The influence of obesity and fat distribution on serum levels of lipoprotein and apolipoprotein was investigated in 294 Japanese junior high school children (12-13 years of age). Serum levels of low-density lipoprotein cholesterol (LDLC) (P= 0.013), triglycerides (TG) (P= 0.0006), and apolipoprotein B (apoB) (P= 0.003), and the apoB/A-I ratio (P= 0.005) were significantly higher and serum levels of high-density lipoprotein cholesterol (HDLC) (P= 0.00003) and apoA-1(P = 0.003) were significantly lower in obese boys than in non-obese boys. The serum levels of TG (P = 0.013) and the apoB/A-1 ratio (P= 0.011) were significantly higher and the serum levels of HDLC (P= 0.004) was significantly lower in obese girls than in non-obese girls. The LDLC/apoB ratio was lower in obese girls than in non-obese girls (P= 0.03). Obesity ( 20% of ideal weight) was strongly correlated with the serum levels of lipids and apolipoproteins in boys; this relationship was less clear in girls. The degree of obesity and the body mass index (BMI) were more strongly correlated with serum levels of lipids and apolipoproteins in boys than in girls. In boys, atherogenic-lipoproteins and apolipoproteins, such as LDLC and apoB, showed a stronger correlation with the thickness of the triceps skinfold, while in girls the anti-atherogenic lipoproteins and apolipoproteins, such as HDLC and apoA-1, showed a stronger correlation with both the triceps and the subscapular skinfold thicknesses. In girls the relationships between the BMI and the degree of obesity and the thickness of the subscapular skinfold (S) thickness were similar to the relationships between those parameters and the triceps skinfold (T) thickness. In boys, these parameters showed a stronger correlation with the subscapular skinfold thickness than with the triceps skinfold thickness. The correlation coefficients for the relationships between skinfold thickness and lipid and apolipoprotein levels were similar to the coefficients for the relationships between skinfold thicknesses and the severity of obesity and the BMI. The distribution of central-type fat accumulation, which is indicated by the thickness of the subscapular skinfold, the S/T ratio and S-T value, was inversely correlated with the HDLC level in both boys and girls. The degree of obesity was strongly correlated with the atherogenic lipoprotein profile in boys, in part because the subscapular skinfold thickness was strongly correlated with the degree of obesity and the BMI. In girls, the correlations between indices of central-type obesity and atherogenic lipid and apolipoprotein profiles were stronger than in boys. These data suggest that childhood obesity may be an early cardiovascular risk factor. 相似文献

This study aimed to establish reference values for serum levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) in children. The study included samples from 4,102 healthy children (2,003 boys and 2,099 girls) ages 1–18 years. The serum levels of total cholesterol, triglycerides, and HDL-C were determined using the Advia 2400 autoanalyzer. The LDL-C levels were calculated using the Friedewald equation. The mean, standard deviation, and 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentile values of the biochemical parameters for boys and girls were detected. The total cholesterol and HDL-C levels were higher among the girls than among the boys in 15- to 18-year-old group. No significant difference was found for the other serum lipid levels among any of the age groups. This study provided pediatric reference intervals for the lipid parameters for children. 相似文献

A school-based study was implemented to assess the family history of coronary heart disease (CHD) and hyperlipidemia (HL) in relation to serum lipoprotein and apolipoprotein levels. One hundred and twenty-five elementary school students (aged9–10 years) and 297 junior high school students (aged12–13 years) participated. Family history was evaluated by the following scoring method: positive family history in a parent. 2 points: in a grandparent. 1 point: and onset of CHD before age 60, 1 additional point. Family history of HL was positive in 8.2% of elementary school students, and 4.2% in junior high school students. Family history of CHD was positive in 11.5% of elementary students, and 11.0% in junior students. Family history score (FHS) for HL was related to serum total cholesterol (TC), low density lipoprotein cholesterol (LDLC), high density lipoprotein cholesterol, apolipoprotein A-T, apolipoprotein B (apoB) and lipoprotein (a) in elementary students, and to TC, LDLC, triglyceride and apoB in junior students. There was no relationship between FHS for CHD and serum lipoprotein or apolipoprotein levels in any student. The children with a positive FH of HL already demonstrated an atherogenic lipid profile while those with FH of CHD did not. which was probably because lipid profiles in children are more genetically mediated by a FH of HL than of CHD. 相似文献

