Purpose: This study aimed to examine the compliance to a low-salt diet, sodium intake, and preferred salty taste in elderly patients with hypertension. Methods: A cross-sectional descriptive design was used. Participants were 105 elderly patients with hypertension living in a rural area. The compliance with a low-salt diet, sodium intake, and preferred salty taste, blood pressure, body mass index, and waist circumference were measured, and compared according to the general characteristics and the levels of blood pressure. Descriptive statistics, $X^2$-test, t-test, and ANOVA were used for data analysis. Results: compliance with a low-salt diet was marginally elevated. Sodium intake was relatively high and the main sources were seasonings and vegetables. The participants tended to prefer high levels of salt. Sodium intake was significantly higher the hypertensive individuals (stage I and II) compared to prehypertensive subjects on a normal maintenance diet. Sodium intake from vegetables was also significantly different between the two groups. Conclusion: Nursing intervention for hypertensive elderly patients should include strategies to decrease sodium intake.

Objectives: This study was conducted to examine blood pressure and other characteristics of a high sodium intake group assessed with 24-hr urine analysis and the dietary factors related to the risk of high sodium intake among Korean adults. Methods: A cross-sectional study was conducted with adults aged 20-59 years. Subjects who completed 24-hr urine collection (N = 205) were divided into 3 groups (tertile) according to the sodium intake estimated with 24-hour urine analysis. We compared the blood pressure, BMI and dietary related factors of the 3 groups (low, medium, high sodium intake group) with General Linear Model (GLM) and Duncan's multiple range test (p < 0.05). The risk factors related to high sodium intake were assessed with odds ratio (p < 0.05). Results: The sodium intake (mg/day) of the 3 groups were $3359.8{\pm}627.9$, $4900.3{\pm}395.1$ and $6770.6{\pm}873.9$, respectively, corresponding to daily salt intake (g/day) 8.5, 12.4 and 17.2, respectively. High sodium group showed significantly elevated age, BMI and systolic/diastolic blood pressure. Being male gender was associated with significantly increased risk of sodium intake (OR = 1.972; 95%CI: 1.083-3.593). The other factors related to high sodium intake were higher BMI (${\leq}25$) (OR = 2.619; 95% CI: 1.368-5.015), current alcohol consumption (OR = 1.943; 95%CI: 1.060-3.564), and having salty soybean paste with salt percentage > 14% (OR = 3.99; 95% CI: 1.404-6.841). The dietary attitude related to increased risk of high sodium intake included 'enjoy dried fish and salted mackerel' (p < 0.001) and 'eat all broth of soup, stew or noodle' (p < 0.001). Conclusions: Because high sodium intake was associated with higher blood pressure, nutrition education should focus on alcohol consumption, emphasis on related dietary factors such as using low salt soybean paste, improvements in the habit of eating dried fish and salted mackerel or eating all broth of soup, stew or noodle.

본 연구는 부모의 나트륨 섭취량과 청소년 자녀의 나트륨 섭취량이 일치하는지에 대해 파악하고, 청소년 자녀의 나트륨 섭취량에 영향을 미치는 요인을 파악하고자 하며, 그 결과에 따라 가정에서의 나트륨 섭취량을 조절할 수 있는 방안을 제시하는 것에 목적이 있다. 2015년 국민건강영양조사 자료에서 연구대상자를 영양섭취량 중에서도 나트륨 섭취량이 측정된 만 7세에서 만 18세까지의 초등학생, 중학생, 고등학생을 추출하고, 결측값을 제외하여 최종분석대상자는 405명이었다. 그리고 청소년 ID에 아버지 ID와 어머니 ID로 데이터를 매칭하여 생성하였다. 연구결과 청소년은 여자 청소년보단 남자 청소년이 ${\beta}=-.187$, 청소년의 연령이 높을수록 ${\beta}=.192$, 외식빈도가 많을수록 ${\beta}=.153$, 나트륨 섭취량이 높아졌다. 그리고 아버지보다는 어머니의 연령이 높을수록 ${\beta}=.171$, 나트륨 섭취량이 높을수록 ${\beta}=.136$으로 청소년의 나트륨 섭취량이 높았다. 이 점은 우리나라는 어머니가 주로 식사준비를 하는 경우가 많기 때문이다. 그러나 한편으로는 맞벌이 부부의 증가로 부모가 자녀의 질적인 식사를 고려하지 못하게 되어 자녀의 식사를 외식에 의존하는 경우도 적지 않을 것으로 예측되어 그러한 관점에서의 실태조사가 추후 필요하다.

