Prevalence, awareness, treatment, control and risk factors of hypertension in Korea: the Ansan study

Objectives To determine prevalence, awareness, treatment, and control of hypertension, and its risk factors in an urban Korean population. Design and setting A cross-sectional survey in Ansan-city, Korea. Subjects and methods Population-based samples of people aged 18–92 years in Ansan-city, Korea, were selected, yielding 2278 men and 1948 women, and their blood pressures were measured using a highly standardized protocol. Hypertension was defined as a systolic BP ⩾ 140 mmHg or diastolic BP ⩾ 90 mmHg or reported treatment with antihypertensive medications, and subclassified according to 1999 WHO-ISH guidelines. Isolated systolic hypertension (ISH) defined as a systolic BP ⩾140 mmHg and diastolic BP < 90 mmHg was also examined. Data were stratified by age and sex. Results The overall prevalence of hypertension in this study was 33.7%. Among these, 64.9% had Grade 1 hypertension, 22.5% Grade 2, and 12.5% Grade 3. Age-specific prevalence of hypertension increased progressively with age, from 14.19% in 18 to 24 year-olds to 71.39% in those 75 years or older. Hypertension prevalence was significantly higher in men (41.5%) than in women (24.5%) (P < 0.001). Isolated systolic hypertension had significantly lower prevalence (4.33%) within the population, although in the elderly aged 55 years or more it rose by 11.13%. Overall, 24.6% of hypertensive individuals were aware that they had high blood pressure, as much as 78.6% were being treated with antihypertensive medications, and 24.3% were under control. Hypertension awareness as well as treatment and control rates varied by sex, with women higher in all three rates. Multivariate analysis revealed that age, body mass index and abdomen circumference were significantly associated with prevalence of hypertension both in men and women. Conclusions Hypertension is highly prevalent in Korea. Despite the high rate of treatment, the rates of awareness and control are relatively low, suggesting the nationwide demand for preventing and controlling high blood pressure in Korea in order to avert an epidemic of cardiovascular disease.

Secular trend in age at menarche for South Korean women born between 1920 and 1986: the Ansan Study

BACKGROUND There is strong evidence of a downward secular trend in age at menarche in Europe and the USA during the last century and in Japan and China during the past few decades. However, no study on this trend in age at menarche has been reported in South Korea. AIM To measure the trend in age at menarche in South Korea during the past few decades and the association of height with this trend. SUBJECTS AND METHODS A total of 1061 South Korean women born between 1920 and 1986 were randomly recruited from Ansan Cohort Study samples and separate school girl samples, and subjected to this analysis. The data on age at menarche were collected by the retrospective method. Height was measured at time studied and assumed to be relatively constant since age at menarche. Women were grouped with respect to decade of birth and mean age at menarche was determined. The secular trends in annual age at menarche and in height were analysed by the 3-year moving average. RESULTS Mean menarcheal age decreased from 16.8 to 12.7 years during the past 67 years, corresponding to -0.64 years per decade. Height increased from 149.23 to 161.75 cm during the same period, showing an inverse relationship in the change of trend between height and mean age at menarche. CONCLUSION Our data suggest that the downward secular trend in age at menarche may reflect the secular change in physical growth in South Korean women during the past 67 years.

[A study on physical symptom, activity of daily living, and health-related quality of life (HRQoL) in the community-dwelling older adults].

PURPOSE This study aimed to identify the relationships among physical symptoms, activities of daily living, and health-related quality of life (HRQoL) in community-dwelling older adults. METHODS A stratified random sampling method was conducted to recruit participants from May 10 to August 17, 2007. Physical symptoms were measured using the Physical Health Questionnaire (PHQ), activities of daily living using the Late-Life Functional and Disability Instrument (LLFDI), and HRQoL using the Medical Outcomes Short-Form Health Survey (SF-36) in 242 community-dwelling elderly Korean people. RESULTS The HRQoL correlates with the physical symptoms (r=-.31) and the function component (r=.59). Of the two disability parts of the LLFDI, the limitation dimension correlates higher (r=.57) with HRQoL than the frequency dimension (r=.42). The HRQoL is significantly associated with the function component, and disability limitation in capability which explained 44.4% of variance in physical health. CONCLUSION These results may contribute to a better understanding of physical symptoms, activities of daily living, and HRQoL in community-dwelling older adults. Therefore, health programs for prompting older adults health should be planned based on results of the study.

The lived experience of Korean immigrant women acculturating into the United States

Immigration to a different country and a new way of life affects immigrants in many different ways. The changes that occur can influence the way they live and think as well as their personal health. This is especially true with Korean women. However, we still do not have sufficient knowledge about how these women adjust to their new environments. The rate of Korean immigration to the United States has gradually increased since 1965. According to Bouvier and Arnold, the Korean immigrant population is estimated to reach 1.3 million in the year 2000. Korea ranks fourth in number of emigrants, closely following the Philippines, China, and Vietnam. Research reveals that approximately 45% of recent emigrants are women, and this percentage is rapidly increasing. Research concerning this populations lives, their process of acculturation, and, above all, their health and well-being is lacking greatly in quantity and quality. This study demonstrates that the change of womens roles, due to their process of acculturation, cannot be considered separate from their well-being. For this study, 6 Korean women immigrants living in New York were chosen to provide information. The participants volunteered under the condition that their privacy and confidentiality would be protected. A pattern of acculturation experience was revealed in four successive, principal stages: dreams, conflicts, renunciation, and remorse. Hopefully, the following descriptive data will provide knowledge for implementing qualitative care requirements for Korean women immigrants in the United States.

