A study on the general public's awareness of vitamin D deficiency was carried out in Taif, Saudi Arabia in 2023. The investigation has revealed that 23.9% of people were very aware of vitamin D deficiency. It is less than one-third of the total population. However, roughly 40.6% of people were not well aware of this. A report to on the findings, almost all of the participants (91.6%) comprehended that exposure to the sun produces vitamin D in the skin. However, respondents also thought that living in cloudy areas increased the likelihood of vitamin D deficiency (60.1%) and that frequent sun exposure could result in vitamin D poisoning (66.3%).[1]
In we found that 15 minutes of sun exposure on the arms, torso, and legs on both the front and backsides of the body resulted in significantly elevated blood vitamin D3 by an average of 9.8 mol/L. This is because human D3 production decreases with age (by about 13% every decade), though it can still happen up to the age of 120. [2]
This study's goals were to determine the major risk factors that may be connected to vitamin D deficiency by evaluating a number of variables related to sociodemographic, lifestyle, and health status characteristics, as well as dietary supplement intake, and to assess vitamin D deficiency in a sample of women living in Riyadh, Saudi Arabia. In total, 166 Saudi Arabian women who reside in Riyadh participated in this study. The study subjects' sociodemographic and lifestyle details are shown; 85.5% of them are Saudi citizens. Younger women, aged 30-49, made up 57.2% of the participants. The majority of participants, or 77.7%, reside in homes with easy access to sunlight. In actuality, 40.9% of the women who took part had little to no exposure to sunlight. Merely 15.1% of them possessed regular sun exposure.

we found that among otherwise healthy children the study aim to study sought to ascertain whether vitamin D level among healthy Saudi youngsters was impacted by physical activity and sun exposure , vitamin D insufficiency was highly prevalent. Vitamin D level was impacted by less than three times a week of outdoor physical activity and little sun exposure.

Of the total respondents, 161 (10%) had normal vitamin D levels, 749 (46.5%) had vitamin D deficiency, and 649 (40.3%) had not had a vitamin D test. Only 31 (4.13%) had vitamin D levels above 60 pg/ml. The levels of vitamin D were 5–15 pg/ml in 431 (57.54%), 16–25 pg/ml in 247 (32.9%), and 26–35 pg/ml in 89 (11.88%). According to data analysis, respondents had a high prevalence of vitamin D deficiency. Among the population under study, there was a positive correlation between anxiety and vitamin D deficiency, Sanaa Moharram Kamal et al, 2019.[5]
A‏ study about Vitamin D deficiency and associated factors out in United Arab Emirates in 2020 multivariate model found an inverse relationship between daily clothing and sun exposure and serum 25(OH)D concentrations, The purpose of this investigation was to find the prevalence of vitamin D insufficiency and investigate its correlations which are favorably linked with previous vitamin D ingestion. BMI and vitamin D levels did not significantly correlate [6]
