- Topic and question
- Prevalence of vitamin D deficiency among female university students in Riyadh, and its association with sun exposure, diet and supplements. Deficiency is common in Saudi Arabia despite abundant sunshine; few data on female university students
- Method
- Cross-sectional study, 2025; 312 female students at one university; serum 25-hydroxyvitamin D; structured questionnaire on daily sun exposure, clothing, diet and supplements; deficiency below 20 ng/mL; logistic regression
- Findings
- 68% deficient; median 16.2 ng/mL; under 15 minutes of sun a day: adjusted OR 2.4 (95% CI 1.4–4.1); regular supplement use: OR 0.38 (95% CI 0.21–0.69); dairy intake not significantly associated

Vitamin D deficiency among female university students in Riyadh: a cross-sectional study
Title
Vitamin D deficiency is common in Saudi Arabia despite abundant sunshine, but data on young women at university are limited1. This study estimated the prevalence2 of vitamin D deficiency among female university students in Riyadh and examined its association with sun exposure, diet and supplement use. In a cross-sectional study conducted in 2025, we measured serum 25-hydroxyvitamin D in 312 female students at one university and collected data on daily sun exposure, clothing, diet and supplements with a structured questionnaire. Deficiency was defined as a level below 20 ng/mL3, and associations were examined with logistic regression. Overall, 68% of participants were deficient (median 16.2 ng/mL). Students who spent less than 15 minutes a day in the sun were more likely to be deficient (adjusted odds ratio 2.4, 95% CI 1.4–4.1)4, while regular supplement use was associated with lower odds (0.38, 95% CI 0.21–0.69). Dairy intake was not significantly associated5 with vitamin D status. These findings suggest that deficiency is widespread in this group and that supplementation may be a more practical strategy6 than increased sun exposure.
The abstract
Note 1: The gap in half a sentence, right after the background. It justifies the whole study.
Note 2: The aim uses the same words as the title, so the reader knows exactly what was measured.
Note 3: Defining the outcome makes the 68% meaningful and comparable with other studies.
Note 4: Results with effect sizes and confidence intervals, not just “significant”.
Note 5: A null result is reported too. Leaving it out would make the abstract less honest.
Note 6: One cautious sentence on what the findings mean. “May” matches what a cross-sectional study can show.

Vitamin D is very important for the health of the human body.
Vitamin D deficiency is common in Saudi Arabia despite abundant sunshine, but data on young women at university are limited.
The results showed that there is a significant relation between sun and vitamin D.
Students who spent less than 15 minutes a day in the sun were more likely to be deficient (adjusted odds ratio 2.4, 95% CI 1.4–4.1).
In this study we will measure vitamin D in 312 students.
In a cross-sectional study conducted in 2025, we measured serum 25-hydroxyvitamin D in 312 female students.
Questions people ask
What is the difference between a structured and an unstructured abstract?
A structured abstract has headings (Background, Methods, Results, Conclusions); an unstructured one, like this, is a single paragraph that follows the same order. Use whichever the journal or university asks for.
Which tense should an abstract use?
Past tense for what you did and found (“we measured”, “68% were deficient”), present tense for general facts and for what the findings suggest.
How long should an academic abstract be?
Usually 150 to 300 words; follow the journal’s limit. This one has about 175 words, not counting the title.
Every writer in this library is fictional, and so is every detail about them. Universities and companies appear only as places someone applies to; the professors, papers and facts mentioned around them are invented for teaching. Use the examples to learn the moves, never as text to copy: committees notice, and your own facts are stronger.
