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.

An Arctic University of Norway study reported about the risk of osteoporosis for boys who spend too much time in front of computer screens.

The International Osteoporosis Foundation reported about the Arctic University of Norway’s study regarding boys and screen time.

DOES TOO MUCH TIME AT THE COMPUTER LEAD TO LOWER BONE MINERAL DENSITY IN ADOLESCENTS?
April 4, 2014
Study of Norwegian students finds great variation in impact on bone mineral density in boys and girls, concluding that teenage boys that spend more time in front of screen have weaker bones.
Results of a study presented today at the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases, showed that in boys, higher screen time was adversely associated to bone mineral density (BMD) at all sites even when adjusted for specific lifestyle factors.
The skeleton grows continually from birth to the end of the teenage years, reaching peak bone mass – maximum strength and size – in early adulthood. Along with nutritional factors, physical activity can also greatly impact on this process. There is consequently growing concern regarding the possible adverse effects of sedentary lifestyles in youth on bone health and on obesity.
The skeleton grows continually from birth to the end of the teenage years, reaching peak bone mass – maximum strength and size– in early adulthood. Along with nutritional factors, physical activity can also greatly impact on this process. There is consequently growing concern regarding the possible adverse effects of sedentary lifestyles in youth on bone health and on obesity.
The Norwegian study explored the hypothesis that greater computer use at weekends is associated with lower BMD. The data was obtained from 463 girls and 484 boys aged 15–18 years in the Tromsø region of Norway. The students participated in the Fit Futures study from 2010–2011 which assessed more than 90% of all first year high school students in the region.
BMD at total hip, femoral neck and total body was measured by DXA (dual-energy X-ray absorptiometry). Lifestyle variables were collected by self-administered questionnaires and interviews, including questions on time per day during weekends spent in front of the television or computer, and time spent on leisure time physical activities. The associations between BMD and screen time were analyzed in a multiple regression model that included adjustment for age, sexual maturation, BMI, leisure time physical activity, smoking, alcohol, cod liver oil and carbonated drink consumption.
Not surprisingly, the researchers found that boys spent more time in front of the computer than girls. As well as high screen time being adversely associated to BMD, in boys screen time was also positively related to higher body mass index (BMI) levels. In contrast to the boys, girls who spent 4–6 hours in front of the computer, had higher BMD than counterparts who spend less than 1.5 hours screen time each day – and this could not be explained by adjustments for the different parameters measured.
Lead author of the study Dr Anne Winther, Arctic University of Norway, Tromsø, stated, “Bone mineral density is a strong predictor of future fracture risk.O ur findings for girls are intriguing and definitely merit further exploration in other studies and population groups. The findings for boys on the other hand clearly show that sedentary lifestyle during adolescence can impact on BMD and thus compromise the acquisition of peak bone mass. This can have a negative impact in terms of osteoporosis and fracture risk later in life.”
According to the International Osteoporosis Foundation (IOF), approximately one in five men over the age of fifty worldwide will suffer a fracture as a result of osteoporosis. Very low levels of awareness about osteoporosis risk and bone health in males has prompted IOF to focus on osteoporosis in men as a key World Osteoporosis Day theme in 2014.

Osteoporosis is the most common bone disease. It can be prevented with a healthy diet and staying physically active. Learn about factors that can make bones stronger or weaker.
What Causes Compression Fractures?
Most spinal compression fractures are never diagnosed because many patients and families think the back pain is merely a sign of aging and arthritis. These weakened bones cause the spine to collapse. Read more.

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.
