RESUMO

INTRODUCTION: Flavored waterpipe (WP) tobacco is the main type of tobacco used by young WP smokers, and a major factor attracting youth to smoke. However, evidence regarding the effect of limiting flavor on WP smokers' experience continues to be lacking. This study aims at evaluating the effect of flavor restriction on WP smokers' toxicant exposure, smoking topography, subjective experiences and harm perception. METHODS: Thirty-two WP smokers completed two, 45-minute ad libitum smoking sessions (preferred flavor vs non-flavored tobacco) in a crossover design pilot study. Plasma nicotine concentration and exhaled carbon monoxide (eCO) were measured before and after each smoking session. Puff topography was recorded throughout the smoking session. Participants completed survey questionnaires assessing subjective smoking experiences and harm perception. RESULTS: Significant differences were observed in plasma nicotine concentration between the two WP tobacco conditions, with a higher increase in plasma nicotine concentration following the flavored tobacco session. There were no significant differences between the two WP tobacco conditions for eCO and smoking topography measures. Compared with the non-flavored WP tobacco, we documented enhanced subjective smoking measures of satisfaction, calmness, taste, puff liking and enjoyment following the preferred flavored WP tobacco session. Cigarette harm perception was significantly higher among participants after smoking their preferred flavor compared with non-flavored WP tobacco. CONCLUSIONS: Limiting tobacco flavor has a substantial effect on WP smokers' nicotine exposure, subjective experience and harm perception. Therefore, eliminating or restricting WP flavors could be an essential element of comprehensive tobacco control policies to reduce the appeal of WP tobacco products for youth. IMPLICATIONS: This study highlights the important role of flavor in shaping WP smokers' experiences and exposures and the potential impact that regulating flavored WP tobacco may have on curbing WP use among youth in the US. Such regulations may reduce the appeal and the interest in WP smoking initiation and continued use.

RESUMO

INTRODUCTION: Waterpipe smoking continues to pose significant challenges to tobacco control efforts and many adolescent waterpipe smokers experience symptoms of nicotine dependence (ND). This study examined the predictors of progression of ND symptoms in adolescent waterpipe smokers. METHODS: We assembled a cohort of Lebanese adolescents enrolled in eighth and ninth grades at baseline, and surveyed them every 6 months over the next 24 months. Progression of ND symptoms was defined as an increase over time in the number of items endorsed on the Hooked on Nicotine Checklist. Predictors included individual (eg, psychological factors, attitudes towards waterpipe, school performance, physical activity) and socioenvironmental (eg, smoking among parents, siblings and close friends; the café environment) attributes. RESULTS: Among 264 adolescent waterpipe smokers (baseline mean age=14.6 years, 50.4% females), 105 (39.7%) progressed on ND symptoms during follow-up. Predictors of progression were higher baseline stress (OR 1.11, 95% CI 1.03 to 1.19) and higher self-esteem (OR 1.14, 95% CI 1.05 to 1.24). Reporting difficulty refraining from smoking waterpipe while in a restaurant was the strongest predictor of progression (OR 4.04, 95% CI 1.44 to 11.34). Having a mother with ≥12 years of education protected against progression of ND (OR 0.46, 95% CI 0.21 to 0.99). CONCLUSIONS: A significant proportion of adolescent waterpipe smokers progressed on ND. Venue-based policies such as limiting youth access to waterpipe cafés are warranted.

