RESUMO
BACKGROUND: As people with intellectual disabilities (ID) are now living longer, they are more at risk of developing non-communicable diseases, including type 2 diabetes mellitus. However, understanding of factors associated with diabetes for targeted management and prevention strategies is limited. This study aimed to investigate prevalence of diabetes in adults (aged ≥18 years) with ID and its relationship with demographic, lifestyle, independence and health factors. METHOD: This was a cross-sectional analysis of interview data from 1091 adults with ID from the Leicestershire Learning Disability Register from 1 January 2010 to 31 December 2016. Logistic regression models were used to identify factors associated with diabetes in the study population. RESULTS: The study population did not have healthy lifestyles: just under half reported having lower physical activity levels than people without ID of a similar age; one-quarter consumed fizzy drinks daily; and 20% consumed five or more fruit and/or vegetables per day. Prevalence of carer/self-reported diabetes was 7.3% (95% confidence interval 5.9-9.0). After adjustment, diabetes was positively associated with South Asian ethnicity (P = 0.03) and older age groups (P < 0.001). Diabetes was less common in people living with family members (P = 0.02). We did not find a relationship between any of the lifestyle, independence and health factors investigated. CONCLUSIONS: A significant proportion of people with ID are living with diabetes. Diabetes management and prevention strategies should be tailored to individuals' complex needs and include consideration of lifestyle choices. Such strategies may want to focus on adults of South Asian ethnicity and people living in residential homes where prevalence appears to be higher.

BACKGROUND: Multimorbidity [two or more conditions in addition to intellectual disability (ID)] is known to be more common among people with ID. However, the relationship between multimorbidity and lifestyle factors is currently unknown. The aim of this study was to determine the prevalence of multimorbidity in a population of adults with ID. We also aimed to identify risk factors, including lifestyle factors, for multimorbidity in this population. METHODS: This was a cross-sectional analysis using data from a diabetes screening study of 920 adults aged 18-74 years with ID living in Leicestershire, UK. We described comorbidities and the prevalence of multimorbidity in this population. We explored the relationship between multimorbidity and age, gender, ethnicity, severity of ID, socio-economic status, physical activity, sedentary behaviour, fruit and vegetable consumption and smoking status using multiple logistic regression. RESULTS: The prevalence of multimorbidity was 61.2% (95% CI 57.7-64.7). Multimorbidity was independently associated with being female (P < 0.001) and severe/profound ID (P = 0.004). Increasing age was of borderline significance (P = 0.06). Individuals who were physically inactive or sedentary were more likely to be multimorbid, independent of ability to walk, age, gender, severity of ID, ethnicity and socio-economic status (adjusted OR = 1.91; 95% CI 1.23-2.97; P = 0.004 and OR = 1.98; 95% CI 1.42-2.77; P < 0.001). After excluding probable life-long conditions (autism spectrum conditions, attention deficit hyperactivity disorders, epilepsy, cerebral palsy and other paralytic syndromes) as contributing comorbidities, the effect of sedentary behaviour, but not physical activity, remained (P = 0.004). We did not observe a relationship between multimorbidity, fruit and vegetable consumption and smoking status. CONCLUSIONS: Multimorbidity presents a significant burden to people with ID. Individuals who were physically inactive or sedentary were more likely to be multimorbid, but further work is recommended to explore the relationship between multimorbidity and lifestyle factors using standardised objective measures.

Background: We report on the development of the 'STOP Diabetes' education programme, a multi-component lifestyle behaviour change intervention for the prevention of type 2 diabetes and cardiovascular risk factors in adults with intellectual disabilities (ID). Methods: We combined qualitative stakeholder interviews with evidence reviews to develop the intervention, guided by the MRC Framework and informed by intervention mapping and two existing diabetes prevention programmes. We conducted two pilot cycles drawing on additional stakeholder interviews to inform and refine the intervention. Results: The STOP Diabetes education programme employed a theoretical framework, using sound learning and behavioural principles and concrete kinaesthetic methods, to provide the grounding for innovative games and activities to promote health behaviour change in adults with ID. Qualitative data also suggested that two educators and one support person delivering a programme of one carer session followed by seven 2.5-h sessions over 7 weeks was acceptable to service users, carers and educators and appeared to benefit the participants. Conclusions: The STOP Diabetes education programme was successfully developed and is suitable for a definitive randomized controlled trial.

