[Turkish Adult Risk Factor survey 2014: Overall mortality and coronary disease incidence in Turkey's geographic regions]. / TEKHARF 2014 taramasi ve Türkiye'de cografi bölgelere göre ölüm orani ile koroner hastalik insidansi.

OBJECTIVE: This study aimed to examine the overall and coronary mortality in the 2014 Turkish Adult Risk Factor Study survey, and the distribution of cumulative mortality and incident coronary heart disease (CHD) across 7 geographic regions. METHODS: Information on mode of death was appropriately obtained. Information collected from survivors was based on history, examination of the cardiovascular system and the Minnesota coding of electrocardiograms. Cox regression analyses were performed. RESULTS: Of the 1.323 participants to be surveyed, 87 were lost to follow-up, 753 examined, and 35 ascertained as deceased. In 448 subjects, verbal information alone was obtained regarding health status. Nineteen deaths were of coronary and cerebrovascular origin. Cumulative 24-year assessment of the entire cohort in the age bracket 45-74 years disclosed high coronary mortality, at 7.3 per 1000 person-years in men and 3.8 in women, and recorded a limited decline of 18% since the year 2000. Age-adjusted Cox regression analysis, comprising 614 deaths and 482 incident CHD over a follow-up of 9.6 years, revealed higher mortality rates in the Mediterranean region and in men in the Black Sea and Marmara regions. The age-adjusted CHD incidence was significantly higher in males of the Mediterranean and females of the Southeast regions. An estimated 400-420.000 incident CHD cases develop currently each year in Turkey. CONCLUSION: The generally high age-adjusted overall mortality in Turkey displays significant differences across geographic regions. Age-adjusted CHD incidence is not regressing sufficiently, and is especially high among men of the Mediterranean and women of the Southeast regions.

Determinants of obstructive sleep apnea syndrome: Pro-inflammatory state and dysfunction of high-density lipoprotein.

OBJECTIVE: The goal of this study was to determine variables preceding and predicting incident obstructive sleep apnea syndrome (OSAS) in the population at large. METHODS: Anthropometric, lipid, and non-lipid variables in participants with newly developing OSAS (n = 131) were compared with those of a cohort sample (n = 2615) of the Turkish Adult Risk Factor study. Available values preceding (by a median of 32 mo) the development of OSAS were used in multivariable Cox regression models. RESULTS: Significant determinants of OSAS assessed by group differences were waist/neck circumference and fibrinogen. Fasting triacylglycerols, systolic blood pressure, and C-reactive protein in men and low sex hormone-binding globulin and elevated homeostatic model assessment in women were further significant covariates. Cox regression analysis for the risk of incident OSAS confirmed the independent predictive value of central obesity measures, especially neck circumference (having a twofold hazard ratio) and younger age. Age-adjusted former smoking status and-compared with the lowest tertile-the upper two tertiles of fibrinogen (relative risk = 1.66, 95% confidence interval: 1.05-2.63) were significant predictors. Elevated triacylglycerols in males and high apolipoprotein B and lowest high-density lipoprotein cholesterol tertile in females also predicted subsequent OSAS. Systolic blood pressure and total cholesterol did not prove to be independent predictors in multivariable adjusted Cox models in which partial sex-dependent independence of obesity measures of the previously stated five variables was essentially retained. CONCLUSIONS: An enhanced pro-inflammatory state appeared to be the underlying pathophysiologic mechanism for OSAS, whereas in men, the added factor of high-density lipoprotein dysfunction was suggested. Because it contributes to the pro-inflammatory state, discontinuance of smoking was another further significant predictor of OSAS.

Fatty liver disease: Disparate predictive ability for cardiometabolic risk and all-cause mortality.

AIM: To assess the association of a surrogate of fatty liver disease (FLD) with incident type-2 diabetes, coronary heart disease, and all-cause mortality. METHODS: In a prospective population-based study on 1822 middle-aged adults, stratified to gender, we used an algorithm of fatty liver index (FLI) to identify associations with outcomes. An index ≥ 60 indicated the presence of FLD. In Cox regression models, adjusted for age, smoking status, high-density lipoprotein cholesterol, and systolic blood pressure, we assessed the predictive value of FLI for incident diabetes, coronary heart disease (CHD), and all-cause mortality. RESULTS: At a mean 8 year follow-up, 218 and 285 incident cases of diabetes and CHD, respectively, and 193 deaths were recorded. FLD was significantly associated in each gender with blood pressure, total cholesterol, apolipoprotein B, uric acid, and C-reactive protein; weakly with fasting glucose; and inversely with high-density lipoprotein-cholesterol and sex hormone-binding globulin. In adjusted Cox models, FLD was (with a 5-fold HR) the major determinant of diabetes development. Analyses further disclosed significant independent prediction of CHD by FLD in combined gender [hazard ratio (HR) = 1.72, 95% confidence interval (CI): 1.17-2.53] and men (HR = 2.35, 95%CI: 1.25-4.43). Similarly-adjusted models for all-cause mortality proved, however, not to confer risk, except for a tendency in prediabetics and diabetic women. CONCLUSION: A surrogate of FLD conferred significant high risk of diabetes and coronary heart disease, independent of some metabolic syndrome traits. All-cause mortality was not associated with FLD, except likely in the prediabetic state. Such a FLI may reliably be used in epidemiologic studies.
