OBJETIVO: Identificar a percepção de disponibilidade e oferta de apoio social informal e formal entre idosas de uma localidade de baixa renda do Município do Rio de Janeiro. MÉTODOS: Estudo descritivo, de corte seccional realizado por meio de inquérito domiciliar com 369 (83,5%) idosas da comunidade. RESULTADOS: As mulheres tinham condição social desfavorável (49,3% eram não letrados, 71,3% não tinham companheiro, 62,3% referiram renda mensal de até um salário mínimo e 22,0% não tinham renda). Os tipos de apoio informais mais recebidos foram dinheiro, cuidado pessoal e companhia para se locomover. No entanto, elas se apoiavam no cuidado dos netos, moradia e dinheiro. Apenas 20% declararam receber apoio do Estado ou instituições, destacando-se, sobretudo, a cesta básica. As três principais fontes desses apoios formais foram: governo municipal, Igreja e governo estadual. CONCLUSÃO: O fluxo das relações de troca foi maior no sentido das idosas para suas famílias do que o contrário. Ao cuidar dos netos, as idosas possibilitavam que seus filhos trabalhem e, consequentemente, aumentem a renda familiar. ; OBJECTIVE: To identify the perceived availability and provision of informal and formal social support among elderly women in a low income area of the municipality of Rio de Janeiro.

Purpose: To analyze the factors associated with commuting by bicycling and walking in adult participants from ELSA-Brasil (Longitudinal Study of Adult Health). Design: Cross-sectional. Setting: Six teaching/research institutions throughout Brazil. Participants: A total of 15 105 civil servants. Measures: Commuting by bicycling and walking was analyzed using the long-form International Physical Activity Questionnaire. Analysis: A hierarchical model containing possible factors associated with commuting by bicycling and walking was constructed. Crude and adjusted odds ratios were calculated using multinomial logistic regression. Results: Considering the 2 forms of commuting, 66% of the participants were being considered inactive or insufficiently active. In women, being "heavier," feeling unsafe practicing physical activity, and being a former smoker were factors negatively associated with commuting by bicycling and walking. In men, active commuting was less common among those who were overweight or had abdominal obesity, those with a negative perception of safety, and those reporting that there was nowhere suitable in the neighborhood to practice physical activity. Conclusion: Obesity and negative perceptions in the neighborhood are associated with inactive or insufficiently active commuting. The relevance of this finding for public health is reinforce developing policies aimed at promoting health in Brazil and in other countries with similar characteristics.
