Physical activity and dementia : Long-term follow-up study of adult twins
2015
Introduction. Physical activity is associated with a decreased occurrence of dementia. In twins, we investigated the effect of persistent physical activity in adulthood on mortality due to dementia. Materials and methods. Physical activity was queried in 1975 and 1981 from the members of the older Finnish Twin Cohort (n = 2 1,791), who were aged 24-60 years at the end of 1981. The subjects were divided into three categories according to the persistence of their vigorous physical activity. Dementia deaths were followed up to the end of 2011. Results. During the 29-year follow-up, 353 subjects died of dementia. In individual-based analyses the age-and sex-adjusted hazard ratio (HR) was 0.65 (…
Influence of comorbidity and cognitive status on instrumental activities of daily living in amnestic mild cognitive impairment: results from the ReGA…
2007
Objectives To investigate whether amnestic mild cognitive impairment (aMCI) is characterised by restriction in instrumental activities of daily living (IADL). Further, to examine the role of comorbidity and cognitive performance on IADL changes in aMCI subjects. Methods The study included 132 subjects with aMCI and 249 subjects with no cognitive impairment (NCI), consecutively enrolled as outpatients in a multicentric Italian clinical-based study, the ReGAl Project. All subjects underwent a comprehensive evaluation including clinical examination, laboratory screening, neuroimaging and cognitive and behavioral assessments. Functional status was evaluated by the Lawton's Instrumental Activiti…
Anxiety symptoms and mild cognitive impairment among community-dwelling older adults from low- and middle-income countries.
2021
Abstract Aim Anxiety may be a risk factor for mild cognitive impairment (MCI) but there is a scarcity of data on this association especially from low- and middle-income countries (LMICs). Thus, we investigated the association between anxiety and MCI among older adults residing in six LMICs (China, Ghana, India, Mexico, Russia, South Africa), and the mediational effect of sleep problems in this association. Methods Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. The definition of MCI was based on the National Institute on Ageing-Alzheimer's Association criteria. Multivariable logistic regression analy…
Low Hemoglobin Levels and the Onset of Cognitive Impairment in Older People: The PRO.V.A. Study
2016
Low hemoglobin (Hb) levels are attracting interest as a risk factor for cognitive impairment, but with contrasting evidence emerging from the current literature. The aim of our work was to investigate the relationship between baseline serum Hb levels and the incidence of cognitive impairment in older people over a follow-up of 4.4 years. Our study considered a sample of 1227 elderly subjects cognitively intact at baseline, enrolled under the Progetto Veneto Anziani (Pro.V.A.) among 3099 screened subjects. For all participants, we measured serum Hb levels on blood samples; incident cognitive impairment was defined as a Mini Mental State Examination (MMSE) score <24 and confirmed by geriat…
Psychometric properties of the Norwegian version of the Kidscreen-27 questionnaire
2016
Background The Norwegian version of the Kidscreen-27, a measure of generic health-related quality of life, has not yet been validated. Thus, the aim of this study was to investigate the reliability and validity of the Norwegian Kidscreen-27, in 10 year-old children. Methods The Kidscreen-27 consists of five domains and was validated in a cross-sectional study of 1085 school children (52.5 % boys). In addition a subsample of 56 children also had repeated measures in order to study test-retest reliability. Results Cronbach's alpha values ranged from 0.73 to 0.83, while intraclass correlation values over time ranged from 0.71 to 0.81. The domains of physical well-being, psychological well-bein…

Active Travel and Mild Cognitive Impairment among Older Adults from Low- and Middle-Income Countries
2021
Active travel may be an easily achievable form of physical activity for older people especially in low- and middle-income countries (LMICs), but there are currently no studies on how this form of physical activity is associated with a preclinical state of dementia known as mild cognitive impairment (MCI). Therefore, we aimed to investigate the association between active travel and MCI among adults aged ≥50 years from six LMICs. Cross-sectional, community-based data from the World Health Organization’s Study on Global Ageing and Adult Health were analyzed. The definition of MCI was based on the National Institute on Ageing-Alzheimer’s Association criteria. Active travel (minutes/week) was as…

The Reliability and Validity of Scores from the Children’S Version of the Perception of Success Questionnaire
1999
Recent research into achievement motivation in sports has focused on goal orientation theory, according to which task and ego goal orientations manifest themselves in achievement contexts and may have different cognitive and affective outcomes. The present study analyzed the reliability and validity of scores on the children’s version of the Perception of Success Questionnaire (POSQ-CH). The participants were 557 14-year-old Finnish male soccer players. Because the Task Orientation and Ego Orientation subscales were found to be orthogonal, we applied confirmatory factor analysis to the task and ego orientation items separately to evaluate the reliability and validity coefficients of the it…
