As adoptin and maintenance of healthy eating behaviours is an important factor for Ischemic Heart Disease (IHD) prevention , this research was conducted to determin dietetic risk factors in relation to IHD. This is a case – control study conducted in fall 2003 in Tehran Heart Center and Tehran Shahid Rajaii hospital. 100 subjects with IHD, as cases and 100 controls with no cardiovascular disease in their medical history, participated in the study.Nutritional data was collected by Food Frequencey Quastionnaire. Some important risk factors including hypertention, hyperlipidemia,diabetes, Body Mass Index (BMI) and physical activity were evaluated. There was a positive association between IHD and consumption of fats and a negative association between IHD and consumption of fruits and vegetables.The most important factors were low intake of fish and high intake of fried foods that increased the risk of disease 13.96 and 54.65 times, respectively. Also 73% of patients had high risk diet while only 17% of controls had high risk diet. High risk diet increased the risk of cardiovascular diseases approximately 20 times. The main dietetic risk factors in this study were : low intake of fish, fruits and vegetables and lower consumption of oiles while hydrogenated fats with undesirable trans-fatty acid content, were the main source of dietary fat, in case group. Therefore community-based educational programmes are nesseary to promote healty nutrition.

Background and Aim: Unwanted pregnancy is a widespread problem globally and in Iran, which can lead to low birth weight (LBW)-one of the most important causes of mortality in newborns. This study was conducted to assess the risk factors among women with unwanted pregnancies leading to delivery of LBW infants. Other LBW risk factors were also studied.

Methods and Materials: This was a prospective cohort study performed during March 2004 to April 2005 in the health centers of Shemiran, north of Tehran, Iran. A sample of 180 mothers, 15-49 years old, with an unwanted pregnancy (case group) and 430 mothers, in the same age group, with a wanted pregnancy (control group) were compared. To determine the effect of unwanted pregnancy three major type of variables (background, maternal, and neonatal variables) were selected, and the mothers were followed up for 11-12 months (from the first referral for prenatal care to about 2 months after delivery). Statistical univariate analyses were performed using the t- and χ2 tests. Also, multiple logistic regression was employed to identify the risk factors associated with LBW. SPSS 11.5 for windows was used for data analysis.

Results: The unwanted pregnancy prevalence was 11.7%. The mean of Apgar score was 8.6 in the case group and 8.9 in the control group, the difference being statistically significant (p<0.001).Mean birth `1234t5weight of neonate in the case group was about 2.984kg vs. 3.14kg in the control group, and the difference was statistically significant (p<0.001) . Univariate analysis showed that LBW was related to unwanted pregnancy (p<0.001), gestational age (p<0.001), mother's age (p<0.001), mother's marriage age (p<0.001), birth order (p<0.001), number of past pregnancies (p<0.001), family size (p<0.001), number of abortions (p<0.001), attempt to abort (p<0.001), high blood pressure (p<0.001), and diabetes (p<0.001). Finally, multivariable analysis revealed that LBW was only associated with unwanted pregnancy, high blood pressure, and diabetes in mothers, with adjusted odd ratios of 2.22, 2.81 and 3.55, respectively (p<0.05).

Conclusion: Prevention of unwanted pregnancies, increased gestational age, and appropriate management of mothers' chronic diseases can reduce the risk of LBW.
