with health literacy among employees working

in the various lines of business

Nergiz Sevinc* and Burcu Korkut**

BACKGROUND
Health literacy is vital for people’s ability to manage health. It has been
known for a long time that the importance of education in increasing health
literacy is an undeniable fact. The first aim of this study was to investigate
the health literacy levels of employees working in different business lines
receiving service from the occupational health and safety unit. The second
aim was to reveal how health literacy levels are affected according to the
training duration.

METHODS
A cross-sectional study was conducted on 202 employees receiving service
from the Karabuk occupational health and safety unit. The employees
were divided into three groups as workers, officers and others. All employees
were given the questionnaire consisting of 31 questions including
sociodemographic characteristics and the adult health literacy scale. A
face-to-face interview was performed with each of the employees. Kruskal-
Wallis H and Mann-Whitney U tests were used to analyze the data.

RESULTS
The range of adult health literacy scale scores of the employees was 4-23.
There was no significant difference in adult health literacy scale scores
between age groups (p=0.38). The percentage of employees who received
more than 16 hours training course was 19.3%, 20.6%, and 46.7% for workers,
civil servants and other employees, respectively. Adult health literacy scale
scores increased in proportion to the amount of training the employees
received (p=0.001).

CONCLUSION
This study reveals that occupational health training has a positive effect
on health literacy.

INTRODUCTION

Even though health literacy (HL) is defined
in various forms by many researchers, the World
Health Organization (WHO) has defined it as
cognitive and social skills which determine the
motivation and “ability of individuals to gain
access to, understand, and use information in
wa ys  wh ic h p romote and main ta in go od
health.”(1) Developed countries started to work
hard to improve HL when it was determined
that low HL was associated with increased
hospitalization, decreased vaccination uptake,
and low participation in cancer-screening
activities in the following years.(2,3) They realized
that an individuals’ skills are an important part
of improving HL and they increased it by using
plain language in both verbal and written
communication.(4,5)

Since HL provides a significant contribution
to the health quality of all segments of society,
developed and developing countries have
prepared health and safety programs to provide
occupational health services and increase HL.
The content of these programs, which are
generally offered by the occupational health and
safety (OHS) units and prepared within the
framework of laws, vary according to countries.
There are a few studies evaluating the HL status
of different occupational gr oups such as
farmers, students and employees. For example,
a study involving 282 workers at a factory who
received the OHS training routinely showed that
13.5% had inadequate, 47.5% problematic,
30.9% sufficient, and 8.2% excellent HL
scores.(6) There was also a study conducted on
421 farmers working in Thailand, which reported
that the farmers’ mean HL level was found to
be 34.98 (SD=6.87) points over a range of 0-50
points.(7) Recently, 686 university students were
evaluated for HL status by Gamsýzkan et al.,
who found that 21.1% (n=145) of the students
had inadequate HL, 41.8% (n = 287) had limited
HL, 30.9% (n=212) sufficient, and 6.1% (n=42)
excellent HL.(8) None of these studies were
c o nd u c t e d s imu l t ane o u sl y i n  va r i o us

occupational groups by including a large labor
force in the community. The first studies on the
state of HL in Turkey was initiated by improving
the Adult Health Literacy Scale (AHLS) in
2012.(9)

The difference of this study with the
previous studies lies in the fact that the subjects
were from various occupational groups including
civil servants and employees. In the present
study, the first objective was to investigate and
compare the HL status of civil servants and
employees receiving healthcare services from
the OHS unit. The second objective was to reveal
how HL levels are affected according to the
training duration received from the OHS unit.

METHODS

Design of the study
This cross-sectional study was conducted

among employees working in different business
lines receiving service from the Karabuk OHS
unit from April to May in 2020.

Study subjects
A total of 213 workers who received the

OHS training routinely, were invited to participate
in this study. Participants enrolled in the study
were selected based on the following criteria; (a)
aged 18 to 60 years; (b) received training from
OHS unit; c) had no significant, untreated chronic
disease. Those who did not consent or had chronic
disease were  excluded. After receiving
information about the study, 11 refused to take
part. A total of 202 workers were analysed.

