Determinants of anemia in postpartum HIV-negative women in Dar es Salaam, Tanzania

The magnitude and associated factors of immediate postpartum anemia among women who gave birth in Ethiopia: systematic review and meta-analysis, 2023

BACKGROUND

The immediate postpartum period is a very crucial phase for both the life of the mother and her newborn baby. Anemia is the most indirect leading cause of maternal mortality. However, anemia in the immediate postpartum period is a neglected public health problem in Ethiopia. Therefore, this systematic review and meta-analysis aimed to estimate the pooled magnitude of immediate postpartum anemia and the pooled effect size of associated factors in Ethiopia.

METHODS

Searching of published studies done through PubMed, Medline, Cochrane, African index Medicus, List of Reference Index, Hinari, and Google Scholar. This systematic review and meta-analysis follow the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) godliness. The quality of studies was assessed by using a Newcastle- Ottawa Scale (NOS) assessment tool. Analysis was performed using a random effect model by using STATA 17 version software. Egger's weighted regression and I2 test were used to evaluate publication bias and heterogeneity respectively.

RESULTS

In this systematic review and meta-analysis, a total of 6 studies were included. The pooled magnitude of immediate postpartum anemia in Ethiopia was 27% (95%CI: 22, 32). Instrumental mode of delivery (OR = 3.14, 95%CI: 2.03, 4.24), mid-upper arm circumference (MUAC) measurement < 23 cm (OR = 3.19, 95%CI: 1.35, 5.03), Antepartum Hemorrhage (OR = 4.75, 95%CI: 2.46, 7.03), postpartum hemorrhage (OR = 4.67, 95%CI: 2.80, 6.55), and no iron/foliate supplementation (OR = 2.72, 95%CI: 1.85, 3.60) were the identified factors associated with developing anemia in the immediate postpartum period.

CONCLUSION

The overall pooled magnitude of anemia in the immediate postpartum period among Ethiopian women was still a moderate public health problem. Instrumental mode of delivery, mid upper arm circumference (MUAC) measurement < 23 cm, antepartum hemorrhage, postpartum hemorrhage, and no iron/foliate supplementation were the identified factors associated with higher odds of developing anemia among immediate postpartum women in Ethiopia. Therefore, midwives, and doctors, shall focus on prevention of maternal hemorrhage, nutritional advice and counseling including iron /foliate supplementation, and avoid unnecessary instrumental delivery to prevent and reduce anemia related maternal mortality and morbidity in Ethiopia.

The magnitude and associated factors of immediate postpartum anemia among women who gave birth in east Gojjam zone hospitals, northwest- Ethiopia, 2020

BACKGROUND

Globally around half a million maternal death occurred annually related to labor and delivery of which twenty percent is contributed by post-partum anemia. Postpartum anemia contributes about two percent of total maternal mortality in Ethiopia. Immediate postpartum anemia is a common public health problem in most parts of the globe, being frequent in low and middle-income countries including in the developed world. The previous studies cut off point for immediate postpartum Anemia is 11mg/dl which is the cutoff point of anemia after one week of postpartum, environmental factors like barefoot were not addressed in the previous studies and the previous studies were conducted in a single facility This study aimed to assess the magnitude and associated factors of immediate post-partum anemia among women who gave birth in East Gojjam zone hospitals, Northwest Ethiopia.

METHODS

Institutional based cross-sectional study was conducted from October 20-November 20 2020 on immediate post-partum anemia. During the study 467 study participants were included by using systematic random sampling method Data were collected using a structured interviewer-administered questionnaire and a blood sample was used for hemoglobin determination. Data were checked, coded, and entered into Epi-Data Version 4.2 and then exported to SPSS version 25 for analysis. Binary logistic regressions were done to identify predictors of immediate post-partum anemia and a 95% confidence interval of odds ratio at a p-value less than was taken as a significance level.

RESULTS

The overall magnitude of immediate postpartum anemia among mothers who gave birth in East Gojjam Zone Hospitals were found to be 21.63% (95% CI:18.12%, 25.11%), not having antenatal care follow-up (Adjusted Odds Ratio (AOR) = 2.92;95% CI:1.20,7.06), assisted instrumental delivery (AOR = 2.72; 95% CI:1.08,6.78),mid-upper arm circumferences less than 23cm (AOR = 5.75;95% CI:3.38, 9.79), antepartum hemorrhage (AOR = 4.51; 95% CI:2.42, 8.37), never wearing shoes (AOR = 2.60; 95% CI:1.10, 6.14) were found to be significantly associated with immediate postpartum anemia.

CONCLUSION

This study indicates that immediate postpartum anemia is a moderate public health problem in the study area. A more careful strategy is ideal to increase antenatal care follow-up that sticks to national guideline contact schedule, safe reduction of instrumental and cesarean deliveries to the minimum, quick and timely linkage and treatment of malnourished pregnant mothers to the center where they get adequate health care services, along with a high index of suspicion in mothers diagnosed with antepartum hemorrhage, wise and vigilant advice on consistent use of the shoe for pregnant mothers are recommended to tackle the burden of immediate post-partum anemia.

