Adjunctive non-pharmacological analgesia for invasive medical procedures: a randomised trial

BACKGROUND

Non-pharmacological behavioural adjuncts have been suggested as efficient safe means in reducing discomfort and adverse effects during medical procedures. We tested this assumption for patients undergoing percutaneous vascular and renal procedures in a prospective, randomised, single-centre study.

METHODS

241 patients were randomised to receive intraoperatively standard care (n=79), structured attention (n=80), or self-hypnotic relaxation (n=82). All had access to patient-controlled intravenous analgesia with fentanyl and midazolam. Patients rated their pain and anxiety on 0-10 scales before, every 15 min during and after the procedures.

FINDINGS

Pain increased linearly with procedure time in the standard group (slope 0.09 in pain score/15 min, p<0.0001), and the attention group (slope 0.04/15 min; p=0.0425), but remained flat in the hypnosis group. Anxiety decreased over time in all three groups with slopes of -0.04 (standard), -0.07 (attention), and -0.11 (hypnosis). Drug use in the standard group (1.9 units) was significantly higher than in the attention and hypnosis groups (0.8 and 0.9 units, respectively). One hypnosis patient became haemodynamically unstable compared with ten attention patients (p=0.0041), and 12 standard patients (p=0.0009). Procedure times were significantly shorter in the hypnosis group (61 min) than in the standard group (78 min, p=0.0016) with procedure duration of the attention group in between (67 min).

INTERPRETATION

Structured attention and self-hypnotic relaxation proved beneficial during invasive medical procedures. Hypnosis had more pronounced effects on pain and anxiety reduction, and is superior, in that it also improves haemodynamic stability.

Can words hurt? Patient-provider interactions during invasive procedures

Patients are often prepared for procedural discomforts with descriptions of pain or undesirable experiences. This practice is thought to be compassionate and helpful, but there is little data on the effect of such communicative behavior. This study assesses how such descriptions affect patients' pain and anxiety during medical procedures. The interactions of patients with their healthcare providers during interventional radiological procedures were videotaped during a previously reported 3-arm prospective randomized trial assessing the efficacy of self-hypnotic relaxation. One hundred and fifty-nine videos of the standard care and attention control arms were reviewed. All statements that described painful or undesirable experiences as warning before potentially noxious stimuli or as expression of sympathy afterwards were recorded. Patients' ratings of pain and anxiety on 0-10 numerical scales (0=No Pain, No Anxiety at All and 10=Worst Pain Possible, Terrified) after the painful event and/or sympathizing statement were the basis for this study. Warning the patient in terms of pain or undesirable experiences resulted in greater pain (P<0.05) and greater anxiety (P<0.001) than not doing so. Sympathizing with the patient in such terms after a painful event did not increase reported pain, but resulted in greater anxiety (P<0.05). Contrary to common belief, warning or sympathizing using language that refers to negative experiences may not make patients feel better. This conclusion has implications for the training in medical communication skills and suggests the need for randomized trials testing different patient-practioner interactions.

Beneficial effects of hypnosis and adverse effects of empathic attention during percutaneous tumor treatment: when being nice does not suffice

PURPOSE

To determine how hypnosis and empathic attention during percutaneous tumor treatments affect pain, anxiety, drug use, and adverse events.

MATERIALS AND METHODS

For their tumor embolization or radiofrequency ablation, 201 patients were randomized to receive standard care, empathic attention with defined behaviors displayed by an additional provider, or self-hypnotic relaxation including the defined empathic attention behaviors. All had local anesthesia and access to intravenous medication. Main outcome measures were pain and anxiety assessed every 15 minutes by patient self-report, medication use (with 50 mug fentanyl or 1 mg midazolam counted as one unit), and adverse events, defined as occurrences requiring extra medical attention, including systolic blood pressure fluctuations (> or =50 mm Hg change to >180 mm Hg or <105 mm Hg), vasovagal episodes, cardiac events, and respiratory impairment.

RESULTS

Patients treated with hypnosis experienced significantly less pain and anxiety than those in the standard care and empathy groups at several time intervals and received significantly fewer median drug units (mean, 2.0; interquartile range [IQR], 1-4) than patients in the standard (mean, 3.0; IQR, 1.5-5.0; P = .0147) and empathy groups (mean, 3.50; IQR, 2.0-5.9; P = .0026). Thirty-one of 65 patients (48%) in the empathy group had adverse events, which was significantly more than in the hypnosis group (eight of 66; 12%; P = .0001) and standard care group (18 of 70; 26%; P = .0118).