RESUMO

Background: Contemporary data on the prevalence of e-cigarette use in the United States are limited. Objective: To report the prevalence and distribution of current e-cigarette use among U.S. adults in 2016. Design: Cross-sectional. Setting: Behavioral Risk Factor Surveillance System, 2016. Participants: Adults aged 18 years and older. Measurements: Prevalence of current e-cigarette use by sociodemographic groups, comorbid medical conditions, and states of residence. Results: Of participants with information on e-cigarette use (n = 466 842), 15 240 were current e-cigarette users, representing a prevalence of 4.5%, which corresponds to 10.8 million adult e-cigarette users in the United States. Of the e-cigarette users, 15% were never-cigarette smokers. The prevalence of current e-cigarette use was highest among persons aged 18 to 24 years (9.2% [95% CI, 8.6% to 9.8%]), translating to approximately 2.8 million users in this age range. More than half the current e-cigarette users (51.2%) were younger than 35 years. In addition, the age-standardized prevalence of e-cigarette use was high among men; lesbian, gay, bisexual, and transgender (LGBT) persons; current combustible cigarette smokers; and those with chronic health conditions. The prevalence of e-cigarette use varied widely among states, with estimates ranging from 3.1% (CI, 2.3% to 4.1%) in South Dakota to 7.0% (CI, 6.0% to 8.2%) in Oklahoma. Limitation: Data were self-reported, and no biochemical confirmation of tobacco use was available. Conclusion: E-cigarette use is common, especially in younger adults, LGBT persons, current cigarette smokers, and persons with comorbid conditions. The prevalence of use differs across states. These contemporary estimates may inform researchers, health care policymakers, and tobacco regulators about demographic and geographic distributions of e-cigarette use.

RESUMO

BACKGROUND: In high-income countries, quitting cigarette smoking is associated with weight gain, which can reduce motivation to abstain. Whether smoking cessation is associated with weight gain in a low-income country context has never been investigated. We aimed to determine the post-cessation changes in body mass index (BMI) and its predictors among smokers who received a smoking cessation intervention in a low-income country setting. METHODS: We performed post hoc analyses of data from 269 smokers who participated in a two-group, parallel-arm, double-blind, placebo-controlled randomized trial of combined nicotine replacement therapy (NRT) and behavioral counseling in primary care clinics in Aleppo, Syria. We used generalized estimating equation modeling to identify predictors of changes in BMI at 6 weeks and 6- and 12-month follow-ups after quit date. RESULTS: The mean pre-cessation BMI of the sample was 27.9kg/m2 (SD = 5.2). Over 12 months of follow-up, BMI of smoking abstainers averaged 1.8 BMI units (approximately 4.8kg) greater than non-abstainers (p = .012). Throughout the study, greater BMI was associated with being female (p = .048), reporting smoking to control weight (p < .001) and having previously failed to quit due to weight gain (p = .036). CONCLUSION: Similar to findings from high-income countries, smoking cessation in Syria is associated with weight gain, particularly among women and those who have weight concerns prior to quitting. This group of smokers may benefit from tailored cessation interventions with integrated body weight management elements that take into consideration the prevailing local and cultural influences on diet and levels of physical activity. IMPLICATIONS: This study provides the first evidence regarding post-cessation changes in BMI among smokers who attempt to quit in a low-income country setting. Our findings advance knowledge regarding post-cessation weight gain and offers insight for researchers and clinicians to identify smokers at higher risk of post-cessation weight gain. This information will help in delivering interventions that take into account the prevailing cultural influence on diet and physical activity and will ultimately help in designing future tailored cessation programs in Syria and other low-income countries with similar cultural background and level of development.

RESUMO

INTRODUCTION: Little evidence regarding longitudinal predictors of cigarette smoking progression is available from developing countries. This study aimed to identify gender-specific individual and social predictors of cigarette smoking progression among a school-based sample of adolescents in Irbid, Jordan. METHODS: A total of 1781 seventh graders (participation rate 95%) were enrolled and completed an annual self-administered questionnaire from 2008 through 2011. Students who reported "ever-smoking a cigarette" at baseline or in the subsequent follow-up but not being "heavy daily smokers" (>10 cigarettes per day) were eligible for this analysis (N = 669). Grouped-time survival analyses were used to identify predictors of cigarette smoking progression in boys and girls. RESULTS: Among the study sample, 38.3% of students increased the frequency and /or amount of cigarette smoking during the 3 years of follow-up. Among individual factors, the urge to smoke in the morning predicted smoking progression for boys and girls. The independent predictors of cigarette smoking progression were friends' smoking and attending public schools in boys, and siblings' smoking in girls. Discussing the dangers of smoking with family members was protective for girls. CONCLUSION: Boys and girls progressed similarly in cigarette smoking once they initiated the habit. Progression among girls was solely family-related, while it was peer-related for boys.

