RESUMO

BACKGROUND: The epidemiology of autism in adults has relied on untested projections using childhood research. AIMS: To derive representative estimates of the prevalence of autism and key associations in adults of all ages and ability levels. METHOD: Comparable clinical diagnostic assessments of 7274 Adult Psychiatric Morbidity Survey participants combined with a population case-register survey of 290 adults with intellectual disability. RESULTS: The combined prevalence of autism in adults of all ages in England was 11/1000 (95% CI 3-19/1000). It was higher in those with moderate to profound intellectual disability (odds ratio (OR) = 63.5, 95% CI 27.4-147.2). Male gender was a strong predictor of autism only in those with no or mild intellectual disability (adjusted OR = 8.5, 95% CI 2.0-34.9; interaction with gender, P = 0.03). CONCLUSIONS: Few adults with autism have intellectual disability; however, autism is more prevalent in this population. Autism measures may miss more women with autism.

RESUMO

Studies of programmes of self-management support for chronic obstructive pulmonary disease (COPD) have been inconclusive. The Self-Management Programme of Activity, Coping and Education (SPACE) FOR COPD is a 6-week self-management intervention for COPD, and this study aimed to evaluate the effectiveness of this intervention in primary care. A single-blind randomised controlled trial recruited people with COPD from primary care and randomised participants to receive usual care or SPACE FOR COPD. Outcome measures were performed at baseline, 6 weeks and 6 months. The primary outcome was symptom burden, measured by the self-reported Chronic Respiratory Questionnaire (CRQ-SR) dyspnoea domain. Secondary outcomes included other domains of the CRQ-SR, shuttle walking tests, disease knowledge, anxiety, depression, self-efficacy, smoking status and healthcare utilisation. 184 people with COPD were recruited and randomised. At 6 weeks, there were significant differences between groups in CRQ-SR dyspnoea, fatigue and emotion scores, exercise performance, anxiety, and disease knowledge. At 6 months, there was no between-group difference in change in CRQ-SR dyspnoea. Exercise performance, anxiety and smoking status were significantly different between groups at 6 months, in favour of the intervention. This brief self-management intervention did not improve dyspnoea over and above usual care at 6 months; however, there were gains in anxiety, exercise performance, and disease knowledge.

RESUMO

Systemic inflammation, as evidenced by elevated inflammatory cytokines, is a feature of advanced renal failure and predicts worse survival. Dialysate IL-6 concentrations associate with variability in peritoneal small solute transport rate (PSTR), which has also been linked to patient survival. Here, we determined the link between systemic and intraperitoneal inflammation with regards to peritoneal membrane function and patient survival as part of the Global Fluid Study, a multinational, multicenter, prospective, combined incident and prevalent cohort study (n=959 patients) with up to 8 years of follow-up. Data collected included patient demographic characteristics, comorbidity, modality, dialysis prescription, and peritoneal membrane function. Dialysate and plasma cytokines were measured by electrochemiluminescence. A total of 426 survival endpoints occurred in 559 incident and 358 prevalent patients from 10 centers in Korea, Canada, and the United Kingdom. On patient entry to the study, systemic and intraperitoneal cytokine networks were dissociated, with evidence of local cytokine production within the peritoneum. After adjustment for multiple covariates, systemic inflammation was associated with age and comorbidity and independently predicted patient survival in both incident and prevalent cohorts. In contrast, intraperitoneal inflammation was the most important determinant of PSTR but did not affect survival. In prevalent patients, the relationship between local inflammation and membrane function persisted but did not account for an increased mortality associated with faster PSTR. These data suggest that systemic and local intraperitoneal inflammation reflect distinct processes and consequences in patients treated with peritoneal dialysis, so their prevention may require different therapeutic approaches; the significance of intraperitoneal inflammation requires further elucidation.

