Ji X, Yao Y, Zheng P, Hao C. The relationship of domestic pet ownership with the risk of childhood asthma: A systematic review and meta-analysis. Front Pediatr 2022; 10:953330. [PMID: 35935350 PMCID: PMC9352935 DOI: 10.3389/fped.2022.953330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Accepted: 07/04/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND AND OBJECTIVE The relationship between pet ownership and childhood asthma remains controversial. In recent years, there have been increasing studies with large sample size. Therefore, we conducted this systematic review and meta-analysis to evaluate the relationship between pet ownership and childhood asthma. METHOD Relevant research was retrieved from PubMed, Cochrane, EMBASE, and Web of science. The retrieval was as of October 1, 2021. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of the included studies. Stata 15.0 was used to conduct the meta-analysis. RESULTS A total of 60 studies with large sample size published between 1995 and 2021 were included in this systematic review and meta-analysis, which included 18 cohort studies and 42 case-control studies covering 27 countries and 1,871,295 children. As shown by meta-analysis results, cat ownership (OR = 1.18, 95%CI: 1.05∼1.33) and dog ownership (OR = 1.12, 95%CI: 1.0 0∼1.24) have a significant bearing on the occurrence of childhood asthma. Pet ownership was also positively correlated with the occurrence of severe childhood asthma (OR = 1.15, 95%CI: 1.11∼1.20). CONCLUSION Pet ownership, especially cats and dogs, is associated with the occurrence of asthma in children.

Abstract
The prevalence of children allergic rhinitis has been increasing in China and associated factors still are not clear. In the present paper, we selected 13,335 parent-reported questionnaires of 4-6 years-old children, in a cross-sectional study from April 2011 to April 2012 in Shanghai city, and investigated associations of various factors with parent-reported allergic rhinitis (doctor-diagnosed) and rhinitis symptoms in childhood. After adjusted by age, sex, family history of atopy, and respondent of questionnaire, we find that no siblings, mother in older age during pregnancy, shorter breastfeeding, using antibiotics in the first year, and home dampness-related exposures, had significant associations with increased prevalence of the studied diseases. Location, type, building area, decoration materials and construction period of the residence, also had significant associations with these diseases. Current parental smoking and pet-keeping had no significant associations with the studied diseases. Incense-burning and using mosquito coils had significant associations with reduced risk of allergic rhinitis and with increased risk of rhinitis symptoms. Using air cleaner and cleaning the residence in high frequency had associations with increased risk, but eating fast food and ice cream often had associations with the reduced risk, of the studied diseases. Families with children being diagnosed allergic rhinitis likely change their lifestyle behaviors. In conclusion, childhood rhinitis could be influenced by heredity and many "environmental exposures". Avoidance behaviors and reverse causation in parental smoking, pet-keeping, and dietary habits for childhood rhinitis should be carefully considered.

Home Dampness Signs in Association with Asthma and Allergic Diseases in 4618 Preschool Children in Urumqi, China-The Influence of Ventilation/Cleaning Habits. PLoS One 2015; 10:e0134359. [PMID: 26230849 PMCID: PMC4521786 DOI: 10.1371/journal.pone.0134359] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2015] [Accepted: 07/09/2015] [Indexed: 12/20/2022] Open
Abstract
There is an increasing prevalence of childhood asthma and allergic diseases in mainland of China. Few studies investigated the indoor dampness, ventilation and cleaning habits and their interrelationship with childhood asthma and allergic diseases. A large-scale cross-sectional study was performed in preschool children in Urumqi, China. Questionnaire was used to collect information on children’s health, home dampness and ventilation/cleaning (V/C) habits. Multiple logistic regressions were applied to analyze the associations between childhood asthma/allergic diseases and each sign of home dampness, dampness levels, each V/C habit and total V/C scores. The associations between dampness and health were further performed by strata analyses in two groups with low and high V/C scores. Totally 4618(81.7%) of 5650 children returned the questionnaire. Reports on home dampness were most common for water condensation on windows (20.8%) followed by damp beddings (18.0%). The most common ventilation measure was the use of exhaust fan in bathroom (59.3%), followed by daily home cleaning (48.3%), frequently putting beddings to sunshine (29.9%) and frequently opening windows in winter (8.4%). There were positive associations between the 6 signs of home dampness and children’s health particularly the symptoms last 12 months. By comparing with the reference dampness level (dampness scored 0), both the low dampness (scored 1~2) level and the high dampness level (scored 3~6) showed significantly increasing associations with childhood symptoms. There were crude negative associations between V/C habits and childhood health but not significant adjusting for home dampness levels. The risks of home dampness on children’s health were lower in the group with higher V/C score but the differences were not statistically significant. Home dampness is a potential risk factor for childhood asthma and allergic symptoms in preschool children in Urumqi, China. No significant effects were observed for ordinary home ventilation and cleaning habits in reducing the risks of home dampness on childhood asthma and allergic diseases in Urumqi, China.

