Fatness and fat patterns: associations with plasma lipids and blood pressures in adults, 18 to 57 years of age.

As a part of the Fels Body Composition Study (an extension of the Fels Longitudinal Study in Yellow Springs, Ohio), the hypothesis was examined that a centripetal fat pattern, characterized by a greater proportion of trunkal than extremity adiposity, was associated independent of age and per cent body fat with levels of plasma lipids and lipoprotein cholesterols and blood pressures. A cross-sectional sample of 303 white men and women, 18 to 57 years of age, measured between September 1976 and August 1979, was selected without regard to diagnosis of hypertension, hyperlipidemia, or obesity. The degree of centripetal adipose tissue distribution was indexed by the logarithm of the ratio of the subscapular to lateral calf skinfold thicknesses.

Segregation analysis of low levels of high-density lipoprotein cholesterol in the collaborative Lipid Research Clinics Program Family Study.

Complex segregation analysis with the unified mixed model in white families from nine lipid research clinics was carried out to delineate the mode of familial transmission of plasma high-density-lipoprotein cholesterol (HDL-C). Three groups of families from the collaborative Lipid Research Clinics Program Family Study were assessed: 1,146 selected at random, 483 obtained through hypercholesterolemic probands, and 177 selected from the random sample because a number had low HDL-C, the sample sizes being 4,279, 1,807 and 735, respectively. The data were first transformed and adjusted for effects of covariates.

Multivariate analysis of lipoprotein cholesterol fractions.

Intervention and prevention of multifactorial diseases such as coronary heart disease can be effective only when the joint effects of multiple risk factors are known. This process is facilitated by multivariate analysis of correlated risk factors, such as the serum cholesterol fractions, high density lipoprotein (HDL), low density lipoprotein (LDL), and very low density lipoprotein (VLDL). Whereas evidence for genetic covariation provides focus for further refined biochemical analysis, covariation among environmental factors can point to efficacious intervention strategies.

Effects of fenofibrate on lipids, lipoproteins, and apolipoproteins in 33 subjects with primary hypercholesterolemia.

The effects of fenofibrate on lipids, lipoproteins, and apolipoproteins in 33 subjects with primary hypercholesterolemia were assessed in a 6-month parallel group study, placebo (n = 15) versus fenofibrate 300 mg/day (n = 18), followed by an open label 6-month treatment period. After stabilization on an isocaloric low fat (less than 35% total calories) diet with less than 250 mg cholesterol/day and a P/S ratio of 1, and maintenance of LDL-cholesterol (LDL-C) levels greater than or equal to 175 mg/dl, subjects received placebo for 6 weeks and were then randomized into placebo or fenofibrate groups for 6 months, followed by open label treatment for 6 months. During the 6-month double-blind period, compared to the placebo group, the treatment group had significant reductions in total cholesterol, LDL-C, total apo B, and triglyceride, and increments in HDL-cholesterol, apolipoprotein A-I and apolipoprotein A-II (P less than 0.

Effects of chlorinated drinking water on human lipid metabolism.

Atherosclerosis with its complications is the most important health problem affecting American adults. The levels of serum cholesterol, of high and low density lipoproteins, and of apolipoproteins A1, A2, and B are major risk factors for the development of atherosclerotic lesions. Animal studies suggest that chlorinated drinking water may elevate the serum cholesterol.

Dietary and other correlates of changes in total and low density lipoprotein cholesterol in hypercholesterolemic men: the lipid research clinics coronary primary prevention trial.

Correlates of changes in total (TOTAL-C) and low density lipoprotein cholesterol (LDL-C) were examined in the 3806 hypercholesterolemic men of the Lipid Research Clinics Coronary Primary Prevention Trial. These correlates included changes in weight, dietary and alcohol intake, plasma glucose and thyroxine, cigarette smoking, packet count, lipid-lowering drugs other than cholestyramine, and antihypertensive drugs. In both placebo plus diet and cholestyramine plus diet treatment groups, decreases in Quetelet index and in saturated fat and cholesterol intake and increases in polyunsaturated fat intake were consistently associated with reductions in TOTAL-C and in LDL-C.

