Trends in Lung Cancer Incidence Rates, Oklahoma 2005–2010

Purpose Lung cancer is the second most frequently diagnosed cancer among men and women in the United States. With cigarette smoking causing the majority of cases, patterns in lung cancer are often monitored to understand the impact of anti-tobacco efforts. The purpose of this research was to investigate trends in lung cancer incidence rates for the period 2005–2010 in Oklahoma. Methods Data on Oklahoma’s incident cases of lung cancer (2005–2010) were obtained from the Centers for Disease Control and Prevention WONDER system. Annual percent change (APC) was calculated by linear regression to characterize trends in lung cancer incidence rates over time for the overall population, by gender, by age group, and by age group within gender. Rates were considered to increase or decrease if the p-value for trend was <0.05. Results From 2005 through 2010, lung cancer incidence rates declined from 81.96 to 68.19 per 100,000 population, with an APC of -3.58% (p-value: 0.0220). When subgroups were examined, declines were observed among all males (APC: -4.25%; p-value: 0.0270), males <65 years (APC: -5.32%; p-value: 0.0008), females <65 years (APC: -4.85%; p-value: 0.0044), and persons aged 55–64 years (APC: -6.38%; p-value: 0.0017). Conclusions Declines in lung cancer incidence rates occurred during 2005–2010 among the overall population and within select demographic groups in Oklahoma. Although trends were stable for several demographic groups, rates of lung cancer incidence were lower in 2010 compared to 2005. Continued evidence-based tobacco control efforts are needed to ensure further reductions in lung cancer incidence rates in the state of Oklahoma.Yeshttp://www.plosone.org/static/editorial#pee

Clinical and Individual Factors Associated with Smoking Quit Attempts among Adults with COPD: Do Factors Vary with Regard to Race?

Only half of adults with chronic obstructive pulmonary disease (COPD) report a smoking quit attempt in the past year. Adults with COPD have frequent encounters with the healthcare system that are opportunities for health behavior interventions that support quit attempts. The purpose of this research was to examine individual- and clinical-level factors associated with smoking quit attempts in adults with COPD. Cross-sectional data were from the 2011 Behavioral Risk Factor Surveillance System. Race-stratified, weighted logistic regression examined factors associated with quit attempt among current smokers with COPD. Overall, quit attempt was reported by 65% (95% confidence interval (CI): 61.9, 67.5) of adults and was more likely among blacks than whites (p < 0.0001). Among whites with COPD quit attempt was associated with: Female gender (adjusted odds ratio (AOR) = 1.3; CI: 1.0, 1.7), exercise (AOR = 2.0; CI: 1.5, 2.5), and medications for COPD (AOR = 1.6; CI: 1.3, 2.2). Among black adults with COPD quit attempt was associated with: Having a partner (AOR = 4.5; CI: 1.3, 15.0), exercise (AOR = 3.7; CI: 1.6, 8.7), spirometry (AOR = 9.5; CI: 3.2, 28.7), and having a personal doctor (AOR = 6.4; CI: 1.8, 22.5). Individual and clinical-factors associated with quit attempt varied by race. These findings suggest an impact of the healthcare system that supports quit attempts in blacks but not whites with COPD.</p

Influenza vaccination in adults with chronic obstructive pulmonary disease: the impact of a diagnostic breathing test on vaccination rates.

INTRODUCTION: Influenza vaccination rates are low in adults with chronic obstructive pulmonary disease (COPD). A diagnostic breathing test in adults with COPD may increase vaccination rates; however, research has not demonstrated this relationship. The purpose of this research was to determine if adults with COPD diagnosed by a breathing test were more likely to have had an influenza vaccination during the past 12 months when compared to those with COPD diagnosed without a breathing test. METHODS: This was a cross-sectional study using data from the 2011 Behavioral Risk Factor Surveillance System. Logistic regression examined the relationship between influenza vaccination among adults with COPD diagnosed with a breathing test (n = 13,201) compared to those diagnosed without a breathing test (n = 3,108), after controlling for all potential confounders. RESULTS: Overall, 49% of respondents with COPD received an influenza vaccination within the past 12 months and 78% reported their COPD was diagnosed by a breathing test. The prevalence of influenza vaccination in the past 12 months was greater in those with COPD diagnosed by a breathing test (53%) compared to those diagnosed without a breathing test (36%). In adjusted analysis, adults with COPD who had a breathing test were 31% (confidence interval 1.1, 1.6) more likely to have received an influenza vaccination in the past 12 months compared to those without a breathing test. DISCUSSION: A diagnostic breathing test for COPD was associated with increased likelihood of having had an influenza vaccination in the past 12 months. This may be an indicator of the relationship between knowledge of lung function and the need for preventative care, a sign of quality healthcare, or good health-seeking behaviors in patients with COPD. This research is the first to use a nationally representative sample to suggest that spirometry diagnosis of COPD may increase rates of influenza vaccination
