Body size and physical activity levels of adults on Rarotonga, the Cook Islands
2001
Ulijaszek, Stanley J.
Few studies of physical activity and energy expenditure have been carried out in the Pacific Region. In this study, the physical activity levels (PALs) of adult Cook Islanders living a largely modernised lifestyle by age group and occupation category were determined by a 3 day activity recall diary method. The period of observation included the previous Sunday, as a representative non-working day. A volunteer sample of 332 Cook Islanders aged 22 to 86 years was obtained from the total adult population of Rarotonga. Older adults are significantly less active than younger adults during the working week, but not during the weekend. Males are more physically active than females during the working week, but not on weekends. The mean weekday PAL of males engaged in traditional subsistence or who are unemployed is 1.88, while the mean weekday PAL of females engaged in traditional subsistence or who are housewives is 1.69. Male manual workers have a weekday PAL of 1.96, while female manual workers have a weekday PAL of 1.67. The weekday PAL values for those employed in clerical and administrative work are 1.82 (males) and 1.64 (females), while values for professionals are 1.76 (males) and 1.65 (females). Weekday physical activity is negatively associated with age, in nonlinear fashion. The PALs of adult Cook Islanders living a largely modernised lifestyle is lower in older age groups but does not vary by occupation category.
