Cancer prostate is the most common solid malignancy in males of developed countries. With increasing knowledge of the aetiology, pathogenesis and natural history of the disease, influences of dietary factors on prostate cancer development have become more evident. There is ample evidence in the literature of significance of dietary constituents for prostate cancer including vitamins A, D and E. Different vitamins have been found to effect the growth and proliferation of prostate cancer cells as evident in epidemiological, experimental and clinical studies. Various factors play the major role in determining the relationship between these vitamins and prostate cancer in terms of environmental, pharmacological, or genetic aspects. To explore these aspects, the present article reviews the literature on the present status of vitamin use for prevention and management of prostate cancer.
The present study was undertaken to investigate the effects of excess vitamin E supple-mentation (0.5%) and cholesterol (0.5%) on levels of serum and liver vitamin E and cholesterol in two categories of rats, group A and group B. Rats in group A(45-65g) were fed experimental diets for 3 weeks ( I-C, II-E, III-Ch, IV-ECh). On the other hand rats in group B(45g-65g) were first fed control diet for 3 weeks and then fed experimental diets when they were 100-l20g for the subsequent 3 weeks ( I'-C, II'-E, III'-Ch, & IV'-ECh). The levels of serum vitamin E were higher in vitamin supplemented groups as expected. Dietary cholesterol showed a tendency to lower serum vitamin E levels of vitamin E supplemented groups. Serum cholesterol levels tended to stay in a narrow range showing resistancy to dietary cholesterol and were not affected by vitamin E status. Whereas vitamin E supplementation seemed to lower the levels of hepatic cholesterol in both groups A & B( I-C, I'-C vs II-E, II'-E ), simultaneous supplementation of vitamin E with 0.5% cholesterol appeared to increase further the hepatic cholesterol levels which were already increased by cholesterol feeding ( IV-ECh, IV'-ECh, vs III- Ch, III'-Ch). Hepatic vitamin A levels decreased as rats grew older during the experimental period. Even though vitamin A levels did not differ from each other significantly, excess amount of vitamin E supplementation in group B seemed to show a tendency to decrease the vitamin A storage in liver.
Iron intake and nutritional status of 99 female college students of Chungnam Natiional Unive-rsity were estimateed with dietary survey and measurement of hematological indices including the level of serum ferritin Food intake was measured using the weighing method and iron availability per meal was calculated according to Monsen and Hallberg. The average daily intakes of protein vitamin C. total iron and also total available amount of iron were higher than the Korean R.D.A. The blood indices for iron status however showed that iron status of the subjects was inade-quate. Furthermore the serum ferritin levels indicated marginal iron storage in 75% of the subjects.
This study was carried out in order to investigate the status of food and nutrient intakes depending on the types of chronic disease of the elderly at welfare centers in Seoul. The total number of subjects was 299 elderly over the age of 60 (82 men and 217 women); they were grouped by the disease status: normal, cardiovascular disease (CVD), diabetes mellitus (DM) and arthritis patients groups. The dietary intakes were obtained by a 24-hour recall and analyzed by CAN-Pro 4.0; they were then compared with the dietary reference intakes for the Korean (KDRIs). In the results of anthropometric data according to chronic disease, the waist circumference of the normal group in males and females was lower than the other groups; in particular, the normal female group showed a lower level of waist-hip ratio, body mass index (BMI) and body fat % than those of the other groups. The arthritis group showed a higher intake of milk products than the other groups (p < 0.05); consequently, calcium intake was significantly higher than that of the other groups (p < 0.001). Vitamin A intake in the arthritis group was significantly higher than the intake in the normal and DM groups (p < 0.01). Normal and arthritis groups showed significantly higher intake of zinc and copper than the CVD group (p < 0.01). In general, about 80% of the subjects in this study revealed insufficient intakes of riboflavin, vitamin C, calcium, dietary fiber, vitamin D, biotin and potassium, compared with the estimated average requirement (EAR) or adequate intake (AI). However, sodium intake of all groups was higher than the AI of KDRIs. In conclusion, nutrient intake, according to the chronic disease, showed significant difference in some of the micronutrients, vitamin A, Ca, Zn and Cu. Therefore, we suggest that dietary guidelines, such as reducing the intake of salty foods and sweet drinks and increasing the intake of foods with sufficient calcium, vitamin D and vitamin C, are necessary to the improvement of eating habits for the elderly.
