RESUMEN

This study examined the cross-sectional relationship between caregivers' perceived competence and autonomy (as defined by the Self-Determination Theory) and their fast food or counter service restaurant food purchases (side dishes, beverage, and dessert) for their child. A U.S. national convenience sample of caregivers with at least one 3-12-year-old child completed an online survey with questions adapted from the Intrinsic Motivation Inventory that measured perceived competence and autonomy for feeding fruits and vegetables and limiting sugar-sweetened beverages (SSBs) and desserts. The survey included four questions asking about their fast food or counter service restaurant food purchases (side dish, beverage, and dessert). We applied logistic and multinomial logistic regression models to examine the associations between competence or autonomy and restaurant orders. Competence and autonomy were associated with ordering fruits and vegetables as side dishes (OR [95% CI], 1.14 [1.06, 1.24] and 1.09 [1.03, 1.14], respectively). However, higher competence was also associated with ordering desserts at restaurants and higher autonomy was associated with lower odds of ordering water. These findings will inform interventions and programs that aim to support caregivers' psychological needs, like competence and autonomy, to promote supportive environments and healthier restaurant purchases for their children.

RESUMEN

The COVID-19 pandemic has been stressful, potentially affecting caregivers' feeding choices. Caregivers play a role in shaping children's diets, yet few studies have explored how their competence and autonomy, defined by the Self-Determination Theory, impact children's diets. We examined the relationship between caregivers' autonomy and competence and their feeding practices before and during the first year of the pandemic. A national convenience sample of caregivers with 3-12-year-old children completed an online survey during two time-periods. Questions adapted from the Intrinsic Motivation Inventory measured perceived competence and autonomy for feeding fruits and vegetables (F/V) and limiting sugar-sweetened beverages (SSBs) and desserts. National Health and Nutrition Examination Survey Dietary Screener questions measured children's consumption of F/V, SSBs, and desserts. Paired t-tests examined how child consumption and caregiver's perceived competence and autonomy changed, and logistic regressions examined whether caregivers' competence and autonomy predicted the change in child consumption and if changes in competence and autonomy were associated with changes in child consumption. Caregivers (n = 597) were mostly Black/African American (33.0%) or Latina/o/x (42.7%) and older than 30 years (84.1%). Children's consumption did not change overall, but caregivers' competence for feeding F/V increased, and their competence for limiting SSBs and desserts decreased. Caregiver competence and autonomy before COVID-19 did not predict child dietary consumption during the pandemic. However, change in competence was a significant predictor of the change in child consumption of F/V [OR (95%CI): 0.70 (0.57, 0.86)]. The association between caregiver's perceived competence for feeding F/V and child consumption remained positive and significant in both periods [OR (95%CI) pre and during COVID: 2.09 (1.69, 2.57) - 2.40 (1.88, 3.06)]. This study can inform behavioral interventions supporting caregivers' competence and autonomy around feeding choices.

RESUMEN

There remains a lack of scientific consensus on what level of carbohydrate intake constitutes low-carbohydrate diets. We conducted a scoping review to understand how low-carbohydrate diets were defined in the peer-reviewed literature. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement scoping review extension. Three electronic databases were searched for clinical studies in English. We identified 508 articles (317 randomized controlled, 99 cross-over, 33 before-and-after, 12 non-randomized, and 47 other clinical trials). Most examined effects of low-carbohydrate diets in healthy adults (62.4%), 40 to 59 years old (55.5%), with obesity or overweight (66.1%). The majority reported effects on weight or body composition (29.9%), diabetes (18.7%), or cardiovascular risk factors (12.9%) as primary outcomes. Most articles (56.9%) reported percent of energy from carbohydrates, and of those, 60.3% defined low-carbohydrate diets as being ≤30% of energy from carbohydrates. Some articles (22.9%) reported grams of carbohydrates per day, and of those, most defined low-carbohydrate diets as being under ∼100 grams of carbohydrates per day. Systematic reviews and dose-response meta-regressions utilizing patient-level data on carbohydrate intake, status markers (e.g., RQ/ketones), and health outcomes would be useful in informing consensus around a standardized definition.

