This study examined the relationships between food insecurity, mental health, and academic performance among college students in a California public university system (N = 8705). Structural equation modeling was performed to examine a direct path from food insecurity to student grade point average and an indirect path through mental health, controlling for demographic characteristics. Food insecurity was related to lower student grade point average directly and indirectly through poor mental health. These findings support the need for future interventions and policy on the importance of providing students with the basic needs to succeed both academically and in the future.

Accumulating evidence suggests that food insecurity in US colleges and universities is higher than in US households, making this a new public health priority. We conducted a systematic review of food insecurity among US students attending higher education institutions. A total of eight studies met inclusion criteria, representing data from 52,085 students. Unweighted mean food insecurity prevalence among this sample was 43.5% (SD = 12.4), significantly higher than the 13% reported for US national households in 2015. Higher education institutions must critically examine the problem of food insecurity and take creative policy and programmatic steps to mitigate its consequences. Short-term emergency solutions, such as food pantries, may be useful, but upstream solutions to address basic needs are imperative.

Food insecurity among college students has become a public health concern, yet few studies have examined the sample prevalence in a statewide public university system. We determined the sample prevalence of food insecurity and associated factors among students in a large California university system. In Spring 2015, a sample of graduate and undergraduate students (n = 8705) at 10 University of California campuses completed an online survey of demographic information and a range of student life–related factors, including food access and food security. The majority of participants were undergraduates age 18–24 years; 67% were female. Forty percent experienced food insecurity (42% when weighted). Age, race and ethnicity, childhood food insecurity, and receiving financial aid were risk factors for food insecurity. Food insecure students were more likely than food secure students to face difficulties including insufficient money to purchase food, eating unhealthy food, experiencing food access barriers, difficulty concentrating, and lower academic performance. Food insecurity was high among college students in a California public university system and was associated with factors that may be used to identify students at risk for food insecurity who may benefit from additional information and resources. These findings also provide empirical support to strengthen support systems.

Parental feeding practices are thought to influence children’s weight status, through children’s eating behavior and nutritional intake. However, because most studies have been cross-sectional, the direction of influence is unclear. Moreover, although obesity rates are high among Latino children, few studies of parental feeding practices have focused on this population. This 2-year longitudinal study examined mutual influences over time between parental feeding practices and children’s weight status, in Mexican American families with children 18 years old at baseline. Mothers (n = 322) and fathers (n = 182) reported on their feeding practices at baseline, 1-year follow-up, and 2-year follow-up. Weight status, defined by waist-height ratio (WHtR) and body mass index (BMI), was ascertained at all assessments. Cross-lagged panel models were used to examine the mutual influences of parental feeding practices and child weight status over time, controlling for covariates. Both mothers’ and fathers’ restriction of food predicted higher subsequent child weight status at Year 1, and for fathers this effect was also found at Year 2. Mothers’ and fathers’ pressure to eat predicted lower weight status among boys, but not girls, at Year 1. Child weight status also predicted some parental feeding practices: boys’ heavier weight predicted mothers’ less pressure to eat at Year 1, less use of food to control behavior at Year 2, and greater restriction at Year 2; and girls’ heavier weight at Year 1 predicted fathers’ less pressure to eat and less positive involvement in child eating at Year 2. This study provides longitudinal evidence that some parental feeding practices influence Mexican American children’s weight status, and that children’s weight status also influences some parental feeding practices. Feeding practices of both mothers and fathers were related to children’s weight status, underscoring the importance of including fathers in research on parental feeding practices and child obesity.

The prevalence of food insecurity (FI) among college students is alarmingly high, yet the impact on student health has not been well investigated. The aim of the current study was to examine the simultaneous relationships between food insecurity and health-related outcomes including body mass index (BMI) and overall health in a college student population. Randomly sampled students in the University of California 10 campus system were invited to participate in an online survey in spring 2015. The analytic sample size was 8705 graduate and undergraduate students. Data were collected on FI in the past year, daily servings of fruits and vegetables (FV), number of days in the past week of enough sleep and moderate- to vigorous-intensity physical activity (MVPA), height and weight, self-rated health, and student characteristics. Using path analysis, mediated pathways between FI, BMI, and poor health were examined through FV intake, number of days of MVPA and enough sleep. Analyses controlled for student characteristics. Mean BMI was 23.6 kg/m2 (SD, 5.0), and average self-rated health was good. FI was directly and indirectly related to higher BMI and poor health through three pathways. First, FI was related to fewer days of enough sleep, which in turn was related to increased BMI and poor health. Second, FI was related to fewer days of MVPA, which in turn was related to increased BMI and poor health. Third, FI was related to fewer daily servings of FV, which in turn was related to poor health. FI is associated with poor health behaviors among college students, which may contribute to higher weight status and poor health. These findings highlight the importance of food security for a healthy college experience.

Purpose: A student-specific definition of basic needs for higher education is warranted to inform programs and policies for underserved students. The purpose of this study was to: 1) explore how students define basic needs, 2) understand experiences of housing insecurity, and 3) understand experiences of food insecurity within the context of housing insecurity. Design: Qualitative research elicited student perceptions of basic needs and experiences of housing and food insecurity. Setting: Focus group discussions were conducted at 5 University of California campuses between February and March 2019. Participants: Undergraduate (n = 37) and graduate (n = 21) students were recruited from campus basic needs centers. Methods: Each student completed a brief survey. Researchers conducted 11 focus groups using a semi-structured interview guide. Transcripts were coded to identify themes. Results: Students were female (76%), age 23.6 (SD = 5.8) years; 46% were Pell grant recipients; and 52% were first-generation college students. Most had experienced food insecurity (98%) and 26% had experienced homelessness. Eight themes were identified: 1) students define basic needs as more than minimal food and shelter and as the responsibility of students and the university, 2) students encounter multifaceted housing insecurity issues, 3) affording rent is a priority that most often leads to experiencing food insecurity, 4) transportation barriers interfere with meeting students’ basic needs to succeed as students, 5) students with nontraditional characteristics, graduate students, and out-of-state students face unique challenges in meeting basic needs, 6) limited financial aid and lack of financial aid guidance are barriers to meeting basic needs, 7) fees contribute additional challenges to students meeting basic needs, and 8) additional university basic needs services are essential. Conclusion: A student-informed definition of basic needs included food, housing, mental health, sleep, hygiene, and transportation. This understanding of basic needs can inform future research, programs, and policy to address housing insecurity in higher education.
