Diabetic control in children and adolescents: Psychosocial factors and therapeutic efficacy

Impact of chronic emotions and psychosocial stress on glycemic control in patients with type 1 diabetes. Heterogeneity of glycemic responses, biological mechanisms, and personalized medical treatment

Many studies have clearly established that chronic psychosocial stress may sustainably worsen glycemic control in patients with type 1 diabetes mellitus (T1DMM), thus promoting diabetes complications. Chronic psychosocial stress may be due to: i) the long-term accumulation of stressful life events that require readjustment on the part of the individual (loosing friends, changing schools), and/or ii) exposure to severe chronic stressors (persistent difficulties and adversities of life). Whatever the reason, many studies have clearly established a positive correlation between chronic psychosocial stress and HbA1c levels. However, a small fraction of patients is minimally affected or not affected at all by chronic psychosocial stress. Conversely, positive life events can substantially improve glycemic control. Recent evidence suggests the existence of subpopulations that differ in personality traits, neurohormonal regulatory responses, and food intake behavior (increased or decreased). Better characterization of the clinical and neurohormonal differences between these subpopulations may help develop personalized treatment strategies in the future. In the near future, psychotherapeutic support and automated insulin delivery (AID) could alleviate chronic stress, prevent worsening glycemic control, and ease the burden of diabetes.

Is the relationship between adherence behaviours and glycaemic control bi-directional at adolescence? A longitudinal cohort study

AIM

To analyse the change in adherence to diabetes treatment and its association with metabolic control from childhood to adolescence. The Tanner pubertal staging model was selected as a marker of developmental maturity.

METHODS

In a multicentre, longitudinal cohort study, 142 children with Type 1 diabetes completed a scale that assessed adherence to treatment and a test of diabetes knowledge at the beginning of the study (T0) and four years later (T4). HbA1c and clinical data were collected at T0 and at T4.

RESULTS

From T0 to T4, the mean HbA1c increased from 8.2 +/- 1.6 to 9.1 +/- 1.4% (P < 0.001). Among patients at pubertal stages 1-4, adherence did not decline from T0 to T4, whereas the HbA1c level increased and a positive correlation between adherence and the knowledge score was noted (r = 0.32; P < 0.02). Among adolescents at pubertal stage 5, the level of adherence decreased (P < 0.01) from T0 to T4 and the HbA1c level increased despite an increase in the knowledge score (P < 0.001), a negative correlation between HbA1c and adherence was found (r = -0.37; P = 0.001) and adherence at T4 significantly added to the prediction of HbA1c at T4.

CONCLUSIONS

In this longitudinal study, an initial worsening of glycaemic control as a result of puberty preceded worsening of adherence behaviours. Low levels of adherence become predictive of HbA1c degradation among pubertal stage 5 adolescents. These results suggest a potential bi-directional relationship between glycaemic control and adherence.

Educational and psychosocial programmes for adolescents with diabetes: approaches, outcomes and cost-effectiveness

Diabetes incurs heavy personal and health system costs. Self-management is required if complications are to be avoided. Adolescents face particular challenges as they learn to take responsibility for their diabetes. A systematic review of educational and psychosocial programmes for adolescents with diabetes was undertaken. This aimed to: identify and categorise the types of programmes that have been evaluated; assess the cost-effectiveness of interventions; identify areas where further research is required. Sixty-two papers were identified and subjected to a narrative review. Generic programmes focus on knowledge/skills, psychosocial issues, and behaviour/self-management. They result in modest improvements across a range of outcomes but improvements are often not sustained, suggesting a need for continuous support, possibly integrated into normal care. In-hospital education at diagnosis confers few advantages over home treatment. The greatest returns may be obtained by targeting poorly controlled individuals. Few studies addressed resourcing issues and robust cost-effectiveness appraisals are required to identify interventions that generate the greatest returns on expenditure.

Specialist nurses in diabetes mellitus

BACKGROUND

The patient with diabetes has many different learning needs relating to diet, monitoring, and treatments. In many health care systems specialist nurses provide much of these needs, usually aiming to empower patients to self-manage their diabetes. The present review aims to assess the effects of the involvement of specialist nurse care on outcomes for people with diabetes, compared to usual care in hospital clinics or primary care with no input from specialist nurses.

