Abstract
Background Statin therapy is a cornerstone of cardiovascular disease risk reduction for people with diabetes mellitus. Past reports have shown race‐sex differences in statin use in general populations, but statin patterns by race and sex in those with diabetes mellitus have not been thoroughly studied. Methods and Results Our sample of 4288 adults ≥45 years of age with diagnosed diabetes mellitus who had low‐density lipoprotein cholesterol (LDL‐C) >100 mg/dL or were taking statins recruited for the Reasons for Geographic and Racial Differences in Stroke study from 2003 to 2007. Exposures included race‐sex groups (white men [WM], black men [BM], white women [WW], black women [BW]) and factors that may influence healthcare utilization. Proportions and prevalence ratios were calculated for statin use and LDL‐C control. Statin use for WM, BM, WW, and BW was 66.0%, 57.8%, 55.0%, and 53.6%, respectively (P<0.001). After adjustment for healthcare utilization factors, statin use was lower for BM, WW, and BW compared with WM (prevalence ratios [95%CI]: 0.96 [0.89‐1.03], 0.86 [0.80‐0.92], and 0.87 [0.81‐0.93], respectively, P<0.001). LDL‐C control among those taking statins for WM, BM, WW, and BW was 75.3%, 62.7%, 69.0%, and 56.0%, respectively (P<0.001). After adjustment, LDL‐C control was lower for BM, WW, and BW compared with WM (prevalence ratios [95%CI]: 0.85 [0.79‐0.93], 0.89 [0.82‐0.96], and 0.73 [0.67‐0.80], respectively, P<0.001). Conclusions Race‐sex disparities in statin use and LDL‐C control were only partly explained by factors influencing health services utilization. Healthcare provider awareness of these disparities may help to close the observed race‐sex gaps in statin use and LDL‐C control among people with diabetes mellitus.

Abstract
BACKGROUND Non-compaction cardiomyopathy (NCCM) is a cardiomyopathy characterized by left ventricular tribeculae and deep intertrabecular recesses. Because of its genetic underpinnings and physical disease burden, noncompaction cardiomyopathy is expected to be associated with a lower health status and increase in pscyhological distress. PURPOSE This study determined the health status and psychological distress in NCCM patients. We also examined the potential contribution of genetic predisposition and cardiac symptoms to health status and distress in NCCM, by comparing NCCM patients with (1) patients with familial hypercholesterolemia (FH) and (2) patients with acquired dilated cardiomyopathy (DCM). METHODS Patients were recruited from the Erasmus Medical Center, Rotterdam, The Netherlands. Using a case-control design, NCCM patients (N = 45, mean age 46.7 ± 15.1 years, 38 % male) were compared with 43 FH patients and 42 DCM patients. Outcome measures were health status (Short Form Health Survey-12), anxiety (Generalized Anxiety Disorder 7-item scale) and depression (Patient Health Questionnaire 9-item scale). RESULTS NCCM patients showed significantly worse health status (Physical Component Score F(1,84) = 9.58, P = .003; Mental Component Score F(1,84) = 16.65, P < .001), anxiety (F(1,85) = 9.63, P = .003) and depression scores (F(1,82) = 5.4, P = .023) compared to FH patients, also after adjusting age, sex, comorbidity, educational level and time since diagnosis. However, NCCM patients did not differ from DCM patients (Physical Component Score F(1,82) = 2,61, P = .11; Mental Component Score F(1,82) = .55, P = .46), anxiety (F(1,82) = 1.16, P = .28) and depression scores (F(1,82) = 1,95, P = .17). CONCLUSION Cardiac symptoms are likely to play a role in the observed poor health status and elevated levels of anxiety and depressive symptoms in NCCM, whereas the burden of having a genetic condition may contribute less to these health status and psychological measures.

