Age identification in the framework of successful aging. A study of older Finnish people.
2003
A person-oriented approach was used in a study of age identification among community-dwelling older people. The study was based on 8-year follow-up data; 843 persons aged 65–84 were involved in the first phase of the study, and 426 persons aged 73–92, in the second phase. Loosely, on the basis of the distinction between successful, usual, and pathological aging (Rowe & Kahn, 1987, 1997), participants were grouped according to their self-ratings of cognitive and physical functioning as “Positive,” “Negative,” and “Others.” Participants possessing at least 4 out of the 5 criteria used as indicators of successful aging in the study (no illness or injury presenting problems in daily life, …
Impact of sociodemographic characteristics on cognitive performance in an elderly Sicilian population.
2002
<i>Objective:</i> To assess cognitive levels in an elderly Sicilian population and to evaluate the role of education and other sociodemographic characteristics in cognitive performance. <i>Background:</i> The pattern of cognitive performance in the elderly has not been investigated extensively in well-defined Italian populations. This study was conducted as part of a door-to-door survey of common neurologic disorders (the Sicilian Neuro-Epidemiologic Study project). <i>Methods:</i> Thirteen physicians administered an Italian version of the Short Portable Mental Status Questionnaire (SPMSQ) to all subjects aged 50 years or older who, on November 1, 1987, r…
Implementation of the Frailty Index in hospitalized older patients: Results from the REPOSI register
2018
Abstract Background Frailty is a state of increased vulnerability to stressors, associated to poor health outcomes. The aim of this study was to design and introduce a Frailty Index (FI; according to the age-related accumulation of deficit model) in a large cohort of hospitalized older persons, in order to benefit from its capacity to comprehensively weight the risk profile of the individual. Methods Patients aged 65 and older enrolled in the REPOSI register from 2010 to 2016 were considered in the present analyses. Variables recorded at the hospital admission (including socio-demographic, physical, cognitive, functional and clinical factors) were used to compute the FI. The prognostic impa…
Prevalence and Risk Factors for Vitamin C Deficiency in North and South India: A Two Centre Population Based Study in People Aged 60 Years and Over
2011
BackgroundStudies from the UK and North America have reported vitamin C deficiency in around 1 in 5 men and 1 in 9 women in low income groups. There are few data on vitamin C deficiency in resource poor countries.ObjectivesTo investigate the prevalence of vitamin C deficiency in India.DesignWe carried out a population-based cross-sectional survey in two areas of north and south India. Randomly sampled clusters were enumerated to identify people aged 60 and over. Participants (75% response rate) were interviewed for tobacco, alcohol, cooking fuel use, 24 hour diet recall and underwent anthropometry and blood collection. Vitamin C was measured using an enzyme-based assay in plasma stabilized …
Cross-sectional assessment of nut consumption and obesity, metabolic syndrome and other cardiometabolic risk factors: the PREDIMED study
2013
INTRODUCTION: Prospective studies have consistently suggested that nut consumption is inversely related to fatal and non-fatal coronary heart disease. Limited data are available on the epidemiological associations between nut intake and cardiometabolic risk factors. OBJECTIVE: To evaluate associations between frequency of nut consumption and prevalence of cardiometabolic risk factors [obesity, metabolic syndrome (MetS), type-2 diabetes, hypertension, and dyslipidemia] in a Mediterranean population at high cardiovascular risk. MATERIALS AND METHODS: Cross-sectional study of 7,210 men and women (mean age, 67 y) recruited into the PREDIMED study. MetS was defined by the harmonized ATPIII and I…
Dietary magnesium intake is inversely associated with mortality in adults at high cardiovascular disease risk
2013
The relation between dietary magnesium intake and cardiovascular disease (CVD) or mortality was evaluated in several prospective studies, but few of them have assessed the risk of all-cause mortality, which has never been evaluated in Mediterranean adults at high cardiovascular risk. The aim of this study was to assess the association between magnesium intake and CVD and mortality risk in a Mediterranean population at high cardiovascular risk with high averagemagnesium intake. The present study included 7216 men and women aged 55-80 y fromthe PREDIMED (Prevencíon con Dieta Mediterŕanea) study, a randomized clinical trial. Participants were assigned to 1 of 2 Mediterranean diets (supplemente…
Vitamin D deficiency predicts cognitive decline in older men and women: The Pro.V.A. Study
2014
Objective: To test the hypothesis that hypovitaminosis D is associated with a higher risk of cognitive decline over a 4.4-year follow-up in a large sample of older adults. Methods: This research was part of the Progetto Veneto Anziani (Pro.V.A.), an Italian populationbased cohort study of 1,927 elderly subjects. Serum 25-hydroxyvitamin D (25OHD) levels were measured at the baseline. Global cognitive function was measured with the Mini-Mental State Examination (MMSE); scores lower than 24 were indicative of cognitive dysfunction, and a decline of 3 or more points on the MMSE over the follow-up was considered as clinically significant. Analyses were adjusted for relevant confounders, includin…
Espiritualidad en atención paliativa: Evidencias sobre la intervención con counselling
2015
ResumenLas necesidades espirituales, cuando son elaboradas de forma efectiva, ayudarán a la persona al final de la vida a encontrar significado, mantener la esperanza y aceptar la muerte. El counselling es una de las terapias más utilizadas para mejorar estas necesidades. El objetivo del presente trabajo es ofrecer evidencia sobre la eficacia de esta terapia para la mejora de la espiritualidad de los pacientes atendidos en diversos dispositivos de salud. Para conseguirlo, se llevó a cabo una intervención de tres semanas en 131 pacientes de atención domiciliaria y hospitalizados. Tenían una edad media de 70.61 años (DT = 11.17). El 51.1% eran hombres. Se evaluó la espiritualidad de los pacie…
Perception of quality of life in an elderly Angolan sample / Percepción de calidad de vida en una muestra de ancianos angoleños
2014
AbstractIncreased life expectancy and the ageing of the population have made it particularly important to distinguish between the old (usually 60–79 years, or the ‘young old’) and the oldest old (80 years or more, or the ‘fourth age’). This study explores the effects of age, gender and institutionalization on perceived health and life satisfaction in 1003 elderly people from Luanda, Angola. A multivariate analysis of variance (MANOVA) was estimated to test for these effects. Results provide evidence of lower scores on life satisfaction and perceived health for the oldest old and the institutionalized. However, the higher life satisfaction among the non-institutionalized disappeared when the…
Physical performance in relation to menopause status and physical activity
2018
Objective: The aim of this study was to examine differences in physical performance (muscle power, muscle strength, aerobic capacity, and walking speed) across menopausal stages and potential of leisure physical activity (PA) to modify the impact of menopause on physical performance. Methods: In this cross-sectional study, women aged 47 to 55 were randomly selected from the Finnish National Registry and categorized as premenopausal (n ¼ 233), perimenopausal (n ¼ 381), or postmenopausal (n ¼ 299) based on serum concentrations of follicle-stimulating hormone and bleeding diary. Physical performance was measured by knee extension force, handgrip force, vertical jumping height, maximal walking …
