Mapping evidence on the prevalence, incidence, risk factors and cost associated with chronic low back pain among adults in Sub-Saharan Africa: a systematic scoping review protocol

BACKGROUND: Globally, low back pain (LBP) is a major public health problem affecting mainly adults of the working class and is the leading cause of disability. The estimated lifetime prevalence of LBP is 50 to 80%. From 1990 to 2015, the years lived with disability caused by LBP have scaled up by 54% with the greatest increase observed in low-middle-income countries (LMICs). LBP poses a significant socio-economic burden to the society regardless of all the technological advancement in diagnosis and intervention approaches in recent years. Despite an increase in the literature of LBP in LMICs, chronic low back pain (CLBP) is poorly investigated yet it is responsible for the largest amount of burden. The purpose of this scoping review is to map the existing evidence on the prevalence, incidence, mortality, risk factors, and cost associated with CLBP among adults in Sub-Saharan Africa (SSA). METHODS: We will conduct a scoping review to explore, describe, and map literature on the prevalence, incidence, mortality, risk factors, and costs associated with CLBP among adults in SSA. The search will be performed using the EBSCOhost platform by searching the following databases within the platform: Academic search complete, health source: nursing/academic edition, CINAHL with full text, Embase, PubMed, MEDLINE, Science Direct databases, Google Scholar, and the World Health Organization library databases. The search will include peer-reviewed, review articles, and gray literature. The first (title and abstract) and the second (full text) screening phases will be performed by two independent reviewers, with the third reviewer employed to adjudicate discrepancies. The reference list of all included articles will also be searched for eligible articles. This scoping review will be reported in accordance to the MOOSE and PRISMA-ScR guidelines. The NVivo 12 data analysis software will be used to generate themes, and a thematic content analysis will be used to give the narrative account of the review. DISCUSSION: The study anticipates finding relevant literature on the prevalence, incidence, risk factors, mortality, and cost associated with CLBP among adults in SSA. The study outcomes will aid in identifying research gaps, planning, informing policy, commissioning of future research, and funding prioritization.
