In epidemiology, environmental diseases are diseases that can be directly attributed to environmental factors (as distinct from genetic factors or infection). Apart from the true monogenic genetic disorders , which are rare, environment is a major determinant of the development of disease.
Environmental epidemiology research can inform government policy change, risk management activities, and development of environmental standards. Vulnerability is the summation of all risk and protective factors that ultimately determine whether an individual or subpopulation experiences adverse health outcomes when an exposure to an ...
The contrast between residents of rural and suburban areas can be seen in a study of Kenya [43] and Ethiopia, [44] where prevalence of asthma is lower in rural areas, and higher in urban areas. A similar trend can be seen in the United States, where an urban-rural gradient shows the increase in the prevalence of asthma closer to the inner city ...
This can be achieved by drawing a random sample from the original population at risk. This has as a consequence that the control group can contain people with the disease under study when the disease has a high attack rate in a population. [citation needed]
Thunderstorm asthma (also referred to in the media as thunder fever or a pollen bomb [1]) is the triggering of an asthma attack by environmental conditions directly caused by a local thunderstorm. Due to the acute nature of the onset and wide exposure of local populations to the same triggering conditions, severe epidemic thunderstorm asthma ...
Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
Although clinically debated, [6] [7] the Dutch hypothesis remains one of four main plausible explanations which could help explain the complex pathogenesis of COPD, others being the protease-antiprotease hypothesis (involving alpha 1-antitrypsin overexpression and consequent alpha-1 proteinase deficiency), the British hypothesis (regarding a ...
Asthma is a respiratory disease that can begin or worsen due to exposure at work and is characterized by episodic narrowing of respiratory airways. Occupational asthma has a variety of causes, including sensitization to a specific substance, causing an allergic response; or a reaction to an irritant that is inhaled in the workplace. Exposure to ...
