Gender disparity persists in the United States; women are still paid less than men and are also subject to discrimination in the workplace based on the fact that they may become mothers. Further, there is evidence to indicate that single mothers are judged more harshly than their married mother counterparts and single fathers. As a form of amelioration, some women self medicate with alcohol and according to the CDC), alcohol use disorder (AUD) is on the rise for women. Although there is research on gender disparity, the motherhood penalty, and AUD, there are no experiments testing socio-cognitive judgments on those combined factors and specifically examining what we term "the single motherhood penalty". Therefore, in two experiments using between-participants designs, participants rated a picture of a person (female or male) paired with a brief description where marital status (single or married) and type of ailment (alcohol or physical) was manipulated. In Experiment 1, a passive AUD manipulation did not show a clear single motherhood penalty. In Experiment 2, the results of an active AUD manipulation supported the predicted single motherhood penalty (Experiment 2a), but did not show an analogous single fatherhood penalty (Experiment 2 b). These findings are the first to offer empirical evidence that socio-cognitive judgments might perpetuate the interplay of the single motherhood penalty and AUD.

The primary goal of this study was to investigate the effects of sex, oral contraceptive (OC) use, and menstrual cycle phase on common ocular parameters assessed during ophthalmic evaluations, namely intraocular pressure (IOP), central corneal thickness (CCT), and foveal thickness (FT), in young healthy adults. We measured IOP, CCT, and FT in 60 participants (16 men, 16 contraceptive users, and 28 cycling women) over two sessions that characterized the menstrual cycle phase in women. For men in our study, two sessions were separated by two weeks. For women, the two sessions were scheduled during the follicular and luteal phases of the menstrual cycle. There was a trend towards higher IOP in men, and the difference was significant for white, non-Hispanic subjects and for white subjects considered separately. There was also a trend for thicker corneas in women, but men had significantly thicker foveae. CCT and FT were not different between men and OC-users, hinting at a moderating hormonal effect of oral contraceptive use. We found that IOP, CCT, and FT were equivalent between the follicular and luteal phases, which may be owing to the timing of our sessions. However, our findings strongly suggest that clinicians should consider contraceptive use during routine ophthalmic evaluations, as it could inform glaucomatous risk in women.

Purpose: There is robust evidence that higher macular pigment concentrations help reduce both veiling and discomfort glare in patients with or without ocular disease. We investigated whether there was also a relationship between macular pigment optical density (MPOD) and patient surveys about glare or ocular discomfort., Methods: We measured MPOD psychophysically in 23 healthy subjects and administered the National Eye Institute Visual Functioning Questionnaire (VFQ-25). Responses for each survey question were sorted from low (no limitation) to high (very severe limitation). The median response for each question was determined, and independent t-tests were performed on the mean MPOD values for survey responses above and below the median. We also performed a non-parametric correlation analysis between MPOD and survey responses., Results: While the median response was "no limitation" for most (22 of 25) survey questions, responses were slightly higher for two questions concerning ocular discomfort and one question related to driving at night. MPOD levels were significantly higher in subjects that reported no discomfort in or around their eyes than in those that reported mild discomfort. There was also a trend toward higher MPOD levels in subjects who reported that pain in or around their eyes never limited their activity as well as in subjects who reported no difficulty driving at night., Conclusion: These preliminary findings are consistent with the well-established discomfort and glare hypotheses for MPOD. The current findings on subjective ocular discomfort in the absence of glare deserve further study., (Copyright © 2020 Spanish General Council of Optometry. Published by Elsevier España, S.L.U.
