飲酒習慣が似ているカップルは長生きするかもしれない(Couples with similar drinking habits may live longer)

ミシガン大学の研究者による最新の研究では、夫婦が一緒に飲酒すると、一緒に長生きする傾向があることが分かりました。アルコールの使用パターンが似ているカップルは、長い結婚生活を送る可能性が高いとされています。しかし、これは健康のために飲酒を奨励するものではなく、単に夫婦のライフスタイルや関係満足度の一致を反映している可能性があるとされています。

Abstract

Background and Objectives
Spouses with concordant (i.e., similar) drinking behaviors often report better quality marriages and are married longer compared with those who report discordant drinking behaviors. Less is known regarding whether concordant or discordant patterns have implications for health, as couples grow older. The present study examined whether drinking patterns among older couples are associated with mortality over time.

Research Design and Methods
The Health and Retirement Study (HRS) is a nationally representative sample of individuals and their partners (married/cohabiting) over age 50 in the United States, in which participants completed surveys every 2 years. Participants included 4,656 married/cohabiting different-sex couples (9,312 individuals) who completed at least 3 waves of the HRS from 1996 to 2016. Participants reported whether they drank alcohol at all in the last 3 months, and if so, the average amount they drank per week. Mortality data were from 2016.

Results
Analyses revealed concordant drinking spouses (both indicated they drank in the last 3 months) survived longer than discordant drinking spouses (1 partner drinks and the other does not) and concordant nondrinking spouses. Analysis of average drinks per week showed a quadratic association with mortality such that light drinking predicted better survival rates among individuals and their partners compared with abstaining and heavy drinking. Further, similar levels of drinking in terms of the amount of drinking were associated with greater survival, particularly among wives.

Discussion and Implications
This study moves the field forward by showing that survival varies as a function of one’s own and one’s partner’s drinking.
