Personal and family factors associated with quality of life in adolescents with diabetes

Diabetes-specific family conflict and psychological distress in paediatric Type 1 diabetes

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.

Health-related quality of life in intensively treated young patients with type 1 diabetes

This study aimed to analyse the impact of the disease and treatment on health-related quality of life (HRQOL) in intensively treated young patients with diabetes. Our main hypothesis was that metabolic control, gender, age and socio-economic status predict HRQOL. All children and adolescents (n = 400, 191 girls) and parents in a geographic population of two paediatric clinics in Sweden [mean age 13.2 yr, +/-SD 3.9, range 2.6-19.6; mean duration of diabetes 5.1 yr, +/-SD 3.8, range 0.3-17.6; yr mean haemoglobin A1c (HbA1c) 7.1%, +/-SD 1.2, range 4.0-10.7] received the DISABKIDS questionnaire, a validated combined chronic generic and condition-specific HRQOL measure for children, and the EuroQol-5D questionnaire. Parents as proxy perceived HRQOL lower than their children. Adolescents with separated parents reported lower generic HRQOL (GeHRQOL) and diabetes-specific HRQOL (DiHRQOL) than those with parents living together (p = 0.027 and p = 0.043, respectively). Adolescent girls reported lower GeHRQOL (p = 0.041) and DiHRQOL (p = 0.001) than boys did. Parents of girls <8 yr of age reported lower DiHRQOL (p = 0.047) than did parents of boys <8 yr. In addition, a difference was found in HRQOL between centres. Intensive insulin therapy did not seem to lower HRQOL. If anything, along with better metabolic control, it increased HRQOL. A correlation between DiHRQOL and HbA1c was found in adolescents (r = -0.16, p = 0.046) and boys aged 8-12 yr (r = -0.28, p = 0.045). We conclude that the diabetes team can influence the HRQOL of the patients as there was a centre difference and because HRQOL is influenced by glycaemic control and insulin regimen. Girls seem to need extra support.

Adherence and glycemic control among Hispanic youth with type 1 diabetes: role of family involvement and acculturation

OBJECTIVE

To assess whether family involvement and acculturation were related to adherence and glycemic control among Hispanic youth with type 1 diabetes (T1D).

METHODS

Hispanic youth with T1D (n = 111; M age = 13.33; 53% female) and parents completed questionnaires that assessed diabetes-related family involvement (distribution of responsibility for diabetes, family support for diabetes), acculturation (linguistic acculturation, generational status), and adherence. HbA1c levels indexed glycemic control.

RESULTS

Better adherence was associated with less adolescent independent responsibility, more family support for diabetes, and more recent immigration (fewer generations of the family living in US). Family support mediated the relationship between responsibility and adherence. Better glycemic control was associated with higher levels of parental education and adherence.

CONCLUSIONS

Family support for diabetes is important for adherence among Hispanic youth with T1D. Research should examine aspects of recent immigration that contribute to better adherence and the impact of supportive interventions on diabetes care.

Study of the factors affecting health-related quality of life in adolescents after liver transplantation

The aim of the study was to identify factors affecting health-related quality of life (HRQL) in adolescents after liver transplantation. HRQL was measured using the CHQ-CF87 in 55 adolescents, aged 12-18 years. Factors associated with HRQL included allograft morbidity, psychological and family-related variables measured through standardized questionnaires. The domains of the CHQ-CF87 were reduced using factor analysis to give physical, psychological and social domains. Impacting factors were identified through stepwise, multiple regression analysis. Adolescents had significantly lower HRQL in every domain except for role/social-behavior and family cohesion compared to the general population. Adolescents experienced median 18 (range 4-31) symptoms related to immunosuppression, 40(75%) had one or more chronic illnesses related to immunosuppression and 12(22%) had a history of emotional difficulties. Self-esteem and emotional health were similar to the general population but behavior and aspects of family function were lower. Following regression analysis, the factors associated with HRQL were: age at transplant, secondary chronic illness, symptom distress, headaches, history of emotional difficulties, self-esteem and family conflict. These explained 57% of the variance in physical function, 61% of psychological function and 39% of social function. HRQL is significantly reduced in adolescents after transplantation, which could be related to immunosuppression and psychosocial factors.

Parenting children with diabetes: exploring parenting styles on children living with type 1 diabetes mellitus

PURPOSE

The purpose of this study was to examine the extent to which parenting styles is associated with diabetes control in children (aged 5-12 years) with type 1 diabetes, and on child and parent quality of life.

METHODS

Data were collected from a total of 216 parent and child dyads, from 4 pediatric diabetes clinics in southern Ontario, using a cross-sectional survey methodology. Each parent and child independently completed the questionnaires. The study instruments included the Parenting Dimensions Inventory, Pediatric Quality of Life (diabetes specific), and chart reviews for glycosylated hemoglobin (A1C) levels.

RESULTS

The results of the study demonstrated that parenting styles were not correlated with diabetes control and were weakly correlated with quality of life. Most parents reported behaviors of authoritative or democratic parenting. The mean glycosylated hemoglobin (A1C) for children in the study was slightly above optimal target range, at 8.4%. Parental education had a weak negative correlation with diabetes control.

CONCLUSIONS

Parenting styles are not associated with diabetes control and quality of life in children with type 1 diabetes. However, further research should assess the impact of the determinants of parenting on children with type 1 diabetes and quality of life.

Generic and diabetes-specific parent-child behaviors and quality of life among youth with type 1 diabetes

OBJECTIVE

To evaluate associations among parent-child behaviors and generic and diabetes-specific health-related quality of life (HRQOL) in a multi-site sample of youth with type 1 diabetes.

METHOD

One hundred and twenty-one youth and their primary caregivers completed measures of parent-child behaviors, child HRQOL, and participated in an observed family interaction task.

RESULTS

Diabetes-specific parent-child variables were associated significantly with both generic and diabetes-specific HRQOL above and beyond the contributions of demographic and generic parent-child variables, accounting for between 13% and 31% of the variance in HRQOL. Diabetes-specific family conflict and negative diabetes-specific family communication were associated with lower HRQOL. Collaborative parent involvement in diabetes care was associated with higher levels of HRQOL.

CONCLUSIONS

Interventions that target diabetes-specific family interactions will be beneficial to the quality of life of children with type 1 diabetes.

Parenting, autonomy and self-care of adolescents with Type 1 diabetes

BACKGROUND

During adolescence diabetes creates a juncture of very complex disease management demands with developmental needs, including the striving of adolescents for greater autonomy. Parents' concerns and fears about the teen's diabetes self-management abilities during this time can heighten parental attachment behaviour and affect the parents' ability to support autonomy development necessary for effective self-care. Maternal parenting processes may be especially important for those adolescents who have Type 1 diabetes because mothers are the primary caregivers.