BACKGROUND: Adults with intellectual disabilities (ID) may be at increased risk of developing type 2 diabetes and cardiovascular disease, due to lifestyle factors, medications and other diagnosed conditions. Currently, there is lack of evidence on prevalence and prevention in this population. The aim of this study was to conduct a diabetes screening programme to determine prevalence of previously undiagnosed type 2 diabetes and impaired glucose regulation in people with ID. METHODS: Screening was conducted in a variety of community settings in Leicestershire, UK. Adults with ID were invited via: general practices; the Leicestershire Learning Disability Register; ID psychiatric services; and some people directly contacted the research team due to publicity about the study. Screening involved collection of anthropometric, biomedical and questionnaire data. Type 2 diabetes and impaired glucose regulation were defined according to (venous) fasting plasma glucose or HbA1c, following current World Health Organisation criteria. RESULTS: Nine hundred thirty adults (29% of those approached) participated. Mean age was 43 years, 58% were male and 16% of South Asian ethnicity. Most participants were either overweight or obese (68%). Diabetes status was successfully assessed for 675 (73%) participants: Nine (1.3%, 95% confidence interval 0.6 to 2.5) were found to have undiagnosed type 2 diabetes, and 35 (5.2%, 95% confidence interval 3.6 to 7.1) had impaired glucose regulation. Key factors associated with abnormal glucose regulation included the following: non-white ethnicity and a first degree family history of diabetes. CONCLUSIONS: Results from this large multi-ethnic cohort suggest a low prevalence of screen-detected (previously undiagnosed) type 2 diabetes and impaired glucose regulation in adults with ID. However, the high levels of overweight and obesity we found emphasise the need for targeted lifestyle prevention strategies, which are specifically tailored for the needs of people with ID.

BACKGROUND: People with intellectual disability (ID) and epilepsy are more likely to die prematurely than the general population. A significant number of deaths in people with epilepsy may be potentially preventable through better seizure control, regular monitoring and raising awareness among patients and carers. The aim of this project was to study mortality from sudden unexpected death in epilepsy (SUDEP) in adults with ID. METHODS: All adults (≥20 years old) living in Leicester city, Leicestershire and Rutland, UK, with ID between 1993 and 2010 were identified using the Leicestershire Intellectual Disability Register database. People with and without ID who died during the same period were identified using death certificate data from the Office for National Statistics (ONS). Deaths from probable and definite SUDEP were identified. Additional information on adults with ID who had died from probable or definite SUDEP was obtained from case notes and post-mortem reports, where available. Cases of probable and definite SUDEP in adults with ID were compared with the general population using standardised mortality ratios (SMRs). RESULTS: A total of 898 adults with ID had died over the 18-year study period. Of these, 244 deaths (27%) occurred in people with ID who had a diagnosis of epilepsy. Twenty-six people with ID died from probable or definite SUDEP, which was the second most common cause of death among adults with ID and epilepsy. All-cause specific SMRs were 2.2 [95% confidence interval (CI): 2.0-2.4] and 2.8 (95% CI: 2.5-3.1) for men and women with ID respectively. SMRs were 3.2 (95% CI: 2.7-3.8) and 5.6 (95% CI: 4.6-6.7) for men and women with epilepsy and ID respectively. During the same study period, 83 adults without ID had died of probable or definite SUDEP. The SMRs for SUDEP in patients with ID were 37.6 for men (95% CI: 21.9-60.2) and 52.0 for women (95% CI: 23.8-98.8). We found that in the majority of ID cases there was little detailed documentation on the circumstances surrounding deaths, no communication with patients/carers about risk of SUDEP and an absence of post-mortem reports or carers' referral for bereavement counselling. CONCLUSION: The authors believe that a comprehensive risk management under a multiagency/multidisciplinary framework should be undertaken for all adults with ID and epilepsy in day-to-day clinical practice to reduce mortality in people with ID.

