The Impact

IntroductionADHD occurs in 3–5% of children and adults. Yet little is known about ADHD in elderly.ObjectivesTo review the literature and to present first Dutch epidemiological data on ADHD in elderly (VUmc/LASA and PsyQ).AimsThe study aims to estimate the prevalence of ADHD in eldery and to correlate symptoms of ADHD with comorbidity patterns, cognitive decline and somatic disorders. This knowledge may help predict the future of the current group of adults with ADHD.MethodsThe Longitudinal Aging Study Amsterdam (LASA) included a selfreport questionnaire for ADHD in 2009 in around 1500 elderly, aged 63–94 years. From those with low, intermediate and high scores, a random sample was interviewed using the DIVA, a structured Diagnostic Interview for ADHD in adults (N = 234).ResultsFirst data on prevalence of ADHD in elderly in the general Dutch population will be discussed. The long term consequences of the persistence of the disorder in adults and elderly, and the impact for the organisation of treatment of this lifespan disorder will be reviewed.ConclusionsThe continuity of ADHD symptoms and impairment from childhood into to old age, may pose psychiatric services for important questions like the usefulness of separate treatment facilities for different age groups in case of a lifespan disorder like ADHD.

Abstract Purpose Delay of routine medical care during the COVID-19 pandemic may have serious consequences for the health and functioning of older adults. The aim of this study was to investigate whether older adults reported cancellation or avoidance of medical care during the first months of the COVID-19 pandemic, and to explore associations with health and socio-demographic characteristics. Methods Cross-sectional data of 880 older adults aged ≥ 62 years (mean age 73.4 years, 50.3% female) were used from the COVID-19 questionnaire of the Longitudinal Aging Study Amsterdam, a cohort study among community-dwelling older adults in the Netherlands. Cancellation and avoidance of care were assessed by self-report, and covered questions on cancellation of primary care (general practitioner), cancellation of hospital outpatient care, and postponed help-seeking. Respondent characteristics included age, sex, educational level, loneliness, depression, anxiety, frailty, multimorbidity and information on quarantine. Results 35% of the sample reported cancellations due to the COVID-19 situation, either initiated by the respondent (12%) or by healthcare professionals (29%). Postponed help-seeking was reported by 8% of the sample. Multimorbidity was associated with healthcare-initiated cancellations (primary care OR = 1.92, 95% CI = 1.09–3.50; hospital OR = 1.86, 95% CI = 1.28–2.74) and respondent-initiated hospital outpatient cancellations (OR = 2.02, 95% CI = 1.04–4.12). Depressive symptoms were associated with postponed help-seeking (OR = 1.15, 95% CI = 1.06–1.24). Conclusion About one third of the study sample reported cancellation or avoidance of medical care during the first months of the pandemic, and this was more common among those with multiple chronic conditions. How this impacts outcomes in the long term should be investigated in future research.

Abstract Background Baseline frailty index (FI) values have been shown to predict mortality among older adults, but little is known about the effects of changes in FI on mortality. Methods In a coordinated approach, we analyzed data from 4 population-based cohorts: the Health and Retirement Study (HRS), the Survey of Health, Ageing and Retirement in Europe (SHARE), the English Longitudinal Survey of Ageing (ELSA), and the Longitudinal Aging Study Amsterdam (LASA), comprising a total of 24 961 respondents (65+), 95 897 observations, up to 9 repeated FI assessments, and up to 23 years of mortality follow-up. The effect of time-varying FI on mortality was modeled with joint regression models for longitudinal and time-to-event data. Results Differences (of 0.01) in current FI levels (hazard ratio [HR] = 1.04, 95% credible interval [CI] = 1.03–1.05) and baseline FI levels (HR = 1.03, 95% CI = 1.03–1.05) were consistently associated with mortality across studies. Importantly, individuals with steeper FI growth also had a higher mortality risk: An increase in annual FI growth by 0.01 was associated with an increased mortality risk of HR = 1.56 (95% CI = 1.49–1.63) in HRS, HR = 1.24 (95% CI = 1.13–1.35) in SHARE, HR = 1.40 (95% CI = 1.25–1.52) in ELSA, and HR = 1.71 (95% CI = 1.46–2.01) in LASA. Conclusions FI changes predicted mortality independently of baseline FI differences. Repeated assessment of frailty and individual’s frailty trajectory could provide a means to anticipate further health deterioration and mortality and could thus support clinical decision making.