PURPOSE

Based on attachment theory, the aim was to test a model of the influence of mother-adolescent developmental conflict, maternal separation anxiety and maternal inhibition of autonomy and relatedness on cognitive autonomy and self-care of adolescents with Type 1 diabetes.

METHOD

A total of 131 families with an adolescent, aged 11-15 years, contributed data annually across three waves. Mothers and adolescents completed paper-and-pencil measures and two interaction scenarios that were coded by trained staff from audio-tapes. The adolescent also completed a structured interview and questionnaire to assess self-care.

RESULTS

Maternal separation anxiety when adolescents were 11-15 years of age directly predicted cognitive autonomy at 1-year follow-up, and that cognitive autonomy was directly related to self-care 1 year later, but did not mediate between separation anxiety and self-care.

CONCLUSIONS

Future investigation of the influence of separation anxiety of parents on adolescent autonomy development is warranted, as well as the contribution of autonomy development to diabetes self-management behaviours of adolescents.

Finding the balance: adolescents with type 1 diabetes and their parents

INTRODUCTION

The purpose of this study was to describe the ways that parents and 11- to 15-year-old teens communicate and the recurrent themes and patterns of behavior that were revealed during brief interactions about issues related to diabetes management.

METHOD

A secondary qualitative analysis of data, based on a template for analysis developed from the literature, was completed on audiotaped interactions of 28 adolescents and their parents.

RESULTS

Themes identified were frustration, fear, normalizing, trusting, and discounting. Trusting the adolescent to manage diabetes was difficult for the parents and was associated with frustration, fear, and discounting communication.

DISCUSSION

Results support the need for clinicians to work with families to facilitate trust and positive parent-adolescent communication about diabetes management.

Quality of life in children with Type 1 diabetes: a comparison of general and diabetes-specific measures and support for a unitary diabetes quality-of-life construct

AIMS

To assess the factor structure of the Pediatric Quality of Life Inventory (PedsQL) Diabetes Module and to compare the PedsQL general and diabetes-specific quality of life (QOL) measures regarding psychometric properties and relations to relevant outcomes.

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.

Quality of life, psychological adjustment and metabolic control in youths with type 1 diabetes: a study with self- and parent-report questionnaires

OBJECTIVE

To evaluate self and parent reports on quality of life (QoL) and psychological adjustment of youths with type 1 diabetes, in comparison to a general paediatric population, and identify relationships between disease duration, metabolic control and psychological parameters.

RESEARCH DESIGN AND METHODS

Participants included 70 youths with type 1 diabetes and their parents. They were compared with 70 non-diabetic subjects. Data were analyzed in the whole group and in subgroups aged 6-10, 11-13 and 14-18 yr. All cases performed pediatric QoL, Child Behaviour Checklist, filled in by parents, and Youth Self-Report, filled in by youths. Data were compared with haemoglobin A1c (HbA1c) values and disease duration.

RESULTS

Self-reports showed a psychological adjustment of youths with type 1 diabetes similar to that of controls. Parent reports showed that parents of children with type 1 diabetes were more worried than those of controls (p < 0.01). Adolescents showed a worse QoL and more frequent psychological disturbances. In this group, for youth and parent reports, HbA1c levels correlated positively with psychological problems (p < 0.05) and negatively with QoL (p < 0.05). Only for parent reports, in the whole group and in subgroups aged 6-10 and 11-13 yr, disease duration correlated positively with psychological adjustment (p < 0.05).

CONCLUSIONS

Before adolescence, youths with type 1 diabetes showed only slight problems in psychological adjustment and QoL, with an association with disease duration reported by parents. In adolescence, both youths and their parents reported more emotional and behavioural problems, independent of disease duration. Better metabolic control and psychological well-being seemed directly related.

Qualidade de vida e aspectos socioeconômicos em diabéticos tipo 1

OBJETIVOS: Avaliar a qualidade de vida (QV) em diabéticos tipo 1 assistidos na Associação dos Diabéticos de Itabuna, BA (ASDITA), e verificar suas relações com as variáveis clínicas e sociodemográficas (escolaridade, renda familiar e ocupação). MÉTODOS: Foram estudados 34 pacientes (γ = 88%, ε = 5%; 53% mulheres, média de idade 20,4 ± 8,4 anos e média de tempo de diagnóstico 5,7 ± 4,9 anos), por meio de entrevista e antropometria (medidas de peso e altura). RESULTADOS: O perfil sociodemográfico da amostra revelou renda familiar per capita de 0,70 ± 0,56 salários mínimos, 53% possuíam o ensino fundamental, 64,7% eram estudantes. Em média, a qualidade de vida (QV) foi regular (58,8%). Não interferiram na QV: escolaridade, ocupação, etnia, índice de massa corpórea, número de aplicações diárias de insulina e perfil de monitoração da glicemia capilar. Associaram-se a pior QV: sexo feminino, ser adulto, tempo de diagnóstico maior ou igual a dez anos e baixa renda familiar. CONCLUSÕES: A QV destes pacientes foi inferior ao descrito na literatura, entretanto, estudos adicionais são necessários para comparações com diabéticos em condições socioeconômicas e culturais semelhantes às observadas nesta pesquisa.

A prospective study of quality of life in 77 type 1 diabetic patients 12 months after a hospital therapeutic educational programme

AIM

The aim of therapeutic education includes improvement of quality of life (QOL). However, the majority of studies are focused on biomedical or behavioural markers only. We performed a prospective study to assess QOL in adult type 1 diabetic patients for one year following a hospital educational programme.

METHODS

During this prospective single-centre study, QOL was assessed by the DQOL questionnaire in 77 consecutive patients at baseline and three, six and 12 months after a three-day educational programme.

RESULTS

The rate of response was 72.7% (n=55) at three months and 67.5% (n=52) at one year. The overall DQOL score improved at three months from 65.6+/-10.1 to 70.1+/-10.4 (P<0.001), and at one year from 65.1+/-10.4 to 68.5+/-11.7 (P=0.001). Patients exhibited greater satisfaction (66.3+/-15 versus 75.3+/-14.1, P<0.001), a diminished impact of diabetes (61.2+/-10 versus 63.4+/-9.6, P=0.016) as well as of anxiety related to diabetes (67.6+/-18.6 versus 73.6+/-16.2, P=0.009) at three months. This significant improvement was maintained at one year. Improvement in DQOL score at three months was positively correlated with a reduction in HbA(1c) (7.6+/-1.4% versus 7.8+/-1.4%, P=0.032), (r=-0.293, P<0.037). Patients with serious hypoglycaemia before the programme appeared to derive greater benefit from therapeutic education (OR: 9.88, 95% CI: 1.094-89.20).

CONCLUSION

QOL assessed by DQOL improved after therapeutic education and during the following year. The improvement in DQOL score at three months correlated with a reduction in HbA(1c) levels and appeared to particularly benefit to those who had severe hypoglycaemia before the programme.

