Price Elasticity of cigarette smoking demand in the Philippines after the 2012 Sin Tax Reform Act.
The Philippine tobacco excise tax reform law passed in 2012 drastically increased cigarette prices which were historically low. A pack of 20 cigarettes costing nine cents (US Dollar) or less was taxed five cents in 2011. When the reform took effect in 2013, each pack was taxed 24 cents which is almost five times the 2011 rate. ⋯ Results confirm that cigarette demand is inelastic, given that total cigarette price elasticity of demand ranges from -0.56 to -1.10 which means that for every 10% price increase, total cigarette demand declines by 5.6% to 11.0%. This study also provides total price elasticities for different subpopulations. Future studies can use these elasticity estimates to forecast smoking prevalence and provide policy recommendations.

Smoking and use of electronic cigarettes (vaping) in relation to preterm birth and small-for-gestational-age in a 2016 U.S. national sample.
Women who smoke may be motivated to switch to vaping (use electronic cigarettes, e-cigs) around pregnancy in seeking to alleviate known hazards of smoking. E-cigs typically contain nicotine but either eliminates or greatly reduces exposure to the combustion products of tobacco. We studied a U. ⋯ Late-pregnancy dual-users also had similar risk of preterm birth as non-users (aOR 1.3, 95% CI 0.8-2.3). However, late-pregnancy sole vapers and dual-users had increased risk of SGA compared to non-users (aOR 2.4, 95% CI 1.0-5.7 for sole vapers, and aOR 2.3 95% CI 1.3-4.1 for dual-users). These findings suggest that vapers during pregnancy had similar risk of preterm as non-users but still had elevated risk for restricted fetal growth.

Incidence and public health burden of sunburn among beachgoers in the United States.
The beach environment creates many barriers to effective sun protection, putting beachgoers at risk for sunburn, a well-established risk factor for skin cancer. Our objective was to estimate incidence of sunburn among beachgoers and evaluate the relationship between sunburn incidence and sun-protective behaviors. A secondary analysis, of prospective cohorts at 12 locations within the U. ⋯ For those spending ≥5 h in the sun, the use of multiple types of sun protection reduced odds of sunburn by 55% relative to those who used no sun protection (Odds Ratio = 0.45 (95% Confidence Interval:0.27-0.77)) after adjusting for skin type, age, and race. Acute health effects of sunburn tend to be mild and self-limiting, but potential long-term health consequences are more serious and costly. Efforts to encourage and support proper sun-protective behaviors, and increase access to shade, protective clothing, and sunscreen, can help prevent sunburn and reduce skin cancer risk among beachgoers.

Early life weight patterns and risk of obesity at 5 years: A population-based cohort study.
Childhood obesity is a major public health problem in industrialized countries. The aim of this study was to estimate the risk of obesity at age 5 based on BMI categories at age 3 and changes in BMI z-score from birth to 3 years of age. In this population-based study BMI data of 5173 children were collected at ages 3 and 5 and were linked to information relative to birth weight. ⋯ The risk of obesity for children born large for gestational age was 6.5%, while it was 18.6% for children overweight at age 3 and 62% for children who were obese at 3. An increase in BMI z-score from birth to 3 years increases the risk of obesity at age 5 (OR for increase of one standard deviation 2.8%; 95% CI: 2.46-3.20), but adjusting for BMI z-score at age 3, the effect of trajectory disappears (OR 1.08 95% CI: 0.9-1.29). In other words, if one targeted early preventive interventions to 3-year-olds affected by overweight/obesity (only 9.8% of the study cohort), one could possibly address 71% of children potentially affected by obesity at age 5.

A vulnerability assessment for the HCV infections associated with injection drug use.
After the 2014-2015 HIV outbreak in Scott County, Indiana, United States Centers for Disease Control and Prevention (CDC) conducted a nationwide analysis to identify vulnerable counties to an outbreak of Hepatitis C Virus (HCV)/Human Immunodeficiency Virus (HIV) and prevent such an outbreak in the future. We developed a jurisdiction-level vulnerability assessment for HCV infections associated with injection drug use (IDU) in Utah. We used three years of data (2015-2017) from 15 data sources to construct a regression model to identify significant indicators of IDU. ⋯ Moreover, we should consider evaluating whether the improvement of HCV screening has an impact on controlling HCV outbreaks. The analysis informs Utah's agencies and healthcare officials to target resources and interventions to prevent IDU-related HCV outbreaks. Our results inform policymakers at the national level on possible indicators of HCV outbreaks as well.
