RESUMO

Excessive intake of free sugars is associated with adverse health outcomes. Table sugar is one of the main dietary sources of free sugars; however, the amount added by Brazilian consumers in their culinary preparations is unknown. The aims were to estimate the daily intake of table sugar (g/day), its contribution to total energy intake (E%) and the main food groups that contribute to the intake of this sugar in a nationwide multi-ethnic sample of Brazilian adults (2017-2018 Brazilian National Dietary Survey). Based on two 24-h recalls adjusted for the within-person variation, the overall median table sugar intake was 14.3 g/day, corresponding to 3.2 E%. Males, individuals living in rural areas, with low income, low education and experiencing food insecurity had a higher intake of table sugar. The main food sources of table sugar were coffee (55.8%), juice (33.9%), milk-based preparations and smoothies (3.1%), powdered and processed juice (2.7%), whole milk (1.9%), and tea (1.6%). There are no recommendations regarding the limit of table sugar intake, but considering that the WHO limits the intake of free sugars to <10 E%, it is concluded that table sugar intake by Brazilians corresponds to about 30% of the upper recommended daily intake of free sugars.

RESUMO

BACKGROUND: Feeding difficulties (FDs) are complex phenomena influenced by parental factors, feeding behaviour, and cultural factors. However, studies of the influences of these factors on FDs incidence are scarce. Thus, this study aimed to identify the associations between mothers' perceptions of FDs in children and parental feeding styles, body mass index, and the consumption of fruits, vegetables and processed foods. METHOD: Two hundred and fifty-seven mothers of children aged 1 to 6 years and 11 months participated in this cross-sectional study and self-completed electronic questionnaires on sociographic variables, parental feeding styles, the consumption of fruits, vegetables and processed foods and FDs. Nutritional status was classified by body mass index (kg/m2). RESULTS: The prevalence of FDs in children was 48.2%, and the mean age was 43.8 (± 17.6) months. The indulgent parental feeding style was the most common (40.1%), followed by the authoritative (31.1%), authoritarian (23.7%), and uninvolved (5.1%) styles. An indulgent parental feeding style (OR: 4.66; 95% CI: 2.20-9.85), a high body mass index (OR: 1.35; 95% CI: 1.09-1.68), and the consumption of processed foods (OR: 5.21; 95% CI: 2.85-9.53) were positively associated with increased odds of the absence of FDs in children. The associations of authoritarian and uninvolved parental feeding styles and the consumption of fruits and vegetables with FDs in children were not significant. CONCLUSION: This study identified multiple factors that are possibly associated with feeding behaviours in young children. However, further studies need to be undertaken to evaluate how such behaviours affect FDs.

RESUMO

Assessing dietary inadequacies can contribute to understanding the nutritional vulnerabilities of a country. This study aimed to investigate nutrient intakes and micronutrient inadequacies in the Brazilian adult population, with an interest in different age subgroups. We conducted a cross-sectional study with 1812 individuals aged 19 to 65 years from a population-based study with a representative sample of Brazilian adults. Dietary intake was assessed by two 24 h food recalls, and the probabilities of inadequate intake were estimated using the Dietary Reference Intake targets. Adequate macronutrient intake was over 99% for proteins, 84.7% for carbohydrates, and 80.7% for total fats. There was a high probability of inadequacy (above 90%) for vitamins D and E, but vitamin D inadequacy was very similar between the sexes. In contrast, vitamin E was more likely to be inadequately consumed among women. A high probability of inadequacies (above 85%) of calcium and magnesium were found in the population, regardless of age group. Except for iron, the probability of an inadequacy of other minerals increased with age. The results showed a relevant proportion of nutrient inadequacies, with those most at risk being women and older individuals, helping with the better targeting and monitoring of public-health policies that address nutritional problems in the population.

