    大规模人工智能(AI)语言模型聊天机器人,聊天生成预培训变压器(ChatGPT),以其快速有效地提供数据的能力而闻名。本研究旨在评估ChatGPT对麻醉程序的医学反应。
    两位麻醉师作者选择了30个问题,代表患者可能对手术和麻醉的询问。这些问题被输入到英语的ChatGPT的两个版本中。然后,总共31名麻醉师评估了每个反应的质量,数量,和总体评估,使用5点Likert量表.描述性统计数据总结了分数,配对样本t检验比较ChatGPT3.5和4.0。
    关于质量,“适当”是ChatGPT3.5和4.0的最常见评级(40%和48%,分别)。对于数量,在3.5的病例中,59%的病例被认为是“不足”,在4.0的病例中,69%被认为是“足够”。在总体评估中,3分最常见的是3.5分(36%),而4分占主导地位的是4.0(42%)。平均质量分数为3.40和3.73,平均数量分数为-0.31(不足和适当之间)和0.03(适当和过度之间),分别。3.5的平均总分为3.21,4.0的平均总分为3.67。从4.0开始的反应显示在三个方面有统计学上的显着改善。
    ChatGPT产生的反应大多从适当到略显不足,提供总体平均信息量。4.0版本的性能优于3.5版本,需要进一步的研究来研究AI聊天机器人在帮助患者获得医疗信息方面的潜在效用。
    UNASSIGNED: The large-scale artificial intelligence (AI) language model chatbot, Chat Generative Pre-Trained Transformer (ChatGPT), is renowned for its ability to provide data quickly and efficiently. This study aimed to assess the medical responses of ChatGPT regarding anesthetic procedures.
    UNASSIGNED: Two anesthesiologist authors selected 30 questions representing inquiries patients might have about surgery and anesthesia. These questions were inputted into two versions of ChatGPT in English. A total of 31 anesthesiologists then evaluated each response for quality, quantity, and overall assessment, using 5-point Likert scales. Descriptive statistics summarized the scores, and a paired sample t-test compared ChatGPT 3.5 and 4.0.
    UNASSIGNED: Regarding quality, \"appropriate\" was the most common rating for both ChatGPT 3.5 and 4.0 (40 and 48%, respectively). For quantity, responses were deemed \"insufficient\" in 59% of cases for 3.5, and \"adequate\" in 69% for 4.0. In overall assessment, 3 points were most common for 3.5 (36%), while 4 points were predominant for 4.0 (42%). Mean quality scores were 3.40 and 3.73, and mean quantity scores were - 0.31 (between insufficient and adequate) and 0.03 (between adequate and excessive), respectively. The mean overall score was 3.21 for 3.5 and 3.67 for 4.0. Responses from 4.0 showed statistically significant improvement in three areas.
    UNASSIGNED: ChatGPT generated responses mostly ranging from appropriate to slightly insufficient, providing an overall average amount of information. Version 4.0 outperformed 3.5, and further research is warranted to investigate the potential utility of AI chatbots in assisting patients with medical information.

    The school age period is characterized by significant physical and intellectual growth, necessitating the monitoring of macronutrient intake and its impact on weight and height. The objective of this study is to investigate the association between the quality and quantity of protein and fat consumption with anthropometric indices in primary school girls in Kerman. This cross-sectional analysis was conducted on primary school girls aged 6-12 (n 330) from ten schools in Kerman, Iran. A validated and reliable dish-based 185-item food frequency questionnaire was used. We calculated the amount of proteins and fats as the percentage of daily calories and grams per day. Plant-based and animal-based proteins were used to assess the protein quality. To assess the fat quality, we considered trans fatty acids (TFA), cholesterol, vegetable oils, solid vegetable oils, animal oils, omega-6 Polyunsaturated fatty acids (PUFAs), omega-3 PUFA, and (PUFAs + Monounsaturated fatty acids (MUFAs))/Saturated fatty acids (SFAs), PUFAs/SFA, and (MUFA + PUFA)/(SFA + TFA). There was a significant positive association between height-for-age z-score (HAZ) and plant protein (p < 0.001) and vegetable oils (p = 0.038) after adjustment. In higher tertiles of animal protein, weight-for-age z-score (WAZ) (p = 0.024) were significantly higher. A significant positive association was observed between omega-3 PUFA and mid-upper arm circumference (MUAC) (p = 0.039) and BMI-for-age z-score (BAZ) (p = 0.016). Our study emphasizes the importance of monitoring protein and fat intake in primary school girls for optimal growth. Positive associations were found between plant-based protein, vegetable oils and HAZ, as well as animal protein and WAZ, highlighting the impact of protein quality on growth indicators.

