Skim Milk Does Not Prevent Obesity in Young Children
TUESDAY, March 19 (HealthDay News) -- For preschool children, consumption of 1 percent/skim milk is associated with overweight/obesity, according to a study published online March 18 in the Archives of Disease in Childhood.
Rebecca J. Scharf, M.D., M.P.H., from the University of Virginia School of Medicine in Charlottesville, and colleagues conducted a longitudinal study involving 10,700 U.S. children evaluated at age 2 and 4 years to examine the correlation between type of milk consumed and weight status.
The researchers found that most children drank 2 percent/whole milk at age 2 years (87 percent) and 4 years (79.3 percent). Compared with 2 percent/whole milk drinkers, those who drank 1 percent/skim milk had higher body mass index (BMI) z-scores across racial/ethnic and socioeconomic status subgroups. Increasing fat content in milk correlated inversely with BMI z-score in multivariate analysis. The odds of being overweight or obese were significantly increased for those drinking 1 percent/skim milk compared with those drinking 2 percent/whole milk (odds ratios at age 2, 1.64 and 1.57, respectively; at age 4, 1.63 and 1.64, respectively). Children drinking 1 percent/skim milk at ages 2 and 4 years were significantly more likely to become overweight or obese between the ages of 2 and 4 years, based on longitudinal analyses.
"In conclusion, we found that among preschoolers, consumption of 1 percent/skim milk was associated with overweight and obesity," the authors write. "Our data do not support 1 percent/skim milk consumption as the sole way to restrain gains in BMI among preschoolers."