RESUMEN

A cluster of factors affects nutritional status among adolescent girls in low- and middle-income countries (LMICs). We investigated the association between school attendance and diet quality among 498 rural adolescent girls (352 attending and 146 not attending school) in Tecpán, Guatemala. In a cross-sectional study, we collected sociodemographic and anthropometric data and characterized the dietary intake using a Food Frequency Questionnaire. We then calculated diet quality using the Healthy Eating Score (HES). Multiple linear regression models were conducted to evaluate the effects of school attendance on diet quality. We found that the overall diet quality among the study participants was poor, according to the HES. However, those who attended school had significantly higher intakes of vitamin A-rich fruits and vegetables (P = 0.04), other fruits (P = 0.01), and milk and milk products (P = 0.004), but a higher intake of fast foods, chips, and saturated fatty acids (P < 0.001). Furthermore, the effects of school attendance on diet quality were significant after adjusting for sociodemographic and lifestyle factors (ß coefficient = -1.70, 95% CI: -3.30 to -0.11) but was attenuated when further adjusted for weight status (ß coefficient = -1.58, 95% CI: -3.17 to 0.02). Our findings suggest that diet quality among girls in rural Guatemala is poor, particularly among those who do not attend school. To advance our understanding of adolescent diet in LMICs, future studies should include adolescents who are out of school.

RESUMEN

In low- and middle-income countries, gender norms and access to energy-dense, nutrient-poor foods are well-studied determinants of food and physical activity choices for adolescent girls. However, most work has been done in urban and school settings. In many settings, a large proportion of the adolescent population is rural or not enrolled in school. We conducted in-depth interviews with 20 adolescent girls (ages 15-19) in Tecpán, Guatemala, a rural, largely indigenous Maya community. Interviews were coded and themes analyzed for insights into eating habits, food choices, and physical activity. Twelve participants were enrolled in school and eight were employed and not in school. Girls enrolled in school had more disrupted eating schedules and consumed more energy-dense, nutrient-poor foods. Girls not enrolled in school had fewer opportunities for physical activity and were more sedentary. To our knowledge, this study is the first in a low- and middle-income country to consider diet and physical activity of adolescent girls enrolled and not enrolled in school. Key implications include (1) the need to reduce exposure to nutrient-poor foods and promote healthy eating schedules in schools, and (2) the need to create community-based opportunities for the activity for girls no longer enrolled in school.

RESUMEN

BACKGROUND: The obesity epidemic is spreading rapidly in Guatemala, a low/middle income country still struggling with undernutrition. Sugar sweetened beverages (SSBs) consumption is strongly associated with overweight, obesity, and non-communicable diseases. In Guatemala, SSBs are readily available and consumption is high, particularly among adolescents. SSB taxes have been proposed as a cost-effective way to reduce consumption and generate revenues for public health, as has been demonstrated in several countries around the world. OBJECTIVE: To estimate the price, expenditure, quality, and cross-price elasticity of beverage demand using household survey data. METHOD: We conducted a secondary analysis on the 2014 Guatemala Living Conditions National Survey that includes national representative household data on expenditure. Own price, expenditure, quality, and cross-price elasticities of milk, soft drinks, packaged juices, and bottled water were estimated using Deaton's Almost Ideal Demand System (AIDS), controlling for goods' quality. Household characteristics and beverage expenditure are summarized for urban and rural locations using descriptive statistics. RESULTS: Positive expenditure on soft drinks was highest (50.9% of households). Positive expenditure on bottled water was next for urban households (43.8%) and lowest for rural households (10.8%). Own-price elasticities for all beverages are negative and statistically significant. Own-price elasticity of soft drinks is -1.39, suggesting that with a 10% increase in price, consumption would decrease by 13.9%. Expenditure elasticity for soft drinks (0.99) suggests that a 10% household expenditure increase would result in a 9.9% increase in demand. Milk (0.07) and soft drinks (0.07) have positive quality elasticity implying that, as household total expenditure increases, the quality of these beverages, measured by their unit values, also increases. CONCLUSION: Soft drink demand is highly sensitive to changes in prices, suggesting that SSB taxes could significantly reduce consumption, which, in turn, could contribute to curbing the overweight/obesity epidemic.

