Study title

The pilot study investigated the effectiveness of the 'Let's Move It' programme, which aimed to increase physical activity (PA) and reduce sedentary behaviour (SB) among students in vocational schools in Finland. This dataset consists of the students' responses to several surveys conducted over the study period, the students' body composition measurements, accelerometer data on the students' physical activity, and variables created by the researchers based on original variables. 43 students in total participated in the pilot study. The students were divided into four groups, two of which participated in a variety of intervention measures. The other two groups formed the control group (did not participate in intervention measures). The research was funded by the Ministry of Education and Culture (OKM/81/626/2014) and the Ministry of Social Affairs and Health (201310238). Variables in the data have been named as follows: variables beginning with the letter K are survey responses, letter H indicates accelerometer (Hookie) variables, letter T indicates body composition measurement (TANITA) variables, and letter R indicates variables created by the researchers where values have been reverse coded. Data were collected at four points during the study period: before the implementation of the 'Let's Move It' programme, halfway through the programme, right after the programme ended, and six months after the programme ended. The time point of the data collection is indicated by the numbers 1-4 following the underscore in the survey response variables and by the letters a-c and a mention in the variable label in the accelerometer and body composition measurement variables. Some variables are in Finnish and some in English. The four online questionnaire surveys mainly repeat the same questions. Health status was surveyed with questions on health issues, stress, smoking, eating and sleeping. Other questions charted the amount and kind of physical activity, motivation and...
