This descriptive study aimed to identify the menstrual cycle characteristics and premenstrual syndrome (PMS) prevalence in Korean young adult women using the retrospective and prospective Daily Record of Severity of Problems (DRSP).

In the first stage, participants included 151 nursing students studying in a university located in Seoul. Data were collected from April 20 to June 2, 2017, using the questionnaire on menstrual characteristics, pictorial blood assessment chart, and retrospective DRSP. In the second stage, participants included 17 students with PMS, based on the screening conducted in the first stage. Data were collected using the prospective DRSP from May 29 to 2 September 2, 2017.

Of the study sample, 104 participants (68.9%) had regular periods. Those with regular periods had 11.97 periods annually with a menstrual cycle of 29.38 days and a period duration of 5.72 days. Fifty-five participants (37.4%) showed menorrhagia. Sixty-four participants (42.4%) were found to have PMS based on their retrospective DRSP. When the ratio of women (52.9%) with PMS shown in the prospective DRSP was used as a positive predictive value, the estimated PMS prevalence was 22.4%.

This study provides clinically significant PMS prevalence among Korean young adult women, positive predictive value of the retrospective DRSP, and valid data to basically understand the menstrual cycle characteristics experienced by these women.

The purpose of this study was to compare metabolic syndrome (MS) risk factor prevalence by obesity and age in middle-aged women.

Two hundred and fifty-one subjects were recruited from the health promotion center of a tertiary care hospital in an urban city. MS was defined by the third report of the national cholesterol education program (NCEP) expert panel on detection, evaluation, and treatment of high blood cholesterol in adults(Adult Treatment Panel III)(ATPIII), and obesity was determined by body mass index(BMI)≥ or = 25kg/m².

The mean blood pressure, fasting glucose, total cholesterol, and triglyceride were significantly higher in the obese group than in the non-obese group. The prevalence of MS, hypertension, and impaired fasting glucose were significantly higher in the obese group than in the non-obese group. In the forties, blood pressure was significantly higher in the obese group than in the non-obese group. In the fifties, body fat, systolic blood pressure, fasting glucose, total cholesterol, and triglyceride were significantly higher in the obese group than in the non-obese group.

These results show that the nurse should focus on the obese fifty year old female patients for improvement of the MS risk factors.

This study was aimed at providing basic data for developing a nursing intervention program which enables systematic and correct visual acuity care by discovering out visual acuity conditions, prevalence rate of myopia, and the factors related to myopia with Preschool children.

The subjects of this study consisted of 519 children between 3 and 6 years of age from 12 kindergartens in Seoul which were selected through multiple cluster sampling. Myopia was defined as the spherical equivalent (SE) of more than -0.5 diopters (D) inthe right eye. The data was analyzed by t-test, 2-test, ANOVA, and logistic regression by using the SAS program.

The prevalence rate of myopia was 8.7%. the odds ratio of child myopia when one parent had myopia was 2.2 times higher than when neither parent had myopia. The odds ratio of child myopia when reading more than three books per week was 0.27 times higher than reading less than three books.

Myopia should be continuously and intensively managed from the age of 3

The aim of the study was to assess and identify gender differences in factors associated with prevalence, awareness, and treatment of osteoporosis.

Data for 3,071 men and 3,635 women (age≥ 50) from the Korea National Health and Nutrition Examination Survey 2008~2011 were included. Osteoporosis was defined by World Health Organization T-score criteria. Impact factors and odds ratios were analysed by gender using multivariate logistic regression.

Osteoporosis prevalence rates were 7.0% in men and 40.1% in women. Osteopenia rates were 45.5% and 46.0% respectively. Among respondents with osteoporosis, 7.6% men and 37.8% women were aware of their diagnosis. Also 5.7% men with osteoporosis and 22.8% women were treated. Higher prevalence was found among respondents who were older, at lower socioeconomic levels, with lower body mass index and shorter height in both genders, and among women with fracture history, and non-hormonal replacement therapy. Awareness and treatment rates for the risk groups were similar compared to the low risk controls for both genders. Fracture history increased awareness and treatment rates independently for both genders. Women with perceived poor health status and health screening had increased awareness and treatment rates, but not men.

Results indicate that postmenopausal women have a higher prevalence of osteoporosis than men and awareness and treatment rates were higher than for men. Despite gender difference in prevalence, osteoporosis was underdiagnosed and undertreated for both genders. Specialized public education and routine health screenings according to gender could be effective strategies to increase osteoporosis awareness and treatment.

This study was conducted to examine the prevalence of successful aging and factors influencing successful aging.

This was a secondary analysis study. Data were analyzed from 10,462 elderly people who participated in the 2011 National Elderly Survey. According to the use of community senior facilities, participants were divided into 4 groups: those who used senior centers (group A, n=580), village senior clubs (group B, n=3,240), both of the 2 facilities (group C, n=339), and neither of the 2 facilities (group D, n=6,303). Cross-tabulation and logistic regression were performed.

The prevalence of successful aging was highest in group C (20.94%) and lowest in group D (10.41%). The physical & mental function and active engagement domains were highest in group C, while they were lowest in group D. The disease & risk factors domain were highest in group A, while lowest in group B. An educational level of middleschool or higher and income level in the third or higher quintile were significant factors for predicting successful aging in all groups.

These results provide a basis for designing prevention and management programs as interventions to increase the prevalence of successful aging in Korean older adults.

The objective of this study was to provide a trend analysis of the prevalence of diabetes relative to the socioeconomic, lifestyle, and physiologic risk factors among Korean adults aged over 30 years for a 10-year period using data from the Korean National Health and Nutrition Examination Survey.

