Association of body mass index and long-term mortality in patients from nationwide LIPIDOGRAM 2004-2015 cohort studies: no obesity paradox?

BACKGROUND: An obesity paradox has been described in relation to adverse clinical outcomes (e.g., mortality) with lower body mass index (BMI). AIMS: We sought to evaluate the association between BMI and weight loss with long-term all-cause mortality in adult populations under the care of family physicians. METHODS: LIPIDOGRAM studies were conducted in primary care in Poland in 2004, 2006, and 2015 and enrolled a total of 45,615 patients. The LIPIDOGRAM Plus study included 1627 patients recruited in the LIPIDOGRAM 2004 and repeated measurements in 2006 edition. Patients were classified by BMI categories as underweight, normal weight, overweight and class I, II, or III (obesity). Follow-up data up to December 2021 were obtained from the Central Statistical Office. Differences in all-cause mortality were analyzed using Kaplan‒Meier and Cox regression analyses. RESULTS: Of 45,615 patients, 10,987 (24.1%) were normal weight, 320 (0.7%) were underweight, 19,134 (41.9%) were overweight, and 15,174 (33.2%) lived with obesity. Follow-up was available for 44,620 patients (97.8%, median duration 15.3 years, 61.7% females). In the crude analysis, long-term all-cause mortality was lowest for the normal-weight group (14%) compared with other categories. After adjusting for comorbidities, the highest risk of death was observed for the class III obesity and underweight categories (hazard ratio, HR 1.79, 95% CI [1.55-2.05] and HR 1.57, 95% CI [1.22-2.04]), respectively. The LIPIDOGRAM Plus analysis revealed that a decrease in body weight (by 5 and 10%) over 2 years was associated with a significantly increased risk of death during long-term follow-up-HR 1.45 (95% CI 1.05-2.02, p = 0.03) and HR 1.67 (95% CI 1.02-2.74, p < 0.001). Patients who experienced weight loss were older and more burdened with comorbidities. CONCLUSIONS: Being underweight, overweight or obese is associated with a higher mortality risk in a population of patients in primary care. Patients who lost weight were older and more burdened with cardiometabolic diseases, which may suggest unintentional weight loss, and were at higher risk of death in the long-term follow-up. In nonsmoking patients without comorbidities, the lowest mortality was observed in those with a BMI < 25 kg/m2, and no U-curve relationship was observed.

Serum antinuclear autoantibodies are associated with measures of oxidative stress and lifestyle factors: analysis of LIPIDOGRAM2015 and LIPIDOGEN2015 studies.

Introduction: Oxidative stress is one of many factors suspected to promote antinuclear autoantibody (ANA) formation. Reactive oxygen species can induce changes in the antigenic structure of macromolecules, causing the immune system to treat them as "neo-antigens" and start production of autoantibodies. This study was designed to evaluate the relationship between oxidative stress markers, lifestyle factors and the detection of ANA. Material and methods: We examined measures of oxidative stress indices of free-radical damage to lipids and proteins, such as total oxidant status (TOS), concentration of protein thiol groups (PSH), and malondialdehyde (MDA), activity of superoxide dismutase (SOD) in 1731 serum samples. The parameters of the non-enzymatic antioxidant system, such as total antioxidant status (TAS) and uric acid (UA) concentration, were also measured and the oxidative stress index (OSI-index) was calculated. All samples were tested for the presence of ANA using an indirect immunofluorescence assay (IIFA). Results: The presence of ANA in women was associated with lower physical activity (p = 0.036), less frequent smoking (p = 0.007) and drinking of alcohol (p = 0.024) accompanied by significant changes in SOD isoenzymes activity (p < 0.001) and a higher uric acid (UA) concentration (p < 0.001). In ANA positive males we observed lower concentrations of PSH (p = 0.046) and increased concentrations of MDA (p = 0.047). Conclusions: The results indicate that local oxidative stress may be associated with increased probability of ANA formation in a sex-specific manner.

Metabolic syndrome is associated with similar long-term prognosis in those living with and without obesity: an analysis of 45 615 patients from the nationwide LIPIDOGRAM 2004-2015 studies.

