Sedentary behaviour of pregnant women in South Africa: A cross-sectional study

Abstract

Background: Sedentary behaviour is a growing global public health concern that affects not only the general population but also pregnant women. Inactivity during pregnancy could have implications for the development of cardio-metabolic complications such as prenatal obesity, gestational diabetes mellitus, and hypertension, as well as mental well-being. Encouraging light prenatal physical exercise is crucial in improving maternal health of mothers as well as the baby. However, information on the sedentary behaviour of pregnant women in South Africa is limited, particularly in the Eastern Cape region. Therefore, this study investigates the proportion of time pregnant women spend in sedentary behaviours in the context of the Eastern Cape in South Africa.

Methods: In this cross-sectional study, the sedentary time of 1082 pregnant women attending public health facilities in Buffalo City Municipality, Eastern Cape, South Africa, was assessed using the Pregnancy Physical Activity Questionnaire. Descriptive statistics were used to analyse the sedentary time of the participants.

Results: The participants’ mean age was 27.0 years, and the standard deviation was 6.2 years. The pregnant women spent more than 3 h per day sitting (40.0%). Furthermore, a significant proportion spent 4 h to more than 6 h per day watching television or videos (46.2%) and sitting, reading, or making phone calls (51.6%) during their off-work physical activity.

Conclusion: The majority of pregnant women exhibit high levels of sedentary behaviour.

Contribution: Measures to encourage active physical activity during pregnancy are crucial in preventing a sedentary lifestyle among pregnant women.
