The relationship between chronic diseases and the intensity and duration of low back pain

BACKGROUND: Low back pain (LBP) is a worldwide problem that affects numerous people and limits their mobility. Several factors, including chronic diseases, increase the risk of developing LBP. To date, the information available about the relationship between chronic diseases and the intensity and duration of LBPis quite limited. AIM: The aim of the present study was to address the relationship between chronic diseases and both the intensity and duration of LBP. DESIGN: This is an observational cross-sectional study. SETTING: The study was conducted in the community of Saudi Arabia. POPULATION: 2181 adult participants (aged 18 years or more, mean age of 33 and standard deviation [SD] of ±11, 61% females) from Saudi Arabia with either recent or recurring LBPparticipated in the study. METHODS: The participants of this study were surveyed, and their demographic information was obtained. They were asked whether they had LBPduring the past year, and if they had, they were asked about their LBPin terms of the pain intensity on a scale that runs from 0 to 10, where 0 indicates no pain and 10 indicates extreme pain. Further, the participants were asked how long their pain lasted (in days). They were also inquired whether they had any of the following chronic diseases: diabetes mellitus, high blood pressure, hypotension, arthritis, cardiopulmonary diseases, kidney diseases, and hypothyroidism. Logistic regression was used to analyze the relationships between both of LBP's intensity and duration, and the presence of chronic diseases, while adjusting for the potential effect of age and gender. RESULTS: Atotal of 2181 adults with either new onset of or recurrent LBPduring the past 12 months participated in the present study. Of these, 356 (16%), who had LBP, suffered from one or more of the said chronic diseases. It was found that having one or more chronic diseases had statistically significant relationship with increased LBP's intensity (P=0.002), as well as prolonged duration (P=0.001). In particular, hypertension, arthritis, and hypothyroidism have statistically significant relationship with increased the intensity of the pain (P<0.05). Only, hypertension and arthritis have statistically significant relationship with increased the duration of pain (_Astate≤0.001). CONCLUSIONS: The presence of chronic diseases was associated with a more intense and longer duration of LBP. CLINICALREHABILITATION IMPACT: In view of the results of this study, we expect that those who have chronic diseases will have a longer duration of LBPand more intense pain.
