Objective: The purpose of this study was to analyze and compare vertical ground reaction forces during sit to stand (STS) and gait between female elderly and young individuals using the Wii Balance Board (WBB). Design: Cross-sectional study. Methods: Fifty-one female elderly people (age: $75.18{\pm}4.60years$), and 13 young people (age: $29.85{\pm}3.69years$) performed the five times STS test and gait respectively on the WBB. We analyzed time (s), vertical peak (%), integral summation (Int_SUM, %), and counter variables (%) in STS and 1st peak (body weight, BW%), 2nd peak (BW%), peak minimum (BW%), time (second), center of pressure (COP) path length (mm), and Int_SUM (BW%) in gait. The independent t-test was used to assess for differences in STS, gait ability, and general characteristics between the female elderly group and young adults group. With the first and last trials excluded, the mean value was obtained from the middle three of the five trials. Results: During STS, Int_SUM and time of young adults were significantly less than of the female elderly subjects. There were no significant differences in peak and counter variables. In gait, all variables (1st peak, 2nd peak, min, time, COP_path, and Int_SUM) showed significant differences between groups (p<0.05). This study demonstrated that the validity of vertical ground reaction forces occurring during STS and gait was significant in female elderly and young adults. Conclusions: Based on the measurement of vertical ground reaction forces in STS and gait using the WBB, it is possible to clinically improve the quality of geriatric physical therapy. Further studies are necessary to examine concurrent validity of elderly patients who have undergone total hip or knee replacement.

The main purpose of this research is to investigate the effect of Korean adults' perception of parent-child relation on their self-efficacy, child rearing practices, elderly parent care practices, and happiness. In this study the parent-child relation is a relationship between the adults' parents and the adults. The participants in the study were adults (2,632; male=1,275, female=1,357) with children in primary, secondary, and/or university, with an average age of 45.44-years-old (male=46.96-years-old, female=44.10-years-old). The results showed a direct influence of the adults' perception of parent-child relation on their self-efficacy and their child rearing practices, and an indirect influence on their happiness. This indicates that a more positive adult's perception of parent-child relation leads to higher self-efficacy and greater devotion to their child rearing practices. And furthermore, an elevated self-efficacy enhanced their happiness. Gender differences were found for the influence of adults' perception of parent-child relation on elderly parent care practices. For Korean male adults, a more positive perception of parent-child relation lead to a more active participation in elderly parent care practices. However, for Korean female adults no direct influence was found. Based on these results, a discussion of the influence of adults' perception of parent-child relation on the adults' psychological characteristics and family-members relationships is provided.

The purpose of this study was to promote an understanding of suicidal ideation and identify the factors that influence suicide ideation according to the life cycle of Korean adults. This study was a secondary analysis study using the Korea Health Panel 2016 data. Among adults over 19 years of age, 14,538 people with no missing values in suicidal ideation and influencing factors were classified into young adults (19-39 years old), middle-aged adults (40-64 years old), and the elderly (65 years or over). The data were analyzed by multiple logistic regression. The results showed that 2.9% (108 people) of young adults, 3.2% (181 people) of middle-aged adults, and 3.7% (80 people) of the elderly had suicide ideation over the past year. Factors influencing suicidal ideation by life cycle were anxiety, depression, drug use and quality of life for young adults, subjective health status, stress, anxiety, depression, drug use and quality of life for middle-aged adults. The factors affecting the elderly were body mass index, stress, anxiety, depression, and quality of life. Therefore, factors influencing suicidal ideation should be considered as a major factor for screening risk groups according to the life cycle, and differentiated intervention programs should be developed and provided to prevent and manage suicide in risk groups.

