According to the Bureau of Health Promotion, 2.67 % of pregnant women ages 40-45 whose pregnancies go beyond 20 weeks have stillbirths, and the figure rises to 3.77 % for women ages 45-49. Although those numbers are two to four times higher than the 0.81 % among women ages 25-29, the number of stillborn children still represents a small minority of older women's total births.
根據我國國民健康局 2008 年的統計，產婦年齡為 40 ∼ 45 歲者，懷孕超過 20 周的死產比例約為 2.67 %、45 ∼ 49 歲者為 3.77 %，雖較 25 ∼ 29 歲者（0.81 %）高出 2 ~ 4 倍，但高齡產婦真的因各種母體妊娠疾病而「胎死腹中」者仍屬少數。
