Smokers who were seen by a doctor or other healthcare provider for any health concern in Brazil: what a missed opportunity to encourage smoking cessation!

OBJECTIVES: This study aimed to examine changes in the proportion of smokers who were advised to quit smoking by health professionals as part of routine consultations or interactions with their patients between 2008 and 2019. STUDY DESIGN: Serial cross-sectional study. METHODS: Data from two nationally representative cross-sectional surveys were used to examine changes over time in the proportions of smokers who were seen by a doctor or other healthcare provider for any health concern and were advised to quit smoking ('Advice_HP'). An additional dichotomous variable ('AdviceAccess_HP') was created and included smokers who were not seen by a doctor or other healthcare provider in the past 12 months in the 'no advice' received category. Crude and adjusted absolute differences in prevalence rates of smokers who were advised to quit smoking by health professionals as part of routine consultations or interactions with their patients between 2008 and 2019 were evaluated using a generalised linear model. RESULTS: The proportion of smokers who were seen by a health professional for any health concern increased from 58.8% in 2008 to 88.7% in 2019. The proportion of 'AdviceAccess_HP' increased from 33.6% in 2008 to 45.2% in 2019; however, the proportion of 'Advice_HP' decreased from 57.1% in 2008 to 51.0% in 2019. After adjustment for sociodemographic and smoking behaviour characteristics, differences remained virtually unchanged. In 2019, health professionals missed the opportunity to provide around 10 million smokers with brief advice to stop smoking. CONCLUSIONS: Monitoring the actions needed to encourage smoking cessation is critical for achieving the United Nations sustainable development goals. Primary healthcare workers should serve as role models for patients and provide brief advice that increases the likelihood of successfully quitting tobacco use, particularly in low- and middle-income countries.

A snapshot of the striking decrease in cigarette smoking prevalence in Brazil between 1989 and 2008.

OBJECTIVE: To evaluate the differences in cigarette smoking prevalence rates in Brazil between 1989 and 2008. METHODOLOGY: We calculated absolute and relative differences in smoking prevalences, overall and stratified by gender, age, place of residence, educational level and birth cohort. Data were obtained from random samples from two National Household Surveys (1989,n=39,969; 2008,n=38,461). GLM models were specified to obtain estimates and assess whether differences in proportions of smokers differed by categories of the stratification variables. RESULTS: Adjusted absolute and relative differences in smoking prevalence rates between 1989 and 2008 were, respectively, -12.4% and -41.0%. Individuals aged 15-34 years and those with 9 or more years of education presented larger relative declines than their counterparts (p(s)≤0.001). After stratification by birth cohort, men presented larger reductions than women, only in the absolute scale (p(s)≤0.001), with the exception of the youngest birth cohort (i.e.,1965-1974). CONCLUSIONS: In Brazil, several tobacco control measures have been adopted since 1986, in particular increasing taxation of tobacco products and strong health warnings, which may have contributed to the marked decline in smoking prevalence. It is important to understand the evolution of the tobacco epidemic to propose new actions to prevent initiation and encourage cessation among those who started/continued smoking.

Risk of hepatitis A infection following travel.

Travel to endemic areas is one of the most frequently reported risk factors for infection with the hepatitis A virus (HAV). We evaluated the association between HAV infection and travel, by area of destination. We conducted a case-control study on all cases of HAV infection reported to the Italian National Surveillance System for Acute Viral Hepatitis in the period 1996-2000. The study population consisted of 9695 persons with HAV infection (cases) and 2590 with HBV infection (controls). The risk of acquiring HAV was highest for travel to Asia, Africa and Latin America [Odds Ratio = 9.30 (95%CI = 6.71-12.9)]; a three-fold statistically significant excess of risk was found for travel to southern Italy (OR = 3.03) and to the Mediterranean Area and Eastern Europe (OR = 3.15). Travel was implicated in 28% of the cases of HAV infection. When stratifying the analysis by area of residence (northern and central Italy vs southern Italy and the Islands), the above-mentioned risks were confirmed only for those residing in northern and central Italy, with no significant risk for those residing in southern Italy and the Islands. Travel to areas endemic for HAV infection constitutes a considerable risk. Our results highlight the importance of developing health policies for improving environmental and hygienic conditions, as well as the prevention of certain eating habits. Vaccination before travelling to a medium or high endemic area could be a safe and effective means of preventing travel-related HAV infection.
