title: Associations of Socioeconomic Status with Diet and Physical Activity in Migrant Bougainvilleans in Port Moresby, Papua New Guinea.
abstract: Urban migrants in Papua New Guinea have undergone a nutritional transition. The present study investigated associations of socioeconomic status with dietary and physical activity patterns among migrant Bougainvilleans from Nassioi territory in the capital city of Port Moresby, Papua New Guinea. All adults Naasioi migrants residing in Port Moresby were identified (N = 185) and 70 were included. The International Physical Activity Questionnaire was used to evaluate physical activity, and dietary patterns were assessed by per-week consumption frequency of food items. Principal component analysis was applied to produce a composite score for socioeconomic status. Least square regression analysis indicated that socioeconomic status was positively correlated with consumption of a traditional diet (p = .03) and negatively with walking-related physical activity (p = .02), but it was not correlated with MET-minutes of moderate/vigorous activity. Different patterns of nutritional transition occur among migrants in urban Papua New Guinea, depending on socioeconomic status.
