The aim of this study was to compare the health-related quality of life of fathers under different infant feeding type scenarios. The Medical Outcomes Study 36-item Short-Form was used to measure the health-related quality of life of 1,699 fathers, and the scores were used to look for associations with different infant feeding methods. Multivariable linear regression analysis was used to explore the contribution of the other potential related factors on fathers' quality of life. After controlling for confounding factors, fathers whose infants were ever being breast-fed reported lower scores than fathers whose infants were bottle-fed. Except for the infant feeding pattern, having a job, higher family income, and being the major caregiver were positively related to the father's quality of life. Fathers may not benefit during breast-feeding process. Because fathers' involvement plays an important role in the success of breast-feeding, the development of interventions that enable fathers to support their breast-feeding partner is very important.
