Many parents
struggle with keeping their teens active amid the constant lure of computers,
phones, video games and technology. Less than 25 percent of adolescents aged 12
to 15 are reaching the World Health Organization's guidelines for physical
activity. For this age group, the guideline is 60 minutes of moderate activity
per day. Researchers in Iowa were interested in determining the impact families and friends of teens have on their physical activity levels.
The results of
this recent longitudinal study, which included over 300 teens in the
mid-western U.S., were published in the International
Journal of Behavioral Nutrition and Physical Activity and included data
collected over a five-year span. Accelerometer recordings of Moderate and
Vigorous Physical Activity (MVPA) and psychosocial surveys of family and friend
support of physical activity were documented when the teens were 13, 15 and 17
years of age.
This is one of the first studies to track adolescent psychosocial support combined with
recorded physical activity. While both family and friend support was predictive
of higher rates of MVPA within this five-year span, the effect decreased as
they matured. Additionally, family and friend physical activity support
measures when participants were 13 years of age were significantly predictive
of support recorded at 17 years of age.
Bottom Line: Encouraging
physical activity at a young age is important as it may become more difficult
to engage teens as they mature. Encourage them to be active in any way that
interests them. Organized sports are not the only way to get moving; try other
recreational activities such as hiking, gardening or swimming. Get involved as
a family and have kids bring a friend along too! Teach kids the value of enjoying
fun, active pursuits with friends and family; it will benefit them as they move
toward becoming independent, healthy adults!
