RESUMO
Understanding individual variability in response to physical activity is key to developing more effective and personalised interventions for healthy ageing. Here, we aimed to unpack individual differences by using longitudinal data from a randomised-controlled trial of a 12-month muscle strengthening intervention in older adults. Physical function of the lower extremities was collected from 247 participants (66.3 ± 2.5 years) at four time-points. At baseline and at year 4, participants underwent 3 T MRI brain scans. K-means longitudinal clustering was used to identify patterns of change in chair stand performance over 4 years, and voxel-based morphometry was applied to map structural grey matter volume at baseline and year 4. Results identified three groups showing trajectories of poor (33.6%), mid (40.1%), and high (26.3%) performance. Baseline physical function, sex, and depressive symptoms significantly differed between trajectory groups. High performers showed greater grey matter volume in the motor cerebellum compared to the poor performers. After accounting for baseline chair stand performance, participants were re-assigned to one of four trajectory-based groups: moderate improvers (38.9%), maintainers (38.5%), improvers (13%), and decliners (9.7%). Clusters of significant grey matter differences were observed between improvers and decliners in the right supplementary motor area. Trajectory-based group assignments were unrelated to the intervention arms of the study. In conclusion, patterns of change in chair stand performance were associated with greater grey matter volumes in cerebellar and cortical motor regions. Our findings emphasise that how you start matters, as baseline chair stand performance was associated with cerebellar volume 4 years later.

BACKGROUND: The ability to accurately predict survival in older adults is crucial as it guides clinical decision making. The added value of using various health indicators as well as changes in these indicators for predicting mortality remains unclear. The aim of this study was to investigate whether changes in health indicators such as frailty and physical performance improve mortality predictions in old age. METHODS: This is a population based prospective cohort study on 995 community-dwelling people aged 68-92 years from the Longitudinal Aging Study Amsterdam. Two measurements at a three-year interval (1995/1996 and 1998/1999) were available for the frailty index, frailty phenotype, grip strength, walking speed, and Mini-Mental State Examination (MMSE). Cox regression was used to analyze mortality risks associated with the current health status and changes in health, with mortality data up to 2017. The extent to which these health indicators improved mortality predictions compared to models with age and sex only was assessed by the area under the receiver operating characteristic curve (AUC). RESULTS: The AUC of age and sex for five-year mortality was 72.8% (95% CI 69.0 - 76.5) and was the lowest in the oldest old (age > 80.5 years). The added AUC of the current status of health indicators ranged from 0.7 to 3.3%. The added AUC of the three-year change was lower, ranging from -0.0 to 1.1%, whereas the added AUC of three-year change and current status combined was similar to current status alone, ranging from 0.6 to 3.2%. Across age, the added AUC of current status was highest in the oldest old, however there was no such pattern using three-year change. Overall, the frailty index appeared to improve mortality predictions the most, followed by the frailty phenotype, MMSE, grip strength, and walking speed. CONCLUSIONS: Current health status improved mortality predictions better than changes in health. Its contribution was highest in the oldest old, but the added value to models with age and sex only was limited.

OBJECTIVES: The aims of this study were to describe changes in height during childhood and to investigate potential changes in the proportion of children attaining final height in childhood and in correlations between child and adult height across birth cohorts. METHODS: We included 363 059 children (179 906 girls) from the Copenhagen School Health Records Register, who were born between 1930 and 1989, with height measurements at ages 7, 10, or 13 years. Linkages to data resources containing adult height values between ages 18 and 69 years were possible for a subpopulation of 96 133 individuals (23 051 women). Birth years were categorized as 1930 to 1939, 1940 to 1949, and 1950 to 1989. Descriptive height statistics were estimated by birth years and birth cohorts. Height correlations were examined using sex- and age-specific partial Pearson correlation analyses and meta-regression techniques. RESULTS: Across 60 birth years, mean child heights at age 7 increased by 2.9 cm in girls and 3.0 cm in boys, and adult heights increased as well. The proportions of children attaining final height by age 13 remained low across the birth cohorts; nonetheless, there was a significant increase from 0.7% to 1.5% in girls only (P < .0001). Both child-child and child-adult height correlations were strong and remained relatively stable across birth cohorts. CONCLUSIONS: Mean child and adult height increased during the study period, but the proportion of children attaining final height at age 13 remained low. Child-child and child-adult height correlations were largely unchanged across birth cohorts.

