The relationships among consumption of fruits, tooth loss and obesity
Objective:
to explore whether consumption of fruits attenuates the relationship between tooth loss and obesity among adult Americans.
Basic Research Design:
data from the Behavioral Risk Factor Surveillance System 2012, a cross-sectional survey.
Participants:
20,103 adults aged 18 and over who participated in the Behavioral Risk Factor Surveillance System 2012, a nationally representative survey of non-institutionalized adult American.
Main Outcome Measures:
Obesity (Body Mass Index ≥ 30 kg/m²). Logistic regression analysis was used to assess the association between obesity and number of missing teeth adjusting for consumption of fruits socio-demographic factors, physical activity, diabetes and self-rated general health.
Results:
The prevalence of obesity was higher among adults with ⟩ 6 missing teeth and among those with fruit intakes less than once a day. Individuals with ⟩ 6 missing teeth were at higher risk of obesity with odds ratios 1.25 (95% CI: 1.04, 1.50), the relationship attenuated after adjusting for fruit consumption.
Conclusions:
Frequent consumption of fruits was inversely associated with each of obesity and number of missing teeth. The findings imply a mediating role of fruit consumption in the relationship between tooth loss and obesity.
