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.

Figure 11a Energy intake compared with expenditure estimated by doubly labeled water and heart rate monitoring, including stunted and underweight children, and current recommendations: boys (solid line: mean energy intake; interrupted line: FAO/WHO/UNU recommendations).

Figure 11b Energy intake compared with expenditure estimated by doubly labeled water and heart rate monitoring, including stunted and underweight children, and current recommendations: girls (solid line: mean energy intake; interrupted line: FAO/WHO/UNU recommendations).
