Adverse Clinical Events and Mortality During Hospitalization and 3 Months After Discharge in Cognitively Impaired Elderly Patients
2012
BACKGROUND: Controversial findings are reported on hospital outcome in cognitively impaired patients. The aim of this study was to explore mortality risk according to cognitive status during hospitalization and after 3 months in elderly patients. METHODS: Sixty-six internal medicine and geriatric wards in Italy participated in the "Registry Politerapie SIMI (REPOSI)" during 2010. Of the 1,380 in-patients, aged 65 and older enrolled, 1,201 were included. Cognition was evaluated with the Short Blessed Test (SBT). Logistic regression was used to evaluate the association of questionable and impaired cognition (according to SBT cutoff points) with mortality during hospitalization and at follow-u…
Effects of persistent physical activity and inactivity on coronary risk factors in children and young adults. The Cardiovascular Risk in Young Finns …
1994
The tracking of physical activity and its influence on selected coronary heart disease risk factors were studied in a 6-year (original survey in 1980, with follow-ups in 1983 and 1986) study of Finnish adolescents and young adults as part of the Cardiovascular Risk in Young Finns Study. The subjects in this analysis were aged 12, 15, and 18 years at baseline. Physical activity was assessed with a standardized questionnaire, and a sum index was derived from the product of intensity, frequency, and duration of leisure time physical activity. Complete data on physical activity index from each study year were available on 961 participants. Significant tracking of physical activity was observed …
Physical activity and obesity mediate the association between childhood motor function and adolescent's academic achievement
2013
The global epidemic of obesity and physical inactivity may have detrimental implications for young people’s cognitive function and academic achievement. This prospective study investigated whether childhood motor function predicts later academic achievement via physical activity, fitness, and obesity. The study sample included 8,061 children from the Northern Finland Birth Cohort 1986, which contains data about parent-reported motor function at age 8 y and self-reported physical activity, predicted cardiorespiratory fitness (cycle ergometer test), obesity (body weight and height), and academic achievement (grades) at age 16 y. Structural equation models with unstandardized (B) and standardi…
Number of meals eaten in relation to weight status among Norwegian adolescents.
2010
Aim: To assess the relationship between number of meals eaten and weight status, and to assess potential confounders of this relationship. Methods: A total of 2870 (participation rate: 85%) 9th and 10th graders (mean age: 15.5 years) at 33 schools completed questionnaires in May 2005. Number of meals was measured with questions asking whether they ate breakfast, lunch, dinner, and supper the day before, giving a scale ranging from zero to four meals/day. Data on gender, height, weight, education plans, intake of fruits and vegetables, consumption of unhealthy snacks, TV/computer time, physical activity level, and dieting were also collected. Results: The proportions of overweight adolescen…
Oxidative stress is associated with an increased antioxidant defense in elderly subjects: a multilevel approach.
2014
© 2014 Fonseca et al. Background: Studies of associations between plasma GSH-Px activity and cardiovascular risk factors have been done in humans, and contradictory results have been reported. The aim of our study was to assess the association between the scavenger antioxidant enzyme glutathione peroxidase (GSH-Px) activity in plasma and the presence of novel and classical cardiovascular risk factors in elderly patients. Copyright: Methods: We performed a cross-sectional study with baseline data from a subsample of the PREDIMED (PREvención con DIeta MEDiterránea) study in Spain. Participants were 1,060 asymptomatic subjects at high risk for cardiovascular disease (CVD), aged 55 to 80, selec…
Difficulties in mobility among elderly people and their association with socioeconomic factors, dwelling environment and use of services.
1995
The purpose of this study was to clarify the extent to which elderly people have difficulties in mobility, and determine their association with socioeconomic factors, dwelling environment and use of services. The study groups were composed of two random samples of 800 persons aged 65–74 and 75–84, respectively. In all, 1224 non- institutionalized persons (80%) were interviewed at home. The respondents were asked to assess their ability to get about the house, negotiate stairs and walk outdoors, as well as manage certain physical exercise tasks. Difficulties in getting about outdoors were found most frequently among the women in the older age group (52% reported difficulties), and least freq…
The relationship between different settings of medical service and incident frailty
2018
Background: Some studies have reported a potential association between usual source of health care and disability, but no one has explored the association with frailty, a state of early and potential reversible disability. We therefore aimed to explore the association between older persons' self-reported usual source of health care at baseline and the onset of frailty. Methods: Information regarding usual source of health care was captured through self-report and categorized as 1) private doctor's office, 2) public clinic, 3) Health Maintenance Organization (HMO), or 4) hospital clinic/emergency department (ED). Frailty was defined using the Study of Osteoporotic Fracture (SOF) index as the…
Physical Activity Among Adolescents With Long-Term Illnesses or Disabilities in 15 European Countries.
2017
Physical activity (PA) is an important health-promoting behavior from which adolescents with long-term illnesses or disabilities (LTID) can benefit. It is important to monitor differences across countries in adherence with PA recommendations for health. The aim of this study was to compare PA levels among 15 European countries after disaggregating data by disability. Data from pupils (mean age = 13.6 years, SD = 1.64) participating in the 2013/2014 Health Behavior in School-aged Children study were analyzed to compare adolescents without LTID, with LTID, and with LTID that affects their participation (affected LTID). Logistic regression models adjusted for age and family affluence, stratifi…
Quality of life (QOL) of older adult community choral singers in Finland.
2013
ABSTRACTBackground: Enhancing quality of life (QOL) of older adults is an international area of focus. Identifying factors and experiences that contribute to QOL of older adults helps promote optimal levels of functioning. This study examines the relationship between perceived benefits associated with choral singing and QOL among community-dwelling older adults.Methods: One hundred seventeen older adults who sing in community choirs in Jyväskylä, Finland, completed self-report measures of QOL (WHOQOL-Bref), depressive symptoms, and a questionnaire about the benefits of singing in choir. Correlational analyses and linear regression models were used to examine the association between the bene…
Oral health care activities performed by caregivers for institutionalized elderly in Barcelona-Spain
2013
Objectives: To describe the frequency of brushing teeth and cleaning of dentures, performed by caregivers, for institutionalized elderly people. Methods: A cross-sectional study in a sample of 196 caregivers of 31 health centers in Barcelona. The dependent variables were frequency of dental brushing and frequency of cleaning of dentures of the elderly by caregivers. The independent variables were characteristics of caregivers and institutions. We performed bivariate and multivariate descriptive analyses. Robust Poisson regression models were fitted to determine factors associated with the dependent variables and to assess the strength of the association. Results: 83% of caregivers were wome…