The profession groups involved in the study
consisted of the groups of workers (hairdressers,
barbers, auto industry workers, cleaning staff),
civil servants (railway workers, family health
center employees) and ‘others’ (dentists, x-ray
technicians, medical secretaries). According to
the training duration received from the OHS unit,
participants were divided into three subgroups.
The first subgroup consisted of 58 participants
receiving 8 hours of training or less. The second
subgroup consisted of 96 participants receiving



173

between 9-16 hours of training. The third
subgroup consisted of 48 participants receiving
more than 16 hours of training.

Instruments and measurements
Da ta  we r e  c ol l e c t e d  th r o u gh  a

questionnaire containing 12 questions aimed at
evaluating the socio-demographic characteristics
of the employees (such as age, gender, marital
status, level of education, occupation, and
economic status) and the AHLS. Thirty-one
institutions and organizations receiving service
f r om K a r a b uk OHS u n it  w e r e  vi si t e d .
Occupational health and safety training provided
by the workplace doctor and occupational health
specialist was mainly aimed at establishing safe
working and correct health behaviors in order
to prevent occupational accidents and diseases.
The training topics provided by OHS unit are
shown in Table 1. Individuals were informed
about t he study, and  verbal cons ent was
obtained. The questionnaire and scale were then
applied to individuals who agreed to participate
in the study.

Adult health literacy scale
The Adult Health Literacy Scale (AHLS)

was developed in 2012 by Sezer (9) who tested
its validity and reliability. The Adult Health
Literacy Scale includes health information to
determine the competence of adult individuals
in health literacy and drug use and one image
showing the organs in the body. Thirteen of the

items in the scale are yes/no questions, 4 are
fill-in-the blank, 4 are multiple choice, and 2 are
matching questions. Each question type is scored
separately. In the Yes/No questions, 1 point is
given to those who select positive expressions
and 0 points is given to those who select negative
expressions. In multiple choice questions, 1 point
is given to those who mark two or more correct
answers, and 0 points to those who do not know
at all or who mark the wrong answer together
with the true. In matching-type questions, 1 point
is given to more than two correct matches and
0 points were given to others.

Scores that can be obtained from the scale
vary between 0 and 23 and the total Cronbach
Alpha value of the scale was determined to be
0.77. The scale has no cut-off point. Higher
scores indicate a higher level of HL.(9)

Statistical analysis
The data were digitally evaluated by SPSS

software. Descriptive statistics were presented
as frequency, standard deviation and percentage
distribution. The Kolmogorov-Smirnov test was
used to analyze the suitability of quantitative data
for normal distribution. The scores of AHLS had
abnormal data distribution. Kruskal-Wallis H and
Mann-Whitney U tests were used to compare
the AHLS scores of the groups formed according
to sociodemographic characteristics. A p<0.05
was considered statistically significant in all
analyses.

Ethical approval was obtained from the

Faculty of Medicine of Karabuk University (2020/
217) and administrative permission was obtained
from the Provincial Health Directorate.

RESULTS

Of the 202 employees participating in the
study, 25.2% were female, 74.8% were male,
while the age range was 18 -51 years. In addition,
16.8% of the employees were at least university
graduates, 54.5% were married, and 88.6% had

social secur ity. There was no significant
difference between male and female participants
in terms of marital status, number of children,
economic income, and educational status
(p>0.05). The characteristics of the employees
are shown in the Table 2.

The range of AHL S sc ores of the
employees was 4-23. While there was no
difference in AHLS score between age groups
(p=0.03). AHLS score s increased with
educational status of the employees (p=0.001).
Although those with social security and good
economic status obtained higher scores from the
scale, there was no significant difference in terms
of disease history and number of children. The
scores of employees according to some variables
are shown in Table 3.