Abstract
BACKGROUND The purposes of this cohort study were to establish how frequently people with physician-diagnosed diabetes self-reported the disease, to determine factors associated with self-reporting of diabetes, and to evaluate subsequent differences in self-management behaviour, health care utilisation and clinical outcomes between people who do and do not report their disease. METHODS We used a registry of physician-diagnosed diabetes as a reference standard. We studied respondents to a 2000/01 population-based health survey who were in the registry (n = 1,812), and we determined the proportion who reported having diabetes during the survey. Baseline factors associated with self-report and subsequent behavioural, utilisation and clinical differences between those who did and did not self-report were defined from the survey responses and from linkage with administrative data sources. RESULTS Only 75% of people with physician-diagnosed diabetes reported having the disease. People who did self-report were more likely to be male, to live in rural areas, to have longer disease duration and to have received specialist physician care. People who did not report having diabetes in the survey were markedly less likely to perform capillary blood glucose monitoring in the subsequent two years (OR 0.05, 95% CI 0.02 to 0.08). They were also less likely to receive specialist physician care (OR 0.55, 95% CI 0.37 to 0.86), and were less likely to require hospital care for hypo- or hyperglycaemia (OR 0.09, 95% CI 0.01 to 0.28). CONCLUSION Many people with physician-diagnosed diabetes do not report having the disease, but most demographic and clinical features do not distinguish these individuals. These individuals are much less likely to perform capillary glucose monitoring, suggesting that their diabetes self-management is inadequate. Clinicians may be able to use the absence of glucose monitoring as a screening tool to identify people needing a detailed evaluation of their disease knowledge.

Abstract
AIM The 'labelling hypothesis' was introduced on the basis of the observation that labelling subjects with blood pressure elevation as hypertensive was associated with an increase in sickness absence. In the Belstress I study this hypothesis was analysed in the same way for the possible influence on sick leave of labelling persons with elevated cholesterol as hypercholesterolaemic. METHODS AND RESULTS The Belstress I cohort concerns a sample of more than 16,000 men and 5,000 women at work in 24 Belgian industries in various sectors. Baseline data were collected by questionnaire and clinical examination. Awareness was defined as answering positively to the question 'did a physician ever tell you that your blood pressure/serum cholesterol was too high?' Sick leave data were independently and objectively recorded during 1 year following the screening. Sick leave was treated in a dichotomous way whereby the event was defined as being in the highest quartile of the annual number of days of sick leave (10 days or more for men and 15 days or more for women) or as being in the highest quartile of the annual number of spells of sick leave (two spells or more for both sexes). Gender-specific logistic regression analyses were performed, with adjustment for a large set of covariates. A positive association was observed between both awareness of hypertension and awareness of hypercholesterolaemia and the various definitions of sick leave, in both sexes and after adjustment for different covariates. When dividing up aware subjects into treated versus untreated, we observed in men the highest sick leave incidence in aware and treated hypertensive patients as well as in aware and treated hypercholesterolaemic patients. In women findings were less consistent, probably due to the smaller sample size. When looking at cumulative effects by examining participants with both hypertension and hypercholesterolaemia and their level of awareness for one or both risk factors, a statistically significant gradient was noticed in men, with the highest sick leave incidence, whatever the definition, in men aware for both risk factors, followed by men aware for one. In women the same trends were observed, but no level of statistical significance was reached. CONCLUSION Without being able to test the effect of 'labelling' as such, our study provides support for the association between awareness of two different coronary risk factors and incidence of sick leave. Probably a common mechanism is at the base of these findings. Further research is needed, in order to reduce potential negative effects of screening on human wellbeing as well as on productivity.

Abstract
The authors conducted a community-based cholesterol screening study to examine accuracy of recall for self-relevant health information in long-term autobiographical memory. Adult community residents (N = 496) were recruited to participate in a laboratory-based cholesterol screening and were also provided cholesterol counseling in accordance with national guidelines. Participants were subsequently interviewed 1, 3, or 6 months later to assess their memory for their test results. Participants recalled their exact cholesterol levels inaccurately (38.0% correct) but their cardiovascular risk category comparatively well (88.7% correct). Recall errors showed a systematic bias: Individuals who received the most undesirable test results were most likely to remember their cholesterol scores and cardiovascular risk categories as lower (i.e., healthier) than those actually received. Recall bias was unrelated to age, education, knowledge, self-rated health status, and self-reported efforts to reduce cholesterol. The findings provide evidence that recall of self-relevant health information is susceptible to self-enhancement bias.

