Personal activity intelligence and mortality : Data from the Aerobics Center Longitudinal Study

2021

Importance Personal activity intelligence (PAI) is a novel activity metric that can be integrated into self-assessment heart rate devices, and translates heart rate variations during exercise into a weekly score. Previous studies relating to PAI have been conducted in the same populations from Norway where the PAI metric has been derived, limiting generalizability of the results. Objective To test whether PAI is associated with total and cause-specific mortality in a large cohort from the United States. Design Aerobics Center Longitudinal Study (ACLS) - a prospective cohort between January 1974 and December 2002 with a mean follow-up of 14.5 years. Setting Population-based. Participants 56,…

Job strain among blue-collar and white-collar employees as a determinant of total mortality: a 28-year population-based follow-up.

2012

Objectives To investigate the effect of job demand, job control and job strain on total mortality among white-collar and blue-collar employees working in the public sector. Design 28-year prospective population-based follow-up. Setting Several municipals in Finland. Participants 5731 public sector employees from the Finnish Longitudinal Study on Municipal Employees Study aged 44–58 years at baseline. Outcomes Total mortality from 1981 to 2009 among individuals with complete data on job strain in midlife, categorised according to job demand and job control: high job strain (high job demands and low job control), active job (high job demand and high job control), passive job (low job demand a…

Investigating occupational well-being and leadership from a person-centred longitudinal approach: congruence of well-being and perceived leadership

2015

The overall objective of this longitudinal study was to investigate the association between perceived leadership and employee well-being from a person-centred approach utilizing the principles of the conservation of resources theory (Hobfoll, S. E. (1989). Conservation of resources: A new attempt at conceptualizing stress. American Psychologist, 44, 513–524; Hobfoll, S. E. (2002). Social and psychological resources and adaptation. Review of General Psychology, 6, 307–324). First, we aimed to identify latent classes (i.e., subgroups) of employees that demonstrated similar mean levels of stability and change in occupational well-being (i.e., vigour and emotional exhaustion) across a mean time…

Unveiling the Mysteries of Dyslexia-Lessons Learned from the Prospective Jyväskylä Longitudinal Study of Dyslexia.

2021

This paper reviews the observations of the Jyväskylä Longitudinal Study of Dyslexia (JLD). The JLD is a prospective family risk study in which the development of children with familial risk for dyslexia (N = 108) due to parental dyslexia and controls without dyslexia risk (N = 92) were followed from birth to adulthood. The JLD revealed that the likelihood of at-risk children performing poorly in reading and spelling tasks was fourfold compared to the controls. Auditory insensitivity of newborns observed during the first week of life using brain event-related potentials (ERPs) was shown to be the first precursor of dyslexia. ERPs measured at six months of age related to phoneme length identi…

Reading comprehension from grade 1 to 6 in two shallow orthographies: comparison of Estonian and Finnish students

2018

The aim was to examine reading comprehension among elementary school students in two shallow orthographies, Estonian and Finnish. Participants were 619 Estonian children (50% boys) and 292 Finnish children (52% boys) whose reading comprehension was assessed in first, second, third, and sixth grades. The results showed that reading comprehension among Estonian and Finnish children was at a similar level by the end of first grade but Finnish children started to have better performance from second grade onward. These findings suggest that the roots of Finnish students’ strong reading skills are nurtured from the very beginning of elementary school. The potential cross-country differences in re…

Parental literacy predicts children’s literacy: A longitudinal family-risk study

2011

This family-risk (FR) study examined whether the literacy skills of parents with dyslexia are predictive of the literacy skills of their offspring. We report data from 31 child–parent dyads where both had dyslexia (FR-D) and 68 dyads where the child did not have dyslexia (FR-ND). Findings supported the differences in liability of FR children with and without dyslexia: the parents of the FR-D children had more severe difficulties in pseudoword reading and spelling accuracy, in rapid word recognition, and in text reading fluency than the parents of the FR-ND children. Finally, parental skills were found to be significant predictors of children's Grade 3 reading and spelling. Parental skills p…

Self-Concept, Body Image, and Perceived Health

2001

Studies of chronically ill adolescents have typically concentrated too much on social resources as factors that can buffer the effects of stress, while neglecting internal resources, such as self-concept and overall health (Cohen & Wills, 1985; Jamison, Lewis, & Burish, 1986). For a long time, studies on diabetic adolescents only focused on certain aspects of internal resources. Corresponding to studies carried out on adults with diabetes, much research concentrated on understanding the “diabetic personality” (Dunn & Turtle, 1981). It is surprising that so little consideration has been given to examining the role of the self-concept, because it is known that this internal resource is centra…

Normal-weight obesity and cardiometabolic risk: A 7-year longitudinal study in girls from prepuberty to early adulthood

2017

Objective To study whether normal-weight obesity in childhood is associated with increased cardiometabolic risk in early adulthood. Methods This study assessed data for 236 girls followed from prepuberty to early adulthood. Growth chart data were obtained from birth to 18 years. Body composition was assessed by dual-energy x-ray absorptiometry and cardiometabolic risk by calculating continuous clustered risk score (at ages 11, 14, and 18). The association of body weight status with cardiometabolic risk from childhood to early adulthood was examined. Results Subjects with normal-weight obesity were virtually indistinguishable from their normal-weight lean peers in terms of relative body weig…
