Abstract
Adequate nutrition in a hospital setting is essential for achieving optimal health outcomes in oncology patients. This study specifically investigated the interrelationships between nutritional status, daily habits, and hospital length of stay (LOS) in ovarian cancer patients undergoing chemotherapy. A prospective longitudinal study was conducted from August 2019 to January 2022 in a tertiary hospital. Throughout the study, nutritional status, biochemical indicators, diet, and physical activity were meticulously recorded at different stages of chemotherapy: before chemotherapy (T(0)), the first course (T(1)), third course (T(2)), and fifth course (T(3)). To determine the factors influencing LOS, a generalized estimation equation (GEE) was employed. A total of 460 patients completed the follow-up period. The findings revealed a decline in nutritional risk among patients by 9.90% at T(1), 17.62% at T(2) and 18.26% at T(3) (χ(2) = 79.220, P < 0.001). The proportion of people receiving enteral nutrition showed an upward trend (χ(2) = 15.202, P < 0.001). Notably, the proportion of patients adhering to a healthier diet increased by 40.44% by the study's conclusion, while the number of patients abstaining from physical activity or engaging in solely low-intensity activities decreased by 21.08%. Moreover, as the chemotherapy cycle progressed, daily activity steps exhibited an upward trajectory (F = 5.986, P < 0.001), while the LOS experienced a significant reduction (F = 21.298, P < 0.001). This study identified hypoproteinemia (protein level < 34 g/L), a high nutritional risk (NRS 2002 score ≥ 3), a short duration of sleep (≤ 7 h/day), and a lower daily activity level as risk factors for LOS. Receiving enteral nutrition support is a protective factor for LOS. Significant improvements in nutritional status, diet, and physical activity have been observed among ovarian cancer patients during their chemotherapy cycles. Reduced nutritional risks, implementation of nutritional support, good physical activity, and adequate sleep were associated with a shorter LOS.
