Previous studies have demonstrated that high alcohol consumption is a predictor of divorce. However, there is a lack of studies with prospective data from both spouses. The effects of drinking among husbands versus wives and of concordant versus discordant drinking in couples are therefore unknown. Concordant drinking may lead to increased divorce rates because the malignant effects of heavy drinking are experienced in double doses; alternatively it may lead to marital stability due to partner compatibility.
All inhabitants in a Norwegian county were invited to participate in a health study. We identified 19,977 married couples where both spouses participated. Respondents provided information on alcohol use and mental distress. Survival analysis was applied to study the risk of divorce over the next 15 years. Demographics and mental distress were used as covariates.
Heavy drinking among men (hazard ratio [HR] = 1.39) and women (HR = 1.41) increased the risk of future marital dissolution, even after adjusting for demography (reference group "light drinkers"). The HR for divorce was 1.51 when only the husband was a heavy drinker, while it was 3.07 when only the wife was a heavy drinker. Moreover, there were strong interaction effects: concordant abstainers (HR = 0.40) and concordant heavy drinkers (HR = 0.35) had lower risks of divorce compared to the risk expected from combining the main effects. Nevertheless, couples with 2 heavy drinkers (HR = 1.63) had higher risk of divorce than couples with 2 light drinkers.
This study demonstrated that both the level of alcohol use and compatibility in alcohol use are important predictors of marital dissolution.
先前的研究表明，大量饮酒是离婚的预测因素。然而，缺乏来自配偶双方的前瞻性数据研究。因此，尚不清楚丈夫饮酒与妻子饮酒、夫妻双方饮酒一致与不一致的影响。一致饮酒可能会导致离婚率上升，因为大量饮酒的恶性影响会加倍；或者，由于伴侣之间的兼容性，它可能会导致婚姻稳定。
邀请挪威一个县的所有居民参加一项健康研究。我们确定了 19977 对已婚夫妇，他们的配偶都参加了研究。受访者提供了关于饮酒和精神困扰的信息。生存分析用于研究未来 15 年内离婚的风险。将人口统计学和精神困扰作为协变量。
男性（危险比[HR] = 1.39）和女性（HR = 1.41）的重度饮酒增加了未来婚姻破裂的风险，即使在调整了人口统计学因素后（参考组为“轻度饮酒者”）。当只有丈夫是重度饮酒者时，离婚的 HR 为 1.51，而当只有妻子是重度饮酒者时，HR 为 3.07。此外，还存在强烈的交互作用效应：一致的戒酒者（HR = 0.40）和一致的重度饮酒者（HR = 0.35）与组合主要效应所预期的离婚风险相比，离婚风险较低。然而，与夫妻双方均为轻度饮酒者相比，夫妻双方均为重度饮酒者（HR = 1.63）离婚的风险更高。
这项研究表明，饮酒水平和饮酒一致性都是婚姻解体的重要预测因素。
