The association of self-esteem, depression and body satisfaction with obesity among Turkish adolescents

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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.</p> <p>Conclusion</p> <p>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.</p

SWELL BEHAVIOR OF ARID CLIMATE SHALES FROM SAUDI-ARABIA

Arid and hot climatic conditions influence the development of surficial (superficial) sediments by aggravating the desiccation and weathering processes. Such environmental factors promote the occurrence of expansive soils in the Middle East. This study deals with the nature and extent of expansive soil problems in major development areas of Saudi Arabia where severe damage has been experienced in numerous projects. The expansive soils primarily consist of shales of Tertiary age which occur in a narrow strip adjacent to the western boundary of the Arabian Shield. Profile characteristics, geotechnical properties and swell behaviour of the shales are presented. Model equations were developed by nonlinear regression analysis for prediction of swell parameters from easily determined geotechnical indices