RESUMO

Introduction: Energy imbalance gap (EIG) is defined as the average daily difference between energy intake (EI) and energy expenditure (EE). This study aimed to examine the associations between EIG and sociodemographic and anthropometric variables in the adolescent population of eight Latin America countries. Methods: A total of 680 adolescents aged 15 to 18 were included in this study. The estimation of EI was based on two non-consecutive 24-h dietary recalls. EE was predicted from Schofield equations using physical activity level obtained through the long version of the International Physical Activity Questionnaire. Sociodemographic data and anthropometric measurements were also obtained. A descriptive analysis and multilevel linear regression models were used to examine associations between variables. Results: The mean EI, EE, and EIG were 2091.3 kcal, 2067.8 kcal, and 23.5 kcal, respectively. Argentina had the highest EI and EIG, whereas Chile had the lowest EI and EIG. Males had a higher EI (2262.4 kcal) and EE (2172.2 kcal) than females (1930.1 kcal and 2084.5 kcal), respectively (p < 0.05). Overweight subjects had a lower EIG than did underweight and normal-weight subjects (p < 0.05). Subjects with low socioeconomic status (SES) had a lower EE (2047.0 kcal) than those with a high SES (2164.2 kcal) (p < 0.05). Conclusion: Sex and BMI were associated with EIG in adolescents from Latin America.

RESUMO

This study verified the diagnostic accuracy of the nutritional status classified by the international height and BMI references of the World Health Organization (WHO) (WHO/2007), International Obesity Task Force (IOTF/2012) and MULT (2023). The data pool was composed by 22 737 subjects aged five to 16 years from the Santos and Porto Alegre surveys. A correlation matrix between the z-scores of the BMI references and the skinfold measurements was calculated through the Pearson correlation coefficient (r), and the subject's nutritional status was classified according to the international growth references. The accuracy for diagnosing obesity was performed separately by sex and using the 95th percentile of the triceps and subscapular skinfold sum, while Lin's concordance coefficient, Bland-Altman method and the Cohen's Kappa coefficient (Kappa) were used to verify the concordance and reliability among the BMI references. The correlation matrix showed a high positive correlation among the BMI z-scores (r ≥ 0·99) and among the skinfold measurements (r ≥ 0·86). The prevalence of stunting was higher when applying the MULT reference (3·4 %) compared with the WHO reference (2·3 %). The Bland-Altman plots showed the lowest critical difference (CD) between the height references of WHO and MULT (CD = 0·22). Among the BMI references, the WHO obesity percentile presented lower performance than MULT for boys, presenting a lower +LR value (WHO = 6·99/MULT 18 years = 10·99; 19 years = 8·99; 20 years = 8·09) for the same -LR values (0·04). Therefore, MULT reference holds promise as a valuable tool for diagnosing childhood obesity, particularly when considering sex differences. This enhances its suitability for assessing the nutritional status of Brazilian schoolchildren.

RESUMO

OBJECTIVE: To investigate the relationship between the biopsychosocial environment and eating habits and behaviors that lead to the selection and consumption of certain food from the earliest stages of life. To clarify whether there is an interaction between genetic and epigenetic factors, and how they shape eating habits. DATA SOURCE: A narrative review based on research in PubMed and Web of Science electronic databases was carried out over the last 10 years, searching the title and summary fields using the keywords Children OR adolescents Feeding Behavior eating OR Dietary Habits OR Eating Behavior OR Eating Habits OR Children obesity. DATA SYNTHESIS: The generational transmission of eating habits is related to the home, community, and school environments, mainly during the first years of life, and can exert the modulation of habits during all stages of life. During childhood, the family's role in consolidating eating habits is very broad and ranges from choosing foods to prioritizing family meals, including the lifestyle. CONCLUSIONS: Eating habits are transmitted from parents to children in different ways: environmental, emotional, social, and educational. In cases of obesity, a greater association of genetic influence can be observed.

RESUMO

BACKGROUND: Latin American countries have shifted from traditional diets rich in micronutrients to a Westernized diet rich in high energy-dense foods and low in micronutrients. OBJECTIVE: This study aimed to determine the prevalence of adequate micronutrient intakes in urban populations of 8 Latin American countries. METHOD: Micronutrient dietary intake data were collected from September 2014 to August 2015 from 9216 men and women aged 15.0 to 65.0 years living in urban populations of 8 Latin American countries. Dietary intake was collected using two 24-hour recalls on nonconsecutive days. Micronutrient adequacy of intake was calculated using the Estimated Average Requirement cut-off method. RESULTS: In general terms, the prevalence of inadequate intake of thiamine, riboflavin, niacin, folate, cobalamin, iron, phosphorus, copper, and selenium ranged from 0.4% to 9.9%. In contrast, the prevalence of inadequacy of pyridoxine, zinc, vitamin C, and vitamin A ranged from 15.7% to 51.5%. The nutrients with a critical prevalence of inadequacy were magnesium (80.5%), calcium (85.7%), and vitamin D (98.2%). The highest prevalence of inadequate intakes was observed in the low educational level, participants with overweight/obesity, in men, and varies according to socioeconomic status. CONCLUSIONS: There is an urgent need to define direct regional actions and strategies in Latin America aimed at improving micronutrient adequacy, either through staple food fortification programs, agronomic biofortification, or food policies that facilitate economic access to micronutrient-rich foods.


