Meat, Masculinity, and Health for the "Typical Aussie Bloke": A Social Constructivist Analysis of Class, Gender, and Consumption.

Food choice is complex and influenced by a range of social, environmental, structural, and individual factors. Poor diet is one of the major contributors to the burden of disease, in particular for men who habitually have lower intakes of fruits and vegetables and higher intakes of meat. Food choice has been linked to the expression of masculine identities. This research used a Bourdieusian framework to explore the influential drivers of young Australian men's eating habits based on occupational groupings. Twenty men aged 19-30 years participated in in-depth semistructured interviews. Analysis used a grounded theory, social constructivist approach and identified five themes: performative masculinities and meat; meat cuts across social class; the influence of masculine autonomy on dietary choice; women protecting Australian men's health; and the role of environmental and structural barriers. These results indicated that habitus remains a useful conceptual framework to explain the results, and cultural capital is reinforced as a phenomenon. Occupation and gender appear to no longer be primary drivers of food choice in this group of men. Rather there is a shift toward an understanding of multiple masculinities and the development of microcultures with interactions between structure and agency. Meat still features in the food world of Australian men, but there are shifts to deprioritize its importance. There needs to be a more nuanced understanding of the importance of autonomy and control as well as the role of women in relation to men's dietary intakes and how this can be harnessed for positive dietary change.

A Bayesian approach for analysis of ordered categorical responses subject to misclassification.

Ordinal categorical responses are frequently collected in survey studies, human medicine, and animal and plant improvement programs, just to mention a few. Errors in this type of data are neither rare nor easy to detect. These errors tend to bias the inference, reduce the statistical power and ultimately the efficiency of the decision-making process. Contrarily to the binary situation where misclassification occurs between two response classes, noise in ordinal categorical data is more complex due to the increased number of categories, diversity and asymmetry of errors. Although several approaches have been presented for dealing with misclassification in binary data, only limited practical methods have been proposed to analyze noisy categorical responses. A latent variable model implemented within a Bayesian framework was proposed to analyze ordinal categorical data subject to misclassification using simulated and real datasets. The simulated scenario consisted of a discrete response with three categories and a symmetric error rate of 5% between any two classes. The real data consisted of calving ease records of beef cows. Using real and simulated data, ignoring misclassification resulted in substantial bias in the estimation of genetic parameters and reduction of the accuracy of predicted breeding values. Using our proposed approach, a significant reduction in bias and increase in accuracy ranging from 11% to 17% was observed. Furthermore, most of the misclassified observations (in the simulated data) were identified with a substantially higher probability. Similar results were observed for a scenario with asymmetric misclassification. While the extension to traits with more categories between adjacent classes is straightforward, it could be computationally costly. For traits with high heritability, the performance of the methodology would be expected to improve.

Interventions targeting conscious determinants of human behaviour to reduce the demand for meat: a systematic review with qualitative comparative analysis.

BACKGROUND: Reducing meat consumption can help prevent non-communicable diseases and protect the environment. Interventions targeting conscious determinants of human behaviour are generally acceptable approaches to promote dietary change, but little is known about their effectiveness to reduce the demand for meat. OBJECTIVE: To evaluate the effectiveness of interventions targeting conscious determinants of human behaviour to reduce the demand for meat. METHODS: We searched six electronic databases on the 31st of August 2017 with a predefined algorithm, screened publicly accessible resources, contacted authors, and conducted forward and backward reference searches. Eligible studies employed experimental designs to evaluate interventions targeting conscious determinants of human behaviour to reduce the consumption, purchase, or selection of meat in comparison to a control condition, a baseline period, or relative to other eligible interventions. We synthesised results narratively and conducted an exploratory crisp-set Qualitative Comparative Analysis to identify combinations of intervention characteristics associated with significant reductions in the demand for meat. RESULTS: We included 24 papers reporting on 59 interventions and 25,477 observations. Self-monitoring interventions and individual lifestyle counselling led to, or were associated with reduced meat consumption. Providing information about the health or environmental consequences of eating meat was associated with reduced intentions to consume and select meat in virtual environments, but there was no evidence to suggest this approach influenced actual behaviour. Education about the animal welfare consequences of eating meat was associated with reduced intentions to consume meat, while interventions implicitly highlighting animal suffering were not. Education on multiple consequences of eating meat led to mixed results. Tailored education was not found to reduce actual or intended meat consumption, though few studies assessed this approach. CONCLUSION: Some interventions targeting conscious determinants of human behaviour have the potential to reduce the demand for meat. In particular, self-monitoring interventions and individual lifestyle counselling can help to reduce meat consumption. There was evidence of effectiveness of some educational messages in reducing intended consumption and selection of meat in virtual environments. PROTOCOL REGISTRATION: CRD42017076720 .

