Factors Underlying Variation in Receipt of Physician Advice on Diet and Exercise: Applications of the Behavioral Model of Health Care Utilization

Provision of physical activity advice for patients with chronic diseases in Shenzhen, China

BACKGROUND

Physical activity (PA) may best be promoted to patients during clinical consultations. Few studies investigated the practice of PA advice given by physicians, especially in China. This study aimed to investigate the prevalence and contents of PA advice given by physicians in China and its association with patients' characteristics.

METHODS

Face-to-face questionnaire asking the prevalence and contents of PA advice given by physicians was administered to adult patients in three major hospitals in Shenzhen, China. Attitude of compliance, stature, PA level, and socio-demographic information were also collected. Data was analyzed via descriptive statistics and binary logistic regression.

RESULTS

Of the 454 eligible patients (Age: 47.0 ± 14.4 years), only 19.2% (n = 87) reported receiving PA advice, whereas 21.8%, 23.0%, 32.2%, and 55.2% of patients received advices on PA frequency, duration, intensity, and type, respectively. Male patients were more likely to receive PA advice from physicians [odds ratio (OR): 1.81; 95% confidence interval (CI): 1.08-3.05], whereas patients who were unemployed (OR: 0.16; 95% CI: 0.04-0.67), and who already achieved adequate amount of PA (OR: 0.29; 95% CI: 0.12-0.71) were less likely to receive PA advice.

CONCLUSIONS

Prevalence of physicians providing physical activity advice to patients is low, there is a pressing need to take intervention measures to educate healthcare providers.

Expectations about check-up examinations among Swiss residents: A nationwide population-based cross-sectional survey

INTRODUCTION

General health check-up examinations in asymptomatic adults have not been shown to be beneficial. Instead, opportunistic prevention during regular primary care consultations is most cost-effective and recommended. The study aimed to elucidate the expectations about check-ups of the general Swiss population.

METHODS

A nationwide cross-sectional telephone survey was conducted in a representative sample of the population, stratified by sex, age, and language in November 2019.

RESULTS

Data of 1077 respondents were analysed. Mean age was 45 years (range 18 to 89), and 51% were female. Overall, 40% of respondents expected to have check-up examinations (yearly: 41.6%), and 42% expected opportunistic prevention. Most expected check-up interventions were sex-specific such as mammography (89% of women), Pap smear test (89% of women), and blood test of prostate-specific antigen (81% of men). The least favoured ones related to counselling (tobacco: 27%; alcohol abuse: 29%). Most significant predictors of positive check-up expectations were being male (OR = 1.45, CI: 1.02-2.05 P = 0.04)), age between 45 and 59 years old (OR = 2.03, CI: 1.27-3.23, P = 0.003 vs. 18 to 29 years), having a degree from professional (OR = 1.73, 95% CIs: 1.11-2.69, P 0.015) or, middle school (OR = 1.99, 95% CIs:1.04-3.78, P = 0.037) or university (OR = 1.66, 95% CIs: 1.06-2.61, P< 0.001, vs. secondary school) and the more importance attributed to regularly checking one's health (OR = 2.12, 95% CIs: 1.70-2.36, P < 0.001).

CONCLUSIONS

Almost half of the population expected to have mostly yearly check-up examinations in addition to regular care, which is in contradiction to recommendations. This behaviour impacts the rational use of health care resources and must be considered by physicians and given the active role of patients in the health care system.

Physical Activity Counseling among Adults in Primary Health Care Centers in Brazil

Physical activity (PA) counseling by health professionals has promising results in behavior change. However, few studies have evaluated its prevalence in Primary Health Care in Latin American countries. This study aimed to describe the prevalence and analyze the associated factors of PA counseling in adults in Primary Health Care in Brazil. This is a cross-sectional study with a representative sample of 779 adults (70% women). Counseling was identified among those who reported having received PA counseling during a health professional consultation in the last 12 months. Sociodemographic factors, health conditions, and leisure-time PA were analyzed with Poisson regression. The prevalence of counseling was 43% (95% Confidence Interval [CI]: 39.5-46.4%), higher in people aged ≥40 years (Prevalence Ratio [PR]: 1.44; 95% CI: 1.19-1.75], who are married (PR: 1.27; 95% CI: 1.07-1.59), obese (PR: 1.53; 95% CI: 1.23-1.90), take prescription medication (PR: 1.83; 95% CI: 1.47-2.27), and walk for leisure (PR: 1.28; 95% CI: 1.06-1.54). People with more education were less likely to receive PA counseling (PR: 0.82; 95% CI: 0.68-0.99). In conclusion, 4 out of 10 users reported receiving PA counseling and this was associated with sociodemographic factors, health conditions, and walking for leisure. These results can guide PA promotion in Primary Health Care.

Healthcare provider counselling for weight management behaviours among adults with overweight or obesity: a cross-sectional analysis of National Health and Nutrition Examination Survey, 2011-2018

OBJECTIVES

To determine if adults with overweight or obesity received counselling from their healthcare providers (HCPs) to lose weight and/or adopt healthful behaviours associated with weight loss, and whether they took action on their HCPs' recommendations.

DESIGN

Cross-sectional analysis of 2011-2018 National Health and Nutrition Examination Survey (NHANES) data.

SAMPLE

NHANES respondents aged 18+ who were overweight/obese and had seen an HCP in the previous 12 months (n=13 158).

METHODS

Respondents reported if their HCPs recommended they control/lose weight, increase exercise/physical activity (PA) and/or reduce fat/calorie intake, and if they adopted the offered recommendation(s). Weighted logistic regression models examined receipt of HCP counselling by sex, age, race/ethnicity, and weight status accounting for demographic characteristics and complex sampling. Similar analyses examined reported adoption of HCPs' recommendations.

RESULTS

The sample was 53.1% women, 45.0% were overweight and 55.0% had obesity. In total, 40.4% received counselling to control/lose weight, 49.5% to increase exercise/PA and 38.9% to reduce fat/calorie intake. The following groups were less likely (p<0.001) to receive counselling: men; younger adults (aged 18-39) versus middle-aged (aged 40-64) and older adults (aged 65+); White versus Black and Hispanic respondents; overweight respondents versus respondents with obesity. Approximately half of those advised to make changes reported doing so (53.6% controlled/lost weight, 57.3% increased exercise/PA, 51.8% reduced fat/calorie intake). Differences in the adoption of recommendations were identified by sex, age group, race/ethnicity and weight status (all p<0.05); women, middle-aged and older adults, Black and Hispanic respondents and individuals with obesity were more likely to adopt one or more recommendations.

CONCLUSION

Most respondents did not receive HCP counselling, and approximately half of those who received counselling reported taking action. HCPs may need training to provide counselling and to offer recommendations tailored to the social contexts of populations less likely to adopt weight control related recommendations.

