It is necessary to compare the dietary characteristics among different age groups because different nutritional problems require different dietary applications. This study was performed to identify the nutritional characteristics of Korean diet among different age groups. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living in Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. Energy intake was as much as 1771kcal for PC, 2139kcal for EC, 2475kcal for HS, 2276kcal for CS, 1860kcal for 30-49 years, 1715kcal for 50-69 years, 1326kcal for over 70 years. The subjects of PC, EC, HS, and CS groups got about 25% of energy from fat, but the subjects in 30-49 years, 16%, those in 50-69 years, 15%, and those over 70 years, 13%. The energy consumption from protein was about 15% in each age group. Percent of energy intake as Korean RDA was greater than 100% for PC, EC, HS, and male CS groups. The percent intake for RDA of calcium, iron, vitamin A, and vitamin B$_2$was low in most age group. Iron intake was inadequate in female of PC and CS groups, and subjects in 30-49 years and over 70 years. Mean adequacy ratio(MAR) was 0.9 in PC, and decreased with increase of age. Therefore MAR did not reach to 0.7 among subjects over 70 years. Index of nutritional quality(INQ) for calcium, iron, vitamin A, and vitamin B was below 1 in most age groups. From these results, major nutritional problems of each age group were overall inadequate intakes of calcium and iron, excess consumption of protein and fat for PC, EC, HS, and CS groups, and inadequate nutrients intake of subjects over 70 years old. According to these results, each age group seems to need specific nutritional intervention. (Korean J Nutrition 34(5) : 554~567, 2001)

This study was performed to assess diet qualities by sexes and ages of adults over thirty years old in Jeon-ju area. Diet survey with one day 24-recall method was used done for 382 subjects(129 males & 253 females). Survey sample was divided into six groups by sex and age groups: male 30-49, male 50-64, male 50-64, male 65-79, female 30-49, female 50-64 and female 65-79 years. Diet quality was assessed by NAR(Nutrient Adequacy Ratio), MAR(Mean Adequacy Ratio), INQ(Index of nutrition quality), KDDS(Koreans Dietary Diversity Score), Meal Balance, DVS(Dietary Variety Score), DQI(Diet Quality Index). The 5-point DQI assessed the important dietary guidelines for Koreans. The averages of energy, protein, P, vitamin B$_1$, vitamin B$_2$, niacin and vitamin C intakes were higher than 70% of RDA. The averages intakes of Ca and vitamin A were very lower than RDA all groups. The averages of MAR were 0.78, 0.81, 0.83 in male 30-49, 50-64, 64-79 years, 0.73, 0.77, 0.71 and in female 30-49, 50-64, 65-79 years, respectively. The averages of MAR in female 30-49 years and female 65-79 years were significantly lower than the averages MAR of male 65-79 years. The averages of Sugars and Beverages intakes were significantly higher in male 30-49 years than others. Animal food intake ratio(% total food intake) in the male 65-79 years(16%) was significantly higher than male 30-49 years(11%). The averages of Nutrition intakes were higher in male compared to female. The subjects who consumed all of the major five food groups were 5% in male 30-49, 17.8% in male 50-64, 25.0% in male 65-79 years, 18.9% in female 30-49, 23.7% in female 50-64, 11.5% in female 65-79 years. The averages of KDDS were 3.5, 3.9, 3.9, 3.8, 3.8, 3.5, respectively. The averages of Meal Balance were 8.6, 9.1, 9.1, 8.3, 8.4, 7.8, respectively. The averages of DVS 20.1, 19.9, 19.9, 20.5, 19.0, 17.2, respectively. The averages of DQI were 1.7, 2.2, 2.1, 2.0, 2.1, 1.7, respectively. 81.8% of the subjects had KDDS scores of 2 to 4 and 87.3% of the subjects has Meal Balance scores 4 to 10. In contrast, 89.8% of the subjects had DQI scores of 0 to 3. In view of these facts there are few who observed the five dietary guidelines for Koreans. There findings suggest that dietary qualities were associated with nutrient intake the relation factors may vary by sex and age of adults over thirty years old in Jeon-ju area. Common problems were lack of Ca, vitamin A and dairy products intakes. Therefore adults over thirty years old in Jeon-ju area need the important nutrient management such as Ca, vitamin A.

This study was conducted in order to measure changes in the dining out consumption behaviors of the elderly living in Korea. Data on 2,316 and 3,170 elderly aged over 50 years were extracted from the 2001 and 2011 KNHANES(Korea National Health and Nutrition Examination Surveys), respectively. The data were analyzed by gender, age, region area, marital status, educational level, household income, economic activity and subjective health status. Frequency of dining out was higher in males between 50~64 years of age, living in metropolitan area, well-educated, high-income, engaged in economic activity and healthy. As a result, these basic data can be used for analyzing the changes in dining out consumption behaviors by sociodemographic characteristics of people aged over 50 years and the elderly in Korea. In the results on the consumption rate of food service in the two groups, 'female' and '65~74 years old' showed the largest increases from 10 years, and thus should be the group that the food service industry focuses on to develop new marketing strategies suitable for the environment.

