摘要

Background

Research indicates that about 40% of all cancer cases within the European Union (EU) are preventable. Public awareness of modifiable risk factors is essential for informed health-related decision-making. Systematic assessments of public awareness are crucial for identifying awareness gaps and guiding targeted public health interventions. This study aimed to examine awareness of cancer risk factors among the Swedish general public, and to examine the attitude towards lifestyle changes for cancer prevention.

Methods

This cross-sectional study used a pre-existing data set with a randomly selected sample of 1520 participants (18–84 years old) recruited from a Swedish online survey panel in April 2024. Statistical analyses utilized post-stratification weights to make the results representative for the general Swedish population. Pearson’s χ2-test and weighted adjusted logistic regression were used to test for associations between demographic characteristics, believing that changed lifestyle habits could reduce one’s cancer risk, and awareness of 20 established risk factors for cancer.

Results

A majority (63.6%) of the respondents believed that one’s cancer risk could be reduced through changed lifestyle habits. Most were aware of smoking (97.1%), sun exposure (92.4%), hereditary factors (91.0%), sunbeds (90.2%), and air pollution (90.2%), while fewer were aware of alcohol (64.9%), obesity (61.6%), overweight (58.1%), and processed meat (53.3%) as cancer risk factors. A minority of the responders were aware of low levels of physical activity (48.1%), red meat (38.9%), low intake of fruit and vegetables (32.9%), low intake of whole grains (23.7%) and not breast-feeding one’s child (9.3%) as risk factors. For most risk factors, the awareness was significantly higher among college/university educated respondents.

Conclusions

Beside significant awareness gaps among the Swedish general public regarding several established cancer risk factors, this study found an educational gradient, illuminating important differences in cancer prevention awareness. Achieving meaningful improvements in cancer prevention awareness requires coordinated system-level and policy-level actions to reduce the educational gradient and ensure equitable access to information. This could in turn increase people’s ability to make well-informed decisions regarding their lifestyle habits and preventive measures.