CONCLUSIONS

Procedural hypnosis including empathic attention reduces pain, anxiety, and medication use. Conversely, empathic approaches without hypnosis that provide an external focus of attention and do not enhance patients' self-coping can result in more adverse events. These findings should have major implications in the education of procedural personnel.

Taste damage (otitis media, tonsillectomy and head and neck cancer), oral sensations and BMI

Otitis media and tonsillectomy are associated with enhanced palatability of energy dense foods and with weight gain. Otitis media can damage the chorda tympani nerve (CN VII); tonsillectomy and head and neck radiation treatment can damage the glossopharyngeal nerve (CN IX). Both of these nerves function prominently in taste sensation. The present study utilizes these sources of damage to study central interactions among the nerves that mediate oral sensations. Mild damage restricted to one of these nerves can actually intensify sensations evoked from undamaged nerves (i.e., whole-mouth taste, oral tactile sensations evoked by fats and irritants). These intensifications may result from disruption of central inhibitory taste circuits, as taste damage appears to disinhibit other oral sensory nerves. In addition, mild damage restricted to one taste nerve can intensify odors perceived from foods in the mouth during chewing and swallowing (i.e., retronasal olfaction); this may be a secondary consequence of the intensification of whole-mouth taste. Damage to both nerves leads to widespread oral sensory loss. At present, the link between sensory alterations and weight gain has not been established for adults (e.g., does increased fat preference occur in individuals with oral sensory intensifications, those with losses, or both?). Finally, pain in non-oral locations is also related to taste loss. When participants rated "the most intense pain of any kind they had ever experienced," those with the greatest taste loss gave the highest ratings. These effects suggest that taste loss significantly influences long-term health outcomes.

Predictors of short-term and long-term memory of sensory and affective dimensions of pain

The purpose of this investigation was to establish predictors of the dimensions of pain intensity and pain unpleasantness recalled at 1 week and 18 months after an invasive therapeutic procedure, root canal therapy (RCT). Pretreatment measures of mood state and RCT-related expectations of sensory and affective dimensions of pain by using a visual analog scale (VAS) format were obtained. VAS measures of experienced pain intensity and unpleasantness were obtained immediately after treatment. Patients[apos ] memory of their RCT-related pain intensity and unpleasantness was assessed by phone call. Regression analysis showed that after controlling for age, experienced pain intensity predicts 1-week memory of pain intensity (adjusted R(2) [equals].34, P [lt ].01), whereas patients[apos ] pretreatment affective state predicts the memory of pain intensity at 18 months (adjusted R(2) [equals].24, P [lt ].01) and the memory of pain unpleasantness at 1 week (adjusted R(2) [equals].40, P [lt ].01) and 18 months (adjusted R(2) [equals].62, P [lt ].01). These findings point to the contribution of preexisting affective state to the sensory and affective dimensions of pain recollection and illustrate the importance of anxiety management for minimizing patient[apos ]s long-term recollection of the aversiveness of outpatient medical and dental procedures.

Pain related recall predicts future pain report

It is frequently necessary for patients to undergo multiple painful medical interventions as part of their diagnosis and care. Predictors of future pain report have yet to be established although initial pain level, affect, and memory of the procedure are often implicated. The purpose of this research was to establish a predictive model of future pain reporting using a standardized experimental pain stimulus. Forty-three healthy subjects completed an initial forehead cold pressor task (Session 1) and an identical task nine months later (Session 2). Subjects also provided retrospective pain evaluations six months after Session 1. Hierarchical regression was used to identify predictors of Session 2 maximum pain intensity. Fifty-six percent of the total variance (p < .01) was accounted when Session 1 maximum pain intensity, Session 1 negative affect, and remembered maximum pain intensity were loaded together in the model. Only 1% of the variance was uniquely accounted by Session 1 maximum pain intensity (p = .38) while remembered maximum pain intensity uniquely accounted for 25% of the variance (p < or = .01) and Session 1 negative affect uniquely accounted for 17% of the variance (p < or = .01). An additional 13% of the variance was shared between Session 1 maximum pain intensity and remembered maximum pain intensity. The level of remembered Session 1 pain was significantly exaggerated from the initial pain report (p < or = .05) but not significantly different from the level of pain reported at Session 2. These findings provide strong evidence for a post-pain modulation phenomenon in which cognitive processes influence both pain recall and future pain reporting.

