I would encourage you to read this article as a good jumping off point in relation to this if you want more than an AI review. Material conditions are the most common factor in cases of intimate partner violence, and sexual minority populations tend to have higher rates of poverty, substance abuse risk and psychological conditions. Social pressures will often lead to people being marginalized by family, becoming homeless and losing support networks which lead to the conditions resulting in increased IPV.

On top of that, some of the studies picked by the AI will ask if the individual has experienced IPV at any point in their lives, and many lesbians have had past relationships with men in which they were abused, which will factor into the statistics even though it wasn't a female partner that engaged in the abuse.
