Electrodermal Activity: Simultaneous Recordings

Electrodermal activity (EDA) is a sensitive measure of the sympathetic nervous system activity. It is used to describe changes in the skin electrical properties. This chapter aimed to show advantages of simultaneous recordings of EDA parameters at the same skin site over other recordings. The literature databases, Web of Science and Google Scholar, were searched using terms like “electrodermal activity,” “sequential recording,” “simultaneous recording,” “skin conductance,” “skin potential,” and “skin susceptance.” Articles that include sequential and/or simultaneous recording of EDA parameters were analyzed. The chapter presents a description of the oldest and current methods used for recording EDA parameters and an explanation of the newest techniques used in EDA researches. Although sequential recordings are predominant and widely spreading, much effort has been made to simultaneously record skin conductance (SC) and skin potential (SP), and recently researchers realized the capability of simultaneously recording SC, SP, and skin susceptance (SS) at the same skin site. The advantage of simultaneous over the sequence measurements is that the latter must be manually time realigned when measured by different instruments, which means it is time-consuming. Although the simultaneous measurements are used exclusively for research purposes at this stage, this may open horizons in the modern trends of psychophysiology applications in the near future

Bioelectrical impedance method for assessing later body-composition considering the influence of breastfed on gender

Purpose: to study the effect of breastfeeding on body composition in both male and female via bioimpedance analysis method. analysis methods. Methods: we determined the body composition (body fat percentage, muscle mass percentage, and bone mass percentage) by bioimpedance analysis methods in 60 adults (31 male and 29 female) who were classified as underweight, normal and overweight subjects aged 20 years old. Average BMI was 21.4 Kg/ m2 which calculated by traditional formula. Findings: The differences in %BF assessed using bipolar analyzers were significantly higher for female than male. There was a significant difference (

Assessment of Food Safety Knowledge, Attitudes and its Quality in Student Canteens at Duhok University, 2015

Maintaining and improving the health level of college students are important aspects for higher education, where the food security becomes the foundation of the health. The aim of this study was to assess the level of knowledge and attitudes about food safety and to evaluate the quality of food (Physical & Operational Standards) in the student canteen at Duhok University. To achieve this goal, three questionnaires were developed. Concerning food safety knowledge and attitude for food handles (buying, storage and serving food) data was collected using these self-questionnaires. The study was conducted on (319) respondents. The obtained data were analyzed and statistically tested. The results have shown that neither age nor education levels have significant impact on the food safety knowledge. However, significant difference between male and female was found for the age >41. For food quality evaluation, the results have also shown that canteen workers lack the physical and operational standards of food safety especially taste and healthy ways of food prepared. The analysis has shown that the positive attitudes of canteen owner toward food handlers were 66.25% for buying, 31.2% for storage and 42.5% for serving food. The overall positive attitude was 46.65% which is insufficient range. Overall respondents had poor food safety knowledge. There was a significant difference between the mean score of knowledge according to gender for group >41 years. In male only, the age has to impact on safety knowledge. While educational levels had no significant impact. The untrained employees who manage the university canteen made their attitudes toward storage and serving food unwelcome

Regional body fat distribution assessment by bioelectrical impedance analysis and its correlation with anthropometric indices

Objective: The purpose of this study is to assess the validity of Bioelectrical Impedance Analysis (BIA) to characterize the regional fat distribution among female and its correlation with anthropometric indices. Materials and methods: The following indices were carried out: weight, height, body mass index (BMI), waist circumference (WC), hip circumference (HC), waist hip index (WC + HC) of random samples (209) of women (age, 32–85 years). The segmental body fat percentages were assessed by bioelectrical impedance analysis. Hand-to-Hand and Foot-to-Foot Body Analyzer devices were used to estimate upper and lower body fat percent (BF %), respectively. Upper and lower body fat measurements were used to calculate total body fat. Agreement between the variables was assessed by scatter plots. Results: The plots of upper and lower percent body fat (BF %) against waist and hip circumferences revealed significant correlation values of (r = 0.949) and (r = 0.942), respectively. The total of upper and lower body fat ratios showed a stronger correlation with the BMI than those of severally. Weak to fear correlations between upper and lower body fat percent, with BMI were observed. Conclusion: The results indicated that the BIA technique of estimating segmental body fat percent associated with the anthropometrical indices (WC, HC) has the potential to determine adiposity risk available for use in large epidemiological studies. Keywords: Bioelectrical impedance, Regional body fat, Women health, BMI, Anthropometric indice

Effects of The Long-Time Wearing of Gloves by Health Care Workers Managing Covid-19 Assessed by Electrodermal Activity: A Pilot Study

Continues wearing gloves is a crucial problem among health care workers treating patients with coronavirus (COVID-19) infection that may cause skin complications. In the present study, the skin conductance (SC), skin potential (SP) and skin susceptance (SS) were used to identify the effects of long-term wearing gloves among health care workers managing COVID-19. The experimental procedure was repeated 30 times on three subjects recruited as volunteers to wear gloves for 4 hours. The baseline of parameters SC, SP, and SS were recorded at normal conditions without wearing the glove at zero time (To). The parameters were again recorded in the cases of glove-wearing with and without zinc oxide ointment (ZnO) for the same period. Noticeable differences were found in each of SC, SP and SS for subjects who wore gloves when compared to the baseline for 4 h. Results also showed significant differences in each of SP and SS during the same period with applying ZnO comparing to wearing gloves without applying ZnO. The results show that skin hydration is significantly improved by using ZnO. However, changing gloves at least every four hours of continuous wearing is recommended