Comportamento econômico social do consumidor de carne bovina do município de Guanhães, MG / Social economic behavior of beef consumers in the municipality of Guanhaes, MG

Com o advento do mundo moderno e a globalização, o comportamento do consumidor em relação ao seu processo decisório de compra mudou drasticamente. A crescente preocupação com o consumo de produtos cárneos tem impelido à busca da qualidade e o desenvolvimento de técnicas de manejo e produção que amenizem o sofrimento dos animais, como um diferencial competitivo. Este artigo objetivou, identificar e caracterizar o perfil do consumidor de carne e derivados, ressaltando seus hábitos alimentares frente ao produto e também seu perfil socioeconômico e identificar o grau de importância atribuída às informações disponibilizadas no momento da compra. A partir de um questionário aplicado a uma amostra de 66 consumidores da cidade de Guanhães, Minas Gerais, os resultados sugerem que os consumidores apresentam interesse por informações ainda não disponibilizadas pelos fornecedores e que os produtos cárneos oferecidos no mercado não dispõem de informações suficientes para que o consumidor possa estar totalmente ciente do tipo de produto que está levando para casa e dos riscos envolvidos na aquisição de produtos de origem de abate clandestino.

[Dietary habits and social differences: the experience of EPIC-Italy]. / Abitudini alimentari e disuguaglianze sociali: l'esperienza della collaborazione EPIC-Italia.

OBJECTIVES: to investigate the impact of socioeconomic status on dietary habits in Italy. DESIGN: large Italian multicentric prospective cohort study. SETTING AND PARTICIPANTS: more than 45,000 subjects recruited between 1993 and 1998 in five Italian centres (Turin, Varese, Florence, Naples, and Ragusa). Dietary habits, educational level, and other characteristics were collected at baseline using standardised questionnaires. MAIN OUTCOME MEASURES: dietary habits collected for the EPIC study, grouped by food type and summarised by a Mediterranean dietary index. RESULTS: we observed differences in dietary habits and in lifestyle habits by tertile of educational level. Principally, we noticed a positive association between higher education and healthy dietary habits (reduction in intake of processed meat, bread and rice, sweet drinks; increase in intake of fruit and vegetables, yoghurt, fish, olive oil, and tea). CONCLUSION: a relationship between educational level and dietary habits is confirmed also in Italy, even if differences due to gender and residence area are present. This study shows an important role of dietary habits in health inequalities of the population with lower socioeconomic status.

[Health inequalities and nutrition in Italy during crisis times]. / Disuguali a tavola, ma non troppo: le differenze sociali nell'alimentazione in Italia prima e durante la crisi.

OBJECTIVES: to describe systematically unhealthy patterns in nutrition behaviours, with a special focus on the impact of social, gender, geographical, and age inequalities on diet; to evaluate the potential impact of economic crisis on healthy nutrition choices and on health inequalities. DESIGN: cross sectional study within national surveys. SETTING AND PARTICIPANTS: population ≥20 years, from representative samples of the Italian population in official national multipurpose surveys, in the periods 2005-2007 and 2009-2012. MAIN OUTCOME MEASURES: prevalence, population attributable fraction (PAF), and relative time variation between periods. RESULTS: wide differences on the prevalence of nutrition healthy behaviour have been found according to social position (low educated have higher consumption of meat, carbohydrates, salty food, higher breakfast skipping rates as well as lower consumption of fish), geographical area (Northern regions have higher consumption of meat, carbohydrates and fats, whereas Southern ones have lower consumption of fruit and vegetables, higher obesity, and overweight rates). Economic crises seems to have had an impact on nutrition (reduction of meat, fruit and vegetable consumption, increase on snack and legumes frequencies, less fish, and meat presence on diet), but lower than expected. Besides, if long period trends seem to increase health inequalities on nutrition, crisis seems to have had an opposite effect. CONCLUSION: unhealthy patterns seem to be present in Italian food behaviour and long time trends appear to increase them, as illustrated by the spread of obesity and overweight. Nevertheless, Mediterranean diet does not seem to be too much at risk. Economic crisis has been frequently recognized as a determinant of nutrition patterns worsening, but it has had different impacts. Furthermore, health inequalities could be decreased in crisis times.

