"If the college adjusted the prices ": comparing food secure and insecure college students during the COVID-19 pandemic.

Objective: We examined how students' food insecurity related to their demographic information, academic experiences, use of food programs, and reflections on food during the COVID-19 pandemic. Participants: 246 NYC undergraduates during the first 9 months of the pandemic. Methods: Students reported on food insecurity (eg, USDA's 10-item AFSSM), household income, impact of food insecurity on academics, GPA, and use of food programs. They wrote two food narratives. Results: 135 (54.88%) participants reported high food security; 51 (20.73%) reported low or very low food security. Compared to high food security students, low and very low-security students were more likely to identify as Black and first-generation immigrants, reported lower household income, more frequently used food programs, had a lower GPA, reported more academic difficulties, and wrote more often about financial and programmatic difficulties related to food. Conclusions: Food-insecure students need greater financial, academic, and programmatic support during public health crises.

Independent association of serum vitamin D with anti-Mullerian hormone levels in women with polycystic ovary syndrome.

OBJECTIVE: This study aimed at investigating the association of serum vitamin D (25(OH)D) and anti-Mullerian hormone (AMH) levels in women with polycystic ovary syndrome (PCOS) as well as non-PCOS healthy ovulatory women and the possible confounding effects of adiposity and androgen. METHOD: This was a cross-sectional study conducted on serum samples collected from 451 women diagnosed with PCOS as well as 244 age-matched healthy ovulatory women in a tertiary gynaecology out-patient clinic and a family planning clinic. RESULTS: Serum 25(OH)D level was significantly higher in women recruited during summer and autumn than those recruited in winter and spring. Both serum 25(OH)D and AMH levels peaked during summer in women with PCOS. In ovulatory women, only serum 25(OH)D but not AMH level showed such seasonal variation. Serum 25(OH)D level in women with PCOS significantly correlated positively with AMH, AMH/antral follicle count (AFC) ratio, serum total testosterone, sex-hormone-binding globulin and quantitative insulin-sensitivity check index and inversely with body mass index (BMI), insulin, triglycerides and homeostatic model assessment of insulin resistance. After controlling for BMI, 25(OH)D level remained significantly correlated positively with serum AMH, AMH/AFC and total testosterone, and inversely with triglycerides. 25(OH)D level was an independent predictor of serum AMH level after controlling for age, BMI and free androgen index in women with PCOS. CONCLUSION: Serum 25(OH)D level is an independent factor significantly associated with AMH level in women with PCOS but not in ovulatory women.
