Abstract
The escalating global allergy epidemic has emerged as a pressing and persistent challenge, exerting a profound impact on human health systems across centuries. This burgeoning predicament can be attributed to contemporary lifestyles, environmental influences, and genetic predispositions. The manifestation of allergy-related factors exhibits dynamic fluctuations contingent on temporal shifts, geographical distinctions, cultural variances, and diverse demographic strata. In this review, we present recent epidemiological insights derived from two distinct birth cohorts: the Japan Environment and Children's Study (JECS), encompassing the entirety of Japan, and the Tokyo Children's Health, Illness, and Development Study (T-Child Study) within Tokyo. Through this comprehensive review, we offer a comprehensive overview of the latest epidemiological discoveries stemming from these pivotal Japanese birth cohorts, thereby affording a unique opportunity to deliberate on imperative strategies for the optimal management of the allergy epidemic.

Congenital hypothyroidism and thyroid function in a Japanese birth cohort: data from The Japan Environment and Children's Study. Clin Pediatr Endocrinol 2023; 32:213-220.

Abstract
The most common hormonal and metabolic disease in early childhood is congenital hypothyroidism (CH). This study aimed to describe CH in large-scale birth cohort data and summarize the results of serum thyroid-stimulating hormone (TSH) and free thyroxine (fT4) levels in 2-yr-old children. Data were obtained from the Japan Environment and Children's Study (JECS), and we identified 171 children with CH detected in newborn screenings or medical records (170.5 per 100,000 population). Infants with CH are at higher risk of developing congenital diseases than those without CH. Of 171 children with CH, 20 (11.7%) were diagnosed with congenital heart defects, 33 (19.3%) had chromosomal or other congenital abnormalities, and 23 (13.5%) had Down syndrome. At the age of 2 yr old, the median and 95% reference range values for TSH and fT4 were 2.13 (0.78-5.52) μIU/mL and 1.2 (1.0-1.5) ng/dL, respectively. Moreover, boys had slightly higher TSH and fT4 levels than did girls. Data on the distribution of TSH and fT4 in 2-yr-old children should be useful for decreasing the misclassification of thyroid disorders in the pediatric population. Trial-off treatment and re-evaluation of thyroid function are needed to classify permanent congenital hypothyroidism and transient congenital hypothyroidism after 3 yr of age.

Abstract
OBJECTIVE To evaluate the association between maternal asthma (MA) and obstetric complications, while considering subdivided total serum immunoglobulin E (IgE) levels. METHODS Data of the participants enrolled in the Japan Environment and Children's Study between 2011 and 2014 were analyzed. In total, 77,131 women with singleton live births at and after 22 weeks of gestation were included. MA was defined based on a self-administered questionnaire. Women with MA were stratified based on the quartile of total serum IgE levels during pregnancy as follows: low IgE levels (< 52.40 IU/mL), moderate IgE levels (52.40-331.00 IU/mL), and high IgE levels (> 331.00 IU/mL). The adjusted odds ratios (aORs) for preterm births (PTB), small for gestational age (SGA) infants, gestational diabetes mellitus, and hypertensive disorders of pregnancy (HDP) were calculated using multivariable logistic regression, while considering women without MA as reference and maternal socioeconomic factors as confounders. RESULTS The aORs for SGA infants and HDP in women with MA and high total serum IgE levels were 1.26 (95% confidence interval [CI], 1.05-1.50) and 1.33 (95% CI, 1.06-1.66), respectively. The aOR for SGA infants among women with MA and moderate total serum IgE levels was 0.85 (95% CI, 0.73-0.99). The aOR for PTB among women with MA and low total serum IgE levels was 1.26 (95% CI, 1.04-1.52). CONCLUSIONS FOR PRACTICE MA with subdivided total serum IgE levels was associated with obstetric complications. Total serum IgE level may be a potential prognostic marker to predict obstetric complications in pregnancies with MA.

