“…A similar association has been found in several other studies conducted in developing countries such as Guatemala, India, Pakistan, China, and Zimbabwe. [26][27][28] Pregnant women in Bangladesh, like other developing countries, are not exempted from cooking regularly and are exposed to highly pollutant carbon dioxide (CO 2 ) and carbon monoxide (CO) laden air for a prolonged period of time. 29, 30 This is a concern as polluted air may hamper the required transplacental oxygen supply to the fetus and can cause intrauterine growth retardation (IUGR) of varying degrees and types.…”

Background. More than 90% of all low birthweight (LBW) babies are born in developing countries, and half of the population in developing nations uses solid fuels as their primary source of energy for cooking. An association between household use of solid biomass fuels and reduced newborn weight has been found in a number of countries. Bangladesh has a high prevalence of LBW babies (22%), and 88% of the population use solid fuels for cooking. Objectives. This study aims to explore whether indoor air pollution is associated with LBW in Bangladesh, an important determinant of infant mortality and morbidity. Methods. The 2011 Bangladesh Demographic and Health Survey (BDHS) was used for the present analysis. The total number of births reported in the previous five years by respondents in the survey sample was 8,753. Mothers' recall of their baby's weight was the dependent dichotomous variable. A mixed effects logistic regression model was fitted using region as a random effect and several independent fixed effects. Results. High pollutant cooking fuels, such as coal and wood, resulted in higher odds of having a LBW child compared to use of electricity/gas (odds ratio (OR): 2.6, confidence interval (CI): 1.1–6.2 and OR: 1.1, CI: 1.0–1.2). Factors which lowered the odds include mothers with a bachelor's degree or higher education (OR: 0.6, CI: 0.4–0.9), third order children (OR: 0.8, CI: 0.6–0.9), fourth or higher order children (OR: 0.8, CI: 0.6–1.0), having a male child (OR: 0.7, CI: 0.7–0.8), and receiving sufficient antenatal care (OR: 0.8, CI: 0.6–0.9). Factors which increase the odds of having a LBW infant include mothers who are underweight compared to normal weight mothers (OR: 1.1, CI: 1.1–1.2), mistimed pregnancies (OR: 1.2, CI: 1.0–1.4), or unplanned pregnancies (OR: 1.3, CI: 1.0–1.7), compared to planned pregnancies. Conclusions. This is the first paper to show an association between use of highly pollutant biomass fuel and prevalence of LBW babies in Bangladesh, suggesting that besides polluting the air and causing respiratory illnesses, biomass fuel combustion may also affect the health of fetuses in utero. Further longitudinal studies are required to establish this finding among mothers in developing countries.

ObjectiveTo identify the prevalence, risk factors and health impacts associated with small for gestational age (SGA) births in Nepal.MethodsA cross-sectional study was conducted in 12 public hospitals in Nepal from 1 July 2017 to 29 August 2018. A total of 60 695 babies delivered in these hospitals during the study period were eligible for inclusion. Clinical information of mothers and newborns was collected by data collectors using a data retrieval form. A semistructured interview was conducted at the time of discharge to gather sociodemographic information from women who provided the consent (n=50 392). Babies weighing less than the 10th percentile for their gestational age were classified as SGA. Demographic, obstetric and neonatal characteristics of study participants were analysed for associations with SGA. The association between SGA and likelihood of babies requiring resuscitation or resulting in stillbirth and neonatal death was also explored.ResultsThe prevalence of SGA births across the 12 hospitals observed in Nepal was 11.9%. After multiple variable adjustment, several factors were found to be associated with SGA births, including whether mothers were illiterate compared with those completing secondary and higher education (adjusted OR (AOR)=1.73; 95% CI 1.09 to 2.76), use of polluted fuel compared with use of clean fuel for cooking (AOR=1.51; 95% CI 1.16 to 1.97), first antenatal care (ANC) visit occurring during the third trimester compared with first trimester (AOR=1.82; 95% CI 1.27 to 2.61) and multiple deliveries compared with single delivery (AOR=3.07; 95% CI 1.46 to 6.46). SGA was significantly associated with stillbirth (AOR=7.30; 95% CI 6.26 to 8.52) and neonatal mortality (AOR=5.34; 95% CI 4.65 to 6.12).ConclusionsLow literacy status of mothers, use of polluted fuel for cooking, time of first ANC visit and multiple deliveries are associated with SGA births. Interventions encouraging pregnant women to attend ANC visits early can reduce the burden of SGA births.

Background: Small sized child at birth is associated with household fuel use particularly from biomass fuel type. Household air pollution is believed to affect the fetus directly through trans-placental exposure or indirectly by adversely impacting birth outcome which resulted from a small-sized child at birth. It is an important predictor of children's health and is associated with higher risk of infant and child mortality due to various contributing factors. This study ascertained the association between household fuel types, kitchen characteristics and house structure with child size at birth in Wolaita Sodo, Southern Ethiopia. Methods: A cross-sectional study among 1042 mothers paired with their child aged between 0-59 months was employed. Participants were selected using systematic random sampling from 6 Kebeles. The size of a child at birth was determined based on the mother’s report. Data were entered using Epi Data version 3.1 and analyzed using SPSS version 21. Results: The prevalence of small size at birth was 16.3%, (95% CI 14.2%-18.6%). Children were relatively equally distributed by age. The mean age of the children was 23.74 ± 14.93 months. Sixty-one percent of households used charcoal followed by biomass fuel (23.4%) for cooking activities. About 322 (30.9%) houses had one room, 504 (48.4%) houses had one door and 431 (41.4%) houses had only one window. Biomass fuel type (AOR, 3.83, 95% CI, 1.95-15.35), cooking place inside the house (AOR, 2.27, 95% CI 1.88-5.88, house without window, (AOR, 4.79, 95% CI 1.56-14.69), time spent for three or more hours in cooking, (AOR, 2.45, 95% CI 1.16-5.21) were significantly associated with child size at birth. Conclusion: Small size child at birth is still the concern of the study area. Using biomass fuel, cooking inside the house, more time spent in cooking and houses without window were determinants. Therefore, we recommend to the concerned stakeholders to work on clean fuel technologies and improving house designs to assuage related problems.
