| Abstract |
While sexual partner age disparity is frequently considered as a potential risk factor for HIV among young women in Africa, no research has addressed this question among older women. Our aim was thus to determine whether sex partner age disparity was associated with subsequent HIV acquisition in women over 30 years of age. To achieve this aim we conducted a quantitative analysis of a population-based, open cohort of women in rural KwaZulu-Natal, South Africa (n = 1,737) using Cox proportional hazards models. As partner age rose, HIV acquisition risk fell significantly: compared to a same-aged partner, a 5-year older partner was associated with a one-third reduction [hazard ratio (HR) 0.63, 95 % CI 0.52-0.76] and a 10-year older partner with a one-half reduction (HR 0.48, 95 % CI 0.35-0.67) in acquisition risk. This result was neither confounded nor effect-modified by women's age or socio-demographic factors. These findings suggest that existing HIV risk-reduction campaigns warning young women about partnering with older men may be inappropriate for older women. HIV prevention strategies interventions specifically tailored to older women are needed. |

Attention Score in Context
This research output has an Altmetric Attention Score of 4. 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 14 September 2022.
All research outputs
#7,079,214
of 23,849,058 outputs
Outputs from AIDS and Behavior
#1,151
of 3,566 outputs
Outputs of similar age
#97,037
of 362,427 outputs
Outputs of similar age from AIDS and Behavior
#15
of 44 outputs
Altmetric has tracked 23,849,058 research outputs across all sources so far. This one has received more attention than most of these and is in the 70th percentile.
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 gotten more attention than average, scoring higher than 67% 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 362,427 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 73% of its contemporaries.
We're also able to compare this research output to 44 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 65% of its contemporaries.
