Factors Associated With Screen Time Among Preschool Children in Lima, Peru.

OBJECTIVE: This study aims to identify factors associated with excessive screen time among preschoolers in Lima, Peru. METHODS: Cross-sectional analysis from a 2019 panel study in Lima, Peru, was conducted focusing on women, aged 18 and above, who are mothers of 3- to 5-year-olds in mid-high and mid-low districts. There were two outcome variables: excessive TV and excessive electronic devices screen time, defined as ≥ 1 h of screen exposure for each one. Explored factors included the mother's age, education and wealth index and the children's age, sex, physical activity, day care attendance and ultra-processed food consumption. Crude (cPR) and adjusted prevalence ratios (aPR) were estimated for the association between associated factors and excessive screen time using the GLM Poisson of with a logarithmic link. RESULTS: Excessive TV screen time and electronic devices prevalence was 74% and 36.9%, respectively. For TV screen time, a high wealth index (aPR 1.13; 95%CI: 1.03-1.23) and children's age (aPR 1.18; 95%CI: 1.08-1.29 for 4 years, PR = 1.17; 95%CI: 1.07-1.28 for 5 years) were significant. For electronic devices, significant associations included mothers with more than 3 children (aPR 0.77; 95%CI: 0.62-0.96), being single (aPR 1.27; 95%CI: 1.01-1.58) and a high wealth index (aPR 1.38; 95%CI: 1.13-1.68). Furthermore, significant associations were found between excessive electronic device screen time and consumption of candies and chocolates (aPR 1.38; 95%CI: 1.08-1.77). CONCLUSIONS: Seven out of 10 preschool children exceeded the recommended television screen time. Certain characteristics of the children, their mothers and the family's socio-economic situation are related to excessive television screen time and excessive electronic device screen time.

The Association Between Lean-to-Fat Mass Ratio and Cardiometabolic Abnormalities: An Analytical Cross-Sectional Study.

Background: Cardiovascular diseases (CVDs) are a global health threat, significantly impacting Latin America. Cardiometabolic abnormalities (CAs), encompassing lipid profile, fasting plasma glucose, and blood pressure, contribute to CVD prevalence. Despite high CA incidence, research in Latin America has primarily focused on traditional adiposity indices, overlooking the intricate relationship between fat and lean body components. The study aimed to analyze the association between the lean-to-fat mass ratio (LFMR) and CAs in the adult Peruvian population. Methods: This was an analytical cross-sectional study using secondary data from the PERU MIGRANT study (2007, 989 participants). The main outcome variable was CA defined as having ≥ 2 out of six metabolic components (high triglycerides, impaired fasting glucose, high blood pressure, low high-density lipoprotein (HDL)-cholesterol, insulin resistance, and high C-reactive protein). The main exposure variable LFMR was divided into tertiles. A generalized linear model was used with log link and robust variance Poisson family to calculate crude (cPR) and adjusted prevalence ratios (aPRs) and 95% confidence intervals (95% CIs). Results: A total of 959 adults aged 30 years or older were included in the analysis (53% females). The prevalence of CA was 50.9%. Females aged 30 - 44 years old showed statistically significant inverse associations for the middle (aPR: 0.57, 95% CI: 0.42 - 0.78) and highest (aPR: 0.22, 95% CI: 0.14 - 0.35) LFMR categories. Similar trends were seen for females aged 45 - 59 years and ≥ 60 years, and males aged 30 - 44 years, while for males aged 45 - 59 years, only the middle LFMR category was associated. No statistically significant association between LFMR and CA was found among old males. Conclusions: LFMR was negatively associated with CA, among the Peruvian adult population. These findings underscore the relevance of LFMR in understanding cardiometabolic health disparities.

Diagnostic Performance of the Measurement of Skinfold Thickness for Abdominal and Overall Obesity in the Peruvian Population: A 5-Year Cohort Analysis.

