RESUMO
BACKGROUND: Home gardens worldwide provide sustenance, economic support, and access to fresh produce and promote household well-being, health, self-sufficiency, and food security. However, they face significant challenges worldwide and necessitate innovative promotion approaches. Serious video games have proven effective in promoting agricultural knowledge. However, more research is needed on the persuasive potential of agriculture games to influence players' thoughts, attitudes, and behaviors. This provides an opportunity to examine the impact of persuasive games on promoting home gardening among novices. OBJECTIVE: This study aims to describe the design and development of Farmily, a persuasive video game promoting home gardening among novices. In addition, it evaluated the effectiveness of Farmily and compared its impact with that of a traditional home gardening workshop. Furthermore, the study explored how game enjoyment relates to the game's outcomes. METHODS: A randomized controlled trial with 50 novice gardening participants aged 20 to 50 years was carried out. Participants were randomly assigned to a control group (1.5-hour workshop) or an experimental group (1.5-hour Farmily session). Pre- and postintervention assessments were conducted. We evaluated Farmily's impact on knowledge, attitudes, perceived self-efficacy, and intentions regarding initiating home gardens. In addition, we investigated the user enjoyment and its relationship with the game's effect outcomes. RESULTS: The experimental group significantly improved their knowledge (t24=4.26; P<.001), attitude (z24=2.98; P=.003), self-efficacy (t24=2.6; P=.02), and intention to initiate home gardens (z24=4.15; P<.001). The experimental group showed similar effectiveness in knowledge transfer (t24=-1.71; P=.09) and a more significant impact on attitude (z24=2.73; P=.006), self-efficacy (t24=2.21; P=.03), and intention to start a home garden (t24=-5.33; P<.001) than the control group. Farmily was well received by the intervention group, generating high enjoyment. Furthermore, user enjoyment substantially correlated with user attitudes (r23=0.72; P<.001) and self-efficacy (r23=0.67; P<.001), yet no discernible association was observed among user enjoyment, knowledge (r23=0.26; P=.20), and intention (r23=0.06; P=.77). CONCLUSIONS: Evidence indicates that Farmily appears to be a viable tool for promoting home gardening among novices in the short term. Farmily demonstrated similar effects in knowledge improvement to those of a traditional workshop and had a more significant impact on the other variables. In addition, we found that the player's gaming experience positively relates to the player's attitudes and self-efficacy. A well-powered randomized controlled trial with more diverse samples and extended follow-up periods will be conducted to establish the long-term efficacy of Farmily and gain a deeper understanding of the influence of enjoyment on game outcomes.
RESUMO
Mexico is going through an environmental and nutritional crisis related to unsustainable dietary behaviours. Sustainable diets could solve both problems together. This study protocol aims to develop a three-stage, 15-week mHealth randomised controlled trial of a sustainable-psycho-nutritional intervention programme to promote Mexican population adherence to a sustainable diet and to evaluate its effects on health and environmental outcomes. In stage 1, the programme will be designed using the sustainable diets, behaviour change wheel and capability, opportunity, motivation, and behaviour (COM-B) models. A sustainable food guide, recipes, meal plans and a mobile application will be developed. In stage 2, the intervention will be implemented for 7 weeks, and a 7-week follow-up period in a young Mexican adults (18-35 years) sample, randomly divided (1:1 ratio) into a control group (n 50) and an experimental group (n 50), will be divided into two arms at week 8. Outcomes will include health, nutrition, environment, behaviour and nutritional-sustainable knowledge. Additionally, socio-economics and culture will be considered. Thirteen behavioural objectives will be included using successive approaches in online workshops twice a week. The population will be monitored using the mobile application consisting of behavioural change techniques. In stage 3, the effects of the intervention will be assessed using mixed-effects models on dietary intake and quality, nutritional status, physical activity, metabolic biomarkers (serum glucose and lipid profile), gut microbiota composition and dietary water and carbon footprints of the evaluated population. Improvements in health outcomes and a decrease in dietary water and carbon footprints are expected.

