a. Adjusted for body mass index, age, perceived stress score and partner enrolled in the study.
b. Perceived Stress Scale used was measured by the Perceived Stress Scale 10 by MacArthur Research Network. A stress score of ≤20 was considered as low stress while a stress score of >20 was considered as high stress.
