The Unseen Consequence of Lockdowns: Vitamin D Deficiency in Children
As the world grapples with the ongoing COVID-19 pandemic, another health crisis is silently unfolding among our youngest population: vitamin D deficiency. A recent study published in Italian Journal of Pediatrics sheds light on this overlooked issue.

The Source Article's Abstract
SARS-Cov2 infection began to spread worldwide since December 2019; on March 2020, the World Health Organization characterized its related disease, named COVID-19, as a pandemic. In Italy, to contain the spread of infection a severe lockdown in the spring 2020 was instituted. Other less severe restrictions were imposed in the winter 2020-2021 and in the spring 2021. The containment measures caused a series of consequences for the population and, in particular, for children and adolescents that presented psychophysical problems. The aim of this manuscript is to investigate the serum levels of vitamin D in children and adolescents before, during and after the lockdown consequent to COVID-19 pandemic.
This is a retrospective cross-sectional study, including all children and adolescents between 1 to 18 years referring to the Pediatric Endocrinology Service of the University Hospital of Verona, Italy, between January 2019 and December 2021. All patients affected by clinical conditions that involve vitamin D metabolism or assuming vitamin D supplementation were excluded.
In total, 491 children (36.7% males and 63.3% females) were enrolled in this study. The vitamin D levels decreased over time: 28.3 Â± 10.2 ng/mL in 2019; 28.2 Â± 11.4 ng/mL in 2020 and 24.9 Â± 10.1 ng/mL in 2021 (p < 0.05). The vitamin D levels are significant higher in summer and in autumn in comparison with the levels of winter and spring, regardless of the examined years.
The measures adopted to contain the COVID-19 pandemic led to a reduction of serum levels of vitamin D in pediatric population, probably due to the reduced solar exposure. This may have severe consequences on the bone metabolism of those children who did not present optimal vitamin D levels even before the lockdown. Therefore, an adequate supplementation of vitamin D is necessary from the end of fall to the beginning of spring (November-April) in all children and adolescents living in Northern Italy.

Why Vitamin D Matters
Vitamin D is not just another nutrient; it’s crucial for bone health, immune function, and overall well-being. This ‘sunshine vitamin’ deficiency is particularly concerning in growing children.
According to the study, the lockdown measures have led to a significant reduction in vitamin D levels in children, irrespective of gender, age, weight, and season.
Lockdowns and Sun Exposure
The study highlights that the restriction measures and the prolonged home confinement have reduced sun exposure, affecting vitamin D synthesis. This is alarming because children can only maintain an adequate vitamin D status from endogenous stores or exogenous supplementation during late fall, winter, and early spring.
Moreover, the study found that vitamin D levels were lower in 2021 compared to 2020, suggesting that the impact of restrictions is cumulative.
Implications for Pediatric Health
- Increased Risk of Bone Disorders: Vitamin D is essential for calcium absorption, which is crucial for bone health.
- Immune System Compromise: Lower vitamin D levels can make children more susceptible to infections.
- Long-term Health Consequences: The deficiency could have long-term implications that we may only understand in the future.
What Should Pediatricians Do?
The study suggests vitamin D supplementation in all children and adolescents from the end of fall to the beginning of spring. Pediatricians should pay particular attention to these categories of patients and advise them to supplement vitamin D.
Given the study’s findings, it’s clear that more proactive measures are needed to combat this silent epidemic.