Prevalence difference and the slope index of inequality were calculated for each risk factors using binomial regression by considering the repeated cross-sectional features of the data. The prevalence ratio and the relative index of inequality were calculated using log-binomial regression. Linear trend tests were performed using SAS 9.2.

Crude prevalence of diabetes increased over the 10-year period, and was higher for men than for women. It was very high for adults 60 years or over, consistently increasing over time. The prevalence among unemployed men, women with higher level of stress, women with hypertension, and adults with serum triglyceride levels over 135 mg/dL increased over the 10-year period in comparison with the respective control group.

Considering the rapid economic development and associated lifestyle changes in Korea, action should be taken to control the prevalence of diabetes by both preventing and consistently monitoring these identified risk factors using a public-health approach.

The purpose of this study was to verify prevalence rates of atopic dermatitis (AD) in middle school students in Korea and to define AD and associated factors.

This study was conducted using secondary analysis of raw data from the ‘The 6th Korean National Adolescent Health Behavior Survey, 2010’ conducted by the Korea Centers for Disease Control. The participants were 37,570 students. General characteristics and health behavior-related characteristics were analyzed using descriptive statistics, χ²-test and logistic regression analysis.

Results are as follows. 1. There were 8,494 middle school students (22.6%), who had been diagnosed with AD during the last 12 months. 2. Factors associated with AD in middle school students were gender (p< .001), grade level (p= .001), father’s education (p< .001), mother’s education (p= .032), regular dietary habits (breakfasts, p= .025; lunches; p= .003), stress (p< .001), recognition of subjective awareness of one’s health conditions (p< .001), hand washing before meals at school (p= .013), and cessation education for both smoking (p= .002) and alcohol (p= .031).

Results of the study indicate that in order to alleviate AD symptoms in these students, there is a need to develop nursing interventions and education programs taking into consideration these variables and verifying the effects of interventions and programs.

This study seeks to examine prevalence, risk factors, and quality of life of Korean adults with Chronic Obstructive Pulmonary Disease (COPD).

From the database of the Fourth Korean National Health and Nutrition Examination Survey (KNHANES IV-1, 2008), the researchers selected 1,458 adults over the age of 45. The original study was a population-based epidemiological survey of health and nutrition with a stratified multistage clustered probability design. Prevalence of COPD was computed on the basis of the sampling weight. Data were analyzed using descriptive statistics, χ² test, t-test and multiple logistic regression with the SPSS WIN 18.0 and SAS Ver. 9.1 program.

The prevalence of COPD was 18.0% among people older than 45 yr. The prevalence of current smokers was 19.7% in this population and 26.3% in individuals with COPD. Age, gender, education, and smoking levels were found to be risk factors for COPD. Significant difference in quality of life was founded between adults with COPD and the healthy controls.

The results of this study indicate that COPD is a highly prevalent disease in Korea. To reduce the prevalence of COPD and improve health-related quality of life in patients with COPD, nursing interventions must focus on prevention of risk factors.

The goal of this study was to evaluate the impact of life style characteristics on the prevalence risk of metabolic syndrome (MS).

A total of 581 adults were recruited from a cardiovascular outpatient clinic. A newly developed comprehensive life style evaluation tool for MS patients was used, and patient data related to the MS diagnosis were reviewed from the hospital records.

The overall prevalence of MS was 53.2%, and the mean of MS score was 2.6 for patients at a cardiovascular outpatient clinic (78% of the patients had hypertension). Dietary habits among the life style characteristics had significant influence on the prevalence risk of MS and MS scores. And also interestingly, the classification and regression tree (CART) model suggested that the high prevalence risk groups for MS were older adults (61.5≤age<79.4), and adults between 48.5 and 61.5 yr of age with bad dietary habits.

This study indicates that nurses should focus on dietary habits of patients (especially patients classified as high prevalence risk for MS) for improvement and prevention of MS prevalence risk.

The aim of this study was to estimate the prevalence of urinary incontinence among nursing home residents and to identify the factors associated with this condition.

The data were collected from 618 subjects (146 males and 472 females; mean age 79.9±8.4 yr; range 65-102 yr) of 30 nursing homes in Seoul, Gyeonggi-do and Gangwon-do in this cross-sectional study. The data were analyzed by chi-square test, t-test, and multiple logistic regression by using the SPSS/PC ver 12.0 program.

The prevalence of UI was 64.7% (64.6% in women; 65.1% in men). After adjustment for each of the variables considered in this study, six potential factors were strongly associated with UI: activities of daily living, comorbidity, age, cognition, specialty of the facility, and a bladder training program.

Our finding suggests that it is necessary to develop a program for promotion of activities of daily living and to provide a bladder training program to prevent urinary incontinence among nursing home residents.

The purpose of this study was to investigate the effects of the professional nurse's postpartum breast-feeding support on breast-feeding prevalence for mothers who delivered in Baby-Friendly Hospitals (BFH).

This quasi experimental study was designed with a nonequivalent control group post test. The subjects of this study were 55 mothers who were hospitalized in the delivery room of a university hospital which was selected as a BFH in Daegu from October 1, 2005 to June 30, 2006. Twenty nine mothers were assigned to the experimental group and 26 mothers to the control group. Postpartum breast-feeding support by nurses' telephone calls to the experimental group was provided once a week for 4 weeks postpartum and then once a month for 16 weeks postpartum. Four post tests were given at postpartum week 4, 8, 12, and 16. The control group was given a telephone call at postpartum week 4, 8, 12, and 16.

The breast-feeding prevalence of the experimental group was significantly higher than that of the control group for each period.

Postpartum breast-feeding support by nurses may be a useful intervention to increase breast-feeding prevalence.
