Prenatal Fish Oil Supplementation for Prevention of Childhood Asthma and Allergies: A Systematic Review and Meta-Analysis

Abstract Objective We conducted a systematic review and meta-analysis to determine the effectiveness of comprehensive community-based interventions with ≥ 2 components in improving asthma outcomes in children. Methods A systematic search of Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica Database (EMBASE), Cochrane Library and hand search of reference collections were conducted to identify any research articles published in English between 2000 and 2019. All studies reporting community-based asthma interventions with ≥ 2 components (e.g., asthma self-management education, home environmental assessment or care coordination etc.) for children aged ≤ 18 years were included. Meta-analyses were performed using random-effects model to estimate pooled odds ratio (OR) with 95% confidence intervals (CIs). Results Of the 2352 studies identified, 21 studies were included in the final analysis: 19 pre-post interventions, one randomised controlled trial (RCT) and one retrospective study. Comprehensive asthma programs with multicomponent interventions were associated with significant reduction in asthma-related Emergency Department (ED) visits (OR = 0.26; 95% CI 0.20–0.35), hospitalizations (OR = 0.24; 95% CI 0.15–0.38), number of days (mean difference = − 2.58; 95% CI − 3.00 to − 2.17) and nights with asthma symptoms (mean difference = − 2.14; 95% CI − 2.94 to − 1.34), use of short-acting asthma medications/bronchodilators (BD) (OR = 0.28; 95% CI 0.16–0.51), and increase use of asthma action plan (AAP) (OR = 8.87; 95% CI 3.85–20.45). Conclusion Community-based asthma care using more comprehensive approaches may improve childhood asthma management and reduce asthma related health care utilization.

Abstract Background: Prenatal exposure to omega-3 polyunsaturated fatty acids (n-3 PUFA) present in oily fish may prevent asthma or wheeze in childhood.Objective: By limiting this systematic review to fish oil intervention that commenced in the gestational period, we aim to find more clear evidences about the relationship between supplement with fish oil during pregnancy and the risk of asthma/wheeze in offspring, and to improve the life satisfaction of children who suffered asthma.Methods: A comprehensive literature search was conducted in the following database: PubMed, Medline, Web of Science, the Cochrane library, and Embase up to February 2021. Two reviewers independently selected studies, extracted data of the characteristics, and assessed risk of bias. Eight randomized controlled trials totaling 3,037 mother-infant pairs were analyzed in the end. “Allergic asthma” and “asthma and/or wheeze” were assessed in our meta-analysis. Subgroup analysis and sensitivity analysis were conducted. Dose–response data was examined using the robust-error meta-regression method.Results: This meta-analysis showed that n-3 PUFA during pregnancy did not significantly reduce the risk of asthma/wheeze (RR 0.93; 95% CI 0.82 to1.04, p=0.21) and allergic asthma (RR 0.66, 95% CI 0.24 to 1.86, p=0.44). Subgroup analyses revealed that the risk of childhood asthma/wheeze was significantly decreased: (1) in Europe (RR 0.69; 95% CI 0.53 to 0.89), (2) when the dose was ≥1200 mg/d (RR 0.69; 95% CI 0.55 to 0.88), (3) when supplementation started after gestational age 22 (RR 0.65; 95%CI 0.50 to 0.85), (4) when supplementation was from pregnancy to lactation (RR 0.69; 95% CI 0.51 to 0.95). Furthermore, the linear dose–response analysis showed that when maternal supplementation of n-3 PUFA increased by 100mg/d, the risk of asthma/wheeze was reduced by 2%.Conclusions: Although perinatal replenishment of n-3 PUFA did not prevent allergic disease in offspring, under some conditions, it could reduce the incidence of asthma/wheeze and allergic asthma in children, and the higher the dose, the better the protective effect it has. Additional research is needed to confirm the hypothesis of a link between n-3 PUFA intake and prevention of childhood asthma/wheeze.

Background: Perinatal depression is a common complication of pregnancy and can have severe and long-termadverse effects on both mother and infant. Randomized controlled trials (RCT) assessing the effect of fish oilsupplements on perinatal depression have shown mixed results.Objectives: We performed a systematic review and meta-analysis to assess the effects of fish oil supplementation during pregnancy on perinatal depression.Methods: A comprehensive search of MEDLINE (PubMed), EMBASE, and Cochrane Central Registry were conducted in adherence with the PRISMA guideline. Only RCTs published in English from January 2000 to date were included. The participants were pregnant women receiving fish oil supplementation or placebo. Summary effect measure of each study was converted to a common effect measure (log odds ratio) and its variance was calculated to estimate the pooled odds ratio and its 95% confidence Interval using random Effects model. Heterogeneity was assessed used restricted maximum likelihood method.Results: Nine trials were included in our analysis (2,979 women). Prevention Cohort (n = 5): Fish oil supplementation during pregnancy was associated with reduced risk of developing perinatal depression (OR: 0.87; CI: 0.076 to 0.99; p = 0.03). Treatment Cohort (n = 4) Fish oil supplementation during pregnancy was associated with reduced risk of persistent perinatal depression during postpartum period but did not reach statistical significance.Conclusion: In conclusion, a meta-analysis of included RCTs data shows a significant reduction in incidences of perinatal depression in women who received fish oil supplements during pregnancy. However, there was no evidence for a similar effect among women diagnosed with perinatal depression or women with major depressive disorder.

The Relationship

Introduction. Traffic related air pollution (TRAP) has long been associated with the onset of childhood asthma. The relationship between TRAP exposure and the development of childhood asthma phenotypes is less understood. To better understand this relationship, we performed a systematic review of the literature studying childhood TRAP exposure and the development of childhood asthma and wheezing phenotypes (transient, persistent, and late-onset asthma/wheezing phenotypes). Methods. A literature search was performed in PubMed, Embase, and Scopus databases for current literature, returning 1706 unique articles. After screening and selection, 7 articles were included in the final review. Due to the low number of articles, no meta-analysis was performed. Results. TRAP exposure appears to be associated with both transient and persistent asthma/wheezing phenotypes. However, there was little evidence to suggest a relationship between TRAP exposure and late-onset asthma/wheezing. The differing results may be in part due to the heterogeneity in study methods and asthma/wheezing phenotype definitions, in addition to other factors such as genetics. Conclusion. TRAP exposure may be associated with transient and persistent asthma/wheezing phenotypes in children. The low number of studies and differing results suggest that further studies are warranted.
