Factors Related to Calceneal Broadband Ultrasound Attenuation, Anthropometric Indexes and Nutrient Intakes among Elementary School Children in Chungnam: Ye Jung Kim, Yoon Jeong Choi, Hee Seon Kim; Korean J Community Nutr 2013;18(4):312-323.

Variables affecting bone heath of growing children were analyzed among forty nine 10-12 year old elementary students in three rural regions of north west Chungnam area. Information on age of the parents, duration of breast feeding and birth weight were collected from the guardians of the participants and nutrient intake and diet quality were assessed by average of three-day food records of participants with the help of dietitians. Bone health status was measured by calceneal broadband ultrasound attenuation (BUA) using quantitative ultrasound (QUS). Results showed that anthropometic indexes and nutrient intake levels were not different between boys and girls. However, iron intake was significantly lower in girls than in boys. Girls after menarche showed lower intake levels for thiamin, riboflavin, pyridoxine and niacin than girls before menarche. z-scores of BMI were lower than -1 and higher than +1 showed shorter breast feeding period than others but the difference was statistically non-significant. Overall, the subjects did not consume enough s of calcium, vitamin C and folic acid. Zinc intake and BMI were the most significant factors affecting BUA by the results of backward elimination in multiple regression models. Phosphorous and beta-carotene intakes showed significant negative relation with BUA. This study showed that children living in the rural area of Chungnam need extra care to keep their health and nutrient intakes especially for the nutrients known to affect growth. Tailored nutrition education needs to be more focused on the improvement of bone health status of children.

The Association between Changes in Food and Nutrient Intakes and Changes in Bone Metabolic Indicators in Postmenopausal Women with Osteopenia after a 12-week Intervention of Nutrition Education and Aerobic Exercise: Seo Jin Kim, Suh Jung Kang, Yoon Jung Park, Ji Yun Hwang; Korean J Community Nutr 2013;18(3):213-222.

Few studies investigated the effects of nutrition education and exercises in women with osteopenia. This study examined the relationship between changes in dietary intakes and changes in indicators related to bone health in postmenopausal women with osteopenia (-2.5 < or = T-score < or = 1) after a 12-week intervention. Thirty-one postmenopausal women aged > 50 years residing in Seoul were recruited and participated in nutritional education regarding bone health and general nutrition practices and aerobic exercises (three times a week; 60 min per session). Twenty-five subjects completed the study and were eligible for the analysis. Bone mineral density (BMD) at femoral neck was measured by dual energy x-ray absorptiometry. Serum calcium, osteocalcin, and intact parathyroid hormone (PTH) were also measured. Dietary intake was estimated by using a one-day 24 recall by a clinical dietitian. After 12 weeks, meat consumption increased (P = 0.028) but vegetable intake decreased (P = 0.005). Intakes of animal protein (P = 0.024), vitamin B1 (P = 0.012) and vitamin B2 (P = 0.047) increased, and sodium intake decreased (P = 0.033). Intact PTH (P = 0.002) decreased and osteocalcin (P = 0.000) increased, however, BMD decreased (P = 0.000). Changes in mushroom consumption were positively correlated with femoral neck BMD (r = 0.673, P = 0.003). Changes in animal iron intake were negatively correlated with intact PTH (r = -0.488, P = 0.013) but were positively correlated with osteocalcin (r = 0.541, P = 0.005). These results suggested that the association between animal iron intake and biochemical markers of bone turnover may play an important role in bone metabolism. Further studies are needed to shed light on complicated mechanisms of diet, hormonal levels of bone metabolism, and bone density.

Effects of Body Composition and Nutrients Intake on the Calcaneal Broadband Ultrasound Attenuation in College Students: Eun Joo Jea, Kwang Eui Byoun, Jung Eun Youn, Byung Kook Lee, Hee Seon Kim; Korean J Community Nutr 2009;14(5):590-599. Published online October 31, 2009

Abstract PDF: The purpose of this study was to analyze the relationship of nutritional status measured by the body composition and dietary nutrients intakes with calcaneal broadband ultrasound attenuation in college students. Total of 886 (462 male and 424 female) students who received health examination in May 2007 participated in this research.Participants bone status was measured by a quantitative ultrasound method and t-score was calculated via WHO guideline. For body composition measurements, body fat, height and weight were measured and BMI was calculated. Dietary data were collected by a 24-hour recall method. Based on Asia-Pacific standard of WHO, BMI was divided into 3 groups; UW (BMI<18.5), NW + OW (18.5< or =BMI<25) and Obese group (25< or =BMI). Among male students, 2.4% belong to the UW group, 45.0% to the NW+OW group and 52.6% belong to the obese group, while 10.4% of female students belong to the UW group, 71.9% to the NW + OW group and 17.7% of female students belong to the Obese group. Differences among male and female students were statistically significant (p<0.001). Students with higher BMI showed significantly higher bone health status. Male students did not show any significant differences in nutrients intakes by BMI groups while female students showed the higher intakes of energy, protein, pyridoxin, phosphorus, iron and zinc among NW + OW group than other groups (p < 0.05). The qualitative and quantitative evaluation of diet by BMI groups did not show any significant differences in both male and female students. The result of the multiple regression analyses showed that the body fat and bone status was negatively related while energy intake was positively related with the bone status. These results revealed that bone health status was positively affected by BMI but not by body fat. In conclusion, among those who are at their twenties, the period when the bone density becomes maximized, body fat may negatively affect bone health unlike during other life cycle stages.
