Abstract
Background & Objectives: Malnutrition is widely regarded as one of the factors affecting quality of life. The adverse effects of malnutrition have been documented in various age groups. School problems, learning difficulties, humiliation and teasing from peers are some of the most common complications of obesity and excessive thinness. The goal of this study was to determine the BMI and some of the factors affecting it in the students of Dezfool.
Methods: In a cross-sectional study and using random cluster sampling, 5726 students from 39 clusters were selected and anthropometric measurements were performed in the schools and under standard conditions. Cases of obesity and thinness were identified using BMI percentiles for age and sex (NCHS). A Body Mass Index above the 95th and below the 5th percentile was defined as obesity and thinness respectively.
Results: This study involved the participation of 5508 students (96.2%). The prevalence of thinness was 33% (1716) with a 95% confidence interval of 27.3%-38.8%. The prevalence of obesity was 2.6% (157) with a 95% confidence interval of 1.7%-3.4%. There was no significant difference between the prevalence of obesity or thinness between the two sexes (P>0.05). The prevalence of obesity and thinness significantly increased and decreased respectively with aging (P<0.05).
Conclusions: Malnutrition among the students in Dezfool predominantly takes the form of thinness, while obesity is not a serious problem in this population overall, these findings indicate poor nutritional status. High-risk groups have been identified and they must become the target of interventions by the Health and Education Ministries.

Abstract
Background & Objectives: Macrosomia is a term applied to newborns with a birth weight more than of 4000 gr which cause different maternal and neonatal complications. Several risk factors has been known for macrosomia. The purpose of this cross-sectional study was to estimate the frequency and evaluate of risk factors of macrosomia in Asalian hospital of Khorramabad in 2010.
Methods: This study was undertaken in Khorramabad, Iran. The data collection instrument was a questionnaire containing 10 variables as the risk factors of macrosomia. The data were analyzed using the SPSS software.
Results: 59 cases of macrosomia were found in 500 living births, and the frequency of macrosomia was 11.8%. Also, 69.5% of the neonates were male and 30.5% were female. Maternal risk factors were mother's age at pregnancy, mother's obesity (BMI>=30), weight gain more than 18 kg during pregnancy, history of diabetes mellitus, history of macrosomia, prolonged gestational age, and multiparity (parity>=5). There was no significant relationship between mother's job and macrosomia.
Conclusion: The prevalence of macrosomia in Khorramabad was high (11.8%). Preventing pregnancy in mothers over 35 years of age by contraception ways, preventing maternal obesity before pregnancy, and control of blood glucose during pregnancy by suitable diet and insulin therapy are recommended to prevent macrosomia.

Abstract
Background and Objectives: Shift work could threaten health in the long term. The present research aimed to assess the association between shift work and body mass index (BMI) using the multilevel (hierarchical) model during a particular period of time.
Methods: The data of this longitudinal study were collected from a sample of Esfahan’s Mobarakeh steel and Polyacryl companies personnel during 2008 to 2011. Shift work schedule included day work and rotational shift work. The multilevel regression model was utilized for analysing the data and assessing the effect of shift work on BMI by controlling confounding variables including marital status, work expectation, age, company, and educational level.
Results: In this study, of 1368 workers, 42.3% (n=578) and 57.7% (n=790) were day workers and rotating shift workers, respectively. The mean (±SD) age of the day workers and rotating shift workers was 33.07 (±8.66) years and 33.31 (±8.70) years, respectively. After adjusting for confounding variables in a two-level hierarchical model, the association between shift work and BMI was not statistically significant (P=0.837). About 90% of total variation was related to personnel.
Conclusion: According to the results of the present study, no statistically significant relationship was found between shift work schedule and BMI. Thus, other similar studies with a longer follow up period (more than four years) and controlling more confounder factors are necessary to evaluate the relationship between shift work and BMI more accurately.

Abstract
Background and Objectives: Rheumatoid arthritis is a chronic, progressive disease of the joints that presents with articular and systemic symptoms. The purpose of this study was to determine the quality of life in patients with rheumatoid arthritis and its relationship with body mass index.
Methods: This descriptive-analytical study was performed in 195 patients with rheumatoid arthritis in Tohid Hospital, Sanandaj, Iran. The data collection tool was a questionnaire including demographic and clinical characteristics. The SF-36 instrument was used to evaluate the quality of life.
Results: In the study, 40% of men and 58% of women had a disease severity higher than 2.6 according to the Disease Activity Score 28. There was a significant difference in all dimensions of quality of life including physical function, energy / fatigue and general health between men and women (P <0.05). All dimensions of quality of life were inversely correlated with BMI. There was a significant relationship between the disease severity and each of the dimensions of pain, general health and general changes (P <0.05).
Conclusion: Quality of life in patients with rheumatoid arthritis is correlated with body mass index and severity of rheumatoid arthritis; therefore, it seems that health policy makers or clinical practitioners need to pay more attention to these two factors to increase the patients’ quality of life.

Abstract
Background and Objectives: Physical activity is one of the most important components of life. The aim of this study was to evaluate the physical activity level of primary school students in Bushehr in 1398.
Methods: In this cross-sectional descriptive-analytical study, the research population included all elementary school students in Bushehr. Four hundred and six students were selected using multi-stage random sampling. The Physical Activity Questionnaire for Children, which is a valid and reliable scale, was used to collect the data. Independent t test, one-way analysis of variance, Pearson correlation coefficient and multiple linear regression model were used for data analysis. Data was analyzed using the SPSS software version 20.
Results: The mean score of physical activity was 3.27±0.84. There was a significant relationship between demographic factors (parents’ education level, participant’s education level and BMI) and physical activity. Students whose parents had higher levels of education were more likely to engage in physical activity and people who were obese had less physical activity.
Conclusion: The students' physical activity was moderate. Given that there is a direct link between physical inactivity and increased prevalence of overweight and obesity, it is important to pay attention to the lifestyle of people, especially children and adolescents who are in the learning age. Therefore, more attention should be paid to improving the level of physical activity in students through education and building a culture.
