RESUMEN
BACKGROUND: Scientific evidence suggests an association between psoriasis and cardiovascular and metabolic diseases. However, there are hardly any sex-specific results from population-based studies reporting the prevalence of cardiovascular risk factors in patients with psoriasis and point estimates of the association between psoriasis and cardiovascular and metabolic disorders. OBJECTIVE: Aims are to evaluate the sex-specific prevalence of psoriasis and cardiovascular risk factors, and to estimate sex-specific associations between psoriasis and diabetes type 2 (DM) and metabolic syndrome (MetS). METHODS: We used data of 3723 participants (45-75 years, 54.1% women) without coronary heart disease and missing data (psoriasis, DM, MetS) from the Heinz Nixdorf Recall study. Standardized information on health outcomes and risk factors was assessed. We performed descriptive statistics and multiple regression analyses to calculate prevalence rate ratios (PR) and 95% confidence intervals (95% CI). RESULTS: The prevalence of psoriasis was 3.8% (n = 143), with no differences between sex. We observed more often metabolic and cardiovascular risk factors in women with psoriasis compared to women without psoriasis. Interestingly, in men, this pattern was partly reversed. Multiple regression analyses revealed distinctly elevated PRs for DM for both women and men with psoriasis (fully adjusted PR: 2.43; 95% CI: 1.17-5.07, resp. 2.09; 1.16-3.76). Regarding the MetS, the results were inconsistent, showing a positive association between psoriasis and MetS in women (1.84; 1.14-2.98), but a negative association in men, even though with a wide 95% CI (0.69; 0.42-1.12). CONCLUSION: The results of our cross-sectional, population-based analysis show a distinct association between psoriasis and DM, whereas for the MetS the results contrasted between men and women, translating in women with MetS showing a higher and in men a lower chance to be psoriatic. Our results emphasize the urgent need for sex-specific research, studying the effects of psoriasis on metabolic disorders as well as effective sex tailored prevention measures.

AIMS: Cross-sectional studies have consistently reported evidence for an association between diabetes and depressive disorders. However, only limited prospective studies have examined this association, reporting conflicting results. In a population-based cohort study, we compared cumulative incidences of diabetes between participants with and without high depressive symptoms. METHOD: We analysed the 5-year follow-up data from the German Heinz Nixdorf Recall study of 3547 participants without diabetes at baseline [mean age 58.8 (sd 7.6) years, 47.5% male]. Depressive symptoms were defined using the Centre for Epidemiologic Studies Depression scale (cut point ≥ 17). Diabetes (diagnosed or previously undetected) was identified by self-reported physician-diagnosed diabetes, medication and high blood glucose levels. We estimated 5-year cumulative incidences with 95% confidence intervals and fitted multiple logistic regression models to calculate the odds ratios, adjusted for age, sex, physical activity, smoking, living with or without partner, and educational level. RESULTS: The cumulative incidence of diabetes was 9.2% (95% CI 6.3-12.8) in participants with high depressive symptoms at baseline and 9.0% (95% CI 8.0-10.0) in participants without these symptoms. The age- and sex-adjusted odds ratio of diabetes in participants with depressive symptoms compared with those without was 1.13 [95% CI 0.77-1.68; fully adjusted 1.11 (95% CI 0.74-1.65)]. These results did not substantially change in several additional sensitivity analyses. CONCLUSION: Our study did not show a significantly increased risk of developing diabetes in individuals with high depressive symptoms compared with those without high depressive symptoms during a 5-year follow-up period.

AIMS/HYPOTHESIS: Atherosclerosis and cardiovascular diseases are often present at the time of diagnosis of type 2 diabetes mellitus. Whether subclinical atherosclerosis can be detected in the pre-diabetic (borderline fasting hyperglycemia) state is not clear. This study investigated the association of impaired fasting glucose (IFG) and coronary artery calcification (CAC), a marker of subclinical atherosclerosis, among participants without a history of coronary heart disease or manifest diabetes mellitus. METHODS: Study participants (aged 45-75 years) of the population-based Heinz Nixdorf Recall Study were categorised into those with normal fasting glucose (glucose <6.1 mmol/l) and those with IFG (glucose >or=6.1 to <7.0 mmol/l), excluding participants with a history of CHD or diabetes mellitus. CAC was assessed by electron-beam computed tomography, and risk factors were assessed by extended interviews, anthropometric measurements and laboratory tests. Various CAC cut-off points were used in multiple logistic and ordinal logistic regression models to estimate ORs and 95% CIs. RESULTS: Of the 2,184 participants, more men had IFG than did women (37% vs 22%). Participants with IFG showed a higher prevalence of CAC > 0 (men OR 1.90, 95% CI 1.33-2.70; women 1.63, 1.23-2.15). Risk factor adjustment weakened this association in both sexes (men 1.63, 1.12-1.36; women 1.26, 0.93-1.70). When the age- and sex-specific 75th percentile was used as the cut-off point for CAC, the association further decreased in men (1.10, 0.81-1.50), but became stronger in women (1.41, 1.02-1.94). CONCLUSIONS/INTERPRETATION: These data support the hypothesis that CAC is already present in the pre-diabetic state and that IFG has a modest and independent impact on the atherosclerotic process. Biological sex appears to modify the association between IFG and CAC.