Research has indicated the need to consider the ageing process with technology adoption by older adults. This study examined psychological, health, social and demographic predictors with starting and stopping Internet use by older adults (2002–2012). Data were used from the Longitudinal Aging Study Amsterdam, and Cox regression analyses were done to test predictors over time with starting or stopping Internet use. The results indicated that older adults starting to use the Internet (11.6%) outnumbered those who stopped (3.1%). Psychological, health, social and demographic predictors separately predicted starting and stopping Internet use. Starting use was predicted by lower age, higher education, normal cognition and living alone. The predictors in stopping use were being younger, having a high sense of mastery and being higher educated. The results need to be interpreted as indicative due to the small number of stoppers. Suggestions are made on how to improve usability.

Samenvatting Door de recente verhoging van de AOW-leeftijd in Nederland is een nieuwe groep ontstaan: de betaald werkenden tussen de oude AOW-leeftijd van 65 jaar en de nieuwe AOW-leeftijd, de ‘65-pre-AOW’ers’. In een eerste kenschets van deze groep vergelijken wij hun werk- en individuele kenmerken met die van de 61-64-jarige werkers, de ‘61-64’ers’, en de werkers boven de nieuwe AOW-leeftijd, de ‘post-AOW’ers’. In 2019 verschaften 764 61-70-jarige deelnemers aan de voor Nederland representatieve Longitudinal Aging Study Amsterdam gegevens over sociaal-demografische kenmerken, financiële situatie, gezondheid, werkcapaciteit en werkkenmerken. Het aandeel werkenden verschilde duidelijk naar leeftijd: 67% bij de 61-64’ers, 48% bij de 65-pre-AOW’ers en 16% bij de post-AOW’ers. Ook het gemiddeld aantal werkuren per week verschilde en bedroeg 31, 27 respectievelijk 18 uren. Voor de werkende 61-64’ers en 65-pre-AOW’ers was hun financiële situatie een belangrijke drijfveer om door te werken. De werkende 61-64’ers en 65-pre-AOW’ers hadden minder gezondheidsbeperkingen dan de werkende post-AOW’ers, maar de werkende post-AOW’ers rapporteerden een hogere werkcapaciteit. De werkende 65-pre-AOW’ers vormden een minderheid van hun leeftijdsgenoten. Om te bevorderen dat meer mensen tot de AOW-leeftijd doorwerken, zeker aangezien deze hoger wordt, zouden de arbeidsomstandigheden beter aangepast moeten worden aan de werkcapaciteit in deze leeftijdsgroep.

Vitamin D plays an important role in skeletal health throughout life. Some studies have hypothesised that vitamin D may reduce the risk of other diseases. Our study aimed to estimate age-specific and sex-specific serum 25-hydroxyvitamin D (25(OH)D) status and to identify the determinants of serum 25(OH)D status in Hong Kong, a subtropical city in southern China. In 2009–2010, households in Hong Kong were followed up to identify acute respiratory illnesses, and sera from 2694 subjects were collected in three to four different study phases to permit measurement of 25(OH)D levels at different times of the year. A questionnaire survey on diet and lifestyle was conducted among children, with simultaneous serum collection in April and May 2010. The mean of serum 25(OH)D levels in age groups ranged from 39 to 63 nmol/l throughout the year with the mean values in all age groups in spring below 50 nmol/l. Children aged 6–17 years, and girls and women had significantly lower serum 25(OH)D levels than adults, and boys and men, respectively (allP< 0·001). We estimated that serum 25(OH)D levels in Hong Kong followed a lagged pattern relative to climatic season by 5 weeks with lowest observed levels in early spring (March). For children aged 6–17 years, reporting a suntan, having at least 1 servings of fish/week and having at least 1 serving of eggs/week were independently associated with higher serum 25(OH)D levels. Adequate sunlight exposure and increased intake of dietary vitamin D could improve vitamin D status, especially for children and females in the winter and spring.
