In: Acta Paediatrica. - : John Wiley & Sons. - 0803-5253 .- 1651-2227. ; 110:11, s. 3097-3104
Journal article (peer-reviewed) abstract
AIM: The aim of this study was to investigate self-reported physical activity and sedentary behaviour by sex, age and parental education in a large representative sample of Swedish adolescents.METHODS: This study is based on data from the national dietary survey Riksmaten Adolescents that was conducted by the Swedish Food Agency in 2016-2017. In total, 3477 students in grade five (11-12 years), eight (14-15 years), and eleven (17-18 years) were included. A web questionnaire was used to collect information about physical activity and sedentary behaviour.RESULTS: In total, 53% reported active transport to and from school, 93% that they usually participate in the physical education, 76% reported a physically active leisure time, and 66% that they participated in organised physical activities. In addition, 12% and 6% reported two hours or less of screen time on weekdays and weekends, respectively. Participation in physical activity was generally lower among girls, older adolescents and for those from families with low parental education.CONCLUSION: This study provide reference values for self-reported physical activities and sedentary behaviours among adolescents in Sweden. Strategies to increase physical activity and reduce screen time are needed, particularly among girls, older adolescents and among those with low parental education.

An eHealth program versus a standard care supervised health program and associated health outcomes in individuals with mobility disability : study protocol for a randomized controlled trial.
2018
In: Trials. - : Springer Science and Business Media LLC. - 1745-6215. ; 19:1
Journal article (peer-reviewed) abstract
BACKGROUND: Young adults with mobility disability (MD) are less likely to engage in regular physical activity (PA) compared with their able-bodied peers and inactive adults with a MD are more likely to report one or more chronic diseases compared to those who are physically active. Despite the vast amount of research published in the field of PA interventions over the past decades, little attention has been focused on interventions aiming to increase PA among individuals with MD. Thus, we propose to compare the effects of an eHealth program compared to a usual care supervised health program on levels of PA and other health behaviors.METHODS: The current intervention will use a randomized controlled trial (RCT) design with two treatment groups (an eHealth program and a usual care supervised health program) in young adults with newly acquired MD. In total, 110 young adults (aged 18-40 years) with a MD, acquired within the past 3 years, will be recruited to participate in a 12-week intervention. The primary study outcome is accelerometer-measured time spent in moderate to vigorous PA. Secondary outcomes includes health-related quality of life, depression, stress, fitness, body composition, diet, musculoskeletal pain, motivation to exercise and work ability.DISCUSSION: There is a lack of RCTs investigating effective ways to increase levels of PA in young adults with MD. Increased levels of PA among this physically inactive population have the potential to substantially improve health-related outcomes, possibly more so than in the general population. The trial will put strong emphasis on optimizing exercise adherence and investigating feasibility in the two treatment programs. The Ethical Review Board (EPN) at Karolinska Institutet has approved the study (2017/1206-31/1).TRIAL REGISTRATION: International Standard Randomised Controlled Trial Number (ISRCTN), reference number ISRCTN22387524 .

Perspectives on exercise intensity, volume, step characteristics and health outcomes in walking for transport
2022
In: Frontiers in Public Health. - : Frontiers Media S.A.. - 2296-2565. ; , s. 1-19
Journal article (peer-reviewed) abstract
Background: Quantification of movement intensity and energy utilization, together with frequency of trips, duration, distance, step counts and cadence, is essential for interpreting the character of habitual walking for transport, and its potential support of health. The purpose of the study is to illuminate this with valid methods and novel perspectives, and to thereby provide a new basis for characterizing and interpreting walking in relation to health outcomes.Methods: Habitual middle-aged commuting pedestrians (males = 10, females= 10) were investigated in the laboratory at rest and with maximal treadmill and cycle ergometer tests. Thereafter, levels of oxygen uptake, energy expenditure, ventilation, heart rate, blood lactate, rated perceived exertion, cadence, number of steps, duration, distance, and speed were recorded during the normal walking commute of each participant in Greater Stockholm, Sweden. The number of commutes per week over the year was self-reported.Results: Walking in the field demanded about 30% more energy per km compared to level treadmill walking. For both sexes, the walking intensity in field was about 46% of maximal oxygen uptake, and energy expenditure amounted to 0.96 kcal · kg−1 · km−1. The MET values (males: 6.2; females:6.5) mirrored similar levels of walking speed (males: 5.7; females: 5.9 km · h−1) and levels of oxygen uptake (males: 18.6; females: 19.5mL · kg−1 · min−1). The average number of MET-hours per week in a typical month was 22 for males and 20 for females. This resulted in a total weekly energy expenditure of∼1,570 and 1,040 kcal for males and females, respectively. Over the year, the number of walking commutes and their accumulated distance was ∼385 tripsand 800 km for both sexes.Conclusion: Walking in naturalistic field settings demands its own studies. When males and females walk to work, their relative aerobic intensities and absolute energy demands for a given distance are similar. It is equivalent to the lower part of the moderate relative intensity domain.The combination of oxygen uptake, trip duration and frequency leads to high and sustained levels of MET-hours as well as energy expenditure per week over the year, with a clear health enhancing potential. Based on this study we recommend 6000 transport steps per day, or equivalent, during five weekdays, over the year, in order to reach optimal health gains.

