Aims: To compare the distribution of Māori and New Zealand (NZ) European populations in Aotearoa New Zealand by neighbourhood deprivation, for the five censuses between 1991 and 2013, and to identify changes in the distribution pattern over time.

Methods: Geographical meshblock data from the 1991-2013 New Zealand censuses, by NZDep Index deprivation score, and by prioritised ethnic group population, were combined to analyse ethnic population counts by deprivation decile and deprivation score. Trends over time were analysed.

Results: Māori were over-represented in the more deprived NZDep deciles and under-represented in the least deprived deciles for all census periods. The NZ European population were over-represented in the least deprived deciles, and under-represented in the more deprived deciles. In each census, over 40% of the Māori population have been living in the two most deprived deciles, compared to less than 15% for NZ European.

Conclusion: The patterns of inequity in socio-economic deprivation between Māori and NZ Europeans have remained virtually unchanged since 1991, despite various Government commitments to reduce inequity. Socio-economic deprivation for Māori is a key determinant of health inequity, and bolder Government measures prioritised for Māori are needed to change this socio-economic gradient if health equity goals are to be met.

Predicting risk of future dementia is essential for primary prevention strategies, particularly in the era of novel immunotherapies. However, few studies have developed population-level prediction models using existing routine healthcare data. In this longitudinal retrospective cohort study, we predicted incident dementia using primary and secondary care health records at 5, 10 and 13 years in 144 113 Scottish older adults who were dementia-free prior to 1st April 2009.

Purpose: Previous research on pediatric motor vehicle collisions (MVC) and fatalities has primarily focused on patient demographics and crash specific information. This study evaluates whether various measures of local infrastructure, including the National Walk Index (NWI), population density, and public school density, or macroeconomic forces, encapsulated in Social Vulnerability Index (SVI) and food area deprivation (PFA) can predict which counties are most at risk for pediatric traffic fatalities.

Methods: Counties with more than 100,000 children in the most recent US census and ≥1 pediatric traffic fatality as identified in the Fatality Analysis Reporting System (FARS) between 2017 and 2021 were included in the study.

Background: The UK's National Health Service (NHS) is grappling with rising demand and limited dermatologists, leading to longer waiting times. This is particularly concerning for conditions like malignant melanoma, where early diagnosis is crucial. Teledermatology is being introduced to address these issues, but its impact on patients' monetary and time costs, especially in deprived areas, is under-researched.

Development of a territory-wide household-based composite index for measuring relative distribution of households by economic status in individual small areas throughout Hong Kong.

BMC Public Health

Social Statistics Division, Census and Statistics Department of the Government of the Hong Kong Special Administrative Region, Wanchai Tower, 12 Harbour Road, Wan Chai, Hong Kong Special Administrative Region, China.

Background: Many countries have developed their country/nation-wide multidimensional area-based index on deprivation or socioeconomic status for resource allocation, service planning and research. However, whether each geographical unit proxied by a single index is sufficiently small to contain a relatively homogeneous population remains questionable. Globally, this is the first study that presents the distribution of domestic households by the territory-wide economic status index decile groups within each of the 2,252 small subunit groups (SSUGs) throughout Hong Kong, with a median study population of 1,300 and a median area of 42,400 m.
