- Description
- Introduction: Breast cancer is currently the most commonly diagnosed cancer in South African women. Physical activity has proven to have preventative, treatment and management benefits for breast cancer and other cancers and exercise has been found as both viable and safe during cancer treatment and recovery. However, there is limited research on breast cancer and the levels and preferences of physical activity and sedentary behaviour in a South African context. Therefore, the purpose of this study was to identify levels of physical activity and sedentary behaviour of South African breast cancer survivors and to investigate the physical activity advice and participation preferences of these participants. Methods: A cross-sectional research design was implemented to identify the physical activity, sedentary behaviour levels and exercise preferences of 48 South African breast cancer survivors (age range 45 years). An online survey comprising demographic and anthropometric questions, the Godin leisure-time activity questionnaire (GLTPAQ), the International Physical Activity Questionnaire (IPAQ) and an exercise preference questionnaire was presented to participating breast cancer survivors in order to i) identify the levels of physical activity and sedentary behaviour engaged in, ii) obtain demographic and anthropometric information and iii) identify exercise preferences. A linear mixed model regression was used to examine potential associations between demographic and anthropometric variables and physical activity levels. Chi-squared and Pearson’s Product-Moment correlation tests were used to identify relationships between categorical and numerical variables. A correlation matrix was generated to further explore any correlations. Statistical significance for all measures was set at p<0.05. Results: The mean age of the group was 49 ± 9.87 years. The most common time since diagnosis was <5 years ago and the most common stage of breast cancer was stage I. The mean BMI was 27.87 ± 5.53kg/m2. The most common treatment combination was surgery with either chemotherapy or radiation. According to the leisure score index (LSI) the majority of the group (56%) was active and according to IPAQ data 60% were meeting physical activity guidelines. The highest physical activity levels were seen in the average weekly minutes of moderate-intensity activity, and there was a strong, non-significant positive correlation (p>0.05, R2 = 0.95) between moderate-intensity physical activity and total physical activity levels. High levels of weekly sedentary behaviour and sitting time (302.60 ± 169.96 minutes) were reported. A weak, non-significant, positive correlation was found between total sedentary time and BMI (p>0.05, R2 = 0.1). A weak, non-significant, negative correlation was found between age and sedentary time (p>0.05, R2 = 0.002). More participants below 50 years were insufficiently active compared to above the age of 50 years. 1.7 to 2.6 years since diagnosis saw the greatest number of insufficiently active survivors and the category over 2.6 years since diagnosis saw the most active survivors. Most breast cancer survivors (71.10% & 82.05%) indicated being interested in and feeling capable of participating in an exercise programme (p>0.05, R2 = 0.72). The favoured preference for receiving physical activity advice was face-to-face with an exercise specialist at a cancer centre before treatment. Participation preferences included starting a programme immediately after treatment, in a home-based setting with one or two other people, where walking and a moderate exercise intensity were the preferred exercise type and level of intensity. Data collection occurred both immediately prior to (42% of participants) and during (56% of participants) the South African Covid-19 lockdown, so the results should be seen in light of this context. Conclusion: The current study is one of the first to explore physical activity rates and preferences of South African breast cancer survivors. As a group and individually these survivors were meeting public physical activity guidelines and engaging in the recommended weekly minutes. The high sitting time coupled with the high overweight and obesity levels highlight the need for positive behavioural changes including improved levels of physical activity and reduced sedentary behaviour. These changes need involvement from the numerous levels of society that affect health. Broad physical activity guidelines need to be developed not only to improve physical activity levels in breast cancer survivors but to work as a preventative measure by facilitating physical activity promotion in the general population. The findings of this study demonstrate that this group of South African breast cancer survivors is open to physical activity advice, to programmes and to improving physical activity levels.