RESUMO

OBJECTIVES: In the past decade, waterpipe smoking (a.k.a. hookah, shisha, narghile) has become a global phenomenon. In this review, we provide an updated picture of the main epidemiological trends in waterpipe smoking globally. DATA SOURCES: Peer-reviewed publications indexed in major biomedical databases between 2004 and 2014. Search keywords included a combination of: waterpipe, hookah, shisha along with epidemiology, patterns, prevalence and predictors. We also used different spellings of waterpipe terms commonly used. STUDY SELECTION: The focus was on studies with large representative samples, national data or high-quality reports that illuminated aspects of the epidemiology and trends in waterpipe smoking. DATA EXTRACTION: Multiple researchers extracted the data independently and collectively decided on the most important and pertinent studies to include in the review. DATA SYNTHESIS: Waterpipe smoking has become a global phenomenon among youth. The global waterpipe epidemic is likely driven by (1) the introduction of manufactured flavoured tobacco (Maassel); (2) the intersection between waterpipe's social dimension and thriving café culture; (3) the evolution of mass communication media; (4) the lack of regulatory/policy framework specific to the waterpipe. Waterpipe smoking is becoming the most popular tobacco use method among youth in the Middle East, and is quickly gaining popularity elsewhere. Important patterns of waterpipe smoking include the predominance among younger, male, high socioeconomic, and urban groups. Intermittent and social use are also noted patterns. CONCLUSIONS: Waterpipe smoking has become a global public health problem. Developing surveillance, intervention and regulatory/policy frameworks specific to the waterpipe has become a public health priority.

RESUMO

AIMS: To assess the prevalence of the perceived safety of smoking a few (generally fewer than five per day) cigarettes during pregnancy and identify associated factors in a sample of pregnant smokers in Romania, a middle-income country. DESIGN AND SETTING: Cross-sectional design with a convenience sample using a polled data set collected between 2016 and 2019 in the formative and baseline phases of the Quit Together randomized control trial (RCT) in Romania. Data were collected using a structured questionnaire administered by research assistants in clinics in the formative phase and self-administered through the study website at the RCT baseline. PARTICIPANTS: A total of 217 pregnant smokers (mean age = 28.5 ± 5.8) enrolled in the formative and RCT phases of the research project. MEASUREMENTS: The main outcome was the perceived safety of smoking a few cigarettes during pregnancy (generally fewer than five per day). Covariates included the health-care providers' advice towards smoking tobacco cigarettes during pregnancy, socio-demographics, the presence of depression and anxiety symptoms and level of nicotine dependence. FINDINGS: More than 35% of participants agreed that smoking a few cigarettes during pregnancy was safe for them and their baby. The perceived safety of smoking a few cigarettes during pregnancy was significantly associated with being told by health-care providers that it is acceptable to continue to smoke cigarettes in small amounts [odds ratio (OR) = 3.08; 95% CI = 1.35-6.99; P < 0.01], perceived harm reduction of smoking light cigarettes (OR = 2.67; 95% CI = 1.19-5.97; P = 0.02) and moderate to severe depression and anxiety score (OR = 0.34; 95% CI = 0.13-0.84; P = 0.02). CONCLUSIONS: More than one-third of pregnant Romanian women appear to believe that smoking 'a few' cigarettes during pregnancy is safe for them and their fetuses. Those who are told by their health-care providers that it is acceptable to smoke in small amounts during pregnancy have higher odds of perceiving smoking 'a few' cigarettes during pregnancy as safe compared with other pregnant Romanian women.

