[Association between hypertension and dietary patterns among adults residents of Khorramabad]

Hypertension is a common public health problem, both in the developed and the developing countries. In Iran approximately one in every four adults has high blood pressure. Many factors, e.g dietary pattern, can affect the incidence of high blood pressure. The aim of this study is to determine the relationship between hypertension and dietary patterns. In this cross-sectional study, the 973 participants were residents of Khorramabad. Food intake assessments were measured by a validated semi quantitative 201-item food frequency questionnaire [FFQ]. Hypertension was identified as systolic blood pressure>140 mm/Hg and/or diastolic blood pressure>90 mm/Hg. Dietary patterns were identified by factor analyses. Multivariate logistic regression was used to determine the associations of dietary patterns and hypertension. The three major dietary patterns identified were the Traditional Dietary pattern [TDP], the Healthy Dietary Pattern [HDP], and the Western Dietary Pattern [WDP]. Subjects in the highest quintile of the WDP scores had a greater odds ratio for hypertension [odds ratio: 2; 95% CI: 1.04-3.85; P=0.037] than those in the lowest quintile. Before BMI adjustment, compared with those in the lowest quintile, subjects in the highest quintile of HDP scores had lower odds for hypertension [0.56; 0.34-0.93; P=0.043], a relationship however that was not significant after BMI adjustment [P=0.06]. TDP consumption and hypertension were not significantly associated [0.71; 0.37-1.35; P=0.29]. The WDP had a direct association with the risk of hypertension. More longitudinal studies are needed to clarify the exact association between dietary patterns and hypertension

[Effect of iron supplementation prophylactic on maternal iron status and pregnancy outcome]

Background and aims: Considering the iron supplementation during pregnancy and the problems due to over using of this supplementation, almost all women take iron supplementation during pregnancy. The aim of this study was to determine the effect of the iron supplementation prophylactic on outcome and the problems of pregnancies

Methods: In this double- blind randomized clinical trial study 129 women with Hb > 110 g/l, serum ferritin > 20 micro g/l and gestational age less than 20 weeks were randomly divided to receive either of ferrous sulfate tablets [n=62], 1 table / day [60 mg] or placebo [n=67]. Hemoglobin and ferritin were also measured in the 24-28[th] weeks and at the end of pregnancy. In addition, weight and length were recorded at the beginning and during the pregnancy in both groups. Data were analyzed using independent-t test, ANOVA, and Chi square tests

Results: Iron deficiency prevalence in Fe and placebo groups was found 5.8 and 24.8 percent in the 24-28[th] weeks [P=0.002] and 9.5 and 28.2 percent at the end of the study respectively. No significant differences were found in hemoglobin and ferritin indices during the study in both groups. Average birth weight was 3.30+/-0.49 Kg and 3.27+/-0.47 Kg in Fe and placebo groups, respectively. Average length birth was 49.1+/-3.9 cm in Fe group versus 49.3+/-4.4 cm in placebo group. Duration of gestation in Fe and placebo groups were 38.9+/-1.7 weeks and 38.8+/-2.2 weeks, respectively [P>0.05]

Conclusion: The results of this study showed that iron supplementation during pregnancy may have no effect on pregnancy outcome. It is obvious that because of more iron deficiency prevalence in placebo group, absolute conclusion about whether iron supplementation prophylactic during pregnancy is useful or not, more studies are needed in the future