The escalating prevalence of overall and abdominal obesity, particularly affecting Latin America, underscores the urgent need for accessible and cost-effective predictive methods to address the growing disease burden. This study assessed skinfold thicknesses' predictive capacity for overall and abdominal obesity in Peruvian adults aged 30 or older over 5 years. Data from the PERU MIGRANT 5-year cohort study were analyzed, defining obesity using BMI and waist circumference. Receiver operating characteristic curves and area under the curve (AUC) with 95% confidence intervals (CI) were calculated. Adults aged ≥ 30 (n = 988) completed the study at baseline, with 47% male. A total of 682 participants were included for overall and abdominal obesity analysis. The 5-year prevalence values for overall and abdominal obesity were 26.7% and 26.6%, respectively. Subscapular skinfold (SS) best predicted overall obesity in men (AUC = 0.81, 95% CI: 0.75-0.88) and women (AUC = 0.77, 95% CI: 0.67-0.88). Regarding abdominal obesity, SS exhibited the highest AUC in men (AUC = 0.83, 95% CI: 0.77-0.89), while SS and the sum of trunk skinfolds showed the highest AUC in women. In secondary analysis excluding participants with type-2 diabetes mellitus (DM2) at baseline, SS significantly predicted DM2 development in men (AUC = 0.70, 95% CI: 0.58-0.83) and bicipital skinfold (BS) did in women (AUC = 0.73, 95% CI: 0.62-0.84). The findings highlight SS significance as an indicator of overall and abdominal obesity in both sexes among Peruvian adults. Additionally, SS, and BS offer robust predictive indicators for DM2.

Sodium content in commonly consumed away-from-home food in three areas of Metropolitan Lima, Peru. / Contenido de sodio en preparaciones de consumo frecuente fuera del hogar en tres zonas de Lima Metropolitana, Perú.

The aim of this study was to characterize the sodium content in commonly consumed away-from-home food in three areas of Metropolitan Lima. We conducted a cross-sectional study, in which twenty frequently consumed foods were identified according to the place of sale. Sodium content was determined through atomic absorption spectroscopy in preparations collected in 2019. The median sodium content in street food products was 492.36 mg/100g (IQR: 83.93 - 918.78), 471.37 mg/100 g in artisanal food (IQR: 76.04 - 765.39) and 471.06 mg/100 g in fast food (IQR: 115.31 - 695.18). Sixty-five percent of the foods were classified as having high sodium content according to Peruvian regulations, while 30% of the preparations had high sodium content, according to UK parameters. Most food sold and consumed away from home have high sodium content. It is essential to engage all stakeholders involved in food preparation for away-from-home consumption in order to raise awareness and involve them in the promotion of policies aimed at reducing sodium intake.

El objetivo fue caracterizar el contenido de sodio en preparaciones de consumo frecuente fuera del hogar en tres zonas de Lima Metropolitana. Se realizó un estudio transversal para el cual se identificaron veinte preparaciones de consumo frecuente según el lugar de expendio. La determinación del contenido de sodio se obtuvo mediante espectroscopía de absorción atómica en preparaciones recolectadas en el 2019. La mediana del contenido de sodio en productos de venta ambulatoria fue 492,36 mg/100 g (RIQ: 83,93 - 918,78); 471,37 mg/100 g, en preparaciones tradicionales y típicas (RIQ: 76,04 - 765,39); y 471,06 mg/100 g (RIQ: 115,31 - 695,18), en comidas rápidas. El 65% de las preparaciones fueron consideradas altas en sodio según los parámetros peruanos, mientras que el 30% de las preparaciones también presentaron un alto contenido, de acuerdo con los parámetros del Reino Unido. La mayoría de las preparaciones expendidas y consumidas fuera del hogar presentan un elevado contenido de sodio. Es esencial involucrar a todos los actores que participan en la preparación de alimentos para el consumo fuera del hogar, con el fin de sensibilizarlos e incluirlos en la promoción de políticas enfocadas en la reducción del consumo de sodio.

Design and approval of the nutritional warnings' policy in Peru: Milestones, key stakeholders, and policy drivers for its approval.

