The following factors contribute to hypothermia in preterm babies except
Decreased subcutaneous fat and brown fat
Large surface area in relation to body weight
Less oxygen consumption
Increased muscular activity
Increased muscular activity generates heat. Increased physical activity(crying, increased body movements) is a compensatory mechanism to generate heat in a neonate on exposure to cold and wet environment. Reference : page 143 Ghai Essential Pediatrics 8th edition