BACKGROUND: In the general population there are statistically significant urban-rural differences in the rate of common mental disorders. In people with intellectual disability (ID) no study has attempted to address this issue. AIMS: To compare the prevalence of mental illness, autism spectrum disorder (ASD) and behaviour disorder in people with ID living in urban areas with those living in rural areas. METHODS: Cross-sectional study of 2713 individuals registered with an ID service. Participants were assigned to urban or rural groups using the Department for Environment Food and Rural Affairs rural/urban local authority classification for their district. The main outcome variable was a clinical diagnosis of mental illness, ASD and behaviour disorder. Differences between diagnoses of mental illness in urban and rural areas were evaluated using the chi-squared test for the difference in two independent proportions. RESULTS: No differences were observed between gender, age and level of ID of service users based on their place of residence. But more people from an ethnic minority background were living in urban areas than rural areas. No differences were observed in the overall prevalence of mental illness by place of residence. However, the results showed that ASD was more common in people living in rural areas. CONCLUSIONS: We found these results surprising and at odds with the majority of studies carried out in the general population and propose several reasons for the differences found. We believe that the results and further studies in this area will help inform health service provision for those with ID who live in different geographical areas.

BACKGROUND: A number of studies have explored doctors' views and experiences of cardiopulmonary resuscitation (CPR), but to our knowledge there has been no research to identify the information that doctors take into account when they make decisions about CPR. PURPOSE OF STUDY: To investigate factors that influence decisions about CPR. STUDY DESIGN: Qualitative study involving six focus groups with 17 doctors and four medical students in Leicester, UK. RESULTS: Doctors and medical students considered a number of factors important when making decisions about CPR-namely, the patient's diagnosis, prognosis, age, quality of life, the opinions of doctors and other medical staff, and the wishes of patients and relevant others. The relative importance of each of these factors varied significantly and was influenced by the doctors' own beliefs and values. CONCLUSIONS: Doctors would benefit from greater support for their decision making in relation to resuscitation to reduce variability in clinical practice and to promote appropriate patient care. Identification of factors that influence doctors' individual beliefs, attitudes and values towards resuscitation and improvement in the quality of patient communication may help to guide policy in this area.

BACKGROUND: The study of premature deaths in people with intellectual disability (ID) has become the focus of recent policy initiatives in England. This is the first UK population-based study to explore cause-specific mortality in adults with ID compared with the general population. METHODS: Cause-specific standardised mortality ratios (SMRs) and exact 95% confidence intervals were calculated by age and sex for adults with moderate to profound ID living in the unitary authorities of Leicester, Leicestershire and Rutland, UK, between 1993 and 2006. Causes of death were also studied to determine how often ID and associated conditions, such as Down syndrome, were mentioned. RESULTS: A total of 503 (17% of population) adults with ID died during the 14-year study period (30 144 person-years). Relatively high cause-specific mortality was seen for deaths caused by congenital abnormalities (SMR = 8560), diseases of the nervous system and sense organs (SMR = 1630), mental disorders (other than dementia) (SMR = 1141) and bronchopneumonia (SMR = 647). Excess deaths were also seen for diseases of the genitourinary system or digestive system, cerebrovascular disease, other respiratory infections, dementia (in men only), other circulatory system diseases (in women only) and accidental deaths (in women only). Two-fifths (n = 204; 41%) of deaths recorded in adults with ID mentioned ID or an associated condition as a contributing cause of death. CONCLUSIONS: Strategies to reduce inequalities in people with ID need to focus on decreasing mortality from potentially preventable causes, such as respiratory infections, circulatory system diseases and accidental deaths. The lack of mention of ID on death certificates highlights the importance of effective record linkage and ID reporting in health and social care settings to facilitate the government's confidential inquiry into causes of death in this population.

BACKGROUND: Aggressive challenging behaviour is common in adults with intellectual disability (ID) in long-term care facilities. The government's commitment to the closure of all facilities in England has led to concerns over how to manage this behaviour in the community. The aim of this study was to assess changes in aggressive challenging behaviour and psychotropic drug use in adults with ID following resettlement using a person-centred approach. METHOD: The Modified Overt Aggression Scale was administered to carers of 49 adults with ID prior to discharge from a long-stay hospital and 6 months and 1 year after community resettlement. RESULTS: All areas of aggressive challenging behaviour reduced significantly between baseline and 6 months following resettlement (P < 0.001). This reduction remained (but did not decrease further) at 1-year follow-up. CONCLUSIONS: Further work is needed to evaluate the role of environmental setting on aggressive challenging behaviour in adults with ID.

