Direct observation of the nutrition care practices of australian general practitioners

INTRODUCTION: Nutrition care refers to nutrition-related advice or counselling provided by health professionals in an attempt to improve the nutrition behaviour of patients

Patients' perceptions of their general practitioner's health and weight influences their perceptions of nutrition and exercise advice received

INTRODUCTION: General practitioners (GPs) play an important role in the management of patients who are overweight or obese. Previous research suggests that GPs' physical characteristics may influence patients' perceptions of health care received during consultations, mediating the likelihood of patients following health advice provided by GPs. This study aimed to explore patients' perceptions of their GP's health status and its influence on patients' perceptions of healthy eating and exercise advice

Impact of an undergraduate course on medical students' self-perceived nutrition intake and self-efficacy to improve their health behaviours and counselling practices

INTRODUCTION: Doctors are increasingly involved in the management of chronic disease and counsel patients about their lifestyle behaviours, including nutrition, to improve their health outcomes

Women experience the same ergogenic response to caffeine as men

This study aimed to determine if 1) consumption of caffeine improves endurance cycling performance in women, and 2) sex differences exist in the magnitude of the ergogenic and plasma responses to caffeine supplementation.Twenty-seven (11 women and 16 men) endurance-trained cyclists and triathletes participated in this randomized, double-blind, placebo-controlled, crossover study. Participants completed an incremental exercise test to exhaustion, two familiarization trials and two performance trials. Ninety minutes prior to the performance trials participants ingested opaque capsules containing either 3 mg·kg body mass of anhydrous caffeine or a placebo. They then completed a set amount of work (75% of peak sustainable power output) in the fastest possible time. Plasma was sampled at baseline, pre- and post-exercise for caffeine. Strict standardization and verification of diet, hydration, training volume and intensity, and for women, contraceptive hormone phase was implemented.Performance time was significantly improved following caffeine administration in women (placebo: 3863±419s, caffeine: 3757±312s; p=0.03) and men (placebo: 3903±341s, caffeine: 3734±287s;

Development of a validated questionnaire to measure the self-perceived competence of primary health professionals in providing nutrition care to patients with chronic disease

Background. Nutrition is an important aspect of chronic disease prevention and management by primary health professionals, including GPs, dietitians, practice nurses, diabetes educators and exercise professionals. In order to better understand how to improve the delivery of nutrition care, it is important to have valid and reliable tools to measure self-perceived competence

The effect of caffeine on repeat high intensity effort ability in rugby league players

Repeat high intensity efforts have recently been shown to occur at critical periods of rugby league matches. The purpose of this study was to examine the effect that caffeine has on repeat high intensity effort performance in semi-professional rugby league players

Dietary intake, body composition, and nutrition knowledge of Australian football and soccer players: implications for sports nutrition professionals in practice

Sports nutrition professionals aim to influence nutrition knowledge, dietary intake and body composition to improve athletic performance. Understanding the interrelationships between these factors and how they vary across sports has the potential to facilitate better-informed and targeted sports nutrition practice. This observational study assessed body composition (DXA), dietary intake (multiple-pass 24-hr recall) and nutrition knowledge (two previously validated tools) of elite and subelite male players involved in two team-based sports; Australian football (AF) and soccer. Differences in, and relationships between, nutrition knowledge, dietary intake and body composition between elite AF, subelite AF and elite soccer players were assessed. A total of 66 (23 ± 4 years, 82.0 ± 9.2 kg, 184.7 ± 7.7 cm) players participated. Areas of weaknesses in nutrition knowledge are evident (57% mean score obtained) yet nutrition knowledge was not different between elite and subelite AF and soccer players (58%, 57% and 56%, respectively, p > .05). Dietary intake was not consistent with recommendations in some areas; carbohydrate intake was lower (4.6 ± 1.5 g/kg/day, 4.5 ± 1.2 g/kg/day and 2.9 ± 1.1 g/kg/day for elite and subelite AF and elite soccer players, respectively) and protein intake was higher (3.4 ± 1.1 g/kg/day, 2.1 ± 0.7 g/kg/day and 1.9 ± 0.5 g/kg/day for elite and subelite AF and elite soccer players, respectively) than recommendations. Nutrition knowledge was positively correlated with fat-free soft tissue mass (n = 66; r2 = .051, p = .039). This insight into known modifiable factors may assist sports nutrition professionals to be more specific and targeted in their approach to supporting players to achieve enhanced performance

Seasonal Changes in Soccer Players' Body Composition and Dietary Intake Practices

Devlin, BL, Kingsley, M, Leveritt, MD, and Belski, R. Seasonal changes in soccer players' body composition and dietary intake practices. J Strength Cond Res 31(12): 3319-3326, 2017-The aims of this study were 2-fold: to determine seasonal changes in dietary intake and body composition in elite soccer players and to evaluate the influence of self-determined individual body composition goals on dietary intake and body composition. This longitudinal, observational study assessed body composition (total mass, fat-free soft tissue mass, and fat mass) using dual-energy x-ray absorptiometry and dietary intake (energy and macronutrients) via multiple-pass 24-hour recalls, at 4 time points over a competitive season in elite soccer players from one professional club in the Australian A-League competition. Self-reported body composition goals were also recorded. Eighteen elite male soccer players took part (25 ± 5 years, 180.5 ± 7.4 cm, 75.6 ± 6.5 kg). Majority (≥67%) reported the goal to maintain weight. Fat-free soft tissue mass increased from the start of preseason (55,278 ± 5,475 g) to the start of competitive season (56,784 ± 5,168 g; p < 0.001), and these gains were maintained until the end of the season. Fat mass decreased over the preseason period (10,072 ± 2,493 g to 8,712 ± 1,432 g; p < 0.001), but increased during the latter part of the competitive season. Dietary intake practices on training days were consistent over time and low compared with sport nutrition recommendations. The self-reported body composition goals did not strongly influence dietary intake practices or changes in body composition. This study has demonstrated that body composition changes over the course of a soccer season are subtle in elite soccer players despite relatively low self-reported intake of energy and carbohydrate

Objective: This study compared the level of prejudice against obese individuals (obesity bias) among final-year health and non-health students, and associated obesity education

Passive interventions in primary healthcare waiting rooms are effective in promoting healthy lifestyle behaviours: an integrative review

Primary healthcare waiting rooms have the potential to provide health-promoting environments to support healthy lifestyle behaviours such as smoking cessation, weight management and safe contraception. Passive interventions are cost-effective and continually available within an environment or setting, allowing individuals to interact, engage and learn about topics. The aim of this study was to undertake an integrative review to investigate the effectiveness of passive health-related waiting room interventions in improving healthy lifestyle behaviours, as well as precursors to behaviour change. The integrative review encompassed five phases: problem identification, literature search, data evaluation, data analysis and presentation of results. Quantitative, qualitative and mixed methods studies were included. Of the 9205 studies originally identified, 33 publications were included and grouped under four areas: knowledge about a health condition or behaviour, attitudes and intentions towards a health condition or behaviour, healthcare use and interactions, and health-related behaviours. Overall, the passive interventions had a general positive influence on knowledge, intentions, healthcare use and behaviours. Variable outcomes were reported regarding attitude towards a health topic. Few studies were assessed as both high quality and the highest suitability to assess effectiveness of interventions. Consideration of the clinical significance of improvements is warranted before implementation of future interventions. Overall, passive waiting room interventions appear to be effective in promoting healthy lifestyle behaviours
