Developing a Total Worker Health® Climate Survey

We are seeking organizations who are interested in participating in a research project developing a Total Worker Health climate survey to help organizations build strong cultures for safety, health and well-being. Participating organizations may benefit directly through (1) identifying disconnects between company policies and actual operational practices, (2) identifying program underperformance, (3) improving employee participation across safety, health and well-being, (4) improving ROI, (5) a safer and healthier workplace, and (6) lower turnover rate, higher job satisfaction and increased employee engagement.

Qualifying organizations will have 500 or more employees and can be from any sector. We are also particularly interested in companies from the utility, manufacturing, and transportation sectors. Participating organizations are requested to (1) provide a letter of intent to participate to be included in the grant application (researchers will provide templates for the participant’s convenience), and (2) allow all employees to complete a one-time, online 15-20 minute survey during working hours. The survey can be completed on any computer or mobile device (i.e., PC, tablet device, smart phone). 

Interested companies should contact Dr. Emily Huang and the Safety Climate Lab at SafetyClimate@ohsu.edu. We would like to hear from you if you are interested in getting involved with safety culture and climate work!

Health disparities in hypertension

We are looking for healthy people aged 30-60 for a study focused on hypertension and sleep. We are investigation how behaviors (such as exercise and changes in posture) and the body's internal clock (called the circadian rhythm) affect the control of the heart and blood pressure. Eligible participants may have normal blood pressure or have mild hypertension with no current medication use and no history of cancer, heart disease, or other chronic illness. Initial screening involves 2-4 hospital visits followed by establishing a 1-3 week home sleep and activity routine. If successfully completed, this will be followed by a 6 night in-lab stay. Compensation up to $2,400 will be provided.

If you are interested in participating, please access our pre-screening survey here.

Circadian mechanisms of cardiovascular risk in obesity

We are looking for healthy people aged 25-65 for a study focused on body weight and sleep. We are investigation how behaviors (such as exercise and changes in posture) and the body's internal clock (called the circadian rhythm) affect the control of the heart and blood pressure. Eligible participants may be lean or overweight with no current medication use and no history of cancer, heart disease, or other chronic illness.Initial screening involves 2-4 hospital visits followed by establishing a 1-3 week home sleep and activity routine. If successfully completed, this will be followed by a 5 day in-lab stay. Compensation up to $1,700 will be provided.

If you are interested in participating, please access our pre-screening survey.

Sleep duration and cardiovascular health

We are looking for healthy people aged 25-65 with average sleep per night either ≤ 6hrs, ≥ 9hrs, or between 7-8hrs. We are investigating how various sleep durations affect cardiovascular health. Eligible participants may be lean or overweight (BMI <40) with no current medication use and no history of cancer, heart disease, smoking, or other chronic illness. Initial screening involves online questionnaires followed by 1 week of at-home sleep and activity monitoring. If successfully completed, this will be followed by 1-2 in-lab visits (1-2 hours each). Compensation up to $170 will be provided.

Sedentary behavior, cardiovascular health and sleep

We are looking for moderately active, healthy people aged 20-80y that get most of their exercise from walking. We are investigating how sedentary behavior (reduced activity) affects cardiovascular health and sleep. Eligible participants may be lean or overweight (BMI <40) with no current medication use and no history of cancer, heart disease, or other chronic illness. Initial screening involves 1 hospital visit followed by 1 week of at-home sleep and activity monitoring. If successfully completed, this will be followed by 3 weekly in-lab visits (4.5 hours each), with at-home sleep and activity monitoring for the duration of the study (3 weeks). Compensation up to $375 will be provided.

Sleep and Circadian Mechanisms in Hypertension

We are seeking participants aged 25-64y with untreated high blood pressure (>130/80 mmHg). The purpose of this study is to learn more about how the body’s internal clock (or circadian rhythm) affects the cardiovascular system in people with untreated high blood pressure. It will not cost you or your insurance anything to participate. Research will cover all the costs to participate, and we will pay you up to $1,900 for volunteering. You will receive a physical, at-home and in-laboratory sleep monitoring, a sleep apnea report, and blood work and blood pressure reports to share with your medical provider. Participants must have no history of cardiovascular diseases, psychological conditions, sleep disorders, or other acute/ chronic diseases.

If you are interested in participating, please email clinphys@ohsu.edu and use ‘Hypertension Study’ in the subject line. Alternatively, please call Nicole at 503-494-5536.
