科学领域:

  • 环境健康 环境健康
  • 遗传学 是一个遗传学.
  • 流行病学 流行病学

背景情况:

  • 衰老是许多人类疾病的重要危险因素.
  • 遗传和表观遗传生物标志物,包括端粒长度 (TL) 和表观遗传钟,对于评估生物衰老和疾病风险至关重要.
  • 暴露组,包括社会经济因素,生活方式,污染和早期生活经历,加速生物衰老,在拉丁美洲的研究有限.

研究的目的:

  • 系统地审查各种暴露因子与拉丁美洲人口中的TL或表观遗传钟生物标志物之间的关系的证据.
  • 解决有关暴露基对生物衰老影响的研究缺口,在一个健康风险因素负担很高的地区.

主要方法:

  • 在PubMed,Scopus和SciELO中按照PRISMA指南进行了系统的文献搜索.
  • 关键词包括健康的社会决定因素,生活方式行为,污染,早期生活经历和特定的拉丁美洲国家,以及端粒长度和表观遗传钟.

主要成果:

  • 分析了来自八个拉丁美洲国家的14项观察研究.
  • 表观遗传钟显示了加快的衰老与充足的睡眠和晚睡; 睡眠短暂和久坐的行为在女性表明年龄减缓.
  • 端粒长度 (TL) 与粮食不安全,低教育,童年贫困和吸烟 (较短的TL) 有关,而富含水果/蔬菜的饮食,童年贫困/暴力和暴露与较长的TL有关. 怀孕期间的PM2.5暴露与较短的TL相关.

结论:

  • 本综述提供了对拉丁美洲TL和表观遗传时钟暴露组影响的首次全面总结.
