The purpose of this study was to investigate the differences in food and nutrient intake by smoking status among Korean. Food and nutrient intake in relation to smoking status was studied in 7,370 adults, aged 20 years and older in 1998 Korean National Health and Nutrition Survey, in which 24 hour recall method was used for dietary survey. Information of subject's smoking status was collected by interview as a part of health behavior survey. Analysis of variance was used to test the differences in food and nutrition intake among subjects following after Duncan's multiple range test among four different smoking exposure categories. Food intake of male ex-smoker was the highest in most of the food groups among the four groups of daily current smoker, occasional current smoker, ex-smoker and never smoker. There was significant differences observed in food intake of sugar, fruits, beverage, seasoning by the smoking status. It had been also observed that significantly high intake of energy from carbohydrate in non smoker compare to current smoker especially in male subjects. Fiber and vitamin C intake was also higher among non-smoker (never smoker and ex-smoker) than current smoker. In general, food and nutrient intake pattern of ex-smoker resembled those of never smoker than those of current smoker. Not likely the observation from European and American studies, fat intake was not statistically different between smoker (current) and non-smoker (ex-smoker and never smoker) among Korean.
This study was designed to obtain the information concerning food intake, dietary habits, functional status, health condition and cognitive status of the elderly using public health center in Ulsan area. The subjects of this study consisted 154 elderly persons aged 60~82 years. Interviews were conducted using the health habits and food frequency questionnaires to provide basic information for nutrition education program. We evaluated the current food intake, dietary cholesterol intake (cholesterol index), functional status, cognitive function and blood analysis of the subjects. The results of this study were as follows : Mean age of the subjects was 68.7 $\pm$ 6.7years. The average cognitive status score of the subjects was 7.9 $\pm$ 2.0 (full score was 10.0). Male had a higher cognitive status score than female. There was significant difference between cognitive status score and age, education level, pocket money, physical activity and living condition. The subjects who had a higher cognitive status score ate more fish and meats group and milk and milk products than the subjects had a lower cognitive status score. And hemoglobin level, serum triglyceride, HDL-cholesterol and atherogenic index affected to cognitive status while fasting blood glucose and LDL-cholesterol did not any effect on cognitive status. These results have demonstrated that various socioeconomic variables and food intake pattern and nutritional status affect on cognitive status with aging and suggest that proper nutrition education and adequate nutrient intake in quality and quantity are essential in maintaining cognitive status in later life.
This study was intended to examine the zinc status of free-living adult women living in the Taegu region. Zine intake of 102 female subjects was measured by food frequency method for 3 consecutive days. Urinary zine was assessed from urine samples collected fir twenty four hours. Average dietary zinc intake of adult female subjects using food record was 5.9$\pm$1.8mg which was 49$\%$of Korean RDA. When zine intake by frequency method was higher than by food record. Average urinary zine intake by frequency method was higher than that by food record. Thus, it appeared that zinc intake by frequency method was higher than that by food record. Average urinary zinc excretion of 102 adult female subjects was 0.28$\pm$0.16mg, which belonged to marginal zinc deficiency range. Fifty nine of 102 subjects showed marginal zinc deficiency as assessed by urinary zinc excretion. If we compare the zinc status of adult female subjects by age group, zinc intake in the 50s was significantly higher than any other age groups. However, there were no significant differences in zinc status according to BMI groups and BMI groups. Significant correlations were found between zinc intake and energy, protein, carbohydrate and fat intake. Based on dietary zinc intake and urinary zinc, we concluded that zinc status of adult female living in the Taegu region is marginally deficient.
