OBJECTIVE: Renewed focus on public health has brought about considerable interest in workforce development among public health nutrition professionals in Canada. The present article describes a situational assessment of public health nutrition practice in Canada that will be used to guide future workforce development efforts. METHODS: A situational assessment is a planning approach that considers strengths and opportunities as well as needs and challenges, and emphasizes stakeholder participation. This situational assessment consisted of four components: a systematic review of literature on public health nutrition workforce issues; key informant interviews; a PEEST (political, economic, environmental, social, technological) factor analysis; and a consensus meeting. FINDINGS:Information gathered from these sources identified key nutrition and health concerns of the population; the need to define public health nutrition practice, roles and functions; demand for increased training, education and leadership opportunities; inconsistent qualification requirements across the country; and the desire for a common vision among practitioners. CONCLUSIONS: Findings of the situational assessment were used to create a three-year public health nutrition workforce development strategy. Specific objectives of the strategy are to define public health nutrition practice in Canada, develop competencies, collaborate with other disciplines, and begin to establish a new professional group or leadership structure to promote and enhance public health nutrition practice. The process of conducting the situational assessment not only provided valuable information for planning purposes, but also served as an effective mechanism for engaging stakeholders and building consensus. 相似文献

OBJECTIVES: The present paper aims to review and report on the current and predicted future public health nutrition workforce in South Africa. Additionally, it examines ways in which the Department of Health (DOH) is striving to meet the increasing burden of nutrition-related diseases in South Africa. METHODS: The primary sources of data used for the review were reports from the Census office, South African health reviews, mortality and morbidity statistics, and documents from the Health Professions Council of South Africa. RESULTS: There are fewer than 2000 registered dietitians in South Africa and fewer than 600 of them work in the public health sector. Furthermore, professional nurses - who are the backbone of the primary health-care system and deliver the rudiments of basic nutritional care - are not being trained in sufficient numbers to meet population growth; in 2004 there was only one nurse per 4000 persons. This situation is aggravated by the growing burden of conditions associated with both overnutrition and undernutrition, as well as the enormous demands of the HIV/AIDS epidemic. The DOH is striving to meet these increasing needs by means of the Integrated Nutrition Programme as well as a National Human Resources Plan which includes numerous strategies to improve the quantity and quality of health professionals' training, including dietitians and nutritionists. This plan includes the objective of increasing the public health nutrition workforce to more than 250 newly trained dietitians and nutritionists per annum by 2010. 相似文献

OBJECTIVE: To explore the nature, role and utility of mentoring in the development of competence in advanced-level Australian public health nutritionists. DESIGN: Qualitative study using in-depth interviews. SUBJECTS AND SETTING: Eighteen advanced-level public health nutritionists working in academic and practice settings in Australia. RESULTS: The attributes and career pathways of the subjects were consistent with previous findings. Dissatisfaction with clinical practice was a key reason for choosing a career in public health. Experiential learning, postgraduate education and mentoring from both peers and senior colleagues were the most significant contributors to competency development. The subjects supported mentoring as an important strategy for public health nutrition workforce development and articulated the characteristics and models important for mentoring relationships in public health nutrition. CONCLUSIONS: The present study suggests mentoring was an important part of competency development for advanced-level public health and community nutritionists in Australia. Mentoring programmes based on experiential learning may assist in developing public health nutrition workforce competence. 相似文献

BACKGROUND: In sub-Saharan Africa, underweight and micronutrient deficiencies account for an estimated 25% of the burden of disease. As the coverage of national health systems expands, increased opportunities exist to address the needs of children and women, the most vulnerable to these deficiencies, through high-quality nutrition services. OBJECTIVES: To assess health providers' knowledge and practice with regard to essential nutrition services for women and children in Burkina Faso, Mozambique and Niger, in order to assist the development of a standard guide and tools to assess and monitor the quality of the nutrition services delivered through national health systems. FINDINGS: The three surveys reveal the extent of missed opportunities to deliver nutrition services during routine prenatal, postnatal and child-care consultations for the prevention and treatment of highly prevalent nutritional deficiencies. CONCLUSION: A commitment to improving the quality of facility-based nutrition services is necessary to impact on the health outcomes of women and children 'covered' by national health systems. Rigorous assessment and monitoring of the quality of nutrition services should inform health programme and policy development. Building on the lessons learned in these three assessments, Helen Keller International has developed a standard Guide and Tools to assess the quality of the nutrition services delivered through national health systems. These tools can be adapted to assess ongoing nutrition services in health facilities, provide a framework for nutrition programming, inform the development of pre-service as well as in-service nutrition training curricula for providers, and evaluate the impact of nutrition training on providers' practices. 相似文献