AIMS: We aimed to evaluate the association between metabolic syndrome (MetS) and long-term all-cause mortality. METHODS AND RESULTS: The LIPIDOGRAM studies were carried out in the primary care in Poland in 2004, 2006, and 2015. MetS was diagnosed based on the National Cholesterol Education Program, Adult Treatment Panel III (NCEP/ATP III), and Joint Interim Statement (JIS) criteria. The cohort was divided into four groups: non-obese patients without MetS, obese patients without MetS, non-obese patients with MetS, and obese patients with MetS. Differences in all-cause mortality were analysed using Kaplan-Meier and Cox regression analyses. A total of 45 615 participants were enrolled (mean age 56.3, standard deviation: 11.8 years; 61.7% female). MetS was diagnosed in 14 202 (31%) by NCEP/ATP III criteria and 17 216 (37.7%) by JIS criteria. Follow-up was available for 44 620 (97.8%, median duration 15.3 years) patients. MetS was associated with increased mortality risk among the obese {hazard ratio, HR: 1.88 [95% confidence interval (CI) 1.79-1.99] and HR: 1.93 [95% CI 1.82-2.04], according to NCEP/ATP III and JIS criteria, respectively} and non-obese individuals [HR: 2.11 (95% CI 1.85-2.40) and 1.7 (95% CI 1.56-1.85) according to NCEP/ATP III and JIS criteria, respectively]. Obese patients without MetS had a higher mortality risk than non-obese patients without MetS [HR: 1.16 (95% CI 1.10-1.23) and HR: 1.22 (95% CI 1.15-1.30), respectively in subgroups with NCEP/ATP III and JIS criteria applied]. CONCLUSIONS: MetS is associated with increased all-cause mortality risk in non-obese and obese patients. In patients without MetS, obesity remains significantly associated with mortality. The concept of metabolically healthy obesity should be revised.

Metabolic syndrome (MetS) is used to describe a constellation of metabolic disturbances such as elevated blood glucose, increased levels of triglycerides and decreased level of high density lipoprotein cholesterol. They are often accompanied by elevated blood pressure and central obesity, defined as increased waist circumference. Usually, those metabolic disturbances occur in obese individuals, but sometimes, they can also occur in lean subjects. This relatively recent concept is often referred to as lean MetS. A key conclusion from our paper is that MetS, when it occurs in lean patients, is associated with similarly unfavourable long-term prognosis as in obese patients. Additionally, our analysis shows that lean patients with MetS are less often treated with lipid-lowering drugs despite having higher low density lipoprotein cholesterol levels (LDL-C). An additional finding, which is important from a public health perspective, is that obese patients who do not fulfil MetS criteria have higher long-term all-cause mortality than their lean counterparts without MetS. This finding should be an argument to encourage maintenance of normal body weight.

Design and rationale of a nationwide screening analysis from the LIPIDOGRAM2015 and LIPIDOGEN2015 studies.

Introduction: Cardiovascular disease (CVD) is a major cause of morbidity and mortality throughout the world. The LIPIDOGRAM2015 study was performed to estimate the prevalence of risk factors for atherosclerotic diseases as well as cardiovascular and related disorders in the primary care setting in Poland. The LIPIDOGEN2015 sub-study was designed to include a random cohort of patients in order to analyse parameters related to lipid metabolism, oxidative stress, inflammatory responses, autoimmune disorders, and gene variants that confer susceptibility to cardiometabolic and atherosclerotic diseases. Material and methods: The recruitment was carried out by 438 primary care physicians in Poland. The expected number of patients recruited for the LIPIDOGRAM2015 study was 13,000-14,000 with 13-15% (1700-2000) also participating in the LIPIDOGEN2015 sub-study. Each patient had to complete a questionnaire concerning medical and family history, concomitant diseases, and pharmacotherapy. Anthropometric measurements were performed at the doctor's office. For the LIPIDOGEN2015 sub-study, saliva samples for DNA isolation and blood samples for measurement of glycated haemoglobin, oxidative stress parameters, autoantibody levels, and inflammatory cytokine profile and apolipoprotein profile were collected. Follow-up data will be obtained from the National Health Fund in Poland. Results: The LIPIDOGRAM2015 and LIPIDOGEN2015 study cohort reflects the prevalence of cardiovascular risk factors and concomitant diseases, markers of oxidative stress, the presence of autoantibodies, inflammatory cytokine profile, and apolipoprotein profile, as well as genetic variants potentially conferring susceptibility to cardiometabolic and atherosclerotic diseases. Conclusions: This study presents the prevalence of different CV risk factors, with special emphasis on lipid disorders, and it assesses the relationship between inflammation, oxidative stress, and mutations in genes encoding proteins regulating lipid metabolism, as well as genes conferring susceptibility to cardiovascular, cardiometabolic, and related diseases.