Abstract
BACKGROUND The aim of this study was to explore the association between maternal allergies and preterm birth by different total immunoglobulin E (IgE) levels. METHODS Data of 81 791 pregnant women from the Japan Environment and Children's Study, a prospective birth cohort, were used. Maternal allergic diseases, including a history of bronchial asthma (BA), atopic dermatitis (AD), and allergic rhinitis (AR), were obtained by self-administered questionnaires. Total serum IgE levels were measured at the first trimester and obstetrical outcomes from medical records transcripts were analyzed. The association between maternal allergic disease and obstetric outcome, including threatened abortion, preterm labor, early preterm birth (22-33 weeks), and late preterm birth (34-36 weeks), were examined by logistic regression. Subgroup analyses were performed by IgE level. RESULTS Maternal BA and AR were associated with an increased risk of threatened abortion and preterm labor, but high total IgE level was associated with a decreased risk of preterm labor. There was little difference in associations between allergic disease and threatened abortion and preterm labor by total IgE levels. Although there was no significant association between allergic disease and preterm birth, if total IgE was high, AR was significantly associated with a decreased risk of early preterm birth (adjusted odds ratio, 0.60; 95% confidence interval 0.43-0.86). There was significant evidence for differences associated with total IgE levels (P-values for the interaction of the effects of AD and AR on early preterm birth were 0.039 and 0.015, respectively). CONCLUSIONS The effect of allergy on preterm birth might differ depending on the total IgE level.

Serum 25-Hydroxyvitamin D Concentrations and Atopic Dermatitis in Early Childhood: Findings from the Japan Environment and Children's Study. Nutrients 2021; 13:nu13082761.

Abstract
Vitamin D (VitD) may affect immune system modulation and result in the development of atopic dermatitis (AD). However, published findings have remained controversial. We investigated the association between early-life 25-hydroxyvitamin D (25(OH)D) levels and AD risk at childhood with a birth cohort. The data were obtained from “the Japan Environment and Children’s Study (JECS)” and “the Sub-Cohort study of JECS” performed with children aged 2 years. “Liquid chromatography-tandem mass spectrometry” was used to measure VitD. The information on AD was obtained from parents’ answers to a questionnaire when their children were aged 3 years. In order to explain the seasonal effects on VitD levels, a deseasonalized continuous variable was further calculated. The logistic regression models were fitted to evaluate the effect of VitD on childhood AD. The study included 4378 children with complete data on VitD and AD. The results from models indicated that low VitD at 2 years was not a risk factor for the development of AD at 3 years, after adjusting for potential confounders. Moreover, there was no U-shape relationship between deseasonalized VitD and childhood AD. Overall, early-life 25(OH)D levels were not link to the increased risk of developing childhood AD.

Association of Hemoglobin and Hematocrit Levels during Pregnancy and Maternal Dietary Iron Intake with Allergic Diseases in Children: The Japan Environment and Children's Study (JECS). Nutrients 2021; 13:nu13030810. [PMID: 33804474 PMCID: PMC7999127 DOI: 10.3390/nu13030810] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 02/20/2021] [Accepted: 02/24/2021] [Indexed: 12/21/2022] Open
Abstract
Few epidemiologic studies have examined the role of maternal iron status in allergic diseases in offspring and findings have been inconsistent. We used a large birth cohort in Japan to explore the association of the markers for maternal iron status (maternal hemoglobin, hematocrit and dietary iron intake during pregnancy) with allergy development in offspring during early childhood. We analyzed information on children age 0–3 years from the Japan Environment and Children’s Study (JECS). We used logistic models and generalized estimating equation models to evaluate the effect of maternal hemoglobin and hematocrit levels and dietary iron intake on allergies in children. Models were also fitted with propensity score-matched datasets. Data were collected for a total of 91,247 mother–child pairs. The prevalence (95% confidence interval) of low hemoglobin and hematocrit was 14.0% (13.7–14.2%) and 12.5% (12.3–12.8%), respectively. After adjusting confounders, low hemoglobin and hematocrit during pregnancy were not associated with childhood allergic outcomes. Findings from models with propensity score-matched datasets also indicated that children born to mothers with low hemoglobin or hematocrit levels during pregnancy did not have a higher risk of developing allergic conditions at 3 years old. We found no meaningful associations between low energy adjusted maternal dietary iron intake and allergies in children. In conclusion, using birth cohort data, we found no evidence supporting an association of low maternal hemoglobin, hematocrit and low dietary iron intake with allergy symptoms during early childhood. Further studies with more suitable proxy markers for blood iron status are needed.

