Sleep is an essential component of mental and physical development in children and adolescents (1-4). However, insufficient sleep and disturbed sleep patterns are common in the pediatric age, with a rising prevalence throughout adolescence (2,5-7). Adolescence is considered a period with considerable alterations in sleep pattern in terms of amount and quality (7-10) in relation to physiological, environmental, social and behavioral changes specific to this life period (10-12). The trend of insufficient and deteriorating sleep and poor sleep hygiene among adolescents is considered a public health concern given the short and long term detrimental health outcomes including poor diet; sedative behavior; obesity; reduced immunity; stunted growth; cognitive impairment, poor academic performance and mental health problems

Maternal anemia has been reported as the most common hematologic problem in pregnant women. This disorder occurs frequently as a result of insuffucient intake of iron and folic acid during pregnancy (1-4). It is reported that iron deficiency anemia occurs in 85-100% pregnant women with insufficient supplementation of iron during pregnancy (5,6). The rate and severity of maternal anemia has some variabilities in the different geographic and economical distribution (5). While many women in developed countries start pregnancy with low iron stores, this is much more serious in developing countries. Maternal anemia in the gestational period may also be related to obstetric complications such as postpartum hemorrhage, operative delivery and placental abnormalities (5,6).
