The effect of a brief video-based intervention to improve the ability of AIDS prevention in elderly men: Randomized controlled trial
ABSTRACT
Background:
The AIDS epidemic among older people is becoming more serious. Evidence-based, acceptable and effective preventive interventions are urgently needed to increase their capacity to prevent HIV. Video-based intervention has become an innovative way to change healthy behaviors, and we have developed a brief video-based intervention named Sunset Without AIDS.
Objective:
In this study, we tested the effectiveness of a brief video-based intervention targeting older men's ability of AIDS prevention.
Methods:
A randomized controlled trial was conducted from June 20 to July 3, 2023. The older men were randomly divided into the intervention group (n=50) and the control group (n=50) by the envelope extraction method. The intervention group was given the Sunset Without AIDS video; the control group was received a normal AIDS education video. A questionnaire was used to measure the effect of the Sunset Without AIDS after two interventions. AIDS-related high-risk behaviors were followed up 1 and 3 months after the intervention. The difference was statistically significant at P≤0.05.
Results:
After two interventions, the total awareness rate (%) of AIDS-related knowledge in the intervention group and control group was 84% (42/50) and 66% (33/50), respectively, with P＝0.038. The stigma attitude scores of the two groups were (2.53±0.45) and (2.58±0.49), with P=0.549. The positive scores of attitudes of AIDS-related high-risk behaviors of the two groups were 83.33 (SD 21.56) and 75.67 (SD 26.77), with P=0.58. At 1 and 3 months follow-up after the intervention, participants in two groups did not report AIDS-related high-risk behaviors. After watching the Sunset without AIDS and normal AIDS education video, more people accepted and were satisfied with the Sunset without AIDS.
Conclusions:
Sunset without AIDS could improve the ability of AIDS prevention for older men in China and provide a certain basis for the innovation of AIDS education in the elderly population. Clinical Trial: Chinese Clinical Trial Registry, ChiCTR2100045708. Registered on 23/04/2021.
