ABSTRACT

Background

In Sub‐Saharan Africa, anemia is a significant public health issue, affecting individuals of all ages. While prevention efforts focus on infants, children, and pregnant women, adolescents are overlooked often, leading to ongoing challenges. Despite its prevalence, there is a paucity of research on anemia in adults, particularly university students in Ghana. Studying this demographic can improve understanding and inform public health interventions, addressing the unique needs of university populations and ultimately reducing the burden of anemia.

Aim

The aim of this research was to assess the knowledge, attitudes, and practices of newly admitted university students regarding the importance of vitamins in blood formation, renewal, and function. This study targeted newly admitted university students, as they represent a transitional group from adolescence to young adulthood, often experiencing changes in dietary patterns, living arrangements, and lifestyle that may predispose them to nutritional deficiencies and anemia.

Methodology

This study employed a cross‐sectional design, utilizing both quantitative and qualitative data collection methods. About 300 newly admitted students undergoing routine medical screening at the University Hospital were recruited. Data regarding the knowledge, attitude and practices, as well as misconceptions of participants were obtained using a structured questionnaire, whereas clinical data were obtained from their medical records.

Results

Among the 300 participants, anemia prevalence was 40.0%, with 45.3% demonstrating good knowledge and 50.7% positive attitudes and practices. Knowledge differed significantly by program of study (p = 0.03), while misconceptions such as believing that ‘men by default have higher vitamin needs’ were strongly associated with anemia (aOR = 2.29, p = 0.022).

Conclusion

While nearly half demonstrated good knowledge and positive attitudes and practices, misconceptions, particularly gender‐based beliefs, significantly increased anemia risk. These findings emphasize the need for targeted, campus‐based nutrition education that not only improves knowledge but also actively corrects misconceptions to reduce anemia burden.

1. Introduction

Across the globe, it was estimated that an alarming proportion exceeding 30% of the entire population had encountered anemia, with statistics indicating that more than 80% of the overall burden attributable to this health issue was predominantly concentrated within developing nations Benfo et al., [1]. In numerous countries situated within Sub‐Saharan Africa, anemia was recognized as a critical public health concern, manifesting in varying degrees of severity, ranging from moderate to severe levels, highlighting the gravity of this situation [2]. Anemia in university students is of particular concern as it can impair cognitive function, reduce academic performance, and increase fatigue, thereby affecting educational outcomes.

The adverse health consequences stemming from anemia affected individuals across a wide spectrum of age groups and were traced back to a complex interplay of both nutritional and non‐nutritional determinants [3]. The high rates of nutritional lacks, especially regarding essential micronutrients like iron, vitamin B12, and folate, are key factors in the global prevalence of anemia [4, 5, 6].

Preventive measures aimed at reducing the incidence of anemia predominantly focused on vulnerable populations, specifically infants, young children, and pregnant or lactating women, often neglecting the critical demographic of adolescents [7, 8]. As a result, the ongoing repercussions of anemia within the adolescent population continue to pose substantial challenges [9].

The multifaceted and significant roles played by essential vitamins, including their contributions to blood cell formation and their regulatory functions in metabolism, emphasized the urgent necessity for a comprehensive and thorough investigation into their biological effects and implications Saghiri et al., [10]. Deficiencies in vitamins such as B6, B12, folate, and vitamin C impair hemoglobin synthesis and red blood cell production, making them major contributors to anemia Stabler [11].

Ghana stood out as a country facing numerous formidable issues linked to undernutrition, micronutrients deficiencies, creating a serious public health predicament. On a global scale, Ghana was positioned at a concerning 135th place out of 187 countries that exhibited the highest burden of malnutrition Tandoh et al., [12]. A recent cohort in Cape Coast found that anemia prevalence among university students increased from 20% to over 40% within one academic year, largely due to nutritional deficiencies. This troubling occurrence was linked to a lack of sufficient intake of important nutrients such as vitamin C and folate [13].

Recent studies highlight concerning health issues among young individuals, with anemia rates reaching 72.5% and vitamin A deficiency at 35.6%, signaling a pressing public health challenge Egbi [14]. Additionally, research indicates that many university students lack adequate knowledge of essential vitamins, often self‐prescribing supplements without professional guidance, which raises concerns about their understanding of safe vitamin use [15]. Genç et al. [16]. While some recognize the importance of dietary supplements, a significant number self‐prescribe without professional guidance, exposing a gap in their knowledge of safe vitamin use Sekhri, Kaur [17].

Despite satisfactory awareness of certain vitamins, students often exhibit poor dietary attitudes, such as neglecting sun exposure for vitamin D synthesis. This inconsistency highlights the need for well‐structured educational strategies to enhance understanding of vitamins' roles in blood formation and overall health [18].