RESUMO

OBJECTIVE: Women with polycystic ovary syndrome (PCOS) are potentially at increased risk of cardiovascular (CV) diseases due to well-established risk factors, including insulin resistance, obesity and type 2 diabetes mellitus (T2DM). However, data showing excess CV events in this population are still lacking. We investigated the incidence and prevalence of CV events in a cohort of women with PCOS. DESIGN: Retrospective cohort study (total follow-up >12,000 person-years). SETTING: Leicester, Leicestershire and Rutland (Total Female population of 434,859), UK. PARTICIPANTS: Two thousand three hundred and one women with PCOS (mean age = 29.6 years) attending a speciality clinic in Leicestershire, UK. MAIN OUTCOMES MEASURES: T2DM, myocardial infarction (MI), angina, heart failure (HF), stroke and CV-related death. RESULTS: Incidence of T2DM, MI, angina, HF, stroke and CV death was respectively 3.6, 0.8, 1.0, 0.3, 0.0 and 0.4 per 1000 person-years. At the end of follow-up, the prevalence of MI in the age groups 45-54, 55-64 and >65 years was 1.9%, 6.0% and 27.3% and of angina was 2.6%, 6.0% and 27.3%, respectively. Age-group-specific odds ratios for the prevalence of MI and angina compared to the local female population ranged between 2.6 (95% CI: 1.0-6.3) and 12.9 (CI: 3.4-48.6) with the highest ratio being for MI in the group >65 years old. Age, history of hypertension and smoking had significant correlations with CV outcomes in the PCOS patients. CONCLUSION: We have shown a high incidence and age-group-specific prevalence of T2DM, MI and angina in the women with PCOS, with over a quarter having had MI or angina in those >65 years. These findings should be considered in the treatment strategies and long-term planning for women with PCOS.

RESUMO

INTRODUCTION: We have previously developed a supported self-management programme (SMP): Self-management Programme of Activity, Coping and Education for chronic obstructive pulmonary disease (COPD), which was successfully delivered on an individual basis. Payers expressed an interest in delivering the intervention in groups. AIM: To explore the feasibility, acceptability and clinical effectiveness of the intervention delivered and supported by healthcare professionals (HCPs) in groups within primary care. METHODS: A prospective, single-blinded randomised controlled trial was conducted, with follow-up at 6 and 9 months. Participants were randomly assigned to control (usual care) or intervention (a six-session, group-based SMP delivered over 5 months). The primary outcome was change in COPD Assessment Test (CAT) at 6 months.Semistructured focus groups were conducted with intervention participants to understand feasibility and acceptability. A focus group was conducted with HCPs who delivered the intervention to gain insight into any potential facilitators/barriers to implementing the intervention in practice. All qualitative data were analysed thematically. RESULTS: 193 participants were recruited, (median Medical Research Council (MRC) grade 2). There was no significant difference between the intervention and control group for the primary outcome (CAT). However, an improvement in self-reported patient activation (at 6 and 9 months), knowledge (at 6 months), mastery (at 6 and 9 months) and fatigue (at 6 months), in the intervention group compared with usual care was demonstrated.Qualitative results indicated that the intervention was acceptable to patients who took part in the intervention and HCPs valued the intervention, suggesting it might be best delivered early in the disease process. CONCLUSIONS: A supported self-management intervention is feasible and acceptable when delivered as a group-based intervention, by HCPs in the community.