Exploration of the common bile duct--the relevance of the clinical picture and the importance of peroperative cholangiography

A series of 500 cholecystectomies performed over a 7-year period was reviewed retrospectively. The reliability of preoperative clinical features such as jaundice and pancreatitis was assessed in determining the presence of choledocholithiasis, and was found to be of limited value. Investigations such as intravenous cholangiography and liver function tests were found also to be inaccurate in the detection of common duct stones as was the appearance of the duct at operation. The usefulness of the peroperative cholangiogram in the detection of common duct stones that would otherwise have been overlooked is emphasized. Common duct stones would have remained undetected in 25 per cent of patients with choledocholithiasis. Despite the use of routine peroperative cholangiography common duct stones were overlooked in 11.25 per cent of patients who underwent exploration.

Memory for Stress-Associated acute pain

Negative emotions (eg, tension, anxiety, fear, anger) influence acute pain recall. Given reliance on patient-provided pain reports across the care continuum, an understanding of factors that modulate pain memory processing become important to patients, clinicians, and health care organizations. The purpose of this study was to investigate the influence of negative emotions on the prediction of 6-month pain recall by using an experimental stress manipulation (speech task) + pain (forehead cold pressor) versus nonstress control + pain crossover design (n = 68). Results showed that (1) negative emotions were greater in the stress session than the nonstress session, and experienced pain levels did not differ by condition or sex; (2) the level negative emotions at the time of the pain stimuli mediated the ability of experienced pain to predict pain recall; and (3) women recalled more stress session pain than men, and nonstress pain was accurately recalled. Integrating these findings with those of others, we present a model of acute pain memory recall in which negative emotions influence pain memory processing wherein the level of experienced pain predicts short-term recall and affective state at the time of the experience becomes a powerful predictor for the long-term recall of experienced pain level.

PERSPECTIVE

After 6 months the level of recalled experimental pain delivered within a stressful context becomes exaggerated. Negative emotions at the time of the painful stimuli and at recall influenced the prediction of the level of recalled pain. Emotional arousal may influence how memory for pain is encoded, processed, and retrieved.

Racial differences in oral and pharyngeal cancer treatment and survival in Florida

OBJECTIVE

This study examined racial differences in treatment and survival for blacks and whites in Florida diagnosed with oral or pharyngeal cancer.

METHODS

Data for 21,481 malignancies of the oral cavity or pharynx diagnosed from 1988 to 1998 were derived from the Florida Cancer Data System. Type of cancer treatment was compared by race, stratified by anatomic site and summary stage at diagnosis. Kaplan-Meier survival curves were used to compare survival rates and Cox regression models were used to estimate hazard ratios for race. Covariates included age, sex, census tract income, and treatment.

RESULTS

Stratifying by tumor site and stage, blacks consistently had poorer survival rates than whites. Across tumor stages, blacks with oral cavity cancer were consistently more likely than whites to have received only radiotherapy and less likely to have received cancer-directed surgery. Trends were similar for pharyngeal cancer, although statistically significant only for regional stages. Across site and stage, blacks consistently had elevated hazard ratios (range: 1.20-1.53) relative to whites.

CONCLUSIONS

In Florida, there were racial differences in patient treatment for oral or pharyngeal cancer. Blacks had lower survival rates than whites, but differences in treatment did not entirely account for racial disparities in survival.

Effects of relaxation and stress on the capsaicin-induced local inflammatory response

OBJECTIVE

Although stress is known to modulate the inflammatory response, there has been little experimental examination of the effects of stress and stress reduction on inflammation in humans. In particular, the effects of stress and relaxation on neurogenic inflammation have been minimally studied. This study examines the effects of three experimental manipulations: mental stress, relaxation, and control on the local inflammatory response evoked by the intradermal injection of capsaicin, the active ingredient in chili peppers.

METHODS

Fifty subjects (28 men and 22 women) were pretrained in relaxation using an imagery-based relaxation tape and then randomized to experimental condition. Subjects participated in an evening reactivity session including 20 minutes of a stress (Stroop test), relaxation (tape), or control (video) manipulation, followed by a capsaicin injection in the forearm. Digitized flare measurements were taken for 1 hour postcapsaicin, and measurements of cardiovascular variables, cortisol, adrenocorticotrophic hormone, and norepinephrine were taken at regular intervals.

RESULTS

The size of the maximum capsaicin-induced flare was significantly smaller in the relaxation condition than in the stress or control conditions, which did not differ from each other. Increases in norepinephrine, heart rate, and systolic blood pressure during the experimental task, but not after capsaicin, significantly predicted size of maximum flare and total area under the curve of flare measurements.

