Exploring the physical activity of Iranian migrant women in the United Kingdom: a qualitative study

Purpose: This article explores the role migration has on the physical activity of Iranian migrant women living in the United Kingdom. Method: This qualitative study includes 22 first-generation Iranian migrant women, aged 24–64, residing in London. Data was collected through in-depth, semi-structured, individual interviews and was analyzed thematically. Results: The findings show that for those women from traditional backgrounds, migration corresponds with liberation from social and cultural pressures experienced in Iran and greater motivation to adopt a physically active lifestyle. However, for Iranian women who had arrived in the UK more recently and had a higher social standing in Iran, migration was associated with the loss of their careers, sources of income, and social networks. These issues were compounded by a lack of cohesion in Iranian migrant communities and poor access to local physical activity resources. This resulted in diminishing motivation and the subsequent de-prioritisation of the women’s physical activity, even though they had regularly engaged in physical activity in Iran. Conclusion: Despite migration leading to improving physical activity for some Iranian women, for others, migration leads to marginality in Britain. Local authorities and Iranian community organizations need to adopt innovative strategies to reach out to recent Iranian migrant women

Not as bad as you think: a comparison of the nutrient content of best price and brand name food products in Switzerland.

Several studies have shown that low-cost foods have an equivalent nutrient composition compared to high-cost foods, but such information is lacking in Switzerland. Thus, we compared the caloric and nutrient content of "best price" (BPF) and brand name foods (BNF) in Switzerland using the version 5.0 (April 2015) of the Swiss Food and Nutrient composition database. Over 4000 processed food items were included and 26 food categories were compared regarding total energy, protein, fat and carbohydrates, saturated fatty acids, sugar, fiber and sodium. BPF, namely core food categories like Bread, Red meat, White meat and Fish products, were 42%, 39%, 42% and 46% less expensive than their BNF equivalents, respectively. No differences were found between BPF and BNF regarding total energy and protein, fat and carbohydrates for most food categories. In the Cheese category, BPF had a lower caloric content than BNF [Median (interquartile range, IQR): 307 (249-355) vs. 365 (308-395) kcal/100 g, respectively, p < 0.001]; BPF also had lower fat and saturated fatty acid content but higher carbohydrate content than BNF (both p < 0.01). In the Creams and puddings group, BPF had lower fat 1.3 (0.9-1.7) vs. 6.0 (3.5-11.0) g/100 g and saturated fatty acid 0.6 (0.6-0.8) vs. 2.9 (2.3-6.0) g/100 g content than BNF (both p < 0.005). In the Tinned fruits and vegetables group, BPF had lower sodium content than BNF: 175 (0-330) vs. 370 (150-600) mg/100 g, p = 0.006. BPF might be a reasonable and eventually healthier alternative of BNF for economically deprived people in Switzerland

Impact of nutritional risk screening in hospitalized patients on management, outcome and costs: A retrospective study.

Hospitalized patients should be screened for nutritional risk and adequately managed. Being nutritionally 'at-risk' increases in-hospital mortality, length of stay (LOS) and costs, but the impact on actual costs has seldom been assessed. We aimed to determine nutritional risk screening and management in a Swiss university hospital. The impact of being nutritionally 'at-risk' on in-hospital mortality, LOS and costs was also assessed. Retrospective analysis of administrative data for years 2013 and 2014 from the department of internal medicine of the Lausanne university hospital (8541 hospitalizations, mean age 72.8 ± 16.5 years, 50.4% women). Being nutritionally 'at-risk' was defined as a Nutritional risk screening-2002 score ≥ 3 and nutritional managements were collected from medical records. Screening increased from 16.5% in 2013 to 41.9% in 2014 (p < 0.001), while prevalence of 'at-risk' patients remained stable (64.6% in 2013 and 62.7% in 2014, p = 0.37). Prevalence of 'at-risk' patients was highest in patients with cancer (85.3% in 2013 and 70.2% in 2014) and lowest in patients with disease of skin (42% in 2013 and 44.8% in 2014). Less than half of patients 'at-risk' received any nutritional management, and this value decreased between 2013 and 2014 (46.9% vs. 40.3%, p < 0.05). After multivariate adjustment, 'at-risk' patients had a 3.7-fold (95% confidence interval: 1.91; 7.03) higher in-hospital mortality and higher costs (excess 5642.25 ± 1479.80 CHF in 2013 and 5529.52 ± 847.02 CHF in 2014, p < 0.001) than 'not at-risk' patients, while no difference was found for LOS. Despite an improvement in screening, management of nutritionally 'at-risk' patients is not totally covered yet. Being nutritionally 'at-risk' affects three in every five patients and is associated with increased mortality and hospitalization costs

