Purpose In spite of the importance of food intake in weight management and preventing chronic diseases, it remains difficult to predict how anxious people change their eating behaviour in exposure to bad or good moods. The purpose of the study was to investigate the interaction effect of anxiety and different moods on food intake and blood pressure in healthy women students. Design/methodology/approach A total of 82 women university students (18-30 years) participated in the study. Subjects completed a valid anxiety questionnaire at baseline to measure trait and state anxiety scores, then they were randomly divided into two groups to watch comedy and drama movies for mood induction. After watching, some snacks were presented, and then energy intake and blood pressure were measured. Findings Students who suffered from severe state anxiety, consumed more energy from food when they watched a dramatic movie (p = 0.014). Subjects who suffered from moderate level of state anxiety and watched a dramatic movie experienced more systolic and diastolic blood pressure compared with subjects who suffered from moderate state anxiety but watched the comedy (p = 0.043 and p = 0.041, for systolic and diastolic blood pressure respectively). More diastolic blood pressure was shown among students who watched the drama movie and suffered from a severe level of trait anxiety (p = 0.049). Research limitations/implications Electrocardiography and stroke volume measurement were not used. Originality/value Our findings showed blood pressure elevation in anxious people when they experienced bad feeling such as sadness, and they also consumed more energy from food. Both of these factors are related to the occurrence of chronic disorders such as cardiovascular diseases.

Purpose Wrist-cuff oscillometric blood pressure monitors are very popular in the portable medical device market. However, its accuracy has always been controversial. In addition to the oscillatory pressure pulse wave, the finger photoplethysmography (PPG) can provide information on blood pressure changes. A blood pressure measurement system integrating the information of pressure pulse wave and the finger PPG may improve measurement accuracy. Additionally, a neural network can synthesize the information of different types of signals and approximate the complex nonlinear relationship between inputs and outputs. The purpose of this study is to verify the hypothesis that a wrist-cuff device using a neural network for blood pressure estimation from both the oscillatory pressure pulse wave and PPG signal may improve the accuracy. Design/methodology/approach A PPG sensor was integrated into a wrist blood pressure monitor, so the finger PPG and the oscillatory pressure wave could be detected at the same time during the measurement. After the peak detection, curves were fitted to the data of pressure pulse amplitude and PPG pulse amplitude versus time. A genetic algorithm-back propagation neural network was constructed. Parameters of the curves were inputted into the neural network, the outputs of which were the measurement values of blood pressure. Blood pressure measurements of 145 subjects were obtained using a mercury sphygmomanometer, the developed device with the neural network algorithm and an Omron HEM-6111 blood pressure monitor for comparison. Findings For the systolic blood pressure (SBP), the difference between the proposed device and the mercury sphygmomanometer is 0.0062 ± 2.55 mmHg (mean ± SD) and the difference between the Omron device and the mercury sphygmomanometer is 1.13 ± 9.48 mmHg. The difference in diastolic blood pressure between the mercury sphygmomanometer and the proposed device was 0.28 ± 2.99 mmHg. The difference in diastolic blood pressure between the mercury sphygmomanometer and Omron HEM-6111 was −3.37 ± 7.53 mmHg. Originality/value Although the difference in the SBP error between the proposed device and Omron HEM-6111 was not remarkable, there was a significant difference between the proposed device and Omron HEM-6111 in the diastolic blood pressure error. The developed device showed an improved performance. This study was an attempt to enhance the accuracy of wrist-cuff oscillometric blood pressure monitors by using the finger PPG and the neural network. The hardware framework constructed in this study can improve the conventional wrist oscillometric sphygmomanometer and may be used for continuous measurement of blood pressure.

Hypertension is one of the major risk factors associated with cardiovascular diseases. In this study, we will assess the frequency of hypertension among healthy university students and its association with gender, body mass index, smoking, and family history of both hypertension and cardiovascular diseases. We screened healthy university students ranging from 18 to 26 years of age. For each participant, we performed blood pressure measurements using a previously validated device and obtained demographic data, body mass index (BMI), smoking status, and family history of both hypertension and cardiovascular diseases. Out of the total number of 505 participants included in this study, 35.2% have blood pressure between 130/80 and 139/89, and 13.5% have blood pressure of more than 140/90. We found significant gender differences in both systolic pressure (p = 0.003) with mean difference = 18.08 mmHg (CI: 16.13 to 19.9) and diastolic pressure (p = 0.011) with mean difference = 3.6 mmHg (CI: 2.06 to 5.14), higher in males than in females. Upon comparing the mean difference in both systolic and diastolic blood pressure with BMI, we found significant differences in both systolic (p < 0.001) and diastolic (p = 0.002) blood pressure. We also found that smokers have significantly (p = 0.025) higher systolic blood pressure (mean difference = 4.2 mmHg, CI: 3.2 mmHg to 8.8 mmHg), but no significant difference for diastolic blood pressure (p = 0.386), compared to nonsmokers. First-degree family history of both hypertension and cardiovascular diseases affected systolic but not diastolic blood pressure. Taking into account the adverse short- and long-term effect of hypertension, we recommend adopting an awareness program highlighting the importance of screening blood pressure in young adolescent populations, keeping in mind that both high BMI and smoking are important modifiable factors.