BACKGROUND: UK policies aim to facilitate access to general psychiatric services for adults with intellectual disability (ID). If this is to be achieved, it is important to have a clear idea of the characteristics and proportion of people with ID who currently access specialist psychiatric services and the nature and extent of psychiatric disorders in this population. METHODS: A cross-sectional study was carried out on all adults with ID using specialist services in Leicestershire and Rutland, UK, between 2001 and 2006. Characteristics of individuals seen by psychiatric services and the nature and prevalence of psychiatric disorders were investigated. RESULTS: Of 2711 adults identified, 1244 (45.9%) accessed specialist psychiatric services at least once during the study period. Individuals attending psychiatric services were more likely to be older and to live in residential settings; they were less likely to be south Asian or to have mild/moderate ID. The prevalence of psychiatric disorders among the total study population was 33.8%; the most common disorders were behaviour disorder (19.8%) and autistic spectrum disorders (8.8%). Epilepsy was highly prevalent (60.8%) among those attending psychiatric services without a mental health diagnosis. Behaviour disorders and autistic spectrum disorders were more common in men and in adults with severe/profound ID, whereas schizophrenia and organic disorders were more common in women and in adults with mild/moderate ID. Depression was also more common in women with ID. CONCLUSIONS: Psychiatric disorders and specialist health problems are common among adults with ID and the profile of psychiatric disorders differs from that found in general psychiatry. Close collaboration between general and specialist service providers is needed if the current move towards use of general psychiatric services in this population is to be achieved. The measures should include a clear care pathway for people with ID and mental health problems to facilitate the smooth transfer of patients between specialist and generic mental health services and arrangements for joint working where input from both services is required. The commissioning framework for such processes should be in place with appropriate pooling of resources.

BACKGROUND: Previous studies of weight problems in adults with intellectual disability (ID) have generally been small or selective and given conflicting results. The objectives of our large-scale study were to identify inequalities in weight problems between adults with ID and the general adult population, and to investigate factors associated with obesity and underweight within the ID population. METHODS: We undertook a population-based prevalence study of 1119 adults with ID aged 20 and over on the Leicestershire Learning Disability Register who participated in a programme of universal health checks and home interviews with their carers. We performed a cross-sectional analysis of the register data and compared the observed and expected prevalences of body mass index categories in the ID and general populations using indirect standardisation for age. We used logistic regression to evaluate the association of a range of probable demographic, physical, mental and skills attributes with obesity and underweight. RESULTS: In those aged 25 and over, the standardised morbidity ratio (SMR) for obesity was 0.80 (95% CI 0.64-1.00) in men and 1.48 (95% CI 1.23-1.77) in women. The SMR for underweight was 8.44 (95% CI 6.52-10.82) in men and 2.35 (95% CI 1.72-3.19) in women. Among those aged 20 and over, crude prevalences were 20.7% for obesity, 28.0% for overweight, 32.7% for normal weight and 18.6% for underweight. Obesity was associated with living independently/with family, ability to feed/drink unaided, being female, hypertension, Down syndrome and the absence of cerebral palsy. Underweight was associated with younger age, absence of Down syndrome and not taking medication. CONCLUSION: Obesity in women and underweight in both men and women was more common in adults with ID than in the general population after controlling for differences in the age distributions between the two populations. The associated factors suggest opportunities for targeting high-risk groups within the ID population for lifestyle and behaviour modification.

BACKGROUND: People with intellectual disability (ID) experience a variety of health inequalities compared with the general population including higher mortality rates. This is the first UK population-based study to measure the extent of excess mortality in people with ID compared with the general population. METHOD: Indirectly standardized all-cause and disease mortality ratios (SMRs) and exact Poisson confidence intervals were calculated by age and sex for all adults, aged 20 years or over, with moderate to profound ID living in Leicestershire and Rutland, UK, between 1993 and 2005. The general population of Leicestershire and Rutland, which has a population of approximately 700,000 individuals in this age range, was used for comparison. To explore differences within the study population, overall SMRs were also calculated by presence of Down syndrome and last place of residence (city or county). RESULTS: Of 2436 adults identified, 409 (17%) died during 23,000 person-years of follow-up. Both all-cause and disease-specific mortality were around three times higher than the general population but varied considerably with age. The largest differences were observed in people in their twenties, where all-cause mortality was almost nine times higher in men (SMR=883; 95% CI=560-1325) and more than 17 times higher in women (SMR=1722; 95% CI=964-2840). At a particular disadvantage were people with Down syndrome and women with ID living in the city. CONCLUSIONS: The relatively high SMRs observed in young people and in women, particularly those living in inner city areas and with Down syndrome, deserve further investigation for possible explanations, including socio-economic factors.

