The purpose of this study was to compare nutrient intakes, blood lipids and bone mineral density of male (n = 59) and female (n = 172) teachers according to the obesity index by percentage of body fat and age. The energy intakes of obesity group were higher than normal group in male (p < 0.05), but were not significant in female. The protein intake ratio among three energy nutrients for male was higher than female (p < 0.001), and lipid intake ratio of obesity group in female was a little higher than male that was not significant. TC, LDL, TC/HDL, risk of coronary heart disease, blood glucose and blood pressure of obesity group were higher than normal group in female (p < 0.01 ~ p < 0.001), but were little significance in male. Risk of coronary heart disease was affected by gender (p < 0.001), obesity degree (p < 0.01), age (p < 0.001), and interaction of gender and age (p < 0.001). Blood glucose was affected by obesity degree (p < 0.05), but was not affected by age. T-scores of forearm for female (= -1.42) were lower than that of male = -0.95), and T-scores of obesity group in male (= 0.12) were higher than that of normal group (= -0.33) but were not significant in female. The T-scores of forearm for female were affected by age (p < 0.05) and gender (p < 0.01), but calcaneus was not affected by gender. These results suggest lipid intake ratio should be balanced for obesity group in female. Nutritional education for treatment obesity to prevent hyperlipidemia and arteriosclerosis is necessary for obesity group and older age groups. T-scores of forearm were lower than calcaneus, so arm exercise would be especially required to prevent osteoporosis for older age women groups.

The purpose of this study was to examin height, weight and body composition nutrient intakes and serum lipids for high school girls in urban and fishing area. The subjects consisted of 78(44 fishing and 34 urban) high school girls aged in average 17.3 and 17 years. Their dietary intakes were assesed for 1 day by means of 24 hours dietary recall method. Concentrations of serum lipids, percentage of body fat and volume of total body water were measured. The mean energy intake of the subjects were 1431 ㎉ in fishing and 1659 ㎉ in urban area. The subjects in fishing area(urban) consumed 58(67) g protein, 27(36) g lipid, 459(634) mg calcium, 676(945) mg phosphorous, 11(14) mg iron, 786(574) RE retinol, 2.8(3.6) mg tocopherol, 0.9(1.0) mg thiamin, 1.2(1.1) mg riboflavin, 16.9(20.5) mg niacin and 64.1(92.8) mg ascorbic acid, respectively. Energy, calcium, iron and tocopherol intakes were lower than the Korean RDA in both girls. The mean percentage of fishing girls were 19.8% and significantly lower than 25.6% in urban. These values seem to fall in the desirable range in fishing girls, but high school girls in urban is seemed to overweight. The mean saturated fatty acid(SFA), monounsaturated fatty acid(MUFA), polyunsaturated fatty acid(PUFA) and dietary cholesterol(Chol) intakes were 7.3 g, 8.1 g, 7.2 g and 263 mg for fishing girls were 13.1 g, 12.1 g, 9.1 g and 216 mg for urban girls respectively. The fat, SFA and MUFA intakes in fishing girls were significantly lower than urban girls. The P/M/S ratio was 0.9/1.1/1 for fishing, was 0.7/0.9/1 for urban. The mean serum triglyceride(TG), total cholesterol, HDL cholesterol, LDL-cholesterol concentrations were 77.7(61.8) mg/dl, 124.5(142.3) mg/dl, 59.3(22.4) mg/dl and 49.6(107.8) mg/dl in fishing girls(urban girls), respectively. All of these values seem to fall in the desirable range but HDL-chlesterol concentrations in fishing girls were significantly higher than urban girls and LDL-cholesterol concentrations in fishing girls were significantly lower than urban girls. There were positive correlations between body fat percent and total cholesterol or LDL-cholesterol concentration : negative correlations between between body fat percent and HDL-cholesterol concentration : positive correlation between fat intake and LDL-cholesterol concentration : negative correlations between serum HDL-cholesterol concentration and fat or SFA or MUFA intakes.

This study was conducted to investigate the effect of an uncooked powdered food(UPF) on the weight loss and changes of the biochemical nutritional status for 20 overweight and 26 obese women in Iksan area. We just replaced common breakfast and dinner of the subjects with UPF. Their dietary intake status was evaluated by 24-hour recall method. Also anthropometric and biochemical measurements before and after the UPF program were estimated. The intake of energy, lipid and protein decreased and the quality of meals improved as people started to take UPF. Due to the energy loss by taking UPF, weight and body fat decreased significantly. The percentage of the body fat was high among the weight lost, from which we judged that the process of losing weight was successful. It is hard to predict whether weight loss will occur to people who are already in shape or not, but if overweight and obesity people regularly take UPF instead of other food products, we assume that UPF will help lessening the body fat. The most positive change among biochemical changes by taking UPF was the decrease of serum lipid contents. When overweight and obesity women replaced two out of three meals with UPF for 3 month period, no significant nutritional problems occurred. It seems that the 12weeks of UPF program used in this study was effective in improving anthropometric indices without producing the deficiency of iron or other susceptible nutrients.

