INTRODUCTION: Household food gatekeepers have the potential to influence the food attitudes and behaviours of family members, as they are mainly responsible for food-related tasks in the home. The aim of this study was to determine the role of gatekeepers' confidence in food-related skills and nutrition knowledge on food practices in the home.

METHODS: An online survey was completed by 1059 Australian dietary gatekeepers selected from the Global Market Insite (GMI) research database. Participants responded to questions about food acquisition and preparation behaviours, the home eating environment, perceptions and attitudes towards food, and demographics. Two-step cluster analysis was used to identify groups based on confidence regarding food skills and nutrition knowledge. Chi-square tests and one-way ANOVAs were used to compare the groups on the dependent variables.

RESULTS: Three groups were identified: low confidence, moderate confidence and high confidence. Gatekeepers in the highest confidence group were significantly more likely to report lower body mass index (BMI), and indicate higher importance of fresh food products, vegetable prominence in meals, product information use, meal planning, perceived behavioural control and overall diet satisfaction. Gatekeepers in the lowest confidence group were significantly more likely to indicate more perceived barriers to healthy eating, report more time constraints and more impulse purchasing practices, and higher convenience ingredient use. Other smaller associations were also found.

CONCLUSION: Household food gatekeepers with high food skills confidence were more likely to engage in several healthy food practices, while those with low food skills confidence were more likely to engage in unhealthy food practices. Food education strategies aimed at building food-skills and nutrition knowledge will enable current and future gatekeepers to make healthier food decisions for themselves and for their families.

Background: Although there is increasing recognition that quality of life (QOL) and health-related quality of life (HRQOL) are important outcome variables in clinical trials for children with cerebral palsy, there are substantial limitations in existing measures of QOL. This study identify themes of QOL for children with cerebral palsy and their parents to guide the development of a new condition-specific QOL scale. Methods: A qualitative study of parent and child views on QOL composition was conducted, using a grounded theory framework. Families participated in semistructured interviews on QOL until thematic saturation was reached (n = 28 families). Results: Overall, 13 themes emerged from the interviews: physical health, body pain and discomfort, daily living tasks, participation in regular physical and social activities, emotional well-being and self-esteem, interaction with the community, communication, family health, supportive physical environment, future QOL, provision of, and access to services, financial stability, and social well-being. Conclusions: Research with parents and children with cerebral palsy, representative of severity across the disease spectrum and socio-economic status, reinforced and expanded on the traditional themes that have underpinned QOL measurement development. This has implications not only for the development of a new QOL scale for children with cerebral palsy, but also for clinical interventions and community care management.

The role of dietary factors in the development of skin cancer has been investigated for many years; however, the results of epidemiologic studies have not been systematically reviewed. This article reviews human studies of basal cell cancer (BCC) and squamous cell cancer (SCC) and includes all studies identified in the published scientific literature investigating dietary exposure to fats, retinol, carotenoids, vitamin E, vitamin C, and selenium. A total of 26 studies were critically reviewed according to study design and quality of the epidemiologic evidence. Overall, the evidence suggests a positive relationship between fat intake and BCC and SCC, an inconsistent association for retinol, and little relation between ß-carotene and BCC or SCC development. There is insufficient evidence on which to make a judgment about an association of other carotenoids with skin cancer. The evidence for associations between vitamin E, vitamin C, and selenium and both BCC and SCC is weak. Many of the existing studies contain limitations, however, and further well-designed and implemented studies are required to clarify the role of diet in skin cancer. Additionally, the role of other dietary factors, such as flavonoids and other polyphenols, which have been implicated in skin cancer development in animal models, needs to be investigated.

Nurses are increasingly incorporating complementary therapies into their practices. Aromatherapy is one of the most popular therapies. The basis of aromatherapy is essential oils, which are chemically active substances with a long history of safe traditional use and a growing evidence base to support their use in nursing care. In Australia, essential oils are classified and regulated under the same policies as conventional medicines such as the National Medicines Policy and the Quality Use of Medicines (QUM) framework applies. QUM is a framework for selecting and using medicines safely and effectively if medicines are indicated. The key elements of QUM are a systems-based approach to using medicines based on relevant evidence, partnerships, and informed client consent. Clients are placed at the centre of a QUM medication management process, which is consistent with holistic care. Applying a QUM approach to essential oil use, Quality Use of Essential Oils (QUEO), involves developing effective systems for managing essential oils from an holistic perspective that includes structured assessment and diagnostic processes to enable effective essential oil prescribing and outcome monitoring. In a QUEO approach, essential oils are integrated into the client's overall medication regimen and care plan rather than being used as ‘add-ons’. Adopting QUEO is consistent with the current national focus on the quality use of therapeutic substances, increases the profile of aromatherapy in nursing care and provides important information to guide future aromatherapy practices.

