RESUMO
This study aimed to evaluate the impact of low back pain on the perceived health-related quality of life of children between 6 and 12 years of age. This is a cross-sectional study of three hundred seventy-seven students from three schools (two private and one public) located in the city of Botucatu, São Paulo. Data were collected using the Pediatric Quality of Life Inventory (PedsQL, version 4.0), a questionnaire comprising questions on personal background, sociodemographic and socioeconomic information, and a questionnaire about quality of life. Comparisons were made between groups with and without low back pain. The chi-squared test was used for analyzing categorical variables, and the non-parametric Mann-Whitney test was used for continuous variables. According to the findings obtained in this study, it was observed that low back pain in the last month was reported by 27.3% of the total participants. The perceived health-related quality of life was lower among individuals who had low back pain, and the scores of physical and emotional functioning domains were also lower in the presence of low back pain. The prevalence of low back pain among children and adolescents is relatively high. Furthermore, the repercussions of low back pain may lead to a lower overall perception of the health-related quality of life in this population and affect aspects of physical and emotional functioning.
RESUMO
BACKGROUND: Low back pain (LBP) is highly prevalent in children and adolescents, while psychosocial, anthropometric, developmental, and lifestyle factors have been associated. However, the evidence is inconsistent from a biological point of view, so identifying predictors of LBP in the 6-12 years children through physical examination should be appropriate. AIMS: To estimate the prevalence of LBP and associated factors in schoolchildren in a Brazilian population. DESIGN: Cross-sectional study. SETTING: Three schools in Botucatu, Brazil. PARTICIPANTS/SUBJECTS: 377 students from 6-12 years. METHODS: Data collection consisted of questions regarding personal history, socioeconomic and anthropometric information, kinesiologic evaluation with anthropometry, lumbar biophotogrammetry, and backpack weight and use. Descriptive analyses were performed, and simple and multiple logistic regression models were used for risk factors. RESULTS: The prevalence of LBP was 27.32% (confidence interval [CI] 95% = 23.07-32.03). The mean age was 8.85 years (± 1.83) in the group with LBP and 8 years (± 1.76) in the group without LBP (p = .006). Variables such as backpack weight (odds ratio [OR] = 1.45, CI 95% = 1.018-2.064) and exceeding 3 hours per day in front of the television (OR = 7.97, CI 95% = 1.957-32.515) increased the chance of LBP in these students. CONCLUSION: LBP is prevalent in younger schoolchildren, and the factors associated with this outcome can be effectively addressed through the promotion of health measures. LBP in schoolchildren is a musculoskeletal discomfort that negatively affects the quality of life of these individuals and persists in adulthood.

PURPOSE: To estimate the prevalence of indicative signs and symptoms of carpal tunnel syndrome (CTS) during the third trimester of pregnancy; assess the severity of symptoms and functional impairment; evaluate associated factors; and to evaluate the complaint of CTS in pregnant women through ultrasonography (USG). METHODS: A cross-sectional study, in which participants were classified into two groups: presence and absence of indicative signs and symptoms of CTS. Severity of symptoms and functional status was assessed by the Boston Carpal Tunnel Questionnaire. USG was performed by multiplanar technique of static and dynamic evaluation. Association between USG and indicative signs and symptoms of CTS was estimated using Fischer's exact test and Poisson regression models were used to estimate the association of exploratory variables and indicative signs and symptoms of CTS. RESULTS: Altogether, 482 women were recruited and 111 presented indicative signs and symptoms of CTS, resulting in a prevalence of 23.03%. USG was not able to distinguish indicative signs and symptoms of CTS groups. Both the severity of the symptoms and the impairment of the manual function were mild. Being left-handed, gestational diabetes mellitus and maternal age were associated with indicative signs and symptoms of CTS. CONCLUSIONS: The high prevalence of indicative signs and symptoms of CTS and the difficulties that they can cause reinforce the importance of adequate diagnosis and treatment. Further studies are needed to assess the value of USG as a diagnostic method for CTS during pregnancy.
