Borderline Total Cholesterol Research Articles

The potential benefits of extra screening for glycated haemoglobin, total cholesterol and low-density lipoprotein cholesterol on donor health management and retention.

An extra health screening, including glycated haemoglobin (HbA1c), total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C), was initiated for regular donors aged over 40 in Taiwan in November 2015. This study aimed to determine its benefits on donor health management and retention. A stratified random mail survey was conducted among donors who received HbA1c, TC and LDL-C screening between November 2015 and June 2017 to investigate their awareness of the screening, medical histories and post-screening behaviours. Their subsequent screening results and donation records from 3 years before and after the initial screening were obtained up to December 2021. In total, 2070 donors participated in the mail survey, with participation rates ranging 15.7%-23.2% across study groups. The screening newly detected hyperglycaemia in 1.6% (95% confidence interval [CI]: 1.2%-2.0%) and hyperlipidaemia in 1.0% (95% CI: 0.7%-1.4%) of participants, with 42.7% (95% CI: 40.3%-45.2%) of participants unaware of the screening. Participants with initially abnormal or borderline TC or LDL-C results showed significant decreases in the subsequent screening (all p values<0.05). No difference was found in participants' awareness of the screening. However, those who sought medical consultation or made specific lifestyle changes tended to show greater improvements. Awareness of the screening was associated with increased whole blood donations and donated units. The extra health screening has limited benefits for donor health management without additional interventions, but it may motivate donors to donate more frequently. Raising donors' awareness of the screening is also crucial to maximize its benefits.

The Effect of Organic Vegetable Mixed Juice on Blood Circulation and Intestine Flora: Randomized, Double-Blinded, Placebo-Controlled Clinical Trial.

Epidemiological evidence suggests that fruit and vegetable intake significantly positively affects cardiovascular health. Since vegetable juice is more accessible than raw vegetables, it attracts attention as a health functional food for circulatory diseases. Therefore, this study measured blood lipids, antioxidants, blood circulation indicators, and changes in the microbiome to confirm the effect of organic vegetable mixed juice (OVJ) on improving blood circulation. This 4-week, randomized, double-blinded, placebo-controlled study involved adult men and women with borderline total cholesterol (TC) and low-density lipoprotein (LDL) levels. As a result, blood lipid profile indicators, such as TC, triglycerides, LDL cholesterol, and apolipoprotein B, decreased (p < 0.05) in the OVJ group compared with those in the placebo group. Additionally, the antioxidant biomarker superoxide dismutase increased (p < 0.05). In contrast, systolic and diastolic blood viscosities, as blood circulation-related biomarkers, decreased (p < 0.05) in the OVJ group compared with those in the placebo group. After the intervention, a fecal microbiome analysis confirmed differences due to changes in the intestinal microbiome composition between the OVJ and placebo groups. In conclusion, our research results confirmed that consuming OVJ improves blood circulation by affecting the blood lipid profile, antioxidant enzymes, and microbiome changes.

Sociodemographic inequalities in cardiovascular risk factors among adolescents from indigenous areas in Chiapas, Mexico.

This study was aimed to determine the prevalence of cardiovascular risk factors among different sociodemographic groups of adolescents from indigenous communities in Chiapas, Mexico. A cross-sectional prevalence study was performed in urban and rural communities in the Tzotzil-Tzeltal and Selva regions of Chiapas. A sample of 253 adolescents was studied, of whom 48% were girls and 52% were boys. A descriptive analysis of quantitative variables was performed using measures of central tendency and dispersion. The prevalence of cardiovascular risk factors stratified by sex, geographical area, years of schooling, and ethnicity of the mothers was estimated. The prevalence of cardiovascular risk factors was analyzed in relation to the sociodemographic characteristics of the study population. Low HDL-c (51%) was the predominant cardiovascular risk factor. Girls had a higher prevalence of abdominal obesity, hypertriglyceridemia, and borderline total cholesterol than boys. High diastolic blood pressure was more prevalent in boys. Adolescents from urban areas had a higher prevalence of overweight/obesity and insulin resistance than adolescents from rural areas. The prevalence of overweight/obesity and abdominal obesity was higher in adolescents whose mothers had ≥ 7 years of schooling compared with adolescents with less educated mothers. Differences by maternal ethnicity also influenced the prevalence of insulin resistance. Among the main findings, this study associated sociodemographic and geographical inequalities with cardiovascular risk factors. Promoting a healthy lifestyle for this young population is absolutely necessary to prevent cardiovascular diseases in adulthood.

