Age specific characteristics in Korean diet and their changes were analyzed with the demand model including the number of family members by age group as independent vasiables Urban household budget data, 773 household data in 1977 and 947 household data in 1983, was applied to the demand model. A series of F-test was carried out to set up the age groups by food item. The main results can be summarized as follows; 1. Food consumption patterns are remarkably different between 0-13 years old age generation and over 40 years old generation. The 0-13 years old generation reveals higher preference for milk, wheat product, fruit and milk and lower preference for rice and vegetable than any other age generation. This characteristics of the childhood diet has been formed In the generation born after 1970's and thus will be reserved as their generational characteristics. On the other hand, over 40 years old age group prefers rice and fish to fruit, milk and wheat product. Therefore we can conclude that over 40 years old age group maintains the traditional Korean diet pattern. 2. The preference for fish is low. in 20-30 years old age group than in any other age group and wheat product is Preferred highest in 6-13 years old age group of all age groups. Meanwhile the most remarkable change In food consumption pattern is shown in meats and vegetables. Namely in 30 40 years old age group the preference for meat has increased substantially and that vegetable has decreased to a great extent. 3. The declining per capita consumption of rice spreads like a wave to higher age. groups, but over 40 years old age group bas played an important role in reducing the decreasing rate of rice consumption. In order to restrain the declining rice consumption a special integrated food policy is required to induce rice consumption in less 30 years old generation.

Purpose: The purpose of this study was to investigate the correlation between shoulder pain and disability index (SPADI) with participation in badminton and to find the effects of badminton on the shoulder joint. Methods: A questionnaire was answered by 143 people with shoulder pain and disability in badminton clubs located in Busan, Gyeongsangnam-do. Out of the 143 subjects (91 males, 52 females), about half (72 people) were over 40 years old, with 71 people over 50 years old. The questionnaire contained 27 questions involving demographic participation characteristics, playing characteristics, and SPADI. Data analysis was performed using the SPSS statistics program to conduct frequency analysis, cross analysis, the t-test, and one-way analysis of variance. Results: The correlation between badminton career, frequency of play, and SPADI was statistically significant. There was a significant increase in SPADI scores for players over 40 years old. The over 40 year old group with less than 5 years of badminton had a significantly increase in SPADI score. The over 50 year old group showed a significantly lower SPADI score compared with the over 40 group. Conclusion: We suggest that beginner badminton players learn correct posture and badminton skills from professionals, participate regularly, and maintain an appropriate intensity/frequency of badminton.

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.

Objectives: Menopause is associated with adverse metabolic changes in plasma lipoprotein and inflammation markers. Estrogens have beneficial effects on lipid metabolism and inflammation. Isoflavones (ISO) have structurally similar to estradiol. Our objective was analize the effect of soy-ISO on serum lipid and inflammatory markers (sP-selectin and sCD40L) in postmenopausal women. Methods: A 12-week randomized, double-blind, placebo-controlled intervention with soy-ISO (50 mg, twice daily) was conducted in 35 healthy postmenopausal women (55-72 years old). The women were divided in 2 groups: 20 were allocated to soy-ISO, and 15 to a placebo group. Results: The changes of total cholesterol (TC), triglycerides, low-density lipoproteins-cholesterol (LDL-C), high-density lipoprotein-cholesterol, Apo-A1, sP-selectin and sCD40L in 2 groups before and after 12-week treatment showed no statistical significance. In subgroup analysis, soy-ISO supplementation significantly decreased the levels of TC, LDL-C and sCD40L in women under 65 years old, and with null effects on serum lipid and inflammation markers in women over 65 years old. Conclusions: Soy-ISO did not significantly favorable effects on the lipid profile and inflammatory markers in postmenopausal women. However, in women under 65 years of age, soy-ISO significantly decreased the TC, LDL-C and sCD40L, whereas, no effects on lipid profile and inflammation markers in women over 65 years old were observed.

Purpose: This prospective study was designed to investigate the prevalence of urinary incontinence (UI), voided volume, post void residual volume (PVRV), daytime frequency and nocturia in women over 40 years. Methods: The sample comprised of 302 women over 40 years.The study lasted from February 2008 to November 2009. Data about daytime frequency and nocturia were gathered from 48 hour bladder diary. Further, a PVRV was assessed through a bladder ultrasonography. Data were analyzed using the t-test, Mann Whitney test, Kruskal Wallis test and multiple regression. Results: Although the prevalence of UI among the women was as high as 70.5%, the perception rate of UI was as low as 10.8%.Single voided volume of women without or with UI was 223 mL or 198 mL (p<.001), respectively; PVRV, 25.8 mL or 23.6 mL (p=.055); daytime frequency, 5.89 or 6.96 (p<.001); nocturia, 0.99 or 1.23 (p=.040). Age (${\beta}$=0.19, p=.001), single voided volume (${\beta}$=-0.16, p=.006), and nocturia (${\beta}$=0.12, p=.034) were associated with UI. Conclusion: The prevalence of UI was found to be 70.5% among the participants. The assessment of single urinary volume and nocturia through a bladder diary lends support to identifying UI for women over 40 years.

A convenience samples of Korean-Canadian/American adults who lived in Vancouver, San Hose and Los Angeles areas for over 10 years, were studied in 2000. Total of 130 adults were analyzed by immigration age. The age of immigration age was divided into 3 groups: the young group immigrated at 25 or before, the middle group immigrated at 26 to 40, and the old group immigrated at over 40. Their average length of residence in Canada and the U.S. was a little longer than 20 years. The dietary behavior patterns were similar among 3 groups, except co-eaters and dining-out frequency, and the Korean-Canadians/Americans seemed to be more home-based, family-tightened and traditional patterns than Koreans in Korea. They liked Korean traditional basic dishes, but their children liked a-la-carte ones and immigrants at early 20's showed similar food preferences as young generations. The attitudes of dietary acculturation for themselves and for their children were high. Since immigrating at age 26 to 40 years old rather than 20's or over 40's, showed stronger acculturation attitudes even with no significance and revealed significantly differences in some dietary behaviors and food preferences, it is recommended that immigration age should be considered when planning dietary foodservices at nursing care systems for Korean Canadians/Americans.

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.

Objectives: The purpose of the study is to investigate the influencing factors of metabolic syndrome on the periodontal disease in the Korean adults over 40 years old. Methods: The data were extracted from the Fifth National Health Nutrition Survey 2010. The subjects were adults over 40 years old. The periodontal diseases were examined by direct survey. The questionnaire consisted of the general characteristics of the subjects, oral health behavior, metabolic syndrome, and relation to periodontal diseases. CPI(community periodontal index) was measured. CPI indicates periodontal condition and classified into alveolar arch of the upper jaw and the lower jaw. A periodontal disease is defined as $CPI{\geq}3$(over 4 mm). The variables for metabolic diseases included hypertension, diabetes mellitus, dyslipidemia, and obesity measured as BMI. Results: Diabetes mellitus is closely related to periodontal diseases prevalence. Low level of HDL increase the periodontal diseases. Number of toothbrushung, use of dental floss and interdental toothbrush as for the number of toothbrushing, more than twice toothbrushing a day, and use of dental floss and interdental toothbrush reduced periodontal diseases. Conclusions: The risk factors of periodontal disease in Korean adults over 40 years old were sex, age, residence, monthly income, education level, smoking, diabetes and low HDL cholesterol.
