include individual characteristics, namely body mass
index, height, exercise habits, years of work, work
position, and workload weight (Harrionto, 2007).
The weight of the load lifted, the frequency of
lifting, and the method or technique of lifting
weights can affect workers' health in the form of
work accidents or the emergence of pain or injury to
the back (Effendi, 2007).
Occupational Safety and Health Administration
(OSHA, 2013) explains that occupational diseases
are the result of injuries or illnesses that occur in the
workplace as a result of material pressure or
working conditions while doing work. The
prevalence of spinal complaints reaches almost 60%
of all occupational diseases in nurses. In the United
States, 85% of the population is in second place
when it comes to doctor visits because of symptoms
of musculoskeletal complaints in risky occupations.
Fortunately, complaints of back pain resolve for the
most part in 2-4 weeks (Hills, 2020).
Many workers from various countries were
reported by The ILO Report for World Day Safety
and Health at Work in 2005 about the issue that 30%
of these workers felt complaints of disease and
discomfort in the back area and experienced
musculoskeletal events. Data reported by the
National Safety Council (NSC) in the state of Israel
has a prevalence rate of back pain in nurses of
around 16.8%. In Australia, there are 87% or 813
nurses experiencing LBP. The cases in the United
States regarding the incidence of musculoskeletal
injury are 4.62 per 100 nurses per year (Kepmenkes
RI, 2010).
Based on data obtained from Health and Safety
Excutive (2014), the prevalence of LBP during the
last 12 months in 2013/2014 in Great Britain, there
were 310 cases of LBP, and an estimated prevalence
of new cases was 150 cases. According to the Center
for Control and Prevention (CDC) in the The
American Academy of Pain Medicine (2011), at
least 100 million American adults report pain
complaints. The highest cause is low back pain at
28.1%. Expensive LBP treatment depends on
geography and facilities. Lumbar MRI (Magnetic
Resonance Imaging) prices vary between $ 300 and
$ 2,500 with a national average of $ 894 (Reilly
jacob et al, 2019)
Riskesdas 2018 data shows that 6.5% of workers
have back injuries, 32.7% have injuries to the upper
limbs, and 67.9% have injuries to the lower limbs
(Kementerian kesehatan, 2018). The results of data
from the Directorate General of Medical Services of
the Republic of Indonesia (2006-2008) regarding
occupational diseases in 2005, 2006, and 2007, of
the ten occupational diseases, LBP complaints rank
first with the highest number of cases. Workers with
a work posture of carrying, pulling, and pushing
(manual handling) and lifting (lifting) are the leading
causes of LBP. About 25% of work accidents occur
due to manual material handling work, and about
74% of spinal injuries are caused by lifting activities
(Hastono, 2006).
Nutritional status is one of the causes of fatigue.
A person's nutritional status can be measured by
BMI. A workforce with good nutritional status will
have better work capacity and endurance, and vice
versa. In a state of malnutrition with a non-
ergonomic work position, it will interfere with work,
reduce productivity and body endurance so that it is
easy to catch diseases and accelerate the onset of
fatigue (Budiono, 2003). A person with excess
weight and body fat will put pressure on the spine
when holding loads so that it is easy to damage the
bone structure and a danger to the spine. This
statement is supported by Setyanigrum (2014)
research that shows there is an influence between
BMI and LBP with a p-value of 0.000.
Research conducted by Sakinah (2013) states
that the percentage of LBP in the age group less than
35 years who experience complaints is seven people
(26.9%) and those who do not experience LBP are
19 people (73.1%). The age group over 35 years
who share LBP complaints are 17 people (60.7%)
and 11 people who do not experience complaints
(39.3%). This is in line with research conducted by
Shieh et al (2017) where the complaints of LBP
increase with age. The majority of nurses in the 35
year age group experienced LBP as much as 75.5%
(37/49) and the 20-24 year age group as much as
65.2% (214/328) nurses. The results of statistical
tests from this study indicate that there is a
significant relationship between age and LBP
complaints on brick workers in the Lawawoi
Village, Sidrap Regency. As you get older, the
muscles' flexibility also decreases, making it easier
for muscle and joint stiffness to occur. In addition,
there is also a narrowing of the space between the
vertebrae, which causes the spine to become
inflexible like it was at a young age. This can cause
pain in the spine to the waist (Idyan, 2008). In fact,
80% of back pain affects people aged 20-55 years.
However, this complaint is not specific to this age
group, which means that back pain can occur due to
infection, trauma, or other specific reasons
(Movahedi et al., 2020).
The excessive workload can lead to over-
stretching of the muscles to reduce the immune
elements that are between the spinal segments.
