The impact of breast cancer-specific birth cohort effects among younger and older Chinese populations.

Historically low breast cancer incidence rates among Asian women have risen worldwide; purportedly due to the adoption of a "Western" life style among younger generations (i.e., the more recent birth cohorts).

Female breast cancer incidence among Asian and Western populations: more similar than expected.

Background: Previous reports suggested that female breast cancer is associated with earlier ages at onset among Asian than Western populations. However, most studies utilized cross-sectional analyses that may be confounded by calendar-period and/or birth cohort effects. We, therefore, considered a longitudinal (forward-looking) approach adjusted for calendar-period changes and conditioned upon birth cohort.

Sex difference in the incidence of nasopharyngeal carcinoma in Hong Kong 1983-2008: suggestion of a potential protective role of oestrogen.

Background: Nasopharyngeal carcinoma (NPC) shows a male predominance in incidence while the underlying reasons have rarely been explored.

Methods: We analysed incident cases of NPC recorded in Hong Kong Cancer Registry during the period 1983-2008. All cases were divided into 5-year age groups.

Cigarette smoking and changing trends of lung cancer incidence by histological subtype among Chinese male population.

We analyzed the time trends of lung cancer by histological subtype in Hong Kong during 1991-2005, and examined how the time trends were influenced by the effects of birth cohort and calendar period of diagnosis. Cancer incidence data were obtained from Hong Kong Cancer Registry and population data from Census and Statistics Department. Age-standardized incidence rates were computed by the direct method using WHO 1966 standard population as reference.

Time trends of esophageal cancer in Hong Kong: age, period and birth cohort analyses.

This study was to examine the time trend of the incidence rates of esophageal cancer during the period 1979-2003 in Hong Kong and to identify the effects of year of diagnosis (period) and year of birth (cohort) on the observed time trends using regression models. Cancer incidence data were obtained from Hong Kong Cancer Registry and population data were from the Census and Statistics Department. Age-standardized incidence rates were computed by the direct method using the World population of 1966.