OBJECTIVE: The aim of this study was to determine the food sources and acquisition practices used by homeless youth in Adelaide. This work is part of a larger study that aimed to examine the extent and nature of food insecurity among homeless youth. DESIGN: Cross-sectional design involving quantitative and qualitative methods. SETTING: Four health and welfare inner-city agencies serving homeless youth in Adelaide, South Australia. SUBJECTS: A sample of 150 homeless youth aged between 15 and 24 years recruited from these agencies. Fifteen were selected via snowball sampling for interview. RESULTS: Use of welfare food sources was high (63%). Food from welfare agencies was supplemented by unorthodox food acquisition methods such as theft (65%), begging for money for food (61%), begging for food items (44%) and asking for help from friends and relatives (34%). Reasons given for non-usage of welfare food services included affordability, access, being too busy, shame or embarrassment. CONCLUSIONS: Food insecurity is a salient issue for some homeless youth in Adelaide. Clarifying food acquisition practices of food-insecure homeless youth is essential for rational planning and improvement of food-related services to meet their needs. Such an understanding also underpins the development of broader public policy responses that improve individual and household skills and resources to acquire food and ensure food security. Nutrition professionals, welfare professionals and policy-makers need to work sensitively with welfare food agencies and others to improve food access and food security for homeless youth. 相似文献

There are few studies of community growth promotion as a means of addressing malnutrition that are based on longitudinal analysis of large-scale programmes with adequate controls to construct a counterfactual. The current study uses a difference in difference comparison of cohorts to assess the impact on the proportion of underweight children who lived in villages receiving services provided by the Senegal Nutrition Enhancement Project between 2004 and 2006. The project, designed to extend nutrition and growth promotion intervention into rural areas through non-governmental organisation service providers, significantly lowered the risk of a child having a weight more than 2 sd below international norms. The odds ratio of being underweight for children in programme villages after introduction of the intervention was 0.83 (95% CI 0.686, 1.000), after controlling for regional trends and village and household characteristics. Most measured aspects of health care and health seeking behaviour improved in the treatment relative to the control. 相似文献

OBJECTIVE: Food-based dietary guidelines (FBDGs) are globally promoted as an important part of national food and nutrition policies. They are presented within policy as key features of the strategy to educate the public and guide policy-makers and other stakeholders about a healthy diet. This paper examines the implementation of FBDGs in four countries: Chile, Germany, New Zealand and South Africa - diverse countries chosen to explore the realities of the FBDG within policy on public health nutrition. DESIGN: A literature review was carried out, followed by interviews with representatives from the governmental, academic and private sector in all four countries. RESULTS: In all four countries the FBDG is mainly implemented via written/electronic information provided to the public through the health and/or education sector. Data about the impact of FBDGs on policy and consumers' food choice or dietary habits are incomplete; nutrition surveys do not enable assessment of how effective FBDGs are as a factor in dietary or behavioural change. Despite limitations, FBDGs are seen as being valuable by key stakeholders. CONCLUSION: FBDGs are being implemented and there is experience which should be built upon. The policy focus needs to move beyond merely disseminating FBDGs. They should be part of a wider public health nutrition strategy involving multiple sectors and policy levels. Improvements in the implementation of FBDGs are crucial given the present epidemic of chronic, non-communicable diseases. 相似文献

In this article the authors discuss the concept of soil testing for organic farming and have identified a number of novel methods for estimation of potentially mineralizable nitrogen (N), microbial biomass nitrogen, speciation of biologically active phosphate fraction, and potassium. More so, modification in lime requirement, and cation balancing—a concept for cationic plant nutrition in organic farming are proposed. The present communication suggests an attribute designated “biological fertility index” combining both chemical and biological attributes for exploring the contribution of microbes toward soil fertility. Furthermore, the present article suggests technical approaches for carrying out research on identification of suitable extractants and their validation for robustness for formulating suitable protocols. Successful development of such soil testing protocol will be helpful to the personnel of state soil testing laboratories and organic certifying agencies presently lacking of such facilities. 相似文献

