Short-Term Health Outcomes of Cooking Ultrafine Particle Exposure

This study is looking at how short-term exposure to ultrafine particles (UFPs) and gases from cooking might affect your breathing and thinking abilities. Healthy adults will spend two separate 6-hour sessions in a special room. During one session, you'll breathe clean air. During the other, research staff will cook potatoes and beef to create cooking fumes. Researchers will measure your lung function using a peak expiratory flow (PEF) test and your cognitive (thinking) skills using tests like the Hopkins Verbal Learning Test-Revised. The goal is to understand the immediate effects of common indoor cooking pollution. This study is currently unclear on its status and plans to enroll 15 participants.

Study design
This is an interventional study with 15 healthy adult participants. It uses a randomized crossover design, meaning each participant experiences both the clean air and cooking exposure conditions.
What's involved
You would participate in two consecutive study sessions, each lasting approximately 6 hours. During these sessions, you will have your lung function and cognitive performance assessed multiple times.
Compensation
Not stated in the trial record.
Follow-up
Your lung function and cognitive performance will be measured at baseline and at approximately 1, 2, 3, and 5 hours after the start of each session.

  • Change in Hopkins Verbal Learning Test-Revised (HVLT-R) Total Recall ScoreMeasured at baseline and at approximately 1, 2, 3, and 5 hours after session start on both study days

    Cognitive performance related to verbal memory will be assessed using the Hopkins Verbal Learning Test-Revised (HVLT-R). The primary metric will be the change in HVLT-R Total Recall Score between exposure and control conditions, calculated from repeated assessments to evaluate short-term cognitive effects of ultrafine particle exposure.

  • Change in Peak Expiratory Flow (PEF)Measured at baseline and at approximately 1, 2, 3, and 5 hours after session start on both study days

    Peak Expiratory Flow (PEF) will be measured using a handheld peak flow meter to assess short-term changes in lung function following exposure to cooking-generated ultrafine particles compared with the clean-air control day. Changes are evaluated within subjects using repeated measurements across both conditions.

  • Change in WAIS Symbol Search Raw ScoreMeasured at baseline and at approximately 1, 2, 3, and 5 hours after session start on both study days

    Cognitive performance related to processing speed and visual attention will be assessed using the Symbol Search subtest of the Wechsler Adult Intelligence Scale (WAIS). The primary metric will be the change in WAIS Symbol Search raw score between exposure and control conditions, calculated from repeated assessments to evaluate short-term cognitive effects of ultrafine particle exposure.
