We analyzed lung function and asthma impairment and risk among nonobese children with asthma, comparing those who were obese in young adulthood with those who remained nonobese. We carried out the post hoc analysis of 771 subjects with mild to moderate asthma who were not obese (pediatric definition, body mass index [BMI] < 95th percentile) when enrolled in the Childhood Asthma Management Program at ages 5-12 years. The subjects were then followed to age 20 years or more. For visits at ages 20 years or more, spirometry values as percent predicted and recent asthma symptom scores and prednisone exposure were compared between 579 subjects who were nonobese at all visits and 151 who were obese (adult definition of BMI ≥ 30 kg/m(2)) on at least 1 visit (median number of visits when obese = 4, IQR 2-7). Compared with participants who were nonobese (BMI 23.4 ± 2.6 kg/m(2)), those who became obese (BMI 31.5 ± 3.8 kg/m(2)) had significant decreases in forced expiratory volume in the first second (FEV1)/forced vital capacity (FVC) (P < .0003) and FEV1 (P = .001), without differences in FVC (P = .15) during visits at ages 20 years or more. For each unit increase of BMI, FEV1 percent predicted decreased by 0.29 (P = .0009). The relationship between BMI and lung function was not confounded by sex or BMI at baseline. Asthma impairment (symptom scores) and risk (prednisone use) did not differ between the 2 groups. Becoming obese in early adulthood was associated with increased airway obstruction, without impact on asthma impairment or risk.

The objectives of the study were to estimate the prevalence of asthma in Miami-Dade County (MDC) schoolchildren to aid case-finding and linkage to care. We used the CDC Youth Risk Behavior Surveillance System (YRBSS) definition of possible asthma ("Ever told by a doctor or nurse that they had asthma and still had asthma") and analyzed data from four sources. These included the: (1)-MDC YRBSS 2009, (2)-MDC Health Connect Asthma Survey of school nurses (>2008), (3)-parents' survey in the five HealthConnect survey elementary schools with highest asthma prevalence, and (4)-focus group with parents of asthmatic children. (1)-MDC YRBSS data showed that 21.3% of high- and 21.4% of middle-school students had been diagnosed with possible asthma. Prevalence was the highest in African-American middle-school girls (26.9%). (2)-HealthConnect survey responders reported that 4.9% of the students in 131 MDC schools had possible asthma. Asthma prevalence was higher in elementary schools (median = 7.1%) and in low-income MDC zip codes. (3)-Of the parent survey responders, 24.9% indicated that their child had possible asthma, and 19.2% reported that their children had no usual source of care. (4)-Focus group participants reported frequent loss of Medicaid coverage for their children, landlords' indifference to the role of poorly maintained housing in asthma, and unmet needs regarding knowledge of health system navigation. Asthma may be common in MDC schoolchildren, particularly in poor communities. Formidable structural factors limit the caregivers' abilities to manage childhood asthma.

Prematurity is a risk factor for asthma, and certain ethnic or racial minorities such as Puerto Ricans and non-Hispanic blacks are disproportionately affected by both prematurity and asthma. In this review, we examine current evidence to support maternal psychosocial stress as a putative link between prematurity and asthma, while also focusing on disruption of the hypothalamic-pituitary-adrenal (HPA) axis and immune responses as potential underlying mechanisms for stress-induced "premature asthma." Prenatal stress may cause not only abnormalities in the HPA axis but also epigenetic changes in the fetal glucocorticoid receptor gene (NR3C1), leading to impaired glucocorticoid metabolism. Moreover, maternal stress can alter fetal cytokine balance, favoring TH2 (allergic) immune responses characteristic of atopic asthma: interleukin 6 (IL-6), which has been associated with premature labor, can promote TH2 responses by stimulating production of IL-4 and IL-13. Given a link among stress, prematurity, and asthma, future research should include birth cohorts aimed at confirming and better characterizing "premature asthma." If confirmed, clinical trials of prenatal maternal stress reduction would be warranted to reduce the burden of these common comorbidities. While awaiting the results of such studies, sound policies to prevent domestic and community violence (eg, from firearms) are justified, not only by public safety but also by growing evidence of detrimental effects of violence-induced stress on psychiatric and somatic health.

