There is “ample room for improvement” in the diet and activity levels of preschool-age children, reports Amrik Singh Khalsa, MD, fellow in the Division of General and Community Pediatrics.

Khalsa’s study, published online in Preventive Medicine Reports, found only one of nearly 400 preschoolers following daily 5-2-1-0 obesity prevention guidelines. Khalsa’s team obtained objective measures of dietary intake, body mass index (BMI), activity levels, and screen time in 398 preschool children over 24 hours, in day care and at home.

Among their findings: one of every four children had a BMI in the overweight category; just 17 percent ate at least five servings of fruits and vegetables; and fewer than 1 percent met activity recommendations. 

5-2-1-0 daily guidelines recommend at least five servings a day of fruits and vegetables, fewer than two hours of screen time, one hour of physical activity and no sugar-sweetened beverages.
