Barriers and strategies for oral medication adherence among children and adolescents with Type 2 diabetes. Diabetes Res Clin Pract 2018; 139:24-31. [PMID: 29427697 PMCID: PMC5955779 DOI: 10.1016/j.diabres.2018.02.001] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2017] [Revised: 01/08/2018] [Accepted: 02/01/2018] [Indexed: 12/11/2022]
Abstract
AIMS Examine barriers for taking glucose-lowering oral medications, associated baseline characteristics, strategies used, and the adherence impact in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study. METHODS We studied youth prescribed oral diabetes medications over two years (N = 611, 583, and 525 at 6, 12, and 24 months). Clinicians documented barriers (e.g. forgetting, routines, other concerns) in the subsample that reported missed doses (N = 423 [69.2%], 422 [72.4%], and 414 [78.9%] at 6, 12, and 24 months, respectively). Adherence strategies were also assessed (e.g. family, schedule, reminder device) using standard questions. Logistic regression was used to analyze associations with medication adherence. RESULTS Those missing doses were not different from the total sample (61.5% female, 13.9 ± 2.0 years, >80% racial/ethnic minorities). No baseline demographic or clinical predictors of barriers to medication adherence were identified. Among those for whom barriers were assessed, "forgetting" with no reason named (39.3%) and disruptions to mealtime, sleep, and schedule (21.9%) accounted for the largest proportion of responses. Family support was the primary adherence strategy identified by most youth (≥50%), followed by pairing the medication regimen with daily routines (>40%); the latter strategy was associated with significantly higher adherence rates (p = 0.009). CONCLUSIONS Family supported medication adherence was common in this mid-adolescent cohort, but self-management strategies were also in evidence. Findings are similar to those reported among youth with other serious chronic diseases. Prospective studies of multi-component family support and self-management interventions for improving medication adherence are warranted. TRIAL REGISTRATION ClinicalTrials.gov NCT00081328.

Abstract
AIMS To evaluate the psychometric properties of the Diabetes Management Questionnaire, a brief, self-report measure of adherence to contemporary diabetes management for young people with Type 1 diabetes and their caregivers. METHODS A total of 273 parent-child dyads completed parallel versions of the Diabetes Management Questionnaire. Eligible children (aged 8-18 years) had Type 1 diabetes for ≥1 year. A multidisciplinary team designed the Diabetes Management Questionnaire as a brief, self-administered measure of adherence to Type 1 diabetes management over the preceding month; higher scores reflect greater adherence. Psychometrics were evaluated for the entire sample and according to age of the child. RESULTS The children (49% female) had a mean ± sd (range) age 13.3 ± 2.9 (8-18) years and their mean ± sd HbA1c was 71 ± 15 mmol/mol (8.6 ± 1.4%). Internal consistency was good for parents (α = 0.83) and children (α = 0.79). Test-retest reliability was excellent for parents (intraclass correlation coefficient =0.83) and good for children (intraclass correlation coefficient = 0.65). Parent and child scores had moderate agreement (intraclass correlation coefficient = 0.54). Diabetes Management Questionnaire scores were inversely associated with HbA1c (parents: r = -0.41, P < 0.0001; children: r = -0.27, P < 0.0001). Psychometrics were stronger in the children aged ≥13 years compared with those aged < 13 years, but were acceptable in both age groups. Mean ± sd Diabetes Management Questionnaire scores were higher among children who were receiving insulin pump therapy (n = 181) than in children receiving multiple daily injections (n = 92) according to parent (75.9 ± 11.8 vs. 70.5 ± 15.5; P = 0.004) and child report (72.2 ± 12.1 vs. 67.6 ± 13.9; P = 0.006). CONCLUSIONS The Diabetes Management Questionnaire is a brief, valid self-report measure of adherence to contemporary diabetes self-management for people aged 8-18 years who are receiving either multiple daily injections or insulin pump therapy.

Abstract
AIMS To develop and validate the Diabetes Family Impact Scale, a scale to measure the impact of diabetes on families. METHODS The Diabetes Family Impact Scale was developed by an iterative process, with input from multidisciplinary diabetes providers and parents of children with Type 1 diabetes. The psychometric properties of the Diabetes Family Impact Scale were assessed in parents of children with Type 1 diabetes. This assessment included internal consistency, convergent validity and exploratory factor analysis. RESULTS Parents (n = 148) of children (mean ± sd age 12.9 ± 3.3 years) with Type 1 diabetes (mean ± sd duration 6.2 ± 3.6 years) completed the 15-item Diabetes Family Impact Scale. After eliminating one item, the 14-item measure demonstrated good internal consistency (Cronbach's α = 0.84). Correlations between the Diabetes Family Impact Scale and measures of parent diabetes burden (r = 0.48, P < 0.0001), stressful life events (r = 0.28, P = 0.0007), and child's quality of life (r = -0.52 and -0.54, P < 0.0001 for generic and diabetes-specific quality of life, respectively) supported the convergent validity of the instrument. Factor analysis identified four factors corresponding to the four survey domains (school, work, finances and family well-being). CONCLUSIONS The Diabetes Family Impact Scale measures diabetes-specific family impacts with good internal consistency and convergent validity and may be a useful tool in clinical and research settings.

