Evidence for the effects of different health behaviors, including diet, in elderly diabetes is currently limited. The aim of this study was to compare the quality of diet and health behaviors in Korean elderly T2DM patients, using a glycemic control. T2DM elders(>65 yr, n=48) were recruited and categorized by the concentration of glycated-hemoglobin HbA1c; subjects with HbA1c<7% were the good control(GC) group, and subjects with HbA1c≥8% constituted the poor control(PC) group. General characteristics, self-management behavior questionnaires, and 3-d diet records were all collected and assessed. No significant differences in general characteristics between GC and PC were detected, with the exception of a higher level of education in GC(p<0.05). A twofold longer duration of diabetes was observed in PC as compared to GC(p<0.01). The GC group did exercise for a longer time(p<0.001), and had an earlier beginning of diabetes self-management education (DSME) by healthcare practitioners using a team teach as compared with the PC group(p<0.05). The total dietary quality index(p<0.001) and individual index for carbohydrate(p<0.001) or vegetables and fruit(p<0.05) were better in GC than in PC. Therefore, the earlier DSME including intensive exercise and balanced diet selection should be expected to improve glycemic control in diabetic Korean elders.

뇌경색을 동반질환으로 가지는 당뇨병 환자와 뇌경색이 발병하지 않은 당뇨병 환자의 식·생활습관, 영양소 섭취상태 및 식사의 질을 비교한 결과를 요약하면 다음과 같다. 1) 뇌경색 당뇨병 환자인 DM-CI군과 비뇌경색 당뇨 환자인 DM군의 평균 연령은 65.6, 69.2세, 당뇨병 유병 기간은 10.9, 9.7년으로 두 군 간의 차이가 없었다. 당뇨병교육을 받은 경험은 DM-CI군에서 유의적으로 낮았으며(DM-CI: 21.4% vs. DM: 47.5%) 약물치료에서도 두 군간에 유의적인 차이가 관찰되었다 (p < 0.05). 흡연율 (DMCI: 25.0% vs. DM: 2.5%)과 음주율 (DM-CI: 28.6% vs. DM: 10.0%)은 DM-CI군에서 유의적으로 높았으나 (p < 0.05) 규칙적인 운동과 운동 횟수에서는 DM-CI군에서 유의적으로 낮았다 (p < 0.05). 2) 신체계측에서는 군 간에 차이가 관찰되지 않았으나 여자의 경우, 평균 신장이 DM-CI군에서 유의적으로 높았으며 (p < 0.05) 체질량 지수가 두 군 모두 과체중-비만 범위에 있었다. 혈압측정 결과, 수축기 혈압은 군 간의 차이를 보이지 않았으나 이완기 혈압에서 남녀 모두 DM-CI군에서 유의적으로 높았다 (p < 0.05). 3) 식사를 규칙적으로 하고 있는 경우는 DM군에서 유의적으로 높았고 하루에 한 끼를 거르는 경우는 DM-CI군에서 많았다 (p < 0.05). 식사시간이 불규칙한 경우는 DMCI군에서 유의적으로 높았으며 (p < 0.05) 간식의 섭취빈도 및 외식의 섭취 빈도에서는 두 군 간에 차이가 없었다. 4) 일일 탄수화물, 나트륨 섭취량은 남녀 모두 DM-CI군에서 유의적으로 높았으며, 지방과 콜레스테롤은 여자 DMCI군에서 유의적으로 높았다 (p < 0.05). 비타민 B₁, B₂, C, 엽산, 칼슘 섭취는 DM군에서 높았으며 단백질, 아연의 섭취는 DM-CI군에서 유의적으로 높았다 (p < 0.05). 영양소섭취량을 권장섭취량과 비교한 결과, DM군에서 비타민 A, 칼슘, 아연이 권장섭취량에 미달되었으며 DM-CI군에서는 비타민 B₁, 비타민 B₂, 나이아신, 엽산, 비타민 C, 칼슘이 미달되었다. 5) 식사의 적절성을 평가하는 INQ의 경우, DM-CI군에서 비타민 B₁, 비타민 C, 비타민 B₂, 엽산, 칼슘의 적정도가 유의적으로 낮았다 (p < 0.05). 식품군의 다양성을 평가하는 DDS는 DM-CI군에서 유의적으로 낮았으나 (p < 0.05) 섭취 식품의 다양성을 평가하는 DVS는 두 군 간에 차이가 없었다. 식사 섭취패턴은 두 군에서 유의적으로 다르게 나타났는데 DM군에서는 다섯 가지 식품군을 섭취하는 비율이(GMVDF = 11111) 가장 높았던 반면 DM-CI군에서는 유제품군을 섭취하지 않는 경우가 (GMVDF = 11101) 가장 높았다 (p < 0.05). 식사의 질 평가에서 DM-CI군, DM군이 각각 8.3 ± 1.3, 6.9 ± 1.7로 DM-CI군에서 식사의 질이 유의적으로 낮았다 (p < 0.05). 결론적으로, 뇌경색을 동반한 당뇨병 환자는 뇌경색을 동반하지 않은 당뇨병 환자에 비해 흡연, 음주, 운동 등의 건강관련 습관이 좋지 않았다. 또한 열량, 지방, 나트륨, 콜레스테롤의 섭취는 많은 반면, 비타민과 무기질의 섭취량이 낮았으며 영양소 섭취 적정도와 식품 섭취패턴 및 식사의 질이 저하되어 있었다. 따라서 뇌경색을 동반한 당뇨병 환자는 당뇨병 관리를 위한 건강 관련 습관을 조절함과 동시에 다양한 식품 섭취를 통하여 식사의 질을 높이는 것이 요구된다. 당뇨병은 기본적으로 식사요법을 잘 실행할 때 여러 합병증의 발병을 예방할 수 있으며 약물 복용 시에도 그 중요성은 강조된다. 식사요법은 올바른 영양교육을 통하여 건강관련 생활습관과 함께 습득될 수 있는 부분이므로 당뇨병 환자뿐만 아니라 합병증을 동반한 당뇨병 환자에서도 개개인에 맞는 적극적인 의학영양치료가 필요할 것으로 사료된다. Diabetes mellitus (DM) is a well-established independent risk factor for cerebral infarction (CI). Additionally, the DM as well as CI are influenced significantly by health-related behaviors and diets. The aim of this study was to compare the food habits, nutrient intakes, and dietary patterns and quality in DM patients with CI (DM-CI) and without CI. This study was accomplished with 68 subjects (DM-CI group = 28, DM group = 40). Health-related behaviors, food habits, nutrient intakes and dietary quality were investigated. As a result, the mean ages and durations of diabetes in DM-CI and DM groups were 65.6 ± 9.2, 10.9 ± 8.5 and 69.2 ± 3.0, 9.7 ± 8.4 years, respectively. The health-related behaviors such as, smoking, alcohol drinking, and regular exercising in both groups were significantly different (p < 0.05) showing the number of subjects who were smoking and drinking alcohol was significantly higher in DM-CI group and the opposit result was seen for exercise. In male subjects, the intake of carbohydrate and sodium of DM-CI group were significantly higher than those of DM group (p < 0.05). In female subjects, the intake of calorie, carbohydrate, fat, sodium, and cholesterol were significantly higher in the DM-CI group (p < 0.05). Daily intake of vitamin B1, vitamin B2, folate, vitamin C, and calcium were significantly higher in DM group (p < 0.05). In the comparison with the dietary reference intake for Koreans (KDRI), vitamin B1, vitamin B2, folate, and calcium intakes were lower in DM-CI group whereas calcium and zinc intakes were in DM group. Moreover, index of nutritional quality (INQ) of vitamin B1, vitamin B2, vitamin C, folate, and calcium were lower significantly in DM-CI group (p < 0.05). Dietary quality including dietary diversity score (DDS), GMVDF (grain, meat, vegetable, dairy, fruit), and dietary quality index (DQI) was significantly lower in DM-CI group (p < 0.05). According to the results, diabetic mellitus patients accompanied by cerebral infarction had poorer eating patterns and dietary quality in accordance with poorer health-related behaviors compared with the DM patients without CI.

