Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Measuring the effect of poor indoor air quality on COPD

    High concentrations of fine particulate pollution — the type associated with secondhand smoke and, in developing countries, indoor cooking and heating fires — are linked to poorer health, according to researchers in Scotland. reports that the researchers measured levels of fine, airborne particles — pollutants smaller than 2.5 microns in diameter (PM2.5) — in the homes of 148 Scottish patients with chronic obstructive pulmonary disease (COPD). Over the course of a week, they took air samples every 5 minutes. Outdoor levels were also sampled.

    And, the results.

    • Concentrations of particulate pollution in the homes frequently exceeded standards for outdoor air.
    • High levels were recorded in the homes of people with COPD, with the highest levels being 4 times the 24-hour maximum recommended by the US Environmental Protection Agency (EPA).
    • Environmental tobacco smoke was a significant component of the pollutants.
    • Nearly 40% of the subjects were current smokers.
    • 17% of non-smokers lived in “smoking environments” where others smoked in their homes.
    • Both smokers and non-smokers were negatively affected by increased PM2.5, as measured by significant differences in St George’s Respiratory Questionnaire (SGRQ) symptom scores — designed to measure the extent of impaired health in people with asthma or COPD.
    • Analysis of the effect of indoor air quality on smokers vs non-smokers revealed that smokers suffered greater adverse effects that nonsmokers.

    The bottom line?
    The researchers recommend to do more studies — surprise.

    I think it makes sense to lower air pollution in the home now. Speak with your healthcare provider. More information from the EPA on residential air cleaning is discussed here.