OBJECTIVES: This paper describes the development of an online questionnaire for testing nutrition professionals' perceptions of the 'healthiness' of individual foods and the results of administering that questionnaire. The questionnaire was designed to produce a standard ranking of foods that can be used as a tool for testing nutrient profile models. DESIGN: The questionnaire asked respondents to categorise 40 foods (from a master list of 120) in one of six positions, ranging from less to more healthy. The 120 foods were selected to be representative of the British diet. The questionnaire was sent via email to nutrition professionals from the British Dietetic Association and the (British) Nutrition Society. RESULTS: Eight hundred and fifty responses were received. These responses were used to rank the 120 foods by the average score which they received from the nutrition professionals. A regression analysis was also carried out to examine the relationship between the scores awarded by the nutrition professionals and various features of the foods: their nutritional content, their average serving size, their frequency of consumption, whether they were drinks or foods, etc. Nearly 50% of the variance in the average scores was explained by the nutritional content of the foods. When other variables were included in the analysis the percentage of variance that was explained increased to 64%. CONCLUSIONS: The average scores of the foods produce a standard ranking, which can be used as a tool for validating and comparing nutrient profile models. The regression analysis provides some information about how nutrition professionals rank the 'healthiness' of individual foods. 相似文献

OBJECTIVE: This study employed a multilevel design to test the contribution of individual, social and environmental factors to mediating socio-economic status (SES) inequalities in fruit and vegetable consumption among women. DESIGN: A cross-sectional survey was linked with objective environmental data. SETTING: A community sample involving 45 neighbourhoods. SUBJECTS: In total, 1347 women from 45 neighbourhoods provided survey data on their SES (highest education level), nutrition knowledge, health considerations related to food purchasing, and social support for healthy eating. These data were linked with objective environmental data on the density of supermarkets and fruit and vegetable outlets in local neighbourhoods. RESULTS: Multilevel modelling showed that individual and social factors partly mediated, but did not completely explain, SES variations in fruit and vegetable consumption. Store density did not mediate the relationship of SES with fruit or vegetable consumption. CONCLUSIONS: Nutrition promotion interventions should focus on enhancing nutrition knowledge and health considerations underlying food purchasing in order to promote healthy eating, particularly among those who are socio-economically disadvantaged. Further investigation is required to identify additional potential mediators of SES-diet relationships, particularly at the environmental level. 相似文献

Abstract The soil and plant analyses performed by the commercial laboratory while similar in many respects to the research or extension programs, vary from them in one or more of the following ways:(l) Results must be made available quickly to the grower. (2) Analyses have to be much more complete. (3) Many analyses of both soil and plant have to be made during the growing season. The frequency of sampling depends upon the plant, soil and climate, and (4) The commercial laboratory must show a profit to stay in business. It is often hampered in doing so by unfair competition of governmental agencies that provide such services free of charge or permit their employees to act as private consultants while holding a government job. 相似文献

OBJECTIVES: To review the impact of agriculture interventions on nutritional status in participating households, and to analyse the characteristics of interventions that improved nutrition outcomes. DESIGN: We identified and reviewed reports describing 30 agriculture interventions that measured impact on nutritional status. The interventions reviewed included home gardening, livestock, mixed garden and livestock, cash cropping, and irrigation. We examined the reports for the scientific quality of the research design and treatment of the data. We also assessed whether the projects invested in five types of 'capital' (physical, natural, financial, human and social) as defined in the Sustainable Livelihoods Framework, a conceptual map of major factors that affect people's livelihoods. RESULTS: Most agriculture interventions increased food production, but did not necessarily improve nutrition or health within participating households. Nutrition was improved in 11 of 13 home gardening interventions, and in 11 of 17 other types of intervention. Of the 19 interventions that had a positive effect on nutrition, 14 of them invested in four or five types of capital in addition to the agriculture intervention. Of the nine interventions that had a negative or no effect on nutrition, only one invested in four or five types of capital. CONCLUSIONS: Those agriculture interventions that invested broadly in different types of capital were more likely to improve nutrition outcomes. Those projects which invested in human capital (especially nutrition education and consideration of gender issues), and other types of capital, had a greater likelihood of effecting positive nutritional change, but such investment is neither sufficient nor always necessary to effect change. 相似文献