CONCLUSIONS

These findings suggest that stress reduction may affect local inflammatory processes. Results are consistent with sympathetic modulation of the effects of relaxation on the flare response.

A survey of barriers to screening for oral cancer among rural Black Americans

OBJECTIVE

Research documents a disparity between Black and White Americans in mortality for oral cancer that appears to result in part from behaviors such as lower oral cancer screening among Black Americans. We examined barriers to oral cancer screening among Black Americans.

METHODS

We surveyed Black Americans (N = 366) living in rural Florida to identify barriers to getting screened for oral cancer.

RESULTS

Low knowledge/social attention, lack of resources, and fear/defensive avoidance predicted screening intentions, with lack of resources emerging as the largest barrier. Participants also reported that a recommendation from their provider was most likely to increase screening intentions, whereas encountering financial barriers was most likely to decrease screening intentions.

CONCLUSIONS

Low knowledge/social attention, lack of resources, and fear/defensive avoidance emerged as independent barriers to oral cancer screening, with the latter two barriers accounting for the most variance in intentions to get screened.

Thyroid hormones and selenium status in breast cancer

Within a case-control study of postmenopausal breast cancer patients (n = 99) and matched healthy controls (n = 105), thyroid hormone levels were compared and correlated with toenail selenium concentrations. Plasma triiodothyronine (T3) was significantly lower in cases (1.4 +/- 0.4 nmol/l) than in controls (1.6 +/- 0.4 nmol/l), and a strong inverse relationship with breast cancer was observed with an odds ratio of 0.17 (95% CI = 0.08-0.36) in the highest compared with the lowest tertile of T3. Plasma thyroxine and thyroid-stimulating hormone concentrations were similar between cases and controls. Plasma T3 concentration was positively associated with toenail selenium in cases (age-adjusted regression coefficient = 0.049) and controls (age-adjusted regression coefficient = 0.036). Toenail selenium concentrations tended to be lower in cases than in controls, but the differences did not reach statistical significance. Although the disease process per se may explain the lower plasma T3 concentrations, it is also possible, inasmuch as these patients were in early-stage breast cancer, that selenium status may be influencing T3 levels via changes in the activity of the selenoenzyme type 1 iodothyronine deiodinase.

Emotional and sensory focus as mediators of dental pain among patients differing in desired and felt dental control

Giving patients instructions to focus on sensory (vs. emotional) stimuli during a root canal procedure significantly reduced self-reported pain, but only among patients who were classified as having strong desire for control and low felt control in dental situations. Among patients with low felt control and low desire for control, sensory-focus instructions produced greater pain reports than did emotion-focus instructions. Finally, high desire-low felt patients reported higher levels of expected pain before treatment than did other patient subgroups. These data suggested limiting conditions for H. Leventhal's (1982) theory of emotion and supported the idea that desire for control might moderate the effects of perceived control.

Desire for control, felt control, and stress inoculation training during dental treatment

Coping style research has typically assessed subjects' desire for a coping resource, but ignored whether subjects possess that resource. In this study 110 dental patients were categorized as to their desire for and feelings of control and were randomly assigned, just prior to dental treatment, to a 20-minute Stress Inoculation Training (SIT) session or a Filler condition. SIT significantly reduced pain and increased control only for patients who initially reported a high desire for control coupled with low perceived control. This finding supports the view that the discrepancy between high desire for control and low perceived control plays a causal role in the elevated distress and pain initially reported by patients with such control perceptions. These data indicate that consideration of patients' perceived coping resources as well as their coping preferences adds to our ability to predict reactions to stress reduction manipulations.

Effects of stress and relaxation on capsaicin-induced pain

A sizable body of research has been devoted to understanding the relationship between pain sensitivity and the psychological state of the individual. Considerable disagreement as to the direction of the association still exists. This study examines the effects of 2 experimental manipulations, cognitive/emotional stress and relaxation, on capsaicin-induced pain. Subjects were pretrained in relaxation and then randomized to experimental stress produced by a 20-minute Stroop test, relaxation (tape), or a control condition (neutral video), followed by a capsaicin injection in the forearm. Cardiovascular measures were taken at regular intervals, and cortisol, norepinephrine (NE), and self-reports of arousal (relaxation index) were taken immediately before and after the experimental task. The manipulation significantly interacted with sex to predict capsaicin-induced maximum pain. Women in the stress condition reported greater pain than both men in the stress condition and women in the relaxation condition. Pain was correlated negatively with task-induced changes in NE and cortisol and positively with self-reported arousal (decreased relaxation). However, separate analyses showed that some physiologic indexes of heightened arousal (increased blood pressure and NE) predicted lower pain only in men, whereas subjective increases in arousal predicted higher pain only in women. Multiple hierarchical regression analyses confirmed that physiologic and self-reported arousal predicted pain independently and in opposite directions, and a model including both accounted for 56% of the overall variance. These findings suggest that a unidimensional model of arousal may be insufficient to explain the effects of stress on pain and that these effects operate differently in men and women.

