Raised ambient temperatures may result in a negative energy balance characterized by decreased food intake and raised energy expenditure. This study tested whether indoor temperatures above the thermoneutral zone for clothed humans (∼23 °C) were associated with a reduced body mass index (BMI).
Participants were 100,152 adults (≥16 years) drawn from 13 consecutive annual waves of the nationally representative Health Survey for England (1995-2007).
BMI levels of those residing in air temperatures above 23 °C were lower than those living in an ambient temperature of under 19 °C (b = -0.233, SE = 0.053, P < 0.001), in analyses that adjusted for participant age, gender, social class, health and the month/year of assessment. Robustness tests showed that high indoor temperatures were associated with reduced BMI levels in winter and non-winter months and early (1995-2000) and later (2001-2007) survey waves. Including additional demographic, environmental, and health behavior variables did not diminish the link between high indoor temperatures and reduced BMI.
Elevated ambient indoor temperatures are associated with low BMI levels. Further research is needed to establish the potential causal nature of this relationship.
环境温度升高可能导致负能量平衡，表现为食物摄入减少和能量消耗增加。本研究旨在检验人体着装的舒适温度区（约 23°C）以上的室内温度是否与较低的体重指数（BMI）有关。
研究对象为来自英国连续 13 年健康调查（1995-2007 年）的 100152 名成年人（≥16 岁）。
在调整了参与者的年龄、性别、社会阶层、健康状况和评估月份/年份后，分析表明，居住在环境温度高于 23°C 的人群的 BMI 水平低于居住在环境温度低于 19°C 的人群（b=-0.233，SE=0.053，P<0.001）。稳健性测试表明，室内高温与冬季和非冬季月份以及早期（1995-2000 年）和后期（2001-2007 年）调查波次的 BMI 水平降低有关。纳入更多的人口统计学、环境和健康行为变量并没有削弱室内高温与 BMI 降低之间的联系。
环境室内温度升高与较低的 BMI 水平有关。需要进一步研究以确定这种关系的潜在因果性质。