Background Elevated blood pressure has been identified as a silent killer contributing to mortality and morbidity worldwide, hence it is essential to identify the high risk individuals at an early age to prevent the progress of the disease and its co-morbid conditions. Objective The objective of the present cross-sectional study was to assess the pattern of blood pressure distribution among students of medical and allied health professions at Gulf Medical University (GMU) Ajman, United Arab Emirates (UAE). Methods The study was conducted from November 2009 to February 2010. GMU has academic programmes such as Bachelor of Medicine, Physical therapy, Pharm D and Dental Medicine with a multiethnic student population. A pretested structured instrument used for data collection and blood pressure was measured using mercury sphygmomanometer. Descriptive statistics such as means and standard deviation were used to summarize the quantitative variables. The association of age, gender and nationality with systolic and diastolic blood pressure was determined by Pearson's correlation coefficient and a p-value ≤ 0.05 was considered statistically significant. Results The systolic and diastolic blood pressures were evenly distributed across all students irrespective of their age. A significantly higher systolic blood pressure in males was observed when compared to females, but the difference was not significant in diastolic blood pressure. In the present study among medical and allied health science students, the distribution of blood pressure was not associated with age. The mean systolic blood pressure and diastolic blood pressure were seen to be higher among Arabs when compared to Non-Arabs though not statistically significant. Family history of metabolic diseases did not show any association with the mean blood pressure. Conclusion There was a strong association for developing hypertension among male when compared to female gender. Key Words: University students; Age; Gender; Nationality; Systolic blood pressure; Diastolic blood pressureDOI: http://dx.doi.org/10.3126/nje.v1i3.5572 Nepal Journal of Epidemiology 2011;1(3) 86-89

Objective – to analyze the association of risk factors with the 1666 A>C polymorphism of the AGTR1 gene in patients with essential hypertension.Material and methods. 100 patients were screened, 72 of whom were genotyped. The control group consisted of 48 healthy individuals who did not differ in gender and age, and with the group of patients.Results. The obtained data confirmed that the level of blood pressure elevation is associated, to some extent, with modified (diabetes mellitus 2, smoking, body mass index) and unmodified factors (family history, gender) the risk of essential hypertension. The results of the analysis of blood pressure levels considering the A1166C polymorphism of the AGTR1 gene showed that the values of systolic and diastolic blood pressure in the group of patients with C-allele carriers were higher than in carriers of AA genotype: SBP – by 5.38% (p<0.05), DBP – by 5.15% (p<0.05). Conclusions. The level of blood pressure in patients with essential hypertension depends on body mass index and smoking. In carriers of the C-allele of the AGTR1 gene (A1166C), the level of systolic and diastolic blood pressure exceeds the ones of the carriers of the AA genotype. The presence of the C-allele of the AGTR1 gene (A1166C) almost doubles the risk of severe essential hypertension [OR = 2.75; p = 0.037].