The Effect of Hand Acupuncture Therapy and Hand Moxibustion Therapy on Premenstrual Syndrome Among Korean Women

Premenstrual syndrome (PMS) symptoms can reduce quality of life and impair daily functioning. This study examined the effects of Korean hand acupuncture therapy (HAT) and hand moxibustion therapy (HMT) on symptom severity in Korean women with PMS. This quasi-experimental pilot study based on the khi, yin, yang, and the five elements theory used a nonequivalent control group pretest—posttest design. Experimental groups received 10 sessions of either HAT or HMT treatment. Outcome measures included menstrual symptom severity as measured with the Menstrual Symptom Severity List and skin temperature change measured with Digital Infrared Thermographic Imaging. Both experimental groups had significantly reduced overall PMS symptom severity scores following therapy as compared to women in the control group. The HMT but not the HAT group showed improved flow of khi and balanced skin temperature in symmetric body areas. HAT and HMT may be effective strategies for women to reduce PMS symptoms.

Effects of exercise program on physical fitness, depression, and self-efficacy of low-income elderly women in South Korea.

OBJECTIVE This study aimed to examine the effects of exercise programs on physical fitness, depression, and self-efficacy in low-income elderly women (age > or = 75). DESIGN AND SAMPLE A pretest-posttest experimental research design with a control group was used. The sample consisted of 26 women in the exercise group and 22 women in the wait-list control group in Seoul, Korea. MEASURES The measures of physical fitness included body mass index, cardiopulmonary endurance (blood pressure and heart rate), muscle strength (hand grip strength), flexibility (degree of bending of the upper body), and balance (duration of time for which the subject could stand on one foot). Depression and self-efficacy were measured by the Center for Epidemiological Studies Depression scale and a modified form of Lees scale, respectively. All measures were obtained twice: at baseline and at the completion of the exercise program. INTERVENTION The exercise program consisted of 4 weeks of education along with 8 weeks of physical exercise. RESULTS After the intervention, significant improvements were found in depression, self-efficacy, and all measures of physical fitness, except heart rate and flexibility, in the experimental group. CONCLUSION The exercise program may be recommended as a method to maintain and promote the health of low-income elderly women.

Temporal Patterns of Movements in Institutionalized Elderly With Dementia During 12 Consecutive Days of Observation in Seoul, Korea:

Background: The availability of increasingly sophisticated technology has meant that ambulation can be measured with precision over an extended period. Methods: An integrated circuit tag-monitoring system was set up to measure the distance moved in a dementia care unit in Korea in 2006. Various indicators were developed to measure temporal patterns of ambulation over time, such as the median distance moved per hour and the percentage of hours moved. Results: 12 consecutive days of movement data were available for 8 subjects. The mean age of the subjects was 76 ± 5.3 years. The median distance walked per day ranged from 206 to 976 m, and the percentage of hours with movement ranged from 28% to 81%. The changes in the activity level during daytime, evening, and nighttime also differed among the 8 subjects. Discussion: The indicators developed appeared to differentiate temporal patterns of movement in demented persons.

[A study on health concern, self-rated health, health status, and health promotion behavior of elderly women in urban area].

PURPOSE This study was conducted to examine the relationship among health concern, self-rated health, health status, and health promotion behavior of elderly women in urban areas. METHOD The subjects of this study consisted of 271 Korean elderly women over 65 years. The data was collected through personal interviews using questionnaires from March to May of 2003. The data was analyzed by the SPSS (ver.10.0) computer program, and it included descriptive statistics, t-test, one way ANOVA, and the pearson correlation coefficient. RESULT There was a significant positive correlation between self-rated health and health status. Health promotion behavior related to all health concerns, self-rated health, and health status. CONCLUSION This study showed that strategies of elderly care intervention to put in practice health promoting behavior is needed to improve quality of life in elderly women. In addition, health education appropriate for health maintenance and health promotion must be done for daily living to maintain well-being for the rest of their lives.

Testing and Developing the Health Promotion Model in Low-Income, Korean Elderly Women

This study was conducted to test Penders health promotion model in low-income, Korean elderly women. A total of 389 low-income, Korean elderly women completed the interviews focused on the concepts in health promotion model. Seventy-three percent of the variance in health-promoting behaviors was accounted for by prior health-related behavior, biological, psychological, and sociocultural factors, behavior-specific cognitions and affect, environmental influences, commitment to a plan of action, and health-promoting behavior variables in a modified health promotion model. Findings from this study may support the conceptual framework for future nursing practice and research studies in this vulnerable population.

Sex education during the school-aged years influences sexual attitudes and sexual health in college: A comparative study from Korea

Sex education is provided routinely to school-aged children in many countries without enough evidence that it will benefit them when they become adults. The purpose of this study was to examine the long-term influence of the sex education that was provided during the school-aged years on the attitudes, behaviors, and sexual health among male and female college students in Korea. For this descriptive, comparative study, the data were obtained from 3609 male and 2180 female college students by using the proportional quota sampling method. Overall, the female students had more opportunities for sex education. Receiving this education during the school-aged years lowered the sexual double standard score but was not related to sexual activity among the male and female students. Receiving sex education at different time points during the school-aged years had differential influences on the sexual attitudes and indicators of sexual health between the male and the female students. The results of this study suggest extending the role of school nurses to include redesigning the content of sex education programs, based on the sex and age of the students, and using midwives to provide sex education in community settings.Sex education is provided routinely to school-aged children in many countries without enough evidence that it will benefit them when they become adults.
