RESUMEN

OBJECTIVE: To examine the association between consumption of western foods purchased and consumed away from home and measures of nutrition quality: average daily caloric intake and macronutrient (carbohydrates, fat and protein) shares, for urban consumers in Vietnam, a country undergoing economic transition. DESIGN: Cross-sectional observational data were collected using household surveys and 24-h food diaries. Outcome variables were individual average daily caloric intake and shares of calories from macronutrients: carbohydrates, fat and protein. The key explanatory variable was individual daily share of calories from western food purchased and consumed away from home. Ordinary least squares and multivariate regression analyses were used to examine the association between the outcome variables: caloric intake and macronutrient shares and the share of calories from western food consumed away from home. SETTING: Hanoi and Ho Chi Minh City in Vietnam. PARTICIPANTS: In total, 1685 households and 4997 individuals, including adults (aged $$ \ge $$ 18 years), adolescents (aged 10-17 years) and children (aged 0-9 years). RESULTS: The share of calories from western food away from home was significantly associated with higher caloric intake among male and female adults (P < 0·01), adolescents (P < 0·01) and male children (P < 0·10) and was associated with higher shares of fat for male and female adults (P < 0·01), adolescents (P < 0·01) and male children (P < 0·01). CONCLUSIONS: Policymakers must be conscious of the numerous factors associated with poor nutrition quality, especially in younger Vietnamese individuals. Relevant interventions targeting at risk groups are required if nutrition improvement is a long-term goal.

RESUMEN

There is a growing trend of consumers in developed countries substituting alternative protein sources for meat and purchasing meat products with specific production-system related credence attributes. This study of Australian meat consumers identifies consumer segments with varying levels of willingness to make the following changes to their protein consumption: reduce meat consumption, follow a meat-free diet most of the time, avoid meat consumption altogether, and follow a strict plant-based diet (i.e., stop eating all animal-products). Segments are characterised, and predictors of segment membership are determined. Discrete Factor analysis, based on a nationally-representative sample of 287 Australian meat consumers surveyed in 2016, identified four unique segments. Findings show that 46% of consumers are not willing to make any changes to their meat/protein consumption ('Committed Meat Eaters'), 22% are willing to reduce meat consumption ('Willing Meat Reducers'), 15% are willing to stop meat consumption/consume plant-based protein foods only ('Prospective Veg*ns'), and 17% are undecided about future change ('Undecided Meat Eaters'). The key factor differentiating Committed Meat Eaters from other segments is the perception that food choices are inadequate in meat-free diets. Committed Meat Eaters are also less likely to believe livestock farming contributes to climate change, and to report a recent reduction in the consumption of at least one type of meat than are Willing Meat Reducers and Prospective Veg*ns. These findings are expected to be of interest to individuals and organisations who may play a role in meeting current and future consumer demand for meat and alternative protein products.

RESUMEN

We examined intrahousehold decision making with respect to household investment in portfolios of future rice varietal trait improvements (VTIs) to increase farm households' livelihoods in Nueva Ecija, Philippines. Investment decisions were elicited using an experimental methodology based on investment games. In the investment game, couples from rice farming households were given the opportunity to invest in public rice breeding. They selected, first individually, and then jointly, a replacement rice variety to improve upon and were then asked to allocate a research endowment fund to a portfolio of VTIs. We developed a novel indicator of women's intrahousehold decision-making power (WIDMP) based on the relative Euclidean distances between the individual and joint VTI portfolios. We found that WIDMP is normally distributed; and that, on average, women had almost equal (48%) decision-making power as men (52%), revealing almost perfect gender equity in investment decision making in rice breeding. Women were slightly more empowered if they were engaged in off-farm employment and were less experienced in farming. More empowered women had a higher discount factor and based their investment decisions on anticipated future trends, rather than current or past experience. The findings not only highlight the importance of considering gender roles in technology design, adoption and extension programs, but also have broader implications in terms of women empowerment programs. Consistent with the Sustainable Development Goals (SDGs), our evidence suggests that education and training programs need to be paired with investments generating off-farm employment opportunities to effectively increase women's bargaining power in the household.

