ABSTRACT
BACKGROUND: Case finding was improved to the population-based method at the Isfahan Cancer Registry (ICR) during 2005-2008. However, its effects on the number of registered colorectal cancer (CRC) cases and patients' age are not investigated. Therefore, present study designed to investigate the effect of that improvement on the trend of incidence of CRC, and age of CRC cases in ICR's catchment area. METHODS: Data from the ICR were retrieved by years for 2000-2011. Annual age-standardized incidence rates (ASRs), truncated ASRs and 95% confidence intervals (95% CIs) were estimated for both genders. Rates were standardized based on the 2000 world standard population. Trends were analyzed, and significant change-points were identified using Joinpoint Regression software. Age of CRC cases compared between periods before and after the improvement. RESULTS: A total of 2902 CRC cases had been registered by ICR. Estimated ASRs (95% CI) for 2000 and 2011 were 3.47 (3.45, 3.50) and 10.22 (10.19, 1025) per 100,000 persons, respectively. Two significant change-points were identified (i.e., at 2003 and 2006). However, estimated average annual percent change was as 11. There was no significant difference between mean of patients' age before and after the time of improvement (P = 0.88). CONCLUSIONS: Trends of incidence of CRC had been rising in central Iran for males and females, during 2000-2011. It seems that the estimated slope for this trend had been partially artificial and significantly affected by the improvement of case-finding method. However, the improvement had no effect on the patients' age.
ABSTRACT
BACKGROUND: To facilitate analysis, interpreting and sharing cancer data and investigation spatial and geographical aspect of cancers in Isfahan province, cancer cases distribution was displayed using geographic information systems (GIS). METHODS: About 118,000 cancer data, which were confirmed in national cancer registration unit were extracted. Age-specific incidence rate and age standardized rate (ASR) of cancer cases from 2006 to 2010 was calculated for Isfahan province and its different districts. Distribution of ASR was determined according to sex and age groups. Spatial maps were drawn with the help of Arc GIS version 10 (ESRI, Redland, CA, USA) software in choropleth based maps. The data are classified in GIS environment by means of quantile method. Data were described with the help of maps spatially. RESULTS: Age standardized rate of cancers was higher in men than in women (134.58 vs. 115.4). The highest ASR was reported in the Isfahan (ASR: 133) and lowest in the Chadegan counties (ASR: 28). Different geographical distribution patterns of cancers were seen in district level. Cancer incidence was higher in the Isfahan, Lenjan, Fereidon Shahr and Falavarjan districts (134.3, 117.2, 113.5 and 111.1 respectively) among men and in Isfahan, Shahin Shahr, Lenjan and Najafabad districts (122.8, 102.3, 94 and 93 respectively) among women. The incidence rates of most cancers were lowest in the North East region of the province compared to the rest of the region. CONCLUSIONS: Using GIS for visual displaying of cancers facilitated communication with the policymakers and community. This study provided hypotheses about differences in the incidence of cancer in Isfahan districts. Higher age-specific incidence rate in the Isfahan city is probably a reflection of problems in addressing the patients in cancer registration. Complementary studies are needed to evaluate lower ASR in the North East regions of the province.
ABSTRACT
BACKGROUND: Adolescents are being threatened by several accidents because of entering the new world of adulthood, separation from families, a greater presence in community individually, the lack of knowledge of rules and risk-taking spirit of adolescents, and events. The contribution of these damages and their related costs are higher in developing and low-income countries. The current study was conducted for proper planning focused on reducing accidents that have the highest incidence, evaluating school events, determining the place and time that most accidents happened to students and determining the body part injured. METHODS: A cross-sectional study using a multistage cluster sampling was conducted on 6933 students 11-14 years old (middle school) in 2009-2010 in Isfahan Province. The data were collected through observation and a researcher-made questionnaire and then entered into the EPi6 software, and analyzed by the SPSS 11.5 software and the statistical test of Chi-square. RESULTS: The findings showed that 49.9% of students were girls (n = 3462) and 50.1% (n = 3471) were boys, 84.5% of students (n = 5860) were living in urban areas and 15.5% of students (n = 1073) were living in rural areas. Frequency distribution of incidents was 53.9% (3739 cases) at school and 10.6% (732 cases) on the commuting route. The most injured body part was hand with 1018 cases (18.5%) and foot with 1267 cases (23.1%), and mostly they were injured in boys. CONCLUSIONS: The findings showed that a high percentage of students were injured at school, where the first step to prevent the incidence of such preventable incidents at school is to secure workshop environments and school yards.
