Indicator Report - Physical Activity, Adolescent: Watching 3+ Hours of TV Daily

Why Is This Important?

Recent studies conclude that the amount of time children spend watching television has a direct relationship to their weight. Children who viewed the most number of hours of television per day had the highest prevalence of obesity (this held true regardless of age, race/ethnicity and family income)(1). Children who were limited to one hour or less of TV per day were far less likely to be overweight. Children who watched more hours per day of TV and for longer periods of time were less likely to engage in physical activity. That lack of physical activity and the increase in unhealthy behaviors contribute to emerging health issues for our children, such as high cholesterol and high blood pressure, diabetes, gall bladder disease, and sleep apnea (2).

Quartile Map of Percentage of High School Students with Three or More Hours of Screen Time by County, New Mexico, 2011

A "Quartile" map assigns areas to four groups. Each group includes the SAME NUMBER of areas. Group membership and map color are based on the rank order of area rates, from the lowest rate to the highest. The bottom 25% (bottom quartile) of areas has the lowest rates, the next 25% has the second lowest rates, the next 25% has the second highest rates and the top 25% of areas has the highest rates. Areas with the darkest color have the highest rates. Percentile maps such as this assign areas to different groups regardless of how close the rates actually are. In other words, just because two areas are in different groups doesn't necessarily mean that their rates are significantly different.

Data Notes

Rates for Chaves County, Harding County, and Union County were supressed because of inadequate response rates from those counties. The NM rate was calculated from the standard CDC YRRS dataset and is consistent with the rates found on the CDC Website. The county rates were calculated from a special New Mexico dataset that has a larger survey sample size.
