Summary
Socioeconomic status significantly impacts cancer mortality correlations across Argentine provinces. Adjusting for this factor (NBI) altered many observed geographical cancer death rate relationships.
Area of Science:
- Epidemiology
- Public Health
- Cancer Research
Background:
- Cancer mortality rates exhibit geographical variations.
- Understanding factors influencing these variations is crucial for public health interventions.
Purpose of the Study:
- To analyze age-standardized cancer mortality rates in Argentine provinces.
- To investigate correlations between geographical cancer mortality distributions.
- To assess the influence of socioeconomic status (NBI) on these correlations.
Main Methods:
- Calculated age-standardized cancer mortality rates (1980-1986).
- Analyzed correlations between geographical distributions of cancer mortality rates.
- Adjusted for socioeconomic status (NBI) using multivariate analysis and stratification.
- Examined intersex correlations for various cancer sites.
Main Results:
- Positive intersex correlations found for colon, liver, pancreas, esophagus, stomach, gallbladder, and bladder cancers.
- Negative correlations with NBI for breast, ovary, colon, pancreas, and male bladder cancers.
- Positive correlations with NBI for cervix and uterine cancers.
- After NBI adjustment, only lung, bladder, larynx, and male pancreas cancer correlations remained significant.
- Stratified analysis revealed NBI modifies many correlation indexes.
Conclusions:
- Socioeconomic level (NBI) is a significant confounder in cancer mortality correlations.
- NBI effectively modifies geographical associations of cancer mortality rates.
- Public health strategies must consider socioeconomic factors when addressing cancer disparities.
