Abstract Aim Impairment of masticatory function in elderly patients with terminal dentition due to stage IV periodontitis (TDS4P) may lead to lower nutritional intake. The study aimed to report the dietary intake and nutrition status of elderly patients with TDS4P and compare them with those of the elderly Chinese population and the Chinese Dietary Reference Intakes (DRIs). Materials and Methods Fifty‐one consecutive subjects (≥55 years old) with TDS4P were enrolled. Average dietary intake was evaluated based on a 3‐day 24‐h dietary recall (24HR) and food frequency questionnaire (FFQ). The daily intake of fresh vegetables and fruits, dietary energy as well as macro and micronutrients were calculated and compared with matched national data and the Chinese DRIs. Nutritional status was assessed by Short‐Form Mini‐Nutritional assessment. Results Of the subjects, 19.6% (95% CI: 7.2%–28.1%) were at risk of malnutrition. The mean daily energy intake was 1517.4 kcal (95% CI: 1400.5–1634.3) for males and 1110.7 kcal (95% CI: 1001.5–1219.9) for females, which were very low compared with both the national data and the DRIs. Females derived a higher percentage of energy from fat. The mean daily intake of vegetables was 151.4 g (95% CI: 128.1–174.8) by FFQ and 130.9 g (95% CI: 104.6–157.3) by 24HR. Both results were significantly lower than the national reports (95% CI: 310.3–340.1) and the DRIs (300–450 g). Insufficient micronutrient intake, especially vitamins A, C and E, was also found. Conclusions Elderly subjects with TDS4P had a lower daily energy intake, vegetable and fruit consumption and essential macro and micronutrient intake. More studies are needed to clarify the impact of periodontitis and tooth loss/replacement on nutrition and healthy ageing.
