ABSTRACTBackgroundCerebral palsy is the main cause of physical disability in childhood.ObjectivesThis study analyzed prenatal and perinatal risk factors that contribute to cerebral palsy in Brazilian children.MethodsA case-control study was conducted with 2- to 10-year-old children in the city of Aracaju, Sergipe, Brazil. The cases were population-based, selected from the Primary Health Care services. The controls were selected from the database of the Brazilian Live Births Information System. Controls were paired with cases by gender, year, and hospital of birth.ResultsA total of 570 participants (114 cases and 456 controls) were studied. Most of the participants were male, with bilateral spastic cerebral palsy. Among the prenatal factors examined, the presence of congenital anomalies was significantly different between cases and controls (OR = 54.28, [95% CI 12.55, 234.86]). The analysis of perinatal factors revealed significant differences between cases and controls in low birth weight (OR = 3.8, [95% CI 2.34, 6.16]), preterm birth (OR = 2.31, [95% CI 1.41, 3.80]), and low Apgar scores (OR = 14.73, [95% CI 5.27, 41.15]).ConclusionsThe main prenatal and perinatal factors associated with cerebral palsy in our population were congenital anomalies, low Apgar scores, low birth weight, and preterm birth. The perinatal period had more risk factors, demanding a deeper study of their causes and of possible preventive measures.

Background: Preterm birth (PTB) is an important cause of perinatal morbidity and mortality in developing societies like Nigeria. It poses huge long-term medical and financial burdens for the affected children, their families, the health care system and society at large. Objective: The objective of this study was to determine the prevalence, risk factors and birth outcome of PTB at UMTH, Nigeria. Methodology: A two-year case-control study of cases of preterm births at the UMTH, from 1st January, 2016 to 31st December, 2017 was undertaken. For each PTB, the next term delivery was taken as control. Information on socio-demographic characteristics, risk factors, gestational ages at presentation and delivery, and birth outcome were obtained from the women’s case files with proforma and compared with that of the control. Statistical analysis was done using Statistical Package for the Social Sciences (SPSS) software Version 23. The statistical significance was set at P<0.05. Results: During the period under review, there were 6,171 deliveries and preterm births constituted 291 births giving a prevalence rate of 4.7% or 47 per 1000 deliveries. The mean ages for the cases and controls were similar 26.4± 6.1 vs 26.5± 5.3 with (F=0.15, P=0.7) while the mean parity were 3.0±2.6 and 3.2±2.5 with (F=4.6, P=0.03). Nulliparity was commoner among the cases 61(24.6%) compared to the controls 34(13..7%) with X2 = 9.69, P=0.001. Similarly, 96(38.7%) of the cases were unbooked compared to 44(17.7%) among the conrols X2 = 26.9, P=0.000. About 20% of the cases had no formal education compared to 13% of the control. Preterm birth was associated with unbooking status (OR=1.82, CI: 1.40-2.36), nulliparity (OR = 2.05, CI: 1.29-3.26), previous preterm delivery (OR = 95.2, CI: 13.10-691.99) and pregnancy induced hypertension (OR = 25.45, CI: 9.13-70.92). Antepartum haemorrhage (OR = 13.89, CI: 4.92-39.25), twin gestation (OR = 18.18, CI: 2.40-137.68), Polyhydramnios (OR = 2.02, CI: 1.85-2.22) and PROM (OR = 5.39, CI: 2.87-10.15) were other risk factors independently associated with PTB. The perinatal mortality in PTB was 43(16.2%). Conclusion: The prevalence rate of PTB at the UMTH is 4.7% and is associated with previous PTB, unbooked status, twin gestation, polyhydramnious, APH and PIH. Efforts should be intensified on educating women of reproductive age group on the benefits of antenatal booking in pregnancy and quality antenatal care as this would provide ample opportunity for early detection and proper management of women at risk.