Relationship Between Anti-DFS70 Autoantibodies and Oxidative Stress.

BACKGROUND: The anti-DFS70 autoantibodies are one of the most commonly and widely described agent of unknown clinical significance, frequently detected in healthy individuals. It is not known whether the DFS70 autoantibodies are protective or pathogenic. One of the factors suspected of inducing the formation of anti-DFS70 antibodies is increased oxidative stress. We evaluated the coexistence of anti-DFS70 antibodies with selected markers of oxidative stress and investigated whether these antibodies could be considered as indirect markers of oxidative stress. METHODS: The intensity of oxidative stress was measured in all samples via indices of free-radical damage to lipids and proteins such as total oxidant status (TOS), concentrations of lipid hydroperoxides (LPH), lipofuscin (LPS), and malondialdehyde (MDA). The parameters of the non-enzymatic antioxidant system, such as total antioxidant status (TAS) and uric acid concentration (UA), were also measured, as well as the activity of superoxide dismutase (SOD). Based on TOS and TAS values, the oxidative stress index (OSI) was calculated. All samples were also tested with indirect immunofluorescence assay (IFA) and 357 samples were selected for direct monospecific anti DFS70 enzyme-linked immunosorbent assay (ELISA) testing. RESULTS: The anti-DFS70 antibodies were confirmed by ELISA test in 21.29% of samples. Compared with anti-DFS70 negative samples we observed 23% lower concentration of LPH (P = .038) and 11% lower concentration of UA (P = .005). TOS was 20% lower (P = .014). The activity of SOD was up to 5% higher (P = .037). The Pearson correlation showed weak negative correlation for LPH, UA, and TOS and a weak positive correlation for SOD activity. CONCLUSION: In samples positive for the anti-DFS70 antibody a decreased level of oxidative stress was observed, especially in the case of samples with a high antibody titer. Anti-DFS70 antibodies can be considered as an indirect marker of reduced oxidative stress or a marker indicating the recent intensification of antioxidant processes.

Analysis of the impact of sex and age on the variation in the prevalence of antinuclear autoantibodies in Polish population: a nationwide observational, cross-sectional study.

The detection of antinuclear autoantibody (ANA) is dependent on many factors and varies between the populations. The aim of the study was first to assess the prevalence of ANA in the Polish adult population depending on age, sex and the cutoff threshold used for the results obtained. Second, we estimated the occurrence of individual types of ANA-staining patterns. We tested 1731 patient samples using commercially available IIFA using two cutoff thresholds of 1:100 and 1:160. We found ANA in 260 participants (15.0%), but the percentage of positive results strongly depended on the cutoff level. For a cutoff threshold 1:100, the positive population was 19.5% and for the 1:160 cutoff threshold, it was 11.7%. The most prevalent ANA-staining pattern was AC-2 Dense Fine speckled (50%), followed by AC-21 Reticular/AMA (14.38%) ANA more common in women (72%); 64% of ANA-positive patients were over 50 years of age. ANA prevalence in the Polish population is at a level observed in other highly developed countries and is more prevalent in women and elderly individuals. To reduce the number of positive results released, we suggest that Polish laboratories should set 1:160 as the cutoff threshold.

The Differences in the Prevalence of Cardiovascular Disease, Its Risk Factors, and Achievement of Therapeutic Goals among Urban and Rural Primary Care Patients in Poland: Results from the LIPIDOGRAM 2015 Study.