Racial/ethnic variations in weight management among patients with overweight and obesity status who are served by health centres

This study sought to examine racial/ethnic variations in receipt of provider recommendations on weight loss, patient adherence, perception of weight, attempts at weight loss and actual weight loss among patients with overweight/obesity status at Health Resources and Services Administration-funded health centres (HC). We used a 2014 nationally representative survey of adult HC patients with overweight/obesity status (PwOW/OB) last year and reported the HC was their usual source of care (n = 3517). We used logistic regression models to assess the interaction of race/ethnicity and having obesity in (1) provider recommendations of diet or (2) exercise, (3) patient adherence to diet or (4) exercise, (5) perceptions of weight and (6) weight loss attempts. We used a multinomial regression model to examine (7) weight loss or gain vs no change and a linear regression model to evaluate (8) percent weight change. We found Black PwOW/OB (OR = 1.65) experienced greater odds of receiving diet recommendations than Whites. We found limited racial/ethnic disparities in adherence. Black (OR = 0.41), Hispanic/Latino (OR = 0.45), and American Indian/Alaska Native (OR = 0.41) PwOW/OB had lower odds of perceiving themselves as overweight. Black (OR = 1.68) and Hispanic (OR = 1.98) PwOW/OB had a greater odds of reporting weight gain, and Asian PwOW/OB (OR = 0.42) had lower odds of reporting weight loss than Whites. Disparities in provider diet recommendations among Blacks and Hispanics indicated the importance of personalized weight management recommendations. Understanding underlying reasons for discordance between self-perception and observed weight among different groups is needed. Overall increase in weight, despite current interventions, should be addressed through targeted racially/ethnically appropriate approaches.

Identifying patterns and predictors of lifestyle modification in electronic health record documentation using statistical and machine learning methods

Just under half of the 85.7 million US adults with hypertension have uncontrolled blood pressure using a hypertension threshold of systolic pressure ≥ 140 or diastolic pressure ≥ 90. Uncontrolled hypertension increases risks of death, stroke, heart failure, and myocardial infarction. Guidelines on hypertension management include lifestyle modification such as diet and exercise. In order to improve hypertension control, it is important to identify predictors of lifestyle modification assessment or advice to tailor future interventions using these effective, low-risk interventions. Electronic health record data from 14,360 adult hypertension patients at an academic medical center were analyzed using statistical and machine learning methods to identify predictors and timing of lifestyle modification. Multiple variables were statistically significant in analysis of lifestyle modification documentation at multiple time points. Random Forest was the best machine learning method to classify lifestyle modification documentation at any time with Area Under the Receiver Operator Curve (AUROC) 0.831. Logistic regression was the best machine learning method for classifying lifestyle modification documentation at ≤3 months with an AUROC of 0.685. Analyzing narrative and coded data from electronic health records can improve understanding of timing of lifestyle modification and patient, clinic and provider characteristics that are correlated with or predictive of documentation of lifestyle modification for hypertension. This information can inform improvement efforts in hypertension care processes, treatment implementation, and ultimately hypertension control.

Adults and the elderly who received nutritional counseling in a city of southern Brazil: a population-based study

INTRODUCTION

Nutrition counseling has played a critical role in the prevention and treatment of various diseases.

OBJECTIVE

To evaluate how adults and elderly people, who are residents in an urban area of Southern Brazil, received nutritional counseling.

METHODS

This was a cross-sectional population based study. Data was collected through a questionnaire applied at home. The outcome was the prevalence of nutritional counseling received in the past year that came from different means, including means of communication. Sociodemographic variables, doctor visits in the past year, nutritional state and other healthcare variables were analyzed.

RESULTS

The sample included 1,296 individuals (rate of answer of 90.7%). The results indicate that the majority of the people interviewed were females (56.6%), with their age ranging from 18 to 59 years-old (75.3%). The prevalence of people receiving nutritional counseling was 19.9% (95%CI 17.3 -22.5). It was higher among women than men (p = 0.01). The sex-adjusted analyses showed a statistically significant (p < 0.05) association in men for the variables: schooling ≥ 12 years; medical consultation in the last year; low weight; obesity; diabetes and hypertension. Among the women, the following variables were associated with the outcome: health insurance; medical consultation in the last year; obesity and diabetes.

CONCLUSIONS

The low prevalence of nutritional counseling and its association with diseases exposes the need for it to be implemented not only for treatment purposes but also as preventive health actions.

Women's recall of health care provider counselling on gestational weight gain (GWG): a prospective, population-based study

BACKGROUND

Prenatal care has been validated to provide medical and educational counselling intended to reduce the risk of adverse pregnancy conditions and improve the maternal and fetal outcomes. Prenatal targeted information regarding nutrition, lifestyle, and weight gain is predictive of meeting Institute of Medicine (IOM) 2009 gestational weight gain (GWG) guidelines. There is limited information about women's experiences with these prenatal counselling domains, particularly in women who do not meet GWG recommendations. The objective of this study was to evaluate the impact of women's recall of prenatal counselling and its effect on meeting their GWG within guidelines in a prospective, community-based pregnancy cohort.

METHODS

A sample of 2909 women with singleton pregnancies was drawn from the prospective community-based pregnancy cohort All Our Families from Alberta, Canada. Women were stratified into three GWG groups, adequate, inadequate, and excessive GWG, based on pre-pregnancy BMI and the adherence to the Institute of Medicine weight gain in pregnancy guidelines. At less than 25 and 34 to 36 weeks' gestation, maternal socio-demographic information and women's recall of prenatal counselling experiences was collected through self-administered questionnaires. Multivariate logistic regression analyses tested GWG strata impact on women's recall of the prenatal counselling advice in eight domains of nutrition, lifestyle, and weight management during pregnancy.

RESULTS

Adequate GWG was reached by 35.9% of women, 46.5% gained excessive and 17.6% gained inadequate weight. Women who were overweight and obese prior to pregnancy were more likely to gain excessive weight than women who were normal weight (OR 3.3, 95% CI 2.6-4.1; and OR 2.9, 95% CI 2.1-3.9, respectively). Most women reported having no difficulties in finding prenatal care, felt comfortable with their health care provider and were satisfied with the answers received. There was no difference in the recall of prenatal advice received in any of the eight domains of prenatal counselling assessed among women with appropriate and non-optimal GWG.

CONCLUSION

Women with adequate and non-optimal GWG received comparable prenatal counselling on nutrition, weight gain, and lifestyle modifications. There remain missed opportunities in targeting prenatal counselling advice to women at risk for suboptimal or excessive GWG.

Exercise Is Medicine: Primary Care Counseling on Aerobic Fitness and Muscle Strengthening

Patient counseling on physical fitness remains underutilized in primary care, despite its clinical and cost effectiveness. Most counseling interventions have focused on aerobic activity and neglected another vital component of physical fitness, muscle strengthening, which has recently been shown to be independently protective against cardiometabolic diseases and premature mortality. This article reviews the latest scientific evidence and makes recommendations toward a more comprehensive approach for promoting physical fitness in primary care. Given the high prevalence and wide-ranging health impacts of physical inactivity, counseling on physical fitness should be a standard part of wellness promotion and disease prevention and treatment for all patients. Interventions that include muscle strengthening will have a significantly greater impact on health outcomes than those focused on aerobic fitness alone. Counseling to promote both aerobic fitness and muscle strengthening is indicated for all patients, irrespective of body weight, and should begin early in life and continue across the life course.

