Whereas common infectious and parasitic diseases such as malaria and the HIV/AIDS pandemic remain major unresolved health problems in many developing countries, emerging non-communicable diseases ...relating to diet and lifestyle have been increasing over the last two decades, thus creating a double burden of disease and impacting negatively on already over-stretched health services in these countries. Prevalence rates for type 2 diabetes mellitus and CVD in sub-Saharan Africa have seen a 10-fold increase in the last 20 years. In the Arab Gulf current prevalence rates are between 25 and 35% for the adult population, whilst evidence of the metabolic syndrome is emerging in children and adolescents. The present review focuses on the concept of the epidemiological and nutritional transition. It looks at historical trends in socio-economic status and lifestyle and trends in nutrition-related non-communicable diseases over the last two decades, particularly in developing countries with rising income levels, as well as the other extreme of poverty, chronic hunger and coping strategies and metabolic adaptations in fetal life that predispose to non-communicable disease risk in later life. The role of preventable environmental risk factors for obesity and the metabolic syndrome in developing countries is emphasized and also these challenges are related to meeting the millennium development goals. The possible implications of these changing trends for human and economic development in poorly-resourced healthcare settings and the implications for nutrition training are also discussed.
Dissemination of research findings through the publication of one’s work or a group of contributors is an important part of the research process, as this allows the passing on of benefits to a much ...wider community. In whatever evocative form this dissemination may take, the onus lies on the author(s) to ensure adherence to the code of ethics as it pertains to the integrity of the information being put out. We publish because we want our findings to be adapted into practice and application, or in some cases may be relevant to policy makers in decision-making. To a large extent in the field of academia, successful publication improves opportunities for academic funding and promotion whilst enhancing scientific and scholarly achievement and repute. A situation may be compromised where intellectual contributions to a scientific investigation do not adhere to the four key guidelines of scholarship, authorship, approval and agreement as well as the protocols of ensuring good publication ethics. The objective of this review is to lay emphasis on universal standards for manuscript authorship and to fostering good practices. This in our view will bring authorship credit and accountability to the attention of our colleagues and readers at large. To achieve this, a systematic and critical review of the literature was undertaken. Electronic databases, academic journals and books from various sources were accessed. Several key search terms relating to responsible authorship, common authorship malpractices, conflict of interest, universal publication guidelines and other authorship related issues, were used. Only references deemed useful from relevant texts and journal articles were included. In this paper, the authors have sought to highlight the pitfalls researchers sometimes entangle themselves within an act of compromise thereby impinging on the ethical and professional responsibilities for the content of a paper under consideration. This article presents the case that authorship has a strong currency that brings not only personal satisfaction but also career rewards based on publication counting. In all cases described here, a universal standard for manuscript authorship will be critical in fostering good practices. As you write and review manuscripts, keep these good practices in mind, and consider ways to bring authorship credit and accountability to the attention of your colleagues and readers.
Childhood malnutrition still remains a major public health problem impacting negatively on the academic aptitude of school-aged children (SAC) particularly in limited resource countries. The ...Government of Ghana in collaboration with the Dutch Government introduced the school feeding programme (SFP) to boost the nutritional status of SAC in the country. This study sought to compare the nutritional status of SAC enrolled in schools with the SFP and SAC enrolled in schools without the SFP in place for the purpose of identifying which group has the higher rate of malnutrition.
A multi-stage sampling was used to select 359 SAC between 5 and 12 years who are enrolled in primary one to six. Twelve public schools were selected, of which 6 schools benefit from the SFP and the other six do not. Anthropometric measurements were conducted for the subjects and SPSS version 20.0 was used for data entry and analysis. Chi square test was carried out to determine the difference between the two groups of schools.
Of the total of 359 subjects, 55.1% were from schools that do not implement the SFP and 44.9% were from schools that implement the SFP. The prevalence of stunting among children in schools on the SFP was 16.2% compared with 17.2% among children in schools that do not implement the SFP. The prevalence of thinness was two times higher (9.3%) among children in schools on the SFP than in children in schools that do not implement the SFP (4.6%) (p = 0.028). The prevalence of overweight among children in schools on the SFP was 1.9% and 0.0% for children in schools that do not implement the SFP. Sub district, sex, age of pupil, area of residence and community type were significantly associated with stunting (p = 0.002), (p = 0.008), (p = 0.008), (p < 0.001) and (p = 0.007) respectively.
