Introduction

There are many definitions of health literacy (HL) because the concept is well known. According to the World Health Organization (WHO), it is “the cognitive and social skills that determine the motivation and ability of individuals to (access), understand, and use information in ways that promote and maintain good health” [1]. Health literacy is also known as “health consciousness”, which plays a key role in the proper management of health and disease by determining health-related decisions and thus health consequences. In view of the new concept of primary health care (PHC), which emphasizes the use of preventive tools and care coordination rather than the provision of medical services, it is reasonable to indicate that shaping patients’ HL is one of the basic needs and challenges in PHC. Health care providers should be aware of the widespread differences in patients’ health competences, which, among other issues, cause a variety of problems in health and disease management. As a result, it is of key importance to identify HL determinants so that health interventions can be better tailored to the patient and their ability to maintain good physical and mental health and prevent disease infection and spread.
It is believed that rural residents have poorer health outcomes than urban residents [2]. Polish people living in rural areas have a poorer assessment of their physical health condition [3] and are significantly less likely to care for their mental health [4]. They are unlikely to follow medical recommendations [5] and take up physical activity [6], as compared to urban residents. In terms of stimulants, rural residents are more likely to smoke cigarettes [7], whereas urban residents are more likely to drink alcohol [8]. Rural residents have a higher mortality rate, which mainly results from cardiovascular diseases, cancers, and lung diseases [2].
A variety of factors affect the differences in health condition and health behaviour between rural and urban residents. One of these factors is thought to be HL, which is of key importance for accessing, understanding, evaluating, and using health-related information within health protection, disease prevention, and general health promotion areas [9]. Several studies [10, 11] have found that rural residents have lower levels of health literacy. However, it should be noted that this trend does not apply to Poland. According to studies conducted in Poland, rural residents have slightly higher general health literacy scores than urban residents, but these differences are not statistically significant [12]. However, no studies have been conducted in Poland to evaluate specific HL determinants or differentiated health literacy levels based on the place of residence of the respondents. In contrast, only a few studies have focused on measuring overall HL in Polish society [12–15]. Therefore, the research results presented herein fill a knowledge gap in the health literacy area.

Aim of the research

The aim of this study was to determine the HL level among PHC patients depending on their place of residence. The second goal was to determine how different sociodemographic, family, and health predictors affect the HL level in the study group depending on their place of residence.

