HIV infection is associated with poorer physical performance, say researchers in the online edition of AIDS Journal. It was also found that people living with HIV and having reduced physical activity had a significant increase in their risk of death.
The study population consisted of patients seropositive for HIV in middle age and seronegative patients also in middle-aged people in Baltimore, United States, whether they were or not, injecting drug users (IDUs).
"Our results show the great impact of HIV disease on physical performance, support the growing recognition and importance of chronic HIV disease in middle age with the results and can inform and form strategies for clinical management of aging in people infected HIV, "comment the authors.
Thanks to improvements in treatment and care for HIV-positive people, a large porçãocada increasingly growing of people living with HIV are chegandoa increasingly advanced ages. This means, in short, that the diseases of aging are, nowadays, a major cause of death in these patients; deaths can be avoided or at least postponed
Reduced physical activity is associated with an increased risk of mortality among the elderly in relation to the general population. As a function of the lower body - balance ability, walking speed and difficulty getting up from a sitting position - this can be assessed using a short battery performance physical battery test (SPPB). In the general population, the SPPB score below ten is associated with an increased risk of access to nursing care and mortality.
Using SPPB, researchers wanted to see whether carrying HIV could be associated with less physical function. They also wanted to see if performance
had an association with risk of mortality in people living with HIV / AIDS.
Thus, it assessed prospectively the physical performance and the risk of mortality in a cohort of HIV-positive 1627 current risk and former injection drug users. Physical performance was measured every six months. The follow-up study took place between the years 2005 and 2010, and participants contributed a total of 12.270 study visits.
The participants had an average age of 51 years, most african-Americans and a third made up of women.
Participants living with HIV contributed 3715 study visits (30%). The median count of CD4 and viral load were 340 cells / mm3 and 70 copies / ml, respectively.
The SPPB scores with ten or fewer points accounted for a third of the study visits.
After taking into account possible confounding factors, HIV infection was independently associated with an increase of 30% risk of a SPPB score of ten or below (OR = 1,30, 95 -1,12 IC1.52%).
During the monitoring period, 165 patients (10%) died. This means that the death rate was 2,75 100 by person-years.
The SPPB Score of the ten points or below was associated with an 2,3 score in the increased risk of mortality compared to a higher SPPB score (HR 2,34; XXUMUMX% 95-1,67). For HIV-negative patients, lower-score SPPB was associated with an 3,27-double (IC 2.21%, 95 -1,37) increase in risk of mortality, compared to one between 3,55-double (IC 2,55%, 95 -1,33) increase in HIV-positive patients to people with poorly controlled HIV, and 4.76-fold (IC 2,02%, 95 -0,95) increase of all other HIV-positive individuals.
HIV infection alone was associated with almost three times more at risk of mortality (HR = 2,78, 95 -1,70 IC4.54%).
The authors found that the lower physical performance and HIV infection had a joint effect on the risk of mortality.
People living with HIV and who had low scores SPPB had a six-fold increase (HR = 6,03, 95 -3,80 IC10,0%) in the risk of death during follow-up period compared to HIV-negative individuals with higher SPPB score.
"Our findings reinforce the need to integrate the principles as functional geriatric assessment to the care of older people infected with HIV," the authors conclude. "The SPPB pontuaçãoo can be an effective tool for use in clinical research and clinical / therapeutic settings to support healthy aging of people with HIV infection."
