Why the study?

Are there sex differences in the prevalence and location of aortic calcification among middle-aged and older adults?

Key Points

To investigate sex- and age-related variations in the anatomical distribution of aortic calcification.
Evaluated 1,828 men and 1,093 women aged 40 to 79 years who attended a hospital between 1969 and 1978.
Identified calcification of the aortic arch and abdominal aorta using routine posteroanterior chest and lateral lumbar radiographs.
Total aortic calcification rates showed no significant difference between men and women across age groups when combining both anatomical sites.
Aortic arch calcification occurred more frequently in women than men across all ages, with significant differences in individuals in their 60s, 70s, and overall total.
Abdominal aortic calcification appeared more frequently in men than women across all ages, reaching statistical significance in individuals in their 40s, 50s, and overall total.

Structured PICO

Are there sex differences in the prevalence and location of aortic calcification among middle-aged and older adults?

P

Population

2,921 patients (1,828 men, 1,093 women) in their 40s to 70s who visited a single hospital between 1969 and 1978

O

Outcome

Sex differences in the frequency and location of aortic calcification (aortic arch vs. abdominal aorta) assessed by routine chest and lumbar X-rayssurrogate

Aortic calcification exhibits distinct sex differences in location, with women more prone to aortic arch calcification and men more prone to abdominal aortic calcification.

Implication

Sex differences in aortic calcification sites may inform risk models; cross-sectional data leave prognostic and therapeutic implications open.

Abstract

1969年～1978年の間に, 当院を受診した. 40歳代～70歳代の男性1,828例, 女性1,093例を対象として, 大動脈石灰化像の年代別, 部位別の性差について検討を行った. 石灰化像はルーチンの胸部背腹方向と, 腰椎側方向のX線写真にて判定した.大動脈石灰化像を, 大動脈弓部, 腹部大動脈, 及びその両者にあるものを, 一括してみると, 各年代ともその出現頻度に男女差はみられなかった. しかし, 大動脈弓部と腹部大動脈を別々にみると, 大動脈弓部では, 各年代とも女性の方が高い出現頻度を示し, 60歳代, 70歳代, 及び全例の合計において, 男女の間に有意差があった. 腹部大動脈では, 各年代とも男性の方が高い出現頻度を示し, 40歳代, 50歳代, 及び全例の合計において有意差がみられた. 石灰化像の認められたものだけについて, 大動脈弓部のみ, 腹部大動脈のみ, 及びその両者ともに石灰化のあるものの3群に分けると, 男性では, 女性に比し, 腹部石灰化の割合が高く, 女性では男性に比し, 弓部石灰化の割合が高く, 70歳代以外では, すべて有意差がみられた.
