Objective To explore the relationship between obesity and the various parameters of physical fitness and provide the basis of physical fitness management for people.Methods A total of 725 male college students recruited from a University in Yangzhou.Height,weight,waist circumference and physical fitness of the subjects were measured.According to Obesity criteria (BMI and/or WC) ,the college students were divided into the following 4 groups(BMI obesity group(BOG),WC obesity group(WOG),BMI and WC obesity group(BWOG) and normal group(NG)).Logistic regression analysis was used to explore the relationship between obesity and physical fitness.Results (1) Significantly,1500m (P<0.01) of BWOG,BOG and WOG,push-ups (P<0.01) and standing time on one foot with closed eyes (P<0.01) of BOG and WOG and whole body reaction time(P<0.01) of BOG were lower than that of NG.(2) Vital capacity of BWOG and WOG (P<0.01),and grip strength (P<0.01) and back strength of BWOG and BOG (P<0.05) were higher than that of NG.(3) Multiple logistic regression showed that the odds ratios of WOG(βBOG=-1.002,OR=0.367,95%CI=0.191-0.702,P<0.01) and BOG(βWOG=-1.785,OR=0.169,95%CI=0.038-0.772,P<0.05) for low 1500m subjects were higher,of BWOG(βBWOG=1.776,OR=5.901,95%CI=1.298-26.828,P<0.05) and BOG(βWOG=1.681,OR=5.365,95%CI=1.667~24.670,P<0.05) for high vital capacity subjects were higher, of BOG for subjects of low Push-ups(βBOG=-0.658,OR=0.518,95%CI=0.280-0.960,P<0.05) and whole body reaction time(βBOG=-0.902,OR=0.405,95%CI=0.213-0.775,P=0.005) were higher,of WOG for high back strength(βWOG=-1.583,OR=0.207,95%CI=0.045-0.946,P<0.05) were higher while of BWOG and BOG for high grip strength subjects (βBWOG=1.786,OR=5.974,95%CI=1.315-27.155,P<0.05;βBOG=0.712,OR=2.036,95%CI=1.088-3.806,P<0.05) were higher,as compared to the NG.Conclusions ubjects of BWOG,BOG and WOG show reduced cardiorespiratory,BOG and WOG show lower upper arm muscular endurance and balance.The subjects of BOG show lower agility,BWOG and WOG show increased muscular strength and vital capacity while the subjects of BWOG have higher vital capacity,upper arm muscular and back strength.

Survey on Health Status and Food Habits of Male College Students in Wonju Area According to Drinking Behavior

This study was performed to investigate the health status and food habits of male college students in Wonju according to drinking behavior. A total of 204 (drinking group: 133, non-drinking group: 71) male college students were recruited and a questionnaire-based survey was conducted. General characteristics, drinking-related factors, health status, and food habits were investigated. Data were analyzed by SPSS program (ver 21.0). The type of residence (P<0.05) and obesity rate (P<0.05) were significantly different by drinking status. Frequency of drinking was 65.2%, and 39.9% of subjects started drinking upon entering college. The motivation to start drinking was 'from necessity'. Reason for drinking was 'Social relations'. The most frequent drinking opportunity in college was 'membership training'. The favorite kind of drink was beer. Health status factor scores for 'concerns about health (P<0.05)', and 'smoking (P<0.05)' were significantly higher in drinking group than those in non-drinking group. Food habits score (drinking group: 50.9 vs non-drinking group: 52.4, P<0.01) was significantly lower in the drinking group. Scores for 'I have breakfast regularly (P< 0.05)', 'Do not eat the junk food often (P<0.05)', and 'Do not eat out often (P<0.05)' were significantly lower in the drinking group. 'Drink milk every day' was significantly higher in the drinking group.

Food Habits and Dietary Behavior Related to Using Processed Food among Male College Students Residing in Dormitory and Self-boarding in Gangwon / 대한지역사회영양학회지

The purpose of this study was to examine food habits and dietary behavior related to using processed food among male college students residing in dormitory and self-boarding in Gangwon. A total of 344 students (dormitory group: 227, self-boarding group: 117) were surveyed from May to June of 2012. The results are summarized as follows: self-boarding group had a significantly higher frequency of skipping breakfast and lunch and frequency of out meal compared with the dormitory group (p < 0.05, p < 0.05, p < 0.05 respectively). The self-boarding group had a significantly lower the score of 'eat vegetables and Kimchi at every meal' (p < 0.001) and 'eat a variety of food everyday' (p < 0.001) compared with the dormitory group. The self-boarding group had a significantly higher the preference for meat products (p < 0.05) and canned food (p < 0.01) for selecting processed food compared with the dormitory group. The consideration for selecting processed food was ranked by 'taste', 'price', 'expiration', 'appearance' and 'nutrition' in both dormitory and the self-boarding group. In the dormitory group, nutrition labels were identified certainly 2.6%, sometimes 12.8%, and rarely 17.2%. In the self-boarding group, nutrition labels were identified certainly 1.7%, sometimes 18.0%, and rarely 24.8%. The necessity of nutrition education was high in both dormitory group (51.6%) and the self-boarding group (62.4%). Therefore, development of an educational program and application of the information from nutrition labels for male college students, especially self-boarding students will be effective in improving dietary life in order to maintain healthy dietary habits.

A Evaluation Study on Nutrient Intake and Diet Quality of Male College Students According to Packyear in Korea

The purpose of this study was to compare the nutrient intake and diet quality of male college student according to smoking groups. Subjects were recruited and divided into three groups according to the smoking, which included non-smoker (n = 100), light-smoker (n = 78; packyear or = 5). Subjects were interviewed using a general questionnaire, 24-hour recall method for dietary intake and diet quality. The average age of the subjects were 22.7 years for non-smoker, 23.5 years for light-smoker, and 23.4 years for heavy-smoker. Also the results showed that the heavy-smoker was significantly more often to drink coffe and alcohol compared with the other two groups (p < 0.001, p < 0.05). The mean daily energy intake was 2278.1 kcal in non-smoker, 2148.3 kcal in light-smoker, and 2144.4 kcal in heavy-smoker. The heavy-smoker consumed significantly lower intakes of vitamin C (p < 0.001), calcium (p < 0.01), animal calcium (p < 0.01), and potassium (p < 0.05) compared to the non-smoker and light-smoker. Also NAR (Nutrient Adequacy Ratio), ND (Nutrient Density), and INQ (Index of Nutritional Quality) of these nutrients in heavy-smoker were lower than the other two groups. Mean adequacy ratio (MAR) was 0.78 in non-smoker, 0.78 in light-smoker, and 0.74 in heavy smoker (p < 0.05). The heavy-smoker consumed significantly lower intakes of fruits (p < 0.001) compared to the non-smoker and light-smoker. The DVS (Dietary Variety Score) of heavy-smoker (26.8) was significantly lower than that 30.4 of non-smoker and 31.5 of light-smoker (p < 0.01). In conclusion, heavy-smoker man have low intake status of vitamin C, calcium and potassium, and partly low diet quality. Therefore it was needed that well planed diet to replace the nutrients supplied from excluded food groups in heavy- smoker.
