Abstract
OBJECTIVES To analyze the prevalence and Years Lived with Disability of Asthma in children under 5 years old and the time trends in Sichuan Southwest China from 1990-2019. METHODS Based on the results of the Global Burden of Disease Study 2019 (GBD2019), we present the time trend, sex specific prevalence, Years Lived with Disability (YLDs) and deaths due to asthma under 5 years old in Sichuan and compared them with national indicators in the same period. RESULTS The number of children under 5 years old with asthma decreased overall from 1990 to 2007 and increased overall from 2008 to 2019. The time trend of prevalence rate was similar. In 2019, over 111 thousands children under 5 years old suffered from asthma, the prevalence rate was 2,584 per 100 thousand, YLDs was 4.5 thousands, and YLDs rate was 105 per 100 thousand in Sichuan. Compared with 1990, the number of patients decreased by 48.6%, the prevalence increased by 9.4%, the YLDs decreased by 48.9%, and the YLDs rate increased by 9.7% in 2019. The increase in the prevalence and YLDs rate of asthma children in Sichuan was higher than the national overall, but the number of asthma deaths and deaths rate in Sichuan and the whole nation all decreased. CONCLUSIONS The results in Sichuan Southwest China show the prevalence and YLDs of asthma children under 5 years old increased over the past 30 years, and were higher than the overall increase in China. Male children are the key population of increasing asthma disease burden and deserves more attention. More targeted prevention and control measures are still needed to reduce the incidence of asthma.

Glob Health Res Policy 2021; 6:17. [PMID: 34039445 PMCID: PMC8157798 DOI: 10.1186/s41256-021-00199-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2020] [Accepted: 05/04/2021] [Indexed: 12/03/2022] Open
Abstract
Background Asthma disproportionately affects minority and low-income children. We examined asthma prevalence, management and outcomes, focusing on race/ethnicity and acculturation of parents (particularly English language proficiency). Methods This cross-sectional, correlational analysis used a de-identified population-based survey, the California Health Interview Survey, for years 2001–2015. Survey-weighted analysis with SAS 9.4 was used to determine asthma prevalence among children 1 to 11 years of age. Descriptive analysis was conducted, adjusting for survey design and combination of multiple years of data. The Pearson test, using design-based F values was used to determine statistically significant differences between those having/not having a doctor diagnosis of asthma. Multivariable logistic regression, with jackknife approach to obtain confidence intervals, was used to examine associations of child and parental characteristics with asthma prevalence, management, and outcomes. Results The 61,625 completed surveys represented an estimated annual population of 5.7 million children, of which 12.9 % had asthma. There were significant (p < 0.001) differences by age, gender, race, and language proficiency, with higher asthma prevalence for children 6 to 11 years of age (15.5 %), males (15.3 %), African Americans (19.5 %), and parents speaking English very well (14.1 %). Compared to children whose parents spoke English very well, those whose parents spoke English not well or not at all were less likely to achieve optimal asthma management, i.e. to have received a management plan from doctor (OR 0.30; 95 % Confidence Interval 0.20–0.46)), to be currently taking medication to control asthma (OR 0.52; 95 % CI 0.36–0.74)), or to be not confident in ability to control asthma (OR 3.10; 95 % CI 1.49–6.42). Children whose parents spoke English fairly well rather than very well had worse outcomes, i.e. were more likely to have an emergency room visit in past 12 months (OR 1.92; 95 % CI 1.03–3.61) and were more likely to miss school due to asthma in past 12 months (OR 0.71; 1.01–2.94). Conclusions Socio-demographics had a limited role in explaining differences across a handful of asthma management and outcome measures in California. Parental English language proficiency had the most consistent influence, underscoring the need for culturally and linguistically competent care.

Abstract
In the present study, the effects of albiflorin (ALB) on the pulmonary inflammation induced by ovalbumin (OVA) in an asthmatic mouse model were investigated. Airway hyperreactivity (AHR) in asthmatic mice was detected using the acetylcholine stimulation test. Eosinophilia cells in the serum of asthmatic mice were counted. Hematoxylin and eosin (H&E) staining was used to observe pathological changes in lung tissue. Inflammatory cytokines, including interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α were detected in bronchoalveolar lavage fluid (BALF) and lung tissue using enzyme-linked immunosorbent assay (ELISA). Western blotting was used to detect the mitogen-activated protein kinase/nuclear factor kappa B (MAPK/NF-κB) signaling pathway in the lungs of asthmatic mice. The results from the present study indicated that ALB dramatically suppressed the expression of inflammatory cytokines including IL-1β, IL-6, and TNF-α, and inflammatory cells. In addition, ALB significantly decreased malondialdehyde (MDA) content as well as increased superoxide dismutase (SOD) activity. ALB also alleviated AHR in asthmatic mice and improved pathological changes in the lungs. In addition, ALB inhibited the MAPK/NF-κB signaling pathway in the lungs of the asthmatic mice. Thus, ALB appears to inhibit lung inflammation in asthmatic mice via regulation of the MAPK/NF-κB signaling pathway.

