Dust weight and asthma prevalence in the National Survey of Lead and Allergens in Housing (NSLAH).

ABSTRACT:

Background

Settled dust has been used in studies to assess exposures to allergens and other biologically active components, but it has not been considered in the aggregate in relation to respiratory health outcomes in the general population.

Objective

We addressed whether total house dust weight, an index of total dust exposure, was associated with respiratory health outcomes in the National Survey of Lead and Allergens in Housing (1998-1999) (NSLAH).

Methods

NSLAH was a cross-sectional survey designed to represent permanently occupied housing units in the United States. In each household, a questionnaire was administered and settled dust was vacuumed from five locations. Linear regression models were used to identify predictors of dust weight; logistic regression models were used to examine the relationship between dust weight and asthma and wheeze.

Results

Dust weight samples were available for 829 households, and survey information was available for 2,456 participants (children and adults). Lower income, older homes, household pets, having a smoker in the house, and less frequent cleaning predicted higher dust weight levels in U.S. households. Higher levels of dust weight were associated with greater odds of current asthma and wheeze. The strongest associations were seen for wheeze [adjusted odds ratio (OR) = 1.99; 95% confidence interval (CI), 1.21-3.28 for bedroom bed dust; OR = 2.81; 95% CI, 1.52-5.21 for upholstery dust). These associations persisted when adjusting for allergen and endotoxin exposures.

Conclusions

Dust weight, an index of total dust exposure in the home, may contribute to respiratory outcomes independently of the exposure to specific components.

Project description:PurposeEstimating the prevalence and severity of asthma symptoms with standardized methods of population-based surveys is a critical step in reducing asthma burden. However, no sufficient surveys have been conducted in most countries of the Middle East especially at the national level. In this survey, we applied sound measures to estimate the prevalence and severity of asthma symptoms and related risk factors in adults in Saudi Arabia.Patients and methodsIn this national cross-sectional study, the prevalence and severity of asthma symptoms were estimated throughout the country. Overall, 7955 adult individuals were selected from 20 regions across Saudi Arabia through their children at schools using a multistage, stratified cluster-sampling technique. A validated questionnaire, including the core and environmental questions of the Global Asthma Network questionnaires, was applied from March 4 to April 25, 2019. In addition, multivariate logistic regression analysis was performed to investigate the independent relationships between current wheeze and related risk factors.ResultsThe overall prevalence of current wheeze (wheeze during the past 12 months) was 14.2%. Among persons with current wheeze, 38.1% were affected by severe asthma symptoms. Although a high percentage of those who had experienced asthma-ever reported that their asthma was diagnosed by doctors (83.3%), only 38.4% had a written plan for controlling their asthma. Women were more likely to develop current wheeze (adjusted odds ratio (aOR) 1.4; 95% CI: 1.1-1.7), while other statistically significant factors associated with current wheeze were jobs (aOR 11.8; 95% CI: 7.3-18.9), current exposure to moisture or damp spots (aOR 2.2; 95% CI: 1.5-3.4), heating the house when it is cold (aOR 1.7; 95% CI: 1.3-2.1), and ever using tobacco daily (aOR 2.7; 95% CI: 2.0-3.5).ConclusionsThese findings provide enough evidence for health authorities in Saudi Arabia about the prevalence and severity of asthma symptoms, asthma control, and associated risk factors to scale up monitoring projects, control plans, and high-impact interventions.
