ABSTRACT
Objective. To develop a height and weight based equation to estimate total body water (TBW) in Sri Lankan children. Methods. Cross sectional descriptive study done involving 5-15 year old healthy children. Height and weight were measured. TBW was assessed using isotope dilution method (D2O) and fat free mass (FFM) calculated. Multiple regression analysis was used to develop prediction equation and validated using PRESS statistical technique. Height, weight and sex code (male=1; female=0) were used as prediction variables. Results. This study provides height and weight equation for the prediction of TBW in Sri Lankan children. To the best of our knowledge there are no published height weight prediction equations validated on South Asian populations. Conclusion. Results of this study need to be affirmed by more studies on other closely related populations by using multicomponent body composition.

Objective To investigate the levels of serum retinol-binding protein 4 (RBP4 )and related factors in type 2 diabetic patients. Methods Eighty type 2 diabetic and patients 30 non-diabetic subjects were recruited into obese-diabetic group [body mass index (BMI) 1525 kg/m~2],normal-weighted diabetic group(BMI < 25 kg/m~2)and control group(BMI < 25 kg/m~2). Serum adiponectin(APN), RBP4 and hemoglobin A_1c (HbA_1c)triacylglycerol (TG),total cholesterol (TC).high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C)and were measured on fasting samples. BMI, waist/hips girth ratio (WHR) and insulin resistance index (HOMA-IR) were calculated. The correlation between RBP4 and other factors was analyzed. Results The concentration of RBP4 was significantly increased in obese-diabetic group and normal-weighted diabetic group compared with that in control group [ (30.02 ± 5.32), (20.10 ± 5.45), (12.02 ± 3.45) mg/L] (P < 0.01). The concentration of RBP4 was higher in obese-diabetic group than that in normalweighted diabetic group (P < 0.01). Univariate analysis showed serum RBP4 was positively associated with TG,BMI,FBG, WHR,FINS,HOMA-IR and negatively associated with APN (r = 0.225, 0.697, 0.323,0.557, 0.272, 0.461, -0.398). Conclusions The concentration of RBP4 is significantly higher in type 2 diabetic patients compared with that in normal subjects. RBP4 possibly plays an important role in the insulin resistance and the occurrence and development of type 2 diabetes.
ABSTRACT
Se estudiaron 130 madres y sus recién nacidos prematuros con su correspondiente grupo control, nacidos en el Hospital Ginecoobstétrico Provincial Docente "Justo Legón Padilla", de Pinar del Río, desde febrero hasta julio de 1998, con el objetivo de analizar algunos factores perinatales relacionados con la prematuridad. Se analizaron las variables: edad materna, paridad, peso al inicio del embarazo, talla materna, período intergenésico, edad gestacional, oligoamnios, hipertensión arterial materna y sexo del niño. Se demostró que la edad materna inferior a 17 años, la baja talla materna, el oligoamnio, la sepsis ovular y el período intergenésico de más de 5 años tuvieron resultados significativos para el nacimiento de pretérminos.
130 mothers and their premature infants with their corresponding control group delivered at "Justo Legón Padilla" Provincial Gynecoobstetric Teaching Hospital, in Pinar del Río, from February to July, 1998, were studied aimed at analyzing some perinatal factors connected with prematurity. The following variables were analyzed: maternal age, parity, weight at the beginning of pregnancy, maternal height, intergenesic period, gestational age, oligohydramnios, maternal hypertension and sex of the child. It was proved that maternal age under 17, low maternal height, the oligohydramnios, vulvar sepsis and the intergenesic period of more than 5 years had significant results for the birth of preterm infants.
ABSTRACT
Objective To analyze the bone mineral density(BMD)and the correlated influence factors ingirls. Methods BMD and partial physical development variables of 714 girls, aged 9 to 16, were examined in Guangdong and Guangxi province and a questionnaire was administered to all subjects to determine their milk intake, physical activity, menarche, and regularity of menstruation. Results BMD in girls increased by 4.4% at age of 9～12, increased by 6.0% at age of 12～14, and increased by 2.5% at age of 14～16. Compared with girls having less than six-hour outdoor exercise, those having more than six-hour outdoor exercise revealed higher BMD levels (P200ml/day) might be effective for promoting BMD of girls during puberty.
ABSTRACT
Body weight and height of 10,672 adults (male 6534, female 4318) aged from 18 to over 46 including various kinds of job were investigated in north district of China. The body weight and height were measured by conventional method. All the subjects were divided into three aged groups (18-25, 26-45, over 46) in both sexes respectivly. The correlation regression between height and weight was calculated and significance test of regression coefficient was made.The results showed that the positive correlation was seen between the height and weight in each aged group. There were significant differences between all of aged groups in regression coefficient significance tests, except between 18-25 and 26-45 aged group in female. According to theory of normal distribution, the five types of body were defined in term of mean of height (X) and standard deviation (Sx), namely tallest, taller, middle, lower, lowest. The average of body weight corresponding to height was calculated by regression equation in each group. Meanwhile, standard error (Sy) and 95% distribution range of individual value was calculated in regression line. As mentioned above body weight was divided into five classes (overweight, upper middle, middle, lower middle, underweight). The normal value established in the survey can be used for estimation of nutritional status of adult in north China.
ABSTRACT
Body weight, height, weight index as well as obesity incidence of 4780 people (male 3216, female 1564) aged from 20 to 78 including various kinds of job were investigated in Fusan district in Shandong province. The body weight and height were measured by conventional method. The weight indexwas estimated in terms of the value of weight(kg)/height(cm)2 ? 100. The correlationregression between sex, age, height and weight was calculated as well.The result showed that the average weight index ranging from 0.1933 to 0.2525 in males and 0.1951 to 0-2563 in famales was noticed. Accordingly, the incidence of overweight and obesity was 7.71% and 8.33% in males and 6.96% and 4.73% in females respectively. The correlation coefficients between weight and age (r = 0.9838 within 20-35 in age in males, r = 0.9846 within 20-50 in age in famales), and between weight and height (r = 0.9798 within 144-180cm in males, r = 0.8595 within 140-170cm in females) were highly significant.The data mentioned above were also discussed briefly.
