title: Nocturnal eating predicts tooth loss among adults: results from the Danish MONICA study.
abstract: The relationship between nocturnal eating, such as that associated with night eating syndrome (NES), and oral health is unknown. This study sought to determine if nocturnal eating is related to tooth loss in a large, epidemiologic sample. Danes (N=2217; age range 30-60 years, M BMI [kg/m(2)]=25.9, % Male=50.1) enrolled in the Danish MONICA (MONItoring trends and determinants of CArdiovascular disease) were assessed on oral health, eating behavior, anthropometrics, general health, and demographic characteristics in both 1987/88 and 1993/94. We hypothesized that nocturnal eating at time one (1987/88) predicts number of missing teeth at time two (1993/94), when controlling for age, education, smoking status, body mass, carbohydrate intake, binge eating behavior, and diabetes diagnosis. A negative binomial model predicting number of missing teeth from nocturnal eating while controlling for covariates was conducted. Expected change in log count of missing teeth was significantly less for non-night eaters (p=.009), non-smokers (p=.001), non-diabetics (p=.001) and for each successive younger age group (p=.0001). Additionally, expected increase in log count of missing teeth was significantly greater for individuals with less than "high school diploma" education compared to those with the highest level of education (p=.0001). In sum, nocturnal eating contributes to tooth loss. Treatment providers should encourage good oral health care practices to reduce the risk of tooth loss associated with nocturnal eating.
