A new study, published in The BMJ, reports that children with higher IQ are believed to have higher chances of longer life and lower risk of such diseases as heart disease, stroke, smoking-related cancers, respiratory disease, and dementia.
For the study, the researchers collected data from 33,526 and 32,229 women born in Scotland in 1936, who took validated childhood intelligence test at age of 11, and who could be followed to cause of death data up to December 2015.
Scientists say: “Importantly, it shows that childhood IQ is strongly associated with causes of death that are, to a great extent, dependent on already known risk factors. Tobacco smoking and its distribution along the socioeconomic spectrum could be of particular importance here.”
According to a new research, published in The BMJ, cycling or walking to work can lower the risk of death from all causes compared to the inactive ways of commuting. The scientists say that the greatest effect was noticed in cyclists.
For their study, the researchers used data from 264,377 participants with an average age of 53 from the UK Biobank (a database containing biological information from more than 500,000 U.K. adults).
Having analyzed the received information, the researchers conclude that “the findings, if causal, suggest population health may be improved by policies that increase active commuting, particularly cycling, such as the creation of cycle lanes, cycle hire, or purchase schemes, and better provision for cycles on public transport.”
The researchers discovered that identical twins in Denmark tend to lived longer compared to fraternal twins, and both types of twins usually outlived men and women in Denmark who were not twins. The results of the study were published in the journal PLOS ONE.
The scientists believe that the longevity boost in identical twins is a result of social bonds between two siblings.
The close relationships between twins act as a buffer for risky behaviours during their lives and can provide a source of emotional or financial support.
For the study, the team analyzed data from the Danish Twin Registry, which is one of the longest-running databases on twins in the world.

A recent study suggests that women who often attend religious services are at lower risk of death from various causes, including the risk of death from such diseases as heart disease and cancer.
However, the research doesn’t prove a cause-effect relationship between attending religious services and longer life, but researchers claim that the association appears to be strong.
A team of researchers pulled data from the national health study of female nurses to examine attendance at religious services and posterior death in women.
The data analysis showed that those women who attended religious services more than one time a week had a 33% lower risk of death compared to those who have never attended religious services. Also, the study results showed that attending religious services more than one time a week connected to a 27% lower risk of death from cardiovascular disease and a 21% lower risk of death from cancer.
“I think it’s not just one thing, but a combination of factors,” Tylor J. VanderWeele, study author, Ph.D., of the Harvard T.H. Chan School of Public, said. “Some of it is that if you attend services you develop a community and you, therefore, have social support, which is beneficial both psychologically and materially for health. Also, by attending services there are certain social norms that make things like smoking less likely, which is prospective for health.”
