Results from research conducted on the association between cannabis use and body mass index (BMI) reveal mixed findings. It is possible that individual differences in decision-making (DM) abilities may influence these associations.
This study analyzed how amount of cannabis use, DM performance, and the interaction of these variables influenced BMI and clinical classifications of weight among adolescents (ages 14 to 18 years; 56% male; 77% Hispanic). The sample consisted primarily of cannabis users (n=238) without a history of significant developmental disorders, birth complications, neurological conditions, or history of mood, thought, or attention deficit/hyperactivity disorder at screening. Furthermore, few participants engaged frequently in other drug use (except for alcohol and nicotine).
Analyses revealed that more lifetime cannabis use was associated with a higher BMI and greater likelihood of being overweight/obese. Interactions between DM and cannabis use on BMI were not significant, and DM was not directly associated with BMI.
Our findings suggest that among adolescents, cannabis use is associated with a greater BMI regardless of DM abilities and this association is not accounted for by other potential factors, including depression, alcohol use, nicotine use, race, ethnicity, or IQ. (JINS, 2016, 22, 944-949).
关于大麻使用与体重指数（BMI）之间关联的研究结果显示出不一致的发现。决策（DM）能力的个体差异可能会影响这些关联。
本研究分析了大麻使用量、DM表现以及这些变量的相互作用如何影响青少年（14至18岁；56%为男性；77%为西班牙裔）的BMI和体重临床分类。样本主要由大麻使用者（n = 238）组成，这些使用者在筛查时没有显著发育障碍、出生并发症、神经疾病或情绪、思维或注意力缺陷/多动障碍病史。此外，很少有参与者经常使用其他药物（酒精和尼古丁除外）。
分析显示，终生使用大麻较多与较高的BMI以及超重/肥胖的可能性较大有关。DM与大麻使用对BMI的相互作用不显著，且DM与BMI无直接关联。
我们的研究结果表明，在青少年中，无论DM能力如何，大麻使用都与较高的BMI有关，且这种关联不受其他潜在因素影响，包括抑郁、酒精使用、尼古丁使用、种族、民族或智商。（《青少年神经心理学杂志》，2016年，第22卷，第944 - 949页）
