Dietary patterns (DP) reflect chronic dietary exposure and thus are an optimal technique for examining diet and disease relationships. This study examined the DP of participants in the Geisinger Rural Aging Study (114 male, 158 female mean age 78). Anthropometric data and a fasting blood sample were collected at a clinic visit. Dietary data was collected using 4, 24‐hour recalls; average servings from 24 subgroups were analyzed via cluster analysis. Four DP were generated: Sweets and fat (n=91); Low calorie (n=85); Meats and refined grains (n=34), and prudent (n=63). The sweets and fat DP had highest intakes of whole fat dairy, added sugars and sweets, and dairy desserts. The meats and refined grain DP had the most adverse biomarker profiles, waist circumference and dietary fats when compared to all other DP. The low calorie DP was comprised of low intakes of all food groups, with the lowest energy intakes. The prudent DP had high intakes of fruits, vegetables, lean proteins, and whole grains and the highest mean nutrient adequacy ratio. Both the low calorie and prudent DP exhibited higher serum B12 than the less desirable patterns. This work supports the utility of DP assessment, and relates DP to meaningful clinical outcomes that may help determine individuals at risk.
