Maternal nutrition and inflammation have been suggested as mediators in the development of various adverse pregnancy outcomes associated with maternal obesity. We have investigated the relation between pre-pregnancy BMI, B vitamin status, and inflammatory markers in a group of healthy pregnant women. Cobalamin, folate, pyridoxal 5'-phosphate, and riboflavin; and the metabolic markers homocysteine, methylmalonic acid, and 3-hydroxykynurenine/xanthurenic acid ratio (HK/XA); and markers of cellular inflammation, neopterin and kynurenine/tryptophan ratio (KTR) were determined in pregnancy week 18 and related to pre-pregnancy body mass index (BMI), in 2797 women from the Norwegian Mother and Child Cohort Study (MoBa)...

Adequate supply of micronutrients during the first 1000 days is essential for normal development and healthy life. We aimed to investigate if interventions administering dietary doses up to the recommended nutrient intake (RNI) of iron and zinc within the window from conception to age 2 years have the potential to influence nutritional status and development of children. To address this objective, a systematic review and meta-analysis of randomized and quasi-randomized fortification, biofortification, and supplementation trials in women (pregnant and lactating) and children (6-23 months) delivering iron or zinc in doses up to the recommended nutrient intake (RNI) levels was conducted...

: Elevated circulating ferritin has been reported to increase the risk of gestational diabetes mellitus (GDM). When high ferritin translates into high iron stores, iron excess is also a condition leading to free radical damage. We aimed to evaluate the relationship between oxidative stress (OS) induced by iron status and GDM risk in non iron-supplemented pregnant women. METHODS: This was a pilot observational study conducted on 93 non-anemic pregnant women. Iron status was assessed at the first trimester of gestation...

PURPOSE OF REVIEW: Although the importance of optimizing mothers' health prior to conception and during pregnancy is now well accepted, recent data also implicate health and nutritional status of fathers as contributors to chronic disease risk in their progeny. This brief review will highlight recent epidemiological and experimental studies linking paternal overnutrition, undernutrition, and other forms of stress, to metabolic disease in the offspring. RECENT FINDINGS: The past 2 years have brought tremendous insights into the mechanisms by which paternal exposures can contribute to disease susceptibility in the next generation...

Obesity has reached epidemic proportions and pregnancies in obese mothers have increased risk for complications including gestational diabetes, hypertensive disorders, preterm birth and caesarian section. Children born to obese mothers are at increased risk of obesity and metabolic disease and are susceptible to develop neuropsychiatric and cognitive disorders. Changes in placental function not only play a critical role in the development of pregnancy complications but may also be involved in linking maternal obesity to long-term health risks in the infant...

Previously, a deterministic biologically-based dose-response (BBDR) pregnancy model was developed to evaluate moderate thyroid axis disturbances with and without thyroid-active chemical exposure in a near-term pregnant woman and fetus. In the current study, the existing BBDR model was adapted to include a wider functional range of iodine nutrition, including more severe iodine deficiency conditions, and to incorporate empirically the effects of homeostatic mechanisms. The extended model was further developed into a population-based model and was constructed using a Monte Carlo-based probabilistic framework...

Globally, vitamin A deficiency (VAD) affects about 19.1 million pregnant women. Its occurrence is classically associated with inadequate food intake and may also be associated with socioeconomic factors and the presence of infection. The aim of this study was to determine the factors related to serum retinol levels among pregnant teenagers. The sample consisted of 89 pregnant adolescents, from whom socioeconomic, obstetric, anthropometric, and food consumption data were collected. Serum concentrations of retinol and the supposed presence of infection were determined by high-performance liquid chromatography and C-reactive protein quantification, respectively...