Plain language titleDescription of the Vitamin and Mineral Consumption Status in Urban Cities of Latin America: Results of the Latin American Health and Nutrition Study.Plain language summaryVitamins and minerals are essential for maintaining good health. However, traditional Latin American diets are changing to include foods that have a lot of sugar and fat but fewer vitamins and minerals. This study was designed to analyze the consumption of these nutrients in urban cities of 8 Latin American countries. We collected food consumption information from September 2014 to August 2015 from 9216 men and women between 15 and 65 years old using a method called 24-hour recall. To find out if participants were consuming the necessary daily amounts of vitamins and minerals, intakes were compared with the daily recommended amounts suggested by the Institutes of Medicine of the United States. We found that Latin American urban populations consume fewer vitamins and minerals than recommended. In some cases, few people do not consume the required amounts of vitamins and minerals, but in other cases, many do not. For example, few do not consume enough thiamine, riboflavin, niacin, folate, cobalamin, iron, phosphorus, copper, and selenium. However an intermediate number of people do not consume enough pyridoxine and zinc, a high number consume little vitamin C and vitamin A, and many people consume very little magnesium, calcium, and vitamin D. We found that the people who consume fewer vitamins and minerals are mostly males, overweight/obese, have lower education and varies according to their financial resources. A deficient intake of vitamins and minerals showed up in most age groups, from adolescence to adulthood. To improve vitamins and minerals intake, it is important that some foods that are frequently eaten are fortified or that the price of foods that are high in vitamins and minerals is lowered.

RESUMO

BACKGROUND: Parental complaints about feeding difficulties (FD) during childhood are frequent in pediatrics. Behavioral factors about children's feeding and parental aspects are fundamental in solving these problems, but research in this area lacks information considering the joint presence of fathers and mothers. Thus, this study aimed to investigate the features of children, parents and mealtime practices related to FD reported by fathers and mothers and to identify parenting styles, mealtime actions, practices and factors associated with FD in children. METHODS: 323 parents (226 mothers and 97 fathers) of children aged 1 to 7 years were recruited in the emergency waiting room at Sabará Hospital Infantil, in São Paulo, Brazil, and self-completed electronic questionnaires on parenting style (Caregiver's Feeding Styles Questionnaire), parents' mealtime actions (Parent Mealtime Action Scale), socioeconomic information, personal and children's health data and routine meal practices. RESULTS: The prevalence of FD in children was 26.6%. Indulgent parenting style was the most frequent (44.2%), followed by authoritarian (25.1%), authoritative (23.8%), and uninvolved (6.9%) styles. Most parents (75.8%) reported presence during meals, and 83.6% used distractions. Regression analyses after adjustments showed, as factors associated with FD, female children (OR: 2.06; 95%CI: 1.19-3.58), parents' FD history (OR: 3.16; 95%CI: 1.77-5.64), and greater frequency of parents' behavior of offering many food options (OR: 2.69; 95%CI: 1.18-6.14). Parents with indulgent styles had decreased chances of reporting FD in their children (OR: 0.13; 95%CI: 0.06-0.27). Furthermore, the practice of children sharing the family menu (OR: 0.43; 95%CI: 0.18-0.99) and higher frequency of parents' behavior of setting snack limits (OR: 0.44; 95%CI: 0.23-0.85) were inversely associated with FD. CONCLUSIONS: This study reinforces the multifactorial aspects involved in the feeding difficulties context. It points out the importance of expanding knowledge of the individual role of fathers and mothers to compose a scenario that can guide future studies and interventions.

