The new study is just the latest that has found an association between marriage and health.

  • A 2018 study found that frequent marital conflict worsens health for both women and men, but especially for men.

  • A 2019 study found that, surprisingly, unhappily married men have a lower risk of developing diabetes and a better response to treatment if they do develop it. The study's lead author hypothesizes that a wife's nagging might drive men to seek better medical care.
