Background
The World Health Organization defines health literacy as the capacity to access information for the purpose of protecting and maintaining one’s health and the skills needed to understand, interpret and use the information gathered [
1]. Health literacy in public health is one of society’s important indicators of the degree to which the individuals can benefit from health services, become aware of their right to health and public health services, understand health education materials, take medications carefully and accurately, and benefit from other aspects of healthcare [
2]. It is ever more important today to ensure that individuals take responsibility for their own health, understand and interpret the information given to them, and make the right decisions about their health [
3]. When health literacy is deficient in a society, the general level of health of the community suffers and problems arise in accessing and using health services, caring for and managing chronic conditions, maintaining the capacity or the will to practice self-care, among other issues [
4].
Health literacy can have a positive or negative impact on parents in the context of their knowledge, attitudes and behavior with regard to accessing and benefiting from health services [
5]. It is reported that parental health literacy levels have an impact on children’s growth and development and that the children of parents with inadequate health literacy are negatively affected. Inadequate health literacy has been shown to adversely affect a child in terms of eating habits, obesity, the correct administration of medications, application to emergency facilities and asthma management, oral and dental health, consumption of fruits and vegetables, physical activity and hygienic behavior [
6‐
12]. Functional health literacy is said to be an important indicator of a child’s health and it is reported that breastfeeding self-efficacy levels rise with an increase in maternal health literacy levels [
13,
14]. It is asserted that a mother’s level of education and the functional health literacy of parents are factors that impact children’s height, as well as their growth and development [
15]. Conversely, inadequate health literacy has been associated with problems such as dwarfism, shortness and low weight [
16].
It has been reported that among those in Turkey who prefer to seek medical services first at family health centers, 30.9% have an inadequate level of health literacy (HL), 38.0% have a problematic level of HL, 23.4% have an adequate level of HL, and 7.7% have an excellent level of HL [
17]. In a study carried out in Turkey, it was found that the health literacy of parents who regularly carry out their own follow-up and follow-up of their children is higher than that of parents who have their children follow up when called by health care institutions [
18]. In one study, the level of health literacy of parents had no association with their attitudes and behavior towards childhood vaccines [
19]. Another study found that having a health problem for parents and their children increased their health literacy and that there was a relationship between parental health literacy and child health. To clarify this relationship, it is recommended to investigate the effect of parental health literacy on children’s health behavior [
20]. It is stated that parental health literacy and body weight of adolescents are not related in Turkey [
21], but no study was found that revealed the relationship between parental health literacy and anthropometric measurements of children under 6 years of age. International studies have shown that parents with a low level of health literacy are less likely to meet the needs of their children in terms of prevention and health care [
7‐
9]. There is also evidence of an association between certain health behaviors in children that have a negative impact on their health, such as low parental health literacy, socioeconomic status, less healthy diet and less physical activity [
11,
14‐
16].
Health care workers play an important role in helping communities’ access, understand and make use of health information. Public health and pediatric nurses should plan initiatives that will identify parental health literacy levels, which is a significant determinant of children’s health; they should seek to explore impacting factors, improve HL levels and ensure that parents gain the needed knowledge and develop the skills and attitudes conducive to maintaining pediatric health. In particular, nurses should guide parents and children to appropriate websites where they can find relevant health information, making sure that these resources provide accurate, reliable and updated information [
22]. On the other hand, although there are many studies on parental health literacy and children’s health behaviors, there are few that inquire into the effect of parental health literacy on a child’s health behavior or the relationship between health literacy and children’s health [
23]. We believe that this study will contribute to the literature by setting forth the relationship between levels of parental health literacy and children’s anthropometric measurements in Turkey.
The aim of this study was to identify the relationship between parental health literacy levels and anthropometric measurements of children in Turkey.

Discussion
This study, which examined the relationship between parental health literacy and children’s anthropometric measurements, found that one third of parents had adequate health literacy and that these levels could be associated with education, income level and employment status. In addition, an association was found between the adequate level of health literacy of the parents and the Standard Deviation Scores (SDS) for weight and height of their children according to age. Several studies indicate that low levels of health literacy have an impact on parents’ knowledge, attitudes and behaviors, and also on children’s health outcomes such as disease prevention, acute care and chronic disease management. In addition, low health literacy has been shown to lead to negative outcomes such as poor nutrition knowledge and behavior, higher rates of obesity, more medication errors, and more visits to the emergency department [
30,
31]. This study is the first in Turkey to show the effect of parental health literacy on children’s anthropometric measurements. It is also one of the few studies in the international literature. When reviewing the literature, it can be seen that parental literacy is mostly studied in areas such as children’s acute and chronic health problems, oral and dental health, mental health, emergency visits and caring for medically difficult children [
6,
7,
10‐
12,
14,
23]. In this study, it is assumed that only 1/3 of parents have sufficient health literacy. This situation will have a negative impact not only on children’s anthropometric measurements, but also on acute and chronic health problems, mental health and positive health behaviors.