Nutritional warnings are used as a public health strategy to address obesity. Peru approved in 2013 and implemented in 2019 a law requiring nutritional warnings on the marketing and packaging of processed foods high in sugar, sodium, saturated fat, and containing trans-fat. The complexity behind the design and approval of these policies over six years provides unique learnings, that inform the obesity prevention context, especially when proposed policies face strong opposition from powerful stakeholders. Our study aims to describe the milestones and key stakeholders' roles and stances during the nutritional warnings policy design in Peru, and to identify and analyze the main drivers of policy change that explain its approval. In 2021, interviews were conducted with 25 key informants closely involved in its design. Interviews were analyzed using the Kaleidoscope Model as a theoretical framework. Relevant policy documents and news were also analyzed. Milestones for this policy included the approval of the Law, Regulation, and Manual. Policy supporters were mainly from Congress, civil society advocates, and Health Ministers. Opponents came from Congress, ministries linked to the economic sector, the food industry, and media. Across the years, warnings evolved from a single text, to traffic lights, to the approved black octagons. Main challenges included the strong opposition of powerful stakeholders, the lack of agreement for defining the appropriate evidence supporting nutritional warning parameters and design, and the political instability of the country. Based on the Kaleidoscope Model, the policy successfully targeted a relevant problem (unhealthy eating decisions) and had powerful advocates who effectively used focusing events to reposition the warnings in the policy agenda across the years. Negotiations weakened the policy but led to its approval. Importantly, government veto players were mostly in favor of the policy, which enabled its final approval despite the strong opposition.

Of the total number of foods with the octagon "Contains trans fats", only 19.2% declared their content. Conclusions. More than a quarter of the beverages and packaged foods in the Peruvian market did not provide nutritional information of any kind, and of those that did, only one did so in different formats and units. In addition, we found that a proportion of beverages and foods for each type of octagon did not declare information of the nutrient that is mentioned in the octagon.

Factors Associated with Normal-Weight Abdominal Obesity Phenotype in a Representative Sample of the Peruvian Population: A 4-Year Pooled Cross-Sectional Study.

To examine factors associated with abdominal obesity among normal-weight individuals from the Demographic and Health Survey of Peru (2018-2021). Cross-sectional analytical study. The outcome variable was abdominal obesity defined according to JIS criteria. Crude (cPR) and adjusted prevalence ratios (aPR) were estimated for the association between sociodemographic and health-related variables and abdominal obesity using the GLM Poisson distribution with robust variance estimates. A total of 32,109 subjects were included. The prevalence of abdominal obesity was 26.7%. The multivariate analysis showed a statistically significant association between abdominal obesity and female sex (aPR: 11.16; 95% CI 10.43-11.94); categorized age 35 to 59 (aPR: 1.71; 95% CI 1.65-1.78); 60 to 69 (aPR: 1.91; 95% CI 1.81-2.02); and 70 or older(aPR: 1.99; 95% CI 1.87-2.10); survey year 2019 (aPR: 1.22; 95% CI 1.15-1.28); 2020 (aPR: 1.17; 95% CI 1.11-1.24); and 2021 (aPR: 1.12; 95% CI 1.06-1.18); living in Andean region (aPR: 0.91; 95% CI 0.86-0.95); wealth index poor (aPR: 1.26; 95% CI 1.18-1.35); middle (aPR: 1.17; 95% CI 1.08-1.26); rich (aPR: 1.26; 95% CI 1.17-1.36); and richest (aPR: 1.25; 95% CI 1.16-1.36); depressive symptoms (aPR: 0.95; 95% CI 0.92-0.98); history of hypertension (aPR: 1.08; 95% CI 1.03-1.13), type 2 diabetes (aPR: 1.13; 95% CI 1.07-1.20); and fruit intake 3 or more servings/day (aPR: 0.92; 95% CI 0.89-0.96). Female sex, older ages, and low and high income levels increased the prevalence ratio for abdominal obesity, while depressive symptoms, living in the Andean region, and fruit intake of 3 or more servings/day decreased it.

OBJECTIVES.: Motivation for the study. Peruvian Law No. 30021 establishes the use of warning octagons for foods with high content of critical nutrients (sugar, sodium, saturated and trans fats); however, the declaration of nutritional information is not mandatory. Main findings. Of a total of 4404 processed and ultra-processed foods marketed in supermarkets in Lima, only 71.4% declared some type of nutritional information. In addition, only 46.0% declared information on the content of critical nutrients regulated by Law No. 30021. Implications. There is a need for a mandatory and standardized declaration of nutritional information on packaged foods marketed in Peru, in order to allow the population to make healthy decisions when choosing their food and to monitor the correct use of warning octagons. . To estimate the number of processed and ultra-processed beverages and foods that provide nutritional information on their packaging, and to describe the characteristics of this information, as well as to determine the presence of nutritional information on products with octagons.