Despite increased concern for the health related quality of life (HRQOL) of people with disabilities, little is known about the HRQOL of children with developmental disabilities. The present study aimed to explore the HRQOL of children who were at risk or having developmental disabilities in Hong Kong. Using the parent-reported Chinese Pediatric Quality of Life Inventory (PedsQL), the HRQOL of 173 children (2–4 years) with signs of delays in development was contrasted with that of 132 children with typical development. We found that those who exhibited high risk of developing a developmental disability had significantly lower overall well-being (76.3 ± 13.7 vs. 84.2 ± 11.3; p<0.001) and psychosocial health (71.3 ± 15.6 vs. 82.5 ± 12.9; p<0.001) but not necessarily physical health. The findings are consistent with previous findings in children with different disabilities and chronic illnesses. They suggest children at risk or having DDs need help in restoring their quality of life up to the standard experienced by their healthy peers, particular in psychosocial aspects such as social functioning, emotion functioning, and school functioning.

Preventing the development of obesity in children is an international health priority. To assess the effectiveness of interventions designed to prevent obesity, promote healthy eating and/or physical activity and/or to reduce sedentary behaviours in 0–5-year-old children, a systematic review of the literature was performed. Literature searches were limited to articles published between January 1995 and June 2006, printed in English and sampling children aged 0–5-years. Searches excluded literature concerned with breastfeeding, eating disorders, and interventions which were school-based or concerned with obesity treatment. Two reviewers independently extracted data and assessed study strengths and weaknesses. Nine included studies were grouped based on the settings in which they were delivered. Most studies involved multi-approach interventions, were conducted in the USA and varied in study designs and quality. All showed some level of effectiveness on at least one obesity-behaviour in young children. These studies support, at a range of levels, the premise that parents are receptive to and capable of some behavioural changes that may promote healthy weight in their young children. The small quantity of research heralds the need, particularly given the potential for early intervention to have long-lasting impacts on individual and population health, to build in a substantial way upon this evidence base.

The purpose of this study was to explore the effect of physical disabilities (PD) on the quality of life (QoL) of adolescents aged from 10 to 18 years. Sixty-three adolescents with PD (aged 14.9 ± 2.4 years) from primary (5th grade or above) to high schools in Kaohsiung City volunteered to participate in this research; 282 children without disability (aged 13.8 ± 2.3 years) attending schools in the same geographical region were recruited as controls. The Student Version of the Comprehensive Quality of Life Scale was used in this study. This is a multidimensional self-report, global measure of subjective and objective QoL. Multivariate analysis of variance revealed that the two groups were significantly different in objective QoL (F = 11.53, p < 0.001). Material wellbeing was substantially lower in the PD group when compared to the control group. In contrast, domains such as productivity, safety, and emotion were higher in the PD group. Among the subjective scales, the PD group showed higher productivity and better emotion when compared to the control group. No significant correlation was observed between objective and subjective overall QoL scores (r = 0.20, p = 0.12) in the PD group. These findings showed that subjects with PD in regular schools demonstrated different patterns in objective and subjective QoL when compared to those without PD. Both subjective and objective domains are important when measuring QoL of adolescents with PD.

