To study the association between BMI and lifestyle factors such as alcohol consumption, smoking habits, education level and marital status in a Spanish graduate population.
Cross-sectional analysis of 8,706 participants (3,643 men and 5,063 women) from the Seguimiento Universidad de Navarra (SUN) Study, an ongoing dynamic cohort study in Spain. Data on body weight, height and sociodemographic characteristics, and lifestyle habits were collected with self-administered validated questionnaires.
Among older participants (above sex-specific median age), educational level was a factor independently associated with BMI. University graduates with a lower educational level (3-year college degree or 5-year university degree) had a significantly higher BMI than those with doctorate which requires, at least, 8 years of university studies in Spain. Mean BMI was significantly higher among past smokers than among never smokers. Alcohol consumption, marital and smoking status were associated with BMI only among men.
In a study whose members were all university graduates, several factors were independently associated with a higher BMI, such as less years of higher education, past smoking, marital status and higher alcohol consumption.
研究 BMI 与生活方式因素（如饮酒、吸烟习惯、教育水平和婚姻状况）在西班牙研究生人群中的相关性。
对西班牙纳瓦拉大学随访研究（SUN）中 8706 名参与者（3643 名男性和 5063 名女性）进行横断面分析。使用自我管理的经过验证的问卷收集体重、身高和社会人口特征以及生活方式习惯的数据。
在年龄较大的参与者（高于性别特异性中位数年龄）中，教育水平是与 BMI 独立相关的因素。与博士学位（至少需要 8 年的西班牙大学学习）相比，具有较低教育水平（3 年制大学学位或 5 年制大学学位）的大学毕业生 BMI 明显更高。过去吸烟者的平均 BMI 明显高于从不吸烟者。在男性中，饮酒、婚姻状况和吸烟状况仅与 BMI 相关。
在一项研究成员均为大学毕业生的研究中，一些因素与更高的 BMI 独立相关，例如接受高等教育的年限较少、过去吸烟、婚姻状况和更高的饮酒量。