RESUMO

Introduction: Coronavirus disease 2019 (COVID-19) has caused >3.5 million deaths worldwide and affected >160 million people. At least twice as many have been infected but remained asymptomatic or minimally symptomatic. COVID-19 includes central nervous system manifestations mediated by inflammation and cerebrovascular, anoxic, and/or viral neurotoxicity mechanisms. More than one third of patients with COVID-19 develop neurologic problems during the acute phase of the illness, including loss of sense of smell or taste, seizures, and stroke. Damage or functional changes to the brain may result in chronic sequelae. The risk of incident cognitive and neuropsychiatric complications appears independent from the severity of the original pulmonary illness. It behooves the scientific and medical community to attempt to understand the molecular and/or systemic factors linking COVID-19 to neurologic illness, both short and long term. Methods: This article describes what is known so far in terms of links among COVID-19, the brain, neurological symptoms, and Alzheimer's disease (AD) and related dementias. We focus on risk factors and possible molecular, inflammatory, and viral mechanisms underlying neurological injury. We also provide a comprehensive description of the Alzheimer's Association Consortium on Chronic Neuropsychiatric Sequelae of SARS-CoV-2 infection (CNS SC2) harmonized methodology to address these questions using a worldwide network of researchers and institutions. Results: Successful harmonization of designs and methods was achieved through a consensus process initially fragmented by specific interest groups (epidemiology, clinical assessments, cognitive evaluation, biomarkers, and neuroimaging). Conclusions from subcommittees were presented to the whole group and discussed extensively. Presently data collection is ongoing at 19 sites in 12 countries representing Asia, Africa, the Americas, and Europe. Discussion: The Alzheimer's Association Global Consortium harmonized methodology is proposed as a model to study long-term neurocognitive sequelae of SARS-CoV-2 infection. Key Points: The following review describes what is known so far in terms of molecular and epidemiological links among COVID-19, the brain, neurological symptoms, and AD and related dementias (ADRD)The primary objective of this large-scale collaboration is to clarify the pathogenesis of ADRD and to advance our understanding of the impact of a neurotropic virus on the long-term risk of cognitive decline and other CNS sequelae. No available evidence supports the notion that cognitive impairment after SARS-CoV-2 infection is a form of dementia (ADRD or otherwise). The longitudinal methodologies espoused by the consortium are intended to provide data to answer this question as clearly as possible controlling for possible confounders. Our specific hypothesis is that SARS-CoV-2 triggers ADRD-like pathology following the extended olfactory cortical network (EOCN) in older individuals with specific genetic susceptibility.The proposed harmonization strategies and flexible study designs offer the possibility to include large samples of under-represented racial and ethnic groups, creating a rich set of harmonized cohorts for future studies of the pathophysiology, determinants, long-term consequences, and trends in cognitive aging, ADRD, and vascular disease.We provide a framework for current and future studies to be carried out within the Consortium. and offers a "green paper" to the research community with a very broad, global base of support, on tools suitable for low- and middle-income countries aimed to compare and combine future longitudinal data on the topic.The Consortium proposes a combination of design and statistical methods as a means of approaching causal inference of the COVID-19 neuropsychiatric sequelae. We expect that deep phenotyping of neuropsychiatric sequelae may provide a series of candidate syndromes with phenomenological and biological characterization that can be further explored. By generating high-quality harmonized data across sites we aim to capture both descriptive and, where possible, causal associations.

RESUMO

BACKGROUND: Epithelial dysfunction has been implicated in asthma pathophysiology, but no studies have directly assessed ciliary function in asthma. OBJECTIVE: To study the ciliary function and epithelial ultrastructure of patients with asthma and healthy controls. METHODS: We studied ciliary beat frequency and beat pattern by using digital high-speed video imaging and ultrastructure by transmission electron microscopy of bronchial epithelial strips from 7 subjects with mild, 7 with moderate, and 19 with severe asthma and 9 healthy controls. RESULTS: The median (interquartile range) ciliary beat frequency was decreased in moderate (6.5 [4.4-8.5] Hz) and severe asthma (6.7 [6.1-7.6] Hz) compared with controls (10.5 [9.7-11.8] Hz; P < .01). Dyskinesia and immotility indices were higher in severe asthma (65% [43%-75%]; 6.3% [1%-9.5%], respectively) compared with controls (4% [0%-6.7%; 0%, respectively; P < .01). These abnormalities were related to disease severity (ciliary beat frequency, r(s) = -0.68; dyskinesia index, r(s) = 0.86; immotility index, r(s) = 0.65; P < .0001). The ultrastructure of the epithelium was abnormal in severe asthma with a reduction in ciliated cells, an increase in dead cells, and ciliary disorientation compared with all other groups (P < .05). Compared with patients with mild asthma and healthy controls, patients with severe asthma showed increased ciliary depletion, microtubular defects, mitochondrial damage, and cytoplasmic blebbing (P < .01). All of these changes were related to disease severity. CONCLUSION: Ciliary dysfunction and ultrastructural abnormalities are closely related to asthma severity. Ciliary dysfunction is a feature of moderate to severe asthma, and profound ultrastructural abnormalities are restricted to severe disease. Whether these changes contribute to the development of severe asthma phenotype remains to be determined.