ABSTRACT
BACKGROUND: Population growth and use of the car in daily life entails new incidents and accidents everyday. Adolescents' entering the new world of adults, their insufficient knowledge of rules, and high-risk behaviors expose them to more risks. Accordingly, a study was conducted with the aim to evaluate the status of preventive behaviors in traffic accidents in boy and girl junior high school students in Isfahan regarding vehicle use. METHODS: A descriptive-analytical cross-sectional study was conducted on 7000 junior high school boy and girl students from 20 towns in Isfahan Province using multi-stage cluster sampling method in 2009-2010. A researcher-made questionnaire was used as data collection tool, which evaluated students' practice and preventive behaviors with 21 questions, each examining students' practice in accidents and incidents that may occur in school and on the way to school. Data were analyzed with Epi 6 and SPSS software using t-test and Chi-square test. RESULTS: Girls comprised 49.9% of students and 50.1% were boys, 84% lived in urban areas and 15.5% in rural areas. The frequency of an accident location was school in 53.9% with 3739 cases and on the way to school in 10.6% with 732 cases. Mean practice score of preventive behaviors in traffic accidents involving cars, taxi, and school bus (72.6 ± 17.52 girls, 72.7 ± 18.31 boys, P = 0.88), motorbike (79.1 ± 14.048 girls, 74.1 ± 19.73 boys, P < 0.001), bicycle (71.4 ± 16.56 girls, 68.5 ± 14.69 boys, P = 0.152), bus and minibus (91.8 ± 13.16 girls, 87 ± 18.65 boys, P < 0.001), crossing the street (30.5 ± 26.67 girls, 32.7 ± 28.03 boys, P = 0.003), and skating (60.6 ± 29.103 girls, 61.2 ± 26.84 boys, P = 0.927). Results indicate that girls have better preventive practices than boys in use of motorbikes, buses, and minibuses. CONCLUSIONS: According to the results obtained, the majority of students walk to school and have the lowest practice score in this respect. It is recommended that as the first step, students be given necessary road traffic rules training, particularly how to cross the street.
ABSTRACT
BACKGROUND: The tragedy of having breast cancer can cause many challenges for women. Patients seek for someone to compare their emotional and physical reactions with. This study was conducted to evaluate the impact of implementation of peer support group on the quality of life of breast cancer patients. MATERIALS AND METHODS: This clinical trial was conducted on patients who underwent modified radical mastectomy and/or lumpectomy in surgical wards of Isfahan and Tehran (2 cities in Iran). The members of the peer group were trained after they volunteered to enter the study and their capacity was evaluated. They started contacting the patients after the surgery and continued it during treatments and several months after completion of the treatments. Patients were placed in 2 groups of case and control by simple random sampling. The quality of life of patients in both groups was measured during and after the completion of treatment using standard instruments of National Medical Center and Beckman Research Institute. FINDINGS: The mean score of the physical dimension of life quality in the case and control groups in Tehran had a significant difference during 2 stages. There was no significant difference between the mean scores of physical dimension of life quality between the 2 groups during the 2 stages in Isfahan. Moreover, the mean scores of mental dimension of the quality of life showed a significant difference between the 2 groups in Tehran during the 2 stages. The mean scores were also significantly different during the second stage in Isfahan. There was a significant difference between the social dimension of quality of life between the 2 groups in Isfahan (p = 0.001). The mean scores of the social dimension of quality of life had significant differences between the 2 groups in Tehran during the 2 stages (p < 0.001). There was a significant difference between the 2 groups regarding the mean score of spiritual dimension of quality of life in Tehran (p < 0.001). CONCLUSIONS: The results showed that patients supported by a peer group enjoyed a higher quality of life compared to others. Although significant differences were observed in scores of both case and control groups in Tehran, similar findings were not obtained in Isfahan. This may be due to incomplete matching of the peer group members and incapability of the volunteers to maintain an effective and constructive communication with the patients.
ABSTRACT
BACKGROUND: Cancer incidence rate is increasing in the world particularly in developing countries. The awareness regarding cancer incidence and distribution helps policy makers and researchers to design comprehensive plan for controlling cancer. The aim of this study was to determine the incidence rate and trend of cancer in Isfahan area, one of the most importance provinces of Iran. METHODS: Data of Isfahan cancer registry were derived from 2005 to 2010. Direct standardization through world standard population produced by the world health organization was used and adjusted standard rate (ASR) was calculated. The Poisson regression analysis was employed to estimate cancer incidence trend during 5 years. RESULTS: The new cases of cancer were 24771 patients from 2005 to 2010. Mean age of these patients was 56.1 ± 18.0 years and 54.6% were male. Male patients were approximately 7 years older than females. The most frequent cancer was gastrointestinal in men and breast cancer in women. The rate of cancer increased approximately 4 per 1000 population and incidence rate ratio (IRR) was 1.004 (95%CI: 1.002-1.005). CONCLUSIONS: The rate of cancer is increasing rapidly in Isfahan province. Cancer control and comprehensive prevention plan for Isfahan is necessary.
