The Association between Exposure to Second-Hand Smoke and Disease in the Chinese Population: A Systematic Review and Meta-Analysis / 生物医学与环境科学（英文）

OBJECTIVE@#To analyze the association between exposure to second-hand smoke (SHS) and 23 diseases, categorized into four classifications, among the Chinese population.@*METHODS@#We searched the literature up to June 30, 2021, and eligible studies were identified according to the PECOS format: Participants and Competitors (Chinese population), Exposure (SHS), Outcomes (Disease or Death), and Study design (Case-control or Cohort).@*RESULTS@#In total, 53 studies were selected. The odds ratio (OR) for all types of cancer was 1.79 (1.56-2.05), and for individual cancers was 1.92 (1.42-2.59) for lung cancer, 1.57 (1.40-1.76) for breast cancer, 1.52 (1.12-2.05) for bladder cancer, and 1.37 (1.08-1.73) for liver cancer. The OR for circulatory system diseases was 1.92 (1.29-2.85), with a value of 2.29 (1.26-4.159) for stroke. The OR of respiratory system diseases was 1.76 (1.13-2.74), with a value of 1.82 (1.07-3.11) for childhood asthma. The original ORs were also shown for other diseases. Subgroup analyses were performed for lung and breast cancer. The ORs varied according to time period and were significant during exposure in the household; For lung cancer, the OR was significant in women.@*CONCLUSION@#The effect of SHS exposure in China was similar to that in Western countries, but its definition and characterization require further clarification. Studies on the association between SHS exposure and certain diseases with high incidence rates are insufficient.

Mortalidade por doenças do aparelho circulatório no município de Ribeirão Preto - SP, de 1980 a 2004 / Mortality rates due to diseases of the circulatory system (DCS) in Ribeirão Preto - SP, from 1980 to 2004 / Mortalidad por enfermedades del aparato circulatorio en el municipio de Ribeirão Preto-SP, del 1980 a 2004

Fundamento: No âmbito da transição epidemiológica, estudos de tendência secular podem subsidiar a formulação de hipóteses para o gerenciamento em Saúde. Objetivo: Identificar o padrão de mortalidade por doenças do aparelho circulatório (DAC) no município de Ribeirão Preto, SP, no período de 1980 a 2004. Métodos: Os óbitos por DAC foram obtidos do Sistema de Informações sobre Mortalidade (SIM). As estimativas populacionais para o município, segundo sexo, faixa etária e anos-calendário, foram obtidas do Instituto Brasileiro de Geografia e Estatística (IBGE). Os coeficientes específicos de mortalidade foram calculados, anualmente, segundo sexo e faixa etária classificada em intervalos de 10 anos, a partir dos 30 anos de idade. O estudo de tendência foi realizado por meio da construção de modelos de regressão polinomial para séries históricas, adotando-se nível de significância < 0,05. Resultados: Os coeficientes específicos de mortalidade por DAC aumentaram com a idade, em ambos os sexos, sendo mais elevados no sexo masculino até a faixa etária de 40 a 49 anos, quando ocorreu aproximação em magnitude, sendo que, na faixa etária de 80 anos ou mais, esses indicadores, no sexo feminino e em alguns anos da série, ultrapassaram os do sexo masculino. Ao longo do período estudado, em ambos os sexos...

Introduction: In terms of epidemiologic transition, century-long trend studies may act as subsidies for health management hypotheses. Objective: Identify mortality rate pattern for diseases of the circulatory system (DCS) in Ribeirão Preto, SP (RP-SP), in the period between 1980 and 2004. Methods: The number of deaths due to DCS were obtained from the Mortality Information System (SIM). Populational estimates for RP-SP - taking gender, age group, and calendar years into account - were obtained from the Brazilian Institute of Geography and Statistics (IBGE). Specific mortality rates were calculated on yearly basis according to gender and age group in 10-year intervals starting at 30 years of age. The trend analysis was conducted through polynomial regression models for time series. Significance level was < 0.05. Results: Specific mortality rates due to DCS increased with age both among males and females, being higher among males in the 40 to 49-year-old range. After that, figures were comparable, although at 80-year-old age groups data for females showed to be higher than that for males in some years of the series. Along the study period, significant reduction was observed for mortality rates among both males and females, and for all age ranges from those causes (p<0.001)...

Fundamento: En el ámbito de la transición epidemiológica, estudios de tendencia secular pueden proveer argumentos a la formulación de hipótesis para el gerenciamiento en la Salud. Objetivo: Identificar el estándar de mortalidad por enfermedades del aparato circultorio (EAC) en el municipio de Ribeirão Preto, SP, en el periodo del 1980 a 2004. Métodos: Se obtuvieron los óbitos EAC en el Sistema de Informaciones sobre Mortalidad (SIM). Se obtuvieron las estimaciones poblacionales para el municipio, según el sexo, el grupo de edad y los años calendarios en el Instituto Brasileiro de Geografia e Estatística (IBGE). Se calcularon anulamente los coeficientes específicos de mortalidad según el sexo y el grupo de edad, clasificados en intervalos de 10 años, a partir de los 30 años de edad. Se realizó un estudio de tendencia a través de la construcción de modelos de regresión polinomial para series históricas, adoptándose el nivel de significancia <0,05. Resultados: Los coeficientes específicos de mortalidad por EAC aumentaron con la edad, en ambos sexos, siendo más elevados en el sexo masculino hasta el grupo de edad de 40 a 49 años, cuando ocorrió aproximación en magnitud, siendo que en el grupo de edad de 80 años y más, esos indicadores, en el sexo femenino y en algunos años...
