Introduction Tobacco use has been associated with many health risks that can lead to premature death. This study aims to assess the national prevalence of tobacco consumption and the associated determinants in Saudi Arabia.  Methods The study involved a cross-sectional national survey of 5175 individuals conducted across the 13 official regions of Saudi Arabia. The sample included individuals aged 18 years and above from both genders recruited using a quota sampling technique. Data collection was carried out between September 2018 and May 2019 through Web-based computer-assisted telephone interviews (CATIs). Participants were asked to report their current consumption of tobacco products including cigarettes, shisha (waterpipe), smokeless tobacco, cigars, pipes, and electronic cigarettes/vaping. Knowledge of specific health risks associated with smoking and public perceptions of the smoking phenomenon were also assessed among never smokers, smokers, and former smokers. Results The national prevalence of tobacco consumption was 24.02% (1120/5175). Cigarettes were the most prevalent tobacco product consumed (16.18%; 95% CI: 14.5881–17.7663), and daily cigarette smoking prevalence was the highest (14.12%; 95% CI: 12.6433–15.5924). Shisha smoking prevalence was 8.12% (95% CI: 6.8054–9.4352). E-cigarette use prevalence was 2.22% (95% CI: 1.5770–2.8711). The most common tobacco product used among males was cigarettes (15.13%; 95% CI: 13.58–16.67), while shisha was commonly used among females (1.57%; 95% CI: 1.11–2.04). Cigarette smoking prevalence was the highest in the Aljawf region (21.12%; 95% CI: 17.07–25.18), shisha smoking prevalence was the highest in the Makkah region (12.41%; 95% CI: 8.64–16.17), whereas smokeless tobacco use was prevalent in the Najran region (4.75%; 95% CI: 2.81–6.70). Males (AOR: 8.17; 95% CI: 5.98–11.71; P < 0.0001), young adults below 45 years of age (AOR: 2.12; 95% CI: 1.50–2.98; P < 0.0001), and those with below a bachelor’s degree (AOR: 1.34; 95% CI: 1.01–1.77; P = 0.0396) were more likely to consume tobacco compared with others. The population mean knowledge scores of health risks associated with smoking among smokers was 1.91 ± 1.72 (Range: 0–10), with the highest knowledge scores (2.16 ± 1.68) among former smokers. Only 46.53% (95% CI: 44.30–48.75) of the population are bothered “to very large extent” by smoking health consequences. Conclusions Tobacco consumption is prevalent in Saudi Arabia. Different forms of tobacco use were reported, and the most common was cigarettes, followed by shisha and then electronic cigarettes. Tobacco use remains one of the major threats to the health of the population in Saudi Arabia.

Although the micronutrient status of a population is of high national priority, as it critically impacts public health, limited data is available for quantifying the micronutrient status in Saudi Arabia. We aimed to provide comprehensive, epidemiological, descriptive data regarding micronutrient levels in Saudi adults. This cross-sectional study included 3432 adults aged ≥ 18 years (mean age, 37.7 ± 11.7 years; women, 51.2%) across all 13 Saudi administrative regions (March 2019–November 2021). Laboratory data for 14 micronutrients (8 vitamins, 4 minerals, and 2 nonessential heavy metals) were characterized using descriptive analysis. Vitamin D deficiency (64.3%) was the most prevalent, followed by vitamin B2 (44.9%) and A (9.6%) deficiencies. Among minerals, iron deficiency was the most prevalent (23.2%), followed by zinc (15.3%) and copper (8.7%) deficiencies. Most Saudi adults exhibited normal arsenic (99.7%) and mercury (99.9%) levels. Men exhibited significantly higher vitamin B2, B9, and D deficiencies than women, while women exhibited higher vitamin A, B12, iron, and zinc deficiencies than men. Younger adults demonstrated a significantly higher prevalence of vitamin D and iron deficiencies, whereas older adults exhibited a higher prevalence of vitamin B1 and magnesium deficiencies. As micronutrient deficiencies are a public health concern, health policies and programs need to be developed and implemented to address them.

Background: Use of nutrition facts labels can be associated with healthier eating behaviors; however, consumers currently face difficulty understanding these labels or do not use them often. Thus, improving healthy grocery shopping behaviors among consumers might increase the overall health of the community. Aim: The study aims to explore consumers’ behavior during grocery shopping and measure their basic knowledge regarding food product labels. Method: A national observational study (cross-sectional) was carried out on a convenience sample of Saudi Arabian residents aged 18 years and above. The data were obtained from all 13 administrative regions in Saudi Arabia at three different major supermarkets in each region. The data were analyzed using descriptive analysis, and binary logistic regression was used to investigate behavior variables. Results: A total of 12,675 participants were observed; of those, 52.2% did not interact with the product before putting it in their shopping cart. The study found that the production date (66.6%) and expiry date (51%) were the most frequently checked aspects of food labels; they were checked more frequently than nutrition facts (29%). Furthermore, there was a low level of dietary knowledge among consumers and a moderate level of believing food packages and media claims. Conclusions: Our results suggest that the Saudi community's understanding of food product information is limited and greater awareness and community education campaigns are required to improve the use of nutritional labels and increase nutritional knowledge.
