Adequate micronutrients intakes in pregnancy requires major changes in the quality of the diet
Abstract
Introduction: Maternal nutrition is critical to the health of both
mother and offspring. Intakes of micronutrients such as iodine, calcium,
iron, folate and vitamin D play an important role in preventing
adverse pregnancy and birth outcomes, however there is a paucity of
data on the nutritional adequacy of diets during pregnancy.
Objectives: Our objective was to identify to what extent pregnancy
reduces the nutritional adequacy of the expecting mother’s diet
and if this nutritional gap can be resolved by simple quantitative or
qualitative changes in the diet.
Method / Design: Using a comprehensive probabilistic approach,
the PANDiet scoring system, we evaluated the observed nutritional
adequacy of diets of French and American women of childbearing
age (n=344 and n=563) participating in ENNS and NHANES and we
simulated the changes in adequacy in all nutrients and the final overall
PANDiet scores of women of childbearing age who would remain on
their diet during pregnancy. Then, by either increasing the quantity
of consumed foods or using snacks recommended during pregnancy,
we simulated the effect of a 150-kcal increase in the energy intake of
French women of childbearing age.
Results: Simulation of pregnancy in women of childbearing age
lowered the probabilities of adequacy for the intake of some nutrients
(8 out of 34 in France including folate, vitamin D and iodine, and 9
out of 30 in the US including folate), resulting in a decrease in the
overall PANDiet score, which was similar in both countries. Simulated
150-kcal increases in energy intake, with an increase in the quantity of
food consumed or using recommended snacks only partially corrected
this decrease. Indeed, those snacks failed to address the decrease in
adequacy related to some of critical micronutrients during pregnancy.
Conclusions: Pregnancy induces an important nutritional gap,
which is not efficiently addressed with simple generic dietary advice.
