RESUMO
AIMS: To investigate whether the association of severe mental illness with Type 2 diabetes varies by ethnicity and age. METHODS: We conducted a cross-sectional analysis of data from an ethnically diverse sample of 588 408 individuals aged ≥18 years, registered to 98% of general practices (primary care) in London, UK. The outcome of interest was prevalent Type 2 diabetes. RESULTS: Relative to people without severe mental illness, the relative risk of Type 2 diabetes in people with severe mental illness was greatest in the youngest age groups. In the white British group the relative risks were 9.99 (95% CI 5.34, 18.69) in those aged 18-34 years, 2.89 (95% CI 2.43, 3.45) in those aged 35-54 years and 1.16 (95% CI 1.04, 1.30) in those aged ≥55 years, with similar trends across all ethnic minority groups. Additional adjustment for anti-psychotic prescriptions only marginally attenuated the associations. Assessment of estimated prevalence of Type 2 diabetes in severe mental illness by ethnicity (absolute measures of effect) indicated that the association between severe mental illness and Type 2 diabetes was more marked in ethnic minorities than in the white British group with severe mental illness, especially for Indian, Pakistani and Bangladeshi individuals with severe mental illness. CONCLUSIONS: The relative risk of Type 2 diabetes is elevated in younger populations. Most associations persisted despite adjustment for anti-psychotic prescriptions. Ethnic minority groups had a higher prevalence of Type 2 diabetes in the presence of severe mental illness. Future research and policy, particularly with respect to screening and clinical care for Type 2 diabetes in populations with severe mental illness, should take these findings into account.

OBJECTIVE: To contrast the prevalence of mild cognitive impairment (MCI) as diagnosed using DSM-5 criteria (DSM5-MCI) with MCI as diagnosed using Petersen's criteria (P-MCI) and to explore the association of both with non-cognitive psychopathological symptoms (NCPS). METHOD: A two-phase epidemiological screening was implemented in a population-based sample of individuals aged 55+ (n = 4803). The Geriatric Mental State (GMS) was the main psychopathological instrument used, and AGECAT was used to make psychiatric diagnoses. Research psychiatrists diagnosed DSM5-MCI and P-MCI using operational criteria. Logistic regression models were then used to investigate the association of MCI with anxiety and depression and with NCPS. RESULTS: Weighted prevalence of DSM5-MCI and P-MCI was, respectively, 3.72% and 7.93% for the aged 65+. NCPS were common in both MCI categories, but negative-type symptoms such as 'anergia' and 'observed slowness' were considerably more frequent among persons with DSM5-MCI. Anxiety and depression diagnostic categories were associated with both P-MCI and DSM5-MCI, but affective-type symptoms were mainly associated with P-MCI. Some negative-type symptoms were inversely associated with P-MCI, and no association was observed with DSM5-MCI. CONCLUSION: The prevalence of DSM5-MCI was half that of P-MCI. Negative-type NCPS were more frequently and typically associated with DSM5-MCI.

BACKGROUND: Worldwide, the Irish diaspora experience health inequalities persisting across generations. The present study sought to establish the prevalence of psychological morbidity in the children of migrant parents from Ireland, and reasons for differences. METHODS: Data from two British birth cohorts were used for analysis. Each surveyed 17 000 babies born in one week in 1958 and 1970 and followed up through childhood. Validated scales assessed psychological health. RESULTS: Relative to the rest of the cohort, second-generation Irish children grew up in material hardship and showed greater psychological problems at ages 7, 11 (1958 cohort) and 16 (both cohorts). Adjusting for material adversity and maternal psychological distress markedly reduced differences. Relative to non-Irish parents, Irish-born parents were more likely to report chronic health problems (odds ratio [OR]: 1.29; 95% confidence interval [CI]: 1.08-1.54), and Irish-born mothers were more likely to be psychologically distressed (OR: 1.44; 95% CI: 1.13-1.84, when child was 10). Effect sizes diminished once material adversity was taken into account. CONCLUSIONS: Second-generation Irish children experienced high levels of psychological morbidity, but this was accounted for through adverse material circumstances in childhood and psychological distress in parents. Public health initiatives focusing on settlement experiences may reduce health inequalities in migrant children.