    膳食补充剂的使用在美国成年人中很常见。我们的目的是调查数量,持续时间,坚持,以及服用补充剂的个人使用补充剂的原因。分析了2011年至2018年国家健康与营养检查调查(NHANES)数据集的数据。合并四个周期的数据来估计这些结果。结果以总体组和亚组表示。所有分析均加权为具有全国代表性。泰勒级数线性化方法用于生成方差估计。共有12529名参与者参加。超过70%的这些人报告每天服用超过一个单位的膳食补充剂。值得注意的是,约40%的人服用补充剂超过5年,约67%的人高度坚持至少一种补充剂.然而,只有26.9%的补品是按照医生的建议服用的.膳食补充剂摄入的主要原因包括改善整体健康状况(37.2%),保持健康(34.7%),骨骼健康(21.4%),和饮食补充(20.3%)。我们的研究结果表明,大多数参与者主动使用多种膳食补充剂,专注于自我管理的健康和预防,大量致力于长期使用和高度坚持。医疗保健专业人员应在指导此类行为方面发挥更积极的作用,以优化美国各地膳食补充剂使用者的健康结果。
    Dietary supplement use is common among US adults. We aimed to investigate the quantity, duration, adherence, and reasons for supplement use in individuals who take supplements. Data from 2011 to 2018 from the National Health and Nutrition Examination Survey (NHANES) dataset were analyzed. Four cycles of data were combined to estimate these outcomes. Results are presented as overall group and by subgroups. All analyses were weighted to be nationally representative. The Taylor Series Linearization approach was used to generate variance estimates. A total of 12,529 participants were included. Over 70% of these individuals reported taking more than one unit of dietary supplements daily. Notably, approximately 40% had been taking supplements for more than five years and about 67% were highly adherent to at least one supplement. However, only 26.9% of these supplements were taken following a doctor\'s recommendation. The primary reasons for dietary supplements intake included improving overall health (37.2%), maintaining health (34.7%), bone health (21.4%), and diet supplementation (20.3%). Our findings indicate that most participants proactively used multiple dietary supplements focused on self-managed health and prevention, with substantial dedication to long-term use and high adherence. Healthcare professionals should play a more active role in guiding such behaviors to optimize the health outcomes of dietary supplement users across the United States.

    如果马赛克的瓷砖对称排列,那么这些图块构成的图像也必须是对称的。本文阐述并捍卫了在这种情况下工作的一般原则:对称性不能以不对称性为基础。有人认为,该原则支持对四种形而上学观点的强烈反对:关系主义,时间的紧张或“B”理论,和比较主义。对这些反对意见提出了回应,呼吁碎片主义,认为现实包含彼此不相容的事实。但是碎片主义可能被认为太奇怪而不能容忍,如果是的话,那么本文提出的反对意见很可能是致命的。
    If the tiles of a mosaic are arranged symmetrically, then the image those tiles constitute must be symmetric as well. This paper formulates and defends the general principle at work in this case: roughly, that a symmetry cannot ground an asymmetry. It is argued that the principle supports strong objections to four metaphysical views: qualitativism, relationalism, the tenseless or \'B\' theory of time, and comparativism. A response to these objections is developed which appeals to fragmentalism, the view that reality contains facts which are incompatible with one another. But fragmentalism might be thought too bizarre to tolerate, and if it is, then the objections developed in this paper may well be fatal.

