Purpose: The purpose of this study was to follow-up the frailty of the old who received home health care by Registered Nurse in Public Health Center over 8 years. Methods: We used the second wave data which was a comprehensive longitudinal data set, Public Health Information System of a public health center located in Seoul from 2010 to 2018. For statistical analysis, a mixed model of repeated measures by R program was used. Results: Frailty (range: 0~31) was getting worse significantly from 5.38 on registration to 6.54 on 4th year, 7.40 on 7th year, 7.69 on 8th year with adjustment for age, sex, economic status, the number of family, and the number diseases. The coefficient of parameters with frailty change was serviced year (β=0.29, p<.001), age (70~79 to 60~69; β=0.98, p=.018) and sex (female to male; β=2.55, p<.001). Conclusion: This study showed that the home visiting health service needs to take attention to aged 70s and over, female. The home health care of public health center need to be extended more practical and effective services in terms of 'community care'and 'ageing in place'.

The purpose of this study is to examine the longitudinal causal relationships between maternal parenting stress and parenting attitudes. Relevant data from mothers with infants aged from 2 to 4 years of age was gathered from the Panel Study of Korean Children were analyzed by means of Latent Growth Modeling. The findings are as follows, First, levels of parenting stress increased whereas the extent of positive parenting attitudes decreased as children grow older. Second, the initial value of parenting stress was observed to have a negative effect on the initial value of positive parenting attitudes. Third, those mothers who generally have faster speeds of increasing parenting stress tend to have faster speeds of decreases in positive parenting attitudes. What this study clearly revealed is that the positive parenting attitudes of mothers with infants tend to improve when the mothers try to efficiently deal with their parenting stress by either acquiring appropriate parenting knowledge or receiving support from their families and communities.

For the assessment of representative and longitudinal Zn nutriture in South Koreans, Zn, phytate and Ca intakes were determined using four consecutive years of food consumption data taken from Korean National Nutrition Survey Report (KNNSR) every 10 years during 1969-1998. The nutrient intake data are presented for large city and rural areas. Zn intake of South Koreans in both large city and rural areas was low during 1969-1988 having values between 4.5-5.6 mg/d, after then increased to 7.4 (91% Estimated Average Requirements for Koreans, EAR = 8.1 mg/d) and 6.7 mg/d (74% EAR) in 1998 in large city and rural areas, respectively. In 1968, Zn intake was unexpectedly higher in rural areas due to higher grain consumption, but since then until 1988 Zn intake was decreased and increased back in 1998. Food sources for Zn have shifted from plants to a variety of animal products. Phytate intake of South Koreans during 1969-1978 was high mainly due to the consumption of grains and soy products which are major phytate sources, but decreased in 1998. The molar ratios of phytate:Zn and millimmolar ratio of phytate${\times}$Ca:Zn were decreased due to the decreased phytate intake in South Koreans, which implies higher zinc bioavailability. The study results suggest that Zn nutriture has improved by increased dietary Zn intakes and the decreased molar ratio of phytate:Zn in South Koreans in both large city and rural areas.

Background: Bronchial hyperresponsiveness (BHR), an important physiological feature of asthma, is a prognostic marker of childhood asthma. Purpose: We aimed to investigate the factors associated with BHR in adolescents with childhood asthma. Methods: Two hundred and fifteen adolescents (≥13 years of age; 149 males, 66 females) who were diagnosed with asthma during childhood were enrolled, underwent methacholine challenge tests, and were divided into the BHR group (<25 mg/mL of provocation concentration causing a 20% fall in forced expiratory volume in 1 second [FEV₁] [PC₂₀], n=113) or non-BHR group (≥25 mg/mL of PC₂₀, n=102). We examined longitudinal changes in BHR and the risk factors for its persistence in the 108 adolescents for whom baseline data, including methacholine PC₂₀ at age 6 years, were available. Multivariate logistic regression analyses were performed to assess the factors associated with BHR in adolescents. Results: Mold sensitization (adjusted odds ratio [aOR], 5.569; P=0.005) and increased blood eosinophil count (aOR, 1.002; P=0.026) were independently associated with BHR in boys but not girls. The odds of BHR decreased by 32% with each 1-year increase in age in boys (aOR, 0.683; P=0.010) but not girls. A reduced FEV₁/forced vital capacity ratio (<90%) was independently related with BHR in female patients only (aOR, 7.500; P=0.007). BHR decreased with age throughout childhood. A low methacholine PC₂₀ at age 6 years was independently associated with persistent BHR throughout childhood in male and female patients, whereas early mold sensitization was a risk factor for persistent BHR in male patients only (aOR, 7.718; P=0.028). Conclusion: Our study revealed sex-specific differences in the factors associated with BHR in adolescents with childhood asthma. Our findings suggest the risk factors that might affect asthma transition from childhood to adolescence and adulthood.

