Background: Maternal passive smoking and vitamin D deficiency might elevate risk of spontaneous abortion. The study aimed to investigate the association of co-exposure to passive smoking and vitamin D deficiency with the risk of spontaneous abortion.
Methods: A population-based case-control study was performed among non-smoking women in Henan Province, China, with 293 spontaneous abortion cases and 496 liveborn controls with term, normal birthweight.
Results: Compared to women without exposure to passive smoking nor vitamin D deficiency, women with deficient vitamin D alone and women with exposure to passive smoking alone had increased risk of spontaneous abortion (OR = 1.76, 95%CI: 1.08~2.89; OR = 1.73, 95%CI: 1.11~2.69, respectively).
The risk of spontaneous abortion was even higher for those with co-exposure to passive smoking and vitamin D deficiency (OR = 2.50, 95%CI: 1.63~3.84). A dose-response relationship was found of an incremental risk of spontaneous abortion with rising numbers of exposures to passive smoking and vitamin D deficiency (p < 0.001).
Conclusion: Co-exposure to passive smoking and vitamin D deficiency was associated with an elevated risk of spontaneous abortion, and the risk of spontaneous abortion rose with rising numbers of exposures. Intervention programs need to specifically target the vulnerable groups of pregnant women with both malnutrition and unfavorable environmental exposure.

VitaminDWiki - Smoking reduces vitamin D - many studies contains
Two pathways are often proposed for how smoking decreases vitamin D:
1) Smoking decreases Calcium. and Vitamin D is used up in replacing the Calcium
2) Smoking injures the body, and vitamin D is used up in repairing the body
It appears that taking Vitamin D while smoking will:
1) Decrease the incidence of the many health problems associated with smoking - even lung cancer
2) Decrease the desire to smoke (perhaps take fewer smoking breaks?)
3) Increase breathing capacity
Opinion: If you must smoke, have recently smoked, or are getting 2nd hand smoke:
take Vitamin D and perhaps Omega-3
They will extinguish much of the inflammation caused by inhaling tobacco smoke.
Vitamin D should also help people quit smoking See bottom of page Smoking reduces vitamin D - many studies
