The PERUSANO study: questionnaire for quantitative survey

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 collected in the questionnaire include : - Section 0: Screening questionnaire for main survey and consent - Section 1: Participant information - Section 2: Household roster - Section 3: Socio-demographic questionnaire - Section 4: Infant health and infant feeding practices - Section 5: Maternal diet and nutrition knowledge - Section 6: Haemoglobin measurements for the mother and child - Section 7: Weight and height measurements for the mother and child <br> The corresponding datasets and data dictionaries are available at 10.17028/rd.lboro.16691455 and 10.17028/rd.lboro.21656348. <br> <br> <br> <br> <br>
