Asthma and COPD management of patients with intellectual disabilities in general practice.

People with intellectual disabilities experience overall poorer health and healthcare access than the general population. It is largely unknown how this applies to asthma and chronic obstructive pulmonary disease (COPD) management by general practitioners (GPs). In a 10-year retrospective matched cohort study, n = 34,429, we examined year prevalence of asthma and COPD in adult patients with and without intellectual disabilities and potential differences in the delivery of asthma and COPD disease management activities in Dutch general practices (2010-2019). We collected information on patient characteristics, comorbidity, consultation patterns, use and outcomes of asthma/COPD control questionnaires, spirometry measurement, pulmonology referrals, and prescribed medication. Asthma patients with intellectual disabilities suffered more frequently from obesity (53.2% vs. 39.5% without intellectual disabilities), and both asthma and COPD patients with intellectual disabilities were more frequently current smokers (45.2% vs. 22.1% without intellectual disabilities, and 76.6% vs. 51.4% without intellectual disabilities, respectively). Also, a statistically significant larger number of asthma patients with intellectual disabilities were prescribed antibiotics (69.9% vs. 54.5%). COPD patients with intellectual disabilities, compared with matched controls without intellectual disabilities, received significantly more often either no COPD-related practice consultation at all (respectively 20.8% vs. 8.5%, p = 0.004) or a large number of practice consultations (>31 consultations, respectively 16.7% vs. 5.3%, p = 0.004). For asthma, there was no statistical difference between patients with or without intellectual disabilities regarding the number and type of consultations. The asthma year point prevalence in patients with intellectual disabilities was, from 2014 onward, significantly higher, and in 2019 was 8.7% vs. 6.0% for people without intellectual disabilities. For COPD, it was comparable in both groups. Both asthma and COPD patients with intellectual disabilities appeared considerably younger in age than patients without intellectual disabilities. Our findings warrant further research into the causes of the differences found for asthma and COPD and whether they also infer differences in the quality or the effectiveness of GP disease management, especially for young adults with intellectual disabilities.

All-cause and cause-specific mortality among people with and without intellectual disabilities during the COVID-19 pandemic in the Netherlands: a population-based cohort study.

BACKGROUND: Although high rates of COVID-19-related deaths have been reported for people with intellectual disabilities during the first 2 years of the pandemic, it is unknown to what extent the pandemic has impacted existing mortality disparities for people with intellectual disabilities. In this study, we linked a Dutch population-based cohort that contained information about intellectual disability statuses with the national mortality registry to analyse both cause-specific and all-cause mortality in people with and without intellectual disabilities, and to make comparisons with pre-pandemic mortality patterns. METHODS: This population-based cohort study used a pre-existing cohort that included the entire Dutch adult population (everyone aged ≥18 years) on Jan 1, 2015, and identified people with presumed intellectual disabilities through data linkage. For all individuals within the cohort who died up to and including Dec 31, 2021, mortality data were obtained from the Dutch mortality register. Therefore, for each individual in the cohort, information was available about demographics (sex and date of birth), indicators of intellectual disability, if any, based on chronic care and (social) services use, and in case of death, the date and underlying cause of death. We compared the first 2 years of the COVID-19 pandemic (2020 and 2021) with the pre-pandemic period (2015-19). The primary outcomes in this study were all-cause and cause-specific mortality. We calculated rates of death and generated hazard ratios (HRs) using Cox regression analysis. FINDINGS: At the start of follow-up in 2015, 187 149 Dutch adults with indicators of intellectual disability were enrolled and 12·6 million adults from the general population were included. Mortality from COVID-19 was significantly higher in the population with intellectual disabilities than in the general population (HR 4·92, 95% CI 4·58-5·29), with a particularly large disparity at younger ages that declined with increasing age. The overall mortality disparity during the COVID-19 pandemic (HR 3·38, 95% CI 3·29-3·47) was wider than before the pandemic (3·23, 3·17-3·29). For five disease groups (neoplasms; mental, behavioural, and nervous system; circulatory system; external causes; and other natural causes) higher mortality rates were observed in the population with intellectual disabilities during the pandemic than before the pandemic, and the pre-pandemic to during the pandemic difference in mortality rates was greater in the population with intellectual disabilities than in the general population, although relative mortality risks for most other causes remained within similar ranges compared with pre-pandemic years. INTERPRETATION: The impact of the COVID-19 pandemic on people with intellectual disabilities has been greater than reflected by COVID-19-related deaths alone. Not only was the mortality risk from COVID-19 higher in people with intellectual disabilities than in the general population, but overall mortality disparities were also further exacerbated during the first 2 years of the pandemic. For disability-inclusive future pandemic preparedness this excess mortality risk for people with intellectual disabilities should be addressed.

