Does food availability affect nutrition-related health among rural residents in China?
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundWith the significant changes in dietary patterns, nutrition-related health issues such as overweight and obesity have become great challenges for public health in emerging economies. However, whether and how food availability could affect nutrition-related health is still unclear.
methodsThe data set comprises 14,505 observations for 8,299 individuals from the 2009-2015 China Health and Nutrition Survey (CHNS) of rural China. Panel regression models with Mundlak (MK) estimators are employed to evaluate the nutritional effect of food availability from five food outlets.
resultsOur findings indicate that the presence, quantity, and density of food outlets have a significant impact on body mass index (BMI) and the likelihood of being overweight. Notably, approximately 39.9% of the probability of being overweight can be attributed to food outlet density, with supermarkets exerting the most substantial influence. Additionally, the food outlet density of free markets and grocery stores has a significantly negative effect on the likelihood of being overweight. To further elucidate the mechanisms through which food availability influences nutritional outcomes, we assess diet quality and dietary knowledge. Our study reveals that food outlet density has a significant effect on the Diet Quality Distance of Dietary Balance Index (DBI-DQD), the Chinese Healthy Eating Index (CHEI), and dietary knowledge.
conclusionThis study reinforces the significant impact of food availability on nutrition-related health. Therefore, policies aimed at effectively improving nutrition-related health in rural China should focus on dynamically adjusting food outlet distribution, particularly supermarkets and grocery stores, enhancing diet quality and nutritional knowledge, and increasing overall food availability in these areas.