Markers of chronic disease risk in a cohort of Aboriginal children: findings from the Study of Environment on Aboriginal Resilience and Child Health (SEARCH)

ObjectiveThis study investigated chronic disease risk markers among a cohort of Aboriginal children in New South Wales. MethodsDistributions of body mass index (BMI), blood lipids and haemoglobin A1c (HbA1c) among Aboriginal children aged 5‐<19 years were investigated. Prevalence ratios (PR) were calculated for borderline/high total cholesterol, low‐density lipoprotein (LDL) cholesterol and HbA1c, and low high‐density lipoprotein (HDL) cholesterol, by age group, sex and BMI. ResultsAlmost half (46.8%) of the cohort, had a normal BMI and 53.3% had overweight or obesity. Prevalence of chronic disease risk markers was low, with no individuals having high total cholesterol (0.0%) and few having high LDL (3.0%) or borderline/high HbA1c (2.6%); 85.5% of the cohort had normal HDL. There was no significant variation in the prevalence of chronic disease risk markers by age group or sex. The prevalence of borderline total cholesterol was 28% higher (PR 1.28, 95%CI 1.06‐1.54), and the prevalence of low HDL was double (2.00, 1.19‐3.35) for participants with obesity versus normal BMI. ConclusionsDyslipidaemia and elevated HbA1c prevalence was low in the cohort, increasing with high BMI. Overweight and obesity were common, which increase the risk of developing chronic disease later in life. Implications for public healthFindings indicate few Aboriginal children have dyslipidaemia and hyperglycaemia, supporting screening for chronic disease risk factors from 18 years of age. Opportunities to reduce overweight and obesity among children should be considered to decrease the future risk of chronic disease.

Comorbidities associated with different levels of total cholesterol in male and female acute ischemic stroke patients.

Men and women differ in their clinical risk factors with respect to various predictors of severity in acute ischemic stroke (AIS). High cholesterol is a risk factor for AIS and the mechanism by which high cholesterol levels lead to an AIS is well established. However, the specific relationship between demographic, clinical risk factors, total cholesterol, and the resulting gender difference in AIS patients is yet to be investigated. This study recruited AIS patients between January 2000 and June 2016 classified into normal, borderline or high total cholesterol (TC). Normal was defined as ≤200 mg/dl, borderline 200 to 239 mg/dl and high ≥240 mg/dl based on Adult Treatment Panel III (ATP III) Guidelines for the classification of TC levels. The logistic regression model was used to predict clinical risk factors associated within men and women AIS patients with different levels of TC. A total of 3532 AIS patients presented with normal TC, 760 patients with borderline TC and 427 patients with high TC. The high total cholesterol group was more likely to be women with increasing age (OR = 1.028, 95% CI, 1.006–1.052, P = .014), body mass index (BMI) (OR = 1.052, 95% CI, 1.004–1.102, P = .033), and high-density lipoprotein cholesterol (HDL-C) (OR = 1.039, 95% CI, 1.019–1.060, P < .001), while those with coronary artery disease (OR = 0.435, 95% CI, 0.234–0.809, P = .003), history of drug or alcohol abuse (OR = 0.261, 95% CI, 0.079–0.867, P = .028), increasing INR (OR = 0.187, 95% CI, 0.047–0.748, P = .018), and elevated diastolic blood pressure (OR = 0.982, 95% CI, 0.970–0.995, P = .006) were associated with being a male AIS patient. There were disparities in demographic and clinical risk factors associated with high TC levels in men when compared to women and more clinical risk factors were associated with high TC levels in men when compared to women with AIS. It is important to take into account specific clinical risk factors associated with gender-related differences in total cholesterol in AIS population to facilitate personalizing their therapeutic actions.

