Prediabetes and deprivation: A couple at high risk of diabetes.

AIM: The higher prevalence of diabetes in deprived populations is well documented but little is known about the risk of diabetes associated with deprivation among pre-diabetic subjects. The aim of the study was to evaluate the risk of diabetes in a population of deprived pre-diabetic patients. METHODS: 2743 pre-diabetic subjects identified using the American Diabetes Association (ADA) criteria, 16 to 85 years old, 1656 non-deprived and 1087 deprived, had at least two health check-ups at an interval of 4.95 (2.04) vs 3.20 (1.71) years, P<0.0001, respectively. At the first visit, socioeconomic status was assessed using the EPICES score to differentiate deprived and non-deprived subjects. RESULTS: At the second visit, the prevalence of overt diabetes was 9.5% among deprived vs 5.1% in the non-deprived group (P<0.001). After adjustment on confounding factors, deprivation was found independently associated with occurrence of diabetes [1.70 (1.15-2.51), P=0.01]. Beyond social deprivation, Fasting Plasma Glucose and waist circumference were the main independent predictors of new-onset diabetes. CONCLUSION: After 4 years of follow-up, among subjects with prediabetes, prevalence of diabetes was twice as high among deprived compared with non-deprived subjects. Deprived populations with pre-diabetes may require specific public health approaches to avoid the occurrence of overt diabetes.

Association between depression and anemia in otherwise healthy adults.

OBJECTIVE: It remains debated whether anemia is associated with depression, independently of physical health factors. We report a large-scale cross-sectional study examining this association in adults free of chronic disease and medication from the general population. METHOD: Hemoglobin levels were measured among 44 173 healthy participants [63% men; mean [standard deviation] age = 38.4 (11.1) years] from the 'Investigations Préventives et Cliniques' (IPC) cohort study. Depression was measured with the Questionnaire of Depression 2nd version, Abridged. Logistic regression analyses were performed to examine the association between anemia and depression, while adjusting for a wide range of sociodemographic characteristics and health-related factors (i.e., sex, age, living status, education level, occupational status, alcohol intake, smoking status, physical activity, and body mass index). RESULTS: Depressed participants were significantly more likely to have anemia compared to non-depressed participants, even after adjustment for sociodemographic and health-related variables [odds ratio = 1.36; 95% confidence interval = (1.18; 1.57)]. Anemia prevalence increased with depression severity, suggesting a dose-response relationship (P for trend <0.001). CONCLUSION: In healthy adults from the general population, we found a significant and robust association between depression and anemia. Further studies are needed to assess the longitudinal relationship between both conditions and determine the mechanisms underlying this association.

Oral health in patients treated by positive airway pressure for obstructive sleep apnea: a population-based case-control study.

PURPOSE: Recent epidemiological evidence suggests that patients with obstructive sleep apnea (OSA) have an increased risk of periodontal disease. Little is known about the oral health of OSA patients treated by continuous or bi-level positive airway pressure (CPAP/BiPAP). The aim of this population-based case-control study was to compare oral health variables (amount of plaque, calculus, gingival inflammation, and masticatory function) between CPAP/BiPAP users and control subjects. METHODS: The study population was retrieved from a French cohort examined between 2012 and 2013 at the Centre d'Investigations Préventives et Cliniques of Paris. Cases were selected if they reported to be treated by CPAP/BiPAP; controls were age-, gender-, and BMI-matched based on a 1:2 ratio. Univariate and logistic regression analyses were performed for group comparisons. RESULTS: Over a total of 20,436 subjects, 287 CPAP/BiPAP users (mean age (SD) 57.6 years (11.5); 76.3 % males) who underwent medical and dental examinations were compared with 574 matched controls (no OSA, no CPAP/BiPAP). CPAP/BiPAP users reported significantly higher prevalence of diabetes (15.6 vs. 10.3 %; p = 0.012; odds ratio (OR) 1.68), history of hypertension (36.5 vs. 26.1 %; p = 0.003; OR 1.62), cardiovascular diseases (14.1 vs. 8.8 %; p = 0.029; OR 1.69), and sleep complaints (59 vs. 34.4 %; p = 0.0001; OR 2.75). CPAP/BiPAP users also showed higher levels of depression and stress compared to controls. However, no group difference was observed for the amount of dental plaque, calculus, gingival inflammation, and masticatory function. CONCLUSION: Oral health of OSA patients treated by CPAP/BiPAP is comparable to that of matched controls in terms of amount of plaque, gingival inflammation, and masticatory function.

Adapted educational health program among deprived subjects with prediabetes.