RESUMO

Hispanic/Latinos are disproportionately represented in the criminal justice system. Using convenience sampling, the present study examined the lifetime and recent offending behavior of Hispanic/Latinos involved in community corrections in Miami, Florida. Descriptive statistics and multivariable logistic regression analyses were conducted. Participants were mostly male (59.7%), less than 40 years old (84.1%), and almost half were of Cuban descent (48.5%). Women were less likely to manufacture or sell drugs than men (AOR=.42, p<.03), and more likely to report recent prostitution (AOR=7.34, p< .001) and stealing from houses or shops (AOR=2.68, p<.01). Central Americans were less likely to report alcohol and drug related offenses than Cubans. Findings suggest that criminality among Hispanic/Latinos may vary by gender and by sub-groups. Prevention programs should be tailored accordingly.

RESUMO

OBJECTIVE: To assess the level of patients' satisfaction with primary health care PHC services in health centers affiliated to Riyadh Military Hospital RMH, Riyadh, Kingdom of Saudi Arabia. METHODS: A cross-sectional study was conducted in 3 PHC centers, affiliated to Riyadh Military Hospital RMH, Riyadh, Kingdom of Saudi Arabia, over 2 months period in 2006, data was collected using a self-administered questionnaire to assess patients' overall satisfaction with PHC services and their level of satisfaction with 5 PHC domains: reception services, accessibility, continuity of care, communication, and enablement. RESULTS: Seven hundred questionnaires were distributed yielding 86.6% response rate, 39.6% of our patients were 20-30 years old, 51.5% of the respondents were females, 76.4% were married and 34.5% of them showed a medical visit frequency of a minimum of 8 times per year. The domains of PHC with the highest level of reported satisfaction was enablement (70.6%). The poorest level of satisfaction was at the continuity of care (56.3%). The mean score of satisfaction with reception was 70.0%, communication 69.2%, and accessibility to care was 62.4%. The overall satisfaction level was 64.2%. Patients of older age were more satisfied with PHC services than their younger counterparts (p-value<0.001) and patients with lower education level were more satisfied (p-value<0.001). Patients' satisfaction was inversely related to their average annual visit frequency to PHC centers (p-value =0.015). There was no relation found between patients' satisfaction and their gender, marital status, occupational status, and their average monthly income. CONCLUSION: The level of satisfaction with PHC services in health centers affiliated to RMH is relatively low, results identified areas in which quality improvement is required, mainly accessibility and continuity of care.

RESUMO

BACKGROUND: To examine the prevalence and patterns of recent electronic cigarette (e-cigarette) use in a nationally representative sample of US adults and adolescents. METHODS AND RESULTS: Using tobacco information from NHANES (National Health and Nutrition Examination Survey) 2013-2014, 5423 adults and 895 adolescents (aged 13-17 years) were included in this analysis. Demographic, tobacco use, and drug use information were self-reported. Recent e-cigarette use (within the previous 5 days) was stratified by smoking status. Of 125 e-cigarette users, 116 participants were aged ≥18 years, corresponding to 2.6% (95% confidence interval [CI], 2.0-3.1) and 1.21% (95% CI, 0.3-2.1) prevalence of e-cigarette use among US adults and adolescents, respectively. E-cigarette adult users were current smokers (68.1%), former smokers (23.7%), and never smokers (8.2%). The highest prevalence of e-cigarette use was among current smokers (8.2%; 95% CI, 6.3-10.1), followed by former smokers (2.7%; 95% CI, 1.4-4.1), and then never smokers (0.4%; 95% CI, 0.2-0.6). After adjusting for age, sex, and ethnicity, e-cigarette users had higher odds of being exposed to secondhand smoke (odds ratio: 6.3; 95% CI, 3.6-11.1) and drinking alcohol (odds ratio: 4.2; 95% CI, 1.8-10.0) and lower odds of having at least a college education or a higher income, compared with tobacco nonusers. CONCLUSIONS: Between 2013 and 2014, e-cigarette use in the United States was more common among younger people, those with low socioeconomic status, and current and former smokers. These findings will help inform future research as well as public policy and regulatory actions.

