Early age at menarche, which is indicator of early biological maturity, has been shown to be associated with increased adult body mass index. Early menarche has also been associated with many cardiovascular disease risk factors and metabolic syndrome. To evaluate the impact of menarche to cardiovascular risk factor, we assessed by age at menarche, brachial-ankle pulse wave velocity (baPWV), which represents arterial stiffness, in women with or without metabolic syndrome. The subjects recruited for this study were three hundred one women. Relatively early menarche and relatively late menarche were classified according to less than $50^{th}$ percentile for relatively early menarche, and great than the $50^{th}$ percentile for relatively late menarche. Subject were divided four group, 1) women who had not adulthood metabolic syndrome and relatively early menarche, 2) women who had not adulthood metabolic syndrome and relatively late menarche, 3) women who had adulthood metabolic syndrome and relatively early menarche, 4) women who had adulthood metabolic syndrome and relatively late menarche. Women who had a relatively early menarche with adulthood metabolic syndrome had significantly high levels of blood pressure, triglyceride, fasting insulin and homeostatic model assessment of insulin resistance (HOMA-IR) levels than women with late menarche with adulthood metabolic syndrome, and had significantly lower HDL-cholesterol levels. And also, women who underwent a relatively early menarche with metabolic syndrome had highest level of baPWV in adult. In this study we found effect of age at menarche on adulthood metabolic risk factors for cardiovascular disease (e.g., baPWV, insulin resistance, hyperlipidemia) in Korean women.

The purpose of this study was to examine the degree of depression in housewives and to analyze the effects of psychosocial factors on the depression. Especially the focus was on the differences in the degree of depression and the influencing factors on depression between those in early adulthood and those in middle adulthood The subjects consisted of 130 early adulthood housewives and 142 middled adulthood housewives. They asked to complete several self-report measures that were used to assess the variables of interest. The result indicated that the depression in housewives were serious enough to arouse social workers' attention. The average housewives were suffered from mild depression, and 17.1% of the housewives were in need of professional treatment. There was no significant difference in the degree of depression between the early adulthood housewives and the middle adulthood housewives. There were, however, differences in the factors which explain and predict the depression between these two groups. The results of step-wise multiple regression analysis indicated that the factors which predict the depression for the early adulthood housewives were self-esteem, conflict with the spouse, experience of painful events, age, and conflict with the children. On the other hand, the factors which predict the depression for the middle adulthood housewives were self-esteem, conflict with the spouse, job, and income. Implications of the findings for social work interventions were discussed.

The mean age at menarche (AAM) of Korean females has been rapidly decreasing over the last 50 years; currently, the prevalence of early menarche (<12 years) is 22.3%. Female adolescents who experience early menarche are known to be at greater risk of psychosocial and behavioral problems along with several physical health problems such as menstrual problems. They also tend to achieve a shorter final height and develop obesity. Population-based Korean studies have shown a strong association between early menarche and the risk of obesity, insulin resistance, metabolic syndrome, nonalcoholic fatty liver disease, diabetes, breast cancer, and cardiovascular disease in adulthood. Although the exact mechanism of how early menarche causes cardiometabolic derangement in later adulthood is unknown, childhood obesity and insulin resistance might be major contributors. Recent studies demonstrated that an excessive consumption of fructose might underlie the development of obesity and insulin resistance along with an earlier AAM. A positive association was observed between sugar-sweetened beverages (a major source of fructose) intake and obesity, metabolic syndrome, insulin resistance, and cardiometabolic risk in Korean females. In pediatrics, establishing risk factors is important in preventing disease in later life. In this regard, early menarche is a simple and good marker for the management of cardiometabolic diseases in adulthood. Decreasing one's fructose intake might prevent early menarche as well as the development of obesity, insulin resistance, and cardiometabolic diseases.

