Abstract Context Whole body vibration is a fairly new method with an incremental attention in the fields of sport and rehabilitation. It’s therapeutic and physiologic effects seems to be related to determined parameters like frequency, amplitude, and the position of the subject on the platform. One of the recommended items to be evaluated in studies involving whole body vibration is the skidding of feet. Few studies have reported the incidence of skidding so far. Objective To investigate the skidding occurrence in a group of healthy subjects with normal range of body mass index. Design Cross sectional study Setting Biomechanics lab of the School of Rehabilitation sciences, Shiraz University of Medical Sciences Participants Thirty healthy individuals with age range between 18 and 40 years and body mass index between 18.5 and 24.9 kg/m2 Intervention Twelve different conditions including three different frequencies (20, 30, and 45 Hz), high (3 mm) and low (1.5 mm) amplitudes, and two standing positions (erect and semi squat positions) were evaluated. Main outcome measure incidence of skidding Results The incidence percentage varied from 0 to 36%. The highest incidence rate pertained to a condition during which the frequency was 30 Hz, the amplitude was 3 mm, and the subject stood erect on the platform. The skidding did not occur in two of the conditions involving erect standing, frequency equal to 45 Hz, amplitude of 1.5 mm and semi-squat position, frequency equal 20 Hz, and amplitude of 1.5 mm. Conclusion It seems that different parameters such as standing position, selected amplitude, BMI, and frequency rather than a single factor might influence the incidence of skidding.

Urban Rail

Urban rail is a widely used public transportation; the vibration from frequent rides may impact passengers. The rail vehicle’s vibrations can cause human fatigue and result in severe musculoskeletal problems to the passenger. This paper aims to identify the effects of passenger orientation, operation time and body mass index on passengers’ whole-body vibration on an urban rail in Malaysia. Real-time monitoring of the whole-body vibration was conducted using 23 full factorial designs of the experiment, which was analysed statistically using Minitab Software. The overall result of this study is that the passengers in a seated position had greater exposure to whole-body vibration, which is 0.3686 ms-2 than standing passengers, 0.2965 ms-2. Also, passengers tend to be exposed to greater vibration during an off-peak time of 0.4063 ms-2, than a peak time of 0.3706 ms-2. Lastly, overweight passengers were exposed to greater vibration, of 0.4063 ms-2, than passengers within the ideal weight range of 0.4000 ms-2. This study has statistically proven that all the factors were significantly influenced the vibration exposure to the passenger. The most significant factor towards the vibration exposure is the “Body Mass Index (BMI)”, in which the p-value is less than 0.001. This study concludes that the whole-body vibration of a passenger is affected by the orientation of the passenger, operation time and body mass index of passengers on urban rail service.

<p><em>Low back pain is a common disease affecting almost all individuals at some point in their life. Low back pain is multifactorial in origin. The cause of increased prevalence of low back pain in populations of professional drivers is often uncertain. The factor reported to be most strongly associated with low back pain are exposure to whole body vibration. Other possible risk factors with weaker or inconsistenst evidence for influencing low back pain are individual factors (age, time of work, body mass index and physical activitity). This research is conducted observasionally with cross sectional design with a large sample of 70 people which selected by purposive sampling. Data collected from accelerometer, questionnaires, observation and interviews. The results of research obtained that exposure whole body vibration suffered by operator is 0,543 m/s<sup>2</sup> and complaints of low back pain on a heavy equipment operators at PT. X is 64,3 %. Bivariat analysis showed that there are significant relationship between whole body vibration (p&lt;0,05;95 % CI 0,99-2,99 OR 1,723), age (p&lt;0,05; 95 % CI 1,42-3,77 OR 2,31), time of work (p&lt;0,05; 95 % CI 1,07-7,81 OR 2,89) with low back pain. There was no significant relationship between body mass index (p&gt;0,05; 95 % CI 0,68-1,37 OR 0,969) and physical activity (p&gt;0,05; 95 % CI 0,55-1,14 OR 0,798) to low back pain. This research conclude that there is correlation whole body vibration with complaints of low back pain. </em></p><p><strong>Keyword:  </strong><em>whole body vibration, low back pain, operator</em></p>