    背景:学龄是身体和认知成长的关键时期,这需要评估饮食摄入量及其对体重和身高的影响。这项研究旨在确定克尔曼市小学女生碳水化合物摄入的质量和数量与选定的人体测量指标之间的关系,伊朗。
    方法:这项横断面研究是对Kerman的330名6-12岁的小学女生进行的。我们使用了经过验证和可靠的基于菜肴的185项食物频率问卷来评估人们的食物摄入量。我们评估了儿童饮食中碳水化合物的含量,即每天卡路里和克数的百分比。我们使用膳食纤维摄入量(克/天),血糖负荷,全谷物与总谷物的比例,和固体碳水化合物与总碳水化合物的比例,以评估碳水化合物的质量。高度,体重,和手臂周长进行了测量。我们通过将以千克为单位的体重除以以厘米为单位的身高来计算体重指数(BMI)。我们使用世界卫生组织的5至19岁女孩的z得分图表来评估年龄BMI(BAZ)的z得分,身高年龄(HAZ),和年龄体重(WAZ)。评估了社会经济状况和身体活动。我们使用ANOVA和ANCOVA统计检验来评估人体测量指标与碳水化合物数量和质量参数之间的关联。
    结果:碳水化合物摄入量最高的参与者的人体测量指数明显更高,包括臂围,BMI年龄z评分(BAZ),身高年龄z评分(HAZ)(分别为p<0.001,p<0.001和p=0.009)。随着血糖负荷(GL)和膳食纤维摄入量的增加,包括臂围在内的人体测量指标(GL:p<0.001,纤维:p<0.001),BAZ(GL:p<0.001,纤维:P<0.001),和HAZ(GL:P=0.009,纤维:p<0.001)显著增加。
    结论:我们得出结论,碳水化合物摄入量与人体测量指标之间存在正相关关系(MUAC,BAZ,和HAZ)。此外,随着血糖负荷和膳食纤维摄入量的增加,包括MUAC在内的人体测量指标,BAZ,HAZ增加。
    BACKGROUND: The school-age is a crucial period of physical and cognitive growth, which requires an assessment of dietary intake and its influence on body weight and height. This study aims to determine the association between the quality and quantity of carbohydrate intake with selected anthropometric indices in primary school girls in Kerman City, Iran.
    METHODS: This cross-sectional study was conducted on 330 primary school girls ages 6-12 years in Kerman. We used a validated and reliable dish-based 185-item food frequency questionnaire to evaluate people\'s food intake. We assessed the amount of carbohydrates in children\'s diets as the percentage of daily calories and grams per day. We used dietary fiber intake (grams/day), the glycemic load, the ratio of whole grain to total grain, and the ratio of solid carbohydrates to total carbohydrates to assess carbohydrate quality. Height, weight, and arm circumference were measured. We calculated body mass index (BMI) by dividing the weight in kilograms by the height in centimeters squared. We used the World Health Organization z-scores charts for girls 5 to 19 years old to assess z-scores for BMI-for-age (BAZ), height-for-age (HAZ), and weight-for-age (WAZ). Socioeconomic status and physical activity were assessed. We used ANOVA and ANCOVA statistical tests to assess the association between anthropometric indices and carbohydrate quantity and quality parameters.
    RESULTS: Participants with the highest amount of carbohydrate intake had significantly higher anthropometric indices, including arm circumference, BMI-for-age z score (BAZ), and Height-for-age z score (HAZ) (p < 0.001, p < 0.001, and p = 0.009, respectively). With the increase in glycemic load (GL) and dietary fiber intake, anthropometric indices including arm circumference (GL: p < 0.001, Fiber: p < 0.001), BAZ (GL: p < 0.001, Fiber: P < 0.001), and HAZ (GL: P = 0.009, Fiber: p < 0.001) increased significantly.