RESUMO

INTRODUCTION: Waterpipe typically is smoked intermittently over long smoking sessions. Waterpipe is addictive and its users show symptoms of nicotine dependence (ND). This study examined the risk of developing ND symptoms across waterpipe use patterns among Lebanese youth. METHODS: Waterpipe use patterns (length of smoking session, smoking a whole waterpipe without sharing, past-30day use frequency, number of waterpipes smoked) were assessed. Symptoms of ND were assessed using the 10-item Hooked on Nicotine Checklist (HONC; endorsement of ≥1 symptom) and the 6 criteria of the International Classification of Diseases-10th revision (ICD-10 ND; presence of ≥3 criteria during 12months). RESULTS: Both the proportion of participants endorsing ND symptoms and the average number of endorsed ND symptoms increased with increasing waterpipe use frequency, number of waterpipes smoked, and length of smoking session. The risk of endorsing≥1 HONC symptom increased with increasing number of waterpipes smoked in the past 30-days (≥10 vs. <4 waterpipes; Hazard ratio (HR)=2.05, 95% CI: 1.52-2.58, p=0.007), and session length (>60min vs. <30min; HR=2.87, 95% CI: 2.83-2.91, p=0.001). The risk of attaining ICD-10 ND increased with increasing number of waterpipes used in the past 30-days (≥10 vs. <4 waterpipes; HR=2.56, 95% CI: 1.89-3.22, p=0.006), and smoking every day/almost every day vs. less than once weekly (HR=2.86, 95% CI: 2.12-3.60, p=0.007). CONCLUSIONS: Increasing use frequency, number of waterpipes smoked, and longer smoking sessions were associated with higher risk of ND. The length of smoking session emerged as a novel indicator of ND among waterpipe smokers.

RESUMO

OBJECTIVES: To identify predictors of nicotine withdrawal symptoms among smokers who participated in a randomized cessation trial in a low-income country. METHODS: We analyzed data from 269 smokers who participated in a randomized, placebo-controlled smoking cessation trial conducted in primary healthcare in Aleppo, Syria. All participants received behavioral counseling and were randomized to receive either 6 weeks of nicotine or placebo patch and were followed for one year. RESULTS: Throughout the study, lower total withdrawal score was associated with greater education (p = 0.044), older age of smoking initiation (p = 0.017), lower nicotine dependence (p = 0.024), higher confidence in ability to quit (p = 0.020), lower reported depression (p < 0.001), higher adherence to patch (p = 0.026), belief of receiving nicotine patches rather than placebo (p = 0.011), and waterpipe use (p = 0.047). CONCLUSIONS: Lower nicotine dependence, greater educational attainment, higher confidence in ability to quit and waterpipe use predict lower withdrawal severity. Waterpipe smoking may serve as a barrier to smoking cessation efforts in countries where its use is highly prevalent. Further, expectancies about the effects of pharmacotherapy appear to mediate the experience of nicotine withdrawal.

RESUMO

INTRODUCTION: Waterpipe smoking is addictive and its use is increasing globally among youth, yet little is known about the factors associated with nicotine dependence (ND) among waterpipe smokers. We investigated the factors associated with ND symptoms among a sample of Lebanese adolescents who smoke a waterpipe. METHODS: We collected data on factors potentially associated with ND (individual, socio-demographic, environmental, smoking patterns) among 160 current (past 30days) waterpipe smokers recruited from 8th and 9th school grades in Lebanon. We assessed the loss of autonomy over tobacco using the Hooked on Nicotine Checklist (HONC), ND using the International Classification of Diseases, 10th revision (ICD-10), and the number of ND symptoms endorsed. RESULTS: Depressive symptoms, lower self-esteem, and having at least one sibling who smokes a waterpipe were associated with the presence of ND symptoms, while enrollment in public schools, smoking a waterpipe ≥30min per session, and believing that cigarette smoking is harmful to health were associated with endorsement of a higher number of ND symptoms. Smoking a whole waterpipe head without sharing and being in 9th grade in this study were associated with the presence and endorsement of a higher number of ND symptoms. CONCLUSIONS: We identified specific social and psychological characteristics, waterpipe smoking patterns, and beliefs about harmful effects of smoking associated with the presence of ND among adolescent waterpipe smokers. Considering these factors when planning policies to prevent ND among waterpipe smokers is warranted.

