Question

BlackTom AI · Accepted Answer

Environmental health encompasses how environmental factors influence human health and disease risk. Option 1, 'Health related to non-genetic risk factors,' is partly true but too narrow, since environmental health covers more than non-genetic risks and includes exposures and conditions in the environment that affect health. Option 2, 'Environmental characteristics,' is vague and incomplete, describing what the environment is like rather than how it impacts health outcomes. Option 4, 'Health related to geological phenomena,' targets a subset of environmental aspects and misses the broader scope that includes air, water, chemical exposures, housing, occupational factors, and public health infrastructure. Option 3, 'The prevention of disease, disability, and death related to exposure to environmental conditions,' aligns with the core aim of environmental health by focusing on how exposures to environmental conditions lead to adverse health outcomes and, importantly, how those outcomes can be prevented through interventions, policy, and public health measures. This framing integrates risk assessment, exposure pathways, susceptibility, and preventive actions, which are central to environmental health practice. In summary, the most comprehensive statement is the one that links disease prevention to environmental exposures and conditions, rather than merely describing environmental features or isolated risk factors. Recognizing the preventive aim also captures the field's emphasis on reducing harm through environmental controls, regulations, and health-promoting actions. While the first option mentions non-genetic risk factors, it does not explicitly connect those risks to disease prevention or exposures, making it less complete. The second option’s vagueness prevents it from conveying the health impact, and the fourth option narrows the scope to geological phenomena, excluding other critical environmental determinants. Thus, the reasoning points toward option 3 as the most representative description of environmental health as a discipline focused on preventing health problems arising from environmental exposures.