Abstract
OBJECTIVE To explore how persons with an elevated cardiovascular risk score (CRS) balanced health-related advice against the life they wanted to live or were able to live. SETTING 2000 Danes aged 30-50 were invited to participate in a health-screening project in general practice. Screenings were conducted at baseline and after one and five years, and included among other screening procedures a calculation of CRS (see Figure 1). DESIGN Participants with an elevated CRS were asked to participate in a qualitative semi-structured interview. They were selected by stratified purposeful sampling reflecting variations in age, sex. and perceived health. SUBJECTS Nine men and five women aged 33-50 years. THEORETICAL FRAMES OF REFERENCE: Bandura's theory of self-efficacy and the Health Belief Model's consideration of individuals' cues to act against a health threat supported analysis. RESULTS Being informed about an elevated CRS had a considerable impact on the informants. They initiated significant lifestyle changes, though only to a limited degree when such changes would affect their quality of life adversely. In cases where other results of the multiphasic screening were normal, interpreted as such, or if there were stressful circumstances in the informant's life, the elevated CRS receded into the background. INTERPRETATION Doctors, who inform individuals about the impact of risk factors, need to know that the consequences and health advice are not always interpreted by laypeople as supposed by the medical culture.

Abstract
BACKGROUND The primary aim of this study was to compare quality-of-life outcome between patients randomized to implantable cardioverter defibrillator (ICD) therapy and patients randomized to amiodarone treatment in the Canadian Implantable Defibrillator Study (CIDS). A secondary aim was to evaluate the effects on quality-of-life outcomes of receiving shocks from the device. METHODS Quality of life was assessed in 317 English-speaking participants by use of the Rand Corporation's 38-item Mental Health Inventory (MHI) and the Nottingham Health Profile (NHP). Assessments were done in the hospital at baseline and with mailed questionnaires after 2, 6, and 12 months of follow-up. Sixty-two percent of patients completed the follow-up assessments at 6 and 12 months. RESULTS Repeated measures analysis of variance revealed significant time by treatment group interaction effect on total MHI and the psychological distress and psychological well-being sub-scales, and on 5 of the 7 NHP scales (energy, physical mobility, emotional reactions, sleep disturbance, and lifestyle impairment) (P <.05). Emotional and physical health scores were shown to improve significantly in the ICD group and were either unchanged (emotional health) or deteriorated (energy and physical mobility) in the amiodarone-treated group by means of post-hoc comparisons. Quality of life did not improve in the subgroup of patients in the ICD-treated group who received > or =5 shocks from their device. CONCLUSION Quality of life is better with ICD therapy than with amiodarone therapy. The beneficial quality-of-life effects from an ICD are not evident in patients who receive numerous shocks from their device.

Abstract
OBJECTIVES The primary aim of this study was to analyse quality of life in adult patients with familial hypercholesterolaemia (FH), a genetic disorder with increased risk of coronary heart disease (CHD). Secondary aims were to find explanatory factors for quality of life and anxiety. DESIGN A descriptive cross-sectional design was used. SETTING Outpatients from lipid clinics at two university hospitals in Sweden were included. Patients with heterozygous FH and a randomly selected control group participated by filling out questionnaires. SUBJECTS Two hundred and eighty patients with heterozygous FH above 18 years of age were asked, and 212 of whom 185 were free of overt CHD, participated. Of a control group of 2980 persons 1485 were included for comparison. METHODS We used Likert-type questionnaires: the Quality of Life Index (QLI) consisting of four subscales, the Hospital Anxiety and Depression Scale (HAD), the Mastery Scale measuring coping and a questionnaire on health and lipids constructed for FH patients. RESULTS Patients with FH were significantly more satisfied with overall quality of life 21.8 +/- 0.3 (SEM) vs. controls 21.1 +/- 0.1 and this was also the case in three of four subscales, all differences P < 0.05. Anxiety about getting CHD was expressed amongst 86% of the patients with FH. CONCLUSIONS Quality of life amongst patients with FH was at least as good as in controls but they were worried about getting CHD.