    CONCLUSIONS: We concluded that there was a positive association between the amount of carbohydrate intake and anthropometric indices (MUAC, BAZ, and HAZ). Also, with the increase in glycemic load and dietary fiber intake, the anthropometric indices including MUAC, BAZ, and HAZ increased.

    背景:下颌皮质骨的变化已在患有慢性疾病的儿童中得到证实,但在健康人群中却没有。
    目的:我们旨在使用牙科全景X光片(DPT)对健康儿科人群的下颌皮质骨进行定性和定量评估。次要目的是评估牙齿状态对皮质骨的影响。
    方法:660个人的DPT,6-18岁,由两名盲检人员进行评估。根据下颌皮质指数(MCI)对骨骼进行定性分类,使用下颌皮质宽度指数(MCW)计算其宽度。使用Fisher精确检验性别和年龄之间的差异,并通过卡方检验与牙齿状况的相关性。
    结果:骨形态与性别有显著的相关性,女孩比男孩有更频繁和更尖锐的内缘,显示出半月缺陷的人。侵蚀程度随着年龄的增长而增加,骨骼厚度也是如此。记录了厚度与牙列类型之间的正相关,在混合牙列阶段,正常骨骼占优势。在骨形态或厚度与牙齿状态相关的因素之间发现了NA。
    结论:骨质量和数量在不同性别和年龄组之间差异显著。牙科需求和治疗特征似乎并不影响上述参数。
    BACKGROUND: Changes in mandibular cortical bone have been documented in children with chronic diseases but not in healthy populations.
    OBJECTIVE: We aimed to qualitatively and quantitatively evaluate the mandibular cortical bone of a healthy paediatric population using dental panoramic radiographs (DPTs). The secondary objective was to assess the effect of dental status on cortical bone.
    METHODS: The DPTs of 660 individuals, aged 6-18 years, were evaluated by two blinded examiners. Bone was qualitatively categorized according to the Mandibular Cortical Index (MCI), and its width was calculated using the Mandibular Cortical Width Index (MCW). Differences between gender and age were tested using Fisher\'s exact and correlation with dental status with the chi-square test.
    RESULTS: A significant correlation was observed between bone morphology and gender, with girls having more frequent even and sharp endosteal margins than boys, who showed semilunar defects. The degree of erosion increased with age, as did bone thickness. A positive correlation between thickness and type of dentition was recorded, with normal bone predominating in children in the mixed dentition stage. Νο correlation was found between bone morphology or thickness and the factors associated with dental status.
    CONCLUSIONS: Bone quality and quantity vary significantly between different genders and age groups. Dental needs and treatment characteristics did not seem to affect the above parameters.

    流感疫苗在保护个体免受流感病毒感染和严重疾病的影响方面发挥着至关重要的作用。然而,目前的流感疫苗效果欠佳,在疫苗毒株与循环毒株不匹配的情况下进一步降低。增强流感疫苗功效的一种策略是通过延长抗原递送,从而模拟自然感染的抗原动力学。延长的抗原可用性显示定量增强流感病毒特异性免疫应答,但其如何影响诱导的免疫应答的质量是未知的。因此,本研究旨在调查延长流感疫苗的递送时间是否比初次加强免疫所诱导的免疫应答质量更好.
    给小鼠每日剂量的全灭活流感病毒疫苗,为期14、21或28天;对照组接受间隔28天的初免-加强免疫。
    我们的数据表明,延长28天的抗原递送可诱导最高水平的细胞和体液免疫反应,其次是21天和14天的交货时间,和强化免疫。此外,延长疫苗递送也提高了诱导的抗体反应的质量,高亲合力抗体水平较高,平衡的IgG亚类概况,和更高水平的交叉反应抗体。
    我们的发现有助于更好地了解流感疫苗接种的免疫反应,并对未来缓释流感疫苗的设计和开发具有重要意义。
    Influenza vaccines play a vital role in protecting individuals from influenza virus infection and severe illness. However, current influenza vaccines have suboptimal efficacy, which is further reduced in cases where the vaccine strains do not match the circulating strains. One strategy to enhance the efficacy of influenza vaccines is by extended antigen delivery, thereby mimicking the antigen kinetics of a natural infection. Prolonging antigen availability was shown to quantitatively enhance influenza virus-specific immune responses but how it affects the quality of the induced immune response is unknown. Therefore, the current study aimed to investigate whether prolongation of the delivery of influenza vaccine improves the quality of the induced immune responses over that induced by prime-boost immunization.