Body fat deposition was measured in overweight and non-overweight children using a bioelectrical impedance method, and its relationship with serum lipids and apolipoproteins was investigated in 90 overweight children (over 120% of their ideal weight) and 241 non-overweight children aged 10–15 years in Niigata Prefecture. The results were as follows. Overweight boys had significantly higher levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), atherogenic index (AI), RLP-cholesterol (RLP-C), apoA1, apoA2, apoB, apoC2, apoC3, apoE and the ratio of apoB to apoAl than non-overweight boys. Overweight girls had significantly higher levels of TC, LDL-C, AI, remnant-like lopoprotein cholesterol (RLP-C), apoA2, apoB, apoC2, apoC3, apoE and the ratio of apoB to apoA1 than non-overweight girls. It has been reported that of all children studied 2.1% had higher levels of RLP-C than its upper limit known for adults (12 mg/dL). Of the overweight children in the present study, 4.4% had a high level of RLP-C whereas only 1.2% of non-overweight children had a high RLP-C level. No difference in the lipoprotein levels was found between overweight and non-overweight children. In both boys and girls, relative weight, body fat, skinfold thickness and body mass index (BMI) were correlated with the lipoprotein levels. Non-overweight boys whose body fat was over 20% had significantly higher levels of TC, LDL-C, apoA2, apoB, apoC2, apoE and apoB/A1 than those whose body fat was less than 20%. It was concluded that the measurement of body fat deposition, together with relative weight, was useful for detecting obesity and atherogenesity in Japanese school children. 相似文献

Hypercholesterolemia has been known to be an important factor in the development of atherosclelosis. Blood cholesterol screening and related health education in children, however, have not yet been widely practiced in Japan. From 1985 to 1990, blood samples were obtained from 5825 school children aged 6 to 14 years residing in Hisayama, Japan. The mean total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels were determined. The mean TC levels ranged from 155 to 172 mg/dL for boys and from 156 to 170 mg/dL for girls, peaking at 9 years for both sexes. The TG levels also tended to increase gradually and to peak at 11 years for both sexes. The tendency for TG levels to be higher was much clearer than in US children and adolescents. The HDL-C levels were highest at 9 years of age for both sexes and the LDL-C levels also tended to peak at 9 years of age for boys and at 8 years of age for girls. Atherogenic Indices [(TC-HDL-C)/HDL-C] ranged from 1.7 to 1.9 for boys and 1.8 to 2.0 for girls. As the cholesterol level of Japanese children would be expected to rise steadily reflecting their westernized lifestyle, preventive programes on a nationwide base including health education at school environments should be emphasized. 相似文献

Background: Due to the lack of country‐specific norms in Saudi Arabia, age‐ and gender‐specific lipid reference intervals are needed to be established for Saudi children. Methods: Blood samples were collected from 1168 children aged 6–16 years: 500 boys (43%) and 668 girls (57%), and were analyzed for cholesterol, high‐density lipoprotein (HDL) and low‐density lipoprotein (LDL). Reference intervals were established by calculating the mean and the 2.5th and 97.5th percentiles. Results: There were significant differences between boys at each Tanner stage with respect to cholesterol (P < 0.001); and HDL (P < 0.0001) but not LDL (P < 0.06) among girls. There were significant differences between boys and girls during puberty with respect to cholesterol (P < 0.0001), HDL (P < 0.0001), and LDL (P < 0.001). There was a significant positive correlation between total cholesterol levels, LDL and HDL levels at all Tanner stages in both genders. In girls, the only significant inverse correlation was at stage I (r=?0.243, P= 0.001); there was no significant correlation at other stages. Conclusions: Unlike children in other developing countries, Saudi children do not have lower serum cholesterol than their Western counterparts. These findings reflect changing dietary habits and increasing affluence in Saudi Arabia. These reference intervals may be used to aid in the early assessment of cardiovascular risk in Saudi pediatric populations. 相似文献

