This study assessed gender differences of 'solo eating' perceptions and dietary behaviors among college students residing in Seoul and Kyongki province. Two types of questionnaires were used to analyze perception and dietary behaviors of subjects: a cross-sectional survey (N=893) and AGA (Associative Group Analysis; N=50). Women ate significantly more and intook a greater variety of foods when eating together (P<0.05). Men, on the other hand, showed no difference in these variables. Women, compared to men, spent more time eating both alone and together (P<0.001). In the associative group analysis (AGA), women showed a different semantic value for 'solo eating' compared to men. Women also tended to feel lonely when they ate alone and had positive images of eating together. Students began to decide their own dietary behaviors after junior and high school. Dietary lives of Koreans have rapidly changed along with social changes over the past half century. These research findings will contribute to more comprehensive and efficient nutrition education programs for preventing lifestyle-related diseases in the early stage of adulthood.

Objectives: Bone health in early adulthood, as individuals approach peak bone mass, plays a critical role in preventing osteoporosis later in life. This study aimed to investigate the associations between lifestyle and dietary factors, anthropometric measurements, and urinary bone resorption markers in young adults. Methods: A cross-sectional study was conducted with 100 healthy Korean adults (50 men and 50 women) in their 20s and early 30s. Bone mineral density (BMD), anthropometric measurements, dietary intake (24-hour recall), and urinary bone resorption indicators (deoxypyridinoline and N-terminal telopeptide of type I collagen) were analyzed. Variables were compared between the osteopenia and osteoporosis groups (OSTEO group: 30% men and 60% women) and the healthy control group. Results: Men in the OSTEO group were significantly taller than those in the control group (P < 0.05). Women in the OSTEO group had significantly lower body weight and body composition (muscle and body fat) than those in the normal group (P < 0.01). Men in the OSTEO group had a significantly higher intake of animal calcium (Ca) than those in the normal group (P < 0.05). Women in the OSTEO group had significantly higher dietary fiber, vitamin A, Ca, plant Ca, and potassium intake than did those in the normal group (P < 0.05). There were no significant differences in caffeinated beverage consumption, eating habits, or urinary bone resorption indicators between the OSTEO and control groups of either sex. Conclusions: In our study of young South Korean adults, we observed low bone density levels, with particularly low BMD in taller men and underweight women. We found a higher nutrient intake in the OSTEO group, indicating the possibility of reverse causality, a phenomenon often found in cross-sectional studies. Therefore, there is a need to further elucidate dietary factors related to osteoporosis in young adults through prospective cohort studies involving a larger population.

The study is to verify the mediating effect of self-compassion in the relationship between abandonment anxiety and relationship addiction. To this end, a questionnaire survey was conducted on 250 men and women in early adulthood, using the scales of abandonment anxiety, self-compassion, and relationship addiction, of which 237 were used for the final analysis. Descriptive statistics and correlation analysis were performed using the SPSS 21.0 program, and mediating effects were confirmed using the PROCESS macro. The results of the study are as follows. First, abandonment anxiety showed negative correlation with self-compassion, and positive correlation with relationship addiction. Self-compassion showed negative correlation with relationship addiction. Second, in the relationship between abandonment anxiety and relationship addiction, self-compassion showed a partial mediating effect. Through this study, the relationship between abandonment anxiety and relationship addiction and the effectiveness of self-compassion to manage it were confirmed. Based on the results of this study, the significance and limitations of this study and suggestions for subsequent studies were presented.

Prevalence of obesity in Korean children and adolescents has dramatically increased since the last 10-20 years. It is important to initiate prevention efforts early in childhood because prevalence of obesity in adolescence is the strongest predictor of its prevalence in adulthood. Intrauterine life, infancy, and preschool years may comprise the critical periods that are essential for the long-term regulation of energy balance therefore, obesity-prevention strategies should be initiated in utero and continued throughout childhood and adolescence. Families with high-risk children should be provided early education about maintaining normal weight. Encouraging physical activity and, especially, avoiding inactivity, are key challenges in the prevention of future obesity. Schools should be primarily involved in educating parents to discourage their children from excessively watching TV or playing computer games and eating unhealthy snacks and food. The involvement of medical practitioners is also important, especially, in the case of obese parents, obesity prevention strategies should be promoted from the first visit of pregnant women to the physicians. Health professionals can also be involved in obesity prevention because they are ideally equipped to identify young children at risk of obesity. Community and nation-wide efforts to increase awareness and promote environments that encourage physical activity and healthy nutrition are required.

