The major goals of the poultry industry are to increase the carcass yield and to reduce carcass fatness, mainly the abdominal fat pad. The increase in poultry meat consumption has guided the selection process toward fast-growing broilers with a reduced feed conversion ratio. Intensive selection has led to great improvements in economic traits such as body weight gain, feed efficiency, and breast yield to meet the demands of consumers, but modern commercial chickens exhibit excessive fat accumulation in the abdomen area. However, dietary composition and feeding strategies may offer practical and efficient solutions for reducing body fat deposition in modern poultry strains. Thus, the regulation of lipid metabolism to reduce the abdominal fat content based on dietary composition and feeding strategy, as well as elucidating their effects on the key enzymes associated with lipid metabolism, could facilitate the production of lean meat and help to understand the fat-lowering effects of diet and different feeding strategies.

Purpose : We investigated the correlation between body composition and lung function in healthy adults. Methods : This study included 204 healthy adults in whom all measurements were obtained once, and all data were analyzed using the SPSS software for Windows, version 22.0. Pearson's correlation analysis was performed to determine the correlation between body composition (represented by the total body water, protein mass, soft lean mass, mineral mass, basal metabolic rate, fat-free mass, skeletal muscle mass, and body fat percentage) and lung function (represented by the forced vital capacity [FVC], forced expiratory volume in 1 second [FEV₁], the FEV₁/FVC ratio, maximum voluntary ventilation [MVV], maximum expiratory pressure [MEP], and the maximum inspiratory pressure [MIP]). All measurements were obtained by two investigators to improve reliability. A significance level of α=.05 was used to verify statistical significance. Results : Among the lung function measurements obtained in both men and women, the FVC, FEV₁, MVV, and MIP were positively correlated with the total body water, protein mass, soft lean mass, mineral mass, basal metabolic rate, fat-free mass, and skeletal muscle mass in men (p<.05). The FEV₁/FVC ratio was negatively correlated with the total body water, soft lean mass, mineral mass, basal metabolic rate, fat-free mass and the body fat percentage (p<.05). Notably, the FVC, FEV₁, and MVV were positively correlated with the total body water, protein mass, soft lean mass, mineral mass, basal metabolic rate, fat-free mass, and skeletal muscle mass in women (p<.05). Conclusion : This study showed a significant correlation between body composition and lung function in healthy adults. In combination with future studies on lung function, our results can provide objective evidence regarding the importance of prevention of lung disease, and our data can be utilized in rehabilitation programs for patients with respiratory diseases.

This study examined the age-related patterns in body composition cross-sectionally using Segmental bioelectrical impedance analysis(SBIA), specifically its two components, lean body mass(LBM) and body fat mass, in 1,452 men and 1,436 women with an age range of 19 to over 70 years . Mean height of male subjects was 174.1cm at peak in early 20's and was decreased continuously 0.2-0.3 cm every year. Mean weight was greatest between late 20's and 40's, and was decreased quickly in 70's. Body fat mass was increased steadily before 30's and remained thereafter. Because decreasing lean body mass (LBM), percentage of body fat(PBF) increased continuously with aging. Mean height of female subjects was 161.7 cm at peak in 20's and was decreased steadily around 0.2 cm every year and thus an individual's height was decreased approximately 10 cm in their life cycle. Body weight was increased steadily until 50's and then was decreased. Body fat mass was increased continuously and LBM remained constant and thus PBF was increased steadily with aging. SBIA can be used to compare body composition between genders and between ages. In future studies, SBIA could be applied widely to evaluate variations of body composition in subjects with different nutritional problems.

To study the correlation between body composition values and practice of the Standard Guideline for Korean Dietary Life, a nationwide cross-sectional survey was conducted with 378 female college students living in four Korean cities in December 2005. Among the student subjects, 98 were analyzed for body fat mass, percent body fat, waist-hip ratio(WHR), body mass index(BMI) and obesity degree using Inbody 3.0(Biospace Co, Seoul, Korea). Percent body fat was at a high level of 54.1 %, WHR was at a high level of 58.2% and BMI was at a high level of 41.8%. However, both weight and body fat were below normal at 79.5% and 77.6%, respectively. Percent body fat, WHR, and BMI were slightly negatively correlated with vegetable consumption, but slightly positively correlated with beer intake. WHR > 0.8 was significantly negatively correlated with exercise. Standard Guideline for Korean Dietary Life was practiced to and above normal level by 64.6% of the female college students. However, female college students who are within the normal range of body composition value should notice that obesity will relate to abdominal or visceral fat on their body.

The fat content, fatty acid composition, trans fatty acid content and triacylglycerol (TAG) composition of 22 chocolates (domestics 8, foreigns 14) collected from the Korea distribution markets were investigated. The crude fat was extracted by acid hydrolysis method and analyzed by gas chromatography (GC) and reversed-phase HPLC for fatty acid and TAG compositions, respectively. The crude fat content of all chocolates varied between 30.11% and 49.59%. The major fatty acids in most of the chocolates were palmitic acid (19.36~31.15 wt%), stearic acid (5.11~36.32 wt%) and oleic acid (18.77~36.68 wt%). Whereas lauric acid (approximately 35.43 wt%) was detected in chocolate fat of sample No. 18. High oleic acid content was observed for the sn-2 position fatty acid with a range from 64.91% to 86.93%. Trans fatty acid contents in domestic chocolates (sample No. 1~8) and foreign chocolates (sample No. 9~22) were 0.03~0.59 wt% (0.01~0.19 g/100g chocolate) and 0.05~6.32 wt% (0.02~1.99 g/100g chocolate), respectively. In TAG composition, TAGs such as POP/PPO(1,3(2)-palmitoyl-2(3)-oleoyl glycerol, PN=48), POS/PSO(palmitoyl-oleoyl-stearoyl glycerol or palmitoyl-stearoyl-oleoyl glycerol, PN=50), SOS/SSO(1,3(2)-stearoyl-2(3)-oleoyl glycerol, PN=50) were mainly detected in most of the chocolates. The peaks of TAG with low PN (ex, 32-34, 36-38, and 40-42) were detected in No. 18 chocolate fat because of containing short chain fatty acid such as lauric acid.

The aim of this study was to investigate influence of body build on body composition, energy metabolic state and insulin concentration of blood. 29 male athletes and 36 male non-athletic students were recruited for the study. Anthropometry including chest depth and breadth, fat mass, fat fee mass, tricep skinfold thickness were measured. fasting glucose, lactate, triglyceride, fee fatty acid, and insulin concentration in serum were measured . Body build was assessed using metric index, which calculated by regression equations of Mohr and Greil. The athletic and non-athletic students were allocated to 3 body build, that is leptomorph, mesomorph, and pyknomorph. Resting metabolic rate was calculated. Respiratory quotient was determined through ratio of measured VO$_2$, and V$CO_2$. Most non-athletes have a leptomorphic body build, in contrast to athletes mesomorphic type. The body build type influenced body composition differently between non-athletic group and athletic group. Weight, body mass index, body fat mass and fat mass proportion (%), and fat-free mass increased from leptomorph to pyknormorph in non-athletic group. Pyknormorphic athletes have a significant higher body mass index, fat mass, fat free mass than other body build type. Serum glucose, triglyceride, lactate, insulin showed significant differences only in non-athletic group between leptomorph and mesomorph. RMR increased significantly from leptomorph to mesomorph in non-athletes. There was no significant difference of RQ among 3 body build types in both athletes and non-athletes. This study gives a coherent data on body build and body composition for athletes and non-athletes students. The influence of body builds on energy metabolic status of serum was different between athletes and non-athletes.