AIM: The objective of this study was to investigate whether the presence of small, dense lipoproteins, which are thought to be related to the metabolic syndrome caused by insulin resistance, can be predicted by routine serum lipid profiling. METHODS: The relationship between low-density lipoprotein (LDL) particle size and serum lipid levels was analysed in 284 school children (148 boys and 136 girls), aged 7 to 13 y old. LDL particle size was determined by gradient gel electrophoresis. RESULTS: The LDL particle diameter was significantly correlated with the serum levels of high-density lipoprotein cholesterol (HDL-C) (r = - 0.437, p < 0.001) and triglycerides (TG) (r = -0.432, p < 0.001), and with the atherogenic index (AI) [total cholesterol/ HDL-C] (r = -0.450, p < 0.001), while only weak correlations were observed with the serum levels of total cholesterol, apolipoprotein Al and apolipoprotein B. No significant relationship was observed between LDL particle diameter and the serum LDL-C level. CONCLUSION: The presence of small, dense LDL as a metabolic marker of lifestyle-related diseases in children seems to be reflected by a serum lipid profile characterized by an elevation in TG, a reduction in HDL-C, and a raised AI. 相似文献

In Turkish adults, the incidence of coronary artery disease (CAD) has been found to be high. However, no detailed lipid, or lipoprotein data of children are available from Turkey. The present study was designed to define the borderline lipid and lipoprotein levels of sera in 397 healthy children (aged5–14 years; 206 boys and 191 girls). Mean levels of total cholesterol (TC), triglyceride (TG), high- and low-density lipoprotein cholesterol (HDL-C and LDL-C, respectively) were found to be 150, 79, 46.7, and 87.6 mg/dL, respectively, for boys, and 152, 77.5, 46.3 and 90.5 mg/dL, respectively, for girls. Lipids and lipoproteins did not show any significant correlation with age and body mass index (BMI), except for TG in boys in whom TG levels were positively correlated with age and BMI. There were no significant differences in lipid and lipoprotein levels between boys and girls. As in the Turkish adult population, serum HDL-C levels of Turkish children were profoundly low on international comparison. Twenty-three (53%) of 43 children with low HDL-C level ( 35 mg/dL) had abnormal ratios of TC/HDL-C ( 5) and/or LDL-C/HDL-C ( 4.5), whereas only 13 (3.7%) of the remaining 354 children with a HDL-C level less than 35 mg/dL had abnormal ratios of TC/HDL-C (5) and/or LDL-C/HDL-C ( 4.5). The low levels of HDL-C in Turkish children may be associated with the high incidence of CAD in the Turkish adult population. 相似文献

Serum levels of cholesterol (C), triglycerides (TG), lipoprotein-C and apolipoproteins (apo) A-I, A-II and B were measured in 30 children with type I diabetes mellitus (16 boys, 14 girls, aged 11-14 years) and in 26 healthy controls (15 boys, 11 girls, aged 10-13 years). For 19 diabetics controls matched for age, sex and relative body weight were selected. The diabetic patients were considered to be in fair metabolic control according to HbA1 levels and glycosylated serum protein concentrations. Mean serum apo A-I, A-II and B, C, TG, low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) did not differ significantly between diabetic nondiabetic children. Very low density lipoprotein cholesterol (VLDL-C) was significantly higher in diabetic children than in controls. Serum C and LDL-C levels showed close univariate linear correlations with glycosylated serum protein (LDL-C: r = 0.53, p less than 0.01, C: r = 0.58, p less than 0.01) in diabetics. The ratio LDL/HDL-C was significantly correlated to HbA1 levels (r = 0.47, p less than 0.01). By canonical and multiple linear correlation analysis significant relations of a selected set of variables concerning the control and therapy of diabetes (serum glucose, HbA1, glycosylated serum protein, insulin dose) with a set of lipoprotein variables (C, TG, VLDL-C, HDL-C, LDL-C, apo A-I, A-II, B) could be demonstrated. From these data we conclude that significant relations between atherogenic serum lipids and lipoproteins (C, LDL-C) and the degree of metabolic control exist in diabetic children, even in the absence of marked dyslipoproteinemia.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Growth hormone (GH) affects body composition and atherogenic risk factors. Severehyperlipidemia may develop in GH-deficient adults as a consequence of continuous GHdeficiency. We investigated changes in lipid profiles in 158 Japanese children (103 boysand 55 girls) with GH deficiency who had been enrolled in the Pfizer International GrowthDatabase Japan during 3 yr of GH replacement therapy to evaluate whether GH treatment hasbeneficial effects on atherogenic risk factors. Total cholesterol (TC), high-densitylipoprotein cholesterol (HDLC), low-density lipoprotein cholesterol (LDLC) and atherogenicindex were evaluated before treatment and then once a year during treatment. The meanbaseline TC was within the normal range in both boys and girls. Seventeen (16.5%) of the103 boys and 18 (32.7%) of the 55 girls, however, had a TC level over 200 mg/dl beforetreatment. The mean TC level showed a significant decrease in girls. In a separateanalysis, patients of both sexes with a TC level > 200 mg/dl showed significantlydecreased TC. LDLC decreased significantly only in girls, while HDLC showed no change ineither sex. The atherogenic index decreased significantly in girls. GH replacement therapyin children with GH deficiency had beneficial effects on lipid metabolism and atherogenicrisk in both sexes. Early GH treatment would produce lipid metabolism benefits in thesepatients. 相似文献

