Risk assessment for developing type 1 diabetes: intentions of behavioural changes prior to risk notification

Anxiety and Risk Perception in Parents of Children Identified by Population Screening as High Risk for Type 1 Diabetes

OBJECTIVE

To assess anxiety and risk perception among parents whose children screened positive for islet autoantibodies, indicating elevated risk for type 1 diabetes (T1D).

RESEARCH DESIGN AND METHODS

The Autoimmunity Screening for Kids (ASK) study identified 319 children age 1 to 17 years at risk for T1D via screening for islet autoantibodies; 280 children with confirmed islet autoantibodies and their caregivers enrolled in a follow-up education and monitoring program to prevent diabetic ketoacidosis at diagnosis. Parents completed questionnaires at each monitoring visit, including a 6-item version of the State Anxiety Inventory (SAI), to assess anxiety about their child developing T1D, and a single question to assess risk perception.

RESULTS

At the first ASK follow-up monitoring visit, mean parental anxiety was elevated above the clinical cutoff of 40 (SAI 46.1 ± 11.2). At the second follow-up monitoring visit (i.e., visit 2), mean anxiety remained elevated but started to trend down. Approximately half (48.9%) of parents reported their child was at increased risk for T1D at the initial follow-up monitoring visit (visit 1). Parents of children with more than one islet autoantibody and a first-degree relative with T1D were more likely to report their child was at increased risk.

CONCLUSIONS

Most parents of autoantibody-positive children have high anxiety about their child developing T1D. Information about the risk of developing T1D is difficult to convey, as evidenced by the wide range of risk perception reported in this sample.

Impact of Anti-Diabetic Medications on Quality of Life in Persons with Type 2 Diabetes Mellitus

INTRODUCTION

Type 2 diabetes mellitus (T2DM) has been found to be associated with poor quality of life (QOL). The aim of this study was to measure QOL in T2DM patients and examine if the patients' socio demographic, diabetes-related clinical characteristics and insulin usage are associated with better quality of life.

MATERIALS AND METHODS

This clinic based cross-sectional study analyzed data from outpatients with T2DM attending a referral clinic between January and June 2016. Association between Diabetes Attitudes, Wishes and Needs (DAWN) QOL and few demographic, socioeconomic, clinical and biochemical predictors were examined using multivariate logistic regression model. A total of 518 patients completed the interview.

RESULTS

The HbA1c level of insulin ± oral anti-diabetic (OAD) cohort was significantly lower (7.89 ± 1.98) than the OAD cohort (8.79 ± 1.96), P < 0.001. Compared to their counterparts in the OAD cohort, patients on insulin were older with longer duration of diabetes mellitus. Co-morbid confounders like obesity, hypoglycemia, and blood pressure control or socio demographic confounders like income, education were almost similar in both the cohorts. The incidence of hypertension, coronary artery disease (CAD) and statin usage was significantly higher in the insulin cohort. The overall composite DAWN QOL scores of the insulin ± OAD cohort (25.42 ± 4.35) was marginally higher than that of the OAD cohort (23.62 ± 5.06) (P = 0.067). Analog insulin users were also found to have significantly higher composite DAWN QOL scores compared to human insulin users (25.77 ± 5.73 vs.24.13 ± 4.88, P = 0.037).

CONCLUSIONS

The insulin cohort, despite being older and having longer duration of diabetes, had significantly higher diet compliance score, and enhanced QOL owing to better diabetes-related knowledge and treatment adherence characteristics than non-insulin users. Questionnaires-based evaluation of QOL can provide better understanding of the patient's experience of the illness, self-care, psychological and emotional functioning, and choice of therapeutic modality enhancing the quality of care.

Parental monitoring for type 1 diabetes in genetically at-risk young children: The TEDDY study

OBJECTIVE

We examined parental diabetes monitoring behaviors in a cohort of children at increased genetic risk for type 1 diabetes. We hypothesized that being informed of a positive islet autoantibody (IA) would increase monitoring behaviors.

RESEARCH DESIGN AND METHODS

The Environmental Determinants of Diabetes in the Young (TEDDY) study follows 8676 children with high-risk human leucocyte antigen-DQ genotypes from birth to age 15, including general population (GP) children and those with a first-degree relative (FDR) with diabetes. Data on parental monitoring behaviors were solicited yearly. Serum samples were tested for IA and parents were informed of child results. We examined parental monitoring behaviors during the first 7 years of TEDDY.

RESULTS

In IA- children, the most common monitoring behavior was participating in TEDDY study tasks; up to 49.8% and 44.2% of mothers and fathers, respectively, reported this. Among FDRs, 7%-10% reported watching for diabetes symptoms and 7%-9% reported monitoring the child's glucose, for mothers and fathers, respectively. After IA+ notification, all monitoring behaviors significantly increased in GP parents; only glucose monitoring increased in FDR parents and these behaviors continued for up to 4 years. FDR status, accurate diabetes risk perception, and anxiety were associated with glucose monitoring in IA+ and IA- cohorts.

