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.

Lifestyle Intervention Program for Amelioration of Dysmetabolism in Overweight Women.

Overweight and obesity, a cluster of multiple risk factors for atherosclerosis such as elevated blood pressure, elevated glucose level, and dyslipidemia, increase the risk of all-cause mortality and cardiovascular morbidity and mortality. Physical activity and a proper diet are essential preventive measures. The aim of the study was to evaluate the effects of a two-month intervention program consisting of a low-caloric diet (1,500 kcal) and increased physical activity on the anthropometric parameters, body composition, resting metabolic rate, and maximum oxygen uptake. The study was conducted in 22 women aged 20-38 with diagnosed overweight or obesity. We found that after completing the eight-week-long intervention program, there were significant changes in body composition, consisting of a smaller proportion of body fat and increased lean body mass. Further, we observed a decrease in body weight by 4.3 ± 2.5 kg (p < 0.01), a reduction in waist and hip circumference of 2.6 ± 4.5 cm (p < 0.01) and 4.4 ± 2.9 cm (p < 0.01), respectively, and an increase in maximum oxygen uptake by about 5.2 ± 8.4 ml/kg/min (p < 0.01). We conclude that the intervention program consisting of counseling on diet and physical activity may be highly motivational for patients with excess body weight and care givers should give it a try before commencing more aggressive psychopharmacological therapies.