Osteoporosis is a major health problem confronting middle-aged women today. Enhancing calcium intake in early adulthood can increase the rate of calcium gain in bone. In this study, we investigated the association of bone health-related nutritional knowledge levels with calcium-related dietary behavior and nutrition education among women. Data were collected using questionnaires from 347 women aged 20~30 residing in Gyeonggi-do. Subjects were categorized into two groups according to their bone health-related nutritional knowledge (high or low-knowledge group). Knowledge related to bone health and calcium, and dietary habits was assessed, and the preference for and intake frequency of calcium-rich food were collected and analyzed using food frequency questionnaires. The high-knowledge group showed a significantly higher rate of nutritional education experience (33.9%) when compared with the low-knowledge group (18.9%). Not only were the perceptions regarding milk and dairy products more positive in the high-knowledge group (P<0.05), but the intake frequency of calcium-rich foods, such as tofu, soybean, and anchovies, was also higher in this group compared to the low-knowledge group (P<0.05). Overall, the preference for all calcium-rich foods was positively correlated to their intake frequency (P<0.05). Nutrition education experience and the recognition of the need for such education were positively correlated with the bone health-related nutrition knowledge score (P<0.05). In conclusion, bone health-related nutritional knowledge can affect calcium-related dietary behavior and increase the intake of calcium-rich food of 20~30-year-old women and this can contribute to the prevention of osteoporosis. To improve bone health-related nutritional knowledge among young women, it may be important to provide nutrition education.

BACKGROUND/OBJECTIVES: This study examined the relationship between famine exposure in early life and the risk of type 2 diabetes in adulthood during the 1959-1961 Chinese Famine. SUBJECTS/METHODS: A total of 3,418 individuals aged 35-74 years free of diabetes from two studies in 2006 and 2009 were followed up prospectively in 2009 and 2012, respectively. Famine exposure was classified as unexposed (individuals born in 1962-1978), fetal exposed (individuals born in 1959-1961), child exposed (individuals born in 1949-1958), and adolescent/adult exposed (born in 1931-1948). A logistic regression model was used to assess the relationship between famine exposure and diabetes after adjustment for potential covariates. RESULTS: During a three-year follow-up, the age-adjusted incidence rates of type 2 diabetes were 5.7%, 14.5%, 12.7%, and 17.8% in unexposed, fetal-exposed, child-exposed, and adolescent/adult-exposed groups, respectively (P < 0.01). Relative to the unexposed group, the relative risks (95% confidence interval) for diabetes were 2.15 (1.29-3.60), 1.53 (0.93-2.51), and 1.65 (0.75-3.63) in the fetal-exposed, child-exposed, and adolescent/adult-exposed groups, after controlling for potential covariates. The interactions between famine exposure and obesity, education level, and family history of diabetes were not observed, except for the urbanization type. Individuals living in rural areas with fetal and childhood famine exposure were at a higher risk of type 2 diabetes, with relative risks of 8.79 (1.82-42.54) and 2.33 (1.17-4.65), respectively. CONCLUSIONS: These findings indicate that famine exposure in early life is an independent predictor of type 2 diabetes, particularly in women. Early identification and intervention may help prevent diabetes in later life.

This study analyzes the difference in total cholesterol blood concentration according to dietary characteristics and health characteristics, as well as general characteristics, and the relationship between that factor and total cholesterol level according to the diagnostic criteria for dyslipidemia, and then compares and analyzes the relative risk ratio of significant factors for the occurrence of dyslipidemia. As a result, the total cholesterol blood concentration increases with age, so continuous management is necessary. Mainly, waist circumference level in early adulthood, regular exercise of appropriate intensity in late adulthood, and subjective health level management in the elderly are necessary. It was found that it was necessary to manage BMI level and eating-out level overall.

