The effect of interpregnancy interval on birthweight of the subsequent child was investigated for the 1,347 womens of 25 to 40 years old age who visited OBGY and Pediatric department of the general hospital in Taegu city. Questions in designed questionnaire were asked by student interviewers who were trained in nursing school. Mean birth weight by interpregnancy intervals were compared by the intervals of 6 months. Mean birth weight increased from 3,250 grams for intervals of 6 months to 3,357 grams for intervals of 25-30 months, hut the difference was not statistically significant(=0.47). Correlations between the continuous variables which were suspected as con founders and interpregnancy interval and birth weight were investigated. The coefficient of correlation between maternal age and interpregnancy interval was 0.39, between gestational period and birth weight 0.30 and between prepregnant weight and birth weight 0.16 and between birth weight of first baby and birth weight(of second baby) 0.44. But maternal age, gestational period and prepregnant weight were not considered as confounder, because they were not correlated simultaneously with birth interval and birth weight. Associations between the discrete variables which were suspected as confounders, and interpregnancy interval were investigated by Chi-square test. Associations between interpregnancy interval and educational level of mothers, types of husband's occupation, types of medical security, sex were not significant(P-values were 0.59, 0.75, 0.75, 0.82 respectively), so we did not considered these variables as confounding variables. In multiple regression analysis of birth weight, significant variables were birth weight of first baby, gestational period, sex of neonate and prepregnancy body weight of mother. Of the 1,347 births, the rate of low birth weight was 2% (27 birth). The rate for interpregnancy interval 7-12 months was highest as 3.6% and that for 13-18 months was lowest as 0.6%, but there was no regular tendency related with interpregnancy interval.

The purpose of this research is to analyzed the Korean adolescents' weight control behaviors by BMI(Body Mass Index) and body shape perception. The data of this study abtained 73,238 adolescents, aged 12-18years from the '2010 6th Korea Youth Risk Behavior web-based Survey. The data were analyzed by frequency, percentile, chi-square test, Binominal Logistic Regression analysis. The results of this research were as following. First, the answer to question about adolescents' body shape perception is high in "normal" and "a little fat", but the result of BMI show that the most of them are in "underweight". Second, the female students tends to perceive themselves obese than male students do. Third, the female student try to lose weight but male student try to gain weight. Also the higher BMI is, the more the student have tendency to try to lose their weight. In conclusion, BSP leds directly weight control behavior, so in order to reduce unnecessary weight loss or improper methods weight control behavior. It is important to educate the students to have a sound perception about body shape.

The seven (7) housewives were used as subjects at three times per weeks for twelve (12) weeks in order to find out the effects of aerobic exercise and weight training on body composition and blood lipid. Each subject's weight, lean body mass, percent body fat, BMI and blood lipid were measured immediately after the training and the results compared with the same prior to exercises were obtained as follows ; 1. The weight and percent body fat of the subjects were slightly but not significantly decreased, however the lean body mass following training was significantly increased with 1.3 %. BMI S RBW were also not significantly decreased. 2. Calory intake was 1929.9 cal before the training and 1896.0 cal after the training, which doesn't shows much difference. 3. The blood lipid such as TC and LDL-C were a little increased after the training, but HDL-C shows significant increase of 22.7 %, and HDL-C/TC was significantly increased with 13.2 % (p<.05 ) as well. However, TG shows significant decrease (p<.05 ).

The study was carried out to determine if a difference in initial chick weight was still evident in market body weight(6 or 8 week body weight) of broilers. The data of a total of 800 broiler commercial chick raised at Poultry Breeding Farm, Seoul National University from Aug. 6, 1981 to Oct. 1, 1981 were analysed. The results were summarized as follows: 1. Although the initial chick weight was about the same, male chick grew more rapidly than female and sex difference was the most striking factor in growth rate of broiler in this analysis. 2. The relationship between initial chick weight and body weight after hatching was decreased to the increase of weeks of age in both sexes. Though the correlation coefficients of the 6 week and 8 week body weight to the initial chick weight were 0.15 & 0.15 in female and 0.18 & 0.17 in male, the relationship was highly significant in both sexes. 3. Regressions of 6 and 8 week body weight on the initial chick weight in both sexes indicate that, for each increase of one gram in weight of chick at hatching, the average increase in body weight was 8.33 gram ＆ 10.07 gram in female and 7.85 gram ＆ 11.28 gram in male. Results show that the initial chick weight (1 day of age) influence average body weight of commercial broiler at 6 and 8 weeks of age.