CONCLUSIONS

Many parents view TEDDY participation as a way to monitor for type 1 diabetes, a benefit of enrollment in a longitudinal study with no prevention offered. IA+ notification increases short- and long-term monitoring behaviors. For IA- and IA+ children, FDR parents engage in glucose monitoring, even when not instructed to do so.

Parental Estimation of Their Child's Increased Type 1 Diabetes Risk During the First 2 Years of Participation in an International Observational Study: Results From the TEDDY study

This study assessed mothers' and fathers' perception of their child's risk of getting type 1 diabetes (T1D) during the first 2 years of their participation in The Environmental Determinants of Diabetes in the Young (TEDDY) study. TEDDY parents were informed of their child's increased genetic risk for T1D at study inception. Parent perception of the child's risk was assessed at 3, 6, 15, and 27 months of age. In families with no history of T1D, underestimation of the child's T1D risk was common in mothers (>38%) and more so in fathers (>50%). The analyses indicated that parental education, country of residence, family history of T1D, household crowding, ethnic minority status, and beliefs that the child's T1D risk can be reduced were factors associated with parental risk perception accuracy. Even when given extensive information about their child's T1D risk, parents often fail to accurately grasp the information provided. This is particularly true for fathers, families from low socioeconomic backgrounds, and those with no family history of T1D. It is important to develop improved tools for risk communication tailored to individual family needs.

Assessment of psychosocial variables by parents of youth with type 1 diabetes mellitus

PURPOSE

To evaluate the impact of type 1 diabetes (T1D) on family functioning and child-rearing practices from parents' point of view, to assess parents' health-related quality of life and to explore the relations between psychosocial variables and diabetes care outcomes in youth with diabetes.

METHODS

This research was part of the cross-sectional multicenter Brazilian Type 1 Diabetes Study, conducted between December 2008 and December 2010 in 28 public clinics of 20 cities across four Brazilian geographical regions. Psychosocial questions were addressed to 1,079 parents of patients with T1D through an interview (89.3% mothers, 52.5% Caucasians, 38.6 ± 7.6 years old). Overall, 72.5% of the families were from low or very low socioeconomic levels. Parents were also submitted to health-related quality of life instruments (EQ-5D+EQ-VAS). Clinical data from the last medical appointment were collected by a physician using standardized chart review forms. The demographic, educational and socioeconomic profiles were also obtained and HbA1c levels registered.

RESULTS

Discomfort and anxiety/depression were the main complaints in EQ-5D, and were significantly more frequent in mothers (37.3% and 53.4%, respectively) than in fathers (25.7% and 32.7%, respectively). The mother was the only parent involved in diabetes care in 50.5% of the cases. The majority of parents (78.5%) mentioned changes in family functioning after the diagnosis, although they neither treated their diabetic children differently from the others (76.3%), nor set prohibitions (69.1%) due to diabetes. The majority was worried about diabetes complications (96.4%) and felt overwhelmed by diabetes care (62.8%). Parents report of overwhelming was significantly associated with anxiety/depression, as measured by the EQ-5D questionnaire. Less than half of the patients had already slept over, and the permission to do it increased as a function of children's age. Nearly half of the parents (52%) admitted to experiencing difficulties in setting limits for their children/adolescents. HbA1c levels in patients from this group (9.7 ± 2.5%) were significantly higher than those of children/adolescents whose parents reported no difficulties towards limit-setting (8.8 ± 2.1%). Parents whose children/adolescents reported the occurrence of hypoglycemic episodes in the last month complained significantly more about anxiety/depression (55.1%) than parents from patients who did not report it (45.7%). Also a significantly greater proportion of parents whose children/adolescents had been hospitalized due to hyperglycemia reported anxiety /depression (58.7%) than those whose children/adolescents had not been hospitalized (49.8%).

CONCLUSIONS

After the diagnosis of T1D, the lifestyle of all family members changes, what interferes with their quality of life. Mothers are still the primary caregivers for children/adolescents with diabetes. Difficulty to set limits for children/adolescents may be a risk for poor metabolic control. The study demonstrates the importance of family context in the adjustment of young patients to T1D. The specific needs of T1D patients and their impact on a family routine must be considered for future improvement on therapy elements and strategies.

