“Ola Tuputupua’e” (Growing Up) Study (Samoa)
The “Ola Tuputupua’e” or (Growing Up) Study is a cohort study that began in 2015 with the recruitment of 319 mother-child pairs from 10 villages across the Samoan island of Upolu. Children were two-four years of age in 2015 and will be followed at two-year intervals into adolescence with the goal of understanding how the household and school environments contribute to obesity risk throughout childhood. In each bi-annual wave of the study participants provide physical measurements (height, weight, blood pressure) and a finger-stick blood sample for the detection of anemia. Mothers complete questionnaires detailing household characteristics (socioeconomic position, household composition, food security), child behaviors (diet and physical activity), and child health. A sub-sample of the cohort also wear accelerometers for seven days to objectively measure physical activity.
Longitudinal assessment of growth, health, and development in the Samoan setting will allow us to determine at what age obesity is established and what factors – from early life into adolescence – may be the most important targets for preventative intervention.
Timeline: This study will be actively recruiting for the second study wave (child age 4-6 years) between May and August 2017.
