Environmental control measures for the management of atopy

Association between pet ownership and physical activity levels, atopic conditions, and mental health in Singapore: a propensity score-matched analysis

Although existing literature increasingly suggests a positive influence of pet ownership on human physical activity levels, results from many European, American, and Japanese studies have been inconsistent. How pet ownership impacts mental health and atopy is likewise controversial and whether distinct demographic subgroups experience differential effects is unclear. This cross-sectional study surveyed participants (n = 823) via a self-administered online questionnaire. Comparisons of outcomes between pet owners and non-pet owners with subgroup analyses were performed within a propensity score-matched subset (n = 566) of respondents. There were no differences in physical activity levels or mental health scores between pet owners and non-pet owners. In subgroup analyses, compared to non-pet owners, main pet caregivers reported 14.1 (95% CI 2.79–25.3) and 19.0 (95% CI 4.70–33.3) more minutes per week of moderate- and vigorous-intensity physical activity respectively and higher SF-36 emotional well-being (β = 2.7, 95% CI 0.100–5.32) and energy scores (β = 3.8, 95% CI 0.410–7.27). Age was a significant effect modifier of the association between pet ownership and emotional well-being, energy and social functioning scores, with greater scores above the ages of 39, 35 and 39 years old respectively (interaction p = 0.043, 0.044, 0.042). Finally, pet acquisition was associated with worsening of allergic rhinitis, while pet ownership cessation was associated with improvement of allergic rhinitis and eczema symptoms. To our knowledge, this is the first study addressing the public health impact of pet ownership in Southeast Asia and its findings add contextual nuance to suggest potential benefits derived from pet ownership.

Diagnosis and Management of Allergic Rhinitis in Children

Allergic rhinitis is one of the most common chronic diseases managed by pediatricians. It can result in a significant burden of disease for the patient and their family. This article reviews classification of this condition as well as its pathophysiology, mediated by a Th2 lymphocyte response. Methods of diagnosis via elicitation of a thorough history, focused physical examination, and testing for specific allergen sensitization are discussed. Treatment of this condition is examined, focusing on allergen avoidance and a variety of available pharmacotherapies. Finally, allergen immunotherapy modalities and their potential for disease-modifying effects as well as their potential risks and benefits are outlined. [Pediatr Ann. 2019;48(12):e485-e488.].