Purpose Aeromedical training is meant to train aircrew in combating physiological problems that they might face in flight. Given the importance of the training, there are limited studies in the literature investigating the anxiety levels during aeromedical training along with training outcomes. This study aims to assess the untrained participants’ anxiety levels before and after aeromedical training, investigate the differences in anxiety levels across different physiological training devices and determine whether participants’ anxiety levels affect their G tolerances. Design/methodology/approach This study was carried out on 61 healthy male subjects (n = 61) who had applied for initial aeromedical training. Anxiety surveys and visual analog scales were administered before and after the practical aeromedical training. In addition, blood pressure and heart rate measurements were carried out. Findings Participants had significantly higher anxiety levels before human centrifuge training (pre-Glab) than before the altitude chamber training (pre-hypobaric). Participants who experienced G-induced loss of consciousness (G-LOC) had slightly more anxiety reported than the non-G-LOC group. There was a significant decrease between pre-Glab and post-Glab (after the human centrifuge training) and between pre-hypobaric and post-hypobaric (after the altitude chamber training) anxiety levels. The incidence of G-LOC was lower in participants having higher pre-G-Lab blood pressure. However, the difference in anxiety levels between the G-LOC group and the non-G-LOC group was not statistically significant. Research limitations/implications In this study, state anxiety inventory was not performed after human centrifuge training as centrifuge training lasted for around 5 min only, and it is not advisable to repeat state anxiety inventory in such short periods. Blood pressure was not measured after G-Lab training because human centrifuge training is hard training and has an impact on blood pressure. Hence, it would have been difficult to distinguish whether the blood pressure change was due to anxiety or hard physical activity. These limitations, especially for the G-Lab, caused us to evaluate state anxiety only with VAS. It would be worthwhile to repeat similar studies with objective measurements before and after the training. Practical implications This information suggests that instructors who train the applicants on aerospace medicine be ready for the possible consequences of anxiety. Originality/value There are only a few centers in the world that include all the physiological training devices (practical aeromedical training laboratories) together. To the best of authors’ knowledge, there are no studies in the literature investigating the differences in anxiety levels across various physiological training devices. The studies about the effect of anxiety levels on aeromedical training outcomes and anxiety levels before and after the training are scant.

It is pointed out in many articles that induced hypertension and gestational diabetes are well linked to pregnancy, but this relationship is not well determined. The report focuses on the pregnancy’s relationship with diabetes and induced hypertension. It is found herein that mean pregnancy is directly related with glucose levels (GLUC) (P=0.07), age (P<0.01), BMI (P=0.07), Diabetic Women (DW) status (P=0.01), interaction effect of Triceps SkinFold Thickness (TSFT) and age (TSFT × Age) (P<0.01), while it is inversely related with GLUC × Age (P=0.02), TSFT × BMI (P<0.01), Insulin (INSU) (P=0.06) and Diabetes Pedigree Function (DPDF) (P=0.03). Variance of pregnancy is directly related with GLUC (P=0.07), Diastolic Blood Pressure (DBP) (P=0.04), GLUC × TSFT (P<0.01), DBP × TSFT (P<0.01), DPDF (P=0.01), INSU × BMI (P=0.15), while it is inversely related with GLUC × DBP (P=0.01), TSFT (P<0.01), TSFT × DPDF (P=0.03), INSU (P=0.07). It is easily interpreted that pregnancy’s mean is well connected to diabetic parameters such as INSU and GLUC levels, history of DW, DPDF, BMI, GLUC × Age, while its variance is connected to diabetic and hypertension parameters such as GLUC, DPDF, DBP, GLUC × TSFT, DBP × TSFT, INSU × BMI, GLUC × DBP, TSFT × DPDF, INSU. Moreover, it is derived that a diabetic female has a higher chance to be pregnant than a normal woman.

AbstractEating out of home (OH) is increasingly popular in Balkan countries, among them Albania. To date there is only anecdotal evidence regarding nutritional quality of food consumed OH and the contribution to diet. This study assessed intake of foods and drinks consumed OH and at home (AH), as well as their nutritional contribution to the daily diet of university students in Tirana, Albania. Using a single day Automated Multiple Pass Method (AMPM) 24-hour dietary recall, we examined food intake among 289 students aged 18-24 years old, from three major universities in Albania. Contribution of eating OH to total energy intake per day, as well as to daily consumption of macronutrients by eating OH intensity tertiles were assessed. Foods and drinks consumed OH contributed 46.9% [95%CI:41.4-52.8] of total daily energy intake, representing, on average, 1169.1kcal [95%CI:1088.3-1249.9]. Sweets, soft drinks and meat products were more frequently consumed OH, while fruits and vegetables consumption was extremely low. The average quantity of sugars and dietary fats per day was higher AH, 76.9g [95%CI:70.3-83.5] and 173.7g [95%CI:163.2-184.2] respectively, compared to OH, 33.7g [95%CI:30.4-37.0] and 142.0g [95%CI:131.5-152.5] respectively. Dietary composition of AH intake was richer in sugars, total fats and proteins, while OH intake was richer in saturated fats. The overall diet appeared unhealthy, when nutrients were assessed as energy percentage against WHO proposed nutrient standards for sugar and saturated fats. Eating OH, even though was associated with lower fruits and vegetables intake, was not clearly associated with poor diet quality, as AH foods were also characterized by increased saturated fats and sugars intake as energy percentage. This study provides data on the first assessment of current dietary patterns of the studied population and can be used as baseline for designing and conducting future studies and interventions targeting malnutrition in all its forms.
