Assessment & Research

Oral health and nutritional status of semi-institutionalized persons with mental retardation in Brazil.

Batista et al. (2009) · Research in developmental disabilities 2009
★ The Verdict

In Brazilians with ID, bad teeth and extra pounds travel together—check both in the same intake visit.

✓ Read this if BCBAs doing intake in day programs or group homes.
✗ Skip if Clinicians who only run verbal behavior sessions and never touch health screening.

01Research in Context

01

What this study did

Vieira and colleagues visited two care homes in Brazil. They looked at the teeth and weighed 200 people with intellectual disability.

The team used dentist mirrors and bathroom scales. They also asked what each person usually ate.

02

What they found

Most people had bad teeth. Many kids were already overweight.

The heavier the child, the worse the tooth decay tended to be.

03

How this fits with other research

Klein et al. (2024) saw the same diet trouble in younger Brazilian kids with Down syndrome. Over half had been weaned too early and were eating sweets by age two.

Leiva-García et al. (2019) found the same mouth-body link in children with autism. Picky eaters had more crooked teeth and bleeding gums.

Heald et al. (2020) looked at dental records in the United Kingdom. Adults with ID visit the dentist often, but dentists pull teeth instead of fixing them. The two facts seem opposite, yet both are true: people go, but care is still poor.

Hove (2007) adds another piece. In Norway, six out of ten adults with ID bolt food, refuse meals, or eat too fast. These behaviors can hurt both weight and teeth.

04

Why it matters

Check both weight and teeth at intake. Ask about sweets, mealtime speed, and who helps with brushing. A five-minute diet-and-dental screen can flag the kids who need a dentist and a nutritionist before behavior plans start.

03Original abstract

Association between oral health status and nutritional status was investigated in 200 semi-institutionalized persons with mental retardation aged 5-53 years, 45.5% female, in the cities of Florianópolis and São José, province of Santa Catarina, Brazil. In this cross-sectional study, clinical-odontological examination revealed a high percentage of individuals (68%) with heavily compromised dentition. The index of decayed, missing and filled deciduous and permanent teeth, which increased from 2.85+/-2.87 in children to 20.5+/-6.86 units in adults, was used to classify the individuals' oral health status. Anthropometric evaluation revealed the prevalence of suboptimal nutritional status in 52% of children and adolescents [22% underweight, 30% at risk of overweight or overweight], and in 60% of adults [7% underweight, 53% overweight or obese]. Significant association was found between unsatisfactory oral health status and overweight in children (chi(2)=4.627; p=0.031). Findings evidenced the existence of a relationship between oral health status and nutritional status in persons with mental retardation.
