EDGERTON, Wis. (AP) – A school and hospital in southern Wisconsin are using wireless digital wrist devices to track some students’ health.        The Janesville Gazette reports (http://bit.ly/1ikMgL4 ) the Edgerton Hospital fitted 21 Edgerton Middle School students in late November with Fitbit Flex. It’s part of a 10-week pilot program to measure how active students are and to determine how their diet and sleep patterns factor into their overall health. Principal Phill Klamm organized the program when he learned some students were lukewarm about gym class.        According to preliminary data results, the students don’t drink anywhere near enough water. They also don’t eat enough fruit, and some aren’t getting enough sleep. Many students seem to get enough activity but many get headaches that seem to come on regularly about halfway through the day.
