Purpose: The aims of this study were to evaluate early breast cancer screening rate of occupational health nurses and to analyze factors affecting their behavior. Method: We reviewed and analyzed the structured questionnaires of III respondents from 230 participants in continuing education of occupational health nurses. Result: Breast self examination was performed in 72.1%, clinical breast examination was received in 30.6% and mammography was received in 40.5% significant factors affecting breast self examination were age and the age of menarche. significant factors affecting clinical breast examinations for breast cancers were age and the place of residence, and factors affecting mammography were age, monthly income, alcohol intake, the age of menarche, and attitude about early screening for breast cancers. Conclusion: Early breast cancer screening rate of occupational health nurses was higher than that of general population of women. But the rate of clinical breast examination and mammogaphy were lower of less than 50% of respondents. Therefore occupational health nurses who are responsible for health management of working women need more education for themselves to promote the motivation and to increase the rate of participation in early breast cancer screening.

A total of 216 women of natural menopause over 40 years were interviewed to find the relationships among general environmental fctors, anthropometric measurements, daily nutrient intake, and BMD. The average age of the subjects was 54.0 years. Average ages of menarche and menopause were 16.7 years and 47.7 years, respectively. In general, energy and nutrients intake of the subjects were relatively low compared to the Korean recommended dietary allowances(RDA). Specifically, intakes of energy, protein, clcium, iron, and vitamin A were lower than Korean RDA, BMD levels of lumbar spin (LS), femoral neck(FN), ward's triangle(WT), and trochanter(TC) were significantly decreased wit age in descending order of LS, FN, TC, and WT BMD, accordingly. BMD levels of FN and TC of the subjects were higher compared to those of the same age but BMD levels of LS and WT were lower than those of the same age from the general population. For factors related to BMD levels, hight, weight, BMI, and hip circumference had positive correlations with BMD. On the other hand, menarche, and WHR had negative correlations with BMD. Protein, lipid, iron, vitamin B1, vitamin B2, and niacin intake among factors related nutrient intakes were positively correlated with BMD levels. Based on the stepwise regression analysis, the factors and vitamin B1 intakes. Overall, BMD was decreased with age as can be expected. For those being tall, moderately weighed, and smaller waist circumference, BMD levels were high when the relationships of body characteristics and BMD levels were considered. The higher BMD levels were found for those with high intake of protein and vitamin B1. From the findings, it is suggested that the women after menopause keep the optimum body weight and good eating habits. Specially intakes of good quality protein, vitamin B1 seemed to be important.

Bone mass accretion during puberty appears to be critical in the development of peak bone mass. Although bone density of females in Korea has been studied, only a few studies have related bone mass with anthropometric patterns or puberty in the pubescent girls. This study was conducted as part of a study of major determinants of bone development during puberty. Subjects were aged 14∼16 yr(mean 14.97), and had no history of disorders or dedication use likely to influence bone or calcium metabolism. Bone mineral density and content were measured by dual energy X-ray absorptiometry using a Lunar DPX+Scanner (Lunar Madison, WI). Also, total body fat, and total lean body mass were assessed using a Lunar DPX dual-energy X-ray absorptiometer, Pubertal status was assessed according to the Marshall and Tanner guidelines. Serum levels of osteocalcin was measured by RIA using a commercial kit assay. Skinfold measurements were taken with a skinfold caliper(Lange Caliper, USA). Data were analyzed using the regression and GLM procedure of the statistical package SAS. The results indicated that the observed means for lumbar spine BMD and femoral BMD correspond to approximately 91% and 96% of the means for young adult females, respec tively. All subjects were menarchal, with the majority being in the middle to end stages of pubertal development. Total body BMD was positively related to fat mass(P<0.001), lean body mass and time since menarche, and negatively related to urine pyridinoline, serum alkaline phosphatase and osteocalcin. The data indicate that girls who reported lower age for menarche had significantly higher bone densities than girls who reported higher age for menarche. Attaining peak skeletal bone mass during puberty may reduce the incidence of osteoporosis in later life. this finding suggests that early menarche may augment peak bone mass, influencing the extent of bone loss later in adulthood. The results suggest that good nutrition in childhood appears to be needed not for growth and development, but possibly also to assure an optimal peak of bone mass and thus greater latitude for the maintenance or skeletal integrity in the face of bone losses. Troeps skinfold thickness was a better predictor of total BMD and total BMC than was any other skinfold thickness. The study did not find a relationship between total BMD and body fat %, but total fat was significantly positively related to total BMD(r=0.49) and total BMC(r=0.60). It supports earlier report that there was a significant correlation between TBMD and body weight. Conclusively, total fat, lean body mass and pubertal development could influence BMD in pubescent girls. Clearly, longitudinal studies are required to assess the effect of puberty on peak bone mass, and to define further the potential determinants of peak bone mass.

