Relationship between low birth weight and respiratory symptoms in a cohort of primary school children

Prenatal risk factors and occurrence of allergic rhinitis among elementary school children in an urban city

“…Frischer et al [20] reported that asthma was significantly more prevalent among children with birth weights less than 2500 g; however, no significant correlation was observed between low birth weight and the occurrence of allergic rhinitis in our study. Since the numbers of subjects in both studies were small, further studies with greater numbers of subjects and greater detail in the stratification of birth weights are necessary to clarity this issue.…”

“…Since the numbers of subjects in both studies were small, further studies with greater numbers of subjects and greater detail in the stratification of birth weights are necessary to clarity this issue. Several studies report a greater asthma or allergic disease rates in higher socioeconomic classes [20,21], but others reported no such association [9,22]. We used parental education to represent socioeconomic class in our study; both maternal and paternal educational levels showed no significant correlations with allergic rhinitis.…”

Natural History of Serum Immunoglobulin Concentrations in Low Birth Weight Infants and Association with Respiratory Tract Infections

“…The present data suggest that preterm infants may be more susceptible to bronchitis as compared to the control infants. Other studies provide support for this: Frischer et al [25] described a higher frequency of respiratory symptoms, such as examination-induced cough, in school-aged children born with a birth weight below 2,500 g. A higher prevalence of wheezing was observed during the first 2 years of life in children with a birth weight of ^1,500 g compared to those born with more than 2,500 g [26].…”

Gestational age and occurrence of atopy at age 31—a prospective birth cohort study in Finland

“…Similar associations, although non‐significant for atopic dermatitis, were also observed in the present study population (data not shown). On the other hand, several [19,21–23] but not all [24–26] studies have shown prematurity to be associated with the risk of respiratory symptoms and asthma in childhood. However, consistent with the present results, none of the studies on adults have shown an association between gestational age and asthma [10,27,28].…”
