Comparison of Nutrient Intake and Diet Quality Between Hyperuricemia Subjects and Controls in Korea

Hyperuricemia is associated with metabolic syndrome as well as gout, and the prevalence of hyperuricemia is increasing in Korea. This study aimed to compare the nutrient intake and diet quality between hyperuricemia subjects and controls. Of the 28,589 people who participated in a health examination between 2008 and 2011, 9,010 subjects were selected whose 3-day food records were available. Clinical and laboratory data were collected from electronic medical records. Diet quality was evaluated using the food habit score (FHS), nutrient adequacy ratio (NAR), and mean adequacy ratio (MAR). The prevalence of hyperuricemia was 13.8% (27.1%, men; 5.2%, women). Body mass index, waist circumference, triglycerides, total cholesterol, and low-density lipoprotein cholesterol were significantly higher (p < 0.0001), while high-density cholesterol (p < 0.001) was significantly lower in the hyperuricemia subjects than in the controls. The hyperuricemia subjects had a lower intake of vitamin A (p < 0.004), vitamin C, folate, fiber, and calcium than the controls (p < 0.0001). Intake of vegetables and dairy products was significantly lower, whereas alcohol intake was significantly higher in the hyperuricemia subjects than in the controls ( p < 0.0001). The FHS (p < 0.0001), MAR (p < 0.0001), and NARs for vitamin A (p = 0.01), vitamin B2, vitamin C, folate, and calcium (p < 0.0001) were significantly lower in the hyperuricemia subjects than in the controls. In conclusion, the hyperuricemia subjects reported poorer diet quality than the controls, including higher alcohol intake and lower vegetable and dairy product intake.

Evaluation of the Dietary Diversity and Nutrient Intakes in Obese Adults / 대한지역사회영양학회지

The purpose of this study was to assess the diet diversity, food habit and nutrient intake of obese adults who were visiting the health promotion center. This study was accomplished with the 138 obese adults (men = 103, women = 35) aged over 20 years old whose BMI were above 25 kg/m2. Nutrient adequacy ratio (NAR), the number of foods (Dietary Variety Score, DVS), and food group consumed (Dietary Diversity Score, DDS) by using the data from the three days record were analyzed and the food habit and lifestyle were assessed by self reporting questionnaire. The average energy intake of men was 2150.2 kcal which was significantly higher than that of women (p < 0.05). The intake ratio of carbohydrate, protein and fat over total energy was 54.8% : 19.3% : 25.8% in men, 59.5% : 17.8% : 22.6% in women, respectively. Frequency of the breakfast in a week above 4, 2~3 time and under one time was 75.7%, 10.7% and 9.7% in men, 77.1%, 5.7% and 14.3% in women respectively. Frequency of eating between meals in a day under one time was 73.8% in men, 57.1% in women (p < 0.05). The average DDS and DVS was 3.63 +/-0.07 and 14.10 +/-3.45, respectively which was significantly correlated with MAR (r = 0.40 in DDS, r = 0.64 in DVS, p < 0.01). The most frequent style of food pattern was DMGFV = 01101 in 35% of men, and DMGFV = 01111 in 37.1% of women. Our results show that dietary diversity and variety are useful parameters for evaluating nutrient intakes in obese adults. These findings suggest that nutritional education based on obese persons' eating behavior and eating diversity may be required to increase educational efficiency of weight control programs.
