Prevalence and Risk Factors for Newborn Anemia in Southwestern Uganda: A Cross-Sectional Study.

Introduction: The global prevalence of maternal anemia is about 42%, and in sub-Saharan Africa, the prevalence of newborn anemia ranges from 25% to 30%. Anemia in newborn babies may cause complications such as delayed brain maturation and arrested growth. However, there is limited data on the prevalence of newborn anemia and its risk factors in people living in resource-limited settings. Objectives: We determined the prevalence and risk factors for newborn anemia and its correlation with maternal anemia in southwestern Uganda. Methods: This was a cross sectional study of 352 pregnant women presenting to the Mbarara Regional Referral Hospital for delivery. We collected maternal blood in labor and umbilical cord blood from the placental vein. We measured hemoglobin using a point-of-care Hemocue machine. We used summary statistics to characterize the study participants and compared demographic characteristics and outcomes using chi-square, t-test, and Wilcoxon rank sum analyses. We defined newborn anemia as umbilical cord hemoglobin <13 g/dl and measured the relationship between maternal and umbilical cord hemoglobin using linear regression analysis. Results: The prevalence of newborn anemia was 17%. Maternal parity was significantly higher for anemic than nonanemic newborns (3 versus 2, P=0.01). The mean age in years (SD) was significantly lower for participants with umbilical cord hemoglobin <13 g/dl than those ≥13 g/dl (26 years [5.6] versus 28 [6.3], P=0.01). In multivariable linear regression analysis, a 1-point decrease in maternal hemoglobin was associated with a 0.14-point decrease in umbilical cord hemoglobin (P=0.02). Each one-unit increase in parity was associated with a 0.25-point decrease in umbilical cord hemoglobin (P=0.01). Cesarean delivery was associated with a 0.46-point lower umbilical cord hemoglobin level compared with vaginal delivery (P=0.03). Conclusions: We found a significant association between maternal and newborn hemoglobin, underscoring the importance of preventing and correcting maternal anemia in pregnancy. Furthermore, maternal anemia should be considered a risk factor for neonatal anemia.

Prevalence and risk factors for newborn anemia in southwestern Uganda: a prospective cohort study.

Introduction: The global prevalence of anemia in pregnancy is about 42%, and in sub-Saharan Africa, the prevalence of newborn anemia ranges from 25-30%. Anemia in newborn babies may cause complications such as delayed brain maturation and arrested growth. However, there is limited data on prevalence of newborn anemia and its risk factors in people living in resource-limited settings. Objectives: We determined the prevalence and risk factors for newborn anemia and its correlation with maternal anemia in southwestern Uganda. Methods: This was a prospective cohort study of 352 pregnant women presenting to Mbarara Regional Referral Hospital for delivery. We collected maternal blood in labor and umbilical cord blood from the placental vein, as a proxy for newborn hemoglobin. We estimated hemoglobin using a point-of-care Hemocue machine. We used summary statistics to characterize the cohort, and compared demographic characteristics and outcomes using Chi-square, t-test, and Wilcoxon Ranksum analyses. We defined newborn anemia as umbilical cord hemoglobin < 13g/dl and estimated the relationship between maternal and umbilical cord hemoglobin using linear regression analysis, adjusting for potential confounders. Results: The prevalence of newborn anemia was 17%. The average maternal parity was significantly higher for anemic and non-anemic newborns (3.5 versus 2.8, P = 0.01). Mean age [SD] was significantly lower for participants with umbilical cord hemoglobin < 13g/dl than those > = 13 g/dl, (26 [5.6] versus 28 [6.3], P = 0.01). In multivariable linear regression analysis, a 1-point decrease in maternal hemoglobin was associated with a 0.14-point decrease in umbilical cord hemoglobin (P = 0.02). Each one-unit increase in maternal parity was associated with a 0.25-point decrease in umbilical cord hemoglobin (P = 0.01). Cesarean delivery was associated with a 0.46-point lower umbilical cord hemoglobin level compared to vaginal delivery (P = 0.03). Conclusions: We found a significant correlation between maternal and newborn hemoglobin levels, underscoring the importance of preventing and correcting maternal anemia in pregnancy. Furthermore, maternal anemia should be considered a risk factor neonatal anemia.

Risk Factors for Obstetric Anal Sphincter Injuries among Women Delivering at a Tertiary Hospital in Southwestern Uganda.

