DESIGN: A cross-sectional study.
METHODS: Data from the International Spinal Cord Injury Community Survey (InSCI) were analyzed. The PI problems were assessed using the Spinal Cord Injury Secondary Condition Scales (dichotomized to "having problem" and "not having problem". Health service systems were categorized as an inpatient-oriented SCI specialized system and a primary care-oriented system. A directed acyclic graph was applied to create a multivariable logistic regression model to determine the independent influencing factors of PI problems.
RESULTS: Of 790 included participants, 277 (35%) had PI problems. Being recruited from countries with inpatient-oriented SCI specialized systems (Model 1) and visiting rehabilitation medicine/SCI physicians at least once a year (Model 2) is an independent negative correlating factor of PI problems (odds ratio = 0.569 [95%CI: 0.374-0.866] and 0.591 [95%CI: 0.405-0.864], respectively).
CONCLUSION: SCI-specialized health service systems might be a protective factor of PI problems in middle-income country contexts. This result suggests the importance of having SCI-specialized services in middle-income countries to reduce the prevalence of PI problems.
METHOD: This cross-sectional multicentre study investigated a healthy paediatric population aged 4-18 years in Indonesia. The 6-minute walk test (6MWT) was conducted in accordance with the American Thoracic Society guidelines. Data were presented as the 6MWD according to age and sex per year. Univariate and multivariate analyses were conducted on the basis of the 6MWDpred Rizky formula.
RESULTS: A total of 634 participants were included in this study. Age, sex, weight, leg length and height affected the 6MWD (P<0.001). In the regression model, sex and height were the predictors of 6MWD, with height as the best single predictor.
CONCLUSION: The reference charts and 6MWDpred Rizky formula are applicable in multi-ethnic paediatric Indonesian populations but in limited settings.