OBJECTIVES

To assess the effects of diabetes specialist nurses / nurse case manager in diabetes on the metabolic control of patients with type 1 and type 2 diabetes mellitus.

SEARCH STRATEGY

We carried out a comprehensive search of databases including the Cochrane Library, MEDLINE and EMBASE to identify trials. Bibliographies of relevant papers were searched, and hand searching of relevant publications was undertaken to identify additional trials (Date of last search November 2002).

SELECTION CRITERIA

Randomised controlled trials and controlled clinical trials of the effects of a specialist nurse practitioner on short and long term diabetic outcomes were included in the review.

DATA COLLECTION AND ANALYSIS

Three investigators performed data extraction and quality scoring independently; any discrepancies were resolved by consensus.

MAIN RESULTS

Six trials including 1382 participants followed for six to 12 months were included. Two trials were in adolescents. Due to substantial heterogeneity between trials a meta-analysis was not performed. Glycated haemoglobin (HbA1c) in the intervention groups was not found to be significantly different from the control groups over a 12 month follow up period. One study demonstrated a significant reduction in HbA1c in the presence of the diabetes specialist nurse/nurse case manager at 6 months. Significant differences in episodes of hypoglycaemia and hyperglycaemia between intervention and control groups were found in one trial. Where reported, emergency admissions and quality of life were not found to be significantly different between groups. No information was found regarding BMI, mortality, long term diabetic complications, adverse effects, or costs.

REVIEWER'S CONCLUSIONS

The presence of a diabetes specialist nurse / nurse case manager may improve patients' diabetic control over short time periods, but from currently available trials the effects over longer periods of time are not evident. There were no significant differences overall in hypoglycaemic episodes, hyperglycaemic incidents, or hospital admissions. Quality of life was not shown to be affected by input from a diabetes specialist nurse/nurse case manager.

Teaching assertive communication skills to adolescents with diabetes: evaluation of a camp curriculum

Diabetes management requires consistently implementing adherence behaviors in a variety of settings. For some adolescents, consistency may be difficult due to problems in communication and assertiveness. The purpose of the present study was to evaluate the impact of a camp curriculum to teach assertive communication skills to adolescents with diabetes. The curriculum included didactic information, sharing of personal experiences, and role playing. Results showed a significant increase in adolescents' perceptions of their assertiveness from before to after the camp experience, an increase that was still apparent at a 3-month follow-up. No changes were reported in parental perceptions of their adolescents' degree of openness in communicating or in communication problems. In contrast, adolescents reported a significant decrease in their degree of openness in communicating with fathers, with a similar trend for mothers. These results suggest that the curriculum was successful in meeting the primary goal of enhancing the adolescents' assertive communication skills but had a questionable impact on their general communications with parents.

Hyperglycaemia, hypoglycaemia, and blood glucose control in diabetes: symptom perceptions and treatment strategies

Recent research has suggested that patients with Type 1 diabetes who are in chronically poor blood glucose control perceive hyperglycaemia differently from those who are in good control. To extend these observations 181 insulin-treated patients with Type 1 or Type 2 diabetes were studied. Patients completed a self-report questionnaire which included items concerning feelings about high and low blood glucose levels and strategies for maintaining blood glucose control. Glycosylated haemoglobin levels were also measured. We hypothesized that level of blood glucose control would: (1) be associated with perceptions of hyperglycaemia and treatment strategies for managing hyperglycaemia and (2) not be associated with perceptions and strategies concerning hypoglycaemia. In comparison with those in 'acceptable' or 'poor' blood glucose control, those in 'good' control perceived symptoms of hyperglycaemia at lower blood glucose levels (p less than 0.001) and felt physically best at lower blood glucose levels (p less than 0.001). They, also began treatment for hyperglycaemia at lower glucose levels (p less than 0.05), set lower minimal (p less than 0.001) and maximal (p less than 0.001) glucose levels as treatment goals, and tested their blood glucose levels more frequently (p less than 0.05). Among Type 1 diabetic patients, those in 'good' control reported experiencing hypoglycaemia at lower glucose levels than those in 'acceptable' or 'poor' control (p less than 0.05). No differences in treatment strategies of hypoglycaemic symptoms were apparent. This study suggests an influence of patients' perceptions of symptoms and treatment in self-care of diabetes.

