Not too many years ago, when a child went to a dietician, it was because he or she was too thin. Now, dieticians say they are seeing more overweight, and even obese children. The Centers for Disease Control found in 2010 that 1 in 7 preschool age children is obese. With extra weight comes increased health risks, and to treat a problem, it’s better to catch it early. The Purchase Area Health Education Center is working with several counties in the region to find children who may be at risk for cardiovascular problems.
