RESUMO
OBJECTIVES: To describe the degree of disability, anthropometric variables, quality of life (QoL), and school backpack weight in boys and girls aged 11-17 years. The differences in QoL between those who did or did not report low back pain (LBP) were also analyzed. METHODS: Eighty-six girls (13.9 ± 1.9 years of age) and 63 boys (13.7 ± 1.7 years of age) participated. LBP was assessed by questionnaire, and disability using the Roland-Morris Disability Questionnaire. QoL was assessed by the Pediatric Quality of Life Inventory (PedsQL). Multivariate analyses of variance and covariance were used to assess differences between groups. RESULTS: Girls reported higher disability than boys (p = 0.01), and lower QoL in the domains of physical (p < 0.001) and emotional functioning (p < 0.01), psychosocial health (p = 0.02) and physical health summary score (p < 0.001), and on the total PedsQL score (p < 0.01). School backpack weight was similar in both genders (p = 0.61) and in participants with and without LBP (p = 0.15). After adjustments, participants with LBP reported lower physical functioning (p < 0.01), influencing lower physical health summary score (p < 0.01). CONCLUSIONS: Girls had higher disability and lower QoL than boys in the domains of physical and emotional functioning, psychosocial health, and physical health summary scores, and on the total PedsQL score; however, similar school backpack weight was reported. Participants with LBP revealed lower physical functioning and physical health summary score, yet had similar school backpack weight to those without LBP. .
OBJETIVOS: Descrever o grau de incapacidade, as variáveis antropométricas, a qualidade de vida (QV) e o peso das mochilas escolares em meninos e meninas com 11-17 anos. Também são analisadas as diferenças na QV entre os que relataram ou não lombalgia (LBP). MÉTODOS: 86 meninas (13,9 ± 1,9 anos) e 63 meninos (13,7 ± 1,7 anos) participaram. A LBP foi avaliada por um questionário e a incapacidade pelo Questionário Roland-Morris. A QV foi avaliada pelo Questionário Pediátrico sobre Qualidade de Vida (PedsQL). As análises de variância e de covariância multivariadas foram usadas para avaliar as diferenças entre os grupos. RESULTADOS: As meninas relataram maior incapacidade do que os meninos (p = 0,01) e menor QV nos domínios de funcionamento físico (p < 0,001) e emocional (p < 0,01), no escore sumário de saúde psicossocial (p = 0,02) e saúde física (p < 0,001) e no escore total no PedsQL (p < 0,01). O peso das mochilas escolares era semelhante para ambos os sexos (p = 0,61) e para os participantes com e sem LBP (p = 0,15). Após ajustes, os participantes com LBP relataram menor funcionamento físico (p < 0,01), o que influenciou um menor escore sumário de saúde física (p < 0,01). CONCLUSÕES: As meninas tiveram maior incapacidade e menor QV do que os meninos nos domínios de funcionamento físico e emocional, nos escores sumários de saúde psicossocial e física e no escore total no PedsQL; contudo, foi relatado um peso semelhante das mochilas escolares. Os participantes com LBP revelaram menor funcionamento físico e escore sumário de saúde física, mesmo carregando mochilas escolares de mesmo peso do que aqueles sem LBP. .
