Diet and deprivation in pregnancy

Area of Science:

• Maternal and Child Health
• Nutritional Epidemiology
• Public Health

Background:

• Socio-economic deprivation is a known risk factor for adverse pregnancy outcomes.
• The specific role of nutrition as a mediator in this relationship requires further investigation.

Purpose of the Study:

• To investigate the association between socio-economic deprivation, nutritional status, and pregnancy outcomes in a UK cohort.
• To identify specific dietary patterns and nutrient deficiencies linked to deprivation and their impact on birth outcomes.

Main Methods:

• Prospective cohort study of 1461 singleton pregnancies in Aberdeen, UK (2000-2006).
• Assessed nutrient intake, supplement use, B vitamin and homocysteine status, birth weight, gestational age, neonatal treatment, and socio-economic deprivation.
• Statistical analysis adjusted for confounders like smoking, marital status, and parity.

Main Results:

• Deprived women were younger, less likely to take folic acid, and had diets low in protein, fiber, vitamins, fruits, and vegetables.
• Deprivation was associated with preterm birth and increased need for neonatal treatment.
• Low birth weight was linked to diets deficient in vitamin C, riboflavin, pantothenic acid, and sugars, even after adjusting for deprivation and other factors.

Conclusions:

• Pregnancy deprivation is associated with poor nutritional intake, contributing to health inequalities in pregnancy outcomes.
• Targeted nutritional interventions for disadvantaged women of childbearing age may improve pregnancy outcomes and reduce disparities.
