This study aimed to investigate the need for dietary education and programs for young Koreans belonging to single-person households in the metropolitan area. A total of 500 young adults aged 19-34 participated in the study through an online survey. Participants responded to questions on general characteristics, dietary problems, and the need for dietary education and programs. The subjects were divided into three groups as follows: Undergraduate students, employed workers, and others. Among the subjects from single-person households, 20.2, 67, and 12.8% were undergraduate students, employed workers, and others, respectively. When asked for their estimation of an appropriate self-pay when participating in a cooking class, 39.8% of total subjects responded '5,000-10,000 won'. The most preferred program for young adults in single-person households was the 'support food package'. For the preferred method of dietary education, undergraduate students showed a greater preference for classes 'at campuses'. However, employed workers and others had a higher preference for 'non-face-to-face online classes'. Undergraduate students tended to generally have a higher preference for dietary education and support programs compared to employed workers and others. This study provides data that will be useful for establishing healthy dietary policies and education programs for young single-person households in Korea.

Background: Head and neck squamous cell carcinoma (HNSCC) is the 8th most common cancer worldwide. Although older age, male gender, smoking and alcohol consumption are known risk factors, an increasing number of HNSCC patients are without typical risk factors. Our aim was to define demographics of HNSCC in Iran and the potential risk factors related to Iranian ethnicity and lifestyle. Methods: We conducted a cross-sectional analytical study on 262 patients with primary SCC of the larynx, hypopharynx or tongue referred to our pathology department during 1995-2010. Patients' demographics, tumor characteristics and risk factors such as smoking, alcohol consumption and anemia were analyzed and compared in two groups of patients: over 40 years (older group) and 40 years or less (young group); Chi-square and Mann-Whitney analytical tests were employed. Results: 5.7% of patients were young adults. The male to female ratio was 1.5 in the younger group and 5.6 in the older group. In young adults, 40% of tumors were located in larynx and 40% in the tongue. Age >40 was significantly associated with laryngeal location (P<0.001). History of smoking and drinking was significantly associated with age >40 and SCC of larynx in both age groups. Cervical lymph node involvement was significantly correlated with SCC of tongue (P<0.001), however, considering young adults only, SCC of hypopharynx was most frequently accompanied by lymph node involvement (60%). The most prevalent tumor among men was SCC of larynx whereas SCC of hypopharynx was the most prevalent tumor among women (61%), of whom 18.2% were ${\leq}40$. Conclusions: The incidence of HNSCC among young adults seems to be higher in Iran compared to other countries. Reduction in exposure to known risk factors, especially tobacco smoking in forms of cigarettes and bubble pipes, and search for other causative agents of HNSCC in young population is recommended.

The purpose of this study was to investigate proportional characteristics of soft tissue profile in Korean young adults. The sample consisted of 50 young adults(25 males and 25 females) who had pleasing profile and normal occlusion. Soft tissue proportional analysis was performed on lateral cephalograms taken in natural head position. The results were as follows : 1. Mean and standard deviation of proportional analysis were obtained. 2. Horizontal and vertical dimensions were larger in male. But facial proportion had no sexual difference except upper/lower face height (p<0.05). Upper/lower face height was larger in female than in male. 3. Vertical dimensions, except SN-ST, had high correlation with horizontal dimensions. 4. Head positioning error of natural head position was smaller than inter -individual variability of SN line.

This article explored the perceptions of ‘family’and the factors related to respondents' definitions of a family. The data were collected from two types of people: one was 472 university students and high school students' parents who were asked whether or not each of 22 scenarios represented a‘family’, and the other was 40 young and middle-aged adults who were asked,“what is a family member?”. Results showed that (1) the overwhelming majority of respondents considered a married couple without a child(scenario #5) as a family and the least respondents agreed a divorced couple(scenario #18) as a family, (2) the majority perceived consanguinity, co-residence, parental status, and marital status to be important in the definition of a family, (3) middle-aged adults were more likely than young generation to agree that consanguinity and paternal relations were important in determining what a family member is.

Young adults bear a higher risk of reproductive health problems than adults. Cases of unwanted pregnancies and their attendant complications reportedly rank among the highest in Africa. This study therefore investigates reproductive health and use of health information among university undergraduates in Nigeria. Correlational research design was adopted using descriptive survey method. Questionnaire was designed and used as survey instrument. The study used 25% of 6,978 undergraduate students from government and private universities in Abeokuta, Ogun State between 16-24 years old from each of the 35 departments that made up 8 colleges in the two universities. A total number of 1,745 copies of questionnaire were administered to the respondents out of which 1,500 copies were filled completely and retrieved making the response rate to be 86.95%. The findings of this study show that friends, parents and relatives were the closest sources of health information the respondents have used for reproductive health purposes. Utilisation of health information through information resources was effective. The study also concludes that cultural value, level of education and unfriendly attitude of health officials were parts of the major problems confronting effective utilization of reproductive health information among young adults in Nigeria.

Purpose : Tandem stance is a clinical measure of standing balance considered to assess postural steadiness in a heel-to-toe position by a temporal measurement. The aim of this study is to investigate postural steadiness and to explore the weight distribution between legs during 25s of quiet stance and tandem stance(right foot was leading) in healthy young adults. Methods : 107 healthy young adults(mean age 21.1 years) are participated. Weight distribution beneath both feet and sway distance were recorded while the subjects performed 25s of quiet stance and tandem stance. Results : Subjects placed more weight on the rear leg in tandem stance and on the left foot in quiet stance. So, quiet stance and tandem stance is not a task for equal weight bearing. Subjects show larger sway distance in anteroposterior direction of tandem stance than quiet stance. Conclusion : The results of this study will be useful to researchers and clinicians using tandem stance measures to evaluate postural steadiness and to predict fall. The results suggest that tandem stance is useful to treat of weight distribution and to improve of balace in elderly adults and stroke patients.

PURPOSE: This study examined the effective impact of self and resistive and ultrasound-biofeedback diaphragm breathing on the pulmonary function and diaphragm thickening ratio of young adults. METHODS: Thirty normal adults were assigned randomly to three experimental groups (self- diaphragm breathing (n=9), resistive-diaphragm breathing (n=11), ultrasound-biofeedback diaphragm breathing (n=10)). Each group participated for 15 minutes for times with a two minute rest between two sets. The subjects were assessed using the pre- and post- diaphragm thickening ratio and the pulmonary function (forced vital capacity, forced expiratory volume at one second, maximal voluntary ventilation, and respiratory rate) on the thirty subjects. A paired t-test was to determine the difference between before and after the experiment in each group of diaphragm breathing before and after the exercises. One-way ANOVA was used to determine the differences between the groups. RESULTS: The forced vital capacity and maximal voluntary ventilation measurements revealed a significant difference in the resistive-diaphragm breathing group than the other two groups. On the other hand, there was no significant difference between the self-diaphragm breathing and ultrasound-biofeedback breathing groups. CONCLUSION: The resistive-diaphragm breathing group showed greater improvement in the pulmonary function than the other two groups. Therefore, resistive-diaphragm breathing will improve the pulmonary function on normal young adults.

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.

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.