RESUMO

AIMS AND METHOD: We aimed to explore access by Black, Asian and minority ethnic (BAME) elders to the memory services in Leicester and Leicestershire, examining any trends over time. We then compared the odds of referral by ethnicity, using observed versus expected referrals for the city of Leicester. We gathered data on a comprehensive county-wide memory clinic used by people with suspected dementia and memory problems from the Trust electronic record system during the period 2011-2017. For Leicester city, we compared referral rates for 2011-2017 and compared observed and expected referral rates with demographics from the UK Census 2011. RESULTS: In Leicester, there was a significant underrepresentation of referrals from the BAME population as compared with the White population in 2011, 2012 and 2013, when compared with population estimates of those aged ≥60 years from the 2011 UK Census Leicester city data. Data for the Black population were too small for comparisons. The odds of being referred to a memory clinic for the White group was double that of the Asian group in 2011 (odds ratio 2.15, 95% CI 1.52-3.02) and nearly 1.5 times in 2012 (odds ratio 1.40, 95% CI 1.01-1.93). This difference did not persist after 2014. However, this differential odds of referral changes when the age difference between the groups is accounted for. After adjusting for age, there were no differences between the two groups in their odds of referral to the memory clinic from 2011 to 2013, but from 2014 to 2017, members of the Asian group had higher odds of being referred. CLINICAL IMPLICATIONS: The relationship between BAME and access to memory services is complex. The relative lower prevalence of Asian people among referrals to memory services in Leicester from 2011 to 2013 may partly be explained by the lower ages of the Asian population at referral. The higher prevalence of Asian people in 2014-2017 may be owing to use of denominators from the 2011 UK Census, which are likely to be disproportionately low for this group. Further studies are needed to explore any potential barriers to the access of services by BAME communities.

RESUMO

BACKGROUND: The incidence of dementia in Black, Asian and minority ethnic (BAME) groups is increasing in the UK, with concern about underdiagnosis and late presentation. AIMS: By reviewing referrals to memory clinics from Leicester City we examined whether the following differed by ethnicity: the proportion with a diagnosis of dementia, type of dementia and severity at presentation. METHOD: We examined referrals between 2010 and 2017: all those whose ethnicity was recorded as Black (n = 131) and a random sample of 260 Asian and 259 White British referrals. Severity of dementia was assessed by record review. Odds ratios (ORs) were adjusted for general practice, age, gender and year of referral. RESULTS: A diagnosis of dementia was recorded in 193 (74.5%) White British, 96 (73.3%) Black and 160 (61.5%) Asian referrals. Compared with Asians, White British had twice the adjusted odds of a dementia diagnosis (OR = 1.99 (1.23-3.22). Of those with dementia, Alzheimer's disease was more common in White British (57.0%) than in Asian (43.8%) and Black referrals (51.0%): adjusted OR White British versus Asian 1.76 (1.11-2.77). Of those with dementia, the proportion with moderate/severe disease was highest in White British (66.8%), compared with 61.9% in Asian and 45.8% in Black groups. The adjusted OR for the White versus Black groups was 2.03 (1.10-3.72), with no significant difference between Asian and White British groups. CONCLUSIONS: Differences in confirmed dementia suggest general practitioners have a lower threshold for referral for possible dementia in some BAME groups. Unlike other centres, we found no evidence of greater severity at presentation in Asian and Black groups.

