Introduction Several studies have shown high prevalences of sedentariness among adolescents, however, studies assessing sedentariness of adolescents with HIV are scarce. The aim of this study is to assess the prevalence of sedentariness in this population and its associated factors.

Methods 91 patients aged 10–19 years responded to the questionnaire on physical activity validated for Brazilian adolescents. The questionnaire is comprised of 17 questions (15 on sports and two on transportation physical activity). The cut-off point for sedentariness was 300 min/week.

Results Mean age at interview was 15.1 years (SD=2.6 years). A greater proportion of girls was sedentary (80%×61%, p<0.05). All other variables tested were not associated with sedentariness: ethnicity (white-65%; non-white-62%, p=0.286); living with family (yes-70%; no-89%, p=0.220); altered waist circumference (yes-70%; no-72% p=0.881) and overweight (yes-0%; no-8%, p=0.081). No differences between means of biochemical parameters were found when comparing active and sedentary adolescents: viral load (15995×15922 copies, p=0.995); CD4 (485×441 cells, p=0.540); total cholesterol (156×162 mg/dl, p=0.523); HDL-cholesterol (39×37 mg/dl, p=0.373) and LDL-cholesterol (94×95 mg/dl, p=0.874). 1/3 of adolescents spent no time practicing physical activity. Among those who reported practicing it, the sports most cited were: football (44.4%), volleyball (14.4%) and cycling (7.8%). Mean time spent practicing sports was 198.9 min/week (SD=271.1 minutes) and mean time spent walking/cycling to school was 74.1 min/week (SD=104.2).

Conclusion A high prevalence of sedentariness was found in this population. Sedentary behaviour may have a negative impact on adolescents' health.