Relationships of neophobia and pickiness with dietary variety, dietary quality and diabetes management adherence in youth with type 1 diabetes. Eur J Clin Nutr 2014; 68:131-6. [PMID: 24253761 PMCID: PMC4165343 DOI: 10.1038/ejcn.2013.239] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2013] [Revised: 09/09/2013] [Accepted: 10/07/2013] [Indexed: 01/24/2023]
Abstract
BACKGROUND/OBJECTIVES Neophobia, pickiness and diet variety are associated with diet quality and health outcomes in young children. Limited research has examined these associations among youth with type 1 diabetes (T1D), a population at risk for poor health outcomes when dietary quality is inadequate. SUBJECTS/METHODS Youth (n=252, age 13.2 ± 2.8 years, 92% white, diabetes duration 6.3 ± 3.4 years) with T1D and their parents completed 3-day youth diet records; parents completed questionnaires regarding youth neophobia, pickiness and diabetes management adherence. Medical records provided biomedical data. Dietary quality indicators included Nutrient-Rich Foods Index 9.3 (NRF9.3), Healthy Eating Index-2005 (HEI-2005), Whole Plant Food Density (WPFD) and key single nutrients. Dietary variety was operationalized as a count of 20 recommended food groups consumed. Relationships of dietary quality and diabetes management adherence with neophobia, pickiness and dietary variety as independent variables were examined using multiple linear regression analyses adjusted for total energy intake, age, height and weight. RESULTS In multiple linear regression analyses, NRF9.3 and HEI-2005 were each inversely associated with neophobia and pickiness, and positively associated with dietary variety. WPF and potassium were each positively associated and saturated fat was inversely associated with dietary variety. However, in models simultaneously including neophobia, pickiness and dietary variety as independent correlates of dietary quality, only relationships with dietary variety remained significant. Diabetes management adherence was negatively associated with both neophobia and pickiness and positively associated with dietary variety. CONCLUSIONS Findings suggest that increasing dietary variety may contribute toward improved dietary quality among youth with T1D, despite potentially adverse influences of neophobia and pickiness.

Abstract
AIMS To evaluate parents' goals and parents' perceptions of physicians' goals for blood glucose and HbA(1c) in children and adolescents with Type 1 diabetes. METHODS In a cross-sectional observational assessment, parents (80% mothers) of 153 children/adolescents (56% female), aged 12.9 ± 2.3 years (range 8-16 years) with Type 1 diabetes for 6.3 ± 3.5 years, completed surveys regarding their goals and their perceptions of physicians' goals for their child's blood glucose and HbA(1c) levels. RESULTS Children/adolescents had a mean HbA(1c) of 69 ± 16 mmol/mol (8.4 ± 1.4%) and checked blood glucose levels 3.8 ± 1.2 times/day; 23% received pump therapy. Almost half of parents reported a blood glucose goal of 130 (80-180) mg/dl [7.2 (4.4-10) mmol/l]; 75% of parents reported a HbA(1c) goal of 42-64 mmol/mol (6-8%). HbA(1c) was significantly lower when parents reported HbA(1c) goals ≤ 64 mmol/mol (≤ 8%) vs. > 64 mmol/mol (> 8%) [67 ± 14 mmol/mol (8.3 ± 1.2%) vs. 76 ± 20 mmol/mol (9.1 ± 1.8%), respectively, P = 0.02]. Parents' blood glucose and HbA(1c) goals were tightly linked with parents' perceptions of physicians' blood glucose and HbA(1c) goals (69% concordant, P < 0.0001; 88% concordant, P < 0.0001, respectively). CONCLUSIONS There was a significant association between lower parent HbA(1c) goals and lower child/adolescent HbA(1c) . Further, parents appear to set glycaemic goals based upon their perceptions of physician goals. Future studies should assess the relationship between parents' perceptions of health-care providers' goals and health-care providers' actual goals and the impact of unified family/provider goal-setting on glycaemic control.

