Tooth loss severity and core and non‐core food consumption among older Brazilian adults

摘要

Objective To investigate the association between tooth loss severity and core and non‐core food consumption in the older Brazilian population. Methods We analysed data from 20?756 people aged 60?years or older who participated in the 2019 Brazilian National Health Survey. The average consumption days a week of core (8‐item) and non‐core (4‐item) foods were the outcomes, measured using a Food Frequency Questionnaire. Tooth loss severity was the main exposure, using a four‐category ordinal variable: mild (1‐12 teeth missing), moderate (13‐22), severe (23‐31) and edentulous (all 32). Sociodemographic, tobacco smoking, use of dental prosthesis, difficulty in chewing and systemic conditions were among the covariates. Linear regression models estimated the association between tooth loss and food consumption. Results Almost two‐thirds of participants had moderate or worse levels of tooth loss. Older adults with more severe tooth loss reported an overall lower consumption of core and higher non‐core foods than those with mild tooth loss. Worse tooth loss severity was associated with lower consumption of vegetables and/or legumes and fruits, and higher consumption of beans, artificial fruit juices and confectionery. Conclusions Older Brazilian adults with more severe tooth loss are consuming lower core and higher non‐core foods. Our findings reinforce the importance of the common risk factor approach to tackle the adverse effects of tooth loss on diet.