RESUMO

Recent studies have shown various relationships between physical activity and the incidence of obesity, but this study critically explored the association of sedentary time (ST) and moderate-to-vigorous physical activity (MVPA) with obesity risk in adults from eight Latin American countries. ST and MVPA were assessed with accelerometers and stratified into 16 joint categories. Multivariate logistic regression models were used. The obesity risk indicators evaluated were body mass index (BMI), waist circumference (WC), and neck circumference (NC). Quartile 4 of ST and ≥300 min/week of MVPA was associated with lower odds of BMI compared to quartile 1 of ST and ≥300 min/week of MVPA. Quartile 1 of ST and 150-299 min/week of MVPA, quartile 1 of ST and 76-149 min/week MVPA, quartile 3 of ST and 76-149 min/week MVPA, and quartiles 1, 2, and 3 of ST with 0-74 min/week MVPA were associated with higher odds of high WC compared to quartile 1 of ST and ≥300 min/week of MVPA. Quartile 3 of ST and 150-299 min/week of MVPA, quartiles 1 and 3 of ST and 76-149 min/week of MVPA, and quartile 1 of ST and 0-74 min/week MVPA were associated with higher NC compared to quartile 1 of ST and ≥300 min/week of MVPA. This study suggests that achieving the MVPA recommendations will likely protect against obesity, regardless of ST.

RESUMO

Dietary protein intake is vital to life. Here we sought to characterize dietary sources of protein in eight Latin American countries. Survey data were collected for Estudio Latinoamericano de Nutrición y Salud (ELANS); participants were from Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela (n = 9218, 15-65 years old). The primary aim of this analysis was to quantify per-person daily protein consumption by country and sociodemographic factors. Secondary aims: to quantify proportional intake of proteins by source, amount and processing, and to determine the adequacy of protein/essential amino acid intake. Younger groups (adolescents 15-19 years, adults 20-33 years) had the highest intake of proteins; middle-aged adults (34-49 years) had a lower intake, and older adults (50-65 years) had a strikingly lower intake. Protein consumption was higher in men than women. Animal proteins comprised nearly 70% of total daily protein intake in Argentina and Venezuela, contrasting with <60% in Peru, Chile, and Costa Rica. Brazil and Venezuela showed the highest protein intake within the highest education level. The higher the socioeconomic level, the higher the protein intake, except for Argentina, Chile, and Peru. Proportional intake of animal- and plant-based protein generally reflected the food availability by country. This study presents a pre-pandemic regional baseline and offers a perspective for future studies of changes related to government policies, climate, and dietary practices.

RESUMO

BACKGROUND: Excess weight is increasing worldwide, and in Latin America more than half of the population is excess weight. One of the reasons for this increase has been excessive sitting time. Still, it remains to be seen whether there is an excessive amount of that time in Latin American adults. This study aimed to associate different sitting time cut-off points with the excess weight. METHODS: Data from the Latin American Study of Nutrition and Health (ELANS), a cross-sectional population-based survey conducted in eight Latin American countries, were used. The excess weight indicators used were body mass index, and waist and neck circumferences. Sitting time was obtained using questionnaires and categorized at different cut-off points. Differences between sitting time categories (< 4 or ≥ 4; < 6 or ≥ 6; and < 8 or ≥ 8 hours/day) and excess weight were obtained by Student's t test for independent samples and the association between sitting time categories and different indicators of excess weight were obtained by logistic regression. RESULTS: The median of the sitting time was 420 min/day (IQR: 240-600). There were no significant differences between body mass index (kg/m2) and waist circumference (cm) with categories of sitting time. The mean values of neck circumference (cm) were significantly higher in ≥4, ≥6 and ≥ 8 hours/day than < 4, < 6, and < 8 hours/day of sitting time in the pooled sample. Some distinct differences by country were observed. There were significant differences among excess weight by body mass index (63.2% versus 60.8) with < 8 vs ≥8 hours/day of sitting time. The proportion of excess weight by neck circumference was higher in participants who reported ≥4, ≥6, and ≥ 8 hours/day compared to < 4, < 6, and < 8 hours/day of sitting time. Considering ≥8 hours/day of sitting time, higher odds of excess weight were found evaluated by body mass index (OR: 1.10; 95% CI: 1.01, 1.20) and neck circumference (OR: 1.13; CI 95%: 1.03, 1.24) overall. CONCLUSIONS: Sitting time above 8 hours/day was associated with higher odds of excess weight, even though there were no differences in waist circumference between sitting time categories. TRIAL REGISTRATION: Clinical Trials NCT02226627. (27/08/2014).