BACKGROUND: Many people with learning disabilities (LD) show aggressive behaviour, but the extent of the problem and its associated factors and effects are unclear. METHODS: A cross-sectional analysis was carried out using interview data from 3065 adults with LD on the Leicestershire LD Register. Physical aggression towards others was defined as carers reporting frequent (more than three times per week) and/or severe episodes. Individuals with and without aggression were compared using multiple logistic regression models for potential physical and psychological factors. RESULTS: Carers reported that 443 (14%) of adults were physically aggressive towards others. Men (P = 0.001), younger individuals (P < 0.001), people with more severe LD (P < 0.001) and those in institutional settings (P < 0.001) had a significantly higher prevalence of physical aggression. People with Down syndrome had a lower prevalence of physical aggression (P < 0.001). After adjustment, we found no relationship between aggression and the presence of epilepsy or autism. Among psychological factors, symptoms of frustration (P < 0.001) and mood swings (P < 0.001) were associated with higher levels of aggression. Failure to cope among carers was reported by 14% overall: 42% of people caring for adults with aggression said they were unable to cope compared with 10% of those caring for adults without aggression. CONCLUSIONS: Physical aggression towards other people presents a significant challenge to carers of adults with LD. Further research is needed to identify aetiological factors with a view to finding effective interventions to reduce, and improve management of, this behaviour.

Seroconversion illness is known to be associated with more rapid HIV disease progression. However, symptoms are often subjective and prone to recall bias. We describe symptoms reported as seroconversion illness and examine the relationship between illness, HIV test interval (time between antibody-negative and anibody-positive test dates) and the effect of both on time to AIDS from seroconversion. We used a Cox model, adjusting for age, sex, exposure group and year of estimated seroconversion. Of 1820 individuals, information on seroconversion illness was available for 1244 of whom 423 (34%) reported symptomatic seroconversion. Persons with a short test interval (< or = 2 months) were significantly more likely to report an illness than people with a longer interval (OR 6.76, 95% CI 4.75-9.62). Time to AIDS was significantly faster (P = 0.01) in those with a short test interval. The HIV test interval is a useful replacement for information on seroconversion illness in studies of HIV disease progression.

BACKGROUND: Antidepressants are commonly prescribed by general practitioners as treatment for depression. Controversy exists as to the effectiveness in everyday use of the older tricyclic antidepressants (TCAs) when compared to the newer selective serotonin reuptake inhibitors (SSRIs). AIM: To investigate the patterns of current prescribing of antidepressants for the treatment of depression and compare TCAs with the newer SSRIs. METHOD: The study population was patients attending 151 computerised general practices from throughout the United Kingdom between 1991 and 1996. Patients with new prescriptions for antidepressants and a diagnosis of depression were identified. Age and gender distributions, prescribed doses and drop-out rates were investigated. RESULTS: During the study period 9.8% of patients received a prescription for an antidepressant, there was a 40% increase in the prescribing rate of TCAs and a 460% increase in SSRI prescribing. TCAs were initially prescribed in sub-therapeutic doses. More than 50% of patients ceased taking their antidepressants within 6 weeks of starting treatment. Fluoxetine and paroxetine were more likely to be prescribed for a therapeutic period than were other antidepressants. CONCLUSIONS: General practitioners should prescribe a therapeutic dose of antidepressant for a recognised therapeutic period to ensure that patients with depression receive the most effective treatment.

