Hormone therapy use in the Canadian Longitudinal Study on Aging: a cross-sectional analysis
Conclusions:These findings provide a recent national picture of HT use in Canada that may be used to inform opportunities for improved physician–patient communication regarding menopause management. Objective: The aim of the study was to assess the prevalence and factors associated with hormone therapy (HT) use among Canadian women. Methods: Baseline data from the Tracking cohort of the Canadian Longitudinal Study on Aging (CLSA) was used for this analysis. The main outcome was HT use among women aged 45-85 years, defined as current, past, and never users. Multinomial logistic regression models were used to examin...

Predictors of early and late onset asthma in a rural population of children: The Saskatchewan Rural Health Study
Conclusion: While a history of allergy may not be time dependent for asthma onset, farm exposure may be more limited to preventing early asthma onset.

Sex-specific impact of asthma during pregnancy on infant gut microbiota
This study aimed to determine whether lactobacilli and other microbes are reduced in the gut of infants born to an asthmatic mother, and whether this differs by the sex of the infant. Mother-infant pairs (N=1021) from the Canadian Healthy Infant Longitudinal Development full-term cohort were studied. The abundance of infant faecal microbiota at 3–4 months, profiled by gene sequencing, was compared between both women with and without asthma treatment during pregnancy. Infant sex, maternal ethnicity, pre-pregnancy overweight and atopy status, birth mode, breastfeeding status and intrapartum antibiotic treatment we...

Study finds asthma and food allergies predictable at age 1
(McMaster University) Using data from more than 2,300 children from across Canada participating in the CHILD Study, the researchers evaluated the presence of AD and allergic sensitization at age one. When the children were three years of age, the researchers performed a clinical assessment to determine the presence of asthma, allergic rhinitis, food allergy and AD.

Epidemiology of Food Allergy
Understanding the epidemiology of food allergy is complicated by the difficulty of identifying it on a large scale. The prevalence of food allergy is higher in younger age groups and decreases with age. Allergy to peanut and egg seems to be more common in Northern Europe, the United States, Canada and Australia compared with Southern Europe, Eastern Europe and Asia, whereas shellfish and fish allergies may be more common in Asia. The rate of transient unrecognized food allergy may be high and variable recognition of food allergy may explain some of the differences seen in food allergy prevalence.

Residential Air Pollution and Associations with Wheeze and Shortness of Breath in Adults: A Combined Analysis of Cross-Sectional Data from Two Large European Cohorts
Conclusion: Exposure to PM and NO2 air pollution was associated with the prevalence of wheeze and shortness of breath in this large study, with stronger associations between PM2.5 and both outcomes among lower- versus higher-income participants. https://doi.org/10.1289/EHP1353 Received: 13 November 2016 Revised: 10 August 2017 Accepted: 14 August 2017 Published: 29 September 2017 Address correspondence to D.

Updated Global Estimates of Respiratory Mortality in Adults ≥ 30 Years of Age Attributable to Long-Term Ozone Exposure
Conclusions: These findings suggest that the potential magnitude of health benefits of air quality policies targeting O3, health co-benefits of climate mitigation policies, and health implications of climate change-driven changes in O3 concentrations, are larger than previously thought. https://doi.org/10.1289/EHP1390 Received: 17 November 2016 Revised: 19 June 2017 Accepted: 20 June 2017 Published: 28 August 2017 Address correspondence to C.S.

Examining Guidelines for School-Based Breakfast Programs in Canada: A Systematic Review of the Grey Literature.
Abstract School breakfast programs are widespread and serve varying objectives regarding youth health promotion. Evidence-based guidelines for breakfast programs may be important in maximizing their effectiveness related to student outcomes, yet it is unclear what is available in Canada. A systematic review was conducted to identify and compare Canadian guidelines related to breakfast programs. Data sources included grey literature databases, customized search engines, targeted websites, and content expert consultations. Eligible guidelines met the following criteria: government and nongovernment sources at the fe...

Prevalence of non-food allergies among non-immigrants, long-time immigrants and recent immigrants in Canada.
CONCLUSION: This study finds a distinctly lower prevalence of non-food allergies among immigrants compared with non-immigrants, with the difference diminishing with longer duration of residence in Canada. The findings highlight the potential of environmental determinants of allergy development that warrant further investigation, and demonstrate the need for multicultural strategies to manage the public health burden of allergic conditions.