ABSTRACT. Serum levels of cholesterol (C), triglycerides (TG), lipoprotein-C and apolipoproteins (apo) A-I, A-II and B were measured in 30 children with type I diabetes mellitus (16 boys, 14 girls, aged 11–14 years) and in 26 healthy controls (15 boys, 11 girls, aged 10–13 years). For 19 diabetics controls matched for age, sex and relative body weight were selected. The diabetic patients were considered to be in fair metabolic control according to HbA1 levels and glycosylated serum protein concentrations. Mean serum apo A-I, A-II and B, C, TG, low density lipoprotein cholesterol (LDL-C) and high density lipoprotein cholesterol (HDL-C) did not differ significantly between diabetic and nondiabetic children. Very low density lipoprotein cholesterol (VLDL-C) was significantly higher in diabetic children than in controls. Serum C and LDL-C levels showed close univariate linear correlations with glycosylated serum protein (LDL-C: r =0.53, p <0.01, C: r =0.58, p <0.01) in diabetics. The ratio LDL/HDL-C was significantly correlated to HbA1 levels ( r =0.47, p <0.01). By canonical and multiple linear correlation analysis significant relations of a selected set of variables concerning the control and therapy of diabetes (serum glucose, HbA1 , glycosylated serum protein, insulin dose) with a set of lipoprotein variables (C, TG, VLDL-C, HDL-C, LDL-C, apo A-I, A-II, B) could be demonstrated. From these data we conclude that significant relations between atherogenic serum lipids and lipoproteins (C, LDL-C) and the degree of metabolic control exist in diabetic children, even in the absence of marked dyslipoproteinemia. The close relation of LDL-C and total C with glycosylated serum protein in the diabetics might be due to glycosylation of LDL . 相似文献

The aim of the present study was to evaluate lipoprotein(a) distribution in children and to assess its association with lipid profile and anthropometric variables. We studied 98 children (44 girls and 54 boys) with ages ranging from 6 to 7 years, who were included in an epidemiological study on the prevalence of hypercholesterolemia in children in the province of Biscay. The following parameters were determined: weight and height, body mass index, lipoprotein(a), and lipid profile. Lipid profile included total cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, triglycerides, apolipoprotein B, and apolipoprotein A1. The mean and median serum lipoprotein(a) levels were 13.07 and 5.56 mg/dl respectively and were 11.43 and 3.92 mg/dl for boys and 15.09 and 8.32 mg/dl for girls. Lipoprotein(a) concentrations > 30 mg/dl were found in 7.4% of the boys and in 11.4% of the girls. The mean values and prevalences of lipoprotein(a) > 30 mg/dl were lower in boys than in girls but these differences were not statistically significant. A positive correlation was found between lipid profile (LDL-cholesterol, apolipoprotein B and LDL-cholesterol/HDL-cholesterol index) and lipoprotein(a) levels. When evaluating anthropometric variables, we found a statistically significant inverse correlation between weight and lipoprotein(a). In view of the cumulative effect of cardiovascular risk factors and the results of this study, we believe that lipoprotein(a) determination should be considered in children with an unfavorable lipid profile. 相似文献

