High cost of fruits, vegetables linked to higher body fat in young children
Date:2/20/2014

Washington, D.C.--High prices for fresh fruits and vegetables are associated with higher Body Mass Index (BMI) in young children in low- and middle-income households, according to American University researchers in the journal Pediatrics.

"There is a small, but significant, association between the prices of fruit and vegetables and higher child BMI," said Taryn Morrissey, the study's lead author and assistant professor of public administration and policy at AU's School of Public Affairs (SPA).

Morrissey said that when the prices of fruits and vegetables go up, families may buy less of them and substitute cheaper foods that may not be as healthy and have more calories.

"These associations are driven by changes in the prices of fresh fruits and vegetables rather than frozen or canned," said Alison Jacknowitz, a co-author of the study and an associate professor of public administration and policy at SPA.

BMI is a reliable indicator of total body fat, which is related to the risk of life-threatening diseases. More than 26 percent of 2- to 5-year-old children nationwide were considered overweight, defined as having a BMI above the 85th percentile, in 2009 and 2010, up from 21 percent a decade earlier.

The researchers linked data from the Early Childhood Longitudinal Study-Birth Cohort, a nationally representative study of children from infancy to age 5, to local food price data from the Council for Community and Economic Research (C2ER) Cost-of-Living Index. The study focused on households under 300 percent of the federal poverty line, or a family of four earning $70,650 in 2013.

While, in general, food prices have trended downward in recent decades, particularly the prices of snacks and sugar-sweetened beverages, the real prices of restaurant meals and fruits and vegetables have increased. Fruit and vegetable prices increased by 17 percent between 1997 and 2003 alone. Children living in areas with hig