International experience of Policy Councils on food and nutrition has developed over recent decades but they have not received the attention that is due to them. The 1992 International Conference on Nutrition recommended that governments create Food Policy Councils but few have been created. There has been more experience in local and sub-national policy councils, particularly in North America. Developing country experience of attempting to improve food policy integration stems from the 1970s. The UK's House of Commons' (Parliamentary) Health Committee, in its 2004 report on obesity, reviewed current policy determinants of the rise in obesity, concluding that national food and health policy lacked coherence, integration and effectiveness. To address this vacuum, it proposed the creation of a new 'Council of Nutrition and Physical Activity to improve co-ordination and inject independent thinking into strategy'. The case for creating such a Council in the UK is reviewed, as are possible organisational options, functions and remit. A Council could be created under the forthcoming Public Health Act. The purpose of the new Council would be to provide independent advice and strategic advice as well as monitor the linkages between policies on food, nutrition and physical activity, noting their environmental implications. 相似文献

Throughout the 1990s, a variety of partnerships and community-based organizations have been formed with the primary mission to promote agricultural safety and health. These groups are altruistic, creative, energetic, and provide critical perspectives for improving the safety and health of the agricultural workforce at the local, regional, and national levels. These coalitions have been created as a result of philanthropic support, public funding, grassroots interest, and personal experiences with agricultural injuries andfatalities. They are playing important roles in collaborating with researchers and in reaching the individual agricultural communities. They have been instrumental in conducting needs assessments and are critical to the development and implementation of successful surveillance programs and interventions. Outreach and dissemination of research findings and other safety and health information to target audiences are strengths of these diverse coalitions. This article will focus on primarily community-based coalitions, providing an overview of the development, foci, membership activities, and contributions or impact of these groups during the 1990s and the challenges in maintaining and sustaining the coalitions. This information should be useful to those seeking to understand the activities of existing coalitions and identify potential partnerships for future activities. 相似文献

OBJECTIVES: To assess the level of consensus amongst an international panel of public health nutrition leaders regarding the essential competencies required for effective public health nutrition practice. DESIGN: A modified Delphi study involving three rounds of questionnaires. SUBJECTS: A panel of 20 public health nutrition experts from seven countries in the European Union, the USA and Australia. RESULTS: Expert panellists completed three rounds of the study relating to competencies. A literature review conducted as a prelude to the expert panel survey identified common competency units from the fields of public health, health promotion, nutrition and dietetics, and health education. These were categorised into seven competency areas including analytical, socio-cultural and political, public health service, communication, management and leadership, nutrition science and professional competency categories. There was strong initial agreement (> or = 90% of panellists at Round 1) that developing internationally recognised competencies for public health nutrition specialists was a priority. Twenty-six of an initial listing of 52 competency units were rated as essential competencies by > or = 80% of the panellists after Round 1. Iteration rounds resulted in the addition of five extra competency units suggested by panellists after Round 1 and an increase by 13 in the number of competencies rated as essential to consensus levels. From a total of 57 competency units rated after the final survey round, 41 competency units were rated as essential competencies by > or = 80% of the panellists (consensus), with 21 of these unanimously rated as essential competencies. CONCLUSIONS: There is strong international agreement amongst public health nutrition leaders in Europe, the USA and Australia about a range of competencies required for effective public health nutrition practice. Essential competency units identified can be used to develop and review competency standards for public health nutrition. 相似文献

OBJECTIVE: To study individual determinants of differential benefit from the Senegal Community Nutrition Project (CNP) by monitoring improvement in children's weight-for-age index (WA) or underweight status (WA < -2 Z-scores) during participation. DESIGN: A follow-up study using the CNP child monitoring data. Linear general models compared variations in WA according to 14 factors describing the beneficiaries and CNP services. SETTING: Poor neighbourhoods of Diourbel, a large city in Senegal, West Africa. Over a 6-month period, the CNP provided underweight or nutritionally at-risk 6-35-month-old children with monthly growth monitoring and promotion and weekly food supplementation, provided that mothers attended weekly nutrition education sessions. SUBJECTS: All the children who participated in the first two years of the project (n=4084). RESULTS: Mean WA varied from -2.13 (standard deviation (SD) 0.82) to -1.58 (SD 0.81) Z-scores between recruitment and the end of the follow-up. The lower the child's initial WA, the greater was their increase in WA but the lower was the probability of recovery from underweight. Only 61% of underweight children recovered. Six months of CNP services may not be sufficient for catch-up growth of severely underweight children. The number of food supplement rations received was not a direct indicator of the probability of recovery. After adjustment for services received and initial WA, probability of recovery was lower in girls, in younger children, in twins and when mothers belonged to a specific ethnic group. CONCLUSIONS: Determinants of benefit from CNP differed from the risk factors for underweight. Identification of participants with a lower probability of recovery can help improve outcome. Moreover, an explanation for the lack of recovery could be that many underweight children are stunted but not necessarily wasted. 相似文献
