OBJECTIVE: Sedentary behavior (SB) is defined as a mean of >6 hours of daytime sitting or lying down. SB has been shown to increase with older age and is a risk factor for disease. During the transition from working life to retirement, changes in daily life activities occur, risking increased SB. The aim of the present study was to gain a deeper understanding of SB in relation to the transition from working life to retirement as experienced by persons in retirement.

METHODS: The study was grounded in a phenomenological life-world perspective. Fourteen semi-structured interviews were conducted with participants aged 64-75. Data were analyzed using the empirical phenomenological psychological method.

RESULTS: The participants described that voluntary sedentary time was positively related to general health and well-being, while involuntary sedentary time was negatively related to health. Increased sedentary time was described as natural when aging. Retirement was expressed as a time for rest after hard work and the ability to choose a slower pace in life. Internal and external demands and daily routines interrupted SB, whereas loneliness was perceived to increase SB. Participants strived to find a balance between physical activity and sedentary time. The variations in the participants' descriptions formed three typologies: in light of meaningful sedentary behavior, in the shadow of involuntary sedentary behavior, and a dual process - postponing sedentary behavior with physical activity.

CONCLUSIONS: Increased SB was perceived as natural when aging, but something that may be postponed by conscious choices. SB was perceived as associated with health, rest and recovery but also with the risk of deteriorating health.

IMPACT: This knowledge of the experienced meaning of SB could guide the design of health promotion interventions and may be helpful in targeting those in need of support and individualizing interventions to decrease SB in retirement.

LAY SUMMARY: This study reveals how persons in retirement describe sedentary behavior as something healthy but also as unhealthy and that sedentary behavior is natural in aging and can be postponed by physical activity.