Risk for Severe COVID-19 Outcomes among Persons with Intellectual Disabilities, the Netherlands.

The COVID-19 pandemic has disproportionately affected persons in long-term care, who often experience health disparities. To delineate the COVID-19 disease burden among persons with intellectual disabilities, we prospectively collected data from 36 care facilities for 3 pandemic waves during March 2020-May 2021. We included outcomes for 2,586 clients with PCR-confirmed SARS-CoV-2 infection, among whom 161 had severe illness and 99 died. During the first 2 pandemic waves, infection among persons with intellectual disabilities reflected patterns observed in the general population, but case-fatality rates for persons with intellectual disabilities were 3.5 times higher and were elevated among those >40 years of age. Severe outcomes were associated with older age, having Down syndrome, and having >1 concurrent condition. Our study highlights the disproportionate COVID-19 disease burden among persons with intellectual disabilities and the need for disability-inclusive research and policymaking to inform disease surveillance and public health policies for this population.

Chronic diseases and comorbidities in adults with and without intellectual disabilities: comparative cross-sectional study in Dutch general practice.

BACKGROUND: Chronic disease and comorbidity patterns in people with intellectual disabilities (ID) are more complex than in the general population. However, incomplete understanding of these differences limits care providers in addressing them. OBJECTIVE: To compare chronic disease and comorbidity patterns in chronically ill patients with and without ID in Dutch general practice. METHODS: In this population-based study, a multi-regional primary care database of 2018 was combined with national population data to improve identification of adults with ID. Prevalence was calculated using Poisson regression to estimate prevalence ratios and 95% confidence intervals for the highest-impact chronic diseases (ischemic heart disease (IHD), cerebrovascular disease (CVD), diabetes mellitus (DM), and chronic obstructive pulmonary disease (COPD)) and comorbidities. RESULTS: Information from 18,114 people with ID and 1,093,995 people without ID was available. When considering age and sex, CVD (PR = 1.1), DM (PR = 1.6), and COPD (PR = 1.5) times more prevalent in people with than without ID. At younger age, people with ID more often had a chronic disease and multiple comorbidities. Males with ID most often had a chronic disease and multiple comorbidities. Comorbidities of circulatory nature were most common. CONCLUSIONS: This study identified a younger onset of chronic illness and a higher prevalence of multiple comorbidities among people with ID in general practice than those without ID. This underlines the complexity of people with ID and chronic diseases in general practice. As this study confirmed the earlier onset of chronic diseases and comorbidities, it is recommended to acknowledge these age differences when following chronic disease guidelines.

Cancer-related mortality among people with intellectual disabilities: A nationwide population-based cohort study.

