Article Citation - WoS: 20Citation - Scopus: 20Awareness, Treatment, Control of Hypertension, and Associated Factors: Results From a Turkish National Study(Taylor & Francis Inc, 2018) Dastan, Ilker; Erem, Ayşegül; Cetinkaya, VolkanObjective: Despite the fact that hypertension (HT) can be diagnosed and easily treated, it is frequently not handled well throughout the world, and as a developing country in Turkey. The objective of this study was to assess the factors associated with the awareness, treatment, and control of HT in Turkey. Methods: Data came from Chronic Diseases and Risk Factors Survey, comprising a nationally representative sample of 12,971 individuals, conducted by the Turkish Ministry of Health in 2011. HT was defined as having systolic/diastolic blood pressure (BP) at least 140/90 mmHg, usage of HT medicines, or having a previous diagnosis. Awareness, treated, and controlled HT were determined by questionnaires/BP measurements. Stepwise multiple logistic regression analysis was used to estimate associated factors. Results: The prevalence of HT was found to be 24.8%. Awareness, treatment, and control rates were 65%, 59%, and 30%, respectively. The risk factors for lack of awareness or treatment of HT were male gender, young age, rural residency, lower education, being employed, sedentary lifestyle, and less physical activity for women, unhealthy dietary habits for men, and modifiable risk factors, including smoking and drinking for men. Increasing age, low education for women, marital status subgroups within gender ( being single for men and being married for women), smoking and alcohol use for men, and diseases such as diabetes and obesity were also correlated with poor control of HT. Conclusion: This study recognized associated risk factors that may guide policies and interventions to enhance awareness, treatment, and control of HT in Turkey.Article A Consistent Statistical Test Based on Bivariate Random Samples(Hacettepe Univ, Fac Sci, 2023) Erem, Ayşegül; Bayramoğlu, İsmihanWe propose a consistent test for testing the distribution of bivariate random samples. The probability of type I, type II errors and probability of making no decisions under null and alternative hypotheses are obtained based on copula functions. The consistency of the proposed test is discussed under some null and alternative hypotheses. An unbiased, con-sistent estimator is proposed for probability of making no decision. Moreover, a simulation study is performed for showing the consistency of the proposed test for some well-known copulas such as independent, Clayton, Gumbel, Frank and Farlie-Gumb el-Morgenstern. Mathematics Subject Classification (2020). 62G30, 62H15Article Citation - WoS: 18Citation - Scopus: 23Urban and Rural Differences in Hypertension Risk Factors in Turkey(Aves, 2017) Dastan, Ilker; Erem, Ayşegül; Cetinkaya, VolkanObjective: Existing literature shows considerable regional differences in terms of hypertension (HT) prevalence in Turkey. The purpose of this study was to analyze some of the known HT risk factors contributing to the variations between urban and rural areas of Turkey in HT development. Methods: We used data from the 2011 Chronic Diseases and Risk Factors Survey that was conducted by the Turkish Ministry of Health on a representative sample of the Turkish adult population aged 20 years or more (n=16.227). HT was defined as having at least one of the following: a mean systolic/diastolic blood pressure of at least 140/90 mm Hg, a previously diagnosed disease, or use of antihypertensive medication. Stepwise multiple logistic regression analysis was used to estimate HT risk factors in urban and rural settings. Results: Although the HT prevalence was higher in rural areas (28.4%) than in urban areas (23.9%), in this study, urbanization was found to be a contributing factor in multivariate regression analysis. Furthermore, separate regressions for urban and rural settings revealed that age, obesity, diabetes, hyperlipidemia, and smoking were independently and positively associated (p<0.05) with HT in both settings, while marital status, employment type, mental health, and lifestyle patterns; nutritional habits; and amount of physical activity and sedentary time (p<0.05) were risk indicators in urban areas only. Conclusion: The findings of our study demonstrate that contributory factors show some variations between urban and rural settings, and on gender within each setting. Taking into account the variations between urban and rural areas in HT development may provide greater insight into the design of prevention strategies.Doctoral Thesis Bivariate Random Sequences and Exact and Asymptotic Distributions of Exceedance Statistics(İzmir Ekonomi Üniversitesi, 2017) Erem, Ayşegül; Bayramoğlu, İsmihanBu tezde, iki değişkenli rasgele değişken dizilerine dayalı rasgele bariyer modelleri incelenmiştir. Rasgele bariyer modelleri r' ıncı sıra istatistiğine ve eşleniğine dayalı olarak tanımlanmıştır. Aşan istatistiklere ilişkin sonlu ve asimptotik dağılımlar elde edilmiştir. Bu çalışmada sunulan aşan istatistiklerin dağılımları marjinal dağılımlara bağlı değildir ve yalnızca kapulalara bağlıdır. Bu iki değişkenli rasgele bariyer modellerinin sağlık ve hava kirliliğindeki uygulamaları ortaya konulmuştur.