It is important to identify modifiable risk factors for breast cancer, because the breast cancer is one of the major causs of mortality among women. Some reported that obesity is a risk factor for breast cancer, but the results are not constant. Many risk factors are related to the duration of estrogenic stimulation of the breast. In general, early menarche and late menopause are positive risk factors. Human breast cancer has different characteristics according to the status of menopause(premenopause and postmenopause). In premenopausal women, about 60% of circulating estrogen is from the ovaries in the form of estradiol, and the remaining 40% is estrogen formed primarily in the adipose(fat) tissue via aromatization of androstenedion from the adrenal glands. After menopause this adipose cell production of estrone is the main source of estrogens and the level of estrone is maintained approximately at premenopausal levels. This study was undertaken to determine the role of body size and body mass index by status of menopause in development of breast cancer using retrospective case/control study. From March 1991 to February 1997 at the Wonkwang University Hospital, the breast cancer cases(n=72) and controls(n=86) were selected. By statistical analysis method, regression analysis, paired T-test and multiple logistic regression were done to estimate the influenced factors same as height, weight, BMI, age at menarche and age at menopause. The following results were obtained : 1. In premenopausal women, age at menarche was showed comparatively high correlation coefficients and BMI was described prominently highly in postmenopause. 2. At the results of multiple regression analysis, age at monarch, BMI and weight were showed as significant variables. In this method, critical factor ($R^2$) was 0.054. 3. Paired samples T-test was undertaken to test mean difference between two groups of cases and controls. The result of test performance showed a significant difference. 4. In comparison with women whose weight less than 50 kg, the ORs for the upper 5th group was 1.82(95% confidence interval). The heaviest women had a higher risk(OR=1.14, 95% confidence interval $1.12{\sim}1.31$, p=0.005). Higher body mass index was significantly associated with increased risk of premenopausal breast cancer (OR=1.01, 95% confidence interval $1.08{\sim}l.18$, p=0.05).

Purpose: This study examined the demographic and lifestyle differences between women with osteopenia and those with normal bone mineral density (BMD) to identify risk factors for osteopenia. Method: Participants comprised 381 women age 40-64 years. Data were collected using surveys, BMD measures, and anthropometric parameters. Results: Prevalence of osteopenia was 29.1%; significant differences in age group, job, age at menarche, age at menopause, and body mass index were found between women with osteopenia and those with normal BMD. Logistic regression analysis indicated that advanced age, unemployment, lower body mass index, and lack of exercise in women were significantly associated with osteopenia. Conclusion: This study suggests the need for strategies to improve bone health and continuous cohort studies to identify risk factors.

Objectives: The purpose of this investigation was to examine the association between endometrial cancer and possible etiological agents. Methods: A case-control study was conducted in Iran between March 2012 and May 2016. The demographic and reproductive factors of 205 women with endometrial cancer were compared, and 590 healthy cases were participated in the control group. For each endometrial cancer case, there were three controls, who were matched in terms of age and residence. The data were considered significant at $p{\leq}0.05$. Results: After adjusting the variables, the nulliparity (OR 6.23, 95% CI 2.86-13.59), the nulligravidity (OR 5.94, 95% CI 2.51-14.06), the positive family history of reproductive cancer (OR 4.97, 95% CI 2.33-10.59), the infertility history (OR 2.38, 95%CI 1.32-4.31), the obesity ($BMI{\geq}25$) (OR 1.71, 95% CI 1.16-2.52), the early menarche age (<12 years) (OR 2.10, 95% CI 1.17-3.75), and the hormonal contraception use (OR 1.69, 95% CI 1.15-2.49) were found to be associated with an increased risk of endometrial cancer. Nevertheless, the education level, the job of women, the marital age, the leisure activities, and the breast feeding were not found to be associated with the endometrial cancer after adjusting the variables. Conclusion: Scheduling of the screening program is vitally indispensable to identify endometrial cancer in women with nulliparity, nulligravidity and the positive family history of cancer. In addition, women with early menarche, those with the history of infertility, the obese ones, and those who use contraception pills need to be particularly aware of the potential risks.

