| description | Objectives
To identify risk factors for small-for-gestational age (SGA) for counties in central Appalachian states (Kentucky
(KY), Tennessee (TN), Virginia (VA), and West Virginia (WV)) with varied coal mining activities.
Material and Methods
Live birth certificate files (1990–2002) were used for obtaining SGA prevalence rates for mothers based on the
coal mining activities of their counties of residence, mountain-top mining (MTM) activities, underground mining activities
but no mountain-top mining activity (non-MTM), or having no mining activities (non-mining). Co-variable information,
including maternal tobacco use, was also obtained from the live birth certificate. Adjusted odds ratios were obtained using
multivariable logistic regression comparing SGA prevalence rates for counties with coal mining activities to those without
coal mining activities and comparing SGA prevalence rates for counties with coal mining activities for those with
and without mountain-top mining activities. Comparisons were also made among those who had reported tobacco use
and those who had not.
Results
Both tobacco use prevalence and SGA prevalence were significantly greater for mining
counties than for non-mining counties and for MTM counties than for non-MTM counties. Adjustment for tobacco use
alone explained 50% of the increased SGA risk for mining counties and 75% of the risk for MTM counties, including demographic
pre-natal care co-variables that explained 75% of the increased SGA risk for mining counties and 100% of the
risk for MTM. The increased risk of SGA was limited to the third trimester births among tobacco users and independent
of the mining activities of their counties of residence.
Conclusions
This study demonstrates that the increased prevalence
of SGA among residents of counties with mining activity was primarily explained by the differences in maternal tobacco
use prevalence, an effect that itself was gestational-age dependent. Self-reported tobacco use marked the population at the
increased risk for SGA in central Appalachian states. Int J Occup Med Environ Health 2018;31(1):11–23 |