Disrupted sleep is a contributing factor to cognitive ageing, while also being associated with neurodegenerative disorders. Little is known, however, about the relation of sleep and the gradual cognitive changes over the adult life course. Sleep electroencephalogram (EEG) patterns are potential markers of the cognitive progress. To test this hypothesis, we assessed sleep architecture and EEG of 167 men born in the Copenhagen Metropolitan Area in 1953, who, based on individual cognitive testing from early (~18 years) to late adulthood (~58 years), were divided into 85 subjects with negative and 82 with positive cognitive change over their adult life. Participants underwent standard polysomnography, including manual sleep scoring at age ~58 years. Features of sleep macrostructure were combined with a number of EEG features to distinguish between the two groups. EEG rhythmicity was assessed by spectral power analysis in frontal, central and occipital sites. Functional connectivity was measured by inter-hemispheric EEG coherence. Group differences were assessed by analysis of covariance (p < 0.05), including education and severity of depression as potential covariates. Subjects with cognitive decline exhibited lower sleep efficiency, reduced inter-hemispheric connectivity during rapid eye movement (REM) sleep, and slower EEG rhythms during stage 2 non-REM sleep. Individually, none of these tendencies remained significant after multiple test correction; however, by combining them in a machine learning approach, the groups were separated with 72% accuracy (75% sensitivity, 67% specificity). Ongoing medical screenings are required to confirm the potential of sleep efficiency and sleep EEG patterns as signs of individual cognitive progress.

AIMS: Alcohol consumption is a modifiable and plausible risk factor for age-related cognitive decline but more longitudinal studies investigating the association are needed. Our aims were to estimate associations of adult-life alcohol consumption and consumption patterns with age-related cognitive decline. METHODS: We investigated the associations of self-reported adult-life weekly alcohol consumption and weekly extreme binge drinking (≥10 units on the same occasion) with changes in test scores on an identical validated test of intelligence completed in early adulthood and late midlife in 2498 Danish men from the Lifestyle and Cognition Follow-up study 2015. Analyses were adjusted for year of birth, retest interval, baseline IQ, education and smoking. RESULTS: Men with adult-life alcohol consumption of more than 28 units/week had a larger decline in IQ scores from early adulthood to late midlife than men consuming 1-14 units/week (B29-35units/week = -3.6; P < 0.001). Likewise, a 1-year increase in weekly extreme binge drinking was associated with a 0.12-point decline in IQ scores (P < 0.001). Weekly extreme binge drinking explained more variance in IQ changes than average weekly consumption. In analyses including mutual adjustment of weekly extreme binge drinking and average weekly alcohol consumption, the estimated IQ decline associated with extreme binge drinking was largely unaffected, whereas the association with weekly alcohol consumption became non-significant. CONCLUSIONS: Adult-life heavy alcohol consumption and extreme binge drinking appear to be associated with larger cognitive decline in men. Moreover, extreme binge drinking may be more important than weekly alcohol consumption in relation to cognitive decline.

Observed associations between breastfeeding and reduced risk of type 2 diabetes in adulthood may be confounded. We examined if the duration of breastfeeding in infancy was associated with the risk of type 2 diabetes in adulthood after adjustment for a range of prenatal and postnatal risk factors. We prospectively followed 6,044 individuals from the Copenhagen Perinatal Cohort born 1959-1961. Duration of any breastfeeding (≤0.5, >0.5-1, >1-2, >2-4, >4 months) was assessed at the infant's 1-year health examination. We estimated hazard ratios (HRs) with 95% confidence intervals (CIs) for type 2 diabetes (at age ≥30 years, 237 persons) by breastfeeding duration without and with adjustment for parental social status and education, maternal pre-pregnancy body mass index (BMI), maternal diabetes and smoking during pregnancy, gestational weight gain, parity, preterm birth, birth weight, sex, and BMI at ages 7 and 41-43 years. In the unadjusted analysis, compared with infants breastfed for ≤0.5 month, those breastfed for >4 months had a 51% reduced risk of type 2 diabetes (HR = 0.49; 95% CI [0.32, 0.75]). After the stepwise adjustment for putative early life confounders, this was attenuated to a nonsignificant 31% reduced risk (HR = 0.69; 95% CI [0.44, 1.07]). Adjustment for childhood and adulthood BMI minimally changed the results. We found that the inverse association between the duration of breastfeeding and risk of type 2 diabetes in adulthood is considerably weakened and no longer significant after adjustment for prenatal and postnatal factors in the infant and mother.

