Female reproduction is associated with physiological, metabolic, and nutritional demands that can negatively affect health and are possibly cumulative when parity is high. While it is probable that maternal oral health is similarly affected, available evidence is based on fairly low parity populations and likely confounders affecting oral health status were not considered.
To determine the relationship between parity and tooth loss in a population with many high parity women. Contributions of age, reproductive and socioeconomic parameters, and oral health practices were considered.
This was a cross-sectional study involving 612 Hausa women of all parity levels aged 13-65 years. Women with ≥5 children were considered high parity. Sociodemographic status and oral health practices were collected using a structured interviewer-administered questionnaire. All teeth present, (excluding third molars) and missing teeth were noted, with inquiries regarding tooth loss etiology. Associations with tooth loss were evaluated through correlations, ANOVA, post hoc analyses and Student's t tests. Effect sizes were used to interpret the magnitude of differences. Multiple regression (negative binomial model) was used to investigate predictors of tooth loss.
Hausa women had a low prevalence of tooth loss, despite poor oral hygiene, and limited dental care. Older, middle SES, and higher parity women experienced significantly more tooth loss. Additionally, increased duration of reproductively active years was significantly related to fewer remaining teeth.
Higher parity was related to greater tooth loss in Hausa women. Women with ≥5 children experienced more loss than lower parity age mates.
女性生殖与生理、代谢和营养需求有关，这些需求可能会对健康产生负面影响，而且在多胎妊娠的情况下可能会累积。虽然母亲的口腔健康可能也会受到类似的影响，但现有证据基于多胎妊娠率较低的人群，并且可能没有考虑到影响口腔健康状况的混杂因素。
在一个多胎妊娠率较高的人群中，确定生育次数与牙齿缺失之间的关系。考虑了年龄、生殖和社会经济参数以及口腔健康行为的影响。
这是一项横断面研究，涉及所有生育水平的 612 名 Hausa 女性，年龄在 13-65 岁之间。生育≥5 个孩子的女性被认为是多胎妊娠。使用结构化访谈员管理的问卷收集社会人口统计学状况和口腔健康行为数据。记录所有存在的牙齿（不包括第三磨牙）和缺失的牙齿，并询问牙齿缺失的病因。通过相关性、方差分析、事后分析和学生 t 检验评估与牙齿缺失的关联。使用效应大小来解释差异的大小。使用多元回归（负二项模型）来研究牙齿缺失的预测因素。
尽管口腔卫生条件差，且牙科保健服务有限，但 Hausa 女性的牙齿缺失率较低。年龄较大、中等社会经济地位和较高生育次数的女性经历了更多的牙齿缺失。此外，生殖活跃年限的延长与剩余牙齿数量的减少显著相关。
生育次数与 Hausa 女性的牙齿缺失相关，生育次数≥5 的女性比生育次数较低的同龄女性牙齿缺失更多。
