Overview

Important risk factors for vitamin D deficiency that can not be changed are non-western ethnicity, older age and colder seasons. [1] Sedentary life style and less sun exposure play a significant role in increasing vitamin D deficiency. [2]

Risk Factors

The risk factors of vitamin D deficiency can be categorized into three main groups; non-modifiable risk factors, modifiable risk factors, and also factors that are related to mothers' conditions.

Non-modifiable risk factors

  • Age
  • Ethnicity: non-western ethnicity like African, Asian, Turkish, and Moroccan children are at greater risks than children of western ethnic background.[3]
  • Dark skin color [4]
  • Season: late fall, winter, and spring
  • Geography: higher latitude, lower altitude, cloudy weather [5]

Modifiable risk factors

  • Life style including sedentary behavior, high child television watching, and less outdoor activities[1]
  • Less sun exposure including use of sunscreen or clothing [2]
  • Obesity [6][7]
  • Being underweight [3]
  • Less milk drinking
  • Not taking vitamin D supplements
  • Exclusive breastfeeding

Maternal risk factors

  • Lower maternal age
  • Lower household income
  • Multiparity
  • Higher maternal BMI
