Obesity among women in Scotland leads them to deaths at an increased rate went unnoticed due to the emphasis on the side-effects of smoking and drinking. Recent research done by some researchers revealed that death rates of women in Scotland increased due to the disease of obesity since 2004.

The study revealed that women who did not smoke were likely to be over weight than the ones who smoked and that these over-weight women were at a higher risk of dying or contracting heart-borne diseases. The decline in the rates of smoking among women was believed to be a reason of increase in obesity among women.

A study conducted on 3613 Scottish women who did not smoke discovered that they were obese than the women who smoked. The research was published in the British Medical Journal that stated that high smoking rates 35 years ago had probably concealed the true extent of obesity in non-smoking women.

Women belonging to the low-income group were found to be contracting obesity at a higher rate than the one belonging to a higher income group. As per the researchers, "Women who had never smoked and were not obese had the lowest mortality rates, regardless of their social position".
