Average Czech newborn baby weighs 3.3 kg, multiple births decreasing

The average weight of a newborn baby in the Czech Republic has held steady at around 3.3 kilograms over the past ten years, the Czech Statistical Office (ČSÚ) said on Monday.

The proportion of multiple births has fallen in that period – from 2.1 per cent of live births in 2007 to 1.4 per cent last year – a change that could signal a drop in the use of fertility treatments, which increase the chances of having twins.

The majority of babies were from 49 to 51 centimetres long at birth and were born in the 39th or 40th week of pregnancy. Last year, 505 children were born in the Czech Republic who weighed less than one kilogram, up from 430 in 2007.