Objectives: This study aims to investigate the estimated proportion for influenza vaccination and to identify factors associated with influenza vaccination in Korean adults aged 50 and older with asthma. Methods: Data from 2010-2015 Community Health Survey(n=23,662) was used. A chi-square test was performed to investigate the estimated proportion for influenza vaccination, and a multiple logistic regression analysis was used to identify the factors associated with self-reported influenza vaccination. Results: In men, 42.3-49.5% of asthma patients 50-64 years of age, and 78.5-90.2% of elderly (over 65 years of age) asthma patients received influenza vaccination. In women, 49.7-61.9% of asthma patients 50-64 years of age, and 82.7-89.7% of elderly asthma patients received influenza vaccination(p<0.0001). Low education level, non-smoking, non-drinking, hypertension, diabetes and use of public center were related to high influenza vaccination in 50-64 years old men with asthma. Low education level, non-smoking, bad health status, hypertension, diabetes and use of public center were related to high influenza vaccination in 50-64 years old women with asthma. Non-smoking and use of public center were related to high influenza vaccination in over 65 years old men with asthma. White-collar jobs, smoking, absence of hypertension and use of public center were related to low influenza vaccination in over 65 years old women with asthma. Conclusions: Influenza vaccination remains relatively low in asthma patients 50-64 years of age. It is necessary to recommend vaccination to asthma patients, provide them with information, and devise other strategies to improve vaccination.

Unhealthy dietary behavior such as insufficient calcium intake can be one of risk factors of osteoporosis and chronic diseases in older people. This study evaluated the recent trends in dietary calcium intake and the food source in Korean adults aged 50 years or older using the Korea National Health and Nutrition Examination Survey (KNHANES, 2015-2019) data. This study used 24-hour recall survey data to investigate the calcium intake, the major food groups and main dishes contributing to the calcium intake. The mean calcium intake was 479.55-506.81 mg/day. The major food groups that contribute to calcium intake were vegetables, milks and fishes. Dairy and frozen desserts and kimchi were the major dish groups that contributed to the calcium intake. Calcium intake from milk in dairy and frozen dessert group has been high in last 5 years (50-64 years old: 34.71-47.68 mg, 65-74 years old: 29.72-43.65 mg, over 75 years old: 22.91-42.93 mg). In addition, baechu-kimchi is the most contributed to the calcium intake in kimchi group (50-64 years old: 35.10-41.47 mg, 65-74 years old: 29.62-34.96 mg, over 75 years old: 23.79-29.13 mg). In conclusion, various source of calcium needs to be recommended to increase intake calcium in over 50 years, which may reduce chronic diseases and improve quality of life.

This study focused on the nutrition knowledge, food purchase behaviors, and dietary habits of 213 housewives (41 women under 39 years, 98 women 40~49 years, and 74 women over 50 years). Younger housewives held more special jobs, whereas older housewives worked as housewives or had no jobs ($p$<0.05). The average monthly income of the three family groups was 3,000,000~5,000,000 won, and the monthly dietary expenditure for all three groups was 200,000~500,000 won. Familial frames for the three groups was nuclear family (over 80%), but housewives younger than 39 years (19.5%) lived together with their parents and let them take care of their children. Housewives (over 50 years) prepared a balanced diet for every meal, utilized less drastic cooking methods to prevent loss of nutrients, and shopped at many places in order to save money on various food materials. Further, they purchased food materials that resulted in the least amount of left overs. On the other hand, housewives under 39 years visited large supermarkets and purchased cooked foods more than other groups. Housewives under 39 years considered nutrients content as the most important factor when purchasing food materials, whereas 74.5% of housewives between 40~49 years and 51.4% of housewives over 50 years put the most importance on flavor ($p$<0.05). Housewives under 39 years were interested in manufacture date, nutrient content, and food price, in decreasing order, whereas housewives between 40~49 years and over 50 years were interested in manufacture date, food prices, and nutrient content. Older housewives were interested in brown rice and fruits, whereas younger housewives under 39 years were interested in meat, fish, eggs, fried foods, and fast food. Older housewives over 50 years did not consume fried foods more than two times per week and consumed three regular meals more often than younger housewives. Accordingly, for younger housewives, it is necessary that healthy foods be cooked for their families.

This study was conducted to identify the characteristics of Korean diet in the view of food and food group intakes. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. Rice was a major contributor to many nutrients intake because of the amount of consumption. Vegetable oil made great contribution to fat intakes and eggs, squid, and anchovy supplied much cholesterol compared to other foods in all the age groups. Milk was major contributor of fat and cholesterol as well as calcium in younger age group, and seasoning gave much contribution to iron intakes. Mean dietary variety score(DVS) was 32 for EC group and 17 for subjects over 70 years, and tended to decrease along the increasing age. EC group consumed most variable number of foods of all groups but they consumed many junk foods, therefore the MAR value was low despite their high DVS value. Mean dietary diversity score(DDS) of each age group from PC group to subjects over 70 years was 4.34, 4.28, 3.79, 3.89, 3.76, 3.56, and 3.25, respectively. Food group, which was consumed below the minimum amount, was mainly fruits in all the age groups, and many subjects in HS group and over 30 years consumed dairy products below the minimum amount. From these results, age specific nutritional problems were found. PC group and subjects over 50 years seemed to need more diverse food intake than now, EC group did nutrient dense food, and HS group and subjects over 30 years did dairy products. Also, subjects took various nutrients from rice and seasoning contributed to some nutrients intakes. (Korean J Nutrition 34(5) : 568∼579, 2001)

