Prior to the COVID‐19 pandemic, food insecurity and depression were growing public health concerns among graduate students. Yet, little is known about how COVID‐19‐related stressors exacerbated these health outcomes among graduate students. To address this research gap, this study examined two types of COVID‐19‐related stressors, anticipated concerns about remote learning and challenges interfering with academic and research responsibilities, in relation to food insecurity and depressive symptoms among public university graduate students. Between August and October 2020, 631 graduate students who utilised basic needs services from seven University of California campuses completed an online survey assessing the effects of COVID‐19 on their academic experiences, mental health, and basic needs security. Regression analyses examined associations of COVID‐19‐related concerns and COVID‐19‐related challenges with food insecurity as well as COVID‐19‐related concerns and COVID‐19‐related challenges in relation to depressive symptoms. All four models were adjusted for age, sex, race and ethnicity, campus affiliation, and living with a partner. Models examining food security status as the dependent variable were adjusted for depressive symptoms and vice versa. Graduate students concerned about delayed graduation, post‐graduate employment, isolation from faculty and not having access to healthcare reported higher counts of depressive symptoms. Challenges associated with higher counts of depressive symptoms included caring for family more than usual, spending more time on errands and not paying for utilities in full. Students concerned about accessing healthcare had higher odds of experiencing food insecurity. Challenges associated with food insecurity included spending more time on errands, being unable to afford housing and sending money to family members during the pandemic. Our findings illuminate the pandemic's deleterious consequences on graduate students' mental health and food security, underscoring the need for strong academic and basic needs programs and policies.

Evidence for the association between breastfeeding (BF) duration and later body mass index (BMI) is inconsistent. We explored how BF duration and BF type (exclusive or partial) related to BMI from childhood to young adulthood in a Chilean cohort. Infants were recruited at 6 months between 1994 and 1996 in Santiago, Chile (n = 821). Mothers reported date of first bottle and last BF; anthropometry was measured at 1, 5, 10, 16, and 23 years. We tested whether: (1) type of BF at 6 months (none, partial, exclusive) and (2) duration of exclusive BF (<1 month, 1 to <3 months, 3 to <6 months, and ≥6 months) related to BMI. At 6 months, 35% received both breastmilk and formula (“partial BF”) and 38% were exclusively breastfed. We found some evidence of an association between longer BF and lower BMI z-scores at young ages but observed null effects for later BMI. Specifically, BF for 3 to <6 months compared to <1 month related to lower BMI z-scores at 1 and 5 years (both p < 0.05). Our results are in partial accordance with others who have not found a protective effect of longer BF for lower BMI.
