China shows body size differences owing to varied climates, economic development, living standards, and ethnic distribution from region to region. That's why some regional research regarding body sizes is necessary for the advancement of clothing goods into China. Here, the materials of the Chinese standard "GB/T 1335-1997 Clothing Sizes" are analyzed to reveal the somatotypes of Chinese adults. Height, chest girth and waist girth were differently noticed in six areas. 1. The distribution rates of four body types (Y, A, B, C) were diverse in six regions. 2. Regional differences were seen as follows: 1) As for the height of male adults, areas 1(Northeast, Hwabuk) and 2(Central Western) were larger than the national mean. Areas 3(Gwangdong, Gwangseo, Bokgeon), 4 (Unnam, Gwiju, Sacheon) and 5(Downstream Jang River) were rather small. 2) As for the height of female adults, areas 1, 2 and 6 (Midstream Jang River) were larger than the national mean. Areas 3 and 4 were smaller than the average. 3) As for the bust girth of male adults, area 1 was the only area that exceeded the national mean. Areas 3 and 4 turned out smaller than the average. 4) As for the bust girth of female adults, areas 1, 2 and 6 exceeded the national average. The other three areas were lower. 5) As to the waist girth of adult males, areas 1 and 2 exceeded the national average. The other four areas were lower. 6) As to the waist girth of adult females, areas 1, 2 and 6 exceeded the national average. Areas 4 and 5 were lower. 7) In the height, bust girth and waist girth of male and female adults, most regions showed differences in means, regional distribution and regional rates.

Cardiovascular disease (CVD) risk factors may be acting several decades before CVD becomes manifest. Data from young subjects may be valuable in further elucidating at this issue. We evaluated the association between baPWV (brachial-ankle pulse wave velocity) and cardiovascular risk factors in apparently healthy young adults. A total of 46 male and 91 female adolescents aged $18{\sim}25 years$ were studied. baPWV increased in a dose-responsive manner as the number of metabolic syndrome components. In both gender groups, baPWV was positively correlated with age. In males, waist, circumference total cholesterol, and LDL-cholesterol were positively correlated with baPWV, and in females, blood pressure (BP) was positively correlated with baPWV. Age, gender, mean BP, and Homeostasis model assessment insulin resistance (HOMA-IR) were found to be independent factors associated with baPWV levels. In conclusion, mean BP, age, gender, and HOMA-IR were associated with baPWV in young adults. This result suggests that multiple cardiovascular risk factors may be associated with an increased risk of arterial stiffness in young adults.

Purpose: Malnutrition affects all age groups, but older adults are particularly more vulnerable to nutritional deficiencies. This study evaluated the age-specific factors affecting malnutrition in hospitalized older adults. Methods: A retrospective study was conducted on inpatient elderly people who received artificial nutrition from 2010 to 2017. Data of demographics, diagnosis, type of nutrition therapy, number of comorbidity, fall risk assessment, Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) score, and intensive care unit admission were collected. Malnutrition was defined as a body mass index (BMI) of less than 18.5 kg/m². Patients were classified as the young-old (65~74 years old), the old-old (75~84 years old), or the oldest-old (85 years old or older). Results: A total of 7,130 older adults were included, and 4,028 patients were classified as the young-old, 2,506 into the old-old, and 596 into the oldest-old. Proportion of malnutrition was higher in the oldest-old compared to the other groups. In multivariate analysis, parenteral nutrition, alcohol, and high risk of falls were factors affecting malnutrition in all groups. Parenteral nutrition and alcohol in the young-old, high risk of falls in the old-old, and male sex in the oldest-old were the factors affecting malnutrition by the age group. Conclusion: Older age was the most significant factor affecting malnutrition. Specific strategies by age are needed to improve nutritional status in hospitalized older adults as influencing factors for malnutrition vary among different age groups.

Insufficient dietary intake of vitamin A is one of the major nutritional problems for elderly adults in some parts of Korea. The objective of this study was to determine the vitamin A nutritional status of elderly adults in Asan, Korea by assessing the dietary intake and serum retinol concentration. Five hundred twenty four subjects (218 male and 306 female) over 65 years were recruited from city of Asan. Each subject was interviewed to assess the intake of vitamin A using a 24hr recall method and data were analysed from computer-aided nutrient analysis program. Blood samples after 12hr fasting were collected for serum retinol concentration and reverse phased HPLC with UV detector used. The results showed that subjects did not consume the sufficient amount of energy (82-85% of Korean RDA for male and 77-79% RDA for female) and vitamin A (59% RDA for male and 50% RDA for female). Range for retinol intake was 0 to $4342\;{\mu}g$ a day while that of beta-carotene was 65 to $31595\;{\mu}g$. Serum retinol concentrations were within a normal range for both male ($80\;{\mu}g/dl$) and female ($67\;{\mu}g/dl$) subjects. Many subjects (n=342) consumed less than 50% RDA of vitamin A. However, if retinol intake was high (> $37\;{\mu}g$), even with less than 50% RDA of vitamin A intake, serum retinol concentration was high ($75\;{\mu}g/dl$). Subjects showed normal serum retinol status even with low vitamin A intake. The results suggested that optimal intake ratio of dietary retinol and carotenoid is important to maintain an appropriate serum retinol concentration.

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.

To evaluate the periodontal status of Korean adults, 3,988 adults(20-69 years old) who lived in Kwangju, Chonnam, Taegu, and Kyungbuk districts were periodontally examined by plaque index(PI), calculus index(CI), gingival index(GI), periodontal disease index (PDI), and papillary bleeding index(PBI). The periodontal examination charts were grouped according to age and sex. And subsequently 200 periodontal examination charts in each age group were randomly selected according to sex. The differences of the indices among age groups and those between male and female in each age group were statistically analyzed by Chi-Square test. In PI, CI, GI, PDI, and PBI, there was no statistical significance in the difference between male and female in each age group(p>0.05). In male, PI of 60s age group($1.44{\pm}0.68$) was significantly higher than that of any age group(p<0.05), and in female PI of 20s age group($0.86{\pm}0.39$) was significantly lower than that of any other age group(p<0.05). CI of 60s age group in both male($1.67{\pm}0.70$) and female($1.63{\pm}0.91$) was significantly higher than that of any age group(p<0.05). GI of 20s age group in both male($0.85{\pm}0.66$) and female($0.67{\pm}0.60$) was significantly lower and GI of 60s age group in both male($1.37{\pm}0.60$) and female($1.44{\pm}0.84$) was higher than that of any age group(p<0.05). PDI in male was the lowest in 20s age group($0.70{\pm}0.73$), and was the highest in 60s age group($4.93{\pm}1.96$) (p<0.05). In female PDI of 20s age group($0.71{\pm}0.74$) was significantly lower than that of any age group(p<0.05). In male PBI of 20s age group($0.38{\pm}0.31$) was significantly lower than that of any age group(p<0.001). PBI in female was the lowest in 20s age group($0.35{\pm}0.30$) (p<0.001), and was the highest in 60s age group($1.09{\pm}0.76$) (p<0.05). The data insist that all the young populations of 20s age group should be interested in routine check for early diagnosis and prevention of periodontal disease, and a special education program of periodontal health care for young generation must be prepared, and the periodic recall check system for periodontal examination of middle age group must be supported by government.