Earlier studies report inconsistent associations between education and cognitive aging. We assessed the association, accounting for selective dropout due to death or dementia, and, in a subsample, accounting for confounding by early-life intelligence. Data from the Danish component of the Survey of Health, Ageing and Retirement in Europe (n = 3,400) were linked to registry data (education records, dementia diagnoses, and mortality) and the Danish Conscription Database (youth intelligence measurements for 854 men). Word recall and verbal fluency were assessed up to 4 times over 10 years (2004-2013) and combined by averaging the z scores. We fitted a joint model linking a time-to-event model for dementia or death to a linear mixed-effects model for cognitive change. Rate of cognitive decline was slower among people with high education compared with low education (ß = 0.112, 95% confidence interval (CI): 0.056, 0.170). Adjusting for youth intelligence did not attenuate the association between education and cognitive decline (crude ß = 0.136, 95% CI: 0.028, 0.244 vs. adjusted ß = 0.145, 95% CI: 0.022, 0.269). The results suggest that higher education may slow cognitive decline in later life. In this sample, results changed little when accounting for selective attrition and confounding by intelligence.

The study investigated whether age at attainment of 20 developmental milestones within the areas of language, walking, eating, dressing, social interaction, and toilet training was associated with adult intelligence. Mothers of 821 children of the Copenhagen Perinatal Cohort recorded 20 developmental milestones at a 3-year examination, and all children were administered the Wechsler Adult Intelligence Scale when they were 20-34 years old. Later attainment of a number of milestones was associated with lower adult IQ with the strongest associations found for those related to language and social interaction. The adjusted full-scale IQ means were 107.0, 101.8, and 100.6 for being able to form a sentence at less than 24 months, at 24 months, and later than 24 months.

BACKGROUND: The mechanisms underlying the association of parental socioeconomic position with later life allostatic load remain unclear. The present study aims to examine potential pathways underlying this association: personality, social relations, intelligence and education. METHODS: The study comprised 361 members of the Copenhagen Perinatal Cohort who participated in two subsequent follow-ups: the Prenatal Development Project (mean age 27 years) and the Copenhagen Aging and Midlife Biobank study (mean age 50 years). Allostatic load was based on 14 biomarkers representing the inflammatory, metabolic and cardiovascular system measured at midlife. Information on potential mediators was collected in young adulthood, and their role in the association of parental socioeconomic position with midlife allostatic load were examined in linear regression path analyses. RESULTS: Parental socioeconomic position at one year was inversely associated with midlife allostatic load (ß = - 0.238, p < .001). No mediation effects were found for personality or social relations. In a model including intelligence and education, a significant indirect effect was found for education (ß = - 0.151, p < .001). A significant direct effect remained (ß = - 0.111, p = .040). CONCLUSIONS: Parental socioeconomic position was inversely associated with allostatic load in midlife. Results suggest that part of this association was mediated by education. A better understanding of the non-cognitive pathways related to education is an important prerequisite for the development of effective intervention strategies.

OBJECTIVE: The study aimed to evaluate the impact of a 15-month intervention on dietary intake conducted among obesity-prone normal-weight pre-school children. DESIGN: Information on dietary intake was obtained using a 4 d diet record. A diet quality index was adapted to assess how well children's diet complied with the Danish national guidelines. Linear regression per protocol and intention-to-treat analyses of differences in intakes of energy, macronutrients, fruit, vegetables, fish, sugar-sweetened beverages and diet quality index between the two groups were conducted. SETTING: The Healthy Start study was conducted during 2009-2011, focusing on changing diet, physical activity, sleep and stress management to prevent excessive weight gain among Danish children. SUBJECTS: From a population of 635 Danish pre-school children, who had a high birth weight (≥4000 g), high maternal pre-pregnancy BMI (≥28·0 kg/m2) or low maternal educational level (<10 years of schooling), 285 children completed the intervention and had complete information on dietary intake. RESULTS: Children in the intervention group had a lower energy intake after the 15-month intervention (group means: 5·29 v. 5·59 MJ, P=0·02) compared with the control group. We observed lower intakes of carbohydrates and added sugar in the intervention group compared with the control group after the intervention (P=0·002, P=0·01). CONCLUSIONS: The intervention resulted in a lower energy intake, particularly from carbohydrates and added sugar after 15 months of intervention, suggesting that dietary intake can be changed in a healthier direction in children predisposed to obesity.

