Summary
Colorectal cancer (CRC) screening adherence varies by race, income, and access to care. Culturally tailored programs are recommended to improve screening rates for all populations.
Area of Science:
- Public Health
- Cancer Epidemiology
- Health Disparities
Background:
- Colorectal cancer (CRC) is a leading cause of cancer mortality in the US.
- Screening adherence remains a challenge, influenced by sociodemographic factors.
- This study investigates disparities in CRC screening adherence.
Purpose of the Study:
- To examine factors associated with adherence to colorectal cancer (CRC) screening methods.
- To identify disparities in CRC screening based on sociodemographic characteristics.
Main Methods:
- Analysis of the 2022-2023 Behavioral Risk Factor Surveillance System (BRFSS) dataset.
- Inclusion of participants aged 45-75 years.
- Multivariate logistic regression to assess associations between sociodemographic factors and adherence to CRC screening tests (colonoscopy, sigmoidoscopy, stool testing, virtual colonoscopy).
Main Results:
- Over 239 million adults were analyzed.
- Colonoscopy adherence was higher among Black non-Hispanic adults, those with primary care provider (PCP) access, and urban residents.
- Stool test adherence was higher among Hispanic adults, those with PCP access, divorced individuals, and those with less education.
Conclusions:
- Racial/ethnic background, socioeconomic status, and marital status significantly influence adherence to specific CRC screening modalities.
- Targeted, culturally aware interventions are needed to overcome barriers and improve CRC screening rates.
- Addressing disparities can enhance public health outcomes in CRC prevention.

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:26Principles of Disease Surveillance
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...
01:18Factors Affecting Illness
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness, disability,...

01:12Relative Risk
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...
01:26Levels 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...