AIMS: In October 1995 in response to the results of three studies, the Committee on the Safety of Medicines advised doctors and pharmacists that oral contraceptives containing desogestrel (DSG) and gestodene (GST) were associated with around a two-fold increase in the risk of thromboembolism compared with those containing other progestogens. The objective of this study was to estimate the risk of idiopathic venous thromboembolic disease (VTE) in users of combined oral contraceptives (COCs), to compare the risk between formulations and to examine the effect of using age banding as opposed to matching by exact year of birth. METHODS: A nested case control study was conducted using the General Practice Research Database. Women with a VTE event recorded between 1992 and 1997, who were treated with an anticoagulant, from consideration of their prescription records were likely to have been using a COC prescription on the day of the event and also had no exclusion factors, were deemed cases. For comparison with the previous studies, two nested case control studies were undertaken. Study 1 used controls matched by practice and year of birth. Study 2 used controls matched by practice and within 5 years age bands. RESULTS: We found an incidence of idiopathic VTE amongst users of combined oral contraceptives of 3.8 per 10 000 exposed women years. Incidence rates increased markedly after 35 years of age. The nested case-control study using controls matched by year of birth showed no significant difference in risk between the major COC formulations. With levonorgestrel (LNG) 150 microgram and ethinyloestradiol (EE) 30 microgram as the reference, the adjusted ORs for GST 75 microgram and EE 30 microgram was 1.3 (95% CI 0.8, 2.1), for DSG 150 microgram and EE 30 microgram it was 1.0 (95% CI 0.7, 1.7) and for DSG 150 microgram and EE 20 microgram it was 0.8 (95% CI 0.4, 1.6). Using less rigorous matching criteria, matching controls to cases within 5 years age bands, the ORs increased. When a mixed group of COCs, characterized by having LNG as the progestogen component was used as the reference category, there was an elevation in the ORs for the newer products. We found a significant association between idiopathic VTE and current smoking (OR 2.0 (1.4, 2.7)), BMI over 35 (OR 3.8 (1.8, 8.0)) and asthma (OR 1.9 (1.3, 2.9)). The OR for women who had proxy evidence of general ill health (indicated by the number of prescriptions issued) was 2.2 (1.7, 3.7). CONCLUSIONS: The results of this study indicate that a number of the characteristics of the women taking COCs affect the risk of VTE. There is no evidence to support the hypothesis that there is any difference in risk between COC formulations containing under 50 microg ethinyloestradiol.

STUDY OBJECTIVE: To investigate whether there has been an increase of venous thromboembolism (VTE) mortality in European countries, concurrent with the replacement of second generation by third generation combined oral contraceptives (COCs). Such an increase has been predicted, and reportedly detected, because published studies have detected an increased incidence of VTE associated with third generation rather than second generation COC use. DESIGN: Data were collected on population and annual VTE mortality in women 15-34 and 35-49 years old, and on second and third generation COC sales, from 1981 to 1994 in 13 European countries. Data from the seven most populous countries were analysed by linear regression of annual VTE mortality, in the 15-34 and 15-49 age groups, with respect to calculated total and third generation COC use rates, and the regression coefficients used to estimate mortality differences between second generation users and non-users and between third and second generation users, respectively. MAIN RESULTS: The estimated mortality differences in all seven countries had confidence intervals wide enough to contain both zero and the excess mortalities expected from the results of published studies. This was true both for the mortality difference between third and second generation COC users and for that between second generation users and COC non-users. CONCLUSIONS: Mortality differences of the size expected from the published studies cannot be measured using annual national VTE mortality and COC sales data alone, because of residual interannual variation in VTE mortality, and possibly confounding between rising third generation market share and total COC use.

In this study, undertaken to identify the cause of allergy in several upholstery workers in a furniture factory, the workers were handling several different materials, including glue, silicone spray, upholstery fabrics, and felt. Radio-allergo-sorbent test (RAST) assays showed that sera from sensitised workers contained specific IgE towards the felt; however, further investigations using RAST showed that the allergen was not the felt itself but a contaminant of the felt. The felt was manufactured from sacks, some of which had been used to store castor beans. The sera with raised IgE to the felt also had raised IgE to the castor bean extract. By means of RAST inhibition we confirmed that castor bean allergens in the felt were solely responsible for the raised IgE in the sera. The in-vitro RAST results were found to correlate well with the in-vivo pick tests and clinical symptoms.