A nationwide cross-sectional study, LIPIDOGRAM2015, was carried out in Poland in the years 2015 and 2016. A total of 438 primary care physicians enrolled 13,724 adult patients that sought medical care in primary health care practices. The prevalence of hypertension, diabetes mellitus, dyslipidaemia, and CVD were similar in urban and rural areas (49.5 vs. 49.4%; 13.7 vs. 13.1%; 84.2 vs. 85.2%; 14.4 vs. 14.2%, respectively). The prevalence of obesity (32.3 vs. 37.5%, p < 0.01) and excessive waist circumference (77.5 vs. 80.7%, p < 0.01), as well as abdominal obesity (43.2 vs. 46.4%, p < 0.01), were higher in rural areas in both genders. Mean levels of LDL-C (128 vs. 130 mg/dL, p = 0.04) and non-HDL-C (147 vs. 148 mg/dL, p = 0.03) were slightly higher in rural populations. Altogether, 14.3% of patients with CVD from urban areas and 11.3% from rural areas reached LDL <70 mg/dL (p = 0.04). There were no important differences in the prevalence of hypertension, diabetes, dyslipidaemia, and CVD, or in mean levels of blood pressure, cholesterol fractions, glucose, and HbA1c between Polish urban and rural primary care patient populations. A high proportion of patients in cities and an even-higher proportion in rural areas did not reach the recommended targets for blood pressure, LDL-C, and HbA1c, indicating the need for novel CVD-prevention programs.

Secondary Stroke Prevention in Polish Adults: Results from the LIPIDOGRAM2015 Study.

BACKGROUND: The purpose of the study was to evaluate secondary stroke prevention in Poland and its association with sociodemographic factors, place of residence, and concomitant cardiovascular risk factors. MATERIAL AND METHODS: From all patients in LIPIDOGRAM2015 Study (n = 13,724), 268 subjects had a history of ischaemic stroke and were included. RESULTS: 165 subjects (61.6%) used at least one preventive medication. Oral antiplatelet and anticoagulation agents were used by 116 (43.3%) and 70 (26.1%) patients, respectively. Only 157 (58.6%) participants used lipid-lowering drugs, and 205 (76.5%) were treated with antihypertensive drugs. Coronary heart disease (CHD) and dyslipidaemia were associated with antiplatelet treatment (p = 0.047 and p = 0.012, respectively). A history of atrial fibrillation, CHD, and previous myocardial infarction correlated with anticoagulant treatment (p = 0.001, p = 0.011, and p < 0.0001, respectively). Age, gender, time from stroke onset, place of residence, and level of education were not associated with antiplatelet or anticoagulant treatment. Only 31.7% of patients were engaged in regular physical activity, 62% used appropriate diet, and 13.6% were current smokers. CONCLUSIONS: In Poland drugs and lifestyle modification for secondary stroke prevention are not commonly adhered to. Educational programmes for physicians and patients should be developed to improve application of effective secondary prevention of stroke.

May Measurement Month 2019: an analysis of blood pressure screening results from Poland.

May Measurement Month 2019 is the third edition of a global initiative organized by the International Society of Hypertension aimed at raising awareness of hypertension and the need for blood pressure (BP) screening. We present data analysis from Poland. To evaluate the potential of opportunistic BP measurements as a tool for cardiovascular disease prevention programmes. To collect new country data for further annual comparisons. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in 201 sites in May 2019. BP was measured in 7072 subjects (mean age: 54 ± 15 years; 62.3% females). After multiple imputation, the age- and sex-standardized systolic BP (SBP) and diastolic BP (DBP) was 125.4/78.5 mmHg in the whole group, 133.3/82.8 mmHg in individuals on antihypertensive medication and 123.3/77.7 mmHg in those not taking antihypertensive drugs. The proportion of subjects with high BP (≥140/90 mmHg) were 41.8% in subjects taking antihypertensive drugs, and 19.6% in those not taking any antihypertensive drugs. Overall, hypertension was present in 55.4% of participants (3917 out of 7072), of whom 83.0% were aware of their diagnosis. 80.4% of hypertensives were taking antihypertensive medication. 46.7% of all hypertensives had BP controlled to target (<140/90 mmHg). Higher BP correlated with body mass index and age but not tobacco smoking. SBP but not DBP was higher in diabetic participants. These data provide evidence on the current epidemiology of hypertension and may serve as a source of information to introduce primary and secondary prevention programmes to reduce cardiovascular risk in Poland.

