Cardiac Autonomic Regulation

Airport activity causes the emission of particulate matter and noise, two environmental contaminants and potential health hazards, particularly for the personnel operating nearby taxiways. We explored the association between exposure to fine/ultrafine particles (UFPs) and noise with heart rate variability (HRV), an early indicator of cardiovascular autonomic response, among a sample of airport ground staff. Between May and June 2018, thirty-four male operators (mean age = 43 years and SD = 6.7) underwent personal monitoring of exposure to nanoparticles and noise, and HRV during their work activity. We conducted univariate and multivariate analysis to test the effect of UFP and noise exposure HRV. Total Lung Deposition Surface Area (LDSA) was significantly associated with a decrease in HRV Total Power and Triangular index (β = −0.038 p = 0.016 and β = −7.8 × 10−5, p = 0.042, respectively). Noise peak level showed an opposite effect, which was significant for Total Power (β = 153.03, p = 0.027), and for Triangular index (β = 0.362, p = 0.035). Further investigation is warranted to clarify the effect of the concurrent exposure to UFPs and noise on early changes of cardiac autonomic regulation.

Behavioural Aspects

Background - In recent years there has been a proliferation of alternative tobacco and nicotine products that reduce consumers’ exposure to harmful substances and therefore have the potential to reduce risk to health. Post-market surveillance enables the evaluation of newly introduced tobacco and nicotine products (aka potentially reduced risk products (PRRPs)) at a population level. This study aims to investigate tobacco and nicotine consumer demographics and discover how people are using these products, and characterise behavioral trends as transitions between tobacco heated products (THPs) and other nicotine products. These behavioural aspects, in conjunction with the intrinsic risk of the product, are essential for assessing the potential health effects and establishing a population risk assessment. Design and methods - This epidemiological cross-sectional study will collect data using a self-administered study instrument from the general Japanese population aged 20 years and older. The targeted sampling size is up to 5,000 participants per study wave. The study addresses the following objectives: estimation of tobacco and nicotine use prevalence; characterisation of  product usage by product type; changes in use behaviour in general, with particular emphasis on the introduction of THPs in the time period of one year; risk perceptions of different tobacco products and no tobacco usage; and participant perceived health status and quality of life. Discussion - The description of tobacco and nicotine product use behaviour, the estimation of prevalence data, the measuring of product-specific risk perception and the change of tobacco use behaviour within one year will allow for a comprehensive assessment of the effect of introducing THPs into a market. These data could also be used to inform a system dynamics population model in order to estimate the public health impact of introducing a THP into the Japanese market.

Abstract Background: Vitamin A is a fat-soluble vitamin essential for the proper functioning of the immune system. It fondes both animal and plant sources in the form of retinol from animal sources or beta-carotene from plant source foods. Due to increased nutrient need and the severity of the potential health consequences are associated with vitamin A deficiency (VAD), preschool children and pregnant women are considered as the most at risk segments of the community. Hence, this study aimed to assess the prevalence of VAD and associated factors among children aged 6-59 months in Dera woreda, Northwest Ethiopia. Methods: Community based quantitative cross-sectional study was conducted among children aged 6-59 months in Dera woreda from December 1/2018 to January 1/2019. Multistage random sampling was used to select the required samples (267). Data were coded and entered into Epi-data version 3.1 and exported to SPSS (Statistical Package for Social Sciences) version 20 for analysis. Binary logistic regression was fitted. Both bivariable and multivariable analyses were used to identify factors associated with VAD. Those variables that were showed significant association in multivariable association at P value less than 0.05 declared as statistically significant factors of VAD among children age 6-59 months. Results: Two hundred sixty seven mother-children Pairs were included in the study making a response rate of 94.7%. The overall prevalence of Vitamin A deficiency among children age 6-59 months was 7.8% (95% CI (4.7, 11.3). Antenatal care follow up (AOR: 0.446,95 % CI (0.155, 0.980)); birth interval within 2 year (AOR: 0.392, 95 % CI (0.107, 0.839)), and age group of24-35 months (AOR; 1.206, 95 % CI (1.037, 6.129)) were significantly associated with vitamin-A deficiency. Conclusion: The overall prevalence of vitamin A deficiency in this study was found to be lower than the national and regional prevalence. According to this study, VAD is a mild public health problem. Age of children, birth interval, ANC follow up, remain the most important associated factors for vitamin A deficiency. Therefore to decrease the prevalence of VAD, ANC service should be strengthened and we should focus on older children birth interval and age- based food needs.

