Abstract [en]

Adverse reactions to ambient odorous and pungent substances in daily activities among pregnant women who are half-way through pregnancy, and changes in odor perception at predominantly an early stage of pregnancy motivated the present study of odor intolerance at an early pregnancy stage. Ninety-five women averaging gestational week 11 and 102 non-pregnant women were compared with the Chemical Sensitivity Scale for Sensory Hyperreactivity (CSS-SHR). General environmental intolerance was assessed with items from the Noise Sensitivity Scale that are analogous to the CSS-SHR (“NSS-SHR”). Pregnant women were found to have higher scores on the CSS-SHR, but not on the “NSS-SHR”. This suggests an odor intolerance that affects pregnant women's daily activities, which appears not to be due to a general environmental intolerance. The effect size of pregnancy on CSS-SHR score is larger in the present study of early pregnancy than in the previous study of women half-way through pregnancy.

Abstract [en]

Self-reported abnormal sensitivity, qualitative distortions and phantom sensations with respect to smell and taste was assessed with a longitudinal design, based on questions referring to gestational weeks 13–16 and 31–34 of pregnancy in comparison with 9–12 weeks post partum and with non-pregnant women with corresponding time durations and intervals. The results show that abnormal smell and/or taste perception was reported by 76% of the pregnant women, typically believed to be caused by their pregnancy. Increased smell sensitivity was found to be very common at the early stage of pregnancy (67% of all pregnant respondents) and occasionally accompanied by qualitative smell distortions (17%) and phantom smells (14%). The smell abnormalities were less common at the late pregnancy stage and almost absent post partum. Abnormal taste sensitivity was fairly commonly reported (26%), often described as increased bitter sensitivity and decreased salt sensitivity. These results, suggesting that abnormal smell and/or taste perception is experienced by a large majority of pregnant women, imply that further research is needed to understand to what extent these chemosensory changes may underlie food aversions and craving with implications for food intake during pregnancy.