AIM: To make new criteria of serum lipid levels in current Japanese children using the large nationwide data provided from Japan Association of Health Service for the analysis. METHODS: The subjects were schoolchildren who received screening and care programs for lifestyle related diseases since 1993-1999. Serum total cholesterol (TC), high-density lipoprotein cholesterol (HDLC) and triglyceride (TG) levels were measured, and low-density lipoprotein cholesterol (LDLC) levels were calculated. Serum lipid levels were analyzed by age and sex. For each serum lipid, we extracted age- and sex-specific group which the mean value was not statistically different from that in 1999 by Student's t-test analysis. RESULTS: The level below the 75th percentile was defined to be acceptable, from the 75th to 95th to be borderline and over the 95th to be high in TC/LDLC. The level below the fifth percentile in HDLC was defined to be low and the level over the 95th percentile in TG to be high. Therefore, TC level was categorized as follows: acceptable < 190 mg/dL; borderline 190-219 mg/dL; and high > 220 mg/dL. The LDLC level was also categorized into: acceptable < 110 mg/dL; borderline 110-139 mg/dL; and high > 140 mg/dL. The cut-off value in TG was determined to be 140 mg/dL and in HDLC was 40 mg/dL. CONCLUSIONS: This new criteria should prove valuable in health strategies for rational prevention and intervention in children. It should be emphasized to provide some intervention for Japanese children immediately. 相似文献

Sixty eight children born in 1977 who were taking part in an unrelated study of childhood asthma were selected to have their serum cholesterol concentrations measured at birth, and at 4 months and 1, 2, 3, 4, 5, and 11 years of age. Concentrations of high density lipoprotein were measured at 5 and 11 years. Cholesterol values increased rapidly from birth and plateaued at 1 year. There was a further small rise just before puberty. Tracking of values was seen after the age of 1 year, but did not become established until 4 years of age. The cholesterol concentrations in girls were marginally higher than those in boys. The mean (SD) values of cholesterol (mmol/l) for boys were: at birth, 1.7 (0.4); at 1 year, 3.9 (0.9); at 5 years, 5.2 (1.9); and at 11 years, 5.0 (0.7). For girls the corresponding figures were; at birth, 1.9 (0.6); at 1 year, 4.7 (1.0); at 5 years, 4.6 (0.7); and at 11 years, 5.1 (0.7). The mean (SD) high density lipoprotein concentrations (mmol/l) for boys were: at 5, 1.16 (0.35) and at 11, 1.51 (0.23). For girls they were 1.28 (0.30) and 1.56 (0.27), respectively. The serum cholesterol concentrations in these children were high compared with published figures from north America. 相似文献

BACKGROUND: The aim of this cross-sectional study was to record the prevalence of underweight, overweight and obesity in primary school children living in Istanbul and to examine the relationship between increased body weight and certain cardiovascular disease (CVD) risk factors. METHODS: A total of 510 randomly selected children aged 12 and 13 years of age (257 boys, 253 girls) were examined. Information regarding anthropometrical indices, energy and macronutrient intake, physical activity, physical fitness and lipid profile were collected. Classification of children in overweight and obese subgroups was based on the cut-off points proposed by Cole et al. RESULTS: The prevalence of underweight, overweight and obesity was found to be 15.3%, 10.6% and 1.6%, respectively. Both overweight boys and girls were found to have lower physical fitness compared to their normal-weight counterparts, but no difference was observed for energy and macronutrient intake. Overweight boys were found to have higher total cholesterol (P < 0.001), low-density lipoprotein cholesterol (P < 0.01), triglycerides (P < 0.01) and total cholesterol/high-density lipoprotein cholesterol (HDL-C) ratio (P < 0.05) compared to their normal-weight counterparts, while overweight girls were found to have lower HDL-C (P < 0.05) compared to their normal-weight peers. CONCLUSIONS: Underweight and overweight coexisted in the current population. Increased body weight was accompanied by unfavorable lipid profiles and lower fitness levels. Consequently, there is an emergent need for early identification and understanding of behavioral and physiological variables related to obesity and CVD, so that appropriate interventions can be targeted to children who are at risk for adult onset of these diseases. 相似文献