BACKGROUND: It is not known whether social support modifies the association between depression and impairment or disability in older people from developing countries in Asia. METHOD: We used a Thai version of the EURO-D scale to measure depression in 1104 Thai rural community-dwelling parents aged 60 years. These were all those providing data on depression who were recruited as part of a study of older adults with at least one living child (biological, stepchild or adopted child). Logistic regression modelling was used to determine: (a) whether impairment, disability and social support deficits were associated with depression; (b) whether social support modified this association. RESULTS: There were strong graded relationships between impairment, disability, social support deficits and EURO-D caseness. Level of impairment, but not disability, interacted with poor social support in that depression was especially likely in those who had more physical impairments as well as one or more social support deficits (p value for interaction=0.018), even after full adjustment. CONCLUSIONS: Social support is important in reducing the association between physical impairment and depression in Thai older adults, especially for those with a large number of impairments. Enhancing social support as well as improving healthcare and disability facilities should be emphasized in interventions to prevent depression in older adults.

OBJECTIVE: Clinical experience and recent population studies suggest that psychopathological, non-cognitive symptoms are both frequent and relevant in dementia. METHOD: A representative community sample (n = 4,803 individuals, 55 + years) was interviewed in a two-phase design. The Geriatric Mental Sate (GMS) was used for assessment and cases were diagnosed according to DSM-IV-TR criteria. RESULTS: The prevalence of non-cognitive symptoms (1 + symptoms) in cases of dementia (n = 223) was 90.1%, and negative-type symptoms were most frequently found. A GMS 'apathy-related symptom cluster' (anergia, restriction of activities and anhedonia) was significantly more frequent in the demented (55.6%) than in non-cases (0.7%; specificity = 99.2%). In both dementia of Alzheimer's type and vascular dementia, number of symptoms tended to be inversely related to severity of dementia, but psychopathological profiles differed. CONCLUSION: Non-cognitive, negative-type symptoms are very frequent in cases of dementia living in the community. They have powerful specificity in the distinction with non-cases, and might change current concepts of dementia.

BACKGROUND: Epidemiological studies have shown that depression is common in institutional settings. However, the symptomatology of depression in this group has not been compared to those living in the community. AIMS: To estimate the prevalence of depression and depressive symptomatology in participants living in institutions and compare these to people living in other settings. METHOD: The Medical Research Council Cognitive Function and Ageing Study (MRC CFAS) is a population-based cohort comprising 13,004 individuals aged 65 and above, from five sites across England and Wales. Following screening, a stratified random sub-sample of 2,640 participants received the Geriatric Mental State (GMS) examination of whom 340 resided in institutions. Diagnoses of depression were made using the Automated Geriatric Examination for Computer-assisted Taxonomy system (AGECAT). RESULTS: The prevalence of depression in those living in institutions was 27.1% (95% CI 17.8-36.3) compared to 9.3% (95% CI 7.8-10.9) in those living at home. Symptoms relating to depressed mood, severity of illness (e.g. wishing to be dead, future looking bleak) and some non-specific symptoms were more common in those living in residential homes. Depression was significantly associated with younger age (P = 0.002) and high functional disability (P = 0.009) in those living in institutions. CONCLUSIONS: Consistent with previous estimates, depression was highly prevalent in institutions, particularly in younger individuals with severe functional impairment. Those in institutions report considerably more symptoms of depression. Finding interventions which address these symptoms might improve quality of life for people in institutions, irrespective of formal diagnoses.

