Lung obstruction is characterized by blocked airflow, shortness of breath, and difficulty exhaling. The most common obstructive lung diseases are asthma and chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis. Approximately 15% of U.S. adults aged 40–79 have lung obstruction, with about one-third of those having moderate or worse obstruction. Smoking tobacco increases respiratory symptoms, lung function loss, and the rate of lung function decline. The benefits of smoking cessation are numerous for all adults and especially for those with lung obstruction.
A new NCHS report presents national estimates of cigarette smoking among adults with measured lung obstruction for the period 2007–2012.
Key Findings from this Report:
- During 2007–2012, 46.2% of adults aged 40–79 with lung obstruction currently smoked cigarettes. About 41% with mild and 55% with moderate or worse obstruction were current smokers.
- A similar percentage of men and women with lung obstruction, overall and at each level of severity, smoked cigarettes.
- A greater percentage of adults aged 40–59 with lung obstruction, overall and at each level of severity, smoked cigarettes than those aged 60–79.
- Cigarette smoking among adults with lung obstruction varied by race and Hispanic origin and by severity of obstruction.
- The percentage of adults with lung obstruction, overall and at each level of severity, who smoked cigarettes declined with increasing education.

NCHS released a report last week that presents 2013 U.S. final mortality data on deaths and death rates by demographic and medical characteristics. These data provide information on mortality patterns among U.S. residents by such variables as sex, race and ethnicity, and cause of death.
Information on mortality patterns is key to understanding changes in the health and well-being of the U.S. population. Life expectancy estimates, age-adjusted death rates by race and ethnicity and sex, 10 leading causes of death, and 10 leading causes of infant death were analyzed by comparing 2013 final data with 2012 final data. In 2013, a total of 2,596,993 resident deaths were registered in the United States.
Key Findings from the Report:
- Life expectancy for the U.S. population in 2013 was unchanged from 2012 at 78.8 years.
- The age-adjusted death rate of 731.9 per 100,000 standard population did not change significantly from 2012.
- The 10 leading causes in 2013 remained the same as in 2012, although unintentional injuries became the fourth leading cause, while stroke became the fifth. Age-adjusted death rates significantly decreased for 4 leading causes and increased for 2.
- The infant mortality rate in 2013 of 596.1 infant deaths per 100,000 live births did not change significantly from the rate in 2012. The 10 leading causes of infant death in 2013 remained the same as in 2012, although maternal complications became the third leading cause, while Sudden infant death syndrome became the fourth.
