Somatotype, diet and nutritional status of women

Abstract The relationship between energy value and nutrients intake and the body shape and size parameters (weight, height, waist and hip circumferences) has become an interesting research area for nutritionists and dieticians. The aim of this study was to determine the relationship between the body shape and size parameters (weight, height, waist and hip circumferences), somatotype (according to the Rohrer (RI) index) and energy value and nutrients intake of women. The study was conducted in 2014 and 2016 on 148 female volunteers aged 57-88 from the Mazovian and Lublin province (Poland). Sample selection was targeted at elderly people with different body types. The exclusion criteria were: multi-organ failure, cancer and disability. Then among the subjects, a survey was conducted, that included demographic data, lifestyle, health status and vitamins and minerals supplements use. Food intake has been assessed using a 3-day dietary food records. The somatotype was determined using the RI with the Curtis key, classifying the subjects as ectomorphic (n=30), mesomorphic (n=31) and endomorphic (n=87). The somatotype was significantly related to place of residence, physical activity, waist and hip circumference, WHR and BMI index, total protein intake, animal protein intake, vitamin E intake (p≤0.05) and to fat, phosphorus and thiamine intake (p≤0.1). The obtained results showed that the place of residence, physical activity, chronic diseases, the use of specialized diet, body weight fluctuations, BMI and WHR were different depending on the somatotype in the examined group of women. Endomorphic subjects had significantly greater waist and hip circumference and diastolic blood pressure compared to the other somatotypes. The somatotype had only a significant effect on total protein, animal protein and vitamin E intake, and ectomorphic elderly women may be particularly susceptible to nutrient deficiencies. Due to the risk of macronutrient, vitamin and mineral deficiencies in the diets of the examined women, it seems necessary to educate this group as well as caregivers and doctors in the area of nutrition adapted to the needs of the elderly.

Fruit and vegetable consumption and proper nutrition in patients with cardiovascular diseases Aim.Assessment of the fruit and vegetable consumption and nutrient intake among patients with CVD. Materials and methods.Nutrient intake was assessed among 127 (32 women and 95 men; age: 62 ± 11 years) patients with CVD using 3-day dietary records method. Subjects with fruit and vegetables intake at least 400 g/d were classified as group I (fruit and vegetables intake according with recommendation), and others were classified as group II. Then, nutrient intake for both groups was compared with dietary recommendations. Results.The higher percentage of patients, who fulfilled dietary guidelines was observed in group I in the case of the intake of minerals and vitamins and fiber. Conclusions.Present studies have shown incorrect dietary intake among most patients with CVD, but the higher percentage of patients, who fulfilled dietary recommendations for minerals, vitamins and fiber was observed in group I.

Antioxidant Vitamins as Oxidative Stress Markers in Rat Plasma After Physical Exercise - a Short Report

Abstract The aim of the study was to verify the hypothesis that β-carotene, vitamin E, vitamin C administered individually or in combination may differently modify their levels in blood plasma being also markers of the oxidative stress. Male Wistar rats were supplemented antioxidants per os (α-to-copherol - 2 mg/d, ascorbic acid - 12 mg/d, β-carotene - 1 mg/d), both individually or in combination of 2 or 3, for 14 days. During experiment, half of the animals in each group (n=8) were subjected to treadmill exercise for 15 min at the speed of 20 m/min, to induce oxidative stress. Vitamins in rat plasma were assessed by the high-performance liquid chromatography (HPLC). Results suggest that vitamin E and C supplemented simultaneously may provide some benefit during physical exercise. The significant influence of administered α-tocopherol acetate and physical exercise on the level of α-tocopherol in the plasma was observed. Thus only the concentration of α-tocopherol in blood may be treated as a marker of oxidative stress.
