Iron deficiency is known to be the most common nutritional disorder. About 30% of the world's population is iron deficient (ID). Women are more likely to be exposed to anemia than men, which is an epidemic public health problem. A cross-sectional study was carried out to investigate the prevalence of anemia and associated risk factors among non-pregnant women in Riyadh, Saudi Arabia. Non-pregnant women (n = 250) aged 20-65 years were involved in this study. Sociodemographic, nutritional status, menstrual history, anthropometric and haematological properties were calculated. Anaemia proxies including haemoglobin (HB), serum ferritin (IDA), Haematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were determined as well as BMI. The respondents were varied according to demographic factors and according to anemia proxies, the majority of them suffered from anemia. The Student's t-test analysis showed that the average daily food intake was lower than that of the dietary requirement intake (DRI). Correlation and logistic regression analysis between sociodemographic factors and anemia proxies revealed that most of such factors significantly and negatively affected anemia proxies. Moreover, the correlation of daily food intake and anemia proxies showed that the nutrients responsible for the improvement of anemia proxies were not taken in sufficient amount as indicated by a significant and positive correlation. In conclusion, various factors including demographic factors, daily food intake appeared to be associated with anemia proxies, which are the most important risk factor for anemia among non-pregnant women in Riyadh, Saudi Arabia.
