The prevalence of overweight/obesity has increased markedly
in the last 20 years in all age groups including children
younger than 5 years of age [1, 2]. Recent data have shown
that excessive weight gain and/or overweight/obesity in
the first several years of life are associated with increased
risks of subsequent obesity and unfavorable cardiometabolic
outcomes in childhood, adolescence, and adulthood [3–5].
Identifying risk factors in early prenatal and postnatal life
that are related to later obesity may lead to developing early
intervention strategies for primordial obesity prevention
