Background: Maternal exposure to kitchen fuel smoke may lead to impaired fetal growth.
Objective: To study the effect of exposure to various kitchen fuels on birth weight.
Study Type: Retrospective analytical.
Study Setting: Hospital based.
Study Subjects: Mothers and their newborns.
Inclusion Criteria: Mothers registered in first trimester with minimum 3 visits, non-anemic, full-term, and singleton delivery.
Exclusion Criteria: History of Pregnancy Induced Hypertension (PIH), Diabetes Mellitus (DM), tobacco chewers or mishri users.
Sample Size: 328 mothers and their new-borne.
Study Period: Six months. Study tools: Chi-square, Z-test, ANOVA, and binary logistic regression.
Results: Effect of confounders on birth weight was tested and found to be non-significant. Mean ± SD of birth weight was 2.669 ± 0.442 in Liquid Petroleium Gas (LPG) users (n = 178), 2.465 ± 0.465 in wood users (n = 94), 2.557 ± 0.603 in LPG + wood users (n = 27) and 2.617 ± 0.470 in kerosene users (n = 29). Infants born to wood users had lowest birth weight and averagely 204 g lighter than LPG users (F = 4.056, P < 0.01). Percentage of newborns with low birth weight (LBW) in wood users was 44.68% which was significantly higher than in LPG users (24.16%), LPG + wood users (40.74%) and in kerosene users (34.48%) (Chi-square = 12.926, P < 0.01). As duration of exposure to wood fuel increases there is significant decline in birth weight (F = 3.825, P < 0.05). By using logistic regression type of fuel is only best predictor.
Conclusion: Cooking with wood fuel is a significant risk-factor for LBW, which is modifiable.

Birth weight and prepubertal growth trajectory had a combined effect on pubertal initiation in girls.

Aim: Most studies of prepubertal weight and puberty have not used continuous or long follow-up periods. We explored the effect that birth weight and growth trajectories from 0-9 years of age had on starting puberty.
Methods: Data were obtained from 1510 children in Tianjin, China, who were born in 2013 and selected by cluster random sampling.

The brain develops most rapidly during pregnancy and early neonatal months. While prior electrophysiological studies have shown that aperiodic brain activity undergoes changes across infancy to adulthood, the role of gestational duration in aperiodic and periodic activity remains unknown. In this study, we aimed to bridge this gap by examining the associations between gestational duration and aperiodic and periodic activity in the EEG power spectrum in both neonates and toddlers.

Globally, obesity prevalence has progressively increased and is now at epidemic levels; this trend is mirrored in women of childbearing age. There is a high level of evidence that maternal obesity is associated with a range of adverse pregnancy complications and neonatal outcomes, such as hypertensive disorders of pregnancy, gestational diabetes mellitus (GDM), large for gestational age (LGA) fetuses, premature birth, stillbirth, cesarean section, and postpartum hemorrhage, among certain others. This systematic review aimed to comprehensively evaluate the relationship between maternal obesity and health outcomes for both mothers and infants.

Background: Triglyceride-glucose (TyG) index was suggested as a possible surrogate for insulin resistance and a predictor for cardiovascular diseases and diabetes in the non-pregnant population. However, the relationship between TyG index in early pregnancy and adverse pregnancy outcomes (APOs), and the contribution of pre-pregnancy body mass index (BMI) was still illusive.
Methods: A large retrospective cohort study involving 67,936 pregnant Chinese women between 2017 and 2022 was conducted.
