Context. Avoidance of the prone sleeping position is considered an important factor contributing to the decline in the incidence of sudden infant death syndrome (SIDS).Objectives. To determine infant sleep positioning practices and SIDS awareness before and after a hospital-based Back to Sleep campaign.
Design.A questionnaire-based, descriptive, and cross-sectional before-after trial.Setting. The pediatric outpatient department of an inner-city hospital in Brooklyn, New
York.Subjects. Two consecutive samples of 250 mothers of healthy infants younger than 6 months old born in and attending the outpatient clinics of the hospital before and after the intervention.Intervention and Main Outcome Measures. Specific policies promoting Back to Sleep were established in our newborn nursery and outpatient department. Reduction in prone infant sleep positioning was the primary outcome measure. Increased parental SIDS awareness was a secondary outcome.Results. The proportion of infants sleeping prone was reduced significantly (from 27% to 18%) after the intervention (P < .005). Among the mothers who chose the prone sleeping position for their infants, 49.6% worried about choking. Older mothers (>22 years) responded to the intervention by a 45.6% reduction in prone placement (P < .005) as opposed to a 11.4% reduction among younger mothers (<22 years) (P = ns). Other factors contributing to reduced prone positioning included marriage (adjusted odds ratio [OR] 0.57; 95% confidence interval [CI] 0.93, 0.34) and breast feeding (adjusted OR 0.66; 95% CI 1.1, 0.4). SIDS awareness was 79.6% and 82.4% in the preintervention and postintervention groups, respectively (P = ns).
Iron deficiency anemia (IDA) continues to be overwhelmingly the leading cause of anemia in early childhood and a global public health challenge. Although there has been a significant decrease in the frequency of IDA and iron deficiency (ID) in infants and toddlers in recent years in the United States, ID and IDA persist and the adverse effects of ID are long-lasting if not permanent. Moreover, ID can result in lead toxicity, and this toxic exposure, even with low levels, can impair neurocognitive function as well. This review describes the major steps that have taken place to decrease the frequency of ID and IDA.
Iron deficiency in toddlers is associated with impaired cognition and is an underestimated and undertreated problem. The prevalence of iron deficiency anemia (IDA) during the first year of life has been dramatically reduced in developed countries, mainly due to the increase in breastfeeding and the use of iron-fortified feeding formulae. However, in US and UK children aged 1-2 years, recent studies have shown prevalence rates of >10% and 30% for IDA and iron deficiency, respectively. The daily iron intake in children aged 1-2 years is lower than in any other age group during life. IDA during the first 2 years of life is associated with impaired mental and psychomotor development and these deficits are long lasting, and perhaps irreversible, despite the correction of the anemia. Another compelling reason to prevent iron deficiency in children, especially in children aged 1-2 years, is the proven association of iron deficiency with increased lead absorption. Lead-associated cognitive deficits occur at blood lead levels <10 microg/L, a level once thought to be harmless. The current prevalence rates of iron deficiency and IDA in toddlers, especially among those in the lower socioeconomic groups, are unacceptably high. These young children are doubly at risk for neurodevelopmental impairment, both from the iron deficiency itself as well as from CNS damage caused by the associated increased lead absorption. The current screening and treatment recommendations for IDA in the US and in other developed countries appear to have been unsuccessful in preventing iron deficiency and IDA in a large number of toddlers. Similarly, the associated problem of impaired mental and psychomotor development has not been adequately recognized or addressed in the existing medical literature. The author recommends that, after breastfeeding or an iron-fortified formula is stopped, iron deficiency and IDA be prevented by routine daily supplemental doses of 10mg of elemental iron via iron-fortified vitamins, iron drops, or iron-fortified drinks.