Cultural adaptation and validation of the "Diabetes Quality of Life for Youths" measure of Ingersoll and Marrero into Brazilian culture

The aim of this study was to adapt the "Diabetes Quality of Life for Youths (DQOLY)" measure into Brazilian culture and to analyze its psychometric properties. The cross-cultural adaptation included the phases of translation, backtranslation, committee review, and pretesting. The adapted instrument was applied to 124 type 1 diabetes mellitus' adolescents. The reliability results showed adequate Cronbach's alpha coefficients (0.8695 for Satisfaction domain, 0.8658 for Impact, 0.8387 for Worries and 0.9333 for total), with the exclusion of 3 inconsistent items. The test-retests showed no significant difference between two instrument's applications in different periods (p>0.05). The validity was demonstrated by the strategies: content, convergent, factorial and discriminant. All subscales showed positive correlations between itselves (p<0.001) and with the adolescents' self-perception of their health status (p<0.001). The present study suggests that this version of the DQOLY is a reliable and valid measure for its use in Brazil.

Responsive parenting is associated with improved type 1 diabetes-related quality of life

BACKGROUND

Improved quality of life is an important treatment goal for children and adolescents with type 1 diabetes. While previous research supports a relationship between family environment and quality of life, little research has addressed the relationship of parenting style constructs to quality of life in children with chronic disease. The present investigation assesses the relationship of parent responsiveness and demandingness with diabetes-related quality of life among children and adolescents with type 1 diabetes.

METHODS

Baseline and 12-month follow-up self-report assessments were collected on a sample of 81 children with type 1 diabetes participating in an efficacy trial of a behavioural intervention to enhance adherence. The sample had a mean age of 13.3 years (SD=1.7) and duration of diabetes of 7.7 years (SD=3.7). Multiple regression analyses were conducted to determine the relationship of parent responsiveness and demandingness to diabetes-related quality of life at each time point.

RESULTS

After adjusting for demographic and diabetes characteristics, as well as diabetes-specific parent-child behaviours, parent responsiveness was significantly associated with baseline diabetes-related quality of life (beta=0.23; P=0.04). This relationship was sustained at 12-month follow-up (beta=0.22; P=0.04) after adjusting for baseline quality of life and treatment group assignment, suggesting that parent responsiveness is associated with improved quality of life.

CONCLUSIONS

Findings indicate the importance of a supportive and emotionally warm parenting style in promoting improved quality of life for children with type 1 diabetes. Appropriate parenting skills should be an element of diabetes family management health care.

Monitoring and discussing health-related quality of life in adolescents with type 1 diabetes improve psychosocial well-being: a randomized controlled trial

OBJECTIVE

To test the effects of monitoring and discussing of health-related quality of life (HRQoL) in adolescents with type 1 diabetes in a multicenter randomized controlled trial.

RESEARCH DESIGN AND METHODS

Four centers were randomly assigned to the HRQoL intervention (46 adolescents) or control (45 adolescents) group, with three regular visits scheduled within 12 months in both groups. In the HRQoL intervention group, HRQoL of adolescents was assessed using the Pediatric Quality of Life Inventory, and outcomes were discussed face-to-face during the consultation. The control group received care as usual. Mean differences between the groups at 12 months in physical and psychosocial well-being (Child Health Questionnaire [CHQ]-CF87/PF50, Diabetes-Specific Family Conflict Scale, and Center for Epidemiological Studies Scale for Depression), satisfaction with care (Patients' Evaluation of the Quality of Diabetes Care), and A1C were determined, controlling for baseline scores.

RESULTS

Mean scores on the CHQ subscales of psychosocial health (P < 0.001), behavior (P < 0.001), mental health (P < 0.001), and family activities (P < 0.001) improved in the HRQoL intervention group, except for adolescents with the highest A1C values. Adolescents in the HRQoL intervention group reported higher self-esteem (CHQ) at follow-up (P = 0.016), regardless of A1C, and were more satisfied with care (P = 0.009) than control subjects. No significant differences between the two groups over time were observed in A1C levels.

CONCLUSIONS

Periodic monitoring and discussion of HRQoL in adolescents with diabetes is appreciated and has positive effects on their psychosocial well-being, except for those in poorest control.

Predictors of diabetes-related quality of life after transitioning to the insulin pump

OBJECTIVE

To examine family and individual psychosocial, medical, and demographic factors associated with improved diabetes-related quality of life (QOL) after transitioning to the insulin pump among youth with type 1 diabetes.

METHOD

Fifty-three parent-child dyads completed questionnaires on four occasions prior to and following this medical regimen change, assessing QOL, family environment, depressive and anxiety symptoms, and medical and demographic information. Trajectories of change in QOL were analyzed using multilevel modeling.

RESULT

Psychosocial, medical, and demographic characteristics were associated with QOL prior to pump-start. Elements of children's QOL significantly improved after the transition, and improvement was predicted by psychosocial, medical, and demographic characteristics.

CONCLUSION

Results indicate that individual and contextual factors may play a role in QOL as children transition to the insulin pump. Findings may guide efforts to support families through this challenging time and potentially inform candidacy for transition to the pump.

Mediators of depressive symptoms in children with type 1 diabetes and their mothers

OBJECTIVE

To examine the relationships among maternal and child depressive symptoms and child and family psychosocial factors.

METHOD

Secondary analysis of baseline data for a coping skills intervention for school-age children (ages 8-12) with type 1 diabetes (T1D) and their mothers. Children and mothers completed measures of depressive symptoms, coping, quality of life, and family functioning.

RESULTS

There was a strong relationship between maternal and child depressive symptoms (r = .44, p < .001). Maternal depressive symptoms were negatively related to child quality of life, perceptions of coping, and family functioning. Impact of diabetes on quality of life, finding coping with diabetes upsetting, and family warmth mediated the relationship between maternal and child depressive symptoms.

CONCLUSIONS

Maternal depression may negatively affect child adjustment through its influence on quality of life, coping, and family functioning. Implications for interventions to improve psychosocial adjustment in children with T1D are discussed.

Short-term effects of coping skills training in school-age children with type 1 diabetes

OBJECTIVE

Little is known about the use of psychosocial interventions in children younger than adolescence with type 1 diabetes (T1D) and their parents. We report preliminary short-term outcomes of a randomized controlled trial of coping skills training (CST) compared with group education (GE) in school-aged children with T1D and their parents.

METHODS

One hundred and eleven children (range = 8-12 yr) with T1D for at least 6 months (3.71 +/- 2.91 yr) were randomized to CST (55.6% female (F); 81.5% white (W)) or GE (69.7% F; 90.9% W). Children and parents (n = 87) who completed the intervention, baseline, 1- and 3-month data are included. Children completed measures of self-efficacy, coping, and quality of life; parents completed measures of family functioning (adaptability and cohesion), diabetes-related conflict, parent depression, and parent coping. Metabolic control was assessed with glycosylated hemoglobin A1c. Mixed-model repeated measures anova was used to analyze the data.

