Using Mid-Upper Arm Circumference z-score (MUACz) tapes for community-based assessment and monitoring of nutrition risks among young children: a qualitative analysis of experiences and lessons from southwest 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 1 paper.
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
objectives and studyIn 2023, Community Health Volunteers (CHVs) and the Ministry of Health (MOH) staff were trained to use the novel MUAC z-score (MUACz) tape for household anthropometric measurements in southwestern Kenya as part of a randomized controlled trial titled ALIMUS-We are Feeding! In this qualitative study, we aimed to understand the experiences and lessons learned from using the MUACz tape for screening and monitoring among health professionals.
methodsIn this qualitative study, Focus Group Discussions (FGDs) were used to explore the experiences of CHVs and MOH staff, who were trained on using the MUACz tape and applied the device for nutrition screening among 617 children aged between 23 and 59 months. Two FGDs were conducted with CHVs (n = 14) and one with MOH staff (n = 7). Trained facilitators led discussions using a semi-structured interview guide in Dholuo and Swahili. FGDs were recorded, transcribed, translated, and analyzed using thematic analysis.
resultsBroad emerging themes showed that intensive training is essential for learning to use the MUACz tape. Trainings should be in an open learning environment, using simple language and incorporating hands-on practice. Participants had positive experiences using the MUACz tape, appreciating the expanded age, risk and color-coding categories. Challenges in using the tape included durability and the font size of tape markings. Participants emphasized the importance of integrating MUACz tape in existing CHV tool kits and data collection, in addition to adding z-score as an indicator in the health care database and services to ensure consistency and sustainability.
conclusionsThe findings highlight that a few improvements of MUACz tapes could facilitate community-based nutrition screening and monitoring. Frontline community health workers play a critical role in shaping the implementation of public health programs. Accessible training is important for their buy-in.
