Abstract

Background

Exposure to Indoor air pollution (IAP) during pregnancy can cause numerous health conditions in both the mother and new-born. Use of biomass as cooking fuel is a major factor that could lead to IAP, and low birth weight (LBW) is one of the many adverse birth outcomes. This research study measured concentrations of PM_2.5, a hazardous pollutant to determine IAP and its association with LBW.

Objective

To determine the association of indoor air pollution and birthweight among pregnant women in a rural area.

Methods and materials

Socio-demographic, household and cooking characteristics of the participants were collected using pretested questionnaire. ANOVA, t-test and Multiple regression analysis done. PM_2.5 concentrations for IAP were measured using an Air Quality monitor.

Results

The incidence of LBW in pregnant women exposed to IAP was 24.6 %. There was association of LBW among pregnant women with, history of past adverse birth outcomes [AOR: 1.9176, 95 % CI (1.0147, 4.2349)], dampness in household [AOR: 1.6837, 95 % CI (1.3284, 4.061)] and, household PM_2.5 concentrations exceeding 40 μg/m³ [AOR: 1.0692, 95 % CI: (1.0234, 1.1192)]. Every increase in 10 μg/m³ PM_2.5 concentration showed the odds of increase in low birth weight by a factor of 1.0635.

Conclusion

The present study concluded that birth weight in new born was affected by maternal exposure to factors causing indoor air pollution.

农村地区室内空气污染与出生体重的关系：一项纵向研究

怀孕期间暴露于室内空气污染（IAP）可导致母亲和新生儿出现多种健康问题。使用生物质作为烹饪燃料是可能导致IAP的一个主要因素，低出生体重（LBW）是许多不良出生结果之一。本研究测量了有害污染物PM2.5的浓度，以确定IAP及其与LBW的关系。目的了解某农村地区孕妇室内空气污染与出生体重的关系。方法与材料采用预测问卷法收集调查对象的社会人口学、家庭和烹饪特征。进行方差分析、t检验和多元回归分析。使用空气质量监测器测量IAP的PM2.5浓度。结果暴露于IAP的孕妇LBW发生率为24.6%。孕妇LBW与既往不良分娩结局史[AOR: 1.9176, 95% CI(1.0147, 4.2349)]、家庭湿度[AOR: 1.6837, 95% CI(1.3284, 4.061)]和家庭PM2.5浓度超过40 μg/m3 [AOR: 1.0692, 95% CI: 1.0234, 1.1192]有关。PM2.5浓度每增加10 μg/m3，低出生体重增加的几率为1.0635倍。结论新生儿出生体重与母亲接触室内空气污染因素有关。
