The association between personal care products and lung function

Area of Science:

• Environmental Health
• Respiratory Medicine
• Toxicology

Background:

• Chemical exposures are recognized as significant factors influencing respiratory health.
• Personal care products (PCPs) can contain components that may be inhaled, potentially affecting the lungs.

Purpose of the Study:

• To investigate the association between the frequency of personal care product use and lung function.
• To determine if specific categories of PCPs are linked to adverse respiratory outcomes.

Main Methods:

• Utilized data from the Canadian Health Measures Survey, including questionnaires and spirometry.
• Assessed lung function parameters: 1-second forced expiratory volume (FEV1) and forced vital capacity (FVC) as percentages of predicted values.
• Examined the relationship between FEV1/FVC and the usage frequency of various PCPs (eye makeup, fragrances, hair products, lipstick, scented body products).

Main Results:

• A total of 5,016 participants reported using at least one PCP.
• Increased use of hairspray products was linked to a ~2% reduction in both FEV1 and FVC in men and women.
• Among women, all PCP categories showed a significant decrease in lung function, with scented body products showing the largest decrease in FVC (~4%).

Conclusions:

• Findings suggest a potential adverse association between personal care product usage and lung function.
• Further research is recommended to confirm these findings and explore the underlying mechanisms.