Effects of acute stress, relaxation, and a neurogenic inflammatory stimulus on interleukin-6 in humans

Effects of three experimental manipulations: mental stress, relaxation, and a nociceptive inflammatory stimulus, capsaicin, on levels of interleukin-6 (IL-6) were examined. Fifty subjects were pre-trained in relaxation and then randomized to a stress (Stroop test), relaxation (tape), or control (video) manipulation. Subjects participated in an evening reactivity session including 20 min of stress, relaxation, or control followed by a capsaicin injection in the forearm. Cardiovascular variables and levels of IL-6 were measured before and after the manipulation, and at regular intervals up to 60 min post-capsaicin. Group assignment did not differentially affect change in IL-6 over time, either before or after capsaicin. Small but significant increases in IL-6 were seen at 60 min post-capsaicin. These findings suggest that an acute stress manipulation does not modulate IL-6 within this time frame. Although IL-6 did increase following a neurogenic inflammatory stimulus, it did so subsequent to the maximum flare, suggesting that flare mechanisms are independent of IL-6.

Identical and Nonidentical Twins: Risk and Factors Involved in Development of Islet Autoimmunity and Type 1 Diabetes

OBJECTIVE

There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings.

RESEARCH DESIGN AND METHODS

Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years.

RESULTS

At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects.

CONCLUSIONS

Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Can we assess quality of life in patients with head and neck cancer? A preliminary report from the American Academy of Maxillofacial Prosthetics

Survival statistics alone may no longer be valid when used as evidence of effective outcomes. Patient satisfaction is an end point that needs further evaluation and should be included in the outcomes assessment. A 133-item questionnaire has been designed by a special committee of the American Academy of Maxillofacial Prosthetics (AAMP) to assess the quality of life of patients with head and neck cancer impacting the orofacial region. This survey will be distributed to the entire population of 7 geographically dispersed treatment centers in the United States for a 2-year period. Patients will be stratified into several subgroups, including radiation/nonradiation, maxillary/mandibular, and surgical reconstruction/prostheses. Separate analyses will be conducted for each subgroup, and comparisons will be made within subgroups to test the sensitivity of the questionnaire to a known difference. A revised version of the AAMP questionnaire, limited to 50 items of interest to patients, will be validated against 2 established head and neck cancer questionnaires. This article provides background on previous quality-of-life studies and reviews the need for and aims of the AAMP assessment instrument.

Effects of analgesics on orthodontic pain

INTRODUCTION

Our objective was too assess the effectiveness of 3 analgesics (ibuprofen, naproxen sodium, and acetaminophen) and a placebo administered before and after the placement of separators in reducing the severity of postseparator placement pain. We also examined the impact of treatment on chewing efficiency at 24 hours after separator placement.

METHODS

Twenty-four subjects participated in the study. Each subject received 3 of 4 treatments: ibuprofen, naproxen sodium, acetaminophen, or placebo in random order at monthly intervals. The dosing times were 1 hour before separator placement and 3 and 7 hours after separator placement. Before placement, the subjects completed a masticatory efficiency test and a visual analog scale (VAS) for expected pain and pain experienced. A VAS pain diary was kept for 24 hours. Subjects returned to the clinic after 1 week for separator removal.

RESULTS

VAS pain summary scores after separator placement were significantly affected by the administration of ibuprofen (P = 0.0298) and the time after separator placement (P <0.0001). Administering ibuprofen before and after separator placement significantly reduced pain compared with the placebo. The analgesic effects diminished by day 2, resulting in peak pain levels and decreased chewing efficiency. The expected pain after separator placement also played a role in experienced pain; subjects expecting more pain experienced more pain.

CONCLUSIONS

Ibuprofen was superior to the placebo in relieving postseparator pain as measured by the VAS pain summary scores, whereas acetaminophen and naproxen sodium did not significantly differ from the placebo.

