Doença pulmonar obstrutiva crônica e fatores associados em São Paulo, SP, 2008-2009

OBJETIVO: Estimar a prevalência e fatores associados à doença pulmonar obstrutiva crônica. MÉTODOS: Estudo transversal, de base populacional com 1.441 indivíduos de ambos os sexos e com 40 anos de idade ou mais no município de São Paulo, SP, entre 2008 e 2009. As informações foram coletadas por meio de entrevistas domiciliares e os participantes foram selecionados a partir de amostragem probabilística, estratificada por sexo e idade, e por conglomerados em dois estágios (setores censitários e domicílios). Foi realizada regressão múltipla de Poisson na análise ajustada. RESULTADOS: Dos entrevistados, 4,2% (IC95% 3,1;5,4) referiram doença pulmonar obstrutiva crônica. Após análise ajustada, identificaram-se os seguintes fatores independentemente associados ao agravo: número de cigarros fumados na vida (> 1.500/nenhum) RP = 3,85 (IC95%: 1,87;7,94), cansar-se com facilidade (sim/não) RP = 2,61 (IC95% 1,39;4,90), idade (60 a 69 anos/50 a 59 anos) RP = 3,27 (IC95% 1,01;11,24), idade (70 anos e mais/50 a 59 anos) RP = 4,29 (IC95% 1,30;14,29), problemas de saúde nos últimos 15 dias (sim/não) RP = 1,31 (IC95% 1,02;1,77), e atividade física no tempo livre (sim/não) RP = 0,57 (IC95% 0,26;0,97). CONCLUSÕES: A prevalência da doença pulmonar obstrutiva crônica é elevada e está associada ao uso do tabaco e idade acima de 60 anos. Os problemas de saúde freqüentes e redução da atividade física no tempo livre podem ser considerados conseqüências dessa doença.

Social inequalities in health among the elderly

The aim of the present study was to assess social inequalities in health status, health behavior and the use of health services based on education level. A population-based cross-sectional study was carried out involving 1,518 elderly residents of Campinas, São Paulo State, Brazil. Significant demographic and social differences were found between schooling strata. Elderly individuals with a higher degree of schooling are in greater proportion alcohol drinkers, physically active, have healthier diets and a lower prevalence of hypertension, diabetes, dizziness, headaches, back pain, visual impairment and denture use, and better self-rated health. But, there were no differences in the use of health services in the previous two weeks, in hospitalizations or surgeries in the previous year, nor in medicine intake over the previous three days. Among elderly people with hypertension and diabetes, there were no differences in the regular use of health services and medication. The results demonstrate social inequalities in different health indicators, along with equity in access to some health service components.

Narrowing socioeconomic inequality in child stunting: the Brazilian experience, 1974–2007

Objective To assess trends in the prevalence and social distribution of child stunting in Brazil to evaluate the effect of income and basic service redistribution policies implemented in that country in the recent past. Methods The prevalence of stunting (height-for-age z score below \22122 using the Child Growth Standards of the World Health Organization) among children aged less than 5 years was estimated from data collected during national household surveys carried out in Brazil in 1974\201375 (n = 34 409), 1989 (n = 7374), 1996 (n = 4149) and 2006\201307 (n = 4414). Absolute and relative socioeconomic inequality in stunting was measured by means of the slope index and the concentration index of inequality, respectively. Findings Over a 33-year period, we documented a steady decline in the national prevalence of stunting from 37.1 per cent to 7.1 per cent. Prevalence dropped from 59.0 per cent to 11.2 per cent in the poorest quintile and from 12.1 per cent to 3.3 per cent among the wealthiest quintile. The decline was particularly steep in the last 10 years of the period (1996 to 2007), when the gaps between poor and wealthy families with children under 5 were also reduced in terms of purchasing power; access to education, health care and water and sanitation services; and reproductive health indicators.Conclusion In Brazil, socioeconomic development coupled with equity-oriented public policies have been accompanied by marked improvements in living conditions and a substantial decline in child undernutrition, as well as a reduction of the gap in nutritional status between children in the highest and lowest socioeconomic quintiles. Future studies will show whether these gains will be maintained under the current global economic crisis
