Family relationships, perceived stigma, and social isolation among people living with HIV/AIDS: a cross-sectional study in China.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSocial isolation is a critical determinant of health that disproportionately affects people living with HIV/AIDS (PLWHA). Although existing literature has identified associations of family relationships and perceived stigma with social isolation, the ways in which these factors are statistically related remain insufficiently explored. This study aimed to assess the level of social isolation among PLWHA in China and to examine whether perceived stigma is statistically associated with the relationship between family relationships and social isolation.
methodsA cross-sectional study was conducted among 294 PLWHA recruited through convenience sampling from Chengdu Public Health Clinical Center and the Xichang Center for Disease Control and Prevention between March 2023 and July 2024. Participants completed questionnaires on sociodemographic variables, disease-related information, General Alienation Scale, Berger HIV Stigma Scale, and Family Intimacy and Adaptability Scale. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson correlation, and Bootstrap mediation analysis (PROCESS Model 4) in SPSS 27.0.
resultsA total of 294 PLWHA (78.9% male; mean age 42.31 years) were included in the analysis. Participants reported relatively high levels of social isolation (mean = 41.46 ± 7.25). Family relationships were negatively associated with perceived stigma (r = − 0.300, p < 0.01) and social isolation (r = − 0.623, p < 0.01), while perceived stigma was positively associated with social isolation (r = 0.478, p < 0.01). Mediation analysis indicated that perceived stigma was statistically associated with the relationship between family relationships and social isolation (indirect association = − 0.033, 95% CI [− 0.051, − 0.018]), accounting for 15.1% of the total association.
conclusionSocial isolation remains a prominent concern among PLWHA. Family relationships are associated with lower levels of social isolation, and this association is partially linked to perceived stigma. These findings highlight the potential importance of addressing both family support and perceived stigma in future research and intervention development. However, given the cross-sectional design, the findings should be interpreted as associational rather than causal.
