Abstract
Background & Objectives: Iron is a major essential micronutrient during pregnancy and has an important role in intrauterine fetal growth and safe delivery. This survey was designed to study the status of anemia, iron deficiency and iron deficiency anemia in pregnant Iranian women. The results can help health policy-makers with the design and implementation of targeted strategies to overcome these problems.
Methods: This cross-sectional study involved 4368 women at gestational ages ranging from 6 to 9 months. Subjects were drawn through cluster sampling from 11 different regions of the country. Hemoglobin (Hb), hematocrit (Hct), mean corpuscular volume (MCV) and serum ferritin levels were measured and the prevalence of anemia, iron deficiency and iron deficiency anemia (IDA) was determined both nationwide and separately in each region.
Results: Overall, 21.5% of the women suffered from anemia 42.7% were iron deficient and the prevalence of IDA was found to be 10.4%. The prevalence of anemia s was significantly greater in rural areas than in urban settings (22.2- 27.8% compared to 17.1 -21.6%, 95%CI). The highest prevalence of anemia and low Hct was seen in the women of region 5 (including Sistan and Baluchistan, South Kerman and South Khorasan with rates of 44.2% and 40.5% respectively). Region 6 (covering Isfahan, Yazd, Kohkilooyeh-Boyerahmad and North Kerman) had the lowest prevalence of anemia and low Hct (9% and 10.8% respectively). Use of iron supplements (even irregular) had a positive effect in reducing anemia. It affected Hct levels only when taken regularly.
Conclusions: Anemia is still a major health issue for pregnant Iranian women. Although supplementation should be continued, there is a need for more comprehensive interventions addressing all target groups, especially women of child-bearing age.

Abstract
Background & Objectives: Recent evidence suggests that long-term exposure to air pollution contributes to progression of atherosclerosis and the risk of cardiac morbidity and mortality short-term exposure may also lead to thrombosis and acute ischemic events. To evaluate the relation between the levels of major air pollutants (CO and PM10) and hospital admission for acute coronary syndrome (ACS) in Tehran, we performed a case-crossover design and checked whether individual characteristics act as effect modifiers.
Methods: We selected 250 Tehran residents who had been hospitalized with an acute coronary syndrome from 4th of April to 10th of June, 2007. The following individual data were gathered: sex, age, date of hospitalization, and coexisting illnesses (hypertension, diabetes). Daily air pollution data were taken from the Air Quality Control Center. Temperature, humidity, stress, physical activity and weekend days were treated as confounding variables, and a conditional logistic regression model was used for statistical analysis.
Results: We found a positive association between ACS and average 24-hour CO levels. The OR for each unit increase of the average 24-hour CO was 1.18 (95%CI: 1.03-1.34). The relation between ACS and 24-hour average PM10 did not reach statistical significance (OR for average 24-hour PM10 was 1.005, 95%CI: 0.99-1.01). The association between ACS and 24-hour average CO tended to be stronger in women (OR=1.68 for each unit increase, 95%CI: 1.25-2.26). The relation between 24-hour average PM10 and ACS did not change across the layers of the effect modifiers.
Conclusions: The results suggest that an increase in average 24-hour CO levels will augment the risk of ACS, and the effect is stronger in females. On the other hand, we were unable to document an association between ACS and average 24-hour PM10 levels.
