Sequential relationships of food intake in nursing home residents with dementia: Behavioural analyses of videotaped mealtime observations.

The videos showed only parts of meals and one-on-one interactions, so the findings may not apply to group mealtimes or more complex staff-resident interactions. All residents had moderately severe or severe dementia and similar background, so the study says little about mild dementia, other diagnoses, or diverse populations. The study found temporal associations, not causal effects, and the parent intervention was staff communication training, not mealtime-specific feeding strategies. Dysphagia diagnosis, special diets, taste, and detailed food texture were not collected, so swallowing-related reasons for no intake could not be examined. Dementia stage had little variation, so its role could not be assessed well.

Do not read the odds ratios as proof that staff can increase intake by changing behaviour. These are temporal associations in coded videos, and the study did not test mealtime strategies or show causality.