Hipertensiadalah penyebab kematian utama di Indonesia. Kematian akibat hipertensi lebih banyak terjadi di perkotaan dibandingkan di desa. Tingginya kejadian hipertensi dipengaruhi oleh faktor yang dapat dikontrol (obesitas,berat badan lebih, konsumsi garam berlebih,aktivitas fisik rendah, perokok, dan konsumsi alkohol) dan faktor yang tidak dapat dikontrol (genetik, usia, dan jenis kelamin). Penelitian bertujuan memberikan gambarandistribusi tekanan darah dan indeks massa tubuh (IMT) pendudukperempuan di kota maupun di desa.Desain penelitian adalah deskriptif kuatitatif dengan pendekatan cross sectional. Data primer didapatkan melalui pengukuran tekanan darah, tinggi badan dan berat badan. Penelitian dilakukan di Desa Kutowinangun Kidul, Kecamatan Tingkir,Salatiga yang mewakili penduduk perempuan di perkotaan dan Desa Batur, Kecamatan Getasan, Kabupaten Semarangyang mewakili penduduk perempuan pedesaan. Adapun jumlah sampel masing-masing 66 respondendan 72responden. Hasil penelitian menunjukkan bahwa kejadian penyakit hipertensi, resiko obese dan obese lebih didominasi oleh respondendi perkotaan dibandingkan di pedesaan dengan rentang usia di atas 46 tahun. Respondendi desa dengan indeks massa tubuh normal cenderung mengalami pre-hipertensi (8,3%) dan hipertensi stadium I (6,9%) sementararesponden dengan resiko obese dan obese cenderung mengalami hipertensi stadium I (1,4%).Respondendi kota dengan indeks massa tubuh normal cenderung mengalami pre hipertensi (6,06%), hipertensi stadium I (4,5%) dan II (7,5%). Responden dengan resiko obese cenderung mengalami hipertensi stadium I (4,5%), dan responden dengan obese I dan II cenderung mengalami pre-hipertensi (4,5%).   Hypertension is the leading cause of death in Indonesia. Deaths due to hypertension are more common in urban areas than in villages. The high incidence of hypertension is influenced by factors that can be controlled (obesity, overweight, excessive salt consumption, low physical activity, smokers, and alcohol consumption) and factors that cannot be controlled (genetic, age, and sex). The study aimed to provide an overview of blood pressure distribution and body mass index (BMI) of female residents in cities and villages. The study design was descriptive quantitative with a cross sectional approach. Primary data was obtained through measurements of blood pressure, height and weight. The study was conducted in Kutowinangun Kidul Village, Tingkir Subdistrict, Salatiga representing women in urban areas and Batur Village, Getasan Subdistrict, Semarang Regency, representing rural women. The number of samples was 66 respondents and 72 respondents respectively. The results showed that the incidence of hypertension, the risk of obese and obese was more dominated by respondents in urban areas than in rural areas with ages above 46 years. Respondents in villages with normal body mass index tended to experience pre-hypertension (8.3%) and stage I hypertension (6.9%) while respondents with obese and obese risk tended to experience stage I hypertension (1.4%). Respondents in cities with normal body mass index tended to experience pre-hypertension (6.06%), stage I hypertension (4.5%) and II (7.5%). Respondents with obese risk tended to experience stage I hypertension (4.5%), and respondents with obese I and II tended to experience pre-hypertension (4.5%).

Abstract Background A significant relationship has been documented in the literature between the autonomic nervous system imbalance and cardiovascular mortality. In patients with autonomic failure, water ingestion has been shown to increase blood pressure (BP), induce bradycardia, and cause low heart rate variability (HRV). A few studies showed the altered HRV as an acute effect of ice water intake in healthy subjects. None of the studies have shown light on the relationship of BP and HRV to ice water intake in obese and overweight subjects. The present study is aimed to correlate BP and HRV with body mass index (BMI) after ice water ingestion. Methods This cross-sectional study included a total of 60 subjects of both sexes aged between 18 and 24 years old. Subjects were assigned into three groups based on their BMI: normal, overweight, and obese. Before and after ice water ingestion, BP and HRV parameters were recorded and compared between the groups. Statistically data were analyzed by Student’s paired t-test and one-way analysis of variance. Results Basal HF was significant (p<0.05) in all three groups after ice water ingestion [F(2, 27), 44.1; p-value, 0.02]. After ice water ingestion, all HRV values were significant (p<0.001) in the three groups. The post-hoc Tukey HSD test demonstrated the less mean score for mean RR interval, standard deviation of all NN interval, standard deviation of differences between adjacent, HF and high for HR, LF, and LHR in overweight and obese subjects. Conclusions Because of the effective buffering system, healthy subjects showed increased HR and unchanged BP. Overweight and obese subjects showed decreased HR and increased BP.