Safety and efficacy of long-term diet and diet plus bile acid-binding resin cholesterol-lowering therapy in 73 children heterozygous for familial hypercholesterolemia.

Our specific aim was to examine the efficacy and safety of long-term cholesterol-lowering diet and bile acid-binding resin therapy in 73 children heterozygous for familial hypercholesterolemia (FH). We prospectively followed accretion of height and weight in 40 FH children for 5.8 years on diet alone and in 33 FH children for 4.

Blood lead levels and dietary calcium intake in 1- to 11-year-old children: the Second National Health and Nutrition Examination Survey, 1976 to 1980.

Whether, and to what degree, dietary calcium is inversely associated with blood lead levels was examined in 2,926 black and white children, 1 to 11 years of age, from the Second National Health and Nutrition Examination Survey (NHANES II). Blood lead levels were significantly higher in black than in white children, whereas white children had significantly higher dietary calcium intake (P less than .0001).

Role of risk factor management in progression and regression of coronary and femoral artery atherosclerosis.

The results of 3 recently completed studies usher in a new era in the treatment of coronary atherosclerosis and its sequelae. In aggregate, these results show that reductions in low density lipoprotein (LDL) cholesterol or reductions in the ratio of total to high density lipoprotein (HDL) cholesterol by either diet or drugs or both are effective in primary and secondary prevention of coronary artery disease (CAD). In the Lipid Research Clinics' Coronary Primary Prevention Trial, reducing levels of LDL cholesterol, regardless of whether the primary intervention was diet or drug, correlated with a reduction in CAD events.

Apolipoprotein A-I gene polymorphism associated with premature coronary artery disease and familial hypoalphalipoproteinemia.

Decreased plasma high-density-lipoprotein (HDL) cholesterol and apolipoprotein A-I levels have been associated with premature coronary artery disease. We identified a PstI restriction-endonuclease site flanking the human apolipoprotein A-I gene at its 3' end that is polymorphic. The absence and presence of this site, as determined by genomic blotting analysis of PstI-digested chromosomal DNA with the use of an apolipoprotein A-I gene probe, were associated with 3.

A major gene for primary hypoalphalipoproteinemia.

Sixteen kindreds were ascertained through probands clinically determined to have primary hypoalphalipoproteinemia, characterized by bottom decile high-density lipoprotein cholesterol (HDL-c), but otherwise normolipidemic. Age- and sex-adjusted, standardized HDL-c levels on 64 individuals in 14 nuclear families in which the proband was a parent were analyzed using the unified mixed model of segregation analysis as implemented in the computer program POINTER. The analysis proceeded by using the likelihood of offspring conditional on the parental phenotypes (conditional likelihood), which appears to overcome the limitation of possible heterogeneity in the selection criteria and provides an appropriate correction for the ascertainment.

Migraine in children: association with primary and familial dyslipoproteinemias.

We studied lipids and lipoprotein cholesterols in 39 children (26 boys, 13 girls) with severe migraine, to examine the hypothesis that primary and familial lipoprotein abnormalities might be associated with or predispose children to the migraine syndrome. Each of the children, 4 to 20 years of age, had severe migraine, leading to pediatric neurologic referral and therapy. Twenty-five of the 39 probands (64%) had a first degree relative with severe migraine, and 18% had a second degree relative with severe migraine.

Nonprogression of coronary artery atherosclerosis in homozygous familial hypercholesterolemia after 31 months of repetitive plasma exchange.

The effects of plasma exchange performed every two weeks for 31 months in combination with diet and drug therapy were studied in a patient with receptor-defective homozygous familial hypercholesterolemia. Coronary angiography performed three years prior to commencing plasma exchange was compared to angiography 31 months after starting the program. Comparison of the angiograms taken six years apart showed no progression of coronary atheroma in the main left coronary artery in which a 30% narrowing was originally seen.

Progeny's lipid and lipoprotein levels by parental mortality. The Lipid Research Clinics Program Prevalence Study.

