What is already known about this subject The increase in the prevalence of obesity among children and adolescents in England has stabilized following a peak in 2004 and 2005., This stabilization conceals continued rises among more deprived and certain ethnic minority groups., It is unclear which ethnic groups in the UK experience the highest rates of overweight/obesity, how this has changed over time and how these patterns relate to socioeconomic differences between the groups., What this study adds Trends over time suggested that overweight/obesity rates for ethnic minority groups had not peaked, unlike those for white English groups., Black African children had higher rates of overweight and obesity, and black Caribbean children had higher rates of obesity., Differences were not explained by variations in equivalized household income., Background The increase in the prevalence of obesity among children and adolescents in England since the mid-1990s has been dramatic. Cross-sectional evidence suggests ethnic variations in childhood obesity prevalence. Objectives The objective of the study was to examine whether and how ethnic variations in childhood overweight/obesity have changed over time, and are affected by socioeconomic factors. Method This study uses logistic regression to analyse ethnic differences in the relative likelihood of being at or above the age- and gender-specific thresholds for overweight and obesity developed by the International Obesity Task Force among children aged between 2 and 15 from 11 ethnic groups included in the Health Surveys for England between 1998 and 2009, adjusting for age, gender, year of data collection and equivalized household income. We separately analyse the likelihood of being at or above the thresholds for overweight (but below those for obesity) and obesity. Results Trends in overweight/obesity over time among ethnic minority groups do not follow those of white English children. Black African children had higher rates of overweight and obesity, which appear to have peaked, and black Caribbean children had higher rates of obesity than other groups examined, which appear to continue rising. These differences were not explained by socioeconomic variations between groups. Conclusion Policies are required that encourage healthy lifestyles among ethnic minority young people, while engaging with the complexities associated with these choices during childhood and adolescence.

Community severance occurs where road traffic (speed or volume) inhibits access to goods, services, or people. Appleyard and Lintell's seminal study of residents of three urban streets in San Francisco found an inverse relationship between traffic and social contacts. The extent of social networks predicts unhealthy behaviors, poor health, and mortality; high rather than low social integration is associated with reduced mortality, with an effect size of similar magnitude to stopping smoking. Although community severance diminishes social contacts, the implications of community severance for morbidity and mortality have not been empirically established. Based on a systematic literature search, we discuss what is actually known about community severance. There is empirical evidence that traffic speed and volume reduces physical activity, social contacts, children's play, and access to goods and services. However, no studies have investigated mental or physical health outcomes in relation to community severance. While not designed specifically to do so, recent developments in road design may also ameliorate community severance. [ABSTRACT FROM AUTHOR]

Background. The aim of this study was to explore the relationship between risk of psychosis, common mental disorder (CMD) and indicators of racism among ethnic minority groups in England and how this relationship may vary by particular ethnic groups.Method. A multivariate analysis was carried out of quantitative, cross-sectional data from a nationally representative community sample of people aged between 16 and 74 years from the largest ethnic minority groups in England: those of Caribbean, Indian, Pakistani, Bangladeshi and Irish origin.Results. Experience of interpersonal racism and perceiving racism in the wider society each have independent effects on the risk of CMD and psychosis, after controlling for the effects of gender, age and socio-economic status. There was some variation in the findings when they were conducted for separate ethnic and gender groups.Conclusions. An understanding of the relationship between racism and mental health may go some way towards explaining the ethnic variations found in both CMD and, particularly, psychosis. [ABSTRACT FROM AUTHOR]

We set out to explore the influence of environment on ethnic inequalities in health. Studies exploring the relationship between environment and health have tended to ignore the role of ethnicity, and the health impact of the residential concentration of ethnic minority groups in disadvantaged areas. Those that have explored the role of ethnicity tend to focus on the way in which residential concentration may promote a sense of community among ethnic minority groups, and, consequently, may be protective of health (the 'ethnic density effect'). Again, they have tended to ignore the health impact of the concentration of ethnic minority groups in areas of social and economic disadvantage. We undertook a factor analysis to determine aspects of perception of 'quality' of the local environment, followed by multi-level analyses to explore the relationship between self-reported fair or poor health and individual- and ward-level characteristics among four ethnic groups (Caribbean, Indian, Pakistani and Bangladeshi, and white) in the UK. Results of the factor analysis suggested three underlying dimensions of perception of quality of the local area, related to the quality of the local environment, the provision of local amenities and local problems of crime and nuisance. These factors were entered into the multi-level models at level 2, along with indicators of ward-level ethnic density and Townsend's deprivation score, with age, gender and household social class entered at level 1. In general, there was a residual random ward-level effect suggesting an area influence on self-assessed health. However, on the whole, none of the ward-level indicators showed any statistically significant association with self-assessed health, making it difficult to precisely determine the mechanisms operating. These findings suggest, though, that there is no ethnic density effect on self-assessed health for ethnic minority groups. [ABSTRACT FROM AUTHOR]

