Abstract Body:
Purpose The purpose of this study is to evaluate the relationship between age and affective symptoms (fatigue, distress, sadness) and the association with sedentary time in women participating in the Lifestyle Intervention for oVarian Cancer Enhanced Survival [(LIvES)- GOG/NRG 0225]. Methods Self-reported baseline affective symptom severity (N= 499) and interference (N= 165; 0- 10; mean score of symptom interference from all symptoms with mood, relations with other people, and enjoyment of life) were collected using the MD Anderson Symptom Inventory from ovarian cancer survivors participating in the LIVES study. Sedentary time (hours/day) was estimated from and the Arizona Physical Activity Questionnaire (N= 1133). Total symptom severity, affective symptom severity and affective symptom interference were compared between survivors <65 and ≥65 years of age using 2-sided t- tests. Adjusted linear regression models were used to evaluate symptom constructs with sedentary time by age. Results The mean age of ovarian cancer survivors in the study was 59.8 y; 32.9% were ≥65 y. Total symptom severity was significantly lower in survivors ≥65 years of age (mean: 1.15 ± 0.86, p= 0.002) when compared to those <65 years. Affective symptom severity also differed by age (mean: 2.05 ± 1.80, p= 0.02). However, no difference in affective symptom interference by age group was demonstrated (p= 0.09). Total symptom severity and affective symptom interference were not associated with sedentary time overall nor by age group of survivors. However, among survivors <65 years of age, affective symptom severity was associated with higher sedentary time (β= 0.32, 95% CI= 0.06-0.58, p= 0.018); the same was not observed for survivors ≥65 years. Conclusions Key findings from this study include that younger survivors carry a higher total symptom burden and affective symptom burden than older survivors. Age is therefore an important factor when evaluating symptom burden. Additional research is needed to more robustly evaluate the impact of age on symptom burden in ovarian cancer survivors.
