Aim: To objectively assess physical activity (PA) and body size in 6-year-old children and their mothers participating in the Pacific Islands Families (PIF) cohort study, and to identify factors potentially related to PA and body size in Pacific children.
Methods: The PIF cohort was drawn from live births at Middlemore Hospital (South Auckland, New Zealand) in 2000. Information has been collected at birth, 6 weeks, 12 and 24 months, and 4 and 6 years postpartum. At 6 years, the Child and Parental Physical Activity and Body Size (PIF:PAC) study was simultaneously conducted and measures of child and mother PA (8-day accelerometry), body size (waist circumference, body mass index), and PA supports and barriers (questionnaire) taken.
Results: 254 mothers and their children took part in the PIF:PAC study. Usable accelerometer data were gathered for 173 mothers and 199 children over an average of 3-4 days. High levels of overweight and obesity were found in boys, girls, and mothers (62%, 58%, and 97% overweight or obese, respectively).
Conclusion: Strategies for obesity reduction in Pacific populations are urgently required. Combined, the PIF and PIF:PAC studies will provide vital information for understanding and targeting the obesity epidemic in Pacific children.
