Health-Related Behavioral Risk Factors and Obesity Among American Indians and Alaska Natives of the United States: Assessing Variations by Indian Health Service Region

Chronic respiratory disease in Indigenous peoples: a framework to address inequity and strengthen respiratory health and health care globally

Indigenous peoples around the world bear a disproportionate burden of chronic respiratory diseases, which are associated with increased risks of morbidity and mortality. Despite the imperative to address global inequity, research focused on strengthening respiratory health in Indigenous peoples is lacking, particularly in low-income and middle-income countries. Drivers of the increased rates and severity of chronic respiratory diseases in Indigenous peoples include a high prevalence of risk factors (eg, prematurity, low birthweight, poor nutrition, air pollution, high burden of infections, and poverty) and poor access to appropriate diagnosis and care, which might be linked to colonisation and historical and current systemic racism. Efforts to tackle this disproportionate burden of chronic respiratory diseases must include both global approaches to address contributing factors, including decolonisation of health care and research, and local approaches, co-designed with Indigenous people, to ensure the provision of culturally strengthened care with more equitable prioritisation of resources. Here, we review evidence on the burden of chronic respiratory diseases in Indigenous peoples globally, summarise factors that underlie health disparities between Indigenous and non-Indigenous people, propose a framework of approaches to improve the respiratory health of Indigenous peoples, and outline future directions for clinical care and research.

Urgent versus elective surgical disparities among American Indian and Alaska Native patients

BACKGROUND

American Indian and Alaska Native (AIAN) health issues are understudied despite documentation of lower-than-average life expectancy. Urgent surgery is associated with higher rates of postsurgical complications and postoperative death. We assess whether American Indian and Alaska Native (AIAN) patients in Washington State are at greater risk of requiring urgent rather than elective surgery compared with non-Hispanic Whites (NHW).

METHODS

We accessed data for the period 2009-2014 from the Washington State Comprehensive Hospital Abstract Reporting System (CHARS) database, which captures all statewide hospital admissions, to examine three common surgeries that are performed both urgently and electively: hip replacements, aortic valve replacements, and spinal fusions. We extracted patient race, age, insurance status, comorbidity, admission type, and procedures performed. We then constructed multivariable logistic regression models to identify factors associated with use of urgent surgical care.

RESULTS

AIAN patients had lower mean age at surgery for all three surgeries compared with NHW patients. AIAN patients were at higher risk for urgent surgery for hip replacements (OR = 1.49, 95% CI 1.19-1.88), spinal fusions (OR = 1.39, 95% CI 1.04-1.87), and aortic valve replacements (OR = 2.06, 95% CI 1.12-3.80).

CONCLUSION

AIAN patients were more likely to undergo urgent hip replacement, spinal fusion, and aortic valve replacement than NHW patients. AIAN patients underwent urgent surgery at younger ages. Medicaid insurance conferred higher risks for urgent surgery across all surgeries studied. Further research is warranted to more clearly identify the factors contributing to disparities among AIAN patients undergoing urgent surgery.

Associations of pedometer-measured ambulatory activity with incidence of atherosclerotic cardiovascular diseases: Strong heart family study

OBJECTIVE

Coronary heart disease has several risk factors that require a multifactorial community intervention approach in prevention efforts. Prevalence of coronary heart disease and its risk factors have been disproportionately high among American Indians. The objective of this study is to evaluate the impact of ambulatory activity levels on the development of coronary heart disease in this population.

METHODS

Using pedometer data and other lifestyle and clinical factors from 2492 participants in the Strong Heart Family Study, we examined the associations of average daily step counts with incident coronary heart disease during an 18 to 20 year follow-up.

RESULTS

After adjusting for potential confounders, participants with daily step counts in the 4th quartile (>7282 steps per day) had significantly lower odds of developing coronary heart disease compared to those in the 1st quartile (<3010 steps per day) (p = 0.035).

CONCLUSIONS

Higher daily step count (over 7282 steps per day) is significantly associated with lower incidence of coronary heart disease among American Indian participants of the Strong Heart Family Study in a 20-year follow-up period.

Maternal Malnutrition During Pregnancy Among Women with Metabolic and Bariatric Surgery

INTRODUCTION

As the utilization of metabolic and bariatric surgery (MBS) continues to rise, it is important to address the nutritional needs of women who had MBS who become pregnant. Not meeting those nutritional needs could lead to complications associated with malnutrition. To better understand the relationship between MBS, pregnancy, and malnutrition, this study sought to determine whether differences exist in the presence of malnutrition during pregnancy in women with a history of MBS compared to women without a history of MBS.

METHODS

This cross-sectional study used the National Inpatient Sample (NIS) from 2012 to 2017, which samples 20% of hospital discharges in the USA. Multivariate logistic regression models were fitted, and odds rations and 95% confidence intervals were calculated with obesity and MBS as the independent variables and malnutrition during pregnancy as the dependent variable. Covariates included in the multivariate model were age, primary payer, hypertension, hyperlipidemia, and depression.

RESULTS

Compared to women who did not have MBS, women who had MBS had higher odds of malnutrition during pregnancy (aOR = 8.33, 95% CI 7.30-9.50), this result was moderated by racial category (aORBlack = 6.35, 95% CI 4.97-8.13; aORwhite = 8.25, 95% CI 7.00-9.73; aORLatina = 10.93, 95% CI 8.38-14.25). Women with obesity also had higher odds of malnutrition during pregnancy.

CONCLUSIONS

The increased odds of malnutrition among women with MBS suggests that it is important to consider tailoring nutrition recommendations to address the different nutritional needs of pregnant women who had MBS and may be at risk for malnutrition.

The commercial determinants of Indigenous health and well-being: a systematic scoping review

INTRODUCTION

Health inequity within Indigenous populations is widespread and underpinned by colonialism, dispossession and oppression. Social and cultural determinants of Indigenous health and well-being are well described. Despite emerging literature on the commercial determinants of health, the health and well-being impacts of commercial activities for Indigenous populations is not well understood. We aimed to identify, map and synthesise the available evidence on the commercial determinants of Indigenous health and well-being.

METHODS

Five academic databases (MEDLINE Complete, Global Health APAPsycInfo, Environment Complete and Business Source Complete) and grey literature (Australian Indigenous HealthInfoNet, Google Scholar, Google) were systematically searched for articles describing commercial industry activities that may influence health and well-being for Indigenous peoples in high-income countries. Data were extracted by Indigenous and non-Indigenous researchers and narratively synthesised.

RESULTS

56 articles from the USA, Canada, Australia, New Zealand, Norway and Sweden were included, 11 of which were editorials/commentaries. The activities of the extractive (mining), tobacco, food and beverage, pharmaceutical, alcohol and gambling industries were reported to impact Indigenous populations. Forty-six articles reported health-harming commercial practices, including exploitation of Indigenous land, marketing, lobbying and corporate social responsibility activities. Eight articles reported positive commercial industry activities that may reinforce cultural expression, cultural continuity and Indigenous self-determination. Few articles reported Indigenous involvement across the study design and implementation.

CONCLUSION

Commercial industry activities contribute to health and well-being outcomes of Indigenous populations. Actions to reduce the harmful impacts of commercial activities on Indigenous health and well-being and future empirical research on the commercial determinants of Indigenous health, should be Indigenous led or designed in collaboration with Indigenous peoples.
