Prevalence, Severity, and Correlates of Anaemia in Pregnancy among Antenatal Attendees in Warri, South-Southern Nigeria: A Cross-Sectional and Hospital-Based Study

Food-based domestic violence and anemia among women in sexual unions in Nigeria: the effect of urbanization

In 2019, 1.74 billion people worldwide had anemia. In Nigeria, women of reproductive age are the most affected. Domestic violence affects the anemia prevalence, but few studies have examined the influence of urbanization on women in heterosexual unions (currently married, and cohabiting between). Using the social determinants of health framework, we argue that food-based violence and anemia vary among women residing in rural and urban areas. We used the Chi-square test and logistic regression to analyze the 2018 Nigeria Demographic and Health Survey records (n = 10,499). The study showed that anemia occurs more among women in rural (66%) than in urban (34%) areas. In rural areas, anemia was 29% higher among women who approved food-based domestic violence (OR: 1.29, CI 1.15-1.57) than those who did not. In urban areas, food-based domestic violence was not significantly associated with anemia. This study emphasizes the urgent need for culturally sensitive maternal health interventions aimed at re-orienting individuals and families on violence in rural areas.

Ecological analysis of demographic-, nutritional- and housing-related factors associated with anaemia among women of reproductive age group in Nigeria

INTRODUCTION

Anaemia remains a major public health concern, particularly, in sub-Saharan Africa (SSA), where it is one of the causes of maternal death. The most common cause of maternal anaemia is iron deficiency or malnutrition. This study examined the prevalence of and risk factors for anaemia among women that participated in the Nigerian Demographic Health Survey.

METHOD

We used data of 14,454 women that participated in the 2018 Nigeria Demographic and Health Survey (NDHS). We extracted information such as demographic, social and housing, dietary characteristics and haemoglobin concentration. The descriptive statistic results, prevalence and 95% confidence interval (CIs) of anaemia with the selected respondents background characteristics were presented. The Poisson regression model with robust variance was used to assess the risk of anaemia among women of reproductive age. All analyses were weighted and adjusted for the complex survey design. Statistical significance was interpreted at p value < 0.05.

RESULTS

Maternal status, body mass index, education, residence, religion, ethnicity, region and type of cooking fuel were all important determinants of anaemia. The prevalence of anaemia was high among pregnant women (61.8%; 95% CI: 58.5-65.0), adolescents (60.4%; 95% CI: 58.1-62.6), underweight women (62.6%; 95% CI: 59.5-65.5), women who had no formal education (64.1%; 95% CI: 62.2-66.0) and those who belonged to the poorest wealth quintile (65.8%; 95% CI: 63.1-68.4). Similarly, anaemia was high among women residing in rural areas (61.5%; 95% CI: 60.0-63.0), Muslims (59.9%; 95% CI: 58.1-61.6) and women with six or more children (62.1%; 95% CI: 60.0-64.1). The risk of anaemia were 2% less likely among women who took minimum adequate diet compared to those who do not.

CONCLUSION

To date, this is the largest data on maternal anaemia in Nigeria. The study highlighted the high burden of maternal anaemia in the country and different risk factors (medical and social) that are associated with this medical condition among women of reproductive age. We recommend future longitudinal studies to test hypothesis in order to assess whether there is any causal relationship between identified risk factors and anaemia in this group of women.

Intravenous versus oral iron for iron deficiency anaemia in pregnant Nigerian women (IVON): study protocol for a randomised hybrid effectiveness-implementation trial

Background

Anaemia in pregnancy is highly prevalent in African countries. High-dose oral iron is the current recommended treatment for pregnancy-related iron deficiency anaemia (IDA) in Nigeria and other African countries. This oral regimen is often poorly tolerated and has several side effects. Parenteral iron preparations are now available for the treatment of IDA in pregnancy but not widely used in Africa.

The IVON trial is investigating the comparative effectiveness and safety of intravenous ferric carboxymaltose versus oral ferrous sulphate standard-of-care for pregnancy-related IDA in Nigeria. We will also measure the implementation outcomes of acceptability, feasibility, fidelity, and cost-effectiveness for intravenous ferric carboxymaltose.

Methods

This is an open-label randomised controlled trial with a hybrid type 1 effectiveness-implementation design, conducted at 10 health facilities in Kano (Northern) and Lagos (Southern) states in Nigeria. A total of 1056 pregnant women at 20–32 weeks’ gestational age with moderate or severe anaemia (Hb < 10g/dl) will be randomised 1:1 into two groups. The interventional treatment is one 1000-mg dose of intravenous ferric carboxymaltose at enrolment; the control treatment is thrice daily oral ferrous sulphate (195 mg elemental iron daily), from enrolment till 6 weeks postpartum.

Primary outcome measures are (1) the prevalence of maternal anaemia at 36 weeks and (2) infant preterm birth (<37 weeks’ gestation) and will be analysed by intention-to-treat. Maternal full blood count and iron panel will be assayed at 4 weeks post-enrolment, 36 weeks’ gestation, delivery, and 6 weeks postpartum. Implementation outcomes of acceptability, feasibility, fidelity, and cost will be assessed with structured questionnaires, key informant interviews, and focus group discussions.

Discussion

The IVON trial could provide both effectiveness and implementation evidence to guide policy for integration and uptake of intravenous iron for treating anaemia in pregnancy in Nigeria and similar resource-limited, high-burden settings. If found effective, further studies exploring different intravenous iron doses are planned.

