Maternal Nutritional and Water Homeostasis as a Presage of Fetal Birth Weight.

Birth weight is a key determinant of perinatal outcomes which affect physical development and metabolic function. In this study, we evaluated the potential role of maternal body composition and nutritional status in programing fetal birth weight. This was a longitudinal study that included 29 pregnant women and their full-term newborns. Maternal dietary energy and fluid intake and body adipose tissue were assessed. In addition, we measured the serum content of copeptin, aldosterone, and angiotensin II in maternal and umbilical cord blood. The measurements were done across the three trimesters of pregnancy, on average, at 11.6 weeks, 18.3 weeks, and 30.2 weeks. Each newborn's birth weight was determined at the percentile line, using the World Health Organization (WHO) standards based on the gestational age, gender, and weight. We found no appreciable relation of fetal birth weight to the maternal dietary and fluid intakes, and the content of angiotensin II, aldosterone, or copeptin. However, birth weight correlated with increases in body adipose tissue in early pregnancy stages. Further, birth weight correlated positively with copeptin and adversely with angiotensin II in cord blood. We conclude that the present findings may be helpful in the assessment of a critical level of body adipose tissue in women of child-bearing age, above which the potential risk of macrosomia appears. The female population of child-bearing age needs a continual update on the nutritional knowledge to prevent modifiable maternal and fetal perinatal complications.

Flavonoids intake among Polish and Spanish students.

BACKGROUND: Flavonoids are a group of bioactive compounds that are extensively found in foodstuffs of plant origin. Their regular consumption plays an important role in the prevention of degenerative diseases, particularly cardiovascular disease, and cancer. OBJECTIVE: The purpose of the study was to estimate dietary flavonoid intake among Polish and Spanish students and to establish the main dietary sources of flavonoids. MATERIAL AND METHODS: This study included 91 Polish and 60 Spanish students. Dietary data were collected using a food frequency questionnaire. The dietary USDA Database for the flavonoid content of selected foods was used to calculate daily and weekly flavonoid intakes by the subjects. RESULTS: The average flavonoid consumption in the Polish students was 801 mg/day, and in Spanish students 297 mg/day. Food categories such as beverages, vegetables and fruits were found to be significant sources of flavonoids, of which tea, oranges, orange juice, dried parsley and oregano were the main contributors among Polish students and oranges, tea, chick-peas, orange juice and dried parsley were the main sources of flavonoids among Spanish students. CONCLUSIONS: Flavonoid consumption in Polish students was more than two times higher than in Spanish students. Compared to other population studies consumption of flavonoids in both students groups was adequate.