Lipid levels, atrial fibrillation and the impact of age: Results from the LIPIDOGRAM2015 study.

BACKGROUND AND AIMS: An inverse relationship between lipid levels and atrial fibrillation (AF) has been suggested, but whether the association is upheld for all age groups remains unclear. The aim of the study was to examine associations between lipid levels and AF by age groups in a nationwide study in Poland. METHODS: Multivariate Poisson regression models were used to estimate prevalence ratios (PRs) for AF by lipid levels. Low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), total cholesterol (TC), non-HDL-C and LDL-C/HDL-C ratios were grouped into quartiles. RESULTS: Of the 13,724 participants, 5.2% (n = 708) had AF. People with AF were older with more comorbidities, but lower lipid levels (all p < 0.05). The prevalence of AF was inversely associated with LDL-C (Adjusted PR (95% Confidence Interval) highest versus lowest quartile: 0.60 (0.48, 0.75)), TC (0.61 (0.49, 0.75)) and non-HDL-C (0.63 (0.51, 0.78)). The prevalence of AF was inversely associated with HDL-C (0.58 (0.46, 0.74)), but this was not statistically significant for people aged 75 years and older. For the LDL-C/HDL-C ratio, the prevalence of AF was only inversely associated with higher levels for people aged 75 years and older (0.75 (0.61, 0.94)). There was no statistically significant difference in prevalence of AF by TG levels. CONCLUSIONS: The results suggest an inverse relationship between lipid levels and AF. The inverse association between higher HDL-C and AF was only significant for people aged <75 years, whereas the inverse association between higher LDL-C/HDL-C ratio and AF was only significant for people aged 75 years and older.

May Measurement Month 2018: an analysis of blood pressure screening campaign results from Poland.

Hypertension remains the most important cardiovascular risk factor in Poland. May Measurement Month is a global initiative organized by the International Society of Hypertension aimed at raising awareness of hypertension and the need for blood pressure (BP) screening and demonstrating the potential of the opportunistic BP measurements. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in 146 sites in May 2018. Blood pressure was measured in 6450 subjects (mean age: 41 ± 15 years; 59% females). After multiple imputation, the age and sex standardized systolic and diastolic BP was 126.7/78.4 mmHg in the whole analysed group, 132.8/81.3 mmHg in subjects taking antihypertensive drugs, and 125.7/78.0 mmHg in those not taking any antihypertensive drugs. After multiple imputation, the proportions of subjects with high BP (systolic ≥140 mmHg or diastolic ≥90 mmHg or on treatment for raised BP) were 22.2% in the whole analysed group, 39.2% in subjects taking antihypertensive drugs, and 18.6% those not taking any antihypertensive drugs. Overall, hypertension was present in 32.8% of participants, among them 38.7% were not aware of the disease, 53.1% were taking antihypertensive drugs, and 32.3% had BP controlled to target (<140/90 mmHg). Blood pressure was increasing with increasing body mass index and alcohol intake. Smokers and project participants with diabetes had increased average BP. In conclusion, this project provides additional evidence for a considerable potential for further reduction of cardiovascular risk through improvement in detection and treatment of hypertension in Poland.

The prevalence of cardiovascular risk factors and cardiovascular disease among primary care patients in Poland: results from the LIPIDOGRAM2015 study.

