Investigators are interested in the effect of TV watching on obesity rates among young children. They therefore conducted a cohort study in which they enrolled over 1 million children ages 0 - 23 months in 2008. At the baseline assessment, they asked parents to report the average number of hours of TV the children watched each day. They then followed up with the children 2-3 years later in 2010 to assess their BMI (and incidence of obesity). Investigators found an incidence rate of obesity of 14 cases per 100 person-years among children who watched 2 hours or more of TV per day and 8 cases per 100 person-years among children who watched less than 2 hours of TV per day. The overall incidence rate of obesity among this population in the U.S. is estimated to be 10 cases per 100 person-years. What is the excess risk of obesity attributable to watching TV for 2 hours or more per day among young children? Please report your answer per 100 person-years. Select one:
