Family Rejection And Unprotected Sex Inlatino Gay Men, Juan Alejandro De Llano Montano Jan 2020

Family Rejection And Unprotected Sex Inlatino Gay Men, Juan Alejandro De Llano Montano

Walden Dissertations and Doctoral Studies

The present work explored the role of family rejection on the sexual behavior of Latino gay men under the guidance of the minority stress model. Family rejection was analyzed as a distal stressor, self-esteem as a proximal stressor, and unprotected sex as the outcome. The hypotheses were tested using regression, mediation, and multiple regression of secondary data from the Latino men who have sex with men (MSM) community involvement project. The results suggested that family rejection is a weak predictor of low self-esteem and engaging in receptive unprotected sex with more partners. Low self-esteem did not mediate the relationship between …

Neighborhood Factors, Depression, And Body Mass Index Among Patients With Lupus In Georgia, Aisha L. Hill Jan 2020

Neighborhood Factors, Depression, And Body Mass Index Among Patients With Lupus In Georgia, Aisha L. Hill

Walden Dissertations and Doctoral Studies

Elevated BMI (overweight and obesity) is a common health-related issue and affects more than half of the lupus population. Weight issues lead to additional health-related issues, such as heart disease and disabilities in the lupus population. To address the shortage of research focusing on this specific issue in the lupus population, one approach is a novel outlook on how neighborhood factors have the capability of determining or altering behaviors, such as physical activity, healthy eating, and healthy social relationships. Another variable to consider is depression and its capability of altering interactions, relationships, self-esteem, or even the inflammatory state of the …
