How do musculoskeletal disorders impact on quality of life in Tanzania? Results from a community-based survey.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThere are little available data on the prevalence, economic and quality of life impacts of musculoskeletal disorders in sub-Saharan Africa. This lack of evidence is wholly disproportionate to the significant disability burden of musculoskeletal disorders as reported in high-income countries. Our research aimed to undertake an adequately powered study to identify, measure and value the health impact of musculoskeletal conditions in the Kilimanjaro region, Tanzania.
designA community-based cross-sectional survey was undertaken between January 2021 and September 2021. A two-stage cluster sampling with replacement and probability proportional to size was used to select a representative sample of the population.
settingThe survey was conducted in 15 villages in the Hai District, Kilimanjaro region, Tanzania.
participantsEconomic and health-related quality of life (HRQOL) questionnaires were administered to a sample of residents (aged over 5 years old) in selected households (N=1050). There were a total of 594 respondents, of whom 153 had a confirmed musculoskeletal disorder and 441 matched controls. Almost three-quarters of those identified as having a musculoskeletal disorder were female and had an average age of 66 years. PRIMARY AND SECONDARY OUTCOME MEASURES: Questions on healthcare resource use, expenditure and quality of life were administered to all participants, with additional more detailed economic and quality of life questions administered to those who screened positive, indicating probable arthritis.
resultsThere is a statistically significant reduction in HRQOL, on average 25% from a utility score of 0.862 (0.837, 0.886) to 0.636 (0.580, 0.692) for those identified as having a musculoskeletal disorder compared with those without. The attributes 'pain' and 'discomfort' were the major contributors to this reduction in HRQOL.
conclusionsThis research has revealed a significant impact of musculoskeletal conditions on HRQOL in the Hai district in Tanzania. The evidence will be used to guide clinical health practices, interventions design, service provisions and health promotion and awareness activities at institutional, regional and national levels.
