For this set of questions, the interviewer must read out a series of symptoms and determine if the respondent had any of those symptoms in the last 12 months. The point of asking symptom-related questions is to screen those individuals who might have a specific health condition or disease. Because there could be a number of symptoms that characterise a given health condition, and because some symptoms may be common to different conditions, it is important that the interviewer probe for each symptom to see whether the respondent may have an active disease. It is also important that the time period for the symptoms (in the last 12 months) be clearly understood by the respondent and not confused with other time frames used in this section (such as "ever" and "the last 2 weeks").
During the last 12 months, have you experienced pain or discomfort in your chest when you walk uphill or hurry?

Chest pain is the most frequent symptom of angina. It usually occurs during an increased physical activity (such as walking uphill, stairs, carrying heavy things, etc) when body needs more active blood circulation. This pain is referred to as “exertional” pain. Many patients do not have pain if they are resting or performing very mild physical activity. Such pain may be described in a number of different ways, such as a squeezing pain, squeezing pressure, tightness, ache or heaviness in the chest. The interviewer should probe with local terms to make sure to capture all unpleasant sensations that the respondent may have. If the respondent responds he/she never hurries or walks uphill (because of poor mobility or any other reason), then record “Never walks uphill or hurries”.