Abstract
The objective of this study was to examine associations of food preferences and availability with dietary intake in youth with type 1 diabetes, for whom dietary intake and quality are essential to disease management. Youth (n=252, age 13.2±2.8 y, diabetes duration 6.3±3.4 y) reported preferences and parents reported household availability for 61 food items categorized as fruit, vegetables, whole grains, refined grains and fats/sweets. Youth energy-adjusted daily servings of food groups, Healthy Eating Index-2005 and Nutrient Rich Foods 9.3 scores were calculated from 3-day diet records. Associations of dietary intake and quality variables with preference and availability of all food groups were evaluated by linear regressions adjusted for sociodemographic characteristics. Fruit and whole grain intake were positively related to corresponding preference and availability; whole grain intake and refined grain availability were inversely related. Vegetable, refined grain and fats/sweets intake were unrelated to preference and availability. Diet quality measures were related positively to fruit preference and whole grain availability and inversely to refined grains availability. Findings indicate associations of dietary intake with food preference and availability vary by food group in youth with type 1 diabetes. Measures of overall dietary quality were more consistently associated with food group availability than preferences.

Abstract
AIMS In a pediatric patients, the burden of diabetes lies within the family. In the current era of intensive insulin therapy, perceived parental burden may affect the family's efforts at effective diabetes management. The aims of this study were to re-examine and revise a measure of perceived parental burden associated with caring for a child with diabetes in the current era. METHODS A geographically diverse population of young people (N = 376) with Type 1 diabetes and their parents included participants in the Juvenile Diabetes Research Foundation continuous glucose monitoring study and patients from the Joslin Diabetes Center. Participants provided data on demographics, diabetes management, diabetes-specific family conflict, and quality of life at baseline and after 6 months of follow-up. RESULTS Young people were 12.9 ± 2.7 years old with diabetes duration of 6.3 ± 3.5 years. Mean HbA(1C) was 8.0 ± 1.2%(64 mmol/mol), 58% received insulin pump therapy, and young people monitored blood glucose 5.2 ± 2.3 times/day. Factor analysis yielded two factors, 'Immediate Burden' and 'Theoretical Burden'. The Problem Areas in Diabetes Survey - Parent Revised version (PAID-PR) demonstrated excellent internal consistency (Cronbach's α = 0.87; factor 1 α = 0.78; factor 2 α = 0.83). Greater parental burden was associated with more frequent blood glucose monitoring, higher HbA(1C) levels, greater diabetes-specific family conflict, and lower quality of life. Test-retest analysis was acceptable (r = 0.62). CONCLUSIONS The PAID-PR demonstrated excellent internal consistency, good test-retest reliability, and associations with diabetes-specific family conflict and quality of life. This brief measure may have both clinical and research utility in the management of young people with Type 1 diabetes.

Abstract
AIMS Young adulthood is a challenging period for patients with Type 1 diabetes as developmental changes complicate Type 1 diabetes management and gaps in care may arise as patients transition from paediatric to adult providers. This period has been associated with worsening diabetes outcomes. One approach to aid young adults during this transition period could entail professionally led support groups to enhance self-motivation and facilitate peer-to-peer interactions. We implemented and evaluated a support group for young adults with Type 1 diabetes as a pilot project. METHODS Young adults with Type 1 diabetes (18-30 years) participated in monthly, professionally led support groups for 5 months. Questionnaires were completed pre- and post-group and chart review data were collected regarding glycaemic control and visit frequency in the year before and after group participation. RESULTS Participation in the group was associated with improvement in HbA(1c) and decreased self-reported diabetes burden, along with a trend for an increase in diabetes-related self-care behaviours. Frequency of visits did not vary from pre- to post-group. Discussion topics identified by participants included managing diabetes in day-to-day life, experiences and interactions with others who do not have diabetes and emotions related to diabetes. Participants identified that they sought a diabetes care team that offers knowledge, support and a multidisciplinary team. CONCLUSIONS Professionally led support groups may have utility for increasing social support and optimizing diabetes outcomes in young adults with Type 1 diabetes.