AIMS: Assess the feasibility and benefit of a health educational program on global metabolic status in prediabetic deprived subjects. DESIGN: Case control study. METHODS: 693 subjects (466 men, 227 women), aged 16 to 95 years with prediabetes and low socioeconomic status, consulting at the IPC Center were included between September 2015 and June 2016. Subjects were invited to participate in 4 workshops (2 nutrition, 2 physical activities). One year after their inclusion (visit 1), they were offered a second health check-up (visit 2). Participants were classified into 3 groups: 1) Intervention group (INTG, N=133): complete process 2) Control group (CG, N=415): Only a second health check-up, no workshop participation; 3) Abandoned group (AG, N=145). All groups were compared. RESULTS: After considered confounding factors, fasting blood glucose and SBP levels variation between visit 1 and visit 2 differed significantly between the CG and INTG. In the INTG with higher diminution of fasting glucose, 90% reported eating healthy food since nutrition workshop and 51%. reached objectives (The same trend was observed for physical activity. CONCLUSION: An educational program among deprived prediabetic tended to limit fasting glucose increment, improve metabolic status and encourage healthy lifestyle despite difficulties in convincing subjects to participate.

Central artery pulse pressure in end-stage renal disease: the roles of aortic diameter, aortic stiffness and wave reflection.

In elderly subjects and patients with end-stage renal disease (ESRD), carotid pulse pressure (PP) is an independent and significant predictor of cardiovascular (CV) risk. Whereas in the elderly carotid diameter, but not carotid stiffness, is an associated CV risk factor, an opposite CV risk pattern was observed in ESRD patients that was associated with stiffness. Whether in ESRD patients arterial diameter, stiffness or both are involved in the mechanism(s) of increased carotid PP has never been investigated. Nondiabetic ESRD patients (n = 144) were compared with 57 control subjects matched for age, sex and mean blood pressure, but with higher brachial and carotid PP. Noninvasive echo-Doppler techniques and pulse wave velocity (PWV) and pulse wave analysis were used to evaluate cardiac and carotid arterial structures and functions using multiple stepwise regressions. In controls, carotid PP was associated only with stroke volume, arterial wave reflections and aortic PWV, but not aortic diameter. In ESRD patients, it was associated with wave reflections, aortic PWV, stroke volume and higher aortic diameter. In ESRD patients and controls, elevated carotid PP mainly reflected increased aortic PWV and earlier wave reflections. Aortic diameter had an impact only on ESRD patients, where it compensated for enhanced aortic stiffness and the more pronounced effect of reflected waves. This hemodynamic profile differs consistently from that in elderly subjects of the general population and selectively influences CV risk and drug treatment.

Vascular risk factors and morphometric data in cervical artery dissection: a case-control study.

BACKGROUND: Limited knowledge exists on vascular risk factors, body height and weight in patients with spontaneous cervical artery dissection (sCAD). PATIENTS AND METHODS: In this case-control study, major vascular risk factors, body weight, body height and body mass index (BMI) of 239 patients obtained from a prospective hospital-based sCAD registry were compared with 516 age- and sex-matched healthy controls undergoing systematic health examinations in the Clinical and Preventive Investigations Center, Paris. Gender-specific analyses were performed. RESULTS: The mean body height was higher in sCAD patients than in controls (171.3 cm (SD 8.6) vs 167.7 cm (8.9); p<0.0001) and sCAD patients had a significantly lower mean body weight (67.5 (12.2) kg vs 69.3 (14.6) kg; p<0.001) and mean BMI (22.9 (3.3) kg/m2 vs 24.5 (4.2) kg/m2; p<0.0001) than controls. The overall frequency of hypertension, diabetes, current smoking, past smoking and hypercholesterolaemia did not differ significantly between sCAD patients and controls. The mean total plasma cholesterol level was identical in both groups (5.5 mmol/l, SD 1.1). Gender specific subgroup analyses showed similar results for men and women. CONCLUSION: Patients with sCAD had a higher body height and a lower body weight and BMI than controls, while major vascular risk factors were similar in sCAD patients and controls.

Body Silhouette Trajectories Over the Lifespan and Insomnia Symptoms: The Paris Prospective Study 3.

Insomnia symptoms are highly prevalent and associated with several adverse medical conditions, but only few determinants, including non-modifiable ones, have been highlighted. We investigated associations between body silhouette trajectories over the lifespan and insomnia symptoms in adulthood. From a community-based study, 7 496 men and women aged 50-75 years recalled their body silhouette at age 8, 15, 25, 35 and 45, and rated the frequency of insomnia symptoms on a standardized sleep questionnaire. An Epworth Sleepiness Scale ≥11 defined excessive daytime sleepiness (EDS). Using a group-based trajectory modeling, we identified five body silhouette trajectories: a 'lean-stable' (32.7%), a 'heavy-stable' (8.1%), a 'moderate-stable' (32.5%), a 'lean-increase' (11%) and a 'lean-marked increase' (15.7%) trajectory. In multivariate logistic regression, compared to the 'lean-stable' trajectory, the 'lean-marked increase' and 'heavy-stable' trajectories were associated with a significant increased odd of having ≥1 insomnia symptoms as compared to none and of having a proxy for insomnia disorder (≥1 insomnia symptom and EDS). The association with the 'lean-marked increase' trajectory' was independent from body mass index measured at study recruitment. In conclusion, increasing body silhouette over the lifespan is associated with insomnia symptoms in adulthood, emphasizing the importance of weight gain prevention during the entire lifespan.

