Lacombe J, et al. – This study's aims were to describe sedentary behavior (SED) behaviors among breast cancer survivors (BCS) and identify unique SED groups based on different SED dimensions as well as identify personal and cancer–specific factors that discriminate SED clusters and examine the relationship between SED clusters and depression symptoms. This investigation highlighted the importance of understanding multiple dimensions of SED among BCS. The findings suggested that decreasing SED during the early survivorship period might alleviate depression symptoms.

Methods

• For this purpose, baseline self-report demographic and medical information was gathered from one hundred eighty-seven BCS.
• SED and physical activity were evaluated more than seven days utilizing an accelerometer.
• Self-reported depression symptoms were reported 3 months later.
• Multiple dimensions of SED were identified and analyzed in cluster analysis.
• Using multivariate analysis of variance and chi-square analyses, the clusters were examined for differences.
• Using an analysis of covariance, the difference in depression symptoms among SED groups was assessed.

Results

• According to the findings obtained, high and low SED groups were identified.
• The findings from the present study suggested that survivors in the high SED cluster were significantly older, heavier, less physically active, reported less education, and were more likely to have undergone lymph/axial node dissection.
• It was found that women in the high SED cluster reported significantly higher depression symptoms prospectively (M = 9.50, SD = 6.07) compared to women in the low SED group (M = 6.89, SD= 5.18), F(8,179) = 4.97, p = 0.03, R2 = 0.34.
