Haemoglobin concentrations in pregnancy and respiratory and allergic outcomes in childhood: Birth cohort study.

ABSTRACT:

Background

Limited epidemiological evidence suggests that low maternal iron status and anaemia in pregnancy may increase the risk of childhood respiratory and allergic outcomes.

Objectives

To investigate the relation between maternal haemoglobin concentrations in pregnancy and childhood respiratory and allergic outcomes.

Methods

In the Avon Longitudinal Study of Parents and Children (ALSPAC), we examined associations of maternal haemoglobin concentrations (g/dL) in pregnancy with hayfever, eczema, wheezing, doctor-diagnosed asthma, allergic sensitisation and total IgE at 7 years, and with lung function at 8-9 years in the offspring, after controlling for potential confounders (N = 3234-5335).

Results

Maternal haemoglobin was not associated with offspring hayfev
