EMG, heart rate, and accelerometer as estimators of energy expenditure in locomotion.
2014
AB Purpose: Precise measures of energy expenditure (EE) during everyday activities are needed. This study assessed the validity of novel shorts measuring EMG and compared this method with HR and accelerometry (ACC) when estimating EE. Methods: Fifty-four volunteers (39.4 +/- 13.9 yr) performed a maximal treadmill test (3-min loads) including walking with different speeds uphill, downhill, and on level ground and one running load. The data were categorized into all, low, and level loads. EE was measured by indirect calorimetry, whereas HR, ACC, and EMG were measured continuously. EMG from quadriceps (Q) and hamstrings (H) was measured using shorts with textile electrodes. Validity of the met…
Drinking, smoking, and educational achievement: Cross-lagged associations from adolescence to adulthood
2014
Background Adolescent substance use is associated with lower educational achievement but the directionality of the association remains uncertain. We analyzed data on drinking, smoking and educational achievement to study the associations between substance use and education from early adolescence to young adulthood. Methods Longitudinal data from four time points (ages 12, 14, 17, and 19–27 years) from a population-based cohort study of Finnish twin individuals were used to estimate bivariate cross-lagged path models for substance use and educational achievement, adjusting for sex, parental covariates, and adolescent externalizing behavior. A total of 4761 individuals (49.4% females) were in…
Musculoskeletal Pain in Melancholic and Atypical Depression
2016
Objective. Pain and depressive disorders often present together, but little is known about the prevalence of pain in depression subgroups. The objective of this study was to examine the possible differences in the prevalence of musculoskeletal pain between participants in melancholic and atypical depression subgroups. Design. Cross-sectional study. Setting. Depression nurse case managers where depression patients receive treatment in primary health care. Subjects. Participants included 413 depression patients and 401 controls. Methods. Depressive symptoms were determined with the Beck Depression Inventory (BDI-21), and diagnosis of depression was confirmed with the Mini-International Neurop…
From "Non-encounters" to autonomic agency. Conceptions of patients with low back pain about their encounters in the health care system.
2018
Low back pain is a considerable health problem which affects people around the world, causing major healthcare costs. The use of qualitative research methods enables us to describe and understand patients' experience of, and attitudes to, healthcare. The aim of the present phenomenographic study was to identify and describe the contextual nature of the conceptions of patients with low back pain of their encounters in the HCS. Seventeen patients with chronic or episodic low back pain classified as "high risk" were interviewed in open recall interviews, using videos of patients' initial physiotherapy sessions that had been recorded previously. The data were analysed using the phenomenographic…
Associations of parental physical activity trajectories with offspring's physical activity patterns from childhood to middle adulthood : The Young Fi…
2022
We investigated the association of parental physical activity (PA) trajectories with offspring's youth and adult PA. Self-reported PA data were extracted from the Young Finns Study with three follow-ups for parents between 1980 and 1986 and nine follow-ups for their offspring in youth between 1980 and 2011 (aged 9-39 years, n = 2402) and in adulthood in 2018. Accelerometer-derived PA was quantified in 2018-2020 (aged 43-58 years, n = 1134). Data were analyzed using mixture models and conducted in 2022. We identified three trajectories for fathers and mothers (high-stable activity, 20.2%/16.6%; moderate-stable activity, 50.5%/49.6%; and low-stable activity, 29.4%/33.7%) and four for youth ma…
The progression of myopia from its onset at age 8-12 to adulthood and the influence of heredity and external factors on myopic progression. A 23-year…
2013
Purpose To examine myopic progression and factors connected with myopic progression. Methods Myopic schoolchildren, with no previous spectacles, 119 boys and 121 girls, were recruited during 1983–1984 to a randomized 3-year clinical trial of bifocal treatment of myopia with a subsequent 20-year follow-up. Participants' mean age at Baseline was 10.9, ranging from 8.7 to 12.8 years. An ophthalmological examination was carried out annually for 3 years and twice thereafter at ca. 10-year intervals. Additional refraction values were received from prescriptions issued by different ophthalmologists and opticians. Altogether, 1915 refraction values were available. Reading distance and accommodation…
Relationship between mothers' enjoyment and sedentary behavior and physical activity of mother-child dyads using a movement-to-music video program : …
2020
Background: Parental support and participation in physical activity (PA) with children and parents' acting as a role model for less sedentary behaviors (SB) are critical factors for children's healthier lifestyle. The purpose of the study was to assess the relationship between mothers' enjoyment and participants' sedentary behavior (SB) and physical activity (PA) as a secondary analysis of a randomized controlled trial (RCT) using data from Moving Sound RCT in the Pirkanmaa area of Finland. Methods: The participants were 108 mother-child dyads (child age 5-7 years) who completed the eight-week exercise intervention using a movement-to-music video program in their homes. Mothers' enjoyment w…
Maternal body mass index in pregnancy and offspring physical and psychosocial functioning in older age: findings from the Helsinki Birth Cohort Study…
2016
Maternal obesity is associated with several adverse long-term health outcomes in the offspring. In this study, we examined the association between maternal body mass index (BMI) and offspring physical and psychosocial functioning in late adulthood.The study included 1759 men and women born during 1934-1944 and belonging to the Helsinki Birth Cohort Study. Data on maternal weight and height in late pregnancy and on offspring birth weight were retrieved from hospital birth records. Physical and psychosocial functioning was assessed using the Short Form 36 scale.Maternal BMI was positively associated with poorer physical and psychosocial functioning among men, but not among women. This associa…
Body size at birth and coronary heart disease-related hospital care in adult men : Findings from the Helsinki Birth Cohort Study
2017
Aim: We investigated, among those who had been hospitalized at least once due to coronary heart disease (CHD), the relationship between ponderal index (PI, birthweight/length3) at birth, a measure of thinness, and the age at first hospitalization due to CHD, the number of CHD-related hospital care episodes, and cost of CHD-related hospital care from young adulthood to old age. Methods and results: Data from the Helsinki Birth Cohort Study included 964 men born in Helsinki, Finland during 1934–1944, who had been hospitalized due to CHD and had birth anthropometrics data. PI (kg/m3) was categorized into low (27.5). CHD-related hospital care data were available from 1971 to 2013. We observed a…
Whole body frontal plane mechanics across walking, running, and sprinting in young and older adults
2016
This study investigated the whole body frontal plane mechanics among young (26 ± 6 years), early old (61 ± 5 years), and old (78 ± 4 years) adults during walking, running, and sprinting. The age-groups had similar walking (1.6 m/s) and running (4.0 m/s) speeds, but different maximal sprinting speed (young 9.3 m/s, early old 7.9 m/s, and old 6.6 m/s). Surprisingly, although the old group exerted much lower vertical ground reaction force during running and sprinting, the hip frontal plane moment did not differ between the age-groups. Kinematic analysis demonstrated increased hip adduction and pelvis drop, as well as reduced trunk lateral flexion among old adults, especially during sprinting. …
