Walking and cycling, as active transportation, and obesity factors in adolescents from eight countries.

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.

Food intake, physical activity and body composition of adolescents and young adults: data from Brazilian Study of Nutrition and Health.

BACKGROUND: Lifestyle acquired in youth can determine the individual's health. Constant vigilances in all aspects related to the health of the young population is essential, and evaluate their health parameters is important. The objective of this study was to describe and to compare food intake, physical activity (PA) practice, nutritional status and body composition between adolescents and young adults. METHODS: Four hundred seventy-six individuals from the Brazilian Study of Nutrition and Health (EBANS) were analyzed. Food intake was evaluated by applying two 24-h Dietary Recall. The PA and sitting time (ST) were measured by the International Physical Activity Questionnaire in minutes/week and metabolic equivalent task (METs). Body weight and waist circumference (WC) were measured. Body mass index (BMI) and waist circumference to height ratio (WHtR) were calculated. Mann-Whitney and Chi-Square tests were used. RESULTS: Energy and macronutrients intake, number of meals, and breakfast skippers weren't different between age groups. 48% of adolescents and 53% of young adults didn't meet the PA recommendation, and adolescents practiced more PA than young adults (total PA: p = 0.006; METs: p < 0.001; leisure PA: p = 0.001); the individuals who studied practiced more PA (total PA: p = 0.034; METs: p = 0.029; leisure PA: p < 0.001) and had ST significantly higher (p = 0.009) than those who worked. Almost 30% of adolescents and 45% of young adults had excess weight; presenting difference according to nutritional status, WC and WHtR (p < 0.001). CONCLUSION: There is a high prevalence of excess weight among young Brazilians and differences were observed between age groups regarding nutritional status, body composition and PA practice.

Brazilian Study of Nutrition and Health (EBANS) - Brazilian data of ELANS: methodological opportunities and challenges.

BACKGROUND: Epidemiological studies with dietary variables are complex methodologically, being the researcher responsible for anticipating, controlling, reducing and preventing methodological errors. Obesity accounts for almost one-third of the world's population and has consequences for childhood and adolescence. Multifactorial disorder must be faced in several aspects, being food and physical activity, modifiable risk factors. The EBANS aims to perform a diagnosis of the nutritional status of the Brazilian population from 15 to 65 years old, from all regions, and the parameters associated with obesity, with several possibilities of correlating data. METHODOLOGICAL PROCESS: Part of the ELANS study (n = 9218), the EBANS (n = 2000) has a weighted sample and data collection that allows: to evaluate the socioeconomic level of the population; perform a diagnosis of nutritional status (through anthropometric variables); to evaluate food intake (R24h and FFQ for beverages); and evaluate physical activity practice (IPAQ-long and accelerometer). METHODOLOGICAL OPPORTUNITIES: With national coverage, EBANS has the potential to compose regional analyzes, portray the current nutritional epidemiological condition, food consumption and physical activity pattern of the Brazilian population, at different life stages, and may have their data analyzed together or stratified, offering useful subsidies for the formulation of public policies. METHODOLOGICAL CHALLENGES: Each methodological step was designed to reduce errors and biases related to methodological challenges. CAAE REGISTRATION: 31670314.8.0000.5567. FINAL CONSIDERATIONS: Of great potential for future data analysis, EBANS tries to contribute to the generation of knowledge to foment policies and actions capable of changing the current obesity scenario.

Sim brasil study - women's gastrointestinal health: gastrointestinal symptoms and impact on the brazilian women quality of life / Saúde Gastrointestinal da Mulher: sintomas gastrointestinais e o impacto na qualidade de vida da mulher brasileira

ABSTRACT BACKGROUND Gastrointestinal symptoms seem to affect more women, due to hormonal and emotional issues, impacting the quality of life. The emotional state can affect the bowel functioning through a bidirectional communication system between the gut and the brain involving the neuroendocrine system. Altered bowel functioning and gastrointestinal symptoms can alter quality of life. OBJECTIVE The SIM study aimed to describe, characterize and quantify gastrointestinal symptoms reported by Brazilian women, their causes, feelings and impact. METHODS A structured electronic questionnaire was developed following qualitative phase for semantic formatting, and was administered to volunteer women in ten Brazilian cities. Descriptive and Bayesian statistics analyses were used. RESULTS From the 3029 respondent, 66% reported gastrointestinal symptoms. The most prevalent symptoms were gases (46%), abdominal distention and constipation (43%). The main causes were lifestyle and eating habits. Gastrointestinal symptoms affected quality of life in most women (62%), especially constipation (mood (89%), concentration (88%) and sexual life (79%)). Most common solutions were drinking water, teas, eating foods rich in fiber and probiotics. CONCLUSION Gastrointestinal symptoms are highly prevalent in Brazilian women and negatively impact different aspects of quality of life (mood, concentration and sexuality). The bowel is an important emotional catalyst that can modulate the psychologic behavior. Better understanding of the interaction between the gut and the brain should help in the management of gastrointestinal symptoms to improve women’s quality of life.

RESUMO CONTEXTO Sintomas gastrointestinais parecem afetar mais as mulheres, devido a problemas hormonais e emocionais, afetando a qualidade de vida. O estado emocional pode afetar o funcionamento do intestino por meio de um sistema de comunicação bidirecional entre o intestino e o cérebro que envolve o sistema neuroendócrino. Alterações da função intestinal e sintomas gastrointestinais podem afetar a qualidade de vida. OBJETIVO O estudo SIM teve como objetivo descrever, caracterizar e quantificar os sintomas gastrointestinais relatados por mulheres brasileiras, suas causas, sentimentos e impacto. MÉTODOS Questionário eletrônico estruturado foi desenvolvido após a fase qualitativa para formatação semântica, e foi administrado a mulheres voluntárias em 10 cidades brasileiras. Foram realizadas análises estatísticas descritivas e Bayesiana. RESULTADOS A partir dos 3029 respondentes, 66% relataram sintomas gastrointestinais. Os sintomas mais prevalentes foram gases (46%), distensão abdominal e constipação (43%). As principais causas relatadas foram estilo de vida e hábitos alimentares. Sintomas gastrointestinais afetaram a qualidade de vida da maioria das mulheres (62%), especialmente a constipação (humor (89%), concentração (88%) e vida sexual (79%)). As soluções mais comuns adotadas foram beber água, chás, comer alimentos ricos em fibras e probióticos. CONCLUSÃO Sintomas gastrointestinais são altamente prevalentes nas mulheres brasileiras e impactam negativamente diferentes aspectos da qualidade de vida (humor, concentração e sexualidade). O intestino é um catalisador emocional importante que pode modular o comportamento psicológico. Melhor compreensão da interação entre o intestino e o cérebro pode ajudar na gestão dos sintomas gastrointestinais para melhorar a qualidade de vida das mulheres.
