Factors Affecting Social Health from Young Adults' Perspective: A Qualitative Study

Background

Factors affecting social health, especially in young adults, are among the most important research priorities. Knowledge of social factors affecting young adults' health will lead to understand them in the social context. The present study is aimed to explain the perspective of young adults on social factors affecting health.

Methods

In the present qualitative content analysis study, semi-structured open interviews were conducted through targeted sampling of young volunteers aged 18-30 who were selected from Tehran Province. Interviews were recorded, transcribed, and analyzed. The inclusion criteria for participants were willingness to participate in the study and ability to express their personal experiences. Twenty-one data were collected through collection was done with individual in-depth interviews.

Results

Using this qualitative approach, the present study was conducted to identify factors affecting social health from the perspective of young adults. The analysis led to the extraction of three main categories, each with two or three subcategories: expectations regarding the community, expectations regarding the family, and expectations regarding infrastructures.

Conclusions

Our findings shown that social support considered as effective elements in providing social health of young adults. The evidence on controlling factors should be considered in promoting the social health of specific target groups. The results of the present study could be used for better planning of interventions in youth social health domains.

OxLDL induces vascular endothelial cell pyroptosis through miR-125a-5p/TET2 pathway

Pyroptosis participates in the formation and development of atherosclerosis (As) by promoting inflammatory factor release and is closely related to the stability of atherosclerotic plaque. MicroRNAs can regulate the expression of target genes at the posttranscriptional level. Previous studies have shown that miR-125a-5p increases in hyperlipidemic-hyperglycemic conditions and is involved in apoptosis, but its specific role in pyroptosis and As remains unclear. We propose that miR-125a-5p may be implicated in oxidized low-density lipoprotein (oxLDL)-induced vascular endothelial cells (VECs) pyroptosis and therefore conducted the current study. We observed that miR-125a-5p can inhibit tet methylcytosine dioxygenase 2 (TET2) expression at the posttranscription level, resulting in abnormal DNA methylation, mitochondrial dysfunction, and increased reactive oxygen species production, activated nuclear factor-κB that induces activation of inflammasome and maturation, release of proinflammatory cytokines interleukin (IL)-1β and IL-18, and pyroptosis. Given the role of VECs in vascular physiology, oxLDL-induced VEC pyroptosis may promote the development of As. Our current study reveals a novel pathway associated with pyroptosis program regulation, which comprises miR-125a-5p and TET2 in VECs. Modulation of their expression levels may serve as a potential target for therapeutic strategies of As.