Abstract
AIMS Point-of-care HbA(1c) is routine in clinical practice. Comparison of point-of-care HbA(1c) against laboratory measurements across sites and over time is warranted. METHODS One hundred and twenty-one young persons with Type 1 diabetes from four centres provided 450 paired samples collected over 10 months for point-of-care HbA(1c) and central laboratory-based high-performance liquid chromatography (HPLC) HbA(1c) determinations. Change in HbA(1c) over time was assessed by difference from initial to final HbA(1c) and by growth modelling with annualized slope calculation. Change in HbA(1c) was categorized as improved (decrease of ≥ 0.5% or negative slope), no change (± 0.4% of initial HbA(1c) or slope = 0) or worsened (increase of ≥ 0.5% or positive slope). RESULTS The 450 paired samples (median of four pairs/patient) were highly correlated (r = 0.97, P < 0.0001), as were time-specific and site-specific pairs (r = 0.94 to 0.98, P < 0.0001). Initial-to-final point-of-care HbA(1c) and HPLC HbA(1c) changes were 0.3 ± 1.1% (range -2.7 to 4.1) and 0.4 ± 1.2% (-3.9 to 4.5), respectively, with 21% of patients (n = 26) discordant for change categories. ΔHbA(1c) by point-of-care HbA(1c) vs. HPLC HbA(1c) differed across the HbA(1c) range and by ≥ 0.5% absolute difference in ΔHbA(1c) in 14 (54%) of the 26 patients discordant for HbA(1c) change categories. Mean annual HbA(1c) slope was 0.4 ± 1.5% (-5.4 to 4.8) for point-of-care HbA(1c) and 0.4 ± 1.6% (-6.9 to 5.2) for HPLC HbA(1c), with 18% (n = 22 pairs) discordant for change categories. CONCLUSIONS Assessment of absolute HbA(1c) change may not be different for point-of-care HbA(1c) compared with HPLC HbA(1c); however, misclassification of patients by discrete cut-off values may occur with point-of-care HbA(1c) compared with HPLC HbA(1c) determinations.

Abstract
AIMS Adherence to diabetes-related tasks is an important construct. The Diabetes Self-Management Profile is a validated, semi-structured interview assessing adherence in paediatric patients with Type 1 diabetes. We created and validated a brief questionnaire version of the Diabetes Self-Management Profile called the Diabetes Self-Management Questionnaire. METHODS Young people with Type 1 diabetes, ages 9-15 years (n = 338) and their parents provided data from chart review, interview and questionnaires. RESULTS Diabetes Self-Management Questionnaire scores correlated significantly with Diabetes Self-Management Profile scores, HbA(1c) , blood glucose monitoring frequency and other measures associated with adherence and/or glycaemic control (P ≤ 0.01 for all). Young people and parent scores were correlated (r = 0.55, P < 0.0001). The Diabetes Self-Management Questionnaire demonstrated modest internal consistency (Cronbach's α = 0.59), adequate for a brief measure of multidimensional adherence. In addition, factor analysis confirmed one factor. CONCLUSIONS This brief adherence questionnaire demonstrated construct validity in young people 9-15 years old and their parents and may have utility in clinical and research settings.

Abstract
AIMS To describe satisfaction with continuous glucose monitoring in Type 1 diabetes; to correlate continuous glucose monitoring satisfaction scores with usage; and to identify common themes in perceived benefits and barriers of monitoring reported by adults, youths and the parents of youths in the Juvenile Diabetes Research Foundation continuous glucose monitoring trials. METHODS The Continuous Glucose Monitoring Satisfaction Scale questionnaire was completed after 6 months of monitoring. Participants also answered open-ended queries of positive and negative attributes of continuous glucose monitoring. RESULTS More frequent monitoring was associated with higher satisfaction for adults (n = 224), youths (n = 208) and parents of youths (n = 192) (all P < 0.001) in both the 'benefits' and 'hassles' sub-scales of the Continuous Glucose Monitoring Satisfaction Scale, but the greatest differences between the two groups involved scores on hassle items. Common barriers to monitoring use included insertion pain, system alarms and body issues; while common benefits included glucose trend data, opportunities to self-correct out-of-range glucose levels and to detect hypoglycaemia. CONCLUSIONS As frequent use of continuous glucose monitoring is associated with improved glycaemic control without increased hypoglycaemia it is important to overcome barriers, reinforce benefits and set realistic expectations for this technology in order to promote its more consistent and frequent use in individuals with Type 1 diabetes.

Abstract
AIMS To determine the occurrence of microalbuminuria in young people with Type 1 diabetes mellitus followed prospectively for 2 years and to relate the presence of persistent elevations in urinary albumin excretion (UAE) to age, diabetes duration, puberty and other factors. METHODS During a 2 year period, random urine samples were obtained from 471 patients, aged 8-18 years (mean +/-sd 12.9 +/- 2.3 years) with Type 1 diabetes duration 5.6 +/- 3.0 years, as part of routine clinical care. Urine albumin and creatinine concentrations were measured in 1310 samples (median, 3 samples per patient) and the albumin:creatinine ratio was calculated (in micrograms albumin per milligram creatinine). Height, weight, blood pressure (BP), glycated haemoglobin (HbA(1c)), blood glucose monitoring frequency and Tanner staging were collected from patients' medical records. RESULTS Twenty-three per cent of patients had one or more sample with elevated UAE (> or =20 microg/mg) and 9.3% had persistent elevations (> or =2 samples > or =20 microg/mg). Those with and without persistent microalbuminuria did not differ significantly in age, diabetes duration, z-score for body mass index, pubertal status or BP percentile. Ten per cent of children <13 years old and 9% of children > or =13 years old had persistent microalbuminuria. Persistent microalbuminuria was significantly associated with diabetes duration only in older children (duration 0.5-3 years, 4%; 4-6 years, 8%; > or =7 years, 14%; P = 0.02, trend test). Mean HbA(1c) over the 2 years was 8.7 +/- 1.2%. In a logistic regression model, mean HbA(1c) was the only significant predictor of persistent microalbuminuria (odds ratio 1.3, 95% confidence interval 1.0-1.6, P = 0.05). CONCLUSIONS Microalbuminuria in older children with Type 1 diabetes is likely to be clinically significant. In younger children, it may reflect functional, reversible renal changes. Longitudinal analysis is needed to confirm the probable transient nature of microalbuminuria in young patients with Type 1 diabetes.

