Anaemia affects more than half of pregnant women in rural Northern Ghana ANC clinics
Anaemia was common among pregnant women attending antenatal care in Sawla-Tuna-Kalba district, where a facility-based cross-sectional study found a prevalence of 52.2% across three health facilities. In practical terms, more than one in two women in this clinic sample met the World Health Organization’s trimester-specific definition of anaemia in pregnancy. The finding is clinically important because anaemia during gestation can reduce maternal functional reserve, worsen fatigue, and increase vulnerability to perinatal complications in settings where nutritional stress and access barriers already shape pregnancy outcomes.
The study enrolled 410 pregnant women through multistage simple random sampling and used venous blood samples analyzed on an automated hematology analyzer. Interviews captured participant characteristics, and standard statistical testing identified factors associated with anaemia. The design does not establish cause and effect, but it does give a direct look at what is happening inside routine antenatal care in a rural district of Ghana where facility-level evidence had been limited.
One result stood out sharply. Women who started antenatal care in the second trimester had more than twice the odds of anaemia compared with those who began in the first trimester.
Later antenatal booking tracked with higher anaemia odds
The association between delayed ANC initiation and anaemia fits clinical logic. Early antenatal contact creates a window for haemoglobin screening, dietary counselling, iron supplementation where indicated, malaria prevention strategies, deworming where appropriate, and repeat follow-up before haemoglobin depletion deepens. When that first encounter slips into the second trimester, the chance to detect and correct nutritional shortfalls narrows, especially if dietary intake has already been inadequate or if intercurrent infection or blood loss has contributed to declining haemoglobin levels.
In the multivariable model, second-trimester initiation of ANC carried an adjusted odds ratio of 2.11, with a 95% confidence interval of 1.11–4.01. That interval excludes unity, so the association persisted after adjustment for other measured variables. The bedside implication is straightforward: women who delay their first visit may arrive after anaemia has already developed, making early registration more than an administrative metric. It becomes a preventive intervention.
Education also mattered. Women with junior high or middle-level education had lower odds of anaemia than women with no formal education, with an adjusted odds ratio of 0.41 and a 95% confidence interval of 0.21–0.80. Higher educational attainment may improve health literacy, diet selection, confidence in navigating care, and timely uptake of preventive services. Education may also shape household decision-making and income-generating opportunities, both of which can influence maternal nutrition and access to care during pregnancy.
Education and antenatal timing shaped risk more than diet diversity in this sample
Dietary diversity was assessed, but it was not significantly associated with anaemia in the adjusted model. Other measured variables also failed to reach statistical significance. That does not mean nutrition is irrelevant. Rather, it suggests that within this sample and analytic framework, the variation captured by the study was not enough to show a clear independent link once other factors were considered. Dietary diversity questionnaires can also miss the full biological reality of iron intake, absorption, parasite exposure, inflammation, and the cumulative effects of repeated pregnancies or short interpregnancy intervals.
The most sobering aspect of the data is the scale of the prevalence itself. A 52.2% burden places anaemia in the category of a major maternal health problem, not a marginal laboratory abnormality. In pregnancy, reduced oxygen-carrying capacity can compound the physiologic demands of expanded plasma volume and fetal growth. In regions where food insecurity, infection, and limited access to early screening overlap, haemoglobin decline can become part of the routine antenatal picture unless services intercept it early.
Why these findings matter for rural antenatal care delivery
This study points toward two actionable levers: earlier booking and better counselling. Clinicians and community health workers do not need to wait for large policy shifts to act on either. Encouraging women to attend ANC in the first trimester creates earlier opportunities for haemoglobin assessment and prevention counseling. Pairing that message with targeted education may be especially valuable for women with no formal schooling, who in this cohort carried higher odds of anaemia than those with more education.
The facility-based setting should also temper interpretation. The women came from three health facilities in one district, so the sample cannot be assumed to represent every pregnant woman in the wider region. Cross-sectional measurement captures one point in time and cannot determine whether delayed ANC caused anaemia or whether women with unrecognized health problems were more likely to present later. Even so, the pattern is clinically coherent and supports interventions that are already low-risk and inexpensive: earlier antenatal contact, haemoglobin screening, and counselling focused on anaemia prevention.
The authors obtained ethical approval from the Institutional Review Board of the University of Business and Integrated Development Studies, and participants provided informed consent. No specific grant supported the work, and the investigators declared no competing interests. Those details do not change the haemoglobin results, but they do frame a study carried out with standard ethical safeguards and without apparent commercial influence.
For rural antenatal services, the message is immediate and concrete. Anaemia is common, and first-trimester engagement may be one of the simplest ways to reduce the burden before haemoglobin levels fall further and pregnancy risks accumulate.