RESUMEN

Introduction: Electronic cigarettes (e-cigarettes) have the potential to normalize smoking and undermine tobacco control efforts. However, if well regulated, they also have a potential as smoking cessation aids. This study sought to determine the availability and types of e-cigarettes and e-liquids in Guatemala. We also assessed packaging characteristics and price. Methods: We surveyed a convenient sample of 39 Guatemala City retailers and purchased all e-cigarettes and e-liquids available. Duplicate samples (same brand, e-liquid type, flavor, nicotine content, or packaging) were purchased when prices were different between each other. Country of manufacture, flavor, expiration date, nicotine concentration, and price were recorded. We also documented package marketing strategies and warning labels. Results: We purchased 64 e-cigarettes (53 unique and 11 duplicates) and 57 e-liquids (52 unique and 5 duplicates), mostly found on mall retailers. Most e-cigarettes (42, 66%) were first generation, followed by second (18, 28%) and third generations (4, 6%). Price of e-cigarettes differed significantly by generation. Most e-cigarettes (31, 58%) and 24 (46%) e-liquids did not include warning labels. Nicotine content was reported in 21 (39%) e-cigarettes that included e-liquids and 41 (79%) e-liquids' packages. Conclusions: E-cigarettes and e-liquids are available among a variety of retailers in Guatemala City and the industry is taking advantage of the fact that they are not regulated (eg, health claims, minimum sales age, and taxation). Our findings support the need for further research on e-cigarettes and e-liquids in Guatemala. Implications: To the best of our knowledge, this is the first study describing e-cigarettes and e-liquids available in retailers in a low/middle-income country like Guatemala. E-cigarettes and e-liquids were found in a variety of types, flavors, and nicotine concentrations in Guatemalan retailers. Our findings support the need for further research on e-cigarettes and e-liquids in Guatemala.

RESUMEN

OBJECTIVE: We sought to describe front-of-package marketing strategies and nutritional quality of child-oriented beverages in Guatemala. DESIGN: We purchased all child-oriented ready-to-drink fruit drinks, milks and carbonated beverages in three convenience stores and one supermarket in Guatemala City. Front-of-package marketing was defined as the presence of spokes-characters, cartoons, celebrities, or health-related images, words, claims or endorsements on beverage packaging. We used the UK Nutrition Profiling Model (NPM) to classify beverages as healthy or less healthy. SETTING: Guatemala City, Guatemala. RESULTS: We purchased eighty-nine beverages; most were fruit drinks (n 52, 58 %), milk (15, 17 %), carbonated beverages (5, 17 %), rice/soya products (5, 6·0 %), water (1, 1 %) and energy drinks (1, 1 %). Two-thirds (57, 64 %) had health claims. Of those with a nutrition facts label (85, 96 %), nearly all (76, 89 %) were classified as less healthy. No association between the presence of health claims and NPM score (P=0·26) was found. Eight beverages had health-related endorsements. However, only one beverage was classified as healthy. CONCLUSIONS: In this sample of beverages in Guatemala City, health claims and health-related endorsements are used to promote beverages with poor nutritional quality. Our data support evidence-based policies to regulate the use of front-of-package health claims and endorsements based on nutritional quality.

