The purpose of this study was to test whether moderate alcohol consumption has any positive effect on lowering blood pressure among Koreans. Study subjects were Korean adults 20 years or older (n=5,234) who participated in the 2001 Korean National Health and Nutrition Examination Survey (KNHANES). Analysis of variance and analysis of covariance were used to construct univariate and multivariate models relating alcohol consumption to blood pressure for the analysis. After adjustment for possible covariates, drinkers (regardless of drinking level) had significantly higher systolic and diastolic blood pressure, compared with never-drinker for male subjects. Diastolic and systolic blood pressures were also significantly elevated with the drinking frequency and amount of alcohol intake among male subjects. For the female subjects, only diastolic blood pressure was significantly associated with the alcohol consumption at multivariate model. however, low level alcohol consumption did not show any sign of lowing effects on blood pressure. The result implies that moderate alcohol consumption did not have any positive effect on lowering blood pressure among Koreans for either sex.

Objectives: This study compared the nutritional status of child-bearing age women between the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea). Methods: The data presented in the DPRK Final Report of the National Nutrition Survey 2012 was utilized for the nutritional status and food intake of North Korean women. To produce the South Korean women's data comparable to those of North Korean women, the data from the 2012 National Health and Nutrition Survey were analyzed and the data presented in the 2010 Report of the Korean Agency for Technology and Standards were utilized. Results: The prevalence of maternal anemia (blood hemoglobin < 12.0 g/dL) was over 30% in all the age groups of North Korean women and 8.9%, 14.2%, 16.4% in 20-29, 30-39, 40-49 year old South Korean women, respectively. The prevalence of maternal protein-energy malnutrition (Mid-Upper Arm Circumference < 22.5 cm) was 25.2%, 21.4%, 21.8% in 20-29, 30-39, 40-49 year old North Korean women, respectively and less than 10% in all the age groups of South Korean women. Result of dietary diversity comparison showed that North Korean women consumed less food than South Korean women at all food groups: grains, fruits, vegetables, meat, and dairy. Percentage of North Korean women having consumed protein rich foods-meat and fish, eggs or dairy products-were much lower than those of South Korean women. Conclusions: The striking disparity of nutritional status between South and North Korean women indicates that nutrition support for North Korean women is essential in the process of preparation for a unified nation.

This study was performed to identify nutritional status and eating behaviors of underweight male adolescents aged 15 to 19 years. The subjects selected by using the data of KNHANS-2001 were 32 underweight boys and 135 normalweight ones. We found that weight, waist and hip circumference of the underweight group were significantly different to normal-wight group, but height and waist-hip ratio were not. Their serum indices belonged within normal ranges and showed no difference between the two groups. Their energy and nutrient intakes were mostly poor. The level and proportion of the subjects below EAR, NAR and INQ of each nutrient were not significantly different between the two groups. There were no difference of frequencies of skipping meals, snacking and eating-out between the two groups, either. When comparing frequencies of food intakes, the underweight group consumed significantly more of fermented fishes and less milk than the normal-weight group. And the former had significantly more rest/sleep, no-does and supplementation and less regular excercise than the latter. The underweight group perceived more correct self-images than the normal-weight group and they tried more to increase their body weight during weight control practice (p<0.001). It was concluded that the underweight group showed no different biochemical indices, nutrient intakes, and dietary behaviors to the normal-weight group, but they revealed significantly higher non-active activities like rest and supplementations.

Dyslipidemia is a major risk factor for cardio-cerebrovascular disease. Although the prevalence among Korean adults is very high, its management is known to be poor. The aim of this study was to access the prevalence, awareness, treatment, and control rates of dyslipidemia according to treatment guideline rather than diagnostic criteria. The risk factors for cardio-cerebrovascular disease were evaluated to apply the appropriate risk-based threshold of the lipid treatment targets according to risk category. Analysis was done using nationally representative data (n = 16,263) collected from adults aged 20 years and older participating the Korea National Health and Nutrition Examination Survey (KNHANS) 2010-2012. The age-standardized prevalence rate of dyslipidemia according to treatment criteria was 34.1%. Of these prevalent cases, however, only 19.2% were aware; 9.5% treated; and 8.7% controlled. The age-standardized control rate among treated persons was 47.5%. Men had a significantly higher prevalence than women (39.7% vs. 28.8%), but a significantly lower rate of awareness, treatment, and control (16.0% vs. 22.3%, 7.7% vs. 11.3%, and 6.1% vs. 11.2%, respectively). As the higher risk category, the prevalence rate was higher but the control rate was lower. The prevalence of patients with diabetes was 82.5% when applying the treatment criteria (LDL-cholesterol level of ${\geq}100mg/dL$ and triglyceride level of ${\geq}200mg/dL$). However, only 11.9 % of these were controlled, whose LDL-cholesterol and triglycerides were lower than the treatment goals. Our findings suggest that effective strategies are required to decrease the gap between the prevalence of dyslipidemia and the following treatment. It would be worthwhile to strengthen the follow-up management of patients with dyslipidemia in the National Health Screening Program, especially in the high risk group of cardio-cerebrovascular disease.