BACKGROUND: Associations between physical health and depression are consistent across cultures among adults up to 65 years of age. In later life, the impact of physical health on depression is much more substantial and may depend on sociocultural factors. AIMS: To examine cross-national differences in the association between physical health and depressive symptoms in elderly people across western Europe. METHOD: Fourteen community-based studies on depression in later life in nine western European countries contributed to a total study sample of 22 570 respondents aged 65 years and older. Measures were harmonized for depressive symptoms (EURO-D scale), functional limitations and chronic physical conditions. RESULTS: In the majority of the participating samples, the association of depressive symptoms with functional disability was stronger than with chronic physical conditions. Associations were slightly more pronounced in the UK and Ireland. CONCLUSIONS: The association between physical health and depressive symptoms in later life is consistent across western Europe.

OBJECTIVE: to measure the cost-effectiveness of an early discharge and rehabilitation service (EDRS) in Nottingham, UK. DESIGN: data were collected during a randomised controlled trial. METHODS: cost and cost-effectiveness analyses were conducted from the perspective of service providers (health and social services) over a period of 12 months. Resource variables included were the EDRS intervention, the initial acute hospital admission (from randomisation), readmission to hospital, hospital outpatient visits, stays in nursing and residential homes, general practitioner contact, community health services and social services. The effectiveness measure was the EuroQol EQ-5D score, from which quality-adjusted life years (QALY) were calculated. Cost-effectiveness was calculated as cost per QALY gained. RESULTS: at 12 months the mean untransformed total cost for the EDRS was 8,361 pound sterling compared to 10,088 pound sterling for usual care, a saving of 1,727 pound sterling (P = 0.05). Cost-effectiveness acceptability curves showed a high probability that the EDRS was cost effective across a range of monetary values for a QALY. CONCLUSIONS: the Nottingham EDRS was likely to be more cost effective than usual care.

OBJECTIVES: To test the effects of a home-based educational intervention in reducing the incidence and the risk of falls and pressure sores in adults with progressive neurological conditions. DESIGN: Randomized controlled trial with 12 months follow-up. SETTING: Participants' homes in the City of Nottingham. PARTICIPANTS: One hundred and fourteen people with progressive neurological conditions recruited from general practices in Nottingham, including 53 with Parkinson's disease and 45 with multiple sclerosis. INTERVENTIONS: In the education group (EG), baseline data were reviewed by an expert panel which advised on actions most likely to promote each individual's physical, social and psychological well-being. An occupational therapist (OT) then visited EG participants to provide education and information and to discuss a personalized 12-month health action plan. The comparison group (CoG) received standardized printed information delivered to their home. MAIN MEASURES: Numbers of participants reporting falls and skin sores at two-monthly phone calls during the follow-up period of 12 months. RESULTS: The EG reported significantly more falls during the follow-up period and at 12 months (adjusted odds ratio 2.83 (95% CI 1.07-7.47), p=0.036) and significantly more skin sores (adjusted odds ratio 12.74 (95% CI 1.14-142.6), p =0.039) than the CoG. There was no difference between CoG and EG in the Nottingham Extended Activities of Daily Living score, but EG patients showed a significant rise in this score over the study period of 1.62 (95% CI 0.69-2.55, p=0.002). CONCLUSIONS: Our findings provide evidence that education for people with progressive neurological conditions can have negative effects.

BACKGROUND: Contrary to early case-control studies that suggested smoking protects against Alzheimer disease (AD), recent prospective studies have shown that elderly who smoke may be at increased risk for dementia. OBJECTIVE: To examine prospectively the effect of smoking on cognition in nondemented elderly. METHOD: In a multicenter cohort, the European Community Concerted Action Epidemiology of Dementia (EURODEM), including the Odense, Personnes Agées Quid (Paquid), Rotterdam, and Medical Research Council: Ageing in Liverpool Project-Health Aspects (MRC ALPHA) Studies, 17,610 persons aged 65 and over were screened and examined for dementia. After an average 2.3 years of follow-up, 11,003 nondemented participants were retested. Excluding incident dementia cases and those without baseline information on smoking gave an analytical sample of 9,209 persons. Average yearly decline in Mini-Mental State Examination (MMSE) score was compared among groups, adjusting for age, sex, baseline MMSE, education, type of residence, and history of myocardial infarction or stroke. RESULTS: MMSE score of persons who never smoked on average declined 0.03 point/year. The adjusted decline of former smokers was 0.03 point greater and of current smokers 0.13 point greater than never smokers (p < 0.001). Higher rates of decline by smoking were found in men and women, persons with and without family history of dementia, and in three of four participating studies. Higher cigarette pack-year exposure was correlated with a significantly higher rate of decline. CONCLUSION: Smoking may accelerate cognitive decline in nondemented elderly.

