Diabetes incidence and projections from prevalence surveys in Samoa over 1978-2013.

ABSTRACT:

Objectives

This study estimates type 2 diabetes (T2DM) incidence in Samoans aged 25-64 years from sequential, irregularly spaced, cross-sectional population prevalence surveys.

Methods

T2DM prevalence from eight population surveys conducted over 1978-2013 (n = 12,516) was adjusted for census region, sex, and 5-year age group to the nearest previous census. Annual T2DM incidence was calculated from adjusted prevalences (by sex), using birth cohorts constructed from age-period matrices. Projections of T2DM incidence to 2020 were estimated, based on various scenarios of population weight change using Poisson regression.

Results

Over 1978-2013, T2DM incidence was estimated to increase from 1.12 to 8.44 per 1000 person-years in men and from 2.55 to 8.04 per 1000 in women.
