The PERUSANO study: quantitative dataset

The PERUSANO cross-sectional quantitative survey was conducted amongst low-income mothers and their infants in Peru, from December 2019 to March 2020. This survey is part of a wider interdisciplinary project that aims to address multiple forms of malnutrition in Peru. <br> The study took place in two peri-urban areas: Manchay in Lima and Huánuco district in the Andean highlands (~ 1900m above sea level). <br> In each study area, we purposively selected the principal health centre and one subsidiary health centre. Peri-urban communities under the jurisdiction of these health centres were then selected to participate. A purposive quota sampling was employed to recruit mothers with children aged 6-23 months, with equal numbers across age groups (6-11, 12-17 and 18-23 months) and study site (Manchay/Huánuco district). The target sample size was 360 mother-infant dyads. Recruitment stopped in March 2020 due to the COVID-19 pandemic, at which point 244 mother-infant dyads had been recruited and no further recruitment took place. Additional information on sampling can be found elsewhere (Pradeilles et al., 2022). <br> Data in the dataset (English only) include household socio-demographic characteristics, maternal and infant 24-hour dietary recalls, maternal 7-day food frequency questionnaire, maternal nutrition knowledge, maternal and infant supplement intake including iron, maternal anthropometry (height, weight and waist circumference) and child anthropometry (length or height and weight), morbidity and maternal and infant haemoglobin concentration. A dictionary of variables is also available in English only. <br> The survey questionnaire is available in English and Spanish language at 10.17028/rd.lboro.18750458. <br> Food consumption and nutrient data for infants and young children are available at 10.17028/rd.lboro.21656348. <br>
