Abstract

Background: Neck circumference (NC) has been associated with mortality secondary to cardiovascular diseases and other conditions. However, information on this association in the population at large is limited. We aimed to assess this association in community dwellers living in rural Ecuador.

Methods: Individuals aged ≥40 y who were enrolled in the population-based Three Villages Study cohort were prospectively followed to estimate mortality risk according to baseline measurements of NC, after adjusting for relevant confounders.

Results: Analysis included 1521 individuals followed for a mean of 6.4±3.4 y. Mean NC was 36.2±3.7 cm, with 509 (33%) individuals allocated to the first (25-34 cm), 319 (21%) to the second (36-37 cm), 417 (27%) to the third (37-39 cm) and 276 (18%) to the fourth (40-50 cm) quartile. A total of 211 (14%) individuals died during the follow-up. Overall, the crude mortality rate was 2.3 per 100 person-years, which increased to 5.63 for those in the fourth NC quartile. An adjusted Cox-proportional hazards model showed that individuals in the fourth quartile of NC had higher mortality risk compared with the first quartile (HR: 2.98; 95% CI 1.77 to 5.02).

Conclusion: Larger NC increases mortality risk in middle-aged and older adults of indigenous ancestry living in rural Ecuador.

颈围是厄瓜多尔农村地区中老年人全因死亡率的预测指标。

背景：颈围（NC）与继发于心血管疾病和其他疾病的死亡率有关。然而，有关这种关联在整个人口中的信息却很有限。我们的目的是评估厄瓜多尔农村社区居民的颈围与死亡率的关系：方法：我们对 "三村研究 "人群中年龄≥40 岁的个体进行了前瞻性随访，在对相关混杂因素进行调整后，根据数控基线测量值估算死亡风险：平均NC为36.2±3.7厘米，其中509人（33%）被分配到第一四分位数（25-34厘米），319人（21%）被分配到第二四分位数（36-37厘米），417人（27%）被分配到第三四分位数（37-39厘米），276人（18%）被分配到第四四分位数（40-50厘米）。共有 211 人（14%）在随访期间死亡。总体而言，粗死亡率为每 100 人年 2.3 例，第四个 NC 四分位数的粗死亡率上升到 5.63 例。调整后的 Cox 比例危险模型显示，与第一四分位数的人相比，第四四分位数 NC 的人的死亡风险更高（HR：2.98；95% CI 1.77 至 5.02）：结论：NC越大，厄瓜多尔农村原住民中老年人的死亡风险越高。
