Assessment of Vitamin D Levels Among a Sample of Medical Laboratory Visitors in Misurata City and their Association with Seasonal Variations

Abstract

Vitamin D deficiency is one of the most prevalent health issues in contemporary societies, affecting individuals of both sexes across various age groups. This study aimed to assess the concentration levels of vitamin D among visitors to medical laboratories in Misurata City from September 2019 to August 2023. Data collection involved two approaches: blood samples were obtained from visitors between January and August 2023, while vitamin D level records from September 2019 to December 2022 were retrieved from laboratory archives.

The study’s findings revealed a widespread deficiency in vitamin D levels among the participants throughout the study period. Notably, the deficiency was significantly higher in females (80.42%) than males (19.57%). In terms of age groups, individuals aged 35–45 years were identified as the most susceptible, with a deficiency rate of 34.10%, showing statistically significant differences.

Regarding the relationship between vitamin D levels and seasonal variations, the study found that winter and spring had the highest prevalence of vitamin D deficiency, with statistically significant differences compared to other seasons. Conversely, vitamin D levels were observed to increase during autumn and summer.

The findings further demonstrated that vitamin D levels among medical laboratory visitors were influenced by factors such as gender, age group, and seasonal variation. These results underscore the importance of monitoring vitamin D concentrations to mitigate the risk of developing conditions associated with its deficiency, such as hair loss and chronic diseases like kidney failure.
