Introduction: Bladder cancer is regarded as the most common urinary malignancy in the world. As other cancers, its incidence has increased in recent years. Hence, the present study was conducted to investigate the relationship between smoking and opium and bladder cancer in residents of Yazd province.

Materials and Methods: This case-control study was performed on 200 patients with bladder cancer and 200 matched healthy individuals in Yazd province. Research data was gathered through interview and administration of a researcher-made questionnaire.  Furthermore, chi-square and regression tests were carried out with SPSS software (version 18).

Results: The mean and standard deviation of age in case and control groups were reported to be 61.54 ± 13.61 and 61.45 ± 13.3 respectively. Education level, type of oil consumed, weekly frequency of smoking and fried foods, white meat, red meat consumption involve the predictive factors for bladder cancer; as consumption of hydrogenated fats, animal fats, fried foods more than 4 times per week and red meat had (OR=1.31;95% CL,0.63-2.71), (OR= 6.32;95% CL,2.03-19.8), (OR=2.86;95% CL,1.2-6.8) and (OR=51.18;95% CL,14.78-177.03) times greater risk for bladder cancer respectively and also low education level. White meat intake had a protective effect. Moreover, in line with increasing number of cigarettes per day, the risk of bladder cancer increased.

Conclusion: The findings of the present study revealed that smoking and opium are risk factors of bladder cancer. Thus, appropriate training and intervention program need to be taken into account in order to prevent the cancer.

ABSTRACT
Introduction: Animal bites are one of the serious threats to human health, leading numerous consequences such as fatal disease of rabies. Given the importance of animal bite throughout the country, the purpose of the present study was to investigate the geographical distribution, time trend and epidemiological characteristics of animal-bite cases in Bardsir County, Iran.
Methods: This cross-sectional study was conducted on the records of people suffering from animal bite between April 2010 and March 2014 in Bardsir County. Data were analyzed in SPSS v.20 software using descriptive statistics including frequency and percentage, log-linear model and time series model. Arc GIS software was employed to plot the geographical distribution of animal-bite cases.
Results: The findings of this study indicated that totally 1,500 cases of animal bite had occurred during the study period. Mashiz district (with 695 cases of bite) had the most animal bites. In terms of time, animal-bite cases had no particular trend. The results showed that the incidence rate of bite in men was 2.12 times more than in women (p<0.001). In the age group of 31- 45 years compared to the reference age group (0-6 years), the rate of bite was 5.98 times greater (p<0.001). In the homemakers compared to the reference group (children) the incidence rate of animal bite was 4.96 times greater (p<0.001). Among the biting animals, dogs were responsible for the most bites (76.9%). In terms of bitten organs, limbs were bitten frequently (52.8%). The majority of victims had received the vaccine in accordance with the three-dose immunization schedule (91%).
Conclusion: It seems that the determinants regarding high incidence of animal bite in Bardsir County are the type of activities and occupations. Therefore, special and preventive educational programs might be useful in high-risk groups.

Introduction: Healthy and nutritional habits are formed and consolidated during adolescence. So this research has been done in Ardakan-Yazd province on high school students' attitude to fast food use.
Methods: In this cross-sectional descriptive study, 200 students have been chosen by stratified sampling method and the data was collected by a questionnaire which approved its reliability and validity. All the descriptive data has been analyzed by SPSS 16 software through Chi-square experiment and ANOVA tests. 
Results: The results of the experiment determined that 55% of the students were female, and 93% were single. The students' BMI was as follow: 22% thin (BMI< 18.5) 56% normal (18.5≤ BMI< 25) 14.5% overweight (25≤ BMI< 30) 6.5% fat (obese) (BMI ≥30).The female has a positive attitude to fast foods (P= 0.03). The mean attitude score for eating fast food in 17-18 years old group was more than 15-16 years old students (P= 0.001). The mean attitude score also showed that the single students were more eager to eat fast foods than the married students (P= 0.001)
Conclusion: Most of the people who use fast foods are low educated, teenagers, youth and singles. On the other hand, social media like TV and radio and family has a significant effect on correct nutritional habits. So improving family's attitudes and educating students and teachers by social media can help in transferring data to the students and their teachers.

Introduction: Pregnancy, especially the first pregnancy and childbirth, affects the women’s quality of life. Improving information-seeking behavior facilitates the decision-making process of women during pregnancy and postpartum. The aim of this study was to investigate the health information-seeking behavior of Iranian first-time mothers and first-time pregnant women.

Methods: This research was a cross-sectional-descriptive survey .A self-administered questionnaire was distributed among 358 first-time mothers and first-time pregnant women who attended 9 health centers in the northwest of Tehran, Iran, in 2017. Data were analyzed using SPSS version 24 and by conducting descriptive statistics and Kruskal-Wallis and Mann-Whitney U tests at .05 significance level.

Result: The most important information need of the first- time mothers and first-time pregnant women was "Fetal/newborn health"; the most important source of information used was "gynecologist"; the most important way to access the resources was "visiting a doctor in person," and the most critical barrier to access information was "high costs of visiting a doctor, midwife, or nurse." Testing the hypotheses showed significant differences between information seeking components and demographic characteristics of the respondents. It was also found that there was no significant difference between the components of information-seeking behavior among two groups of first-time mothers and first-time pregnant women (p>0.05).

Conclusion:  Making pregnancy-related health information more available and accessible and providing high-quality educational programs at affordable cost in health centers for first-time mothers and first-time pregnant women can help them increase their health literacy and prevent many common complications associated with pregnancy and child health.

Abstract
Introduction: Theory of planned behavior can provide a framework for intervention to understand how to prevent health problems. The aim of this study was to determine the effect of training intervention based on the theory of planned behavior in promoting oral health behavior of pregnant women who visit health care centers of Rafsanjan.
Methods: In this educational intervention trial, 100 pregnant women in Rafsanjan were selected by multi-stage sampling in 2016. Initially, four centers were randomly selected, followed by two centers selected as intervention groups and two centers as control groups. Data were collected using a three-part researcher-made questionnaire, that were completed by pregnant women in two periods, ie, before and three months after the intervention. Quantitative data were presented as mean ± SD and qualitative data as n (%). First, the homogeneity of the two groups was examined using an independent t-test and chi-square test. Data were analyzed with SPSS 18. The significance level of all tests was considered to be 0.05.
Results: Findings showed that there was no statistically significant difference between the demographics of the two groups (p> 0.05). After the implementation of the program, the mean score of intervention in all constructs of the theory of planned behavior model was significant between the control and intervention groups (p < 0.001). Following the educational program, the oral health behavior of pregnant women increased in the intervention group (3.72 ± 4.22) which was significantly higher than the control group (1.48 ± 2.58) (p < 0.001).
Conclusion: The results of this study showed that educational interventions can focus on the subjective norm which had fruitful results in the field of oral health. This theory can be used as an appropriate model for oral health promotion programs.
