Background: Obesity in children has raised worries about public health and hygiene. In this study, we intended to evaluate the obesity rate among the children from first grade elementary schools throughout Sari, in the north of Iran. Moreover, we evaluated the possible effects of mother's life conditions on the estimation of obesity in children. Methods: In this descriptive cross sectional study, the study population included first grade elementary school students in Sari, north of Iran. Sampling was carried out through multi-stage and stratified randomization at level of the target students. Using stadiometer and digital scales, the height and weight were measured. Body Mass Index (BMI) was also calculated. A questionnaire about eating habits and socioeconomic status of parents was employed. Data collection was conducted using phone interview with parents as well as the questionnaire's records. Analysis of data was conducted in SPSS v.22 using suitable statistical tests. IBM SPSS Amos software was utilized for path analysis. P<0.05 was considered as statistically significant. Results: It was observed that 15% of the evaluated cases were obese. There was an association between BMI of the obese cases and lifestyle-related habits. Path analysis revealed significant impression of patient's habitus on the obesity of children. Conclusions: Our results suggest that the overall prevalence of obesity in Sari was high, which proposes the necessity for serious consideration in the health system, and designing, developing, and implementing preventive approaches with regard to childhood obesity.

Background and Purpose: Disasters and traffic accidents as the leading causes of disability and death throughout the world are the most significant health problems which have usually been predictable and, therefore, possible to prevent. The present study, as the first attempt, was conducted to calculate the burden of life years lost due to early death caused by traffic accidents in Mazandaran Province. Materials and Methods:The current study was cross-sectional, and the data was collected from the center of Mazandaran Legal Medicine. The number of years of life lost due to premature death was calculated by using the instructions GBD2010 age and gender composition of the province was taken in the last census in 2012 from the Statistical Center. Then the SPSS Software was used to key in all the collected information in order to perform the analysis. Results: Of the total population in 2015, 729 deaths were recorded due to car accidents with 77.9 percent of them being male. Mean age was 43.07±21.18 and 44.67±23.34 in women. The number of years of life lost due to premature death was 24972.7 years in men, 6965.3 years in women, and the total of two genders was 31938 years (10.6 years per thousand people) which were calculated, and it was the highest in the age group ranging from 20 to 24 years old. Discussion: According to the high rate of deaths from traffic accidents and damages resulted from it, and in order to reduce these losses, it is necessary to take appropriate preventive measures.

Background: Anxiety disorders are the most common groups of mental disorders. Based on the world health organization reports 7.4% of global DALYs are caused by disorders, which are in the mental and behavioral category. One of the problems of these patients is the length of stay in the hospital, which can be studied in various aspects. Objectives: The objective of this study was to determine the effects of related factors on the duration of hospitalization in patients with anxiety disorders. Methods: A historical cohort of patients placed in the psychiatric center in Sari, northern Iran, were studied from April 2007 to March 2012. Statistical analysis using Weibull regression and stata.12 was performed at the significant level of 0.05. Results: A total of 427 persons were studied. The median length of hospital stay was 17 (inter quartile range 10 -29 day). The results showed age was associated with the length of stay (P = 0.036). Also, patients with previous hospitalization and patients who received electro convulsive therapy and occupational therapy had a longer stay in the hospital (P < 0.001). Conclusions:The overall results showed that the type of treatment is effective in reducing the duration of hospitalization. Aging has a subtractive effect on the length of hospital stay. It seems that additional research concerning mental health care services may be required to identify more factors affecting the length of stay.

Background Today, with the progress of medical sciences, increasing the cure probability and survival time is an important goal of cancer treatment. This study compared long-term disease-free survival (DFS) of non-metastatic breast cancer patients based on different molecular subtypes. Methods This retrospective cohort study consisted of 1287 patients diagnosed with breast cancer and treated at Motamed Cancer Institute from 2000 to 2016 and followed up until 2018. Kaplan–Meier curve was fitted to data based on molecular subtypes. Then the semi-parametric mixture cure model was applied to determine the survival and cure probability of molecular subtypes by adjusting clinical and demographic factors. Results Among 1287 breast cancer patients, 200 (15.5%) cases died. The mean age of patients was 47.00 ± 10.72 years. Women with the HR+/HER2-subtype had the best 5-year survival rate (84.2%), whereas other subtypes had a lower rate as follows: HR+/HER2+ (77.3%), triple-negative (76.5%), and HR−/HER2+ (62.3%). Kaplan–Meier curve calculated a cure rate of about 60% and patients who survived more than 150 months were intuitively considered cured. After adjustment for clinical and demographic variables, the cure probability of HR−/Her2+ patients was substantially lower than HR+/HER2– patients (OR = 0.22), though there were no significant variations in short-term DFS based on molecular subtypes (HR = 0.91). Conclusions Our results confirm that the most prevalent breast cancer was HR+/HER2− tumor type which had the best prognosis. It is also concluded that HR−/HER2+ patients had the worst outcomes, with the highest rates of recurrence and metastasis and the lowest overall and disease-free survival rates.
