Dentition, nutritional status and adequacy of dietary intake among older residents in assisted living facilities.

Objective: We examined the relationships between dentition, nutritional status and dietary intakes of energy, protein and micronutrients among older people in assisted living facilities in Helsinki.

Background: Poor dentition is associated with malnutrition. Less is known about how dentition is associated with detailed nutrient intakes in institutionalised older people.

Materials And Methods: This cross-sectional study assessed 343 participants (mean age 83 years). Dentition was assessed by trained ward nurses and divided into edentulous participants without dentures (group 1), edentulous participants with removable dentures (group 2) and those with any natural teeth (group 3). Nutritional status was assessed by Mini Nutritional Assessment (MNA). The energy, protein and nutrient intakes were calculated from detailed 1-day food diaries and compared with the recommendations of the Finnish National Nutrition Council as a measure of dietary adequacy. Assessment included also participants' cognitive and functional status.

Results: Of the participants, 8.2, 39.1 and 52.8% were in groups 1, 2 and 3, respectively. Altogether 22% were malnourished according to MNA. Group 1 had the poorest nutritional status. A large proportion of participants consumed less than the recommended amounts of energy, protein or micronutrients. Half of the participants consumed <60 g/day of protein. The intake of protein was significantly lower in group 1 than in other two groups.

Conclusion: Malnutrition and inadequate protein intake were very common and associated with dentition among older people with multiple disabilities in assisted living facilities. Assessment of dental status should be part of good nutritional care in long-term care.
