- Malnutrition: The nutritional assessment of children aged 24–59 months, a weight-for-height (W/H) index, will be calculated. This index is expressed in standard deviations of a normalised distribution of a reference population 38 (National Centre for Health Statistics, USA). Children under 5 years old with a Z-score inferior to -2 will be excluded. For children over 5 or adults, the clinical examination will be considered.