Spatiotemporal trends of illegal activities from ranger-collected data in a Ugandan national park.

Within protected areas, biodiversity loss is often a consequence of illegal resource use. Understanding the patterns and extent of illegal activities is therefore essential for effective law enforcement and prevention of biodiversity declines. We used extensive data, commonly collected by ranger patrols in many protected areas, and Bayesian hierarchical models to identify drivers, trends, and distribution of multiple illegal activities within the Queen Elizabeth Conservation Area (QECA), Uganda. Encroachment (e.g., by pastoralists with cattle) and poaching of noncommercial animals (e.g., snaring bushmeat) were the most prevalent illegal activities within the QECA. Illegal activities occurred in different areas of the QECA. Poaching of noncommercial animals was most widely distributed within the national park. Overall, ecological covariates, although significant, were not useful predictors for occurrence of illegal activities. Instead, the location of illegal activities in previous years was more important. There were significant increases in encroachment and noncommercial plant harvesting (nontimber products) during the study period (1999-2012). We also found significant spatiotemporal variation in the occurrence of all activities. Our results show the need to explicitly model ranger patrol effort to reduce biases from existing uncorrected or capture per unit effort analyses. Prioritization of ranger patrol strategies is needed to target illegal activities; these strategies are determined by protected area managers, and therefore changes at a site-level can be implemented quickly. These strategies should also be informed by the location of past occurrences of illegal activity: the most useful predictor of future events. However, because spatial and temporal changes in illegal activities occurred, regular patrols throughout the protected area, even in areas of low occurrence, are also required.

Perdas econômicas ocasionadas por lesões em carcaças de bovinos abatidos em matadouro-frigorífico do norte de Mato Grosso / Economic losses caused by injuries in carcasses of cattle slaughtered in northern Mato Grosso, Brazil

Este estudo teve o objetivo de avaliar as perdas econômicas decorrentes de lesões de transporte e manejo pré-abate em carcaças de bovinos abatidos em matadouro-frigorífico inspecionado na região norte do Estado de Mato Grosso/MT, Brasil. De um total de 1.021 animais avaliados identificou-se que 433(42,4%) apresentavam carcaças com lesões relacionadas ao transporte e manejo pré-abate. A frequência de lesões encontradas evidenciou uma diferença (P<0,05)de acordo com o tempo de transporte, em que, com o transporte de até duas horas foi observado 1,82 lesão/carcaça lesionada e 2,05 lesão/carcaça lesionada com o tempo de 2 a 8 horas, sendo que para tempo de transporte maior que 8 horas, foi observado 2,07 lesões/carcaça lesionada, sendo esse valor igual (P>0,05)aos valores encontrados para transporte entre 2 a 8 horas.Os animais lesionados apresentaram de uma até seis lesões em sua carcaça, com uma maioria (96,9%) variando entre 1 a 4 lesões, sendo que os animais transportados por mais de 2 horas apresentaram mais lesões que os animais transportados por até 2 horas (P<0,05).Foi observado que o local de maior incidência de lesões foi o lombo, com 50,35% das lesões, seguido pela região do coxão com 36,38% das lesões encontradas neste estudo.

