Abstract
In Australia, a part of Duncombe et al. (2007) and Sui et al. (2013) no previous studies have collected longitudinal data on the prevalence of physical activity among pregnant women. Moreover, most studies have had excluded household, transport, and occupational activities and some had insufficient number of participants, which can affect the investigation of physical activity (Cheung et al., 2007; Duncombe et al., 2007a; Wilkinson et al., 2009). The aim of this investigation was to assess work activities among Australian pregnant women. A total of 200 healthy pregnant women were recruited from the Royal Hospital for Women at Randwick and Wollongong Hospital, NSW to participate in this study. Descriptive statistics were conducted for both type of activity across study stages using SPSS Ver 21. Results showed a significant (p < 0.05, at 0.000) decrease in weekly occupational energy expenditure (MET-h.wk-1 ) during postpartum (1.8 ±3.7 MET-h.wk-1 ) compared to pre-pregnancy (22.9 ±19.8 MET-h.wk-1 ) and during pregnancy (16.2 ±13.3 MET-h.wk-1 ).