BACKGROUND: Concerns have been raised about access to cancer screening and the timely receipt of cancer care for people with an intellectual disability (ID). However, knowledge about cancer mortality as a potential consequence of these disparities is still limited. This study, therefore, compared cancer-related mortality patterns between people with and without ID. METHODS: A historical cohort study (2015-2019) linked the Dutch adult population (approximately 12 million people with an ID prevalence of 1.45%) and mortality registries. Cancer-related mortality was identified by the underlying cause of death (according to the chapter on neoplasms in the International Classification of Diseases, Tenth Revision). Observed mortality and calculated age- and sex-standardized mortality ratios (SMRs) with 95% confidence intervals (CIs) were reported. RESULTS: There were 11,102 deaths in the ID population (21.7% cancer-related; n = 2408) and 730,405 deaths in the general population (31.2%; n = 228,120) available for analysis. Cancer was noted as the cause of death more often among people with ID in comparison with the general population (SMR, 1.48; 95% CI, 1.42-1.54), particularly in the young age groups. High-mortality cancers included cancers within the national screening program (SMRs, 1.43-1.94), digestive cancers (SMRs, 1.24-2.56), bladder cancer (SMR, 2.07; 95% CI, 1.61-2.54), and cancers of unknown primary (SMR, 2.48; 95% CI, 2.06-2.89). CONCLUSIONS: Cancer was reported as the cause of death approximately 1.5 times more often in people with ID compared with the general population. This mortality disparity may indicate adverse effects from inequalities in screening and cancer care experienced by people with ID. LAY SUMMARY: People with an intellectual disability (ID) may find it challenging to participate in cancer screening or to receive timely cancer care. To understand potential consequences in terms of mortality, this study compared cancer-related mortality between people with and without ID in the Netherlands. Cancer was reported as the cause of death approximately 1.5 times more often among people with ID than others. Because large differences were found that were related to screening cancers and cancers for which the primary tumor was unknown, this study's results raise concerns about equality in screening practices and cancer care for people with ID.

Cardiovascular risk screening of patients with serious mental illness or use of antipsychotics in family practice.

BACKGROUND: Patients with serious mental illness (SMI) and patients on antipsychotics (AP) have an elevated risk for cardiovascular diseases. In the Netherlands, the mental healthcare for these patients is increasingly taken care of by family practitioners (FP) as a result of a shift from secondary to primary care. Therefore, it is essential to increase our knowledge regarding the characteristics of this patient group and the (somatic) care provided by their FPs. The aim was to examine the rate of cardiovascular risk screening in patients with SMI or the use of AP in family practice. METHODS: We performed a retrospective cohort study of 151.238 patients listed in 24 family practices in the Netherlands. From electronic medical records we extracted data concerning diagnoses, measurement values of CVR factors, medication and frequency of visits over a 2 year period. Primary outcome was the rate of patients who were screened for CVR factors. We compared three groups: patients with SMI/AP without diabetes or CVD (SMI/AP-only), patients with SMI/AP and diabetes mellitus (SMI/AP + DM), patients with SMI/AP and a history of cardiovascular disease (SMI/AP + CVD). We explored factors associated with adequate screening using multilevel logistic regression. RESULTS: We identified 1705 patients with SMI/AP, 834 with a SMI diagnosis, 1150 using AP. The screening rate for CVR in the SMI/AP-only group (n = 1383) was adequate in 8.5%. Screening was higher in the SMI/AP - +DM (n = 206, 68.4% adequate, OR 24.6 (95%CI, 17.3-35.1) and SMI/AP + CVD (n = 116, 26.7% adequate, OR 4.2 (95%CI, 2.7-6.6). A high frequency of visits, age, the use of AP and a diagnosis of COPD were associated with a higher screening rate. In addition we also examined differences between patients with SMI and patients using AP without SMI. CONCLUSION: CVR screening in patients with SMI/AP is performed poorly in Dutch family practices. Acceptable screening rates were found only among SMI/AP patients with diabetes mellitus as comorbidity. The finding of a large group of AP users without a SMI diagnosis may indicate that FPs often prescribe AP off-label, lack information about the diagnosis, or use the wrong code.

Heart failure in primary care: prevalence related to age and comorbidity.

