Short-Term Outcomes and Multidimensional Factors Associated With Preoperative Sedentary Behavior Among Chinese Older Adults With Gastric Cancer: An Observational Study.

Purpose: The current study aimed to examine the short-term outcomes and multidimensional factors associated with preoperative sedentary behavior among Chinese older adults with gastric cancer.

Method: An observational study was conducted among older adults with gastric cancer in a tertiary hospital in Jiangsu, China. A total of 393 participants were enrolled by convenience sampling. Sedentary behavior was assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). Logistic regression was applied to explore the relationship between preoperative sedentary behavior and short-term outcomes. Univariate and multivariate analyses were used to determine the factors associated with participants' sedentary behavior.

Results: Preoperative sedentary behavior was related to multiple outcomes, including total complications, prolonged length of stay, and increased hospitalization costs. Two or more comorbidities and depression were risk factors for sedentary behavior. High-density lipoprotein; female sex; and high school, middle school, and primary school and below educational levels were protective factors for sedentary behavior.

Conclusion: Health care professionals need to simultaneously concentrate on multidimensional aspects linked to sedentary behavior to successfully administer behavioral interventions for enhancing older adults' overall prognosis. [Journal of Gerontological Nursing, xx(x), xx-xx.].