The Geriatric Mental State Examination (GMS) is now established as one of the most commonly used mental health assessments for older people. Its strengths lie in extensive validity studies, high inter-rater reliability, accessibility to trained raters, irrespective of professional background and its continual evolution and adaptation. Its computerisation, association with supplementary instruments and support by a diagnostic algorithm provides a comprehensive diagnostic system and syndrome profile for each subject. The instrument has been validated against most major diagnostic systems and has been used as outcome measures in intervention studies. It has been translated into numerous languages and validated as a diagnostic instrument in various cultures. Such studies have exposed weaknesses, including the over diagnoses of organic states in populations with poorly developed education. On-going studies continue to address these issues, providing a culture sensitive instrument enabling unique trans-cultural research in a relatively under-researched field.

OBJECTIVE: To provide a computerised method of diagnosing organic brain syndrome from history data without the use of mental state data. METHODS: Interview dataset from participants in a community study of the incidence of dementia was used to form a training sample and validation sample. The algorithm was developed on the training sample and tested on the validation sample. RESULTS: Performance in the training and validation samples was very similar. The algorithm shows monotonically increasing probability of being diagnosed with dementia as a function of the proposed level of diagnostic confidence. At the proposed cut point it has sensitivity 94% and specificity 84% for detecting concurrent psychiatrist's diagnosis of dementia. CONCLUSIONS: The method provides a good agreement with psychiatrist's diagnosis, and the results in the validation sample show little shrinkage. The method will prove useful in studies where it has proved impossible to collect mental state information on all the study participants.

BACKGROUND: No recent attempt has been made to synthesise information on mortality and dementia despite the theoretical and practical interest in the topic. Our objective was to estimate the influence on mortality of cognitive impairment and dementia. METHODS: Data sources were Medline, Embase, personal files and colleagues' records. Studies were considered if they included a majority of persons aged 65 and over at baseline either drawn from a total community sample or drawn from a random sample from the community. Samples from health care facilities were excluded. The search located 68 community studies. Effect sizes were extracted from the studies and if they were not included in the published studies, effect sizes were calculated where possible: this was possible for 23 studies of cognitive impairment and 32 of dementia. No attempt was made to contact authors for missing data. RESULTS: For the studies of cognitive impairment Fisher's method (a vote counting method), gave a p-value (from eight studies) of 0.00001. For studies of dementia, age-adjusted confidence intervals (CI) were pooled (odds ratio (OR) 2.63 with 95% CI 2.17 to 3.21 from six studies). CONCLUSIONS: Levels of cognitive impairment commonly found in community studies give rise to an increased risk of mortality, and this appears to be true even for quite mild levels of impairment. The analysis confirms the increased risk of mortality for dementia, but reveals a dearth of information on the causes of the excess mortality and on possible effect modification by age, dementia subtype or other variables.

One hundred and fourteen consecutive patients with early breast cancer were entered into a study on the psychological effects of involvement in treatment choice. All women were offered counselling throughout. One group of women (n = 34), were advised to undergo mastectomy, due to the nature or position of the tumour. These women fared less well psychologically when compared on a battery of measures, before and after surgery, with women who were involved in choosing their own treatment (n = 80). The latter group itself was randomly allocated into two groups for taking explicit responsibility for treatment choice, using a double-blind procedure. These were a Patient Decision Group (n = 41) and a Surgeon Decision Group (n = 39). Results support the hypothesis that over and above the benefits of receiving their preferred treatment, women can further benefit from taking explicit responsibility for their treatment choice.