To examine the association between depressive symptoms and asthma or BDR in US adults. Cross-sectional study of 20,272 adults aged 20 to 79 years from the 2007-2012 National Health and Nutrition Examination Survey. Depressive symptoms were measured using the 9-item Patient Health Questionnaire, and classified as none to minimal, mild, moderate, moderately severe, and severe. Major depression (comprising moderately severe to severe symptoms) was defined as a 9-item Patient Health Questionnaire score of 15 or more. Anxiety was defined as 5 or more days feeling anxious in the previous month. Current asthma was defined as having been diagnosed with asthma by a doctor or health professional and 1 or more asthma attack in the previous year. BDR (as percentage of baseline FEV1) was measured in 1356 participants with FEV1/forced vital capacity of less than ...

We examined whether folate deficiency is associated with number of positive skin tests to allergens or severe asthma exacerbations in a high-risk population, and further assessed whether such association is explained or modified by vitamin D status. Cross-sectional study of 582 children aged 6 to 14 years with (n=304) and without (n=278) asthma in San Juan, Puerto Rico. Folate deficiency was defined as a plasma folate ≤20 ng/ml. Our outcomes were the number of positive skin tests to allergens (range=0-15) in all children, and (in children with asthma) ≥1 severe exacerbation in the previous year. Logistic and negative binomial regression models were used for the multivariate analysis. All multivariate models were adjusted for age, gender, household income, residential proximity to a major road and (for atopy) case/control status; those for severe exacerbations were also adjusted for use of inhaled corticosteroids and vitamin D insufficiency (a plasma 25(OH)D <30ng/ml). In a multivariate analysis, folate deficiency was significantly associated with an increased degree of atopy and 2.2 times increased odds of ≥1 severe asthma exacerbation (95% confidence interval [CI] for odds ratio [OR]=1.1-4.6). Compared with children who had normal levels of both folate and vitamin D, those with both folate deficiency and vitamin D insufficiency had nearly eightfold increased odds of ≥1 severe asthma exacerbation (95% CI for adjusted OR=2.7-21.6). Folate deficiency is associated with increased degree of atopy and severe asthma exacerbations in school-aged Puerto Ricans. Vitamin D insufficiency may further increase detrimental effects of folate deficiency on severe asthma exacerbations.

Regional variation in asthma prevalence is likely multifactorial and due to genetics, perinatal exposures, diet, obesity, tobacco use, indoor and outdoor pollutants, psychosocial stress and microbial or parasitic infections. Similarly, non-uniform progress in asthma management leads to regional variability in disease morbidity. Future studies of distinct asthma phenotypes should follow-up well-characterised Latin American subgroups and examine risk factors that are unique or common in Latin America (eg, stress and violence, parasitic infections and use of biomass fuels for cooking). Because most Latin American countries share the same barriers to asthma management, concerted and multifaceted public health and research efforts are needed, including approaches to curtail tobacco use, campaigns to improve asthma treatment, broadening access to care and clinical trials of non-pharmacological interventions (eg, replacing biomass fuels with gas or electric stoves).

We examined whether exposure to gun violence is associated with asthma in children, particularly in those reporting fear of leaving their home. Case-control study of 466 children aged 9-14 years with (n = 234) and without (n = 232) asthma in San Juan, Puerto Rico. Lifetime exposure to gun violence was defined as hearing a gunshot more than once. We also assessed whether the child was afraid to leave his/her home because of violence. Asthma was defined as physician-diagnosed asthma and wheeze in the prior year. We used logistic regression for the statistical analysis. All multivariate models were adjusted for age, gender, household income, parental asthma, environmental tobacco smoke, prematurity and residential distance from a major road. Cases were more likely to have heard a gunshot more than once than control subjects (n = 156 or 67.2% vs. n = 122 or 52.1%, P < 0.01). In a multivariate analysis, hearing a gunshot more than once was associated with asthma (odds ratio [OR] = 1.8, 95% confidence interval [CI] = 1.1-1.7, P = 0.01). Compared with children who had heard a gunshot not more than once and were not afraid to leave their home because of violence, those who had heard a gunshot more than once and were afraid to leave their home due to violence had 3.2 times greater odds of asthma (95% CI for OR = 2.2-4.4, P < 0.01). Exposure to gun violence is associated with asthma in Puerto Rican children, particularly in those afraid to leave their home. Stress from such violence may contribute to the high burden of asthma in Puerto Ricans.

