Changes in lifestyles and in the environment over the last decades are probably the most important cause of the overweight epidemic, but the findings are inconsistent among studies. The purpose of this study was to investigate the association of several socio-economic and lifestyle factors with overweight in Flemish adults, using BMI > or = 25 kg/m2, waist circumference (WC) > or = 94 cm (men) or > or = 80 cm (women) and the combination of BMI and WC for identifying overweight.
This cross-sectional epidemiological study was conducted by the Flemish Policy Research Centre Sport, Physical Activity and Health between October 2002 and February 2004 in 46 Flemish communities. A total of 4903 Flemish adults (2595 men and 2308 women), aged 18 to 75 years, from a population-based random sample were included in the analysis. Body weight, height and WC were measured, and socio-economic and lifestyle factors were reported by means of validated questionnaires.
The results of the logistic regressions revealed that age is positively associated with overweight in both genders. Alcohol consumption is associated with overweight only in men. Men smoking in the past and watching TV >11 h/week have significantly higher OR's for overweight, while men who participate in health related sports >4 h/week have significantly lower OR's for overweight. In women, watching TV >9 h/week was positively associated with overweight. Women who are current smokers or participate in health related sports >2.5 h/week or with a higher educational level have significantly lower odds for overweight. Different results are observed between the first (BMI) and the second model (WC) in both genders. In men, the models differ for education and health related sports, while in women they differ for smoking status and leisure time physical activity.
The present study confirms the contention that overweight is a multifactorial problem. Age and TV viewing are positively associated with overweight, while educational level and health related sports are negatively related to overweight in both genders. In men, alcohol consumption and smoking in the past are also among the lifestyle factors associated with overweight. This study also indicates that BMI and WC do not have the same discriminative function regarding different lifestyle factors.
过去几十年生活方式和环境的变化可能是超重流行的最重要原因，但研究结果并不一致。本研究的目的是使用体重指数（BMI）≥25kg/m²、腰围（WC）≥94cm（男性）或≥80cm（女性）以及BMI和WC的组合来确定超重，调查佛兰德成年人中几种社会经济和生活方式因素与超重之间的关联。
这项横断面流行病学研究由佛兰德体育、身体活动与健康政策研究中心于2002年10月至2004年2月在46个佛兰德社区进行。分析纳入了来自基于人群的随机样本的4903名佛兰德成年人（2595名男性和2308名女性），年龄在18至75岁之间。测量了体重、身高和腰围，并通过经过验证的问卷报告了社会经济和生活方式因素。
逻辑回归结果显示，年龄与男女超重均呈正相关。饮酒仅与男性超重有关。过去吸烟且每周看电视>11小时的男性超重的比值比（OR）显著更高，而每周参加与健康相关运动>4小时的男性超重的OR显著更低。在女性中，每周看电视>9小时与超重呈正相关。目前吸烟或每周参加与健康相关运动>2.5小时或教育水平较高的女性超重的几率显著更低。在男女中，第一种模型（BMI）和第二种模型（WC）之间观察到不同的结果。在男性中，模型在教育和与健康相关的运动方面存在差异，而在女性中，模型在吸烟状况和休闲时间身体活动方面存在差异。
本研究证实了超重是一个多因素问题的观点。年龄和看电视与超重呈正相关，而教育水平和与健康相关的运动在男女中均与超重呈负相关。在男性中，饮酒和过去吸烟也是与超重相关的生活方式因素。本研究还表明，BMI和WC在区分不同生活方式因素方面没有相同的功能。