Prevalence of anaemia and its associated factors among lactating mothers in eastern Sudan: a cross-sectional study

BACKGROUND

Lactating mothers are susceptible to anaemia. Little published data are available on lactational anaemia in Africa, including Sudan. This study was conducted to assess the prevalence of and associated factors for anaemia among lactating mothers in eastern Sudan.

METHODS

A cross-sectional study was conducted and sociodemographic and clinical characteristics were gathered through a questionnaire.

RESULTS

A total of 650 lactating mothers were included in the analysis. Their median age and parity were 28.0 y (interquartile range [IQR] 23.7‒32.0) and 3.0 (IQR 2.0‒4.0), respectively. Haemoglobin (Hb) levels ranged from 7.0 to 15.0 g/dL (median 11.2 [IQR 10.4‒12.0]). Of the 650 lactating mothers, 442 (68.0%) had anaemia (Hb <12.0 g/dL). In multivariate analysis, lactating mothers with education less than the secondary level (adjusted odds ratio [AOR] 1.58 [95% confidence interval {CI} 1.05 to 2.37]) and lactating mothers who underwent caesarean delivery (AOR 1.74 [95% CI 1.17 to 2.58]) had a higher probability of being anaemic. Employment was associated to a lower frequency of anaemia (AOR 0.39 [95% CI 0.20 to 0.79]).

CONCLUSIONS

This study showed a high prevalence of anaemia among lactating mothers. Public health intervention activities designed towards education would be helpful to reduce anaemia.

Prevalence of post-partum anemia and associated factors among women attending public primary health care facilities: An institutional based cross-sectional study

Background

Severe post-partum anemia is an important cause of maternal deaths and severe morbidity in sub-Saharan Africa. In Tanzania, little information is available to guide health care professionals in ensuring good health of women after delivery. The objective of our study was to determine the prevalence of post-partum anemia and associated factors among women attending public primary health care facilities.

Materials and methods

An institutional based cross sectional study was carried out. Women in post-partum period (the period from child birth to six weeks after delivery) attending the public primary health care facilities from October to December 2019 for children vaccination were recruited. The prick method was used to obtain blood for haemoglobin estimation. Post-partum anemia was defined as a haemoglobin level of less than 11g/dl. Participants found anaemic were asked to undertake malaria and helminths parasites tests from blood and stool samples respectively. The samples were examined by an experienced laboratory scientist on study sites according to the Tanzania national standard for medical laboratories protocols.

Results

A total of 424 women were enrolled with mean age of 27.8 years (SD 5.93). Most of the participants 234(55.2%) had primary education and nearly half 198(46.7%) of them were house wives. The overall prevalence of post-partum anemia was 145(34.2%). Among the anaemic participants, 34(23.5%) had positive blood slide for malaria parasite while 15(10.3%) had positive test for stool helminths infection. Delivery by vaginal route and low parity were protective against post-partum anemia (p<0.001).Other factors that were associated with post-partum anemia included absence of a marital partner (p<0.001) and inter pregnancy interval of less than two years (p<0.001). The risk of post-partum anemia in women with less than two years interval between their last two pregnancies was about 18 times more as compared to women with more than two years interval between their last two pregnancies, (COR = 18; 95% CI 8.617–38.617).Women without marital partners were 10 times more likely to get anemia as compared to married women, (COR = 10; 01.910–54.935).

Conclusions

The prevalence of anaemia among post-partum women found in this study points to a situation of public health problem according to WHO cut-off values for the public health significance of anaemia. Inter pregnancy interval of less than two years and absence of a marital partner were associated with post-partum anemia while delivery by vaginal route and low parity were protective against post-partum anemia. Strategies should therefore be put in place to encourage thorough health education and promotion programs among both pregnant and post-partum women.

Maternal anaemia during postpartum: Preliminary findings from a cross-sectional study in Dodoma City, Tanzania

AIM

The aim of this study was to determine the prevalence and correlates of anaemia among postnatal women.

DESIGN

A cross-sectional survey was conducted from April-July, 2020, at a healthcare facility in Dodoma City.

METHODS

Haemoglobin concentration was measured by using HemoCue Hb 201+ analyser machine. Anaemia was defined as haemoglobin concentration of <11 g/dl. Chi-square test and logistic regression analysis were conducted to identify the correlates of anaemia.

RESULTS

The overall prevalence of postpartum anaemia was found to be 21.6% (83). Correlates of anaemia were found to be multiple birth (AOR = 4.97), consumption of pulses (AOR = 2.07), normal BMI (AOR = 2.28) and perception of insufficient milk supply (AOR = 3.05).

CONCLUSION

The prevalence of postpartum anaemia found in this study is high. Iron and folic acid supplementation, promotion of dietary diversification practices and screening women higher risk for anaemia may be feasible interventions.