BACKGROUND: Diagnosing heart failure (HF) in primary care can be challenging, especially in elderly patients with comorbidities. Insight in the prevalence, age, comorbidity and routine practice of diagnosing HF in general practice may improve the process of diagnosing HF. AIM: To examine the prevalence of HF in relation to ageing and comorbidities, and routine practice of diagnosing HF in general practice. METHODS: A retrospective cohort study was performed using data from electronic health records of 56 320 adult patients of 11 general practices. HF patients were compared with patients without HF using descriptive analyses and χ2 tests. The following comorbidities were considered: chronic obstructive pulmonary disorder (COPD), diabetes mellitus (DM), hypertension, anaemia and renal function disorder (RFD). Separate analyses were performed for men and women. FINDINGS: The point prevalence of HF was 1.2% (95% confidence interval 1.13-1.33) and increased with each age category from 0.04% (18-44 years) to 20.9% (⩾85 years). All studied comorbidities were significantly (P<0.001) more common in HF patients than in patients without HF: COPD (24.1% versus 3.1%), DM (34.7% versus 6.5%), hypertension (52.7% versus 16.0%), anaemia (10.9% versus 2.3%) and RFD (61.8% versus 7.5%). N-terminal pro-BNP (NT-proBNP) was recorded in 38.1% of HF patients. CONCLUSIONS: HF is highly associated with ageing and comorbidities. Diagnostic use of NT-proBNP in routine primary care seems underutilized. Instruction of GPs to determine NT-proBNP in patients suspected of HF is recommended, especially In elderly patients with comorbidities.

Implementation of web-based hospital specialist consultations to improve quality and expediency of general practitioners' care: a feasibility study.

BACKGROUND: Rising healthcare costs due to unnecessary referrals to secondary healthcare services underscore the need for optimizing current referral procedures. This study investigates whether the use of web-based consultation (WBC) in general practice is a feasible alternative to decrease referrals. METHODS: Patients with lumbosacral radicular syndrome, knee complaints, or thyroid dysfunction, who visited the general practitioner (GP) between May 2015 and December 2016 were included for a WBC. We determined whether the GP would refer a patient to an outpatient clinic in the absence of a WBC and then compared this decision with the referral advice from a specialist. We further assessed the user-friendliness of the WBC service based on average recorded user time and feedback from the GPs. RESULTS: Seventy eligible WBCs submitted by GPs were analyzed. Our data showed a 46% absolute reduction in in-persons referrals in our study population. These findings confirmed the feasibility of using WBC. The median time spent to submit a WBC was five and 10 min for GPs and specialists respectively. On average, the WBC service saved €286 per WBC. The results of a questionnaire showed that GPs found WBC to be a user-friendly option which could help reduce the number of in-person referrals. CONCLUSION: We demonstrated that WBC is not only feasible but has the potential to reduce nearly half of all in-person referrals to outpatient clinics. WBC decreased healthcare expenses and proved to be a user-friendly and safe alternative to the standard referral process. WBC may potentially have a profound impact on healthcare expenditure if applied in a wider medical setting. For follow-up research, we recommend including a control group for comparative analyses.

Is the plasma aldosterone-to-renin ratio associated with blood pressure response to treatment in general practice?

BACKGROUND: Individualized antihypertensive treatment based on specific biomarkers such as renin may lead to more effective blood pressure control in patients with newly diagnosed essential hypertension. Recent studies suggested that the plasma aldosterone-to-renin ratio (ARR) may also be a candidate predictor for this purpose. OBJECTIVE: To assess whether the ARR is associated with the blood pressure response to antihypertensive treatment in patients with newly diagnosed hypertension. METHODS: In this prospective cohort study in primary care, we determined the ARR in patients with newly diagnosed hypertension prior to starting treatment. Treatment was categorized in five groups: no medication, use of angiotensin-converting-enzyme inhibitor or angiotensin receptor blocker, use of calcium channel blocker, use of diuretic, or use of beta blocker. We examined the relation between the ARR and blood pressure response within 1 year of treatment, taking into account the type of antihypertensive treatment and adjusting for gender, age, baseline blood pressure, and comorbidity. RESULTS: Out of 304 patients, we used 947 measurements (727 no medication, 220 medication) for analysis. There was no association between the ARR and the response in blood pressure, and this applied to each treatment group. Target blood pressure, defined as systolic blood pressure <140 mmHg, was reached in 31% of patients. There was no association between the ARR and reaching target blood pressure (OR 1.002, 95% CI 0.983-1.022). CONCLUSION: The ARR is not associated with the response in blood pressure within 1 year of antihypertensive treatment in primary care.

Gout and rheumatoid arthritis, both to keep in mind in cardiovascular risk management: A primary care retrospective cohort study.

