“…Different studies revealed that different factors could contribute for adverse birth outcome; for instance sociodemographic characteristics such as residence [21], age, marital status, education [22], occupation [23], and low socioeconomic status [24]. Related to reproductive and obstetric characteristics; parity, gravidity, birth interval [25], pregnancy plan [26], maternal nutritional status [2,21,23,24,27], past history of stillbirth, age of sexual debut [23], prolonged and obstructed labor [28], caesarean section delivery [19], history of preterm birth antepartum hemorrhage, and history of perinatal death [11].…”

Besides to this, maternal health service related factors like longer distance to walk to health facilities [21,24], and lack of antenatal care follow-up [11,20,22,24]. Additionally environmental factors such as water supply [29], washing hands with water only, not having separate kitchen room, using firewood for cooking, and using kerosene for cooking [30] could predict adverse birth outcomes.…”

Background: Adverse birth outcome which attributes to most perinatal deaths is an important indicator of child health and survival. Hence, this study aims to identify determinants of adverse birth outcome among mothers who gave birth in public hospitals of Tigrai region, North Ethiopia. Methods: Hospital based case-control study was conducted in Tigrai region, Ethiopia between December 2015 and January 2016 among 405 (135 cases and 270 controls) consecutively selected mothers who gave birth in four randomly selected public Hospitals. Mothers with adverse birth outcome (preterm birth; < 37 gestational weeks at birth, low birth weight; < 2.5 kg at birth, or still birth) were the cases while mothers without adverse birth outcome (live birth, birth weight ≥ 2.5 kg and of ≥37 gestational weeks at birth) were the controls. Data were collected by interview and reviewing medical records using structured questionnaire. The collected data were entered into database using EPI info version 3.5.1 then exported to SPSS version 21 for analysis. Finally, multivariate logistic regression was used to identify determinants of adverse birth outcomes at P value < 0.05. Result: The mean age of cases and controls was 27.3 (SD = 6.6) and 26.14 (SD = 4.9) years, respectively. In a multivariate analysis; less than four antenatal care visits [AOR = 4.35, 95% CI: 1.15-13.50], not receiving dietary counseling [AOR = 11.24, 95% CI: 3.92-36.60], not using family planning methods [AOR = 4.06, 95% CI:1.35-17.34], less than 24 months inter pregnancy interval [AOR = 5.21, 95% CI: 1.89-13.86], and less than 11 g/dl hemoglobin level [AOR = 4.86, 95% CI: 1.83-14.01] were significantly associated with adverse birth outcomes. Conclusion and recommendation: The number of antenatal care visits, ever use of family planning methods, not receiving dietary counseling during antenatal care follow up visits, short inter-pregnancy interval, and low hemoglobin level were identified as independent determinants of adverse birth outcome. A concerted effort should be taken improve family planning use, and antenatal care follow-up with special emphasis to maternal nutrition to prevent adverse birth outcomes.

“…Approximately 2.7 million stillbirths and 3.6 million neonatal deaths occur each year worldwide, 98% of which are in low‐ and middle‐income countries . As an upper‐middle‐income country, China has about 150,000 stillbirths and a similar number of neonatal deaths annually . Accumulating evidence has suggested that maternal obesity may contribute to the high prevalence of such events.…”

Objective: This study aimed to examine the associations of maternal obesity in early pregnancy with adverse pregnancy outcomes. Methods: A prospective cohort analysis was performed among 18,481 Chinese nulliparous women, using data from a 2006 to 2009 trial of prenatal micronutrient supplementation. Obesity was defined as BMI ≥ 27.5 kg/m 2 . Interested outcomes included fetal loss (spontaneous abortion plus stillbirth), infant death, total mortality, and preterm and birth weight outcomes. Results: Compared with normal weight, obesity was associated with total mortality (adjusted relative risks [ARR] 1.34; 95% CI: 1.03-1.74) and fetal loss (ARR 1.51; 95% CI: 1.15-1.99) but not with infant death (ARR 0.53; 95% CI: 0.20-1.46). Further analyses showed that obesity was particularly associated with spontaneous abortion (ARR 1.51; 95% CI: 1.13-2.02) rather than stillbirth (ARR 1.52; 95% CI: 0.65-3.57). Moreover, obesity was associated with preterm birth (ARR 1.59; 95% CI: 1.25-2.02), macrosomia (ARR 3.71, 95% CI: 3.01-4.59), and large for gestational age (ARR 2.93; 95% CI: 2.49-3.47). Conclusions: Maternal obesity in early pregnancy is associated with various adverse pregnancy outcomes in Chinese nulliparous women, suggesting the importance of an appropriate weight before and during pregnancy.

“…The NMNMSS was established in Oct. 2010[26] in health facilities whose annual deliveries were more than 1000 and which were selected from 326 districts or counties in 30 provinces to surveillance national maternal deaths and maternal near misses. Because some districts or counties did not have hospitals with the required number of births, especially in rural areas, large hospitals in urban districts were oversampled, particularly in central and western regions (S1 Table)[27]. …”

ObjectiveThe accuracy of a population-based sex ratio at birth (SRB) in China has long been questioned. To depict a more accurate profile, the present study used data from a national surveillance system for health facility births to explore the characteristics of SRB in China.MethodsData from China’s National Maternal Near Miss Surveillance System between 2012 and 2015 were used. We restricted the analysis to live births of ≥28 completed gestational weeks or ≥1000 g birth weight. The strength of association between obstetric characteristics and SRB was examined using logistic regression, taking into account the sampling strategy and clustering of births within health facilities.ResultsThere were 2,785,513 boys and 2,549,269 girls born alive between 2012 and 2015 in 441 health facilities. The SRB was 111.04 in 2012, 110.16 in 2013, 108.79 in 2014, and 109.53 in 2015. The SRB was high in the eastern region, especially in rural areas. The SRBs increased with mother’s age and decreased with mother’s education. The SRB in women who were pregnant for the first time was 104.30. The SRB in primipara was normal (104.35), but it was extremely high in non-primipara, especially for women with three or more parities (141.76); only 5.26% of live births fell within this group. The SRBs increased significantly by the number of parities, especially in the rural areas of the central region. After adjustment for sociodemographic factors, women with three or more parities were 1.39 (95% CI 1.34, 1.43) times more likely to give birth to a boy compared with primiparae who were pregnant for the first time.ConclusionOur analysis suggests that the SRB was lower than what was reported officially but higher than normal. The government should keep strengthening supervision to prevent sex-selection, especially in the wake of the two-child policy implemented in 2015.