Purpose: The reproductive health of women in early adulthood can affect pregnancy, childbirth, and menopause in later life. Menstrual symptoms not only affect daily life, but are also a reflection of a woman's reproductive health. This study was conducted to explore the factors affecting menstrual symptoms among university students. Methods: The general characteristics, life style, menstrual characteristics, stress, and menstrual symptom of 177 female students were assessed through an online survey at one university. An independent sample t-test, one-way variance analysis, correlation analysis, and multiple regression analysis were performed using the SPSS 22.0 program. Results: The menstrual symptom score was 91.68±32.11 points, and the score of 'mood change' was the highest. Stress (��=.38, p<.001), amount of menstruation (��=.20, p=.001), menarche age (��=-.18, p=.003), health problems (��=.16, p=.010), and age (��=.15, p=.016) were found to have a significant effect on menstrual symptom, and the explanatory power of the regression model was 40%. Conclusion: This study investigated the degree and influencing factors of menstrual symptom using the Korean Menstrual Symptom Scale (KMSS) developed for Korean university students. Among the factors influencing menstrual symptom, stress appeared to play a significant role. Stress management, observation of menstrual characteristics, and general health care are necessary to maintain a woman's reproductive health.

The purpose of this study was to survey body image according to BMI. The subjects were 600 students, data were collected by questionnaire surveys using convenience sampling and analyzed by the SPSS 20.0 program. Body mass index(BMI) and body image between high school and college students were significantly different. Although significant difference between two groups, BMI of high school and college students among women were not significant difference. BMI and body image according to gender were significantly different. Body image according to BMI between men and women were significantly different and expecially subjects of under weight had highest body image(F =15.86, p <.001). These results mean that body weight misunderstood by the early adulthood. It is needed to revise of perception on their own body weight in order to improve body image.

Purpose: Although it is well known thatmortality and morbidity due to cardiovascular diseases are higher in salt-sensitive subjects than in salt-resistant subjects, their underlying mechanisms related to obesity remain unclear. Here, we focused on salt-sensitive gene variants unrelated to monogenic obesity that interacted with sodium intake in humans. Methods: This review was written based on the modified $3^rd$ step of Khans' systematic review. Instead of the literature, subject genes were based on candidate genes screened from our preliminary Genome-Wide Association Study (GWAS). Finally, literature related to five genes strongly associated with salt sensitivity were analyzed to elucidate the mechanism of obesity. Results: Salt sensitivity is a measure of how blood pressure responds to salt intake, and people are either salt-sensitive or salt-resistant. Otherwise, dietary sodium restriction may not be beneficial for everyone since salt sensitivity may be associated with inherited susceptibility. According to our previous GWAS studies, 10 candidate genes and 11 single nucleotide polymorphisms (SNPs) associated with salt sensitivity were suggested, including angiotensin converting enzyme (ACE), ${\alpha}$-adducin1 (ADD1), angiotensinogen (AGT), cytochrome P450 family 11-subfamily ${\beta}$-2 ($CYP11{\beta}$-2), epithelial sodium channel (ENaC), G-protein b3 subunit (GNB3), G protein-coupled receptor kinases type 4 (GRK4 A142V, GRK4 A486V), $11{\beta}$-hydroxysteroid dehydrogenase type-2 (HSD $11{\beta}$-2), neural precursor cell-expressed developmentally down regulated 4 like (NEDD4L),and solute carrier family 12(sodium/chloride transporters)-member 3 (SLC 12A3). We found that polymorphisms of salt-sensitive genes such as ACE, $CYP11{\beta}$-2, GRK4, SLC12A3, and GNB3 may be positively associated with human obesity. Conclusion: Despite gender, ethnic, and age differences in genetics studies, hypertensive obese children and adults who are carriers of specific salt-sensitive genes are recommended to reduce their sodium intake. We believe that our findings can contribute to the prevention of early-onset of chronic diseases in obese children by facilitating personalized diet-management of obesity from childhood to adulthood.
