| Abstract |
Higher levels of physical activity (PA) have been linked to better neurocognitive functioning in many populations. The current study examines the longitudinal association between PA and neurocognitive functioning among HIV-infected and HIV-uninfected persons. Community-dwelling adults (N = 291) self-reported level of PA and completed a comprehensive neuropsychological battery at two to four study visits (Mean follow-up time = 2.6 years). Participants were divided into three PA groups: "No PA" (no PA at any visit), "consistent PA" (PA at ≥50% of visits), and "inconsistent PA" (PA < 50% of visits). A mixed effect model, adjusting for significant covariates showed that all PA groups had statistically significant, yet modest, neurocognitive decline over time; and, the consistent PA group began with, and maintained, significantly better neurocognitive function compared to the other two PA groups. This effect was evident among both HIV-uninfected and HIV-infected persons, despite the fact that HIV-infected persons showed lower baseline neurocognitive function. PA is a modifiable lifestyle behavior that may help to protect against neurocognitive impairment regardless of HIV status, however, given the proportion of HIV-infected individuals who evidence neurocognitive difficulties, a focus on increasing PA seems warranted. |

Attention Score in Context
This research output has an Altmetric Attention Score of 31. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 December 2017.
All research outputs
#1,146,238
of 23,849,058 outputs
Outputs from AIDS and Behavior
#118
of 3,566 outputs
Outputs of similar age
#25,070
of 425,011 outputs
Outputs of similar age from AIDS and Behavior
#5
of 98 outputs
Altmetric has tracked 23,849,058 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 95th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,566 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.0. This one has done particularly well, scoring higher than 96% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 425,011 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 94% of its contemporaries.
We're also able to compare this research output to 98 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 94% of its contemporaries.
