Study summary

Background:

As of 2021, almost 45 million people in the United States were foreign-born immigrants. South Asians, including people from Bhutan, are the fastest-growing immigrant subgroup in the US. Their income and education levels are higher than the US average. Yet they have worse physical and mental health outcomes than their White US-born counterparts. These risks include type 2 diabetes and obesity.

Objective:

This natural history study will explore how life experiences and environmental factors affect heart health and metabolism among Bhutanese people living in the US.

Eligibility:

Adults aged 18 years or older who identify as Bhutanese and live in the US.

Design:

Participants will be recruited and screened by the Bhutanese Community of Central Ohio (BCCO). They will have 1 visit to the BCCO s Arogya Clinic in Reynoldsburg. The visit will last 2 hours.

Participants will take a survey; they may use either English or Nepali. They will answer questions about their background; their experiences living in the US; and how their customs and habits might have changed. They will also be asked about their experiences with discrimination; their mental health and well-being; their community; quality of life; and overall physical health. The survey will take 60 minutes.

Participants will also speak with a researcher. They will be asked how they feel about providing biological samples; these may include saliva, blood, and urine. Their answers will be audio recorded.

Study Description:

In 2021 we completed a cross-sectional feasibility study to assess cardiometabolic health of the Bhutanese refugee community in central Ohio. This is a cross-sectional pilot to assess the feasibility of establishing a long-term cohort study among the Bhutanese community to provide representation of a hardly-reached demographic group, optimize collection of behavioral and biological data. Schedule of Activities, describes the study activities including a survey assessing the participants experiences and a brief qualitative assessment examining the feasibility of obtaining biological samples.

Objectives:

The objectives are as follow:

Primary Objective: (Aim 1) To summarize socioecological characteristics of acculturation and cardiometabolic health from >=18-year-old adults United States Bhutanese living in Central Ohio.

Secondary Objectives: (Aim 2) To identify barriers and facilitators to biospecimen donation among United States Bhutanese adults living in Central Ohio.

Endpoints:

Primary Objective: (Aim 1) Summary on self-reported constructs of acculturation and acculturative stress, discrimination and stigma, health behaviors, medical history and health behaviors, mental health, sleep health, neighborhood social cohesion and community support, trauma, and medical history of cardiometabolic conditions.

Secondary Objectives: (Aim 2) Description of barriers and facilitators to biospecimen donation from US Bhutanese participants identified by qualitative inquiry and analysis of beliefs on biospecimens and invasiveness.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
