Review Meta Analysis
The association between the weight of schoolbags and low back pain among schoolchildren. A systematic review, meta-analysis and individual patient data meta-analysis.
The objective of this study was to determine whether carrying a heavy schoolbag is associated to a higher prevalence of low back pain (LBP). ⋯ This systematic review, with a meta-analysis and an IPD meta-analysis, failed to find a link between schoolbags weighing ≥ 10% of body weight and LBP among schoolchildren aged 9 to 16. Further longitudinal studies, with large samples, long follow-up periods, and rigorous methods taking into account duration of carry and the physical capacity of each subject, are required in this field.

Multiple cohort and systematic review studies exist, reporting independent predictive factors associated with outcome in musculoskeletal populations. These studies have found evidence for a number of "generic" factors that have been shown to predict outcome across musculoskeletal patient cohorts. This review provides a higher level review of the evidence with a focus on generic patient factors associated with functional musculoskeletal outcome with a view to informing predictive modelling. ⋯ This article identifies "generic" patient factors that predict functional outcome (measured using Patient Reported Outcome Measures (PROMs)) across musculoskeletal conditions. Findings provide support for the development and content of generic musculoskeletal prognostic models including models used to case-mix adjust PROM data for baseline complexity. Generic musculoskeletal models and functional PROMs would facilitate more feasible comparison and benchmarking of musculoskeletal services in order to identify variation and address health inequalities.

Incidence of shoulder pain in 40-year-olds and over and associated factors: a systematic review.
Shoulder pain is one of the most frequent musculoskeletal complaints, and its prevalence and consequences increase with age. However, little is known about the incidence of shoulder pain among aging adults. We conducted this review to estimate the incidence of shoulder pain in ageing adults and its associated factors. ⋯ Shoulder pain is one of the most frequent musculoskeletal complaints, and its prevalence and consequences increase with age. However, since the prevalence of a recurring condition is determined by its incidence and the number and duration of episodes, it is important to have valid incidence estimates and to conduct aetiological studies on incidence measures to untangle risk factors of the occurrence of shoulder pain from those affecting the duration and number of episodes . In this systematic review, we sought to estimate the incidence of shoulder pain in ageing adults along with its associated factors. This work could lead to better interventions to prevent shoulder pain in older individuals.

The transition from adolescence to adulthood is a sensitive period in life for health outcomes, including back pain. The objective was to synthesize evidence on risk factors for new episodes of back pain in emerging adults (18-29 years). ⋯ Emerging adulthood is a transitional period of life with changes in life style, potentially influencing future musculoskeletal health. This systematic review included 49 articles evaluating more than 150 potential risk factors for back pain, one of the most prevalent musculoskeletal disorders. No consistent results were found for life style factors such as physical activity level or BMI, both highlighted as important risk factors in previous literature. Importantly, a previous episode of back pain was a consistent risk factor for a new episode of back pain across several studies, and further investigation of risk factors for the first back pain episode is needed.

Psychological interventions designed to enhance positive affect are promising ways to promote adaptive functioning in people with chronic pain. However, few studies have addressed the efficacy of positive affect interventions in chronic pain populations and examined which patients can benefit more from them. The aim of the present study was to identify mediators and moderators of the best possible self intervention (BPS) in fibromyalgia patients. ⋯ This study presents evidence about who can benefit from an intervention designed to augment positive affect and promote positive functioning in FMS patients and how these changes occur. It extends previous findings on patient characteristics associated with the response to pain management interventions.
