Knowledge of A1c Predicts Diabetes Self-Management and A1c Level among Chinese Patients with Type 2 Diabetes.

ABSTRACT: 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.

Project description:High-fiber diet interventions have been proven to be beneficial for gut microbiota and glycemic control in diabetes patients. However, the effect of a low level of fiber in habitual diets remains unclear. This study aims to examine the associations of habitual dietary fiber intake with gut microbiome profiles among Chinese diabetes patients and identify differential taxa that mediated associations of dietary fiber with HbA1c level. Two cross-sectional studies and one longitudinal study were designed based on two follow-up surveys in a randomized trial conducted during 2015−2017. The study included 356 and 310 participants in the first and second follow-ups, respectively, with 293 participants in common in both surveys. Dietary fiber intake was calculated based on a 3-day 24-h diet recall at each survey and was classified into a lower or a higher group according to the levels taken based on the two surveys using 7.2 g/day as a cut-off value. HbA1c was assayed to assess glycemic status using a cut-off point of 7.0% and 8.0%. Microbiome was profiled by 16S rRNA sequencing. A high habitual dietary fiber intake was associated with a decrease in α-diversity in both the cross-sectional and longitudinal analyses. At the first follow−up, phylum Firmicutes and Fusobacteria were negatively associated with a higher dietary fiber intake (p < 0.05, Q < 0.15); at the second follow-up, genus Adlercreutzia, Prevotella, Ruminococcus, and Desulfovibrio were less abundant in patients taking higher dietary fiber (p < 0.05, Q < 0.15); genus Desulfovibrio and Ruminococcaceae (Unknown), two identified differential taxa by HbA1c level, were negatively associated with dietary fiber intake in both the cross-sectional and longitudinal analyses, and mediated the dietary fiber-HbA1c associations among patients taking dietary fiber ≥ 7.2 g/day (mediation effect β [95%CI]: −0.019 [−0.043, −0.003], p = 0.018 and −0.019 [−0.046, −0.003], p = 0.016). Our results suggest that habitual dietary fiber intake has a beneficial effect on gut microbiota in Chinese diabetes patients. Further studies are needed to confirm our results.

Project description:PurposeDiabetes patients must be equipped with the necessary knowledge to confidently undertake appropriate self-care activities. We prepared a diabetes self-management education (DSME) intervention and assessed how it affected patients' self-reported levels of diabetes knowledge, self-care behaviors, and self-efficacy.Patients and methodsA before-and-after, two-group intervention study was conducted at Jimma University Medical Centre among adult patients with type 2 diabetes. At baseline, we randomly assigned 116 participants to the DSME intervention and 104 to a comparison group. Six interactive DSME sessions supported by an illustrative handbook and fliers, experience-sharing, and take-home activities were administered to the intervention group by two nurses during a six-month period. Diabetes knowledge, self-care behaviors, and self-efficacy were measured at baseline and at nine months following the commencement of DSME intervention (endpoint) in both groups.ResultsAt the endpoint, data from 78 intervention group participants and 64 comparison group participants were included in final analysis. The difference in the mean Diabetes Knowledge Scale scores before and after the DSME intervention was significantly greater in the intervention group (p = 0.044). The measured self-care behaviors included diet, exercise, glucose self-monitoring, footcare, smoking, alcohol consumption, and khat chewing. The mean number of days per week on which the intervention group participants followed general dietary recommendations increased significantly at the endpoint (p = 0.027). The intervention group followed specific dietary recommendations (p = 0.019) and performed footcare (p = 0.009) for a significantly greater number of days. There were no significant differences within or between the groups in other self-reported diabetes self-care behavior regimens or in diabetes self-efficacy.ConclusionOur study found significant improvements in the intervention participants' diabetes knowledge scores and in their adherence to dietary and footcare recommendations. This demonstrates that our DSME intervention may be of clinical importance in developing countries such as Ethiopia.Trial registrationClinicalTrials.gov, Identifier NCT03185689, retrospectively registered on June 14, 2017: https://clinicaltrials.gov/ct2/show/NCT03185689.