Ageing and blood pressure modulate the relationship between metabolic syndrome and aortic stiffness in never-treated essential hypertensive patients. A comparative study.

OBJECTIVE: The aim of this study was to evaluate the impact of the metabolic syndrome (MS) and its components as defined by the National Cholesterol Education Program Adult Treatment Panel III on arterial stiffness in untreated hypertensive patients. METHODS: This was a cross sectional multi-center study performed in 46 healthcare centers, from 14 countries involved in the Complior study. Four hundred and forty patients (55% male) aged 18-73 years, with untreated essential hypertension were selected at inclusion. All patients underwent a full evaluation for all the risk factors representing the MS and an assessment of arterial stiffness using automatic measurement of carotid-femoral pulse wave velocity (PWV). RESULTS: In the overall population significant correlations were found, respectively, between PWV, MS (R=0.2, P<0.001) and gender (R=0.11, P=0.023) where PWV was higher in women. After adjustment for age and systolic blood pressure (SBP), analysis of covariance showed an independent effect of the MS on PWV, this effect increased with ageing and SBP especially after 47 years (age median, P=0.0047). Moreover, increase of mean PWV was highly associated with the number of MS factors in global population (P<0.001). These findings suggest that MS leads to early arterial wall ageing. CONCLUSIONS: Presence of MS induces an increase of arterial stiffness in untreated hypertensive patients independently from age and SBP. The increase of PWV is proportional to number of risk factors and affects principally patients after mid-age of 47 years where MS has ageing effects on arterial stiffness.

[Number and use of home blood pressure devices in France in 2004 and 2006 (FLAHS 2006)]. / Possession et usage des appareils d'automesure en France en 2004 et 2006. Enquête FLAHS 2006.

OBJECTIVES: To estimate the number and the using modalities of devices for home blood pressure (HBP) measurements in the French population in 2006 and to evaluate the trend of these data over the past two Years. METHODS: The French League Against Hypertension Surveys have been performed both in 2004 and 2006 (FLAHS-2006) by an independent company (TNS-SOFRES) within a representative sample of French population older than 35 and living in metropolitan France. The surveys involved 3707 and 3389 subjects, respectively. A questionnaire evaluating ownership, kind and using modalities of HBP device was given. Subjects who declared taking an antihypertensive medication were classified as treated hypertensive patients. The data from the INSEE census performed in1999 allowed for an estimate of the total number of HBP devices owned by French people. RESULTS: In 2006, 19% of the French population above the age of 35 years owned a HBP device, a rate reaching 36% in treated hypertensives versus 11% in the rest of the population (p<0.001). In 2004, the ownership rates were 24% and 7%, respectively. It could be estimated that about 6 million HBP devices were owned by French people in 2006, meaning an increase of 2 million devices, as compared with 2004 survey. 53% of BP devices were equipped with an arm cuff in 2006, versus 33% only, in 2004. Device purchase has been made in 2006 either in a pharmacy (39%), or in a hypermarket (7%), or through the web (3%); they were given as a gift in 39%. Device use was indicated as regular by 30% of hypertensive patients and 23% of the rest of the people. Giving up was observed in 7% and 15%, respectively. CONCLUSION: In 2006, about 6 million HBP devices are owned by French people; the rate of treated hypertensives owning a HBP device is 1/3. The huge increase in the number of HBP devices from 2004 to 2006 suggests that the recommendations of the French "Haute Autorité de Santé" as well as the national programs about HBP measurement have had a real impact on the use of this technique in France.

Atherosclerosis versus arterial stiffness in advanced renal failure.

Epidemiological as well as clinical studies have shown that regardless of the severity of renal impairment the cardiovascular mortality in renal disease patients is very high compared to the general population. In uremia, cardiovascular disease is a combination of atherosclerosis, characterized by the presence of highly calcified plaques, and arteriosclerosis, an arterial wall alteration in response to both hemodynamic changes and humoral modifications such as inflammation or calcium-phosphate imbalance. Vascular endothelium, recognized as a large and complex endocrine organ strategically located between the wall of the blood vessel and the blood stream, could be the link between these two processes evolving during the same course.
