This has been "known" for a long time, but here's confirmation. And it makes perfect sense. People from MENA countries (which aren't the only ones this is about, but they seem overrepresented within the larger overrepresented group) have been brought up in cultures with often horrific views on women and gender equality, decades or even centuries behind the generally progressive views of Sweden. This is NOT a controversial thing to say (or it shouldn't be), and it's not a racist or xenophobic thing to say. It's not a "brown people are bad" thing, it's a "certain cultures are stuck in the past" thing.
Now, what do we do about it? I don't know, there's no simple answer, obviously. But I guess it's about teaching immigrants Swedish values, and making sure they understand they are expected to abide by them. That starts with learning Swedish, which should be mandatory. Then learning about Swedish culture, values, etc. That doesn't mean "leave everything about your own culture behind", the good parts you're welcome to keep. But we can't accept viewing women as the property of men, honor culture, etc.
Also integration in general has to start working. It has generally failed spectacularly in Sweden, with massive segregation resulting in insular communities of like-minded people who don't mix much with society in general. Partly because of failed politics, partly because they don't want to. Well, I think they'll have to.
