This cross-sectional study examined the relationships between length of residence in the United States (U.S.) and dietary and physical activity acculturation, and the relationships between dietary and physical activity acculturation and weight status in 55 Chinese college students. Length of residence in the U.S. was positively associated with larger portion size, greater amount of physical activity, and change in BMI in male participants. Adoption of a Western diet was associated with weight gain. Portion size change was positively associated with BMI change. Lunch size change was positively correlated with BMI change in males while negatively correlated with BMI change in females. And dinner size change was positively correlated with BMI change in males. This study suggests that dietary acculturation is positively associated with weight gain in Chinese college students. Future interventions focusing on multi-dimensional aspects of dietary behavior change--especially portion size and meal size changes--while emphasizing the importance of changes in physical activity are needed. Such interventions may help maintain healthy weight status and prevent individuals in this population from becoming overweight or obese.

The initial development of a social services program in a college health setting is presented, with discussion regarding causes, methods, and outcomes. Both empirical and anecdotal data which were influential in the initial formation of the program are reviewed, in the context of an examination of the research literature relating to this area. The actual development and implementation of the program is followed through its first year of existence. Outcomes are presented in the form of qualitative data analysis and case studies. Discussion of the results and recommendations for both future research and improvements to the program are presented.

eHealth is commonly defined as health services and information provided through the Internet and related technologies. Health educators have taken advantage of Internet and social media venues to disseminate health information essential to health risk management, disease prevention, and disease management and did not have a validated theoretical model to explain their experiences. The goal of this study was to create and test an integrated model of eHealth communication specific to 18-30 year old college students based on five research questions that identified and confirmed the factors most highly correlated with the presentation of health information on Internet or social media venues that improve eHealth literacy and provoke eHealth behavioral intention among college students. A sample of over 1400 18-30 year old college students was surveyed about their general and health information related use of the Internet and social media. As a result of exploratory factor analysis and subsequent structural equation modeling, the proposed theoretical model was revised and tested for statistical power. Two revised integrative models of eHealth communication, one for Internet and one for social media, were developed and validated. The model for social media shows statistically significant paths throughout the model; however, the model for the Internet reveals that the path between two constructs and Online Health Behavior are not statistically significant and is worthy of further examination. This study has important practical implications for eHealth educators, organizations dedicated to informing the public about specific diseases or health promotion techniques, health practitioners seeking improved strategies for effective eHealth message design, and to health information professionals.

Thesis (MTech (Nursing))--Cape Peninsula University of Technology, 2018 / Health risks are continuing to be a challenge worldwide. Globally, young people aged 15-24 are amongst the most vulnerable groups. It was revealed that between 2007 and 2010, the rate of HIV infection increased in this age group. In sub-Saharan Africa, three out of four new HIV infections are amongst girls aged 15 to 19 years of age. Young women aged 15 to 24 are twice more likely to live with HIV than men in 2019. South Africa is the country with the largest human immunodeficiency virus (HIV) infected population in the world, with an estimated 7 million people living with HIV and 380 000 new HIV infections in 2015. University students are a very important group of young people because they are being prepared for the world of work and to assume leadership roles. However, they are the group most exposed to a range of health risks, particularly regarding sexuality and HIV/AIDS. The aim of this study was to explore potential health risk factors amongst students at a Higher Education Institution (HEI) in the Western Cape with regard to sexuality and HIV/AIDS. The objectives of the study were to explore the factors that may increase health risk behaviours amongst students at an HEI and to discover and describe the knowledge university students have regarding potential health risks related to sexuality and HIV/AIDS. A qualitative research design was employed. Focus group interviews were done to collect data and a thematic content analysis was employed to analyse the data. Results revealed that the university students engaged in high-risk sexual behaviours, such as transactional sex, casual sex, multiple partner sexual relationships and unprotected sex. Such behaviours lead to a high-risk of contracting STIs and HIV/AIDS. Among the factors that were found to be contributing to these risky behaviours, was the new-found freedom of being away from the supervision of parents. Peer pressure at HEIs, as well as abuse of alcohol and drugs, also contribute to risky behaviours. Recommendations were that there should be organised and measured approaches to expose both lecturers and the students to HIV/AIDS education through an integrated curriculum design. There should be teamwork amongst lecturers, support staff and students to create powerful discussions and an exchange of ideas to clarify issues regarding HIV/AIDS, sexuality and other related topics to reduce high-risk behaviours and promote solid constructive attitudes amongst the university community.

The present study set out to investigate the biopsychosocial model of illness using variables previously identified as directly impacting illness or as mediating the relationship between other variables and illness. Oral contraceptive use, stress, and negative affect were investigated as predictors of immunological competence, measured by the level of Immunoglobulin G antibodies to Epstein-Barr Virus Viral Capsid Antigen (EBV-VCA IgG).

Hematocrit, serum-iron and iron-binding capacity were used to test the iron status of a sample of fifty-six volunteer students. Subjects completed a questionnaire to examine whether a correlation exists between iron status and iron knowledge. The sample, including 20 males and 36 females, consisted of ten nutrition majors , eight biology majors, thirty-eight other majors, and eight vegetarians. The four measures revealed that a high prevalence of iron deficiency did not exist in this student population. Other findings: sex and iron status are not related; no correlation exists between iron knowledge and iron status; and vegetarians have an iron status comparable to that of non-vegetarians.

