Risk factors for tooth loss in adults: A population-based prospective cohort study.

ABSTRACT: The aim of this study was to identify the risk factors for tooth loss in an extended age group of adults over 4 years. The prospective cohort study assessed adults (20-64 years old) in 2011 and 2015, from Piracicaba, São Paulo, Brazil. The sample selection was planned based on the adult population in the city. The inclusion criteria were randomly selected residences per census tract unit (one adult per household). The exclusion criteria comprised of a physical or psychological state that prevented the achievement of clinical procedures or understanding of the questionnaire. The home oral examination was performed using the index of decayed, missing, and filled teeth (DMFT), the Community Periodontal Index according to the World Health Organization, and visible biofilm. Demographic and socio-economic data, information on health habits, and the use of dental services were obtained by questionnaire. The outcome was a presence incidence of tooth loss, assessed by the difference between Missing teeth (M>0) from DMFT in 2011 and that in 2015. The conceptual theoretical model 'Ethnicity, aging and oral health outcomes' was adapted for tooth loss and used in a Hierarchical multivariate Poisson Regression analysis (p<0.20). The reference category for the Poisson regression were individuals who had no missing teeth (M) due to caries or periodontal disease (p<0.05). There were a total of 143 (follow-up rate = 57.7%) participants in the four-year study, and there was incidence of tooth loss in 51 (35.7%) adults over this period. The risk factors for tooth loss were reason for seeking dental services by pain (RR = 2.72; 95.0% CI: 1.04-7.37), previous tooth loss (RR = 3.01; 95.0% CI: 1.18-7.73) and decayed teeth (RR = 2.87; 95.0% CI: 1.22-6.73). The risk factors for tooth loss were: reason for seeking dental services by pain, previous tooth loss and dental caries.

Project description:BACKGROUND:Increasing evidence suggests that sleep duration is associated with risks of various diseases including type 2 diabetes, cardiovascular disease (CVD), and certain types of cancer. However, the relationship with mortality is not clear, particularly in non-European populations. In this study, we investigated the association between sleep duration and mortality in a population-based prospective cohort of Korean adults. METHODS:This analysis included 34,264 participants (14,704 men and 19,560 women) of the Korea National Health and Nutrition Examination Survey (KNHANES) 2007-2013 who agreed to mortality follow-up through December 31, 2016. Sleep duration was self-reported at baseline and was categorized into four groups: ?4, 5-6, 7-8, and???9?h/day. Cox proportional hazards models were performed to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the associations with mortality (all-cause as well as CVD- and cancer-specific), adjusting for potential confounders. RESULTS:During up to 9.5?years of follow-up, we identified a total of 1028 deaths. We observed the lowest mortality at 5-6?h/day sleep. Compared with 7-8?h/day of sleep, short (?4?h/day) and long (?9?h/day) sleep were associated with a 1.05-fold (95% CI?=?0.79-1.39) and 1.47-fold (95% CI?=?1.15-1.87) higher all-cause mortality, respectively. After additional adjustment for self-rated health, the positive association with short sleep disappeared (HR?=?0.99, 95% CI?=?0.75-1.32) and the association with long sleep was slightly attenuated (HR?=?1.38, 95% CI?=?1.08-1.76). Long sleep was also nonsignificantly positively associated with both cancer-mortality (HR?=?1.30, 95% CI?=?0.86-1.98) and CVD-mortality (HR?=?1.27, 95% CI?=?0.73-2.21). There was no statistically significant evidence for nonlinearity in the relationships between sleep duration and mortality (all-cause as well as CVD- and cancer-specific). Effect modification by age, sex, education, and occupation were not statistically significant. CONCLUSIONS:Our findings suggest that long sleep duration is associated with an increased all-cause mortality in Korean adults.
