BACKGROUND: Associations between ambient particulate matter < 2.5 μm (PM2.5 ) and asthma morbidity have been suggested in previous epidemiologic studies but results are inconsistent for areas with lower PM2.5 levels. We estimated the associations between early-life short-term PM2.5 exposure and the risk of asthma or wheeze clinical encounters among Massachusetts children in the innovative Pregnancy to Early Life Longitudinal (PELL) cohort data linkage system. METHODS: We used a semi-bidirectional case-crossover study design with short-term exposure lags for asthma exacerbation using data from the PELL system...

OBJECTIVE: The association of maternal pregnancy diet with offspring asthma risk have been reported. However, literature on longitudinal patterns of asthma risk relative to intrauterine nutrient exposure is limited. We aimed to establish whether vegetable, oily fish and vitamin D intake during pregnancy are associated with childhood asthma risk over a 10-year period in the Irish Republic. DESIGN: Mother-child pairs (n=897) from the Lifeways prospective birth cohort, with data on nutrient intake during pregnancy and asthma status, respectively, were eligible for inclusion in the analysis...

REVIEW
Rosa M Pacheco-González, Luis García-Marcos, Eva Morales
Prenatal vitamin D status may influence offspring's respiratory and allergic outcomes; however, evidence is inconclusive. A systematic review and meta-analysis was conducted on the association between 25-hydroxyvitamin D [25(OH)D] levels in maternal blood in pregnancy or cord blood at birth with the risk of offspring's respiratory and allergic conditions. Two independent researchers conducted systematic searches for observational studies published until May 2017 using defined keywords on vitamin D and health outcomes, including respiratory tract infections (RTIs), wheeze, asthma, atopic eczema, allergic rhinitis, allergic sensitization, and lung function...

BACKGROUND/OBJECTIVES: Vegetable intake during childhood may reduce the risk of subsequent asthma. We verified the effect of maternal intake during pregnancy on asthma risk in offspring, which has rarely been studied. SUBJECTS/METHODS: In a hospital-based birth cohort study conducted in Tokyo, we administered a food frequency questionnaire at two periods during the respondents' pregnancy: early and mid to late periods. In addition, a questionnaire including the International Study of Asthma and Allergies in Childhood questionnaire was conducted when the offspring were 2 years old...

BACKGROUND: In a randomised placebo-controlled trial, we previously found that the probiotic Lactobacillus rhamnosus HN001 (HN001) taken by mothers from 35 weeks gestation until 6 months post-partum if breastfeeding and their child from birth to age 2 years halved the risk of eczema during the first 2 years of life. We aimed to test whether maternal supplementation alone is sufficient to reduce eczema, and compare this to our previous study when both mothers and their child were supplemented...

Asthma most frequently develops early in life, and increased recognition of the role of lifestyle and environmental factors in asthma susceptibility raises the possibility that dietary exposures during pregnancy may influence risk of asthma in offspring. This review discusses the latest evidence with regard to the effect of diet during pregnancy on childhood asthma risk, including potential mechanisms, outcomes of randomized clinical trials, and results from observational studies. Vitamin D and polyunsaturated fatty acid intake during pregnancy are highlighted as areas with large and growing bodies of literature to support a potential role in prenatal modulation of subsequent asthma risk...

Introduction Despite the considerable and increasing proportion of women of reproductive age with a chronic non-communicable disease (NCD) and the potential adverse implications of many NCDs for childbearing, little is known about the fertility management experiences of women with an NCD, including their contraceptive use, pregnancy experiences and outcomes, and reproductive health care utilisation. The aim of this study was to investigate the fertility management experiences of women with an NCD and draw comparisons with women without an NCD...

Background: Misconceptions about medications' safety can lead pregnant women with asthma to stop their medications, resulting in asthma-related neonatal morbidity and mortality. Our aim was to assess the level of pregnancy-related asthma knowledge and education about asthma medications' safety, among women of childbearing age with a history of bronchial asthma. Methods: A cross-sectional survey of convenience sample of outpatient clinic attendees of Pulmonary, Family Medicine and Obstetrics & Gynecology among women of childbearing age with history of asthma at King Abdulaziz Medical City, Riyadh, Saudi Arabia...

PURPOSE OF REVIEW: The current review addresses the importance of the prospective cohort design in large, unselected populations starting early in life for understanding the origins of childhood health disorders. RECENT FINDINGS: Cohort studies originating in healthy populations have contributed to great advances in health, especially in cardiovascular diseases, but have only recently been applied systematically to study the origins of childhood disorders. Several large population-based pregnancy and/or birth cohorts have been developed in different parts of the world, and these are beginning to contribute to better understanding of the underlying causes of rare but important childhood disorders, such as autism...

BACKGROUND: Prenatal and postnatal paracetamol exposure has been previously associated with asthma development in childhood in Western populations. We explore the association between prenatal and postnatal paracetamol exposure and asthma development in a Central European sample of Czech children, suggesting possible additive effect of the both exposures. Furthermore, since aspirin had been used more widely during study data collection in Central Europe, we also compared asthma development for those exposed to paracetamol and aspirin...