The study explored the factors influencing the use of voluntary counselling and testing by university students. This was done by undertaking an exploratory and descriptive qualitative study. Focus group discussions and field notes were used to collect data from the participants. Outcomes from the study revealed various factors to the uptake of Voluntary Counselling and Testing (VCT) services by university students namely: the desire to know one‟s HIV status, illness, pregnancy, blood donation, to get a reward, the influence of significant others, the influence of media, awareness campaigns, compulsion, to get a job, curiosity, to be a positive role model and the positive attitude and professional conduct of the health care provider. The study also revealed various challenges to the uptake of VCT services by university students namely: the fear of being diagnosed HIV positive, HIV/AIDS-related stigma and discrimination, the low perception of risk to HIV infection, the lack of student friendly VCT services, the shortage of human and infrastructural resources, the inaccessibility of VCT services, the long waiting period for test results, negative perceptions about VCT, the problems with pre-test counselling and ignorance. Going by the participants‟ suggestions VCT services uptake by university students could be improved by increased resource allocation (incentives, human and infrastructural resources), increased awareness campaigns, and improved counselling and making VCT services more accessible / Information Science / MA (Public Health)

Thesis (MPhil)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Health information-seeking is a complex and dynamic construct. This study attempted to quantify and explain the use of interpersonal communication, media and related technologies as health information sources among first year university students on the campus of Stellenbosch University (SU), using a cross-sectional survey design. The questionnaire and web-based survey intended to measure and document important research constructs at a single point in time. Data from this survey provide exploratory information on patterns of health information-seeking practices and preferences encountered among the research target group. Measures of the reasons for health information-seeking on specific topics; health information sources/channels and frequency of source/channel use; information source credibility and quality as well as the outcomes of the health information-seeking process were used as secondary research aims in this study. Health communication and health management needs of the research population were also important research variables to establish. Results from this research indicate that the health status of the study cohort was good. The mean of the BMI kg/m² for the current study cohort lies at the higher end of the BMI kg/m² continuum for this age group, which indicates that the lifestyle of the study cohort is at risk. The use of health information sources among the research cohort was diverse. This research confirms that interpersonal communication is an important information medium through which young adults receive health information. The concept of an ecological context to health communication and its effects are therefore supported by these results. Use of media sources and related technology was common and diverse among the study cohort, mirroring patterns of media use for other young adult groups. Results further support the theory of effect-studies in communication (the media), where the provision of certain types of information through the media, indicate to have an impact on people’s thinking and behaviour. A behaviour change as result of the health information-seeking process was reported among the research cohort. Health communication literature refers to small numbers of studies conducted on health information-seeking among young adults (student populations). The current research has attempted to add to the body of knowledge on health information-seeking and its outcomes among a student population group in a South African university setting. / AFRIKAANSE OPSOMMING: Die soektog na gesondheidsinligting is 'n dinamiese en komplekse proses. Hierdie navorsing het gepoog om die gebruik van interpersoonlike kommunikasie, media en verwante tegnologieë as inligtingsbronne oor gesondheid onder eerstejaar-studente op die kampus van die Universiteit van Stellenbosch (US) te kwantifiseer en te verklaar. 'n Dwarsdeursnitopname is as studieontwerp gebruik. Die web-gebaseerde vraelys het gepoog om belangrike navorsingskonstrukte tydens 'n enkele tydgleuf te probeer meet. Data van hierdie opname verskaf verkennende inligting oor die patrone van die soeke na gesondheidsinligting en gesondheidsinligtingvoorkeure van studente. Redes vir die soek na gesondheidsinligting; mediums/metodes waardeur inligting verkry word; frekwensie van soektogte; geloofwaardigheid van mediums en die kwaliteit daarvan; onderwerpe waarna gesoek word en die uitkomste van hierdie gesondheidsinligtingsoektog, is as sekondêre navorsingsuitkomste van belang geag. Gesondheidskommunikasiebehoeftes onder die navorsingsteikengroep was belangrik om vas te stel. Resultate van die navorsing dui aan dat die gesondheidstatus van die navorsingsgroep goed was. Die gemiddelde BMI kg/m² vir die groep was egter aan die bokant van die BMI kg/m² kontinuum vir die ouderdomsgroep en dui op moontlike leefstylrisiko’s vir die groep. Die gebruik van gesondheidsinligtingsbronne was baie divers. Hierdie navorsing ondersteun die feit dat interpersoonlike kommunikasie, as gesondheidsinligtingsbron, nog 'n belangrike rol speel onder jong volwassenes. Die konsep van 'n ekologiese konteks vir gesondheidskommunikasie en die uitwerking daarvan, word ondersteun deur die huidige navorsingsresultate. Die gebruik van media en verwante tegnologieë, as inligtingsbronne vir gesondheid, is as baie divers gerapporteer. Dit bevestig patrone van mediagebruik wat onder ander jong volwassenes gevind is. Resultate van hierdie navorsing ondersteun ook die teorie van effek-studies in kommunikasie (die media), waar die verskaffing van inligting deur die media 'n impak op mense se denke en gedrag aandui. 'n Gedragsverandering is wel deur die navorsingsgroep aangedui as resultaat van die soeke na gesondheidsinligting. Gesondheidskommunikasieliteratuur verwys na enkele studies wat oor gesondheidsinligtingsoektogte onder jong volwassenes (studente-populasies) gedoen is. Die huidige navorsing het gepoog om 'n bydrae te maak tot hierdie kennis en die uitkomste daarvan onder studente op 'n Suid-Afrikaanse universiteitskampus.
