“…Four studies were included in our review .Three of the five risk factor combinations investigated showed a significant association with subsequent low lung function. [18,29,30,37] The longest duration of follow-up in those studies was 12 years. A 21 year follow-up study of babies born extremely prematurely has reported that any differences in lung function compared with termborn controls during childhood disappears in adult life.…”

It has been known for many years that multiple early life factors can adversely affect lung function and future respiratory health. This is the first systematic review to attempt to analyse all these factors simultaneously. We adhered to strict a priori criteria for inclusion and exclusion of studies.The initial search yielded 29,351 citations of which 208 articles were reviewed in full and 25 were included in the review. This included 6 birth cohorts and 19 longitudinal population studies. The 25 studies reported the effect of 74 childhood factors (on their own or in combinations with other factors) on subsequent lung function reported as percent predicted forced expiration in one second (FEV 1 ). The childhood factors that were associated with a significant reduction in future FEV 1 could be grouped as: early infection, bronchial hyper-reactivity (BHR) / airway lability, a diagnosis of asthma, wheeze, family history of atopy or asthma, respiratory symptoms and prematurity / low birth weight. A complete mathematical model will only be possible if the raw data from all previous studies is made available. This highlights the need for increased cooperation between researchers and the need for international consensus about the outcome measures for future longitudinal studies.

“…However, as the number of infants with BPD was low, it is impossible to make any comment related to the influence of BPD on wheezing, BA, and atopy. There is controversy related to the mechanism of the association between prematurity and allergy, BA, and atopy indicated by different studies (7,8,11,12,20,(31)(32)(33)(34)(35). The results of various studies and proposed mechanisms of atopy and allergic disease in premature infants involved genetic, perinatal origins, and environmental factors (36).…”

“…In premature infants, viral agents, especially RSV, most commonly cause respiratory system infections in early childhood, and RSV-induced bronchiolitis has been associated with wheezing and BA (20)(21)(22). Palivizumab reduces the severity of RSV infection in premature infants.…”

Wheezing, asthma, and atopy in premature infants at 2 years of age

et al. 2017

View full text Add to dashboard Cite

Background/aim: We aimed to evaluate wheezing, bronchial asthma (BA), and atopy in premature infants at 2 years of age via a crosssectional study.Materials and methods: Premature infants at <37 weeks of gestational age (GA) were assessed for atopy by skin-prick test and serum immunoglobulin E level at 2 years of age. The family's and infant's histories of allergy, BA, atopy, and wheezing were obtained by questionnaire and from hospital records.Results: There were 98 infants, with mean birth weight (BW) 1517.4 ± 486.5 g and GA 30.8 ± 2.9 weeks. The frequencies of wheezing, asthma, and bronchopulmonary dysplasia (BPD) were 32.7%, 16.3%, and 14.3%, respectively. Skin-prick tests were positive for 11 subjects, with allergy to cereals for 7 infants, egg for 3, and peanut for 1. Wheezing was related to GA, BW, respiratory distress syndrome, mechanical ventilation, sepsis, asphyxia, smoking, antenatal steroid, BA, palivizumab prophylaxis, number of people in the household, and duration of hospitalization (P < 0.05). Wheezing was negatively correlated to GA. Family history of BA, smoking, and number of people in the household were linked to BA (P < 0.05). Conclusion:Wheezing was related to degree of premature birth, but BA was linked to BA in the family and smoking. Increased gestation should improve the infant's respiratory health up to 2 years of age.

“…There is also evidence that infants with low birth weight, whose postnatal catch-up growth is rapid, are more likely to become overweight or obese as children (1,4) . Another highly debated association (5) is that between asthma and obesity, as is the relationship between low birth weight and impaired pulmonary function (6) . Nevertheless, the few studies that have investigated the relationship between the speed of weight gain in early life and the occurrence of asthma, allergies and impaired pulmonary function have yielded inconclusive results (7) .…”

Objective: To evaluate the association between weight gain in the first two years of life and the occurrence of wheezing, asthma, serum IgE, skin reactivity and pulmonary function. Design: Cohort study. Setting: The metropolitan region of Salvador, Bahia, Brazil. Subjects: The association was studied between 1997 and 2005 in 669 children up to 11 years of age. Data were collected on asthma and risk factors, both current factors and those present in the first years of life. Weight gain was considered fast when the Z-score was .0?67. Poisson regression was used in the multivariate statistical analysis. Results: Wheezing was reported in 25?6 % of the children. Weight gain was considered fast (Z-score .0?67) in 29?6 % of the children and slow (Z-score ,20?67) in 13?9 %. Children in the slow weight gain group had 36 % fewer symptoms of asthma (prevalence ratio 5 0?65; 95 % CI 0?42, 0?99). Conclusions: Slower weight gain in the early years of life may constitute a protective factor against symptoms of asthma. The relevance of this finding for public health is not yet certain, since it is known that children with slow and fast weight gain may be more likely to develop adverse health consequences related to both these situations.
