Which risk factor is confirmed through measurements at two different occasions?

Hypertension is identified as a risk factor that requires confirmation through measurements taken at two different occasions. This process is important because single measurements can be influenced by various factors such as stress, time of day, and even recent physical activity. Consistent readings help ensure that the individual genuinely has elevated blood pressure, providing a basis for diagnosis and necessary intervention.

In the context of the other options, dyslipidemia typically involves assessing lipid levels through blood tests at a single point in time, while a sedentary lifestyle is often evaluated through surveys or self-reports rather than direct measurements over time. Pre-diabetes can also be diagnosed with a single blood glucose measurement, though follow-up may be recommended for confirmation. However, hypertension stands out in requiring multiple readings to accurately assess the condition.
