Results Against a background of complex changes there was an overall decrease in ST in young women(median change -0.48 hrs/day, interquartile range [IQR] =-2.54, 1.50) and an increase in ST in mid-aged women (median change 0.43 hrs/day; IQR =-1.29, 2.0) over nine years. In young women, returning to study and job loss were associated with increased ST, while having a baby, beginning work and decreased income were associated with decreased ST. In mid-aged women, changes at work were associated with increased ST, while retiring and decreased income were associated with decreased ST. ConclusionsST changed over nine years in young and mid-aged Australian women. The life events they experienced, particularly events related to work and family, were associated with these changes.

Level of Sedentary Behavior and Its Associated Factors among Saudi Women Working in Office-Based Jobs in Saudi Arabia

“…O’Donoghue et al [25] systematically reviewed 74 studies on correlates of sedentary behavior, yet only 8 studies reported on the presence of children in the household. Five of these studies found lower overall sitting times among people who have children [26,27,28,29,30]; however, two reported higher sitting times while commuting [27,31]. Busschaert et al [32] found that adults with children sat 21% less while using a home computer.…”

Temporal trends in sitting time by domain in a cohort of mid-age Australian men and women

“…Increases in sitting time for transportation and work over the 6-year period were only observed in women. Other self-report research with Australian mid-aged women has found that an increase in overall sitting time was associated with "changes at work", which were discussed as potentially reflecting increasing (sedentary) seniority and managerial responsibilities and subsequently more desk based work [25). Increased occupational sitting time may also reflect more mid-aged women returning to the workforce: Australian workforce data indicate a marked increase in women aged 55-59 in employment during the past decade, from 50% in 2005 to 64% in 2016 [13].…”

Long‐term determinants of changes in television viewing time in adults: Prospective analyses from the Young Finns Study

“…Furthermore, few longitudinal studies have revealed the patterns and predictors of sitting time throughout adulthood, suggesting that several factors and life events (eg, male gender, higher education, full‐time employment, staying obese, and consistently low physical activity levels, and changing jobs, retiring, or illness) contribute to high sitting levels. Divergent associations were identified for different aged groups for women . In all of these studies, both total and prolonged sitting time were limited using subjective classification analysis, and the sample included participants with a wide range of ages.…”

“…Divergent associations were identified for different aged groups for women. 25 In all of these studies, both total and prolonged sitting time were limited using subjective classification analysis, and the sample included participants with a wide range of ages. However, no studies have focused specifically on whether changes in TV-time would be substantially limited by long-term sociodemographic and health factors.…”
