Inadequate Sunlight Exposure as A Risk Factor for Nutritional Rickets: A Systematic Review

Abstract

Insufficient sunlight exposure significantly contributes to the development of nutritional rickets, highlighting the critical importance of sunlight in maintaining optimal bone health and preventing this debilitating condition. Nutritional rickets, a preventable skeletal disorder, has significant implications for child health and development, particularly where there is limited sunlight exposure. Adequate sunlight exposure, especially in the form of ultraviolet B (UVB) radiation, is essential for synthesizing and maintaining optimal vitamin D levels, which are key in preventing nutritional rickets.  This systematic review aims to comprehensively analyze the relationship between inadequate sunlight exposure and the development of nutritional rickets among children. The review could inform effective preventive strategies by identifying the precise levels of sunlight exposure needed for healthy development and the factors contributing to inadequate exposure. Literature was searched through Google scholar, PubMed (Medline), Cochrane, and Elsevier using the following key terms; Nutritional rickets, Sunlight exposure, and vitamin D deficiency. Only peer-reviewed articles and research theses were included. Additionally, only literature reporting on nutritional rickets as a result of inadequate sunlight exposure practices were included. A total of 9 papers were included in the review. Findings such as Limited Sunlight Exposure with factors such as closed housing environments, urbanization, and cultural practices contributing to this phenomenon, Misconceptions and Fear regarding potential harms associated with sunlight exposure, such as skin cancer, sterility, and blindness, Disparities in Knowledge and Practices about sunlight exposure, Environmental Influences such as housing conditions and access to outdoor spaces significantly influence sunlight exposure opportunities for children. Interventions aimed at enhancing sunlight accessibility and creating sun-safe environments are crucial for optimizing exposure and preventing rickets. Comprehensive strategies are necessary to address sunlight exposure practices' complexities, including education, cultural sensitivity, policy reforms, and environmental modifications. Integrating these interventions is essential for promoting optimal sunlight exposure and improving child health outcomes.
