According to the OMS estimation, on the developing countries the iron deficiency anaemia affects close to 36% of the population, as long as on the developed countries its occurrence remains round 8%. Amongst the nutritional anaemias , iron deficiency anaemia is the most common, followed by megaloblastica anaemia , caused by , vitamin B12 or folic acid deficiency, that are essential for erythropoiesis. The present work had as the prime objective, analyse the prevalence of anaemia in Porto Novo, Santo Antão Island, besides describe the prevalence of anaemia according to sex, age and red blood cell morphology.In this study, a total of 473 blood samples collected in EDTA, routine anticoaguta were analysed, using the haematologic automatic counter SYSMEX KX-21N, between May and July 2010. The classification of anaemias was realized, according to the reference values determined by OMS to hemoglobin counting, so also the values of reference to MCV was established with support on researched bibliography and that of local reference values.The results indicated that, in the whole samples, 159 was male and 321 was female, in what, 41,01% (n=194) has presented anaemia, as long as 58,99 %(n=279) has presented normality. This was more prevalente on female, where we observed that 27,48% of women where anaemic. In pregnant the prevalence was 8,88%. The normocitic anae