RESULTS

CST and GE group composition was generally comparable. Children had good psychosocial adaptation and metabolic status. CST parents reported significantly more improvement in family adaptability compared with GE parents, and a trend was seen indicating that CST children showed greater improvement in life satisfaction than GE children. Effect sizes for this short-term follow-up period were small, but group participants were receptive to the intervention and reported positive gains.

CONCLUSIONS

In these preliminary results, CST and GE were more similar than different across multiple measure of psychosocial adaptation, although CST showed promising statistical trends for more adaptive family functioning and greater life satisfaction. Longer term follow-up is underway.

Prevalence and associations of psychological distress in young adults with Type 1 diabetes

AIMS

To determine the prevalence of psychological distress in young adults with Type 1 diabetes and to explore associated factors.

METHODS

Ninety-two participants with Type 1 diabetes (46 male, 46 female) attending a young adult clinic completed two psychological self-report assessments; the Centre for Epidemiological Studies-Depression Scale (CES-D) and Adult Self-Report Scale (ASR). The mean age was 21.6 +/- 2.8 years (sd) and mean duration of diabetes was 9.3 +/- 5.4 years. A questionnaire identified the method of insulin delivery, the frequency of blood glucose monitoring and hypoglycaemia requiring third-party assistance. HbA(1c) was measured.

RESULTS

Of the participants, 35.2% reported depressive symptoms (CES-D > or = 16), 23.1% indicating severe depressive symptoms (CES-D > or = 24), and 32.2, 40.4 and 35.5% of participants reported significant distress (ASR > or = 60) on the ASR total problem scales, ASR internalizing and ASR externalizing scores, respectively. Mean HbA(1c) levels were higher in participants with depressive symptoms compared with those with normal scores (CES-D > or = 16, HbA(1c)= 9.4% vs. CES-D < 16, HbA(1c)= 8.4%, P = 0.01). Factors associated with psychological distress included use of continuous subcutaneous insulin infusion (CSII) (P = 0.02) and increased frequency of hypoglycaemic episodes (P = 0.03). CSII users had higher CES-D (21.3 vs. 11.9, P = 0.001) and ASR-Total (59.7 vs. 53.0, P = 0.02) scores than non-CSII users.

CONCLUSIONS

Approximately one-third of young adults with Type 1 diabetes experience psychological distress, which is associated with poorer glycaemic control. Psychological distress was related to frequency of hypoglycaemic episodes and method of insulin administration, with significantly greater distress being observed in those using CSII. These findings support inclusion of a psychologist in the diabetes team.

The transition to young adulthood in youth with type 1 diabetes on intensive treatment

OBJECTIVE

We sought to examine prospectively patterns of clinical and psychosocial outcomes during the transition from adolescence to young adulthood in a cohort initiating intensive therapy after the Diabetes Control and Complications Trial.

RESEARCH DESIGN AND METHODS

We conducted a prospective, descriptive analysis of data from a randomized intervention study with 117 adolescents (45 males and 72 females, mean age at entry = 14.4 +/- 2.0 yr, mean diabetes duration at entry = 5.7 +/- 3.7 yr) recruited from a large pediatric diabetes clinic. Data were collected for each subject over periods of up to 5 yr at 6-month intervals using measures of depressive symptoms, quality of life, and metabolic control, with chart review for prevalence of diabetes complications.

RESULTS

Metabolic control worsens during adolescence but returns to early adolescent levels in young adulthood. The negative impact of diabetes on quality of life, disease-related worries, and life satisfaction did not change significantly with age. These results did not vary with treatment group or gender. Participants who showed high levels of depressive symptoms as adolescents were somewhat more likely to be depressed when older. Despite relatively long duration of diabetes, relatively few complications were observed in young adulthood.

CONCLUSIONS

These data suggest that youth who begin intensive treatment as adolescents generally have good metabolic and psychosocial outcomes as young adults. However, those who have high levels of depressive symptoms in adolescence tend to continue to have such symptoms in early adulthood.

SELF-CARE IN CHILDREN WITH TYPE 1 DIABETES

PURPOSE

To provide insight into mothers' perceptions of their children's development of diabetes-related capabilities and identify factors that influence these capabilities.

STUDY DESIGN AND METHOD

Mothers' perceptions of children's self-care practices were solicited using an 84-item fixed choice instrument authored by this investigator. Items that were based on the literature and results of a preliminary qualitative study solicited information regarding self-care practices, independence in management, parental involvement, dietary adherence, precision in skills, attitude about diabetes, and ability to manage abnormal blood glucose levels. Descriptive statistics were used to analyze the data.

RESULTS

Forty-six boys and 42 girls aged 6 to 18 years were represented by the 88 mothers in this study. According to the mothers, children demonstrated higher levels of self-care abilities, independence, precision, and ability to manage blood glucose levels as they aged. The mothers believed, however, that older children had more negative attitudes about diabetes than did younger children. Girls learned skills earlier and were more independent in diabetes-related self-care, yet they had more difficulty than boys in adhering to dietary requirements. Some findings indicated the children engaged in behaviors that were potentially life-threatening or at least deleterious to their future health.

CLINICAL IMPLICATIONS

Nurses can use this study to help encourage parents to stay involved with their children's self-care practices into the adolescent years. Providing opportunities for communication with others who have type 1 diabetes should be encouraged. Knowledge of age and gender differences can help establish realistic expectations for self-care.

Self-report and parent-report of physical and psychosocial well-being in Dutch adolescents with type 1 diabetes in relation to glycemic control

Background

To determine physical and psychosocial well-being of adolescents with type 1 diabetes by self-report and parent report and to explore associations with glycemic control and other clinical and socio-demographic characteristics.

Methods

Demographic, medical and psychosocial data were gathered from 4 participating outpatient pediatric diabetes clinics in the Netherlands. Ninety-one patients completed the Child Health Questionnaire-CF87 (CHQ-CF87), Centre for Epidemiological Studies scale for Depression (CES-D), and the DFCS (Diabetes-specific Family Conflict Scale). Parents completed the CHQ-PF50, CES-D and the DFCS.

Results

Mean age was 14.9 years (± 1.1), mean HbA_1c 8.8% (± 1.7; 6.2–15.0%). Compared to healthy controls, patients scored lower on CHQ subscales role functioning-physical and general health. Parents reported less favorable scores on the behavior subscale than adolescents. Fewer diabetes-specific family conflicts were associated with better psychosocial well-being and less depressive symptoms. Living in a one-parent family, being member of an ethnic minority and reporting lower well-being were all associated with higher HbA_1c values.