OBJECTIVES: To assess in one time window cardiovascular risks for both patients with gout and patients with rheumatoid arthritis in a Dutch primary care population. METHODS: Retrospective matched cohort study with data from the electronic health records of 51 Dutch general practices. Participants were patients aged 30 years or older with an incident diagnosis of gout (n=2655) or rheumatoid arthritis (n=513), and matched non-disease controls (n=7891 and n=1850 respectively). At disease incidence date, patients and controls were compared for prevalence of hypertension, diabetes mellitus, hypercholesterolemia, and prior cardiovascular diseases. Patients without prior cardiovascular disease were followed for a first cardiovascular disease, and compared to controls using Kaplan-Meier survival curves and Cox proportional hazard analyses. RESULTS: Compared to controls, gout patients suffered more from hypertension (44.8%), diabetes (20.1%), hypercholesterolemia (13.7%), and prior cardiovascular disease (30%) (P<0.01), whereas rheumatoid arthritis patients (hypertension 28.5%; diabetes 11.7%; hypercholesterolemia 7.4%; prior cardiovascular disease 11.3%) did not (P>0.05). After adjustment, both gout and rheumatoid arthritis patients without prior cardiovascular disease were more likely to get a cardiovascular disease: hazard ratio (95% confidence interval) 1.44 (1.18 to 1.76), and 2.06 (1.34 to 3.16) respectively. CONCLUSIONS: This primary care study indicates that gout and rheumatoid arthritis are both independent risk factors for cardiovascular diseases, rheumatoid arthritis to some greater extent, whereas gout patients at first diagnosis had already an increased cardiovascular risk profile. It gives strong arguments for implementation of both rheumatic diseases in primary care guidelines on cardiovascular risk management.

How does additional diagnostic testing influence the initial diagnosis in patients with cognitive complaints in a memory clinic setting?

BACKGROUND: patients suspected of dementia frequently undergo additional diagnostic testing (e.g. brain imaging or neuropsychological assessment) after standard clinical assessment at a memory clinic. This study investigates the use of additional testing in an academic outpatient memory clinic and how it influences the initial diagnosis. METHODS: the initial diagnosis after standard clinical assessment (history, laboratory tests, cognitive screening and physical and neurological examination) and the final diagnosis after additional testing of 752 memory clinic patients were collected. We specifically registered if, and what type of, additional testing was requested. RESULTS: additional testing was performed in 518 patients (69%), 67% of whom underwent magnetic resonance imaging, 45% had neuropsychological assessment, 14% had cerebrospinal fluid analysis and 49% had (combinations of) other tests. This led to a modification of the initial diagnosis in 17% of the patients. The frequency of change was highest in patients with an initial non-Alzheimer's disease (AD) dementia diagnosis (54%, compared with 11 and 14% in patients with AD and 'no dementia'; P < 0.01). Finally, after additional testing 44% was diagnosed with AD, 9% with non-AD dementia and 47% with 'no dementia'. CONCLUSION: additional testing should especially be considered in non-AD patients. In the large group of patients with an initial AD or 'no dementia' diagnosis, additional tests have little diagnostic impact and may perhaps be used with more restraint.

The development of the Older Persons and Informal Caregivers Survey Minimum DataSet (TOPICS-MDS): a large-scale data sharing initiative.