Abstract
OBJECTIVE To assess use of cholesterol-lowering therapy and related beliefs among middle-aged adults after myocardial infarction. DESIGN Telephone survey and administrative data. SETTING National managed-care company. PARTICIPANTS Six hundred ninety-six adults age 30 to 64 surveyed in 1999, approximately 1 to 2 years after a myocardial infarction. MEASUREMENTS Use of cholesterol-lowering drugs, beliefs about the importance of lowering cholesterol, and knowledge of personal cholesterol level, adjusting for demographic and clinical factors with logistic regression. MAIN RESULTS Among respondents, 62.5% reported they were taking a cholesterol-lowering drug. In adjusted analyses, these drugs were used significantly less often by African-American patients and those with congestive heart failure or peripheral vascular disease, and more often by college graduates, patients with hypertension, and those who had seen a cardiologist since their myocardial infarction. Lowering cholesterol was viewed as "very important"; by 87.1% of patients, but significantly less often by smokers and more often by those who had undergone coronary angioplasty or bypass surgery. Only 42.5% of respondents knew their cholesterol level, and this knowledge was significantly less common among less-educated or less-affluent patients, African-American patients, and patients who smoked or had diabetes or peripheral vascular disease. CONCLUSIONS Although most patients recognized the importance of lowering cholesterol after myocardial infarction, several clinical and demographic subgroups were less likely to receive cholesterol-lowering therapy, and many patients were unaware of their cholesterol level. Health-care providers and managed-care plans can use these findings to promote cholesterol testing and treatment for patients with coronary heart disease who are most likely to benefit from these efforts.

Abstract
BACKGROUND Total cholesterol (TC) and lipoprotein measurements are among the major risk factors for cardiovascular disease (CVD). ISSUES The massive (and increasing) disease burden associated with cardiovascular disorders justifies public health measures, such as screening, which may assist with the identification and treatment of individuals who have a high risk of developing these disorders. Whole populations are placed at risk by environmental factors such as dietary habits and exercise patterns, and this may be reflected by simple tests such as TC that largely depend on dietary consumption of saturated fat and cholesterol. On the other hand, identification of high-risk individuals within populations requires more specific tests such as measurement of cholesterol in lipoprotein fractions. This recognizes that the contribution of different risk factors may vary between individuals. Dietary and pharmacological interventions, particularly those that reduce low-density lipoprotein cholesterol (LDL-C), have been shown to prevent the onset or recurrence of CVD. CONCLUSIONS It is desirable and justifiable to try to identify high-risk patients before the onset of clinical CVD because morbidity and mortality may occur as a consequence of the initial event. The relationship between the costs and the benefits of prophylactic interventions varies according to the extent to which clinical procedures, including laboratory testing, can estimate the level of cardiovascular risk. It can be argued that inappropriate cholesterol screening may have a negative effect on health economics and patient attitudes, but these problems appear easily surmountable. Techniques that enable the preclinical detection of CVD may help the process to strike a balance between public health initiatives that reduce the environmental factors responsible for the epidemic of CVD, and the strategies that are known to reduce event rates in high-risk individuals.

Abstract
Estimating the net benefits of dyslipidemia treatment is limited by the lack of comprehensive and standardized information on the preference for dyslipidemia and coronary heart disease. In a hospital-based study, we measured the health-related quality of life (HRQOL) of healthy participants without dyslipidemia (n = 307) and with dyslipidemia (n = 251) and patients with coronary heart disease (n = 320). Compared to the healthy participants without dyslipidemia, those with dyslipidemia reported lower adjusted mean scores on the Rating Scale (-2.8 points, P = 0.02) and the SF-36 General Health Scale (-3.3 points, P = 0.02). No differences were observed on the Time Trade-off and the Standard Gamble Scales. Coronary patients reported lower scores on all preference scales and most SF-36 scales. The causes of the small but real reduction in HRQOL reported by dyslipidemic individuals should be identified in order to optimize the net benefits of lipid therapy.