This study was attempted to investigate the prevalence of anemia and to obtain nutritional education data for high school girls by analyzing the factors influencing on anemia. Total fo 113 subjects(21 female high school students in Seoul and 92 female students in Inchon) were participated in this study from July 1 to July 15, 1990. Hb and Hct values were measured to evaluate the iron status. Duncan's multiple range test were performed for the comparison between the mean values of the various group. Correlations among various factors were analyzed by Pearson's correlation coefficient. The results of this study are summarized as follows. 1. The maen Hb and Hct values were 13.2g/dl and 41.3%. The rate of anemia of the subjects was 5.3% by the criteria of Hb concentration and 2.7% by the Hct value according to World Health Organization. 2. Subjects who had an early menarche had significantly higher weight and triceps than the ones ofr the girls with a late menarche. 3. There were positive relationships among Hb and Hct values, ages of memarche and cycle of menstruation. Hb, Hct values were significantly higher in the subjects who had frequent bed time snack, high intakes of meats and fishes group and vitamin A, and low calcium intake. In conculsion, the prevalence of anemia of the subjects was much lower than the previous years. There were positive relationships among Hb and Hct values, age of menarche, night snack, and intakes of meats and fishes and fruits. Therefore, it could be concluded that nutrition education should be emphasized for the high school girls to improve the quality of diet and prevent anemia.

Objectives : This study was performed to evaluate the reproducibility of a questionnaire concerned with reproductive history and to ascertain which characteristics of the subjects (age, the visit-revisit intervals, education and chronic disease) are associated with good reliability in the Korean Multi-Center Cancer Cohort (KMCC) study. Materials and Methods: A total of 19,688 participants were enrolled between 1993 and 2004. Among them, we selected 386 participants who were aged 40 or more and who re-visited within 8 years after the first visit. Reliability was measured by the percent agreement according to error range for the continuous variables and the percent agreement and kappa statistics for the categorical variables. Results : The pregnancy histories were reliable (kappa=0.67) and the reasons for being menopausal among the postmenopausal women were also reliable (kappa=0.92). The percent agreement of the breast-feeding history was high (96.1%), although the kappa statistic was low. For the continuous variables, when the error range of one variable was considered to be reliable, the percent agreement of the age at menarche and the age at the first full term pregnancy was good (69.4% and 83.6%), whereas that of the age at menopause was low (51.5%). The factors associated with high reliability were a younger age, the presence of chronic disease and a short visit-revisit time interval. Conclusions : The agreements for parity, the reasons for menopause, and the breastfeeding history in the reproductive history questionnaire used in the KMCC were relatively good. The questionnaire for the menarche age and the menopausal age might have lower reliability due to the difference between Korean age and American age. To obtain reliable information, more attention should be given to the items in questionnaire-based surveys, and especially for surveying old-aged women.

The age of puberty represents a very critical time in the life history of every young woman. The menarche stands as primary indicator of the onset of sexual maturation in females. By late adolescence, 75% of girls experience some problem associated with menstruation. Delayed, irregular, painful, and heavy menstrual bleeding are leading reasons for physician office visits by adolescents, and dysmenorrhea is the leading reason for school absenteeism among girls. This article discusses normal menstrual function during adolescence, then reviews the clinical presentation, evaluation, and management of adolescent dysmenorrhea, dysfunctional uterine bleeding, amenorrhea, and polycystic ovary syndrome.