PURPOSE: Nutrition transition (NT) has modified the way that the Mexican population eats, while their body composition has also been modified. These changes have been linked with environmental impacts; however, little is known regarding water footprint (WF). The objective of this paper was to analyze the NT process in Mexico and evaluate its impact on WF using principal component analysis (PCA). METHODS: A validated Food Consumption Frequency Questionnaire (FCFQ) was modified and applied to 400 adults from the Metropolitan Zone of Guadalajara, Mexico. The WF was calculated according to the WF Assessment Method. PCA and tertiles analysis was carried out to define dietary patterns WFs (DPWF). Questions covering sociodemographic and socioeconomic factors, as well as body composition data and physical activity levels were measured. RESULTS: The average DPWF was 6619.58 ± 3182.62 L per person per day (L p-1d-1). We found three DPWF by PCA: Medium NT (55% from the total sample), Healthy plant-based (28%), and High in animal protein (17%). The highest energy consumption, western and Mexican foods intake, and dietary WF were found in Medium NT DPWF, as well as obesity prevalence. Fruits and vegetable consumption was higher in Healthy plant-based DPWF. Muscle mass percentage was higher in the High in animal protein DPWF. CONCLUSIONS: Although most of the population is currently on Medium NT, new dietary patterns have emerged, where there was found a trend to plant-based diets but also diets high in animal food sources that can influence nutritional status.

Water scarcity and excess adiposity are two of the main problems worldwide and in Mexico, which is the most obese country in the world and suffers from water scarcity. Food production represents 90% of a person's water footprint (WF), and healthy diets can lead to less WF than do unhealthy diets related to obesity. We calculated the WF of the diet and caloric intake of adults in Mexico and analyzed its relationship with adiposity. Also, the risk of water expenditure due to adiposity and adherence to dietary recommendations regarding WF of international healthy diets were examined. A Food Consumption Frequency Questionnaire (FCFQ) was applied to 395 adults. Body mass index (BMI), associated with adiposity indicators, was used as a reference for grouping a sample into adiposity levels. The WF was calculated according to the WF Assessment Method, considering correction factors and accounting for water involved in cooking and food washing. Our results showed that the Mexican diet spends 6,056 liters per person per day (L p-1d-1) and is 55% higher than international healthy diets WF. Consumption of beef, milk, fruits, chicken, and fatty cereals represented 56% of total WF. Strong relations appeared between hypercaloric diets and high WF. Diets of people with excess adiposity generated statistically higher WF with extra expenses of 729 L p-1d-1 compared with the normal adiposity population. Following nutritional recommendations offers a protective factor in water care, whereas not adhering to these represents a risk up to 93 times greater of water expenditure regarding international healthy diets. Therefore, both for the general population and to regulate obesity, adequate diets can help mitigate the problem of water scarcity.
RESUMO
Resumen En Zapotlán el Grande (ZEG) la producción de berries ha aumentado drásticamente, mientras que la de cultivos tradicionales ha disminuido. La disponibilidad de estos nuevos alimentos puede generar cambios en los hábitos alimentarios (HA) de la población. El objetivo del presente estudio fue evaluar la frecuencia y la cantidad de consumo de berries en población adulta de Ciudad Guzmán (ZEG, Jalisco, México), e identificar si estos han pasado a formar parte de sus HA. Participaron 384 adultos, de 18 a 65 años, residentes de Ciudad Guzmán, quienes fueron encuestados por medio de una versión adaptada de un cuestionario de frecuencia de consumo de alimentos. El 34% de los participantes refirió nunca consumir arándanos, frambuesas o zarzamoras, mientras que 39% los ingería ocasionalmente. En promedio, ninguno de los berries fue consumido en la ración propuesta en el Sistema Mexicano de Alimentos Equivalentes (SMAE), y solo representó 18% de la ración sugerida por la Organización Mundial de la Salud (OMS). Se concluye que aunque en cantidad inferior a la recomendada por la OMS o el SMAE, una cuarta parte de la población evaluada ha incorporado los berries a su dieta habitual, lo que demuestra que su disponibilidad está generando una modificación en los HA de la población.
Abstract In Zapotlán el Grande (ZEG) the production of berries has increased drastically, while traditional crops has decreased. The availability of these new foods may change eating habits (EH) of the population. The objective of this study was to assess the frequency and amount of berry consumption in the adult population of Ciudad Guzmán (ZEG, Jalisco, Mexico), and to identify if these have become part of their EH. A total of 384 adults, from 18 to 65 years old, residents of Ciudad Guzmán, were surveyed with an adapted version of a food consumption frequency questionnaire. The 34% of participants reported never consuming blueberries, raspberries or blackberries, while 39% eat them occasionally. On average, none of the berries was consumed in the amount proposed by the Mexican System of Equivalent Foods (SMAE), and only accounted 18% of the ration suggested by the World Health Organization (WHO). It is concluded that although the amount of berries consumed is less than the recommended by the WHO or SMAE, a quarter of the population assessed has incorporated berries into their usual diet, which shows that their availability is generating a change in the EH of the population.