This experiment was conducted to examine the effect of feeding small, isoenergetic amounts of supplements containing high protein and functional lipid components, rather than the greater amounts of cereal and/or legume grains usually fed during the dry season in Australia, on dry matter intake (DMI), growth performance, plasma metabolites, and fat deposition in lambs consuming low quality roughage. Thirty two crossbred wether lambs ([Merino × Border Leicester] × Poll Dorset) were divided into four groups by stratified randomization according to liveweight (26–33 kg). After a 7-day adaptation to a hay diet (lucerne hay:oaten hay; 30:70), lambs were allocated to four treatments consisting of (1) basal diet of lucerne hay:oat hay (20:80; metabolizable energy (ME) = 7.0 MJ/kg DM), Basal; (2) basal + canola meal (84 g per day), CM; (3) basal + soymeal (75 g per day), SM; or (4) basal + fishmeal (80 g per day), FM. Daily hay and supplement DMI, and weekly liveweight were recorded during a 53-day experimental study. Blood samples were taken on day 1 and pre- and post-feeding on days 30 and 53 to measure changes in plasma glucose and plasma urea nitrogen (PUN) concentration. At the end of the experiment, lambs were slaughtered and hot carcass weight (HCW) recorded; cold carcass fatness (total muscle and adipose tissue depth at 12th rib, 110 mm from midline; GR) was determined at 24 h postmortem. Total DMI was increased (P < 0.001) in CM, SM and FM treatments, but basal hay DMI intake was only increased (P < 0.01) in CM and FM treatments compared with Basal treatment. This resulted in significant (P < 0.01) increases in metabolizable energy (ME) and crude protein (CP) intakes in all supplemented treatments, with the highest intakes recorded in the FM treatment. Liveweight gain (LWG) was significantly increased in CM and SM (P < 0.05) and FM (P < 0.01) treatments but HCW was significantly (P < 0.01) heavier slaughter only in the FM treatment. Feed conversion efficiency (P < 0.001) and GR fat at depth (P < 0.05) was reduced in all supplement treatments compared with Basal. Plasma glucose concentration was significantly (P < 0.05) increased after feeding in all treatments but there was no treatment effect. PUN was significantly increased over time in the supplemented treatments compared with the Basal treatment; there was no significant difference between supplement treatments by day 53. Results show that feeding small amounts of high protein and lipid-containing supplements improves production responses and are beneficial in producing carcasses with more lean compared with carcasses from lambs fed a low quality hay diet.

In two experiments, each with 32 crossbred ([Merino x Border Leicester] x Poll Dorset) wether lambs (26 to 33 kg weight range), animals were randomly assigned to one of four treatments. A mixture of lucerne chaff:oaten chaff was used as a basal diet, offered in different ratios. Animals were allowed to consume on a free-access basis in Exp. 1 or 90% of ad libitum intake in Exp. 2 in order to provide a low- (6.5 MJ ME/d) and medium- (9.5 MJ ME/d) quality basal diet, respectively. Isoenergetic amounts of lipid supplements, fish meal (80 g DM), canola meal (84 g DM), and soy meal (75 g DM) were tested in Exp. 1. In Exp. 2, fish meal (9% DM), unprotected rapeseed (7% DM), and protected canola seed (6% DM) were fed as supplements. At the end of 53-d (Exp. 1) or 46-d (Exp. 2) experimental periods, lambs were slaughtered at a commercial abattoir and at 24 h postmortem longissimus thoracis (LT) muscle was collected for the analysis of fatty acid (FA) composition of structural phospholipid and storage triglyceride fractions. Fish meal diet increased LT muscle long-chain n-3 FA content by 27% (P < 0.02) in Exp. I and 30% (P < 0.001) in Exp. 2 compared with lambs fed the basal diet, but fish meal decreased (P < 0.01) the n-6 FA content only in Exp. 1. Soy meal and protected canola seed diets increased (P < 0.01) LT muscle n-6 FA content but did not affect long-chain n-3 FA content. Longissimus thoracis muscle long-chain n-3 FA were mainly deposited in structural phospholipid, rather than in storage triglyceride. In both Exp. 1 and Exp. 2, the ratio of n-6:n-3 FA in LT muscle was lowest (P < 0.01) in lambs fed fish meal supplement compared with all other treatments. Protected canola seed diet increased the ratio of n-6:n-3 FA (P < 0.01) and PUFA:saturated fatty acid (P < 0.03) content from those animals fed the basal, fish meal, and unprotected rapeseed diets in Exp. 2. This was due to an increase in muscle n-6 FA content, mainly linoleic acid, of both phospholipid (P < 0.001) and triglyceride (P < 0.01) fractions and not to an increase in muscle n3 FA content. The results indicate that by feeding fish meal supplement, the essential n-3 FA can be increased while lowering the ratio of n-6:n-3 content in lamb meat to an extent that could affect nutritional value, attractiveness, and the economic value of meat.

The effects of dietary manipulation of muscle long-chain omega-3 fatty acids (FA) on sensory properties of cooked meat in second cross ([Merino×Border Leicester]×Poll Dorset) wether lambs were evaluated. Lambs fed dietary supplements of fish meal (FM, Exp. 1) and fish oil (FO, Exp. 2) showed moderately (P<0.01) and markedly (P<0.001) increased muscle long-chain omega-3 FA content compared with those fed the basal diet of lucerne chaff and oat chaff. Protected canola seed (PCS, Exp. 1) significantly (P<0.001) increased omega-6 FA content of the longissimus muscle. In each of the 2 experiments (1 and 2), after being fed experimental diets for 6 weeks lambs were slaughtered at a commercial abattoir. At 24 h post-mortem (PM) the semitendinosus and biceps femoris muscles were removed from animals and stored at −20°C until evaluation of sensory properties using experienced panel members. The muscle samples were stored for 3 (Exp. 1) and 12 (Exp. 2) months then removed, thawed and cooked for sensory evaluation. The meat samples were cooked under standardized conditions in a convection microwave at 180°C (20–25 min) to an internal temperature of 75°C. Cooked samples were tested for flavour, aroma, juiciness and overall palatability. The significant increase in muscle long-chain omega-3 with FM (Exp. 1 and 2) and FO (Exp. 2) or omega-6 FA with PCS (Exp. 1) were not detrimental to sensory panel evaluations of flavour or aroma of cooked meat when compared with the basal diet. However, meat from FM (Exp. 1) had lower juiciness and FO (Exp. 2) had lower overall palatability. Protected sunflower meal protein with FO (Exp. 2) significantly lowered ratings for flavour, juiciness and overall palatability. Lamb meat with increased levels of long-chain omega-3 FA can be produced without altering the sensory quality (flavour or aroma) of the cooked meat.

A 12-week feeding trial was undertaken to evaluate the effects of partial replacement of marine raw materials in the diet with soybean meal and beef tallow on growth and product quality of European eel (Anguilla anguilla ). Based on growth, feed efficiency and chemical composition, soybean meal was found to be an unsuitable ingredient for eel diets as a substitute for fishmeal (25% on a protein basis), probably because of the low digestibility of its carbohydrate content. However, beef tallow can be used to replace 50% of fish oil without reduction in growth, provided that digestible carbohydrates are present in the diet. No major effects of protein and lipid sources in the diet were found on fillet chemical composition. Sensory analysis revealed no significant differences between fish fed the control and the experimental diets, with the exception of salty taste which was significantly higher in fish fed combined soybean meal and beef tallow compared with fish fed the control diet.

Aims
The aims of this study was to determine whether quality of life for people 65 years and over is affected by constipation and laxative use and to identify dimensions or functions of quality of life that were specifically affected by constipation.

Method
Of the 79 subjects who completed the pre-screening questionnaire to determine their bowel function and laxative use status , 58 agreed to participate in the phase of the study (73%) of which 22 were females and 36 were males. Subjects completed a quality of life questionnaire, comprising of ComQoL questions and SF36 questions during a face to face interview conducted in their own homes.

Results
ComQoL importance and satisfaction scores were compared by bowel health status and gender. The most important dimensions for all subjects were health (mean score 9.4), family (mean score 9.3) and their own happiness (mean score 8.7). The total mean for satisfaction score for the whole group was 69%, fractionally lower that the bottom end of the normative range (70-80%). Constipated subjects scored satisfaction with their health significantly lower than the not constipated group (p =0.02) and subjects who took laxatives once a fortnight or more also had significantly lower satisfaction with their health (p=0.03).

Conclusion
Overall the subjects reported a high level of satisfaction with their lives, constipation and laxative use affected their satisfaction with their health. Further exploration is needed to determine how this will affect lifestyle and health behaviours.

This study aimed to examine cost disparity and nutritional choices within the
City of Yarra (Yarra), targeting three suburbs that have low- and high-rise
estates: Richmond, Fitzroy, and Collingwood. The healthy food basket
(HFB) was modeled on the Queensland Healthy Food Access Basket for a
six-person family for a fortnight and was constructed to include food items
that are common to ethnic groups living in Yarra. The HFB food item costs
were sampled across 29 food outlets in Yarra. The average cost of HFB per fortnight
for a family of six was significantly lower in Richmond (Mean = $419.26)
than in Collingwood (Mean = $519.28) and in Fitzroy (Mean = $433.98). While
costs for cereal groups, dairy, meats and alternatives, and non-core were
comparable across the suburbs, significant differences were noticed for fruit,
legumes and vegetables. Geographic location alone explained 54% of the
variance in HFB price (F2,26 = 15.23, p < 0.001) and 32.7% in the variance of
fruit, vegetable and legumes (F2,26 = 7.72, p < 0.001). The effect of geographic
location remained consistent after controlling for the type of food
outlets. The type of food outlets had a non-significant effect on the variance
of prices. Richmond had a greater number variety of fruit, vegetables, and
legumes (F2, 26 = 5.7, p < 0.01) and an overall lower number of missing items
(F2, 26 = 3.9, p < 0.05) than Collingwood and Fitzroy. The diversity of food
available in the three suburbs was more likely to reflect the Vietnamese,
Chinese and East-Timorese shopping pattern than the rest of other ethnic

