Sedentary behavior, increasing age, and overweight/obesity increase the presence and intensity of the chronic joint pain in individuals affected by Chikungunya fever.

ABSTRACT

BACKGROUND: Chikungunya fever (CF) is a viral disease, transmitted by alphavirus through Aedes aegypti, and albopictus mosquitoes, affecting several people, mainly in tropical countries, when its transmitter is not under control, and the main symptom of the chronic phase of CF is joint pain. OBJECTIVES: The primary objective of this study was to observe the prevalence, most affected joints, and intensity of chronic joint pain in individuals affected by CF, and also identify the factors associated with chronic joint pain in these individuals. METHODS: Cross-sectional study that evaluated one hundred and thirty volunteers, of both sexes, aged between 20-65 years, with a clinical and/or laboratory diagnosis of CF. The presence of joint pain was investigated using the Brazilian version of the Nordic Questionnaire of Musculoskeletal Symptoms and the intensity of pain using the Visual Analogue Scale. RESULTS: Of the 130 volunteers evaluated, n = 112 (86%) reported currently experiencing chronic joint pain, persistent, for approximately 38.6 ± 1.73 months, with the greatest predominance in the morning (58%). The joints most affected by pain were the ankles (65.5%), interphalangeal joints of the hands (59.2%), and knees (59.2%). The joints that presented the greatest intensity of pain were the ankles (5.13 ± 0.34), interphalangeal joints of the hands (4.63 ± 0.34), and knees (4.33 ± 0.33). Sedentary behavior (p = 0.037), increasing age (p = 0.000), and overweight/obesity (p = 0.002) were factors associated with chronic joint pain. CONCLUSION: A high prevalence of chronic, persistent joint pain was observed, with a greater prevalence in the morning. The joints most affected by chronic pain and with the greatest pain intensity were the ankles, and interphalangeal joints of the hands and knees. Sedentary behavior, increasing age, and overweight/obesity were the factors associated with chronic joint pain in individuals affected by CF in this study. Key Points • Individuals affected by CF had a high prevalence of chronic joint pain, persistent and more prevalent in the mornings • The ankles and interphalangeal joints of the hands and knees were the joints with the highest prevalence of pain • The ankles and interphalangeal joints of the hands and knees were the joints with the greatest pain intensity • Sedentary behavior, increasing age, and overweight/obesity were factors associated with chronic joint pain in individuals affected by CF.