    Mice were given daily doses of whole inactivated influenza virus vaccine for periods of 14, 21, or 28 days; the control group received prime-boost immunization with a 28 days interval.
    Our data show that the highest levels of cellular and humoral immune responses were induced by 28 days of extended antigen delivery, followed by 21, and 14 days of delivery, and prime-boost immunization. Moreover, prolonging vaccine delivery also improved the quality of the induced antibody response, as indicated by higher level of high avidity antibodies, a balanced IgG subclass profile, and a higher level of cross-reactive antibodies.
    Our findings contribute to a better understanding of the immune response to influenza vaccination and have important implications for the design and development of future slow-release influenza vaccines.

    背景:研究人员需要准确测量大麻消费量以评估风险和收益。测量大麻花和精矿数量的调查方法仍然不发达。目标:我们检查了测量花和浓缩物数量的“克”和“命中”单位,计算THC(mgTHC)的毫克数。方法:在线调查参与者(n=2,381)报告了首选单位(点击量或克数),每种产品过去一周的点击量和克数,和产品%THC。分位数回归比较了单位偏好亚组之间的mgTHC。基于命中的mgTHC计算假设通用的每命中克数比(GPHR)。为了检查个性化的GPHR,我们测试了“两项方法”,“将总克数除以总点击数,和“一项法”,“将0.5克除以对以下问题的回答:“通过[管理方法]完成1/2克[产品]需要多少总点击量?”结果:参与者主要是日常消费者(77%),50%的女性,平均年龄39.0(SD16.4),85%白色49%全职工作。与那些喜欢点击的人相比,那些喜欢克单位的人报告消耗更多的点击和克,更高的%THC产品,因此,mgTHC中位数较大(花命中mgTHC:32vs.91(95CI:52-67);花克mgTHC:27vs.113(95CI:73-95);集中命中mgTHC:29vs.59(95CI:15-43);浓缩克mgTHC:61vs.129(95CI:43-94))。“两项”和“一项”方法的GPHR相似,通常比通用GPHR大或小50%。结论:允许受访者在报告大麻数量时选择“命中”或“克”不会影响mgTHC的估计。低负担,一项方法产生个性化的“命中大小”,可能会改善mgTHC估计。
    Background: Researchers need accurate measurements of cannabis consumption quantities to assess risks and benefits. Survey methods for measuring cannabis flower and concentrate quantities remain underdeveloped.Objective: We examined \"grams\" and \"hits\" units for measuring flower and concentrate quantities, and calculating milligrams of THC (mgTHC).Methods: Online survey participants (n = 2,381) reported preferred unit (hits or grams), past-week hits and grams for each product, and product %THC. Quantile regression compared mgTHC between unit-preference subgroups. Hits-based mgTHC calculations assumed a universal grams-per-hit ratio (GPHR). To examine individualized GPHRs, we tested a \"two-item approach,\" which divided total grams by total hits, and \"one-item approach,\" which divided 0.5 grams by responses to the question: \"How many total hits would it take you to finish 1/2 g of your [product] by [administration method]?\"Results: Participants were primarily daily consumers (77%), 50% female sex, mean age 39.0 (SD 16.4), 85% White, 49% employed full-time. Compared to those who preferred the hits unit, those who preferred the grams unit reported consuming more hits and grams, higher %THC products, and consequently, larger median mgTHC (flower-hits mgTHC: 32 vs. 91 (95%CI: 52-67); flower-grams mgTHC: 27 vs. 113 (95%CI: 73-95); concentrate-hits mgTHC: 29 vs. 59 (95%CI: 15-43); concentrate-grams mgTHC: 61 vs. 129 (95%CI: 43-94)). \"Two-item\" and \"one-item\" approach GPHRs were similar and frequently 50% larger or smaller than the universal GPHR.Conclusion: Allowing respondents to choose \"hits\" or \"grams\" when reporting cannabis quantities does not compromise mgTHC estimates. A low-burden, one-item approach yields individualized \"hit sizes\" that may improve mgTHC estimates.

