BACKGROUND
Chronic pain is a major health problem, considered as a disease in its own right. The prevalence of chronic pain is estimated to be between 2% and 40% in adult populations. In Niger, there are no data on chronic pain.
OBJECTIVE
This study was designed to provide the demographic, clinical and etiological profile of chronic pain in patients from Niger in order to create a database on chronic pain in Niger.
METHODS
Our study is prospectively conducted at the department of external consultation of the Hôpital National de Niamey over a period of 10 months from 31 May 2016 to 30 January 2017 collecting all cases of chronic pain. The demographic, clinical and etiological characteristics of all patients were collected and analyzed.
RESULTS
During the period of the study, 1927 patients consulted at the department of external consultation of the Hôpital National de Niamey, among which 411 patients had chronic pain (21.33% [95% CI: 19.53% and 23.13%]). The average age was 48.28 years (±12.84) with 51.6% of patients aged over 50 years. The male sex was predominant (61.8%). The most common sites of chronic pain were legs (25.5%), back (14.4%), neck (13.6%), knees (13.4%) and feet (13.1%). Osteoarthritis was the most common cause of chronic pain (35.5%), followed by herniated disc (22.2%), spondylodiscitis (14.6%) and migraine (4.1%). Significantly patients aged 50-59 years suffered from neck and legs pain (p value<0.001). Significantly chronic headaches and rheumatoid arthritis were more common in women while osteoarthritis, herniated disc and spondylodiscite were more common in men (p value=0.001). Significantly osteoarthritis and herniated disc were more common in patients older than 40 years (p value<0.001).
CONCLUSIONS
Our study provides demographic, clinical and etiological data of chronic pain in patients from Niger, and shows that chronic pain is a common reason for consultation in Niger concerning 1 in 5 patients with a high prevalence among men and patients aged over 40 years.
