The role of fruit and vegetable intake in relation to fracture prevention during adulthood and beyond is not adequately understood. We investigated the potential association between fruit and vegetable intake and hip fracture incidence in a large sample of older adults from Europe and the United States. A total of 142,018 individuals (116,509 women) aged ≥60 years, from five cohorts, were followed up prospectively for 1,911,482 person-years, accumulating 5552 hip fractures. Fruit and vegetable intake was assessed by validated, cohort-specific, food-frequency questionnaires (FFQ). Ηip fractures were ascertained through national patient registers or telephone interviews/questionnaires. Adjusted hazard ratios (HRs) derived by Cox proportional hazards regression were estimated for each cohort and subsequently pooled using random effects meta-analysis. Intake of ≤1 serving/day of fruit and vegetables combined was associated with 39% higher hip fracture risk (pooled adjusted HR, 1.39; 95% confidence interval [CI], 1.20 to 1.58) in comparison with moderate intake (>3 and ≤5 servings/day) (pfor heterogeneity = 0.505), whereas higher intakes (>5 servings/day) were not associated with lower risk in comparison with the same reference. Associations were more evident among women. We concluded that a daily intake of 1 or <1 servings of fruits and vegetables was associated with increased hip fracture risk in relation to moderate daily intakes. Older adults with such low fruit and vegetable consumption may benefit from raising their intakes to moderate amounts in order to reduce their hip fracture risk. © 2016 American Society for Bone and Mineral Research.
水果和蔬菜摄入量在成年期及之后预防骨折方面的作用尚未得到充分了解。我们在来自欧洲和美国的大量老年人样本中,研究了水果和蔬菜摄入量与髋部骨折发生率之间的潜在关联。来自五个队列的总共142,018名年龄≥60岁的个体(116,509名女性),进行了前瞻性随访,随访时间达1,911,482人年,共发生5552例髋部骨折。水果和蔬菜摄入量通过经过验证的、特定队列的食物频率问卷(FFQ)进行评估。髋部骨折通过国家患者登记或电话访谈/问卷确定。通过Cox比例风险回归得出的调整后风险比(HR)针对每个队列进行估计,随后使用随机效应荟萃分析进行汇总。与中等摄入量(>3份且≤5份/天)相比,水果和蔬菜总摄入量≤1份/天与髋部骨折风险高39%相关(汇总调整后HR,1.39;95%置信区间[CI],1.20至1.58)(异质性p = 0.505),而与相同参考相比,较高摄入量(>5份/天)与较低风险无关。这种关联在女性中更为明显。我们得出结论,与中等日摄入量相比,每日摄入1份或不足1份水果和蔬菜与髋部骨折风险增加相关。水果和蔬菜摄入量如此低的老年人可能会受益于将摄入量提高到中等水平,以降低其髋部骨折风险。© 2016美国骨与矿物质研究学会
