粮食不安全与代谢健康状况不佳有关,但饮食因素如摄入量和质量不能完全解释这种联系. 其他社会决定因素也可能发挥重要作用.
科学领域:
- 营养科学 营养科学
- 公共卫生 公共卫生
- 代谢健康研究 代谢健康研究
背景情况:
- 粮食不安全 (FI) 被认为是代谢健康不良的重要决定因素.
- 现有假设表明,能量摄入量和饮食质量是这种关联的主要驱动因素.
- 了解饮食因素的调解作用对于公共卫生干预至关重要.
研究的目的:
- 调查饮食数量和质量是否调解粮食不安全 (FI) 与代谢健康不良结果之间的关系.
- 检查FI与超重,腰围和血糖控制 (血红蛋白A1C) 的关联.
主要方法:
- 调解分析是使用国家健康和营养检查调查 (NHANES) 的数据进行的.
- 粮食不安全 (FI) 作为独立变量.
- 体重指数 (BMI),腰围和血红蛋白A1C (A1C) 是代谢结果的变量.
- 总能量摄入量,宏观营养素和健康饮食指数-2015 (HEI-2015) 被评估为潜在的调解因素.
主要成果:
- 尽管在粮食不安全的个体中肥胖率更高,但在粮食安全和粮食不安全组之间,每日能量摄入量没有显著差异.
- 总的来说,在调整后的分析中,检查的饮食因素并没有调解FI和代谢结果之间的关联.
- 种族分层分析显示,在某些族群 (非西班牙裔白人和"其他") 中,糖消费和饮食质量具有特定的调解作用.
结论:
- 饮食因素不是粮食不安全与代谢健康之间的关联的主要调解因素.
- 需要进一步的研究来探索与FI相关的其他健康社会决定因素的影响.
- 识别非饮食因素对于制定有效的策略来减轻粮食不安全对健康的影响至关重要.
