Health Literacy01:21

Health Literacy

4.1K
Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

147
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Hazard Ratio01:12

Hazard Ratio

155
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
For example, in a clinical trial...

Preventive Healthcare Services01:30

Preventive Healthcare Services

1.0K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Pre-Procedural Guidelines for Assessing Blood Pressure01:10

Pre-Procedural Guidelines for Assessing Blood Pressure

595
Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the...

Levels of Health Promotion and Illness Prevention01:26

Levels of Health Promotion and Illness Prevention

12.7K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Area of Science:

  • Public Health
  • Health Communication
  • HIV Prevention

Background:

  • Pre-exposure prophylaxis (PrEP) is a proven HIV prevention method.
  • PrEP uptake remains limited and inequitable, potentially due to information accessibility.
  • Analyzing PrEP information readability is key to improving education and communication.

Purpose of the Study:

  • To examine the readability of web-based PrEP information.
  • To identify factors influencing PrEP information readability across different sources and formats.

Main Methods:

  • Systematic identification of web-based PrEP documents via search engines and Twitter API.
  • Categorization of documents by source, format, modality, and audience.
  • Assessment of readability using four indices and comparison across categories.

Main Results:

  • 463 documents were analyzed; overall readability was at a 10.2-grade level.
  • This exceeds the recommended ninth-grade level for public health information.
  • Only brochures met the recommended readability standard.

Conclusions:

  • Complex language in web-based PrEP information may impede uptake.
  • Improving readability is essential for informed decision-making and national HIV prevention.
  • Aligning information with health communication guidelines will enhance access and support PrEP goals.