AIMS: To estimate the association between depressive symptoms and Type 2 diabetes, as well as previously undetected diabetes, in a large population-based sample in Germany and to determine associated variables. METHODS: We used baseline data on 4595 participants (age 45-75 years, 50.2% women) from the German Heinz Nixdorf Recall study, a population-based, prospective cohort study which started in 2000. Diabetes mellitus was assessed by self report (physician diagnosis or medication), undiagnosed diabetes based on blood glucose levels. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) scale short form (cut-off >or= 15 points). We fitted multiple logistic regression models. RESULTS: The prevalence of diagnosed and previously undetected diabetes was 9.3% (95% confidence interval 8.2-11.6) and 7.6% (6.6-8.8) in men and 6.0% (5.1-7.1) and 3.2% (2.5-4.0) in women, respectively. Compared with non-diabetic women, the prevalence of depressive symptoms was not significantly different in diabetic women (age-adjusted odds ratio, 95% confidence interval 1.48; 0.98-2.24) and women with undiagnosed diabetes (0.67; 0.33-1.36). In men, the prevalence of depressive symptoms tended to be lower in diabetic than in non-diabetic subjects (0.62; 0.35-1.09), but the depressive symptoms were significantly less frequent in men with undiagnosed diabetes (0.30; 0.13-0.70). The pattern remained after further adjustment. Significant associations with depressive symptoms were found for co-morbidities and living without a partner in both women and in men, and for body mass index and activity level in women only. CONCLUSIONS: After adjustment for relevant covariates, the association between depressive symptoms and Type 2 diabetes was heterogenous in our population-based study. In subjects with undiagnosed diabetes, however, depressive symptoms were less frequent in men. Co-morbidities and psychosocial conditions are strongly associated with depressive symptoms.

OBJECTIVE: For the first time, this population-based study sought to analyze healthcare utilization and associated costs in people with normal fasting glycemia (NFG), impaired fasting glycemia (IFG), as well as previously undetected diabetes and previously diagnosed diabetes linking data from the prospective German Heinz Nixdorf Recall (HNR) study with individual claims data from German statutory health insurances. RESEARCH DESIGN AND METHODS: A total of 1709 participants of the HNR 5-year follow-up (mean age (SD) 64.9 (7.5) years, 44.5% men) were included in the study. Age-standardized and sex-standardized healthcare utilization and associated costs (reported as for the year 2008, perspective of the statutory health insurance) were stratified by diabetes stage defined by the participants' self-report and fasting plasma glucose values. Cost ratios (CRs) were estimated using two-part regression models, adjusting for age, sex, sociodemographic variables and comorbidity. RESULTS: The mean total direct healthcare costs for previously diagnosed diabetes, previously undetected diabetes, IFG, and NFG were 2761 (95% CI 2378 to 3268), 2210 (1483 to 4279), 2035 (1732 to 2486) and 1810 (1634 to 2035), respectively. Corresponding age-adjusted and sex-adjusted CRs were 1.53 (1.30 to 1.80), 1.16 (0.91 to 1.47), and 1.09 (0.95 to 1.25) (reference: NFG). Inpatient, outpatient and medication costs varied in order between people with IFG and those with previously undetected diabetes. CONCLUSIONS: The study provides claims-based detailed cost data in well-defined glucose metabolism subgroups. CRs of individuals with IFG and previously undetected diabetes were surprisingly low. Data are important for the model-based evaluation of screening programs and interventions that are aimed either to prevent diabetes onset or to improve diabetes therapy as well.
RESUMEN
BACKGROUND: The main causes of congestive heart failure (CHF) are coronary artery disease (CAD) and arterial hypertension. Coronary artery calcification (CAC) evidencing coronary atherosclerosis may occur prior to clinical CAD. The aim of our study was to assess the association between CAC as a sign of subclinical CAD and CHF in a general unselected population. METHODS: Participants of the Heinz Nixdorf Recall Study without known CAD but with known CHF as defined by a physicians' diagnosis of CHF and dyspnea were identified. B-natriuretic peptide was measured and an exercise stress test was performed as possible. Cardiovascular risk factors and the EBCT-based CAC Agatston score were determined. RESULTS: Those 105/4,230 subjects (2.5%) with CHF (age 65 +/- 7 years, 44% males), had higher brain natriuretic peptide (BNP) levels (median BNP 36.8 [16.5-70.1] vs. 17.6 [9.5-31.7] pg/ml, p<0.01) and lower exercise capacity (108.7 +/- 39.4 vs. 130.0 +/- 40.7 W, p<0.01) than those without. CAC in subjects with CHF was significantly higher than in those without (median CAC 64.7 [8.5-312.3] vs. 11.6 [0-109.8], p<0.01). In univariate analysis, CAC-burden after logarithmic transformation according to log(2)(CAC + 1) showed a significant association with the presence of CHF (odds ratio (OR) (95% CI): 1.16 (1.1-1.23), p<0.0001). Adjustment for age and sex (OR 1.11 (1.04-1.18), p<0.001), additional Framingham risk score (OR 1.09 (1.02-1.16), p = 0.015), and additional cardiovascular medication (OR 1.07 (0.998-1.14), p = 0.058) attenuated this association. Age, systolic blood pressure, antihypertensive medication and increased body mass index also remained significantly associated with presence of CHF in the full multivariate model. CONCLUSION: The observed association between CAC and CHF in persons without clinically overt CAD is partly determined by risk factors that are involved in the natural history of both CAC and CHF. Whether CAC has a role to identify subjects at risk of future CHF remains to be determined using follow-up analyses.
