Background: Small for gestational age (SGA) is a key contributor to premature deaths and long-term complications in life. Improved characterization of maternal risk factors associated with this adverse outcome is needed to inform the development of interventions, track progress, and reduce the disease burden. This study aimed to identify socioeconomic, demographic, and clinical factors associated with SGA in Mexico.Methods: We analyzed administrative data from 1,841,477 singletons collected by the National Information Subsystem of Livebirths during 2017. Small-for-gestational-age was defined as being <10th centiles according to the INTERGROWTH-21st standards. The comparison group was defined as being in ≥10th centiles. We fitted logistic regression models to determine odds ratios for the maternal factors associated with SGA.Results: Among the 1,841,477 singletons, 51% were male, 6.7% were SGA, 6.1% were term-SGA, and 0.5% were preterm-SGA. Maternal education presented a protective gradient of being SGA among mothers who achieved 1 to 6 years of education (adjusted odds ratio (aOR)0.95; 95% CI:0.91,0.99), 7 to 9 years (aOR 0.86; 95% CI:0.83,0.89), 10 to 12 years (aOR 0.75; 95% CI: 0.72, 0.79) and > 12 years (aOR 0.63; 95% CI:0.6,0.66) compared with those without education. SGA was particularly likely to occur among primiparous (aOR 1.42; 95% CI: 1.39, 1.43), mothers living in very high deprivation localities (aOR 1.39; 95% CI: 1.36, 1.43), young (aOR 1.04; 95% CI: 1.02, 1.06), advanced age (aOR 1.14; 95% CI 1.09, 1.19), and mothers living in areas above 2,000 m (aOR 1.69; 95% CI: 1.65, 1.73). Antenatal care was associated with a reduced risk of SGA by 30% (aOR 0.7; 95% CI:0.67,0.73), 23% (OR 0.77; 95% CI:0.74,0.8), and 21% (OR 0.79; 95% CI:0.75,0.83), compared with those mothers who never received antenatal care, when women visited the clinic at the first, second and third trimester, respectively.Conclusion: Almost 7% of live births were found to be SGA. Parity, maternal age, education, place of residence, and social deprivation were significantly associated with this outcome. Antenatal care was protective. These findings imply that interventions focusing on early and adequate contact with health care facilities, reproductive health counseling, and maternal education should reduce SGA in Mexico.

Background: Low birth weight (LBW) is a major risk factor for death and disease in the fetus and newborn infant. However, the study about LBW and maternal risk factors involved in Indonesia is still limited. Objective: The present study attempted to examine the association of maternal risk factors including mother’s age, mother and husband education, mother and husband occupation and wealth, ANC visit, desired pregnancy and obstetric complication toward the occurrence of low birth weight infant across region and family wealthy. Methods: This study employed the data from the national survey of Indonesia Demographic and Health Survey (IDHS). The latest births from married women who gave birth within 2 years (2011 and 2012) preceding the IDHS were considered as sample selection. It was approximately 15,126 respondents. The predicted risks of low birth weight were estimated using multilevel logistic analysis. Results: Data were collected on 15,126 pregnant women who reported 10.2% were with LBW infants. When using the multilevel logistic analysis, the factors associated with LBW were maternal delivery-baby age, mother’s education, antenatal care and pregnancy complication at significant levels of 0.01. Conclusion: The prevalence of preterm infants in this study was quite high. Factors affecting LBW were maternal age, maternal education, ANC visits and pregnancy complication. The ANC visit of pregnant women is a potential and feasible activity to reduce the incidence of LBW.

Background Small for gestational age (SGA) neonates often have intrauterine growth restriction due to placental insufficiency and chronic hypoxia. These conditions may cause developmental impairment, psychosocial disabilities, or metabolic dysfunction in later life. Previous studies have shown greater incidence of speech and language disabilities, learning impairment, and neuromotor dysfunction in term SGA infants compared to term appropriate for gestational age (AGA) infants.Objective To compare hearing loss in SGA and AGA neonates using otoocoustic emission (OAE) tests and to study correlations between maternal risk factors and hearing loss in SGA neonates.Methods A cross-sectional study was performed in St. Borromeus Hospital, Limijati Hospital, and Melinda Hospital in Bandung from February to May 2010. Study subjects consisted of full-term neonates born in these three hospitals. A retrospective medical record review was performed for this study. Statistical analysis was done by multivariable logistic-regression.Results There was a total of 4279 subjects in our study, including 100 SGA neonates and 4179 AGA neonates. We observed a greater percentage of OAE 'refer' (indicating abnormal OAE) results in the SGA group compared to the AGA group (P<0.001, Z=13.247). For suhjects with OAE 'refer' results, we also analyzed the correlation to the following maternal risk factors: smoking, hypertension, diabetes mellitus and asthma. We also found significant differences between  those with and without each of the four maternal risk factors studied (P< 0.001). By using multivariant analysis to compare SGA and AGA neonates, we found the odds ratio (OR) to he 4.34 (95% CI 2.52 to 7.49, P=0.001), meaning the SGA group had a 4.34 times higher risk of hearing loss than the AGA group.Conclusion SGA neonates had a higher risk of hearing loss than AGA neonates. In addition, maternal smoking, hypertension, diabetes mellitus and asthma significantly correlated to hearing loss in all newborns. [

The maternal risk factors that correlate with small-for-dateness among twins have been analyzed using a sample of 659 twin pairs and a matched sample of singletons. Non-marital status, job involvement, and the previous delivery of a low-birth weight (<2,500g) infant present a negative interaction with twinning, as low gestational age-adjusted birth weight does not correlate significantly with these risk factors among twin gestations, while it does among singleton gestations. On the other hand, the effects of parity, habitual maternal weight, smoking during pregnancy, and twinning are additive on gestational age-adjusted birth weight. Indeed, the decrease in adjusted birth weight associated with these risk factors is of the same magnitude among twins and singletons and is statistically significant in both cases. These findings suggest that exposure of twin pregnancies to these latter risk factors, and particularly to smoking during pregnancy, can lead to the delivery of newborns with extremely low birth weights.
