Objective: This study was designed to describe the trends in body mass index (BMI) during 6 years (2002-2008) and to identify associations between these trends and the amount of physical activity of South Korean career soldiers. Method: This study targeted the 40 993 (38 857 men and 2136 women) of the 58 657 career soldiers who had undergone four (2002, 2004, 2006, and 2008) biennial medical examinations conducted by the National Health Insurance Corporation; 17 664 soldiers with missing data on height, weight, and physical activity were excluded. A linear mixedregression model was used to categorize changes in BMI due to age versus those due to amount of physical activity. Results: Career soldiers experienced significant increases in BMI compared with baseline data gathered in 2002. The increases in each age group were as follows: men aged 20-29: 1.16, men aged 30-39: 0.61, men aged 40-49: 0.05, women aged 20-29: 0.35, women aged 30-39: 0.30, women aged 40 -49: 0.26, and women aged 50-59: 0.21. However, men aged 50 or older showed significant decreases (as high as 0.5) in BMI compared with baseline data obtained in 2002. They also experienced significant decreases in BMI compared with those who reported no physical activity. The differences between baseline and final BMIs were: 0.02 for men exercising 1-2 times per week, -0.07 for men exercising 3-4 times per week, -0.19 for men exercising 5-6 times per week, -0.21 for men exercising seven times per week, -0.05 for women exercising 1-2 times per week, -0.19 for women exercising 3-4 times per week, -0.30 for women exercising 5-6 times per week, and -0.30 for women exercising seven times per week. Conclusions: Obesity in South Korean career soldiers increased markedly between 2002 and 2008, and our data showed that the amount of physical activity was inversely related to increases in BMI. Policies to prevent obesity are needed to reduce this trend.

The purpose of this study was to assess the metabolic profile and nutrient intake data in Korean adolescents according to exercise regularity using the forth Korean National Health and Nutrition Examination Survey from 2008 data. A total of 834 Korean adolescents (440 boys, 394 girls) aged 12 to 18 years were classified into exercising male (EM), non-exercising male (NM), exercising female (EF), and non-exercising female (NF) groups. EM exhibited significantly higher weight (P<0.001), waist circumference (WC) (P<0.01) and body mass index (EMI) (P<0.001) than NM. EF showed significantly greater height (P<0.01), weight (P<0.001), we (P<0.001), and BMI (P<0.001) than NF. Although ratios of macronutrient intake were within the appropriate range in all groups, energy, riboflavin, vitamin e and calcium were assessed as in adequate by the nutritional adequacy ratio (NAR) in all groups. Moreover, EF and NF had inadequate intake of vitamin A and iron according to NAR, respectively. There were significant correlations between height and NAR protein (r=0.249, P<0.001), and mean adequacy ratio (MAR) (r=0.177, P<0.01), and between weight and NAR protein (r=0.180, P<0.01), and MAR(r=0.136, P<0.05) in EM. On the other hand, there were significant correlations between weight and NAR protein (r=0.270, P<0.01), we and NAR protein (r=0.271, P<0.01), and BMI and NAR protein (r=0.326, P<0.01) in NM. There were significant correlations height and NAR Fe (r=0.153, P<0.05) in EF. However, there were no significant correlations between metabolic factors and nutritional adequacy in NF. Although we noted no significant differences in MAR between the groups, the exercising groups showed higher MAR values than the non-exercising groups. Therefore, practicing of ideal dietary behaviors appears to be induced through physical activity and regular exercise in Korean adolescents.

The study aims to investigate the effects of media and self-image congruity of ideal body image on the dieting and exercising behaviors of Korean and U.S. female college students. This study focuses on the concept of self-image congruity in order to examine how respondents perceive actual and desired self-images compared to an ideal female body image selected by respondents. A self-administered survey was conducted, resulting in 331 total responses (194 from Korean students and 137 from U.S. students). The data were analyzed through descriptive analysis, t-test, exploratory factor analysis, and regression analysis using SPSS 23.0. The findings revealed significant differences between Korean and U.S. female college students. U.S. students were more exposed to body image ideals in the media than Korean students; however, Korean female students valued the information regarding ideal body image conveyed by the media more than U.S. respondents. Among Korean female students, exposure to media messages regarding ideal body image and media importance had significant effects on desired self-image congruity, while these factors were not significant among U.S. students. However, there was a negative effect of media exposure on actual self-image congruity among U.S. respondents only. Additionally, the study uncovered that Korean students manage their body image through dieting behaviors while U.S. respondents manage body image through exercise behaviors (weight training as well as cardiovascular exercise). The study provides further support for self-image congruity, which extends its applications to the body image field.

This study was conducted to test the effects of participation in 12-week program of boxing aerobics by obese middle-aged women on their body composition, blood constituents, and vascular compliance The samples are the middle-aged women in their forties or more, who has 30% or more body fat percentage, but has no medical history in cardiovascular disorders or metabolic diseases. The samples are divided into 8 of exercising group, and 8 of control group by random assignment. The intensity of boxing aerobics was HRmax 50% for the initial 4 weeks, HRmax 60% for the 5th to 8th week, and HRmax 70% for the 9th to 12th week. Each session took 60 minutes. The result is as follows. First, as a result of participating in the boxing aerobics program, body weight, body fat percentage, and muscle showed significant differences depending on the measuring period and the interacting term of the group and measuring period(p<.001), and the result of t-test on the sample matched to each group's measuring time also showed the significant increase or decrease in the exercising group(p<.001). Second, as a result of participating in the boxing aerobics program, the exercising group's TC, TG, HDL-C, and LDL-C, all showed significant differences in accordance with each group, measuring time, and the interaction term between groups and measuring time(p<.01, p<.001), and the result of t-test on each group's samples matched to the measuring time also shows significant increase or decrease in the exercising group(p<.01). Third, as a result of participating in the boxing aerobics programs, the vascular compliance of right hand, left hand, right hand, and left hand showed significant differences in accordance with each group, measuring time, and the interacting term between the measuring time and the group(p<.001), the t-test results of the samples matched to the each group's measuring time also showed significant differences in the exercising group(p<.001). To summarize the results above, it is suggested that the 12-week boxing aerobics program can improve body composition, blood constituents, and the blood circulation, which may prevent or enhance relevant diseases such as cardiovascular disorders.
