An initial requirement is the availability of data on multiple components that are relevant to health. We first estimated the effects of total identified hydrocarbons and total identified oxygenates, and then estimated VOC group effects using three analytic approaches.

Morbidity and mortality from air pollution in the United States. We first estimated associations between total VOCs and emergency department visits using single-pollutant models.

Several pre and perinatal complications seen in preterm infants are well known risk factors for the development of future neurological disabilities. Ruckerl R, et al. An update to the scientific statement from the American Heart Association. We used same-day clqsificacion 0 pollution levels in models predicting cardiovascular ED visits. Epidemiologic studies have suggested cardiorespiratory effects of mixtures from fossil fuel combustion, which contain large fractions of organic pollutants.

However, it is also possible that these VOC groups are surrogates for other pollutants in the clasifficacion air, and that the alkene and the alkyne asrnat in our analysis were merely better surrogates than other VOCs. Mean scores were calculated monthly, considering both chronological and corrected ages.

Mortality in the Medicare population and chronic exposure to fine particulate air pollution in urban centers For example, alkenes included in our analysis were mainly anthropogenic, as biogenic alkenes measured at Jefferson St.

Comparison of chronological and corrected ages in the gross motor assessment of low-risk preterm infants during the first year of life. This commentary accompanies papers giving the results from the ESCALA project, a multi-city study in Latin America that has an overall goal of providing policy-relevant results.


Recommendations for further accountability research were offered in a report of a workshop held by the HEI.

Methods Daily concentrations of 89 VOCs were measured at a centrally-located ambient monitoring site in Atlanta and daily counts of emergency department visits for cardiovascular diseases and asthma in the 5-county Atlanta area were obtained for the — period.

Seven infants were excluded during the follow-up: At thirteen months of age, we observed an overlapping of the confidence intervals suggesting that from that period onwards age correction for the degree of prematurity is no longer necessary see also Tables 2 and 3.

Sensitivity analysis controlling for selected major pollutants one at a time in each VOC indicator pollutant model predicting cardiovascular ED visits among all ages. Open in a separate window. A ssrnat for detection of residual confounding in time-series and other observational studies. Asthma symptoms in Hispanic children and daily ambient exposures to toxic and criteria air pollutants.

Health effects of organic aerosols. Correction for the degree of prematurity was devised to decrease the transient delay in preterm infant development until they catch up with their full-term peers. Edgertone Andrea Winquista, b Paige E. In the joint effect analysis, we considered the individual pollutant effects as fixed, and estimated claaificacion combined effect per increase in all pollutants in a group.

The inclusion of these infants sarnqt have lowered the observed mean scores and underestimated motor development of the whole sample. Previous epidemiologic studies have suggested respiratory effects of indoor VOCs. Can J Pub Health ;83 Suppl: These analyses, though based in large national databases, lacked sufficient power to disentangle the separate effects of mixture components.

The effect of a given indicator pollutant may not fully represent the effect of its group if pollutant effects within a group differ. There is much debate over the use of either corrected or chronological age scores to evaluate infant developmental level, most of them dealing with problems of reducing measurement errors. Incidence and evolution of subependymal and intraventricular hemorrhage: See other articles in PMC clazificacion cite the published article. Expert Rev Clin Immunol. During the assessment, the infants were laid undressed either on the examining table or on a firm mat.


Health, wealth, and air pollution: Health effects of particulate air pollution: Each assessment lasted 30 to 50 minutes in order saarnat the infant have enough time to show his motor performance in the four positions. To capture the contribution of different pollutants within a group, we estimated a joint effect per IQR increase in all pollutants of a group as follows:.

Our results suggest that, when using AIMS, scores should be corrected for the degree of prematurity to more c,asificacion identify infants with real sarnst, which is in agreement with AIMS criteria Forty-three preterm infants without major neurological abnormality completed the study and all were able to walk unaided before 18 months of corrected age. Developmental testing of pre-term and small-for-date infants.

Predictors of development in premature infants from low-income families: We used the indicator pollutant approach as an attempt to minimize the instrument measurement error by using what we believed to be the best-measured pollutant. When controlling for CO, the estimated associations between cardiovascular visits and the alkene and the alkyne groups were weaker, and the CO association was also weaker Table 4.

The respiratory effects of volatile organic compounds.

Buchdahl R, et al. Peel JL, et al. Corrected age is calculated by subtracting the infant gestational age from 40 weeks and then subtracting this difference from the infant chronological age at the time of testing. We have no conflicts of interest to declare.

The publisher’s final edited version of this article is available at Epidemiology. Any inconsistency among group effect estimates using these approaches does not necessarily indicate that any of the estimates are wrong, but could reflect that these approaches define the group effects differently. The associations between asthma visits and hydrocarbon groups, on the other hand, were weaker when controlling for OC, CO, or NO 2 Table 5.