Although the AHLS scores were higher in
the ‘others’ occupational group (dentist, x-ray
technician, medical secretary), the difference was
not significant (p>0.05). The percentages of
employees who received 2 or more training
sessions from the OHS unit were 19.3%, 20.6%,
and 46.7% for workers, civil servants and other
employees, respectively (p=0.001) Training
duration significantly increased HL levels
(p<00.01) (Table 3).

DISCUSSION

In the present study carried out in various
occupational groups, it was shown that the mean
AHLS score was 16 (49.0%) out of 23 points,
indicating that the employees had moderate HL.
In addition, we found that as the number of
periodic health training received by the employees
from the OHS unit increased, the score obtained
from scale also increased. Although there are
many studies in the literature on HL there is no
study evaluating HL in different occupational
groups receiving OHS training. In a study
conducted by Joveini et al.(10) , it was found that
39.4% of individuals between the ages of 18-65
years had adequate health literacy. Similarly,
Güner et al. (6) conducted a study in Turkey on
282 factory workers, and reported that 39.1%

had adequate health literacy. In a recent study,
Svendsen et al.(11) reported in Denmark that 60.9%
of adults over the age of 25 had adequate HL.
The different results obtained in the present study
and other studies may be due to differences of
the groups studied, economic income level, and
educational status.

Health literacy is expected to decrease with
increasing age, due to reasons such as decrease
in using health se rvices and mutual
communication, difficulty in accessing health
inf ormation, decr ease d internet use, and

dependence on family members.(12,13) In contrast,
HL increased with age in the present study and
in the study of Nakayama.(14) On the other hand,
Jovic et al.(15) investigated 120 people in Serbia
and found that HL sc ores were lower in
individuals over 44 years of age. This difference
may be due to the following: the mean age of the
sample in the present study was 31 years, there
were no elderly employees, the sample consisted
of working individuals, and the amount of training
received from the OHS unit increased with age.

Higher level of  e duc ation and good
economic income affect HL positively in terms

Sevinc, Korkut                                                                                                             Occupational health and safety training

of accessing correct information on health, using
health services, follow-up, and communication.(16)

In the present study, AHLS scores were higher
among university graduates and employees who
declared that their economic status was good
(17.50 and 18.00, respectively). In a study
involving 8 European countries, it was found that
low education and economic status negatively
affected HL.(17) Vamos et al.(18) and Nutbeam (19)

have suggested that receiving any form of health
education or training has a positive effect on HL.
Bayati et al.(20) conducted a study on 256 health
representatives in Iran, and found a significant
relationship between the health literacy scores
before and after health education.

As mentioned above, in the present study
conducted on individuals working in various
professions the HL score was found to be higher
in participants who received more than 16 hours
of OHS training. Furthermore, a strong positive
correlation was observed between training
durations and HL levels. Due to lack of related
literature, we could not compare the results of
the study with any research. Given that health
and safety training has a significant impact on
HL, it can be said that this training encourages
employees to access health-related resources
and follow current health developments, thereby
increasing HL.

It is well known that HL is important for
every individual of the society and covers the
acquisition of health knowledge, its appraisal,
and associated decision-making.(17) The results
of the present study revealed that providing
health literacy training to employees in the
various business lines increases their HL levels.
Hence, as training plays a critical role in raising
and promoting HL levels of employees, it is
necessary to develop and expand a training
program for employees regardless of their
literacy or education levels. We think that by
achieving this goal, it is possible to create a
national action plan with the contributions of
public institutions and organizations.

The main limitation of this study is that there
are numerous different scales on HL and that

there is no standard evaluation. Secondly, since
the present study was conducted only on
employees receiving services from the OHS unit,
the health literacy scores obtained cannot be
generalized to the whole society. In addition to
health training, conducting regular examinations
for employees receiving services from the OHS
unit is important. In this regard, employers should
be informed about this issue first and encouraged
to receive services from OHS units for their
employees.

CONCLUSION

The HL level of the employees enrolling in
this study was found to be moderate, and was
related to occupational health and safety training.
