Food and Nutrition Insecurity: Experiences That Differ for Some and Independently Predict Diet-Related Disease, Los Angeles County, 2022.

BACKGROUND: National surveillance shows that food insecurity affects ≥1 in 10 Americans each year. Recently, experts have advocated for surveillance of nutrition and food insecurity. Nutrition security refers to the nutritional adequacy of accessible food and factors that impact one's ability to meet food preferences. OBJECTIVES: This study presents representative estimates of food insecurity and nutrition insecurity for Los Angeles County, CA, United States; compares predictors of these constructs; and examines whether they independently predict diet-related health outcomes. METHODS: In December 2022, a representative sample of Los Angeles County adults participating in the Understanding America Study (N = 1071) was surveyed about household food insecurity and nutrition insecurity over the past 12 mo. Data were analyzed in 2023. RESULTS: Reported rates were similar for food insecurity (24%) and nutrition insecurity (25%), but the overlap of these subgroups was <60%. Logistic regression models indicated that non-Hispanic Asian individuals had higher odds of nutrition insecurity but not food insecurity. Moreover, nutrition insecurity was a stronger predictor of diabetes compared with food insecurity, and both constructs independently predicted poor mental health. CONCLUSIONS: Food and nutrition insecurity affect somewhat different populations. Both constructs are valuable predictors of diet-related health outcomes. Monitoring nutrition insecurity in addition to food insecurity can provide new information about populations with barriers to healthy diets.

Lost support, lost skills: Children's cognitive outcomes following grandparental death.

OBJECTIVE: This study examines the implications of grandparental death for cognitive skills in middle childhood. METHOD: This study uses data from the Future of Families and Child Wellbeing Study (N = 2479) to estimate ordinary least squares regression models of the associations between grandparental death and subsequent cognitive skills among children in middle childhood. RESULTS: Experiencing a grandparental death between ages 5 and 9 is associated with boys' lower reading, verbal, and math scores at age 9, with associations most notable for Black and Hispanic boys; grandparental death before age 5 has minimal influence on boys' cognitive skills at age 9. There is little indication that grandparental death adversely affects girls' cognitive skills. CONCLUSION: The numerous and persistent implications of grandparental death for boys' cognitive skills merit greater recognition of grandparental death as a source of family instability, stress, and ultimately inequality in child development.

New insights into grocery store visits among east Los Angeles residents using mobility data.

In this study, we employed spatially aggregated population mobility data, generated from mobile phone locations in 2021, to investigate patterns of grocery store visits among residents east and northeast of Downtown Los Angeles, in which 60% of the census tracts had previously been designated as "food deserts". Further, we examined whether the store visits varied with neighborhood sociodemographics and grocery store accessibility. We found that residents averaged 0.4 trips to grocery stores per week, with only 13% of these visits within home census tracts, and 40% within home and neighboring census tracts. The mean distance from home to grocery stores was 2.2 miles. We found that people visited grocery stores more frequently when they lived in neighborhoods with higher percentages of Hispanics/Latinos, renters and foreign-born residents, and a greater number of grocery stores. This research highlights the utility of mobility data in elucidating grocery store use, and factors that may facilitate or be a barrier to store access. The results point to limitations of using geographically constrained metrics of food access like food deserts.

The gendered relationship between maternal depression and adolescent internalizing symptoms.

It is well-established that adolescents whose mothers are depressed are themselves more likely to experience internalizing symptoms (e.g., depressive and anxiety symptoms). Even as extensive work shows that internalizing symptoms are more prevalent among adolescent girls compared to boys, it is unclear if the maternal-offspring mental health relationship is gender-neutral or gender-specific: Does maternal depression act as an equalizing force for adolescents' risk of internalizing symptoms, or does it contribute to adolescent gender differences? This study analyzes whether adolescent gender moderates the association between maternal depression and adolescent internalizing symptoms using data from the Year-15 survey of the Fragile Families and Child Wellbeing Study, which follows a cohort of children born in large U.S. cities, primarily to unmarried parents. This sample of 2159 primary caregiver mothers and adolescent offspring (ages 14-18 years) has numerous social risk factors for internalizing symptoms, affording the opportunity to carefully assess the possibly gendered nature of mother-adolescent linkages. Adjusted ordinary least squares regression models showed that maternal depression is associated with significantly higher adolescent depressive and anxiety symptoms. However, the relationship between maternal depression and adolescent internalizing symptoms is substantially larger for daughters compared to sons. The gendered nature of these concurrent mother-adolescent symptoms highlights the need to consider the effect of gender on other risk processes within families. Moreover, the strong clustering of internalizing symptoms among mothers and daughters highlights the value of prevention and treatment efforts that attend to adult and adolescent mental health simultaneously.
