Background: Poor literacy can impact achieving optimal health outcomes. The aim of this project was to assess the readability of parent information leaflets (PILs).
Methods: A single-centre study using paediatric PILs. Five readability tests were applied (Gunning Fog Index (GFI), Simple Measure of Gobbledygook (SMOG), Flesch Kincaid Grade Level (FKGL), Coleman-Liau Index (CLI) and Automated Readability Index (ARI)). Results were compared to standards and by subtype.
Results: A total of 109 PILs were obtained; mean (±SD) number of characters was 14,365 (±12,055), total words 3066 (±2541), number of sentences 153 (±112), lexical density 49 (±3), number of characters per word 4.7 (±0.1), number of syllables per word 1.6 (±0.1) and number of words per sentence 19.1 (±2.5). The Flesch reading ease score was 51.1 (±5.6), equating to reading age 16-17 years. The mean PIL readability scores were GFI (12.18), SMOG (11.94), FKGL (10.89), CLI (10.08) and ARI (10.1). There were 0 (0%) PILs classed as easy (score <6), 21 (19%) mid-range (6-10) and 88 (81%) were difficult (>10). They were significantly above the recommended reading age (p < 0.0001) and commercial studies were least accessible (p < 0.01).
Conclusion: Existing PILs are above the national reading level. Researchers should use readability tools to ensure that they are accessible.
Impact: Poor literacy is a barrier to accessing research and achieving good health outcomes. Current parent information leaflets are pitched far higher than the national reading age. This study provides data to demonstrate the reading age of a large portfolio of research studies. This work raises awareness of literacy as a barrier to research participation and provides tips on how to improve the readability of patient information leaflets to guide investigators.

Objective: The effects of opioid use disorder (OUD) are devastating and wide-ranging. Although the information in the >43,000 manuscripts on OUD are searchable, gaining a comprehensive grasp of this information is out of reach to most persons. We present a pilot study to use published data on OUD, repurpose it for rapid comprehension and distribution to the world.

Prenatal stress has been associated with poor cognitive outcomes in offspring, but the evidence about the role of exact timing of exposure is mixed and that about causal mechanisms is limited. Using the Avon Longitudinal Study of Parents and Children, this study (N = 4,525) explored the role of inflammation in the association between timing of prenatal-stressor exposure and cognitive functioning in middle childhood (ages 9-11 years). Prenatal-stressor exposure was measured at two timepoints (until 18 weeks gestation and from then until 8 weeks postpartum).

Background: School-based cognitive behavioral therapy (CBT) programs delivered by teachers are effective in preventing anxiety among children. Internet-based CBT has emerged as an efficient method for delivering such interventions. Our previous research demonstrated the feasibility of the e-learning version of Journey of the Brave in reducing anxiety among Japanese elementary school students in a home-based learning environment.

Introduction: The MOVE-AIR study was designed to explore the moderating role of movement behaviours on the association between air pollutants and health outcomes in Portuguese children. Secondarily, it aims to characterise the settings (both indoor and outdoor) where children are exposed to air pollutants and to co-create solutions with participants to mitigate the exposure to air pollutants in children's daily life. This study aims to describe the MOVE-AIR study protocol in detail.

Objective: This study evaluates and compares the readability of pediatric otolaryngology patient education materials generated by ChatGPT4o and those retrieved from Google searches. The goal is to determine whether artificial intelligence (AI)-generated content improves accessibility compared to institutionally affiliated online resources.