RESUMO

RATIONALE: Impaired skeletal muscle function contributes to exercise limitation in patients with chronic obstructive pulmonary disease (COPD). This is characterized by reduced mitochondrial adenosine triphosphate generation, and greater reliance on nonmitochondrial energy production. Dichloroacetate (DCA) infusion activates muscle pyruvate dehydrogenase complex (PDC) at rest, reducing inertia in mitochondrial energy delivery at the onset of exercise and diminishing anaerobic energy production. OBJECTIVES: This study aimed to determine whether DCA infusion enhanced mitochondrial energy delivery during symptom-limited maximal exercise, thereby reducing exercise-induced lactate and ammonia accumulation and, consequently, improving exercise performance in patients with COPD. METHODS: A randomized, double-blind crossover design was used. Eighteen subjects with COPD performed maximal cycle exercise after an intravenous infusion of DCA (50 mg/kg body mass) or saline (control). Exercise work output was determined, and blood lactate and ammonia concentrations were measured at rest, 1 and 2 minutes of exercise, peak exercise, and 2 minutes postexercise. MEASUREMENTS AND MAIN RESULTS: DCA infusion reduced peak blood lactate concentration by 20% (mean [SE]; difference, 0.48 [0.11] mmol/L, P < 0.001) and peak blood ammonia concentration by 15% (mean [SE]; difference, 14.2 [2.9] mumol/L, P < 0.001] compared with control. After DCA, peak exercise workload improved significantly by a mean (SE) of 8 (1) W (P < 0.001) and peak oxygen consumption by 1.2 (0.5) ml/kg/minute (P = 0.03) compared with control. CONCLUSIONS: We have shown that a pharmacologic intervention known to activate muscle PDC can reduce blood lactate and ammonia accumulation during exercise and improve maximal exercise performance in subjects with COPD. Skeletal muscle PDC activation may be a target for pharmacologic intervention in the management of exercise intolerance in COPD.

RESUMO

Children with conduct disorders (CD) and their families are in contact with multiple agencies, but there is limited evidence on their patterns of service utilization. The aim of this study was to establish the patterns, barriers and correlates of service use by analysing the cohort of the 2004 Great Britain child mental health survey (N = 7,977). Use of social services was significantly higher by children with CD than emotional disorders (ED) in the absence of co-morbidity, while use of specialist child mental health and paediatric was significantly higher by children with hyperkinetic disorders (HD) than CD. Children who had comorbid physical disorders used more primary healthcare services compared to those without physical disorders. Utilization of specialist child mental heath and social services was significantly higher among children with unsocialized CD than socialized CD and oppositional defiant disorders. Services utilization and its correlates varied with the type of service. Overall, specialist services use was associated with co-morbidity with learning disabilities, physical and psychiatric disorders. Several correlates of services use in CD appeared non-specific, i.e. associated with use of different services indicating the possibility of indiscriminate use of different types of services. The findings led to the conclusion that there is the need for effective organization and co-ordination of services, and clear care pathways. Involvement of specialist child mental health services should be requested in the presence of mental health co-morbidity.

RESUMO

BACKGROUND: A previous study found that variables related to population health needs were poor predictors of cross-sectional variations in practice payments. AIM: To investigate whether deprivation scores predicted variations in the increase over time of total payments to general practices per patient, after adjustment for potential confounders. DESIGN AND SETTING: Longitudinal multilevel model for 2013-2017; 6900 practices (84.4% of English practices). METHOD: Practices were excluded if total adjusted payments per patient were <£10 or >£500 per patient or if deprivation scores were missing. Main outcome measures were adjusted total NHS payments; calculated by dividing total NHS payments, after deductions and premises payments, by the number of registered patients in each practice. A total of 17 independent variables relating to practice population and organisational factors were included in the model after checking for collinearity. RESULTS: After adjustment for confounders and the logarithmic transformation of the dependent and main independent variables (due to extremely skewed [positive] distribution of payments), practice deprivation scores predicted very weakly longitudinal variations in total payments' slopes. For each 10% increase in the Index of Multiple Deprivation score, practice payments increased by only 0.06%. The large sample size probably explains why eight of the 17 confounders were significant predictors, but with very small coefficients. Most of the variability was at practice level (intraclass correlation = 0.81). CONCLUSION: The existing NHS practice payment formula has demonstrated very little redistributive potential and is unlikely to substantially narrow funding gaps between practices with differing workloads caused by the impact of deprivation.

