Understanding the association of food insecurity and nutrition insecurity with diet quality: a cross-sectional analysis of 2 national samples.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFood insecurity is associated with poor diet quality. However, nutrition security may better predict diet quality as it specifically measures healthy food access.
objectivesThis study aims to examine the associations between food security, nutrition security, and joint food and nutrition security status with diet quality.
methodsData came from 2 cross-sectional surveys of United States adults (n = 4554) and Supplemental Nutrition Assistance Program (SNAP) participants (n = 1463). For United States adults, food security was measured with the 18-item Household Food Security Survey Module, and diet quality was measured with the Prime Diet Quality Score (PDQS). For SNAP adults, food security was measured with the USDA's 6-item Food Security Survey, and diet quality was measured with the rapid PDQS (rPDQS). Nutrition security was measured with the Center for Nutrition and Health Impact's Household Nutrition Security (HNS) in both samples. Linear regression models analyzed the relationship between food and nutrition security and diet quality separately and jointly, adjusting for sociodemographic covariates.
resultsIn the United States adult sample, 52.8% were food and nutrition secure (FS/NS), 16.4% were food insecure and nutrition secure (FI/NS), 4.2% were food secure and nutrition insecure (FS/NI), and 26.6% were food and nutrition insecurity (FI/NI). In the SNAP sample, 24.1% were FS/NS, 27.5% were FI/NS, 1.4% were FS/NI, and 46.9% were FI/NI. After multivariate adjustment, food insecurity was associated with lower diet quality in both samples [United States adults: β = -1.2 PDQS points; 95% confidence interval (CI): = -1.9, -0.54; SNAP sample: β=-0.92 rPDQS points; 95% CI: -1.7, -0.14]. Nutrition insecurity was not associated with lower diet quality for either sample. In both samples, joint food and nutrition insecurity was associated with the lowest diet quality compared with other groups.
conclusionsFurther research is needed to understand the utility of the HNS because food insecurity was more strongly associated with lower diet quality than nutrition insecurity.
