Attitudes and Knowledge of the Harmful Effects of Waterpipe Tobacco Smoking among university students: A study from Jordan.

Waterpipe tobacco smoking (WTS) is an emerging behavior worldwide, especially among the youth. It continues to spike in the Middle-Eastern region. WTS is associated with many harmful health-related outcomes.Objective: Herein, the attitude, knowledge, and factors affecting the knowledge of university students toward the detrimental effects of WTS were examined. This was a cross-sectional study where university students filled an online questionnaire that was available between October 2019 and May 2020. A total of 966 questionnaires were filled. About 40% of participants were current waterpipe smokers. Around 30% of participants stated that WTS is not addictive, and about third of them indicated that smoking waterpipe is an essential part of social gathering and is socially accepted behavior. Half of participants (55.8%) were knowledgeable about the major harmful consequences of WTS. Older students were more knowledgeable as compared to younger ones. In contrast, students from non-medical colleges and waterpipe smokers were less knowledgeable in comparison to those in medical colleges and non-smokers, respectively. More targeted health campaigns to control the use of WTS among university students should be implemented.

Waterpipe Tobacco Smoke Exposure during Lactation-Susceptibility of Reproductive Hormones and Oxidative Stress Parameters in Male Progeny Rats.

There is a growing evidence for the public health hazards associated with waterpipe tobacco smoking (WTS). While the adverse effects of WTS exposure during pregnancy on the offspring are widely reported, its impact during breastfeeding remains less understood. The effects of WTS exposure during lactation on the reproductive hormones and oxidative stress biomarkers of adult male progeny were examined. Lactating rats received either fresh air (controls) or mainstream WTS for 1 h twice/day from day 4 to day 21 of lactation. The offspring was then followed up until week 20. The data indicated that WTS exposure in the lactating animals reduced the levels of follicle-stimulating hormone (FSH), prolactin (P < 0.05), luteinizing hormone (LH) (P = 0.1146), and estradiol (P = 0.0773) in the blood in male progeny. While the activities of testicular superoxide dismutase (SOD), glutathione peroxidase (GPx) and the levels of thiobarbituric acid reactive substances (TBARS) and blood levels of testosterone (P >0.05) remained unaltered, the activity of catalase increased significantly indicating an increased oxidant load in the WTS exposed rats compared to the controls. WTS exposure during lactation impairs male reproductive hormonal profile, augments oxidative damage, and potentially affects male fertility in male offspring rats.
