Does reduced oral functionality influence weight gain?
Investigators explored the relationship between tooth loss and weight gain.
In a study published in the Journal of Periodontology, the investigators used data from the Health, Aging and Body Composition Study to examine whether the number of teeth, functional tooth units and periodontal status were correlated with weight change in more than 900 older adult participants who underwent oral health examinations. Weight gain was defined as an increase of 5% of more of the participants’ body weight.
The investigators noted that over 25% and 11% of the study participants experienced weight loss and weight gain, respectively. After a period of four years, factors such as clinical attachment loss; the number of teeth; and molar, posterior and total functional tooth units were associated with weight gain. For instance, those with tooth loss — particularly missing molars — or poorer chewing function were more likely to gain weight.
The investigators proposed that individuals who present with these factors could have altered eating habits that increase their risk of weight gain. Despite the findings, they indicated that further studies assessing the mechanisms underlying the connection between weight gain and tooth-related changes will be needed.
In a news article from HealthDay reporting on the study, experts explained that individuals with healthy teeth and gums are more likely to follow healthful diets rich in whole fruits and vegetables that lead to a greater quality of life. They further highlighted that the study could add to a growing body of evidence that oral health is integral in supporting a healthy weight and good systemic health.
