Intensity- and domain-specific physical activity levels between cancer survivors and non-cancer diagnosis individuals: a propensity score matching analysis.

To examine intensity- and domain-specific physical activity (PA) levels between Korean cancer survivors compared with non-cancer individuals. We used data from the 2014–2016 Korean National Health and Nutrition Examination Survey (KNHNES) to compare PA levels between 639 cancer survivors and 15,352 non-cancer individuals. Using the 1:5 propensity score matching analysis by sex, age, body mass index (BMI), and education level, 3195 non-cancer individuals were selected. Global Physical Activity Questionnaire (GPAQ) was used to assess PA levels. Cancer survivors were more likely to participate in a leisure-time PA (64.5 ± 157.9 vs. 51.8 ± 145.3 min/week, p < 0.002) compared with non-cancer individuals, while no difference was observed between groups in work and transportation. Cancer survivors undergoing treatment participated in more leisure-time PA (80.9 ± 169.2 vs. 56.6 ± 151.8 min/week, p < 0.02) compared with cancer survivors who completed cancer treatment. However, we found no significant difference in vigorous-intensity PA (18.8 ± 113.9 vs. 20.5 ± 156.1 min/week, p = 0.56) and moderate-intensity PA (186.2 ± 313.1 vs. 203.1 ± 355.3 min/week, p = 0.17) levels between cancer survivors and non-cancer individuals. This study showed that cancer survivors were more participated in leisure-time PA compared with age, gender, BMI, and education levels matched non-cancer individuals.
