Several studies have reported an association between prolonged sedentary behavior and increased breast cancer prevalence in the general female population. However, evidence on this relationship in high-risk groups, such as obese women, is limited. To address this gap, a study examined the association between daily sitting time, physical activity, and breast cancer prevalence in 9,706 obese women, with a median age of 50.28 years.
The study found that obese women with longer daily sitting time had a higher prevalence of breast cancer (2.8%) compared to those with shorter sitting durations, with odds ratios of 1.61, 1.86, and 2.21 for sitting 4–6, 6–8, and over 8 hours per day, respectively, compared to those sitting less than 4 hours.
