Children raised by same-sex couples have better health and well-being in comparison to their peers, according to a groundbreaking new study which is being billed as the largest of its kind.

Conducted by Australia's University of Melbourne, the new research aimed to "describe the physical, mental and social well-being" of children with gay and lesbian parents, and "the impact that stigma has on them." On average, children raised by same-sex couples scored six percent higher than the general population when it came to general health and family cohesion.

Meanwhile, in other categories -- such as behavior, mental health and self-esteem -- those children reportedly scored the same as those raised by heterosexual parents.

"It appears that same-sex parent families get along well and this has a positive impact on health," Dr. Simon Crouch from the Jack Brockhoff Child Health and Wellbeing Program, Centre for Health Equity at the University of Melbourne, told CNBC of the results.

Crouch believes that an emphasis on skills, as opposed to traditional gender roles, accounted for the survey's results.

"So what this means is that people take on roles that are suited to their skill sets rather than falling into those gender stereotypes," he is quoted as saying. "What this leads to is a more harmonious family unit and therefore feeding on to better health and wellbeing."

The study comprised input from 500 children and 315 parents who are in same-sex relationships, and seemed mostly in line with previous research. Earlier this year, a Williams Institute report found that children of lesbians reported having higher self-esteem and lower conduct problems than those of heterosexual couples.
