Time-restricted eating (TRE) has emerged as a dietary strategy that restricts food consumption to a specific time window and is commonly applied to facilitate weight loss. The benefits of TRE on adipose tissue have been evidenced in human trials and animal models; however, its impact on bone tissue remains unclear. To systematically synthesize and examine the evidence on the impact of TRE on bone health (bone mineral content (BMC), bone mineral density (BMD), and bone turnover factors), PubMed, Scopus, Cochrane CENTRAL, and Web of Science databases were systematically explored from inception to 1 October 2023 searching for randomized controlled trials (RCTs) aimed at determining the effects of TRE on bone health in adults (≥18 years). The Cochrane Handbook and the PRISMA recommendations were followed. A total of seven RCTs involving 313 participants (19 to 68 years) were included, with an average length of 10.5 weeks (range: 4 to 24 weeks). Despite the significant weight loss reported in five out of seven studies when compared to the control, our meta-analysis showed no significant difference in BMD (g/cm) between groups (MD = -0.009, 95% CI: -0.026 to 0.009, = 0.328; = 0%). BMC and bone turnover markers between TRE interventions and control conditions were not meta-analyzed because of scarcity of studies (less than five). Despite its short-term benefits on cardiometabolic health, TRE did not show detrimental effects on bone health outcomes compared to those in the control group. Nevertheless, caution should be taken when interpreting our results due to the scarcity of RCTs adequately powered to assess changes in bone outcomes.
限时进食(TRE)作为一种饮食策略,限制食物摄入到特定的时间窗口,通常用于促进体重减轻。TRE 对脂肪组织的益处已在人体试验和动物模型中得到证实;然而,其对骨骼组织的影响尚不清楚。为了系统地综合和检查关于 TRE 对骨骼健康(骨矿物质含量(BMC)、骨矿物质密度(BMD)和骨转换因子)影响的证据,从成立到 2023 年 10 月 1 日,系统地在 PubMed、Scopus、Cochrane CENTRAL 和 Web of Science 数据库中搜索旨在确定 TRE 对成年人(≥18 岁)骨骼健康影响的随机对照试验(RCT)。遵循 Cochrane 手册和 PRISMA 建议。共纳入了 7 项涉及 313 名参与者(19 至 68 岁)的 RCT,平均长度为 10.5 周(范围:4 至 24 周)。尽管在五分之五的研究中与对照组相比体重显著减轻,但我们的荟萃分析显示,组间 BMD(g/cm)无显著差异(MD=-0.009,95%CI:-0.026 至 0.009,=0.328;=0%)。由于研究数量较少(少于 5 项),因此未对 TRE 干预与对照条件之间的 BMC 和骨转换标志物进行荟萃分析。尽管 TRE 在短期内心血管代谢健康方面有好处,但与对照组相比,它对骨骼健康结果没有不良影响。然而,由于缺乏足够的 RCT 来评估骨骼结果的变化,因此在解释我们的结果时应谨慎。
