Obesity, Childhood Health Behavior Physical Activity Dietary Habits | Behavioral: Intervention Program to Promote Healthy Eating and Physical Activity among Palestinian Female Schoolchildren | Not Applicable |
A randomized controlled intervention program trial was carried out in 14 females' schools in East Jerusalem, selected randomly by a stratified sampling of four groups of schools. The primary target population was the students, while the secondary target populations were the mothers and the teachers at these schools. From the schools operating in East Jerusalem (Palestinian Authority, Jerusalem Municipality, private, and United Nations Relief and Works Agency) grades 4 and 5 were considered eligible to participate in the pre- and post-intervention studies.
The study process was designed, using the ecological model, in three stages; Stage one: Need assessment stage (pre-intervention, March-Jun 2011): A semi-structured interview was used with all 14 school principals, and a structured self-administered questionnaire was used with all teachers. A random sample of a 4th and 5th grade classes was selected, in which all mothers and their daughters were eligible to answer a self-administered questionnaire. The height and weight of the children were measured during this stage. These measurements were the baseline for assessing the current situation. In addition to school inspection tours was done to assess the school's health environment.
Stage two: Action stage (intervention, September 2011-June 2013): A random allocation of schools into intervention and control groups was done, followed by participatory planning and administration of the intervention in each of the 7 schools based on their needs assessments and assets. The program was implemented and administered by a steering committee in each of the schools, consisting of teachers, mothers, and children. Teachers underwent trainings in nutrition and physical activity. The program activities were monitored by regular visits twice a month. The implementation team met every four to six weeks to review the progress.
Stage three: Evaluation (post intervention, February-April 2013): Evaluation of the program was done after eighteen months of intervention using the same assessment questionnaires for both intervention and control schools among a different sample of children from grades 4 and 5, their mothers, and all of the teachers.