Background: Cardiovascular disease (CVD) risk factors are associated with body mass index z‐score (BMISD) and/or insulin resistance (IR). However, the correlation between adverse levels of these risk factors and BMISD, and the effect of IR on these associations are not fully understood in children. The aim of this study was to evaluate the association between adverse levels of CVD risk factors and BMISD, and the effect of IR on these associations in schoolchildren. Methods: Conventional CVD risk factors, C‐reactive protein (CRP), uric acid (UA) and adiponectin were determined in 757 boys and 494 girls aged between 7 and 12 years. IR was assessed by the homeostasis model approximation index. Results: BMISD were linearly associated with relative risks having adverse levels of all factors, except for glucose and low‐density lipoprotein cholesterol (LDL‐C) in boys, and except for glucose, LDL‐C and adiponectin in girls (P < 0.01–0.001). These associations were weakened after adjustment for IR, but still significant in cases of UA and CRP in boys and UA, high‐density lipoprotein cholesterol and CRP in girls (P < 0.01–0.001). Conclusion: The relative risk of having adverse levels of most CVD risk factors in school children increased across the entire range of BMISD. IR contributed to most of these relative risks, but BMISD itself also contributed to these relative risks. To prevent future development of CVD, it might be important for schoolchildren to maintain BMISD within normal range. However, in cases of hyper LDL‐cholesterolemia, we should consider causes other than BMISD. 相似文献

OBJECTIVE: To elucidate associations of age and sex with serum cholesterol and triglyceride levels and to provide for the first time percentile distribution data for pediatric lipids. PARTICIPANTS AND METHODS: A high sample of 7767 (3980 boys, 3787 girls) fasting schoolchildren, 6 to 14 years of age, were studied in Athens, Greece. RESULTS: The mean cholesterol ranged from 157 to 174 mg/dL for boys and from 158 to 172 mg/dL for girls peaking at 9 years of age for both sexes. Triglyceride levels also tended to increase gradually and to peak at 11 years of age for both sexes. The high-density lipoprotein cholesterol levels were highest at 9 years of age for both sexes and the low-density lipoprotein cholesterol levels also tended to peak at 9 years of age for boys and at 8 years of age for girls. Atherogenic indices ranged from 1.54 to 1.68 for boys and 1. 51 to 1.85 for girls. CONCLUSION: According to these findings, it could be suggested that diet changes in the Greek population, especially in children and adolescents, living in big cities is significantly influencing their total cholesterol profiles throughout the last 10 years. 相似文献

In order to determine the age and sex dependency of some of the major risk factors for coronary heart disease during the period of sexual maturation a five-year longitudinal study was carried out on 105 boys and 133 girls living in Plzen, Czechoslovakia. Serum cholesterol was significantly elevated in 13-year-old girls (p less than 0.01), while no statistically significant sex-related differences in total and lipoprotein cholesterol and apolipoprotein A-I and apolipoprotein B levels were found in other age groups during the period of follow-up. In boys the total cholesterol showed a constant and statistically significant decrease (p less than 0.01) between the ages 11 to 13 years, but tended to rise during the last two years of study. In girls, serum cholesterol decreased significantly between the ages 11 to 15 years (p less than 0.05). A statistically significant decrease in pre-beta cholesterol was found in girls during puberty (p less than 0.05). The changes in beta lipoprotein cholesterol were similar to those for total cholesterol. The apolipoprotein A-I concentration decreased significantly between 11 and 15 years in boys (p less than 0.05), while it underwent no substantial change in girls. The apolipoprotein B level decreased permanently and significantly (p less than 0.05) during the 5-year period in girls. In boys, the concentration of this protein decreased between 11 and 14 years and increased during the 15th year when a value significantly higher than that for girls was attained (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Aim: The effects of gender on the association between apolipoprotein E genotype and plasma lipid levels remain unclear in children. The aim of the present work was to evaluate these gender differences in a large population-based sample of 6-7-y-old children, free of the effects of sex hormones.
Methods: Lipid levels and apo E genotypes were studied in a sample of 1255 (631 M, 624 F) Caucasian schoolchildren, aged 6-7 (mean age, 6.7) y in Spain.
Results: A significant effect of the apo E genotype on plasma total cholesterol, LDL-C (low-density lipoprotein cholesterol) and apo B levels was observed. Taking the homozygous ε3 ε3 genotype as reference, the presence of the ε2 and ε4 alleles is associated with substantially lower and higher plasma levels, respectively, of these variables. It was found that the effect of the apo E polymorphism on total cholesterol, LDL-C and particularly on apo B levels was greater in girls than in boys.
Conclusion : At this prepubertal age, the influence of the apo E genotype on total cholesterol, LDL-C and apo B levels is more evident in girls than in boys. This difference in effect is not due to sex hormones. In our opinion, the earlier increase in adrenal androgens in girls than in boys at this age related to pubertal maturation could be responsible for these differences. 相似文献
