While increasing evidence suggests that ozone (O) exposure is associated with adverse birth outcomes, only one study has focused on its impact on the premature rupture of membranes (PROM). Therefore, we thus examined the effect of O on PROM in Xinxiang, China, using an over-dispersed Poisson generalized additive model. Several confounding factors, including meteorological factors, temporal trends, the day of the week, and public holidays, were considered in the model. We identified a total of 3255 instances of PROM from January 1, 2015 to December 31, 2017, and there was a significant association between the daily maximum 8-h mean concentrations (O) and PROM. Each 10 μg/m increase in the 3-day average concentration (lag02) of O corresponded to an increment in PROM of 5.42% (95%
1.45-9.39%). Although the results of the stratified analyses were insignificant, a few trending results were observed: stronger associations between O and PROM would occur in women with advanced age (≥35) or during the warm season than those in younger women (<35) or during the cool season. Our study indicates that O exposure is an important risk factor of PROM and should be considered in its prevention and control in the study area.

Many studies have indicated the detrimental effect of ambient ozone to respiratory health in different countries. The levels of ozone in Hanoi, Vietnam are frequently above the WHO guideline but very ...
The ground-level ozone (O) concentration in the urban regions of China has become an increasingly noticeable environmental problem in recent years. Many epidemiological studies have reported the assoc...
Ambient air pollution has been associated with acute cardiovascular events; however, the underlying mechanisms remain incompletely understood. We aimed to examine the impacts of ambient air pollutants...
Tropospheric (ground level) ozone (O) is a secondary pollutant, emerging from other pollutants in the sunshine. Exposure to O correlates with higher pulmonary and cardiovascular mortality and affects...
Studies have examined the variation in mortality risk associated with ambient ozone. We conducted an international cooperation study for investigating the non-linear ozone-mortality association accoun...
The purpose of the study is to better understand the mechanisms of lung injury from ozone exposure. Subjects will participate in two exposure sessions: filtered air and 0.2 ppm ozone. Subj...
This observational study recruits healthy individuals who have been routinely taking high amount (at least 3 g/wk) of dietary eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), an...
The purpose of this research study is to learn more about the effects of 0.12 ppm ozone exposure on humans. We know from other studies that exposure to levels of ozone that are seen on ba...
This is a randomized controlled human exposure crossover study. Investigators aim to investigate the acute health effects of ozone exposure in healthy young adults.
The purpose of this protocol is to assess whether epigenetic factors in healthy individuals make a person more or less responsive to lung inflammation following ozone exposures.
A shift in the balance between production and destruction of STRATOSPHERIC OZONE that results in a decline of the amount of OZONE in the lower stratosphere.
Ozone in the Earth's stratosphere. It is produced continuously by the action of solar ULTRAVIOLET RAYS on oxygen in the stratosphere. The stratospheric ozone (especially at the ozone layer) blocks much of the solar UV radiation of wavelengths of 320 nanometers or less from being transmitted to lower ATMOSPHERE of the Earth.
Spontaneous tearing of the membranes surrounding the FETUS any time before the onset of OBSTETRIC LABOR. Preterm PROM is membrane rupture before 37 weeks of GESTATION.
Acute suppurative inflammation of the inner eye with necrosis of the sclera (and sometimes the cornea) and extension of the inflammation into the orbit. Pain may be severe and the globe may rupture. In endophthalmitis the globe does not rupture.
A type of cardiac arrhythmia with premature contractions of the HEART VENTRICLES. It is characterized by the premature QRS complex on ECG that is of abnormal shape and great duration (generally >129 msec). It is the most common form of all cardiac arrhythmias. Premature ventricular complexes have no clinical significance except in concurrence with heart diseases.
