Body fat percentile curves for Korean children and adolescents: a data from the Korea National Health and Nutrition Examination Survey 2009-2010.

A valid assessment of obesity in children and adolescents is important due to significant change in body composition during growth. This study aimed to develop percentile curves of body fat and fat free mass using the Lambda, Mu, and Sigma method, and to examine the relationship among body mass index (BMI), fat mass and fat free mass in Korean children and adolescents, using the Korea National Health and Nutrition Examination Survey (KNHANES) 2009-2010. The study subjects were 834 for boys and 745 for girls aged between 10 and 18 yr.

The effect of a healthy school tuck shop program on the access of students to healthy foods.

The objective of this study was to evaluate the effect of a healthy school tuck shop program, developed as a way of creating a healthy and nutritional school environment, on students' access to healthy foods. Five middle schools and four high schools (775 students) participated in the healthy school tuck shop program, and nine schools (1,282 students) were selected as the control group. The intervention program included restriction of unhealthy foods sold in tuck shops, provision of various fruits, and indirect nutritional education with promotion of healthy food products.

The association of carbohydrate intake, glycemic load, glycemic index, and selected rice foods with breast cancer risk: a case-control study in South Korea.

Despite carbohydrate hypothesis related to breast cancer development, the inter-relationships of carbohydrate measures with risk of breast cancer are unclear. We evaluated the association between the risk of breast cancer and total carbohydrate intake, glycemic load, and glycemic index, and types of rice in a hospital-based case-control study. Cases were 362 women aged 30-65 years old who were histologically confirmed to have breast cancer.

Cross-sectional relationship between dietary carbohydrate, glycaemic index, glycaemic load and risk of the metabolic syndrome in a Korean population.

Little is known about the effect of dietary carbohydrate, glycaemic index (GI) and glycaemic load (GL) on the risk of the metabolic syndrome, especially in populations with white rice as the staple food. The study examined the cross-sectional relationship between carbohydrate, GI, GL and risk of the metabolic syndrome. There were a total of 910 middle-aged Korean adults.
