It may be the boys who are at the greatest risk.
Girls fall behind at an early age compared to their male peers around the world. The semi-nomadic Maasai tribe of Kenya and Tanzania are known for their male warriors, the morani. The masculine culture would lead one to conclude that the problems start with the girls, but it is the Maasai boys who are in trouble.
Boys traditionally take care of the cattle during the day, leaving them with little to eat for a day that requires a lot of walking and work. An analysis of the body mass index (BMI) of school-age boys and girls (between seven and nineteen years old) in the region shows a stark divide. Malnutrition is striking at a point of vital development for all children.