There is a notable research gap in assessing the knowledge, attitudes, and practices (KAP) of new university students regarding vitamins. Understanding their KAP can pinpoint areas needing intervention, promoting better health education and preventing deficiencies. This study fills a critical gap by evaluating the knowledge, attitudes, practices, and misconceptions of newly admitted university students on vitamins, with the broader implication of informing targeted interventions to prevent anemia in higher education institutions, and contributing to Sustainable Development Goal 3; ensuring good health and well‐being.

2. Materials and Methods

2.1. Study Design

The study was conducted from September 2024 to December 2024 during routine medical screenings. This study employed a cross‐sectional design, which exploited both quantitative and qualitative data collection methods to gain a comprehensive understanding of the KAP of newly admitted university students.

2.2. Research Study Site

The research was conducted at the University of Cape Coast Hospital, which targeted newly admitted students across various disciplines. University of Cape Coast Hospital is situated at the central region of Ghana, Cape Coast. The University of Cape Coast Hospital is one of the renowned hospitals in the Central Region of Ghana, which provides services like Out‐Patient, In‐patient, Obstetric and Gynecological, Family Medicine, Specialist Services (Dental, Ear and Throat, Eye and Physiotherapy), Diagnostic Services (Laboratory, X‐Ray, ECG, Ultrasound Scan), Pharmaceutical Services, Counseling Services (HIV/AIDS, Family and Psycho‐social), Reproductive, Child‐Health and Family Planning and Mortuary Services.

The University Hospital is also tasked with the annual medical screening of newly admitted university students before their matriculation and commencement of the academic year. Therefore, consented newly admitted undergraduate students undergoing their routine medical screening were targeted and enrolled into the study.

2.3. Sample Size

A convenient sampling method was used to ensure representation from different faculties or colleges within the university.

The sample size was estimated using the Slovin's formula n =N[1+Ne2] [19].

Where “n” is the number of samples, “N” is the total population, and “e” is error of tolerance (5%). Using the number of newly admitted undergraduate students for 2023/2024 academic year, 9059. The number of samples, n = 9059/[1 + 9059 (0.052)] is 383, however, 300 students voluntarily consented.

2.4. Selection of Participants

A convenient sampling method was used to select consented prospective participants for this study. This approach was used to ensure diversity in academic backgrounds, which helps improve representativeness despite the non‐random nature of the sampling [20]. All consented newly admitted students who visited the University of Cape Coast Hospital for their medical screening were recruited into the study. In all, 300 newly admitted undergraduate students were enrolled in the current study. The participants had generally gained admission to pursue a wide range of undergraduate programs that were either health‐related or non‐health related.

2.5. Inclusion and Exclusion Criteria

Participants included newly admitted undergraduate students at the University of Cape Coast who completed their routine medical screening and voluntarily consented to participate. Postgraduate students, students enrolled in distance learning programs, and others with chronic conditions such sickle cell disease that have been diagnosed and may impact hemoglobin levels were all excluded.

2.6. Data Collection

2.6.1. Questionnaire Administration

Closed‐ended structured questionnaires, adopted with slight modifications from previous studies [21, 22, 23], were given to the individual participants. The questionnaire assessed the knowledge, attitude and practices of students on vitamins that are crucial for blood formation, renewal and function, as well as some misconceptions about these vitamins. The questionnaire, adapted from Parmenter & Wardle [24], included 12 knowledge items, 8 attitude items, and 6 practice items [24]. Reliability was confirmed in a pilot test of 30 students (Cronbach's α = 0.78 for knowledge, 0.74 for attitude, 0.81 for practice). The questionnaire was written in a relatively simple and plain English Language which was devoid of technical terminologies or jargons.

2.7. Anthropometric and Clinical Data Collection

Participants' anthropometrics including weight (kg) and height (cm), blood pressure, pulse rate as well as laboratory data on anemia and associated risk factors including hemoglobin level, sickling status, proteinuria, haemoglobinuria and hematuria were obtained from the students' medical records.

2.8. Ethical Consideration

Before this study was conducted, ethical approval was sought from the Institution Review Board (IRB) of the University of Cape Coast; Ethical Clearance ID (UCCIRB/CHAS/2024/111). Informed consent was obtained from prospective participants before enrolled into the study. Likewise, the participants were at liberty to withdraw from the study at any given time. All procedures undertaken were in conformity with the declaration of Helsinki.

