Molar pregnancy and husband's occupation: do soil and dust have any role?

This case-control study investigated the association between molar pregnancy and husband's work. In the analysis, cases were 30 women with complete mole and controls were 30 matched women with term pregnancies. The husband's of cases were more likely to have occupations involving physical work than non-physical work and this physical work more usually involved exposure to soil and dust. Among all occupations, the husband's of cases were more likely to have occupations which had exposure to soil and dust (P < 0.01). Comparing all occupations that had exposure to soil and dust with all those who did not have this exposure (physical and non-physical) resulted in a statistically significant difference in the occurrence of molar pregnancy (P < 0.001).