INTRODUCTION: We examined the association between cognitive ability in young adulthood and dementia in Danish men, brothers, and male twins. METHODS: In total, 666,986 men born between 1939 and 1959 were identified for dementia diagnosis in national registries from 1969 to 2016. The association between cognitive ability from draft board examination and dementia was examined using Cox regression. RESULTS: During a 44-year follow-up, 6416 (0.96%) men developed dementia, 1760 (0.26%) and 970 (0.15%) of which were classified as Alzheimer's and vascular dementia, respectively. Low cognitive ability was associated with increased risk of dementia (hazard ratio [HR]per SD decrease 1.33 [95% confidence interval {CI} = 1.30-1.35]) with the strongest associations for vascular dementia (HRper SD decrease 1.47 [95% CI = 1.31-1.56]) and a weaker for Alzheimer's disease (HRper SD decrease 1.07 [95% CI = 1.03-1.13]). The intrabrother and twin analyses (taking shared family factors into account) showed attenuated risk estimates but with wide CIs. DISCUSSION: Low early-life cognitive ability increases the risk of dementia before the age of 78 years. The association is partly explained by shared family factors.

We here describe a multimodality neuroimaging containing data from healthy volunteers and patients, acquired within the Lundbeck Foundation Center for Integrated Molecular Brain Imaging (Cimbi) in Copenhagen, Denmark. The data is of particular relevance for neurobiological research questions related to the serotonergic transmitter system with its normative data on the serotonergic subtype receptors 5-HT1A, 5-HT1B, 5-HT2A, and 5-HT4 and the 5-HT transporter (5-HTT), but can easily serve other purposes. The Cimbi database and Cimbi biobank were formally established in 2008 with the purpose to store the wealth of Cimbi-acquired data in a highly structured and standardized manner in accordance with the regulations issued by the Danish Data Protection Agency as well as to provide a quality-controlled resource for future hypothesis-generating and hypothesis-driven studies. The Cimbi database currently comprises a total of 1100 PET and 1000 structural and functional MRI scans and it holds a multitude of additional data, such as genetic and biochemical data, and scores from 17 self-reported questionnaires and from 11 neuropsychological paper/computer tests. The database associated Cimbi biobank currently contains blood and in some instances saliva samples from about 500 healthy volunteers and 300 patients with e.g., major depression, dementia, substance abuse, obesity, and impulsive aggression. Data continue to be added to the Cimbi database and biobank.

The aim of this study was to translate, culturally adapt and evaluate the psychometric properties of the Pain Self-Efficacy Questionnaire (PSEQ) in a population of patients with fibromyalgia in Denmark. The study sample included 102 patients diagnosed with fibromyalgia referred to a specialist clinic. The PSEQ was translated and adapted to a Danish setting using a standard stepwise forward-backward translation procedure, followed by initial testing and focus group interview. Reliability was examined by analysing internal consistency and test-retest agreement. Construct validity was examined by investigating dimensionality, targeting, local independence, category functioning and differential item functioning (DIF). Reliability was high: Cronbach's alpha 0.88, test-retest correlation 0.93, intraclass correlation coefficient (ICC) 0.89 and item-total correlations 0.44-0.70. Factor analyses and item response (IRT) models indicated unidimensionality, and the PSEQ-DK was well targeted to the sample. High interitem correlation was observed between two items, indicating local dependence, and item misfit and DIF were observed for a few items. However, the overall fit of the scale to a single-factor model and IRT models supported acceptable construct validity. The PSEQ-DK showed acceptable psychometric properties and can therefore represent a reliable and valid measure for evaluating self-efficacy in patients with fibromyalgia in Denmark.

