There is a common belief among the laity and even physicians that sun exposure is a useful source of vitamin D. However, despite the fact that sun exposure occurs almost throughout the year in India, vitamin D deficiency is widely prevalent. Although several authors have reported on the duration of sun exposure required to synthesize adequate amounts of vitamin D in the human body, they have not followed a standard and uniform protocol for measurement of sun exposure and vitamin D synthesis. For these and many other reasons, the results are difficult to interpret. The American Academy of Pediatrics (AAP) has clearly stated that infants should be protected from the sun as much as possible and vitamin D requirements should be met through diet and fortified foods rather than deliberate sun exposure. However, this recommendation is frequently ignored in clinical practice. This review aims to summarize the available literature on benefits and harm of unprotected sun exposure in infants and children with a focus on skin phototype IV to VI. Dermatologists and pediatricians in India should counsel parents about the need for sun protection, especially in fair-skinned infants and children.
外行甚至医生中普遍存在一种观点,即阳光照射是维生素D的有益来源。然而,尽管在印度几乎全年都有阳光照射,但维生素D缺乏症却广泛流行。尽管有几位作者报告了人体合成足够量维生素D所需的阳光照射时长,但他们在测量阳光照射和维生素D合成时并未遵循标准且统一的方案。由于这些以及许多其他原因,结果难以解释。美国儿科学会(AAP)明确表示,应尽可能保护婴儿免受阳光照射,维生素D需求应通过饮食和强化食品来满足,而不是刻意进行阳光照射。然而,这一建议在临床实践中经常被忽视。本综述旨在总结关于婴儿和儿童无保护阳光照射的益处和危害的现有文献,重点关注皮肤光型IV至VI。印度的皮肤科医生和儿科医生应向家长提供有关防晒必要性的咨询,尤其是对皮肤白皙的婴儿和儿童。