RESUMO

ABSTRACT Objective To describe the prevalence of inadequate mineral intake and associated factors with calcium, iron, zinc, magnesium, phosphorus, and sodium intakes in individuals aged 15-24.9 years. Methods We analyzed 476 individuals from the Brazilian Study of Nutrition and Health, stratified into two age groups (adolescents aged 15-18.9 years and young adults aged 19-24.9 years). Mineral intake was obtained from two 24-hour Dietary Recalls. The values of the Estimated Average Requirement and the Tolerable Upper Intake Levels were considered to calculate the prevalence of inadequacy. Multiple logistic regression was used to determine associated factors with mineral intake. Results Calcium and magnesium had the highest prevalence of inadequacy (>83%) in both sexes and age groups. Sodium intake was above Tolerable Upper Intake Levels for the majority of the population studied (>68%). The intake of all minerals was different between the sexes for the two age groups (p<0.01), and it was not different between age groups (p>0.05). The associated factors with mineral intake were sex (calcium, iron, phosphorus, and sodium), age group (calcium, magnesium, phosphorus, and sodium), and physical activity (calcium, iron, and magnesium), followed by socioeconomic level (zinc and sodium) and body weight status (iron and sodium). Conclusion The expressive portion of the studied population is at nutritional risk for calcium, magnesium, and sodium. Such data can contribute to the national public policy revision that is related to micronutrient intake and the adoption of healthier habits by adolescents and young adults.


RESUMO Objetivo Descrever as prevalências de inadequação e fatores associados à ingestão de cálcio, ferro, zinco, magnésio, fósforo e sódio em indivíduos dos 15 aos 24,9 anos. Métodos Foram analisados 476 indivíduos do Estudo Brasileiro de Nutrição e Saúde, estratificados em dois grupos etários (adolescentes de 15-18,9 anos e adultos jovens de 19-24,9 anos). A ingestão de minerais foi obtida por meio de dois recordatórios de 24hs. Os valores de Requerimento Médio Estimado e do Limite Superior Tolerável de Ingestão foram considerados para calcular as prevalências de inadequação. Regressão logística múltipla foi utilizada para determinar os fatores associados à ingestão de minerais. Resultados Cálcio e magnésio tiveram elevadas prevalências de inadequação (>83%) em pacientes de ambos os sexos e grupos etários. A ingestão de sódio foi acima Limite Superior Tolerável de Ingestão para a maioria da população estudada (>68%). O consumo de todos os minerais foi diferente entre os sexos para os dois grupos etários (p<0,01) e não foi diferente entre os grupos etários (p>0,05). Os fatores associados à ingestão dos minerais foram sexo (cálcio, ferro, fósforo e sódio), grupo etário (cálcio, magnésio, fósforo e sódio) e atividade física (cálcio, ferro e magnésio), seguidos por nível socioeconômico (zinco e sódio) e estado de peso corporal (ferro e sódio). Conclusão Expressiva parcela da população estudada encontra-se em risco nutricional para cálcio, magnésio e sódio. Esses dados podem contribuir para a revisão de políticas públicas nacionais que se relacionam à ingestão de micronutrientes e à adoção de hábitos mais saudáveis pelos adolescentes e adultos jovens.

RESUMO

This study aimed to examine the association between the neighborhood environment and domain-specific physical activity and sitting time in Brazilian adults. This cross-sectional study included 1803 adults (53.7% women) from Brazil's five regions (North, Northeast, Midwest, Southeast and South). The perception of the environment was evaluated via a questionnaire. We considered seven indicators of the neighborhood environment: land use mix-diversity, land use mix-access, street connectivity, walking/cycling facilities, aesthetics, safety from traffic and safety from crime. Using the IPAQ, we evaluated physical activity (transport and leisure) and sitting time. Overall, land use mix-diversity (ß = 3.22; 95% CI = 0.26, 6.19), land use mix-access (ß = 2.27; 95% CI = 0.76, 3.79), and walking/cycling facilities (ß = 2.42; 95% CI = 0.35, 4.49) were positively associated with leisure-time physical activity (min/week). On the other hand, only land use mix-diversity (ß = 3.65; 95% CI = 0.63, 5.49) was positively associated with transport physical activity (min/week). No neighborhood environment indicator was associated with sitting time (min/day). Perception of the neighborhood environment was associated with physical activity (transport and leisure), while no significant associations occurred with sitting time among the five regions of Brazil. The neighborhood environment can be a viable component in the promotion of physical activity, but geographic diversity must be considered.

