Poor diets for school-age children may contribute to an average height gap of 20cm (7.9in) between the tallest and shortest nations, an analysis suggests.
It reports that in 2019 the tallest 19-year-old boys lived in the Netherlands (183.8cm or 6ft) and the shortest lived in Timor Leste (160.1cm or 5ft 3in).
Meanwhile the UK’s global height ranking fell, with 19-year-old boys being 39th tallest in 2019 (1.78m or 5ft 10in) from 28th tallest in 1985.
The study appears in The Lancet.