RESUMEN

OBJECTIVE: The current study sought to examine Guatemalan adolescents' consumption of sugar-sweetened beverages (SSB), identify which individual-level characteristics are associated with SSB consumption and describe school characteristics that may influence students' SSB consumption. DESIGN: Within this observational pilot study, a questionnaire was used to assess students' consumption of three varieties of SSB (soft drinks, energy drinks, sweetened coffees/teas), as well as a variety of sociodemographic and behavioural characteristics. We collected built environment data to examine aspects of the school food environment. We developed Poisson regression models for each SSB variety and used descriptive analyses to characterize the sample. SETTING: Guatemala City, Guatemala. SUBJECTS: Guatemalan adolescents (n 1042) from four (two public, two private) secondary schools. RESULTS: Built environment data revealed that students from the two public schools lacked access to water fountains/coolers. The SSB industry had a presence in the schools through advertisements, sponsored food kiosks and products available for sale. Common correlates of SSB consumption included school type, sedentary behaviour, frequency of purchasing lunch in the cafeteria, and frequency of purchasing snacks from vending machines in school and off school property. CONCLUSIONS: Guatemalan adolescents frequently consume SSB, which may be encouraged by aspects of the school environment. Schools represent a viable setting for equitable population health interventions designed to reduce SSB consumption, including increasing access to clean drinking-water, reducing access to SSB, restricting SSB marketing and greater enforcement of existing food policies.

RESUMEN

BACKGROUND: Overweight prevalence among Guatemalan girls is higher in public than in private schools. Little is known about adolescent girls' perceptions of the right ways to achieve a healthy weight. This study examines public and private school adolescent girls' perceptions of a "healthy weight," and barriers and facilitators to achieving it. METHODS: We conducted 4 focus groups in public and private schools in Guatemala City with girls from 13 to 15 years old. The discussion guide included open-ended questions and activities aimed at examining perceptions of "healthy weight" and barriers and motivators to achieving it within the school environment. Focus groups were audio-recorded and transcribed. Data analyses followed established methods of content analysis. RESULTS: Twenty-eight girls (private school, n = 12; public school, n = 16) of ages ranging from 13.1 to 15.9 years (median, 14, IQR, 13.6-14.9) participated in the study. Girls identified images of thin and fit women as healthy. They cited healthy eating and physical activity as ways to achieve a healthy weight. Within the school environment, barriers to maintaining a healthy weight included a lack of healthy food options and the prioritization of sports for boys over girls. In public schools, facilities were less than optimal; in private schools, girls' access to facilities was limited. Public school girls stated that their uniforms were inappropriate for exercising. CONCLUSION: Our findings support the need to provide more healthy food options in Guatemalan schools. In addition, physical activity for girls should be promoted and facilities made available for their use.

RESUMEN

BACKGROUND: Overweight and obesity prevalence in children is now on the rise in low/middle-income countries, including Guatemala. Fast food consumption is a recognized contributing factor to this rise. Fast food restaurants use health claims, toy giveaways, price incentives and fast service to promote children's combo meals. This study sought to assess the use of toy giveaways, time to delivery and price incentives as marketing strategies in fast food chain restaurants in Guatemala. In addition, we sought to compare nutritional quality of combo meals with and without health claims. METHODS: We visited one restaurant from each of the 8 major fast food chains in Guatemala and purchased all children's combo meals to assess the prevalence of toy giveaways, health claims, and difference in delivery time and price between the combo meal and each meal item purchased separately. Each item was then classified as "healthy" or "less healthy" using the UK Nutrition Profile Model. Nutrition information was collected on-site, from the restaurant website, or by calling the customer service phone number. RESULTS: We found 114 combo meals, 21 (18.4%) of which were children's combo meals. Five (24%) had nutrition information, all were classified by our analysis as "less healthy", and three had a health claim. On average, combo meals were US$1.93 less expensive than purchasing children's meal items individually (p = 0.01). Time to delivery was 1.44 min faster for combo meals compared to purchasing meal items individually (p = 0.19). CONCLUSIONS: Children's fast food combo meals in Guatemala were promoted using several marketing strategies that encourage consumption, including offering toy giveaways and price incentives. In addition, nutrition information is lacking in fast food chain restaurants. Public health advocates in Guatemala should consider a comprehensive approach to encourage healthier choices within fast food restaurants including policies that require fruit and vegetable options for meal side dishes, accessible and easy to read nutrition information, and restrict the use of toy giveaways.