RESUMO

This study aims to establish cut-off points for the number of minutes of physical activity intensity and the number of daily steps that identify overweight/obesity in adolescents, adults, and older adults. This study examined data from 2737 participants. Physical activity intensity and the number of daily steps were assessed using GT3X+ ActiGraph model accelerometers. Body mass index, waist-to-height ratio, and waist-to-hip ratio were used as indicators of overweight/obesity. The cut-off points for moderate-to-vigorous physical activity for the prevention of overweight/obesity according to body mass index in women ranged from 15.1 to 30.2 min/day; in men, the values were from 15.4 to 33.8 min/day. The lowest cut-off point for daily steps was established in the adolescent group for women and men (7304 and 5162). The highest value in women was 11,412 (51-65 years) and 13,234 in men (18-30 years). Results from measurements different from BMI, show average cut-off points for moderate-to-vigorous physical activity and daily steps of 29.1/8348 and 43.5/10,456 according to waist-to-height ratio; and results of 29.3/11,900 and 44.3/11,056 according to the waist-to-hip ratio; in women and men respectively. A more specific recommendation of physical activity and daily steps adjusted by sex and age range is suggested to prevent overweight/obesity.

RESUMO

This study examines the associations between perceived urban environment attributes and obesity indices by country using data from an eight-nation study from Latin America. The data were collected from 8185 adults. The Neighbourhood Environment Walkability-abbreviated scale was used to assess perceived urban environment attributes. Obesity indices considered were body mass index, waist circumference, neck circumference, a body shape index and waist-to-height ratio. The perception of a more and better land use mix-diversity (ß - 0.44; 95% CI - 0.59, - 0.28), traffic safety (- 0.39; - 0.66, - 0.12), and safety from crime (- 0.36; - 0.57, - 0.15) was associated with lower body mass index across the entire sample. Land use mix-diversity (- 1.21; - 1.60, - 0.82), street connectivity (- 0.26; - 0.37, - 0.15), and traffic safety (- 0.79; - 1.47, - 0.12) were negatively associated with waist circumference. Land use mix-diversity (- 0.11; - 0.20, - 0.03), land use mix-access (- 0.23; - 0.34, 0.12), walking/cycling facilities (- 0.22; - 0.37, - 0.08), and safety from crime (- 0.27; - 0.42, - 0.12) were negatively associated with neck circumference. No associations between perceived urban environment attributes and a body shape index were found. Land use mix-diversity (- 0.01; - 0.02, - 0.01), aesthetics (- 0.02; - 0.03, - 0.01), and safety from crime (- 0.02; - 0.04, - 0.01) were associated with waist-to-height ratio. Environmental interventions involving urban environment attributes are associated with obesity indices and, therefore, may help decrease the prevalence of overweight and obesity.

RESUMO

Neighborhood built environment is associated with domain-specific physical activity. However, few studies with representative samples have examined the association between perceived neighborhood safety indicators and domain-specific active transportation in Latin America. This study aimed to examine the associations of perceived neighborhood safety with domain-specific active transportation in adults from eight Latin American countries. Data were obtained from the Latin American Study of Nutrition and Health (n = 8547, aged 18-65). Active transportation (walking and cycling) was assessed using the long form of the International Physical Activity Questionnaire. Specifically, traffic density and speed as well as street lightening, visibility of residents regarding pedestrians and bicyclists, traffic lights and crosswalks, safety of public spaces during the day and at night, crime rate during the day and at night were used to evaluate perceived neighborhood safety. Slow traffic speeds, unsafe public spaces during the day, and crime during the day were associated with ≥10 min/week vs. <10 min/week of walking. Furthermore, drivers exceeding the speed limit and crime rate during the day were associated with reporting ≥10 min/week vs. <10 min/week of cycling. These results indicate a stronger association of the perceived neighborhood safety with walking compared to cycling.

