Spousal Concordance for Objectively Measured Sedentary Behavior and Physical Activity Among Middle-Aged and Older Couples.

This study revealed that sedentary behaviors were correlated with each other among couples and attachment to one's spouse did not moderate these correlations. Sedentary behaviors of 1 spouse might influence the other, regardless of attachment to one's spouse. The concordance for physical activity was weaker than that for sedentary behavior.