RESUMEN

Obesity in school-age children is emerging as a public heath concern. Food marketing influences preferences and increases children's requests for food. This study sought to describe the type of snack foods advertised to children in stores in and around public schools and assess if there is an association between child-oriented snack food advertising and proximity to schools. All food stores located inside and within a 200 square meter radius from two preschools and two primary schools were surveyed. We assessed store type, number and type of snack food advertisements including those child-oriented inside and outside stores. We surveyed 55 stores and found 321 snack food advertisements. Most were on sweetened beverages (37%) and soft drinks (30%). Ninety-two (29%) were child-oriented. Atoles (100.0%), cereals (94.1%), and ice cream and frozen desserts (71.4%) had the greatest proportion of child-oriented advertising. We found more child-oriented advertisements in stores that were closer (<170 m) to schools compared to those farther away. In conclusion, the food industry is flooding the market, taking advantage of the lack of strict regulation in Guatemala. Child-oriented advertisements are available in almost all stores within a short walking distance from schools, exposing children to an obesogenic environment.

RESUMEN

BACKGROUND: Food marketing is pervasive in high- and low/middle-income countries and is recognized as a significant risk factor for childhood obesity. Although food packaging is one of the most important marketing tools to persuade consumers at the point-of-sale, scant research has examined how it influences children's perceptions. This study was conducted in Guatemala and aimed to understand which snack foods are the most frequently purchased by children and how aspects of food packaging influence their product perceptions. METHODS: Six activity-based focus groups were conducted in two elementary public schools with thirty-seven children (Grades 1 through 6, age range 7-12 years old). During each focus group, children participated in three activities: 1) list their most frequently purchased food products; 2) select the picture of their favorite product, the packaging they liked best, and the product they thought was the healthiest from eight choices; and 3) draw the package of a new snack. RESULTS: Children reported purchasing salty snacks most frequently. Most children chose their favorite product based on taste perceptions, which can be influenced by food packaging. Visual elements influenced children's selection of favorite packaging (i.e., characters, colors) and healthiest product (i.e., images), and persuaded some children to incorrectly think certain foods contained healthy ingredients. When children generated their own drawings of a new product, the most frequently included packaging elements in the drawings were product name, price, product image and characters, suggesting those aspects of the food packaging were most significant to them. CONCLUSIONS: Policies regulating package content and design are required to discourage consumption of unhealthy snacks. This might be another public health strategy that can aid to halt the obesity epidemic.

RESUMEN

BACKGROUND: Childhood overweight in Guatemala is now becoming a public health concern. Child-oriented marketing contributes to increase children's food preference, purchase and consumption. This study sought to assess the availability of child-oriented snack foods sold in school kiosks and convenience stores near public schools in Guatemala, to identify the marketing techniques used in child-oriented snack food packages and to classify the snacks as "healthy" or "less-healthy". METHODS: We purchased all child-oriented snacks found in stores inside and within 200 square meters from four schools in an urban community. Snacks were classified as child-oriented if the package had any promotional characters, premium offers, children's television/movie tie-ins, sports references, or the word "child". We used a checklist to assess child-oriented references and price. Snacks were classified as "healthy" or "less-healthy" according to the UK standards for the Nutritional Profiling Model. RESULTS: We analyzed 106 packages found in 55 stores. The most commonly used technique was promotional characters (92.5%) of which 32.7% were brand-specific characters. Premium offers were found in 34% of packages and were mostly collectibles (50%). Most marketing techniques were located on the front and covered nearly 25% of the package surface. Median (interquartile range) price was US$ 0.19 (0.25). Nutrition labels were found in 91 (86%) packages and 41% had a nutrition related health claim. Most snacks (97.1%) were classified as "less-healthy". CONCLUSION: In Guatemala, the food industry targets children through several marketing techniques promoting inexpensive and unhealthy snacks in the school environment. Evidence-based policies restricting the use of promotional characters in unhealthy snack food packages need to be explored as a contributing strategy to control the obesity epidemic.