Conclusion

Overall, adolescents with type 1 diabetes report optimal well-being and parent report is in accordance with these findings. Poor glycemic control is common, with single-parent families and ethnic minorities particularly at risk. High HbA_1c values are related to lower social and family functioning.

Family influence on self-care, quality of life, and metabolic control in school-age children and adolescents with type 1 diabetes

This study explored the influence of family behaviors on self-care, quality of life (QoL), and metabolic control in school-age children and adolescents with type 1 diabetes. Ninety-nine participants were recruited in the midsouth from a health science center and an affiliated diabetes camp. Warm and caring family behaviors predicted self-care behaviors and aspects of QoL for the participants. African American school-age children and adolescents had more worries related to diabetes and had poorer metabolic control than Caucasians. Nursing implications included emphasizing open family communication and providing emotional support for diabetes management to promote developmentally appropriate levels of self-care and QoL.

Parent and health professional perspectives in the management of adolescents with diabetes: Development of assessment instruments for international studies

OBJECTIVE

Assessment of quality of life (QOL) in adolescents with diabetes requires patient, parent and health professional input. Psychometrically robust instruments to assess parent and professional perspectives are required.

RESEARCH DESIGN AND METHODS

Questionnaires concerning adolescent QOL were developed for completion by parents and health professionals. In an international study assessing QOL in 2,101 adolescents with diabetes (median age 14 years, range 10-18; from 17 countries including Europe, Japan and North America), parents and health professionals completed their respective questionnaires between March and August 1998.

RESULTS

Feasibility and acceptability of the new questionnaires were indicated by high questionnaire completion rates (adolescents 92%; parents 89%; health professionals 94%). Internal consistency was confirmed (Cronbach's alpha coefficients 0.80 parent; 0.86 health professional). Correlations of Diabetes Quality of Life Questionnaire for Youths (DQOLY) scores with parent and health professional global QOL ratings were generally low (r ranging from 0.12 to 0.36). Parent-rated burden decreased incrementally across adolescence, particularly for girls. Professional-rated burden followed a similar profile but only after age 15 years. Until then, burden was rated as uniformly high. Clinically relevant discrepancies in parent and professional burden scores were noted for one-parent families and families where adolescents had been referred for psychological help. In both cases, health professionals but not one-parent families perceived these as high burden situations. The clinical significance of this relates to the significantly poorer metabolic control recorded for adolescents in both situations.

CONCLUSIONS

Parent and health professional questionnaires were found to have adequate internal consistency, and convergent and discriminant validity in relation to key clinical and QOL outcomes. The questionnaires are brief, easy to administer and score. They may also enable comparisons across countries and languages to facilitate development of international health outcome parameters. The inclusion of the parent and health professional perspectives completes a comprehensive assessment of adolescent QOL relevant to diabetes.

Contemporary Australian outcomes in childhood and adolescent type 1 diabetes: 10 years post the Diabetes Control and Complications Trial

The reporting of the results of the Diabetes Control and Complications Trial in 1993 has led to a major reappraisal of management practices and outcomes in type 1 diabetes in children and adolescents. A considerable body of outcome data has been generated from Australia in this post-Diabetes Control and Complications Trial era relating to incidence, metabolic control, growth, hypoglycaemia, microvascular and macrovascular complications, cognition, behaviour and quality of life. These data are important in planning future management strategies and resource allocation and as a basis for future research.

The influence of ethnicity on health-related quality of life in diabetes mellitus: a population-based, multiethnic study

OBJECTIVES

The aims of this study were to evaluate the influence of ethnicity on health-related quality of life (HRQoL) in diabetic participants using both profile [the Short-Form 36 (SF-36)] and single-index (the SF-6D) instruments and to evaluate the usefulness of the SF-6D as a summary measure for the SF-36.

RESEARCH DESIGN AND METHODS

Using data from a cross-sectional, population-based survey of Chinese, Malay, and Indians in Singapore, we analyzed the influence of ethnicity and other variables on each SF-36 scale and SF-6D scores using linear regression models to adjust for the influence of known determinants of HRQoL.

RESULTS

Data from 309 diabetic respondents were analyzed. Compared with other ethnicities, Indians were most likely to report impaired HRQoL. The unadjusted influence of ethnicity on HRQoL exceeded the minimum clinically important difference (MCID) for all SF-36 scales (MCID: 5 points) and the SF-6D (MCID: 0.033 points). After adjusting for gender, age, and education, the influence of Chinese ethnicity exceeded the MCID for all SF-36 scales, except vitality (VT) and mental health (MH), as well as for the SF-6D. The influence of Malay ethnicity exceeded the MCID only for the SF-36 MH scale and the SF-6D. The influence of ethnicity on HRQoL persisted after adjusting further for other determinants of HRQoL. The SF-6D reflected the ethnic trends for some but not all SF-36 scales.

CONCLUSIONS

After adjusting for demographic, socioeconomic, and other factors known to influence HRQoL, ethnicity remained an important factor influencing HRQoL in this population-based multiethnic sample of diabetic Asians. Further studies to identify modifiable factors explaining the ethnic disparities in HRQoL among diabetic participants are needed. The SF-6D may be a useful summary measure for the SF-36.

Social support and diabetes management in childhood and adolescence: influence of parents and friends

This paper reviews the empirical research literature on the role of social support in children and adolescents with diabetes. Studies on the role of parental involvement in diabetes management suggest that premature withdrawal of parental involvement is associated with poor diabetes outcomes, whereas continued parental support and monitoring is associated with better outcomes among adolescents. Research on social support from friends suggests that friends can be a unique source of support that complements parents' involvement and improves adolescents' diabetes management.

A short form of the Diabetes Quality of Life for Youth questionnaire: exploratory and confirmatory analysis in a sample of 2,077 young people with type 1 diabetes mellitus

AIMS/HYPOTHESIS

The aim of this study was to test the construct validity of the Diabetes Quality of Life for Youth (DQOLY) questionnaire in a large representative sample of young people with type 1 diabetes mellitus.

METHODS

The 52-item DQOLY questionnaire was completed by 2,077 adolescent individuals (aged 10-18 years) with type 1 diabetes. Participants were recruited from 22 paediatric diabetes centres in 18 countries across Europe, Asia and North America. HbA(1c) levels were determined once and analysed centrally.

RESULTS

Exploratory factor analysis generated three possible measurement models of a revised questionnaire, two with four factors and one with six factors with all models indicating the presence of one satisfaction scale, but with many of the impact and worry scale items either double loading or not loading on any factors. Subsequent confirmatory analysis indicated that compared with the original DQOLY scales, the six-factor solution was the best-fitting model.

CONCLUSIONS/INTERPRETATION

The DQOLY factor structure does not show construct validity in a large, diverse representative sample of young people with type 1 diabetes. However, a revised (short-form) version of the DQOLY is proposed that has improved construct validity, adequate internal consistency, and more precise and hypothesised association with HbA(1c). It is anticipated that this shorter version will enhance the acceptability and clinical utility of the measure, making it more feasible to introduce as part of routine care.

