In three cohorts of 70-yr-olds in Gothenburg, Sweden, born in 1901/02, 1906/07 and 1911/12, the relationship between oral health and parity was studied in 713 women and between oral health and the reported number of children in 660 men of the same cohorts. For women in all three cohorts, the number of teeth decreased in relation to increasing number of children that they had given birth to. Significantly more women with high parity were edentulous in one or both jaws compared to the other groups. Among parous compared to nulliparous women the age for becoming edentulous occurred earlier. The number of intact teeth was lower in parous compared to nulliparous women. Among the men no relation was found between oral health and the number of their children. When socioeconomic factors were taken into consideration the above described relations between declining dental health and increasing parity remained on about the same level of significance. Although pronounced cohort differences were found, a relationship between parity and dental health was found in all cohorts, indicating a general biological influence of repeated pregnancies.
在瑞典哥德堡出生于1901/02年、1906/07年和1911/12年的三组70岁人群中，对713名女性的口腔健康与生育胎次之间的关系以及同组660名男性的口腔健康与所报告的子女数量之间的关系进行了研究。对于所有三组中的女性，牙齿数量随着她们生育子女数量的增加而减少。与其他组相比，高生育胎次的女性中无牙颌或单颌无牙的情况明显更多。与未生育女性相比，经产女性出现无牙的年龄更早。经产女性的完整牙齿数量比未生育女性少。在男性中，未发现口腔健康与子女数量之间存在关联。当考虑社会经济因素时，上述牙齿健康下降与生育胎次增加之间的关系仍保持在大致相同的显著水平。尽管发现了明显的队列差异，但在所有队列中均发现了生育胎次与牙齿健康之间的关系，这表明多次怀孕存在普遍的生物学影响。
