Trends in the prevalence of periodontitis in Taiwan from 1997 to 2013

Abstract

Periodontitis is one of the most prevalent oral diseases. In this study, we probed the nationwide registered database to assess the time trends of prevalence of periodontitis in Taiwan.A retrospective study was conducted to analyze the registered database compiled by the National Health Insurance provided by the Department of Health, Taiwan, from 1997 to December 2013.We found that the prevalence of periodontitis significantly increased from 11.5% in 1997 to 19.59% in 2013 (P for trend < .0001). The mean age ± standard deviation with periodontitis from 1997 to 2013 was 54.46 ± 14.47 and 45.51 ± 16.58 years old, respectively. The proportion of individuals with periodontitis in age group >65 years old decreased markedly. The proportion of individuals with periodontitis in age groups <25 and 26 to 35 years old demonstrated an increased pattern. Compared to the reference cohort of 1953 to 1957, the recent birth cohort of 1993 to 1997 revealed the highest relative risk (RR) of periodontitis (male: RR, 67.42, 95% confidence interval [CI], 17.04–266.76; female: RR, 65.85, 95% CI, 16.70–259.70). Both male and female groups showed the similar age-effect pattern in the cross-sectional age curve from age–period–cohort model. There was an upturn with advancing age up to 40 to 50 years old and then a downward trend in both genders. Population dwelling in suburban area (RR, 0.95; 95% CI, 0.94–0.97) and rural area (RR, 0.97; 95% CI, 0.95–0.99) had the lower risk of periodontitis than those who lived in urban area. The higher income group revealed the higher risk of periodontitis compared with lower income group (RR, 1.20; 95% CI, 1.18–1.23).The prevalence of periodontitis significantly increased in Taiwan over past 17 years. The mean age with periodontitis was shown in a decreased pattern. The use of a nationwide population-based database could provide sufficient sample size, generalizability, and statistical power to assess the periodontal status in Taiwan.

Periodontitis and dental scaling associated with pyogenic liver abscess: A population‐based case‐control study

“…The US study showed a prevalence of PPD ≥5 mm was 19.6% from 2009 to 2012, and Korea's health protection data showed that the prevalence of periodontitis was 31% from 2002 to 2013 . Moreover, we previously reported that the prevalence rate of periodontal disease in Taiwan increased from 11.5% in 1997 to 19.59% in 2013, and this prevalence rate is similar to this study. Third, liver abscesses are endemic to Southeast Asian countries and Taiwan.…”

“…The source population consisted of nearly the entire population of Taiwan (23 million inhabitants), which was covered by the National Health Insurance (NHI). [ 32 – 34 ] The study used the Longitudinal Health Insurance Database (LHID) obtained from the NHI Research Database (NHIRD), consisting of 1 million beneficiaries randomly sampled from the original NHI beneficiaries. [ 35 , 36 ] The National Health Research Institute in Taiwan permitted the access to the data in the NHIRD and the database includes the entire registry and claims data from this this health insurance system.…”

“…[ 35 , 36 ] The National Health Research Institute in Taiwan permitted the access to the data in the NHIRD and the database includes the entire registry and claims data from this this health insurance system. [ 32 – 37 ] The accuracy of diagnosis in the NIRD has been validated for several diseases, including stroke and CKD. [ 37 – 39 ] To minimize the bias of uncertain diagnosis for GC in the current study, the following strategy was used.…”

Association between Peptic Ulcer Disease and Periodontitis: A Nationwide Population-Based Case-Control Study in Taiwan

“…Asian Americans experienced a mean attachment loss of 1.95 mm and 15.4% had clinical attachment loss (CAL) ≥7 mm [ 6 ]. In addition, a study of PD prevalence in Taiwan showed that the prevalence of PD gradually rose from 11.5% in 1997 to 19.59% in 2013 during the 17-year study period [ 7 ].…”