2.9. Statistical Analysis

All the data were recorded manually in Microsoft Office Excel. For data processing and management, we used the Statistical Package for Social Sciences (SPSS) version 26 (IBM Inco., USA). Quantitative variables were tested for normality using the Shapiro‐Wilk test and presented as median (interquartile range). Qualitative variables were presented as frequencies and percentages. Also, descriptive statistics, Chi square test, Fisher's Exact test, and binary logistic regression analyzes were used to explore the data. Anemia was defined by hemoglobin levels < 12.5 g/dl and < 11.5 g/dl in males and females respectively, according to established guidelines [25]. Statistical significance was established at p < 0.05 at 95% confidence interval.

Knowledge score criteria of “I know,” “I have no idea,” and “I do not know” were used to grade the participants' knowledge regarding vitamins and blood formation. A participant was said to have knowledge of a question if they were able to give a correct answer to the question. The overall knowledge performance of the participants was computed by treating the knowledge responses as a continuous variable. Each correct response to a question was awarded a point, and the total sum of correct responses was found. The 33rd and 67th percentiles were calculated as 5 and 8, respectively. Participants that scored between 0 and 5 were classified as having “low knowledge,” those that scored between 5 and 8 were classified as having “moderate knowledge” and those with a value higher than 8 were classified as having “high knowledge.”

2.10. Dependent and Independent Variables

Anemia status, which was classified as present (1) or absent (0) depending on the subjects' hemoglobin levels, was the study's dependent variable. Among the independent variables were common vitamin misunderstandings and knowledge, attitudes, and practices (KAP) about vitamins related to blood formation, renewal, and function. A structured questionnaire was used to assess knowledge, and answers were divided into three categories: I agree, I have no idea, and I disagree. Attitudes and practices were measured based on dietary habits, supplement use, and consultation with healthcare providers. Misconceptions were assessed using Yes/No responses. Additional independent variables included age, sex, program of study, and parental profession.

2.11. Measurement Tools and Questionnaire Construction

The questionnaire used in this study was adapted from previous validated research.

2.12. Cutoff Points for Knowledge, Attitude, and Practice (KAP) Scores

A composite knowledge score was calculated by assigning 1 point for each correct response and 0 for incorrect or “no idea” responses. The total knowledge score ranged from 0 to 12, with knowledge levels categorized using mean value: Poor (< 5), and Good (≥ 5). Attitude and practice scores were similarly categorized based on responses to Likert‐scale items, where a score of < 4 was Poor attitude, and a score ≥ 4 was Good attitude. These cutoff points align with established methods for knowledge classification in health research [26, 27, 28].

2.13. Binary Logistic Regression

Binary logistic regression was used to assess associations between sociodemographic variables and three outcomes: knowledge level, misconceptions about anemia, and anemia prevalence. Sociodemographic variables were included because they are recognized determinants of anemia and may confound these relationships; for example, sex is a biological determinant [29], program of study reflects health literacy differences [30], and parent's profession is a proxy for socioeconomic status affecting diet and healthcare access [31]. History of transfusion and vitamin supplement intake were also included as clinical factors that may independently influence anemia status. Marital status and history of pregnancy (if female) were excluded due to low counts that could have yielded unstable estimates. Adjusted odds ratios (aOR) with 95% confidence intervals (CI) were reported to estimate the strength and direction of associations.

2.14. Anemia Classification

Anemia was classified according to World Health Organization (WHO) guidelines, with hemoglobin concentrations < 12 g/dL for women and < 13 g/dL for men considered anemic [32].

3. Results

3.1. Socio‐Demographics and Clinical Characteristics of the Study Participants

Among the 300 participants, females were slightly more represented (164/300, 54.7%) than males (Table 1). The majority were aged 20–30 years (159/300, 53.0%). Anemia was present in 120/300 (40.0%, 95% CI: 0.54–0.66). Approximately 42% had elevated systolic pressure and 31% had elevated diastolic pressure. Notably, 36/300 (12.0%) had sickling trait.

3.9. Misconceptions About Vitamins and Anemia

Misconceptions were widespread (Table 9): 250/300 (83.3%) believed that “the more vitamins, the better,” and 229/300 (76.3%) thought vitamins directly provide energy. Importantly, the belief that ‘men have higher vitamin needs than women' was significantly associated with anemia (aOR 2.29, 95% CI: 1.13–4.66, p = 0.02). Other misconceptions, including ‘only vegetarians are at risk of deficiency’, were not significant.

4. Discussion

In this study of newly admitted university students, we found an anemia prevalence of 40.0%, with 45.3% demonstrating good knowledge of the role of vitamins in blood metabolism and 50.7% showing positive attitudes and practices. Knowledge significantly differed by program of study (p = 0.03), while misconceptions such as the belief that “men by default have higher vitamin needs” were significantly associated with anemia (AOR = 2.29, p = 0.022). These findings have several implications for nutrition education and public health practice.

