Mexican-American Children Obesity Rates Linked to Generation and Economic Status

Children of Mexican-origin have the highest rates of childhood obesity in the U.S., a new study by Penn State suggests.

Researchers were curious to find out why children who are first- or second-generation Mexican-American are more likely to be overweight than their peers in Mexico.

“The risks of obesity are stratified among Mexican-origin children according to their generation status – the number of generations their family has been in the U.S.,” said Molly Martin, associate professor of sociology and demography at Penn State.

To find answers, Martin and her team used data from the National Health and Nutrition Examination study “to test associations between generational status, nutrition of Mexican-origin children between ages 5 and 17, and the family’s socioeconomic status.”

Based on the results, the team of researchers theorized children born and raised in Mexico were more exposed to traditional Mexican food rich in vegetables and fruits which help them develop a preference for healthier foods. Meanwhile, Mexican-American children found typical American fast food more appealing. “Children of immigrants often want to fit in with their U.S. peers, and part of fitting in is eating the same foods,” Martin said.

The team of researchers also concluded the level of education and income of Mexican-origin parents also plays a role in the health of children.

“Immigrant families that successfully integrate into American society have better outcomes, while those families that struggle economically face additional risks, including their children’s health,” Martin said.