Overweight and thinness were higher among children in schools on SFP than in children in schools without SFP. An evaluation of the implementation of the school feeding programme is recommended for future studies.

This study developed, validated, and evaluated a framework of factors influencing dietary behaviours in urban African food environments, to inform research prioritisation and intervention development ...in Africa. A multi-component methodology, drawing on concept mapping, was employed to construct a framework of factors influencing dietary behaviours in urban Africa. The framework adapted a widely used socio-ecological model (developed in a high-income country context) and was developed using a mixed-methods research approach that comprised: i. Evidence synthesis consisting of a systematic review of 39 papers covering 14 African countries; ii. Qualitative interview data collected for adolescents and adults (n = 144) using photovoice in urban Ghana and Kenya; and iii. Consultation with interdisciplinary African experts (n = 71) from 27 countries, who contributed to at least one step of the framework (creation, validation/evaluation, finalisation). The final framework included 103 factors influencing dietary behaviours. Experts identified the factors influencing dietary behaviours across all the four levels of the food environment i.e. the individual, social, physical and macro levels. Nearly half (n = 48) were individual-level factors and just under a quarter (n = 26) were at the macro environmental level. Fewer factors associated with social (n = 15) and physical (14) environments were identified. At the macro level, the factors ranked as most important were food prices, cultural beliefs and seasonality. Factors ranked as important at the social level were household composition, family food habits and dietary practices. The type of food available in the neighbourhood and convenience were seen as important at the physical level, while individual food habits, food preferences and socioeconomic status were ranked highly at the individual level. About half of the factors (n = 54) overlap with those reported in an existing socio-ecological food environment framework developed in a high-income country context. A further 49 factors were identified that were not reported in the selected high-income country framework, underlining the importance of contextualisation. Our conceptual framework offers a useful tool for research to understand dietary transitions in urban African adolescents and adults, as well as identification of factors to intervene when promoting healthy nutritious diets to prevent multiple forms of malnutrition.

Heightened by the epidemiological transition associated with excess energy intake, sedentary lifestyle and urbanisation, metabolic syndrome (MetS), previously uncommon in sub-Sahara Africa, is ...increasingly becoming a public health concern.
We retrospectively assessed the association of diet and socio-demographic indicators as exposure factors to the development of MetS in typical peri-urban and rural settings in Ghana and examined the effect of MetS on the perceived quality of life of patients. One-on-one age- and sex-matched case-control study involving 152 adults aged 45–65 years were recruited from a diabetic clinic. Controls were recruited from communities where cases resided. Case definition was concurrent adiposity, hypertension, diabetes and dyslipidaemia. Lifestyle was assessed using a lifestyle and habits questionnaire, whereas diet history was assessed using a food frequency questionnaire. Differences were tested using McNemar and paired t-tests. To determine which exposure variables significantly predicted the development of MetS, we conducted a conditional logistic regression and reported the Mantel Haenszel crude and adjusted odds ratio (OR).
Markers for MetS among the cases and controls were abdominal obesity (98.7% vs 36.8%), hypertension (90.8% vs 2.6%) and diabetes (72.4% vs 1.3%). Controls (77.6%) consumed more diversified diets compared to the cases (10.5%) (p = 0.001). Lower risk for MetS was linked to secondary education (COR = 0.17) and long duration of residence (COR = 0.30) in a peri-urban setting (COR = 0.22) whereas being unemployed (COR = 9.00) increased the risk. Abdominal obesity (COR = 28.51) was a stronger predictor of MetS compared to BMI ≥30 kg/m2 (COR = 14.80). Comparatively, the controls had a better self-perception of their physical wellbeing (73.7% vs 2.6%), fitness (88.2% vs 13.2%), nutrition and weight control (14.5% vs 1.3%) and psychological health (19.7% vs 0%).
Considering that socio-demographic indicators were key exposures to MetS, we recommend interventions that promote the holistic wellbeing of the individual and should be integrated into existing health, social and community-based support services.