BACKGROUND: Obstetric anal sphincter injuries (OASIS) arise from perineal trauma during vaginal delivery and are associated with poor maternal health outcomes. Most OASIS occur in unattended deliveries in resource-limited settings. However, even in facilities where deliveries are attended by skilled personnel, a number of women still get OASIS. OBJECTIVES: To determine the incidence and risk factors for obstetric anal sphincter injuries among women delivering at Mbarara Regional Referral Hospital (MRRH). METHODS: We conducted an unmatched hospital-based case control study, with the ratio of cases to controls of 1 : 2 (80 cases and 160 controls). We defined a case as a mother who got a third- or fourth-degree perineal tear after vaginal delivery while the controls recruited were the next two mothers who delivered vaginally without a third- or fourth-degree perineal tear. A questionnaire and participants' medical records review were used to obtain sociodemographic and clinical data. We estimated the incidence of OASIS and performed univariable and multivariable logistic regression to identify the associated risk factors. RESULTS: The cumulative incidence for OASIS during the study period was 6.6%. The risk factors for OASIS were 2nd stage of labour ≥1 hour (aOR 6.07, 95%CI 1.86-19.82, p=0.003), having episiotomy performed during labour (aOR 2.57, 95%CI 1.07-6.17, p=0.035), perineum support during delivery (aOR 0.03, 95%CI 0.01-0.12, p < 0.001), and monthly income of >50,000 shillings (aOR 0.09, 95%CI 0.03-0.28, p < 0.001). Conclusions and Recommendations. The risk factors for obstetric anal sphincter injury were prolonged second stage of labour and performing episiotomies during deliveries while higher monthly income and perineum support during delivery were protective. We recommend routine support to the perineum during delivery. Care should be taken in mothers with episiotomies, as they can extend and cause OASIS.

Frequency of HIV status disclosure, associated factors and outcomes among HIV positive pregnant women at Mbarara Regional Referral Hospital, southwestern Uganda.

INTRODUCTION: Positive HIV results disclosure plays a significant role in the successful prevention and care of HIV infected patients. It provides significant social and health benefits to the individual and the community. Non-disclosure is one of the contextual factors driving the HIV epidemic in Uganda. Study objectives: to determine the frequency of HIV disclosure, associated factors and disclosure outcomes among HIV positive pregnant women at Mbarara Hospital, southwestern Uganda. METHODS: A cross-sectional study using quantitative and qualitative methods among a group of HIV positive pregnant women attending antenatal clinic was done and consecutive sampling conducted. RESULTS: The total participant recruitment was 103, of which 88 (85.4%) had disclosed their serostatus with 57% disclosure to their partners. About 80% had disclosed within less than 2 months of testing HIV positive. Reasons for disclosure included their partners having disclosed to them (27.3%), caring partners (27.3%) and encouragement by health workers (25.0%). Following disclosure, 74%) were comforted and 6.8% were verbally abused. Reasons for non-disclosure were fear of abandonment (33.3%), being beaten (33.3%) and loss of financial and emotional support (13.3%). The factors associated with disclosure were age 26-35 years (OR 3.9, 95% CI 1.03-15.16), primary education (OR 3.53, 95%CI 1.10-11.307) and urban dwelling (OR 4.22, 95% CI 1.27-14.01). CONCLUSION: Participants disclosed mainly to their partners and were comforted and many of them were encouraged by the health workers. There is need to optimize disclosure merits to enable increased participation in treatment and support programs.

Puerperal sepsis, the leading cause of maternal deaths at a Tertiary University Teaching Hospital in Uganda.

BACKGROUND: Maternal mortality is highest in sub-Saharan Africa. In Uganda, the WHO- MDG 5 (aimed at reducing maternal mortality by 75 % between 1990 and 2015) has not been attained. The current maternal mortality ratio (MMR) in Uganda is 438 per 100,000 live births coming from 550 per 100,000 in 1990. This study sets out to find causes and predictors of maternal deaths in a tertiary University teaching Hospital in Uganda. METHODS: The study was a retrospective unmatched case control study which was carried out at the maternity unit of Mbarara Regional Referral Hospital (MRRH). The sample included pregnant women aged 15-49 years admitted to the Maternity unit between January 2011 and November 2014. Data from patient charts of 139 maternal deaths (cases) and 417 controls was collected using a standard audit/data extraction form. Multivariable logistic regression analysis was used to assess for the factors associated with maternal mortality. RESULTS: Direct causes of mortality accounted for 77.7 % while indirect causes contributed 22.3 %. The most frequent cause of maternal mortality was puerperal sepsis (30.9 %), followed by obstetric hemorrhage (21.6 %), hypertensive disorders in pregnancy (14.4 %), abortion complications (10.8 %). Malaria was the commonest indirect cause of mortality accounting for 8.92 %. On multivariable logistic regression analysis, the factors associated with maternal mortality were: primary or no education (OR 1.9; 95 % CI, 1.0-3.3); HIV positive sero-status (OR, 3.6; 95 % CI, 1.9-7.0); no antenatal care attendance (OR 3.6; 95 % CI, 1.8-7.0); rural dwellers (OR, 4.5; 95 % CI, 2.5-8.3); having been referred from another health facility (OR 5.0; 95 % CI, 2.9-10.0); delay to seek health care (delay-1) (OR 36.9; 95 % CI, 16.2-84.4). CONCLUSIONS: Most maternal deaths occur among mothers from rural areas, uneducated, HIV positive, unbooked mothers (lack of antenatal care), referred mothers in critical conditions and mothers delaying to seek health care. Puerperal sepsis is the leading cause of maternal deaths at Mbarara Regional Referral Hospital. Therefore more research into puerperal sepsis to describe the microbiology and epidemiology of sepsis is recommended.