Recall of Prenatal Counselling Among Obese and Overweight Women from a Canadian Population: A Population Based Study

Objective The objective of this study was to evaluate the recall of prenatal counselling received among overweight and obese women in primary care settings. Methods A sample of 1996 women with singleton, term deliveries and pre-pregnancy BMI >18.5 kg/m² were identified from the All Our Babies pregnancy cohort. Information on socio-demographic characteristics and women's experiences with prenatal counselling on nutrition, vitamin and mineral supplements, exercise, weight gain, employment, alcohol and drug use, and smoking during pregnancy were collected through questionnaires administered at <25 weeks and 34-36 weeks gestation. Multivariable logistic regression analyses explored the associations between pre-pregnancy BMI and the domains of prenatal counselling, controlling for confounders. Results Women reported high levels of comfort asking questions and satisfaction with their health care provider. Women reported getting information about nutrition (69.3%), weight gain (67.8%), exercise (64.4%), vitamins and minerals supplementation (86.1%). Obese women (211, 10.6%) were more likely than normal weight women (1313, 65.8%) to be Caucasian (p = 0.004), less educated (p = 0.001), and to have been born or lived in Canada for at least 5 years (p = 0.01). There was no difference in the prenatal advice received on nutrition, weight gain and exercise in pregnancy between obese, overweight, and normal weight women. Conclusions for Practice Pre-pregnancy BMI did not appear to influence the recall of prenatal counselling women receive in community health care centers. Given the importance of nutrition and weight gain during pregnancy, and guidelines for weight gain based on pre-pregnancy BMI, there are missed opportunities in knowledge exchange between women and providers in the prenatal period.

Healthcare Providers' Recommendations for Physical Activity among US Arthritis Population: A Cross-Sectional Analysis by Race/Ethnicity

Introduction

We examined racial/ethnic disparities in healthcare providers' recommendations for physical activity among individuals with arthritis and evaluated this association among groups of individuals who adhered to physical activity guidelines and those who did not.

Methods

With a cross-sectional design based on Behavioral Risk Factor Surveillance System, we analyzed individuals with self-reported physician-diagnosed arthritis, ≥18 years of age (n = 83,376). Outcome variable was healthcare providers' recommendations for physical activity. Race/ethnicity was categorized as African American, Hispanic, and White. Associations were examined using multivariate logistic regression.

Results

African Americans (Adjusted OR: 0.66; 95% CI: 0.55–0.79) and Hispanics (Adjusted OR: 0.68; 95% CI: 0.56–0.83) were less likely to receive providers' recommendations.

Conclusions

Although the importance of physical activity to improve health outcomes for adults with arthritis, as well as providers' influence on individuals' behavior change, is well established, providers are less likely to recommend physical activity to minorities. Further studies are required to identify the causes for this quality-of-care issue.

Nurse Practitioners and Men's Primary Health Care

Though life expectancy sex differences are decreasing in many Western countries, men experience higher mortality rates at all ages. Men are often reluctant to seek medical care because health help-seeking is strongly linked to femininity, male weakness, and vulnerability. Many men are also more likely to access emergency care services in response to injury and/or severe pain instead of engaging primary health care (PHC) services. Nurse practitioners are well positioned to increase men's engagement with PHC to waylay the pressure on emergency services and advance the well-being of men. This article demonstrates how nurse practitioners can work with men in PHC settings to optimize men's self-health and illness prevention and management. Four recommendations are discussed: (1) leveling the hierarchies, (2) talking it through, (3) seeing diversity within patterns, and (4) augmenting face-to-face PHC services. In terms of leveling the hierarchies nurse practitioners can engage men in effectual health decision making. Within the interactions detailed in the talking it through section are strategies for connecting with male patients and mapping their progress. In terms of seeing diversity with in patterns and drawing on the plurality of masculinities, nurse practitioners are encouraged to adapt a variety of age sensitive assessment tools to better intervene and guide men's self-health efforts. Examples of community and web based men's health resources are shared in the augmenting face-to-face PHC services section to guide the work of nurse practitioners. Overall, the information and recommendations shared in this article can proactively direct the efforts of nurse practitioners working with men.

Trends and disparities in the prevalence of physicians' counseling on exercise among the U.S. adult population, 2000-2010

Recognizing the undisputed health benefits of exercise, physicians' counseling has been included in the Healthy People Objectives since 2000. To address the paucity of data on such counseling at the national level, we examined changing trends and disparities in receiving physicians' counseling on exercise among the physically-able, non-institutionalized U.S. adult population. Data from the 2000, 2005, and 2010 National Health Interview Surveys (NHIS) were examined using logistic regression that included race/ethnicity, age, gender, education, insurance status, number of physician visits in the past year, and body mass index. In 2000, only 22.9% of NIHS respondents had received counseling on exercise, increasing to 33.6% in 2010. Compared with non-Hispanic Whites, non-Hispanic Blacks were 27% less likely to receive exercise advice in 2000 (adjusted odds ratio [AOR] 0.73, 95% confidence interval [CI] 0.61-0.87). In later years, they were equally likely to receive advice. Although decreased over the years, male respondents were significantly (34% to 23%) less likely to report receipt of exercise counseling than female patients (in 2010: AOR 0.77, CI 0.72-0.83). Uninsured respondents were 35% less likely to report receiving exercise advice from their provider in all study years (2010: AOR 0.64, CI 0.59-0.72). Patients with increasing levels of education were increasingly more likely to report receipt of counseling in each successive survey year. The overall prevalence of physicians' counseling on exercise increased moderately between 2000 and 2010. Some disparities narrowed and even reversed but significant disparities continue to exist across gender, insurance status, and education level.

Changes in primary healthcare providers' attitudes and counseling behaviors related to dietary sodium reduction, DocStyles 2010 and 2015

High blood pressure is a major risk factor for cardiovascular disease. The 2013 ACC/AHA Lifestyle Management Guideline recommends counseling pre-hypertensive and hypertensive patients to reduce sodium intake. Population sodium reduction efforts have been introduced in recent years, and dietary guidelines continued to emphasize sodium reduction in 2010 and 2015. The objective of this analysis was to determine changes in primary health care providers' sodium-reduction attitudes and counseling between 2010 and 2015. Primary care internists, family/general practitioners, and nurse practitioners answered questions about sodium-related attitudes and counseling behaviors in DocStyles, a repeated cross-sectional web-based survey in the United States. Differences in responses between years were examined. In 2015, the majority (78%) of participants (n = 1,251) agreed that most of their patients should reduce sodium intake, and reported advising hypertensive (85%), and chronic kidney disease patients (71%), but not diabetic patients (48%) and African-American patients (43%) to consume less salt. Since 2010, the proportion of participants agreeing their patients should reduce sodium intake decreased while the proportion advising patients with these characteristics to consume less salt increased and the prevalence of specific types of advice declined. Changes in behaviors between surveys remained significant after adjusting for provider and practice characteristics. More providers are advising patients to consume less salt in 2015 compared to 2010; however, fewer agree their patients should reduce intake and counseling is not universally applied across patient groups at risk for hypertension. Further efforts and educational resources may be required to enable patient counseling about sodium reduction strategies.