Abstract Purpose Vitamin D, produced through cutaneous photosynthesis or ingested via foods or supplements, has generated considerable research interest due to its potential health effects. However, epidemiological data on the time trends of vitamin D status are sparse, especially from northern Europe. We examined the time trend of vitamin D concentrations in northern Sweden between 1986 and 2014. Methods We used data on 11,129 men and women (aged 25–74 years) from seven population-based surveys (the Northern Sweden MONICA study), recruited between 1986 and 2014. Serum vitamin D (25-hydroxyvitamin D) status was measured using a one-step immunoassay (Abbott Architect). Multivariable linear regression models, adjusted for age, sex, and a number of other variables, were used to estimate the time trend of vitamin D concentrations. Results The mean value of vitamin D in the entire study population was 19.9 ng/mL [standard deviation (SD) 7.9], with lower values in men (19.4 ng/mL; SD 7.5) than in women (20.5 ng/mL; SD 8.2). Using the survey in 1986 as reference category, the multivariable-adjusted mean difference [95% confidence interval (CI)] in ng/mL was 2.7 (2.2, 3.3) in 1990, 3.2 (2.7, 3.7) in 1994, 1.6 (1.0, 2.1) in 1999, − 2.0 (− 2.5, − 1.4) in 2004, 1.0 (0.4, 1.5) in 2009, and 3.1 (2.5, 3.6) in 2014. Conclusion In this large cross-sectional study, we observed no clear upward or downward trend of vitamin D concentrations in northern Sweden between 1986 and 2014.

Abstract Introduction Limited research exists about the possible cardiovascular effects of electronic nicotine delivery systems (ENDS). We therefore sought to compare exposure to known or potentially cardiotoxic volatile organic compounds (VOCs) in ENDS users, smokers, and dual users. Methods A total of 371 individuals from the Cardiovascular Injury due to Tobacco Use study, a cross-sectional study of healthy participants aged 21–45 years, were categorized as nonusers of tobacco (n = 87), sole ENDS users (n = 17), cigarette smokers (n = 237), and dual users (n = 30) based on 30-day self-reported tobacco product use patterns. Participants provided urine samples for VOC and nicotine metabolite measurement. We assessed associations between tobacco product use and VOC metabolite measures using multivariable-adjusted linear regression models. Results Mean (SD) age of the population was 32 (±6.8) years, 55% men. Mean urinary cotinine level in nonusers of tobacco was 2.6 ng/mg creatinine, whereas cotinine levels were similar across all tobacco product use categories (851.6–910.9 ng/mg creatinine). In multivariable-adjusted models, sole ENDS users had higher levels of metabolites of acrolein, acrylamide, acrylonitrile, and xylene compared with nonusers of tobacco, but lower levels of most VOC metabolites compared with cigarette smokers or dual users. In direct comparison of cigarettes smokers and dual users, we found lower levels of metabolites of styrene and xylene in dual users. Conclusion Although sole ENDS use may be associated with lower VOC exposure compared to cigarette smoking, further study is required to determine the potential health effects of the higher levels of certain reactive aldehydes, including acrolein, in ENDS users compared with nonusers of tobacco. Implications ENDS use in conjunction with other tobacco products may not significantly reduce exposure to VOC, but sole use does generally reduce some VOC exposure and warrants more in-depth studies.

Abstract The Ciclovia program (CP) has emerged as an effective initiative to promote active living in urban spaces in Latin America. This study assessed the association between social conditions, the urban environment and participation in the CP among adults living in the city of Cali, Colombia. A cross-sectional study was conducted in 2011 and 2012 among 719 adults aged 18 to 44. Urban environment measures were obtained using Geographic Information Systems. A multilevel logistic regression was used for the analysis. Slightly more than 7% of participants had participated in the CP in the previous four weekends. Being male and having a high school degree were positively associated with participation in the CP. Participation in the CP was positively associated with living in neighborhoods with Ciclovia lanes. In contrast, a negative association was found among those living in neighborhoods with a presence of traffic fatalities. This study provides new insights about a recreational program that has potential health benefits in a region marked by urban inequalities in terms of opportunities for physical activity.
