This study investigated the relationship between individual height and survival at older ages among conscripts born between 1866 and 1915 in an inland village of Sardinia, Italy. Individual age at death was related to military height measurement at age 20. Differential longevity of conscripts at older ages was investigated through the comparison of age-specific mortality rates and life expectancy estimates. Results indicated that short conscripts (<161.1 cm) generally had higher survival rates than their tall peers (≥ 161.1 cm). At 70 years of age, tall peers were expected to live two years less than short conscripts. Biological mechanisms were examined in relation to the greater longevity of shorter people.
本研究调查了1866年至1915年出生在意大利撒丁岛一个内陆村庄的应征入伍者中，个体身高与老年生存率之间的关系。死亡时的个体年龄与20岁时的军事身高测量值相关。通过比较特定年龄死亡率和预期寿命估计值，研究了老年应征入伍者的寿命差异。结果表明，矮个子应征入伍者（<161.1厘米）的生存率通常高于高个子同龄人（≥161.1厘米）。在70岁时，高个子同龄人预计比矮个子应征入伍者少活两年。研究了与较矮人群寿命更长相关的生物学机制。
