BMI. Obesity was measured with a BMI category variable. The variable was categorical, with 4 levels, Underweight, Normal, Overweight, and Obese. Underweight children were in the 5th percentile for BMI. Normal BMI and was somewhere between the 5th and 84th percentile for their BMI. Overweight children were between the 85th to 94th percentile for BMI. Children with a BMI at or above the 95th percentile were coded as Obese. BMI was calculated for children between the ages of ten to seventeen, and used parent reported height and weight data to calculate it. BMI was then classified into the above categories using CDC BMI-for-Age Growth Charts. There were three variables related to sleep. One was whether or not children get the recommended amount of sleep. The data were coded into two categories- the child sleeps the recommended number of hours, or the child sleeps less than the recommended number of hours. This variable was not included in the models, as hours of sleep provides more information and it can be determined whether or not a child is sleeping a sufficient amount from that variable. Whether or not the child has a consistent bedtime was a second sleep-related variable. Parents were asked how often their child goes to bed at the about the same time on weeknights. The responses are coded as follows: the child always goes to bed at about the same time on weeknights, the child usually goes to bed at about the same time on weeknights, the child sometimes goes to bed about the same time on weeknights, and the child rarely or never goes to bed about the same time on weeknights. Hours of sleep was the third sleep variable. The data came coded as a categorical variable with seven levels including: less than 6 hours, 6 hours, 7 hours, 8 hours, 9 hours, 10 hours, and 11 or more hours. It was re-coded to be a linear variable. Less than 6 hours of sleep and 6 hours of sleep were coded as 6. 7, 8, 9, and 10 -hours were re-coded as their respective integers. 11 or more hours was re-coded as 11 hours. The variable was made linear using the as.numeric command in R. Physical activity was categorized into 4 levels, for the number of days children were physically active for at least 60 minutes a day. The levels are: 0 days a week for 60 minutes, 1 to 3 days a week, 4 to 6 days a week, and every day. Television watching was coded as a categorical variable as well, with 5 categories; the child does not watch television, the child watches less than an hour of television a day, th...
