Whether joint leisure time physical activity and dietary quality alleviates metabolic syndrome and its components: evidence from the National Health and Nutrition Examination Survey (2007-2018).
Article in PloS one, 2025. 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
objectivesThe incidence of metabolic syndrome (MetS) is increasing, which is one of the major threats to human health. Whether joint leisure time physical activity (LTPA) and dietary quality (DQ) can reduce the risk of developing MetS and its components is worth exploring. Therefore, this study aimed to investigate the individual and combined effects of LTPA and DQ on MetS and its components.
methodsData were extracted from the National Health and Nutrition Examination Survey from 2007 to 2018. LTPA was classified as inactive, insufficiently active (IA), weekend warrior (WW), and regular active (RA); DQ was categorized as high dietary quality (HDQ) and low dietary quality (LDQ). Afterwards, population characteristics of MetS were analyzed. Then, univariate and multivariate logistic regression were used to analyze individual and combined effects of LTPA and DQ on MetS and its components. Subgroup analysis and restricted cubic spline (RCS) were used to examine the robustness and non-linearity.
resultsThis study included 31,482 adults aged 20 or older. Results showed that RA, HDQ and RA&HDQ were significantly negatively correlated with MetS and its components. IA&HDQ was significantly and negatively correlated with MetS, waist circumference and high-density lipoprotein cholesterol. WW&HDQ was not significantly associated with MetS, but was significantly negatively linked to fasting glucose and blood pressure. No significant interaction effect was observed in subgroup analysis. RCS analysis revealed a significant non-linear negative correlation between LTPA and MetS.
conclusionsThis research indicates that RA and HDQ alone or in combination are associated with a lower risk of developing MetS and its components and could serve as effective preventive and therapeutic strategies against MetS and its associated risk factors. The decline in MetS risk become even more significant after exercise for 500 min/week. Similar trends are observed among fasting glucose, blood pressure, and triglyceride levels.
