Differences in health-related socioeconomic characteristics among Pacific populations living in Auckland, New Zealand

Abstract

Aim To describe, compare and contrast the health-related socioeconomic characteristics of the different Pacific ethnic groups surveyed in the Auckland Diabetes, Heart and Health Survey (DHHS). Methods The DHHS was carried out in Auckland in 2002–2003. Electoral roll based sampling and cluster sampling strategies were used to recruit a representative sample of Auckland Pacific populations. Participants answered a self-administered questionnaire about their demographic and socioeconomic position. Results The study surveyed 1011 Pacific people aged between 35–74 years of age. Of the 1011 Pacific participants, 484 were of Samoan, 255 Tongan, 116 Cook Island, 109 Niuean, 26 Fijian, and 21 were of ‘Other Pacific’ ethnic groups. Samoans were least likely to have no children, and most likely to hold a certificate qualification. Tongans were least likely to be born in New Zealand (NZ) and had the shortest residence time in NZ. Tongans were most likely to be married and had the largest families. Cook Islanders were most likely to be NZ-born and had the highest household income. Niueans were most likely to be in paid employment, to hold a diploma qualification, to own their own homes, and have the smallest families. Conclusions In conclusion, a distinct pattern (continuum) emerged from the results. The Cook Island and Niuean ethnic groups generally had a similar and more favourable socioeconomic profile compared to the Samoan and Tongan ethnic groups. These differences are most likely to be related to the length of residence in NZ. As differences existed, each Pacific ethnic group should be investigated separately when there are sufficient numbers.