Abstract
AIMS Increased body weight and disordered eating attitudes/behaviours are common in adolescent girls with Type 1 diabetes (T1D). Disordered eating increases risks for diabetes-related complications. This study aimed to identify a rapid screening approach for disordered eating attitudes and behaviours in adolescent girls with T1D and to examine the relationship between disordered eating and body weight in this population. METHODS Ninety adolescent girls, aged 12-19 years, provided a self-assessment of weight status. Participants also completed questionnaires to assess attitudes/behaviours toward food and eating, appetitive responsiveness to the food environment, disinhibition in eating and weight history. RESULTS Forty-three per cent of participants reported a history of overweight. Compared with participants who reported never being overweight, those who reported ever being overweight were significantly older, scored significantly higher on all measures of disordered eating attitudes/behaviours (P < or = 0.009) and were 4.8 times more likely to be currently overweight or obese (P < 0.001). Glycated haemoglobin (HbA(1c)) was similar between those who did and did not report ever being overweight. CONCLUSIONS Because of the ill-health effects of disordered eating and the higher rate of overweight in adolescent girls with T1D, effective screening tools are warranted. The single question 'Have you ever been overweight?' may be sufficient as a first question to screen for those at high risk for disordered eating attitudes/behaviours and to provide early intervention and prevention.

Abstract
AIMS Diabetes-specific family conflict is associated with suboptimal adherence and glycaemic control. Little is known about the individual and family factors associated with diabetes-specific family conflict. The purpose of this study was to examine whether background factors (e.g. age, gender), diabetes variables (e.g. duration of diabetes, adherence, glycaemic control) and psychological distress (i.e. depression and anxiety) in parents and children and adolescents were associated with diabetes-specific family conflict. METHODS Participants were 187 children and adolescents with Type 1 diabetes and their parents. Study measures assessed diabetes-specific family conflict, youth depression and parent depression and anxiety. Demographic and disease-specific data (adherence, glycaemic control) were also collected. RESULTS Findings suggested a close link between psychological distress in parents and children and adolescents and reports of increased diabetes-specific family conflict. In the presence of suboptimal glycaemic control, children and adolescents and parents reported more family conflict. Adherence was not significantly associated with family conflict. CONCLUSIONS This study highlights the importance of considering the impact of individual psychological functioning on family conflict and also suggests a bidirectional relationship between conflict and glycaemic control.

METHODS The instruments were completed by 447 children age 9 to 15.5 years with Type 1 diabetes > 1 year from four US paediatric diabetes clinics; parents completed the parallel parent-proxy measures. Principal components factor analysis was used to examine the factor structure of the PedsQL diabetes module. Analyses of the generic and diabetes QOL measures included psychometric properties, parent-child correlations and correlations with depression, adherence and glycated haemoglobin (HbA(1c)). RESULTS The factor structure of the PedsQL diabetes module did not support the original five subscales. Both one- and two-factor models were supported; however, parallel parent and child subscales did not emerge. While the generic and diabetes-specific measures of QOL were moderately to highly correlated with each other, the constructs were differentially associated with relevant diabetes outcomes. Generic QOL was more highly associated with depression than diabetes QOL. Conversely, diabetes QOL was more highly associated with adherence and HbA(1c), although this was seen to a greater extent for parent-proxy report than for child report. CONCLUSIONS Factor analysis of the PedsQL diabetes module supports the use of a total diabetes QOL score. Findings regarding the associations of the generic and diabetes modules with diabetes outcomes underscore the unique contribution provided by both generic and diabetes QOL.