Correlates of Receiving a Recommendation for More Physical Activity From a Primary Care Provider

INTRODUCTION

Primary care providers (PCPs) are strategically positioned to communicate with their overweight/obese patients about positive behavioral changes to improve health and functioning. Demographic and behavioral correlates of receiving a recommendation for more physical activity (PA) from a PCP by overweight/obese patients were assessed.

METHODS

Community-dwelling adults aged ≥50 years from four Texas cities who were seen by a family physician in a primary care clinic were surveyed from October 2013 to June 2014. Multivariate logistic regression predicted the likelihood of receiving a PA recommendation from a PCP, controlling for sociodemographic factors, health conditions, and walking behaviors. The analysis was conducted in 2016.

RESULTS

Of the total 388 participants (survey response rate, 6.8%), 30.1% were obese, 55.4% were female, and most were non-Hispanic white (82.9%), married (75.6%), or reported an annual household income of ≥$50,000 (66.8%). Receipt of a PA recommendation from a PCP (n=151, 38.9%) was significantly correlated with reporting poor to fair health (OR=7.33, 95% CI=2.6, 20.32), obesity (OR=2.95, 95% CI=1.69, 5.14), having only a little or some difficulty walking for a quarter of a mile (OR=2.94, 95% CI=1.41, 5.88), not walking the recommended ≥150 minutes for any purpose (OR=2.60, 95% CI=1.25, 5.38), and being employed (OR=2.11, 95% CI=1.13. 3.94).

CONCLUSIONS

PCPs seem to be targeting obese, inactive individuals with poor to fair health, populations traditionally not encouraged to be more physically active. These findings are consistent with the current trend in medical care to recommend positive lifestyle changes to a broader range of the population.

Trends and disparities in the prevalence of physicians' counseling on diet and nutrition among the U.S. adult population, 2000-2011

BACKGROUND

Although healthy eating plays a crucial role in addressing the obesity and chronic disease epidemics, a few Americans have diets that meet dietary guidelines. Because physicians-delivered counseling is a strong predictor for behavioral modification among patients, the Healthy People Objectives have emphasized diet counseling since 2000. However, research on impact of physicians' counseling over time on a national level has been limited.

METHODS

We used data from the 2000 and 2011 National Health Interview Surveys to apply a logistic regression model to identify predictors of physicians' counseling and examine any changes in disparities over a decade.

RESULTS

In 2000, only 23.7% of our national sample had received dietary counseling, it increased to 32.6% in 2011. Hispanics were less likely than Whites to receive advice on diet in 2000 (adjusted odds ratio [AOR]=0.74, 95% confidence interval [CI]=0.62-0.88). By 2011, Hispanics 18% (AOR=1.18, CI=1.09-1.28) and Blacks were 42% (AOR=1.42, CI=1.32-1.54) more likely to receive advice from their physicians on diet than Whites. In both years, men were significantly less likely than women to receive counseling. The uninsured patients were increasingly less likely than insured patients in receiving diet counseling, being 60% less likely in 2011 (AOR=0.40, CI=0.37-0.40). Obese patients were substantially (88% in 2000 to 290% in 2011) more likely to receive counseling than normal-weight patients.

CONCLUSIONS

The overall prevalence of physicians' counseling on diet increased moderately between 2000 and 2011. However, substantial disparities in dietary counseling related to access to care and gender continue to exist.

Self-reported receipt of healthcare professional's weight management counselling is associated with self-reported weight management behaviours of type 2 diabetes mellitus patients

BACKGROUND

Weight loss has been shown to influence the health outcomes of type 2 diabetes patients. Providing weight management counselling to diabetes patients may help them adopt appropriate weight management behaviours to lose weight. This study determined the association between self-reported receipt of healthcare professional's weight management counselling and the weight management behaviours of type 2 diabetes patients.

METHODS

This cross-sectional study was conducted among 378 type 2 diabetes mellitus patients seeking care from two hospitals. Using a questionnaire, participants' weight management behaviours were assessed as well as receipt of healthcare professional's weight management counselling.

RESULTS

Half (51.3 %) of the participants reported receipt of healthcare professional's weight management counselling in the last 12 months. Half of the participants ever tried to lose weight. Fewer than half of the participants reported modifying their dietary habits (45.5 %) or engaging in exercise (48.7 %) to lose weight. Those who reported receipt of weight management counselling were more likely to report ever trying to lose weight (AOR 43.0, 95 % CI 23.0-81.6; p < 0.001), modifying their dietary habits (AOR 22.5, 95 % CI 13.0-39.19; p < 0.001), and engaging in exercise (AOR 13.0, 95 % CI 7.8-21.7; p < 0.001) to lose weight.

CONCLUSION

Participants engaged in varied weight management behaviours. Receipt of health care professionals' weight management counselling was associated to participants' reported participation in weight management behaviours. Weight management counselling from health care professionals may support the adoption of weight management behaviours in type 2 diabetes mellitus patients.

Emergency Department Frequent Utilization for Non-Emergent Presentments: Results from a Regional Urban Trauma Center Study

OBJECTIVES

First, to test a model of the drivers of frequent emergency department utilization conceptualized as falling within predisposing, enabling, and need dimensions. Second, to extend the model to include social networks and service quality as predictors of frequent utilization. Third, to illustrate the variation in thresholds that define frequent utilization in terms of the number of emergency department encounters by the predictors within the model.

DATA SOURCE

Primary data collection over an eight week period within a level-1 trauma urban hospital's emergency department.

STUDY DESIGN

Representative randomized sample of 1,443 adult patients triaged ESI levels 4-5. Physicians and research staff interviewed patients as they received services. Relationships with the outcome variable, utilization, were tested using logistic regression to establish odds-ratios.

PRINCIPAL FINDINGS

70.6 percent of patients have two or more, 48.3 percent have three or more, 25.3 percent have four or more, and 14.9 percent have five or more emergency department visits within 12 months. Factors associated with frequent utilization include gender, race, poor mental health, mental health drugs, prescription drug abuse, social networks, employment, perceptions of service quality, seriousness of condition, persistence of condition, and previous hospital admittance.

CONCLUSIONS

Interventions targeting associated factors will change global emergency department encounters, although the mutability varies. Policy interventions to address predisposing factors such as substance abuse or access to mental health treatment as well as interventions that speak to enabling factors such as promoting the resiliency of social networks may result in decreased frequency of emergency department utilization.

Parents' decision making and access to preventive healthcare for young children: applying Andersen's Model

BACKGROUND AND OBJECTIVE

Implementing preventive health care for young children provides the best chance of improving health and changing a child's life course. In Australia, despite government support for preventive health care, uptake of preventive services for young children is low. Using Andersen's behavioural model of health-care utilization, we aimed to understand how parents conceptualized their children's preventive health care and how this impacted on access to preventive health-care services.