Sugar-sweetened beverage purchases in urban Peru before the implementation of taxation and warning label policies: a baseline study.

BACKGROUND: Sugar-sweetened beverage consumption is associated with obesity and chronic disease. In 2018, Peru increased the tax on high-sugar beverages (≥6 g of sugar per 100 mL) from 17 to 25%, yet little is known about pre-existing beverage trends or demographic characteristics associated with purchases in the country. The aim of this study was to explore beverage purchasing trends from 2016 to 2017 and examine variation in purchase volume by sociodemographic characteristics among urban households in Peru. METHODS: This study used monthly household purchase data from a panel of 5145 households from January 2016-December 2017 from Kantar WorldPanel Peru. Beverage purchases were categorized by type and tax status under the 2018 regulation (untaxed, lower-sugar taxed, high-sugar taxed). To assess beverage purchasing trends, per-capita volume purchases were regressed on a linear time trend, with month dummies for seasonality and clustered standard errors. Mean volume purchases by beverage tax status (total liters purchased per month), overall and by key demographic characteristics (education, socioeconomic status, and geographic region), were calculated. Mean volume by beverage type was assessed to identify the largest contributors to total beverage volume. RESULTS: The trends analysis showed a decline in total beverage volume of - 52 mL/capita/month (95% CI: - 72, - 32) during the 24-month study period. Over 99% of households purchased untaxed beverages in a month, while > 92% purchased high-sugar taxed beverages. Less than half of all households purchased low-sugar taxed beverages in a month and purchase volume was low (0.3 L/capita/month). Untaxed beverage purchases averaged 9.4 L/capita/month, while households purchased 2.8 L/capita/month of high-sugar taxed beverages in 2017. Across tax categories, volume purchases were largest in the high education and high socioeconomic (SES) groups, with substantial variation by geographic region. The highest volume taxed beverage was soda (2.3 L/capita/month), while the highest volume untaxed beverages were milk and bottled water (1.9 and 1.7 L/capita/month, respectively). CONCLUSIONS: Nearly all households purchased high-sugar taxed beverages, although volume purchases of taxed and untaxed beverages declined slightly from 2016 to 2017. Households with high SES and high education purchased the highest volume of taxed beverages, highlighting the need to consider possible differential impacts of the tax policy change by sub-population groups.

Marketing techniques, health, and nutritional claims on processed foods and beverages before and after the implementation of mandatory front-of-package warning labels in Peru.

In June 2019, mandatory front-of-package warning labels (FOPL) were implemented in Peru. The aim of the study was to describe changes in marketing strategies on packaging: marketing techniques (MT), health claims (HC), and nutritional claims (NC) on the packaging of products frequently consumed by children before and after the FOPL implementation. Product photos were taken pre- (March 2019) and post-implementation (March-October 2020) in three supermarkets in Lima, Peru. Following INFORMAS protocols and Peruvian Technical Norms, the presence of MT, HC, and NC was assessed on all package sides. Products were classified as "high-in" and "not high-in" based on the regulation threshold for critical nutrients. Differences in the proportion of products with each strategy in both periods were evaluated. Also, a subsample of products was matched according to the barcode and exact McNemar test was used to compare proportions of strategies pre/post-implementation. We included 883 and 1,035 products in pre- and post-implementation, respectively. In both periods, MT appeared on almost 70% of all products. The presence of HC increased significantly only for beverages (24.5-38.1%, p < 0.001). In both phases, NC were commonly used on beverages (>80%). Overall, the prevalence of "high-in" products using MT increased (73.6-82.1%, p = 0.007), while use of HC increased among "not high-in" products (32.9-41.6%, p < 0.001). There is a high frequency of MT on all products and NC on beverages. The increase in MT in "high-in" products may be an industry response to minimize the impact of the FOPL on food choices and sales. New regulatory aspects regarding labeling should be implemented to strengthen the current policy.

The potential scalability of salt substitutes as an intervention to lower population sodium levels.

