Background: Human milk is the optimal nutrition for newborns and infants during the first period of their life – from birth to 6-th month. It contains a uniquely quantitative and qualitative balanced nutrients profile. Composition of breast milk is dynamic and may vary according to maternal nutritional status. Objective: The aim of this study was to investigate associations between human milk composition and maternal nutritional status. Material and methods: One-day milk samples were provided by exclusively breastfeeding mothers (n=40) at the first month of lactation. Protein – total and true, fat, carbohydrate, dry matter and energy content were determined using the Human Milk Analyzer by MIRIS. The anthropometric measurements (current body weight, height) were used to calculate current body mass index (BMI). On this basis, we assessed nutritional status of examined population. Results: For the majority of women (75%, n=30) currently BMI value was in range of 18.5-24.9 kg/m2, for the rest of women it was ≥ 25 kg/m2. The median macronutrient composition per 100 ml of mature breast milk was 7.0 g for carbohydrate, 1.1 g for protein, 3.5 g for fat, 11.9 for dry matter and energy content was 66.0 kcal. Maternal body mass index was positively related to lipid, dry matter and energy breast milk content (p<0.05). Conclusions: The majority of examined women in the first month of lactation was in normal state of nutrition. For the rest of women BMI values indicated for overweight. Our results confirm correlation between human milk composition and maternal nutritional status, especially in matters of energy value and fat content in human milk.

Background. Adequate nutrition and nutritional status during pregnancy are essential for mother’s health and foetus development. Due to increased demands, pregnant women are vulnerable to inadequate nutritional status and paradoxically it may also affect overweight women. Objective. The aim of the study was to evaluate energy and nutrients intake in the group of pregnant women in relation to nutritional standards and pre-pregnancy BMI. Material and methods. The study included 90 women, during the third trimester of pregnancy, recruited from Warsaw antenatal classes. The anthropometric data gathered in the research were used to calculate BMI value before pregnancy. Pre-pregnancy BMI was categorised as: normal weight (BMI=18.5-24.9 kg/m2, n=47) and overweight (BMI ≥25.0 kg/m2, n=43). The assessment of women’s nutrition was based on 3-days dietary record. Due to heterogeneous variances, differences between groups were assessed using Mann Whitney U test, p<0.05 was considered as significant. Results. The mean intake of energy, protein, fat and carbohydrates in the overweight women were significantly higher than in healthy weight women (p<0.05). Most of the healthy weight women did not reach EAR standard for vitamin D (79.5%), whereas in overweight group it was 41.3%. Conclusions. Despite the fact that intakes of energy and all nutrients were higher in overweight women than in normal weight ones, we observed that women in both groups had risk of insufficient supply of energy, iodine, potassium and vitamin D. For this reason, accurate nutritional assessment should be an integral part of obstetric care.

Background. Obese children are predisposed to vitamin D deficiency. Most of the findings suggest that requirement for vitamin D is increased in obese children due to this vitamin sequestration in adipose tissue. Objective. The aim of the study was to evaluate dietary intake of vitamin D in children with simple obesity in relation to nutritional standards. Materials and Methods. The study included 73 children aged 1-3 years: 38 with simple obesity (group I) and 35 non-obese ones (group II - control). The inclusion criterion for the obese group was BMI z-score > +2.0, for the control group BMI z-score between -1.0 and +1.0.The intake of vitamin D was estimated using the Dieta 5.0 software on the basis of 3-days dietary record. Outcomes were related to nutritional standards. Differences in intake of energy and nutrients between both groups were assessed using the Mann-Whitney test (statistical significance was set at p = 0.05). Results. Vitamin D intake in both groups was below the nutritional standards (10 μg/400 IU). Median values / interquartile ranges of results were 2.0 / 1.3-5.9 μg and 4.0 / 1.1-7.6 μg daily, for obese and non-obese children, respectively. The risk of deficient vitamin D intake was observed in 94.7% of obese children and in 82.4% of control group. The main dietary source of vitamin D in both groups was growing-up milk/Junior formula. The median intake of energy, protein, fat and carbohydrates in the obese children were significantly higher than in the control group (p<0.05). Conclusions. In obese children aged 1-3 years adequate dietary intake of vitamin D was not achieved. Similarly, the intake of vitamin D by normal weight children was lower than recommended. Consequently, it is necessary to provide products rich in vitamin D in the diet of toddlers, particularly obese.
