The effect of aging and dental status on the frequency of eating out

Association between Number of Teeth and Eating out of Home: A 2019 Statistical Survey of the Japanese Representative Population

Eating out of home (EOH), with its diverse food options, can benefit those with difficulty preparing their meals, especially older adults. Oral health status may be a determinant of EOH, as food accessibility is influenced by oral health, but this association remains unclear. This cross-sectional study used merged data from two national statistical surveys conducted in 2019. Participants were individuals aged ≥ 65 years who responded to both surveys.

Breaking the vicious circle of diet, malnutrition and oral health for the independent elderly

Aging impairs senses, mastication, oral status and function, causing nutritional needs and diet insufficiencies. The present needs of independent older adults suggest that health research and oral health care should shift from reductionist disease management to integral and personal treatment plans, including lifestyle, psychological, nutritional and oral health coaching approaches. Dentists and other medical professionals that work in the field of gerodontology should be educated on the macro and micronutrient needs of the elderly and incorporate certain nutritional plans early in the life of their patients with their approval and cooperation, in order to postpone tooth loss and masticatory impairment. Old recipes such as the Mediterranean diet should be kept as a base for all the elderly and be enriched in a customized interpersonal way from the dentist as well as the medical professional according to the specific needs of one's oral and general health status. In this nonsystematic review paper, the basic aspects of the vicious cycle of nutrition and oral health status are discussed and suggestions of major nutrients' influence and needs for independent elders are reported. Based on the scientific data collected, suggestions are made for the food industry for better quality and dosage of foods for this category of individuals. Such strategies can be a whole new area of interest for the food industry in order to obtain better quality of food packaging for the independent OA with accepted texture, odor, colors, macronutrients and micronutrients' consistency and in specific portions.

The Eating Experience: Adaptive and Maladaptive Strategies of Older Adults with Tooth Loss

OBJECTIVE

To explore the eating experience and eating-related quality of life (ERQOL) of community-dwelling older adults with tooth loss.

METHOD

Nineteen older adults from the clinics of a northeast US dental school who met inclusion criteria (>65 y old, <20 teeth, and no dentures) composed the sample. For this mixed methods study, demographic characteristics, number and location of teeth, Mini Nutritional Assessment-Short Form score, and anthropometrics data were collected; semistructured interviews were conducted to collect in-depth information about the eating experience and ERQOL. Thematic analysis was completed with NVivo 12 software (QSR International).

RESULTS

Participants' mean age was 71.3 y (SD = 5.2); 52.6% (n = 10) were women; 63.2% (n = 12) were Black or African American. The mean Mini Nutritional Assessment-Short Form score of 12.1 was reflective of normal nutrition status; 31.6% (n = 6) of patients were at risk for malnutrition or were malnourished. Fifteen percent (n = 3) were fully edentulous; 84.2% (n = 16) had 1 to 19 teeth (mean = 10.8, SD = 6.5). The 2 overarching themes identified were adaptive and maladaptive behavioral responses to tooth loss. Adaptive strategies included modification in food preparation and cooking methods, food texture selection, meal timing, and approaches to chewing. Maladaptive behaviors included food avoidance and limiting eating and smiling in front of others. Psychosocial factors, including finances, limited food choices and ERQOL, whereas the support of family and friends enhanced ERQOL according to participants.

CONCLUSION

Older adults with tooth loss exhibit both adaptive and maladaptive behaviors that affect their eating experience, dietary intake, and ERQOL. While many expressed positive adaptive coping strategies, they also described maladaptive behaviors, including avoidance of healthy foods and limiting eating during social interactions, which may affect their nutritional status and overall health and well-being. Further research is needed to explore how duration and severity of tooth loss influence these behaviors and risk of malnutrition. Interprofessional approaches are needed to support positive adaptation and coping with tooth loss.

KNOWLEDGE TRANSFER STATEMENT

The results of this study can be used by health professionals treating patients with tooth loss in an effort to improve their eating experience and eating-related quality of life. The findings provide data to support further studies and the need for evidence-based guidelines and educational materials to meet the unique needs of older adults with tooth loss.

The Association of Poor Oral Health Parameters with Malnutrition in Older Adults: A Review Considering the Potential Implications for Cognitive Impairment

Poor dental status and chewing deficiencies have been associated with cognitive decline. Altered dietary habits and malnutrition have been suggested as linking mechanisms. The aim of the present review was thus to investigate if poor oral health, and in particular tooth loss and impaired masticatory function, may affect dietary selection and nutritional intake in older adults, and moreover, to assess if prosthodontic dental care may improve nutritional status. Extensive tooth loss may impair masticatory function. Several studies in older populations have shown that severe tooth loss and masticatory impairment are associated with limited consumption of various food types (especially fruits and vegetables), increased consumption of sugary and easy-to-chew foods, and lower dietary intake of fibre and vitamins. However, these findings are not consistently reported, due to methodological variation among studies, potential adverse causalities, and the multifactorial nature of food choices. On the other hand, a few interventional studies revealed that prosthetic rehabilitation of missing teeth, when accompanied by dietary counselling, may improve dietary habits and nutritional intake. Further research is required to improve current knowledge of these associations. Under the limitations of the current study, a functional dental arch of natural or artificial teeth is important for maintaining adequate chewing efficiency and ability, but this only partly contributes to food choices and nutritional status. The multifactorial nature of food choices necessitates the interprofessional collaboration of dental professionals, dietetics practitioners, and primary care providers to improve dietary habits and nutritional intake.

Environmental Strategies to Promote Food Intake in Older Adults: A Narrative Review

Aging is often accompanied by lower intakes of food energy and consequent negative effects on health. To some extent this is due to declines in physiological ability, including the sensory responsiveness to regulate food intake. Fortunately, environmental factors may still influence food intake in older adults. Factors such as social facilitation, modeling, and nutrition knowledge and skills have been shown to stimulate their food intake. While environmental factors such as the eating location, portion size, food presentation, and labeling are known to influence eating behavior, their effectiveness in stimulating food intake in older persons is not well delineated. It is suggested that improving the environmental stimuli that promote food intake is a viable strategy to overcome age-related declines in nutrient intakes. This strategy is so promising that further research is warranted.