Abstract
AIMS Diabetic ketoacidosis (DKA), a life-threatening acute complication of Type 1 diabetes, may be preventable with frequent monitoring of glycaemia and ketosis along with timely supplemental insulin. This prospective, two-centre study assessed sick day management using blood 3-hydroxybutyrate (3-OHB) monitoring compared with traditional urine ketone testing, aimed at averting emergency assessment and hospitalization. METHODS One hundred and twenty-three children, adolescents and young adults, aged 3-22 years, and their families received sick day education. Participants were randomized to receive either a blood glucose monitor that also measures blood 3-OHB (blood ketone group, n = 62) or a monitor plus urine ketone strips (urine ketone group, n = 61). All were encouraged to check glucose levels > or = 3 times daily and to check ketones during acute illness or stress, when glucose levels were consistently elevated (> or = 13.9 mmol/l on two consecutive readings), or when symptoms of DKA were present. Frequency of sick days, hyperglycaemia, ketosis, and hospitalization/emergency assessment were ascertained prospectively for 6 months. RESULTS There were 578 sick days during 21,548 days of follow-up. Participants in the blood ketone group checked ketones significantly more during sick days (276 of 304 episodes, 90.8%) than participants in the urine ketone group (168 of 274 episodes, 61.3%) (P < 0.001). The incidence of hospitalization/emergency assessment was significantly lower in the blood ketone group (38/100 patient-years) compared with the urine ketone group (75/100 patient-years) (P = 0.05). CONCLUSIONS Blood ketone monitoring during sick days appears acceptable to and preferred by young people with Type 1 diabetes. Routine implementation of blood 3-OHB monitoring for the management of sick days and impending DKA can potentially reduce hospitalization/emergency assessment compared with urine ketone testing and offers potential cost savings.

Abstract
AIM Our recent studies revealed a striking but variable enhancement of renal vasodilator responses to blockers of the renin-angiotensin system in subjects with diabetes mellitus, possibly reflecting the level of intrarenal activation of the renin-angiotensin system, and thus a risk of nephropathy. As obesity is a common finding in diabetic individuals, and obesity has been linked to an increase in plasma angiotensinogen levels, we enrolled diabetic subjects with a wide range of body mass index (BMI) for this study. METHODS Twelve Type 2 diabetic subjects in balance on a low sodium diet participated after baseline renal plasma flow and glomerular filtration measurements were made. Each subject then received 150 mg irbesartan, and renal function was measured every 45 min for 4 h. RESULTS The average vasodilator response to irbesartan was 174 +/- 33 ml/min. No correlation was found between renal plasma flow response to irbesartan and duration of diabetes, baseline glucose, or HbA1c level. BMI, our measure of obesity, was highly correlated to the renal response to irbesartan (r = 0.7; P = 0.01). CONCLUSIONS Our findings suggest an important role for obesity in activating the intrarenal renin system, perhaps via production of angiotensinogen. BMI may be an indicator of risk of nephropathy.

Abstract
AIMS Behavioural support around diabetes management tasks is linked to glycaemic outcomes. In this study we investigated the relationship between diabetes-related parental behaviours (conflict around and involvement in treatment tasks), adherence to blood glucose monitoring (BGM), and glycaemic control in youth with short duration Type 1 diabetes mellitus (DM). METHODS In a cross-sectional study, 104 youth (aged 8-17 years, duration of Type 1 DM 0.5-6 years) along with a parent, completed the Diabetes Conflict Scale. Parental involvement in management tasks was assessed with structured interviews and the Diabetes Family Responsibility Questionnaire. Adherence to BGM was evaluated by family report and by independent clinician rating. Glycaemic control was assessed with glycosylated haemoglobin (HbA1c) (ref. range, 4-6%). RESULTS Children (8-12 years; n = 69) and adolescents (13-17 years; n = 35), respectively, had similar durations of diabetes (x +/- sd; 2.7 +/- 1.69, 2.4 +/- 1.32 years) and similar glycaemic control (8.3 +/- 1.1%, 8.4 +/- 1.1%). In both age groups, parental involvement was a significant predictor of adherence to BGM (P = 0.01). Multivariate analyses, controlling for age, sex, disease duration, and BGM adherence, revealed that higher diabetes conflict significantly related to poorer glycaemic control (HbA1c) (R2 = 0.17; P < 0.01). CONCLUSIONS These findings indicate that in this cohort, early in the course of diabetes, diabetes-specific conflict and adherence to BGM became strongly linked to the child's glycaemic control. This suggests that to insure optimal control, it may be beneficial to introduce targeted interventions to build positive family involvement and interaction around diabetes tasks early in the disease course, before negative behaviours become established.

