The aim of this study was to verify smoking cessation rates and associated factors. The study was performed in Greater Metropolitan Belo Horizonte and the town of Bambuí, both in the State of Minas Gerais, Brazil. Study participants included 13,261 and 1,018 adults (> 20 years), respectively, randomly selected among residents of each area. The smoking cessation rate was 40.6% (95%CI: 39.1-42.3) in Greater Metropolitan Belo Horizonte and 38.8% (95%CI: 34.4-43.1) in Bambuí. In Greater Metropolitan Belo Horizonte, smoking cessation showed an independent and positive association with age (> 40 years), schooling (4-7 and > 8 years), number of chronic conditions (> 2), and number of medical visits in the previous year (1-3 and > 4), and a negative association with marital status (unmarried). Bambuí showed an independent and positive association with age (> 40 years) and a negative association with number of hospitalizations in the previous year (> 2). The heterogeneity of factors associated with smoking cessation made it difficult to identify vulnerable groups in order to target prevention strategies. Further research is important to elucidate this heterogeneity.
本研究的目的是核实戒烟率及相关因素。该研究在巴西米纳斯吉拉斯州的大贝洛奥里藏特市和班布伊镇开展。研究参与者分别为从每个地区居民中随机选取的13261名和1018名成年人（>20岁）。大贝洛奥里藏特市的戒烟率为40.6%（95%置信区间：39.1 - 42.3），班布伊镇的戒烟率为38.8%（95%置信区间：34.4 - 43.1）。在大贝洛奥里藏特市，戒烟与年龄（>40岁）、受教育程度（4 - 7年和>8年）、慢性病数量（>2种）以及上一年的就诊次数（1 - 3次和>4次）呈独立正相关，与婚姻状况（未婚）呈负相关。班布伊镇则显示戒烟与年龄（>40岁）呈独立正相关，与上一年的住院次数（>2次）呈负相关。与戒烟相关的因素存在异质性，这使得难以确定弱势群体以制定针对性的预防策略。进一步的研究对于阐明这种异质性很重要。
