Park, Lee, and Cho: Periodontal Disease and Health Related Quality of Life (HRQoL) in Pregnant Women

Abstract

Purpose

The purpose of this study was to identify relationships of periodontal disease and health related quality of life (HRQoL) in pregnant women.

Methods

The participants in this study were 129 pregnant women. Data were collected using questionnaires of characteristics of the participants and subjective perception of periodontal disease and a dentist's assessment of periodontal disease. Data were analyzed using descriptive statistics, correlation, and hierarchical multiple regression.

Results

The physical QoL showed significant negative correlation with subjective perception of periodontal disease (r=-.21, p=.013). Mental QoL had significant negative correlations with subjective perception of periodontal disease (r=-.32, p<.001) and objective periodontal disease (r=-.34, p<.001). Hierarchical multiple regression analyses revealed that pregnant women who had a history of abortion and had higher subjective perception of periodontal disease tended to report lower levels of physical QoL. Pregnant women whose age are between 30-34 years and higher subjective perception and objective periodontal disease tended to report lower mental QoL.

Conclusion

To improve HRQoL of pregnant women, nurses should pay attention on the status of periodontal disease. Careful assessment of oral healthy behaviors and proper intervention for oral health of pregnant women are needed to enhance HRQoL of pregnant women.

Summary Statement

▪ What is already known about this topic?
Periodontal disease is a common oral infection in pregnant women with high prevalence ranging from 50~75%.
▪ What this paper adds?
This study showed high risk of periodontal disease among pregnant women, reporting 40.3% of gingivitis and 37.2% of periodontitis, which also related to quality of life in pregnant women.
▪ Implications for practice, education and/or policy
Since oral health care is highly related to periodontal disease and quality of life in pregnant women, intensive screening for oral health problems in pregnant women should be considered as routine perinatal care and nationwide advertisement of the important of oral hygiene during pregnancy is essential.
