Caring for a child with type 1 diabetes is a relentless, around-the-clock job. Blood glucose checks, insulin injections or pump management, carbohydrate counting, and the constant vigilance for dangerous highs and lows fall largely on parents, and the psychological weight of that responsibility can be enormous. A new cross-sectional study published in BMC Nursing by Fatma Yeşil of Yalova University and Emel Avçin of Adıyaman University adds a fresh piece to the picture of what makes this burden heavier or lighter: how well parents can find, understand, and use health information.
The researchers set out to examine the relationship between parental health literacy and caregiver burden among parents of children diagnosed with type 1 diabetes mellitus, an autoimmune condition in which the pancreas produces little or no insulin. Unlike type 2 diabetes, type 1 typically appears in childhood and demands continuous self-management, which in practice means family management. Every meal, every bout of exercise, every illness, and every night of sleep is punctuated by decisions that depend on interpreting numbers and acting on them correctly.
Health literacy, in the technical sense used by the researchers, refers to a person’s capacity to access, understand, evaluate, and apply health-related information. For parents of children with type 1 diabetes, this skill set is exercised constantly: reading nutrition labels, interpreting glucose meter readings and continuous glucose monitor trends, calculating insulin doses, recognizing the early signs of hypoglycemia and hyperglycemia, and communicating with a rotating cast of pediatric endocrinologists, nurses, and dietitians. The study’s central hypothesis was that parents with stronger health literacy would experience less caregiver burden, plausibly because they feel more competent and less anxious in managing the disease.
To test this, the team conducted a descriptive and cross-sectional study with 156 parents of children diagnosed with type 1 diabetes. Participants were recruited through convenience sampling between January and May 2025, using an online questionnaire distributed via social media platforms and online communication applications to reach eligible parents. The study was reported in accordance with the STROBE guidelines, the international standard for transparent reporting of observational research, and received ethics approval from the Yalova University Health Sciences Non-Interventional Clinical Research Ethics Committee.
Three instruments formed the backbone of the data collection. An information form captured demographic and clinical characteristics of the parents and children. The Health Literacy Scale–Short Form measured the parents’ ability to engage with health information. The Zarit Burden Interview, one of the most widely used instruments in caregiving research, quantified the subjective load that caregivers experience across domains such as physical health, emotional well-being, social life, and finances. Together, these tools allowed the researchers to test whether literacy and burden moved in opposite directions, as they predicted.
The sample sketched a familiar portrait of pediatric type 1 diabetes caregiving. Mothers made up 67.3 percent of the participants and fathers 32.7 percent, reflecting the persistent pattern in which mothers absorb the largest share of chronic disease management at home. Most of the children, 61.5 percent, were between 7 and 12 years old, an age span that spans the transition from supervised primary-school years to the early stirrings of adolescent independence. The average time since diagnosis was 3.96 years, with a standard deviation of 2.85, meaning the families had lived with the disease for a wide range of durations, from newly diagnosed to nearly a decade of daily management.
The headline numbers told a clear story. Parents scored a mean of 38.85 on the health literacy scale, with a standard deviation of 7.81, and a mean caregiver burden score of 32.83, with a standard deviation of 12.17. Statistical analysis revealed a negative and statistically significant correlation between the two measures: as parental health literacy rose, caregiver burden fell. The correlation coefficient was modest at r = -0.162, with a p-value of 0.013, meaning the relationship was unlikely to be a fluke of sampling but was also far from the whole explanation.
Before running their multiple linear regression, the researchers performed an outlier analysis to satisfy the assumptions of the model, a methodological step that helps prevent a handful of extreme respondents from distorting the results. The regression then painted a more nuanced picture than the simple correlation. Four variables emerged as significantly associated with caregiver burden: parent age, child age, health literacy, and household income status. Together, the model explained 25.9 percent of the total variance in burden scores, a figure that underscores just how multidimensional caregiver strain really is. Notably, the strongest single predictor was the child’s age, with a standardized beta coefficient of 0.437, suggesting that the developmental stage of the child weighs on parents more heavily than any other measured factor.
Why would a child’s age loom so large? The study’s data cannot answer that question directly, but the pattern is consistent with what clinicians observe in practice. School-age children face changing routines, unpredictable activity levels, and growing autonomy over food choices, all of which complicate glucose management. As children approach adolescence, the handover of responsibility from parent to child introduces its own anxieties, since developmental readiness to self-manage diabetes rarely arrives on a fixed schedule. The finding that income status also contributed to burden aligns with the well-documented financial strain of diabetes supplies, technology, and dietary demands, which families with fewer resources feel most acutely.
The authors are careful about the limits of their results. The association between health literacy and burden, while statistically significant, was modest in magnitude, and the cross-sectional design means the study captures a single moment in time rather than tracking how literacy and burden evolve together. Convenience sampling through online channels may also have reached parents who are more digitally connected and potentially more health-literate than the broader population of caregivers. The regression model, for all its significant predictors, still left roughly three quarters of the variance in burden unexplained, a reminder that factors outside this analysis, from marital dynamics to social support to the child’s glycemic control, likely shape the experience of caregiving as well.
Even so, the findings carry a practical message for pediatric nursing and diabetes care teams. If a parent’s ability to access, understand, evaluate, and apply health information is linked to how heavily the caregiving load sits on their shoulders, then education is not just about better glucose numbers; it may also be a form of psychological support. The authors suggest that future studies should evaluate whether nurse-led education and counseling programs targeting these health literacy skills are associated with improved caregiver outcomes. In a condition where families perform the bulk of medical care at home, every investment in making parents more confident readers of their child’s disease may pay a double dividend: sharper daily management and a lighter emotional load for the people carrying it.
