The gap in height between school-age children in the tallest and shortest nations has indicated poor diet as a factor. Weight also varied hugely.

Researchers led by Imperial College London analysed data from more than 65 million children and adolescents aged 5 to 19 from nearly 200 countries between 1985 and 2019.

Global height ranking for the UK fell: 19-year-old boys were 28th tallest in 1985 at 176.3 cm, but 39th in 2019 at 178.2 cm. And 19-year-old girls went from 162.7cm (42nd) to 163.9 cm (49th)

Having 1, or 3 or more, children was associated with an increased risk of depression – between 11% and 27% – compared with having none.

For single parents, having children was associated with an overall increased risk of depression. More than 52,000 middle-aged and older adults took part
