Changes in prolonged sedentary behaviour across the transition to retirement

Area of Science:

• Gerontology
• Public Health
• Occupational Health

Background:

• Prolonged sedentary behavior is a known risk factor for cardiometabolic diseases.
• Understanding changes in sedentary time during life transitions like retirement is crucial for public health.
• This study investigates sedentary time shifts around retirement, considering gender and occupation.

Purpose of the Study:

• To examine changes in daily total, prolonged (≥30 min), and highly prolonged (≥60 min) sedentary time.
• To analyze these changes across the transition to retirement.
• To explore differences by gender and occupational status.

Main Methods:

• Longitudinal study of 689 aging workers (Finnish Retirement and Aging Study - FIREA).
• Annual sedentary time measurement using wrist-worn ActiGraph accelerometers (3.4 measurement points on average).
• Data collected before and after retirement.

Main Results:

• Women significantly increased total sedentary time (+22 min), prolonged sedentary time (+34 min), and highly prolonged sedentary time (+15 min) post-retirement.
• Women retiring from manual occupations showed the largest increases in sedentary time.
• Men had higher overall sedentary time than women, with a gradual increase in prolonged sedentary time post-retirement (+33 min).

Conclusions:

• Retirement transition leads to abrupt increases in prolonged sedentary time for women and gradual increases for men.
• The retirement period presents a critical window for interventions to mitigate sedentary behavior.
• Addressing sedentary behavior during retirement is vital for long-term health and preventing cardiometabolic diseases.
