SUMMARY:

Introduction: The negative changes that affect children and adolescents living with HIV and using ART can influence the performance of postural control and physical fitness related to the health of this population. Objective: to assess and monitor over time the physical fitness, postural control and level of physical activity of children and adolescents with HIV, while comparing with uninfected peers. Methods: This is a mixed method study in two phases. In the observational cross-sectional study (first phase); 32 children and adolescents participated; 18 in the HIV + group and 14 with negative serology; and in the second phase, a prospective (longitudinal) cohort study took place with three analyzes (1st, 2nd and 3rd) where the initial sample was 18 children and adolescents with HIV, but sample loss resulted in 10 participants. Children and adolescents of both sexes were included in medical follow-up, and those with negative responses to the Physical Activity Readiness Questionnaire were excluded. The following were applied: structured anamnesis containing sociodemographic and clinical data; questionnaire on level of habitual physical activity; body composition was assessed by anthropometry and DXA; biological maturation by mathematical equations and Tanner's scale; postural control, using a force platform, where a bipedal erect posture was maintained with the following conditions: with vision; without vision and with vision and on foam; flexibility using Wells Bench; strength by handgrip test with a dynamometer; and cardiorespiratory capacity on a treadmill with ramp test. Results: in phase 1, comparing the physical fitness of HIV + children and adolescents with HIV- it was identified that only the ventilatory threshold 1 showed a significant difference, indicating that the HIV + group has lower values in cardiorespiratory fitness when compared to their peers; also, when the postural control of both groups (HIV + and HIV-) was compared, in the time domain variables, higher values were observed for the HIV + group in the mean anterior-posterior (p = 0.001) and medium-lateral speed (p = 0.001), as well as in the anteroposterior (p = 0.001) and medium-lateral perimeter (p = 0.001). For the condition factor, a difference was observed for mean amplitude of anteroposterior oscillation (0.039); and when the spectral domain was analyzed, for the group factor, higher values were observed in the HIV + group in the predominant mid-lateral frequency (p = 0.04) and mean anteroposterior frequency (p = 0.001). For the condition factor, a difference was found only in the predominant anteroposterior frequency (p = 0.001); the highest values were in the condition without vision, when compared to the condition with foam. In phase 2, during the long-term follow-up of the HIV + group, it was found that the level of physical activity was maintained over time. The postural control underwent positive changes in the condition without vision, where differences were found between the 1st analysis in relation to the 2nd and 3rd in the mean mediate-lateral (p = 0.01), anteroposterior-posterior (p = 0.04) and mean speed -lateral (p = 0.00); this was also found in the 2nd and 3rd analyzes, and from the moment of the 2nd analysis in relation to the 3rd. In the foam condition, there was a difference in the area (p = 0.02) and medium-lateral perimeter (p = 0.03), both from the moment of the 1st analysis in relation to the 2nd and 3rd. Between the 2nd and 3rd analyzes, there was a difference only in the variable medium-lateral perimeter (p = 0.03). There was also a difference in the optimal cardiorespiratory point in the period of the 1st analysis in relation to the 2nd and 3rd analyzes (p = 0.01). Conclusion: It is concluded that parameters of growth and development, especially body mass and Body Mass Index, influence physical fitness, indicating impairments in the cardiorespiratory fitness of children and adolescents with HIV; and that the postural control performance of the HIV group is inferior to their peers without infection. However, the maintenance of the level of physical activity has a positive influence over time on parameters of postural control and cardiorespiratory optimum point of children and adolescents with HIV infection.