The purpose of this study was to investigate the prevalence of obesity in urban and rural junior high school students. Height, weight, skinfold thickness and bioelectrical impedance were measured. The results obtained were summarized as follows : The average height and weight of boys were respectively 159.61cm 50.56kg and those of girls were respectively 155.88cm, 48.12kg. The percentage of obesity was respectively 6.20%, 10.22%, 5.47%, 17.15%, 14.60% for boys and 4.38%. 9.69%, 3.13%, 3.75%, 7.19% for girls by BMI, RI. OI, % body fat I, % body fat II. The rates of obesity were higher in boys than in girls, so nutritional education on obesity for boys is especially necessary. 21.09% of boys and 7.04% of girls in urban and 7.09% of boys and 7.48% of girls in rural were obese. Correlation coefficients between TC(triceps skinfold thickness + calf skinfold thickness) and BMI, RI, OI, % body fat I and % body fat II were 0.66, 0.67, 0.67, 0.77, 0.70.

Leptin receptor (OBR) is a member of the class I cytokine receptor family. It signals mainly via the JAK/STAT pathway and plays an important role in regulating body energy storage and metabolism. This study was designed to investigate the effects of the OBR gene on chicken growth and body composition. Broiler lines selected divergently for or against abdominal fat were used. Primers for the exon9-region in the OBR gene were designed using chicken genomic sequences from the public genome domain. A C/A single nucleotide polymorphism (SNP) was found and its three genotypes (AA, AB and BB) were identified in this population. The results showed that the OBR polymorphism was associated with fatness traits, such as abdominal fat weight and abdominal fat percentage. This research suggests that OBR or a linked gene has effect on fat deposition in the chicken.

Objectives: Physical inactivity is the fourth leading global risk factor for mortality, followed by obesity. The combination of these risk factors is associated with non-communicable diseases, impaired physical function, and declining mental function. The World Health Organization recommends physical activity to reduce the mortality rate. Thus, this study examined the effects on anthropometric measurements of a 12-week walking program for elderly people in Samarahan, Sarawak, Malaysia with a 7000-step goal and weekly group walking activities. Methods: A quasi-experimental study was conducted involving 109 elderly people with a body mass index (BMI) ≥25.0 kg/m². BMI, body composition, and average daily steps were measured at baseline, 6 weeks, and 12 weeks. Data were analyzed using SPSS version 26.0, and repeated-measures analysis of variance with the paired t-test for post-hoc analysis was conducted. Results: In total, 48 participants in the intervention group and 61 participants in the control group completed the study. A significant interaction was found between time and group. The post-hoc analysis showed a significant difference between pre-intervention and post-intervention (within the intervention group). The post-intervention analysis revealed an increase in the mean number of daily steps by 3571.59, with decreases in body weight (-2.20 kg), BMI (-0.94 kg/m²), body fat percentage (-3.52%), visceral fat percentage (-1.29%) and waist circumference (-2.91 cm). Skeletal muscle percentage also showed a significant increase (1.67%). Conclusions: A 12-week walking program combining a 7000-step goals with weekly group walking activities had a significant effect on the anthropometric measurements of previously inactive and overweight/obese elderly people.

Objective: We compare the effects of three different approved sources of supplemental zilpaterol on growth-performance responses and carcass characteristics of finishing lambs. Methods: Twenty four Pelibuey${\times}$Katahdin lambs ($46.75{\pm}2.43kg$) were used in a 33-day feeding trial. Lambs were fed a dry rolled corn-based finishing diet. Treatments consisted of the non-supplemental basal diet (Control) versus the basal diet supplemented with 125 mg zilpaterol/kg of diet (as fed basis) from three commercial sources marketed in Mexico: Zilmax (ZIL), Grofactor, and Zipamix. Results: Compared to controls, zilpaterol (ZH) supplementation did not affect dry matter intake (DMI), but increased carcass adjusted daily weight gain (ADG, 36.7%), gain efficiency (34.2%), and dietary net energy (26.0%), and decreased (23.4%) the ratio of observed:expected DMI. Compared to controls, supplemental ZH increased hot carcass weight (6.4%), dressing percentage (3.2%), m. longissimus thoracis (LM) area (15.6%), and shoulder muscle:fat ratio (28.7%), but decreased kidney-pelvic-heart fat, and fat thickness. Supplemental ZH increased 10.9% and 14.3% whole cut weight of loin and leg, respectively, and the proportion (as percentage of cold carcass weight) of leg (4.3%). These increases were reflected in greater forequarter and hindquarter weights. Lambs fed ZH increased (4.6%) empty body weight (EBW) and reduced (14.7%) liver/spleen weight (as g/kg EBW). Likewise, ZH supplementation tended (p = 0.08) to lower (8.9%) visceral fat. Growth performance, energetic efficiency, hot carcass weight, dressing percentage, LM area and whole cuts were not different across supplemental ZH sources. However, compared with non-supplemented controls, only ZIL appreciably decreased carcass fat distribution, including fat thickness, percentage kidney pelvic and heart fat, shoulder fat, and visceral fat. Conclusion: Supplemental ZH increases ADG, gain efficiency, carcass dressing percentage, and LM area. The magnitude of these responses was similar among ZH sources. Nevertheless, compared with non-supplemented controls, only ZIL appreciably decreases carcass fat. The basis for this is uncertain, but indicative that some practical differences in zilpaterol bio-equivalency may exist across commercial sources tested.
