Abstract

Background
Occupational diseases that are often found in the porter (transport worker) are related with the
changes in the structure of the spine. Work load, length and duration of work are factors that affect
the spine curve. This study aims to see whether there is a relationship between those factors with
the incidence of kyphosis among the workers.

Methods
The study used an observational study with a cross-sectional design that included 51 male workers
aged 15-65 years in Sumbawa Regency. Sample selection is done in consecutive random sampling.
Workers who had conditions such as a history of spinal surgery, spinal fractures, spinal tumors,
spinal infections and osteoporosis were not included in the study. The curve of thoracic kyphosis is
measured by flexible ruler. The calculation of the degree uses a standard and predetermined
kyphosis index formula. Data on carrying loads, duration of work per day and length of work is
obtained from the results of questions and answers with workers. The Fisher test was used as a
statiscal analysis with a p value <0.05.

Results
In this study, 60.8% of the porter had worked for more than 10 years and most had a carrying load of
> 40 kg with the duration of work more than 8 hours per day. Measurements of the curvature of the
vertebrae found that 35 people (68.6%) had normal curves followed by 16 people (31.3%) had
kyphosis. Statistical test results with Fishertest found a significant relationship between carry load
(p=0.003), duration of work (p=0.047) and working period (p=0.037) with kyphosis.

Conclusions
There is a significant relationship between the load of transport and the incidence of kyphosis in
transport workers. The length of work per day and working period also have a significant influence
on the efficacy of kyphosis.