Abstract
Worldwide, many nonsmokers (often women and children) are exposed to second-hand smoke (SHS) in home settings, as men retain their traditional power and control within their family and women and children have limited agency to intervene. This study, set up to explore home smoking management in rural China, found that some women were able to positively intervene to restrict men's smoking at three key stages: prior to conception, during their pregnancy and at the early years of their children's lives. By utilizing dominant social, health and political narratives about the importance of raising a healthy child supported by the One-Child Policy in China, combined with the fear of health risks of SHS to young children, the women were able to use their elevated status as bearer and carers of the only children to subvert the pre-eminence of men in domestic environments, enabling them to positively influence home smoking. While this study highlights the possibility for future smoking cessation initiatives in China by incorporating family carers' elevated awareness of protection of children's health in key stages of childhood, there is also a need for further health education, as family members were unsure why they needed to keep children smoke-free, which may partially explain why few households were smoke-free.

Abstract
BACKGROUND The prevalence of asthma among Shanghai children has increased over time. This increase might be associated with changes in environmental exposures. Investigation of the time-trend of asthma and current prevalences is essential to understanding the causes. OBJECTIVE To estimate the current prevalences of asthma, allergies and other respiratory symptoms among Shanghai preschool children, and to investigate the time-trend of childhood asthma prevalence of from 1990 to 2011. METHODS From April 2011 to April 2012, the CCHH (China, Children, Homes, Health) cross-sectional study was conducted in Shanghai. Questionnaires were distributed to 17,898 parents or guardians of preschool children from 72 kindergartens in 5 districts. Previous similar studies were also summarized by a systematic literature review. RESULTS From a total of 14,884 questionnaires for 3-7 year old children, prevalences of the following diseases and symptoms were calculated: asthma 10.2%, wheeze (ever) 28.1%, pneumonia (ever) 33.5%, otitis media 11.0%, rhinitis (ever) 54.1%, hay fever 12.2%, eczema (ever) 22.7%, and food allergy 15.7%. Urban children had higher prevalences of most symptoms than suburban children. The prevalence of asthma has increased significantly, almost five-fold, from 2.1% in 1990 to 10.2% in the present study. The prevalence of asthma in boys was higher than in girls in the present study and in all reviewed studies. CONCLUSIONS Asthma, allergy and airway symptoms are common among preschool children in Shanghai. The prevalence of childhood asthma in Shanghai has increased rapidly from 1990 to 2011.

Abstract
BACKGROUND China is home to the largest number of smokers in the world; more than half of the male population smoke. Given the high rates of Chinese immigration to Canada and the USA, researchers have explored the effect of immigration on Chinese smokers. Reduced tobacco use among Chinese immigrants has been reported in the United States; however, little is known about the social factors underlying men's smoking practices in settings where tobacco control measures have denormalized smoking, and in the context of fatherhood. The purpose of this Canada-based study was to explore the smoking-related experiences of immigrant Chinese fathers. METHODS In this qualitative study, semi-structured telephone interviews were conducted with 22 Chinese Canadian fathers who smoked or had recently quit smoking, and had at least one child under the age of five years old. RESULTS The Chinese fathers had dramatically changed their smoking patterns due to concern for their children's health and social norms and restrictions related to smoking in Canada. The facilitators and barriers for men's smoking were intertwined with idealized masculine provider and protector roles, and diverse Canadian Chinese cultural norms related to tobacco use. CONCLUSIONS The findings have implications for the development of future smoking cessation interventions targeting Chinese Canadian immigrant smokers as well as smokers in China.

