Effect of a postpartum lifestyle intervention among rural women with prior gestational diabetes mellitus from different socioeconomic backgrounds: evidence from a randomized controlled trial in rural China.
Trial report in BMC public health, 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
backgroundLifestyle modification interventions among women with gestational diabetes mellitus (GDM) history have shown to be effective on preventing or delaying the onset of diabetes, however, the differentiating benefits of lifestyle interventions due to socioeconomic inequalities have remained understudied. The Intensive LifeStyle Modification Program (ILSM) was tailored for women with a history of GDM in low-resource rural areas of China. The current study aimed to examine the effect of the ILSM intervention on physiological and behavioral outcomes between subgroups of women from different socioeconomic backgrounds.
methodsThis study used the baseline, 3-month, 6-month, and 18-month data from a cluster randomized controlled trial in rural women with GDM history in Hunan Province of China. The lifestyle program consisted of a combination of in-person group sessions and telephone consultation sessions on dietary intake, physical activity, and stress management. Using generalized estimating equation, we conducted several subgroup analyses based on indicators of socioeconomic status, including age, ethnicity, income, employment, and education.
resultsA total of 320 women were analyzed. The ILSM intervention showed a consistent significance on reducing fasting blood glucose across subgroups. On the contrary, women with full-time employment and high income (≥3000RMB, approximately 425 dollars, per month) were reported to have greater benefits on intentions to eat low-glycemic foods, BMI and waist circumference, and diabetes risk. Women with younger age (≤35 years) or high education (15 years of education or above) were more likely to benefit on improving higher intentions to eat low-glycemic foods and lowering diabetes risk. Interestingly, compared to ethnic majority, ethnic minority women were more likely to increase intentions to eat low-glycemic foods.
conclusionThe ILSM program demonstrated a consistent significance on reducing fasting blood glucose across women from different socioeconomic backgrounds along with an increase of intentions to eat low-glycemic foods for ethnic minority women, despite of showing ineffective in lower socioeconomic status women on intention to have healthy diet, BMI, waist circumference, and diabetes risk. To fully address health disparities from socioeconomic inequalities, lifestyle interventions should be tailored for individuals with older age, lower education levels, and lower income without full-time employment.
