Objective Anaemia is the main nutritional deficiency in Brazil, and a prevention and control programme (National Program for Iron Supplementation) has been developed since 2005. Studies on the temporal evolution of anaemia prevalence contribute to assessment of the effectiveness of the actions undertaken. The present study aimed to identify the prevalence and temporal trend of anaemia in children. Design Study based on two cross-sectional household surveys carried out in 2005 and 2015. Anaemia was defined as Hb ® ). Trend analysis was performed using the prevalence ratio (PR), calculated by Poisson regression with a robust adjustment of the variance. Differences were significant when P Setting Alagoas, Brazil. Subjects In total, 666 and 782 children in the first and second Alagoas State Health and Nutrition Survey, respectively (probabilistic samples). Results In 2005 and 2015, anaemia prevalence was 45·1 and 27·4 %, respectively (−39·1 %; PR=0·61; 95 % CI 0·52, 0·70). In both surveys, children aged ≤24 months were more affected ( P 24 months (67·2 v . 40·7 %; 27·0 v . 19·3 %, respectively). Conclusions The prevalence of anaemia reduced significantly in the evaluated period. Thus, it may no longer be a severe public health problem but can instead be considered a problem of moderate magnitude. It remains, however, above the level considered acceptable according to WHO criteria. These results justify the implementation of prevention and control actions