Abstract
Illness and stress are common occurrences. For the person with type 1 diabetes, these events can be triggers for counterregulation and [table: see text] subsequent metabolic deterioration if there is no attention to diabetes management tasks. Sick-day management requires increased monitoring of blood glucose and assessment for ketosis. Although urine testing for ketones has been the standard approach to sick-day management, new technology for self-monitoring of blood 3HB levels is now available. According to the American Diabetes Association, blood measurement of 3HB "may offer a useful alternative to urine ketone testing." This new technology may provide an opportunity to improve the management of uncontrolled diabetes and sick days in an attempt to reduce the human and economic burden of DKA.

Abstract
OBJECTIVE Although retinopathy is a common microvascular complication of type 1 diabetes, the mechanism for this complication is still unknown. Changes in retinal circulation have been noted before the development of overt retinal pathology. Because von Willebrand factor (vWF) is a marker for endothelial dysfunction and mediates platelet adhesion, we determined if there was an association between vWF and retinal circulation in the early stages of diabetic retinopathy. RESEARCH DESIGN AND METHODS Twenty subjects (aged 32.4 +/- 7.8 years) with type 1 diabetes and minimal or no retinopathy were studied. The mean duration of diabetes was 4.7 +/- 2.6 years. Data were collected at baseline and after 4 months of 1,800 IU vitamin E therapy or placebo. Retinal circulation was evaluated by video fluorescein angiography. Plasma vWF antigen levels were measured by enzyme-linked immunosorbent assay and fibrinogen by the Clauss method. RESULTS Retinal blood flow was negatively correlated with vWF levels (r = -0.44, P = 0.008), whereas retinal circulation time was positively correlated with vWF levels (r = 0.33, P = 0.048). Fibrinogen levels were not significantly associated with either retinal index. However, fibrinogen levels were positively associated with HbA1c levels (r = 0.34, P = 0.01), indicating an association between poor glycemic control and higher fibrinogen levels. CONCLUSIONS Increased vWF was associated with a prolonged retinal circulation time and reduced retinal blood flow in early-stage retinopathy of type 1 diabetes. Reduced blood flow associated with increased vWF levels may promote stasis in the retinal circulation and lead to local hypoxemia. These changes might contribute to the microvascular complications of diabetes. Whether the vWF levels predict retinal complications deserves further investigation.

Abstract
Ketone bodies are produced by the liver and used peripherally as an energy source when glucose is not readily available. The two main ketone bodies are acetoacetate (AcAc) and 3-beta-hydroxybutyrate (3HB), while acetone is the third, and least abundant, ketone body. Ketones are always present in the blood and their levels increase during fasting and prolonged exercise. They are also found in the blood of neonates and pregnant women. Diabetes is the most common pathological cause of elevated blood ketones. In diabetic ketoacidosis (DKA), high levels of ketones are produced in response to low insulin levels and high levels of counterregulatory hormones. In acute DKA, the ketone body ratio (3HB:AcAc) rises from normal (1:1) to as high as 10:1. In response to insulin therapy, 3HB levels commonly decrease long before AcAc levels. The frequently employed nitroprusside test only detects AcAc in blood and urine. This test is inconvenient, does not assess the best indicator of ketone body levels (3HB), provides only a semiquantitative assessment of ketone levels and is associated with false-positive results. Recently, inexpensive quantitative tests of 3HB levels have become available for use with small blood samples (5-25 microl). These tests offer new options for monitoring and treating diabetes and other states characterized by the abnormal metabolism of ketone bodies.

Abstract
OBJECTIVE To determine the effectiveness of vitamin E treatment in normalizing retinal blood flow and renal function in patients with <10 years of type 1 diabetes. RESEARCH DESIGN AND METHODS An 8-month randomized double-masked placebo-controlled crossover trial evaluated 36 type 1 diabetic and 9 nondiabetic subjects. Subjects were randomly assigned to either 1,800 IU vitamin E/day or placebo for 4 months and followed, after treatment crossover, for a further 4 months. Retinal blood flow was measured using video fluorescein angiography, and renal function was assessed using normalized creatinine clearance from timed urine collections. RESULTS After vitamin E treatment, serum levels of vitamin E were significantly elevated (P<0.01) in both type 1 diabetic and control patients. Hemoglobin A1c was not affected by vitamin E treatment. Diabetic patient baseline retinal blood flow (29.1+/-7.5 pixel2/s) was significantly (P = 0.030) decreased compared with that of nondiabetic subjects (35.2+/-7.2 pixel2/s). After vitamin E treatment, diabetic patient retinal blood flow (34.5+/-7.8 pixel2/s) was significantly increased (P<0.001) and was comparable with that of nondiabetic subjects. Additionally, vitamin E treatment significantly (P = 0.039) normalized elevated baseline creatinine clearance in diabetic patients. CONCLUSIONS Oral vitamin E treatment appears to be effective in normalizing retinal hemodynamic abnormalities and improving renal function in type 1 diabetic patients of short disease duration without inducing a significant change in glycemic control. This suggests that vitamin E supplementation may provide an additional benefit in reducing the risks for developing diabetic retinopathy or nephropathy.

