A study of 21,103 kids has found those with gay and lesbian parents fare just as well as those with heterosexual parents.

The questionnaire-based study measured kids with different parental arrangements in terms of their emotional and mental health difficulties.

Children of bisexual parents appeared to have greater difficulties, but this difference disappeared after taking into account markers of greater minority stress among bisexual parents.

“As lesbian, gay, and bisexual parented families become more visible, the findings bolster previous studies revealing that children raised in these families have comparable psychological well-being compared with children raised by heterosexual parents,” said lead author Dr. Jerel Calzo, of the San Diego State University Graduate School of Public Health.

“In addition, the results indicate the need for continued investment in strategies to prevent sexual orientation–based discrimination and to support sexual minority parents who may experience minority stress.”