There is much interest in the nature and quality of the diet consumed by adolescents. To determine whether there are significant associations between diet and gain in height and weight in this age group, the present study analysed data on food intake and weight and height obtained on three occasions over a 30-month period from a total of 326 adolescents aged between 12 and 15 years. Information on sociodemographic and other lifestyle factors, including an indicator of physical activity, was also obtained. Energy intake was found to be a significant positive predictor of both height and weight gain. In addition intake of fat, calcium and riboflavin were found to be significant positive predicators of height gain and intake of carbohydrate and starch significant positive predictors of weight gain. After controlling for energy intake only riboflavin approached significance as a positive predictor of height gain. A food group analysis identified intake of dairy foods as a significant predictor of height gain. Although statistically significant the dietary predictors explained only a small proportion of the variability in height and weight (≤3.5%). Given the difficulties in obtaining complete dietary records from this age group and the generally adequate nature of the diet in the study group, the small proportion of height and weight gain explained by diet is not unexpected. Nevertheless the nutrient predictors identified are consistent with nutrient requirements for growth during adolescence and highlight the importance, for this age group, of an adequate intake of nutrients specifically provided by dairy foods. Few significant associations were found between growth rates and the sociodemographic and the lifestyle factors measured in this study. The ethnic diversity of the study sample may have contributed to this outcome.

Abstract The purpose of this study was to identify place-specific dimensions of service quality in spectator sport settings and determine if the importance of these dimensions differed across cultures. The study was limited to the soccer industry and involved the collection of responses from identified soccer spectators to a range of items presented in a survey instrument. The survey was distributed to respondents face-to-face on a match day of the club they supported, or mailed to their home address. Responses were obtained from spectators from two clubs from Australia (n=277), one club from the USA (n=199), one club from the Netherlands (n=245) and one federation from Malaysia (n= 100). Based on the findings of a number of authors, six categories of potential place-specific dimensions of service quality in spectator sport settings were created and the research instrument contained a number of items that could be categorised under one of these headings. These categories were Home, Religion, Social facilitation, Sensory, Uncertainty of outcome, and Personal attention. In this thesis it was assumed that place-specific service quality issues are similar for sport spectators of different cultures, although differences in degree of importance of these dimensions (etic approach) were likely to emerge. In other words, although it was expected dimensions per country to be similar, differences in degree of importance of these dimensions were expected. Given the lack of confirmatory statistical evidence pertaining to the specific country samples, it was concluded that differences per country are likely to be more than just differences in degree. Both the overall structure and structures per country could not be confirmed, and hence the conclusion was drawn that differences in nature between the countries were present. In other words, what is a dimension of place-specific service quality in one country is not necessarily a dimension in another country. The results of a content analysis of ‘core component’ structures per country compared with a (full sample) core component structure delivered six components (referred to as place-specific dimensions of service quality) that were defined as Home, Hedonist, Religious follower, Safe atmosphere, Hospitality and Personal Attention. It was found that in most cases the cultural orientation of soccer spectators reflects the cultural orientation of the country as a whole as proposed by Hofstede (1991). However, in line with Huntington (1997), it was also argued that grouping people based on their country of origin as a proxy for their cultural orientation, will increasingly lead to flawed and incomplete research findings. As noted by Yoo etal. (1999), the identification of a person's cultural orientation is likely to deliver more direct results when measured at the individual level In that regard it is concluded that it may seem prudent to view Hofstede's dimensions of culture with increased conceptual scrutiny. Although having been replicated in multiple studies, it becomes increasingly unlikely that Hofstede's dimensions cover the complete spectrum of an individual person's cultural orientation. In conclusion, this study identified that soccer spectators (from a number of clubs) from Australia, the USA, the Netherlands and to a lesser extent Malaysia, perceive a range of place-specific service quality dimensions in spectator spoil settings to be important when visiting a soccer match. Before research into satisfaction with and value of place-specific dimensions of the spectator sport service product is initiated, it is pertinent the identified dimensions are further explored and confirmed in different country (culture) settings. The confusion that still exists about the place of the value concept (in relation to quality and satisfaction), where Holbrook (1994) defines quality as a type of value and Chelladurai and Chang (2000) argue that value is a type of quality, further underpins this necessity. It needs to be clear what are the targets of service quality before this information is integrated in larger holistic research frameworks. In the final section of the thesis a conceptual model for international services marketing research in the sport industry was presented as a first attempt to integrate the findings of this research and other researchers.
