Objective:To systematically evaluate the relationship between sedentary behavior (SB) and the risk of developing gestational diabetes mellitus (GDM).Methods:PubMed, Medline, EMBASE, CINAHL, the Cochrane Library, the Rehabilitation & Sports Medicine Source, the Sedentary Behavior Research Database (SBRD), Wanfang Database, the China Journal full-text database, and the China Biomedical Literature Database were searched for cohort studies, case-control studies, and cross-sectional studies concerning the risk of SB and GDM from the establishment of the database to January 2021. Two researchers screened the literature, extracted data, evaluated the quality of the data according to the inclusion and exclusion criteria, and, finally, produced a descriptive analysis of the results.Results:A total of 11 studies were included, including eight cohort studies, two cross-sectional studies, and one case-control study. The overall quality of the studies was moderate. The prevalence of GDM was 5.04%-26.81%, and the prevalence of SB before and during pregnancy was 39.47%-40.21% and 28.86%-93.50%, respectively. In terms of the prevalence of SB before pregnancy, four moderate-quality studies reported no association with GDM risk. In terms of SB during pregnancy, four moderate-quality studies reported no association with GDM risks, and four studies (one of high quality and three of moderate quality) reported an association with GDM risks, two of which focused on the second trimester. There was considerable heterogeneity between studies on the diagnosis of GDM and SB.Conclusion:SB before pregnancy is not associated with the risk of GDM, while the relationship between SB and the risk of GDM is unclear, but the level of SB in the second trimester of pregnancy may be positively associated with the risk of GDM.

Objective:To conduct a scoping review of health behavior-related assessment tools for pregnant women with gestational diabetes mellitus (GDM).Methods:A total of 6 Chinese and English databases, including CNKI, Wanfang Database, China Biomedical Literature Database, PubMed, Web of Science Core set and Embase, were systematically searched by the terms of “gestational diabetes mellitus”，“health behavior”，“assessment”. The relevant contents of GDM health behavior-related assessment tools were retrieved for systematic analysis, and the results were normalized reported. The search period was from the establishment of the databases to February 1, 2023.Results:A total of 2 657 literatures were retrieved, and 41 literatures were finally included after screening, including 16 literatures on the development and verification of assessment tools, 2 literatures on localization of assessment tools, and 23 literatures on the application of the assessment tools. A comprehensive analysis was conducted on 18 assessment tools, including 16 original assessment tools and 2 localized assessment tools, spanning the years 1987 to 2020. The assessment content covered dietary behavior, physical activity behavior, medication adherence, blood glucose monitoring behavior, treatment adherence, self-management behavior, and health-promoting lifestyles. Among them, 7 assessment tools were validated for reliability and/or validity in pregnant women with GDM. Among the 23 studies that covered the implication of the assessment tools, the Pregnancy Physical Activity Questionnaire and Health-Promoting Lifestyle Ⅱ were the most commonly utilized tools for assessing health behaviors in pregnant women with GDM.Conclusions:There is a wide variety of assessment tools related to health behaviors in pregnant women with GDM, and the assessment content is relatively rich. However, most of the assessment tools have not been validated for their reliability and validity within the GDM population, limiting their clinical application and promotion.

Objective: To integrate the best evidence of venous thromboembolism (VTE) prevention into practice, improve nurses′ compliance, and reduce the incidence of VTE in orthopaedic department. Methods: Guided by the standard procedure in the JBI-Paces program, collected the best evidence from online databases and set the standards. Collected data through field observation, interviews and review of nursing records. A total of 167 patients and 36 nurses we recruited in the study and audited twice. We judged the result by the knowledge level of nurses and patients, nurses′ compliance with the evidence and the incidence rate of VTE. Results: In baseline review, three criteria of poor compliance, "the correct situation of daily inspection of VTE risk assessment", "Wear gradient pressure stockings correctly for VTE high-risk patients", "Intermittent pneumatic compression device (IPCD) used twice a day for 30 minutes each time", were significantly improved after the application of evidence, increased from 47.22% (17/36) ,36.11% (13/36) ,36.11% (13/36) to 86.11% (31/36) , 86.11% (31/36) , 91.67 (33/36) respectively (χ²=12.25, 18.94, 24.08, all P < 0.05); The incidence of VTE decreased from 2.7% to 0 (P=0.195); the correct rate of VTE risk assessment, awareness rate of health education among patients, implementation rate of physical preventive measures and qualified rate of VTE-related knowledge and skills among nurses increased from 82.43% (61/74) ,74.32% (55/74) ,83.78% (62/74) ,77.03% (57/74) to 97.85% (91/93) ,91.40% (85/93) ,97.85% (91/93) ,96.77% (90/93) respectively (χ²= 8.86-15.24, all P < 0.01) . Conclusion The integration of best evidence standardize nurses′ behaviors, reduce the incidence rate of VTE, improve the quality of clinical care and promote the satisfaction of patients continuously.
