“…We found a significant interaction between prematurity and maternal smoking in utero on the outcome of number of episodes of wheezing, but not on the outcome of recurrent wheezing (≥4 episodes of wheeze) which has been suggested to be an important predictor of asthma in some studies. 29 Our finding that prematurity was associated with an increased risk of recurrent wheezing is in keeping with the literature. A number of studies including a meta-analysis of 19 papers 10 suggest that children born prematurely have an increased risk of asthma and wheezing when compared to term babies.…”

“…The ''Western'' diet in this study was characterised by high intake of refined grains, soups and sauces, savoury and snacks, other fats, sugar-containing beverages and meat. Although no other studies examined the overall effect of a ''Western-like'' diet in childhood on the development of asthma-related symptoms in children, a French study did find a ''Western'' dietary pattern to be associated with an increased risk of frequent asthma attacks in (2) 4 months exclusive, partially at 6 months 371 (17) 387 (18) 4 months exclusive, no breastfeeding at 6 months 153 (7) 161 (7) 6 months partially 172 (8) 185 (9) 4 months partially, no breastfeeding at 6 months 1008 ( adult females [15]. Individual food components of a ''Western'' diet in childhood have been found to be associated with asthma symptoms in children.…”

Overall diet in early childhood may affect the development of respiratory symptoms. This study examined whether childhood dietary patterns are associated with respiratory symptoms in Dutch pre-school children, and whether this association could be explained by energy intake.A prospective cohort study was performed in 2,173 children aged f4 yrs. Data on asthma-related symptoms were obtained by questions from the age-adapted version of the "International Study of Asthma and Allergies in Childhood" questionnaires. Data on respiratory tract infections, defined as episodes of physician attended fever with respiratory symptoms, was obtained by questionnaire. Principal components analysis was used to develop dietary patterns at 14 months of age.Compared with low adherence, high adherence to the ''Western'' dietary pattern was significantly associated with frequent wheeze at 3 yrs of age (relative risk (RR) 1.39, 95% CI 1.02-1.89) and frequent shortness of breath (RR 1.44, 95% CI 1.03-2.01) and respiratory tract infections (RR 1.54, 95% CI 1.08-2.19) at 4 yrs of age. However, this association was partially explained by energy intake.A ''Western'' diet may increase the risk of frequent respiratory symptoms at 3 and 4 yrs of age. In some measure, this association was explained by energy intake.

OBJECTIVE: To assess whether timing of introduction of fish and the amount of fish consumption in infancy were associated with asthmalike symptoms at preschool age. METHODS: This study was embedded in the Generation R study (a population-based birth cohort in Rotterdam, Netherlands). At the age of 12 and 14 months, timing of introduction of fish into the infant’s diet was assessed. The amount of fish consumption at 14 months was assessed by a semiquantitative food frequency questionnaire. Presence of asthmalike symptoms in the past year was assessed at the child’s age of 36 and 48 months. RESULTS: Relative to no introduction in the first year of life, introduction between age 6 and 12 months was significantly associated with a lower risk of wheezing at 48 months (odds ratio [OR]: 0.64; 95% CI: 0.43–0.94). When compared with introduction between 6 and 12 months, no introduction in the first year and introduction between 0 and 6 months were associated with an increased risk of wheezing at 48 months (OR: 1.57; 95% CI: 1.07–2.31 and OR: 1.53; 95% CI: 1.07–2.19, respectively). The amount of fish at age 14 months was not associated with asthmalike symptoms (P > .15). CONCLUSIONS: Introduction of fish between 6 and 12 months but not fish consumption afterward is associated with a lower prevalence of wheezing. A window of exposure between the age of 6 and 12 months might exist in which fish might be associated with a reduced risk of asthma.