Material and methods

Study design and participants
Between January and December 2020, a cross-sectional study involving 566 patients from 4 PHC facilities located in the Lubelskie Province of eastern Poland was carried out. Health service data from the selected PHC facilities for 2019 were used for sampling. The principle of proportionality was used to select patients based on the quantity of health services provided in the year preceding the research. Efforts were made to obtain responses from 20% of all respondents in each of the 5 age groups: 18–19 years, 20–39 years, 40–65 years, 66–75 years, and older than 75 years. With a minimum sample size of 378 people (confidence interval 0.95, maximum error 5%), the resulting sample size (n = 566) was adequate for population analyses. The inclusion criteria were as follows: (1) patient’s age 18 years and above; (2) use of PHC services at one of the selected health care facilities; and (3) informed consent to participate in the study. The exclusion criteria included: (1) patient’s age below 18 years; (2) mental disorder, i.e. illness significantly affecting the state of consciousness; and (3) lack of consent to participate in the study.
Ethical approval
Participation in the study was entirely voluntary and anonymous. The study was conducted in accordance with the ethical principles of the Declaration of Helsinki and was approved by the Bioethics Committee of the Medical University of Lublin (KE-0254/83/2019).
Data collection
The data were collected through personal interviews using the paper and pencil interview (PAPI) method. Each respondent could only complete one survey questionnaire. Patients with health issues who found it difficult to complete the questionnaire on their own were allowed to be assisted by a caregiver. The survey questionnaires were collected by trained nurses during patient visits to the primary health care facilities and home visits. In each of the selected primary healthcare facilities, 2 research study notices were posted on the facility’s front door and at the registration desk. In addition, nurses informed patients about the study and distributed pre-prepared information leaflets. Survey questionnaires were distributed to patients seeking health advice at the PHC facilities on 3 pre-determined days of the week: Tuesday, Thursday, and Friday. All patients who had a nursing home visit were invited to participate in the study and were accepted if they met the inclusion criteria. As soon as the intended number of questionnaires was gathered, the collection of questionnaires at each PHC facility was completed. A total of 640 questionnaires were distributed, but 74 were rejected due to missing responses. As a result, 566 correctly completed questionnaires were analysed. The return rate was 88.4%.
Measurements
Health literacy was measured using the European Health Competence Questionnaire (HLS-EU-Q16) [16]. This survey tool contains 16 items addressing self-reported difficulties in accessing, understanding, and appraising health information related to health care, disease prevention, and health promotion). Each item was rated on a 4-point Likert scale. The total score reflects general health literacy, categorised as follows: 13–16 points – sufficient health literacy level, 9–12 points – problematic health literacy level, 0–8 points – inadequate health literacy level. The questionnaire shows evidence of adequate internal reliability and accuracy. Cronbach’s a coefficient for the entire questionnaire was 0.98 and for the individual subscales it was 0.94–0.95.
The Family APGAR Questionnaire [17] was applied for the measurement of family function. The questions in the Family APGAR Questionnaire are designed to permit qualitative measurement of a family member’s satisfaction with 5 components of family function identified as adaptation, partnership, growth, affection, and resolve. Each of the items is scored on the following scale: “always”, “almost always”, “sometimes”, “hardly ever”, and “never”. The total score reflects general family status, categorised as follows: 8–10 points as “no significant disturbances in the family system”, 4–7 points as “existence of irregularities in the family system”, and 0–3 points as “serious dysfunction in the family system”. The overall Cronbach’s a coefficient in the Polish version was 0.81.
The General Health Questionnaire (GHQ-28) [18] was used for the detection of mental disorders. The questionnaire consists of 28 items that relate to the respondent’s medical complaints over the past few weeks. This tool assesses somatic symptoms, anxiety and insomnia, social dysfunction, and severe depression. The general health condition was determined by adding points from the entire questionnaire and converting the total score (range between 0 and 84 points) into the so-called “standard ten” score, which was developed on the basis of Polish population studies [17]. Cronbach’s a coefficient for the Polish version of the questionnaire was 0.9 and 0.8–0.9 for the individual subscales.
Standard questions were employed to collect variables, such as place of residence, age, gender, marital status, education, source of income, financial situation, financial capability, number of children, and co-morbidities. In addition, the respondents were asked about their body weight and height. Based on the above data, the body mass index (BMI) was calculated as body weight (kg) divided by height squared in metres (kg/m2), and subjects were classified as normal weight when BMI = 18.5–24.9 kg/m2, overweight when BMI = 25–29.99 kg/m2, and obese when BMI ≥ 30 kg/m2 [19].
Statistical analysis
Categorical variables were reported as absolute numbers and percentages, and continuous variables were presented as means (M) with standard deviation (SD). The Shapiro-Wilk test was applied to assess conformity with a normal distribution. Differences between groups were assessed by t-test, Pearson’s c2 test, or analysis of variance (ANOVA). Simple and multiple linear regression models were performed to assess the significant predictors of HL. The IBM SPSS Statistics for Windows, Version 28.0. (Armonk, NY: IBM Corp) software was used for statistical analysis. A p-value less than 0.05 was considered significant for all tests.

