Obesity and osteoarthritis in knee, hip and/or hand: An epidemiological study in the general population with 10 years follow-up
<p>Abstract</p> <p>Background</p> <p>Obesity is one of the most important risk factors for osteoarthritis (OA) in knee(s). However, the relationship between obesity and OA in hand(s) and hip(s) remains controversial and needs further investigation. The purpose of this study was to investigate the impact of obesity on incident osteoarthritis (OA) in hip, knee, and hand in a general population followed in 10 years.</p> <p>Methods</p> <p>A total of 1854 people aged 24–76 years in 1994 participated in a Norwegian study on musculoskeletal pain in both 1994 and 2004. Participants with OA or rheumatoid arthritis in 1994 and those above 74 years in 1994 were excluded, leaving n = 1675 for the analyses. The main outcome measure was OA diagnosis at follow-up based on self-report. Obesity was defined by a body mass index (BMI) of 30 and above.</p> <p>Results</p> <p>At 10-years follow-up the incidence rates were 5.8% (CI 4.3–7.3) for hip OA, 7.3% (CI 5.7–9.0) for knee OA, and 5.6% (CI 4.2–7.1) for hand OA. When adjusting for age, gender, work status and leisure time activities, a high BMI (> 30) was significantly associated with knee OA (OR 2.81; 95%CI 1.32–5.96), and a dose-response relationship was found for this association. Obesity was also significantly associated with hand OA (OR 2.59; 1.08–6.19), but not with hip OA (OR 1.11; 0.41–2.97). There was no statistically significant interaction effect between BMI and gender, age or any of the other confounding variables.</p> <p>Conclusion</p> <p>A high BMI was significantly associated with knee OA and hand OA, but not with hip OA.</p
A definition of flare in low back pain (LBP): A multiphase process involving perspectives of individuals with LBP and expert consensus
Low back pain (LBP) varies over time. Consumers, clinicians and researchers use various terms to describe fluctuations of LBP symptoms. Although "flare" is commonly used to describe symptom fluctuation, there is no consensus on how it is defined. This study aimed to obtain consensus for a LBP flare definition using a mixed-method approach. Step 1 involved derivation of a preliminary candidate flare definition based on thematic analysis of consumers' views in consultation with an expert consumer writer. In Step 2, a workshop was conducted to incorporate perspectives of LBP experts into the preliminary flare definition, which resulted in two alternative LBP flare definitions. Step 3 refined the definition using a two-round Delphi consensus process with experts in musculoskeletal conditions. The definition favoured by experts was further tested with individuals with LBP in Step 4, using the definition in three scenarios. This multiphase study produced a LBP flare definition that distinguishes it from other LBP fluctuations, represents views of consumers, involves expert consensus, and is understandable by consumers in clinical and research contexts: "A flare-up is a worsening of your condition that lasts from hours to weeks that is difficult to tolerate and generally impacts your usual activities and/or emotions". Perspective: A multiphase processes produced a low back pain (LBP) flare definition that distinguishes it from other LBP fluctuations, involves expert consensus and represents consumers' views
Prevalence and pattern of co-occurring musculoskeletal pain and its association with back-related disability among people with persistent low back pain: protocol for a systematic review and meta-analysis
Background
Individuals with persistent low back pain commonly have a broad range of other health concerns including co-occurring musculoskeletal pain, which significantly affect their quality of life, symptom severity, and treatment outcomes. The purpose of this review is to get a better understanding of prevalence and patterns of co-occurring musculoskeletal pain complaints in those with persistent low back pain and its potential association with age, sex, and back-related disability as it might affect prognosis and management.
Methods
This systematic review protocol has been designed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. We will perform a comprehensive search, with no date limit, in the following bibliographic databases: MEDLINE and Embase (via Ovid), CINAHL, and Scopus for citation tracking, based on the following domains: back pain, co-occurring musculoskeletal pain, combined with a focus group that emphasizes study design. Appropriate papers will be screened against the eligibility criteria by three reviewers independently, data extracted by two independent author pairs and disagreement resolved by consensus meetings or other reviewers if required. Assessment of methodological quality and risk of bias will be conducted using a modified version of the Risk of Bias Tool for Prevalence Studies developed by Hoy and colleagues. The overall risk of bias will be determined for each included study based on the raters’ consensus of the responses to the items in this tool. In case of sufficiently homogenous studies, meta-analysis will be performed.
Discussion
Given the lack of standard terms used to define co-occurring musculoskeletal pain, the search strategy will include the broader term “back pain,” different terms for the “other co-occurring pain,” and specific study designs combined with several exclusion terms. The results of this proposed review will identify the prevalence and patterns of co-occurring musculoskeletal pain among those with persistent low back pain, which is likely to inform clinical management, research, and policy in management of musculoskeletal disorders.