Several neurological variables have been investigated as premorbid biomarkers of vulnerability for schizophrenia and other related disorders. The current study examined whether childhood dyspraxia predicted later adult nonaffective-psychosis-spectrum disorders. From a standardized neurological examination performed with children (aged 10-13) at genetic high risk of schizophrenia and controls, several measures of dyspraxia were used to create a scale composed of face/head dyspraxia, oral articulation, ideomotor dyspraxia (clumsiness), and dressing dyspraxia (n = 244). Multinomial logistic regression showed higher scores on the dyspraxia scale predict nonaffective-psychosis-spectrum disorders relative to other psychiatric disorders and no mental illness outcomes, even after controlling for genetic risk, χ2 (4, 244) = 18.61, p < .001. Findings that symptoms of dyspraxia in childhood (reflecting abnormalities spanning functionally distinct brain networks) specifically predict adult nonaffective-psychosis-spectrum disorders are consistent with a theory of abnormal connectivity, and they highlight a marked early-stage vulnerability in the pathophysiology of nonaffective-psychosis-spectrum disorders.

BACKGROUND: Over the past 30 years, clinical trials have resulted in several successful pharmacotherapies for obsessive-compulsive disorder (OCD), yet patients in clinical settings often report inadequate response. This study compares clinical characteristics of treatment-seeking OCD patients to the inclusion/exclusion criteria used in pharmacotherapy trials. METHODS: The sample consisted of 325 community members with a DSM-IV diagnosis of OCD who underwent systematic interviews with clinicians knowledgeable in the diagnosis and treatment of OCD. We compiled pharmacotherapy studies for OCD published between 1980 and 2010 using Medline, PubMed, and library resources, and estimated the proportion of patients in each decade satisfying the most common inclusion/exclusion criteria. RESULTS: We included 39 clinical trials and found 72% of the 325 patients would have been excluded from trials conducted between 1980 and 2010. Exclusion was projected as dramatically lower for trials conducted between 1980 and 1989 (19.7%) compared with 74.8% for trials conducted between 1990 and 1999 and 76.9% for trials between 2000 and 2010. CONCLUSIONS: The majority of treatment-seeking individuals with OCD would not qualify for OCD treatment studies due to comorbid psychiatric disorders, and failure to meet OCD severity threshold criteria. This illustrates the need to include a more community-representative sample of OCD patients in clinical trials examining pharmacotherapy efficacy.

AIMS AND OBJECTIVES: To investigate how virtual admission during acute exacerbation influences self-efficacy in patients with chronic obstructive pulmonary disease, compared with conventional hospital admission. BACKGROUND: Telemedicine solutions have been highlighted as a possible way to increase self-efficacy in patients with chronic diseases, such as chronic obstructive pulmonary disease. However, little is known about how telemedicine-based virtual admission as a replacement of hospital admission during acute exacerbation affects chronic obstructive pulmonary disease patients' self-efficacy. DESIGN: This study was a nonblinded, randomised clinical multicentre trial. The study was a substudy to The Virtual Hospital, investigating the feasibility and safety of telemedicine-based treatment at home for patients with acute exacerbation of chronic obstructive pulmonary disease. METHODS: Participants were consecutively randomised to virtual admission or conventional hospital admission. Data from 50 patients were analysed. Self-efficacy was assessed at baseline, three days after discharge, and also six weeks and three months after discharge, using the Danish version of 'The chronic obstructive pulmonary disease self-efficacy scale'. RESULTS: Intergroup comparison showed no significant differences between the two groups at baseline, three days after discharge, six weeks after discharge or three months after discharge. Furthermore, intragroup comparison did not reveal significant differences in the chronic obstructive pulmonary disease self-efficacy scale mean sum score within the two groups. CONCLUSIONS: The results of the study suggest that there is no difference between self-efficacy in chronic obstructive pulmonary disease patients undergoing virtual admission, compared with conventional hospital admission. However, the anticipated sample size could not be reached, which prompts caution regarding interpretation of the findings. RELEVANCE TO CLINICAL PRACTICE: This study provides new insight into how virtual admission affects chronic obstructive pulmonary disease patients' self-efficacy. Clinicians should consider the timing, duration and the content in the design of telemedical interventions directed at improving chronic obstructive pulmonary disease patients' self-efficacy, as telemedicine solutions alone may not be sufficient to enhance self-efficacy.