Review of the effect of air pollution exposure from industrial point sources on asthma-related effects in childhood. Environ Epidemiol 2019; 3:e077. [PMID: 33778345 PMCID: PMC7939412 DOI: 10.1097/ee9.0000000000000077] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Accepted: 10/10/2019] [Indexed: 01/01/2023] Open
Abstract
We reviewed epidemiologic studies of the association between exposure to air pollution from industries and asthma-related outcomes in childhood. We searched bibliographic databases and reference lists of relevant articles to identify studies examining the association between children's exposure to air pollution from industrial point-sources and asthma-related outcomes, including asthma, asthma-like symptoms, wheezing, and bronchiolitis. We extracted key characteristics of each study and when appropriate we performed a random-effects meta-analysis of results and quantified heterogeneity (I 2). Thirty-six studies were included in this review. Meta-analysis was generally not possible and limited to a few studies because of substantial variation across design characteristics and methodologies. In case-crossover studies using administrative health data, pooled odds ratio (OR) of hospitalization for asthma and bronchiolitis in children <5 years were 1.02 [95% confidence intervals (CI): 0.96, 1.08; I 2 = 56%] and 1.01 (95% CI: 0.97, 1.05; I 2 = 64%) per 10 ppb increase in the daily mean and hourly maximum concentration of sulfur dioxide (SO2), respectively. For PM2.5, pooled ORs were 1.02 (95% CI: 0.93, 1.10; I 2 = 56%) and 1.01 (95% CI: 0.98, 1.03 I 2 = 33%) per 10 μg/m3 increment in the daily mean and hourly maximum concentration. In cross-sectional studies using questionnaires, pooled ORs for the prevalence of asthma and wheezing in relation to residential proximity to industry were 1.98 (95% CI: 0.87, 3.09; I 2 =71%) and 1.33 (95% CI: 0.86, 1.79; I 2= 65%), respectively. In conclusion, this review showed substantial heterogeneity across study designs and methods. Meta-analysis results suggested no evidence of an association for short-term asthma-related effects and an indication for long-term effects, but heterogeneity between results and limitations in terms of design and exposure assessment preclude drawing definite conclusions. Further well-conducted studies making use of a longitudinal design and of refined exposure assessment methods are needed to improve risk estimates.

Abstract
Objective: The objective of the study was to determine the prevalence and associated risk factors of asthma in Aboriginal adolescents in Canada based on the Canadian Aboriginal Peoples Survey (APS) 2012. Few studies have investigated the prevalence and risk factors of asthma in Aboriginal adolescents in Canada. Methods: Data from the cross-sectional APS 2012 were analyzed to accomplish the objective. Logistic regression analysis was utilized to determine significant risk factors of lifetime diagnosis of asthma among Aboriginal adolescents. The outcome of interest for adolescents was based on the question: "Do you have asthma that have been diagnosed by a health professional?" Individual, environmental, and contextual factors were tested for an association with lifetime diagnosis of asthma among adolescents. Results: The overall prevalence of lifetime diagnosis of asthma was 16.0%. The prevalence of lifetime diagnosis of asthma was 16.8% for adolescent boys and 15.3% for adolescent girls. Based on multivariable logistic regression analysis, the risk factors of lifetime diagnosis of asthma were: age, income, being overweight, smoking inside the home, having one to two children under 18 years in the household, history of bronchitis, living in an urban residence, education, and geographical location. Female sex was reported to have a protective effect on or reduce risk of the prevalence of lifetime diagnosis of asthma compared to the male sex. Conclusions: Lifetime diagnosis of asthma prevalence appears to be lower in Aboriginal adolescent girls than in adolescent boys. Lifetime diagnosis of asthma prevalence in these adolescents is associated with age, income, education, being overweight, smoking inside the home, history of bronchitis, and location of residence, both geographical region and urban residence. The prevalence of lifetime diagnosis of asthma among Aboriginal adolescent is higher compared to the general adolescent population in Canada.

