Scatter plot depicting the relationship between haemoglobin concentration and mean corpuscular volume in 6–9-year-old rural primary school children (n = 860) in eight primary schools in Hai Phong City, Vietnam. Microcytic anaemia was defined as Hb < 115 g/L and MCV < 80 fL (, n = 77, 9.0%), normocytic anaemia as Hb < 115 g/L and MCV 80–90 fL (, n = 59, 6.9%), macrocytic anaemia as Hb < 115 g/L and MCV > 90 fL (n = 0, 0.0%), and no anaemia was defined as Hb ≥ 115 g/L (, n = 724, 84.1 %).
