Background. Anthropometric parameters provide a lot of information about body composition and nutritional status, regardless whether they relate to obesity or malnutrition. The aim of this study was to assess the relationship between nutritional status, dietary habits and body image perception among male Polish adolescents. Material and methods. The study population primarily comprised 322 male adolescents aged 17-18 years from Western Poland, with thirty respondents however, dropping out of the study during its course. Anthropometric appraisal included body height and weight, four skinfolds thickness, circumferences of the waist, hip and arm. The percentage of fat mass and arm muscle area was calculated. The self-administrated questionnaires were used to estimate the frequency and quality of food intake, as well as the perception of body image of the studied subjects. In order to identify the similarity of nutritional habits and anthropometric parameters of adolescent males, cluster analysis was applied. Results. The mean values of body weight and height were close to 50th percentile. However, 10.7% of males were underweight, 10.7% overweight and 1.3% obese. The tendency to underestimate own level of fatness among overweight and obese subjects was observed. Over 90% of the studied subjects consider "average" silhouette as an ideal. Conclusions. Polish obese and overweight adolescents show a tendency to underestimate their level of fatness and perceive themselves as "average", despite possessing an excessive amount of body fat.
This study aims to find relationships between nutritional status, leptin and puberty. Methods. The research covered 66 healthy girls aged 9.8 ± 0.6 years, in prepubertal period. Body height, weight, arm circumference and skinfolds were measured, and serum leptin concentration was estimated. The evaluation of the pubertal stage and anthropometrical measurements was carried out again in a year's period. Results. During the observation, 32 girls reached the time of puberty (group I), while the other 34, at the same age, were still at prepubertal stage (group II). The girls in group II were shorter, lighter, had lower arm circumference, thinner skin fold on abdomen (p<0.02) and lower serum leptin concentration (p<0.003). Highly positive correlations between BMI, skin folds thickness and leptin concentration were proved. Conclusion. The results indicate relationships between the fat tissue amount, blood leptin concentration and puberty in girls.
Introduction. Anthropometric measurements and the BMI are taken into account in the process of developing physical fitness tests for children. Aim of Study. The aim of this study was to describe the relationships between the anthropometric characteristics (body mass, body height, length of lower and upper limbs), BMI and speed abilities of preschool boys and girls performing the 8-second skipping with hand clapping (8-s SHC) test. The increase in HR during the test was also determined. Material and Methods. The test involved 60 girls and 57 boys aged 68.2 ± 11.33 months (min. – 56, max – 89). Their body mass, body height, length of lower and upper limbs and BMI were determined, and their speed abilities were evaluated with a 8-s SHC test. The participants’ HR was measured before and after the test, and the exercise-induced increase in HR was calculated. The basic statistics were determined for all evaluated parameters and the coefficients of correlation between anthropometric features, HR, and the number of claps during the test were calculated. Results. Among the analyzed parameters, only body mass and BMI were significantly higher in boys than in girls. Mean HR increased during the 8-s SHC test in both girls and boys (to 149.40 and 152.9 bpm, respectively). The number of claps during the 8-s SK test increased significantly with an increase in the values of anthropometric measurements. Significant correlations between the analyzed parameters were not determined only for BMI and heart rate after the 8-s SK test. Conclusions. Anthropometric characteristics such as body mass, body height, length of lower and upper limbs significantly influenced the speed abilities of kindergarteners performing the 8-s SK test, whereas BMI was not significantly correlated with the results of the test.
Background. Polycystic ovary syndrome (PCOS) is a disorder often occurring in women at reproductive age. An important factor in PCOS pathogenesis is insulin resistance, which pronounces hyperandrogenism and leads to the development of various metabolic disorders. Objectives. The aim of this study is to determine the effect of reduction diet with low glycemic index (GI) on anthropometric parameters of women with PCOS and the assessment of the effectiveness of the diet on body mass and adipose tissue reduction. Material and methods. The study was performed on 24 women with PCOS diagnosed with Rotterdam’s criteria. Anthropometric measurements and bioelectrical impedance were performed. All participants received 7-day diet and recommendations relating to the change in lifestyle. After three months of using the dietary recommendations the measurements were repeated. Results. Statistical significance was observed for body mass (↓on average by 5.93 kg±2.95), BMI (↓2.14 kg/m2±1.2), circumference of: waist (↓7.7 cm±5.9), hip (↓4.8 cm±5.4), arm (↓1.9 cm±3.7) and measurements of skin fold under the shoulder blade (↓4.8 mm±4,6), above iliac crest (↓6.76 mm±5.7) and above triceps brachii muscle (↓5.25 mm±7.4). Considering body composition measurements, statistically significant were differences in the measurements of BCMI (↑18.042±8.8), TBW expressed in percentage (↑2.729±2.75) and in litres (↑0.071±5.15), FM in percentage (↓3.291±5.6) and in kg (3.354 kg±4.9). Conclusions. Body mass reduction using a rational diet with low GI is an effective method to support of PCOS treatment. Using reduction diet for three months together with increased physical activity enables to reduce body weight by on average 5.93 kg, which increases the chances to treat infertility in women. This should be the suggested type of diet in PCOS treatment.
Background. The formation and development of the metabolic syndrome (MetS) is largely caused by lifestyle factors. Many studies have shown that excessive consumption of simple carbohydrates, alcohol, salt, physical inactivity and smoking increase the risk of MetS. Objective. The aim of the study was to assess the nutritional status and its relationship with selected lifestyle factors in elderly people with MetS. Material and methods. 81 people aged 51-75 participated in the study. According to the guidelines, all tests were performed on an empty stomach. The comparison of individual quantitative variables between the groups was performed using the Student's t-test for independent measurements or using the Mann-Whitney U test. The relationship between quantitative variables was verified with the Spearman's correlation coefficient. All statistical tests were based on a significance level of p<0.05. Results. The BMI, the percentage of body fat and the waist circumference significantly exceed the norm for the population in the examined persons. The responses of respondents aged 51-65 show that 36% of people sweetened their drinks, 65.6% were salted their food, 51.6% consumed alcohol, and at the age of 66-75, respectively: 47.1%, 52.9%, 41.2%. There was no correlation between sweetening beverages and salting food and the concentration of glucose and lipids. However, a positive correlation was found between the amount of salt consumed and the heart rate (r=0.28, p<0.05). In both age groups, statistically significant differences in the concentration of triglycerides depending on alcohol consumption or non-consumption were found. Due to the lack of precise data on the amount of alcohol consumed, the correlation between alcohol consumption and the concentration of glucose and lipids was not analyzed. Physical activity was not undertaken by 39.1% of patients aged 51-65 years and 41.2% of patients aged 66-75 years. In the group of elderly people without physical activity, a statistically significantly higher glucose concentration was found in relation to those who were physically active (130 mg/dl vs. 105 mg/dl; p=0.031). Patients aged 51-65 who engaged physical activity had statistically significantly lower body weight, BMI, waist circumference and lean body mass, which requires further studies. Conclusions. The anthropometric indices and parameters of MetS patients indicated disturbances in the nutritional status. Unhealthy lifestyle was shown mainly in the younger group of patients 51-65 years old (they sweetened drinks more often, salted dishes, consumed alcohol). Patients with metabolic syndrome did not undertake physical activity as often as recommended.
