Professor Lewis Halsey from the University of Roehampton and his colleagues used data from the World Health Organization and foreign authorities to see how height and weight varied depending on living conditions, writes TheGuardian..

It found that people living in countries with low Human Development Index (HDI) scores are more likely to suffer from infectious diseases, chronic poor nutrition and greater disease severity than people living in countries with high HDI scores..

An analysis of records from dozens of countries found that for every 0.2 point increase in FDI, women were on average 1.7 cm taller and 2.7 kg heavier, while men were 4 cm taller and 6.5 kg heavier.
