Vaccines to prevent or limit disease (influenza has decreased substantially) Diabetics able to live relatively normal lives if diabetes is controlled. Issue: contaminated water is the only source for approximately 50% of the developing (cid:449)orld"s populatio(cid:374) Findings: pathogenic microorganisms are killed by heat and uv exposure. Application: solar decontamination; water bottles filled with contaminated water are placed on metal roofs for approximately 8 hours to make the water safe for consumption. Exposure of hypertension can lead to heart disease. Outcome of heart disease can lead to heart attack, stroke, and increased mortality rates. Methods used to provide credible and valid research. Phases of health research: formulating a hypothesis, epidemiologic observation to reinforce hypothesis, test the hypothesis in formal studies, intervention to alter outcome and preserve health. Primary: identify risk factors to determine likelihood of developing disease.
