Growth and Bone Mineral Accretion During Puberty in Chinese Girls: A Five-Year Longitudinal Study,,

JOURNAL OF BONE AND MINERAL RESEARCH, Issue 2 2008
Kun Zhu
Abstract There are few longitudinal data on bone development during puberty in children with low calcium intake. This 5-yr longitudinal study showed that, in Chinese girls, the mean apparent calcium retention efficiency during puberty was 40.9%, PHV occurred at 3,0 yr before menarche, and peak bone mineral accretion occurred 1 yr later than PHV. Chinese girls have high calcium retention efficiency during puberty. Introduction: There are few longitudinal data on bone development during puberty in children with low dietary calcium intake. The aim of this study was to examine the rate of growth and bone mineral accretion and study the predictors of total body BMC during puberty in a 5-yr longitudinal study with Chinese girls. Materials and Methods: Ninety-two girls, 9.5,10.5 yr of age at baseline, from the unsupplemented control group of a school milk intervention trial were included in this analysis. Data on anthropometric measurements, total body BMC as assessed by DXA, and calcium intake as assessed by a 3-day food record were obtained at baseline and 1, 2, 4, and 5 yr. Results: The mean age of menarche was 12.1 ± 1.0 yr. The mean annual rate of bone mineral accretion was 197.4 g/yr during the follow-up period, representing a calcium accretion rate of 162.3 mg/d. This calcium retention rate and the average dietary calcium intake of 444.1 mg/d gave an apparent calcium retention efficiency of 40.9%. Peak height velocity (PHV) occurred at 3,0 yr before menarche. Peak bone mineral accretion occurred 1 yr later than PHV. There was a decrease in size-corrected BMD in the year before menarche. In the linear mixed-effects model analysis containing body size and lifestyle factors, we found that height, body weight, and calcium intake were significant independent predictors of total body BMC. Conclusions: Chinese girls with low habitual dietary calcium intake have high calcium retention efficiency during puberty. Because calcium intake is a significant predictor of total body BMC, increasing dietary calcium intake may have beneficial effects on bone mineral accretion in these girls. [source]

Acute myeloid leukaemia with giant granules: association with t(10; 11)(p13; q14) and disseminated intravascular coagulation

INTERNATIONAL JOURNAL OF LABORATORY HEMATOLOGY, Issue 5 2000
S.K. Ma
Summary A 16-year-old Chinese girl presented with AML-M5a. A bone marrow examination showed that the myeloblasts which were overwhelming the marrow contained giant granules (pseudo-Chediak,Higashi anomaly). Her karyotype showed a rare translocation t(10; 11)(p13; q14). Molecular delineation of the translocation breakpoints was not possible. Nonetheless, this case further demonstrates the morphological and phenotypic heterogeneity of acute leukaemia with this translocation. In this girl it was associated with disseminated intravascular coagulation. [source]

School-Age Adopted Chinese Girls' Behavioral Adjustment, Academic Performance, and Social Skills: Longitudinal Results

Longitudinal data on 177 school-age adopted Chinese girls (Time 1: mean age = 8.92 years, SD = 1.76; Time 2: mean age = 11.18 years, SD = 1.79) were analyzed to determine their long-term outcomes in behavioral adjustment, academic performance (measured with the Child Behavior Checklist/6,18), and social skills (measured with the Social Skills Rating System) and how these outcomes were related to preadoption adversity. More than 90% of the girls were adopted at 24 months or younger (M = 19.25, SD = 21.67). Results revealed that over a 2-year period, there was a moderate to strong stability in the children's behavioral adjustment and academic performance. However, there was a significant increase in the number of children with deviant internalizing problems. At both times, higher degrees of preadoption adversity were related to more internalizing problems and poorer academic performance. Children who were adopted at older ages had poorer academic performance. Children who were older had a lower level of assertion and a higher level of responsibility. Children's attention problems at Time 1 mediated the effect of preadoption adversity on academic performance at Time 2. [source]
