Marginal biotin deficiency during normal pregnancy
Pregnancy teratogenicity biotin deficiency 3-hydroxyisovaleric acid women
2016/12/17
Background: Biotin deficiency is teratogenic in several mammalian species. Approximately 50% of pregnant women have an abnormally increased urinary excretion of 3-hydroxyisovaleric acid (3-HIA), ...
Leptin and maternal growth during adolescent pregnancy
Adolescent pregnancy leptin growth birth weight low birth weight fetal grow restriction body composition
2016/6/8
Background: Maternal growth on the basis of knee height
occurs in nearly 50% of pregnant teenagers and is associated
with greater gestational weight gain and accrual of subcutaneous
fat in the moth...
Multifrequency bioelectrical impedance analysis in women with a normal and hypertensive pregnancy
Pregnancy multifrequency bioelectrical impedance analysis gestational hypertension
2016/6/8
Background: An increase in total body water is common in normal
pregnancy. It is thought to be an important mechanism of
maternal adaptation to pregnancy.
Objective: The aim of the present study wa...
Folate absorption in women with a history of neural tube defect–affected pregnancy
Folate neural tube defect absorption bioavailability, stable isotopes women
2016/6/7
Background: The risk of neural tube defects (NTDs) is significantly
reduced by supplemental folic acid. NTD risk may be
associated with impaired absorption of polyglutamyl folate, the
primary form ...

2016/6/7
Background: Anemia in pregnancy is a major public health
problem in developing countries. In sub-Saharan Africa, such

Iron requirements in pregnancy and strategies to meet them
Iron requirements absorption pregnancy, strategies therapy women iron fortification
2016/6/7
Iron requirements are greater in pregnancy
than in the nonpregnant state. Although iron requirements are
reduced in the first trimester because of the absence of menstruation,
they rise steadily th...
Iron needs during pregnancy: do we need to rethink our targets?
Iron anemia requirements pregnancy supplementation, hemoglobin
2016/6/7
This paper argues that current estimates of the
need for absorbed iron, estimates of iron absorption, and hence
estimates of iron requirements for pregnant women greatly
depend on what is determine...
Significance of an abnormally low or high hemoglobin concentration during pregnancy: special consideration of iron nutrition
Hemoglobin anemia polycythemia iron defi- ciency birth outcomes preeclampsia iron supplementation
2016/6/7
An association between moderate anemia and
poor perinatal outcomes has been found through epidemiologic
studies, although available evidence cannot establish this relation
as causal. Anemia may not...
Nutrition in pregnancy: mineral and vitamin supplements
Nutrition vitamins trace elements minerals, pregnancy requirements
2016/6/7
Pregnancy is associated with physiologic
changes that result in increased plasma volume and red blood
cells and decreased concentrations of circulating nutrient-binding
proteins and micronutrients....
Physiology of pregnancy and nutrient metabolism
Pregnancy protein energy basal metabolism, food intake physical activity physiology
2016/6/7
Pregnancy consists of a series of small, continuous
physiologic adjustments that affect the metabolism of all
nutrients. The adjustments undoubtedly vary widely from
woman to woman depending on her...
Energy adaptations in human pregnancy: limits and long-term consequences
Energy adaptation energy metabolism, pregnancy fetal growth women
2016/6/7
The very slow rate of human fetal growth generates
a lower incremental energy stress than in any other mammalian
species. This creates a situation in which adaptive changes
in metabolic rate and in...
Pregnancy weight gain: still controversial
Weight gain pregnancy birth weight postpartum weight preterm delivery maternal health Institute of Medicine