Purpose: This study aimed to identify and compare the risk factors of depression among middle-class Korean workers. Methods: A cross sectional study was designed for secondary data analysis. From the 8th Korean Medical Panel Survey (2008~2013), a total of 3,056 data was drawn and analyzed. With SPSS version 24, a developmental stage comparison, with the stage being young adults (20~39), middle-aged adults (40~64), and older adults (65+) were conducted. Frequency, percentage, 𝑥² test and logistic regression analysis were statistical tools used to analyze the data. Results: In all developmental groups, experience of frustration was found to be a common risk factor of depression. Stress from excessive task, peer-compared subjective health status, and self-perceived social class were risk factors of depression in the young adults and the middle-aged adults. Anxiety for the future significantly influenced depression in the middle-aged adults and older adults. Conclusion: Experience of frustration was a major risk factor of depression among Korean middle-class workers. Interventions to reduce depression need to be developed focusing on the specific risk factors by developmental stages such as experience of frustration, stress from task burden, poor peer-compared subjective health status and anxiety for the future.

BACKGROUND/OBJECTIVES: This study aimed to compare 24-h diet recall (DR) and 24-h urine collection (UC) for estimating sodium and potassium intakes and their ratio (Na/K), identifying factors associated with sodium and potassium intakes and Na/K, and identifying those who were likely to underestimate sodium and potassium intakes by DR. SUBJECTS/METHODS: A total of 640 healthy adults aged 19-69 yrs completed a questionnaire survey, salty taste assessment, anthropometric measurement, two 24-h DRs, and two 24-h UCs. RESULTS: The mean sodium and potassium intakes and Na/K were 3,755 mg/d, 2,737 mg/d, and 1.45 according to DR, and 4,145 mg/d, 2,812 mg/d, and 1.57 according to UC, with percentage differences of -9.4%, -2.7%, and -7.6% in the values between the two methods, respectively. Men, older adults, smokers, obese individuals, those who consumed all the liquid in the soup, and those who were found to be salty in the salty taste assessment consumed significantly more sodium; older adults, the heavy- activity group, and obese individuals consumed more potassium; and men, younger adults, smokers, and obese individuals had a significantly higher Na/K, according to UC. Compared with UC, DR was more likely to underestimate sodium intake in older adults, smokers, obese individuals, those who consumed all the liquid in the soup, and those who consumed eating-out/delivery food at least once a day, and potassium intake in older adults, the heavy-activity group, and obese individuals. CONCLUSIONS: The mean sodium and potassium intakes and Na/K estimated by DR were comparable to those measured by UC. However, the association of sodium and potassium intakes with sociodemographic and health-related factors showed inconsistent results when estimated by DR and UC. Factors influencing the underestimation of sodium intake by DR compared to UC should be further investigated.

Objective: The arm swing is associated with gait ability in healthy young adults. The purpose of this study was to examine the effects of arm swing during gait in healthy young adults. Design: Cross-sectional study. Methods: Forty-five subjects without any orthopedic or neurological injuries participated in this study. All subjects performed all three conditions according to the arm swing type as follows: first procedure (condition 1), walking as usual without arm swing constraint; second procedure (condition 2), constraint of dominant arm swing walking as usual; third procedure (condition 3), constraint of both arm swing walking as usual. Gait parameters such as gait velocity, stride length, cadence, step time, single limb support, and double limb support were measured in all arm swing conditions performed randomly, with the mean value obtained from three measurements. A rest period of 5 minutes was given to prevent repetition of each condition and learning effect. All data was analyzed using repeated measures ANOVA to notice the changes between arm swing conditions. Results: Within walking conditions, significant difference of gait velocity, stride length, cadence, and double limb support was noticed (p<0.05), except step time and single limb support. Gait velocity and stride length were significant reduced, and in cadence and double limb support were increased (p<0.05). Condition 3 had the most significant decrease of gait ability compared with condition 1 (p<0.05). Conclusions: These finding suggested that constraint arm swing conditions reduced gait ability in healthy young adults. Also, these findings can be utilized as a reference to future studies that not only pelvic, knee and ankle, but also upper limb affect to gait ability.

