Age refers to chronological age of a subject when the outcome of interest occurs, and period the corresponding calendar date. Cohort refers to the year of birth, which identifies a generation, but this may be calculated by taking the difference between age and period, which can make these ...
In this tutorial, we will use a simulalated data based on a nationally representative dataset in Australia and disentangle changes in cannabis use trends into age, period and cohort effect. The challenge of age-period-cohort analysis (APC analysis) has long been identified because thecohortvariabl...
Obesity is a growing problem worldwide and can often result in a variety of negative health outcomes. In this study we aim to apply partial least squares (PLS) methodology to estimate the separate effects of age, period and cohort on the trends in obesit
PURPOSE: South Korea has the highest incidence rate of thyroid cancer in the world, and the incidence rate continues to increase. The aim of this study was to determine the age-period-cohort effects on the incidence of thyroid cancer in Korea. MATERIALS AND METHODS: Using the Korean National...

In such analysis, period effects may capture mainly the effects on breast cancer death rates of factors related to improved survival such as screening and adjuvant therapy, whereas cohort effects may give some clues of risk factors changing the incidence of the disease. The aim of this paper is...
Age-Period-Cohort Analysis: New Models, Methods, and Empirical Applications is based on a decade of the authors' collaborative work in age-period-cohort (APC) analysis. Within a single, consistent HAPC-GLMM statistical modeling framework, the authors synthesize APC models and methods for three re...
The aim of APC analysis is to assess the contributions of age, period and cohort effects on the outcome such as demographic or disease rates. The age effects represent a differing risk of the outcome associated with different age brackets; the period effects represent variations in the outcome ...
