Bangalore: Do you take sick leaves frequently? If yes, then you should definitely know that a British study, recently published by the researchers in the journal BMJ open, demonstrated that the better people performed on childhood intelligence tests, the less likely they were to end up on taking long-term sick leave as adults, reports, Dan Fastenbeg on Aol Jobs.

For the longitudinal study the cognitive abilities of 23,000 people were tested in the year1946, 1958 or 1970. Amid the groups of 1946, 47 percent which is nearly a half, who ended up on long-term sick leave as adults had been placed in the bottom quarter of childhood ability test. Whereas only 13 percent of those who ended up on leave were from the top quartile. For the later samples the splits were quite similar, however the difference between the quartiles weren't quite as striking.

Based on the testing for both verbal and nonverbal intelligence the cognitive abilities were ranked. However the findings of the study revealed that measure to be insufficient on its own in predicting the probability of ending up on disability or sick leave, or the dole, as it's identified in Britain. The major role was played by wealth and education in reducing the probability of landing on the dole. The study's author led by Max Henderson wrote "There was some attenuation of the effect when adult social class and, particularly, educational attainment was included, and this attenuation was greater for those of lower cognitive ability,". "This suggests that some of the effect of lower cognitive ability is mediated by educational attainment."

Furthermore, the research conducted in the U.S. observed the connection between good grades and good health. The Wisconsin Longitudinal study that was highlighted in a 2010 report of "The New York Times" tracked the 1957 graduates of the state's high schools. According to that study which followed 10,000 people, those individuals who had finished in the top quartile were, overall, half as probable to have experienced the health failures than their counterparts who graduated in the lowest quartile were experiencing.
