Association between iron deficiency anaemia and complementary feeding in children under 2 years assisted by a Conditional Cash Transfer programme.

OBJECTIVE

To evaluate the association between Fe deficiency anaemia (IDA) and complementary feeding in children under 2 years old assisted by the Conditional Cash Transfer programme, Bolsa Família (BFP).

DESIGN

Cross-sectional study. Data were obtained through a standardised form, questionnaire to assess the eating habits of children under 2 years of age, capillary Hb (HemoCue®) and the Brazilian Household Food Insecurity Measurement Scale. Associations were calculated using hierarchical Poisson regression, adjusted at the last level by socio-economic, demographic and environmental variables from previous hierarchical levels.

SETTING

Six municipalities from the State of Alagoas, Brazil.

PARTICIPANTS

Children aged 6-24 months assisted by BFP.

RESULTS

A total of 1604 children were evaluated, among whom 58·1 % had anaemia. A higher number of food groups consumed (prevalence ratio (PR) = 0·97; 95 % CI 0·95, 0·99; P = 0·009), the consumption of dairy (PR = 0·86; 95 % CI 0·79, 0·84; P = 0·001) and meat (PR = 0·90; 95 % CI 0·83, 0·99; P = 0·030) in addition to bottle feeding (PR = 0·88; 95 % CI 0·82, 0·96; P = 0·004) were associated with a lower prevalence of IDA.

CONCLUSIONS

IDA is still a serious public health problem in children under 2 years old assisted by BFP in Alagoas. We highlight the importance of promoting complementary feeding based on a diversified dietary intake, as well strengthening prophylactic supplementation programmes to increase children's adherence in conjunction with the implementation of food and nutrition education to help reduce the prevalence of this condition.
