    Risk factors for depression in the first postnatal year: A Turkish study
    (2005) Inandi T.; Bugdayci R.; Dundar P.; Sumer H.; Sasmaz T.
    Background: The aim of the study was to identify risk factors for depression and to estimate its prevalence in postnatal mothers. Methods: This cross-sectional and multi-centre study was carried out on 1,350 Turkish women in their first postnatal year. Measures included a structured questionnaire and the Turkish version of the Edinburgh Postnatal Depression Scale (EPDS). Results: Of the women, 31.1% had as core of 13 or higher on the EPDS. The mean score and standard deviation was 9.8±5.7. In the multivariate analysis, EPDS scores were significantly associated with economic status, access to support from family members and close friends, emotional distress at the pregnancy, whether the pregnancy was planned, health problems during pregnancy, the perceived standard of baby care after delivery, and mental disorder before and during pregnancy. Conclusion: The prevalence of EPDS-based depression among Turkish women in postnatal the period was high, and was associated with several social, economic and demographical factors. © Springer-Verlag 2005.

    The association of self-esteem, depression and body satisfaction with obesity among Turkish adolescents
    (2007) Ozmen D.; Ozmen E.; Ergin D.; Cetinkaya A.; Sen N.; Dundar P.; Taskin E.O.
    Background. The purpose of this study was to determine the prevalence of overweight and obesity and to examine the effects of actual weight status, perceived weight status and body satisfaction on self-esteem and depression in a high school population in Turkey. Methods. A cross-sectional survey of 2101 tenth-grade Turkish adolescents aged 15-18 was conducted. Body mass index (BMI) was calculated using weight and height measures. The overweight and obesity were based on the age- and gender-spesific BMI cut-off points of the International Obesity Task Force values. Self-esteem was measured using the Rosenberg Self-Esteem Scale, and depression was measured using Children's Depression Inventory. Logistic regression analysis was used to examine relationships among the variables. Results. Based on BMI cut-off points, 9.0% of the students were overweight and 1.1% were obese. Logistic regression analysis indicated that (1) being male and being from a higher socio-economical level were important in the prediction of overweight based on BMI; (2) being female and being from a higher socio-economical level were important in the prediction of perceived overweight; (3) being female was important in the prediction of body dissatisfaction; (4) body dissatisfaction was related to low self-esteem and depression, perceived overweight was related only to low self-esteem but actual overweight was not related to low self-esteem and depression in adolescents. Conclusion. The results of this study suggest that school-based adolescents in urban Turkey have a lower risk of overweight and obesity than adolescents in developed countries. The findings of this study suggest that psychological well-being of adolescents is more related to body satisfaction than actual and perceived weight status is. © 2007 Ozmen et al; licensee BioMed Central Ltd.

    Violence against women: The perspective of academic women
    (2010) Kalaca S.; Dundar P.
    Background. Opinion surveys about potential causes of violence against women (VAW) are uncommon. This study explores academic women's opinions about VAW and the ways of reducing violence. Methods. Quantitative and qualitative methods were used in this descriptive study. One hundred-and-fifteen academicians participated in the study from two universities. A questionnaire was used regarding the definition and the causes of VAW, the risk groups and opinions about the solutions. Additionally, two authors interviewed 8 academicians from universities other than that of the interviewing author. Results. Academicians discussed the problem from the perspective of "gender-based violence" rather than "family violence". The majority of the participants stated that nonworking women of low socioeconomic status are most at risk for VAW. They indicated that psychological violence is more prevalent against educated women, whilst physical violence is more likely to occur against uneducated and nonworking women. Perpetrator related factors were the most frequently stated causes of VAW. Thirty-five percent of the academicians defined themselves as at risk of some act of VAW. Recommendations for actions against violence were empowerment of women, increasing the educational levels in the society, and legal measures. Conclusions. Academic women introduced an ecological approach for the explanation of VAW by stressing the importance of taking into account the global context of the occurrence of VAW. Similar studies with various community members -including men- will help to define targeted interventions. © 2010 Kalaca and Dundar; licensee BioMed Central Ltd.

    Is genetic screening necessary for determining the possibility of venous thromboembolism in cancer patients?
    (2012) Onur E.; Kurdal A.T.; Tugrul B.; Iskesen I.; Dundar P.; Taneli F.; Ulman C.; Var A.
    To determine the risk of an association with some genetic polymorphisms involved in venous thromboembolism (VTE) gene variations (FVL, FV H1299R, FII G20210A, MTHFR C677T, MTHFR A1298C, PAI-1 4G/5G,β-fibrinogen -455 G ] A, FXIII Val34Leu and GpIIIa HPA-1a) in cancer patients. Subjects and Methods: Among 78 cancer patients, 28 who had proven first episode of VTE were selected as the patient group, with 50 control samples selected from age-, sex- and body mass index-matched healthy volunteers (healthy group). The differences in frequency of genetic polymorphisms were found to be statistically insignificant between these two groups. Results: Logistic regression analysis after adjustment for age, sex, smoking and hypertension showed no difference. The screened mutations of these genes were not significantly associated with VTE risk. Conclusion: There is no possible benefit from genetic screening tests regarding VTE in cancer patients. © 2011 S. Karger AG, Basel.

    The Average Covering Number of a Graph
    (2013) Dogan D.; Dundar P.
    There are occasions when an average value of a graph parameter gives more useful information than the basic global value. In this paper, we introduce the concept of the average covering number of a graph (the covering number of a graph is the minimum number of vertices in a set with the property that every edge has a vertex in the set). We establish relationships between the average covering number and some other graph parameters, find the extreme values of the average covering number among all graphs of a given order, and find the average covering number for some families of graphs. © 2013 Derya Dogan and Pinar Dundar.
