RÉSUMÉ
PURPOSE: The purpose of this study is to observe the prevalence and intensity of musculoskeletal pain and the quality of life in mothers of children with microcephaly and also to compare the scores of the quality of life domains between mothers who had or did not have musculoskeletal pain. METHODS: This is a cross-sectional study that evaluated mothers of children with a clinical diagnosis of microcephaly, due to congenital Zika virus syndrome, in the state of Pernambuco, northeast region, Brazil. To assess musculoskeletal pain, the Nordic Questionnaire of Musculoskeletal Symptoms was used, pain intensity was assessed by the Visual Analogue Scale and quality of life by the SF-36 Questionnaire. RESULTS: Of the 63 mothers evaluated, 59 (93.7%) reported currently experiencing musculoskeletal pain. The lumbar spine was the body region with the highest prevalence of pain (77.8%), followed by the thoracic spine (57.1%) and cervical spine (50.8%). Pain intensity was higher in the lumbar spine (6.00 ± 0.47), thoracic spine (4.44 ± 0.52) and shoulders (3.81 ± 0.51). The domains that presented the lowest scores in the quality of life assessment were general health status (49.0 ± 3.19), emotional aspects (49.7 ± 5.88) and pain (49.7 ± 2.50). Mothers who had musculoskeletal pain had lower scores in all domains of quality of life assessment compared to mothers who did not have pain, demonstrating significant differences for functional capacity (P = 0.035), physical aspects (P = 0.047) and pain (P = 0.002). CONCLUSION: A high prevalence of musculoskeletal pain was observed in mothers of children with microcephaly, with a higher prevalence and intensity in the lumbar spine. The domains related to physical and emotional health presented the worst scores in the quality of life of the evaluated mothers and the presence of musculoskeletal pain reduced the quality of life of the mothers of children with microcephaly in this study.
