The Strength of No Association between Diet Quality Indices and Simple Indices of Overweight/Obesity

In a recent issue of AIM, I read an article written by Asghari, et al. which tried to explain if diet quality is associated to simple indices of overweight/obesity. It is not necessary to emphasize that both childhood and adulthood obesity are of growing concern in the whole world. Reilly and Dorosty in 1999 explained an epidemic of childhood obesity in UK and several other studies i.e. Kelishadi, et al. (2003), Dorosty, et al. (2002), and Maddah (2008) suggest an increasing prevalence of childhood obesity in Iranian children too. Many other studies confirm that obesity prevalence in adults is increasing very quickly. Ayatollahi and Ghoreshizadeh (2010) have shown that obesity prevalence in Shirazi men has doubled (from 4.7% to 10.5%) and in women increased more than four times (from 5.1 to 22.5%) during last 14 years. WHO European Region Office now warns a tripling in obesity prevalence in the whole world in the 21st century.
