MORENO, Sandra Janneth et al. Incidence and associated factors to wheezing in infants, Bucaramanga Metropolitan Area, Colombia. Rev. Univ. Ind. Santander. Salud [online]. 2011, vol.43, n.2, pp.131-140. ISSN 0121-0807.

Introduction: Bronchoobstructive disease in infants is frequent cause of assistance to primary and emergency services, and hospitalization, too. These are recurrent or non-recurrent, with long-term sequelae. Objective: To establish the incidence and associated factors for developing wheezing syndrome (WS) and its recurrence during the first two years of life. Methodology: A retrospective cohort. A survey was conducted to determine wheezing incidence, age at first crisis, event number in the first two years of life, and aspects previously recognized as risk factors. It was estimated incidence rate and likelihood of being free of WS at two years, as well as the associated factors with recurrent and non-recurrent WS. Results: We studied 139 boys and 159 girls dwelling in the Bucaramanga Metropolitan Area, Colombia. The incidence rate for two years is 1.22 events/100 person-months (95%CI 0,97-1,47), with a potential to reach the second birthday without WS of 67.0% (95%CI 60.7 to 72.4%). Associated factors with non-recurrent WS were family history of recurrent rhinitis (RR 2.56) or asthma (RR 2.11), and live with smokers (RR 2.00); for recurrent WS were a family history of rhinitis (RR 8.79 ) or asthma (RR 3.43), consumption of allergenic food (RR 6.82), perinatal asphyxia (RR 6.36), to attend kindergarten (RR 3.37), and to be living with children under 10 years (RR 1,63). Discussion: The incidence of WS is similar to others found in developed countries. Many risk factors are preventable, and their intervention would help to reduce the risk to suffer WS.