Assessment regarding the nutritional status of Parkinson's disease (PD) patients is important because their nutritional status influences the outcome of disease. The purpose of this study investigated the dietary habits, dietary quality, and quality of life for Korean PD patients according to their nutritional status. Seventy PD patients were recruited from K University Hospital (KMC IRB#0918-07) from February 2010 to October 2011. To diagnose PD, the United Kingdom Parkinson's Society Brain Bank standards were used by a neurology physician. The participants were interviewed and assessed using various tools, including a general questionnaire, anthropometrics, questionnaires for dietary habits, dietary diversity score (DVS), dietary variety score (DVS), diet quality index-international (DQI-I), beck depression inventory (BDI), the Korean version of mini mental state examination (K-MMSE), and 36-item short-form health survey (SF-36). The results of the study were as follows: 1) Most of the PD patients (69.0%) were at risk of malnutrition, and 8.5% and 22.5% of the subjects were malnourished and well-nourished, respectively. 2) Clinical symptoms (swallowing and chewing difficulties) were obvious, and the quality of diet (DDS, DVS, DQI-I) was low in the malnourished group (p < 0.01). 3) The malnourished group had significantly lower scores regarding SF-36 (quality of life) as well as that of cognitive function (p < 0.05). 4) The nutritional status of PD patients was significantly correlated with their depression (p < 0.05) and quality of life (p < 0.01). These results indicate that appropriate nutritional management will improve the nutritional status and quality of life as well as the cognitive function in Parkinson's disease patients.

A food exchange system for diabetes is a useful tool for meal planning and nutritional education. The first edition of the Korean food exchange lists was developed in 1988 and the second edition was revised in 1995. With recent changes in the food marketplace and eating patterns of Koreans, the third edition of food exchange lists was revised in 2010 by the Korean Diabetes Association, the Korean Nutrition Society, the Korean Society of Community Nutrition, the Korean Dietetic Association and the Korean Association of Diabetes Dietetic Educators through a joint research effort. The third edition is based on nutritional recommendations for people with diabetes and focuses on adding foods to implement personalized nutrition therapy considering individual preferences in diverse dietary environment. Foods were selected based on scientific evidence including the 2007 Korea National Health and Nutrition Examination Survey data analysis and survey responses from 53 diabetes dietetic educators. While a few foods were deleted, a number of foods were added, with 313 food items in food group lists and 339 food items in the appendix. Consistent with previous editions, the third edition of the food exchange lists included six food categories (grains, meat, vegetables, fats and oils, milk, and fruits). The milk group was subdivided into whole milk group and low fat milk. The standard nutrient content in one exchange from each food group was almost the same as the previous edition. Korea Food & Drug Administration's FANTASY (Food And Nutrient daTA SYstem) database was used to obtain nutrient values for each individual food and to determine the serving size most appropriate for matching reference nutrients values by each food group. The revised food exchange lists were subjected to a public hearing by experts. The third edition of the food exchange lists will be a helpful tool for educating people with diabetes to select the kinds and amounts of foods for glycemic control, which will eventually lead to preventing complications while maintaining the pleasure of eating.
