Nutrition knowledge, attitudes, and practice towards breast cancer prevention among the female population of Iran University of medical science students

Diet plays a measurable role in breast cancer (BC) prevention. The aims of this study were to assess nutrition-related BC prevention Knowledge, attitudes and practice (KAP) of female university students and to examine the relationship between demographic characteristics of students and their KAP. We conducted a cross-sectional study among 500 female students from Iran University of Medical Science (IUMS). A pretested self-administered questionnaires were used to assess the participants� nutrition-related BC prevention KAP. A total of 500 students completed the survey. Students� knowledge with the mean score of 16.97, significantly varied by age (P= 0.03), the field of study (P= 0.001) and family history of BC (P= 0.01). The mean score of attitudes and practice toward nutrition-related BC prevention factors were 24.86 and 39.39, respectively. A significant relationship was observed between nutrition knowledge and attitude (r = 0.27, P < 0.001). Also, Nutrition-related attitudes were positively correlated with the BC prevention dietary practices (r = 0.23, P < 0.001). Nutrition KAP about BC prevention factors was found to be influenced by individual factors such as age, field of study, familial history of BC, job and residency status. Together, our findings confirm that increasing nutrition knowledge is not sufficient for dietary behavior change, but is necessary. © 2019, © 2019 Taylor & Francis Group, LLC

The Study of Total IgE Reference Range in Healthy Adults in Tehran, Iran

&quot;nBackground: IgE is an antibody class that regarded as an important factor in the pathogenesis of allergic diseases, asthma, im&amp;shy;mune responses to parasitic infection and it could be responsible for the late- phase allergic response. The objective of this study was to evaluate total IgE in healthy Iranian adults, establishment of reference range of total IgE and assess helpful&amp;shy;ness of this value in clinical diagnosis atopic and allergic diseases.&quot;nMethod: Three hundred sixty six healthy adults from blood transfusion volunteers (18 to 60 years) were selected in this study. A specific questionnaire (including demographic factors, smoking status and ...) was filled out for each person. Also, we evaluated effect of race and education on total IgE. These adults had no history of allergic disease. The total serum IgE level using a commercial enzyme immunoassay and CBC (Eosinophil count) was determined in them.&quot;nResults: Mean of age was 37.32&amp;plusmn; 10.93 yrs and 219 cases were males and 147 females. The geometric mean of total IgE was 20.84 IU/ml (2-373 IU/ml) (95% percentile= 250) (95% confidence interval=46.27-62.70). No differences was observed between mean of IgE log in males and females (P= NS) but mean of total IgE log in females is more than males.&quot;nConclusion: Normal range of serum total IgE obtained in this study could be helpful for diagnosis of IgE-dependent allergic dis&amp;shy;ease, as reference ranges in Iranian healthy adults
