"Marriage may drive a woman to drink, not because she's unhappy but because she's influenced by her husband's alcohol consumption, new research suggests. And men, on average, drink more than women.

Men, on the other hand, spend less time with their drinking buddies and more with their wives after tying the knot. The result? Married men down fewer beers than their single counterparts."

"Men on average drink more than women, and this statistic plays out during marriage and divorce. Although men in the study still drank more than women during every life stage, the majority of men who were interviewed described three main reasons why marriage curbed their drinking: They spent less time with their drinking buddies; their wives drank less than they did; and their wives worked to limit how much they drank."

"Previous studies have consistently shown that married people drink less than single people, with the anti-drinking association stronger in married men than women. The new study confirmed this relationship in men, but it showed that married women actually drink more on average than women who were never married, divorced or widowed."

As far as I am aware, the IDIP/MOP program, when they do their outtake interview, do not use marital status as a factor to decide if someone is at high risk. They do use other stupid factors, however, such as if you smoke, you are more likely to be determined to be at high risk.