BACKGROUND AND AIM: To estimate the prevalence of cardiovascular (CV) disease and CV risk factors among Polish patients. METHODS: A nationwide cross-sectional study, LIPIDOGRAM2015, was carried out in Poland in the 4th quarter of 2015 and 1st and 2nd quarters of 2016; 438 primary care physicians enrolled 13,724 adult patients that sought medical care in primary health care practices. RESULTS: Nearly 19% of men and approximately 12% of women had cardiovascular disease (CVD). Over 60% of the recruited patients had hypertension (HTN), >80% had dyslipidaemia and <15% of patients were diagnosed with diabetes (DM). All of these disorders were more frequent in men. In 80% of patients the waist circumference exceed norm for the European population. Less than half of the patients were current smokers or had smoked in the past. Patients with CVD had significantly higher blood pressure and glucose levels but lower low density lipoprotein-cholesterol level. CONCLUSIONS: The prevalence of CVD and CV risk factors among patients in Poland is high. CVD is more common in men than in women. The most common CV risk factors are excess waist circumference, dyslipidaemia and HTN. Family physicians should conduct activities to prevent, diagnose early and treat CVD in the primary health care population.

Do we know more about hypertension in Poland after the May Measurement Month 2017?-Europe.

Elevated blood pressure (BP) is a worldwide burden, leading to over 10 million deaths yearly. May Measurement Month (MMM) is a global initiative organized by the International Society of Hypertension aimed at raising awareness of hypertension and the need for BP screening. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2017. BP measurement, the definition of hypertension and statistical analysis followed the globally approved MMM17 Study Protocol. In Poland 5834 (98.9%, Caucasian) individuals were screened. After multiple imputation, 2601 (35.3%) had hypertension. Of individuals not receiving anti-hypertensive medication, 976 (20.6%) were hypertensive. Of individuals receiving anti-hypertensive medication, 532 (49.1%) had uncontrolled BP. In the crude screened group, 81.4% declared to not receive any anti-hypertensive treatment, while the remaining 18.6% were on such medications. In overweight and obese patients both systolic and diastolic BP were significantly higher than in normal weight and underweight subjects. In addition, BP measured on Sundays was significantly lower than on Mondays. MMM17 was one of the largest recent BP screening campaigns in Poland. We found that over 1/3 of participants were hypertensive. Almost half of the treated subjects had uncontrolled BP. These results suggest that opportunistic screening can identify substantial numbers with raised BP.

The relation of rapid changes in obesity measures to lipid profile - insights from a nationwide metabolic health survey in 444 Polish cities.

OBJECTIVE: The impact of fast changes in obesity indices on other measures of metabolic health is poorly defined in the general population. Using the Polish accession to the European Union as a model of political and social transformation we examined how an expected rapid increase in body mass index (BMI) and waist circumference relates to changes in lipid profile, both at the population and personal level. METHODS: Through primary care centres in 444 Polish cities, two cross-sectional nationwide population-based surveys (LIPIDOGRAM 2004 and LIPIDOGRAM 2006) examined 15,404 and 15,453 adult individuals in 2004 and 2006, respectively. A separate prospective sample of 1,840 individuals recruited in 2004 had a follow-up in 2006 (LIPIDOGRAM PLUS). RESULTS: Two years after Polish accession to European Union, mean population BMI and waist circumference increased by 0.6% and 0.9%, respectively. This tracked with a 7.6% drop in HDL-cholesterol and a 2.1% increase in triglycerides (all p<0.001) nationwide. The direction and magnitude of the population changes were replicated at the personal level in LIPIDOGRAM PLUS (0.7%, 0.3%, 8.6% and 1.8%, respectively). However, increases in BMI and waist circumference were both only weakly associated with HDL-cholesterol and triglycerides changes prospectively. The relation of BMI to the magnitude of change in both lipid fractions was comparable to that of waist circumference. CONCLUSIONS: Moderate changes in obesity measures tracked with a significant deterioration in measures of pro-atherogenic dyslipidaemia at both personal and population level. These associations were predominantly driven by factors not measureable directly through either BMI or waist circumference.

The prevalence rate of overweight and obesity among adult patient population in Poland, according to the LIPIDOGRAM2004 and LIPIDOGRAM2006 studies, in context of previous Polish national screening surveys.

