Objective: Present study aimed to assess potential health risk in Slovenian adolescents due to inadequate diet and/or dietary supplement (DS) use.

Methods: Data on DS use, micronutrient intake (24-h recall), eating habits (FFQ), body height and mass were collected within ACDSi (Analysis of Children's Development in Slovenia) cross-sectional study conducted in 2014. Adolescents enrolled in first year of 15 secondary schools (average (SD) age: 15.

Secular trends in body height have been proved indicative of socio-economic development of a country or a region, as well as of childhood and adolescent (mal)nutrition. Being taller has been associated with enhanced longevity, with several body height related factors involved. While basic anthropometric measurements, including body height, have long been performed in developed societies, primarily in men and children, far less data are available for adults and women in particular.

Due to their specific mode of operation, military personnel are challenged physically as well as mentally. In most countries, the use of food supplements by military personnel is not regulated, and a high prevalence of supplementation is expected. However, data on this are scarce or very limited, without insights into the importance of supplementation for the intake of bioactive substances.

Objective: Evaluate the adequacy of energy/macronutrient intake in adolescents according to the Slovenian national recommendations adopted from the recommendations of the German Nutrition Society and to identify differences in energy/macronutrient intake between differently active adolescents.

Methods: Data on energy and macronutrient intake (24-hour dietary recall), physical activity (SHAPES questionnaire), and anthropometric characteristics (body mass and height) of adolescents were obtained on a representative sample of first-year secondary school students (average (SD) age: 15.3 (0.

Objective: Several methods for the assessment of body composition exist, yet they yield different results. The present study aimed to assess the extent of these differences on a sample of young, healthy subjects. We hypothesised that differences in body composition results obtained with different methods will vary to the extent that a subject can be misclassified into different nutritional categories.

The methodology used in dietary surveys could, to a large extent, follow the instructions of the European Food Safety Authority (EFSA), where 24-h dietary recall (24HDR) is recommended for (sub) population studies. However, it is necessary to examine the suitability of 24HDR for indicative dietary intake in older adults. This study aimed to compare participants' dietary intakes with the recommendations and to compare dietary intakes derived from a 24HDR using an OPEN web-based application to those obtained from reference weighed food records (WFRs).

Body position affects body water distribution and in turn the accuracy of bioelectrical impedance analysis (BIA), which may consequently distort conclusions about an individual's body composition.We compared body fat percentage (BFP) obtained with leg-to-leg-BIA (LL) and hand-to-leg-BIA (HL) with the reference values.The BFPs of 97 individuals were determined with an LL- (Tanita TBF 215GS, Japan) and HL- (Akern, STA/BIA, Italy) BIA-analyser and with reference skinfold thickness (SF) measurements.

Aim: The present study examined body composition of students and aimed to evaluate their risk for obesity.

Methods: Height, body mass, body mass index (BMI), triceps skinfold, the percentage of body fat tissue as determined from triceps skinfold, and waist circumference were analysed in 286 20-year old subjects, born in the forties, sixties and eighties of the last century. Percentage of overweight was determined according to BMI, triceps skinfold, and waist circumference.
