Introduction:
Hard work in the countryside can lead to the onset of pain conditions, which in turn trigger different degrees of labor reduction and musculoskeletal disorders. Low back pain is one of the most common disorders that lead to inactivity, and obesity seems to be associated with the development of low back pain symptoms, since abdominal fat causes mechanical demands in this region due to excessive load.
Objectives:
To analyze low back pain and its relationship with body composition, flexibility, and posture in rural workers.
Methods:
Rural workers (n = 55) were grouped according to the presence of low back pain or absence of low back pain symptoms. Body composition, flexibility, and posture were assessed and compared between groups. A principal component analysis was used to group variables to identify possible associations among variables and low back pain.
Results:
The low back pain group presented greater obesity rates than the group without symptoms. Regarding low back pain prevalence, most of the participants had pain symptoms and showed postural deviations. Principal components analysis showed that the group without symptoms was mainly related to the amount of muscle tissue, while the low back pain group was to the adipose tissue.
Conclusions:
Low back pain appears to be associated with body composition and postural deviations, while musculoskeletal and adipose tissues are protective and risk factors for low back pain, respectively, in rural workers.

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
