Introduction Waterpipe smoking (WPS), which is otherwise called shisha, narghile, and Gozaor hookah, has been one of the most common strategies for tobacco use in developing nations for approximately 400 years [1-4]. Its device consists of a head, body, water bowl, and hose [5]. WPS contains tobacco-specific nitrosamines and glycerol nicotine, which are derived from raw materials, and it produces chemical substances (such as carbon monoxide (CO)), which are synthesised during smoking, and produces 34 polyaromatic hydrocarbons, which are synthesised and transmitted when smoking [6]. WPS has been used for around 400 years [1]; the Arabian Peninsula, Turkey, India and Pakistan are among the countries where WPS has become increasingly popular [7]. WPS has considerable effects, both short and long term, on human health. Its short-term health effects include headache, nausea, lethargy, and fainting. Waterpipe smoking also impairs baroreflex control, which helps control blood pressure. Various long-term health effects may be caused including pulmonary diseases (e.g. chronic obstructive pulmonary disease) and coronary heart disease. WPS appears to increase the risk of several cancers such as lung, oral, oesophageal, and gastric cancer [3, 8, 9]. WPS also leads to numerous communicable diseases and respiratory diseases such as influenza, hepatitis and TB [10, 11]. Mahfouz et al. studied the prevalence of tobacco use and its associated factors in 4100 students, both male and female, at Jazan University, and states that (according to the World Health Organization) around four million people die annually due to tobacco use worldwide [12]. The percentage of males who used WPS was 12.1% (95% Confidence Interval [CI]: 10.6-13.8), whereas that of females was 2.5% (95% CI: 1.8-3.4). Hassan et al. conducted a study in Riyadh, Saudi Arabia in 2014, with 156 students from Al-Ghad International College, to assess the prevalence of tobacco smoking [13]. The study showed of those surveyed: 42.3% were current smokers, 17.9% were past smokers, 34.8% were cigarette smokers and 21.2% were WPS users. In 2010, Taha et al. conducted a cross-sectional study at Lord Faisal College in Dammam City, Saudi Arabia, to investigate the prevalence of WPS among male understudies from three medical colleges [14]. The general prevalence of WPS was found to be 12.6% (n = 47). The worldwide prevalence of WPS has also been studied. In Aleppo, Syria (2014), WPS prevalence was 25.5% and 4.9% among male and female university students,

Background Diabetic foot is one of the significant complications of diabetes mellitus, associated with a high risk of morbidity and mortality. Patients' knowledge of, and willingness to practice, good footcare are essential and may decrease these risks. This study was conducted to assess adult diabetic patients' knowledge of footcare and willingness to put their knowledge into practice. Method A cross‐sectional observational study was conducted on adult diabetic patients in the central area of the Jazan Region using patients' responses to a questionnaire. Descriptive statistics were calculated for study variables, and the Pearson chi‐squared test was used to compare categorical data. Results A total of 410 diabetic patients were included in this study. The mean age of the participants was 56.7 years. The mean duration of their diabetes mellitus (DM) to date was 9.2 years, and 63% had complications of diabetes. For the questionnaire, 56% of the patients gave incorrect responses to the knowledge of the footcare section and 81% to the willingness to practice footcare section. Highly educated patients have better knowledge and practice of diabetic footcare than those who are less educated (77% vs. 23%, p < 0.05), (37% vs. 20%, p < 0.05), respectively. A statistically significant difference exists between patients with good and poor knowledge scores. Conclusion This study demonstrates that the knowledge and practice of footcare among DM patients are poor. Therefore, appropriate patient information programs are needed to increase patients' understanding of their illness and how to manage it.