We aimed to examine the association among obesity, insulin sensitivity, MS, and lung function in US adolescents with and without asthma. We performed a cross-sectional study of 1429 adolescents aged 12 to 17 years in the 2007-2010 National Health and Nutrition Examination Survey. Adjusted regression was used to assess the relationships among obesity, insulin sensitivity/resistance, MS, and lung function in children with and without asthma. Insulin resistance was negatively associated with FEV1 and forced vital capacity (FVC) in adolescents with and without asthma, whereas MS was associated with lower FEV1/FVC ratios, with a more pronounced decrease found among asthmatic patients; these associations were driven by overweight/obese adolescents. Higher body mass index was associated with a decrease in FEV1/FVC ratios among adolescents with insulin resistance. Compared with healthy participants, adolescents with MS had an approximately 2% decrease in FEV1/FVC ratios, adolescents with asthma had an approximately 6% decrease, and those with MS and asthma had approximately 10% decreased FEV1/FVC ratios (P < .05). Insulin resistance and MS are associated with worsened lung function in overweight/obese adolescents. Asthma and MS synergistically decrease lung function, as do obesity and insulin resistance. These factors might contribute to the pathogenesis of asthma severity in obese patients and warrant further investigation.

Cross-sectional study of 582 children aged 6 to 14 years with (n=304) and without (n=278) asthma in San Juan, Puerto Rico. Folate deficiency was defined as a plasma folate ≤20 ng/ml. Our outcomes were the number of positive skin tests to allergens (range=0-15) in all children, and (in children with asthma) ≥1 severe exacerbation in the previous year. Logistic and negative binomial regression models were used for the multivariate analysis.

In a multivariate analysis, folate deficiency was significantly associated with an increased degree of atopy and 2.2 times increased odds of ≥1 severe asthma exacerbation (95% confidence interval [CI] for odds ratio [OR]=1.1-4.6). Compared with children who had normal levels of both folate and vitamin D, those with both folate deficiency and vitamin D insufficiency had nearly eightfold increased odds of ≥1 severe asthma exacerbation (95% CI for adjusted OR=2.7-21.6). Folate deficiency is associated with increased degree of atopy and severe asthma exacerbations in school-aged Puerto Ricans. Vitamin D insufficiency may further increase detrimental effects of folate deficiency on severe asthma exacerbations.

Regional variation in asthma prevalence is likely multifactorial and due to genetics, perinatal exposures, diet, obesity, tobacco use, indoor and outdoor pollutants, psychosocial stress and microbial or parasitic infections. Similarly, non-uniform progress in asthma management leads to regional variability in disease morbidity. Future studies of distinct asthma phenotypes should follow-up well-characterised Latin American subgroups and examine risk factors that are unique or common in Latin America (eg, stress and violence, parasitic infections and use of biomass fuels for cooking). Because most Latin American countries share the same barriers to asthma management, concerted and multifaceted public health and research efforts are needed, including approaches to curtail tobacco use, campaigns to improve asthma treatment, broadening access to care and clinical trials of non-pharmacological interventions (eg, replacing biomass fuels with gas or electric stoves).

We aimed to examine the association among obesity, insulin sensitivity, MS, and lung function in US adolescents with and without asthma. We performed a cross-sectional study of 1429 adolescents aged 12 to 17 years in the 2007-2010 National Health and Nutrition Examination Survey. Adjusted regression was used to assess the relationships among obesity, insulin sensitivity/resistance, MS, and lung function in children with and without asthma. Insulin resistance was negatively associated with FEV1 and forced vital capacity (FVC) in adolescents with and without asthma, whereas MS was associated with lower FEV1/FVC ratios, with a more pronounced decrease found among asthmatic patients; these associations were driven by overweight/obese adolescents. Higher body mass index was associated with a decrease in FEV1/FVC ratios among adolescents with insulin resistance. Compared with healthy participants, adolescents with MS had an approximately 2% decrease in FEV1/FVC ratios, adolescents with asthma had an approximately 6% decrease, and those with MS and asthma had approximately 10% decreased FEV1/FVC ratios (P < .05). Insulin resistance and MS are associated with worsened lung function in overweight/obese adolescents. Asthma and MS synergistically decrease lung function, as do obesity and insulin resistance. These factors might contribute to the pathogenesis of asthma severity in obese patients and warrant further investigation.