Abstract
BACKGROUND It is suggested that maternal mental health during pregnancy may affect offspring immune and respiratory features, based on the developmental origins of health and disease hypothesis. OBJECTIVE To evaluate whether maternal quality of life (QoL) and depression during pregnancy leads to wheezing, asthma, and food allergy of the offspring at 3 years of age. METHODS We conducted a nationwide, multicenter, prospective birth cohort study, Japan Environment and Children's Study. All variables were collected from questionnaires. Health-related QoL was measured using the Medical Outcomes Survey Short Form-8 questionnaire with a physical component summary and a mental component summary score. We conducted logistic regression analyses to evaluate the associations of offspring's wheezing, asthma, and food allergy with maternal QoL and depression. RESULTS There were 72,685 participants with no missing variables. Maternal physical component summary scores of the Medical Outcomes Survey Short Form-8 questionnaire were negatively associated with offspring's asthma (adjusted odds ratio [aOR], 0.99; 95% confidence interval [CI], 0.99-1.00), current wheezing (aOR, 0.99; 95% CI, 0.99-0.99), and food allergy diagnoses (aOR, 0.99; 95% CI, 0.98-0.99) in children. Offspring's wheezing and asthma were also associated with maternal depression and anxiety during pregnancy. CONCLUSION Poor maternal prenatal QoL increased the risk of wheezing, asthma, and food allergy in offspring. In addition, maternal depression and anxiety increased the risk of offspring's wheezing, asthma, and food allergy.

Abstract
INTRODUCTION Previous studies have reported that maternal asthma increases the risk of preterm birth. We hypothesized that inflammatory reactions caused by allergic diseases might affect the uterine environment and, subsequently, perinatal outcomes. The objective of this study was to examine the associations between allergic features among mothers and preterm pregnancy outcomes in a nationwide birth cohort. METHODS We analyzed data from pregnant women obtained from the Japanese Environment and Children's Study (JECS), a nationwide general birth cohort study. We used binomial and multinomial logistic regression models to examine the associations between maternal allergic features and preterm birth, threatened preterm labor (TPL), and preterm premature rupture of the membrane (PPROM). RESULTS A total of 97,683 pregnant women were included. Prevalence of preterm birth, TPL, and PPROM was 4.7, 19.6, and 1.2%, respectively. Maternal history of allergic diseases (asthma, allergic rhinitis, allergic conjunctivitis, food allergy, drug allergy, and contact dermatitis) increased the risk of TPL(adjusted odds ratio [aOR] = 1.11 [95% CI: 1.06-1.17], aOR = 1.12 [1.08-1.16], aOR = 1.10 [1.04-1.16], aOR = 1.17 [1.09-1.26], aOR = 1.35 [1.23-1.48], and aOR = 1.34 [1.20-1.49], respectively). Although some maternal allergic features showed a negative association with preterm birth, the variables affecting preterm birth differed according to the gestational age of the fetus (22-33 weeks vs. 34-36 weeks). There were no significant associations between maternal allergic features and PPROM. CONCLUSION Maternal allergic disease, except atopic dermatitis, may increase the risk of TPL. Comorbidity of maternal allergic disorders and perinatal adverse outcomes require further investigation.

