Physiological Changes in Japanese Students During a One‐Year Study Abroad Program in the United States

Abstract

We investigated changes in health and nutritional intake in a group of Japanese international students engaged in a one‐year study abroad program at a small college in the Pacific Northwest. 47 students (n= 15 M, age=19.85 and n= 32 F, age= 20.02) completed a survey that recorded changes in eating patterns, general health, and physical activity. Additionally, height, weight, BMI, body composition through bioelectrical impedance analysis (BIA), blood pressure, and blood lipid levels (total cholesterol, HDL, LDL, triglycerides, and TC/HDL ratio) were recorded at 3 time points: upon the students’ arrival, at 10 weeks and 20 weeks. Students self‐reported limited food consumption due to concerns about their health and meal point budgeting. Average weight increased (1.67±2.71 kg, p<0.01) after 7 months; most students recognized that their food intake was greater than in Japan. HDL cholesterol decreased during the same time frame (59.938±16.2 vs 48.625±16.6 mg/dL, p<0.001). 97% of students did not meet the ACSM/AHA weekly physical activity guidelines; lack of time, energy, and motivation were cited as reasons for not exercising. The results of this study indicate that it is important for host institutions to develop supportive, culturally responsive environments to enhance international students’ success while abroad and encourage healthy lifestyle behaviors through outreach interventions.Supported by a Willamette University Carson Grant to CRC.
