A study by Munich Re shows that physical activity, measured by wearable sensors, is a preacher of mortality reliable. The reinsurer has evaluated their effectiveness in stratifying the risk profile of mortality of a data set provided by Vivametrica, a company health analysis. The data were collected in the United States.
The wearable sensors measure the level of physical activity daily by the number of steps and minutes of physical activity (moderate to high). The report indicates that these measures segment effectively the mortality risk, taking among others into consideration the age, sex and tobacco use.
Several analysis techniques
Munich Re said that its actuaries have applied several analysis techniques to assess the value of this data source. The number of steps per day provides a segmentation of mortality even after considering several traditional factors taken into account at the time of subscription such as smoking, blood pressure, body mass index and other health indicators.

«We see many opportunities to use this information in assessing risks to the life and disability insurance. The activity data captured by the portable devices and smart phones are becoming more and more present. It becomes easier to incorporate this source emerging evidence in the warrant to extend the insurability, » says Mike Tath, first vice-president, research, analytics and underwriting at Munich Re.