To understand ethnic inequalities in health, we must take account of the relationship between ethnic minority status, structural disadvantage and agency. So far, the direct effects of racial oppression on health, and the role of ethnicity as identity, which is in part a product of agency, have been ignored. We set out to redress this balance using data from the Fourth National Survey of Ethnic Minorities. Factor analysis suggested that dimensions of ethnic identity were consistent across the various ethnic minority groups. Initially some of these dimensions of ethnic identity appeared to be related to health, but in a multivariate model the factor relating to a racialised identity was the only one that exhibited any relationship with health. These findings suggest that ethnic identity is not related to health. Rather, the multivariate analyses presented here showed strong independent relationships between health and experiences of racism, perceived racial discrimination and class. [ABSTRACT FROM AUTHOR]

This paper reports on data from the Regional Study of Care for the Dying, conducted in 1990, and compares symptoms, care and service utilization for patients with chronic lung diseases (CLD) and lung cancer (LC) in the final 12 months of life. Post-bereavement structured interviews were conducted with informal carers of 449 LC patients and 87 CLD patients. The LC patients were significantly younger than those with CLD (P = 0.001) and these respondents were more likely to have been a spouse (P = 0.034). No differences were found in the mean number of symptoms reported by the two groups in the final year or week of life, although the CLD patients were more likely to have experienced these symptoms for longer. Significantly more patients with CLD than LC experienced breathlessness in the final year (94% CLD vs 78% LC, P < 0.001) and final week (91% CLD vs 69% LC, P < 0.001) of life. Significantly more LC patients were reported to have experienced anorexia (76% LC vs 67% CLD, P = 0.06) and constipation (59% LC vs 44% CLD, P = 0.01) in the final year of life. There were no differences in general practitioner use, but LC patients were reported to have received more help from district nurses (52% LC vs 39% CLD, P = 0.025) and from a palliative care nurse (29% LC vs 0% CLD, P < 0.001). More CLD patients were reported to have received help from social services (29% CLD vs 18% LC, P = 0.037). LC patients were reported to be more likely to have known they might die (76% LC vs 62% CLD, P = 0.003) and to have been told this by a hospital doctor (30% LC vs 8% CLD, P = 0.001). Among those that knew, LC patients were told earlier prior to death than CLD patients. This study suggests that patients with CLD at the end of life have physical and psychosocial needs at least as severe as patients with lung cancer. [ABSTRACT FROM AUTHOR]

Patient satisfaction surveys are seen as an important way of obtaining 'user views' of health service provision. However, there is a growing body of research and theoretical literature that questions the validity of the concept of 'patient satisfaction' and hence the use of this type of survey. A postbereavement survey of people who registered a random sample of cancer deaths in an inner London health authority was undertaken in 1996/7. The survey questionnaire (VOICES) included 14 open-ended questions which asked respondents to add any comments they felt were relevant about the care of the deceased. This paper uses these data to examine the causes of dissatisfaction with hospital-based care. Of the 229 informants responding to the questionnaire, 138 included some written comment about care in hospital. At least one negative comment was made by 59% (82) of those making any comment. Of these, 55% (44) rated the care given by doctors as 'excellent' or 'good' and 63% (50) rated that given by nurses as 'excellent' or 'good'. Qualitative analysis of responses to open questions suggest that expressions of dissatisfaction arise from a sense of being 'devalued', 'dehumanized' or 'disempowered' and from situations in which the 'rules' governing the expected health professional-patient relationships were broken. As such, the causes of dissatisfaction for this particular group of patients are similar to the causes of dissatisfaction with health care in general reported elsewhere. The palliative care approach emphasizes patient- and family-centred care and aims to promote physical and psychosocial well-being. The study findings suggest that adoption of the palliative care approach could reduce the experience of dissatisfaction for many service users, not only those whose deaths are anticipated.

Our objective was to investigate how cancer patients who die at home differ from those who do not. A postbereavement survey of 229 people who registered the death of a random sample of cancer deaths in an inner London health authority was conducted. It was found that a fifth of patients (21%) died in their own home. Overall, 38% were reported to have expressed a preference for place of death, 73% of whom wanted to die at home. Only 58% achieved this. Having special equipment and stating a preference for place of death was associated with an increased likelihood of dying at home; using social and health services for social care was associated with a decreased likelihood of so doing. It was concluded that, as in previous studies, most patients who expressed a preference wanted a home death, but nearly half did not achieve this. Recognition of a preference for home death, providing the motivation to `stick it out' at home, and adequate community support to provide the practical means to fulfil the preference, appear to be crucial in the achievement of a home death for all who desire it.

