Brief Summary

The goal of this clinical trial is to conduct a dietary intervention targeting HIV specific gut microbiota alterations for primary atherosclerotic cardiovascular disease (ASCVD) prevention and evaluate its effectiveness in preventing ASCVD among older people living with HIV (PLWH).

Detailed Description

The investigators utilize a pragmatic randomized controlled trial design to evaluate the effectiveness of dietary intervention in real-world conditions, without strict control, thereby enhancing the generalizability and clinical applicability of our study findings. Participants at Shenzhen Third People's Hospital, exhibiting HIV with CVD risk will be enrolled. Upon providing informed consent, participants will undergo dynamic randomization into intervention and control groups, aiming for a 1:1 ratio while preserving maximum unpredictability. The intervention group will receive the gut microbiota-targeted dietary intervention thrice weekly for 3 months, accompanied by bi-weekly healthy diet guidance for the same duration. Meanwhile, the control group will continue routine follow-up and health education practices. The intervention will span three months, followed by a three-month follow-up period. Data collection will occur at baseline, 3 months, and 6 months. Primary outcomes will assess ASCVD risk via the pooled cohort equation and evaluate gut microbiota diversity and composition. Secondary outcomes will encompass biomarkers and predictors associated with atherosclerotic cardiovascular disease, as well as symptoms related to the condition.

The intervention group will receive the gut microbiota targeted dietary intervention thrice weekly for 3 months, accompanied by bi-weekly healthy diet guidance for the same duration. The intervention will span three months, followed by a three-month follow up period

Group Type: EXPERIMENTAL

dietary intervention

Intervention Type: OTHER

The dietary intervention targeted at gut microbiota. Each participant's dietary habits,food preferences and economic level were taken into account. The dietary intervention was delivered by sending meals. To ensure the freshness and quality of the ingredients, 2 dedicated researchers were jointly responsible for the procurement of fresh ingredients, which were purchased through regular channels on Monday, Wednesday and Friday mornings. Meals will be delivered three times a week for a 12-week intervention period. Guided dietary follow-up was conducted through WeChat or telephone follow-up. The researcher will provide cooking instruction or dietary pattern guidance every two weeks.

control group

The control group will continue routine follow-up and health education practices.
