The paper, published in Nature's International Journal of Obesity, looks at the relation between early childhood socioeconomic status (SES) -- as measured by maternal education levels and household income -- and later development of childhood overweight and obesity in seven cohorts of children from high-income countries.

Social inequalities were evident across all cohorts, with greater risk of overweight and obesity linked to lower levels of maternal education in early childhood. There was also a link to household income, but it was less robust.
