Financial difficulties, smoking habits, composition of the diet and birthweight in a population of pregnant women in the South West of England. ALSPAC Study Team. Avon Longitudinal Study of Pregnancy and Childhood.
OBJECTIVE
To investigate the relationships between self-assessed financial difficulties, diet in pregnancy and birthweight.


METHODS
Information on diet composition, difficulty in affording food, smoking habits and parity was collected by self-completion questionnaires at 32 weeks of pregnancy. Information on birthweights was obtained from hospital records.


METHODS
A geographically defined population 11833 pregnant women resident in the South-West of England.


METHODS
Nutrient intakes, food choices and birthweight.


RESULTS
Women with greater difficulty in affording food had lower intakes of protein, fibre, vitamin C, niacin, pyridoxine, iron, zinc, magnesium and potassium than did women with little or no difficulty. They were more likely to use cooking and spreading fats with a high saturates content, and less likely to eat fish, fruit, vegetables and salad. In a multivariate analysis including parity and smoking status, financial difficulty was found to have no significant relationship with birthweight.


CONCLUSIONS
The quality of diet in pregnancy falls with increasing difficulty in affording food. However, this does not appear to affect mean birthweight of infants born after 32 weeks gestation.