Objectives: We aimed to estimate the space-time distribution of the risk of suicide mortality in Iran from 2006 to 2016. Methods: In this repeated cross-sectional study, the age-standardized risk of suicide mortality from 2006 to 2016 was determined. To estimate the cumulative and temporal risk, the Besag, York, and Mollié and Bernardinelli models were used. Results: The relative risk of suicide mortality was greater than 1 in 43.0% of Iran's provinces (posterior probability >0.8; range, 0.46 to 3.93). The spatio-temporal model indicated a high risk of suicide in 36.7% of Iran's provinces. In addition, significant upward temporal trends in suicide risk were observed in the provinces of Tehran, Fars, Kermanshah, and Gilan. A significantly decreasing pattern of risk was observed for men (β, -0.013; 95% credible interval [CrI], -0.010 to -0.007), and a stable pattern of risk was observed for women (β, -0.001; 95% CrI, -0.010 to 0.007). A decreasing pattern of suicide risk was observed for those aged 15-29 years (β, -0.006; 95% CrI, -0.010 to -0.0001) and 30-49 years (β, -0.001; 95% CrI, -0.018 to -0.002). The risk was stable for those aged >50 years. Conclusions: The highest risk of suicide mortality was observed in Iran's northwestern provinces and among Kurdish women. Although a low risk of suicide mortality was observed in the provinces of Tehran, Fars, and Gilan, the risk in these provinces is increasing rapidly compared to other regions.

Objectives : This study investigated poor self-rated health and its associated factors in married Korean women, focusing on the burdens related to family affairs and social support. Methods : Cross-sectional data from 3,039 married women (between 25 and 64 years old) who completed Korean Longitudinal surveys of Women and Families were analyzed. Results : Among working women, only two factors-lack of husband's involvement in housework and insufficient communication with husband - influenced poor self-rated health. Among housewives, lack of husband's involvement in housework, insufficient communication with husband, low satisfaction of marriage, and avoidance of alcohol consumption were associated with poor self-rated health. Conclusions : Regardless of whether women are employed or housewives, husband's support is a very important factor affecting women's health. Social efforts for changing perceptions and values are needed so that men and women mutually support each other in family affairs.

본 연구에서는 12개년의 종단면 시계열 자료를 활용하여 절대소득과 상대소득을 포함한 노후의 소득수준이 생활만족도에 영향을 미치는지의 여부를 검증하였다. 연구결과, 자산분위별, 지역별 및 학력기준에 따른 각 준거집단의 상대소득이 노인 자신의 절대소득보다 노후의 생활만족도에 더 큰 영향력을 미치고 있음을 확인할 수 있었다. 횡단자료를 이용한 상관관계 분석에서도 상대소득은 생활만족도와 밀접한 관련성을 갖는 것으로 나타났으며 종단자료를 이용한 패널분석모형에서 준거집단의 상대소득 수준은 노후의 생활만족도 수준결정에 있어 유의미한 영향을 보이고 있었다. 비교대상이 되는 준거집단의 소득수준보다 상대적으로 자신의 소득수준이 높을 경우에 노후의 삶의 만족도는 증가하는 것으로 확인되었다. 또한 과거 시점의 생활만족도 수준도 현재 노인의 평균 생활만족도 결정에 유의미한 영향을 미치는 것으로 나타났다. 종단자료 분석에서 나타난 이러한 분석결과는 중장기적 관점에서의 노인의 생활만족도 결정과정에서 기존의 절대소득가설보다는 상대소득가설이 보다 타당하다는 사실을 입증하고 있다. 구체적인 학문적 및 실천적 함의로는 정책당국의 경제적 지원만으로는 충분치 않으며 노인일자리를 창출·보급함으로써 노인들의 사회참여 기회를 제공하는 것이 필요하며, 다양한 형태의 비경제적 사회참여 확대 및 이를 보장하기 위한 체계적인 노력이 뒷받침되어야 할 것으로 판단된다.