RESUMO

BACKGROUND: The predictors of waterpipe smoking progression are yet to be examined using a longitudinal study that is guided by a theoretical model of behavioral change. This study identifies the gender-specific predictors of waterpipe smoking progression among adolescents in Irbid, Jordan. METHODS: This study uses data from a school longitudinal study of smoking behavior in Irbid, Jordan. A random sample of 19 schools was selected by probability proportionate to size. A total of 1781 seventh graders were enrolled at baseline, and completed a questionnaire annually from 2008 through 2011. Students who reported ever smoking waterpipe (N=864) at any time point were assessed for progression (escalation in the frequency of waterpipe smoking) in the subsequent follow-up. Grouped-time survival analysis was used to identify the risk of progression. RESULTS: During the three years of follow-up, 29.6% of students progressed in waterpipe smoking. Predictors of waterpipe smoking progression were higher mother's education, enrollment in public school, frequent physical activity, and low refusal self-efficacy among boys, having ever smoked cigarettes, and having friends and siblings who smoke waterpipe among girls. Awareness of harms of waterpipe was protective among boys and seeing warning labels on the tobacco packs was protective among girls. CONCLUSIONS: Even at this early stage, about a third of waterpipe smokers progressed in their habit during the 3 year follow up. Factors predicting progression of use differed by gender, which calls for gender-specific approaches to waterpipe interventions among Jordanian youth.

RESUMO

OBJECTIVE: Guided by the Attitude-Social influence-self Efficacy (ASE) theory, this study identified predictors of waterpipe (WP) smoking initiation in a WP naïve cohort of Jordanian school children. METHODS: A school-based cohort of all 7th grade students (N=1781) in 19 of 60 schools in Irbid, Jordan, was followed from 2008 to 2011. Generalized linear mixed modeling was used to examine predictors of WP initiation among WP-naïve students (N=1243). RESULTS: During the 3-year study, WP initiation was documented in 39% of boys and 28% of girls. Prior cigarette smoking (boys: odds ratio 7.41; 95% confidence interval 4.05-12.92 and girls: 8.48; 4.34-16.56) and low WP refusal self-efficacy (boys: 26.67; 13.80-51.53 and girls: 11.49; 6.42-20.55) were strongly predictive of initiating WP. Boys were also more likely to initiate WP smoking if they had siblings (2.30; 1.14-4.64) or teachers (2.07; 1.12-3.84) who smoked and girls if they had friends (2.96; 1.59-5.54) who smoked. CONCLUSION: There is a sizeable incidence of WP initiation among students of both sexes. These findings will help in designing culturally responsive prevention interventions against WP smoking. Gender-specific factors, refusal skills, and cigarette smoking need to be important components of such initiatives.

RESUMO

The Grip-ball is an innovative device that has been designed to measure grip strength. The Grip-ball consists of an airtight ball that contains a pressure sensor and Bluetooth communication system. The Grip-ball can be inflated to different initial pressures, with data available continuously in real time. The aim of this study was to build a model to predict the force applied to the Grip-ball dynamometer based only on the pressure measured by the Grip-ball and its initial pressure. Forces ranging from 2 to 70 kg were applied to a hybrid version of the device for 10 different initial pressures, ranging from atmospheric pressure of 100 kPa through to 190 kPa. A model was constructed to predict applied force, with force as a function of the initial pressure and the pressure measured. The error of the model was calculated as 1.29 kg across all initial pressures and forces applied. The results of the study are comparable with the errors observed for the gold standard in grip force measurement, the Jamar dynamometer. The best results for force prediction were obtained over the range in which frailty is typically detected. The Grip-ball will now be tested using a large population in order to establish clinical norms.