Reducing salt intake is one of the most cost-effective interventions to improve population health due to the subsequent reductions in blood pressure. Countries are introducing programs to lower salt consumption. Such programs usually focus on reducing salt in packaged foods and meals alongside campaigns to change consumer behavior. Thus, this paper provides an overview of the rationale for and evidence supporting the use of salt substitutes. Cur-rent approaches to salt reduction are insufficient, and more innovative solutions need to be identified. There is good evidence that salt substitutes, where some of the sodium is replaced with potassium, are effective to lower sodium total intake. The main challenge is to understand the pathways to market for salt substitutes. How do we implement programs to promote salt substitutes in different countries? What levels of government intervention are required? With more research and government investment, salt substitutes could be a game changer for increasing the impact of strategies to reduce population salt intake.

An Experimental Study Evaluating the Influence of Front-of-Package Warning Labels on Adolescent's Purchase Intention of Processed Food Products.

Front-of-package warning labels (WLs) are among the public health policies adopted by some countries, mainly in Latin-America, to tackle childhood obesity; however, their impact is still under review. The aim of this study was to assess, using an experimental design, whether WLs influence purchase intention of processed foods and identification of the healthiest products among adolescents in Peru, in May 2019, just before WLs mandatory implementation. Four hundred forty-nine adolescents from two public schools were randomly assigned to an experimental group (received three different processed products with either zero, one or two WLs, informing if they were high in sugar, sodium and/or saturated fats) or a control group (received the same products but unlabeled). Participants chose which product they would buy, and which they considered to be the healthiest. No differences between groups were found neither in purchase intention (p = 0.386) nor in the identification of the healthiest product (p = 0.322). In both groups, the most-selected product was always the healthiest of the triad (>40% in purchase intention and >80% in identification of the healthiest). Front-of-package WLs did not influence purchase intention, or identification of healthier products among adolescents from public schools in Peru. Mass media and educational campaigns should accompany the WLs implementation to help achieve the policy objective.

Reformulation of Top-Selling Processed and Ultra-Processed Foods and Beverages in the Peruvian Food Supply after Front-of-Package Warning Label Policy.

Front-of-package warning label (FOPWL) policies incentivize the food industry to reduce the content of regulated nutrients in products. We explored changes in the content of nutrients of concern (sugar, saturated fat, trans fat, and sodium) and the percentage of products in the Peruvian food supply that would carry a FOPWL before and after Peru's implementation of FOPWLs. Longitudinal data on the top-selling foods and beverages (n = 94) were collected at three time points: three months before the implementation of the policy, four months after, and two years after. Using the nutritional information declared on products' labels, we compared quantities of nutrients of concern and the percentage of foods that would carry a FOPWL at each time point. Between the first and the third data collection, a decrease in the median sugar content of beverages was observed (from 9.0 to 5.9 g/100 mL, p = 0.005), accompanied by an increase in the use of nonnutritive sweeteners. This change drove the reduction of the percentage of beverages that would carry a FOPWL (from 59 to 31%, p = 0.011). Among foods, decreases were observed in saturated fat (from 6.7 to 5.9 g/100 g, p = 0.002). The percentage of foods that would carry a FOPWL according to their nutritional profile declined from before to after implementation of the policy (from 82 to 62%, p < 0.001). The study shows that the industry reformulated products in Peru after implementation of its FOPWL policy.

Applying Customer Journey Mapping in Social Marketing to Understand Salt-Related Behaviors in Cooking. A Case Study.

Worldwide, salt consumption exceeds the World Health Organization's recommendation of a daily intake of 5 g. Customer journey mapping is a research method used in market research to understand customer behaviors and experiences and could be useful in social marketing as well. This study aimed to explore the potential of customer journey mapping to better understand salt-related behaviors performed during the preparation of household cooking. We tracked the journey of four women in their kitchens for approximately two hours to observe the preparation of lunch. Individual journey maps were created, one for each woman, that were composited into a single journey map. We found that customer journey mapping was a suitable research method to understand how food preparers made decisions around adding salt and artificial seasonings at each stage of the journey. In contrast to the interviewee' responses, it was observed that the four women added salt and artificial seasonings consistently and incrementally with little control and without any standard measure. In this study, we demonstrate the utility of customer journey mapping in a novel context and nudge social marketers to include this tool in their repertory of research methods to understand human behavior.

Changes in the Sodium Content of Foods Sold in Four Latin American Countries: 2015 to 2018.

