Global Prevalence of Periodontal Disease and Lack of Its Surveillance.

ABSTRACT:

Background

Periodontal disease is a public health problem and is strongly associated with systemic diseases; however, its worldwide distribution is not fully understood.

Objective

To evaluate global data of periodontal disease: (1) among adolescents, adults, and older population and (2) in low-, middle-, and high-income countries.

Methods

This ecological study included data of periodontal disease from the World Health Organization's data bank which are based on the Community Periodontal Index of Treatment Needs (CPITN code: 0?=?no disease; 1?=?bleeding on probing; 2?=?calculus; 3?=?periodontal pocket (PD) 4-5?mm; 4?=?PD (6+?mm). Age- and income-related periodontal disease inequalities were evaluated across the globe.

Results

Compared with 9.3% of adults and 9.7% of older persons, 21.2% of adolescents had no periodontal disease (P = 0.005). Nearly 18.8% of adolescents compared with 8.9% of adults and 5% of older persons had bleeding on probing (P ? 0.001). Similarly, 50.3% of adolescents, 44.6% of adults, and 31.9% older persons demonstrated the occurrence of calculus (P = 0.01). On the other hand, older persons had the highest prevalence of PD 4-5?mm and PD 6+ mm than adults and adolescents (P ? 0.001). The distribution of periodontitis (CPITN code 3?+?4) in adults differed significantly in low- (28.7%), lower-middle- (10%), upper-middle- (42.5%), and high-income countries (43.7%) (P = 0.04). However, no significant differences in periodontitis (CPITN code 3?+?4) were observed in adolescents and older persons in low- to high-income countries.

Conclusions

Within the limitations of data, this study found that the distribution of periodontal disease increases with age. Periodontitis was the most common in older persons and in population from high-income countries.

Project description:BackgroundRobust and flexible infectious disease surveillance is crucial for public health. Event-based surveillance (EBS) was developed to allow timely detection of infectious disease outbreaks by using mostly web-based data. Despite its widespread use, EBS has not been evaluated systematically on a global scale in terms of outbreak detection performance.ObjectiveThe aim of this study was to assess the variation in the timing and frequency of EBS reports compared to true outbreaks and to identify the determinants of variability by using the example of seasonal influenza epidemic in 24 countries.MethodsWe obtained influenza-related reports between January 2013 and December 2019 from 2 EBS systems, that is, HealthMap and the World Health Organization Epidemic Intelligence from Open Sources (EIOS), and weekly virological influenza counts for the same period from FluNet as the gold standard. Influenza epidemic periods were detected based on report frequency by using Bayesian change point analysis. Timely sensitivity, that is, outbreak detection within the first 2 weeks before or after an outbreak onset was calculated along with sensitivity, specificity, positive predictive value, and timeliness of detection. Linear regressions were performed to assess the influence of country-specific factors on EBS performance.ResultsOverall, while monitoring the frequency of EBS reports over 7 years in 24 countries, we detected 175 out of 238 outbreaks (73.5%) but only 22 out of 238 (9.2%) within 2 weeks before or after an outbreak onset; in the best case, while monitoring the frequency of health-related reports, we identified 2 out of 6 outbreaks (33%) within 2 weeks of onset. The positive predictive value varied between 9% and 100% for HealthMap and from 0 to 100% for EIOS, and timeliness of detection ranged from 13% to 94% for HealthMap and from 0% to 92% for EIOS, whereas system specificity was generally high (59%-100%). The number of EBS reports available within a country, the human development index, and the country's geographical location partially explained the high variability in system performance across countries.ConclusionsWe documented the global variation of EBS performance and demonstrated that monitoring the report frequency alone in EBS may be insufficient for the timely detection of outbreaks. In particular, in low- and middle-income countries, low data quality and report frequency impair the sensitivity and timeliness of disease surveillance through EBS. Therefore, advances in the development and evaluation and EBS are needed, particularly in low-resource settings.
