Fewer than 3 % of 15-year-olds do.

Study participants were kids involved in agency analysis on youth development, recruited from 10 hospitals around the national country. Family income, race and ethnic background matched the U.S. Population. The researchers tracked the children’s activity levels starting at age 9, using an accelerometer – a device about how big is a small belt buckle that attached to a belt around the waist and recorded movement. Activity levels were counted at ages 9, 11, 12 and 15 through the college week and on weekends.Data for individuals were censored at the start of the uncontrolled period in each research. Lipid measurements were summarized by using medians or means, and treatment distinctions were tested by using the Wilcoxon rank-sum check without adjustment for multiplicity. Safety was described based on the incidence of adverse events. The minimum LDL cholesterol category for a patient was determined by the minimum value seen in the randomized, controlled amount of the studies. We utilized the log-rank test to analyze the difference in cumulative incidence curves for cardiovascular occasions. Hazard ratios were approximated by using Cox proportional-hazard models without stratification. Statistical analyses were performed by using SAS software, version 9.3, and R software, version 3.0.3.