This study evaluates the economic losses caused by lesions during shipping and pre-management in cattle slaughtered in Mato Grosso, Brazil. From 1,021 carcasses evaluated, 433 (42.4%) presented injuries caused hrough transportation and pre-slaughter management. Lesion frequency varied significantly with shipping times (P<0.05). Animals transported for up to 2 hours presented 1,82 lesion/carcass. In turn, animals transported 2 to 8 hours exhibited 2.05 lesion/carcass, what however did not differ statistically from the number of lesions in animals transported for more than 8 hours (2.07 lesion/carcass; P>0.05). Injured animals presented up to six lesions, although most (96.9%) had up to four lesions. Cattle transported for more than 2 hours presented more lesions than animals shipped for less than 2 hours (P<0.05). Most lesions were obsetrved on the loin (50.35% of lesions), followed by the rump (36.38%). Total weight loss of animals accounted for 115.76 kg, Annual economic losses in a midsized slaughterhouse were estimated at R$ 200,000 by lesions caused during transport and pre-slaughter management of cattle...

Age at menarche and diet among adolescents in slums of Nashik, India.

BACKGROUND AND AIM: The role of dietary patterns in determining age at menarche is insufficiently understood in low-income countries. The relationship between dietary patterns, particularly the consumption of oil, and age at menarche in a slum-dwelling adolescent population in India is examined. METHODS: Data were derived from a cross-sectional baseline survey and anthropometric measurements among 10- to 19-year-old adolescents (n=545, female respondents 272, of whom 160 were post-menarcheal) and a household survey in two slums in the city of Nashik, Western India. By using mixed effects linear regression models, the association between age at menarche and household-wise use of sources of animal protein and oil and fat is examined. RESULTS: Age at menarche (mean 13.7 years) in the slums studied was relatively high according to Indian standards. Age at menarche and the consumption of dairy products, meat, fish and eggs were not associated. The household per capita consumption of vegetable oil had an inverse association with a girl's age at menarche, and there was an indication of a positive association between use of ghee (clarified butter) and age at menarche. These associations did not disappear when controlling for anthropometric status and socio-economic characteristics. CONCLUSION: Intake of fats and foods that are important sources of protein among underprivileged households in India is low and reflected in the relatively late age at menarche. The potential differences in the association between various types of fatty acids, energy intake and age at menarche in conditions of undernutrition requires further prospective study.

The economic impact of H1N1 on Mexico's tourist and pork sectors.

By examining tourist arrivals and pork output and trade statistics, this analysis estimates the economic impact to the Mexican tourism and pork sectors because of the H1N1 influenza pandemic. It also assesses the role of the international response in the context of this economic impact. For tourism, losing almost a million overseas visitors translated into losses of around $US2.8bn, which extended over a five-month period, mostly because of the slow return of European travellers. For the pork industry, temporal decreases in output were observed in most of the country and related to H1N1 incidence (p = 0.048, r = 0.37). By the end of 2009, Mexico had a pork trade deficit of $US27m. The losses derived from this pandemic were clearly influenced by the risk perception created in tourist-supplying and pork trade partners. Results suggest that the wider economic implications of health-related emergencies can be significant and need to be considered in preparedness planning. For instance, more effective surveillance and data gathering would enable policy to target emergency funding to the sectors and regions hardest hit. These results also stress the importance of being familiar with trade networks so as to be able to anticipate the international response and respond accordingly.

Dietary intake and health risk assessment of lead and cadmium via consumption of cow meat for an urban population in Enugu State, Nigeria.

The study assessed the dietary intake of lead and cadmium and health risk from consumption of various parts of cow meat by the urban population of Enugu State, Nigeria. Meat samples (n=150) comprising of muscle, liver, kidney, intestine and tripe were purchased from abattoirs in Nsukka and Enugu. The samples were dried, ground and two gram was digested with 3:2 HNO3:HClO4 v/v. The Cd and Pb concentrations were read with an atomic absorption spectrophotometer. The dietary intakes were estimated using a one week food frequency questionnaire administered to 755 subjects. The dietary intake of lead (µg/kg body weight/week) were in the following ranges; men [0.15 (kidney)-0.55(intestine)], non pregnant/non lactating women [0.16 (kidney)-0.62 (liver)], pregnant/lactating women [0.13 (kidney)-0.53 (intestine)], undergraduate students [0.12 (kidney)-0.62 (intestine)] and school children [0.29 (kidney)-1.16 (liver)]; cadmium: men [0.42 (liver)-1.21 (tripe)], non-pregnant/non-lactating women [0.53 (kidney)-1.20 (tripe)], pregnant/lactating women [0.43 (kidney)-0.90 (intestine)], undergraduate students [0.40 (kidney)-1.18 (tripe)] and school children [0.97 (kidney)-1.93 (tripe)]. The total dietary intakes of lead from the various cow meat parts by the groups were much lower than the provisional tolerable weekly intake (PTWI) guide line, but for cadmium, the intakes were quite appreciable when compared to the PTWI guideline while the intake for school children was very high, 113% of PTWI for the metal. The target hazard quotients were in the range of 0.05-0.10 for lead and 0.42-0.90 for cadmium. These values are less than one, indicating that the subjects are not exposed to any significant health risk via cow meat consumption.

