우리나라 성인의 식이섭취상태와 식사 질 평가 및 뇌졸중 유병률과의 관계 연구

Abstract

This study was performed to evaluate the comparison between dietary intake and quality according to stroke prevalence and to determine the association between dietary factors and stroke prevalence using the 5th (2010-2012) Korean National Health and Nutrition Examination Survey (KNHANES) data. The subjects of this study included 6,131 Korean over 50 years old who participated in 5th KNHANES excluding missing data. Health-questionnaires, examination and nutrition survey were conducted by face-to-face interview and measurement. Then, collected data were analyzed for Nutrient Intake (NI), Index of Nutritional Quality (INQ), Nutrient Adequacy Ratio (NAR), Mean Adequacy Ratio (MAR), dietary patterns (DMGFV), Dietary Diversity Score (DDS) and Dietary Variety Score (DVS). All statistical analysis were performed using the SAS (Version 9.3, SAS Institue, Cary, NC). Storke prevalence rate has been showed 3.5% in over 50 years old Korean and male (4.2%) was higher than female (2.9%,p=0.05). According to demographic characteristic, stroke prevalence was higher in high age(p<0.001), less-educated level and low household income group(p<0.05). It was higher in group having medical history of hypertension, diabetes and family history of stroke as well(p<0.001). The anthropometric and biochemical results, female prevalence group showed slightly higher in waist(p=0.003) and body mass index(p=0.04) than normal group. Male and female prevalence group showed high glucose and HbA1c level than normal group(p<0.05). It was observed that stroke prevalence rate showed a relatively higher in case which did not take any dietary supplements(p=0.021) and does not recognize a nutritional label(p<0.001). As a result of nutritional intake, among male prevalence population, it has been showed slightly lower nutritional intake than normal population(p<0.05). In case of female prevalence population, it has been showed lower intake of energy(p=0.004), vitamin C(p=0.037), riboflavin(p=0.008), niacin(p=0.047) than normal group. In INQ results, male prevalence group was lower in intake of protein(p=0.009), vitamin A(p=0.023), riboflavin(p=0.022), calcium(p=0.008) than normal group and female prevalence group was lower in intake of vitamin C(p=0.044) than normal group. Futhermore, in NAR results, male prevalence group was lower in intake of all nutrient than normal group(p<0.05) and female prevalence group was lower in intake of vitamin C(p=0.037), riboflavin(p=0.008), niacin(p=0.047) than normal group. For those reason, MAR was lower in male and female prevalence group than normal group(p<0.05). In dietary patterns, stroke prevalence group has been showed intake deficit of meat, fruit and milk products. Male and female prevalence group was lower in DDS(p<0.01) and DVS(p<0.05) than normal group. In conclusion, stroke prevalence group was lower in nutrient intake and dietary quality than normal group. In addition, logistic analysis suggest that MAR is most relevant dietary factors in stroke prevalence. Stroke is the second leading cause of death in Korea, stroke risk factors has been increasing. According to this study, stroke prevalence was influenced by nutrient intake and dietary quality, therefore dietary and nutritional management is required. Also, individual nutrition education is required for stroke prevention and management.
