RESUMO

Objective: To explore the attitudes of medical students at King Saud University (KSU) toward online distance learning during the COVID-19 pandemic and to examine the effects of gender, academic year and level of computer skills on student attitudes toward distance learning. Methods: A previously validated questionnaire was distributed to participants via WhatsApp using a stratified random sampling method. Data were analyzed using SPSS version 26.0 statistical software. Means and standard deviations were used to examine quantitative variables, while frequencies and percentages were used to examine qualitative variables. Results: Our study included 533 students; 71.9% of participants were satisfied with online classes, while 59.6% struggled to receive explanations due to limitations to face-to-face interactions. Two-thirds of participants thought that online classes were more convenient because of their flexibility with respect to location. A similar proportion (65.3%) believed that in situations of distance learning, it was difficult to meet and work with friends. The majority (88.7%) of participants agreed that distance learning saved time and effort spent traveling to campus. Finally, most participants 355 (66.6%), favored blended learning, while only 111 (20.8%) of participants preferred in-class learning. Students in preclinical years had more negative attitudes regarding face-to-face interactions (66.5% vs 54.9%, P=0.027) and meeting with friends (69.3% vs 58.7%, P=0.026) than did students in clinical years. Gender and level of computer skills did not affect students' attitudes toward distance learning (P > 0.05). Conclusion: The majority of student participants felt that online distance learning was an effective option during the pandemic, but they preferred to preserve face-to-face teaching as a concurrent option. Attitudes toward certain aspects of distance learning were more negative among students in preclinical years than among students in clinical years. We did not find any effects of gender or level of computer skills on student attitudes toward distance learning.

RESUMO

Saudi Arabia has witnessed recent reforms and positive socio-political changes that have led to increased opportunities for women to participate in fitness centers. This study investigated protein supplement consumption among Saudi females compared with that among males and examined the knowledge and attitudes of the participants toward protein supplement use. A cross-sectional study was conducted in Riyadh using a previously validated, self-administered online survey. The questionnaire included items related to the prevalence, knowledge, attitudes, and practice of protein supplementation. The participants were 354 adults (58.2% were females). The results showed that over 47% of the participants attended fitness centers with more male (80.3%) than female (41%) attendees. Nearly 50% of the participants consumed protein supplements, with males (68.7%) using significantly (p < 0.001) more protein supplements than females (35.6%). The powdered form was most commonly consumed. The percentage of gym attendees (67.8%) who used protein supplements was higher than that among non-gym attendees (32.2%). Gaining muscles (56.1%) followed by compensating for protein deficiency (28.6%) were the reasons for taking protein supplements, with a significant gender difference (p < 0.001). Coaches provided the most information on protein supplements. The participants appeared to be knowledgeable about protein supplements. Although over 68% of protein supplement users suffered from various symptoms, only 20% of the participants thought that there was no risk in taking protein supplements, with significant gender differences. It was concluded that Saudi male participants are twice more likely to attend the gym and consume protein supplements compared with females. Of both genders, those attending the gym consumed more protein supplements than non-gym attendees.

RESUMO

Papain hydrolysis of camel whey protein (CWP) produced CWP hydrolysate (CWPH). Fractionation of CWPH by the size exclusion chromatography (SEC) generated fractions (i.e., SEC-F1 and SEC-F2). The angiotensin converting enzyme inhibitory activity (ACE-IA) and free radical scavenging actions were assessed for CWP, CWPH, SEC-F1, and SEC-F2. The SEC-F2 exerted the highest ACE-IA and scavenging activities, followed by CWPH. The protective effects of CWPH on thioacetamide (TAA)-induced toxicity were investigated in rats. The liver enzymes, protein profile, lipid profile, antioxidant enzyme activities, renal functions, and liver histopathological changes were assessed. Animals with TAA toxicity showed impaired hepatorenal functions, hyperlipidemia, and decreased antioxidant capacity. Treatment by CWPH counteracted the TAA-induced oxidative tissue damage as well as preserved the renal and liver functions, the antioxidative enzyme activities, and the lipid profile, compared to the untreated animals. The current findings demonstrate that the ACE-IA and antioxidative effects of CWPH and its SEC-F2 fraction are worth noting. In addition, the CWPH antioxidative properties counteracted the toxic hepatorenal dysfunctions. It is concluded that the hydrolysis of CWP generates a wide range of bioactive peptides with potent antihypertensive, antioxidant, and hepatorenal protective properties. This opens up new prospects for the therapeutic utilization of CWPH and its fractions in the treatment of oxidative stress-associated health problems, e.g., hypertension and hepatorenal failure.

RESUMO

BACKGROUND: Few studies have reported valid comprehensive data on lifestyle habits of Saudi college females. In addition, studies on sedentary behaviors (SBs) and the duration of sleep of Saudi college students are rare. Saudi females appear to be less physically active and therefore, at a higher risk of noncommunicable diseases (NCDs). Therefore, the purpose of this study was to investigate lifestyle patterns of Saudi college females, including physical activity (PA), SBs, duration of sleep, and dietary habits. MATERIALS AND METHODS: A cross-sectional study was conducted among females attending health science colleges of King Saud University, using multistage stratified cluster sample (n = 456). Weight, height, PA, SB, sleep, and dietary habits were all assessed using a previously validated questionnaire. RESULTS: Nearly half of the college females were physically inactive. Females exercised mostly at home or alone at no specific time of day. Their activity was for health reasons (43.4%) for weight loss (28.7%); lack of time (71.2%) was the primary reason for inactivity. The majority (>85%) of females spent more time in sedentary activity (>3 h/day) while 95% of females had insufficient sleep (<8 h/night). Over 40% of the participants consumed breakfast or vegetables 5 days or more per week, whereas the corresponding proportions for fruit and milk/dairy products intake were 19.4% and 58.4%, respectively. The proportions of college females who consumed less healthy foods for 3+ days/week were fairly variable, ranging from 21.1% for French fries to 60.4% for chocolates/candy. The predictors of total PA time were increased the duration of sleep and reduced intake of French fries/potato chips. CONCLUSIONS: Unhealthy lifestyle habit appears prevalent among Saudi college females. Efforts toward promoting PA, decreasing SB, and insufficient sleep and improving dietary habits in Saudi females are needed to reduce future risks of NCDs.

RESUMO

The study examined the associations between lifestyle habits and overweight/obesity among Saudi females attending health science colleges. A total of 454 female students were randomly recruited from five health science colleges at King Saud University, using a multistage stratified cluster sampling technique. Body weight and height were measured, and body mass index was calculated. All participants answered a validated questionnaire to assess physical activity (PA), sedentary behaviors (SB), sleep duration, and dietary habits. Results showed that the prevalence of overweight (21.4%) plus obesity (8.1%) among female participants was 29.5%. There was no significant difference between overweight/obese and nonoverweight/nonobese females in PA, screen time, sleep duration, or dietary habits. Overall, 50.4% of the participants were physically inactive (activity energy expenditure was <600 metabolic equivalent minutes per week). Active females showed significantly (p < 0.01) higher intakes of vegetables and fruits, lower chocolate/candy consumption (p = 0.05), and higher proportion of sufficient sleeping duration (>8 hours per night) (p < 0.001). It was concluded that half of the Saudi females in this study were physically inactive. Although PA positively impacted some of the lifestyle habits of college females, overweight/obesity was not associated with PA, SB, sleeping time, or dietary habits among the participants. Future research should attempt to elucidate the key factors involved in such relationship.
