Social support and self-management behaviour among patients with Type 2 diabetes.

AIMS: To investigate the relationship between structural and functional social support and patient activation, diabetes-related emotional distress, perceived diabetes care, self-management behaviour and HbA(1c) levels among patients with Type 2 diabetes. METHODS: Self-administered questionnaires were collected from 2572 patients with Type 2 diabetes. After adjusting for gender, age and education, Tobit and logistic regression models were used to examine associations between social network and patient activation, psychosocial problems, self-management behaviours and HbA(1c) levels. RESULTS: Frequent contact with friends was associated with more positive scores for activation, fewer psychosocial problems, more positive assessment of care and health-promoting self-management behaviours such as frequent exercising and frequent foot examinations. Frequent contact with family was associated with more positive assessments of care. Living with a partner was associated with lower prevalence of smoking, a higher frequency of foot examinations and higher HbA(1c) levels. A poor functional social network, measured as perceived lack of help in the event of severe illness, was associated with low patient activation, greater emotional distress, negative assessment of care, less health-promoting eating habits and less frequent foot examinations. CONCLUSIONS: Good social support is significantly associated with health-promoting behaviours and well-being among patients with Type 2 diabetes. However, HbA(1c) levels are higher for cohabitant persons, indicating barriers for social support. Intervention research is needed to investigate the causal relationship between social networks and health-promoting behaviours. This knowledge should be used in clinical practice when targeting and designing education, support and care for patients with Type 2 diabetes.

Patient factors and glycaemic control--associations and explanatory power.

AIMS: To investigate the association between glycaemic control and patient socio-demographics, activation level, diabetes-related distress, assessment of care, knowledge of target HbA(1c), and self-management behaviours, and to determine to what extent these factors explain the variance in HbA(1c) in a large Danish population of patients with Type 2 diabetes. METHODS: Cross-sectional survey and record review of 2045 patients from a specialist diabetes clinic. Validated scales measured patient activation, self-management behaviours, diabetes-related emotional distress, and perceived care. The electronic patient record provided information about HbA(1c), medication, body mass index, and duration of diabetes. Data were analysed using multiple linear regression models with stepwise addition of covariates. RESULTS: The response rate was 54% (n = 1081). Good glycaemic control was significantly associated with older age, higher education, higher patient activation, lower diabetes-related emotional distress, better diet and exercise behaviours, lower body mass index, shorter duration of disease and knowledge of HbA(1c) targets (P < 0.05 for all). Patient socio-demographics, behaviour; perceptions of care and diabetes distress accounted for 14% of the total variance in HbA(1c) levels (P = 0.0134), but the variance explained was higher for respondents treated with medications other than insulin. CONCLUSIONS: Our study emphasizes the complex relationships between patient activation, distress and behaviour, specific treatment modalities and glycaemic control. Knowledge of treatment goals, achieving patient activation in coping with diabetes, and lowering disease-related emotional stress are important patient education goals. However, the large unexplained component of HbA(1c) variance highlights the need for more research to understand the mechanisms of glycaemic control.