INTRODUCTION: In 2008, the Ministry of Health, Welfare and Sport commissioned the National Care for the Elderly Programme. While numerous research projects in older persons' health care were to be conducted under this national agenda, the Programme further advocated the development of The Older Persons and Informal Caregivers Survey Minimum DataSet (TOPICS-MDS) which would be integrated into all funded research protocols. In this context, we describe TOPICS data sharing initiative (www.topics-mds.eu). MATERIALS AND METHODS: A working group drafted TOPICS-MDS prototype, which was subsequently approved by a multidisciplinary panel. Using instruments validated for older populations, information was collected on demographics, morbidity, quality of life, functional limitations, mental health, social functioning and health service utilisation. For informal caregivers, information was collected on demographics, hours of informal care and quality of life (including subjective care-related burden). RESULTS: Between 2010 and 2013, a total of 41 research projects contributed data to TOPICS-MDS, resulting in preliminary data available for 32,310 older persons and 3,940 informal caregivers. The majority of studies sampled were from primary care settings and inclusion criteria differed across studies. DISCUSSION: TOPICS-MDS is a public data repository which contains essential data to better understand health challenges experienced by older persons and informal caregivers. Such findings are relevant for countries where increasing health-related expenditure has necessitated the evaluation of contemporary health care delivery. Although open sharing of data can be difficult to achieve in practice, proactively addressing issues of data protection, conflicting data analysis requests and funding limitations during TOPICS-MDS developmental phase has fostered a data sharing culture. To date, TOPICS-MDS has been successfully incorporated into 41 research projects, thus supporting the feasibility of constructing a large (>30,000 observations), standardised dataset pooled from various study protocols with different sampling frameworks. This unique implementation strategy improves efficiency and facilitates individual-level data meta-analysis.

Geriatric hypotensive syndromes are not explained by cardiovascular autonomic dysfunction alone.

BACKGROUND: Though highly prevalent, the pathophysiology of orthostatic hypotension (OH), postprandial hypotension (PPH), and carotid sinus hypersensitivity (CSH) are rarely studied together. Therefore, we conducted such a comprehensive study focusing on the common role of the cardiovascular autonomic system. We hypothesized that in geriatric patients, OH, PPH, and CSH are manifestations of cardiovascular autonomic dysfunction and investigated state-of-the-art cardiovascular autonomic function indices in a group of geriatric falls or syncope patients. METHODS: In a cross-sectional study of 203 consecutive eligible falls clinic patients, we compared heart rate variability (HRV), blood pressure variability (BPV), and baroreflex sensitivity (BRS) as potential autonomic function determinants of the three different hypotensive syndromes. RESULTS: OH, PPH, and CSH were diagnosed in 53%, 57%, and 50% of the patients, respectively. In a population relevant for geriatric practice, we found no differences in HRV, BPV, and BRS between patients with and without OH, with and without PPH, and with and without CSH, respectively, nor between patients with and without falls, dizziness, or syncope as presenting symptom, respectively. CONCLUSIONS: In geriatric patients with hypotensive syndromes, cardiovascular autonomic function as measured by HRV, BPV, and BRS is comparable to patients without such syndromes. These findings argue against a single or dominant etiological factor, that is, cardiac autonomic dysfunction and underline the structured, broad, and multifactorial approach to elderly patients with falls and/or syncope as proposed in the current evidence-based syncope guidelines.

Diastolic blood pressure drop after standing as a clinical sign for increased mortality in older falls clinic patients.

BACKGROUND: Orthostatic hypotension, postprandial hypotension, and carotid sinus hypersensitivity are hypotensive syndromes with high prevalence in older people. However, their pathophysiology and prognostic significance remain largely unknown. METHODS: In a retrospective cohort study of 313 consecutive patients visiting our falls outpatient clinic, we examined the clustering of orthostatic hypotension, postprandial hypotension, and carotid sinus hypersensitivity in the same patients, which might reflect a shared similar pathophysiology. The value of hypotensive syndrome presence and the degree of blood pressure decline as prognostic indicators for mortality were assessed using Cox proportional hazards analyses. RESULTS: In 313 patients (mean age 78.7 ±â€Š8.0 years), 168 of 309 (54%), 175 of 302 (58%), and 143 of 272 (53%) were diagnosed with orthostatic hypotension, postprandial hypotension, and sinus carotid hypersensitivity, respectively. There was no clustering of the hypotensive syndromes. During a median follow-up of 23.0 months, 58 (19%) patients died. Orthostatic hypotension, but not postprandial hypotension or carotid sinus hypersensitivity, predicted mortality [hazard ratio 1.97; 95% confidence interval (CI) 1.11-3.47]. After adjusting for age, comorbidity and other baseline characteristics, this relationship was no longer significant. However, orthostatic hypotension with severe diastolic blood pressure decline of at least 20 mmHg remained a powerful independent predictor of mortality (hazard ratio 2.50; 95% CI 1.20-5.22). CONCLUSIONS: In falls clinic patients, hypotensive syndromes did not cluster and did not independently predict mortality. However, orthostatic hypotension with severe diastolic blood pressure decline was a powerful independent predictor of mortality and might be used prognostically as an easily available cardiovascular sign of increased mortality risk.

