Pulmonary Function and Cardiovascular Risk Factor: Results (2)

Pulmonary Function and Cardiovascular Risk Factor: Results (2)Relationships between cigarette smoking habits and FEV/Ht2 were similar in all four sex and race groups and statistically significant except among black men. Ex-smokers had slightly higher mean levels of FEV/ Ht2 than nonsmokers, and means declined with increasing numbers of pack years of exposure for current smokers (Fig 2). Because the normal effect of aging on FEV^t2 in nonsmokers was controlled, when present, by the adjustment described above, this association is attributable to the effect of smoking. FEV/Ht2 declined with increasing number of cigarettes currently smoked per day (Tables 2 and 3). More detailed information about pulmonary (unction and cigarette smoking habits and exposures has been reported. ventolin 100 mcg
In women, but not in men, the prevalence of shortness of breath was highest in those with the lowest lung (unction and generally decreased with increasing lung function (Fig 3). The prevalence of shortness of breath increased with increasing body mass index (BMI), but its relationship with lung (unction remained statistically significant after adjustment for BMI in women.