Association between maternal vegetable intake during pregnancy and allergy in offspring: Japan Environment and Children's Study. PLoS One 2021; 16:e0245782. [PMID: 33507986 PMCID: PMC7842951 DOI: 10.1371/journal.pone.0245782] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Accepted: 01/07/2021] [Indexed: 12/27/2022] Open
Abstract
The association between maternal diet during pregnancy and allergy in offspring remains contentious. Here, we examined the association between maternal intake of vegetables and related nutrients during pregnancy and allergic diseases in offspring at one year of age. A cohort of 80,270 pregnant women enrolled in the Japan Environment and Children's Study were asked to respond to a food frequency questionnaire during pregnancy and the International Study of Asthma and Allergies in Childhood questionnaire at one year postpartum. The women were categorized into quintiles according to the energy-adjusted maternal intake of vegetables and related nutrients. Using the categorizations as exposure variables, the adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were determined for the allergic outcomes, including asthma, wheeze, atopic dermatitis, eczema, and food allergy, in the offspring per quintile at one year of age. Of the 80,270 participants, 2,027 (2.5%), 15,617 (19.6%), 3,477 (4.3%), 14,929 (18.7%), 13,801 (17.2%), and 25,028 (31.3%) children experienced asthma, wheeze, atopic dermatitis, eczema, food allergy, and some form of allergic disease, respectively. The aORs of each quintile of maternal vegetable intake for all allergic outcomes were close to 1.0 compared to the lowest quintile. The lowest aOR was found in the association of maternal cruciferous vegetable intake with asthma (aOR: 0.82, 95% CI: 0.70-0.96) and highest was found in the association of maternal total vegetable intake with atopic dermatitis (aOR: 1.17, 95% CI: 1.04-1.31). The risk of allergic outcomes for the various nutrients related to vegetable consumption was close to 1.0. The maternal intake of vegetables and various related nutrients during pregnancy had little or no association with any of the allergic outcomes, including asthma, wheezing, atopic dermatitis, eczema, and food allergy, in offspring at one year.

Yamamoto-Hanada K, Pak K, Saito-Abe M, Yang L, Sato M, Irahara M, Mezawa H, Sasaki H, Nishizato M, Ishitsuka K, Ohya Y. Allergy and immunology in young children of Japan: The JECS cohort. World Allergy Organ J 2020; 13:100479. [PMID: 33204389 PMCID: PMC7652713 DOI: 10.1016/j.waojou.2020.100479] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 09/30/2020] [Accepted: 10/12/2020] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Capturing epidemiological signatures is essential to document burdens of disease and to design health care services, including prevention measures, clinical interventions, and policies. There are large geographical and ethnic variations in the epidemiology of allergic and immunological diseases. Various data are available from North America and Europe, but the epidemiology of allergic and immunological diseases in Asia is not well documented. OBJECTIVE To characterize epidemiological signatures of allergic and immunological disease in young children in Japan. METHODS This was a national, multicenter, prospective birth cohort study: Japan Environment and Children's Study (JECS). A general population of 103,060 women was enrolled during pregnancy. Allergic and immunological outcomes were assessed among young children using questionnaire data. RESULTS The prevalence of caregiver-reported immediate food allergy was 7.6%, 6.7%, and 4.9% at age 1, 2, and 3 years, respectively. Hen egg allergy was most common (5.4% prevalence at age 1 year) followed by allergies to cow milk and wheat. Several patterns of allergic symptom clusters were identified. Physician diagnosed, as reported by the caregiver, non-IgE mediated gastrointestinal food allergy affected 0.5% of infants. By contrast, caregiver-reported gastrointestinal food allergies affected 1.4% of children. Kawasaki disease affected 0.3% and 0.4% children, respectively, at age 1 and 3 years. Primary immunodeficiency disorders affected 0.005% children at age 3 years. CONCLUSION These data provide important epidemiological signatures of allergy and immunology in young Japanese children including the age-specific prevalence of allergic disease, Kawasaki disease, and primary immune deficiency.