Manipulating joint range of motion during squat training may have differential effects on adaptations to strength training with implications for sports and rehabilitation. Consequently, the purpose of this study was to compare the effects of squat training with a short vs. a long range of motion. Male students ( n = 17) were randomly assigned to 12 weeks of progressive squat training (repetition matched, repetition maximum sets) performed as either a) deep squat (0-120° of knee flexion); n = 8 (DS) or (b) shallow squat (0-60 of knee flexion); n = 9 (SS). Strength (1 RM and isometric strength), jump performance, muscle architecture and cross-sectional area (CSA) of the thigh muscles, as well as CSA and collagen synthesis in the patellar tendon, were assessed before and after the intervention. The DS group increased 1 RM in both the SS and DS with ~20 ± 3 %, while the SS group achieved a 36 ± 4 % increase in the SS, and 9 ± 2 % in the DS ( P < 0.05). However, the main finding was that DS training resulted in superior increases in front thigh muscle CSA (4-7 %) compared to SS training, whereas no differences were observed in patellar tendon CSA. In parallel with the larger increase in front thigh muscle CSA, a superior increase in isometric knee extension strength at 75° (6 ± 2 %) and 105° (8 ± 1 %) knee flexion, and squat-jump performance (15 ± 3 %) were observed in the DS group compared to the SS group. Training deep squats elicited favourable adaptations on knee extensor muscle size and function compared to training shallow squats. [ABSTRACT FROM AUTHOR]

Background: Temporary vascular in- and outflow occlusion is an effective technique for bleeding control during liver resection. However, occlusion can result in ischemia/reperfusion (I/R) injury to the liver. The aim of this study in a porcine model was to investigate the effect of in- and outflow occlusion of part of the liver on the metabolism of the normally perfused parenchyma of the same liver measured by microdialysis. Methods: Eight pigs underwent laparotomy. A microdialysis catheter was inserted into in the left and right part of the liver, respectively. Microdialysis samples were collected every 30 min. Occlusion of the left part of the liver was achieved for 60 min, followed by 5 h of reperfusion. Samples were analyzed for glucose, lactate, pyruvate and glycerol. Blood samples were drawn to determine standard liver and biochemical parameters. Results: Comparing the ischemic part of the liver with the normally perfused part, significant differences in the levels of lactate, pyruvate and glycerol were found. During reperfusion, similar and continuous decreases below baseline levels were observed for lactate and pyruvate in both the ischemic and normally perfused part of the liver. No significant changes in liver parameters or blood glucose levels were seen. Conclusions: Partial ischemia of the liver is without effects on metabolism in the normally perfused part. Metabolic changes in the ischemic part of the liver were reversible. However, partial liver ischemia was followed by similar continuous decreases in lactate and pyruvate levels in the whole liver, even though the ischemic insult was not detectable in transaminase levels.

An NDVI dataset covering Fennoscandia and the Kola peninsula was created for vegetation and climate studies, using Moderate Resolution Imaging Spectroradiometer 16-day maximum value composite data from 2000 to 2005. To create the dataset, (1) the influence of the polar night and snow on the NDVI values was removed by replacing NDVI values in winter with a pixel-specific NDVI value representing the NDVI outside the growing season when the pixel is free of snow; and (2) yearly NDVI time series were modelled for each pixel using a double logistic function defined by six parameters. Estimates of the onset of spring and the end of autumn were then mapped using the modelled dataset and compared with ground observations of the onset of leafing and the end of leaf fall in birch, respectively. Missing and poor-quality data prevented estimates from being produced for all pixels in the study area. Applying a 5 km×5 km mean filter increased the number of modelled pixels without decreasing the accuracy of the predictions. The comparison shows good agreement between the modelled and observed dates (root mean square error = 12 days, n = 108 for spring; root mean square error = 10 days, n = 26, for autumn). Fennoscandia shows a range in the onset of spring of more than 2 months within a single year and locally the onset of spring varies with up to one month between years. The end of autumn varies by one and a half months across the region. While continued validation with ground data is needed, this new dataset facilitates the detailed monitoring of vegetation activity in Fennoscandia and the Kola peninsula. [ABSTRACT FROM AUTHOR]

Background. There is little population-based evidence on ethnic variation in the most common mental disorders (CMD), anxiety and depression. We compared the prevalence of CMD among representative samples of White, Irish, Black Caribbean, Bangladeshi, Indian and Pakistani individuals living in England using a standardized clinical interview.Method. Cross-sectional survey of 4281 adults aged 16-74 years living in private households in England. CMD were assessed using the Revised Clinical Interview Schedule (CIS-R), a standardized clinical interview.Results. Ethnic differences in the prevalence of CMD were modest, and some variation with age and sex was noted. Compared to White counterparts, the prevalence of CMD was higher to a statistically significant degree among Irish [adjusted rate ratios (RR) 2.09, 95% CI 1.16-2.95, p=0.02] and Pakistani (adjusted RR 2.38, 95% CI 1.25-3.53, p=0.02) men aged 35-54 years, even after adjusting for differences in socio-economic status. Higher rates of CMD were also observed among Indian and Pakistani women aged 55-74 years, compared to White women of similar age. The prevalence of CMD among Bangladeshi women was lower than among White women, although this was restricted to those not interviewed in English. There were no differences in rates between Black Caribbean and White samples.Conclusions. Middle-aged Irish and Pakistani men, and older Indian and Pakistani women, had significantly higher rates of CMD than their White counterparts. The very low prevalence of CMD among Bangladeshi women contrasted with high levels of socio-economic deprivation among this group. Further study is needed to explore reasons for this variation.