Abstract Background Preterm birth is one of the most common causes of mortality in infants. Despite advances in health care and better access to health services in many countries, preterm birth has increased over the past two decades. Methods This case control study was conducted on two groups with 100 participants including 100 preterm infants (case) and 100 term infants (control) with gender match in Kurdistan Province-Iran in 2018. The required information was collected from medical files and interviewing the mothers as to demographical information, midwifery specifications, background diseases, disease over pregnancy term, and infants’ information. Conditional logistic regression test was used to estimate the final model and compute the risk ratio. Results Multivariate regression analysis showed that the risk of preterm birth in individual with AB blood type was higher (OR=5.04; 95% CI 1.40-18.08). In addition, the risk of preterm birth was higher in the mothers with a history of stillbirth (OR=13.63; 95% CI 1.39-133.5). Preterm birth was significantly related to the history of birth diseases, history of pregnancy diseases, and using medicine for specific diseases during pregnancy. Conclusions Blood type of mother, history of still birth, history of birth disease, history of pregnancy diseases, using medicines for specific diseases, and history of preterm birth were the risk factors of preterm birth. These factors need to be taken into account before and during pregnancy. Paying more attention to these factors attenuates the rate of preterm birth and premature infants and in turn the mortality rate of infants and mothers.

ObjectivesThis study aimed to identify the risk factors associated with preterm birth, and to determine the prevalence of preterm births in the Dominican Republic.DesignCase-control study.SettingsSeven National Reference Hospitals from different regions of the Dominican Republic.ParticipantsA probabilistic sampling of both cases and controls was performed with a ratio of 2.92:1, and a power analysis was performed with α=0.05, P1=0.5, P2=0.6, and β=0.08, to yield a distribution of 394 cases and 1150 controls. Estimation of gestational age was based on neonatologist reports.Primary outcome measuresA protocol was created to obtain maternal and obstetric information.ResultsThe main risk factors were a family history of premature births (p<0.001, OR: 14.95, 95% CI 8.50 to 26.29), previous preterm birth (p=0.005, OR: 20.00; 95% CI 12.13 to 32.96), advanced maternal age (over 35 years; p<0.001, OR: 2.21; 95% CI 1.57 to 3.09), smoking (p<0.001, OR: 6.65, 95% CI 3.13 to 13.46), drug consumption (p=0.004, OR: 2.43, 95% CI 1.37 to 4.30), premature rupture of membranes (p<0.001, OR: 2.5) and reduced attendance at prenatal consultations (95% CI 6 to 7, Z=−10.294, p<0.001).ConclusionMaternal age greater than 35 years, previous preterm birth, family history of preterm births and prelabour rupture of membranes were independent risk factors for preterm birth. Adolescence, pregnancy weight gain and prenatal consultations, on the other hand, were protective factors for preterm birth. Although the prevalence of premature births in this study was 25%, this could have been biased.

Background: Preterm birth remains one of the most serious problems in obstetrics care. Its aetiology is complex and multifactorial. This study was carried out to determine risk factors for preterm birth in Dar es Salaam City in Tanzania.Methods: This case-control study was conducted in three municipal hospitals namely, Amani, Mwananyamala and Temeke in Dar es Salaam. It involved 377 pairs of women with preterm birth (cases) and term birth (controls). Eligible women who agreed to participate and who signed the consent form completed a short interview regarding demographic and lifestyle factors, had their baby examined for maturity, and had their medical records abstracted. All cases and controls were interviewed face-to-face using a specially designed questionnaire. Multivariate logistic regression after controlling for potential confounders was used to measure the strength of associations between preterm birth and related factors.Results: Several significant risk factors associations with pre-term birth were multiple pregnancies (AOR = 8.6; 95%CI 4.5-16.5; p-value <0.001), untreated vaginal discharge (AOR = 5.2; 95%CI 1.1-24.4; p-value 0.034), public prenatal care (AOR = 2.1; 95%CI 1.1-4.1; p-value 0.017), untreated urinary tract infection (AOR = 2.7; 95%CI 1.2-6.1; p-value 0.016), complication during pregnancy (AOR = 2.7; 95%CI 1.3-5.3; p-value 0.004), cervical incompetence (AOR = 11.6; 95%CI 1.1-121.5; p-value 0.04), polyhydramnios (AOR = 8.3; 95%CI 1.7-40.2; p-value 0.008), and lack of antenatal visits  (AOR = 5.1; 95%CI 1.4-17.8; p-value 0.042).Conclusion: This study has identified several risk factors for preterm birth in the city of Dar es Salaam. It is important that planners design community-based interventions to address complications from preterm birth.