In 2015, the Pan American Health Organization (PAHO) published sodium targets for packaged foods, which included two distinct levels: one "regional" and one "lower" target. Changes to the sodium content of the food supply in Latin American Countries (LAC) has not been evaluated. A repeated cross-sectional study used food label data from 2015 (n = 3859) and 2018 (n = 5312) to determine changes in the proportion of packaged foods meeting the PAHO sodium targets and the distribution in the sodium content of foods in four LAC (Argentina, Costa Rica, Paraguay, Peru). Foods were classified into the 18 food categories in the PAHO targets. The proportion of foods meeting the regional targets increased from 82.9% to 89.3% between 2015 and 2018 (p < 0.001). Overall, 44.4% of categories had significant decreases in mean sodium content. Categories with a higher proportion of foods meeting the regional and lower targets in 2018 compared to 2015 (p < 0.05) were breaded meat and poultry, wet and dry soups, snacks, cakes, bread products, flavored cookies and crackers, and dry pasta and noodles. While positive progress has been made in reducing the sodium content of foods in LAC, sodium intakes in the region remain high. More stringent targets are required to support sodium reduction in LAC.

Relationship between Marketing to Children on Food Labeling and Critical Nutrient Content in Processed and Ultra-Processed Products Sold in Supermarkets in Lima, Peru.

Consumption of ultra-processed foods has increased alarmingly, representing a risk to children's health. Different techniques in marketing to kids (M2K) used on food labels are influencing the purchasing decisions of these products. This study aims to provide useful information about M2K found in labeling of food products sold in a supermarket chain in Lima, Peru and to determine its relationship with critical nutrient content. This was an observational, correlational, descriptive study. Data were collected by photographing the front-of-pack (FoP) of 2747 product labels sold in three supermarkets in Lima, but only those that met all the inclusion criteria were evaluated (n = 1092). A relationship was found between the use of techniques in marketing to kids and the level of critical nutrient regarding saturated fat (PR = 0.56; CI95%: 0.52-0.63), total sugar (PR = 1.70; CI95%: 1.64-1.77), and sodium (PR = 1.05; CI95%: 1.03-1.07). Particularly with sugar, the presence of M2K is a risk factor. New regulatory policies for the use of these food labeling techniques should be implemented to improve children's health at the population level.

Oferta y publicidad de alimentos y bebidas en instituciones educativas y entornos escolares de Lima Metropolitana. Un estudio exploratorio / Food and beverage supply and advertising in schools and their surroundings in Metropolitan Lima. An exploratory study

Resumen El objetivo del estudio fue describir la oferta y la publicidad de alimentos y bebidas en instituciones educativas y entornos escolares de 15 colegios públicos y privados de Lima en 2019. Se realizaron observaciones inopinadas y se registraron los alimentos ofrecidos, la presencia de advertencias publicitarias, octógonos y la publicidad en quioscos y cafeterías. A la hora de salida se observó la venta ambulatoria de alimentos. Todas las escuelas ofrecían productos ultraprocesados, el 73,3% vendía alimentos con octógonos y el 60% tenía publicidad de alimentos procesados y ultraprocesados. En el 86,7% de los colegios había vendedores ambulantes de alimentos, varios de los alimentos eran productos ultraprocesados. Los resultados sugieren un ambiente alimentario no saludable dentro y alrededor de las escuelas, y el incumplimiento de la regulación actual. Resulta necesario mejorar la difusión y supervisión de la política alimentaria, y construir con las escuelas estrategias para promover una alimentación saludable.

Abstract This study aimed to describe the supply and advertising of foods and beverages both inside educational institutions and in their respective local areas in 15 public and private schools in Lima during 2019. Unbiased observations were recorded regarding the types of food available, the presence of octagons, and advertisements used in kiosks and cafeterias. Mobile food vendors were observed at the end of the school day. All schools offered processed products, 73.3% sold food with octagons, and 60% displayed advertising for processed and ultraprocessed foods. Mobile food vendors were observed in 86.7% of schools, several of which were found to sell ultraprocessed products. The results suggest an unhealthy food environment both inside and outside schools, and a noncompliance with current regulations. It is therefore necessary to improve the dissemination and supervision of the food policy, and develop strategies with schools to promote healthy eating.
