Prior research shows that work on board vessels of the Royal Norwegian Navy (RNoN) is associated with noise exposure levels above recommended standards. Further, has been found to impair cognitive performance in environmental, occupational, and experimental settings, although prior naval maritime settings sparse. The aim this study was evaluate after among personnel working RNoN. Altogether 87 (80 men, 7 women; 31 ± 9 years) from 24 RNoN were included. Noise recorded by personal dosimeters...

Abstract Background The skin microbiota maintains a physical and immunological barrier to the environment. Little is known about how microbiome changes over time or effect of hand hygiene practices moisturizer use. Objectives To assess sex‐specific in bacteria time, related self‐reported eczema, use moisturizers. Methods Swab samples from dorsal were collected at baseline 6.5 years later during COVID‐19 pandemic, 168 participants RHINESSA study Bergen, Norway. analysed by 16S rRNA amplicon...

Prior studies have indicated a high prevalence of noise-induced hearing loss (NIHL) among Navy personnel; however, it is not clear whether this caused by work on board. The present study aimed to assess the personnel in Royal Norwegian (RNoN), and investigate there an association between board RNoN vessels occurrence loss.Navy currently working were recruited complete questionnaire noise exposure health followed pure tone audiometry. Hearing was defined as threshold levels ≥25 dB either ear...

Despite awareness of noise aboard vessels at sea, few studies have reported measured levels ships. This study aimed to describe the in Royal Norwegian Navy (RNoN), and assess exposure personnel RNoN vessels. In 2012/2013 measurements were conducted 14 from four different vessel classes (frigates, coastal corvettes, mine vessels, coast guard vessels) which included this study. Mean median A-weighted (Lp,A) decibel (dB(A)) calculated for locations each class. The was assessed by dosimeter...

The COVID-19 pandemic has resulted in increased attention on infection prevention measures. This study aims to assess whether changes hand hygiene procedures, use of personal protective equipment and moisturizers during the first year were associated with occurrence skin symptoms among healthcare workers, cleaners, day-care workers. A total 602 participants (40%) responded an electronic questionnaire, including questions previous current occupational exposure problems. Increased frequency...

The aims of this longitudinal study were to investigate a significant threshold shift (STS) among personnel working on board the Royal Norwegian Navy's (RNoN) vessels between 2012 and 2014 identify possible determinants STS. Hearing thresholds measured by pure tone audiometry in two consecutive examinations (n = 226). STS was defined as an average change hearing ≥ + 10 dB at 2,000 Hz, 3,000 4,000 Hz either ear. Determinants assessed through questionnaire. incidence 23.0%. Significant number...

<h3>Objectives</h3> In a questionnaire conducted by The Royal Norwegian Navy in 2002/2003, 38% of the personnel reported to be much/very much exposed noise and 24% reduced hearing. Based on these findings, further investigation working conditions board naval vessels mapping NIHL among was initiated. A part this study is compare levels occurrence hearing loss large like frigates smaller coastal corvettes. <h3>Methods</h3> Noise areas were measured three costal corvettes (CC) (F) using Brüel...

Sir, In his letter to the Editor (1), Monasta is surprised that we, in our analysis of macrosomia as a cause adverse pregnancy outcome (2), ignored maternal height an additional determinant. However, this was not case. Unfortunately, item personal data notified Medical Birth Registry Norway. Thus, including feasible. Certainly, we acknowledge relevance variable perinatal epidemiology, and anthropometric measures will be included forthcoming notification scheme implemented by Still, might...