Results

General characteristics of the study participants
Table 1 shows the characteristics of the study group depending on the participants’ place of residence. The mean age in the study group was 49.28 ±18.39 years. Moreover, most respondents were women (63.3%; n = 358) who lived in rural areas, (52.5%; n = 297), had secondary education (38%; n = 215), and were in a relationship (60.8%; n = 344). When compared to rural residents, urban residents were more likely to have higher education, no children, and a healthy weight according to their BMI.
The mean GHQ-28 scale score was significantly higher among urban residents (26.37 ±12.1) than among rural residents (23.99 ±10.09) (p = 0.0014). The mean HL score (HLS-EU-Q16) of urban residents was also slightly higher (12.19 ±3.5) than that of rural residents (11.91 ±4.1). After converting the data into 2 groups, 159 (52.5%) urban residents and 144 (47.5%) rural residents had sufficient level of health literacy.
The relationship between sociodemographic, family, and health literacy variables in the study group
Table 2 presents the relationship between sociodemographic, family and health variables, and health literacy levels (HLS-EU-Q16). Age, financial capabilities, family function (Family Apgar), and mental health condition (GHQ-28) were found to be significantly associated with health literacy levels in both urban and rural residents. Young respondents and study participants with stronger financial capabilities and no significant disturbances in the family system, as well as with good mental health condition, were more likely to score a sufficient level of health literacy. Additionally, among rural residents, the level of health literacy was significantly related to gender, education, source of income, financial situation, and co-morbidities. Women, people with higher education, students, or the unemployed, who consider their financial situation as good or very good and who do not have any co-morbidities, are more likely to score a sufficient level of health literacy.
The relationship between the health literacy level and sociodemographic, family, and health variables depending on the respondents’ place of residence in a multidimensional model
Table 3 reveals the relationship between the analysed sociodemographic, family, and health variables and the health literacy level depending on the place of residence of respondents in the study group. Model 1 was statistically significant (F = 5.096, p < 0.001). With regard to urban residents, the health literacy level was positively associated with family function (Family Apgar), while financial capabilities and mental health condition (GHQ-28) were negatively associated with HL. The model’s variables explained 17% of the variation in health literacy (R2 = 0.177).
Model 2 was statistically significant (F = 7.953, p < 0.001). Financial situation, source of income, and family function (Family Apgar) were variables positively associated with health literacy among rural residents, while gender and mental health condition (GHQ-28) were negatively associated with HL. The model’s variables explained 27% of the variation in health literacy (R2 = 0.272).

