“…The risk of preterm birth was higher in women exposed to solid fuel while cooking. Our findings are consistent with the multicentric observational study done in Nepal ( 19 ) and other studies that provide evidence of solid fuels for cooking and increased risk of preterm birth ( 19 , 20 , 20 – 22 ). The combustion of biomass fuel emits high concentrations of airborne particulate matter and toxic chemicals, including carbon monoxide (CO), nitrogen dioxide (NO 2 ), and sulfur dioxide (SO 2 ).…”

Background: Preterm birth is a significant cause of neonatal death globally. Nepal is in the 20th position in the world, with the highest rate of preterm deliveries. The risk factors of preterm birth have not been fully identified and established in Nepal. The study aims to identify risk factors of preterm birth among women who underwent delivery in a tertiary maternal hospital in Nepal.Methods: This study employed a hospital-based matched case-control study design. The case included women who delivered before 37 weeks of gestation, and women who delivered between 37 and 42 weeks of gestation served as controls. The ratio of the case to control was 1:2, and matching was done for the type of delivery. The first author collected the data in the Paropakar Maternity and Women's Hospital between December 2015 and January 2016. Face-to-face interviews were conducted using a structured questionnaire. Backward conditional logistic regression was performed to identify the independent risk factors of preterm birth.Results: Antihelminthic treatment during pregnancy was found to be protective for preterm birth. Women performing intensive physical work during their pregnancy and women exposed to indoor air pollution were more likely to have a preterm birth than women not performing intensive physical work and women not exposed to indoor pollution, respectively.Conclusions: Women who had not consumed antihelminthic drugs per protocol, those exposed to indoor air pollution, and those who performed intensive work during pregnancy were at higher risk for preterm birth. Maternal health programs can encourage women to consume antihelminthic drugs, take proper rest during pregnancy, and prevent indoor pollution exposure.

“…During the second trimester, relationships between anemia and infant outcomes were signi cant for PTB (OR (95% CI) 1.37 (1.15-1.64)) and stillbirth (OR (95% CI) 2.22 (1.36-3.65)) but not for the other outcomes. During the third trimester, anemia was associated with increased odds of the following adverse birth outcomes: LBW (OR (95% CI) 1 45. (1.23-1.70)), VLBW (OR (95% CI) 2.20 (1.43-3.38)) and PTB (OR (95% CI) 1.49 (1.30-1.71)) but decreased odds of SGA (OR (95% CI) 0.89 (0.80-0.98)).…”

Background Growing evidence suggests low and high maternal hemoglobin (Hb) concentrations may have adverse consequences for maternal and child health. There remain questions on specific Hb thresholds to define anemia and high Hb as well as how cutoffs may vary by anemia etiology and timing of assessment. Methods We conducted an updated systematic review (using PubMed and Cochrane Review) on the association between anemia (< 110 g/L) and high (≥ 130 g/L) maternal Hb concentrations at different stages of gestation (preconception; first, second, and third trimesters), as well as at any time point in pregnancy, and a range of maternal and infant health outcomes. We examined different cutoffs for defining anemia and high hemoglobin concentrations and performed stratified analyses by iron-deficiency anemia. We conducted a meta-analysis to obtain odds ratios, (OR), 95% confidence intervals. Results The updated systematic review included 148 studies. Anemia at any timepoint in pregnancy was associated with: low birthweight, LBW (OR (95% CI) 1.28 (1.22–1.35)), very low birthweight, VLBW (2.15 (1.47–3.13)), preterm birth, PTB (1.35 (1.29–1.42)), small-for-gestational age, SGA (1.11 (1.02–1.19)), stillbirth 1.43 (1.24–1.65)), perinatal mortality (1.75 (1.28–2.39)), neonatal mortality (1.25 (1.16–1.34), postpartum hemorrhage (1.69 (1.45–1.97)), transfusion (3.68 (2.58–5.26)), pre-eclampsia (1.57 (1.23–2.01)), and prenatal depression (1.44 (1.24–1.68)). For maternal mortality, the OR was higher when anemia was defined as Hb < 90 (4.83 (2.17–10.74)) compared with Hb < 100 (2.87 (1.08–7.67)). High maternal Hb was associated with: VLBW (1.35 (1.16–1.57)), PTB (1.12 (1.00-1.25)), SGA (1.17 (1.09–1.25)), stillbirth (1.32 (1.09–1.60)), maternal mortality (2.01 (1.12–3.61)), gestational diabetes (1.71 (1.19–2.46)), and pre-eclampsia (1.34 (1.16–1.56)). Stronger associations were noted earlier in pregnancy for anemia and adverse birth outcomes while the role of timing of high Hb was inconsistent. For anemia, lower cutoffs were associated with greater odds of poor outcomes; for high Hb, data were too limited to identify patterns. Information on anemia etiology was limited; relationships did not vary by iron-deficiency anemia. Conclusions Both anemia and high maternal Hb concentrations during pregnancy are strong predictors of adverse maternal and infant health outcomes. Additional research is need to establish healthy reference ranges and design effective interventions to optimize maternal Hb during pregnancy.

“…Firewood smoke exposure has a detrimental effect on not just their respiratory health but also on their reproductive health. The adverse perinatal outcomes associated with biomass fuel smoke exposure in pregnant women are well documented and include but are not limited to low-birth-weight deliveries [ 23 – 25 ], preterm births [ 23 – 25 ], stillbirths [ 24 , 25 ] and neonatal mortality [ 25 , 26 ]. Thus, this research area addresses a timely and significant health issue that can negatively impact both present and future generations, both directly and indirectly.…”

Impact of solid fuel usage on respiratory symptoms among reproductive aged women: a cross-sectional study in Sri Lanka

et al. 2022

Background Worldwide, around 3 billion people rely on solid fuel for their daily energy needs. Household air pollution secondary to solid fuel burning is a major risk factor for respiratory mobility among vulnerable populations. This study aimed to investigate the respiratory symptoms associated with solid fuel usage, the level of kitchen fuel smoke exposure and its association with respiratory symptoms among reproductive-aged women in Sri Lanka, where most households exclusively use firewood as the primary cooking fuel. Methods A descriptive cross-sectional study was conducted among 403 reproductive-aged women (15 to 49 years) in the Central Province, Sri Lanka. A structured interviewer-administered questionnaire was used to collect data, and an exposure assessment was done using a breath carbon monoxide monitor. Results After adjusting for potential confounding factors by the logistic regression models, the odds ratios (OR) of the liquid petroleum gas-only users for at least one respiratory symptom relevant to cough (OR: 0.39; 95% confidence interval [CI]: 0.20–0.78), wheezing (OR: 0.47; 95% [CI]: 0.26–0.87), and dyspnea (OR: 0.44; 95% CI: 0.24–0.84) were significantly lower compared to firewood-only users. The mean of expired air carbon monoxide and estimated carboxyhemoglobin levels of liquid petroleum gas-only users (2.84 ± 2.85 ppm; 1.08 ± 0.46%) were significantly lower than those of firewood-only users (5.27 ± 4.64 ppm; 1.47 ± 0.74%). Conclusions The use of firewood increased the risk of respiratory symptoms among reproductive-aged women in Sri Lanka. Health education focused on positive behavioral changes and effective and efficient clean energy policies are recommended to mitigate the risk associated with solid fuel smoke exposure.
