Cigarette Taxes, Smoking-and Exercise?

Determinants of exercise adherence in sedentary middle-aged and older adults

Regular exercise positively impacts neurocognitive health, particularly in aging individuals. However, low adherence, particularly among older adults, hinders the adoption of exercise routines. While brain plasticity mechanisms largely support the cognitive benefits of exercise, the link between physiological and behavioral factors influencing exercise adherence remains unclear. This study aimed to explore this association in sedentary middle-aged and older adults. Thirty-one participants underwent an evaluation of cortico-motor plasticity using transcranial magnetic stimulation (TMS) to measure changes in motor-evoked potentials following intermittent theta-burst stimulation (iTBS). Health history, cardiorespiratory fitness, and exercise-related behavioral factors were also assessed. The participants engaged in a 2-month supervised aerobic exercise program, attending sessions three times a week for 60 min each, totaling 24 sessions at a moderate-to-vigorous intensity. They were divided into Completers (n = 19), who attended all sessions, and Dropouts (n = 12), who withdrew early. Completers exhibited lower smoking rates, exercise barriers, and resting heart rates compared to Dropouts. For Completers, TMS/iTBS cortico-motor plasticity was associated with better exercise adherence (r = -.53, corrected p = .019). Exploratory hypothesis-generating regression analysis suggested that post-iTBS changes (β = -7.78, p = .013) and self-efficacy (β = -.51, p = .019) may predict exercise adherence (adjusted-R2 = .44). In conclusion, this study highlights the significance of TMS/iTBS cortico-motor plasticity, self-efficacy, and cardiovascular health in exercise adherence. Given the well-established cognitive benefits of exercise, addressing sedentary behavior and enhancing self-efficacy are crucial for promoting adherence and optimizing brain health. Clinicians and researchers should prioritize assessing these variables to improve the effectiveness of exercise programs.

The Economics of Tobacco Regulation: A Comprehensive Review

Tobacco regulation has been a major component of health policy in the developed world since the UK Royal College of Physicians' and the US Surgeon General's reports in the 1960s. Such regulation, which has intensified in the past two decades, includes cigarette taxation, place-based smoking bans in areas ranging from bars and restaurants to workplaces, and regulations designed to make tobacco products less desirable. More recently, the availability of alternative products, most notably e-cigarettes, has increased dramatically, and these products are just starting to be regulated. Despite an extensive body of research on tobacco regulations, there remains substantial debate regarding their effectiveness, and ultimately, their impact on economic welfare. We provide the first comprehensive review of the state of research in the economics of tobacco regulation in two decades.

The effect of tobacco policies on youth physical activity

Our research examines the effects of tobacco policies on teenagers' physical activity. Smoking and physical activity are both strategies for weight management, and exercise may be a way to reduce some of the ill effects of smoking. These different links suggest that cigarette taxes could either increase or decrease physical activity. We explore this relationship using repeated cross-sectional 1991-2017 data from the national and state Youth Risk Behavior Surveillance System (YRBSS), combined with state-level policies and controls. Our smoking participation results confirm past work; cigarette taxes have a negative effect on smoking that has waned in recent years. The estimated effects of cigarette taxes on physical activity echo those of smoking; cigarette taxes decrease physical activity and, like smoking, these effects have waned recently. However, one likely avenue - sports participation - is unaffected. These results suggest that increased cigarette taxes lead to modest declines in teen physical activity, a finding consistent with youth using exercise to compensate for the health effects of smoking.
