Who knows? Maybe they are. I’m not from Chad myself (and sounds like you aren’t either), so we’re really not in a position to speculate on that. I do know that it’s quite common for one culture to have values or think in ways that are unintuitive to another culture.
Yeah, I grew up poor in the 3rd world (not quite Chad level though) and even the upper class culture of my own country was almost alien for us and vice versa... Imagine the 1st world.
Pretty sure the poor women in Chad with no access to healthcare and quality nutrition have quite a bit to lose, and they don't have a choice not to risk it.
Who do you think is their perceived neighborhood in time and space?
(edit) And moreover, they still need their children to help with their work... So honestly, any analysis that doesn't take this huge confounding variable is just silly