Carotid intima-media thickness in children with Kawasaki disease

Kawasaki disease (KD) is an acute medium vessel vasculitis seen in children. The most significant long-term complication is related to coronary artery abnormalities. Use of intravenous immunoglobulins, however, has led to significant reduction in incidence of coronary aneurysms. What is more alarming is the fact that higher risk of cardiovascular disease is seen in even those children who do not have coronary artery aneurysms during subacute phase. Various factors like abnormal lipid profiles, abnormal vessel wall reactivity and endothelial dysfunction have been implicated for this. Carotid intima-media thickness (cIMT) has been used as a surrogate marker for atherosclerosis. This study was planned to evaluate cIMT in children with KD. Twenty-seven children with diagnosis of KD at least 1 year prior to enrolment were evaluated for cIMT at enrolment and then after 3 months. Fasting lipid profile was done for all patients. Mean cIMT was significantly higher in children with KD compared to controls. In lipid profiles, undesirable HDL-C and triglyceride levels were seen in 2 and 3 children, respectively. Undesirable and borderline LDL-C levels were seen in 1 and 2 patients, respectively. Undesirable and borderline total cholesterol levels were seen in 1 and 3 patients, respectively. Higher cIMTs were seen in our cohort of KD patients. Proatherogenic abnormalities in lipid profile were seen in a few patients. Both abnormalities may predict a higher risk of atherosclerosis in future. The results of this study need to be replicated on a larger study sample and over longer follow-up periods.

Nutritional Status and Lipid Profile of Young Children in Brazil

To evaluate the nutritional status and lipid profile of young children from an urban Brazilian region. Cross-sectional study involving a representative sample of 472 children aged 5-8 years from Jundiai city. The nutritional status was assessed by the body mass index for age. Total cholesterol and fractions (low-density lipoprotein cholesterol, high density lipoprotein cholesterol) and triglycerides concentrations were determined by automated enzymatic methods. The results were analyzed by the student t-test and Fisher exact test. Overweight/obesity was observed in 22% of the children and thinness in 3.2%. Girls presented a higher prevalence of overweight/obesity (24.0%) and lower levels of high-density lipoprotein cholesterol (22.8%) compared with boys (19.7% and 10.6%), respectively (p < 0.001). The prevalence of children with elevated and borderline total cholesterol was 32.8% and 26.7%, respectively, although 82.8% had desirable levels of high-density lipoprotein cholesterol. The prevalence of overweight/obesity and dyslipidaemia observed in these children is a matter of concern considering the age group evaluated.

Lipid profiles in Polish adolescents from high- and low-risk families: tracking unfavourable lipid levels over a one-year period

In a country with a high cardiovascular mortality rate, lipid profiles were studied in 929 adolescents (440 from affected and 489 from non-affected families for cardiovascular disease and hypercholesterolaemia). In 334 children with elevated or borderline total cholesterol level, lipid profiles were re-measured after a 1-y period. In boys from affected families, in contrast to boys from non-affected families, significantly higher total cholesterol levels (4.36 +/- 0.81 vs 4.19 +/- 0.78 mmol/L, p < 0.05) and LDL-C level (2.1 +/- 0.72 vs 1.89 +/- 0.79 mmol/L, p < 0.05) and significantly lower HDL-cholesterol levels (1.81 +/- 0.34 vs 1.93 +/- 0.38 mmol/L, p < 0.05) were found. The odds ratio for being in the most unfavourable decile for LDL-cholesterol was significantly higher for girls from affected families (2.17, p = 0.02). A relatively high HDL-C level as well as a favourable TC/HDL-C ratio was demonstrated in all groups, being lowest in boys from affected families. A significant correlation was found between baseline lipids and their values re-measured after 1 y. It is concluded that (1) adolescents with a positive family history are at increased risk for unfavourable lipid profile, (2) adolescents with elevated total cholesterol and LDL-cholesterol levels remain hypercholesterolaemic after a 1-y period and are therefore candidates for further biochemical and clinical monitoring, and (3) children with elevated total cholesterol may not be at high risk for cardiovascular disease owing to the favourable TC/HDL-C ratio. The study results do not indicate that general cholesterol screening in Polish adolescents is necessary, as the proportion of children with elevated LDL-cholesterol is relatively low.

