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, 15-20-minute online survey during working hours. The survey can be completed on any computer or mobile device (i.e., PC, tablet device, smartphone).

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!

We are looking for healthy people aged 30-60 for a study focused on hypertension and sleep. We are investigating 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 two to four hospital visits followed by establishing a one- to three-week home sleep and activity routine. If completed, this will be followed by a six-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.

We are looking for healthy people aged 25-65 for a study focused on body weight and sleep. We are investigating 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 illnesses. Initial screening involves two to four hospital visits followed by establishing a one- to three-week home sleep and activity routine. If completed, this will be followed by a five-day in-lab stay. Compensation up to $1,700 will be provided. If you are interested in participating, please access our pre-screening survey.

We are looking for healthy people aged 25-65 with an average sleep per night of either ≤ six hours, ≥ nine hours, or between seven and eight hours. 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 illnesses. Initial screening involves online questionnaires followed by one week of at-home sleep and activity monitoring. If successfully completed, this will be followed by one or two in-lab visits (one to two hours each). Compensation up to $170 will be provided. If you are interested in participating, please access our pre-screening survey here.

We are looking for healthy people aged 20-39 years for a study on exercise and cardiovascular health. We are investigating how the body’s internal body clock (or circadian rhythm) affects the cardiovascular system in response to exercise. Eligible participants may be lean or overweight (BMI <30) with no current medication use and no history of cancer, heart disease, other chronic illness, or smoking. Initial screening involves one evening of melatonin monitoring in the lab (up to nine hours) and one 30-hour stay in the laboratory with meals, sleep, and exercise at regular intervals across the period. Compensation up to $400 will be provided. If you are interested in participating, please email clinphys@ohsu.edu and use ‘CRYPTEX Study’ in the subject line. Alternatively, please contact Megan at 503-494-4311.

We are seeking participants aged 25-64 years 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.