Unhealthy lifestyles during the life course: association with physical decline in late life.

BACKGROUND AND AIMS: This study aimed at examining the association between unhealthy lifestyle in young age, midlife and/or old age and physical decline in old age, and between chronic exposure to an unhealthy lifestyle throughout life and physical decline in old age. METHODS: The study sample included 1297 respondents of the Longitudinal Aging Study Amsterdam (LASA). Lifestyle in old age (55-85 y) was assessed at baseline, whereas lifestyle in young age (around 25 y) and midlife (around 40 y) were assessed retrospectively. Lifestyle factors included physical activity, body mass index (BMI), number of alcohol drinks per week and smoking. Physical decline was calculated as a change in physical performance score between baseline and six-year followup. RESULTS: Of the lifestyle factors present in old age, a BMI of 25-29 vs BMI < 25 kg/m2 (OR=1.6; 95% CI: 1.1-2.2) and a BMI of > or = 30 vs BMI < 25 kg/m2 (OR=1.8; 95% CI: 1.2-2.7) were associated with physical decline in old age. Being physically inactive in old age was not significantly associated with an increased risk of physical decline, although, being physically inactive in both midlife and old age increased the odds of physical decline in old age to 1.6 (95% CI: 1.1-2.4), compared with respondents who were physically inactive in midlife and physically active in old age. Being overweight in both age periods was associated with an OR of 1.5 (95% CI: 1.1-2.2). CONCLUSIONS: These data suggest that overweight in old age, and chronic exposure to physical inactivity or overweight throughout life, increases the risk of physical decline in old age. Therefore, physical activity and prevention of excessive weight at all ages should be stimulated, to prevent physical decline in old age.

Depression in older age is a risk factor for first ischemic cardiac events.

OBJECTIVE: Depressive disorders have been shown to be associated with cardiac diseases and death, but the underlying disease mechanism is unclear. The authors hypothesized that the cardiac morbidity and mortality after depression in late life is mediated by subclinical atherosclerosis and is thus confined to ischemic heart diseases. METHOD: Using the population-based cohort of the Longitudinal Aging Study Amsterdam, 2,403 men and women aged 55 and over without cardiac disease were followed to assess the onset of cardiac disease or cardiac death. Ischemic heart diseases (angina pectoris, [non]fatal myocardial infarction) were distinguished from other cardiac diseases (congestive heart failure, arrhythmia). Major depressive disorder (MDD) was defined according to Diagnostic and Statistical Manual of Mental Disorders, Third Edition (DSM-III) criteria. Subthreshold depression was defined as clinically relevant depressive symptoms not fulfilling DSM criteria. RESULTS: After a mean follow up of 7.2 years, 444 first cardiac events occurred, of which 252 were primary ischemic events and 192 other cardiac events. Cox regression analysis adjusted for physical health variables showed that, when compared with nondepressed respondents, those with MDD had a relative risk (RR) of 2.09 (95% confidence interval: 1.13-3.85) for any cardiac event. Considering only ischemic events, the RR conferred by MDD increased to 3.00 (1.51-5.93), whereas the RR declined to 0.96 (0.24-3.89) for all other cardiac events. Subthreshold depression did not increase the risk of future cardiac events. CONCLUSION: Major depression in older age predicts first cardiac events. The excess cardiac morbidity and cardiac mortality after major depression could entirely be attributed to ischemic heart diseases.

Change in serum albumin and subsequent decline in functional status in older persons.