Re-examination of accelerometer data processing and calibration for the assessment of physical activity intensity.
2019
In: Scandinavian Journal of Medicine and Science in Sports. - : John Wiley & Sons. - 0905-7188 .- 1600-0838. ; 29:10, s. 1442-1452
Journal article (peer-reviewed) abstract
This review reexamines use of accelerometer and oxygen uptake data for assessment of activity intensity. Accelerometers capture mechanical work, while oxygen uptake captures the energy cost of this work. Frequency filtering needs to be considered when processing acceleration data. A too restrictive filter attenuates the acceleration signal for walking and, to a higher degree, for running. This measurement error affects shorter (children) more than taller (adults) individuals due to their higher movement frequency. Less restrictive filtering includes more movement related signals and provide measures that better capture mechanical work, but may include more noise. An optimal filter cut-point is determined where most relevant acceleration signals are included. Further, accelerometer placement affects what part of mechanical work being captured. While the waist placement captures total mechanical work and therefore contributes to measures of activity intensity equivalent by age and stature, the thigh and wrist placements capture more internal work and do not provide equivalent measures. Value calibration of accelerometer measures is usually performed using measured oxygen uptake with the metabolic equivalent of task (MET) as reference measure of activity intensity. However, the use of MET is not stringent and is not a measure of activity intensity equivalent by age and stature. A candidate measure is the mass-specific net oxygen uptake, VO2 net (VO2 tot - VO2 stand). To improve measurement of physical activity intensity using accelerometers, research developments are suggested concerning processing of accelerometer data, use of energy expenditure as reference for activity intensity, and calibration procedure with absolute versus relative intensity.

Accelerometer derived physical activity patterns in 27.890 middle‐aged adults : The SCAPIS cohort study
2022
In: Scandinavian Journal of Medicine and Science in Sports. - : John Wiley & Sons. - 0905-7188 .- 1600-0838. ; 32:5, s. 866-880
Journal article (peer-reviewed) abstract
The present study aims to describe accelerometer-assessed physical activity (PA) patterns and fulfillment of PA recommendations in a large sample of middle-aged men and women, and to study differences between subgroups of socio-demographic, socio-economic, and lifestyle-related variables. A total of 27 890 (92.5% of total participants, 52% women, aged 50–64 years) middle-aged men and women with at least four days of valid hip-worn accelerometer data (Actigraph GT3X+, wGT3X+ and wGT3X-BT) from the Swedish CArdioPulmonary bioImage Study, SCAPIS, were included. In total, 54.5% of daily wear time was spent sedentary, 39.1% in low, 5.4% in moderate, and only 0.1% in vigorous PA. Male sex, higher education, low financial strain, born in Sweden, and sedentary/light working situation were related to higher sedentary time, but also higher levels of vigorous PA. High BMI and having multiple chronic diseases associated strongly with higher sedentary time and less time in all three PA intensities. All-year physically active commuters had an overall more active PA pattern. The proportion fulfilling current PA recommendations varied substantially (1.4% to 92.2%) depending on data handling procedures and definition used. Twenty-eight percent was defined as having an “at-risk” behavior, which included both high sedentary time and low vigorous PA. In this large population-based sample, a majority of time was spent sedentary and only a fraction in vigorous PA, with clinically important variations between subgroups. This study provides important reference material and emphasizes the importance of a comprehensive assessment of all aspects of the individual PA pattern in future research and clinical practice.