DESIGN

Semi-structured telephone interviews conducted between May and July 2011.

SETTING AND PARTICIPANTS

Twenty-eight parents of children aged 3-5 years from three diverse socio-economic areas of Melbourne, Australia.

RESULTS

Thematic analysis showed parents' access to child preventive health care was determined by birth order of their child, cultural health beliefs, personal health practices, relationship with the health provider and the costs associated with health services. Parents with more than one child placed their own experience ahead of professional expertise, and their younger children were less likely to complete routine preventive health checks. Concerns around developmental delays required validation through family, friends and childcare organizations before presentation to health services.

CONCLUSIONS

To improve child preventive health requires increased flexibility of services, strengthening of inter-professional relationships and enhancement of parents' knowledge about the importance of preventive health in early childhood. Policies that encourage continuity of care and remove point of service costs will further reduce barriers to preventive care for young children. Recent reforms in Australia's primary health care and the expansion of child preventive health checks into general practice present a timely opportunity for this to occur.

Physicians', nurses' and community health workers' knowledge about physical activity in Brazil: A cross-sectional study

OBJECTIVES

To measure knowledge of current recommendations of physical activity and consequences of physical inactivity among healthcare providers throughout Brazil.

METHODS

A phone survey of 1600 randomly selected primary healthcare units in Brazil was conducted between January and July 2011. At each unit, a physician, nurse or community healthcare worker (n = 798) responded to a 40-minute survey, eliciting information about demographics, knowledge, and health behaviors pertaining to physical activity.

RESULTS

Among nurses and community healthcare workers, > 95% reported needing more information on physical activity guidelines. Among physicians this proportion was 80%. Nearly 40% of the professionals incorrectly believed 90-min of moderate-intensity physical activity per week is the recommended amount for health benefits; nearly 30% believed that 90-min of vigorous-intensity activity per week is needed for the same purpose. More than 75% of all groups reported that type II diabetes, hypertension, depression, and coronary heart disease might result from physical inactivity, but on average only 60% from each group are aware of osteoporosis as a possible consequence of physical inactivity.

CONCLUSIONS

Training health professionals in how to convey all relevant information about physical activity to their patients is critical for health promotion within the primary care system in Brazil.

Organization of Primary Care Practice for Providing Energy Balance Care

Purpose.

Primary care physicians (PCPs) may not adequately counsel or monitor patients regarding diet, physical activity, and weight control (i.e., provide energy balance care). We assessed the organization of PCPs' practices for providing this care.

Design.

The study design was a nationally representative survey conducted in 2008.

Setting.

The study setting was U.S. primary care practices.

Subjects.

A total of 1740 PCPs completed two sequential questionnaires (response rate, 55.5%).

Measures.

The study measured PCPs' reports of practice resources, and the frequency of body mass index assessment, counseling, referral for further evaluation/management, and monitoring of patients for energy balance care.

Analysis.

Descriptive statistics and logistic regression modeling were used.

Results.

More than 80% of PCPs reported having information resources on diet, physical activity, or weight control available in waiting/exam rooms, but fewer billed (45%), used reminder systems (< 30%), or received incentive payments (3%) for energy balance care. A total of 26% reported regularly assessing body mass index and always/often providing counseling as well as tracking patients for progress related to energy balance. In multivariate analyses, PCPs in practices with full electronic health records or those that bill for energy balance care provided this care more often and more comprehensively. There were strong specialty differences, with pediatricians more likely (odds ratio, 1.78; 95% confidence interval, 1.26–2.51) and obstetrician/gynecologists less likely (odds ratio, 0.28; 95% confidence interval, 0.17–0.44) than others to provide energy balance care.

Conclusion.

PCPs' practices are not well organized for providing energy balance care. Further research is needed to understand PCP care-related specialty differences.

Efficacy of using physical activity mentors to increase the daily steps of older adults in the primary care setting: a pilot study

The purpose of this pilot study was to determine if using physical activity (PA) mentors has any additional impact on daily steps of older adults participating in the Maine in Motion (MIM) program in the primary care setting. Participants were randomly assigned to a MIM-only group (n = 14) or a MIM+ mentor group (n = 14). The MIM intervention lasted 6 months with follow-up at 12 months. Average age of participants was 64 ± 8.8 years and most participants had multiple chronic illnesses. At baseline, mean body mass index (BMI) was 32.2 ± 5.1 and average daily steps were 4,236 ± 2,266. Repeated-measures ANOVA revealed significant main effects for steps, F(2.324, 59.104) = 4.168, p = .015, but no main effects for group, F(1, 25) = 2.988, p = .096, or time-by-group interaction, F(2.324, 59.104) = 0.905, p = .151. All participants significantly increased daily steps over the course of the intervention, with MIM+ participants maintaining increases at follow-up. No significant findings were found for BMI.

Primary care physicians' prevention counseling with patients with multiple morbidity

The prevalence of multiple health conditions, or multiple morbidity (MM), is increasing. Providing medical care for adults with MM presents challenges, including balancing disease management with prevention. We conducted in-depth semistructured interviews with 12 primary care physicians to explore their perspectives on prevention counseling among patients with MM. Participants described the complex relationship between disease management and prevention, highlighted the importance of patient motivation, and discussed various strategies to promote receptivity to prevention recommendations. The perceived potential benefits of prevention recommendations encouraged physicians to persist with such counseling, despite challenges presented by visit time constraints, reimbursement procedures, and concerns over futility. Physicians recommended the development of alternate care delivery and reimbursement models to overcome challenges of the existing health care system and to meet the prevention needs of patients with MM. We explore the implications of these findings for maximizing the health and quality of life of adults with MM.

Underassessment of weight and weight management in patients with diabetes: one more reason in support of weight management advice

AIMS

The purpose of this study was to determine whether underassessment of weight affects weight management behaviors of overweight and obese individuals with diabetes and to determine whether weight management advice from health care professionals modifies the effect of underassessment of weight.

METHODS

Data (n=979) from the 2006 and 2008 National Health and Nutrition Examination Survey were analyzed. Multivariate logistic regression was used to identify factors associated with underassessment of weight, weight management behaviors, and receipt of weight management advice from health care professionals.

RESULTS

Underassessment of weight was common (26%). Men, overweight persons, Blacks and Hispanics were more likely to underassess their weight. Those who underassessed their weight were 53% less likely to report weight management behaviors, odds ratio 0.47 (95% CI=0.31-0.73). Weight management advice increased weight management behaviors among individuals who underassessed their weight, 3.49 (95% CI=1.70-7.18).

CONCLUSIONS

Underassessment of weight can negatively affect weight management behaviors of overweight and obese individuals with diabetes. Weight management advice from health care professionals is important, and can modify the effect of underassessment of weight on weight management behaviors in this high risk group.

The reporting of previous lifestyle counseling by persons at high risk of Type 2 diabetes

OBJECTIVE

To assess (i) whether the reporting of counseling previously received is associated with high-risk individuals' agreement to participate in lifestyle intervention, (ii) whether the reporting of previous counseling differed within such a high-risk group, and (iii) the associations between lifestyles and previous lifestyle counseling.

