The PERUSANO study: food consumption and nutrient datasets for infants and young children (6-23m)

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. 

The study took place in two peri-urban areas:  Manchay in Lima and Huánuco district in the Andean highlands (~ 1900m above sea level). 

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).

Data in the dataset (English only) include a food consumption dataset (long format) and nutrient dataset (wide format) for n=242 infants and young children. A dictionary of variables is available in English only for both datasets. A protocol describing the data collection, management and calculation of dietary/nutrient intakes is also available.

The survey questionnaire is available in English and Spanish language at 10.17028/rd.lboro.18750458. The rest of the survey data is available in English only at 10.17028/rd.lboro.16691455.