•Unlike developed countries, the rate of metabolic syndrome in transition countries and the effect on the quality of life is not well known.•Lack of formal education and dwelling in a rural area were exposures.•It affected the patients' physical health, fitness, weight control regime and psychological wellbeing.•Lifestyle interventions are crucial but should target daily incremental changes tailored to patients' health needs, nutritional status, and socio-demographic and economic situation.
Individual food consumption surveys (IFCS) are performed to evaluate compliance with food/nutrient intake requirements or exposure to potential harmful dietary contaminants/components. In this ...review, we inventoried methods and designs used in national IFCS and discussed the methodologies applied across countries. Literature searches were performed using fixed sets of search terms in different online databases. We identified IFCS in thirty-nine countries from six world continents. National IFCS systems are available in most of the high-income countries, while such surveys are scarce in low- and middle-income countries (e.g. Africa, Eastern Europe and several Asian countries). Few countries (n 9) have their national IFCS incorporated into national health and nutrition surveys, allowing the investigation of dietary-related disease outcomes. Of the integrated surveys, most have the advantage of being continuous/regular, contrary to other IFCS that are mostly erratic. This review serves as the basis to define gaps and needs in IFCS worldwide and assists in defining priorities for resource allocation. In addition, it can serve as a source of inspiration for countries that do not have an IFCS system in place yet and advocate for national IFCS to be incorporated into national health and nutrition surveys in order to create: (1) research opportunities for investigating diet-disease relationships and (2) a frame to plan and evaluate the effect of diet-related policies (e.g. promotion of local nutrient-rich foods) and of nutrition recommendations, such as food-based dietary guidelines. Countries that integrate their IFCS within their national health and nutrition survey can serve as proof-of-principle for other countries.
► Primary experimental evaluation of essential elements in ready to feed infant foods. ► Evidence of a lack of attention to micro-nutrient interactions in food. ► Evidence of an inadequate intake of ...elements from an example menu with reference to the RNI. ► Scope and opportunities for new infant food product development.
There is a paucity of data in respect of the nutritional quality of complementary foods for infants and young children aged between 6 and 12months. The primary objective of this study was to examine nutritive values of such complementary infant food on the UK market in order to ascertain their suitability relative to dietary guidelines for the 6–9months age group. Quantitative analyses were conducted on eight different products representing four popular brands (meat and vegetable based) currently on sale in the UK. Eight major mineral and trace elements, namely: calcium, copper, magnesium, iron, zinc, potassium, sodium and selenium were measured by ICP–OES and ICP–MS. The results of these studies were referenced to the Recommended Nutrient Intake (RNI) values for 6–9months old children, and a menu of entire daily intake of minerals and trace elements was composed taking into consideration the nutrient and energy intake from milk consumption. Based on these comparisons, all the food samples studied in this work contained less essential minerals than expected from the RNI values except for potassium in meat and vegetable based recipes. These results suggest that commercial complementary infant foods on the UK market may not contain the minimum levels of minerals required for the labelling declaration of micronutrient content (Commission Directive 2006/125/EC). This provides opportunities and scope for product optimisation to improve their nutritive value.
Improved formulations of complementary foods (CFs) with animal-source foods (ASFs) is an important strategy to improve infant and young child feeding (IYCF). However, ASFs are expensive in many ...food-insecure settings where edible insects abound. CFs were developed from flours of orange-fleshed sweet potato (OFSP) and cricket (OFSCri) or palm weevil larvae (OFSPal) or soybean (OFSSoy) in the ratio 7:3. Nutritional and microbial quality of the novel CFs were determined and compared with Weanimix (recommended maize-peanut-soybean blend). Sensory evaluation of porridges was rated on a five-point hedonic scale among 170 Ghanaian mothers. OFSCri (20.33 ± 0.58 g/100 g) and Weanimix (16.08 ± 0.13 g/100 g) met the protein requirement of 15 g/100 g from CFs. Although Fe content was significantly higher for OFSCri (1.17 ± 0.03 mg/100 g), none of the CFs met the recommended levels for Fe. All the CFs were free from Salmonella, and aerobic plate count was significantly below permissible levels. All the CFs were ranked above the minimum threshold (hedonic scale = 3; neither like nor dislike) of likeness for the sensory attributes. Crickets and palm weevil larvae can be blended with OFSP and could be sustainable, culturally appropriate alternative ASFs for IYCF, but long-term studies are needed to evaluate their efficacy.