Abstract
INTRODUCTION The association of respiratory problems with chemical emissions from common indoor materials has been studied but the specific effect of domestic paint has not been widely investigated. The aim of this review is to provide a comprehensive evaluation of experimental, occupational and epidemiological studies that examine the adverse respiratory effects of exposure to domestic paints. METHODS A literature search of PubMed together with consultation with an expert resulted in 997 articles published up to May 2011 of which 3 experimental, 4 occupational and 13 epidemiological studies met selection criteria and were included in the review. RESULTS The occupational literature suggested that work as a (non-spray) painter increases the risk of asthma, but it provides little insight to the risks of painting in the domestic setting. All epidemiological studies, except one, reported associations with some asthma-like symptoms. In children at least there was evidence that painting was associated with wheezing, but the study designs and the exposure assessment were unsuitable to differentiate between acute and longer terms affects. We found the epidemiological evidence to be weak and certainly insufficient to infer causality. CONCLUSION The variable quality of the exposure assignment and heterogeneous study design makes it difficult to draw firm conclusions on whether domestic paint exposures cause or exacerbate asthma in children and/or adults.

Abstract
BACKGROUND A substantial proportion of the world's population is exposed to indoor dampness-related exposures. Since the 1990s, studies have assessed the relation between indoor dampness and mold and rhinitis, but the evidence has been inconclusive. No previous meta-analysis has been reported on this topic. OBJECTIVE We conducted a systematic review and meta-analysis of studies on the relations between indoor dampness and mold and the risk of different types of rhinitis and investigated whether these relations differ according to the type of exposure. METHODS A systematic search of the Ovid MEDLINE and EMBASE databases was conducted (1950 through August 2012), and reference lists of relevant articles were reviewed. Cross-sectional, case-control, and cohort studies in children or adults were selected according to a priori criteria and evaluated by 3 authors independently. RESULTS Thirty-one studies on rhinitis, allergic rhinitis (AR), or rhinoconjunctivitis were included. In meta-analyses the largest risk was observed in relation to mold odor (rhinitis: 2.18 [95% CI, 1.76-2.71]; AR: 1.87 [95% CI, 0.95-3.68]). The risk related to visible mold was also consistently increased (rhinitis: 1.82 [95% CI, 1.56-2.12]; AR: 1.51 [95% CI, 1.39-1.64]; rhinoconjunctivitis: 1.66 [95% CI, 1.27-2.18]). In addition, exposure to dampness was related to increased risk of all types of rhinitis. CONCLUSION This meta-analysis provides new evidence that dampness and molds at home are determinants of rhinitis and its subcategories. The associations were strongest with mold odor, suggesting the importance of microbial causal agents. Our results provide evidence that justifies prevention and remediation of indoor dampness and mold problems, and such actions are likely to reduce rhinitis.

Abstract
Multigenerational co-residence is a widespread phenomenon in China but there is little knowledge about the impact of power dynamics on smoking behaviors among extended family residents. Using a gender lens, this ethnographic study explored how young mothers in extended families in mainland China managed the smoking of their husbands and other family members. Analysis of data resulted in a model of 'two units-three domains' to reflect gendered relationships between young mothers and other family members, and young mothers' participation in family management. Exploration of the mothers' efforts to deal with household smoking using the model provided an explanation for why the young mothers had limited control over household space and could only impose partial restrictions on home smoking in the extended family.

