Abstract In this study, we evaluated cardiovascular. neuroendocrine, and psychological adjustment to repeated presentations of a public speaking mental arithmetic task. Brief versions tasks have been used widely in previous reactivity studies, growing attention more socially salient has led the increased use tasks. However, psychophysiological during extended exposure these not delineated. present 52 healthy men worked on three 8‐min measure design. Both produced substantial cardiovascular,...
The Food and Drug Administration can set standards that reduce the nicotine content of cigarettes. We conducted a double-blind, parallel, randomized clinical trial between June 2013 July 2014 at 10 sites. Eligibility criteria included an age 18 years or older, smoking five more cigarettes per day, no current interest in quitting smoking. Participants were randomly assigned to smoke for 6 weeks either their usual brand one six types investigational cigarettes, provided free. had ranging from...
Recent advances in mobile health have produced several new models for inferring stress from wearable sensors. But, the lack of a gold standard is major hurdle making clinical use continuous measurements derived In this paper, we present model (called cStress) that has been carefully developed with attention to every step computational modeling including data collection, screening, cleaning, filtering, feature computation, normalization, and training. More importantly, cStress was trained...
The effect of psychosocial stress on health has been a central focus area public research. However, progress limited due to lack wearable sensors that can provide robust measures in the field. In this paper, we present wireless sensor suite called AutoSense collects and processes cardiovascular, respiratory, thermoregularity measurements inform about general state test subjects their natural environment. overcomes several challenges design systems for use First, it is unobtrusively because...
The optimal temporal approach for reducing nicotine to minimally or nonaddictive levels in all cigarettes sold the United States has not been determined. To determine effects of immediate vs gradual reduction content very low and as compared with usual level on biomarkers toxicant exposure. A double-blind, randomized, parallel-design study 2 weeks baseline smoking 20 intervention was conducted at 10 US sites. volunteer sample daily smokers no intention quit within 30 days recruited between...
Recent researches have demonstrated the feasibility of detecting smoking from wearable sensors, but their performance on real-life lapse detection is unknown. In this paper, we propose a new model and evaluate its 61 newly abstinent smokers for first lapse. We use two sensors --- breathing pattern respiration arm movements 6-axis inertial worn wrists. 10-fold cross-validation 40 hours training data 6 daily smokers, our achieves recall rate 96.9%, false positive 1.1%. When applied to 3 days...
Management of daily stress can be greatly improved by delivering sensor-triggered just-in-time interventions (JITIs) on mobile devices. The success such JITIs critically depends being able to mine the time series noisy sensor data find most opportune moments. In this paper, we propose a pattern mining method detect significant episodes in discontinuous and rapidly varying data. We apply our model 4 weeks physiological, GPS, activity collected from 38 users their natural environment discover...
Research has demonstrated that women report more pain than men, and clinical observations suggest attenuated adrenocortical activity is associated with high sensitivity. The extent to which cortisol concentrations hemodynamics contribute gender differences in sensitivity not been investigated. Thirty-four 31 men performed the hand cold pressor test (CPT). Participants rated their every 15 s during a 90-s CPT post-CPT recovery period reported using McGill Pain Questionnaire (MPQ). Salivary...
Catastrophizing is reliably associated with increased reports of clinical and experimental pain. To test the hypothesis that catastrophizing may heighten pain experience by increasing nociceptive transmission through spinal gating mechanisms, present study examined as a predictor ratings flexion reflex (NFR) thresholds in 88 young adult men (n=47) women (n=41). The NFR threshold was defined intensity electrocutaneous sural nerve stimulation required to elicit withdrawal response from biceps...
Objective: Caffeine increases cortisol secretion in people at rest or undergoing mental stress. It is not known whether tolerance develops this response with daily intake of caffeine the diet. We therefore tested to challenge after controlled levels intake. Methods: Men (N = 48) and women completed a double-blind, crossover trial conducted over 4 weeks. On each week, subjects abstained for 5 days from dietary instead took capsules totaling 0 mg, 300 600 mg/day 3 divided doses. day 6, they...
The current study examined whether prequit trait negative mood and smoking motives have different predictive patterns of relapse in men women. Thirty-three female (mean age±SEM: 34.9±2.5) 38 male 37.1±2.3) smokers interested cessation completed forms on history, (i.e., depression, anxiety, anger), stress, motives. Participants also provided samples for measurement cotinine carbon monoxide. Then, they set a quit date were required to abstain from at least 24 hours. followed up 12 months...
There are compelling theoretical and empirical reasons that link household food insecurity to mental distress in the setting where both problems common. However, little is known about their association during pregnancy Ethiopia. A cross-sectional study was conducted examine of with pregnancy. Six hundred forty-two pregnant women were recruited from 11 health centers one hospital. Probability proportional size (PPS) consecutive sampling techniques employed recruit subjects until desired...
Reduced nicotine content (RNC) cigarettes have led to smoking fewer cigarettes, withdrawal relief, and facilitation of cessation. The aim this study is examine the effects RNC with without patch alone on behavior, toxicant exposure, discomfort, as an exploratory analysis, long-term abstinence.This involved a randomized, parallel arm design six weeks of: (i) 0.05-0.09 mg yield (N = 79); (ii) 21 80), or (iii) 76); all groups received additional behavioral treatment follow-ups up...