Prevalence and associated risk factors for anaemia amongst pregnant women attending three antenatal clinics in Eswatini

BACKGROUND

 Anaemia is a global health problem affecting about a third of the world's population. In pregnancy, it is a public health concern with consequences for mothers and infants, including maternal death and infant mortality. In low-income countries (LICs), 25% indirect maternal mortality and 30% neonatal deaths are due to anaemia in pregnancy.

AIM

 This study aimed to determine the prevalence and risks associated with anaemia amongst pregnant women attending antenatal clinic (ANC) in three health facilities in Eswatini.

SETTING

 This study was conducted in three health facilities in Eswatini, namely Mankayane, Raleigh Fitkin Memorial (RFM) and Mbabane Hospital.

METHODS

 This cross-sectional study used non-probability sampling in three hospitals of Eswatini, to select 550 pregnant women, aged 15-49 years. Data were collected from January to March 2021, using face-to-face interviews with a structured questionnaire. Logistic regression was used for statistical analysis.

RESULTS

 A total of 550 pregnant women were included in the study. Anaemia prevalence amongst pregnant women was 43.1% with mild, moderate and severe cases of 21.3%; 21.1% and 0.7%, respectively. Prevalence was high amongst women aged 15-19 years (53.3%). Factors associated with anaemia included living in urban areas (odds ratio [OR]: 1.8; confidence interval [CI]: 1.19-2.72), having anaemia 6 months before pregnancy (OR: 4.64; CI: 1.15-18.71), and gestational age at first ANC: third trimester (OR = 10.42; CI: 4.27-25.4) and second trimester (OR: 1.62; CI: 1.02-2.60).

CONCLUSION

 Anaemia remains prevalent amongst pregnant women in Eswatini. A comprehensive anaemia prevention programme would be justified and could lower the country's burden of anaemia.

A study on anemia and its risk factors among pregnant women attending antenatal clinic of a rural medical college of West Bengal

BACKGROUND

Anemia is the commonest nutritional deficiency disorder in the world, particularly in developing countries. Though anemia is easily treatable and largely preventable disease if timely detected, it still continues to be significantly prevalent among pregnant women.

AIM

The aim of this study was to measure the extent of anemia in pregnancy and to assess the association of risk factors with anemia.

STUDY DESIGN

Hospital-based cross-sectional descriptive study.

MATERIALS AND METHODS

A total of 200 women were selected among pregnant women attending antenatal clinic. Sampling was done by selecting every fifth woman visiting antenatal clinic within the duration of two months on alternate days. Data were collected using a predesigned, pretested semi-structured schedule. Hemoglobin concentrations were also recorded for each patient. Data were analyzed using Chi-square test and 'T' test of significance. A value of P < 0.05 was considered significant.

RESULTS

We found overall prevalence of anemia to be 90% among pregnant women. Most of the anemic patients (60.5%) belong to moderate severity according to the World Health Organization classification. Three factors namely socioeconomic status, gravida and time of 1st antenatal visit were significantly associated with prevalence of anemia in pregnancy (P < 0.05).

CONCLUSION

In this study, a high prevalence of anemia was found in pregnant women. Low socioeconomic status, multigravida and delayed visit to antenatal clinic were significantly associated with anemia in pregnancy. So, awareness and education programs should be generated to make people come to know about anemia, its complications during pregnancy and ways to prevent it.

Proportion of anaemia and factors associated with it among the attendees of the antenatal clinic in a teaching institute of northeast India

BACKGROUND

Anaemia is an important cause of maternal morbidity and mortality in India. According to National Family Health Survey-4, the prevalence of anaemia among pregnant women in Tripura was 54.4%, but the proportion of anaemic women attending antenatal clinics is not known.

OBJECTIVES

To find out the proportion of anaemia and associated factors among pregnant women attending antenatal clinic at Agartala Government Medical College.

MATERIALS AND METHOD

This hospital-based cross-sectional study was conducted among 200 pregnant women attending the antenatal clinic of Agartala Government Medical College from 14th July to 7th August 2019 chosen by consecutive sampling.

RESULTS

Majority (69.5%) of the women were aged either ≤ 25 years, 94.5% were Hindu, 37% belonged to scheduled caste community, 58.5% from a rural area, 28% belonged to BG Prasad's class II socioeconomic status and 52.5% had only primary education. The proportion of anaemia was found to be 60%. It was 63.3% among ≤ 25 years age group and 62.9% among those who studied up to primary level. Mean (SD) Hb level was 9.9 ± 0.6 g%. Among the anaemic, 57.5% were primigravida and 45% were carrying the third trimester of pregnancy. Only 1% of the study women reportedly consumed either 200 or more number of iron tablets. Age < 25 years, (OR = 1.824, 95% CI = 1.231-2.108, P = 0.003), holding BPL or similar ration cards (OR = 3.482, 95% CI = 1.201-5.371, P = 0.031) and getting at <18 years (OR = 4.482, 95% CI = 2.317-6.451, P = 0.003) were identified as the significant predictors of anaemia during pregnancy.

CONCLUSION

The proportion of anaemia among attendees of the antenatal clinic was higher than the state prevalence of anaemia among pregnant women. Lower literacy, lower socioeconomic status, rural residence, etc., had significant associations with anaemia in this population.