The development of a walkability audit. Based on Iranian cities pedestrian environment

Given its influence on public health and the vehicle usage, along with its negative consequences, walkability has attracted much attention in recent decades. Meanwhile, the development of a method to measure walkability of urban areas for the purpose of improving this feature is of utmost importance. Hence, after a comprehensive investigation of environmental measures which are related to the users’ walking behavior, the researchers attempted to develop an efficient and reliable environmental audit tool based on these measures. Following the development of a protocol for utilization and management of the tool, we designed two different tests to validate it. The participants were taught how to use the tool, then, it was tested in the Eram neighborhood of Shiraz (Fars province, Iran). The statistical analysis of the obtained data showed that 13 of the environmental measures were not reliable to be used in various environments. However, given the remaining 50 items, the tool is valid for being applied to other urban areas

Estimating the avoidable burden of certain modifiable risk factors in osteoporotic hip fracture using Generalized Impact Fraction (GIF) model in Iran

Backgrounds: The number of hip fractures, the most common complication of osteoporosis, has increased rapidly over the past decades. The goal of this study is to estimate the avoidable burden of certain modifiable risk factor of the condition using the Generalized Impact Fraction (GIF) model, which has been suggested and used by epidemiologists to overcome the drawbacks associated with the use of Attributable Fraction index. In addition to preventing a risk factor or the avoidable fraction of burden, this index can also calculate the change in the burden, when a risk factor is altered.Methods: International databases were searched through PubMed, CINAHLD, Embase using OVID and Google scholar. National resources were searched through IranDoc, IranMedex, SID and Journal sites. Other resources include abstract books and articles sent to the IOF congress. The following search strategy was used: (" Osteoporotic fracture" OR " Fragility Hip fracture" OR " Calcium" OR " vitamin D" OR " BMI" OR " lean body weight" OR " Physical activity" OR " exercise" OR " Smoke" ) AND (" prevalence" OR " incidence" OR " relative risk" ) and limited to " humans." Results: With regards to different scenarios already explained in modifying the studied risk factors, the greatest impact in reducing the prevalence of risk factors on osteoporotic hip fractures, was seen in low serum vitamin D levels, low physical activity and low intake of calcium and vitamin D, respectively. According to the fact that interventions for low serum vitamin D and low intake of calcium and vitamin D, are related to each other, it can be concluded that implementing interventions to change these two risk factors, in the easy, moderate and difficult scenarios, would result in approximately a 5%, 11% and 17% decrease in the burden of osteoporotic hip fractures, respectively. The addition of interventions addressing low physical activity in the easy, moderate and difficult scenarios, an 8%, 21% and 35% reduction in the burden of osteoporotic hip fractures would be reported, respectively.Conclusion: Improving serum vitamin D levels, recommending the consumption of calcium and vitamin D supplementations and advocating physical activity are the most effective interventions to reduce the risk of osteoporotic hip fractures. © 2013 Shahnazari et al; licensee BioMed Central Ltd

Casimir force in the presence of a magnetodielectric medium

In this article we investigate the Casimir effect in the presence of a medium by quantizing the Electromagnetic (EM) field in the presence of a magnetodielectric medium by using the path integral formalism. For a given medium with definite electric and magnetic susceptibilities, explicit expressions for the Casimir force are obtained which are in agree with the original Casimir force between two conducting parallel plates immersed in the quantum electromagnetic vacuum.Comment: 8 pages, 1 figur

Multimodal Damping of a Nonlinear Structure with a Passive Piezoelectric Network

International audienceThis work proposes the implementation of a multimodal and fully passive piezoelectric tuned vibration absorber that mitigates several resonances of a nonlinear structure. By extending a principle of similarity, an analogous electrical network is designed in order to reproduce the dynamics of the mechanical structure. Several electrical resonances are simultaneously tuned to the mechanical resonances, thus providing the equivalent of a multimodal vibration absorber from electromechanical coupling through an array of piezoelectric patches. Furthermore, the use of a nonlinear capacitor in the analogous network generates an autonomous adjustment of the electrical resonance frequencies when the structure reaches the nonlinear domain. The interest of this method is proved experimentally by mitigating vibration over a wide frequency range that covers the first three modes of a beam with cubic nonlinearity