A potential role of chemokines in the pathophysiology of Autism Spectrum Disorders (ASDs) has been previously suggested. In a recent study we examined levels of three inflammatory chemokines (MCP-1, MIP-1α and RANTES) in samples of amniotic fluid of children diagnosed later in life with ASD and controls frequency-matched to cases on gender and year of birth. In this follow-up study, levels of the same chemokines were analyzed postnatally in dried blood spot samples from the same subjects utilizing the Danish Newborn Screening Biobank. Crude estimates showed decreased levels of RANTES. In the adjusted estimates, no differences were found in levels of the three examined chemokines in ASD cases compared to controls. Our findings may cautiously suggest an altered cell-mediated immunity during the early neonatal period in ASD. Further research is needed to examine the relationship between maternal/fetal and neonatal chemokine levels and their role in ASD.

INTRODUCTION: Elevated levels of chemokines have been reported in plasma and brain tissue of individuals with Autism Spectrum Disorders (ASD). The aim of this study was to examine chemokine levels in amniotic fluid (AF) samples of individuals diagnosed with ASD and their controls. MATERIAL AND METHODS: A Danish Historic Birth Cohort (HBC) kept at Statens Serum Institute, Copenhagen was utilized. Using data from Danish nation-wide health registers, a case-control study design of 414 cases and 820 controls was adopted. Levels of MCP-1, MIP-1α and RANTES were analyzed using Luminex xMAP technology. Case-control differences were assessed as dichotomized at below the 10th percentile or above the 90th percentile cut-off points derived from the control biomarker distributions (logistic regression) or continuous measures (tobit regression). RESULTS AND CONCLUSION: AF volume for 331 cases and 698 controls was sufficient for Luminex analysis. Including all individuals in the cohort yielded no significant differences in chemokine levels in cases versus controls. Logistic regression analyses, performed on individuals diagnosed using ICD-10 only, showed increased risk for ASD with elevated MCP-1 (elevated 90th percentile adjusted OR: 2.32 [95% CI: 1.17-4.61]) compared to controls. An increased risk for infantile autism with elevated MCP-1 was also found (adjusted OR: 2.28 [95% CI: 1.16-4.48]). Elevated levels of MCP-1 may decipher an etiologic immunologic dysfunction or play rather an indirect role in the pathophysiology of ASD. Further studies to confirm its role and to identify the potential pathways through which MCP-1 may contribute to the development of ASD are necessary.

BACKGROUND: To examine the effects of low to moderate alcohol consumption during pregnancy on child motor function at age 5. METHODS: A prospective follow-up study of 685 women and their children sampled from the Danish National Birth Cohort based on maternal alcohol consumption during pregnancy. At 5 years of age, the children were tested with the "Movement Assessment Battery for Children" (MABC). Parental education, maternal IQ, prenatal maternal smoking, the child's age at testing, and gender of child were considered core confounders, while the full model also controlled for prenatal maternal binge drinking episodes, age, maternal prepregnancy body mass index, parity, home environment, postnatal parental smoking, health status, and indicators for hearing and vision impairment. RESULTS: There were no systematic or significant differences in motor function between children of mothers reporting low to moderate levels of average alcohol consumption during pregnancy and children of mothers who abstained. CONCLUSIONS: In this study, we found no systematic association between low to moderate maternal alcohol intake during pregnancy and child motor function at age 5.

PRIMARY OBJECTIVE: To investigate the emotional well-being of relatives of patients with a severe brain injury in the acute setting, as well as risk factors associated with high anxiety and depression scores and impaired quality-of-life. RESEARCH DESIGN: Clinical convenience sample. METHODS AND PROCEDURES: Participants included 45 relatives of patients with severe brain injury recruited at a NICU. All relatives completed selected scales from the SCL-90-R and SF-36 â¼ 14 days after injury. Data concerning the condition of the patient were also collected. MAIN OUTCOME AND RESULTS: Of the relatives, 51% and 69% reported anxiety and depression, respectively, as well as significantly impaired quality-of-life compared to normal reference populations. Regression analysis revealed that up to 20% of the variance in depression and anxiety scores could be explained by the CRASH 2 Mortality prediction. CONCLUSIONS: The majority of the relatives had severely impaired quality-of-life and symptoms of anxiety and depression during the patient's NICU stay. Future research is required to explore stressors and evaluate effects of psychological intervention in the acute setting.
