Background and Aim: The prevalence of congenital hypothyroidism (CH), one of the main causes of preventable mental handicap in neonates, is much higher in Iran than the global average.
The objective of this study was to identify risk factors for congenital hypothyroidism (CH) by using the screening program in Fars Province, Iran, during the period 2003-2006.

Methods and Materials: A case-control study was carried out, the samples being 126 cases and 401 controls. The neonates were those born between 2003 and 2006, under coverage of the National Congenital Hypothyroidism Program. The data were analyzed using the univariate and multivariate analysis tests.

Results: An increased risk for CH was detected in infants with consanguine parents, by a multivariate analysis test (odds ratio (OR) = 2.9, 95% confidence interval (CI):1.8-4.8). The test also confirmed previously reported statistically significant associations with additional birth defects OR = 2.2 (1-4.6), birth defects in first-degree relatives OR = 4.7 (1.6-4.8), female gender OR = 1.9 (1.1-3), and twin births. Although not significant, an increased risk for CH was observed among infants with gestational age<30 weeks (preterm delivery) (OR = 1.7(0.9-1.3)).

Conclusion: This study identified risk factors contributing to the etiology of CH. In particular, our results suggest a multifactorial origin of CH, in which both genetic and environmental factors play a role.

  Background and Aim: Malaria remains an important vector-borne disease globally and is a threat for human life. Forty percent of the world’s populations who are living in low-income countries are at risk of malaria. The disease exists in Iran and caused economic and social damages. As result of malaria control program that has been done during the past years, the disease is eliminated from the most parts of the country, so that it is only reporting from a small part in these years.

  Materials and Methods : During this study, all available papers, books and thesises were reviewed and articles from Iranmedex, DIS and PubMed databanks were also used. Furthermore the related reports from different sources were noted.

  The extensive studies have important information about malaria vectors. In this study the data about malaria vectors and related training courses are listed. During this study the related papers, Books and thesises which have been reviewed.

  Although efforts, surveillance system, diagnostic and treatment facilities, as well as knowledge and attitude of peoples regarding to health behavior are improved nowadays, there are significant improvements about decreasing the malaria cases. Risk of the disease exists because of population exchange and asymptomatic cases. The malaria can be studied with both public health and economical aspects. This paper represents entomological studies of malaria during 1935 by the end of 2008.

  Conclusion: our study revealed that, based on recent malaria national program, the authorities should make an emphasis on vector control monitoring, resistance management, malaria evaluation and because of weak supervision on all malaria operation at stage of elimination of malaria, accurate and careful suppersional require to reach the objective and goal of elimination.

  Background and Aim: High fruit and vegetable intake has been introduced as one of the key factors of healthy diet to prevent chronic disease. This study attempts to explore the fruit and vegetable intake in Arak city and its relationship with demography and socio-economic factors.

  Materials and Methods : In this cross sectional study, 660 people in 18 -70 age range were selected with a two-stage cluster sampling and were interviewed for demography and socio – economic questionnaires and a 56- items semi-quantitative food frequency questionnaire to assess fruit and vegetable intake. After univariate analysis, the association of the significant variables with fruit and vegetable intake was also evaluated with multiple linear regression.

  Results: In this study, over 60 percent of subjects consumed less than the minimum recommended amount of fruit and vegetable (5 servings or 400 gr a day).The total consumption of fruit and vegetable indicated an inverse significant relationship with age (p =0.04 and β = - 0.02), and a direct significant relationship with economic status (p <0.001and β =0.10). The father's educational level (p =0.005 and β =0.38 for diploma level and p =0.03 and β =0.36 for academic education) and physical activity level (p =0.001 and β =0.03 per hour) were factors associated with fruit consumption. The gender was only associated with vegetable consumption so that women had higher consumption in this study (p =0.03 and β=0.23).

  Conclusion: The findings of this study indicate low fruit and vegetable consumption in the population under study. In this study, age, physical activity, and socioeconomic status and fathers’ education were the factors that were significantly associated with fruit and vegetable consumption.