Using data from Lipid Research Clinics study participants at visit 2 (3972 and 2346 adult men and women), we examined the hypothesis that parental mortality from cardiovascular disease (CVD) or cancer before age 60 predicts their adult progeny's lipid and lipoprotein levels. Weighted regression analysis was used to control for the potential effect of progeny's other CVD risk factors (age, systolic blood pressure, Quetelet index, cigarette smoking, and alcohol consumption), and to assess for the effect of progeny's parental cause-specific mortality status on progeny's lipids and lipoproteins. Nearly all of the statistically significant parent-progeny predictions were for sons.

Patterns of dyslipoproteinemia in selected North American populations. The Lipid Research Clinics Program Prevalence Study.

This article describes the assignment of dyslipoproteinemia (DLP) in several free-living North American populations and presents mean lipid and lipoprotein levels for each type. Dyslipoproteinemic phenotypes were assigned by a modified version of the National Institutes of Health (Fredrickson) phenotyping system. Criteria for assigning phenotypes included age- and sex-specific 5th and 95th percentiles for low-density lipoprotein and high-density lipoprotein cholesterol and total triglyceride, as well as other qualitative and quantitative criteria.

Dyslipoproteinemia in black participants. The Lipid Research Clinics Program Prevalence Study.

A comparison of blacks and whites 6 to 49 years old revealed striking differences between races with respect to the prevalence of various dyslipoproteinemias and mean plasma lipid levels. Compared with whites, juvenile and adult blacks of both sexes had higher mean levels of high-density lipoprotein cholesterol (HDL-C), with correspondingly higher prevalences of the hyperHDL and hypoLDL (low-density lipoprotein) phenotypes. In contrast, whites showed a much higher prevalence of type IV hyperlipoproteinemia and higher mean triglyceride levels in most age-sex groups.

Sex hormones, lipids, lipoprotein cholesterols, and apolipoproteins in normal and obese subjects: atherogenic relationships.

Our aim in the current study of 20 normal controls, 28 overweight, and 26 severely overweight (obese) subjects was to assess interrelationships of obesity, endogenous estradiol (E2) and testosterone (T), and the E2/T ratio with major independent explanatory variables for coronary heart disease (CHD), including lipids, lipoproteins, and apolipoproteins. Most of the lipid and lipoprotein variables (total, high-, low-, and very-low-density lipoprotein cholesterols) as well as apolipoproteins A1, A2, and B did not vary significantly with the presence of obesity. With increasing relative ponderosity, there were, however, increasing levels of total triglycerides and VLDL triglyceride.

The Effects of Physical Training on Blood Lipid Profiles in Adolescents With Insulin-Dependent Diabetes Mellitus.

In brief: Fourteen adolescents (eight females and six males) with insulin-dependent diabetes mellitus (IDDM) participated in a 12-week exercise program consisting of three 45-minute sessions per week. Exercise consisted of calisthenic warm-up and stretching (ten minutes), aerobic movement to music (25 minutes at 80% V o2 max), and cool-down (ten minutes). The purpose was to determine whether and to what degree such training would bring about changes in blood lipid and lipoprotein profiles in such patients.

Nonpharmacologic and pharmacologic alteration of high-density lipoprotein cholesterol: therapeutic approaches to prevention of atherosclerosis.

High-density lipoprotein (HDL) cholesterol, an independent coronary heart disease (CHD) risk factor, is inversely associated with CHD. Whether interventions to increase concentrations of HDL--particularly the HDL2, HDL3, and apolipoprotein A1 subfractions--will reduce the incidence of CHD in high-risk patients is thus an area of intense speculation. Both nonpharmacologic and pharmacologic regimens will raise HDL concentrations.

Tracking of high- and low-density-lipoprotein cholesterol from childhood to young adulthood in a single large kindred with familial hypercholesterolemia.

Tracking of high- and low-density-lipoprotein cholesterol (HDLC, LDLC) from childhood to young adulthood was assessed in 77 children and in 53 adults from a single large pedigree with familial hypercholesterolemia who were respectively less than or equal to 19 and greater than or equal to 20 years old when first studied in 1973, with reassessment in 1984. No children and only five of the adults had received LDLC lowering therapy from 1973 to 1984. The rank correlations between the 1973 and 1984 measurements for LDLC were 0.
