title: GENEActiv accelerometer files collected in Vanuatu during FALAH project (non-anonymized version - second part)

description: GENEActiv accelerometer .bin files recorded in Vanuatu during FALAH project. Devices are 60-Hz triaxial accelerometers.

Participant characteristics: 13 to 17 years old students.

Number of participants: 72.

Year of the study: 2023.

Place of the study: Vanuatu.

The accelerometer .csv and .RData files with a 1 second epoch and extracted from raw .bin files are available in the restricted datasets:



anonymized version (first part)

anonymized version (second part)


The anonymized datasets also contain participantCharacteristics.csv that povides basic information about participants and read_a_binFile_share.R that is a short R code aiming at converting and saving accelerometer data from .bin files in 1 second epoch .csv files (consider the Methods section).

The accelerometer raw .bin files are available in the restricted datasets:



non-anonymized version (first part)

non-anonymized version (second part)


Other participant characteristics (age, place of living, ...) and responses to questionnaires are available in a restricted non-anonymized dataset.
description: Consent

Before the study, parents were informed about the research project and the study through the home liaison diary. They were aware that they could opt out their children from the study. Similarly, each child / adolescent could signal their refusal or opt out himself / herself at any time (i.e. before, during and after the class intervention) simply by indicating it to the research team.

These data were collected during the European Family farming, lifestyle and health in the Pacific (FALAH) project. The project was first approved by the consultative Ethics committee of New Caledonia (2018-06 001 and 2023-10 012) and the Vanuatu Ministry Of Education and Training. The targeted schools were contacted, and the project was then proposed to the administrative (school Principal) and teaching teams for their acceptance.

Data collection

Data were collected from the 13rd June to 3rd July 2023, from 224 school-going adolescents (13 - 19 years old) during class time. In each school, four classes were chosen to respond to the anonymous questionnaire, which consisted of two parts lasting 45 to 50 minutes each and was carried out in two stages.

About 30 to 40 participants (according to the number of devices available) per school were randomly selected to wear a GENEActiv accelerometer device for 5 to 7 consecutive days, or more. Consenting participants were asked the device for 7 days. When a participant refused to wear the device, another random draw was made. A total of 73 adolescents accepted to wear an accelerometer device.

Data readability, validity and conversion

We were not able to get data from 1 adolescent device because of device or record failure.

Raw data files are readable with common software libraries, like the R package GENEAread as well as with the GENEActiv software.
description: Description of the files

.bin files were collected with GENEActiv accelerometer device and were extracted with the GENEActiv software. Each file is associated to a participant who wore the device for 5 to 7 consecutive days.
