Beyond poverty, tungiasis is associated with family characteristics and parenting behavior: a case control study in Kenya.
Article in BMC public health, 2026. 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
backgroundTungiasis is a neglected tropical skin disease caused by the sand flea Tunga penetrans. Female fleas burrow into the skin, typically of the feet, producing inflammation, pain, and itching. Although poverty is a major risk factor, not all households or children in the lowest economic bracket are affected, and boys appear disproportionately infected. This study investigated environmental and behavioral characteristics of households and children to explain these variations.
methodsA total of 3,871 pupils (equal numbers of boys and girls) aged 8-14 years from 44 primary schools in Kwale and Siaya counties, Kenya, were examined for tungiasis. In each school, infected and uninfected pupils were randomly selected for household observations and caregiver interviews. Overall, 273 cases and 548 controls were enrolled, from whom 198 infected and 199 uninfected pupils were selected for in-depth interviews. Mixed-effects logistic regression was used to identify risk factors at individual and household levels. Separate models were run for Kwale and Siaya due to contextual differences, and for boys and girls to explore sex-specific determinants.
resultsAt household level, tungiasis was associated with higher odds in Muslim households in Kwale (aOR 2.44, 95% CI 1.28-4.62) and traditionist households in Siaya (aOR 2.27, 95% CI 1.06-4.86) compared to Christian households. Additional risk factors included having a male caregiver (Kwale: aOR 2.31, 95% CI 1.02-5.23), a child with disabilities (Siaya: aOR 7.19, 95% CI 1.64-31.65), and lack of caregiver involvement in schoolwork (Siaya: aOR 1.90, 95% CI 1.13-3.19). For girls, infection odds were higher if parents rarely attended school meetings (aOR 2.11, 95% CI 1.00-4.44) or when mothers were frequently absent (aOR 2.46, 95% CI 1.07-5.64). Caregiver stress scores were positively associated with infection risk across sexes (aOR 1.03, 95% CI 1.00-1.06).
conclusionThis study identifies novel risk factors for tungiasis beyond poverty, including caregiver characteristics, psychosocial stress, and parenting practices. Effective control interventions should integrate psychosocial support for caregivers and promote positive parenting alongside traditional One Health prevention and treatment strategies.
