Selected highlights from a new study on immigration, health and gender roles:

• Mexican wives who stay home when their husbands immigrate to the United States for work have poorer mental health than a comparison group.
• Shifting gender roles seem to be equally as stressful as the husbands' absence.

"Popular American psychology would suggest that their newfound independence might ease the stress of single-handedly managing the household. Being apart from their husbands, who go to the United States to work, does nothing beneficial for their mental health." - Jared Wilkerson, lead study author
