Objective: The purpose of this study was to identify the psychosocial determinants of (1) intention to use dietary supplements (DS) and (2) the behavior of engaging in supplementation by testing the fit of the Theory of Planned Behavior (TPB). Methods: A total of 778 students at a Canadian university in Ontario completed a cross-sectional survey assessing participants' attitude, injunctive norm, descriptive norm, perceived behavioral control and intention toward DS use. Data were analyzed using independent sample t-tests and linear and logistic regressions. Results: Attitude, injunctive norm and perceived behavioral control were significant predictors of intention to use DS. Attitude, injunctive norm and intention were significant predictors of engaging in supplementation. The model explained 75.5% of the variance and correctly classified 89.6% of cases. The odds of using DS doubled with every one-unit increase in intention. Conclusions: This study confirms the utility of the TPB in predicting university students' supplementation habits.

Given the risks of inadvertent doping associated with dietary supplement (DS) use, it is critical to explore the extent of dependence of varsity athletes on DS to improve performance and support recovery. The purpose of this study was to gain insight into dietary supplementation practices among varsity athletes in a university setting in Ontario, Canada. An online DS use questionnaire was completed by 302 varsity athletes (30.5% male, 69.5% female; 20.5 ± 1.8-year old) who were competing in intermittent, power and endurance-based sports at the University of Guelph. The data from supplement users were analyzed using a Chi-square analysis to investigate type of DS consumption, frequency of use and reasons for use. Overall, 58.3% of athletes reported having used at least one type of DS in the past six months. Gender and age had significant associations with prevalence of DS use, with male athletes and athletes over 20-year old being more likely to be DS users. The most frequently reported reasons for consuming DS were to maintain good health, increase energy, promote recovery, correct or prevent micronutrient deficiencies and supply convenient forms of energy and/or macronutrients. Although, most athletes were using reliable sources of information, health care professionals, 58.6% still mentioned wanting to become more knowledgeable about DS. Findings from this study may guide the development of educational materials needed to address knowledge gaps on DS among varsity athletes. [ABSTRACT FROM AUTHOR]

Fueling Mexico: Energy and Environment, 1850-1950. Although Vergara covers some well-travelled ground, his energy-centric narrative offers new insights that will force scholars to reconceptualize modern Mexico. According to Vergara, oil transformed Mexico from an agrarian nation into an industrial one by fostering Import Substitution Industrialization, the "Mexican Miracle", the Green Revolution, rapid urbanization, a demographic explosion, and suburban sprawl.

Cancer is a disease that can have negative as well as some positive outcomes for the survivor, caregiver, and offspring. To date, there has been little research on the experiences of emerging adult offspring. When these offspring are also university students, they can experience unique challenges. In this phenomenological study, we explored the lived experience of parental cancer among emerging adult university students by interviewing 17 university students and using thematic analysis. The overarching themes were perceptions and beliefs about cancer, the outcomes of having a parent with cancer, influence of parental cancer on life as a university student, coping with having a parent with cancer, and attitudes and experiences around health and personal lifestyle. These results will be particularly useful to practitioners who provide services to university students experiencing parental cancer. [ABSTRACT FROM PUBLISHER]

Background: The purpose of this study is to develop and test the validity and reliability of a questionnaire to evaluate dietary supplement use based on the Theory of Planned Behaviour (TPB)., Methods: The questionnaire has sections on demographics, physical activity, dietary supplements, and cognitive constructs based on the TPB. Three stages are followed. In Stage 1, elicitation interviews are conducted on five varsity athletes, five physically active non-athletes, and five physically inactive University of Guelph (UofG) students. In Stage 2, comments and ratings of the TPB-based statements are gathered from 10 subject matter experts to check for content validity. In Stage 3, Cronbach's α is calculated to determine the internal consistency of the cognitive constructs by a pilot test on 84 Applied Human Nutrition UofG students., Results: Interviews assisted in the formulation of the cognitive constructs' statements, including intentions, attitudes, injunctive norms, descriptive norms, and perceived behavioural control. Content validity ensured that these constructs did not overlap. Few statements from the cognitive constructs were omitted based on findings from the reliability test, achieving acceptable Cronbach's α values across all constructs (≥0.70)., Conclusions: This supplement use questionnaire will be used in a future study to investigate the use and determinants of dietary supplements among Canadian athlete and non-athlete UofG students.

Dog walking is beneficial to dogs and their owners, and it supports One Health, an initiative devoted to improving the health of animals and humans. Despite the benefits of dog walking, many dogs and their owners are not engaging in adequate dog-walking exercise. One way to encourage dog walking is for veterinarians to counsel owners on dog walking during veterinary appointments. This pilot study used individual in-person or telephone interviews to understand veterinarians' perceptions of and experiences with counseling about dog walking in companion animal practice. Seventeen veterinarians licensed to provide canine care in Ontario participated in an interview in 2015. Thematic analysis was used to analyze the interview transcripts. Participants thought dog walking was important for both dogs and owners and discussed physical, social, and mental benefits of dog walking. Participants described barriers to dog-walking counseling including dog owners' lack of compliance or physical condition, dogs' behavior, and lack of time or low priority during appointments. Also, participants discussed how dog walking was not addressed in their professional veterinary education. These findings can be used to educate veterinary students and practicing veterinarians on the value of dog walking for people and dogs and the barriers they may face when counseling clients about dog walking.
