Body size may influence women's lifespan more than men's
Budget 2019 : A new study has claimed that body size -- height and weight -- of women influence their lifespan far more that it does that of men.
The study was published online in the Journal of Epidemiology & Community Health.
The findings indicate that while physical activity is linked to longevity in both sexes, the more time men spend being physically active add to their chances of reaching old age, while 60 minutes a day was associated with the best chance for women for longevity.
The study also finds that while average life expectancy has risen over the past few decades, it has recently started to plateau in some developed nations, with increasing levels of obesity and physical inactivity thought to be behind the trend.
While previous research has looked at the associations between weight (BMI), physical activity, and reaching old age, most combined both sexes or focused only on men. However, women and men's lifespan differ, which may be influenced by factors like hormones, genes and or lifestyle.
To explore these differences further, the researchers analysed data from the Netherlands Cohort Study (NLCS), which included more than 1,20,000 men and women aged between 55 and 69 when it began in 1986.
The researchers wanted to see if there were any links between height, weight, leisure time physical activity and the likelihood of reaching the age of 90. They also wanted to see if there were any differences between men and women.
