- The study shows polygamous families are healthier and happy than monogamous families
- According to the study, first wives, who tend to live with their husbands, had significantly better nutrition
- The children of second wives were found to be as healthy as those from monogamous families
A new study has shown polygamous families thrive better than monogamous ones in poor communities.
As a result of the study, researchers are now calling for greater cultural sensitivity among campaigners seeking to ban polygamy.
The research carried out in households from Tanzania showed polygamous families owned more cattle and farmed more land than monogamous ones in the same villages.
The study was published in the Proceedings of the National Academy of Sciences journal.
It also showed there was no evidence of children whose fathers had more than one wife were less healthy or hungrier than those in monogamous households.
Lead researcher, David Lawson, of the London School of Hygiene and Tropical Medicine said: “Children in polygamous households either do better or just as well as children in monogamous households within the same village.”
According to the study, first wives, who tend to live with their husbands, had significantly better nutrition and less stunting among their children than monogamous families.
The children of second wives, who usually live in separate homes adjacent to the first wife, were as healthy as monogamous families, although their food security was slightly lower.
Lawson said: “It’s an important finding because we have this very strong language used by the United Nations and others that polygamy is universally harmful. Most of the policy speak on this topic is not actually very evidence based. . . . What we are arguing for is cultural sensitivity.”
One in four married women in rural Tanzania have at least one co-wife, that is according to government data shows.
In Kenya, Maasai women often enter polygamous marriages with wealthier men in the community, unlike the Meru, and tend to be better educated and monogamous.
Lawson said: “Polygyny can be potentially protective within cultural settings where women lack direct control over resources."
