使用犹他州人口数据库的历史数据，这项分析发现，对于50岁以上主要有儿子的母亲来说，有显著的、一致的、但很小的不利死亡率影响。对年龄依赖效应的研究表明，这种联系随着母亲年龄的增长而增加。此外，以女儿为主的母亲面临的死亡风险随着年龄的增长而增加。后代的性别组成对父亲的死亡率没有显著影响。交互作用分析被用来检验子女的性别构成对历史时期、居住地点、社会经济地位和童年存活率的影响。没有发现其他交互作用具有统计学意义。无论儿童的存活率如何，以男孩为主的儿童仍然不利于产妇死亡率。
Using historical data from the Utah Population Database, this analysis finds significant, consistent, but small adverse mortality effects for mothers after age 50 who had mostly sons. Examination of age-dependent effects indicates that this association increases with mother's age. Additionally, mothers who had mostly daughters faced mortality risks that increased with age. Offspring sex composition did not have a significant effect on paternal mortality. Interaction analyses were conducted to examine the effect of offspring sex composition with regard to historical period, residential location, socioeconomic status, and childhood survival. No other interactions were found to be statistically significant. Having mostly boys remained detrimental to maternal mortality regardless of childhood survival.
