Arsenic (As), copper (Cu), zinc (Zn) and selenium (Se) in northwest Croatian seafood: A health risks assessment.

This study focuses on the health risk assessment of arsenic (As), copper (Cu), zinc (Zn), and selenium (Se) concentrations in seafood species commonly consumed in the northwestern region of Croatia. By measuring the concentrations of these elements coupled with data on seafood consumption, the health risks were evaluated using Target Hazard Quotients and Hazard Indexes. The results indicate a slightly increased health risks linked to seafood consumption for As, Cu and Zn in some of the tested seafood species. The findings of this study highlight the critical need for stronger food quality control measures, especially targeting certain types of seafood.

Implementation of program of prevention and early detection of osteoporosis among women of Primorsko-goranska County.

The aim of this paper is to present preliminary data of Program of prevention and early detection of osteoporosis among women in Primorsko-goranska County. Osteoporosis is recognized as a public health problem for which clearly preventive measures are defined. Measurement of bone density was done by ultrasound densitometry of the calcaneus among women aged from 45 to 69 years old. 688 women were examined and they were classified in five five-year age groups. The women with the osteoporosis (T-score < or = 2.5) were 141; osteopenia (T-score from -2.5 to -1) were found in 400 women, and those with normal range of T-score were 147. All of five groups of women had T-score in range of osteopenia (T-score < or = 1). A statistically significant difference was between the first and fourth groups of women (p = 0.002) and the second and fourth groups (p = 0.001). After examination, depending on the value of T-score, women were recommended to visit family doctor and they also got educative booklet with advices for healthy nutrition and physical activity. Implementation of this program indicated the importance of proper lifestyle in the prevention of osteoporosis. Average T-scores of all five groups of women show that osteopenia occurs also in the youngest ones. This indicates the need for a systematic approach to preventing osteoporosis through education of women including younger ones and creating conditions for organized physical activities at the community level.

Cancer and cardiovascular diseases nutrition knowledge and dietary intake of medical students.

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.

Diet quality of middle age and older women from Primorsko-Goranska County evaluated by healthy eating index and association with body mass index.

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.

Prevalence, Knowledge and Attitudes Concerning Dietary Supplements among a Student Population in Croatia.

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.

Daily menus can result in suboptimal nutrient intakes, especially calcium, of adolescents living in dormitories.

The aims of this study were to evaluate daily menus in Croatian dormitories and to assess the overall intake of dairy products among resident adolescents. For this purpose, 168 daily menus were chosen for nutritional evaluation by random sampling. In addition, 227 adolescents (133 girls and 94 boys) participated in a questionnaire focused on food intake in addition to the meals supplied in dormitories with the aim to assess the amount and the type of dairy products consumed. The results showed that only 35% of the daily menus were nutritionally balanced. Most of the menus provided an excess of energy, protein, carbohydrate, saturated fat, phosphorus, riboflavin, and vitamin A. The levels of calcium and magnesium in the menus were suboptimal. The menus offered to adolescents provided approximately 2 servings of dairy products per day. Milk was the most often supplied dairy product (1.1 servings per day), whereas yogurt had the lowest frequency of serving (0.2 servings per day). The most preferred dairy-based snack for both sexes was milk. Dairy-based snacks provided about 1 serving per day for both sexes and contributed to about 30% of the recommended dietary allowances for calcium. Adolescents who regularly consumed dairy-based snacks meet the recommendations (3.2 servings of dairy products per day and about 98% recommended dietary allowances for calcium). We conclude that the institutional menu planning should be improved because the intake of dairy snacks will continue to be a problem for achieving a healthy diet in adolescences.