This study was done to investigate the relationship of socioeconomic status and food intake to cognitive status of the older population. The subjects of this study consisted of 214 older persons aged 60 - 84 years. Interviews were conducted using the health-related habits and food frequency questionnaires to provide basic information for nutrition education program. We evaluated the current food consumption-pattern and cognitive status of the subjects. The results of this study were as follows: Mean age of the subjects was 69.7${\pm}$7.4 years. The average cognitive function score of the subjects was 7.9${\pm}$2.0 (full score was 10.0). Male had a higher cognitive status score than female. There was significant difference between cognitive status score and age, education level, pocket money, physical activity and family type. The subjects who had a higher cognitive status score ate more fish and meats group and milk and milk products than the subjects that had a lower cognitive status score. These results have demonstrated that various socioeconomic variables and food intake pattern affect on cognitive status with aging and suggest that proper nutrition education and adequate nutrient intake in quality and quantity are essential in maintaining cognitive status in later life.
BACKGROUND/OBJECTIVES: This study aimed at evaluating the dietary intakes of Korean adolescents affected by food insecurity, in comparison with those who were food secure. SUBJECTS/METHODS: The study used one day 24-hour dietary recall data from the $6^{th}$ Korea National Health and Nutrition Examination Survey. The study subjects consisted of 1,453 adolescents of whom 695 were middle school-aged and 758 were high school-aged. Food security status was assessed using the 18-item questionnaire. Nutrient intake was evaluated in terms of nutrient density, insufficient intake, and excessive intake for selected nutrients, in addition to meeting the appropriate range for total energy intake and energy intakes from carbohydrate, sugar, protein, fat, and saturated fatty acids. Food intake was evaluated in terms of food group servings and dietary diversity score (DDS). RESULTS: The percentages of food insecurity were 11.1% for middle school-aged adolescents and 16.8% for high school-aged adolescents. Food insecure middle school-aged adolescents had higher intake of carbohydrate (P = 0.006) but lower intake of fat (P = 0.010) and saturated fatty acids (P = 0.005) than their food secure counterparts although the intake of both groups was in the recommended ranges. Nutrient intake among high school-aged adolescents was generally similar regardless of food security status. Both food secure and insecure adolescents showed insufficient intake of vitamin A, vitamin C, and calcium, and excessive sodium intake. They additionally had low prevalence of meeting appropriate intake ranges for energy, carbohydrate, and sugar. Food intake in terms of food group servings and DDS was also similar regardless of food security status among both age groups, with low intakes of foods from fruit and dairy groups. CONCLUSIONS: Except for a few nutrients among the middle school-aged adolescents, dietary intakes among Korean adolescents did not differ by food security status in this study.
The purpose of this study was to analyze the relations among the three factors: 1) characteristics of family, 2) nutrient intake status and 3) academic achievements. The subjects in this study were 7,698 boys and girls attending primary, middle and high schools in South Korea. The questionnaire was made and distributed to the student to answer the questions about family background and food intake status. Food intake frequency method was used to examine nutrient intake status. Academic achievement results of last semester were taken from students school records. Followings are the results of the study:1. Most of the mean nutrient intakes were above the Korean recommended dietary allowances. However, calcium, iron, and vitamin A intakes were below the Korean recommended dietary allowances. Therefore, it is recommended to increase the intake of these nutrients in these students to meet the RDA.2. Total amounts of food intake were decreasing in higher grades and food intake of boys was higher than that of girls. 3. Educational period of parents and economic status of family had grades influences on student's academic achievement and nutritional status. The students with parents of higher education and higher economic status had better academic achievement and balanced nutritional status. 4. When students were divided into three groups with respect to the percentage of recommended nutrient intake, the group with nutrient intake of 75-125% of RDA achieved better academic achievement than other groups. In conclusion, educational length and economic status of parents and optimal intake of nutrients (75-125% of RDA)by students significantly affected academic achievements of the students.

