Author Information

Primary Institution: Connecticut Department of Public Health

Hypothesis

Trends in incidence rates for tobacco-related cancers may vary geographically due to socioeconomic status and tobacco control programs.

Conclusion

Lung and oral cavity-pharynx cancer rates among whites aged 15 to 54 years declined more in California than in other areas, likely due to comprehensive tobacco control efforts.

Supporting Evidence

  • California had the earliest statewide comprehensive tobacco control program starting in 1989.
  • Significant declines in lung cancer rates were observed in California compared to other states.
  • Bladder cancer trends differed from lung and oral cavity-pharynx cancers, indicating other influencing factors.

Takeaway

This study looked at how cancer rates related to smoking changed in different parts of the US over time, finding that places with strong anti-smoking laws saw bigger drops in cancer rates.

Methodology

The study analyzed age-adjusted incidence rates for lung, oral cavity-pharynx, and bladder cancers from 1992 to 2004 in 11 SEER areas.

Potential Biases

Potential biases may arise from the ecological nature of the study and reliance on historical data.

Limitations

The study's findings may not fully account for other factors influencing cancer rates, and only a limited number of geographic areas were analyzed.

Participant Demographics

The study focused on adults aged 15 to 54 years, with data analyzed separately for whites and blacks.