This study was performed to analyse some rick ffactors for chronic degenerative diseases of the Korean dict. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living in Seoul and the surrounding areas. The subjects over 30 years old were classfied to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. The dietary risks for chronic degenerative disease such as food sources of fat consumption, high cholesterol intake, low dietary fiber intake, and low calcium intake and high protein intake were analyzed. Younger subjects had more animal fat proportion than older subjects did. HS and CS had the least fat proportion from fishes and shellfishes. Each mean cholesterol intake of PC, EC, HS, and CS was over 300mg/day, and HS load the highest level of 415mg/day. Cholesterol density of the diet of PC was the highest of 175mg/1000kcal and the level decreased when the age increased. The subjects consuming cholesterol over 100 mg/1000kca1 were about 70% of PC and HS. More than 20% of PC, EC, and HS consumed calcium under 75% of RDA with protein consumption over 125% of RDA. Dietary fiber intakes were 18g for HS, CS, 30-49 years, and 50 ∼ 69 years, 14g for EC and over 70 years, and 12g for PC. Ninety percent of PC and EC, 80% of HS and CS, and 70% of tole subjccts over 30years consumed dietary fiber under the level of 10g/1000kca1. The major food sources of dietary fiber were vegetables and grains. From these results, children and adolescents had ricks for chronic degenerative diseases on all the analyzed items. The results of this study would provide the basic information for development of dietary interventions to improve diet find health.

Background: Due to an increasing number of workers aged 50 years and above, the number of those employed is also on the rise, and those workers aged 50 and over has exceeded 50% of the total fatal occupational injuries. Therefore, it is necessary to implement the selection and concentration by identifying the characteristics of high-risk groups necessary for an effective prevention against and reduction of fatal occupational injuries. Methods: This study analyzed the characteristics of high-risk groups and the occupational injury fatality rate per 10,000 workers among the workers aged 50 and over through a multi-dimensional analysis by sex, employment status of workers, industry and occupation by targeting 4,079 persons who died in fatal occupational injuries from January 2007 to December 12. Results: The share of the workers aged 50 years and above is increasing every year in the total fatal occupational injuries occurrence, and the high-risk groups include 'male workers' by sex, 'daily workers' by worker's status, 'craft and related-trades workers' by occupation, and 'mining' by industry. Conclusion: The most frequent causal objects of fatal occupational injuries of the workers aged 50 years and above are found out to be 'installment and dismantlement of temporary equipment and material on work platforms including scaffold' in the construction industry and 'mobile crane, conveyor belt and fork lifts' in the manufacturing industry.

This study was conducted to analyze blood lipid profile and other risk factors among crew members who are currently active and had more than 10 years of experience as crew members. Data was analyzed using medical record files in an airline medical department. The results are as follows. 1. The total number of crew members studied was 392. Among age groups, those below age 40 consisted of 26(6.9% of the total), those in age $41{\sim}50$ were 135 (34.4%) and those over age 51 were 230 (58.7%). 263 were former air force pilots consisting 66.9%. Those who had captain status numbered 21 I comprising 53.7% of the total. The type of aircraft most of the crew members involved were large size aircraft which totaled 268 (68.2%). With respect to the number of working years as crew members, 488(48.9%) comprised the largest group with $11{\sim}15$ years. 2. The rate of smoking among crew members has shown gradual decrease with 50.3% smoking in 1983 to 33.6% in 1993. Among $41{\sim}50$ age group the rate has shown a decrease from 20.9% to 13.3% In those group over age 51 it decreased from 25.5% to 16.6%. But group below age 40 were within the range of 3.6~3.8% with no significant change in the rate of smoking. 3. Body Mass Index in age group over 51 was slightly higher than other age groups. On the whole, BMI over 25 was not found. 4. The total cholesterol levels of those below age 40 were $196.9{\pm}38.5mg/dl,\;216.2{\pm}39.2mg/dl$ in ages $41{\sim}50$, and $225.1{\pm}42.5mg/dl$ in age group over 51. No significant difference was found among age groups. 5. HDL-cholesterol levels of over age 50 were higher than other age group and ranged from $40{\sim}55mg/dl$. 6. LDL-cholesterol levels of those over 51 were $126.7{\pm}37.7mg/dl$ higher than other age groups. But there were no significant changes in all age during 10 years of follow up. 7. Cardiac index of age group below age 40 was 3.8, 4.3 in age group $41{\sim}50$ and 4.5 in those over age 51 group. No significant changes among groups were found during the follow up period. 8. Triglyceride levels of age group below age 40 was $142.2{\pm}70.1,\;167.3{\pm}77.5$ in age group of $41{\sim}50$ and $113.6{\pm}897$ in age group over 50 showing that triglyceride levels increased with age. No significant changes in pattern were noted.
