Background It is unknown whether reducing sedentary time at work and during leisure time is possible and effective during one year. Methods Office workers with young children were recruited for this one-year cluster-randomized controlled trial through kindergartens and primary schools from 7 clusters in the city of Jyväskylä, Finland. After a lecture, face-to-face tailored counseling was used to set contractually binding goals regarding reducing and breaking up sitting periods and increasing light intensity physical activity during work and leisure time. Primary outcomes of total, work and leisure sedentary time (<100 counts/min, cpm), light activity time (<2020 cpm), moderate-tovigorous activity time (MVPA) and breaks/sedentary hour were assessed with a waist-worn Alive -accelerometer for 7 days, 5 times during the year. Anthropometrics (DXA), fasting biomarkers and self-reported diet were assessed as secondary outcomes. Data were collected between 2011–2013 and analyzed between 2013–2016 with a linear mixed-effects model fit by REML using likelihood ratio test and intention-to-treat–principle. Results Participants from intervention (N = 71) and control (N = 62) regions were assessed at baseline and 117 completed the study. Sedentary leisure time decreased [-21.2 (95% CI -37.3 to -5.1) min/8 hours, likelihood ratio P<0.001] and light activity time [13.4 (-2.2 to 29.0) min/8 hours, P = 0.008] and breaks per sedentary hour [1.0 (-0.2 to 2.2), P = 0.010] increased in the intervention group as compared to controls at 3 months. The decrease in sedentary leisure time was maintained throughout the year [-7.9 (-24.0 to 8.3) min/8 hours, P = 0.029]. Small decreases in the control group’s work and leisure MVPA were observed mostly at 3 months. Small favorable intervention effects were observed for fasting plasma glucose at 3 months and for leg lean mass and apoB/apoA-1 ratio at 12 months, with no changes in other outcomes. Conclusions Behavioral counseling induced a small decline in sedentary leisure time throughout one year in parents with a sedentary occupation and young children. Small concurrent changes in different biomarkers suggest that reducing sedentary leisure time during one year may be beneficial. ...

Reduced muscle inactivity, sedentary time and cardio-metabolic benefits : effectiveness of a one-year family-based cluster randomized controlled trial Pesola, Arto (University of Jyväskylä, 2016)A driving hypothesis of the evolving field of sedentary behavior is that frequent muscle activity short-circuits detrimental physiological effects of sedentary time. However, the field relies mostly on observational ...
Leisure time physical activity, liver fat and cardio-metabolic risk factors : a monozygotic co-twin control and an observational study Giarmenitis, Dimitrios (2019)Introduction: Obesity has a strong link with cardio-metabolic risk factors. This fact has raised the necessity to understand the underlying causes of obesity for efficient prevention and treatment strategies. It has ...
