          Abstract

          Background

          Neonatal hypothermia is a worldwide problem and an important contributing factor for Neonatal morbidity and mortality especially in developing countries. High prevalence of hypothermia has been reported from countries with the highest burden of Neonatal mortality. So the aim of this study was to assess the prevalence of Neonatal hypothermia and associated factors among newborn admitted to Neonatal Intensive Care Unit of Public Hospitals in Addis Ababa.

          Methods

          An institutional based cross-sectional study was conducted from March 30 to April 30, 2016, in Public Hospitals in Addis Ababa and based on admission rate a total of 356 Neonates with their mother paired were enrolled for the study. Axillary temperate of the newborn was measured by a digital thermometer at the point of admission. Multivariate binary logistic regression, with 95% confidence interval and a p-value < 0.05 was used to identify variables which had a significant association.

          Results

          The prevalence of Neonatal hypothermia in the study area was 64% . Preterm delivery (AOR = 4.81, 95% CI: 2.67, 8.64), age of Neonate ≤24 h old (AOR = 2.26, 95% CI: 1.27, 4.03), no skin to skin contact with their mother immediately after delivery (AOR = 4.39, 95% CI: 2.38, 8.11), delayed initiation of breastfeeding (AOR = 3.72, 95% CI: 2.07, 6.65) and resuscitation at birth (AOR = 3.65, 95%CI: 1.52, 8.78) were significantly associated with hypothermia.

          Conclusions

          The prevalence of Neonatal hypothermia in the study area was high. Preterm delivery, age ≤ 24 h old, no skin to skin contact immediately after delivery, delayed initiation of breastfeeding and resuscitation at birth were independent predictors of Neonatal hypothermia. Therefore attention is needed for thermal care of preterm newborn and use of low-cost thermal protection principles of warm chain especially on early initiation of breastfeeding, skin to skin contact immediately after delivery and warm resuscitation.

          The global burden of neonatal hypothermia: systematic review of a major challenge for newborn survival

          Background To provide evidence on the global epidemiological situation of neonatal hypothermia and to provide recommendations for future policy and research directions. Methods Using PubMed as our principal electronic reference library, we searched studies for prevalence and risk factor data on neonatal hypothermia in resource-limited environments globally. Studies specifying study location, setting (hospital or community based), sample size, case definition of body temperature for hypothermia, temperature measurement method, and point estimates for hypothermia prevalence were eligible for inclusion. Results Hypothermia is common in infants born at hospitals (prevalence range, 32% to 85%) and homes (prevalence range, 11% to 92%), even in tropical environments. The lack of thermal protection is still an underappreciated major challenge for newborn survival in developing countries. Although hypothermia is rarely a direct cause of death, it contributes to a substantial proportion of neonatal mortality globally, mostly as a comorbidity of severe neonatal infections, preterm birth, and asphyxia. Thresholds for the definition of hypothermia vary, and data on its prevalence in neonates is scarce, particularly on a community level in Africa. Conclusions A standardized approach to the collection and analysis of hypothermia data in existing newborn programs and studies is needed to inform policy and program planners on optimal thermal protection interventions. Thermoprotective behavior changes such as skin-to-skin care or the use of appropriate devices have not yet been scaled up globally. The introduction of simple hypothermia prevention messages and interventions into evidence-based, cost-effective packages for maternal and newborn care has promising potential to decrease the heavy global burden of newborn deaths attributable to severe infections, prematurity, and asphyxia. Because preventing and treating newborn hypothermia in health institutions and communities is relatively easy, addressing this widespread challenge might play a substantial role in reaching Millennium Development Goal 4, a reduction of child mortality.

            Neonatal hypothermia in low resource settings: a review.

            Hypothermia is increasingly recognized as a major cause of neonatal morbidity and mortality in resource poor settings. High prevalence of hypothermia has been reported widely from warmer high mortality regions of Africa and South Asia. The World Health Organization recognizes newborn thermal care as a critical and essential component of essential newborn care; however, hypothermia continues to remain under-documented, under-recognized and under-managed. This review aims to provide a thorough patho-physio-epidemiological discussion of neonatal hypothermia applied to local risk factors within the developing country context with particular emphasis on prevention, recognition and management. All available published literature on neonatal hypothermia relevant to resource poor settings were reviewed. Studies from the developing country settings were primarily reviewed for epidemiology, domiciliary risk factors as well as potential interventions for thermal care. Functional integrity and efficiency of biological systems is critically dependent on an optimal and very narrow range of core body temperature. Risk factors for neonatal hypothermia differ markedly within low resource settings. A combination of physiological, behavioral and environmental factors universally put all newborns, irrespective of birth weight, at risk of hypothermia. The knowledge deficit along the continuum from health providers to primary care givers has sustained the silent epidemic of hypothermia. The challenges of recognition, understanding of local risk factors and communication have meant a lack of informed thermal care for newborns. Simple, feasible interventions exist, but need to be applied, based on local risk factors that disrupt the warm chain. Further research is needed to document local risk factors, develop better techniques for recognition, evaluation of thermal care within essential newborn care and communication strategies for program effectiveness.

              Hypothermia of newborns is associated with excess mortality in the first 2 months of life in Guinea-Bissau, West Africa.

              To examine the long-term effects of neonatal hypothermia (HT) on survival. Using the longitudinal community and hospital surveillance system of the Bandim Health Project, we followed children born between 1997 and 2002 at the only maternity ward in the city. All children's axillary temperature was measured within 12 h of birth. They were followed from birth to 6 months of life through regular home visits. We identified 2926 live births in the study area and 177 deaths before 6 months of age. Based on mortality risk, we defined a temperature below 34.5 degrees C as the cut-off point for HT. Two hundred and thirty-eight (8%) children had HT. Controlled for birth weight, HT was associated with a nearly fivefold increase in mortality during the first 7 days of life [mortality ratio (MR) = 4.81 (2.90-8.00)] and with increased mortality from 8 to 56 days of life [MR = 2.55 (1.29-5.04)]. HT is associated with excess mortality beyond the perinatal period up to at least 2 months of age, especially among low-birth-weight children. Hence, failure to comply with the WHO guidelines for care of newborns in low-income countries may have long-term consequences for child survival which have not previously been assessed. The WHO definition of HT should be based on mortality data.