A single abdominal cross-sectional computerized axial tomography and magnetic resonance image is often obtained in studies examining adipose tissue (AT) distribution. An abdominal image might also provide additional useful information on total body skeletal muscle (SM) and AT volumes with related physiological insights. We therefore investigated the relationships between abdominal SM and AT areas from single images and total body component volumes in a large and diverse sample of healthy adult subjects. Total body SM and AT volumes were derived by whole body multislice magnetic resonance imaging in 123 men [age (mean ± SD) of 41.6 ± 15.8 yr; body mass index of 25.9 ± 3.4 kg/m2] and 205 women (age of 47.8 ± 18.7 yr; body mass index of 26.7 ± 5.6 kg/m2). Single abdominal SM and AT slice areas were highly correlated with total body SM ( r = 0.71–0.92; r = 0.90 at L4–L5 intervertebral space) and AT ( r = 0.84–0.96; r = 0.94 at L4–L5 intervertebral space) volumes, respectively. R2 increased by only 5.7–6.1% for SM and 2.7–4.4% for AT with the inclusion of subject sex, age, ethnicity, scanning position, body mass index, and waist circumference in the model. The developed SM and AT models were validated in an additional 49 subjects. To achieve equivalent power to a study measuring total body SM or AT volumes, a study using a single abdominal image would require 17–24% more subjects for SM and 6–12% more subjects for AT. Measurement of a single abdominal image can thus provide estimates of total body SM and AT for group studies of healthy adults.

Introduction: Healthcare workers are a special public icon for the community because people would like to adopt and implement their knowledge, skill, attitude and behaviour for improving quality of health. People respect them for their knowledge and health behavior. It is believed that the level of health status of health workers as well as community should go ahead parallel but many researchers have noted that high risk behaviours (smoking, tobacco use, alcoholism, irregular diet intake, lack of exercise etc.) are prevalent among health workers. The result of this will be physical, psychological, familial and social disturbance, which might have an impact on health care delivery system of the country. The study was concerned to assess health status (body mass index, smoking and depression) of healthcare workers and its impact on social adjustment in Banke district of Nepal. Methods: A cross sectional study design was applied to conduct the research. One hundred and eight respondents were selected through random sampling from the purposive group. Data wa collected through interview by using interview schedule. SPSS-16 windows process was used to analyze data. Results: Most of the respondent (81.40%) were under the age group less than 30 years (M = 27.35, SD = 9.24 years). More than 57.40% of respondents were female. Most of them (68.50%) were unmarried. Maximum (82.20%) responders had normal Body Mass Index (18.5-24.99). Near about forty percent (38.9%) healthcare worker had faced social problems in their working area. Conclusion: Age (above 20 years) and male healthcare workers were more likely to smoke cigarettes. Depressed health workers were more likely to smoke cigarette. Depression could be observed as a determinant for social adjustment.

AbstractBackground: Differences in body fat (BF) distribution in patients with normal body mass index (BMI) with elevated alanine aminotransferase (ALT) remains poorly described.Objective: To determine the relationship between total BF, waist circumference (WC), insulin resistance (IR), and cardiometabolic risk profile in subjects with elevated ALT and normal BMI.Methods: We analyzed cross-sectional data from 4,914 US participants in the third National Health and Nutrition Examination Survey database, who were ≥20 years of age, had normal BMI, and had body composition assessed by bioimpedance.Results: Mean ± SD age was 41.4 ± 0.3 years, and 58% participants were women. BF was 20 ± 0.1% in men and 29.9 ± 0.1% in women. As total BF increased by tertiles, there was a tendency towards a higher prevalence of nonalcoholic fatty liver disease in men (6.1%, 6.5%, 9.5%, P = 0.13), but not in women (8.7%, 8.2%, 10.7%, P = 0.71). As WC increased by tertiles, there was a higher prevalence of elevated ALT in men (2.6%, 8.6%, 6.6%, P < 0.0001), but not in women. As ALT increased, men had significantly higher levels of nonhigh density lipoprotein cholesterol (HDL-C), increased apolipoprotein B, increased IR, and lower levels of C-reactive protein, whereas, women had higher levels of non-HDL-C and increased IR.Conclusion: In subjects with normal BMI, increased WC is associated with a higher prevalence of elevated ALT in men, but not in women. Higher levels of ALT correlated with a poor cardiometabolic risk profile.

<p>The balance of a person's body is affected by the Body Mass Index. Body Mass Index is the easiest way to estimate obesity as well as to be highly correlated with body fat mass, but it is also important to identify obese patients who have a risk of medical complications. Purpose of this study was to know correlation body mass index with the static balance of transtibial prosthesis user. The study was a quantitative research with a cross-sectional design. Location research in BBRSBD Prof. Dr. Soeharso Surakarta with sample were patients with post-amputation of transtibial as many as 15 people. Analysis of data was used correlation Pearson test. There was a correlation between body mass index with the static balance of transtibial prosthesis user, the coefficient correlation of -0.646 with significant and levels of correlation moderate. The value of normal body mass index has the highest static balance than lean body mass index and fat. Mass Index of the skinny body has a moderate static balance. Obese body mass index has the lowest static balance of body mass index thin and normal. </p>