Interventions to promote optimal health outcomes in children with Type 1 diabetes--are they effective?

The incidence of Type 1 diabetes is increasing worldwide, imposing enormous public health costs, as well as profoundly affecting individual quality of life. There is evidence that psychological problems are increased in children with diabetes and this morbidity is often associated with poor metabolic control. Specific risk factors for this dual morbidity are emerging from empirical studies. The next challenge is to identify effective interventions for use with children at risk for adverse mental and physical health outcomes. The intervention literature is reviewed. It is noted that most studies have used diabetes-specific, unstandardized interventions in groups of adolescents, with few interventions trialled with younger children. No study has targeted a specific psychological disorder such as behaviour problems or depression, both of which are known to be increased in children with diabetes and for which effective standardized interventions are available. Attention is drawn to methodological limitations in many of the studies conducted to date and suggestions made to reduce these in future interventions attempting to reduce the burden of illness in children with diabetes.

The psychologic context of pediatric diabetes

During the past few decades, there has been an explosion of behavioral science research on family management of pediatric diabetes. This article distills the major conclusions from that literature, emphasizing how primary care providers can apply these findings in clinical practice.

Insulin Pump Therapy and Health-Related Quality of Life in Children and Adolescents with Type 1 Diabetes

OBJECTIVES

To compare the health-related quality of life (HRQOL) of youths on injection regimens to those prescribed insulin pump therapy and examine factors related to HRQOL in youths with type 1 diabetes.

METHODS

An ethnically diverse group of youths (n = 160, ages 5-17 years) with type 1 diabetes and their caretakers completed family, parent, and child adjustment measures, as well as measures of generic- and disease-specific HRQOL. Metabolic control and regimen information were assessed through medical records.

RESULTS

HRQOL was unrelated to regimen prescription. Child, family, and parent adjustment variables were significantly related to HRQOL, whereas other demographic and clinical variables were relatively less important.

CONCLUSIONS

Present findings indicate that insulin pump therapy does not have negative implications for HRQOL. They also suggest that interventions aiming to improve HRQOL in this population should target child, parent, and family adjustment and not focus solely on disease-related outcomes.

Parents' perceptions of factors that affect successful diabetes management for their children

OBJECTIVE

To learn which factors parents perceive to be most influential in determining successful type 1 diabetes management.

METHODS

A 4-stage mixed qualitative-quantitative method that consists of a series of focus groups, a survey, and in-depth interviews was used to ensure that parents generated, prioritized, and explained their own ideas. In each stage, parents offered a new level of insight into their perception of how children achieve good metabolic control while living as normal a life as possible. The survey responses were divided into statistically different ranks, and the Kruskal-Wallis test was used to compare the results between subgroups.

RESULTS

A total of 149 parents participated in the formative qualitative phases, 799 families (66%) responded to the parent-generated survey, and 67 explanatory interviews were conducted. The families who responded to the survey had children of varied ages (mean: 11.9 years; SD: 4.44) and diabetes control (mean hemoglobin A1c: 8.22%; SD: 1.65); 84.1% of respondents were white, 12.3% were black, and 89% were privately insured. The 30 survey items were statistically discriminated into 8 ranks. The items cover a wide range of categories, including concrete ways of achieving better control, families' or children's traits that affect coping ability, actions of the health care team that support versus undermine families' efforts, and the availability of community supports. No clear pattern emerged regarding 1 category that parents perceived to matter most.

CONCLUSIONS

Clinicians can affect many of the factors that parents perceive to make a difference in whether they can successfully raise a resilient child in good diabetes control. Future research needs to determine whether health care teams that address the concerns that parents raised in this study are more effective in guiding children to cope well with diabetes, to incorporate healthier lifestyles, and ultimately to achieve better metabolic control.

Impact of improved glycemic control on quality of life in patients with diabetes

OBJECTIVE

To review the current literature that examines the effects of diabetes on the health-related quality of life (HRQOL).

METHODS

Three key diabetes-specific HRQOL survey instruments are described and reviewed. In addition, the findings in several recent studies that have assessed the effects of diabetes on HRQOL are discussed.

RESULTS

Although the medical benefits of improved glycemic control in diabetes have gained wide recognition, less attention has been paid to the effects of diabetes on HRQOL. Both generic and diabetes-oriented measures can be used to evaluate HRQOL. Numerous studies have shown that diabetes is associated with significant reductions in HRQOL. In particular, diabetes-related complications lead to diminished quality of life. Use of intensive diabetes treatment does not appear to reduce HRQOL, and alternative therapeutic strategies, as well as education and support, may benefit the quality of life in patients with diabetes.

CONCLUSION

Early and aggressive intensive therapy leading to improved glycemic control is likely to reduce the impact of diabetes on the HRQOL, by slowing the onset and progression of complications.

Quality of life profile--adolescent version: assessing the relationship of covariates to scale scores using structural equation modeling

This study investigates the effects of covariates on adolescent quality of life (QOL) using structural equation modeling (SEM). The Quality of Life Profile--Adolescent Version, a generic 54 item self-reported questionnaire, was administered to 363 adolescents aged between 10 and 18 years who were enrolled in 20 secondary schools within metropolitan Perth, the capital of Western Australia. Previous results based on a second-order SEM provided preliminary support for measuring adolescent QOL in terms of physical health, psychological, social, environment and opportunities for growth and development. The second-order model is further enhanced in this study by incorporating covariates age, presence of a chronic condition, amount of control and perception of health. The amount of control the adolescent perceived had a significant positive impact on QOL, whereas poorer reports of health had a negative impact. However, the presence of a chronic condition was found to have little effect on QOL, while the modest inverse relationship between age and QOL was not statistically significant.

Age, metabolic control and type of insulin regime influences health-related quality of life in children and adolescents with type 1 diabetes mellitus

The effects of illness and treatment of diabetes mellitus extend beyond medical outcomes. We therefore evaluated health-related quality of life (HRQOL) in children (aged 8-12 years) and adolescents (aged 13-16 years) with type 1 diabetes to compare their results with healthy peers and to identify HRQOL determinants. A total of 68 children and adolescents from a tertiary care clinic which specialises in the management of diabetes, completed the generic KINDL-R questionnaire. This instrument for children and adolescents has six dimensions and an additional module assessing condition-related HRQOL. Overall, the HRQOL was not different between patients with type 1 diabetes and healthy controls. In some areas, children and adolescents with diabetes reported a better HRQOL compared to healthy peers: adolescents reported better psychological well-being (P < 0.05) and children higher levels of well-being in the school domain (P < 0.05). In general, children reported a better HRQOL (P < 0.05) than adolescents with type 1 diabetes confirming age-related differences in HRQOL in the general population. Lower HbA1c (<8%) and intensified insulin therapy (>3 injections/day) were associated with a better HRQOL in different domains (P < 0.05). The subscale "chronic illness" showed a better HRQOL (P < 0.001) in children and adolescents with diabetes compared to age-matched controls with other chronic conditions.

