The use of traditional medicinal plants in Saudi Arabia stems mainly from consumers’ belief in prophetic medicine. This study was conducted to explore changes in patients’ use of dietary or herbal supplements among individuals infected with COVID-19 before and during infection and the association between herbal or dietary supplements and hospitalization. A cross-sectional, questionnaire-based study was conducted enrolling symptomatic patients who had recently recovered from COVID-19. Data were collected through phone interviews, and McNemar’s test was used to investigate changes to consumption of dietary or herbal supplements before and during infection. Multivariable logistic regression was used to investigate the association between supplements use during patients’ infection and hospitalization. A total of 738 patients were included in this study, of whom 32.1% required hospitalization. About 57% of participants were male with a mean age of 36.5 (±11.9) years. The use of lemon/orange, honey, ginger, vitamin C, and black seed among participants significantly increased during their infection. In contrast, patients using anise, peppermint, and coffee peel before their infection were more likely to stop using them during their infection. In addition, using lemon/orange (p < 0.0001), honey (p = 0.0002), ginger (p = 0.0053), vitamin C (p = 0.0006), black seed (p < 0.0001), peppermint (p = 0.0027), costus (p = 0.0095), and turmeric (p = 0.0012) was significantly higher among nonhospitalized patients than hospitalized ones. However, in the multivariable logistic regression, only use of vitamin C (OR = 0.51; 95% CI 0.33–0.79), peppermint (OR = 0.53; 95% CI 0.31–0.90), and lemon/orange (OR = 0.54; 95% CI 0.33–0.88) was associated with significantly lower odds of hospitalization. The study reveals that patients’ consumption of dietary or herbal supplements changed in response to their COVID-19 infection, with hospitalized patients having a lower likelihood of using these supplements. Because some supplements were associated with lower odds of hospitalization, these supplements or their bioactive components should be further investigated as feasible options for COVID-19 treatment.

The impact of different sociodemographic and clinical characteristics on the COVID-19-related morbidity and mortality rates have been studied extensively around the world; however, there is a dearth of data on the impact of different clinical and sociodemographic variables on the COVID-19-related outcomes in Saudi Arabia. This study aimed to identify those at high risk of worse clinical outcomes, such as hospitalization and longer length of stay (LOS) among young and middle-aged adults (18 to 55 years). In this questionnaire-based cross-sectional study, 706 patients with real-time polymerase chain reaction (RT-PCR) confirmed COVID-19 infection were interviewed. Patients’ demographic characteristics, dietary habits, medical history, and lifestyle choices were collected through phone interviews. Patients with chronic health conditions, such as diabetes and hypertension, reported a higher rate of hospitalization, ICU admission, oxygen-support needs, and a longer period of recovery and LOS. Multiple logistic regression showed that diabetes, hypertension, and pulmonary disease (e.g., asthma and chronic obstructive pulmonary disease (COPD)) were associated with a higher risk of hospitalization and longer LOS. Multiple logistic regression showed that symptoms of breathlessness, loss of smell and/or taste, diarrhea, and cough were associated with a longer recovery period. Similarly, breathlessness, vomiting, and diarrhea were associated with higher rates of hospitalization. The findings of this study confirm the similarity of the factors associated with worse clinical outcomes across the world. Future studies should use more robust designs to investigate the impact of different therapies on the COVID-19-related morbidity and mortality in Saudi Arabia.

The world is still in need of an effective therapy to treat coronavirus disease-19 (COVID-19). This cross-sectional study was conducted on COVID-19 survivors in Saudi Arabia to investigate the influence of a healthy diet on the recovery time from COVID-19. A questionnaire was developed to assess participants’ dietary habits, based on the 2015 Dutch food-based dietary guidelines. A total of 738 COVID-19 survivors participated in the study, of whom 237 (32.1%) were hospitalized for COVID-19 treatment while 501 (76.9%) were not hospitalized, and 320 (43.4%) were females and 418 (56.6%) were males. Overall, no significant difference was noted in healthy diet score between males and females; however, this score was significantly lower for Saudis compared to non-Saudis. Among the non-hospitalized patients, eating a more healthy diet was associated with a shorter duration of recovery (p < 0.05) and was significantly affected by gender (15.8 ± 9.3 male vs. 12.1 ± 8.9 female; p < 0.001) and marital status (12.1 ± 8.4 singles vs. 13.7 ± 9.3 married vs. 16.1 ± 11.8 divorced; p < 0.05). In contrast, no significant correlation was found with age or BMI. In this study, a more healthy diet was associated with a shorter duration of recovery from COVID-19. However, further studies are needed to thoroughly investigate the relationship between diet and recovery time from COVID-19.
