BackgroundIn 2022, 3.7% of U.S. adults currently smoked cigars. This study assesses cigar-smoking-attributable fractions in U.S. healthcare expenditures and associated annual healthcare expenditures overall and by payer, including publicly funded healthcare programs.
MethodsData were obtained from the 2000, 2005, 2010, and 2015–2017 National Health Interview Survey linked with corresponding panels from the Medical Expenditure Panel Survey data through 2018. The final sample (n = 53,733) was restricted to adults aged 25 + . Estimates from four-part models and data from the Personal Health Care component of the 2001–2018 National Health Expenditures Accounts were combined to estimate fractions of and annual healthcare expenditures attributable to cigar smoking. All models controlled for sociodemographic characteristics and health-related behaviors.
ResultsDuring 2001–2018, an estimated 1.8% (95% CI = 0.9%–3.4%) or $29.7 billion annually of U.S. healthcare expenditures could be attributed to cigar smoking. Most of this was funded by other third-party health insurance programs, a mix of private and public payers (e.g., Department of Veterans Affairs).
ConclusionsCigar smoking creates a preventable financial burden on the U.S. healthcare system. Health consequences associated with cigar smoking may remain after successful quitting. The findings underscore the importance of preventing initiation of cigar smoking and providing evidence-based cessation methods to reduce the health and economic burden of cigar smoking.
Non-communicable diseases (NCDs), such as diabetes, cardiovascular diseases and cancer, are major global public health concerns. Diet quality—particularly the consumption of ultra-processed foods—has been associated with increased risk of NCDs. Traditional cohort studies are often expensive and logistically complex. The NutriNet-Brasil cohort leverages a web-based approach, offering a cost-effective and practical solution for comprehensive data collection and long-term follow-up.
Recruitments began in January 2020 through mass media, social media campaigns and collaborations with health organisations. Eligible participants are adults (aged ≥18 years) living in Brazil with internet access. Participants complete self-administered online questionnaires covering dietary intake, health status and other health determinants. Dietary assessment is based on the Nova classification system, which categorises foods by their level of processing.
Over 88 000 participants have completed the initial questionnaire. The cohort is predominantly women (79.9%) and highly educated (67.9% had completed higher education). The web-based design enabled the development and application of innovative dietary assessment tools, including the Nova24h and the Nova24hScreener, specifically designed to evaluate food processing levels. These tools have shown good performance in capturing dietary patterns and are central to the cohort’s aim. The online platform facilitates efficient recruitment, data collection and participant retention.
NutriNet-Brasil is pioneering the development of web-based cohort methodologies and instruments tailored to food processing research. Future work includes leveraging collaborations with national and international research centres to conduct multidisciplinary analyses and inform public health policies.