CONCLUSION

Children and adolescents from a paediatric department specialising in diabetes management report good health-related quality of life. Younger age, good metabolic control and intensified insulin therapy are associated with a better health-related quality of life. Dimensions of health-related quality of life appear to play different roles at different ages, emphasising the importance of the multidimensional health-related quality of life concept and the value of age-appropriate self-reports.

Psychosocial and socioeconomic risk factors for premature death in young people with type 1 diabetes

OBJECTIVE

Mortality from acute diabetes-related events is greatly raised in young adults with type 1 diabetes. Psychosocial and socioeconomic risk factors are examined for deaths from acute events separately from deaths due to other causes.

RESEARCH DESIGN AND METHODS

This study had a nested case-control design. The cases were patients from the Diabetes UK cohort who died before age 40 years. Deaths were categorized as acute events or chronic conditions related to diabetes. Where possible, two matched control subjects were selected for each case. Data relating to psychosocial and socioeconomic factors and variables related to diabetes complications were extracted from the case notes. Risks of death were estimated by calculation of odds ratios (ORs).

RESULTS

Case notes were obtained for 98 case and 137 control subjects. Fifty-one deaths were attributed to acute causes, 34 to chronic conditions related to diabetes, and the remaining 13 were unrelated to diabetes. Living alone (OR 4.4), past drug abuse (5.7), and previous psychiatric referral (4.6) were all significantly associated with death from acute events but not death from chronic conditions. There was no association between deaths from acute events and nephropathy, hypertension, neuropathy, or retinopathy, although all of these were associated with deaths from chronic conditions.

CONCLUSIONS

The results indicate that psychosocial factors are powerful risk factors for mortality from acute events in patients with type 1 diabetes, although not for mortality from chronic conditions. The data enable the identification of a high-risk group suitable for targeting with preventive measures to reduce acute event mortality.

Assessment of Factors Affecting Quality of Life in Diabetic Patients in Iran

OBJECTIVE

Assess the pattern of relationships between personal-background characteristics and dimensions of quality of life (QOL) in diabetic patients.

DESIGN

Cross-sectional descriptive study.

SAMPLE

117 adults with type 2 diabetes (100 female, 17 male) randomly selected from outpatients referred to Sina hospital (Tabriz, Iran).

METHODS

Participants answered a three-part questionnaire including (1) sociodemographic and medical (diabetes-related) personal-background characteristics; (2) general health-related QOL instrument based on Swedish Health-Related QOL; (3) disease-specific instrument for diabetic patients. Nine QOL dimensions were covered: physical function, pain, daily activities, feelings, sleep, relationships with relatives, overall health, problems with diabetes, satisfaction with diabetes treatment methods. Data were analyzed with inferential statistics, correlation, and multi-stage stepwise regression.

RESULTS

Personal background characteristics (age, presence of medically educated people in family, whether patient was family breadwinner, unemployment, complications of diabetes) accounted for 27% of variance in the physical function dimension of QOL dimension. Other QOL dimensions (daily activities, overall health, sleep, satisfaction with diabetes treatment.) were also related to personal background characteristics.

CONCLUSIONS

Diabetic patients face great challenges in many dimensions of QOL. Nursing instructors and nursing educators in educational centers for diabetics can use the findings of this research to assess their patients more effectively.

The impact on health-related quality of life from non-steroidal anti-inflammatory drugs, methotrexate, or steroids in treatment for juvenile idiopathic arthritis

OBJECTIVE

To assess and compare the impact of medication treatments on health-related quality of life (HRQOL), family function, and medical status in children with juvenile idiopathic arthritis (JIA).

METHODS

Fifty-seven children diagnosed with JIA were assessed by a pediatric rheumatologist and placed into one of three treatment groups: (1) non-steroidal anti-inflammatory; (2) methotrexate; or (3) steroids via IV methylprednisolone. Questionnaires were administered at baseline and 4-month follow-up. The attending pediatric rheumatologist provided additional medical information.

RESULTS

Data document the impact of JIA on HRQOL, particularly on physical and pain domains. Steroid patients experienced improved HRQOL at follow-up relative to other groups, despite reporting more problems with side effects.

CONCLUSION

These results demonstrate positive benefits of steroids in treating JIA children, despite the greatest incidence of adverse side effects.

Self-care autonomy and outcomes of intensive therapy or usual care in youth with type 1 diabetes

OBJECTIVE

This article evaluated whether deviation from developmentally appropriate self-care autonomy moderated the effects of intensive therapy (IT) or usual care (UC) on glycosylated hemoglobin (HbA(1C)) in 142 youths with diabetes.

METHODS

Youths received an autonomy/maturity ratio (AMR) score at baseline that was a ratio of standardized scores on measures of self-care autonomy to standardized scores on measures of psychological maturity and were categorized by tertile split into low, moderate, and high AMR.

RESULTS

Higher baseline AMR was associated with higher baseline HbA(1C) for IT and UC. Baseline AMR scores predicted glycemic outcomes from UC; the high AMR tertile showed deteriorating glycemic control over time, whereas the low AMR tertile maintained better glycemic control. All three AMR groups derived equal glycemic benefit from IT.

CONCLUSION

Children with inordinate diabetes self-care autonomy may fare poorly in UC but these same children may realize less glycemic deterioration during IT.

Childhood precursors of adolescent outcomes in type 1 diabetes mellitus

Contemporary outcome measures of chronic illnesses such as type 1 diabetes mellitus are broader than those clinical outcomes traditionally assessed in therapeutic encounters. A holistic approach emphasises quality of life and emotional well-being as well as the achievement of optimal disease management. This paper reviews current knowledge about growth, metabolic control, diabetes complications, neurocognitive and psychological outcomes as well as health-related quality of life in childhood diabetes mellitus. It is suggested that the antecedents of adverse diabetes and psychological outcomes in adolescence lie in the years prior to adolescence. The model of care in childhood diabetes mellitus must be focussed on earlier screening and intervention if adverse outcomes are to be reduced.

A randomized trial of regular standardized telephone contact by a diabetes nurse educator in adolescents with poor diabetes control

OBJECTIVE

The aim of this study was to determine the effect of regular standardized telephone contact by a diabetes nurse educator (DNE) on metabolic control, treatment compliance, and quality of life in adolescents with poorly controlled type 1 diabetes.

