 note = {Background: We investigated the association between psychological distress and oral health status/oral healthrelated quality of life (OHQoL) in Japanese community-dwelling people.
Methods: We conducted a cross-sectional study using data from the Nagasaki Islands Study. A total of 1183 (455 men and 728 women) has been analyzed in this study. Psychological distress was measured using the Kessler Psychological Distress Scale (K6). Oral health status was measured by dental examination. The OHQoL was measured using the General Oral Health Assessment Index (GOHAI). We defined the total score of ≥5 points on the K6 as high psychological distress (high-K6 group).
Results: The multiple linear regression analysis to identify the GOHAI showed that gender, K6, the total number of teeth, the number of dental caries, and visiting a dental clinic within the past 6 months significantly associated with the GOHAI. Among all of these variables, high-K6 (≥ 5) was a substantial contributing factor of the GOHAI
(β = − 0.23, 95% Cl − 2.31 to −1.41, p < 0.0001).
Conclusions: It is likely that the individual with high psychological distress was strongly related to poor OHQoL even in the general population., 長崎大学学位論文 学位記番号:共博(医歯薬)甲第6号 学位授与年月日:令和3年3月22日, Author: Ai Sekiguchi, Shin-ya Kawashiri, Hideaki Hayashida, Yuki Nagaura, Kenichi Nobusue, Fumiaki Nonaka, Hirotomo Yamanashi, Masayasu Kitamura, Koji Kawasaki, Hideki Fukuda, Takahiro Iwasaki, Toshiyuki Saito and Takahiro Maeda, Citation: Environmental Health and Preventive Medicine, 25, art.no.82; 2020, Nagasaki University (長崎大学), 博士(医学) (2021-03-22)},