RESUMEN

This study aims to aid in the development of more effective healthy eating intervention strategies for pregnant women by understanding the relationship between healthy eating intention and actual eating behaviour. Specifically, the study explored whether Theory of Planned Behaviour (TPB) constructs [attitude, subjective-norm, perceived-behavioural-control (PBC)] and additional psychosocial variables (perceived stress, health value and self-identity as a healthy eater) are useful in explaining variance in women's 1) intentions to consume a healthy diet during pregnancy and 2) food consumption behaviour (e.g. adherence to food group recommendations) during pregnancy. A cross-sectional sample of 455 Australian pregnant women completed a TPB questionnaire as part of a larger comprehensive web-based nutrition questionnaire. Women's perceived stress, health value and self-identity as a healthy eater were also measured. Dietary intake was assessed using six-items based on the 2013 Australian Dietary Guidelines. Hierarchical multiple linear regression models were estimated (significance level <0.05), which explained 70% of the variance in healthy eating intention scores and 12% of the variance in adherence to food group recommendations. TPB constructs explained 66% of the total variance in healthy eating intention. Significant predictors of stronger healthy eating intention were greater PBC and subjective norm, followed by positive attitude and stronger self-identity as a healthy eater. Conversely, TPB constructs collectively explained only 3.4% of total variance in adherence to food group recommendations. These findings reveal that the TPB framework explains considerable variance in healthy eating intention during pregnancy, but explains little variance in actual food consumption behaviour. Further research is required to understand this weak relationship between healthy eating intention and behaviour during pregnancy. Alternative behavioural frameworks, particularly those that account for the automatic nature of most dietary choices, should also be considered.

RESUMEN

To help meet the increased requirements for critical nutrients during and around pregnancy, supplementation with essential nutrients is recommended. This study aims to determine how the previous awareness of nutrient health benefits and/or the provision of this information influences the importance placed on nutrients (folate, iodine, omega-3 fatty acids, and vitamin D) when choosing between dietary supplement products for pregnancy. Discrete choice experiment data were collected as part of a cross-sectional online survey administered to 857 pregnant women living in Australia. Four segments of women were identified that differ in their preference criteria when choosing among dietary supplement products for pregnancy. When choosing between products, the reinforcement of perceived health benefits (i.e., showing information on health benefits to those already aware of the benefits) was most effective at increasing the importance of folate (in all segments) and iodine (in two segments, 63% of the sample). Neither prior awareness of health benefits alone nor information provided at the point-of-purchase without prior awareness were enough to increase the importance of folate. Our findings suggest a need for simultaneous strategies that (1) provide information on health benefits before purchase and (2) ensure that information on health benefits is available at the point-of-purchase.

RESUMEN

Using an experimental methodology based on investment games, we examine whether smallholder rice farmers from Nueva Ecija, Philippines have heterogeneous preferences for improvements in 10 rice varietal traits. We use a latent class cluster approach to identify different segments of rice producing households and their distinct preferences for trait improvements. These clusters were characterised post hoc using household, farm, and marketing characteristics. On average, farmers invested the most in rice varietal trait improvements that offered opportunities to reduce losses caused by lodging, insects and diseases. We found four classes of farmers with distinct preferences for improvements in variety traits. The clusters were significantly different in terms of household and farm characteristics. These findings can guide breeding research in the development of varieties that have the traits farmers identified for improvement, and that will address the unique needs of distinct farmer segments.

RESUMEN

Vietnam is experiencing a diet and nutrition transition. Increasing consumption of food and beverages with added sugars is a significant public health concern. Policies and interventions, such as mandatory nutrition labelling, are being considered to improve consumers' awareness and understanding of diet and health implications of added sugars in food and beverages. The effectiveness of various policy approaches relies on an improved understanding of the interrelationships between urban Vietnamese consumers' health concerns, nutrition label use, and intake of sugars. We empirically disentangle these relationships for urban Vietnamese households using novel intra-household data covering 4047 adults and 737 adolescents from 1590 households in Hanoi and Ho Chi Minh City. The data are from comprehensive household surveys and 24-hour food diaries. Simultaneous equation regression models are estimated using three-stage least squares (3SLS) to account for possible endogeneity. Nutrition label use is significantly associated with a lower share of calories from foods and beverages with added sugars. These findings suggest that nutrition labelling programs may be an effective policy mechanism to reduce the negative health implications of increasing availability and consumption of food and beverages with added sugars in urban Vietnam.

RESUMEN

Cow-calf production occurs in all 50 states over varied resource bases and under vastly different environmental conditions. Multiple breeds exist and management styles and objectives are as numerous as the number of cow-calf producers. There is not one area of the country, one breed of cattle, or one management style that is most profitable for producing cows and calves. There are, however, some common strategies that can be employed by cow-calf producers to enhance profitability. Costs need to be controlled without jeopardizing cow herd productivity or net returns. It appears that the cost associated with purchased and harvested feeds varies considerably across operations. Understanding cyclic and seasonal price patterns, weight-price slides, cattle shrink, and other marketing costs can help producers enhance their profit by marketing (and not by just selling) their cattle. Producers with superior cattle genetics can become part of a specific alliance or, at a minimum, document the performance of their cattle so that they can get paid for the superior genetics. The beef industry is changing and will likely continue to change. Cow-calf producers will need to examine their own management practices to determine whether they are optimal for the current industry. Those producers who are most adept at matching their management abilities to their cattle type, their resource base, and the appropriate market outlet will be the most successful in the future.
