Colour polymorphism torn apart by opposing positive frequency-dependent selection, yet maintained in space.
2015
Summary Polymorphic warning signals in aposematic species are enigmatic because predator learning and discrimination should select for the most common coloration, resulting in positive frequency‐dependent survival selection. Here, we investigated whether differential mating success could create sufficiently strong negative frequency‐dependent selection for rare morphs to explain polymorphic (white and yellow) warning coloration in male wood tiger moths (Parasemia plantaginis). We conducted an experiment in semi‐natural conditions where we estimated mating success for both white and yellow male moths under three different morph frequencies. Contrary to expectations, mating success was positi…
Life-course leisure-time physical activity trajectories in relation to health-related behaviors in adulthood: the Cardiovascular Risk in Young Finns …
2021
Background Evidence on whether leisure-time physical activity (LTPA) facilitates individuals’ adoption of multiple healthy behaviors remains scarce. This study investigated the associations of diverse longitudinal LTPA trajectories from childhood to adulthood with diet, screen time, smoking, binge drinking, sleep difficulties, and sleep duration in adulthood. Methods Data were drawn from the Cardiovascular Risk in Young Finns Study. Participants were aged 9–18 years (N = 3553; 51% females) in 1980 and 33–49 years at the latest follow-up in 2011. The LTPA trajectories were identified using a latent profile analysis. Differences in self-reported health-related behaviors across the LTPA trajec…
Limited indirect fitness benefits of male group membership in a lekking species
2014
In group living species, individuals may gain the indirect fitness benefits characterizing kin selection when groups contain close relatives. However, tests of kin selection have primarily focused on cooperatively breeding and eusocial species, whereas its importance in other forms of group living remains to be fully understood. Lekking is a form of grouping where males display on small aggregated territories, which females then visit to mate. As females prefer larger aggregations, territorial males might gain indirect fitness benefits if their presence increases the fitness of close relatives. Previous studies have tested specific predictions of kin selection models using measures such as …
Questionnaire-assessed moderate to vigorous physical activity of the Finnish youth in 1979-2005
2009
The purpose of the study was to investigate the time trend of questionnaire-assessed moderate to vigorous physical activity (MVPA) among 12-18-year-old Finnish boys and girls from 1979 to 2005. The MVPA was defined as "at least moderately breathtaking and sweating in leisure time physical activities more than 3 times week." Data were based on the Adolescent Health and Lifestyle Survey, which is a biannual, nation-wide survey on adolescent health and health-related lifestyle in Finland. The nationally representative samples were drawn from the Finnish Population Register Centre. The numbers of participants varied from 2832 to 8390 and the response rates from 91% (girls, 1981) to 58% (boys, 2…
Leisure‐time physical activity and participation in organized sports: Changes from 1985 to 2014 in Finland and Norway
2019
Participation in organized sports is a popular and important part of the lives of children and adolescents and is associated with improved psychological and social health, as well as an increased likelihood of meeting physical activity (PA) recommendations. Changes in modern society, including increased car ownership and use of technology and electronic media, have led to an additional focus on the importance of health‐enhancing PA among children and adolescents. The aim of this article was to study the secular changes in self‐reports of participation in organized sports clubs and leisure‐time vigorous physical activity (LVPA), and whether the relationship between participation in organized…
Adolescents' physical activity at recess and actions to promote a physically active school day in four Finnish schools
2014
The national Finnish Schools on the Move programme support schools with their individual plans to promote school-based physical activity (PA). We examined the changes in adolescents’ recess and overall PA in four lower secondary schools and described the school actions to promote students’ PA and the local contact persons’ perceptions of the effects. Recess and overall PA were assessed four times by anonymous questionnaires from students in grades 7–9 (n = 789) in 2010–12, and local contact persons (n = 7) provided information on school actions with diaries, interviews and surveys. Student data were analysed with descriptive statistics and chi-square tests, and school actions data were anal…
Personal goals and changes in life-space mobility among older people
2015
Abstract Objective Life-space mobility – the spatial extent of mobility in daily life – is associated with quality of life and physical functioning but may also be influenced by future orientation expressed in personal goals. The aim of this study was to explore how different personal goals predict changes in older people's life-space mobility. Methods This prospective cohort study with a 2-year follow-up included 824 community-dwelling people aged 75 to 90 years from the municipalities of Jyvaskyla and Muurame in Central Finland. As part of the Life-Space Mobility in Old Age study (LISPE), which was conducted between 2012 and 2014, the participants responded to the Life-Space Assessment an…
Barriers to outdoor physical activity and unmet physical activity need in older adults
2014
Abstract Objective To profile participants based on reported outdoor physical activity barriers using a data-driven approach, describe the profiles and study their association with unmet physical activity need. Method Cross-sectional analyses of 848 community-dwelling men and women aged 75–90 living in Central Finland in 2012. Barriers to outdoor physical activity and unmet physical activity need were enquired with a questionnaire. The latent profiles were identified by profiling participants into latent groups using a mixture modeling technique on the multivariate set of indicators of outdoor physical activity barriers. A path model was used to study the associations of the profiles with u…
Perceived and objective entrance-related environmental barriers and daily out-of-home mobility in community-dwelling older people
2017
Abstract Purpose We studied whether entrance-related environmental barriers, perceived and objectively recorded, were associated with moving out-of-home daily in older people with and without limitations in lower extremity performance. Methods Cross-sectional analyses of the “Life-space mobility in old age” cohort including 848 community-dwelling 75–90-year-old of central Finland. Participants reported their frequency of moving out-of-home (daily vs. 0–6 times/week) and perceived entrance-related environmental barriers (yes/no). Lower extremity performance was assessed (Short Physical Performance Battery) and categorized as poorer (score 0–9) or good (score 10–12). Environmental barriers at…
Physical Limitations, Walkability, Perceived Environmental Facilitators and Physical Activity of Older Adults in Finland
2017
The aim was to study objectively assessed walkability of the environment and participant perceived environmental facilitators for outdoor mobility as predictors of physical activity in older adults with and without physical limitations. 75–90-year-old adults living independently in Central Finland were interviewed (n = 839) and reassessed for self-reported physical activity one or two years later (n = 787). Lower-extremity physical limitations were defined as Short Physical Performance Battery score ≤9. Number of perceived environmental facilitators was calculated from a 16-item checklist. Walkability index (land use mix, street connectivity, population density) of the home environment was …
