“…We measured the main respiratory symptom outcome in our study using International Study on Asthma and Allergy in Childhood questionnaires. Although this method is validated from the age of 7 years, it is widely accepted in epidemiological studies among younger children [32][33][34] , and reliably reflects the incidence of asthma symptoms in young children. 35 An earlier Dutch birth cohort study used identical International Study on Asthma and Allergy in Childhood questions, and observed similar prevalences of wheezing based on the International Study on Asthma and Allergy in Childhood questionnaires as in our study.…”

“…35 An earlier Dutch birth cohort study used identical International Study on Asthma and Allergy in Childhood questions, and observed similar prevalences of wheezing based on the International Study on Asthma and Allergy in Childhood questionnaires as in our study. 32 In preschool children, a diagnosis of asthma is based on symptoms. Objective tests, including spirometry or bronchial hyper responsiveness, are difficult to perform in young children and have limited applicability.…”

Maternal fish consumption during pregnancy and risks of wheezing and eczema in childhood: The Generation R Study

BACKGROUND/OBJECTIVES: Maternal fish consumption during pregnancy might influence the fetal immune system through anti-inflammatory effects of omega-3 fatty acids, and might affect the risks of childhood asthma and atopy. In Generation R, a prospective cohort study in the Netherlands, we examined the associations of first trimester fish consumption with childhood wheezing and eczema in the first 4 years of life. METHODS: In total, 2976 mothers completed a 293-item semiquantitative food frequency questionnaire covering dietary intake in the first trimester. The occurrence of wheezing and eczema was yearly assessed by questionnaires. RESULTS: Median weekly fish consumption was 83 (95% range 0-316) grams per week. We observed no consistent associations of maternal total-, lean-or fatty-fish consumption during pregnancy with the risks of childhood wheezing. Maternal shellfish consumption of 1-13 g per week was associated with overall increased risks of childhood wheezing and eczema (OR 1.20 (1.04, 1.40) and OR 1.18 (1.01, 1.37), respectively). Maternal fatty fish consumption of 35-69 g per week was associated with increased overall risks of childhood eczema (OR 1.17 (1.00, 1.38)), but maternal total-or lean-fish consumption was not. CONCLUSIONS: During pregnancy, shellfish consumption was associated with increased risks of wheezing and eczema, while fatty fish consumption was associated with a higher risk of eczema only. Maternal total fish or lean fish consumption were not associated with wheezing or eczema. Further studies are needed to replicate these findings and to explore underlying mechanisms.

“…Preterm birth has been consistently associated with a higher prevalence of wheezing illness and deficits in lung function measures in childhood (14,15) . Early life diet could modulate the likelihood of childhood asthma by affecting fetal airway development and/or influencing the initial early life interactions between allergens and the immune system by promoting Th-cell differentiation towards the Th2 cell type (16) .…”

Objective: To discuss current evidence about the relation between prenatal and childhood Mediterranean diet, and the development of asthma and allergies in children. Design: Review of the literature. Setting and results: Four recent studies conducted in Mediterranean countries (Spain, Greece) and one conducted in Mexico evaluated the association between childhood Mediterranean diet and asthma outcomes in children.

“…[3][4][5][6][7][8] The risks of these infectious diseases are affected by several factors including birth weight, gestational age, socioeconomic status, ethnicity, number of siblings, day care attendance, and parental smoking. 3,5,6,[8][9][10][11][12][13][14][15][16][17][18][19][20] Breastfeeding has been suggested as a modifiable influencing factor. When given exclusively, breastfeeding reduces the risk of infectious diseases in infants in developing countries.…”

Prolonged and Exclusive Breastfeeding Reduces the Risk of Infectious Diseases in Infancy

WHAT'S KNOWN ON THIS SUBJECT:Exclusive breastfeeding seems to decrease the risk of infectious diseases in infancy. However, the World Health Organization has called for more research regarding the benefits for 6 months instead of 4 months of exclusive breastfeeding. WHAT THIS STUDY ADDS:Exclusive breastfeeding to the age of 6 months tended to be more protective than exclusive breastfeeding until the age of 4 months and partially thereafter. Our findings support health-policy strategies that promote exclusive breastfeeding for 6 months in industrialized countries. abstract OBJECTIVE: To examine the associations of duration of exclusive breastfeeding with infections in the upper respiratory (URTI), lower respiratory (LRTI), and gastrointestinal tracts (GI) in infancy. METHODS:This study was embedded in the Generation R Study, a population-based prospective cohort study from fetal life onward in the Netherlands. Rates of breastfeeding during the first 6 months (never; partial for Ͻ4 months, not thereafter; partial for 4 -6 months; exclusive for 4 months, not thereafter; exclusive for 4 months, partial thereafter; and exclusive for 6 months) and doctor-attended infections in the URTI, LRTI, and GI until the age of 12 months were assessed by questionnaires and available for 4164 subjects. RESULTS:Compared with never-breastfed infants, those who were breastfed exclusively until the age of 4 months and partially thereafter had lower risks of infections in the URTI, LRTI, and GI until the age of 6 months (adjusted odds ratio . Similar tendencies were observed for infants who were exclusively breastfed for 6 months or longer. Partial breastfeeding, even for 6 months, did not result in significantly lower risks of these infections. CONCLUSIONS:Exclusive breastfeeding until the age of 4 months and partially thereafter was associated with a significant reduction of respiratory and gastrointestinal morbidity in infants. Our findings support healthpolicy strategies to promote exclusive breastfeeding for at least 4 months, but preferably 6 months, in industrialized countries.

Respiratory Symptoms in the First 7 Years of Life and Birth Weight at Term

Abstract: A lower birth weight in children born at term is associated with a transiently increased risk of respiratory symptoms. This effect is enhanced by environmental tobacco smoke exposure.