RESUMO

The higher prevalence of autism reported in blind children has been commonly attributed to the confounding effects of an underlying intellectual disability. The aim of this study was to explore the relationship between symptoms of autism and blindness in adults with intellectual disability. We hypothesized that blindness can increase the probability of the autism phenotype, independent of known risk factors, that is, severity of intellectual disability and gender. A general population case register (population size of 0.7 million) was used to conduct two studies. The first study was on 3,138 adults with intellectual disability, using a validated autism risk indicator to study adults with visual impairment. This identified 386 adults with partial and complete visual impairment, both of which were associated with presence of high number of autistic traits (P < 0.001). The second study was only on those with congenital blindness using a standardized assessment tool, the Pervasive Developmental Disorder-Mental Retardation Scale. Those with hearing impairment or unilateral, partial, and acquired visual impairment were excluded. Control groups were randomly selected from those with normal hearing and vision. Prevalence of the autism phenotype was higher among those with congenital blindness (n = 46/60; 76.7%) than their controls (n = 36/67; 53.7%) and this association was statistically significant (adjusted odds ratio = 3.03; 95% confidence interval: 1.34-6.89; P = 0.008). Our results support the hypothesis that a congenital blindness independently affects psychosocial development and increases the probability of the autism phenotype. Early identification of autism could facilitate appropriate psychosocial interventions and educational opportunities to improve quality of life of people with blindness. Autism Res 2019, 12: 1411-1422. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Although autism has been commonly reported in those with blindness, it is generally attributed to an accompanying intellectual disability. Current study, however, revealed that congenital blindness is independently associated with symptoms of autism. In spite of its high prevalence, autism can be overlooked in those with intellectual disability and blindness. Improving diagnosis in this population should, therefore, be advocated through raising awareness of this association to facilitate early access to services.

RESUMO

AIM: To examine system characteristics associated with variations in unplanned admission rates in those aged 85+. DESIGN: Mixed methods. SETTING: Primary care trusts in England were ranked according to changes in admission rates for people aged 85+ between 2007 and 2009, and study sites selected from each end of the distribution: three 'improving' sites where rates had declined by more than 4% and three 'deteriorating' sites where rates had increased by more than 20%. Each site comprised an acute hospital trust, its linked primary care trust/clinical commissioning group, the provider of community health services and adult social care. PARTICIPANTS: A total of 142 representatives from these organisations were interviewed to understand how policies had been developed and implemented. McKinsey's 7S framework was used as a structure for investigation and analysis. RESULTS: In general, improving sites provided more evidence of comprehensive system focused strategies backed by strong leadership, enabling the development and implementation of policies and procedures to avoid unnecessary admissions of older people. In these sites, primary and intermediate care services appeared more comprehensive and better integrated with other parts of the system, and policies in emergency departments were more focused on providing alternatives to admission. CONCLUSIONS: Health and social care communities which have attenuated admissions of people aged 85+ prioritised developing a shared vision and strategy, with sustained implementation of a suite of interventions.

RESUMO

OBJECTIVES: In England, many hypertensives are not detected by primary medical care. Higher detection is associated with lower premature mortality. We aimed to summarise recent evidence on detection and interventions to improve detection in order to inform policies to improve care. DESIGN: Data sources: systematic review of articles published since 2000. Searches of Medline and Embase were undertaken. Eligibility criteria: published in English, any study design, the setting was general practice and studies included patients aged 18 or over. EXCLUSION CRITERIA: screening schemes, studies in primary care settings other than general practice, discussion or comment pieces. PARTICIPANTS: adult patients of primary medical care services. SYNTHESIS: study heterogeneity precluded a statistical synthesis, and papers were described in summary tables. RESULTS: Seventeen quantitative and one qualitative studies were included. Detection rates varied by gender and ethnic group, but longitudinal studies indicated an improvement in detection over time. Patient socioeconomic factors did not influence detection, but living alone was associated with lower detection. Few health system factors were associated with detection, but in two studies higher numbers of general practitioners per 1000 population were associated with higher detection. Three studies investigated interventions to improve detection, but none showed evidence of effectiveness. LIMITATIONS: The search was limited to studies published from 2000, in English. There were few studies of interventions to improve detection, and a meta-analysis was not possible. CONCLUSIONS AND IMPLICATIONS: Levels of detection of hypertension by general practices may be improving, but large numbers of people with hypertension remain undetected. Improvement in detection is therefore required, but guidance for primary medical care is not provided by the few studies of interventions included in this review. Primary care teams should continue to use low-cost, practical approaches to detecting hypertension until evidence from new studies of interventions to improve detection is available.