Abstract
CONTEXT AND OBJECTIVE Knowledge of the profile of allergen sensitization among children is important for planning preventive measures. The objective of this study was to assess the prevalence and profile of sensitization to inhaled allergens and food among children and adolescents in an outpatient population in the city of Palmas. DESIGN AND SETTING Cross-sectional study at outpatient clinics in Palmas, Tocantins, Brazil. METHODS Ninety-four patients aged 1-15 years who were attending two pediatric outpatient clinics were selected between September and November 2008. All of the subjects underwent clinical interviews and skin prick tests. RESULTS A positive skin prick test was observed in 76.6% of the participants (72.3% for inhalants and 28.9% for food allergens). The most frequent allergens were Dermatophagoides pteronyssinus (34%), cat epithelium (28.7%), dog epithelium (21.3%), Dermatophagoides farinae (19.1%), Blomia tropicalis (18.1%), cow's milk (9.6%) and grasses (9.6%). A positive skin prick test correlated with a history of atopic disease (odds ratio, OR = 5.833; P = 0.002), a family history of atopic disease (OR = 8.400; P < 0.001), maternal asthma (OR = 8.077; P = 0.048), pet exposure (OR = 3.600; P = 0.012) and cesarean delivery (OR = 3.367; P = 0.019). CONCLUSION Dermatophagoides pteronyssinus was the most frequent aeroallergen and cow's milk was the most prevalent food allergen. There was a positive correlation between a positive skin prick test and several factors, such as a family history of atopic disease, maternal asthma, pet exposure and cesarean delivery.

Abstract
AIMS A cross-sectional study was carried out with the objective of identifying nutrition habits and housing conditions as risk factors for respiratory problems in schoolchildren in Lisbon. MATERIAL AND METHODS Between October and December 2008, parents of 900 students of the basic schools of Lisbon were invited to answer a questionnaire of the International Study of Asthma and Allergies in Childhood Program (ISAAC). The response rate was 40%. Logistic regression was used in the analysis of results. RESULTS The prevalence of asthma, allergic rhinitis and wheeze was 5.6%, 43.0% and 43.3%, respectively. Risk factors independently associated with asthma were wheezing attacks, and dry cough at night not related to common cold in the last 12 months. Wheezing crises were found to affect children daily activities. Risk factors for wheeze were hay fever and the presence of a pet at home. A risk factor for rhinitis was cough at night. The frequent consumption of egg was also associated with increased risk of rhinitis. CONCLUSION Contrarily to asthma, the prevalence of allergic rhinitis and wheeze increased in comparison with previous ISAAC studies. Wheezing attacks were associated with asthma and hay fever was identified as a risk factor of manifesting wheezing symptoms. Having pets at home was pointed out as a significant risk factor for rhinitis, but not smoking exposure, mould, plush toys, diet (except egg consumption), breastfeeding or other conditions.

Abstract
BACKGROUND Experimental data suggest that asthma exacerbation by allergens is enhanced by exposure to environmental tobacco smoke (ETS); however, there is little supporting epidemiologic evidence. To our knowledge, few studies have assessed respiratory symptoms and allergies in this context. OBJECTIVES To evaluate whether the association of exposure to animals (indicators of allergen and endotoxin exposure) with asthma-related symptoms is modified by ETS exposure in Chinese children. METHODS A cross-sectional study of 8,819 children in kindergarten was conducted in 25 districts in northern China. Information on respiratory health and exposure to indoor allergens was obtained using a standard questionnaire from the American Thoracic Society. RESULTS Among the children with ETS exposure in utero, the effects of exposure to animals were significant with respect to persistent cough [adjusted odds ratio (OR) 1.83; 95% confidence interval (CI) 1.12-2.99] and persistent phlegm (adjusted OR 2.40; 95% CI 1.28-4.54). The combined effect of in utero ETS exposure and animal exposure on doctor-diagnosed asthma was approximately as expected on the basis of their independent effects on an additive scale. There was no interaction between animal exposure and ETS exposure in the first 2 years of life or current ETS exposure. CONCLUSIONS This study provides evidence that animal and ETS exposure increases the risk of asthma-related symptoms in children in kindergarten. ETS exposure in utero did modify the effect of animal exposure on persistent phlegm and persistent cough but not on doctor-diagnosed asthma among children.