RESUMO

BACKGROUND: Anemia in patients with cancer who are undergoing active therapy is commonly encountered and may worsen quality of life in these patients. The effect of blood transfusion is often temporary and may be associated with serious adverse events. Erythropoiesis-stimulating agents are not effective in 30%-50% of patients and may have a negative effect on overall survival. AIMS: To assess the efficacy and feasibility of intravenous iron therapy in patients with cancer who have non-iron-deficiency anemia and who are undergoing treatment with chemotherapy without the use of erythropoiesis-stimulating agents. METHODS: Adult patients with solid cancers and non-iron-deficiency anemia were included. Ferric sucrose at a dose of 200 mg was given in short intravenous infusions weekly for a total of 12 weeks. Hemoglobin level was measured at baseline, every 3 weeks, and 2 weeks after the last iron infusion (week 14). Adverse events related to intravenous iron were prospectively reported. RESULTS: Of 25 patients included, 19 (76.0%) completed at least three iron infusions and 14 (56.0%) finished the planned 12 weeks of therapy. The mean hemoglobin level of the 25 patients at baseline was 9.6 g/dL (median, 9.9 g/dL; range, 6.9 g/dL 10.9 g/dL). The mean change in hemoglobin level for the 15 patients who completed at least 9 treatments was 1.7 g/dL (median, 1.1 g/dL; range, -1.9 g/dL to 3.2 g/dL); it reached 2.1 g/dL (median, 1.3 g/dL; range, -0.2 g/dL to 4.6 g/dL; P = 0.0007) for the 14 patients who completed all 12 weekly treatments. Five (20.0%) patients were transfused and considered as treatment failures. No treatment-related adverse events were reported. CONCLUSION: Intravenous iron treatment alone is safe and may reduce blood transfusion requirements and improve hemoglobin level in patients with cancer who are undergoing anticancer therapy. Further randomized studies are needed to confirm these findings.

RESUMO

Frailty is of increasing concern due to the associated decrease in independence of elderly who suffer from the condition. An innovative system was designed in order to objectively quantify the level of frailty based on a series of remote tests, each of which used objects similar to those found in peoples' homes. A modified ball, known as the Grip-ball was used to evaluate maximal grip force and exhaustion during an entirely remote assessment. A smartphone equipped with a tri-axial accelerometer was used to estimate gait velocity and physical activity level. Finally, a bathroom scale was used to assess involuntary weight loss. The smart phone processes all of the data generated, before it is transferred to a remote server where the user, their entourage, and any medical professionals with authorization can access the data. This innovative system could enable the onset of frailty to be detected early, thus giving sufficient time for a targeted intervention program to be implemented, thereby increasing independence for elderly users.

RESUMO

The Grip-ball is a new dynamometer used to evaluate grip strength, as well as for use in home-based rehabilitation of the hand and forearm. The Grip-ball consists of pressure and temperature sensors and an electronic wireless communication system contained in an airtight ball. That can be inflated to different pressures. The device has advantages over standard dynamometers in that it looks like a simple ball, and can wirelessly communicate via Bluetooth to any compatible receiver, thus have potential to be used for clinical assessment and rehabilitation in a remote setting. The reliability and reproducibility of the device were assessed for the pressure sensor itself, as well as the relationship between the force applied and the pressure measured by the Grip-ball. The initial validation was performed using the pressure sensor without the ball in order to confirm the accuracy of the sensor used. A second validation study was conducted using the Grip-ball rather than just its sensor to examine the relationship between the pressure measured inside the ball and force applied. The results showed that there is a very good correlation (r=0.997, p<0.05) between the pressure measured by the Grip-ball sensor and that measured by a Vigorimeter, thus confirming the reliability of the sensor used in the Grip-ball. A quadratic regression equation was calculated in order to predict the force applied based on the pressure measured inside the ball, and the initial pressure to which the ball was inflated (R(2)=0.97, standard error 10.9N). Such a finding compares favourably with the variability inherent in Jamar recordings, thus indicating that the Grip-ball could be used to assess grip force. An industrial version of the Grip-ball, which is currently under development, will be able to be used for the entire range of grip force in the population.