This study is aimed to examine effects of sociodemographic, social relation, and health related factors on risky drinking among early, middle, and older adulthoods. Using the sixth(2013-2016) National Health and Nutrition Examination Survey, separate logistic regression analyses were conducted for women's early adulthood (n=1,143), middle adulthood (n=1,306), and older adulthood (n=875) to test factors associated with risky drinking. For study results, as for women's early adulthood, education, marital status, employment, depressive feeling, and smoking were statistically associated with risky drinking. As for women's middle adulthood, only subjective stress level and smoking were associated with risky drinking. As for women's older adulthood, education, suicidal ideation, and subjective health condition were associated with risky drinking. These results found different factors influenced risky drinking according to life stages. Based on these results, convergent implications about reducing risky drinking according to life stages of women were discussed.

This study examined the applicability of the transtheoretical model(TTM) to understanding exercise behavior of early adulthood. A cross-sectional study was conducted and data wee collected from 1618 adults aged from 20 to 39 through internet survey. Major conclusions wee as follows: 1. Stage distribution for exercise behavior was 15.6%, 26%, 25%, 19%, 14.4% for precentemplation, contemplation, preparation, action, maintenance stages, respectively. 2. Behavioral processes were more frequently utilized than cognitive processes for action and maintenance stage. 3. Self-reevaluation, social liberation and reinforcement were frequently used in precontemplation, contemplation and preparation stages. Self-reevaluation, reinforcement, self-liberation were frequently used in action and maintenance stages. 4. Pros of exercise behavior began to be higher than cons of exercise behavior from the actions stage and continued to increase to maintenance stage. 5. Self-efficacy was higher in action stage than precontemplation, contemplation and preparation stages and the highest in maintenance stage.

Objectives : The aim of this study is to investigate the association between obesity indices(body mass index, weight, waist-hip ratio and waist circumference) in adolescents and the carotid intima-media thickness (C-IMT) in early adulthood. We also wanted to identify the best predictor for C-IMT among these obesity indices. Methods : This study used community-based prospective cohort study, known as the Kangwha Study, and the data we used were from subjects who were 16-years old in 1996 (defined as "adolescence") and 25 years-old in 2005 (defined as "early adulthood"). The 256 subjects (113 men and 143 women) who were used for analysis participated in both follow-ups, and they underwent B-mode ultrasonography of the carotid arteries at the early adulthood follow-up. Obesity indices were defined as the body mass index, weight, waist-hip ratio and waist circumference. The C-IMT was defined as the mean of the maximal IMT of each common carotid artery. The C-IMT and obesity indices associations were evaluated via multivariable regression, logistic regression and the receiver-operator characteristic curve analyses. Results : In men, all the obesity indices in adolescence were showed to have statistically significant positive association with C-IMT in early adulthood. However, no such relationship was showed in women. On multiple regression and logistic regression analysis, the waist-hip ratio showed the biggest relationship with the C-IMT among the 4 obesity indices. However, there were no statistical significant differences and no best predictor was found. For the women, the obesity incidences and C-IMT showed no relationships. Conclusions : This study suggested that obesity in adolescence was related to an increase C-IMT in healthy young Korean men.

This study examined the effects of self-concealment and satisfication among the basic psychological needs on the commitment to opposite-sex romantic relationships in early adulthood. The study examined the mediating effects of basic psychological needs, autonomy, competence, and relatedness, in the relationship between self-concealment and the commitment to opposite-sex romantic relationships. For this purpose, a self-report survey was conducted on 197 adults aged 20 to 29 who are currently in opposite-sex romantic relationships, and the collected data were analyzed using SPSS 26.0 and PROCESS MACRO v3.5. The main results of this study are as follows. First, gender, age, and duration of dating period among the subject's demo-social variables significantly impacted the commitment to opposite-sex romantic relationships. Second, satisfying relatedness among the basic psychological needs had the largest influence on the commitment to opposite-sex romantic relationships, and self-concealment negatively affected the commitment to opposite-sex romantic relationships. Third, relatedness from the basic psychological needs had a significant mediating effect between self-concealment and the commitment to romantic relationships. It can be seen that it is crucial to lower self-concealment and to satisfy relatedness among the basic psychological needs in order to promote commitment to romantic relationships in early adulthood. This study is meaningful in that it tried to reveal the influence of individual psychological factors on the commitment to the romantic relationship, and it is significant that it proposed a basis for intervention to promote the commitment to opposite-sex romantic relationships in early adulthood.