Abstract
CONTEXT Screening and treatment of lipid disorders in people at high risk for future coronary heart disease (CHD) events has gained wide acceptance, especially for patients with known CHD, but the proper role in people with low to medium risk is controversial. OBJECTIVE To examine the evidence about the benefits and harms of screening and treatment of lipid disorders in adults without known cardiovascular disease for the U.S. Preventive Services Task Force. DATA SOURCES We identified English-language articles on drug therapy, diet and exercise therapy, and screening for lipid disorders from comprehensive searches of the MEDLINE database from 1994 through July 1999. We used published systematic reviews, hand searching of relevant articles, the second Guide to Clinical Preventive Services, and extensive peer review to identify important older articles and to ensure completeness. DATA SYNTHESIS There is strong, direct evidence that drug therapy reduces CHD events, CHD mortality, and possibly total mortality in middle-aged men (35 to 65 years) with abnormal lipids and a potential risk of CHD events greater than 1% to 2% per year. Indirect evidence suggests that drug therapy is also effective in other adults with similar levels of risk. The evidence is insufficient about benefits and harms of treating men younger than 35 years and women younger than 45 years who have abnormal lipids but no other risk factors for heart disease and low risk for CHD events (less than 1% per year). Trials of diet therapy for primary prevention have led to long-term reductions in cholesterol of 3% to 6% but have not demonstrated a reduction in CHD events overall. Exercise programs that maintain or reduce body weight can produce short-term reductions in total cholesterol of 3% to 6%, but longer-term results in unselected populations have found smaller or no effect. To identify accurately people with abnormal lipids, at least two measurements of total cholesterol and high-density lipoprotein cholesterol are required. The role of measuring triglycerides and the optimal screening interval are unclear from the available evidence. CONCLUSIONS On the basis of the effectiveness of treatment, the availability of accurate and reliable tests, and the likelihood of identifying people with abnormal lipids and increased CHD risk, screening appears to be effective in middle-aged and older adults and in young adults with additional cardiovascular risk factors.

Abstract
We examined factors predicting knowledge of one's blood pressure, total cholesterol, and high-density lipoprotein levels (HDL) among older persons who reported a recent blood pressure or cholesterol test. Data come from a self-administered, health risk assessment that was mailed to health plan members, age 55 and older, in a Santa Barbara, California medical group. Despite their universal access to health care and high levels of reported compliance with preventive health care screening practices, 41%, 49%, and 77% of respondents reported that they did not know their blood pressure, cholesterol, or HDL levels, respectively. After controlling for potential confounders, age and low income were inversely associated with the respondents' ability to report each level. In addition, current smoking and obesity were inversely associated with self-reported knowledge of both cholesterol measures. Persons taking medication for hypertension or hypercholesterolemia were much more likely than those not taking medication to be able to report their blood pressure and cholesterol levels. Except for persons currently undergoing treatment for related conditions, these results suggest that a substantial proportion of the older persons at high risk for cardiovascular disease do not know their levels of these important biological risk factors. This lack of knowledge has important implications for public health education, and may hinder risk-reduction efforts among the elderly.

Abstract
OBJECTIVES To assess the feasibility of detecting new cases of heterozygous familial hypercholesterolaemia by using a nurse led genetic register. DESIGN Case finding among relatives of patients with familial hypercholesterolaemia. SETTING Two lipid clinics in central and south Manchester. SUBJECTS 259 (137 men and 122 women) probands and 285 first degree relatives. RESULTS Of the 200 first degree relatives tested, 121 (60%) had inherited familial hypercholesterolaemia. The newly diagnosed patients were younger than the probands and were generally detected before they had clinically overt atherosclerosis. Concentrations of serum cholesterol were, respectively, 8.4 (1.7 SD) mmol/l and 8.1 (1.9 SD) mmol/l in affected men and women and 5.6 (1.0 SD) mmol/l and 5.6 (1.1 SD) mmol/l in unaffected men and women. Screening for risk factors as recommended in recent guidelines for coronary heart disease prevention would have failed to identify most of the affected relatives in whom hypertension, diabetes mellitus, cigarette smoking, and obesity were uncommon. CONCLUSIONS By performing cholesterol tests on 200 relatives, 121 new patients with familial hypercholesterolaemia were discovered. Because 1 in 500 people in the United Kingdom are affected by this condition, to detect a similar number by population screening over 60 000 tests would be required, and only a few of these patients would have been detected had cholesterol testing been restricted to those with other risk factors for coronary heart disease. A case exists for organising a genetic register approach, linking lipid clinics nationally.

