摘要
目的探索在外就餐频率与超重肥胖的关系。方法采用多阶段分层随机抽样的方法,在6个项目省12个区县中,按照大、中、小餐馆规模,每个项目点随机选取16家中餐馆,每个餐馆随机访问20名18-65岁就餐者(男女各半)进行问卷调查,了解就餐者的基本信息、在外就餐情况,并记录自报近期的身高、体重等信息。根据成人BMI分类标准,BMI≥24.0判定为超重肥胖。采用多项Logistic回归法分析在外就餐频率和超重肥胖的关系。结果共纳入3312名调查对象,49.76%的就餐者过去1个月每周在外就餐超过1次,就餐者超重肥胖的比例为33.27%。控制了年龄、文化程度、家庭收入、家庭人数、职业和婚姻状况后,与过去1个月无在外就餐者相比,男性每周在外就餐3d及以上时,超重肥胖的风险是前者的1.553倍;女性在外就餐的频率为每周不超过1次、每周1~2 d和每周3 d及以上时,超重肥胖的风险分别是前者的1.849倍、1.603倍和2.229倍;差异均有统计学意义。结论在外就餐增大了女性超重肥胖的风险,男性仅在高频率在外就餐时与超重肥胖存在正相关。
Objective To explore the association between the frequencies of eating out and overweight/obesity.Methods Multi-stage stratified random sampling method was adopted.In 12 districts of 6 Provinces,according to the scale of restaurants(large,medium and small),16 Chinese restaurants were randomly selected from each district,and then 20 dinners aged 18-65-year-old in each restaurant were randomly visited and conducted a questionnaire survey,which included the basic information,the frequencies of eating out,and the self-reported recent height and weight were collected.According to the adult BMI classification standard,BMI≥24.0 was used as cut-off value for overweight/obese.Multiple Logistic regression method was used to analyze the association.Results Totally,3312 respondents were included,and 49.76%of them had eating out more than once a week in the last month,and 33.27%of them were overweight/obese.After controlled by age,education,family income,family size,occupation and marital status,the risk of being overweight/obese among the male dinners who had ate out 3 days or more per week was 1.553 times compared with participants who had no eating out in the last month.When the frequencies of eating out were≤1/week,1-2 days/week or≥3 days/week,the risks of overweight/obesity among female dinners were 1.849 times,1.603 times and 2.229 times compared with participants who had no eating out in the last month.The differences were of statistical significance.Conclusion Eating out may increase the risk of being overweight/obese among female dinners,only high frequency of eating out had positive correlation with overweight/obesity among male dinners.
