Epizootic cutaneous papillomatosis, cortisol and male ornamentation during and after breeding in the roach Rutilus rutilus.
2004
The prevalence of epidermal papillomatosis in roach is known to peak during the spawning period and to be higher in males than in females. The high occurrence of papillomatosis in polluted waters suggests that stress may contribute to the outbreak of the disease. However, little is known about breeding-induced stress in fish and its relationship with diseases. In this study, plasma cortisol concentration, hematocrit and the relative size of the spleen were determined in healthy and diseased male and female roach Rutilus rutilus during and shortly after spawning in a wild population. In addition, the sexual ornamentation (breeding tubercles on the lateral sides and on the frontal) of male ro…
Chernobyl exposure as stressor during pregnancy and hormone levels in adolescent offspring
2008
Background: Animal research suggests a programming effect of prenatal stress in the fetal period, resulting in disruptions in behavioural and neuromotor development. Physiological changes that mediate these effects include alterations in the hypothalamic-pituitary-adrenal axis and in testosterone levels. This human study focuses on changes related to these physiological systems after prenatal stress exposure. Methods: We examined the potential effect of prenatal stress associated with the Chernobyl disaster in an ongoing genetic epidemiological study in Finland. One birth cohort of twins (n = 121 twin pairs) was exposed in utero to maternal stress, and their saliva cortisol and testosterone…
Intraocular pressure in samples of elderly Finnish and Swedish men and women.
1994
Abstract Intraocular pressure was measured in 231 systematically sampled 75-year-old men and women in Goteborg, Sweden and in 284 75-year-old and 201 80-year-old residents in Jyvaskyla, Finland as part of a comparative study on functional capacity and health, NORA 75 (Nordic Research on Ageing). After excluding the cases reporting glaucoma in their medical history or using drugs for glaucoma treatment there were no significant differences in the distributions of intraocular pressure between the men (mean intraocular pressure in the right eye 15.1 mmHg, left eye 15.0 mmHg) and women (mean intraocular pressure in the right eye 15.5 mmHg, left eye 15.8 mmHg) in Goteborg. In Jyvaskyla the 75-ye…
Early-onset depressive disorders predict the use of addictive substances in adolescence: a prospective study of adolescent Finnish twins
2008
Aims To explore the developmental relationships between early-onset depressive disorders and later use of addictive substances. Design, setting and participants A sample of 1545 adolescent twins was drawn from a prospective, longitudinal study of Finnish adolescent twins with baseline assessments at age 14 years and follow-up at age 17.5 years. Measurements At baseline, DSM-IV diagnoses were assessed with a professionally administered adolescent version of Semi-Structured Assessment for Genetics of Alcoholism (C-SSAGA-A). At follow-up, substance use outcomes were assessed via self-reported questionnaire. Findings Early-onset depressive disorders predicted daily smoking [odds ratio (OR) …
Lifetime physical activity and cancer incidence—A cohort study of male former elite athletes in Finland
2013
Abstract Objectives Physical activity has been shown to decrease the risk of certain cancers. Objective of this study was to assess the effect of physical activity on cancer incidence in former male athletes in older age. Design A cohort of 2448 elite male athletes and 1712 referents was followed-up for cancer incidence during 1986–2010 through the Finnish Cancer Registry. Methods Standardised incidence ratios were calculated with the general male population as the reference. Self-reported questionnaire-based data on covariates were used in Cox regression analyses comparing the risk of cancer in athletes and referents. Results The overall cancer incidence was lower in athletes than in the g…
Tobacco, Cannabis, and Other Illicit Drug Use Among Finnish Adolescent Twins: Causal Relationship or Correlated Liabilities?*
2010
Contains fulltext : 90566.pdf (Publisher’s version ) (Open Access) Objective: Among Finnish adolescent twins, we compared (a) a model that describes a direct impact of liability to tobacco use on cannabis and other illicit drug use with (b) a model that included a shared underlying liability for these substances. Furthermore, the extent to which genetic and environmental influences contribute to the covariation between liabilities to use these substances was examined. Method: Tobacco and illicit drug use were assessed at age 17.5 years. Twin data on 3,744 individuals were analyzed using standard biometrical methods. Two alternative multivariate models were fit and compared with Mx, a statis…
Physical activity as a preventive measure for coronary heart disease risk factors in early childhood.
2004
Physical activity causes acute physiological and long-term adaptive responses in the body. It is a protective factor for coronary heart disease (CHD) in adults. It has been assumed that children younger than 8 years of age may be in general active enough and there would be hardly any relationships between physical activity and CHD risk factors in early childhood. One hundred and fifty-five children (age 4-7 years) participated in this physical activity study during three consecutive years. Physical activity was examined twice a year with a special-purpose physical activity diary. CHD risk factors were measured during annual health care visits in the Specific Turku Coronary Risk-Factor Inter…
Associations between loneliness, depressive symptoms and perceived togetherness in older people.
2005
This study explores the associations of loneliness with depressive symptoms in a five-year follow-up and describes how the six dimensions of perceived togetherness explain loneliness and depressive symptoms at baseline. The data were collected on 207 residents of Jyväskylä, central Finland, who at baseline in 1990 were aged 80; and 133 residents who at follow-up in 1995 were aged 85. Loneliness was assessed using a questionnaire item with four preset response options, perceived togetherness using the Social Provisions Scale, and depressive symptoms using the CES-D scale. A recursive structural equation model showed that in women but not in men, depressive symptoms predicted more experiences…
Aerobic fitness, energy balance, and body mass index are associated with training load assessed by activity energy expenditure
2009
The present study examined whether activity energy expenditure related to body mass (AEE/kg) is associated with maximal aerobic fitness (VO(2max)), energy balance, and body mass index (BMI) during the 2 hardest weeks of the military basic training season (BT). An additional purpose was to study the accuracy of the pre-filled food diary energy intake. Energy expenditure (EE) with doubly labeled water, energy intake (EI), energy balance, and mis-recording was measured from 24 male conscripts with varying VO(2max). AEE/kg was calculated as (EE x 0.9-measured basal metabolic rate)/body mass. The reported EI was lower (P<0.001) than EE (15.48 MJ/day) and mis-recording of the pre-filled diary …
Relationships Between Physical Fitness, Demands of Flight Duty, and Musculoskeletal Symptoms Among Military Pilots.
2015
Although the mechanisms of G-induced stresses on the spinal structure of military pilots are well understood, less is known about relationships between the intensity of physical activity, fitness, occupational musculoskeletal symptoms, and the degree of resulting disabilities. During an aeromedical examination, Finnish military pilots answered a questionnaire on their flying experience, the occurrence of flight duty-related pain, the degree of resulting disabilities, and the intensity of physical activity they conducted. 195 males were selected for further analysis. They were divided into three groups, designated high G, low G, and HQ, according to their current flight duty profile. 93% of …
