Very low D if not Sept-Nov

Population-based data relating to vitamin D status of children in Northeast Asia are lacking. We conducted a cross-sectional study to determine the prevalence and determinants of vitamin D deficiency in 9595 schoolchildren aged 6–13 years in Ulaanbaatar (UB), the capital city of Mongolia. Risk factors for vitamin D deficiency were collected by questionnaire, and serum 25-hydroxyvitamin D (25[OH]D) concentrations were measured using an enzyme-linked fluorescent assay, standardized and categorized as deficient (25[OH]D <10 ng/mL) or not. Odds ratios for associations between independent variables and risk of vitamin D deficiency were calculated using multivariate analysis with adjustment for potential confounders. The prevalence of vitamins D deficiency was 40.6% (95% CI 39.7% to 41.6%). It was independently associated with female gender (adjusted odds ratio [aOR] for girls vs. boys 1.23, 95% CI 1.11–1.35), month of sampling (aORs for December–February vs. June–November 5.28 [4.53–6.15], March–May vs. June–November 14.85 [12.46–17.74]), lower levels of parental education (P for trend <0.001), lower frequency of egg consumption (P for trend <0.001), active tuberculosis (aOR 1.40 [1.03–1.94]), household smoking (aOR 1.13 [1.02 to1.25]), and shorter time outdoors (P for trend <0.001). We report a very high prevalence of vitamin D deficiency among Mongolian schoolchildren, which requires addressing as a public health priority.

VitaminDwiki: Overview of Rickets and vitamin D contains

Rate of rickets is usually < 0.1% of births, unless dark skin, breastfed, preemie, twin, Mongolian, or Russian
Rate of rickets has greatly increased with the drop in vitamin D levels during the past 40 years
400 IU can prevent/treat most rickets Turkey gave vitamin D to EVERY child and eliminated Rickets
Can have rickets without a low serum level of vitamin D (~20% of the time)
Giving enough Vitamin D to the mother (before and after birth) PREVENTS most forms of Rickets
Rate of rickets in some countries varies from 10% to 70% (typically poor health overall)
Rickets has been more than doubling in many countries
Rickets is strongly associated with severe breathing problems (weak ribs)
Bowed legs is not the primary indication of rickets    (3 other indications of rickets are seen more often)
Rickets is typically due to low cellular Vitamin D - April 2024
Some Rickets is due to poor genes - Vitamin D needed lifelong – June 2020
Vitamin D and Rickets consensus took 80 years

Rickets category has 127 items

• Rickets almost eradicated in counties giving free Vitamin D, perhaps the world can learn – Dec 2019
• Low Vitamin D in Mongolia, supplementing would save lives (20 percent have rickets) – Oct 2019
• Rickets – 1 in 10,000 in Canada and UK, 1 in 2 in Russia and Mongolia