This study was conducted to investigate the effects of residence types ((1) parent house, (2) dormitory or boarding home, (3) boarding home w/o food) on the dietary habits and health status of college women (20-23 y). Overall, 46.1% of college women reported that they were economically middle class and spent 200,000-390,000 won. Additionally, 17.4% of college women considered themselves healthy, while 33.8% reported that they were not healthy. Furthermore, 32.0% of college women had experience to control their weight and 39.8% reported that they exercised to control their weight. There were no significant differences in the height and weight of the subjects according to residential type, but the amount of skeletal muscles mass ($21.0\;{\pm}\;2.6\;kg$) of the subjects that lived in dormitory or boarding home was significantly higher (p < 0.05) than that of women who lived at home. Additionally, 30.8% of students that lived in private residences, 25.0% of students that dwelled in dormitory or boarding homes and 27.7% of students that boarding home w/o food had three regular meals every day (p < 0.05). It has been reported that 18.3% of college students eat processed and instant foods due to their convenience. In the present study, intakes of energy, protein, fat, vitamin A, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, niacin, vitamin C, vitamin E and folic acid for the subjects who lived in dormitory or boarding homes was significantly higher than those of students who lived in private residences (p < 0.05). Additionally, intakes of iron, calcium, and zinc were lower in the subjects that boarding home w/o food (p < 0.05). Finally, the blood glucose level was $84.7\;{\pm}\;13.0\;mg/dL$, and differed significantly by residential types (p < 0.05); however, the average glucose levels of all subjects were within the normal range (90-110 mg/dL).
Background: Research indicates that oxidative stress induced by smoking plays a role in breast cancer. In view of these reports, we aimed to study th relationship between smoking and oxidative stress in breast cancer patients from the western region of Nepal. Materials and Methods: The study included a control group of 42 females (non-smoking healthy women) and a test group sudivided into Group I consisting of 46 female breast cancer patients who were smokers and Group II consisting of 42 non-smoking breast cancer patients. Detailed history of the patients was collected with the help of pre-test proforma. Plasma levels of malondialdehyde (MDA), total antioxidant activity (TAA) which represents total dietary antioxidants, vitamin C and ${\alpha}$- tocopherol were estimated by standard methods. Statistical analysis was done using SPSS version 16. Results: The plasma MDA, TAA, vitamin C and ${\alpha}$- tocopherol were $1{\pm}1.4nmol/ml$, $918{\pm}207{\mu}mol/L$, $1{\pm}0.24mg/dL$ and $0.94{\pm}0.31mg/dL$ in controls, $5{\pm}1.2nmol/ml$, $458{\pm}166{\mu}mol/L$, $0.64{\pm}0.32mg/dL$ and $0.5{\pm}0.3mg/dL$ in Group-I and $2.56{\pm}1.2nmol/ml$, $663{\pm}178{\mu}mol/L$, $0.78{\pm}0.2mg/dL$ and $0.77{\pm}0.2mg/dL$ in Group- II, respectively. Vitamin C, ${\alpha}$- tocopherol and TAA (p=0.001) were significantly reduced whereas MDA (p=0.001) was significantly raised in Group-I when compared to controls and Group-II. Conclusions: We observed a significant rise in oxidative stress and low levels of antioxidants in breast cancer patients with smoking habit. It is well known that free radicals facilitate the progression of breast cancer, possibly increasing the risk of progression to the next stage.
Purpose: The aim of this study was to determine the relationship between serum concentrations of 25-hydroxyvitamin D [25(OH)D] and chronic obstructive pulmonary disease (COPD) prevalence. Methods: The analysis was performed using data from the Fifth Korean National Health and Nutrition Examination Survey, a cross-sectional survey of the Korean civilian population conducted from 2010 to 2012. The analyses were restricted to males who were 40 years of age and above. Complex sample multiple logistic regression analyses were used to examine the associations of COPD prevalence with 25(OH)D and other factors. Results: $FEV_1/FEV_6$ varied significantly with smoking status, age, household income, education level, occupation, body mass index (BMI), and physical activity (p < 0.05). In univariate analysis, smoking status, BMI, household income, education level, and occupation showed association with COPD (p < 0.05), but vitamin D was not associated with COPD (p = 0.078). However, when adjusted with smoking status, household income, education level, occupation, BMI, age, and smoking index, the lowest quartile of 25(OH)D showed OR 1.643 (95% CI 1.161-2.236) compared to 3rd quartile (p = 0.024). Conclusion: A significant relationship was observed between serum concentration of 25(OH)D and COPD.