Discussion

In this study, we assessed the health literacy level and its selected determinants among patients using primary health care services based on their place of residence. According to the study results, inadequate or problematic health literacy levels are found in approximately 46.5% of the study sample. This indicates that almost one in two people might have difficulties with accessing, understanding, appraising, and using health-related information. Our study results are consistent with those of the European Health Literacy Survey (HLS-EU) [14] and other Polish studies [12, 15]. We discovered that the place of residence of respondents has no significant impact on their health literacy level. According to our study, 52.5% of urban residents and 47.5% of rural residents had a sufficient level of health literacy. More than half of those with inadequate level of health literacy (51.1%) lived in rural areas, while a problematic level of health literacy mainly concerned urban residents (52.5%).
These findings contradict the Aljassim and Ostini review of health literacy in rural and urban populations [20]. According to the above research, significantly higher levels of health literacy were found in urban residents [21–23]. It should be noted, however, that the aforementioned studies did not include European countries. Instead, they were mainly carried out in developing countries and the United States of America (USA). The disproportion in the health literacy levels in these countries may result from urban-rural differences in infrastructure, education, access to health care, or residents’ financial situation, which may lead to huge disparities in health outcomes. In contrast, the analysis of health disparities among European Union (EU) countries revealed that there are no significant differences between rural and urban areas in a global perspective [24]. Our study results support the hypothesis that stereotypes about lower health literacy among rural residents are fading because of better access to medical care in cities and a small number of medical facilities in rural areas, as shown by the “Polish countryside 2020” report [25]. As a result, the differences in the health literacy level between rural and urban residents can be attributed to other factors.
The respondents who took part in this study came from the Lubelskie Province of eastern Poland. Based on the data from the Statistical Office in Lublin for 2022, most of the population in this region live in rural areas. Lubelskie Province has a total urban population of 46.2%, compared to a total rural population of 59.7% [26]. According to the Central Statistical Office (GUS) data from 2021, Lubelskie Province has the highest percentage of relatively poor people (22.9%). This region is also characterised by one of the lowest annual average earnings per person and a high level of income inequality [27]. The number of professionally active population in Lubelskie Province in the fourth quarter of 2022 was 947,000, or 5.5% of all professionally active people in the country, according to data from the Labour Force Survey (LFS). Most professionally active people were men (54.5%), with rural residents accounting for 55.5% [28].
The above data may help to explain the strong correlation between the health literacy level and respondents’ financial and livelihood conditions in rural areas. According to our research results, the participants who considered their financial situation as average/poor and those who assessed their financial status negatively had the lowest health literacy levels.
Financial situation has an impact on general health condition and disease prevention. The results of the National Health Test of Poles of 2020 indicate that one in every 5 Poles has avoided seeing a doctor at least once in their lives for financial reasons, and one in every 4 has avoided visiting the dentist for the same reason, while 15% of all Poles have decided not to buy a prescription drug and 9% have refrained from purchasing medical equipment [29]. Poor financial capabilities to purchase medicines or make a doctor’s appointment were also a significant predictor of low health literacy levels among urban residents. In our study, employed urban residents had higher levels of health literacy than did students/unemployed or pension beneficiaries. Higher levels of health literacy among employed persons may be attributed to the fact that employment provides good opportunities for general literacy learning, which improves reading comprehension ability and may affect health literacy outcomes [30].
Findings concerning the level of health literacy among rural residents were more surprising. Here, sufficient levels of HL were noticeably more prevalent among unemployed persons or students. This group also had the lowest percentage of people with inadequate levels of health literacy. These findings may be explained by the fact that a greater percentage of the unemployed or students from rural areas had already encountered health-related issues during their time of education. According to our study results, education has a significant impact on the health literacy level among rural residents, which has been confirmed by other studies [31–33]. Additionally, rural residents with higher education are more likely to have a sufficient level of health literacy than are urban residents with higher education (73.8% versus 59.3%). This may be due to the strong belief among rural residents that obtaining a university degree leads to better social and living conditions through the acquisition of a well-paid job. As a result, it can be assumed that rural residents who pursue higher education are more committed to acquiring and expanding their knowledge, including health awareness.
Multivariate analysis was used to identify predictors of health literacy levels in the study group based on the respondents’ place of residence. The Family Apgar scale, which measures self-assessment of family function, is one such factor. Rural and urban residents with higher Family Apgar scores were characterised by higher levels of health literacy. This result is consistent with other authors’ findings [34–36]. A person’s capacity to obtain and understand medical information and to use the health care system can be enhanced with the help of family and loved ones. This is especially important for people with a low health literacy level, because it encourages the development of health-seeking attitudes and behaviours, increases the frequency of preventive medical visits, improves health, and lowers medical costs [37]. Additionally, there is a strong correlation between self-management of chronic disease and family support [36]. Family members support the patient’s disease management and self-monitoring behaviours, which improve health outcomes and raise health literacy levels.
Mental health condition (GHQ-28) was discovered to be a further predictor of health literacy, regardless of the respondents’ place of residence. Our research found that as people’s mental health condition deteriorated, their health literacy levels decreased. These results contradict the findings of other authors who found no correlation between mental health condition and health literacy. It should be noted, however, that in other authors’ studies [32, 38], people with low health literacy levels were more likely to report severe somatic symptoms. This leads to the conclusion that the perception of chronic disorders and physical limitations in daily activities increases the likelihood of a problematic health literacy level.
It should also be noted that gender was a significant predictor of health literacy among rural residents. Women living in rural areas had significantly higher levels of health literacy. Due to the fact that women interact with healthcare providers more frequently as compared to men because they usually take care of their family members, they tend to have higher health awareness. This is especially noticeable in rural areas, where women are more likely to stay at home and take care of the family and household. This is frequently caused by the lack of suitable childcare facilities in rural areas, such as day care centres and kindergartens. On the other hand, it might be a result of the mindset of women living in rural areas. This study was conducted in primary health care facilities. It should be noted that according to the analysis of the use of health care services in 2009 by the National Health Fund (NFZ), the number of women from reproductive age to advanced old age who used outpatient specialist services was higher than men in comparable age brackets [39].

Conclusions

According to the results of the study conducted among PHC patients in rural and urban areas, urban residents were found to have higher levels of HL, but the relationship was not statistically significant. Most respondents, regardless of their place of residence, were characterised by a sufficient level of HL. Age, financial capabilities, family function, and mental health condition were found to be significantly associated with health literacy levels in both urban and rural residents. Additionally, among rural residents, the level of health literacy was significantly related to gender, education, source of income, financial situation, and co-morbidities. In a multivariate analysis, it was found that health literacy levels among urban residents were positively associated with family function, but negatively associated with financial capability and mental health condition. Financial situation, source of income, and family function were positively associated with HL among rural residents, while gender and mental health condition were negatively associated with HL. Our study results emphasize the importance of improving health literacy levels across society. Primary health care facilities are an excellent location for introducing health programs increasing health literacy. Such health programs are currently unavailable in Poland.
