Objective: Describe experiences of, and responses to, 2022 infant formula shortages among households with infants aged up to 18 months by race/ethnicity using Household Pulse Survey data.
Methods: Outcomes included whether households were affected by shortages and, if so, 3 nonmutually exclusive response categories (increased breastmilk, obtained formula atypically, and disruptive coping [disruptions to breastmilk and/or formula]) and 1 mutually exclusive response category (solely disruptive coping). Unadjusted shares reporting each were compared using t tests.
Accumulating space debris edges the space domain ever closer to cascading Kessler syndrome, a chain reaction of debris generation that could dramatically inhibit the practical use of space. Meanwhile, a growing number of retired satellites, particularly in higher orbits like geostationary orbit, remain nearly functional except for minor but critical malfunctions or fuel depletion. Servicing these ailing satellites and cleaning up "high-value" space debris remains a formidable challenge, but active interception of these targets with autonomous repair and deorbit spacecraft is inching closer toward reality as shown through a variety of rendezvous demonstration missions.

First, we show that receipt of benefits from the Supplemental Nutrition Assistance Program (SNAP) has a systematic effect on responses to questions in the 12-month food security module (FSM). We find that the probability of affirming more severe food hardships items, and the probability of being classified as having very low food security (VLFS), is higher just before and just after households receive their benefits.

Objective: To examine whether skipping breakfast or lunch increased the next meal's energy content and changed total daily energy content and the quality of food intake measured by the 2010 Healthy Eating Index (HEI-2010).
Design: Means were compared across intake days and meal patterns. Multivariate individual fixed-effects model was used to account for individual food intake and diet quality preferences.
From May to November most romaine lettuce shipments in the United States come from California's Central Coast region, whereas from December to April most come from the Yuma, Arizona, region. During 2017-2018, the 3 outbreaks of Shiga toxin-producing (STEC) O157:H7 in US romaine lettuce all occurred at the tail end of a region's production season. During the fall 2018 outbreak, the US Food and Drug Administration (FDA) recommended that suppliers begin labeling romaine packaging so that consumers can identify the product's harvest region.

This study assessed changes in calories and four nutrients (saturated fat, total sugars, sodium, and dietary fiber) from 2012 through 2014 for packaged products frequently consumed by children and adolescents, simulated effects of potential improvements in 12 frequently consumed product categories based on actual purchasing patterns, and compared differences in prices of healthier versus less healthy products. Analysis of trends showed limited evidence that healthfulness of foods improved over the years examined.

Design: Means were compared across survey rounds relative to 2005-06. Multivariate regression was used to account for changes in demographic characteristics over time.
Objective: This study examined the effect of high-fidelity patient simulation (HPS) on dietetics students' self-efficacy before supervised clinical practice.
Methods: This repeated-measures study was conducted during the 2012-2013 academic year. All students in a masters coordinated program cohort (n = 19) participated in an interprofessional HPS experience before clinical supervised practice.
Childhood obesity is associated with a number of serious health risks that can persist into adulthood. While trends in food away from home and fast-food consumption have paralleled trends in childhood obesity, it is important to identify whether this is a causal relationship. This paper reviews recent literature in this area to summarize if there is a consensus in research findings.

Objectives: We compared sugar-sweetened beverage (SSB), alcohol, and other caloric beverage (juice and milk) consumption of Supplemental Nutrition Assistance Program (SNAP) participants with that of low-income nonparticipants.
Methods: We used 1 day of dietary intake data from the 2005-2008 National Health and Nutrition Examination Survey for 4594 adults aged 20 years and older with household income at or below 250% of the federal poverty line. We used bivariate and multivariate methods to compare the probability of consuming and the amount of calories consumed for each beverage type across 3 groups: current SNAP participants, former participants, and nonparticipants.
A censored Exact Affine Stone Index incomplete demand system is estimated for 23 packaged foods and beverages and a numéraire good. Instrumental variables are used to control for endogenous prices. A half-cent per ounce increase in sugar-sweetened beverage prices is predicted to reduce total calories from the 23 foods and beverages but increase sodium and fat intakes as a result of product substitution.

In addition to substitutions that may arise with other beverages, we account for substitutions between SSBs and 12 major food categories. Our main findings are that the tax would result in a decrease in store-bought energy of 24.

Using experimental data from the Mexican conditional cash transfer (CCT) program, Oportunidades, a cross-sectional double-difference estimator on observations from two age cohorts of children is used to identify the impact of early intervention. The results indicate that early health and nutrition interventions can have a positive impact on the timing of enrollment and that caregiver characteristics affect the magnitude of the impact.

Background: Sugar-sweetened beverage (SSB) taxes are increasingly being considered as a strategy for addressing the obesity epidemic. We sought to investigate the differential impact of targeted beverage taxes on higher- and lower-income households.
Methods: This analysis relied on data from the 2006 Nielsen Homescan panel, which included a national sample of households that scan and transmit their store-bought food and beverage purchases weekly for a 12-month period.
The authors studied 2 tasks that placed differing demands on detecting relevant visual information and generating appropriate gaze shifts in adults and children with and without autism. In Experiment 1, participants fixated a cross and needed to make large gaze shifts, but researchers provided explicit instructions about shifting. Children with autism were indistinguishable from comparison groups in this top-down task.

We use panel data from experimental CCT programmes in three Latin American countries to assess the unintended impact of these programmes on childbearing.
