“…All of the drugs discussed above can be safely used during lactation. Breast-feeding should be encouraged as it appears to reduce the likelihood of the offspring developing asthma and other atopies [21], most likely due to the delay in introduction of cow's milk.…”

“…Data on active maternal smoking was collected by postal questionnaires sent in the first, second and third trimester of pregnancy and combined into smoking (no or yes). Postal questionnaires at the ages of 6 and 12 months provided information about breastfeeding and daycare attendance, and at the ages of 1-4 years about lower respiratory tract infections (pertussis, bronchitis, bronchiolitis or pneumonia) and doctor-attended eczema [18,21]. Weight and gestational age at birth and sex of the children were obtained from midwife and hospital registries.…”

Maternal weight, gestational weight gain and preschool wheezing: the Generation R Study

et al. 2013

We studied the associations of maternal pre-pregnancy body mass index and gestational weight gain with risks of preschool wheezing in offspring and explored the role of growth, infectious and atopic mechanisms.This substudy of 4656 children was embedded in a population-based birth cohort. Information about maternal pre-pregnancy weight, gestational weight gain and wheezing at the ages of 1-4 years was obtained by either physical measurements or questionnaires.Among mothers with a history of asthma or atopy, maternal pre-pregnancy obesity was associated with an overall increased risk of preschool wheezing (odds ratio 1.47, 95% confidence interval 1.12-1.95). Also, each standard deviation increase of gestational weight gain was associated with an increased overall risk of preschool wheezing (1.09, 1.04-1.14), was independent of pre-pregnancy body mass index and was not different between mothers with and without a history of asthma or atopy. Child's growth, respiratory tract infections or eczema did not alter the results.Mothers with pre-pregnancy obesity and a history of asthma or atopy, and mothers with higher gestational weight gain showed higher risks of wheezing in their offspring. These associations could not be explained by growth, infectious or atopic mechanisms. Further research is needed to identify underlying mechanisms and long-term consequences. @ERSpublications Pre-pregnancy obesity associated with increased risk of wheezing in offspring, if mothers have history of asthma or atopy

“…Breastfeeding was defined in this study as follows: (1) never, (2) partially through 4 months, (3) exclusively through 4 months. 24 Postnatal questionnaires completed by the mother at age 6 and 12 months included information on any day-care attendance (yes versus no), any vitamin D supplementation (yes versus no), and any history of doctorattended food allergy and eczema. Weight and height were measured at the child health centers during routine visits around age 48 months.…”

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.
