Objective: To compare the risk of fetal death on the day of childbirth, with the risk of death at other ages, and with the risks of some hazardous activities, on a common scale of risk per day. Design: Review of publicly available data. Setting: UK. Sample: Data extracted from the Office of National Statistics and other sources. Methods: Data from the Office of National Statistics and other sources were used to calculate death rates at different ages expressed as rates per day of life. Death rates for different activities were also calculated as risks per day, or risks per activity, as appropriate. All risks were expressed in micromorts, the number of one in a million chances of dying. Figures on life expectancy (LE) were used to compare potential life years lost. Main outcome measures: Daily, or unit of activity, risk of dying for different activities compared with the risk of dying on the day of childbirth. Results: The risk of dying on the day of birth (0.43 per 1000, or 430 micromorts) exceeds that of any other average day of life until the 92nd year. It is comparable with other apparently more dangerous activities, such as undergoing major surgery. For comparison, the average risk of non-natural death per day and the increased risk from smoking one cigarette or travelling 200 miles by car are all about 1 micromort. Conclusions: The lifetime risk of death in childbirth is low, but is concentrated in a short period, making being born a high-risk activity. Parents considering interventions to reduce these risks should be made aware of this.

Lengo: Kulinganisha hatari ya kifo cha kiinitete siku ya kuzaliwa, na hatari ya kifo katika umri mwingine, na hatari ya shughuli fulani hatari, kwa kiwango cha kawaida cha hatari kwa siku. Muundo: Mapitio ya data inapatikana kwa umma. Eneo: Uingereza. Mfano: Takwimu zilizochukuliwa kutoka Ofisi ya Taifa ya Takwimu na vyanzo vingine. Takwimu kutoka kwa Ofisi ya Takwimu ya Kitaifa na vyanzo vingine vilitumiwa kuhesabu viwango vya vifo katika umri tofauti, vilivyoonyeshwa kama viwango kwa siku ya maisha. Viwango vya vifo kwa ajili ya shughuli tofauti pia walikuwa mahesabu kama hatari kwa siku, au hatari kwa shughuli, kama inafaa. Hatari zote zilionyeshwa katika micromorts, idadi ya moja katika milioni nafasi ya kufa. Takwimu za muda wa kuishi (LE) zilitumiwa kulinganisha miaka ya maisha iliyopotea. Uwezekano wa kufa kwa siku au kitengo cha shughuli kwa shughuli tofauti ikilinganishwa na hatari ya kufa siku ya kuzaa. Uwezekano wa kufa siku ya kuzaliwa (0.43 kwa kila 1000, au 430 micromort) ni kubwa kuliko siku nyingine yoyote ya maisha hadi miaka 92. Inaweza kulinganishwa na shughuli nyingine zenye kuonekana kuwa hatari zaidi, kama vile kufanyiwa upasuaji mkubwa. Kwa kulinganisha, hatari ya wastani ya kifo kisicho cha kawaida kwa siku na hatari iliyoongezeka kutokana na kuvuta sigareti moja au kusafiri maili 200 kwa gari ni karibu 1 micromort. Uwezekano wa maisha ya kifo katika kuzaa ni chini, lakini ni umakini katika kipindi kifupi, na kufanya kuzaliwa shughuli ya hatari ya juu. Wazazi wanaozingatia uingiliaji ili kupunguza hatari hizi wanapaswa kufahamishwa kuhusu hili.
