Objective:To investigate the relationship between self-management ability and self-efficacy in coronary heart disease (CHD) patients, and the influential factors.Methods:From April to June 2016, a questionnaire survey was conducted among 236 patients with coronary heart disease selected by simple random sampling method in the outpatient clinic of Pengpu Community Health Service Center; and the Coronary Artery Disease Self-management Scale and self-efficacy questionnaire were used in the survey. The correlation between scores of the two scales was analyzed; the scores were compared between patients with percutaneous coronary intervention (PCI) and those without PCI, between patients with myocardial infarction (MI) and those without MI. Multiple linear regression was performed to elucidate the influencing factors of self-management ability and self-efficacy of CHD patients.Results:The mean scores of self-management ability and self-efficacy were (75.5±15.5) and (24.8±10.8), respectively. The self-management ability was significantly correlated with self-efficacy in CHD patients(r=0.398-0.683, P<0.05). The self-management score of patients with PCI was higher than those without PCI[ (80.4±14.9) vs.(72.5±15.1), t=3.38, P<0.01]. The scores of self-management[(85.0±16.4) vs.(72.9±14.2), t=5.14, P<0.01]and self-efficacy[(29.3±12.0) vs. (23.6±10.2), t=3.39, P<0.01] of patients with MI were higher than those without MI. Multiple linear stepwise regression analysis indicated that age over 65, history of MI, history of PCI, history of smoking and self-efficacy score were all factors influencing self-management behavior in patients with CHD ( R=0.735; R2=0.540; F=26.451, P<0.01). Smoking history and self-management score were the influencing factors of self-efficacy in patients with CHD ( R=0.690; R2=0.476; F=20.425, P<0.01). Conclusion:The self-efficacy of patients with CHD is closely related to their self-management behavior, so we should strengthen their self-efficacy and improve their self-management level by comprehensive measures, particularly for patients without PCI.

Objective To investigate the prevalence of gestational diabetes mellitus (GDM) among pregnant women in Wuhan, and to explore the application value of oral glucose tolerance test (OGTT) results in the screening, diagnosis and treatment of GDM. Methods A retrospective analysis was carried out on the OGTT results of 26 558 pregnant women from Hubei Maternal and Child Health Hospital from January 2018 to December 2018. Results (1) A total of 1 754 cases were diagnosed with GDM, with a positive rate of 6.60%. Among them of 776 had fasting blood glucose ≥5.1mmol/L, 880 had 1-hour blood glucose ≥10.0mmol/L, and 798 had 2-hour blood glucose ≥8.5mmol/L. (2) The positive rates of fasting blood glucose, 1-hour blood glucose, and 2-hour blood glucose in the ≥35-year-old age group were all over two times higher than those in the <35-year-old age group (all P<0.01). (3) The ratio of people with single-point positive, two-point positive and three-point positive was 7:2:1. (4) FBG, 1-hour blood glucose and 2-hour blood glucose concentrations were all positively correlated with each other (all P＜0.01). Among these, the positive correlation between 1-hour blood glucose and 2-hour blood glucose was the most significant (r=0.618, P＜0.01). Conclusions The incidence rate of GDM among pregnant women in Wuhan reached 6.60%, and the prevalence in pregnant women over 35 years old was significantly higher. Blood glucose level during pregnancy should be monitored for early detection and intervention to prevent the development of GDM. The relationship between blood glucose concentrations at different time points in the OGTT test had reference value for clinical diagnosis and treatment.