An increase of the body mass often aggravates cardiovascular risk factors. In Poland, over the past 25 years, some epidemiological studies, focused on body mass disorders were conducted. Their results suggest an increase of the prevalence rate of overweight and obesity. The goal of the studies LIPIDOGRAM2004 and LIPIDOGRAM2006 was to assess the prevalence rate of abnormal body mass among adult patients remaining under the care of family physicians in Poland. 17.065 patients in 2004 and 17.152 in 2006, older than 30 years, recruited by 675 study physicians in 444 sites across Poland, were involved into these studies. It was found that approximately 3/4 of the patients included into these studies had BMI > or = 25 kg/m2. Overweight rate was much more prevalent among men than women (48,0% vs. 39,2% in 2004, p<0,0001; 47,4% vs. 39,7% in 2006, p<0,0001). In 2004, obesity was present in above 30% of the participants, including small, but statistically significant difference in the population of men (32,8% vs. 31,2%, p<0,05). In 2006, an increase in the prevalence of obesity in men, compared to women was reported (34,7% vs. 31,6%, p<0,001). Health care actions aimed at decreasing these phenomena would require targeted efforts of family physicians, in collaboration with a multidisciplinary team of specialists.

Prevention of coronary heart disease in primary medical care in Poland: results from the LIPIDOGRAM study.

AIMS: To determine: (1) achievement of cholesterol therapy goals in patients receiving lipid-lowering drugs in Polish primary care between the years 2004 and 2006; (2) the characteristics of patients that are associated with attainment of these goals. DESIGN: Cross-sectional study in randomly selected Polish primary care practices. METHOD: 5248 patients aged over 30 years in 2004 and 5386 patients in 2006, who were taking cholesterol-lowering treatment took part in the study. Physicians recorded demographic and medical history data using a standardized questionnaire, including weight and height, and collected blood samples of patients to determine their cholesterol level. RESULTS: 18.5% of patients attained their optimal goals of therapy (total cholesterol, TC; low-density lipoprotein cholesterol, LDL-C) in 2004 compared to 25.2% in 2006 (p < 0.001). In both 2004 and 2006, more patients achieved their target levels for LDL-C than for TC and statins were the most commonly used medication (85% and 91%, respectively). Male sex, smoking, and higher education were the strongest correlates of the therapeutic outcome. The odds ratio of achieving cholesterol therapy goals in men, non-smokers, and university graduates was estimated at 1.51, 0.70, 1.38 in 2004 and 1.50, 0.73, 1.34 in 2006, respectively. CONCLUSION: There was a measurable improvement in the effectiveness of hypercholesterolaemia treatment between 2004 and 2006 but the majority of patients remain inadequately treated, with goals not being achieved. There is a need to raise the standard of lipid-lowering management in Poland.

Prevalence of dyslipidemia and general ineffectiveness of its treatment in both primary and secondary prevention of coronary heart disease within family medicine framework--results of LIPIDOGRAM 2005--a nationwide epidemiological study. Dyslipidemia in Poland--ineffective treatment.

PURPOSE: Despite major advances in cardiology dyslipidemia continues to be underdiagnosed and undertreated. The study aimed to evaluate current prevalence of dyslipidemia and treatment efficacy in both coronary and non-coronary subjects. METHODS: 17,065 subjects aged 30-95 years (20.51%--coronary heart disease (CHD) patients), seeking medical help for disparate reasons from 675 family physicians, were randomly enrolled. Family physicians completed pertinent questionnaires against available medical records and measured patients' lipid levels during a single appointment. RESULTS: Dyslipidemia was detected in 73% of the CHD subjects vs. 46% of the non-CHD ones (p = 0.00001); its severity differing regionally. Hypolipemic treatment was administered to 82% of the CHD subjects vs. 12% of the non-CHD ones (p = 0.00001). Mean concentrations of LDL-cholesterol were higher in the treated subjects (p = 0.00002). Only 10% of the CHD subjects and 20% of the non-CHD ones were treated effectively for dyslipidemiae. CONCLUSIONS: Dyslipidemia was found widely prevalent nationwide, as well as poorly pharmacologically controlled in both primary and secondary prevention. Diversity of economic factors notwithstanding, this was mainly attributable to ineffective patient educational policies, meriting therefore immediate expansion and enhancement of existing disease management system in terms of adequate monitoring and effective treatment of key coronary risk factors.
