Biking to School: The Role of Bicycle-Sharing Programs in Adolescents
2016
BACKGROUND The purpose of this study was to: (1) describe modes of transport to school, with a specific focus on the use of public bicycle share programs (PBSP); and (2) assess sociodemographic, psychosocial, and environmental correlates of bike and PBSP use to go to school. METHODS A group of 465 adolescents from the International Physical Activity and the Environment Network (IPEN) Adolescent Study (Valencia, Spain) participated in the research. Mixed regression analyses were conducted on the data obtained. RESULTS Not having bicycle access, a PBSP card, or a public bike lane close to the school is negatively associated with bicycle use. PBSP is positively associated with physical self-ef…
Effectiveness of School-Initiated Physical Activity Program on Secondary School Students' Physical Activity Participation
2013
BACKGROUND The promotion of physical activity and health has become a universal challenge. The Sotkamo Physical Activity as Civil Skill Program was implemented to increase students' physical activity by promoting supportive psychological and physical school environment. The aim of this study was to evaluate the effectiveness of the school-initiated physical activity program on secondary school students' self-reported physical activity. METHODS The sample included 847 students (experimental condition school = 208, control school = 639) at the age of 12 to 14 years from northeast and central Finland. The program was conducted across 1 academic year and 2 measurement phases were carried out us…
Resting energy expenditure and body composition in morbidly obese, obese and control subjects
1994
Resting energy expenditure (REE) was investigated by indirect calorimetry in relation to body composition and to different degrees of obesity in order to assess if a defective energy expenditure contributes to extra body fat accumulation. Differences were found between control subjects (group C; BMI 23 +/- 0.5 kg/m2, REE 5890 +/- 218 kJ/day; mean +/- SEM) and obese subjects (group O; BMI 34.2 +/- 0.9 kg/m2, REE 7447 +/- 360 kJ/day; P0.0001) and between group C and morbidly obese subjects (group MO; BMI 49.9 +/- 1.6 kg/m2, REE 8330 +/- 360 kJ/day; P0.0001); REE was not significantly different between groups O and MO. Body composition data were obtained by means of body impedance analysis. Ev…
Big five and psychological and subjective well-being in Colombian older adults
2019
Abstract The goal of the current study was to investigate the relationships between the Five Factor Model of personality and the dimensions of subjective well-being (positive affect, negative affect, and life satisfaction), and psychological well-being (self-acceptance, personal growth, environmental mastery, autonomy, positive relations with others, and purpose in life). Participants included 618 Colombian adults aged 60–92 years. Multiple linear regression analyses were conducted. Regarding the subjective well-being, neuroticism was associated with lower scores on life satisfaction, and positively associated with negative affect, whereas extroversion and conscientiousness were associated …
Physical and psychological functioning of daily living in relation to physical activity. A longitudinal study among former elite male athletes and co…
2006
Background and aims: Physical exercise plays an important role in the prevention and reduction of disabilities in elderly people. The aim of this study was to determine the role of physical activity in the physical and psychological functioning of daily living in a cohort of former elite male athletes representing different sports, and controls of middle and old age. Methods: Subjects were 664 former elite male athletes (mean age 64.4 years) and 500 controls (62.0 years) in middle and old age. Subjects were mailed “Physical activity and health survey” questionnaires in 1985 and 1995. The primary outcomes — the physical and psychological functioning of daily living — were assessed in 1995 us…
Saccadic eye movements: what do they tell us about aging cognition?
2016
ABSTRACTAlthough the relationship between age-related cognitive decline and saccadic eye movement (SEM) deficits has been outlined, specific cognitive alterations underlying age-related changes in saccadic performance remain unclear. This study attempted to better understand the nature of aging effects on SEMs. We compared SEMs in younger and older adults in prosaccade (PS) and antisaccade (AS) tasks under gap, step, and overlap conditions. We also examined relationships between these performances and several neuropsychological scores. Twenty-eight younger adults (YA), 24 older adults under 65 years (OA 65) of age completed a neuropsychological evaluation, PS and AS tasks. Our results showe…
How does early developmental assessment predict academic and attentional-behavioural skills at group and individual levels?
2009
The main aim of the study was to explore the ability of a brief developmental assessment to predict teacher-rated learning and attentional and behavioural skills in the first grade of school at both the group and individual levels. A sample of 394 children (181 males, 213 females) aged 4 years were followed to the age of 6 years, and 283 of the children (145 males, 138 females; mean age 7 y 11 mo) were followed further to the first grade (age 7 y) at school. The children were administered a brief but comprehensive developmental assessment (Lene - a neurodevelopmental screening method) at their local child health-care centres at ages 4 and 6 years. In the first grade, teachers completed a de…
Diaschisis-Like Association of Hippocampal Atrophy and Posterior Cingulate Cortex Hypometabolism in Cognitively Normal Elderly Depends on Impaired In…
2017
Hippocampal atrophy and hypometabolism of the posterior cingulate cortex (PCC), early markers of Alzheimer's disease (AD), have been shown to be associated in late mild cognitive impairment and early AD via atrophy of connecting cingulum fibers. Recently, a direct association of hippocampal atrophy and PCC hypometabolism has been shown in cognitively normal elderly. We aimed to investigate if this association might be modulated by partly non-hippocampogenic alterations of parahippocampal cingulum (PHC) integrity. 45 cognitively healthy elderly aged 59 to 89 years were included from the Alzheimer's Disease Neuroimaging Initiative. Hippocampal volumes and PCC glucose metabolism were measured …
Balance confidence and functional balance are associated with physical disability after hip fracture.
2012
Abstract Background This cross-sectional study investigated the associations between balance confidence, functional balance, and physical disability among older people after hip fracture. Material and methods The study utilizes baseline data of two randomized controlled trials (ISRCTN34271567 and ISRCTN53680197). The participants were 159 community-dwelling over 60-year-old people. Health, fracture status, the date and type of surgery, and contraindications for participation were assessed in a clinical examination. Balance confidence was assessed by the Activities-specific Balance Confidence Scale (ABC) and functional balance by the Berg Balance Scale. Physical disability was assessed by a …
Common variants of the liver fatty acid binding protein gene influence the risk of type 2 diabetes and insulin resistance in Spanish population.
2012
Journal Article; Research Support, Non-U.S. Gov't; SUMMARY The main objective was to evaluate the association between SNPs and haplotypes of the FABP1-4 genes and type 2 diabetes, as well as its interaction with fat intake, in one general Spanish population. The association was replicated in a second population in which HOMA index was also evaluated. METHODS 1217 unrelated individuals were selected from a population-based study [Hortega study: 605 women; mean age 54 y; 7.8% with type 2 diabetes]. The replication population included 805 subjects from Segovia, a neighboring region of Spain (446 females; mean age 52 y; 10.3% with type 2 diabetes). DM2 mellitus was defined in a similar way in b…
