Abstract

Background:

Globally, there is increasing evidence of resistance to government-led public health interventions in areas such as vaccination, climate change mitigation, sexual and reproductive healthcare, and the implementation of non-pharmaceutical infection control measures. One potential explanation for this could be the documented global rise in populist attitudes, characterised by distrust of scientific, government and other perceived 'elites.' While the effect of such attitudes on engagement with COVID-19-related interventions has been extensively considered and researched, their association with the receipt of other public health interventions is currently underexplored.

Methods:

To understand how populist-aligned views might influence the receipt of public health interventions addressing areas other than COVID-19, we systematically reviewed quantitative research published across thirteen bibliographic databases and relevant websites between 2008 and 2024. All studies were set in member countries of the Organisation for Economic Co-operation and Development (OECD).

Results:

Across 30 included studies, the vast majority of which were cross-sectional, we found evidence that populist-aligned attitudes have a negative impact on the receipt of public health interventions including vaccinations, sexual and reproductive health care and preventive health care. We also found preliminary evidence of the negative role of populist-aligned attitudes on the receipt of disease screening related to HIV/AIDS and adherence to non-pharmaceutical interventions during times of public health emergency, such as the 2009 H1N1 pandemic.

Conclusions:

Although providing limited evidence of causality, the findings from this review suggest the need for future policy in many OECD countries to focus on trust-building between the public and political, scientific, and medical establishments. They also indicate the need for mitigation strategies to overcome the potentially negative impact of populist-style hostility towards out-groups on attitudes related to pressing public health issues such as abortion and family planning, for example by drawing on empathy-centred approaches.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

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, controlled...

Analysis of Population Pharmacokinetic Data

Analysis of Population Pharmacokinetic Data

Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

Steps in Outbreak Investigation

Steps in Outbreak Investigation

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Levels of Health Promotion and Illness Prevention

Levels of Health Promotion and Illness Prevention

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...

Investigation of Disease Outbreaks

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