Differential effects of socio-demographic factors on maternal haemoglobin concentration in three sub-Saharan African Countries

Low Haemoglobin concentration (Hb) among women of reproductive age is a severe public health problem in sub-Saharan Africa. This study investigated the effects of putative socio-demographic factors on maternal Hb at different points of the conditional distribution of Hb concentration. We utilised quantile regression to analyse the Demographic and Health Surveys data from Ghana, Democratic Republic of the Congo (DRC) and Mozambique. In Ghana, maternal schooling had a positive effect on Hb of mothers in the 5th and 10th quantiles. A one-year increase in education was associated with an increase in Hb across all quantiles in Mozambique. Conversely, a year increase in schooling was associated with a decrease in Hb of mothers in the three upper quantiles in DRC. A unit change in body mass index had a positive effect on Hb of mothers in the 5th, 10th, 50th and 90th, and 5th to 50th quantiles in Ghana and Mozambique, respectively. We observed differential effects of breastfeeding on maternal Hb across all quantiles in the three countries. The effects of socio-demographic factors on maternal Hb vary at the various points of its distribution. Interventions to address maternal anaemia should take these variations into account to identify the most vulnerable groups.

Proportion of Immediate Postpartum Anaemia and Associated Factors among Postnatal Mothers in Northwest Ethiopia: A Cross-Sectional Study

Background

Anaemia is a major global health problem, especially in developing countries. Postpartum anaemia hurts both maternal and newborn baby health. Anaemia in pregnancy is sufficiently emphasized; however, very little attention has been paid to postpartum anaemia in Ethiopia. Therefore, this study aimed to investigate the proportion of immediate postpartum anaemia and associated factors among postpartum mothers in Debre Markos Referral Hospital.

Methods

Institutional-based cross-sectional study was conducted among 424 study participants from August 1^st to October 30^th, 2019. A systematic random sampling technique was employed to select the study participants. Data were collected through both face-to-face interview and maternal chart review by using a pretested questionnaire. Data were cleaned, coded, and entered using Epi Data version 4.6.0.0 and then exported to SPSS version 24 for analysis. First, binary logistic regression was applied to identify candidate variables for multivariable regression. Then, variables at p value <0.2 were entered into a multivariable logistic regression to control possible confounders. Finally, variables at p value <0.05 were considered as statistically significant.

Results

The proportion of immediate postpartum anaemia was 24.3%. Frequency of antenatal care (ANC) visits <4 times [AOR = 2.40; 95% CI (1.29, 4.43)], antepartum haemorrhage (APH) [AOR = 5.08; 95% CI (1.91, 13.55)], postpartum haemorrhage (PPH) [AOR = 4.47; 95% CI (2.25, 8.88)], giving birth assisted by instruments (vacuum or forceps) [AOR = 3.99; 95% CI (1.42, 11.23)], poor adherence to iron and folic acid (IFA) [AOR = 2.52; 95% CI (1.06, 6.04)], and midupper arm circumference (MUAC) <23 cm [AOR = 3.25; 95% CI (1.87, 5.65)] were the predictors.

Conclusion

The proportion of immediate postpartum anaemia was a moderate public health concern. ANC, APH, PPH, mode of delivery, adherence to IFA supplementation, and MUAC measurement were the factors affecting the magnitude of anaemia. Therefore, interventions that would address the above mentioned factors need to be implemented.

Rate and predictors of low serum ferritin levels among healthy parturient women in Enugu, Nigeria

Background

Low serum ferritin levels signify low iron stores and this could predispose to iron deficiency anemia.

Objective

To determine the rate and predictors of low serum ferritin levels during the puerperium in Enugu, Southeast Nigeria.

Study design

A hospital-based prospective longitudinal study involving parturient women who delivered singleton fetuses at term. Venous blood samples were collected to determine the serum ferritin concentration at 48 hours and 6 weeks postpartum. Data analysis involved descriptive and inferential statistics at 95% confidence interval (CI) using Statistical Package for Social Sciences (SPSS) computer software version 20.0.

Results

Two-hundred and two women who carried singleton pregnancies to term were studied. The mean serum ferritin levels at 48 hours and 6 weeks were 27.82±18.41 µg/L and 36.12±21.53 µg/L, respectively. Forty-eight hours postdelivery, 29.2% had low ferritin levels and this decreased to 12.4% at 6 weeks postpartum. There was a significant positive correlation between the serum ferritin level at 48 hours postdelivery and the serum ferritin level at 6 weeks postpartum (r=0.89, P<0.001). Predictors of the low ferritin level at 6 weeks included age <20 years (odds ratio [OR] =0.70, 95% CI =0.53, 0.93), multiparity (OR =63.7, 95% CI =3.18, 127.5), anemia at 48 hours postpartum (OR =61.7, 95% CI =13.27, 116.6), a low ferritin level at 48 hours (OR =78.1, 95% CI =8.8, 108.3), and intake of antenatal hematinics for <3 months (OR =0.04, 95% CI =0.01, 0.20).

Conclusion

There was a significant occurrence of low ferritin levels during the puerperium in the study centers, and this was associated mainly with pregnancy and delivery factors. Efforts to improve the iron stores in parturient women could benefit from early booking and compliance with antenatal hematinics and optimizing hemoglobin and iron levels before delivery.
