The proposed criteria for high perceived misophonia in young healthy adults and the association between Misophonia symptoms and noise sensitivity.

Context: The association between noise sensitivity and misophonia has not been explored in any population, according to the available literature. Aims: To assess the proportion of misophonia symptoms among young healthy adults, to propose the criteria for high perceived misophonia, and to explore the association between misophonia with noise sensitivity with adjustment for sex, age, perceived anxiety, and depression. Settings and Design: A cross-sectional study on 1132 medical students, aged 21.4 ± 2.1 years. Methods and Material: Misophonia symptoms were self-reported using the Amsterdam Misophonia Scale. Nine criteria for high perceived misophonia are proposed. Noise sensitivity was measured with Weinstein scale. Perceived anxiety and depression were measured using the Hamilton Anxiety Rating Scale and the Hamilton Depression Rating Scale, respectively. Statistical Analysis Used: Multiple logistic regression. Results: Almost half of the students reported the feeling of irritation against people making provoking sounds. Only one in 10 claimed the feeling of loss of self-control when exposed to provoking sounds. High noise sensitivity and high depression were associated with higher odds of meeting the criteria for high perceived misophonia. Conclusion: Noise-sensitive students are at higher risk of reporting misophonia symptoms and of being classified with high perceived misophonia. The combination of at least four or more symptoms, which classifies every 10th student with high perceived misophonia, is proposed as a self-assessment tool for epidemiological studies among young healthy adults.

Nutrition labelling of pre-packaged foods in Belgrade, Serbia: current situation.

OBJECTIVE: To determine the presence of nutrition labels on pre-packaged food products, as well as to analyse the types of presentation. DESIGN: This was a descriptive study. The following characteristics were analysed: (i) presence and placement of the nutrition declaration (either as front-of-pack (FOP) or back-of-pack (BOP)); (ii) content of the presented information; (iii) presence of nutrition and health claims; and (iv) legibility of the written information. Settings Three different types of retailers in Belgrade, Serbia. SUBJECTS: A total of 2138 pre-packaged food products from ten categories. RESULTS: A nutrition declaration was found on 65.9% of all tested products. It was displayed on the back of the packaging of 62.7% of products and on the front of the packaging of 19.1% of products. BOP was the most commonly observed in breakfast cereals, soft drinks, milk and instant soups (in total over 90%), and the least common in meat products (21.5%). FOP was predominantly displayed on breakfast cereals (65.0%) and the least frequently on milk products (2.4%). The 'Big 4' (energy value, protein, carbohydrate and fat contents) and the 'Big 4 with additional information' figured on 40.9% of products. The 'Big 8' ('Big 4' plus sugar, saturated fat, fibre and sodium contents) and the 'Big 8 with additional information' were present less frequently (20.5%). Nutrition claims and health claims appeared on very few products (6.6% and 6.3%, respectively). The proportion of products with insufficient legibility was 31.5%. CONCLUSIONS: Nutrition labelling in Belgrade, Serbia is not satisfactory. Mandatory regulations may be the best way to improve the current situation.

Nighttime road-traffic noise and arterial hypertension in an urban population.

Commonly used daytime measurements in previous investigations on community noise and arterial hypertension (AH) may be a source of exposure bias, as urban residents spend most of their daytime hours out of the home on workdays. For this reason, we focused on the relation of nighttime noise and AH. A cross-sectional study was performed on a sample of 2,503 (995 men and 1,508 women) adult residents of a downtown Belgrade municipality. The inclusion criteria were a period of residence longer than 10 years and a bedroom oriented toward the street. The exclusion criteria were a high level of noise annoyance at work and diseases related to AH. Noise measurements were performed in all 70 streets of the municipality. The streets were grouped into noisy areas (equivalent noise level [Leq]>45 dB(A)) and quiet areas (Leq< or =45 dB(A)). The residents were interviewed in regard to antihypertensive therapy. Subjects who responded that they had not received such therapy were contacted for blood pressure measurements with mercury sphygmomanometer. Possible confounding factors: family history of AH, age, body mass index, smoking habits, physical activity and alcohol consumption were controlled for. The proportions of men with AH in the noisy and quiet areas were 23.6% and 17.5%, respectively. The adjusted odds ratio (OR) for AH was 1.58; the 95% confidence interval (CI) ranged from 1.03-2.42; and the probability value was 0.038, when men living in quiet streets were taken as a reference category. This relation was statistically insignificant for women: adjusted OR: 0.90; 95% CI: 0.59-1.38; p: 0.644. This cross-sectional study showed that nighttime urban road-traffic noise might be related to occurrence of AH in men.
