Assessing nutrition security and its risk factors using the National Household Food Acquisition and Purchase Survey data.
Article in Public health nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo estimate the prevalence of nutrition security and examine its association with community food environment factors, including food access and affordability.
designThis cross-sectional study used data from the 2012-2013 National Household Food Acquisition and Purchase Survey, including its restricted-use Geography Component (FoodAPS-GC). Household nutrition security measure was derived by combining self-assessed food security and self-rated diet quality indicators into four categories: food secure with high diet quality (FSHD), food secure with low diet quality (FSLD), food insecure with high diet quality (FIHD) and food insecure with low diet quality (FILD). Only FSHD households were considered nutrition secure. Multinomial logit analysis identified factors associated with nutrition security.
participants4685 households with primary respondents aged 20 years or older.
settingNationally representative sample of US households.
resultsApproximately 31·0 % of households were classified as nutrition insecure, including 15·0 % as FSLD, 9·3 % as FIHD and 6·7 % as FILD. The remaining 69·0 % were nutrition secure (FSHD). Nutrition insecurity was significantly associated with younger age, lower educational attainment, lower income, obesity, smoking and poorer self-rated health. Food environment factors, including low geographic access to food and higher local food prices, were not significantly associated with nutrition security. Relying on someone else's car to reach a primary food store was linked to higher odds of nutrition insecurity.
conclusionsThe proposed nutrition security measure can be used to monitor nutrition security in national surveys. Comprehensive measures of the food environment are needed to understand its relationship with nutrition security and to guide targeted policy interventions.