Objectives: This study was performed to evaluate the consumer education program for reducing sodium intake based on social cognitive theory (SCT) and investigate consumer perceptions of environmental, cognitive and behavioral factors. Methods: Consumers (n=4,439) were recruited nationwide in Korea to participate in a nutrition education program for reducing sodium intake which was targeted on senior housewives (SH), parents (P), and office workers (OW). Questions regarding main factors of SCT were asked both before and after the education program. Results: SH and P recognized external social efforts and information to reduce sodium including nutrition labeling more than OW. The main barriers to practice reducing sodium intake were limited choice of low sodium food and menu, interference with social relationship when dining with others, and limited information, knowledge and skills. SH had lower barriers to practice reducing sodium intake and OW perceived 'preference to soup or stew' and 'preference to Kimchi, salted fish and fermented sauces' as barriers more than other groups at the baseline. Less than 50% of participants knew the relationship between sodium and salt, sodium in nutrition labeling, and recommended sodium intake. In addition, OW had little knowledge for capability to reduce sodium intake and lower self-efficacy to practice compared with SH and P. After education, positive outcome expectations such as lowering blood pressure, prevention of cardiovascular disease and osteoporosis were increased and barriers to practice reducing sodium intake were decreased in all groups (p < 0.05). The knowledge for behavioral capability and self-efficacy to reduce sodium intake were also improved but OW had still lower scores compared with other groups. Conclusions: These results suggested that nutrition education programs could be an effective tool to impact general population by facilitating awareness and increased capability to reduce sodium intake.

The aim of this study was to develop various types of a dish frequency questionnaire (DFQ) for estimating the habitual sodium intake and to evaluate the validity of a 125 item dish frequency questionnaire (DFQ 125) with the DFQ 70, DFQ 36 and DFQ 15. For the DFQ 125, one hundred and twenty five dish items were selected based on the information of sodium content of a one serving size, consumption frequency and dish items that contributed most to the variation of sodium intake. Frequency of consumption was determined through nine categories ranging from more than 3 times a day to almost never to indicate how often the specified amount of each food item was consumed during the past 6 months. The sodium intake estimated with DFQ 125 was $5775.0{\pm}3636.3mg$, 12.6% higher than that estimated with a 24 hr urine analysis ($5009.7{\pm}1541.9mg$) and significant correlation was observed between them (r=0.3315, p<0.001). When sodium content in broth leftover was subtracted from the total intake, the actual sodium intakes was decreased to $5309.6{\pm}3076.6mg$, which was 3.2% higher than that with a 24-hr urine analysis. Overall, 56% of subjects in the lowest quintile of sodium intake computed with DFQ 125 were also in the lowest of adjacent quintile while categorization into the opposite quintile were 4.9%. DFQ 70 was developed from DFQ 125 by omitting the food items not frequently consumed, selecting the dish items that showed higher sodium content per one portion size and higher consumption frequency. The sodium intake estimated with DFQ 70 ($5026.6{\pm}3107.1mg$) showed only 0.2% difference from that estimated with a 24-hr urine analysis, significant correlation with it (r=0.3199, p<0.001) and higher proportion of subjects to be classified into the same or adjacent quintile. The sodium intake estimated with DFQ 36 or DFQ 15 was also significancy correlated with that estimated with a 24-hr urine analysis (r=0.3441, p<0.001; r=0.321, p<0.001 respectively) and more. The proportion of subjects was classified into the same or adjacent quintile. However, the actual sodium intake estimated with DFQ 36 or DFQ 15 were $3534.0{\pm}1804.6mg\;and\;2508.0{\pm}1261.5mg$, respectively, 31.3% or 51.3% less than that estimated with a 24-hr urine analysis. It seems the DFQ 125 with subtraction of sodium content in broth leftover or DFQ 70 can be used quantitatively to estimate sodium intake of adults. DFQ 36 or DFQ 15 can be used as a screening tool or to assess the changes of sodium intake after nutrition education.

