48−90歳の男女3528名を対象に、パイプ・葉巻喫煙の影響を横断的研究で調査。パイプ・葉巻喫煙者では非喫煙者に比べ尿中コチニン値が上昇し、パイプ喫煙年数はFEV1低下、葉巻喫煙年数はFEV1/FVC比低下と関連した。パイプ・葉巻喫煙者は、紙巻きタバコ喫煙歴がなくても非喫煙者より気道閉塞オッズ比の増加を認めた。

Abstract

Background: Cigarette smoking is the major cause of chronic obstructive pulmonary disease, but studies on the contribution of other smoking techniques are sparse.

Objective: To determine whether pipe and cigar smoking was associated with elevated cotinine levels, decrements in lung function, and increased odds of airflow obstruction.

Design: Cross-sectional study.

Setting: Population-based sample from 6 U.S. communities.

Participants: Men and women aged 48 to 90 years without clinical cardiovascular disease at enrollment who were part of MESA (Multi-Ethnic Study of Atherosclerosis).

Measurements: The MESA Lung Study measured spirometry according to American Thoracic Society guidelines and urine cotinine levels by immunoassay on a subsample of MESA. Pipe-years and cigar-years were calculated as years from self-reported age of starting to age of quitting (or to current age in current users) multiplied by pipe-bowls or cigars per day.

Results: Of 3528 participants, 9% reported pipe smoking (median, 15 pipe-years), 11% reported cigar smoking (median, 6 cigar-years), and 52% reported cigarette smoking (median, 18 pack-years). Self-reported current pipe and cigar smokers had elevated urine cotinine levels compared with never-smokers. Pipe-years were associated with decrements in FEV1, and cigar-years were associated with decrements in the FEV1-FVC ratio. Participants who smoked pipes or cigars had increased odds of airflow obstruction whether they had also smoked cigarettes (odds ratio, 3.43 [95% CI, 1.75 to 6.71]; P< 0.001) or not (odds ratio, 2.31 [CI, 1.04 to 5.11]; P= 0.039) compared with participants with no smoking history.

Limitation: Cross-sectional design.

Conclusion: Pipe and cigar smoking increased urine cotinine levels and was associated with decreased lung function and increased odds of airflow obstruction, even in participants who had never smoked cigarettes.