Food expenditures, cariogenic dietary practices and childhood dental caries in southern Brazil.

Family expenditures on food for children may represent an important barrier to the adoption of healthy feeding practices in populations of low socioeconomic status. The aim of this study was to explore the relationship between cariogenic feeding practices, expenditures on food for children and dental caries. This cross-sectional study included 329 four-year-old children from São Leopoldo in southern Brazil. Cariogenic dietary practices were assessed at 4 years of age using two 24-hour recalls conducted with the children's mothers. Expenditures on food for children were estimated based on all reported food items and the respective amounts ingested. Early childhood caries and severe early childhood caries were assessed by clinical examination at 4 years of age. Cariogenic dietary habits were not associated with lower food expenditures. On the contrary, in multivariable regression analysis, the intake of chocolate (p = 0.007), soft drinks (p = 0.027) and a higher number of meals and snacks per day (p < 0.001) was associated with greater expenditures on food for children. No statistically significant differences were observed in food expenditures or in the proportion of household income spent on feeding children between caries-free children, those with early childhood caries and those with severe early childhood caries. In conclusion, keeping children free of dental caries does not necessarily increase food expenditures or the proportion of household income spent on feeding children in low-socioeconomic status populations. Some cariogenic dietary practices were associated with greater expenditures on child feeding.

Excessive meat consumption in Brazil: diet quality and environmental impacts.

OBJECTIVE: To evaluate red and processed meat intake, and the impact meat consumption has on diet quality and the environment. DESIGN: A large cross-sectional health survey performed in São Paulo, Brazil. SETTING: Diet was assessed by two 24 h dietary recalls. Usual intakes were calculated using the Multiple Source Method. The World Cancer Research Fund recommendation of an average of 71.4 g/d was used as the cut-off point to estimate excessive red and processed meat consumption. To investigate the relationship between meat consumption and diet quality we used the Brazilian Healthy Eating Index Revised. The environmental impact was analysed according to estimates of CO2 equivalent emissions from meat consumption. SUBJECTS: Brazilians (n 1677) aged 19 years and older were studied. RESULTS: The mean red and processed meat intake was 138 g/d for men and 81 g/d for women. About 81% of men and 58% of women consumed more meat than recommended. Diet quality was inversely associated with excessive meat intake in men. In Brazil alone, greenhouse gas emissions from meat consumption, in 2003, were estimated at approximately 18,071,988 tonnes of CO2 equivalents, representing about 4% of the total CO2 emitted by agriculture. CONCLUSIONS: The excessive meat intake, associated with poorer diet quality observed, support initiatives and policies advising to reduce red and processed meat intake to within the recommended amounts, as part of a healthy and environmentally sustainable diet.

[Relashionship between the mother's educational level and child feeding in a series of preschool children in Bacau Town]. / Relatia între nivelul educational matern si alimentatie la un lot de prescolari din orasul Bacau.

UNLABELLED: Child growth and development are decisively influensed by feeding. This depends on parent's financial resources and food habits, most often tradition-related. AIM: To determine how important mother's educational level is in this respect. MATERIAL AND METHODS: The study was carried out on a series of 153 preschool children from two kindergartens in Bacau town. Their parents filled out a questionnaire on the frequency of weekly food consumption. RESULTS: 64.5% of the mothers of the children included in this study had a higher education. Most children had milk 4-7 times a week, cheese 2-3 times a week, eggs and chicken 2-3 times a week, and fruits 4-7 times a week. The diffrences in feeding provided by mothers with higher education and those less educated were statistically insignificant, food habits being quite similar. CONCLUSIONS: A good knowledge of food habits in a poplation is essential for developing programs aimed at changing the unhealthy ones.