Abstract
BACKGROUND Type 2 diabetes is common, costly and often goes unrecognised for many years. When patients are diagnosed, the majority exhibit associated tissue damage or established cardiovascular risk. Evidence is accumulating that earlier detection and management of diabetes and related metabolic abnormalities may be beneficial. We aimed to develop and evaluate a score based on routinely collected information to identify people at risk of having undetected diabetes. METHODS A population-based sample of 1077 people, aged 40 to 64 years, without known diabetes, from a single Cambridgeshire general practice, underwent clinical assessment including an oral glucose tolerance test. In a separate 12-month study, 41 practices in southern England reported clinical details of patients aged 40 to 64 years with newly diagnosed Type 2 diabetes. A notional population was created by random selection and pooling of half of each dataset. Data were entered into a regression model to produce a formula predicting the risk of diabetes. The performance of this risk score in detecting diabetes was tested in an independent, randomly selected, population-based sample. RESULTS Age, gender, body mass index, steroid and antihypertensive medication, family and smoking history contributed to the score. In the test population at 72% specificity, the sensitivity of the score was 77% and likelihood ratio 2.76. The area under the receiver-operating characteristic curve was 80%. CONCLUSIONS A simple score, using only data that are routinely collected in general practice, can help identify those at risk of diabetes. This score could contribute to efficient earlier detection through case-finding or targeted screening.

Abstract
OBJECTIVE Our purpose was to determine the long-term effect on self-perceived health status and maternal perceptions of the offspring's health status after women had been labeled with a diagnosis of gestational diabetes. STUDY DESIGN We designed a mail survey of women who had participated in a large cohort study 3 to 5 years earlier. A tentative address list was developed for 139 women diagnosed with gestational diabetes and 406 matched controls; 33 and 89 questionnaires, respectively, were returned as "wrong address," but 106 case and 317 control addresses were potentially valid. The primary analysis compared cases and controls on the general health scale of the SF-36. Secondary outcomes included comparisons of the groups' mean results on a worry scale, ratings of the health of the child born in the index pregnancy, disability days, physician visits, diabetes preventive behaviors, and diabetes risk appraisal. RESULTS The usable response rates were 65 of 106 (61.3%) and 197 of 317 (62.1%), with no meaningful demographic differences found between respondents and nonrespondents. For general health, the mean score for cases was 68.9 (SD 22.34) vs 73.8 (SD 19.86) for controls, p = 0.05 (prespecified, one-tailed). After factors found to be independently related to health perception (age, race, birth place, and comorbidity) were controlled, the differences narrowed, with a mean score for cases of 70.09 versus 73.38 for controls, p = 0.11, two-tailed. Compared with controls, cases were more worried about their own health (p = 0.02, two-tailed), rated their children as less healthy (p = 0.005, two-tailed), and perceived themselves as more likely to have diabetes (p < 0.0001, two-tailed). CONCLUSION The diagnosis of gestational diabetes may lead to long-term changes in how women view their own health status and that of the child born during the affected pregnancy.

Abstract
OBJECTIVES To assess the psychological impact on women attending a familial ovarian cancer screening clinic. STUDY METHODS 157 women referred for screening completed an investigator designed questionnaire, the Spielberger State Trait Anxiety Scale and the Centre for Epidemiological Studies Depression Scale prior to the screening interview and an eight-item questionnaire post-assessment. RESULTS 95.4% saw the screening as valuable. Thirty-one point four percent of all patients scored about the cutoff point for depression. Sixteen percent exhibited high levels of anxiety. Fifty-six point four percent of patients accurately perceived their risk. Twenty-one point five percent of those who accurately perceived themselves as being at high risk had high anxiety and 40.6% reported significant depressive symptoms. Of the 26.5% of patients who overestimated their risks, 40.0% reported significant depressive symptoms and 22.6% were anxious. Of the 17.1% who minimized their risk, none were anxious (0.0%), and only 15.8% were depressed. CONCLUSION Attendees at a familial ovarian cancer screening clinic may have high levels of depression and anxiety.
