RESUMEN
Congenital malformations are defects of the morphogenesis of organs or body during the pregnancy period and are identifiable at pre- or postnatal. They are identified as the major cause of child mortality worldwide. There is a need to understand the prevalence of congenital malformations in Tigray and Ethiopia in general as surveillance data are lacking. Hence, this study was designed to investigate the burden of major congenital malformations in the Tigray Region, Northern Ethiopia. Hospital-based cross-sectional study was conducted to identify neonates with major congenital anomalies in the labor ward admitted at six major public hospitals of Tigray region, Ethiopia between January 2018 and 2019. All newborns/neonates delivered in all study hospitals during the study period were considered as the study population. The prevalence of major congenital anomalies and the distribution of each type of major congenital anomalies within total birth were calculated. Data on maternal, and newborn demographic characteristics was collected. Statistical analysis was done using SPSS and p value < 0.05 was considered significant. A total of 12,225 births and terminations were recorded in the six hospitals during the study period. Of total 12,225 births and terminations examined, 383 births had major congenital malformations and the overall prevalence of congenital malformations was 3.13% of the total births examined. Congenital anomalies (CAs) of the central nervous system specifically neural tube defects (NTDs) were the commonest anomalies in this study, found in 68.7% (263NTDs/383 CAs) of the neonates with CAs. The overall prevalence of NTDs was 2.15% (263/12,225 births) of the total births examined. Maternal factors such as women 20 years of age or younger (p < 0.0001) and women older than 35 years of age (p < 0.0001), abortion history (p < 0.0001), gravidity above 4 (p = 0.005), were more likely associated with an increased risk of babies with congenital anomalies. Fetal factors including gestational ages below 28 weeks (p < 0.0001) and above 40 weeks (p < 0.0001) were strongly associated with an increased risk of babies with congenital anomalies. However, these associated factors were not resulted from multivariable logistic regression analysis. Thus, the result might be affected by possible confounding factors. This study has shown a high prevalence of major congenital anomalies in the study community. Of the total congenital anomalies observed, most of neonates are affected with neural tube defects, a birth defect with well-established evidence having folic acid deficiency or insufficiency is the predominant cause of spina bifida and anencephaly. This just screams urgency to implement effective/mandatory/ programs to get all women of reproductive age an adequate folic acid to prevent spina bifida and anencephaly.

BACKGROUND: Recent surveillance studies in Ethiopia show an epidemic of spina bifida and anencephaly, two major neural tube birth defects that are severe and life-threatening. Our objective was to estimate proportional reductions in current stillbirth and child mortality rates in Ethiopia through folic acid-based interventions to prevent spina bifida and anencephaly. METHODS: Using secondary data from multiple sources, we estimated percent reductions in stillbirth, neonatal, infant, and under-five child mortality rates that would have occurred in Ethiopia in the year 2016 had all folic acid-preventable spina bifida and anencephaly been prevented; and the contributions of these reductions toward Ethiopia's Year 2030 Every Newborn Action Plan (ENAP) goal on stillbirth, and sustainable development goal (SDG) on child mortality rates. The 2016 prevalence of spina bifida and anencephaly in Ethiopia was assumed as 13 per 1,000 total births, with the prevention goal reaching 0.5 per 1,000 total births. RESULTS: Folic acid interventions in Ethiopia would have prevented about 41,610 cases of folic acid-preventable spina bifida and anencephaly-affected pregnancies during the year 2016. We estimate that this prevention is associated with reduction of 31,830 stillbirths and 7,335 under-five child deaths annually. The proportional contribution of this prevention toward achieving Ethiopia's ENAP goal is 54% for stillbirth, and toward SDG is 4.5% for neonatal- and 6.8% for under-five mortality. CONCLUSIONS: Spina bifida and anencephaly contribute to substantial stillbirths and child death in Ethiopia. Large-scale fortification of foods like wheat flour and salt can help achieve Ethiopia's ENAP and SDG targets addressing preventable stillbirth, neonatal, and under-five mortality.