    背景:吃零食是一种常见的饮食行为,占日常能量摄入的很大一部分,使其成为饮食质量的关键决定因素。然而,零食频率之间的关系,心脏代谢健康的质量和时间仍不清楚.
    方法:人口学,饮食,在UKPREDICT1队列(N=1002)(NCT03479866)中评估了健康状况(空腹和餐后心脏代谢血液和人体测量标志物)和粪便宏基因组学数据.零食(主餐之间消耗的食物或饮料)在2-4天内自我报告(称重记录)。确定了平均零食频率和质量[零食饮食指数(SDI)](排除后N=854)。零食频率之间的关联,使用回归模型评估心脏代谢血液和人体测量标志物的质量和时间(调整年龄,性别,BMI,教育,身体活动水平和主要膳食质量)。
    结果:参与者年龄较大(平均值,SD)46.1±11.9年,平均BMI为25.6±4.88kg/m2,主要为女性(73%)。95%的参与者是零食(每天≥1次零食;n=813);平均每日零食摄入量为2.28次零食/天(占每日卡路里的24±16%;203±170千卡);44%的参与者对膳食和零食质量不一致。在零食中,总体零食摄入频率和零食能量的数量与心脏代谢风险标志物无关.然而,较低的零食质量(SDI范围1-11)与较高的血液标志物有关,包括空腹甘油三酯升高(TG(mmol/L)β;-0.02,P=0.02),餐后TG(6hiAUC(mmol/L。s);β;-400,P=0.01),空腹胰岛素(mIU/L)(β;-0.15,P=0.04),胰岛素抵抗(HOMA-IR;β;-0.04,P=0.04)和饥饿(量表0-100)(β;-0.52,P=0.02)(多次测试调整后P值无统计学意义)。傍晚吃零食(≥晚上9点;31%)与较低的血液标志物相关(HbA1c;5.54±0.42%vs5.46±0.28%,葡萄糖2hiAUC;8212±5559vs7321±4928mmol/Ls,P=0.01和TG6hiAUC;11,638±8166vs9781±6997mmol/L。s,P=0.01)与所有其他零食时间相比(多次测试后HbA1c仍然显着)。
    结论:零食质量和食用时间是简单的饮食特征,可能有针对性地提高饮食质量,具有潜在的健康益处。
    背景:NCT03479866,https://clinicaltrials.gov/ct2/show/NCT03479866?term=NCT03479866&draw=2&rank=1。
    BACKGROUND: Snacking is a common diet behaviour which accounts for a large proportion of daily energy intake, making it a key determinant of diet quality. However, the relationship between snacking frequency, quality and timing with cardiometabolic health remains unclear.
    METHODS: Demography, diet, health (fasting and postprandial cardiometabolic blood and anthropometrics markers) and stool metagenomics data were assessed in the UK PREDICT 1 cohort (N = 1002) (NCT03479866). Snacks (foods or drinks consumed between main meals) were self-reported (weighed records) across 2-4 days. Average snacking frequency and quality [snack diet index (SDI)] were determined (N = 854 after exclusions). Associations between snacking frequency, quality and timing with cardiometabolic blood and anthropometric markers were assessed using regression models (adjusted for age, sex, BMI, education, physical activity level and main meal quality).
