Physical Activity Measured by Accelerometry in Mozambican Older Adult Women Attending a Regular Exercise Program

摘要

Time spent in different Physical Activity (PA) Intensities of 72 Mozambican older adult women (67 +/- 7 years old) was assessed by means of triaxial accelerometers for 7 consecutive days, and participants were stratified based on their body mass index, as being normal weight (NW, n = 23); overweight (n = 16); or obese (OB, n = 33). Overall, most daily time was spent in sedentary activities (614 +/- 111 min or 69.1%) and light PA (181 +/- 56 min or 20.2%). On average, moderate to vigorous PA (MVPA) was performed during 10.6% of the day (93 +/- 44 min). Time spent in MVPA was significantly higher in the NW compared to OB category (112.8 +/- 51.5 vs. 81.0 +/- 36.3; p = .021). The overweight group did not differ in time spent in MVPA when compared to NW and OB group. Overall, 75% of the participants spent more than 60 min a day in MVPA (NW: 83%; overweight: 81%; OB: 67%). Pearson's correlation between body mass index and total MVPA controlling for age was -.39 (p < .001). It was concluded that Mozambican older adult women living in urban and rural areas of Maputo province engaged in relatively high Physical Activity Intensities compared with individuals of similar ages in high-income countries, regardless of their nutritional status.
