Melanoma Incidence Rates Among Non-Hispanic American Indian/Alaska Native Individuals, 1999-2019.

Importance: Non-Hispanic American Indian/Alaska Native people have the second highest incidence rate of invasive cutaneous melanoma in the US after non-Hispanic White people. Objective: To examine invasive cutaneous melanoma incidence rates and trends over time among non-Hispanic American Indian/Alaska Native people. Design, Setting, and Participants: This descriptive, observational cross-sectional study used population-based cancer registry data (US Cancer Statistics AI/AN Incidence Analytic Database) linked to the Indian Health Service administrative database to examine incidence rates by age, sex, region, histology, tumor site, stage, and other demographic and clinical characteristics. The study examined trends from 1999 to 2019 time period by age, sex, stage at diagnosis, and region. Non-Hispanic American Indian/Alaska Native people 15 years and older who received a diagnosis of invasive cutaneous melanoma from 1999 to 2019 who were members of federally recognized tribes and resided in Indian Health Service purchased/referred care delivery areas were included in this study to reduce racial misclassification and provide more accurate rates. The data were analyzed in 2022. Exposures: Demographic and clinical characteristics, such as age, sex, geographic region, histology, stage, and tumor site. Main Outcomes and Measures: Invasive cutaneous melanoma incidence rates by age group, sex, region, resident county characteristics (poverty level, rurality, education level, and socioeconomic status), stage at diagnosis, tumor site, and histology. Trends over time by age, sex, region, and stage. Results: From 1999 to 2019, 2151 non-Hispanic American Indian/Alaska Native people (1021 female individuals [47.5%]) received a diagnosis of incident cutaneous melanoma (rate, 10.7 per 100 000; 95% CI, 10.3-11.2). Rates were higher among male than female individuals (13.0 [95% CI, 12.2-13.8] vs 9.2 [95% CI, 8.6-9.8]) and for people 55 years and older (24.2; 95% CI, 22.8-25.7) compared with those aged 15 to 39 years (3.5; 95% CI, 3.2-3.9). Rates were highest for male individuals 55 years and older (34.5; 95% CI, 31.8-37.3) and people living in the Southern Plains (male individuals: 23.8; 95% CI, 21.5-26.2; female individuals: 15.5; 95% CI, 14.0-17.2) and Pacific Coast region (male individuals: 16.5; 95% CI, 14.5-18.7; female individuals: 12.3; 95% CI, 10.9-13.9). Rates increased among female individuals from 1999 to 2019 (average annual percent change [AAPC], 2.5; P < .001); among regional/distant stage tumors (AAPC, 2.5; P = .01) and people 55 years and older (AAPC, 2.8; P = .001). Conclusions and Relevance: The results of this study suggest that additional studies could potentially identify risk factors among non-Hispanic American Indian/Alaska Native people.

The Collaborative Research Center for American Indian Health's Partnership River of Life: Special Issue Introduction.

In 2012, the National Institutes of Health funded the Collaborative Research Center for American Indian Health (CRCAIH) to work toward two broad goals: 1) to build tribal research infrastructure, and 2) to increase research on social determinants of health in American Indian communities. As the introduction to this special issue of American Indian and Alaska Native Mental Health Research, we highlight results from the Partnership River of Life evaluation tool in order to provide broader context for the other manuscripts presented here. Insights were gained during the Partnership River of Life group discussion and evaluation process of combining the groups' rivers to create one representation of the CRCAIH partnership. Detailed results underscore insights for similar transdisciplinary groups.

Not a One-Size-Fits-All Approach: Building Tribal Infrastructure for Research Through CRCAIH.

The Collaborative Research Center for American Indian Health (CRCAIH) was created to foster tribal partnerships in the Minnesota, North Dakota, and South Dakota regions to increase capacity for tribal research. Since 2013, through community engagement and technical assistance from CRCAIH's cores and divisions, seven tribal partners have expanded research infrastructure and recognize the benefits of an established tribal research office. This manuscript showcases the unique approaches individual CRCAIH tribal partners have taken to build tribal research infrastructure. The unique experiences of the CRCAIH tribal partnership holds valuable lessons for other tribes interested in increasing research capacity through research review, regulation, and data management.

Using Social Network Analysis to Visualize Networks in American Indian Health Research.

The Collaborative Research Center for American Indian Health (CRCAIH) is a transdisciplinary, collaborative center focused on building American Indian tribal research infrastructure. Funded by the National Institute of Minority Health and Health Disparities in 2012, it was created as a platform to join tribal communities and researchers in South Dakota, North Dakota, and Minnesota to develop research infrastructure and stimulate research in American Indian health. The CRCAIH infrastructure has created a large network of transdisciplinary research partnerships. To understand the initial development of the CRCAIH network and understand the broader impact it has had on American Indian and Alaska Native health research, CRCAIH undertook a network analysis based on publications by collaborators working with and within CRCAIH. The network analysis showed how far the CRCAIH network went in a short period of time to create a platform for networking to build collaborations and further stimulate research with American Indian communities.