METHODS

Cross-sectional data were drawn from 10149 adults at high risk of Type 2 diabetes, who were participating in a Finnish national diabetes prevention project (FIN-D2D). Bivariate analysis and multivariate logistic regression were used.

RESULTS

In relation to the reporting of previous counseling, no difference was found between persons who had agreed and persons who had not agreed to participate in the lifestyle intervention. Persons who were more educated or who had dyslipidemia or diabetes were more likely than the others to report previous counseling. A generally healthy lifestyle, or certain health behaviors (being a non-smoker or eating large amounts of fruit and vegetables) may make the reporting of previous counseling more likely.

CONCLUSION

The results raise questions about the amount and quality of the previously received lifestyle counseling.

PRACTICE IMPLICATIONS

There is a need for sustainable lifestyle counseling structures, within vigorously implemented diabetes prevention projects, if long-lasting lifestyle changes are to be achieved.

Association between adherence to physical activity guidelines and health-related quality of life among individuals with physician-diagnosed arthritis

PURPOSE

To examine the association between adherence to physical activity guidelines and health-related quality of life (HRQOL) among individuals with arthritis.

METHODS

A cross-sectional sample with 33,071 US adults, 45 years or older with physician-diagnosed arthritis was obtained from 2007 Behavioral Risk Factor Surveillance System survey. We conducted negative binomial regression analysis to examine HRQOL as a function of adherence to physical activity guidelines controlling for physicians' recommendations for physical activity, age, sex, race, education, marital status, employment, annual income, health insurance, personal physician, emotional support, body mass index, activity limitations, health status, and co-morbidities based on Behavioral Model of Health Services Utilization.

RESULTS

Descriptive statistics showed that 60% adults with arthritis did not adhere to physical activity guidelines, mean physically and mentally unhealthy days were 7.7 and 4.4 days, respectively. Results from negative binomial regression indicated that individuals who did not adhere to physical activity guidelines had 1.14 days more physically unhealthy days and 1.12 days more mentally unhealthy days than those who adhered controlling for covariates.

CONCLUSIONS

Adherence to physical activity is important to improve HRQOL for individuals with arthritis. However, adherence is low among this population. Interventions are required to engage individuals with arthritis in physical activity.

Physician advice on exercise and diet in a U.S. sample of obese Mexican-American adults

PURPOSE

To document the prevalence of obese Mexican-Americans never advised by health professionals regarding exercise and diet, and to determine risk factors for no advice.

METHODS

Data came from 1787 obese Mexican-American adults (body mass index ≥30; age ≥18 years) in the Medical Expenditure Panel Survey. The survey included self-reported receipt of health care provider advice on exercise and diet as well as sociodemographic, health-related, and provider-related factors. Multivariable logistic regression models were performed separately for advice regarding exercise and advice regarding diet.

RESULTS

Overall, 45% of respondents reported that they had never received advice from a doctor or health care professional to exercise more, and 52% reported that they have received advice to eat fewer higher-fat/high-cholesterol foods. Men, nonmarried respondents, lower-educated respondents, those who preferred to speak Spanish at home, and those without comorbid chronic conditions were less likely to receive advice.

DISCUSSION

Results suggest that obese Mexican-Americans are insufficiently advised by health care providers regarding exercise and diet. Given the seriousness of obesity-related health risks and the increasing prevalence of overweight status and obesity among Mexican-Americans, it is vital that providers are involved in finding ways to effectively educate and/or treat overweight patients.

A randomized controlled trial of communication training with primary care providers to improve patient-centeredness and health risk communication

OBJECTIVE

to determine the efficacy and effectiveness of training to improve primary care providers' patient-centered communication skills and proficiency in discussing their patients' health risks.

METHODS

twenty-eight primary care providers participated in a baseline simulated patient interaction and were subsequently randomized into intervention and control groups. Intervention providers participated in training focused on patient-centered communication about behavioral risk factors. Immediate efficacy of training was evaluated by comparing the two groups. Over the next 3 years, all providers participated in two more sets of interactions with patients. Longer term effectiveness was assessed using the interaction data collected at 6 and 18 months post-training.

RESULTS

The intervention providers significantly improved in patient-centered communication and communication proficiencies immediately post-training and at both follow-up time points.

CONCLUSIONS

this study suggests that the brief training produced significant and large differences in the intervention group providers which persisted 2 years after the training.

PRACTICE IMPLICATIONS

the results of this study suggest that primary care providers can be trained to achieve and maintain gains in patient-centered communication, communication skills and discussion of adverse childhood events as root causes of chronic disease.

Disparities in hypertension control advice according to smoking status

OBJECTIVES

Hypertension is the most common modifiable cardiovascular risk factor. Blood pressure (BP) reduction, particularly among smokers, is highly effective at preventing cardiovascular diseases. We examined the association between patient smoking status and hypertension management advice.

METHODS

Adults who participated in the 2007 Behavioral Risk Factor Surveillance System with self-reported hypertension were examined (n=51,063). Multivariable logistic regression analysis controlling for age, gender, race/ethnicity, education, marital status, insurance status, body mass index, alcohol use, self-reported general health and survey design were conducted to examine the association between smoking status (never, former, or current) and receipt of hypertension control advice.

RESULTS

After controlling for potential confounders, being a current smoker was significantly associated with lower odds of receiving advice to lower salt intake (Adjusted Odds Ratio, AOR, 0.91 [95% confidence interval=0.84-0.99]), exercise (AOR 0.89 [0.80-0.98]), and to take hypertensive medication (AOR 0.80 [0.66-0.98]) compared to never smokers. However, hypertensive smokers had greater odds of receiving advice to reduce alcohol consumption (AOR 1.23 [1.10-1.45]).

CONCLUSIONS

Although healthcare providers are in an optimal position to provide patient education to improve BP control, hypertensive smokers may be less likely to receive important BP control lifestyle modification messages from their healthcare provider than non-smokers.

Young adult Ecstasy users who forego necessary medical care: a fairly common occurrence with important health implications

This study examines the practice of foregoing necessary medical care in a population of young adult Ecstasy users. The objectives are to (1) investigate how the failure to receive needed medical care is related to drug-related outcomes, and (2) identify factors that are associated with receiving versus foregoing needed medical care. Face-to-face, computer-assisted, structured interviews were conducted with 283 active young adult Ecstasy users in Atlanta, Georgia between August 2002 and October 2007. Study participants were recruited using a targeted sampling approach. Results indicated that almost one-third of the young adult Ecstasy users interviewed did not receive the medical care that they needed during the preceding year. Foregoing such care was associated with a variety of adverse drug-related outcomes, including experiencing a greater number of negative effects from using Ecstasy, experiencing a larger number of drug dependency symptoms, a greater likelihood of ever having binged on Ecstasy, and a greater likelihood of being classified as a "high end" polydrug abuser. Several factors were found to be associated with a greater tendency not to receive the medical care they needed, including race (not being African American), educational attainment (having completed at least high school), self-identification as belonging to the lowest socioeconomic status grouping, low self-esteem, and having experienced sexual abuse during one's formative years.

