More than 30 per cent of children in the city have flat feet, a survey has found.
Of 576 school children from six primary and secondary schools examined, 34 per cent had flat feet, the study, conducted by a private health specialist centre, found.
Flat feet is a condition in which a foot does not have a normal arch on the inner side when a person is standing. It may affect one or both feet.
Feet with a low arch or no arch are referred to as flat feet or fallen arches.
The year-long study, which began last July, also found that most children with flat feet were aged between four and eight. More than 50 per cent of the children with flat feet were under eight.
'Younger children tend to suffer from flat feet because of baby fat between their foot bones. The arch in their feet will be formed and clearer in shape as their feet grow,' the centre's chief physiotherapist, Ada Yu Wing-cheung, said.