RESUMO

Excessive sodium intake has been related to high blood pressure, a central risk factor for cardiovascular disease. In the present work, updated estimates of sodium intake, the main food sources, and the prevalence of excessive intakes in a nationwide multi-ethnic sample of Brazilian adults (2017-2018 Brazilian National Dietary Survey) were presented. Based on two 24-h recalls adjusted for the within-person variation, the overall median of sodium intake was 2432 mg. The prevalence of adults exceeding the recommended limits (tolerable upper limit, UL, and the chronic disease risk reduction cut-off point, CDRR) was 61% and 56%, respectively. The median sodium intake and proportion of individuals above the limits varied according to the subgroups evaluated. Males and adults (20-29 years) presented the highest excessive sodium intakes, and consequently, lowest adherence rates to UL and CDRR recommendations. The top food sources of sodium were white bread and toast (12.3%), beans (11.6%), white rice (10.6%), beef (7.7%), and poultry meat (5.5%). Given the health benefits of dietary sodium reduction, it would be advisable to enhance the current national initiatives of awareness and educational campaigns' combined efforts to reduce sodium in processed foods to effectively decrease this micronutrient intake across the Brazilian population.

RESUMO

BACKGROUND: Evidence has shown that active transportation decreases obesity rates, but considering walking or cycling as separate modes could provide additional information on the health benefits in adolescents. This study aimed to examine the associations between walking and cycling as form active transportation and obesity indicators in Latin American adolescents. METHODS: Population-based study with 671 adolescents (mean age: 15.9 [standard deviation: 0.8] years) from eight countries participating in the Latin American Study of Nutrition and Health/Estudio Latino Americano Nutrition y Salud (ELANS). Walking and cycling for active transportation were measured using the International Physical Activity Questionnaire long version. Body mass index, waist circumference, neck circumference, and relative fat mass were used as obesity indicators. Associations were estimated using logistic regression models for the pooled data adjusted for country, sex, age, socio-economic levels, race/ethnicity, leisure-time physical activity and energy intake. RESULTS: Mean time spent walking and cycling was 22.6 (SD: 33.1) and 5.1 (SD: 24.1) min/day, respectively. The median values were 12.8 (IQR: 4.2; 25.7) and 0 (IQR: 0; 6.2) for walking and cycling. Participants reporting ≥ 10 min/week of walking or cycling for active transportation were 84.2% and 15.5%, respectively. Costa Rica (94.3% and 28.6%) showed the highest prevalence for walking and cycling, respectively, while Venezuela (68.3% and 2.4%) showed the lowest prevalence. There was no significant association between walking for active transportation and any obesity indicator. In the overall sample, cycling for ≥ 10 min/week was significantly associated with a lower likelihood of overweight/obesity based on BMI (OR: 0.86; 95%CI: 0.88; 0.94) and waist circumference (OR: 0.90; 95%CI: 0.83; 0.97) adjusted for country, sex, age, socio-economic level, race/ethnicity, leisure-time physical activity and energy intake compared to cycling for < 10 min/week. There were no significant associations between cycling for active transportation and neck circumference as well as relative fat mass. CONCLUSIONS: Cycling for active transportation was negatively associated with obesity indicators, especially body mass index and waist circumference. Programs for promoting cycling for active transportation could be a feasible strategy to tackle the high obesity rates in adolescents in Latin America. TRIAL REGISTRATION: ClinicalTrials.Gov NCT02226627. Retrospectively registered on August 27, 2014.

RESUMO

This study aimed to compare compliance with 24-h movement guidelines across countries and examine the associations with markers of adiposity in adults from eight Latin American countries. The sample consisted of 2338 adults aged 18-65 years. Moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) data were objectively measured using accelerometers. Sleep duration was self-reported using a daily log. Body mass index and waist circumference were assessed as markers of adiposity. Meeting the 24-h movement guidelines was defined as ≥ 150 min/week of MVPA; ≤ 8 h/day of SB; and between 7 and 9 h/day of sleep. The number of guidelines being met was 0.90 (95% CI 0.86, 0.93) with higher value in men than women. We found differences between countries. Meeting two and three movement guidelines was associated with overweight/obesity (OR: 0.75, 95% CI 0.58, 0.97 and OR: 0.69, 95% CI 0.51, 0.85, respectively) and high waist circumference (OR: 0.74, 95% CI 0.56, 0.97 and OR: 0.77, 95% CI 0.62, 0.96). Meeting MVPA and SB recommendations were related to reduced adiposity markers but only in men. Future research is needed to gain insights into the directionality of the associations between 24-h movement guidelines compliance and markers of adiposity but also the mechanisms underlying explaining differences between men and women.