Limited English proficiency is a barrier to receipt of advice about physical activity and diet among Hispanics with chronic diseases in the United States

The prevalence of obesity, diabetes, and cardiovascular disease is reaching epidemic proportions among Hispanics in the United States. Health care providers play an important role in motivating patients to make healthful lifestyle changes to reduce the burden of such conditions. Data from the US 2000 National Health Interview Survey was analyzed to determine differences in report of physician-provided physical activity and/or dietary advice by level of English proficiency among obese Hispanics or those who reported having diabetes or cardiovascular disease and who contacted a physician during the past year (n=1,186). Only one third of the sample reported receiving advice to increase their physical activity or to improve their dietary habits; one fifth reported receipt of advice about both. English-proficient Hispanics were about 50% more likely to report receiving advice on physical activity (adjusted odd ratio [AOR]=1.5; 95% confidence interval [CI]: 1.1 to 2.1), diet (AOR=1.5; 95% CI: 1.1 to 2.2) or both (AOR=1.6; 95% CI: 1.1 to 2.3), as compared with limited English-proficient Hispanics, after controlling for health insurance coverage and number of visits to a physician during the last year. Sex, age, region of residence, level of education, annual family income, and smoking status were not significantly associated with receiving physical activity and/or dietary advice. In order to address racial health disparities, and lower the burden of chronic illness, culturally sensitive strategies must be implemented to enhance delivery of effective health-promotion messages by physicians, particularly among at-risk communities.

African Americans and Whites Are Equally Appropriate to be Considered for Total Joint Arthroplasty

Objective.

Ethnic disparities in the use of total joint arthroplasty (TJA) may be attributed to differences in the clinical appropriateness to undergo TJA. We sought to determine if racial differences in clinical appropriateness for surgery existed among a sample of primary care clinic patients with moderately to severely symptomatic knee or hip osteoarthritis (OA).

Methods.

We used the cross-sectional data of 684 patients who are potential candidates for TJA. Using a validated TJA appropriateness algorithm, an appropriateness factor was derived using the following variables: age (50–70 or > 70 yrs), Charlson comorbidity (≤ 1 or > 1), Western Ontario and McMaster Universities OA Index (WOMAC) pain and physical function, and adequacy of previous medical management. We used logistic regression to estimate the association of race with the dichotomous outcome of clinical appropriateness for TJA consideration.

Results.

Sample consisted of 425 (62%) whites and 260 (38%) African Americans; 532 (78%) had knee OA and 153 (22%) had hip OA. The mean age was 64 ± 9 years and the mean body mass index was 33.6 ± 8 kg/m2. The mean overall WOMAC score was 56 ± 14 (range 30–96), suggesting moderately severe OA. There were no significant racial group differences (p = 0.3) in the proportions of those deemed clinically appropriate for TJA. After controlling for potential confounders, race was not a predictor of clinical appropriateness for TJA (odds ratio 1.2, 95% confidence interval 0.8–1.8, p = 0.3).

Conclusion.

African Americans and whites were equally appropriate to be considered for TJA.

Exercise prescription for chronic back or neck pain: who prescribes it? who gets it? What is prescribed?

OBJECTIVE

To describe exercise prescription in routine clinical practice for individuals with chronic back or neck pain because, although current practice guidelines promote exercise for chronic back and neck pain, little is known about exercise prescription in routine care.

METHODS

We conducted a computer-assisted telephone survey of a representative sample of individuals (n = 684) with chronic back or neck pain who saw a physician, chiropractor, and/or physical therapist (PT) in the past 12 months. Individuals were asked about whether they were prescribed exercise, the amount of supervision received, and the type, duration, and frequency of the prescribed exercise. Descriptive and multivariable regression analyses were conducted.

RESULTS

Of the 684 subjects, 48% were prescribed exercise. Of those prescribed exercise, 46% received the prescription from a PT, 29% from a physician, 21% from a chiropractor, and 4% from other. In multivariable analyses, seeing a PT or a chiropractor were the strongest predictors of exercise prescription. The likelihood of exercise prescription was increased in women, those with higher education, and those receiving worker's compensation. PTs were more likely to provide supervision and prescribe strengthening exercises compared with physicians and chiropractors, and were more likely to prescribe stretching exercises compared with physicians.

CONCLUSION

Our findings suggest that exercise is being underutilized as a treatment for chronic back and neck pain and, to some extent, that the amount of supervision and types of exercises prescribed do not follow current practice guidelines. Exercise prescription provided by PTs appears to be most in line with current guidelines.

Comparison of body perceptions between obese primary care patients and physicians: implications for practice

OBJECTIVE

To compare the body image and weight perceptions of primary care patients and their physicians as a first step toward identifying a potential tool to aid physician-patient communication.

METHODS

Patients with a body mass index (BMI)> or =30 (n=456, 66% female) completed body image and weight status measures after office visits; physicians (n=29) rated the body figures and weight status of these same patients after office visits.

RESULTS

Controlling for BMI, female patients and their physicians showed little or no difference in body figure selection or weight status classification, whereas male patients were significantly less likely than their physicians to self-identify with larger body figures (z=3.74, p<0.01) and to classify themselves as obese or very obese (z=4.83, p<0.0001).

CONCLUSION

Findings reveal that physicians and female patients have generally concordant views of the patient's body size and weight status, whereas male patients perceive themselves to be smaller than do their physicians. The discrepancy between male patient and physician views is especially evident at increasingly larger body figure/weight status categories.

PRACTICE IMPLICATIONS

When counseling male patients on weight loss, it could be helpful to assess body image and use this information to raise patient awareness of their size and to facilitate communication about weight.

Primary prevention of overweight and obesity: an analysis of national survey data

BACKGROUND

Obesity is rapidly approaching tobacco as the leading cause of preventable morbidity and mortality. Health care providers have the opportunity to address this through primary prevention strategies.

OBJECTIVE

To assess whether health care professionals provide primary prevention for overweight and obesity by examining the percentage of healthy-weight (body mass index [BMI] = 18.5-24.9 kg/m(2)) individuals who report being advised to maintain a healthy weight.

DESIGN

Cross-sectional analysis of the 2003 Behavioral Risk Factor Surveillance Survey data.

PARTICIPANTS

Noninstitutionalized U.S. adults >18 years of age.

RESULTS

Among healthy BMI respondents, only 2.6% reported receiving primary prevention. Logistic regression analyses yielded that healthy-weight adults receiving primary prevention were more likely to report: being 18-49 years of age, annual household incomes <$35,000, having at least 1 comorbidity, having a health care provider, changed eating habits to include less fat or fewer calories, and using physical activity to maintain or lose weight. Men were also more likely to receive primary prevention.

CONCLUSIONS

Only a very small proportion of healthy-weight adults received primary prevention, which suggests that physicians are missing opportunities to help address the epidemic of adult obesity in the US.