RESUMO

BACKGROUND: Increased relationship continuity in primary care is associated with better health outcomes, greater patient satisfaction, and fewer hospital admissions. Greater socioeconomic deprivation is associated with lower levels of continuity, as well as poorer health outcomes. AIM: To investigate whether deprivation scores predicted variations in the decline over time of patient-perceived relationship continuity of care, after adjustment for practice organisational and population factors. DESIGN AND SETTING: An observational study in 6243 primary care practices with more than one GP, in England, using a longitudinal multilevel linear model, 2012-2017 inclusive. METHOD: Patient-perceived relationship continuity was calculated using two questions from the GP Patient Survey. The effect of deprivation on the linear slope of continuity over time was modelled, adjusting for nine confounding variables (practice population and organisational factors). Clustering of measurements within general practices was adjusted for by using a random intercepts and random slopes model. Descriptive statistics and univariable analyses were also undertaken. RESULTS: Relationship continuity declined by 27.5% between 2012 and 2017, and at all deprivation levels. Deprivation scores from 2012 did not predict variations in the decline of relationship continuity at practice level, after accounting for the effects of organisational and population confounding variables, which themselves did not predict, or weakly predicted with very small effect sizes, the decline of continuity. Cross-sectionally, continuity and deprivation were negatively correlated within each year. CONCLUSION: The decline in relationship continuity of care has been marked and widespread. Measures to maximise continuity will need to be feasible for individual practices with diverse population and organisational characteristics.

RESUMO

BACKGROUND: Developments in primary care may make the provision of interpersonal continuity more difficult. AIM: To identify those patients who regard interpersonal continuity as important and determine what makes it difficult for them to obtain this. DESIGN OF STUDY: Cross sectional survey. SETTING: Twenty-two practices and a walk-in centre in West London and Leicestershire, UK. METHOD: Administration of a questionnaire on preferences for and experiences of interpersonal and informational continuity. Interpersonal continuity was defined in three questions: choosing a particular person; choosing someone known and trusted; and choosing someone who knows the patient and medical condition. RESULTS: One thousand four hundred and thirty-seven (46.5%) patients responded. Consulting someone known and trusted was important to 766 (62.6%) responders, although 105 (13.7%) of these reported that they had not experienced it at their last consultation. Seven hundred and eighty-eight (65.2%) responders regarded being able to consult a particular person as important, but 168 (21.3%) of these were unable to. Being in work and consulting for a new problem were associated with failing to obtain interpersonal continuity. Ethnic group was associated with failing to see someone with time to listen when this was preferred. CONCLUSION: In view of the response rate, which was particularly low among young males, some caution is required in applying the findings. Most patients experience the aspects of care important to them, although interpersonal continuity is important to many and certain groups find difficulty in obtaining it. Practices should have flexible appointment systems to account for the difficulties some patients have in negotiating for the type of care they want.

RESUMO

BACKGROUND: Childhood obesity is an escalating health concern with important implications, including increased risk of type 2 diabetes and cardiovascular disease. Although South Asians in the UK have an increased risk of developing these conditions, detailed studies on their lifestyles including the dietary habits of young people are scarce. METHODS: As part of an action research project, a food intake questionnaire was used to survey the dietary habits of 11-15-year olds attending five inner-city schools serving a predominantly South Asian population. Food choices were considered in the overall sample and in South Asians compared with white Europeans. RESULTS: 3418 (72% of registered pupils) responses were obtained. A subset of 3018 pupils could be categorised as either South Asian (86%) or white European (14%). Around one fifth of pupils started the school day without eating anything. Responses indicated high consumption of "negative" foods such as sweets, including Asian sweets (63%), but lower rates for "positive" foods such as vegetables (34%). In the full sample, 26% said they had consumed more than one can of sugar-sweetened fizzy drink and 17% reported eating more than one packet of full-fat crisps on the previous day. Poor dietary habits were indicated in both South Asian and white European pupils. CONCLUSIONS: Our large-scale survey confirmed poor dietary habits in secondary school pupils from a multiethnic community. Urgent efforts are needed to find ways of encouraging healthy lifestyles, particularly in populations with a high risk of developing cardiovascular disease and type 2 diabetes.
