a Energy intake data
(MJ/d, kJ/kg/d, × BMR) expressed as weighted means. s.d. estimated from 
(n = number of studies). For
studies where s.d. was not reported the mean CV of other studies in that group was
assumed.
b Percentage difference = (Energy intake
- FAO/WHO/UNU estimated requirement)/estimated requirement × 100.