Purpose: Sodium intake is known to be a critical dietary factor in several diseases including cataract. Earlier studies have reported that excess intake of sodium may elevate the risk of cataract. However, little is known about this in Koreans. Thus, the purpose of this study was to examine whether dietary intake of sodium and potassium might modify the risk of cataract. Methods: A total of 1,319 males (219 cases) and 1,966 females (369 cases) from Korean National Health and Nutrition Examination Survey 2012 were analyzed. Energy adjusted dietary intakes of sodium and potassium and their ratios were evaluated to ascertain their associations with the risk of cataract. Dietary intake levels were stratified into quartiles and their risk modifying effects were estimated with logistic regression models with or without subjects' socio-economic characteristics and life styles for each sex. Results: Findings suggested that various descriptive factors were associated with the risk of cataract either in males or females. Males' intake levels of sodium and potassium and their ratios did not differ between phenotypes. Higher intakes or higher ratio was not associated with the risk of cataract. In contrast, female controls had higher intakes of sodium and potassium. Higher intake of potassium reduced the risk of cataract in females. However, such association was not retained when subjects' socioeconomic status and life styles were factored into the analysis. Conclusion: Dietary sodium and potassium intakes minimally affected the risk of cataract in Korean males and females. More studies are needed to ascertain the true pathological effect of sodium intake on cataract aetiology.

This study was carried out to investigate the acute changes in R-A-A system following lasix administration, and to evaluate the materials in plasma R-A-A system and electrolytic excretion every 30 minutes for 2 hours after lasix administration with normal high sodium Korean food, moderate sodium restriction, and severe sodium restriction, and it was concluded as followed; 1. Plasma renin activity, angiotensin II concentration, and aldosterone concentration elevated in course of time after lasix administration with high sodium Korean food, but the R-A-A system takes insignificant part because of the increasing rate was so slight. 2. Although the increasing rate of plasma renin activity reached lower levels, angiotensin II and aldosterone concentration were significantly increased after lasix administration with moderate sodium restriction. 3. It was observed that higher rise in aldosterone concentration following lasix administration during severe sodium restriction than when moderate sodium restriction. 4. Urinary sodium and potassium excretion during two hours after lasix administration showed decrease as little as the amount of sodium intake, but K/Na excretion ratio showed increase with small amount of sodium intake because of the decreasing rate of potassium was low value. 5. Sodium excretion after lasix administration reached more than 1.5 times of sodium intake, even though R-A-A reaction showed significantly. 6. As our results showed, R-A-A reaction following acute diuresis was insignificant with high sodium Intake, the increasing ratio of aldosterone concentration showed high rise compare with of plasma renin activity as little as the amount of sodium intake, and the participated rate in sodium reabsorption of R-A-A system was increased.

This study was done to explore the effect of Korean women's salt usage behavior on their sodium intake and excretion according to aging. Dietary sodium intake and salt usage behavior were analyzed to compare the difference between young and middle-aged women. One hundred fifty six young women and 77 middle-aged women without hypertension or any current medication were recruited. Body mass index, waist hip ratio, blood pressure were measured from each subject. Salt usage behaviors were surveyed with questionnaire, sodium intake with 24-hr recall method, and sodium excretion with spot urine. Middle-aged women were more obese than young women according to body mass index and waist hip ratio. Blood pressure was significantly higher for the middle-aged. Young women consumed more fats and middle-aged women more carbohydrates. Middle-aged women consumed more sodium and potassium, and excreted more sodium. Among questionnaire items, kimchi, soup or pot stew, or salted vegetables were found to be related with high sodium diet. Salted vegetables and salted nuts and potato chips were significantly correlated with young women's high sodium diet, while soy sauce on fried food, kimchi, salted vegetables accounted for middle-aged women's high sodium diet. With these results, we concluded that middle-aged women consumed more carbohydrates, less fat, and more sodium and potassium than young women. Middle-aged women frequently choose kimchi, soup or pot stew, or salted vegetables, and they contribute to high sodium intake. We recommend to choose low-salt kimchi, less soup or pot stew, and more fresh vegetables for lower sodium diet.
