The Effect of Social Support on Glycemic Control in Patients with Type 2 Diabetes Mellitus: The Mediating Roles of Self-Efficacy and Adherence.

Ample evidence suggests that social support, self-efficacy, and adherence significantly, independently, and together affect glycemic control in patients with type 2 diabetes mellitus (T2DM), but the pathway from social support to glycemic control remains unclear. This study hypothesized that the effect of social support on glycemic control was mediated sequentially by self-efficacy and adherence. Patients with T2DM were recruited from two hospitals in Guangzhou, China, from January 1 to July 31, 2014, and their sociodemographic clinical data and their assessments on social support, self-efficacy, and adherence were obtained from medical records and self-completed questionnaires.

Type D personality as a predictor of self-efficacy and social support in patients with type 2 diabetes mellitus.

Objective: The aim of this study was to estimate the prevalence of Type D personality and assess the relationship between this personality type and self-efficacy/social support in Chinese patients with type 2 diabetes mellitus (T2DM).

Patients And Methods: From January 1, 2014, to July 31, 2014, 532 consecutive patients with T2DM were recruited from two hospitals in Guangzhou, China. The participants completed questionnaires containing questions about sociodemographic characteristics, Type D personality, self-efficacy, and social support scales, and their medical records were reviewed for additional data.

[Matrix metalloproteinase-3 genotype distribution and its relation with blood pressure profiles in Guangzhou rural population].

Objective: To analyze the distribution of matrix metalloproteinase-3 (MMP-3) genotype and its association with the blood pressure profiles in Guangzhou rural population.

Methods: This study was conducted among 680 rural residents aged 40-70 years (including 314 men and 366 women) from 3 villages in an rural area of Guangzhou. The blood pressures of the subjects were measured and blood samples were collected for genotype analysis using polymerase chain reaction and direct sequencing of the MMP-3 gene promoter region to detect the 5 adenines (5A)/6 adenines (6A) polymorphisms.
