  Abstract

  Background and objectives: Depression is the most common cause of disability caused by diseases in the world. Having physical activity is a solution for reducing depression. This study was conducted to determine the causes of depression and its related factors.

  Methods: In this descriptive-analytical study, 266 female students participated in the study selected by random stratified sampling. The data were collected with demographic questionnaires, the Beck Depression Inventory, and the International Physical Activity Questionnaire (IPAQ) and the body composition was measured with the body analyzer machine and entered into the SPSS software. To examine the effect of physical activity on depression, a logistic regression model was used with adjusting the effect of the likely confounding variables.

  Results: The mean age of the participants was 22.15 ± 2.4. According to the Beck Depression Inventory, 24.8% (66 individuals) suffered from depression and 69.5% (185 individuals) were healthy and 5.6% (15 persons) were missing from study. The results did not show a significant difference between depression and being local or nonlocal, BMI and the income level. But there was a significant difference between the healthy and the depressed group with regard to physical activity ( P=0.03). Physical activity at recommended levels showed an inverse relationship with depression of students so that students who have the recommended levels of physical activity get the 44% lower chance to be in the depressed group against students who have been low level of physical activity (OR=0.56, 95% CI:0.31-0.99, P=0.046).

  Conclusion: Due to the effect of physical activity on reducing depression, providing sport facilities, recommending people to increase their physical activity and culture making in the society can serve as constructive solutions to improving the psychological health and preventing depression in the society.

Background & Objective: Using internet have had a significant impact on the lifestyle changes of internet clients which can affect their health. The aim of this study was to survey the relationship between lifestyle related to internet with loneliness and social support of the internet clients in Ilam University of medical sciences.

Methods: This study was a cross sectional study which was performed in 2014 on 400 university students and personnel of Ilam University of medical sciences using stratified random sampling method.Data collection instrument was a questionnaire comprising of four sections: demographic information, lifestyle related to internet questionnaire , loneliness and social supports questionnaires.All data were analyzed using SPSS software by Mann Withney and Kruscall- Wallis tests and linear regression test.

Results: The linear regression results showed that there was a significant relationship between loneliness and lifestyle related to the internet, gender, marital status, occupational statues and age (P<0.01). There was also a significant relationship between social support and lifestyle related to the internet and age (P<0/05). The results showed that there was a significant relationship between loneliness and social support with marital status, educational degree and internet usage (P<0/01).

Conclusion: According to the significant relation between loneliness and social support with the lifestyle related to the internet, and regarding the inevitability of Internet, it seems more supporting the students and implementing the educational programs for university clients about suitable using of internet is necessary.

Background and Objective: The industrial development along with the rising in human population has led to releasing considerable hazardous materials such as heavy metals into the environment. Environmental pollution by heavy metals can in turn threaten the human health. Therefore, the aim of this study was to assess the concentration levels of some heavy metals including; Cd, Pb, Cr and Cu, as well as to estimate the physico-chemical parameters of drinking water distribution network of Sanandaj city in 2014.

Methods: In order to accomplish the present descriptive study, 18 samples were collected from the water distribution network of Sanandaj during 2014. The level of heavy metals were assayed by using a graphite furnace atomic absorption (Phoenix 986). The standard approaches mentioned in the standard method book were used to measure the fluoride, nitrate and hardness of water. The Pearson Correlation test was used to estimate the association between parameters.

Results: The mean concentrations of Cd, Pb, Cr and Cu were found to be 0.0004, 0.011, 0.03, 0.3 mg/L respectively. Moreover, the mean levels of fluoride, nitrate, and total hardness were 0.11, 6.57, and 166 mg/L respectively. The level of Hazard Quotient in this study was lower than 1 (HQ < 1).

Conclusion: The concentration of all heavy metals in this study were lower than the national and international thresholds of drinking water. It is concluded that Sanandaj drinking water is safe to drink concerning health issues.
