Analysis of Influencing Factors of Preoperative Frailty in Elderly Patients With Gastric Cancer Based on the Health Ecology Theory

Study Overview
=================
Brief Summary
-----------------
Frailty is common in patients with gastric cancer undergoing surgical treatment. Preoperative frailty can lead to many adverse outcomes in patients after surgery. This study aims to comprehensively and systematically analyze the influencing factors of preoperative frailty in patients with gastric cancer based on the health ecology theory , to change some critical variable factors in the future, improving the overall prognosis of patients.

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Frailty assessed by Frailty Phenotype (FP) | The total score is 0 5, and a score of 0 3 is considered as frailty. | preoperative period | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Nutrition assessed by Nutrition Risk Screening 2002 (NRS2002) | NRS2002 comprises 3 components: nutritional status, disease status and age, with a total score ranging from 0 to 7. A score of ≥3 is considered to be at nutritional risk. | preoperative period | 
| Anxiety and depression assessed by Hospital Anxiety Depression Scale (HADS) | HADS contains 2 subscales: anxiety and depression subscales. Each subscale consists of 7 items, with a total score ranging from 0 to 21. A score of each subacale reaches 8 or more is regarded as the presence of anxiety or depression. | preoperative period | 
| Social support assessed by Social Support Rate Scale (SSRS) | SSRS contains 10 items and 3 dimensions, which are objective support, subjective support, and support utilization, with higher scores indicating higher degrees of the corresponding dimensions. | preoperative period | 
| Familial caring degree assessed by Family Concern Index Questionnaire (APGAR) | The total score ranges from 0 to 10, and a score of ≤6 is considered as having family dysfunction. | preoperative period | 
| Sleep assessed by Pittsburgh Sleep Quality Index (PSQI) | A total score range from 0 to 21, a score of 0 5 indicates very good sleep quality; a score of 6 10 indicates good sleep quality; a score of 11 15 indicates poor sleep quality; a score of 16 21 indicates very poor sleep quality. | preoperative period |
