According to American Journal Of Epidemology, when one spouse becomes obese, the other’s risk of obesity almost doubles. Married couples can be a big breaking point when trying to prevent obesity interventions.
“In the present study, we aimed to evaluate whether an individual’s risk of obesity is associated with spousal risk of obesity and whether an individual’s change in body mass index (BMI; weight in kilograms divided by height in meters squared) is associated with spousal BMI change. We analyzed data from 3,889 spouse pairs in the Atherosclerosis Risk in Communities Study cohort who were sampled at ages 45–65 years from 1986 to 1989 and followed for up to 25 years. Future research should consider exploring the efficacy of obesity prevention interventions in couples.”