METHODS

A single-blinded 6-month randomized controlled trial was used. Participants included 46 of 49 eligible adolescents (13-17 yr) with type 1 diabetes >1-yr duration and hemoglobin A1c (HbA1c) >8.5% for the previous 6 months. Subjects were randomly assigned to 6 months of standard diabetes management or standard care plus weekly telephone contact by a DNE. Telephone conversations included review of events in the adolescents' lives and diabetes education, but the primary focus was on blood glucose results and insulin-dose adjustments. HbA1c, compliance with glucose monitoring, quality of life [Diabetes Quality of Life Scale for Youth (DQOLY)], and family functioning [Family Environment Scale (FES)] were assessed at baseline, and at 3 and 6 months. Posthoc, HbA1c levels were assessed 6 months following study completion.

RESULTS

Six months of regular telephone contact by a DNE had no immediate effect on any of the outcome measures. However, posthoc 6 months, HbA1c levels decreased (1% change compared to baseline) in 6/21 of the study group and 0/18 of the control group, while HbA1c increased in 4/21 of study subjects compared to 8/18 of control subjects (p = 0.015).

CONCLUSIONS

In contrast to adult studies, regular telephone contact did not lead to immediate improvements in metabolic control in adolescents with poorly controlled type 1 diabetes. However, knowledge and skills gained during the intervention may have had a delayed beneficial effect in these high-risk adolescents.

Quality of life and diabetes knowledge of young persons with type 1 diabetes: Influence of treatment modalities and demographics

OBJECTIVE

The primary objective of this descriptive study was to assess the perception of quality of life and diabetes knowledge among young persons with type 1 diabetes. The secondary objectives were to examine the influence of treatment modality (continuous subcutaneous insulin infusion vs multiple daily injections) and demographics on quality of life and diabetes knowledge of these young persons and to determine the associations between the study variables.

RESEARCH DESIGN AND METHODS

Participants aged 9 to 17 years (n=103) completed the diabetes-specific measure of quality of life and a diabetes knowledge test. Parents of these young persons completed a history questionnaire. Descriptive statistics, independent t tests, and Pearson's correlations were used to analyze the data.

RESULTS

Overall, diabetes-specific measure of quality-of-life scores indicated good quality of life among the study population. Mean scores on the impact, worry, and satisfaction subscales did not indicate negative perceptions of the disease. Body mass index was significantly inversely correlated with the satisfaction scale ( r =-0.247, P =.023). Self-rated health was negatively correlated with the impact ( r =-0.221, P =.038) and worry scale ( r =-0.294, P =.004) and positively correlated with the satisfaction scale ( r =0.291, P =.004). Seventy-two percent correct responses were given on the diabetes knowledge test. Knowledge was significantly correlated to diabetes diagnosis age ( r =0.276, P =.009) and current age ( r =0.453, P =.0005). No significant differences were observed between participants using continuous subcutaneous insulin infusion vs multiple daily injections in regard to diabetes-specific measure of quality of life and diabetes knowledge test.

CONCLUSIONS

In our study, young persons with type 1 diabetes had a positive perception of their quality of life and above-average diabetes knowledge, which were influenced by several factors, such as self-rated health, body mass index, and age at diagnosis. Dietetics professionals should assess perceived quality of life and knowledge among young persons with type 1 diabetes because these factors can potentially influence disease management and treatment compliance.

Determinants of the quality of life of patients with congenital heart disease

OBJECTIVE

The improvement of the quality of life of chronically ill patients has become an important goal in treatment. However, it is seldom taken into account that many other factors, in addition to somatic factors, have an influence on the quality of life of patients. Using patients with congenital heart defects as an example, we examined the relative significance of biological factors, compared to psychological and social factors, for the various quality of life dimensions.

RESEARCH DESIGN AND METHODS

One hundred and eleven patients (aged 33+/-12 years) with different degrees of cardiac dysfunction were examined (NYHA 0: 2 I: 56, II: 38, III: 13, IV: 2). All patients for whom there was no contra-indication underwent a treadmill ergometry in order to determine their level of cardiopulmonary functioning (peak oxygen consumption: VO2max). All patients were asked to fill out questionnaires concerning their quality of life (WHOQOL-Bref), their cardiac complaints (Giessener Complaint Questionnaire GBB), their personality traits (Giessen Test GTS), and the social support they experience (Social Support Questionnaire SOZU-k22). The data were analyzed using a linear structural equation model (SEM).

RESULTS

In all aspects but the social domain, the HRQL of CgHD patients was significantly diminished compared to the normal population. The SEM proposed was valid, showing good indices of fit (chi2 = 1.18; p = 0.55; AGFI = 0.92). The level of cardiopulmonary functioning was most significant for the reporting of specific cardiac complaints (beta = -28) and for the physical component of the general HRQL (beta = 32), although the former was also influenced by a depressed disposition (beta = -0.20) and the extent of social support experienced (beta = 0.18). The objective findings, however, had virtually no individual significance for the psychological (beta = 0.09) and social domains (beta = -0.02). These HRQL domains are primarily influenced by depressive personality traits (beta= -26/-0.16) and the social support experienced (beta = 0.51/0.51).

CONCLUSIONS

The patient's organic dysfunction primarily determines illness-specific complaints but has little relevance for the psychological and social aspects of the HRQL. These aspects are predominantly determined by the patient's depressive disposition and by the experienced social support. A successful therapy should therefore take biological as well as psycho-social determinants of the quality of life into account.

Psychiatric morbidity and health outcome in Type 1 diabetes--perspectives from a prospective longitudinal study

AIMS

To describe psychiatric status and relationship to metabolic control in adolescents with Type 1 diabetes studied prospectively from diagnosis.

METHODS

Adolescents (n = 41) completed a self-report measure of psychiatric status 10 years after disease onset. Metabolic control information was recorded prospectively from diagnosis. The rate and type of psychiatric disorder were determined and the relationship between mental health status and metabolic control history examined.

RESULTS

Thirty-seven per cent of the adolescents met criteria for a DSM-IV psychiatric disorder, two to three times higher than community levels of psychiatric morbidity. Females were significantly more likely to receive a diagnoses (chi2 = 4.98, P < 0.05). Two thirds of participants had experienced at least one serious hypoglycaemic episode and one third had a history of chronic poor metabolic control. DSM-IV diagnoses were present in half of those with a history of chronic poor control, one third of the hypoglycaemia group and one quarter of well controlled participants. Adolescents with a current Mood (t = -2.83, P < 0. 01), Anxiety (t = -3.77, P = 0.001) or Behaviour (t = 2.56, P < 0.05) disorder and those with a history of poorly controlled diabetes (F (2,29) = 5.4, P = 0.01) had higher externalizing behaviour problem scores at diagnosis than those without current disorder.

CONCLUSIONS

Adolescents with Type 1 diabetes are at high risk for psychiatric disorder. Poorly controlled diabetes over the first 10 years of illness was associated with pre-existing behaviour problems at diagnosis and there was a trend for an association with current psychiatric status.
