Researchers at the Norwegian Institute of Public Health looked at data from nearly 20,000 married couples, looking at the risk factors associated with divorce over a 15 year period.
They found that essentially the more people drink, the higher the risk of divorce.
They also found that if spouses drink approximately the same amount there was a lower risk.
Interestingly, the report found that heavy drinking among women was more strongly associated with divorce than heavy drinking among men.
The risk was roughly tripled when a woman in a marriage drinks more heavily than her husband.
The researchers say that there can be many reasons for this such as it is more socially acceptable for heavy drinking amongst men and heavy drinking can often affect women more than men.
The study suggests that couple intending to marriage should harmonise their drinking patterns to reduce the risk of divorce.
Nicola Whitley, expert divorce solicitor at Swain & Co, comments, “In many cases we deal with, alcohol is often a common factor leading to separation. We see it feature especially in domestic abuse matters. You don’t have to put up with negative behaviour fuelled by alcohol. It is not excusable.”