Introduction: Colorectal carcinoma (CRC) is the most common gastrointestinal malignancy in the older population, but it is also quite frequent among young adults in developing countries. The aim of this study was to update the trends of clinicopathological features of CRC in young Nepalese. Methods: A retrospective comparative study on the data retrieved from the surgical records of all patients between 20 to 39 years of age with CRC was carried out for periods of 5 years each from 1999 to 2003 (early) and 2004 to 2008 (recent), treated at Tribhuvan University Teaching Hospital, Kathmandu, Nepal. Results: The number of young adults with CRC increased from 28 to 34. However, the proportion of young patients in both groups was 28% of all CRC patients. The mean ages were $34{\pm}4.7$ and $31.8{\pm}5.1$ years in early and recent 5 years, respectively, and the male female ratio changed from 2:3 to 4:3. Abdominal pain as the most common presenting symptom was replaced by bleeding per rectum in recent years. The mean duration from onset of symptoms to seeking medical advice decreased from 7.8 months to 5.6 months in recent years. More patients (85.3%) were subjected to endoscopic examination in recent years than early years (60.7%) and right colonic cancer increased from 10.7% to 26.5%. However, the rectum was the commonest site in both early (71.4%) and recent (50%) groups. CRC was detected significantly at an earlier stage (7.1% vs 32.4%) in recent years with large proportion of modified Dukes B stage. Poorly differentiated adenocarcinoma was the predominant histology in both groups (50% vs 60.7%). Curative resection had risen in recent years (39.3% vs 73.6%). Conclusion: CRC among Nepalese young adults accounts for a high incidence (28%) of all CRC cases. Although right sided colonic cancer has been increasing, rectum is the commonest site. There is also an increasing trend for diagnosis at earlier stages of the disease which can be treated with curative intent.

This study aimed to understand the meaning and essence of the experience of bodily change in young-old adults. van Manen's hermeneutic phenomenological method was utilized. Study participants were 11 elderly who 65 to 74 residing in J city. Data were collected from in-depth individual interviews with the participants from July to September 2016. The essential themes were identified regarding the experience of bodily change in young-old adults: 'self-pity about perceived aging', 'myself projected onto others', 'wants to hold on passing of the time', and 'priority on wellbeing than appearance'. The present findings can be used as important basic data for the development of nursing interventions and improving quality of life for young-old adults.

Objectives: We examined which socioeconomic and intergenerational characteristics were associated with the level of intention to marry among Korean men and women in young adulthood. Method: Data came from 351 men and 391 women who were 25-34 years old, had never been married, and had at least one living parent. We conducted multiple regression analyses by gender after controlling for age and current romantic relationship. Results: Among the socioeconomic characteristics, more years of education was linked to both men's and women's higher levels of intention to marry. For women, having a secure, full-time job was related to greater intention to marry. For men, the higher their subjective socioeconomic status, the greater their intention to marry. Among intergenerational characteristics, both men's and women's positive attitudes toward supporting elderly parents were related to a higher level of intention to marry. For men, the frequency of providing instrumental support for their parents was negatively associated with the men's intention to marry. For women, higher levels of agreement with parents' responsibility to support their adult children as well as greater affection for their parents were positively related to greater intention to marry. Conclusions: The findings suggest that young adults' socioeconomic resources and the family context are important predictors of young adults' marital intentions. The results also reveal gender differences in the factors associated with young adults' marital intentions.

Background and Objectives: To evaluate the impact of smoking in young adults on the risk of cardiovascular disease (CVD) and the clustering effect of behavioral risk factors such as smoking, obesity, and depression. Methods: A Korean nationwide population-based cohort of a total of 3,280,826 participants aged 20-39 years old who underwent 2 consecutive health examinations were included. They were followed up until the date of CVD (myocardial infarction [MI] or stroke), or December 2018 (median, 6 years). Results: Current smoking, early age of smoking initiation, and smoking intensity were associated with an increased risk of CVD incidence. Even after quitting smoking, the risk of MI was still high in quitters compared with non-smokers. Cigarette smoking, obesity, and depression were independently associated with a 1.3-1.7 times increased risk of CVD, and clustering of 2 or more of these behavioral risk factors was associated with a 2-3 times increased risk of CVD in young adults. Conclusions: In young adults, cigarette smoking was associated with the risk of CVD, and the clustering of 2 or more behavioral risk factors showed an additive risk of CVD.
