目的 了解乡镇成年居民饮水量特征及其影响因素,对乡镇居民饮水行为提出建议。方法 以重庆市某地两个乡镇常住居民作为调查对象。通过现场逐一问卷调查及体检,获得个人饮水量以及饮水相关的生理、社会、行为等信息。采用t检验、方差分析、χ^2检验、多元Logistic回归分析比较不同特征人群的饮水量及其影响因素的关联性。结果 共调查5 493人（男性2 067人,女性3 426人）,平均年龄58.76岁。总人群日饮水量（1.50±0.75）L,男性饮水量显著高于女性[（1.61±0.81）L vs（1.44±0.70）L,P〈0.05]。单因素分析结果显示超重、已婚、较高文化程度、较高经济收入、吸烟、饮酒、饮茶、不能按时吃饭、劳动强度大、日常坚持锻炼、睡眠质量好的人群饮水量较高（P〈0.05）。多元Logistic回归分析发现：性别、BMI、年收入、饮酒、饮茶、日常锻炼是饮水量的相关因素（P〈0.05）。结论重庆某地乡镇成年居民日均饮水量总体偏低,日均饮水量未达到中国营养学会推荐的男性1.7 L、女性1.5 L标准。与饮水量显著相关的影响因素较为复杂,建议在保证饮水安全的基础上,鼓励居民主动足量喝水。

英文摘要：

Objective To investigate the characteristics of water consumption and its influencing factors among town adult residents, in order to bring forward suggestions on water consumption behaviors for township residents. Methods Residents living in 2 towns of Chongqing were recruited as the research subjects. Questionnaire and physical examination were adopted to obtain their personal water consumption and water-related physical, social and behavioral data. Student＇ s t test, One-Way ANOVA, Chi-square and multivariate logistic regression analyses were used to analyze the association of the daily water consumption with its influencing factors. Results There were 5 493 subjects （2 067 males and 3 426 females） in this study, with an average age of 58.76 years. The total daily water consumption was 1.50 ＋ 0.75 L for each person, with that of men significantly higher than that of women （ 1.61 ＋--0.81 vs 1.44 ＋0.70 L, P 〈0.05 ）. Single factor results showed that those of overweight, being married, higher educational level, higher income, smoking, alcohol consumption, tea consumption, having meals not on time, higher labor intensity, more daily exercise, and better sleep quality had significantly higher water consumption （ P 〈 0.05 ）. Multivariate logistic regression analysis found that gender, body mass index （BMI）, annual income, alcohol consumption, tea consumption and daily exercise were related factors affecting the water consumption （ P 〈 0.05 ）. Conclusion The daily water consumption is comparatively low in the adult residents living in the towns of Chongqing, and the daily water consumption does not meet the standards of 1.7 L for men and 1. 5 L for women recommended by Chinese nutrition society. The influencing factors associated with water consumption are relatively complex. We suggest that after guaranteeing the safety of drinking water, residents shall be encouraged to drink enough water actively.