This study was conducted to evaluate the health status, life style, dietary habits and nutritional status of 44 industry workers that were routinely exposed to unclean environments while consuming 3 major pork dishes 2 times a week for 6 weeks. The health status, life style and dietary habits of the workers were investigated by a survey questionnaire, and the nutritional status was evaluated using the 24-hour recall method. Overall, the subjects reported that their health status was fairly good throughout the year, but that they felt dizziness and fatigue often. In general, the subjects did not exercise regularly and drank alcohol very often. The average daily energy intake increased from 1,708.3 kcal to 1,859.5 kcal without a change in the BMI or WHR when the respondents were fed pork dishes. However, the mineral intake did not differ significantly in response to the consumption of pork, although the Zn intake tended to increase. Moreover, the vitamin $B_1$, niacin, and E intakes increased after consuming pork(p<0.05), while the cholesterol intake decreased from 425.2 mg to 356.7 mg after eating pork(p<0.05). Additionally, both the fat intake and the PUFA intake increased after the consumption of pork with the intake of oleic, linoleic and linolenic acids increasing significantly(p<0.001). Finally, the intake of essential amino acids also increased significantly in response to the consumption of pork(p<0.01). Based on the results, regular consumption of pork dishes improved the nutritional status of industry workers without any adverse effect in terms of the intake of relative fat and cholesterol.
The purpose of this study was to examine household food insecurity and the associations of food insecurity with socioeconomic characteristics, food behaviors, health status and nutrient intake among elderly people in a rural area. This study included 191 elderly people (mean age = $72.0{\pm}7.4$) in Jeollabuk-do, Jangsu-gun. House food insecurity was measured using an adapted version of the USDA short form household food insecurity scale, and nutrient intake measured by a 24-hour dietary recall. Only 15.2% of the subjects were in food-insecure households, 84.8% of the elderly households were food-secure. The food-insecure households were significantly lower in the number of family, frequency of shopping, and perceived health status than the food-secure households. In addition, they had serious tooth problems and NSI (Nutrition Screening Index) scores. Food-insecure households were significantly lower in most areas of nutrient intake (energy, protein, fat, Ca, P, Fe, K, Na, Zn, Vit. $B_2$, niacin, Vit. E), and also lower in nutrient intake compared to dietary reference intake (energy, protein, P, Fe, K, Na, Vit. $B_1$, Vit. $B_2$, niacin, Vit. E). These results suggest that the household food insecurity measures used in this study were an important indicator of nutritional well-being among elderly persons in the rural area. Food insecurity should be considered an important issue to public health and food service programs should be expanded for food-insecure households in rural areas.
A survey was carried out to investigate relation between life stress and nutrient intake status in female university students. It was represented that increasing trends of food intake under the stress condition and preference taste was sweet and hot in female students. The female students thought that food intake for coping with stress was produced negative results and they perceived the relation between stress and their health problem. There was a positive correlation between stress level and the change of food intake in female students statistically(p<0.01). They had higher stress in future prospect, academic problem, friend relationship, personality and family relationship. The average calorie intake of female university students was 1553.06kcal(77.65% of RDA). The intake of protein, calcium and iron were quite less than the RDA, whereas the intake of phosphate, vitamin A, $B_2$, C, niacin were more than the RDA. In changes of nutrient intake under the stress conditions, the higher stress group had decreased intake of calcium, iron, vitamin $B_1,\;B_2$, C than the lower stress group(p<0.05).
Previous studies have shown that sodium excretion is positively related to calcium excretion in the urine. As excessive sodium intake is a common nutritional problem in Korea, we intended to investigate associations among sodium intake levels and calcium status, evaluated by 24 hour recall method and urinary excretion, and bone status. We collected dietary information for non-consecutive three days from 139 young adult women 19~29 years. After classifying the subjects into 4 groups based on the dietary sodium levels by daily total sodium intake (mg) and sodium density (sodium intake per 1000 kcal energy intake), we compared the bone status, nutrient intakes, urinary calcium and sodium excretions. The results showed a positive association between total daily sodium intake and intake of other nutrients. However, no significant differences in nutrients intakes were observed among subject groups classified by sodium density levels. There were no significant differences of bone density among groups by total daily sodium intake as well as by sodium density. While total daily sodium intake showed significantly positive relationship with urinary sodium (p < 0.05) and calcium (p < 0.05), sodium density was not related to urinary excretion of calcium and sodium. Our results suggested that promoting balanced meals providing appropriate amounts of energy intake is the essential component of nutrition education for improving calcium status of young Korean women with excessive sodium intake.