BACKGROUND: No recent attempt has been made to synthesize information on mortality and depression despite the theoretical and practical interest in the topic. Our objective was to estimate in the older population the influence on mortality of depression and depressive symptoms. METHODS: Data sources were: Medline, Embase, personal files and colleagues' records. Studies were considered if they included a majority of persons aged > or = 65 years at baseline either drawn from a total community sample or drawn from a random sample from the community. Samples from healthcare facilities were excluded. Effect sizes were extracted from the papers; if they were not included in the published papers, effect sizes were calculated if possible. No attempt was made to contact authors for missing data. RESULTS: We found 21 reports on 23 cohorts using depression diagnosis. For 15 of these, odds ratios were pooled using the Greenland method based on confidence intervals (CIs), giving an estimated odds ratio for mortality with depression of 1.73 (95% CI 1.53 to 1.95). A fixed effects meta-regression of these studies suggested that longer follow-up predicted smaller effect sizes (log odds ratios -0.096 per year (95% CI -0.179 to -0.014)). There is a weak suggestion of a reduced effect of depression on mortality for women. We were unable to pool effect sizes from the 17 studies using symptom totals and scales, or from eight studies of specific symptoms. CONCLUSIONS: The studies show that diagnosed depression in community-resident older people is associated with increased mortality. The picture for sex differences is still unclear.

OBJECTIVES: To describe the patterns of self-reported medication use, including both prescription and non-prescription drugs, for older people in five areas in England and Wales, and to identify the effects of socio-demographic features on medication use. DESIGN: A cross-sectional survey on population random samples of people aged 65 and over. The survey is a part of the screening interviews at the first stage of the Medical Research Council Cognitive Function and Ageing Study (MRC CFAS) carried out between 1991 and 1994. The sample was stratified to provide equal numbers in the 65-74 years and 75 years and over age groups. SETTING: Three urban (Newcastle, Nottingham and Oxford) and two rural (Cambridgeshire and Gwynedd) centres. Older people living in both the general community and institutions were included. PARTICIPANTS: 12489 older people whose medication data were collected among the 13009 participants of the CFAS, of which the participation rate is 80%. RESULTS: Overall prevalence of medication use was 75% (95% confidence interval 74-76%) for people aged 65-74 and 84% (83-85%) for people aged 75 and over, with a mean number of 2.03 (standard deviation 1.95) and 2.47 (2.02) drugs reported per respondent in each group, respectively. Concurrent use of five or more drugs (polypharmacy) was found in 11% (10-12%) of people in the 65-74 age group and in 15% (14-16%) in the 75 and over age group. People aged 75 and over were more likely to be taking at least one drug than people aged 65-74 (OR=1.69, 1.54-1.85), and women were more likely to be so compared with men (OR=1.43, 1.30-1.56). Centre variation was found but none of the centres consistently showed higher or lower usage of medications across the major drug categories. People living in institutions were more likely to be taking gastrointestinal drugs, central nervous system drugs and experience polypharmacy. The use of respiratory and central nervous system drugs (except hypnotics and anxiolytics) increased in lower social class and decreased in people attending full-time education for 10 years or more. The use of haematology/dietetic drugs (85% of which were vitamin and mineral preparations) decreased in lower social class. CONCLUSION: This study provides representative estimates of medication usage among older people in England and Wales and identified associated factors and regional variations for medication use in a category-specific manner. The findings, suggesting the existence of centre variation and the association between type of accommodation, social class and medication use warrant further investigation.