Increasing physical activity through an adapted web-based exercise program for people with intellectual disabilities : Support staff are crucial for feasibility
2024
In: JARID. - : John Wiley & Sons. - 1360-2322 .- 1468-3148. ; 37:2
Journal article (peer-reviewed) abstract
BackgroundPeople with intellectual disabilities are less physically active and suffer from ill-health more than the general population. Support staff play an important role in the person's life. This study aimed to explore the support staff's experiences regarding the feasibility of adapted web-based exercise for people with intellectual disabilities.MethodParticipants with intellectual disabilities living in community-based settings were recruited for a web-based exercise study. Eight semi-structured interviews were carried out with their support staff before and after the intervention period.ResultsThe main theme, ‘Support staff are crucial for feasibility’ encompasses the importance of communication, structure, and motivation in improving physical activity for people with intellectual disabilities.ConclusionThe experiences of support staff, indicate that a web-based exercise program is feasible for the target group, and one way to overcome challenges for PA, where the role of the staff is crucial.

Alcohol Consumption Over the Retirement Transition in Sweden : Different Trajectories Based on Education
2022
In: Work, Aging and Retirement. - : Oxford University Press. - 2054-4642 .- 2054-4650. ; 8:1, s. 74-81
Journal article (peer-reviewed) abstract
Retirement is a major life transition that involves changes to everyday routines, roles, and habits. Previous studies suggest that retirement may influence drinking habits. Many natural inhibitors of alcohol consumption disappear with the removal of work constraints. The potential impact depends on both individual and contextual factors. Women in the cohorts undergoing retirement now have been more active on the labor market, including the occupation of higher status jobs, which indicates more financial resources as well as a larger role loss after retirement. Also, the current cohorts who retire have had more liberal drinking habits throughout their lives compared to previous cohorts. We therefore examined changes in alcohol consumption surrounding retirement in different education groups among women and men undergoing retirement using annual data from the Health, Aging and Retirement Transitions in Sweden (HEARTS) study, a longitudinal national study of 60- to 66-year-olds (n = 5,913), from 2015 to 2018. Latent growth curve models were used to estimate trajectories of alcohol consumption. Results showed that those who retired during the follow-up increased their usual weekly alcohol consumption while those who worked or were retired throughout the period had stable drinking habits. Those who were retired reported the highest alcohol consumption. The increase surrounding retirement was driven by people with higher education. Women with tertiary education and men with intermediate or tertiary education increased their weekly alcohol intake after retirement, while those with low education had unchanged drinking habits. Mechanisms and motivations that may fuel increased alcohol intake among people with higher education should be further investigated.

Leisure-time organised physical activity and dietary intake among Swedish adolescents.
2022
In: Journal of Sports Sciences. - : Routledge. - 0264-0414 .- 1466-447X. ; 40:11, s. 1198-1205
Journal article (peer-reviewed) abstract
This study aimed to investigate associations between participation in leisure-time organised physical activity (LTOPA) and dietary intake in a large representative sample of Swedish adolescents participating in the national dietary survey Riksmaten Adolescents 2016-2017. A sample of 2807 participants aged 11-12, 14-15 and 17-18 years were included. Information about LTOPA and dietary intake were collected through questionnaires and two 24-hour recalls on the web (RiksmatenFlex). For dietary intake, overall healthy eating index, intake of fruit, vegetables, candy, sugar-sweetened beverages, and the proportion of added sugar to total energy intake were analysed. Significance-testing for associations was performed with analysis of covariance. LTOPA was associated with lower sugar-sweetened beverages intake among adolescent boys (p < 0.001, ηp2 = 0.012) and girls (p = 0.007, ηp2 = 0.005), higher fruit intake among boys (p = 0.043, ηp2 = 0.003), and lower vegetable intake among girls (p < 0.001, ηp2 = 0.009). However, LTOPA was unrelated to the overall healthy eating index, candy intake, and the proportion of added sugar to total energy intake (p > 0.05). LTOPA was only associated with some healthy eating behaviours, and there is much room for improvement in the diets of Swedish adolescents.

