Do minimum acceptable diet and family caregiving mediate the associations of maternal education and household wealth with childhood stunting and wasting in Sri Lanka?
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 investigate the extent to which the associations of socio-economic position (SEP) with stunting and wasting are mediated by minimum acceptable diet (MAD) and a family care indicator (FCI) in Sri Lanka.
designSecondary data analysis of children from the 2016 Sri Lanka Demographic and Health Survey. The outcomes were stunting and wasting, the exposure was a composite measure combining maternal education and household wealth, and the mediators were binary MAD and FCI variables (adequate
settingA nationally representative sample of children from Sri Lanka.
participantsMothers/caregivers of children under 36 months (4325).
resultsTwenty per cent of children were stunted, and 14 % were wasted. Lower SEP was associated with higher odds of stunting and wasting and inadequate MAD and FCI. Inadequate FCI was associated with higher odds of stunting (OR = 1·47, 95 % CI = 1·24, 1·74) but not wasting (OR = 1·14, 95 % CI = 0·94, 1·38), whereas MAD was not associated with stunting or wasting. Neither MAD nor FCI significantly mediated the relationship between SEP and stunting and wasting. All mediation estimates were statistically non-significant at the 5 % level. For example, the proportion mediated by FCI on the association between the lowest composite SEP and stunting was 13 % (mean difference = 0·13, 95 % CI = < 0·00, 0·26).
conclusionWe did not find consistent or strong evidence that the associations of SEP with childhood stunting and wasting in Sri Lanka are mediated by MAD and FCI. Research with larger samples is needed for more precise estimates.