Psychosocial correlates of hemoglobin Alc in young adults with type I diabetes

To determine whether psychosocial variables are related to long-term glycemic control; trait anxiety, depression, loneliness and life stress were assessed in 48 Type I diabetic patients. Hemoglobin A1c (HbA1c), an indicator of long-term glycemic utilization, was assayed from blood samples drawn shortly before the self-report instruments were administered. Of the psychosocial variables, anxiety was significantly related to current values of HbA1c. The association between anxiety and current HbA1c remained after statistically controlling for potentially confounding variables, including the previous value of HbA1c. Despite the stability of HbA1c values over time, anxiety scores were not significantly correlated with follow-up HbA1c. The implications of the significant relationships between psychological constructs and glycemic control are discussed.

The Rowdy Reactors: maintaining a support group for teenagers with diabetes

A successful support group for teenagers with type I diabetes requires more than informational lectures and discussions. Active learning by doing and the client's feeling of being in control are important. Attempts at gaining control require development of self-image, group solidarity, and the ability to communicate with nondiabetic peers and parents. Here is how one group did it.

Chronic poor metabolic control in the pediatric population: a stepwise intervention program

Improving metabolic outcomes in children and adolescents with IDDM who are in chronically poor metabolic control is one of the most difficult tasks confronting health care providers. These patients have clinical histories characterized by recurrent episodes of diabetic ketoacidosis and the persistance of acute disease symptoms. Complex psychosocial factors play a critical role in the genesis of chronic poor control, and patients are often resistant to standard interventions. To guide treatment of these difficult patients, we have developed a stepwise intervention program that addresses psycho social issues and provides strategies for improving metabolic control. The steps include documentation of patient response to insulin and the correction of educational deficiencies, defining and renegotiating the family care role, confronting families' inappropriate perceptions of care, and legal interventions. Previous evaluation has shown that appli cation of this approach can nearly eliminate recurrent episodes of diabetic ketoacidosis.

Psychologic predictors of compliance in children with recent onset of diabetes mellitus

A group of 57 children with recent onset of insulin-dependent diabetes mellitus was studied over 18 months. Compliance with the prescribed diabetic treatment deteriorated over this period. Adolescents (aged 13 to 15 years) were less compliant than preadolescents (aged 9 to 12 years). Initial patient reports of self-esteem, perceived competence, social functioning, behavioral symptoms, and their adjustment to diabetes predicted subsequent compliance behaviors. The findings highlight the linkage of child personality and adjustment with self-care of diabetes, and suggest that psychosocial assessment soon after diabetes is diagnosed may help identify patients at risk for later compliance problems.

Initial coping responses and psychosocial characteristics of children with insulin-dependent diabetes mellitus

School-aged children with newly diagnosed insulin-dependent diabetes mellitus (IDDM) were studied longitudinally in order to document how they adjusted to the medical illness and to assess salient background factors. The extent of life stress and the prevalence of psychiatric disorders that predated the IDDM were within normative ranges, and there was no characteristic preexisting "diabetic personality." The initial strain of living with IDDM elicited two general modes of coping. The prototypical and subdued reaction (seen in 64% of the children) consisted of mild sadness, anxiety, feeling of friendlessness, and social withdrawal. The rest of the children (36%) exhibited reactions that met criteria for a psychiatric disorder; depressive syndromes were the most common presentations. Anamnestic factors and the parents' initial responses to their children's IDDM were unrelated to how the children themselves coped. However, psychiatrically diagnosable reactions were more likely among children whose parents were of low socioeconomic status and had marital distress. Coping with the diagnosis and the early impact of IDDM took no more than 7 to 9 months, no matter how severe the child's response was initially.