BACKGROUND: Nutritional deficiency in pregnant women is a confirmed cause of neural tube defects (NTDs). Alongside to this background, We sought to determine the nutritional status and level of awareness on the issue of the NTDs as well as folic acid (FA) utilization among women who born infants with NTDs in Tigray region of Ethiopia. METHOD: A standard interviewer and a food frequency questionnaire was used to obtain information from mothers of cases with neural tube defects (nâ¯=â¯205) and their controls (nâ¯=â¯412). Demographic information, weekly food frequency consumption, information on awareness on the issue of the NTDs as well as folic acid (FA) use was collected. RESULT: The mean age of the mothers of the cases and controls was 26.5â¯years (range 17-43â¯years) and 26.05â¯years (range 18-40â¯years), respectively. Approximately 92.2% (189/205) of the cases and 90.5% (373/412) control mothers do not know the term folic acid (FA). Notably, all participant mothers (100%) did not understand that NTDs are a serious health problem associated with inadequate intake of FA and none of them used FA prior to conception. Food frequency analysis revealed that except for cereals (pâ¯=â¯0.12) and milk products (pâ¯=â¯0.8), the proportion of the consumed food type within seven days recalls period showed a statistically significant difference (pâ¯<â¯0.05) as compared with controls. The dietary diversity score assessment showed those attained low and high dietary diversity score were a statistically significant difference (pâ¯=â¯0.0003) and (pâ¯=â¯0.0002) respectively) as compared with controls, but the medium dietary diversity score no significant variation was found (pâ¯=â¯0.35). CONCLUSION: This study has shown none of the study participants do understand that NTDs are a serious health problem associated with inadequate intake of FA. Dietary diversity score was significantly associated with incidence of NTDs. This Ethiopian study also highlighted the need of considering the basic food in future programs of food fortification with folic acid, preconceptional folic acid supplementation and adequate dietary intake counseling. Advance research is required to find out the gene-nutrient and gene environment interactions, as well as particular causative factors associated with NTDs in Ethiopia.

INTRODUCTION: Unlike developing countries, including Ethiopia the identification of the risk factors in decreasing the burden of neural tube defects (NTDs) is well established in the developed world. Hence, we sought to determine the factors associated with NTDs in Tigray - Ethiopia. METHODS: We undergo a case-control analysis where all NTDs cases were compared to a group of controls derived randomly from the same hospitals where cases were recruited from. The NTDs survey tool which contains a standard questionnaire was prepared. Parental socio-demographic and clinical information such, maternal age, obstetric history, illnesses, drug intake, radiation, occupation, education, history of congenital anomalies, residence, exposure to pollutants such as smoking, chemicals, paternal history, and folic acid utilization was collected and analyzed using SPSS version 20. RESULT: This study has shown the maternal age, and residency, birth order 3 and 4, unplanned pregnancy, history of breastfeeding above 2â¯years, history of stillbirths, history of male gender predominance were found to have a strong association with an occurrence of NTDs (pâ¯=â¯0.0001). Though the binary logistic regression analysis showed no significant association in some of the risk factors such as maternal health and drug history, the frequency analysis showed they may have an impact on the incidence of NTDs. CONCLUSION: This study has shown the majority of the maternal risk factors and other lifestyle patterns had a significant impact on the occurrence of NTDs. Therefore, efficient monitoring of NTDs in Ethiopia is vital, so our study could be groundwork information in Ethiopia for future programs.

INTRODUCTION: Neural tube defects are the major causes of fetal loss and considerable disabilities in infants. Currently, there is no significant research on the incidence of Neural tube defects in the Tigray region of Ethiopia. OBJECTIVE: To determine the incidence and clinical pattern of the Neural Tube Defects. METHODS: A hospital-based cross-sectional study was conducted from October 2016 to June 2017. All pregnancy outcomes were examined for any externally visible birth defects and neurological integrity by trained midwives under the supervision of senior obstetrics and gynecology and a neurosurgeon. Data were collected using a survey tool to collect maternal and newborn demographic data and a checklist developed to capture newborns with Neural Tube Defects. Data were analyzed using SPSS version 20. The prevalence of NTDs was calculated per 10,000 births. RESULT: Out of the 14,903 births during the study period, a total of 195 infants were born afflicted with Neural Tube Defects. The burden of infants with anencephaly and spina bifida was 66.4 and 64.4 per 10, 000 births, respectively. The overall incidence rate of NTDs in this study was 131 per 10, 000 births of which 23% were liveborn and 77% were stillborn. The highest burden of Neural Tube Defects was observed in Adigrat Hospital from Eastern Zone of Tigray (174 per 10,000 births) and Lemlem Karl Hospital from Southern Zone of Tigray (304 per 10,000 births) compared to Kahsay Abera Hospital from Western Zone (72.8 per 10,000 births) and Sihul Hospital from North Western Zone of Tigray (69.8 per 10,000 births). CONCLUSION AND RECOMMENDATION: Assuming that the non folic acid preventable rate should be 5 per 10,000 births, our prevalence rate is 131 per 10,000 births, and then we have a rate or an epidemic that is 26 times what it should be. This just emphasizes the urgency to implement effective programs to get all women of reproductive age to have adequate folic acid to prevent all of folic acid-preventable spina bifida and anencephaly, which would prevent 96% (125/130) of spina bifida and anencephaly in the Tigray Provence.