Abstract
BACKGROUND Lifestyles profoundly determine the quality of an individual's health and life since his childhood. Many diseases in adulthood are avoidable if health-risk behaviors are identified and improved at an early stage of life. The aim of the present research was to characterize a cohort of children aged 6-8 years selected in order to perform an epidemiological molecular study (the MAPEC_LIFE study), investigate lifestyles of the children that could have effect on their health status, and assess possible association between lifestyles and socio-cultural factors. METHODS A questionnaire composed of 148 questions was administered in two different seasons to parents of children attending 18 primary schools in five Italian cities (Torino, Brescia, Pisa, Perugia and Lecce) to obtain information regarding the criteria for exclusion from the study, demographic, anthropometric and health information on the children, as well as some aspects on their lifestyles and parental characteristics. The results were analyzed in order to assess the frequency of specific conditions among the different seasons and cities and the association between lifestyles and socio-economic factors. RESULTS The final cohort was composed of 1,164 children (50.9 boys, 95.4% born in Italy). Frequency of some factors appeared different in terms of the survey season (physical activity in the open air, the ways of cooking certain foods) and among the various cities (parents' level of education and rate of employment, sport, traffic near the home, type of heating, exposure to passive smoking, ways of cooking certain foods). Exposure to passive smoking and cooking fumes, obesity, residence in areas with heavy traffic, frequency of outdoor play and consumption of barbecued and fried foods were higher among children living in families with low educational and/or occupational level while children doing sports and consuming toasted bread were more frequent in families with high socio-economic level. CONCLUSIONS The socio-economic level seems to affect the lifestyles of children enrolled in the study including those that could cause health effects. Many factors are linked to the geographical area and may depend on environmental, cultural and social aspects of the city of residence.

Abstract
CONTEXT AND OBJECTIVE: The impact of the port of Santos, Brazil, on the population's health is unknown. We aimed to evaluate the association between living near the port area and physical inactivity and sedentary behavior. DESIGN AND SETTING: Cross-sectional study developed at a university laboratory and a diagnostic clinic. METHODS: 553 healthy adults were selected and their level of physical activity in daily life was assessed using accelerometers. Multiple linear and logistic regressions were performed using physical inactivity and sedentary behavior as the outcomes and living near the port area as the main risk factor, with adjustments for the main confounders. RESULTS: Among all the participants, 15% were resident near the port area. They took 699 steps/day and presented, weekly, 2.4% more sedentary physical activity, 2.0% less time in standing position and 0.9% more time lying down than residents of other regions. Additionally, living near the port area increased the risk of physical inactivity by 2.50 times and the risk of higher amounts of sedentary behavior (≥ 10 hours/day) by 1.32 times. CONCLUSION: Living near the port of Santos is associated with physical inactivity and higher sedentary behavior among adults, regardless of confounders. The reasons for this association should be investigated in longitudinal studies.

Abstract
BACKGROUND The prevalence of allergic diseases is increasing. We evaluated temporal trends in the prevalence of asthma, rhinitis and eczema in adolescents (13-14 years) living in Taubaté, SP, Brazil (2005-2012) and assessed the relationship between these prevalences and the residential proximity to Presidente Dutra Highway (PDH, a heavily travelled highway). METHODS This cross-sectional study of adolescents (N=1039) from public and private schools was evaluated using the standard questionnaire of the International Study of Asthma and Allergies in Childhood (ISAAC) plus a question about their place of residence in relation to PDH. The data obtained were compared to the 2005 data using a chi-square test or Fisher's exact test. An analysis by groups consisting of two phases (two-step cluster) was used to evaluate the effect of living near PDH. RESULTS There was a lifetime increase in the prevalence of active asthma (15.3% vs. 20.4%, p=0.005) and physician-diagnosed asthma (6.8% vs. 9.2%, p=0.06) and a decrease in the symptoms of active rhinitis (36.6% vs. 18.5%) between 2005 and 2012. A high frequency of asthma and rhinitis (18.1% vs. 23.2%, respectively) was observed among adolescents living close or very close to PDH; furthermore, 85.6% of the adolescents without symptoms of asthma or rhinitis lived far from PDH. CONCLUSION An increase in the prevalence of asthma and a decrease in the prevalence of rhinitis were observed during the studied period. Living near PDH was associated with higher rates of asthma, rhinitis, and eczema.

Abstract
Purpose This study aimed to examine the separate effects of maternal and paternal history on the onset of asthma in children and evaluate the relationship between age of asthma onset in parents and risk of asthma in their children. Methods We used data from the third National Health and Nutrition Examination Survey. We developed new continuous standardized scores for survey data to quantify parental history that incorporated both the occurrence of asthma and the age at onset, and associated these scores with asthma risk in the children. The association analysis was adjusted for sex and obesity status. Results Children with maternal history have elevated asthma risk (hazard ratio of 3.71, 95% CI: 1.19–11.60) than those without, and those whose mothers had earlier age of onset have increased risk of asthma compared to those whose mothers had later age of onset. On the contrary, paternal history had a relatively smaller effect that may be only detectable in larger samples (hazard ratio of 2.17, 95% CI: 0.69–6.79). Conclusion Maternal asthma history was strongly associated with the onset of asthma in the second generation, and children whose mother had an earlier age of onset had an increased risk of 3.71. For an approximately 10-year decrease in mother’s age at onset of asthma, the risk of asthma for the offspring increased by 1.37-fold. Using our new risk scores led to smaller standard errors and thus more precise estimates than using a binary indicator.