Psychological impact of screening and prediction in type 1 diabetes

Screening programs designed to identify persons at risk for type 1 diabetes via genetic and antibody testing are controversial because they typically target children, provide only a crude estimate of type 1 diabetes risk, and offer no means of preventing the disease. For this reason, genetic and antibody testing for type 1 diabetes risk is usually limited to carefully conducted research studies. The psychological impact of such screening programs include cognitive, emotional, and behavioral sequelae; the available literature has focused primarily on parents, and usually mothers, since the target of screening is usually infants or young children. Diabetes risk is a difficult construct to effectively communicate. Many individuals fail to accurately understand risk; inaccurate risk perceptions may increase over time and have been associated with early study withdrawal. Simply asking study participants if they understand the risk information provided is insufficient. Anxiety and worry are common reactions to learning that you or a loved one is at increased risk for type 1 diabetes. For most people, anxiety and worry dissipate with time but some individuals may be particularly vulnerable to prolonged anxiety or depression. Although there is no known means to prevent type 1 diabetes in at-risk individuals, families often report increased surveillance of those at risk and behavior changes to prevent the disease, potentially threatening the internal validity of the study.

The Environmental Determinants of Diabetes in the Young (TEDDY) study: study design

The primary objective of this multicenter, multinational, epidemiological study is the identification of infectious agents, dietary factors, or other environmental exposures that are associated with increased risk of autoimmunity and type 1 diabetes mellitus (T1DM). Factors affecting specific phenotypic manifestations such as early age of onset or rate of progression or with protection from the development of T1DM will also be identified. The Environmental Determinants of Diabetes in the Young (TEDDY) is an observational cohort study in which newborns who are younger than 4 months and have high-risk human leukocyte antigen alleles in the general population or are first-degree relatives (FDRs) of patients affected with T1DM will be enrolled. Six clinical centers in the USA and Europe will screen 361,588 newborns, of which it is anticipated that 17,804 will be eligible for enrollment with just over 7,800 followed. Recruitment will occur over 5 yr, with children being followed to the age of 15 yr. Identification of such factors will lead to a better understanding of disease pathogenesis and result in new strategies to prevent, delay, or reverse T1DM.

Maternal efforts to prevent type 1 diabetes in at-risk children

OBJECTIVE

The aim of this study was to assess maternal diabetes prevention efforts aimed at children identified as at risk through newborn genetic screening.

RESEARCH DESIGN AND METHODS

A total of 192 mothers of children identified as at risk for type 1 diabetes through newborn genetic screening were administered a structured interview 3.6 +/- 0.8 years after risk notification. The interview assessed possible diabetes prevention behaviors across six domains: health surveillance, diet, physical activity, illness prevention, medications, and stress reduction. A mother's cognitive (diabetes risk perception and perceived control), affective (anxiety), and coping responses to the child's at-risk status were assessed.

RESULTS

A total of 67% of mothers reported one or more diabetes prevention behaviors. Monitoring behaviors (e.g., watching for signs of diabetes and checking blood glucose) were the most common, reported in 59%, followed by modifications in the child's diet in 34% and physical activity in 14%. Potentially harmful prevention behaviors (e.g., limiting contact with other children, delaying immunizations, and giving medications including insulin) were rare. Mothers who engaged in diabetes prevention behaviors reported higher diabetes risk perception, greater anxiety, and more use of certain coping styles. Infants of these mothers were more likely to have a first-degree relative with diabetes.

CONCLUSIONS

In the absence of known methods of preventing type 1 diabetes, most mothers of at-risk children report diabetes prevention behaviors. Such behaviors must be more carefully assessed to ensure accurate interpretation of data obtained from natural history studies and prevention trials.

Psychological impact of childhood islet autoantibody testing in families participating in the BABYDIAB study

AIMS

To determine anxiety in parents of children undergoing testing for islet autoantibodies.

SUBJECTS AND METHODS

Children of parents with Type 1 diabetes (T1DM) were tested at birth, age 9 months, 2 years and 5 years for islet autoantibodies. Families were informed about islet autoantibody status in the child after each visit. The psychological impact of islet autoantibody testing was assessed in parents before and after the 5 years visit. Anxiety was measured using a subscale of the State-Trait-Anxiety Inventory (STAI) and structured single-item questions. Four hundred and sixty-three parents were evaluated before blood drawing and 317 parents at notification of islet autoantibody status.

RESULTS

Before blood withdrawal, anxiety was increased in mothers and in particular in mothers of islet autoantibody-positive offspring compared with a normative control group. At notification of islet antibody status, anxiety significantly decreased in parents of islet autoantibody-negative offspring, and increased in parents of islet autoantibody-positive offspring. Blood withdrawal was considered a burden for parents and offspring (15% and 48%, respectively). Most parents from islet autoantibody-negative and -positive offspring wished to know the diabetes risk of their child (95% and 100%, respectively) and were glad to be informed about their child's islet antibody status (97% and 87%).

CONCLUSIONS

Overall, islet autoantibody testing in early childhood reduces anxiety in T1DM families. The increased anxiety associated with islet autoantibody-positive status suggests, however, that testing should be performed in centres which can provide accurate risk information and counselling if required.