    RESULTS: Participants were aged (mean, SD) 46.1 ± 11.9 years, had a mean BMI of 25.6 ± 4.88 kg/m2 and were predominantly female (73%). 95% of participants were snackers (≥ 1 snack/day; n = 813); mean daily snack intake was 2.28 snacks/day (24 ± 16% of daily calories; 203 ± 170 kcal); and 44% of participants were discordant for meal and snack quality. In snackers, overall snacking frequency and quantity of snack energy were not associated with cardiometabolic risk markers. However, lower snack quality (SDI range 1-11) was associated with higher blood markers, including elevated fasting triglycerides (TG (mmol/L) β; - 0.02, P = 0.02), postprandial TGs (6hiAUC (mmol/L.s); β; - 400, P = 0.01), fasting insulin (mIU/L) (β; - 0.15, P = 0.04), insulin resistance (HOMA-IR; β; - 0.04, P = 0.04) and hunger (scale 0-100) (β; - 0.52, P = 0.02) (P values non-significant after multiple testing adjustments). Late-evening snacking (≥ 9 pm; 31%) was associated with lower blood markers (HbA1c; 5.54 ± 0.42% vs 5.46 ± 0.28%, glucose 2hiAUC; 8212 ± 5559 vs 7321 ± 4928 mmol/L.s, P = 0.01 and TG 6hiAUC; 11,638 ± 8166 vs 9781 ± 6997 mmol/L.s, P = 0.01) compared to all other snacking times (HbA1c remained significant after multiple testing).
    CONCLUSIONS: Snack quality and timing of consumption are simple diet features which may be targeted to improve diet quality, with potential health benefits.
    BACKGROUND: NCT03479866, https://clinicaltrials.gov/ct2/show/NCT03479866?term=NCT03479866&draw=2&rank=1.

    有限的研究调查了普通消费者中各种形式的烟熏/vaped大麻的数量变化,包括加拿大的新兴成年人(EA;18至29)。这些信息在当前与政治修正案(大麻合法化)有关的EA中新兴大麻行为的背景下尤其相关,与蒸发相关的肺部疾病(EVALI),和前所未有的大流行(COVID-19)。这项研究调查了加拿大娱乐性大麻使用合法化的影响,EVALI流行病,以及COVID-19大流行与吸食/吸食形式的大麻数量与性别差异的关系。EA回顾性地自我报告了草药的数量,哈希,浓缩物,接头尺寸,以及与三个连续发展相关的接头和电子烟墨盒的数量:合法化前,合法化后;评估前,评估后,COVID-19之前和COVID-19期间。大量使用者的草药使用量显着增加,轻型用户的电子烟数量显着增加。总的来说,随着时间的推移,大麻形式的平均使用量呈上升趋势。男性消耗的所有大麻形式的数量高于女性。报告使用浓缩物的男性多于女性(p<0.05)。这些发现揭示了与性别相关的各种大麻形式的吸食量的独特方面,并提供了与不断变化的社会和文化背景相关的大麻消费行为的初步证据。
    Limited research examines changes in quantities of various forms of smoked/vaped cannabis among regular consumers, including emerging adults (EAs; 18 to 29) in Canada. This information is particularly relevant in the current context of emerging cannabis behaviors among EAs related to political amendments (legalization of cannabis), vaping-related lung illnesses (EVALI), and unprecedented pandemics (COVID-19). This study investigated the impact of legalizing recreational cannabis use in Canada, the EVALI epidemic, and the COVID-19 pandemic on the quantity of smoked/vaped forms of cannabis in relation to gender differences. EAs retrospectively self-reported the quantity of herb, hash, concentrates, joint size, and the number of joints and vaping cartridges in relation to three consecutive developments: pre-legalization, post-legalization; pre-EVALI, post-EVALI, pre-COVID-19, and during COVID-19. The quantity of herb use significantly increased among heavy users, and vaping quantity significantly increased among light users. Overall, an increasing incremental trend was observed in the average quantity of cannabis forms used over time. Males consumed higher quantities of all cannabis forms than females. More males than females reported using concentrates (p < 0.05). These findings reveal unique aspects of the amount of various cannabis forms smoked/vaped in relation to gender and provides preliminary evidence of cannabis consumption behaviors in relation to changing social and cultural contexts.
