Diabetes-related distress is one of the psychological disorders affecting patients with diabetes, yet there are few studies about diabetes-related distress in Chinese patients. To assess the level of psychological distress and examine its associated factors, we conducted a cross-sectional analysis of patients with type 2 diabetes mellitus from a Chinese tertiary hospital. The Diabetes Distress Scale (DDS) and the General Self-Efficacy Scale (GSES) were administered. There were 210 (57.85%) patients with little or no diabetes-related distress, 84 (23.14%) with moderate diabetes-related distress and 69 (19.01%) with high diabetes-related distress. Stepwise multiple linear regression showed that sleep time was significantly related to the DDS total score and the subscale scores of emotional burden (EB) (β=-0.190, -0.379), respectively. GSES was associated with the DDS total score (β=-0.128) and the EB score (β=-0.153). Oral medication plus insulin was significantly related to regimen-related distress (RD) (β=0.137), physician-related distress (PD) (β=0.152) and interpersonal distress (ID) (β=0.103). Physical activity (β=-0.185) and making meal plan with health care professionals(HCP) (β=-0.169) were associated with RD. The prevalence of diabetes-related distress among patients with type 2 diabetes mellitus was high in China. DDS and EB were associated with poorer sleep time and lower self-efficacy. Interventions to improve sleep are needed. Qualitative and longitudinal studies are required to understand why type 2 diabetic patients are not getting enough sleep.

KnowledgeSelf-care a b s t r a c t Purpose: To investigate the knowledge and behaviours on foot self-care in patients with type 2 diabetes mellitus; analyse the influential factors, and provide information for the intervention study.Methods: A total of 5961 patients with type 2 diabetes mellitus from 144 hospitals in China were included in the study. The investigation content included patients' demographic data, foot self-care knowledge and behaviours. The investigation tools were the questionnaires on the general diabetes information, on the foot self-care knowledge, and on the foot selfcare behaviours.Results: The foot self-care knowledge was medium and the foot self-care behaviour was poor. The status of knowledge and behaviours were influenced by education, duration of diabetes mellitus, periodic inspection, and education about diabetic complications. Pearson analysis demonstrated that there was positive correlation between knowledge score and behaviour score (r ¼ 0.27, p < 0.001).Conclusions: The status of foot self-care knowledge and behaviours are not optimistic. According to the patients' own characteristics, the theory of knowledge, attitude and practice applies to encouraging patients to go for periodic inspection and education about diabetic complications so as to enhance the knowledge and promote the self-care behaviours.

The insulin injection skill of patients with diabetes in mainland China was poor, and the incidence of lipohypertrophy, bleeding, and needle reuse was high. Frequency of daily insulin injection and needle reuse may relate to the incidence of lipohypertrophy and bleeding. The bleeding and bruising at the injection sites may be associated with suboptimal absorption of injected insulin. Improved education in optimal insulin injection technique, including reducing needle reuse and correct rotation of injection sites should be emphasized.

Aim: The purpose of this study is to explore the long-term effects of aerobic training (AT), resistance training (RT), and combined training (AT + RT) on the prevention of T2D incidence in patients with prediabetes. Materials and methods:In this randomised controlled trial, people with prediabetes (fasting glucose ≥5.6 and <7.0 mmol/L and/or 2-h glucose ≥7.8 and <11.1 mmol/L on the 75-g oral glucose tolerance test and/or haemoglobin A 1c ≥5.7% and <6.4%) were randomly assigned to the control group, AT group, RT group, or AT + RT group.Supervised exercise programmes, including AT, RT, and AT + RT, were completed for 60 minutes per day, three non-consecutive days per week for 24 months. The primary outcome was the incidence of T2D; secondary outcomes were blood glucose and lipid levels, including total cholesterol (TC) and standard 2-hour oral glucose tolerance (2hPG).Results: A total of 137 (80%) subjects with a mean age of 59 years (45 men, 92 women) entered the final analysis. After 24 months of intervention, the incidences of T2D adjusted by sex and age were significantly decreased by 74% (95% CI, 38-89), 65% (95% CI, 21-85), and 72% (95% CI, 36-87) in the AT + RT, RT, and AT groups compared with the control group (HR: AT + RT 0.26 [95% CI, 0.11-0.62], RT 0.35 [95% CI, 0.15-0.79], and AT 0.28 [95% CI, 0.13-0.64]). The cumulative T2D incidences were significantly lower in the AT + RT, RT, and AT groups than in the control

Our study indicated that perceived diabetes empowerment is a predictor of self-care behavior and HbA1c in Chinese patients with type 2 diabetes. Therefore, interventions to enhance and promote patient empowerment should be essential components of diabetes education programs to improve self-care behavior and glycemic control.

This study was to identify current A1c understanding status among Chinese patients with type 2 diabetes, assess if knowledge of A1c affects their diabetes self-management and their glycemic control and recognize the factors influencing knowledge of A1c among patients with type 2 diabetes. A multi-center, cross-sectional survey was conducted between April and July 2010 in 50 medical centers in the Mainland China. Participants were recruited from inpatients and outpatients who were admitted to or visited those medical centers. The survey included core questions about their demographic characteristics, diabetes self-management behavior, and A1c knowledge. Overall, of 5957 patients, the percentage of patients with good understanding was 25.3%. In the multivariable logistic regression model, the variables related to the knowledge of A1c status are presented. We discovered that patients with longer diabetes duration (OR = 1.05; 95%CI = 1.04–1.06) and having received diabetes education (OR = 1.80; 95%CI = 1.49–2.17) were overrepresented in the good understanding of A1c group. In addition, compared to no education level, higher education level was statistically associated with good understanding of A1c (P<0.001). The percentage of patients with good understanding varied from region to region (P<0.001), with Eastern being highest (OR = 1.54; 95%CI = 1.32–1.80), followed by Central (OR = 1.25; 95%CI = 1.02–1.53), when referring to Western. Only a minority of patients with type 2 diabetes in China understood their A1c value. The patients who had a good understanding of their A1c demonstrated significantly better diabetes self-management behavior and had lower A1c levels than those who did not.
