The purpose of this study was to investigate the behavioral impact of knowledge regarding the relationship between breast cancer, vitamin D supplementation, and sunlight exposure considering levels of self-efficacy and response-efficacy. The study was based on protection motivation theory, which attributes behavior change to cognitive processes related to perceived threats and has demonstrated efficacy in promoting breast cancer risk-reducing behaviors. The study employed a quasi-experimental research design based on a survey using SurveyMonkey. Participants were New York City-residing women ranging in age from 25 to 74 who were recruited via an invitation from SurveyMonkey. Correlation analysis and linear regression analysis were performed on the data extracted from the survey in order to better understand the relationship of the variables in this study, and to test if any of the independent variables were significant predictors of vitamin D intake through supplementation and sunlight exposure. The results of this analysis showed that knowledge regarding the reduction in risk of breast cancer from sunlight exposure and through vitamin D supplementation was not related to changes in behavior involving increases in sunlight exposure and vitamin D intake through supplementation. Further, the results showed that those participants with higher levels of self-efficacy and response-efficacy regarding sunlight exposure and vitamin D supplementation had an increased amounts of vitamin D intake through supplementation on a daily basis. The results of this study can be used to help medical professionals understand the complexity involved in how their clients may or may not take action to reduce the potential for reducing the risk of breast cancer.

The use of human immunodeficiency virus (HIV) counselling and testing (HCT) is a necessary component of implementing HIV prevention and control programs in Nigeria. Knowledge, acceptance, and use of HCT remain low in Nigeria, especially among young people ages 15 to 24 years. The purpose of this study was to ascertain how sociodemographic factors (i.e., gender, place of residence, level of education, geopolitical zone, and socioeconomic status [SES]); cognitive factors (i.e., HCT awareness, knowledge of HIV prevention, and knowledge of HIV transmission); and knowledge of sexual risk behaviors affected HCT uptake among young people in Nigeria using data from the 2013 National HIV/AIDS and Reproductive Health Survey Plus. The study was guided by the social cognitive theory. The sample was composed of 10,091 young people ages 15 to 24 years from all geopolitical zones, SES, and educational backgrounds in Nigeria. Multiple regressions and multivariate comparisons revealed a significant relationship between HCT awareness and HCT uptake (p < .001) and between knowledge of HIV prevention and HCT uptake (p < .001). Sociodemographic variables of gender, place of residence, level of education, geopolitical zone, and SES were also significantly associated with HCT uptake. The sexual risk behavior variables tested were not significantly associated with HCT uptake among young people in Nigeria. The implications for positive social change include providing public health professionals with data to plan and implement HCT awareness and knowledge programs for young people in Nigeria that could increase HCT uptake and reduce the incidence of HIV/AIDS.