OBJECTIVE: To evaluate the effects of leisure therapy and conventional occupational therapy (OT) on the mood, leisure participation and independence in activities of daily living (ADL) of stroke patients 6 and 12 months after hospital discharge. DESIGN: Multicentre randomized controlled trial. SETTING AND PARTICIPANTS: Four hundred and sixty-six stroke patients from five UK centres. MAIN OUTCOME MEASURES: The General Health Questionnaire (12 item), the Nottingham Extended ADL Scale and the Nottingham Leisure Questionnaire, assessed by post, with telephone clarification. RESULTS: Four hundred and forty (94%) and 426 (91%) subjects were alive at 6 and 12 months, respectively. Three hundred and seventy-four (85% of survivors) and 311 (78% of survivors) responded at 6 and 12 month follow-up respectively. At six months and compared to the control group, those allocated to leisure therapy had nonsignificantly better GHQ scores (-1.2: 95% CI -2.9, +0.5), leisure scores (+0.7, 95% CI -1.1, +2.5) and Extended ADL scores (+0.4: 95% CI -3.8, +4.5): the ADL group had nonsignificantly better GHQ scores (-0.1: 95% CI -1.8, +1.7) and Extended ADL scores (+1.4: 95% CI -2.9, +5.6) and nonsignificantly worse leisure scores (-0.3: 95% CI -2.1, +1.6). The results at 12 months were similar. CONCLUSION: In contrast to the findings of previous smaller trials, neither of the additional OT treatments showed a clear beneficial effect on mood, leisure activity or independence in ADL measured at 6 or 12 months.

The hypothesis that a low educational level increases the risk for Alzheimer's disease remains controversial. The authors studied the association of years of schooling with the risk for incident dementia and Alzheimer's disease by using pooled data from four European population-based follow-up studies. Dementia cases were identified in a two-stage procedure that included a detailed diagnostic assessment of screen-positive subjects. Dementia and Alzheimer's disease were diagnosed by using international research criteria. Educational level was categorized by years of schooling as low (< or =7), middle (8-11), or high (> or =12). Relative risks (95% confidence intervals) were estimated by using Poisson regression, adjusting for age, sex, study center, smoking status, and self-reported myocardial infarction and stroke. There were 493 (328) incident cases of dementia (Alzheimer's disease) and 28,061 (27,839) person-years of follow-up. Compared with women with a high level of education, those with low and middle levels of education had 4.3 (95% confidence interval: 1.5, 11.9) and 2.6 (95% confidence interval: 1.0, 7.1) times increased risks, respectively, for Alzheimer's disease. The risk estimates for men were close to 1.0. Finding an association of education with Alzheimer's disease for women only raises the possibility that unmeasured confounding explains the previously reported increased risk for Alzheimer's disease for persons with low levels of education.

OBJECTIVE: To study the difference in risk for dementing diseases between men and women. BACKGROUND: Previous studies suggest women have a higher risk for dementia than men. However, these studies include small sample sizes, particularly in the older age groups, when the incidence of dementia is highest. METHODS: Pooled analysis of four population-based prospective cohort studies was performed. The sample included persons 65 years and older, 528 incident cases of dementia, and 28,768 person-years of follow-up. Incident cases were identified in a two-stage procedure in which the total cohort was screened for cognitive impairment, and screen positives underwent detailed diagnostic assessment. Dementia and main subtypes of AD and vascular dementia were diagnosed according to internationally accepted guidelines. Sex- and age-specific incidence rates, and relative and cumulative risks for total dementia, AD, and vascular dementia were calculated using log linear analysis and Poisson regression. RESULTS: There were significant gender differences in the incidence of AD after age 85 years. At 90 years of age, the rate was 81.7 (95% CI, 63.8 to 104.7) in women and 24.0 (95% CI, 10.3 to 55.6) in men. There were no gender differences in rates or risk for vascular dementia. The cumulative risk for 65-year-old women to develop AD at the age of 95 years was 0.22 compared with 0.09 for men. The cumulative risk for developing vascular dementia at the age of 95 years was similar for men and women (0.04). CONCLUSION: Compared with men, women have an increased risk for AD. There are no gender differences in risk for vascular dementia.
