Several studies have suggested a positive effect of occasional cannabis consumption on the frequency of leisure-time physical activity, possibly due to more motivation before, more enjoyment during, and better recovery after engaging in leisure-time physical exercise. While such an effect would contradict the stereotypical image of lower physical activity levels in cannabis users as compared to non-users, evidence has been mixed at best. The current study investigated this proposed association in a representative sample of the Belgian population.
Data from four waves of the Belgian Health Interview Survey (HIS; repeated cross-sectional survey; 2001 - 2018) were used in a regression and propensity matching analysis to examine the association between past-month cannabis use and physical activity levels, while controlling for potentially confounding variables. A total of n = 19,936 individuals (48.9% female) aged 15-64 years were included in the analysis. We modelled physical activity in function of past-month cannabis use while adjusting for potential confounders.
Both the regression analysis and the propensity-matching analysis revealed no evidence in favor of a positive effect of past-month cannabis use on physical activity level (estimated OR = 0.97, 95% CI = [0.74, 1.28] and estimated RR = 0.90, 95% CI = [0.70; 1.16] respectively). Descriptive analyses of baseline characteristics suggested some clear differences between users and non-users that were in line with previous studies.
There was no evidence suggesting that past-month cannabis users have better or worse physical activity levels compared to non-users in the Belgian population aged 15-64 years.
多项研究表明，偶尔吸食大麻对休闲时间身体活动频率有积极影响，这可能是由于在进行休闲体育锻炼前更有动力、锻炼期间更享受以及锻炼后恢复得更好。虽然这种影响与大麻使用者与非使用者相比身体活动水平较低的刻板印象相矛盾，但证据充其量也只是参差不齐。本研究在比利时人口的代表性样本中调查了这一假设的关联。
使用来自比利时健康访谈调查（HIS；重复横断面调查；2001 - 2018年）四轮的数据进行回归和倾向匹配分析，以检验过去一个月大麻使用与身体活动水平之间的关联，同时控制潜在的混杂变量。分析共纳入了19,936名年龄在15 - 64岁之间的个体（48.9%为女性）。我们在调整潜在混杂因素的同时，根据过去一个月大麻使用情况对身体活动进行建模。
回归分析和倾向匹配分析均未发现证据支持过去一个月大麻使用对身体活动水平有积极影响（估计比值比=0.97，95%置信区间=[0.74, 1.28]；估计风险比=0.90，95%置信区间=[0.70; 1.16]）。基线特征的描述性分析表明，使用者和非使用者之间存在一些明显差异，这与先前的研究一致。
没有证据表明，在15 - 64岁的比利时人群中，过去一个月吸食大麻的使用者与非使用者相比，其身体活动水平更好或更差。
