Interestingly, one study has found that the reasons for abstaining actually determine whether or not it results in slightly worse health outcomes than light drinking:

"Mortality risk is low for light drinkers and many individua ls who abstain from drinking—including those who abstain for religious and moral reasons, have a responsibility to family, were brought up not to drink, and are not social; it is higher among former, infrequent, and moderate drinkers, and individuals who abstain because they do not like the taste of alcohol, are concerned that they will lose control, or are concerned about adverse consequences. Unsurprisingly, mortality risk is by far the highest for heavy drinkers. We reveal that reasons for abstention capture heterogeneity in the risk of death among lifetime abstainers. "