The research found that about two-thirds of parents had inadequate or problematic health literacy, whereas about one-third had adequate or exceptional health literacy. The level of adequate health literacy found in this study is similar to that found in some of the literature reviews [
4,
32], but higher than that reported in other studies [
33‐
35]. The prevalence of adequate health literacy in our study reflects the more favorable circumstances that exist in the study area compared to other regions of the country. The prevalence of adequate health literacy in our study reflects the more favorable circumstances that exist in the study area compared to other regions of the country. This is due to the higher level of education and income of the parents, as well as their level of health knowledge and use of preventive health services. The prevalence of adequate health literacy in our study reflects the more favorable circumstances present in the study area, in comparison to other regions in the country. Our study’s reported prevalence is higher than that of previous relevant research conducted in Turkey. However, it should be noted that the rate is comparatively lower than that reported in European countries. A study conducted in Europe found that only 52.7% of individuals had adequate and excellent health literacy [
36]. This finding was supported by other studies that reported the rate of adequate and excellent health literacy in the population at 60-65% [
37,
38]. These inadequate and problematic levels of health literacy highlighted in this study could potentially be attributed to factors such as economic instability, educational deficiencies, limited knowledge about health and other related gaps that exist in Turkey.
In this study, it was found that having parents with adequate health literacy was positively associated with their level of education, their level of income, their employment, their smaller family size and their self-assessment of their health. Some studies in the literature [
39] report a significant correlation between health literacy and certain demographic factors, including age and level of education, with higher levels of health literacy found among women than men, those aged 65–74, married individuals, those with a high school education or higher, and those in employment [
40]. Many studies in the Turkish literature [
4,
33‐
35,
41] and international articles [
37,
38] show consistency in the results regarding the level of health literacy among adults. The level of health literacy in a society is significantly influenced by factors related to employment, income and education [
42‐
44]. Poor socio-economic conditions are recognized as contributing to low health literacy, and health literacy serves as a mediator in the relationship between the use of preventive health services and overall health status, quality of life and health behaviors [
45]. The results of the study show that health literacy is significantly influenced by various socio-economic factors such as education, income and employment, as well as an individual’s ability to self-assess their health status.
We noted a correlation between possessing sufficient health literacy and parents’ ability to accurately evaluate their child’s health. Studies in the literature indicate that parents with high or functional health literacy exhibit preventative measures towards their children’s health [
10,
46], possess greater understanding and expertise in managing their child’s asthma [
47], instill their children with enhanced self-esteem [
48], and adopt more constructive approaches towards their children’s health [
13]. It is noteworthy for pediatric health that parents with sufficient health literacy were capable of reporting their child’s health as excellent or very good. Hence, a child’s well-being is influenced by the extent of their parents’ health literacy.
This study found no significant association between parental health literacy and a child’s body mass index. However, there is evidence to suggest that adequate parental health literacy may be associated with a child’s reduced likelihood of being unhealthily overweight and increased likelihood of being tall for their age. An important finding of this study is that rates of obesity and stunted growth were significantly lower in children of parents with adequate health literacy compared with those of parents with inadequate health literacy. A study has shown that low parental health literacy is linked to factors such as the socioeconomic status of the community, unhealthy dietary habits in children, and insufficient physical activity. These factors negatively affect a child’s health [
9]. One study found an association between low parental health literacy and low parental self-efficacy in parents of new-born babies, which negatively affected their child’s health [
49]. Another study found that parents with low health literacy put their children at increased risk of developing obesity, and that adequate parental health literacy had a positive effect on children, as they were more likely to adopt effective weight loss strategies and positive health behaviors [
50]. There is evidence of a positive association between functional health literacy of parents and adult height of children, and adequate health literacy of parents has a positive impact on child development [
15]. Some studies have shown a positive and statistically significant association between maternal nutritional literacy and children’s weight for age, height for age and body mass index [
49,
51], and maternal nutritional literacy has been found to be effective in preventing stunting [
52].
In this study, it is clear that there is a sufficiently positive relationship between having parents with adequate health literacy and assessing their children’s health, not being overweight for their age and being tall. It can be said that this situation may indicate that adequate parental health literacy may be effective in influencing positive health-related behaviors in children. Based on this situation, it can be said that adequate parental health literacy will positively influence anthropometric measurements of children aged 0–6.
Strengths and limitations
This study is one of the few studies that has been conducted to determine the relationship between parental health literacy and children’s health. In this research explored the factors associated with parental health literacy as well as the relationship between parental health literacy and children’s health. It is important in terms of improving children’s health that health providers make an evaluation of the level of parents’ health knowledge and health literacy when they bring their children in for healthcare at primary care facilities.
The first and most important limitation to our study was that it was carried out in only one family health center. The second limitation is that all data on the data collection form other than the children’s measurements were based on self-reporting. Meanwhile, the fact that the study sample represented 70% of the study population and had a power of 96% were the strong points in the research.
Conclusions
We found that the adequate health literacy of the parents we studied was higher than average for Turkey, but remarkably lower than the European average. In this study, it was found that parents’ adequate level of health literacy had a positive association with their level of education, employment status and income level. It also found that parents’ adequate health literacy was positively associated with their children’s health rating, weight for age and height for age, but not with the child’s body mass index for age. As a result, adequate parental health literacy has an impact on children’s anthropometric measurements. In light of these findings, we recommend that health care institutions and health professionals assess parents’ health knowledge and health literacy when they apply to health care institutions, and also implement practices that help to improve health literacy. In this context, educational programs to improve parents’ health literacy can be planned by health care institutions. Health care providers can reduce the impact of inadequate health literacy by trying to match families’ health care needs with their health literacy. It may also be beneficial to carry out more studies on the effects of parental health literacy on the health of children, and also on ways to increase the level of health literacy in general.
