A pilot survey of men aged 35 and over in Buenos Aires indicated that many had one or more risk factors for chronic diseases. A low response rate hampered the investigation: on average it proved necessary to visit several homes in order to obtain one interview. Furthermore, at the cost of US$ 10 incurred per interview, large prospective investigations would be precluded in most developing countries, but case-control studies assessing tobacco use and other risk factors retrospectively would be a good alternative.
对布宜诺斯艾利斯35岁及以上男性进行的一项初步调查表明，许多人有一个或多个慢性病风险因素。低回应率阻碍了调查：平均而言，为了获得一次访谈，有必要走访多户人家。此外，每次访谈花费10美元，大多数发展中国家将无法开展大规模前瞻性调查，但回顾性评估烟草使用及其他风险因素的病例对照研究将是一个不错的选择。