Differential effects of negative publicity on beef consumption according to household characteristics in South Korea.

This paper examines how South Korean households responded to an unprecedented boycott campaign against US beef from spring to summer of 2008, and investigates differential responses in relation to households' characteristics. It was found that beef consumption reduced by 4.8% immediately after the so-called candle-light demonstration. Instead, pork and chicken consumption increased by 17.2% and 16.6%, respectively. This confirms a substitution effect due to the negative publicity concerning US beef. It was also found that the negative publicity effect was transitory and the reactions of consumers were not uniform; they differed depending on their socio-economic characteristics. The econometric model revealed that younger, less-educated, and/or lower-income households were more susceptible to the negative publicity, and reduced their beef consumption more than other households.

A quantitative microbial risk assessment for meatborne Toxoplasma gondii infection in The Netherlands.

Toxoplasma gondii is an important foodborne pathogen, and the cause of a high disease burden due to congenital toxoplasmosis in The Netherlands. The aim of this study was to quantify the relative contribution of sheep, beef and pork products to human T. gondii infections by Quantitative Microbial Risk Assessment (QMRA). Bradyzoite concentration and portion size data were used to estimate the bradyzoite number in infected unprocessed portions for human consumption. The reduction factors for salting, freezing and heating as estimated based on published experiments in mice, were subsequently used to estimate the bradyzoite number in processed portions. A dose-response relation for T. gondii infection in mice was used to estimate the human probability of infection due to consumption of these originally infected processed portions. By multiplying these probabilities with the prevalence of T. gondii per livestock species and the number of portions consumed per year, the number of infections per year was calculated for the susceptible Dutch population and the subpopulation of susceptible pregnant women. QMRA results predict high numbers of infections per year with beef as the most important source. Although many uncertainties were present in the data and the number of congenital infections predicted by the model was almost twenty times higher than the number estimated based on the incidence in newborns, the usefulness of the advice to thoroughly heat meat is confirmed by our results. Forty percent of all predicted infections is due to the consumption of unheated meat products, and sensitivity analysis indicates that heating temperature has the strongest influence on the predicted number of infections. The results also demonstrate that, even with a low prevalence of infection in cattle, consumption of beef remains an important source of infection. Developing this QMRA model has helped identify important gaps of knowledge and resulted in the following recommendations for future research: collect processing-effect data in line with consumer style processing and acquire product specific heating temperatures, investigate the presence and concentration of viable bradyzoites in cattle, determine the effect of mincing meat on bradyzoite concentrations using actual batch sizes, and obtain an estimate of the fraction of meat that has been frozen prior to purchase. With more accurate data this QMRA model will aid science-based decision-making on intervention strategies to reduce the disease burden from meatborne T. gondii infections in The Netherlands.

[Collaboration between general practitioners and the school: survey about student's dietary habits in the first classes of secondary school in the province of Carbonia-Iglesias, Sardinia]. / Collaborazione tra i medici di medicina generale e la scuola: indagine sulle abitudini alimentari degli studenti delle prime classi della scuola secondaria superiore nella provincia Carbonia-Iglesias della Sardegna (Italia).

WHO stresses the importance of promoting balance diet among adolescents. The general practitioners are called at the forefront in the prevention of disorders related to eating habits. The present study describes a project to promote nutrition, created and run by general practitioners in the first classes of 20 secondary schools in seven municipalities, in the province of Carbonia-Iglesias (Italy), for a sample of 509 students (220 females and 289 males). The results also offer an expanded view of the eating habits of adolescents. The results show that adolescents do not give importance to the breakfast that is often not complete or is not consumed, and only 50% of respondents drink milk. The highest percentage of students consuming the first and second course (45-59%) at lunch and dinner consumption of protein was high ranging between 64 and 80% for lunch and dinner at 63 and 66%. That is evidenced by these results can be a valuable aid for future health promotion interventions.
