Modifications of 24-h movement behaviors to prevent obesity in retirement: a natural experiment using compositional data analysis
Authors' conclusion
During the transition from work to retirement, increasing MVPA was associated with a slight decrease in BMI and waist circumference, whereas increasing sleep was associated with an increasing BMI. Common life transitions, like retirement, should be considered when giving recommendations and guidance for physical activity and sleep.
Study context
- Population
- Retiring public sector workers from the Finnish Retirement and Aging study; mean age 63.5 years (SD 1.1)
- Participants
- 213 workers
- Outcome
- Associations between one-year changes in 24-h movement behaviors (sleep, SED, LPA, MVPA) and concurrent changes in BMI and waist circumference
- Follow-up
- One year, before to after retirement
Methodological detailscompositional linear regression, isotemporal substitution analysis, thigh-worn accelerometer
- Compositional linear regression
- Isotemporal substitution analysis
- Thigh-worn accelerometer
Main finding
As reported in the abstract
one year from before to after retirement
- Increase in moderate-to-vigorous physical activity (MVPA) relative to sleep, SED and light physical activity (LPA): Body mass index (BMI) β (p = 0.04)
- −0.60
- Increase in MVPA relative to sleep, SED and LPA: waist circumference β (p = 0.05)
- −2.14
- Increase in sleep relative to SED, LPA and MVPA: BMI β (p = 0.02)
- 1.34
- Reallocating 60 min from MVPA to SED or sleep: estimated mean BMI increase
- 0.8-0.9 kg/m²
- Reallocating 60 min from MVPA to SED or sleep: estimated waist circumference increase
- 3.0 cm
Observational data: associations, not effects.