Prevalence of abnormal lipid and blood pressure values among an ethnically diverse population of eighth-grade adolescents and screening implications.

Our goal was to report the prevalence of elevated blood pressure and lipid levels among eighth-grade adolescents from 3 US locations and differences by gender, ethnicity, and overweight percentile group. Fasting blood samples and blood pressure levels were obtained from 1717 eighth-grade students from 12 predominantly minority schools in 3 states (Texas, California, and North Carolina) during spring 2003. Age, gender, ethnicity, weight, and height were ascertained and BMI calculated. The presence of abnormal total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglycerides, prehypertension, hypertension, at risk for overweight, and overweight were calculated and compared with the findings of previous youth studies. We examined whether prevalence differed by gender, ethnicity, or BMI group. A total of 23.9% of participants had high blood pressure, 16.7% had borderline total cholesterol, 4.0% had high total cholesterol, 10.5% had borderline low-density lipoprotein cholesterol, 3.9% had high low-density lipoprotein cholesterol, 13.3% had low high-density lipoprotein cholesterol, and 17.2% had high triglycerides. A total of 19.8% of participants were at risk of overweight (BMI > or = 85th percentile, < 95th percentile) and 29% were overweight (BMI > or = 95th percentile). The prevalence of risk factors was associated (P < .05) with the overweight group and differed by age and gender. Prevalence of elevated blood pressure was higher in this sample than in previous national surveys in which subjects were less overweight. Associations between overweight and both elevated lipid and blood pressure levels suggest that adolescents overweight or at risk for overweight should be screened for elevated blood pressure and lipid levels.

Evaluation of risk factors for development of complications in Type II diabetes in Europe.

The Cost of Diabetes in Europe-Type II study is the first large coordinated attempt to measure the current standard of care and determine the costs of managing patients with Type II (non-insulin-dependent) diabetes mellitus. The study evaluated glycaemic control, blood lipid levels and blood pressure, all of which are risk factors for complications. Records of these clinical characteristics were collected from over 7000 patients during the 6-month study period. The mean HbAlc value for the entire study population was 7.5%, ranging from 7.0% in Sweden to 7.8% in the United Kingdom. Only 31% of individuals achieved good glycaemic control (HbAlc≤=6.5%) according to current European guidelines. Only 64% of the total study population were tested for HbAlc values at least once within the 6-month study period (ranging from 49% in Spain to 71% in the UK), although HbAlc testing every 3 months is recommended for all patients, by European Diabetes Policy Group guidelines. The majority of patients had borderline total cholesterol values, with a mean value of 5.7 mmol/1. Overall, 21% of patients were classified as having low risk cholesterol levels (<4.8 mmol/1). Good triglyceride levels (<1.7 mmol/1) were achieved by 47% of the total study population. During the study period, 81 % of patients had their blood pressure measured, with 35% and 53.3% of the patients reaching the recommended targets for systolic and diastolic blood pressure, respectively. This study showed that a high proportion of patients with risk factors for diabetes-related complications are not adequately controlled. Improvements in disease management and monitoring are therefore required to ensure that guideline targets are met, thus reducing the long-term complications of Type II diabetes.
