1. Lifestyle characteristics of students who are overweight, obese, or have normal body weightČrtomir Matejek, David Kukovica, 2025, original scientific article Abstract: This study examines the differences in body composition and lifestyle habits between normal-weight (NW) and overweight/obese (OW&O) university students. A sample of fifty-five students aged 21–25 years completed validated questionnaires (HLPCQ, IPAQ-SF, WHO-5) and underwent body composition analysis using the InBody 270 device. Statistical analyses included independent sample t-tests and Cohen’s d effect sizes. OW&O students had significantly higher scores for body fat, fat-free mass, and skeletal muscle mass. While body composition differences were evident, lifestyle habits did not significantly differ between weight groups. Bias in lifestyle and well-being selfassessment calls for the development of more objective assessment tools and further research.

2. Sarcopenia, obesity, and their association with selected behavioral factors in active older adultsKaja Teraž, Miloš Kalc, Manca Peskar, Saša Pišot, Boštjan Šimunič, Rado Pišot, Primož Pori, 2023, original scientific article Abstract: Introduction: The number of obese people in the world is increasing, as is the number of sarcopenic people among the older adults. Although both states are concerning, they can be positively influenced by selected behavioral factors such as adequate nutrition and physical activity. We were interested in the prevalence of sarcopenic obesity in active older people and the influence of behavioral factors on this phenomenon.
Methods: The study included 38 older adults (21 women) with a mean age of 75.3 ± 5.0 years. Sarcopenic parameters were determined with different tests: Handgrip Test, Chair Stand Test, Gait Speed, Timed Up and Go Test, and Short Physical Performance Battery. Body composition was measured by dual-energy x-ray absorptiometry. Physical activity level was measured using accelerometers, and nutritional status was assessed using the Mini-Nutritional Assessment and MEDLIFE Index questionnaire.
Results: Of all included active participants (the average number of steps per day was 8,916 ± 3,543), 47.4% of them were obese. Of all included women, 52.4% were obese. Sarcopenic obesity was found in three (7.9%) participants. Nutritional status correlated with strength of lower extremities and physical performance tests (gait speed, Timed Up and Go Test and Short Physical performance battery). Higher number of steps per day positively correlates with physical performance.
Discussion: Interestingly, we did not find any correlation between the main obesity parameter such as percent body fat or body mass index (and thus sarcopenic obesity) and any of the selected behavioral factors (physical activity, sedentary behavior, or dietary habits). In conclusion, reaching the recommended levels of physical activity in older adults may not be sufficient to prevent the occurrence of obesity and sarcopenic obesity.