The effectiveness of multi-component interventions targeting physical activity or sedentary behaviour amongst office workers : a three-arm cluster randomised controlled trial.
2020
In: BMC Public Health. - : BioMed Central (BMC). - 1471-2458. ; 20:1
Journal article (peer-reviewed) abstract
BACKGROUND: Interventions to increase physical activity or reduce sedentary behaviour within the workplace setting have shown mixed effects. This cluster randomised controlled trial assessed whether multi-component interventions, focusing on changes at the individual, environmental, and organisational levels, either increased physical activity or reduced sedentary behaviour, compared to a passive control group.METHODS: Teams of office-workers from two companies participated in one of two interventions (iPA: targeting physical activity; or iSED: targeting sedentary behaviour), or wait-list control group (C). Exclusion criterion was very high physical activity level (MVPA ≥30 min/day in ≥10 min bouts every day). Randomisation occurred at the level of workplace cluster, and groups were randomly allocated (1:1) with stratification for company and cluster size. Personnel involved in data collection and processing were blinded to group allocation. Both interventions included five sessions of cognitive behavioural therapy counselling for 6 months. iPA included counselling focused on physical activity, access to a gym, and encouragement to exercise, and go for lunch walks. iSED included counselling on sedentary behaviour and encouragement to reduce sitting and increase engagement in standing- and walking-meetings. At baseline and the 6-month mark accelerometers were worn on the hip and thigh for 7 days. The primary outcomes were group differences in time spent in moderate-to-vigorous intensity physical activity (%MVPA) and in sedentary behaviour (%), analysed using Bayesian multilevel modelling for those with complete data.RESULTS: Two-hundred and sixty three office workers (73% women, mean age 42 ± 9 years, education 15 ± 2 years) were randomised into 23 cluster teams (iPA n = 84, 8 clusters; iSED n = 87, 7 clusters; C n = 92, 7 clusters). No significant group differences (posterior mean ratios: 95% credible interval) were found after the intervention for %MVPA or for %Sedentary. %MVPA: iPA vs C (0·04: - 0·80-0·82); iSED vs C (0·47: - 0·41-1·32); iPA vs iSED (0·43: - 0·42-1·27). %Sedentary: iPA vs C (1·16: - 1·66-4·02); iSED vs C (- 0·44: - 3·50-2·64); iPA vs iSED (- 1·60: - 4·72-1·47).CONCLUSIONS: The multi-component interventions focusing on either physical activity or sedentary behaviour were unsuccessful at increasing device-measured physical activity or reducing sedentary behaviour compared to a control group.TRIAL REGISTRATION: ISRCTN, ISRCTN92968402 .

A national survey showed low levels of physical activity in a representative sample of Swedish adolescents.
2020
In: Acta Paediatrica. - : John Wiley & Sons. - 0803-5253 .- 1651-2227. ; 109:11, s. 2342-2353
Journal article (peer-reviewed) abstract
AIM: This study investigated objectively measured physical activity and sedentary time by sex, age and socioeconomic status in a large representative sample of Swedish adolescents.METHODS: In this cross-sectional national survey between 2016 and 2017, students aged 11-12, 14-15 and 17-18 years from 131 schools were invited to participate. Physical activity and sedentary time were measured objectively with accelerometers for seven consecutive days. Socioeconomic status (parental education) and country of birth were self-reported in a questionnaire. Weight and height were measured by trained staff.RESULTS: A total of 3477 adolescents participated in the study, and 2419 (73%) had at least 3 days of valid accelerometer data. The results showed that 43% of boys and 23% of girls reached the recommendation of 60 minutes of daily moderate-to-vigorous physical activity. Boys were more physically active than girls in all age groups. Girls with high socioeconomic status were more physically active than girls with low socioeconomic status (P < .001), and this difference was not found in boys.CONCLUSION: The majority of Swedish adolescents did not reach the physical activity recommendation, and boys were more active than girls. Effective strategies to increase physical activity, especially among girls with low socioeconomic status, are urgently needed.