Abstract
AIMS AND OBJECTIVES To evaluate the effectiveness of a nurse-led patient-centred asthma education programme on home environmental control behaviours of parents of children with moderate or severe asthma. BACKGROUND Reducing allergic triggers is important self-management behaviour for preventing asthma attacks and patient-centred asthma education has been shown to effectively manage chronic disease. DESIGN A preliminary quasi-experimental, non-equivalent control group design was used. METHOD Dyads (n = 75) of parents and their children with moderate or severe asthma (ages 6-14 years) were purposively recruited from the asthma clinics of two hospitals in central Taiwan. The experimental group of 38 children/parents from one hospital received patient-centred asthma education. The comparison group of 37 children/parents from the other hospital received routine individual education. At pretest and at the end of the three-month patient-centred asthma education programme, we measured parents' control of home environmental triggers, children's asthma signs/symptoms and children's pulmonary function. Data were analysed by the general linear model for repeat measures. RESULTS The level of improvement in dust and cleaning methods was significantly greater among parents in the experimental group than among those in the comparison group (p < 0.05). Children with moderate or severe asthma in the experimental group had fewer signs/symptoms of asthma and better lung function than children in the comparison group. CONCLUSIONS Our patient-centred asthma education programme improved parents' home environmental control and children's asthma sign/symptoms and lung function. RELEVANCE TO CLINICAL PRACTICE Nurses can play primary roles as patient educators in asthma clinics. Well-trained patient educators can continuously monitor self-management behaviours to improve patients' compliance with home environmental control, thus leading to better physical outcomes in children with asthma than routine individual asthma education alone.

[PMID: 20211496 DOI: 10.1016/j.ijporl.2010.02.008] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2009] [Revised: 02/08/2010] [Accepted: 02/10/2010] [Indexed: 11/29/2022]
Abstract
OBJECTIVE There is growing evidence that the prevalence of allergic diseases is increasing, especially among children. The aim of this study was to evaluate the incidence and risk factors of allergic rhinitis in 6-12-year-old schoolchildren in Budapest. METHODS A total of 6335 children aged between 6 and 12 years attending 21 randomly selected primary schools in Budapest were surveyed in September 2007 by using a questionnaire consisting in part of questions compiled by the International Study of Asthma and Allergies in Childhood and in part of questions based on our own experience. RESULTS 3933 of the questionnaires (1976 M/1957 F) were appropriately completed by the parents. The prevalence of current allergic rhinitis was 14.9% (n=530), that of physician-diagnosed allergic rhinitis was 11.6% (n=413), and that of cumulative allergic rhinitis was 26.5% (n=943). Male gender (p<0.001), family history of atopy (p<0.001), eczema (p<0.001), urticaria (p<0.001), itchy-watery eyes (p<0.001), coughing (p<0.001), wheezing (p<0.001), a hearing impairment (p<0.001), itching of the palate (p<0.001), frequent upper airway infection (p<0.001), frequent rhinosinusitis (p<0.001), a history of tonsillectomy (p<0.01), a history of adenoidectomy (p<0.001), antibiotics given in the first year of life (p<0.001), paracetamol given in the first year of life (p<0.001), living in a green area (p<0.001), the consumption of soft drinks containing preservatives or colourants (p<0.04), feather bedding (p<0.01), living in a house made of concrete (p<0.001), living not far from an air-polluting factory or mine (p<0.001), and long-lasting disease before the appearance of the allergy (p<0.001) were all significant factors involving an increased risk of allergic rhinitis symptoms. The frequent consumption of tomatoes, nuts, margarine and butter significantly affected the cumulative allergic rhinitis prevalence. RESULTS Overall, the 12-month prevalence of allergic rhinitis in these 6-12-year-old children in Budapest was 14.9%, which is higher than reported from other European countries. Our findings differ from those on other cohorts in that exposure to ragweed and to indoor environmental factors in concrete housing estates in Budapest may be of particular importance as concerns allergic sensitization.
