Twenty-year trends in serum cholesterol, hypercholesterolemia, and cholesterol medication use - The Minnesota Heart Survey, 1980-1982 to 2000-2002
ABSTRACT Although US cholesterol concentrations have dropped, &50% of adults have total cholesterol concentrations > or =5.18 mmol/L, putting them at "borderline-high risk" for heart disease. Whether the decline has continued into the 21st century is unknown. We assessed 20-year trends in cholesterol, hypercholesterolemia, lipid-lowering drug use, and cholesterol awareness, treatment, and control from Minnesota Heart Survey (MHS) data.
Five independent, cross-sectional, population-based surveys of 2500 to 5000 adults were conducted in the Minneapolis-St. Paul, Minn, area from 1980 to 2002. Mean (nonfasting) total cholesterol concentrations have continued a 20-year decline, punctuated by an intervening lull. Age-adjusted mean total cholesterol concentrations in 2000 to 2002 were 5.16 and 5.09 mmol/L for men and women, respectively (in 1980 to 1982, 5.49 and 5.38 mmol/L for men and women, respectively) However, the decline has not been uniform across all age groups. Middle-aged to older people have shown substantial decreases, but younger people have shown little overall change and recently had increased total cholesterol values. The mean prevalence of hypercholesterolemia in 2000 to 2002 was 54.9% for men and 46.5% for women and has decreased significantly for both during the study. Age-adjusted mean high-density lipoprotein cholesterol concentrations in 2000 to 2002 were 1.09 and 1.40 mmol/L for men and women, respectively, and were not different from the prior survey. Lipid-lowering drug use rose significantly for both sexes aged 35 to 74 years. Awareness, treatment, and control of hypercholesterolemia have increased; however, more than half of those at borderline-high risk remain unaware of their condition.
Although hypercholesterolemia prevalence continued to fall, significant population segments still have cholesterol concentrations near or at the level of increased risk.

ABSTRACT: Introduction The aim of this study was to evaluate changes in the levels of certain lipids in a group of participants in the Prophylaxis and Early Detection of Cardiovascular Diseases Programme and also to determine factors contributing to positive changes in the variables. Materials and methods The study was conducted in Zgierz, a town in central Poland. 458 people, former participants of the Prophylaxis and Early Detection of Cardiovascular Diseases Programme, were included in the study. The study tool was a questionnaire. The authors made laboratory tests to determine the lipid profile and serum glucose. They also took arterial pressure twice and made anthropometric measurements. The authors used single-factor logistic regression to evaluate the obtained results. They adopted statistical significance level of p<0.05. The data were presented as odds ratios (OR) with 95% confidence intervals (CIs). Results A positive change in TC levels was observed in 64% of the respondents, LDL cholesterol level in 47.8% and HDL cholesterol level in 60.7%. In 46.5% of the respondents, a decrease in the level of triglycerides was observed. Conclusions There is a need to initiate prophylactic activities, especially among males, people who are less educated and also among older people.Central European Journal of Medicine 10/2014; 9(5).

ABSTRACT: The etiology of an ischemic stroke remains undetermined in 20-35% of cases and many patients do not have any of the conventional risk factors. Increased visceral adipose tissue (VAT) is a suggested new risk factor for both carotid artery atherosclerosis (CAA) and atrial fibrillation (AF), but its role in the remaining stroke population is unknown. We assessed the amount of VAT in patients with embolic stroke of undetermined source (ESUS) after excluding major-risk cardioembolic sources, occlusive atherosclerosis, and lacunar stroke. Altogether 58 patients (mean age 57.7±10.2 years, 44 men) with ischemic stroke of unknown etiology but without CAA, known AF or small vessel disease underwent computed tomography angiography and assessment of VAT. For comparison VAT values from three different reference populations were used. Conventional risk factors (smoking, hypertension, diabetes, increased total and LDL-cholesterol, decreased HDL-cholesterol) were also registered. Mean VAT area was significantly higher in stroke patients (205±103 cm2 for men and 168±99 cm2 for women) compared to all reference populations (P<0.01). 50% of male and 57% of female patients had an increased VAT area. In male patients, VAT was significantly higher despite similar body mass index (BMI). Increased VAT was more common than any of the conventional risk factors. Increased VAT was found in over half of our patients with ESUS suggesting it may have a role in the pathogenesis of thromboembolism in this selected group of patients.PLoS ONE 03/2015; 10(3):e0120598.

ABSTRACT: Background The prevalence and determinants of dyslipidemia patterns among Hispanics/Latinos are not well known. Methods Lipid and lipoprotein data were used from the Hispanic Community Health Study / Study of Latinos -- a population-based cohort of 16,415 US Hispanic/Latinos ages 18-74. National Cholesterol Education Program cutoffs were employed. Differences in demographics, lifestyle factors, biological and acculturation characteristics were compared among those with and without dyslipidemia. Results Mean age was 41.1 years and 47.9% were male. The overall prevalence of any dyslipidemia was 65.0%. The prevalence of elevated LDL-C was 36.0% and highest among Cubans (44.5%; p<0.001). Low HDL-C was present in 41.4% and did not significantly differ across Hispanic background groups (p=0.09). High triglycerides were seen in 14.8% of Hispanics/Latinos, most commonly among Central Americans (18.3%; p<0.001). Elevated non-HDL-C was seen in 34.7% with the highest prevalence among Cubans (43.3%; p<0.001). Dominicans consistently had a lower prevalence of most types of dyslipidemia. In multivariate analyses, the presence of any dyslipidemia was associated with increasing age, body mass index and low physical activity. Older age, female gender, diabetes, low physical activity, and alcohol use were associated with specific dyslipidemia types. Spanish-language preference and lower educational status were associated with higher dyslipidemia prevalence. Conclusion Dyslipidemia is highly prevalent among US Hispanics/Latinos; Cubans seem particularly at risk. Determinants of dyslipidemia varied across Hispanic backgrounds with socioeconomic status and acculturation having a significant effect on dyslipidemia prevalence. This information can help guide public health measures to prevent disparities among the US Hispanic/Latino population.The American Journal of Medicine 12/2014; 127(12).