The present study was designed to analyze the relationship of dietary behavior change and nutrient intake status owing to a depression degree for 143 people over 65 years old living in Echeong and Hansan islands area, South Korea. The depression degree was classified into non depression, minor depression and depressive disorder groups using. The Center for Epidemiological Studies-Depression (CES-D) scale for 143 subjects. The results are as follows; the depression degree significantly made differences according to sex (p<.001), marital status (p<.05), self-related economic status (p<.001) and living expenses (p<.05). The stage of dietary behavior according to the depression degree was as follows; the non depression group was 57.6%, the minor group was 46.8% and the depressive disorder group was 27.1% of the subjects. The intake frequency of the cereal group (p<.05) and fruit group (p<.01) was significantly different among food group intake status owing to the depression degree. Mean adequacy ratio(MAR)[13], MAR[10], and MAR[4] of the depressive disorder group were significantly lower than that of the non depression and minor depression groups. Each average of MAR[13], MAR[10], and MAR[4] for the subjects were $0.68{\pm}0.2$, $0.67{\pm}0.2$, and $0.55{\pm}0.2$. Concerned about the nutrients over 1.0 index of nutritional quality(INQ) 8 nutrients of protein, Phosphorous, iron, zinc, vitamin A, vitamin $B_6$, niacin and vitamin C belonged to the non depression group. Additionally, 6 nutrients of protein, Phosphorous, iron, zinc, vitamin $B_6$ and niacin were included for minor depression and depressive disorder groups.
This study investigated the relationship of Helicobacter pylori (H. pylori) infection to iron-deficiency anemia in high school girls. Four hundred and fourty-five subjects resided in Ulsan City in Korea were evaluated by questionnaire or blood analysis for serum indicators of iron status, daily nutrient intakes, symptoms of anemia, and H. pylori IgG antibody status. In H. pylori infected subjects, total energy intake of was 1534.14±350.81 kcal (73.0% of the Korean RDA), the iron intake of subjects was 11.38±3.90 mg (71.1% of Korean RDA) and calcium intake was 467.63±175.96 mg (58.3% of the Korean RDA). Carbohydrate (p < 0.05), vitamin A (p < 0.05), vitamin C (p < 0.01) intakes were significantly lower in infected subjects than in non-infected subjects. The prevalence of anemia (hemoglobin (Hb) < 12 g/dL.) in H. pylori infected subjects was 22.7% as compared to 14.7% in non-infected subjects. The mean serum ferritin of infected subjects (21.71±21.50 ng/mL) was significantly lower than in non-infected subjects (p < 0.05) (as was the mean Hb concentration (12.54±1.51 g/dL) and hematocrit (37.99±3.64%)). Total iron binding capacity (TIBC) of H. pylori infected subjects (449.09±78.23 ㎍/dL) was significantly higher than that of non-infected subjects (432.99+76.15 ㎍/dL) (P < 0.05). The levels of iron, red blood cell (RBC) and transferrin saturation were similar in infected and non-infected subjects. Two symptoms of anemia, 'pale face (p < 0.01)' and 'decreased ability to concentrate (p < 0.005)', were significantly higher in H. pylori infected subjects than in non-infected subjects. High school girls are known to be more vulnerable to iron deficiency than other age groups, and this research demonstrates that infection with H. pylori increases their risk of iron-deficiency anemia.

This study was conducted to provide basic data for prevention of osteoporosis by examining the factors affecting bone mineral density in pregnant mothers. This investigation was a descriptive research study that analyzed a total of 137 medical records. Differences in T-score between general and obstetric characteristics were assessed by independent t-tests and one way ANOVA followed by Scheffe's post-hoc test. The mean age of the subjects was 32.4 years and the mean T-score was 0.34. The BMI measured at 4 weeks after delivery was significantly higher in the underweight group than in the normal group and the overweight group (F=11.935, p<.001). The BMD was significantly higher in subjects with sufficient vitamin D than in subjects with insufficient vitamin D, in subjects with insufficient vitamin D than in subjects with deficiency vitamin D (F=4.906, P=0.009). BMD was significantly higher in cases without experience of abortion than those with more than one experience of abortion (t=4.264, p<.001), and the normal delivery was significantly higher than that of cesarean section (t= 2.019, p=.046). Based on the results of this study, it is necessary to actively prevent the factors affecting BMD during pregnancy and delivery. The findings presented herein can be used as basic data for the management of osteoporosis.