4.1. Prevalence of Anemia and Knowledge, Attitudes, and Practices (KAP)

The prevalence of anemia (40.0%) among newly admitted students is substantial, indicating a persistent burden in this population. This finding is consistent with a repeated‐measure study among tertiary students in Cape Coast, Ghana, where anemia prevalence more than doubled over the academic year, rising from 20% at entry to nearly 45% by the end [25]. The similarity in magnitude suggests that university students are already vulnerable at admission and may remain at risk throughout their academic years.

Our results also show that although 45.3% of participants demonstrated good knowledge and about half (50.7%) reported positive attitudes and practices, a significant proportion lacked adequate awareness or failed to translate knowledge into healthy behaviors. This mirrors findings from Ghanaian adolescents, where awareness of iron deficiency existed but dietary diversity and intake of iron‐rich foods remained poor Appiah et al., [33]. Such patterns highlight that knowledge alone is insufficient to prevent anemia. The behavioral reinforcement, supportive food environments, and targeted interventions are also necessary.

Interventions should not only aim to improve knowledge but also emphasize behavior change through structural support. Nutrition education could be integrated into secondary and tertiary curricula to establish good practices early, while campus‐based programs could promote access to vitamin‐ and iron‐rich foods. Screening and counseling during student health registrations may also help to identify at‐risk students before anemia worsens.

4.2. Role of Misconceptions and Sociodemographic Associations

One of the most important findings of this study is the association between misconceptions and anemia. Students who believed that “men inherently require higher vitamin intake” had more than twice the odds of being anemic. This suggests that even when general knowledge is moderate, entrenched misbeliefs can override correct understanding and lead to harmful practices. Similar observations have been reported in Ghana, where cultural perceptions of anemia often diverge from biomedical explanations and may shape dietary choices Awuah et al., [34].

We also observed that knowledge varied significantly by program of study (p = 0.03), with students enrolled in health‐related programs scoring better than their peers. This confirms prior findings that academic exposure influences nutrition literacy (Bawazir, Alrasheedi and Aljehany; Alghamdi et al., [35]). However, the persistence of misconceptions across both groups suggests that formal education alone is insufficient to prevent misinformation.

Targeted myth‐busting interventions are important. Public health campaigns for students should explicitly address common misconceptions, particularly gender‐related beliefs, rather than relying solely on factual instruction. Tailored messaging, informed by formative qualitative research, may be more effective in reshaping attitudes and behaviors. Additionally, interventions could be stratified by program of study, with non‐health‐related students receiving more foundational content.

5. Conclusion

This study identified a high prevalence of anemia (40.0%) among newly admitted university students. Although nearly half of participants demonstrated good knowledge (45.3%) and positive attitudes and practices (50.7%), misconceptions, particularly gender‐related beliefs were strongly associated with anemia risk. Knowledge also varied by program of study, with health‐related students performing better, yet misconceptions persisted across groups.

These findings highlight that nutrition interventions in universities must go beyond disseminating factual knowledge. Effective strategies should directly address widespread misconceptions, integrate nutrition education into secondary and tertiary curricula, and ensure supportive food environments that enable healthy practices. Screening at admission and campus‐based counseling may further help reduce anemia burden.

Future research should adopt longitudinal designs to track how student behaviors and nutritional status evolve during university years, and evaluate the impact of tailored interventions, including myth‐busting campaigns and dietary programs on reducing anemia prevalence.

6. Limitations

It is vital to acknowledge that the study was conducted at only one location, which raises valid concerns about how broadly the outcomes can be extended to different university demographics that could be diverse in multiple socio‐cultural and demographic factors.

The cross‐sectional approach utilized in this study greatly limits the capacity to definitively determine a causal connection between students' knowledge, attitudes, and practices (KAP) and their related health outcomes, especially concerning the incidence of anemia within the examined group.

Utilizing convenience sampling in this research, while undoubtedly advantageous, could unintentionally lead to some bias, as this method might not fully encompass the rich diversity and variety of the larger student demographic found in the overall educational landscape.

Furthermore, the reliance on self‐reported data for the assessment of knowledge, attitudes, and practices introduces the potential for social desirability bias, wherein participants may feel compelled to overstate their levels of knowledge or to underreport behaviors that are deemed undesirable or socially unacceptable.

7. Recommendations

To address knowledge gaps among new university undergraduates about vitamins and their role in blood health, several recommendations are proposed. These include integrating nutrition education into all curricula, with a focus on vitamins and their dietary sources, and creating targeted interventions for high‐risk groups like female students to address specific nutrient needs.

Evidence‐based health campaigns should dispel misconceptions, and universities should improve access to affordable vitamin supplements. Parental involvement in health education is encouraged, alongside regular anemia screening and monitoring. Finally, future research should assess the long‐term impact of these health interventions on students' knowledge and outcomes.
