Relationship between sleep and obesity among U.S. and South Korean college students
Background
Little is known about the relationship between sleep and obesity in young adults, particularly college students. This study examined the relationship between sleep (i.e., sleep duration and quality) and obesity in a large and diverse binational sample of college students. Methods
Analyses were based on a 40-item paper survey from 2016/2017 to 2017/2018 academic years, with a 72% response rate. The samples were 1578 college students aged 18–25 years from five universities (two in the U.S. and three in South Korea). Weight and height were measured objectively; other measures (e.g., health behaviors) were self-reported. Multinomial logistic regression was used to assess the association between sleep duration and independent variables (race/nationality, gender, and BMI). Poisson regression was used to examine the relationship between sleep quality and independent variables. Results
Overall, blacks had a higher adjusted odds ratio (AOR) of short sleep (\u3c 7 h/night) than whites (AOR = 1.74, P \u3c .01); overweight participants had a higher AOR of short sleep than normal weight participants (AOR = 1.52, P \u3c .01); and obese participants had a higher AORs of both short and long sleep (\u3e 9 h/night) (AOR = 1.67, P \u3c .01; AOR = 1.79, P \u3c .05, respectively). Among men, being black, overweight, and obesity were associated with short sleep (P \u3c .05), whereas only obesity was related to short sleep among women (P \u3c .05). In analyses stratified by race and nationality, overweight and obesity were related to short sleep among blacks only (P \u3c .05). Overall, sleep quality (getting enough sleep to feel rested in the morning in the past 7 days) was worse in blacks and South Koreans than whites (P \u3c .05), worse in women than men (P \u3c .05), and worse in participants with obesity than normal weight participants (P \u3c .05). Conclusions
Obesity was associated with both short (\u3c 7 h/night) and long sleep duration (\u3e 9 h/night) and poor sleep quality among all participants. In comparison with whites, blacks were more like to have short sleep, and blacks and South Koreans had worse sleep quality. Further investigations using a larger sample of college students in multiple countries may be helpful to identify target populations who are at a greater risk of obesity and sleep problems

Overall, blacks had a higher adjusted odds ratio (AOR) of short sleep ( 9 h/night) (AOR = 1.67, P < .01; AOR = 1.79, P < .05, respectively). Among men, being black, overweight, and obesity were associated with short sleep (P < .05), whereas only obesity was related to short sleep among women (P < .05). In analyses stratified by race and nationality, overweight and obesity were related to short sleep among blacks only (P < .05).

Sex and racial/ethnic differences in suicidal consideration and suicide attempts among US college students, 2011-2015.
Objectives: In this study, we examined sex and racial/ethnic differences in the prevalence and predictors of suicide consideration and attempts among US college students. Methods: We used multivariable logistic regression to investigate suicide consideration and attempts by sex and race/ethnicity among students (N = 319,342) who completed the American College Health Association- National College Health Assessment from fall 2011 to spring 2015. Results: Overall, the prevalence of suicide consideration and attempts was higher in spring 2015 than fall 2011 (p \u3c .05). Men had higher odds of suicide consideration and attempts than women (p \u3c .001). Blacks, Hispanics, and Asians had higher odds of suicide consideration and attempts compared with Whites (p \u3c .001). Weight-related problems (unhealthy weight, body weight overestimation, and lack of physical activity), sleep problems (insufficient sleep and sleep difficulties), and lower levels of academic performance were associated with both suicide consideration and attempts (p \u3c .05). Conclusions: Our findings indicate a need for sex- and race/ethnicity-specific suicide prevention strategies for college students, specifically men and racial/ethnic minority groups. Furthermore, appropriate weight and sleep management could be considered to help prevent suicide among US college students. (PsycInfo Database Record (c) 2021 APA, all rights reserved
Sex and racial/ethnic differences in the prevalence of overweight and obesity among U.S. college students, 2011–2015
Objective
To investigate sex and racial/ethnic differences in overweight and obesity in college students. Participants: A nationally representative sample of 319,342 U.S. college students (mean age = 20.4 years; 67.7% female) from Fall 2011 to Spring 2015. Methods: A secondary data analysis of multi-year cross-sectional data was performed. Multiple logistic regression was used to examine factors (e.g. cumulative grade average, year in school, and living place) associated with overweight and obesity determined from BMI calculated by self-reported height and weight. Results: The prevalence of overweight and obesity was significantly higher for both sexes in Spring 2015 than in Fall 2011. Significant differences were found in overweight and obesity by sex and race/ethnicity. Higher adjusted odds ratios for overweight and obesity were observed for men, blacks, and Hispanics (compared to whites). Asians had the lowest adjusted odds of overweight and obesity. Conclusions: Intervention strategies for the prevention and management of overweight and obesity in U.S. college students should consider sex and racial/ethnic inequalities

The samples were 1578 college students aged 18–25 years from five universities (two in the U.S. and three in South Korea). Weight and height were measured objectively; other measures (e.g., health behaviors) were self-reported. Multinomial logistic regression was used to assess the association between sleep duration and independent variables (race/nationality, gender, and BMI). Poisson regression was used to examine the relationship between sleep quality and independent variables.
Results
Overall, blacks had a higher adjusted odds ratio (AOR) of short sleep ( 9 h/night) (AOR = 1.67, P < .01; AOR = 1.79, P < .05, respectively). Among men, being black, overweight, and obesity were associated with short sleep (P < .05), whereas only obesity was related to short sleep among women (P < .05). In analyses stratified by race and nationality, overweight and obesity were related to short sleep among blacks only (P < .05).

Obesity was associated with both short ( 9 h/night) and poor sleep quality among all participants. In comparison with whites, blacks were more like to have short sleep, and blacks and South Koreans had worse sleep quality.

Sleep Duration and Weight Gain among Students at a Historically Black University
Objective: We investigated sex differences in sleep and examined the association between objectively-measured sleep characteristics and weight gain among 54 black students at a historically black university in spring 2018. Methods: Participants wore a wearable tracker (Fitbit Alta) for an average of 68 days of sleep over the spring semester and 5.5 days of sleep over the spring break. They also completed a questionnaire. Results: Average sleep duration was 6 hours 35 minutes. More women had short sleep (\u3c 7 hours / night) than men (92.1% vs 43.8%; p \u3c .001). Women had shorter sleep (6 hours 24 minutes vs 7 hours 1 minute; p = .003), shorter naps (2 hours 4 minutes vs 2 hours 30 minutes; p = .043), and lower sleep efficiency (93.0% vs 94.1%; p = .048) than men. More women than men experienced weight gain (79.0% vs 68.8%, p \u3c .05). We found an inverse relationship between sleep duration and weight gain in both sexes (r = -0.42, p \u3c .05). Conclusions: Appropriate sleep and weight management should be considered to address sex disparities in sleep and weight gain among black students at historically black universities
