Cancer Prevention02:59

Cancer 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.

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
Preventive Healthcare Services01:30

Preventive Healthcare Services

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:
Cancer Survival Analysis01:21

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Summary
This summary is machine-generated.

Hong Kong's colorectal cancer screening program increased participation and reduced socioeconomic disparities over nine years. However, overall screening rates remain low, necessitating targeted efforts to improve health equity.

Area of Science:

  • Public Health
  • Cancer Epidemiology
  • Health Services Research

Background:

  • Colorectal cancer (CRC) is a leading cause of cancer death globally, with early detection crucial for improved survival.
  • Hong Kong implemented an organized colorectal cancer screening program (CRCSP) in 2016 to address this.
  • Assessing the CRCSP's impact on screening participation equity across socioeconomic groups is vital.

Purpose of the Study:

  • To evaluate the association between the CRCSP and health equity in cancer screening participation.
  • To analyze trends in fecal testing and colonoscopy uptake among different socioeconomic strata over a 9-year period.

Main Methods:

  • Analysis of individual-level data from 14,602 adults (aged 50-75) via three territory-wide population surveys (2014-2022).
  • Assessment of screening disparities using concentration curves and indices by socioeconomic status and income.
  • Application of generalized logistic regression models to identify factors associated with screening participation.

    • Main Results:

    • Colorectal cancer screening participation increased: fecal testing from 19.88% to 27.15%, colonoscopy from 17.65% to 27.28%.
    • Socioeconomic disparities in screening uptake narrowed significantly, indicated by declining concentration indices.
    • Screening participation was positively associated with older age, higher education, income, and socioeconomic status.

    Conclusions:

    • The CRCSP led to increased colorectal cancer screening participation and reduced socioeconomic disparities in Hong Kong.
    • Despite improvements, overall screening uptake remains low, with persistent disparities in younger, lower-income, and public housing resident groups.
    • Targeted interventions are essential to enhance screening participation and achieve greater health equity in CRC prevention.
