the effect of prenatal tvoc exposure on birth and infantile weight: the mothers and children’s environmental health study - household air cleaner
Volatile organic compounds (VOCs)
May limit growth before and after childbirth.
However, the effects of prenatal VOCs exposure on postpartum growth have not been adequately studied.
Therefore, we investigated the relationship between total volatile organic exposure (TVOCs)
During pregnancy and its effect on postpartum growth.
Methods from 2006 to 2008, a total of 383 pregnant participants signed up.
We used the questionnaire to investigate the maternal traits.
In the middle and late stages of pregnancy, personal air samples of TVOCs were obtained.
After delivery, these mothers selected 360 single-born newborns and followed up after delivery.
Up data were collected at 6, 12, 24 and 36 months, as well as human body measurement factors including body weight.
Statistical analysis uses multiple general linear and mixed models.
Results The average concentration of TVOCs exposed to prenatal exposure was 284.
The formaldehyde content was 81 μg/m3. 6u2009μg/m3.
Prenatal TVOC exposure significantly reduces newborn birth weight (β=−45. 89, P=0. 04).
The adjusted average weight is high-TVOC group (ue2f675th)
In contrast, in the lowExposure group (