Abstract
OBJECTIVES The goal of this study was to identify parental behaviors that relate to adherence and metabolic control in a population of young adolescents with insulin-dependent diabetes mellitus (IDDM), and to understand the interrelationships among the variables of parental involvement, adherence to blood glucose monitoring, and glycemic control. STUDY DESIGN A cross-sectional design was used to investigate parental involvement in diabetes regimen tasks in 89 youth, aged 10 to 15 years, with IDDM. Levels of parental involvement in blood glucose monitoring (BGM) and insulin administration were evaluated through interviews. Assessment of adherence was made by physicians or nurses, independent of patient or parent reports of adherence. Glycemic control was assessed with glycosylated hemoglobin (HbA1c) (reference range, 4% to 6%). RESULTS There were significant differences in the mean HbA1c values between the older (13 to 15 years of age) (HbA1c = 8.9% +/- 1.03%) and younger (10 to 12 years) patients (HbA1c = 8.4% +/- 1.06%) (p < 0.02). Parental involvement in BGM was significantly related to adherence to BGM (number of blood sugar concentrations checked daily) in both groups of adolescent patients. The younger patients monitored their blood glucose levels more frequently than did the older patients, 39% of the younger patients checked sugar concentrations four or more times daily compared with only 10% of the older group (p < 0.007). In a multivariate model controlling for age, gender, Tanner staging, and duration of diabetes, the frequency of BGM was a significant predictor of glycemic control (R2 = 0.19, p < 0.02). Increased frequency of BGM was associated with lower HbA1c levels. When the frequency of BGM was zero or once a day, the mean HbA1c level was 9.9% +/- 0.44 (SE); when the frequency of BGM was two or three times a day, the mean HbA1c level was 8.7% +/- 0.17; and when the frequency of BGM was four or more times daily, the mean HbA1c level was 8.3% +/- 0.22. CONCLUSIONS Parental involvement in BGM supports more frequent BGM in 10- to 15-year-old patients with IDDM. This increased adherence to BGM is associated with better metabolic control (i.e., lower HbA1c levels). These findings suggest that encouraging parental involvement in BGM with 10- to 15-year-old patients with IDDM may help to prevent the well-documented deterioration in glycemic control and adherence to treatment that often occurs in later adolescence.

Abstract
The objective of this study was to determine the prevalence of stages of diabetic nephropathy, defined by the albumin/creatinine ratio (AC ratio) in repeated measurements in random urine samples. Over a 30-month interval, 1613 patients with Type I diabetes (IDDM) (aged 15 to 44 yr, IDDM duration 1 to 39 yr), and 218 healthy control subjects provided multiple urine specimens. AC ratios measured in urine samples taken 5 months apart were highly reproducible (Spearman r = 0.83). A criterion for the boundary between normoalbuminuria and microalbuminuria was obtained by searching for a cutpoint that optimized agreement between serial specimens on individuals. The result was lower in men than women: 17 as compared with 25 micrograms/mg. These two values corresponded to the 95th percentiles of the respective distributions of the AC ratio in healthy control subjects. Also these sex-specific cutpoints, when converted to albumin excretion rates, became almost equal: 30 and 31 micrograms/min. Microalbuminuria appeared early in the course of IDDM (6% of those with only 1 to 3 yr of diabetes) and then increased rapidly during two intervals, the first and third decades, before leveling off at 52%. By that time the cumulative risk of overt proteinuria had risen to 27%. Determinations of the AC ratio in random urine samples are easily obtained and are reliable indices of elevated urinary albumin excretion (microalbuminuria) in IDDM. The pattern of occurrence of microalbuminuria according to duration of IDDM suggests that there may be two subsets of diabetic nephropathy, one appearing early and the other late. Patients with microalbuminuria and 25 yr of postpubertal IDDM have low risk of progression to advanced diabetic nephropathy.

Abstract
Apolipoprotein E (apoE) plays an important role in plasma lipid metabolism. Three common isoforms of this protein have been identified by the isoelectric focusing method. In this report we describe a new method for distinguishing these isoforms. Our method employs PCR amplification of the DNA sequence of exon 4 in the apoE gene followed by denaturing gradient gel electrophoresis (DGGE) to distinguish its different melting characteristics. Identification of the ApoE isoforms through DNA melting behavior rather than protein charge differences eliminates the problems associated with isoelectric focusing and facilitates screening for additional mutations at the apoE locus.
