Numerous studies have found that married people have better health than the unmarried. These studies relied on self reported health outcomes and considered only current marital status or transitions over relatively short periods. We employed data from a population based birth cohort to summarise longitudinal patterns of partnership status spanning 21 years. After controlling for selection due to early life and early adulthood characteristics, we found that lifecourse trajectories of partnership status were associated with haemostatic and inflammatory markers, the prevalence of metabolic syndrome and respiratory function in mid-life. Never marrying and neither cohabiting was detrimental to health in mid-life for both genders but the effect was more pronounced in men. Women married during their late 20’s or early 30’s that remained married had the most optimal health in mid-life. Not married cohabiters of both genders had similar mid-life health outcomes with those that were married.
