Quick Answer
Vitamin A Skin Health Randomized Trial has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: It contributes to millions of deaths each year and is strongly associated with comorbidities such as hypertension, type 2 diabetes, and cardiovascular disease.In Brazil, the burden is similarly substantial, with 39.6% of the population classified as overweight and 23.8% as obese.The rising prevalence of obesity highlights the need to identify modifiable risk factors and develop effective interventions.
Key Takeaways
- 01It contributes to millions of deaths each year and is strongly associated with comorbidities such as hypertension, type 2 diabetes, and cardiovascular disease.In Brazil, the burden is similarly substantial, with 39.6% of the population classified as overweight and 23.8% as obese.The rising prevalence of obesity highlights the need to identify modifiable risk factors and develop effective interventions. [Menezes-Júnior Luiz (2026)]
- 028 9 Shift workers are particularly vulnerable because reduced sunlight exposure limits endogenous vitamin D synthesis. [Menezes-Júnior Luiz (2026)]
- 03Studies have shown that shift workers have an 80% higher risk of hypovitaminosis D than individuals in other occupational groups.In this population, Batista et al.reported a high prevalence of hypovitaminosis D (73%) and a significant association with increased visceral fat area (odds ratio [OR]: 2.4; 95% confidence interval [CI]: 1.1–5.2). [Menezes-Júnior Luiz (2026)]
- 041 2 Obesity is a chronic, multifactorial disease characterized by excessive adipose tissue accumulation and is among the most significant global public health challenges. [Menezes-Júnior Luiz (2026)]
The current Migaku evidence database contains 2 reusable source documents for Vitamin A Skin Health Randomized Trial. This answer focuses on benefits, uncertainty, and practical interpretation.

Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
