Recently a new simply calculated index of body composition -a body shape index (ABSI) has been introduced as an index more reliable than BMI of association between body composition and all-cause mortality. However, until now associations between ABSI and metabolic risk factors have not been evaluated. A total of 114 male university students not engaged in any planned physical activity participated in the present study. Anthropometric measurements (weight, height, waist circumference) were recorded. Body mass index (BMI) was calculated from weight and height, body shape index (ABSI) was calculated from waist circumference, weight, height and BMI. Blood was withdrawn after an overnight fast from the antecubital vein. Triacylglycerols, total cholesterol and HDL-cholesterol levels in plasma were determined using colorimetric methods and Randox commercial kits. Plasma LDL-cholesterol concentrations were calculated according to the Friedewald formula. Circulating insulin was assayed using a standard radioimmunological method with monoclonal antibodies against insulin and BioSource commercial kits. BMI was slightly, but significantly correlated only with circulating TG (r=0.330, p < 0.001) In contrast, ABSI was slightly, but significantly correlated with plasma levels of insulin (r=0.360, p<0.001), TC (r=0.270, p<0.002), LDL-C and non-HDL-C (r=0.300, p<0.001). In participants at the upper quartile of BMI circulating TG was higher (by 50%, p<0.05) than in their counterparts at the lower BMI quartile. Subjects representing the upper quartile of ABSI were characterized by higher plasma levels of insulin, TC, LDL-C and non-HDL in comparison with subjects at the lower ABSI quartile. (by 92 %, 11. %, 29 % and 21 % respectively, p<0.001). ABSI, a new simply calculated index of body fat seems to more accurately depict the variability in circulating insulin and lipoproteins than BMI at least in young, healthy male subjects.

Limited data have indicated that body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR) and waist to height ratio (WHtR) of athletes and young adults provide misleading results concerning body fat content. This study was aimed at the evaluation of the relationship between different surrogate indices of fatness (BMI, WC, WHR, WHtR and body adiposity index (BAI)) with the percentage of body fat in Polish students with respect to their sex and physical activity.

Improper dietary habits among students are a growing public health concern, as they contrib-ute to diet-related diseases. This study aimed to assess the frequency of food consumption among students, with analysis of factors influencing their choices and potential health conse-quences, particularly regarding health-promoting properties of the diet. A total of 1269 students (436 women and 833 men) from the Józef Piłsudski University of Physical Education in Warsaw participated in the study. The average age was about 20 years, mean body weight 72 kg, and mean height 177 cm. Eating habits were evaluated using the validated Food Frequency Questionnaire (FFQ-6), and diet quality was assessed with the Pro-Health Diet Index (pHDI-10). Significant gender differences were found in the consumption of refined bread, butter, fruits, vegetables, red meat, and poultry. Men also consumed fruit juices, sweetened beverages, beer, wine, and vodka more frequently than women. Overall, the majority of participants' diets had a low probability of health-promoting properties. In conclusion, student diets show limited health-promoting potential and indicate a high pre-disposition to diet-related diseases. These results highlight the importance of implementing educational programs promoting rational nutrition and healthy lifestyle choices in the student population.

Background/Objectives: Eating habits and behaviors play a central role in maintaining health and overall well-being. In the case of young students, they affect not only appearance and general mood but also cognitive ability, concentration, and broader learning ability. For this reason, it is essential for young people to have well-balanced and wholesome diets. Methods: The study included 186 Polish and 136 Greek university students majoring in sports. The research tool was the validated survey questionnaire FFQ-6, and the data collected were additionally used to calculate the healthy diet index (pHDI-10). Results: Based on the analysis of the collected data, the dietary habits of the students surveyed were assessed, taking into account, among other things, the frequency of consumption of sweets, salty snacks, processed foods, and sweetened drinks, but also healthy products, including vegetables and fruit or vegetable and fruit juices. The data collected made it possible to determine an index of the health value of the participants’ diet. Conclusions: The analysis of the collected data led to the conclusion that, more often than their Greek peers, Polish university students tend to reach for sweets, salty snacks, or sweetened drinks. Greeks were more likely to choose fruit and vegetables and vegetable and fruit juices. However, among both Poles and Greeks, the index of the health-promoting value of the diet is low, indicating a high risk of diet-related diseases of lifestyle. Similar trends can be observed among students of almost all nationalities, which makes it reasonable to consider the implementation of appropriate educational programs on nutrition and healthy lifestyle principles in general.

It is well documented that regular physical activity has a beneficial effect on human health by affecting the metabolic processes that are of fundamental importance in the body’s functions, such as insulin sensitivity and glucose disposal, as well as lipid and lipoprotein turnover. On the other hand, there is a wealth of studies which indicate that strenuous, regular physical activity, such as that performed by high performance athletes, may be detrimental for the athletes’ health especially in women. This review focuses on the factors that contribute to health problems in female athletes, named the female athlete triad, which includes excessive dieting, menstrual dysfunctions (anovulatory menstrual cycles, oligomenorrhea, amenorrhea) and a low bone mineral density (BMD). As a result of these factors, women who participate in sports, especially those focused on leanness, need special attention and education from health professionals, coaches and the athletes themselves to prevent the detrimental effects of an inadequate energy supply against high energy demands
