Obese adults showed significantly reduced masticatory function compared to normal-weight individuals. This study suggests obesity may negatively impact chewing ability in non-elderly populations.
Area of Science:
- Nutrition and Dietetics
- Oral Health
- Human Physiology
Background:
- Obesity is linked to abnormal eating behaviors that may affect masticatory function.
- Limited research exists on masticatory function in obese individuals.
Purpose of the Study:
- To investigate masticatory function in non-elderly obese Japanese adults.
- To explore the relationship between obesity and masticatory function.
Main Methods:
- A chewing gum mixing method was used to assess masticatory function.
- Oral health status (teeth count, decay, missing, filled) was also evaluated.
- Study included 75 obese and 98 normal-weight adults aged 25-40.
Main Results:
- Obese subjects exhibited significantly lower masticatory function than controls.
- No significant differences in the number of teeth were observed between groups.
- Multiple regression confirmed a correlation between obesity and reduced masticatory function.
Conclusions:
- Non-elderly obese adults demonstrate impaired masticatory function.
- Obesity is a potential contributing factor to reduced chewing efficiency.
