Emerging adulthood is a developmental period associated with increased engagement in health risk behaviors, particularly in college students with attention-deficit/hyperactivity disorder (ADHD), a disorder characterized by low distress tolerance and significant difficulty managing emotions. However, research has not examined how these factors impact propensity to engage in health risk behaviors in college students with ADHD. Thus, this study examined the independent and joint effects of ADHD status, emotion regulation, and distress tolerance on the propensity of college students to engage in health risk behaviors (alcohol use, impulsive eating, and drug behaviors). Participants included 143 undergraduate students (81.8% female; 44.1% with ADHD) who completed an online questionnaire via REDCap. Individuals with ADHD reported significantly higher use of maladaptive emotion regulation strategies and lower levels of distress tolerance than the comparison sample. Moderation models using the PROCESS macro for SPSS examined whether the associations between emotion regulation abilities and distress tolerance with health risk behavior engagement were moderated by ADHD diagnostic history. The relation between distress tolerance and engagement in drug use behaviors was moderated by ADHD status, such that for individuals with ADHD, poorer distress tolerance was associated with more drug use. ADHD status also moderated the association between maladaptive emotion regulation strategies and cognitive restraint in eating. For individuals without ADHD, more maladaptive emotion regulation was marginally predictive of less engagement in cognitive restraint around food, but this relation, was not significantly for college students with ADHD. Findings from this study provide insight into intervention targets for college students with ADHD, ultimately resulting in significantly decreased societal and personal health costs. / M.S. / Emerging adulthood is a developmental period associated with increased engagement in health risk behaviors, particularly in college students with attention-deficit/hyperactivity disorder (ADHD), a disorder characterized by low distress tolerance and significant difficulty managing emotions.

Thesis (DTech (Environmental Health))--Cape Peninsula University of Technology, 2012. / Environmental pollution with persistent organic chemicals and inorganic trace metals is an increasingly important issue. Recently, a variety of chemicals are introduced in a very large scale on the surface water network. The main pathway of these pollutants into the environment was identified as wastewater treatment plants (WWTPs). The extended use of chemicals in many product formulations and insufficient WWTPs has lead to an increase in the levels of the detected micro-pollutants wastewater effluents. The majority of these compounds are characterized by a rather poor biodegradability. A large spectrum of pollutants present in waste as traces has been reported to exert adverse effects on human and wildlife. Even though compounds are found in wastewater in a very small amount, they may have the undesirable capability of initiating health effect on various high forms of life. This survey constitutes the first study in the City of Cape Town to report data for a variety of priority substances (phenols and phthalate esters) in WWTP effluents and receiving rivers. These results are of critical importance since the data generated are used to generate potential health risk associated with both the organic and inorganic compounds analyzed.

This study examined lifestyle changes as related to the risk of coronary heart disease (CHD) in Chinese students at Oregon State University (OSU). The study population included male students or scholars from the People's Republic of China who were attending OSU during spring term 1992. Fifty subjects were interviewed using a structured questionnaire. The questionnaire included eight categories of information: (1) bodyweight and blood pressure, (2) diet, (3) alcohol consumption, (4) cigarette smoking, (5) physical activity, (6) psychological stress, (7) acculturation factors, and (8) demographic factors. Results indicated that for this group of Chinese students, bodyweight, consumption of dietary fat, dairy products, soft drinks, and psychological stress had increased significantly during their stay in the US. Meanwhile, the level of physical activity had decreased. These changes, especially if continued, may have the potential to increase their risk of developing CHD. On the other hand, there were no significant changes in blood pressure and alcohol consumption. For cigarette smokers, smoking had decreased. In their responses to the open-ended questions, the reasons given for bodyweight changes included diet, decreased physical activity, and increasing age. Diet changes were attributed to food availability, relative price, and convenience. For decreased cigarette smoking, lack of smoking environment was considered to be the most important factor. Automobile use, limited spare time, and no friend to play with were the reasons for decreased physical activity. Finally, pressure in school, financial difficulty, and worrying about future were considered to be the reasons for increased psychological stress. Multiple regression analysis indicated that the length of US stay and decreased physical activity were significant predictors for bodyweight gain. The length of US stay was also a significant predictor for changes in total dietary fat. Having financial aid from school was associated with decreased physical activity. Living as single was significantly associated with increased psychological stress. This study failed to identify any significant associations between acculturation factors and changes in the CHD risk factors. / Graduation date: 1993

As the leading cause of death in the United States, coronary heart disease (CHD) is a growing public health problem, despite the fact that many risk factors for the disease are preventable, especially if addressed early in life. The purpose of the current study was to examine the effects of loss-framed versus gain-framed versus information-only health messages on both intention to attend and actual attendance at an appointment to get screened for CHD risk factors (i.e., hypertension, diabetes, and dyslipidemia). It was hypothesized that a population of young adults would be more likely to view screening for CHD risk factors as a low-risk, health-affirming behavior as opposed to a risky, illness-detecting behavior and would thus be more strongly influenced by gain-framed messages than loss-framed messages. Additional goals included the exploration of the extensively researched individual health beliefs of perceived threat (as defined by the health belief model) and health locus of control as they relate to message frames. One hundred forty-three undergraduate students were randomly assigned to either the loss-framed, gain-framed, or information-only control conditions. Framing manipulation checks revealed that participants failed to discern differences in the tone and emphasis of the experimental pamphlets. As a result, no tests of framing effects could be conducted. Sixteen (11.2%) of the 143 participants who participated in Part 1 of the experiment participated in Part 2 (i.e., attended a risk factor screening appointment). Multiple regression analysis revealed risk index, age, and powerful others health locus of control as significant predictors of screening intention. Gender was the only demographic or health related variable that was significantly related to screening outcome, such that women were more likely to get screened than men. Limitations and recommendations are discussed.

This study examined relationships among ethnic identity, gay identity, sexual sensation seeking, and HIV risk-taking behaviors among 302 men of color recruited from gay bars, bathhouses, community agencies, and the 1998 United States Conference on AIDS. The sample included 24% African American, 28% Latino, 25% Asian/ Pacific Islander, 19% Caucasian, 1% American Indian, and 3% other ethnicity. Logistic regression analysis identified sexual sensation seeking, having an undefined gay identity, being in a sexually exclusive relationship, not being HIV seronegative, and length of stay in the country (for those born overseas) as significant predictors of unprotected anal intercourse (insertive and penetrative) among men of color who have sex with men.