The purpose of this research was to investigate nursing students' attitude toward body weight control, food behaviors according to their recognition, satisfaction on body image and Body Mass Index(BMI). The subjects were 273 nursing students. A survey was conducted using a self administered questionnaire. The data were an analyzed by a SPSS program. The majority of the surveyed participants were normal range for body mass index(BMI). Most of nursing students preferred a thin body image and were not satisfied with their body image. Most also controlled their body weight for appearance by exercising and the other efforts to change the body weight. From the above results, it is considered that nursing students need to establish proper self-recognition and dietary behaviors for their body images and counseling for desirable body weight control methods.

This study was conducted to identify factors influencing weight loss efforts in hypertensive patients with obesity in Korea using data from the 2016-2019 National Health and Nutrition Examination Survey. Weight perception, weight loss efforts, and weight control methods were investigated for 1,910 subjects. Data were analyzed using descriptive analysis, cross-tabulation analysis and logistic regression. Among obese hypertensive patients, 12.6% perceived their weight as normal. Weight loss efforts were 2.03 times (95% CI: 1.48 to 2.78) higher in people with overweight perception than those with normal weight perception, and 1.74 times (95% CI: 1.33 to 2.26) higher in women than in men. In addition, those with class 1 obesity were 1.50 times (95% CI: 0.85 to 2.65) higher than those with class 3 obesity, and those with class 2 obesity were 2.16 times (95% CI: 1.16 to 4.00) higher than those with class 3 obesity. These results suggest that weight management approaches for hypertensive patients with obesity should be individually designed according to weight perception, gender, and obesity class.

The aim of this study was to investigate the eating behavior and nutritional status of subjects according to their purpose of exercise. A total of 214 subjects, 20 to 30 years of age, who visited fitness centers in Seoul were enrolled. Anthropometrics, exercise habits, nutritional knowledge, and eating behaviors were analyzed using a questionnaire. Nutritional status was assessed by serial 24 h recalls. The subjects were divided into two groups based on their purpose of exercise: increasing muscle (Muscle growth, n=107) or losing body weight (Weight loss, n=107). The Muscle growth group contained a higher percentage of men, whereas the Weight loss group contained a higher percentage of women. The Muscle growth group showed significantly higher scores of nutritional knowledge and eating behaviors compared to the Weight loss group. The Muscle growth group also had a significantly higher intake of energy and protein compared to the Weight loss group. In fact, the intake of energy in the Weight loss group was lower than the estimated energy requirement (EER) for both men and women subjects. The intake of protein in the Muscle growth group was twice as much as the recommended nutrient intake (RNI). The intake of calcium in both groups was less than the RNI. In conclusion, those who exercised with the aim of increasing muscle took excess dietary protein and those who exercised with the aim of weight loss had a lower energy intake than the EER.

The objective of this study was to investigate the correlation among the measurements of the body weight and shank length at the age of 0, 4, 8, 12, 16 and 20 wk, and to investigate the regression of the final body weight at the age of 20 wk in selection on the body weight and shank length before 12 wk of age. From the simple correlation analysis, the range of correlation coefficients between body weight and shank length at the same age were 0.50~0.83 from females, and 0.57~0.85 from males over all wk of age(P＜0.01). Correlation coefficient between the body weights at hatch and 20 wk of age was 0.44(P＜0.01), but it was not significant(P＞0.05) between the shank length at hatch and body weight at 20 wk of age. The favorable regression models for the estimation of the body weight at the age of 20 wk from both body weight and shank length before 12 wk of age were the models with the independent variables of measurements at hatch and 12 wk of age($R^2$＝0.96), with the measurements at 8 and 12 wk of age($R^2$＝0.96), and with the measurements at 0, 8 and 12 wk of age ($R^2$＝0.96).