Barriers to oral cancer screening: a focus group study of rural Black American adults

OBJECTIVE

Mortality from mouth and throat cancer (MTC) is higher among Black Americans than White Americans partially because of late stage detection through screening. The disparity in mortality is particularly problematic among Black Americans living in rural areas who have limited access to preventative resources. Our study explored barriers to screening for MTC among Black Americans.

METHODS

We conducted nine focus groups among rural Black Americans age 40 years and older (N = 80).

RESULTS

Content coding of the transcripts of the focus groups revealed three primary barriers to screening. Lack of knowledge (e.g., not knowing about MTC and not knowing MTC symptoms) accounted for 31.8% of all barriers mentioned, lack of resources (e.g., lack of money and health insurance) accounted for 25.0% of all barriers mentioned, and fear (e.g., fear of screening and diagnosis) accounted for 22.9% of all barriers mentioned.

CONCLUSIONS

We placed these barriers within the Theory of Planned Behavior and conclude that interventions aimed at increasing MTC screening among rural Black Americans should first focus on changing people's attitudes about screening by increasing knowledge about MTC and reducing fear.

The burden of chronic diseases in a rural North Florida sample

BACKGROUND

The degree of health disparities present in rural communities is of growing concern and is considered "urgent" since rural residents lag behind their urban counterparts in health status. Understanding the prevalence and type of chronic diseases in rural communities is often difficult since Americans living in rural areas are reportedly less likely to have access to quality health care, although there are some exceptions. Data suggest that rural residents are more likely to engage in higher levels of behavioral and health risk-taking than urban residents, and newer evidence suggests that there are differences in health risk behavior within rural subgroups. The objective of this report is to characterize the prevalence of four major and costly chronic diseases (diabetes, cardiovascular disease, cancer, and arthritis) and putative risk factors including depressive symptoms within an understudied rural region of the United States. These four chronic conditions remain among the most common and preventable of health problems across the United States.

METHODS

Using survey data (N = 2526), logistic regression models were used to assess the association of the outcome and risk factors adjusting for age, gender, and race.

RESULTS

Key findings are (1) Lower financial security was associated with higher prevalence of cardiovascular disease, arthritis, and diabetes, but not cancer. (2) Higher levels of depressive symptoms were associated with higher prevalence of cardiovascular disease, arthritis, and diabetes. (3) Former or current smoking was associated with higher prevalence of cardiovascular disease and cancer. (4) Blacks reported higher prevalence of diabetes than Whites; Black women were more likely to report diabetes than all other groups; prevalence of diabetes was greater among women with lower education than among women with higher education. (5) Overall, the prevalence of diabetes and arthritis was higher than that reported by Florida and national data.

CONCLUSIONS

The findings presented in this paper are derived from one of only a few studies examining patterns of chronic disease among residents of both a rural and lower income geographic region. Overall, the prevalence of these conditions compared to the state and nation as a whole is elevated and calls for increased attention and tailored public health interventions.

Physical activity behavior, barriers to activity, and opinions about a smartphone-based physical activity intervention among rural residents

BACKGROUND

Rural Americans engage in less physical activity (PA) and experience higher rates of consequent health problems (i.e., obesity, cardiovascular disease) than urban Americans. Although geographic barriers have historically made this population hard to reach, rural individuals are increasingly gaining access to smartphones. Thus, the purpose of this study was to evaluate PA behavior and barriers to PA among rural residents and to gauge their receptiveness to a smartphone-based PA intervention that is currently in the development stage.

MATERIALS AND METHODS

Rural Floridian adults (n=113), 18 years of age and older, completed surveys to assess PA behavior, PA barriers, and opinions about an intervention to increase PA. Specifically, they were asked to imagine a program that would require them to do PA with their mobile phones and whether they viewed intended aspects of the program as helpful. The present work is therefore formative research that sought to determine the feasibility and acceptability of a smartphone-based intervention among rural residents. RESULTS of the survey will inform the development of a tailored, smartphone-based PA intervention.

RESULTS

The 37.2% of participants with low PA levels (<600 metabolic equivalent [MET]-min per week) were more likely to report personal and environmental barriers to PA than the 47.8% of participants with moderate PA levels (≥600 MET-min per week). More barriers were reported among participants who self-reported as white and among participants of older age, lower education level, and lower socioeconomic status. Additionally, 75.9% of participants reported features of the intervention as at least somewhat helpful.

CONCLUSIONS

The growing ubiquity of smartphones among rural residents, combined with participants' positive response to the program description, supports the acceptability of a smartphone-based PA intervention for rural communities. Given the participants' receptiveness, future research should evaluate the efficacy of smartphone-delivered health behavior interventions among this population.
