RESUMEN
The aim of this study was to determine the prevalence of usage and the knowledge and attitudes towards dietary supplements among medical sciences and nonmedical sciences students from Croatia. The study was conducted based on a questionnaire about dietary supplement usage, knowledge and attitudes. The prevalence of dietary supplement use, among 910 university students was 30.5%. The most-used dietary supplements were vitamins (18.0% in medical sciences students and 9.8% in non-medical sciences students). For all students, the internet (66.1%) was the most common source of information, followed by healthcare professionals (33.2%). The most common reason for taking dietary supplements was to maintain good health (26.4%). Use of the internet rather than health professionals as a trusted information source should be revised among this young population. Supplement intake was significantly associated with body mass index (BMI) (p = 0.016) and physical activity (p = 0.050). Students with normal BMI (61.5%) and the most physically active students (37.7%) took significantly more dietary supplements. Results of this study could help medicine faculties to improve their curriculum and support the development of public health messages aimed at wise and safe use of dietary supplements.

The aims of this study were to determine medical students' knowledge regarding the association between dietary factors and the risk of cancer and cardiovascular diseases and to investigate if this knowledge has an impact on their dietary intakes. Three hundred and ninety medical students (males and females) were included in a study and grouped according to their daily fibre and fat intakes. For diet-disease knowledge, questions from the General Nutrition Knowledge Questionnaire for Adults were used and dietary assessment was done with Food Frequency Questionnaire. The obtained results showed that the students' diet-disease knowledge was generally inadequate. Higher level of diet-disease knowledge was among those with high dietary fibre intake, with slightly better scores for dietary factors and risk for cardiovascular diseases than the risk for cancer. Better diet-disease knowledge positively correlated with higher intake of fish (p = 0.027, p = 0.001) and vegetables (p = 0.019, p = 0.001) in high fibre groups of both gender, and in females additionally with fruit intake (p = 0.038, p = 0.007). A higher dietary fibre intake among studied students seems to be a factor that ensures lower obesity rates, lower intake of energy and lower consumption of coffee, sweets and alcoholic drinks. On the basis of the results of this study, it is clear that medical schools should provide in their nutrition programs the opportunity for students to learn about their own dietary and lifestyle behaviours, in order to more knowledgably and convincingly counsel their future patients.

Accorded dietary habits provide adequate nutrient intakes, especially important for quality aging. Adequate nutrition for older persons has vital influence on maintaining good health and social functioning. Therefore, using simple tool for evaluation of diet of older population in relation to overweight and obesity is of public health importance. Among many factor that influence quality of aging has obesity, where in Croatia the prevalence of obesity is greater in older women than men. Our aim was to evaluate diet quality of middle age and older women from Primorsko-Goranska County by Healthy Eating Index (HEI) and to see the association of HEI to overweight and obesity. Diet quality of 124 women with average age 59.91 +/- 5.31 years was graded with 10 component HEI score, ranging from 0 to 100, where HEI score less than 51 implies "poor" diet. Overweight and obesity was classified according to WHO classification. The majority of women had diet that "needs improvement" (66.1%), and only 3.2% had "good" diet. Older women had better HEI score than middle-aged women, while overweight was statistically significant positively related to better HEI score (P = 0.26, p = 0.048). Older women better scored for meat, dairy, cholesterol and dietary variety. "Poor" diet mostly had women with normal weight and middle-aged. Age did not influenced overall HEI score, neither its components. Obese women had lower achievements for almost all recommended HEI components. Women having "poor" diet quality could raise a chance for overweight and obesity for almost two times ([OR] = 1.67, 95% [CI] = 1.072-2.59, p = 0.023; [OR] = 1.51, 95% [CI] = 1.08-2.10, p = 0.015, respectively). The provided results showed that with age, women tended to have better diet. These could be because of that with aging are higher disease incidences that essentially need diet improvements; so older women tended to improve their diet to reduce disease discomforts. Being obese influenced the diet quality of our sample of women, therefore, for quality aging, the importance of public health nutrition programs are strongly needed. HEI score is a good assessment for diet quality, but further investigation of influence on other sociodemographic and health characteristics is required.
