OBJECTIVE
Prevention of frail skin is important in older people because frail skin is associated with a risk of injury in this population. In this study, we investigated the association of nutritional status and habitual dietary intake with skin conditions in community-dwelling older people.

DESIGN
Cross-sectional study.

SETTING
Three community settings in Japan from autumn to winter.

PARTICIPANTS
Older people aged ≥65 years without care-need certification (n=118).

MEASUREMENTS
Malnutrition and obesity were evaluated to assess the nutritional status. Nutrient and food group intakes per 1000 kcal were evaluated using a brief self-administered diet history questionnaire. Dietary patterns based on food groups were evaluated by principal component analysis. Skin condition parameters, including stratum corneum hydration, appearance of xerosis (specific symptom sum score [SRRC score]), and dermal intensity by high-frequency ultrasonography, were measured on a lower leg. Multiple linear regression analysis was performed with adjustment for confounders.

RESULTS
The mean (standard deviation) age was 74.1 (4.8) years, and 83.1% of participants were female. A higher intake of plant fat (p=0.018) was associated with a lower SRRC score. Higher intakes of α-tocopherol (p=0.050) and vitamin C (p=0.017) were associated with increased dermal intensity. A body mass index ≥25 (p=0.016) was associated with decreased dermal intensity. A dietary pattern characterized by higher vegetable and fruit intake was associated with a better skin condition.

CONCLUSION
Plant fat, antioxidant vitamins, and a dietary pattern characterized by vegetables and fruits showed positive and obesity showed negative associations for frail skin in community-dwelling older people.