BACKGROUND AND AIMS: This study examines whether a three-year change in serum albumin concentration is associated with subsequent decline in functional status in older persons. METHODS: A total of 588 participants from the Longitudinal Aging Study Amsterdam aged 65-85 years were followed for six years. The three-year change in serum albumin was classified in four groups: chronic low (< or =43 g/L at both time points), decrease (decrease of 2.4% or more) from normal to low, decrease but still normal, and stable normal albumin (reference group). During the subsequent three years, absolute change and a decline of one standard deviation or more (termed substantial decline) in functional status was assessed. Functional status was measured in two ways: using performance tests and self-reported functional ability. RESULTS: Substantial decline in functional performance and functional ability was observed in 243 persons (41.3%) and 133 persons (22.6%), respectively. After adjustment for baseline functional status and potential confounders, chronic low albumin and a decrease from normal to low albumin were associated with a greater absolute decline in functional performance and in self-reported functional ability. Using the outcome substantial decline in functional status, only decrease to low serum albumin was associated with decline in functional ability [odds ratio (OR)=1.97; one-sided 95% Confidence Limit (CL)=1.09]. CONCLUSIONS: This study indicates that chronic low serum albumin is a determinant of decline in functional status. However, a decrease in serum albumin from normal to low levels but within the normal range was a stronger determinant of future decline in functional status. Change in serum albumin level within the normal range measured between two points in time may be used as a general marker of future functional decline.

Serum albumin and muscle strength: a longitudinal study in older men and women.

OBJECTIVES: To examine whether low serum albumin is associated with low muscle strength and future decline in muscle strength in community-dwelling older men and women. DESIGN: Population-based cohort study. SETTING: The Longitudinal Aging Study Amsterdam. PARTICIPANTS: Six hundred seventy-six women and 644 men aged 65 to 88. MEASUREMENTS: Serum albumin was determined at baseline. Muscle strength was assessed using grip strength at baseline, after 3 (n=1,009), and 6 (n=741) years. The outcomes were continuous baseline muscle strength, 3- and 6-year change in muscle strength, and a dichotomous indicator for substantial decline (a decrease if > or =1 standard deviations for women=11 kg, for men=12 kg) in muscle strength. RESULTS: Mean serum albumin concentration+/-standard deviation was 45.0+/-3.3 g/L for women and 45.2+/-3.2 g/L for men. At baseline, adjusting for age, lifestyle factors, and chronic conditions, lower serum albumin was cross-sectionally associated with weaker muscle strength (P<.001) in women and men. After 3 years of follow-up, mean decline in muscle strength was -5.6+/-10.9 kg in women and -9.6+/-11.9 kg in men. After adjustment for potential confounders, lower serum albumin was associated with muscle strength decline over 3 years (P<.01) in women and men (beta=0.57, standard error (SE)=0.18; beta=0.37, SE=0.16, respectively). Lower serum albumin was also associated with substantial decline in muscle strength in women (per unit albumin (g/L) adjusted odds ratio (OR)=1.14, one-sided 95% confidence limit (CL)=1.07) and men (per unit albumin (g/L) adjusted OR=1.14, 95% CL=1.08). Similar but slightly weaker associations were found between serum albumin and 6-year change in muscle strength (P<.05). CONCLUSION: These results suggest that low serum albumin, even within the normal range, is independently associated with weaker muscle strength and future decline in muscle strength in older women and men.

Lower levels of serum albumin and total cholesterol and future decline in functional performance in older persons: the Longitudinal Aging Study Amsterdam.

BACKGROUND: Both serum albumin and total cholesterol are potential markers of frailty. A decline in functional status is one of the key components of frailty. OBJECTIVE: The aim of this study was to investigate the association of serum albumin and total cholesterol, separately and combined, with future decline in functional performance. DESIGN: The Longitudinal Aging Study Amsterdam, an ongoing population-based longitudinal study, started in 1992/1993 with a follow-up every 3 years. PARTICIPANTS: 1,064 men and women aged 55-85 years with complete data on serum albumin and total cholesterol at baseline, and functional performance at baseline and 3-year follow-up. MEASUREMENTS: At baseline, serum albumin and total cholesterol were measured. At baseline and 3 years later, decline in functional status was measured with three performance tests (chair stand, 3-metre walk, putting on and taking off a cardigan). Associations were adjusted for age, life-style and health-related factors. RESULTS: Albumin concentration was not associated with decline in functional performance in men and women. Women with lower serum total cholesterol concentration (