Cancer prevention in primary care: predictors of patient counseling across four risk behaviors over 24 months

OBJECTIVE

Rates of preventive counseling remain below national guidelines. We explored physician and patient predictors of preventive counseling across multiple cancer risk behaviors in at-risk primary care patients.

METHODS

We surveyed 3557 patients, with at least one of four cancer risk behaviors: smoking, diet, sun exposure, and/or mammography screening, at baseline and 24 months. Patients reported receipt of 4A's (Ask, Advise, Assist, Arrange follow-up); responses were weighted and combined to reflect more thorough counseling (Ask=1, Advise=2, Assist=3, Arrange=4, score range 0-10) for each target behavior. A series of linear-regression models, controlling for office clustering, examined patient, physician and other situational predictors at 24 months.

RESULTS

Risk behavior topics were brought up more often for mammography (90%) and smoking (79%) than diet (56%) and sun protection (30%). Assisting and Arranging follow-up were reported at low frequencies across all behaviors. More thorough counseling for all behaviors was associated with multiple visits and higher satisfaction with care. Prior counseling predicted further counseling on all behaviors except smoking, which was already at high levels. Other predictors varied by risk behavior.

CONCLUSIONS

More thorough risk behavior counseling can be delivered opportunistically across multiple visits; doing so is associated with more satisfaction with care.

Are United States adults with coronary heart disease meeting physical activity recommendations?

Cardiovascular disease remains the leading cause of death in the United States. The benefits of physical activity in reducing the risk for cardiovascular disease have led to recommendations that patients with heart disease increase their levels of physical activity. This study was conducted to investigate the degree of compliance with national and/or American Heart Association and American College of Cardiology guidelines for physical activity in United States adults with coronary heart disease (CHD) in comparison with subjects without CHD using data from the 2005 Behavioral Risk Factor Surveillance System (BRFSS). Information on CHD or physical activity was self-reported. A total of 297,145 participants aged > or =18 years were included in the analyses. The age-standardized prevalence and the odds ratios for meeting total, moderate, or vigorous physical activity recommendations were calculated. Patients with CHD participated less in physical activity at recommended levels than those without CHD (40%, 32%, and 22% vs 49%, 37%, and 29%, respectively, for meeting total, moderate, and vigorous physical activity recommendations, p <0.01 for all). The unadjusted odds ratios for adults with CHD who met total, moderate, and vigorous physical activity were 0.61 (95% confidence interval 0.58 to 0.65), 0.76 (95% confidence interval 0.72 to 0.80), and 0.45 (95% confidence interval 0.42 to 0.49), respectively. These odds ratios were attenuated slightly but remained significant even after multivariate adjustment. In conclusion, the findings of this study demonstrate that patients with CHD are less likely to comply with physical activity recommendations than subjects without CHD. Intensive physical activity counseling is needed for patients with CHD to increase their physical activity levels if no contraindications to increased physical activity exist.

Lifestyle modification advice for lowering or controlling high blood pressure: who's getting it?

Lifestyle modifications (LSMs) are important in hypertension management. Using data from a population-based sample of hypertensive adults (N=28,457), the authors examined variations in reports of receipt of LSM advice by patient characteristics. Most adults (90.3%) with known hypertension reported receiving some type of advice. Exercise advice was reported most frequently (74.6%), followed by advice to reduce salt intake (69.3%), change eating habits (61.9%), and reduce alcohol intake (43.5%). Compared with adults aged 60 years or older, persons aged 18 to 39 years were more likely to report receipt of advice (odds ratio [OR], 1.42; 95% confidence interval [CI], 1.11-1.81). Overweight persons (OR, 1.64; 95% CI, 1.40-1.93) and obese persons (OR, 2.75; 95% CI, 2.28-3.31) were more likely to report receipt of advice. Persons receiving antihypertensive medication were also more likely to report receiving advice (OR, 2.35; 95% CI, 1.98-2.81). This study demonstrates that older persons, persons not taking antihypertensive medication, and individuals who are not overweight or obese are less likely to report receiving LSM advice.

Health service utilization by Ethiopian immigrants and refugees in Toronto

The purpose of this study was to examine the health service utilization patterns of Ethiopian immigrants and refugees in a random sample of 342 adults residing in Toronto. The results suggested that 85% of the study participants used one or more type of health services, most often from a family physician. However, only 12.5% of them with a mental disorder received services from formal healthcare providers, mainly family physicians. While the presence of somatic symptoms was significantly associated with increased use of healthcare (p < 0.05), having a mental disorder was associated with lower rate of health service use (p < 0.05). These findings suggest that family physicians could play important role in identifying and treating Ethiopian clients who present with somatic symptoms, as these symptoms may reflect mental health problems. Further research is necessary to determine the reasons for the low rates of mental health services use in this population.

Physical activity advice in the primary care setting: results of a population study in New Zealand

OBJECTIVES

To determine the prevalence of physical activity advice, including the Green Prescription (a physical activity scripting scheme), given in the primary care setting, and the characteristics of New Zealanders who receive such advice.

METHOD

Questions from a 2003 national postal survey (n = 8,291), 'Obstacles to Action', were examined. The survey was designed to identify population segments to target for physical activity interventions. Binary logistic regression was used to examine independent factors associated with receiving a physician or practice nurse recommendation to increase physical activity and receiving a Green Prescription.

RESULTS

Overall, 13.3% of the sample reported receiving physical activity advice while 3.0% reported receiving a Green Prescription from their general practitioner or practice nurse in the last year. Those more likely to receive physical activity advice were Maori or Pacific, overweight or obese, sedentary, or suffering chronic disease. Results were similar for Green Prescription advice. When controlling for these and other demographics, physical inactivity was not related to the odds of receiving a Green Prescription.

CONCLUSIONS

One out of every eight New Zealanders reported being given general physical activity advice in the primary care setting. While the physically inactive but otherwise healthy were not specifically targeted, the Green Prescription was more likely to be given on the basis of existing chronic conditions related to physical inactivity and other high-risk populations.

IMPLICATIONS

Primary care settings provide an important opportunity to promote physical activity for New Zealand adults. While those most at risk are more likely to receive such advice, there are many more that may benefit.

Participants' willingness to consume soy foods for lowering cholesterol and receive counselling on cardiovascular disease by nutrition professionals

Objectives

To determine if participants would be interested in consuming soy foods to lower cholesterol in primary and secondary prevention of heart disease, and to identify the role physicians and registered dietitians have in providing dietary advice, about soy foods or other foods, for participants with elevated cholesterol.

Methodology

Qualitative data from 12 focus groups were gathered from a convenience sample of 74 adults, aged 18–91 years, with and without high cholesterol (total cholesterol >200 mg dl−1). Participants were recruited from Minneapolis/St. Paul mainstream and natural foods grocery stores. Focus group interviews were taped and transcribed verbatim. Common themes were identified, coded and compared using NVivo computer software.

Results

Participants believed diet, lifestyle and genetics were the cause of high cholesterol and cardiovascular disease (CVD). Few participants were aware of the Food and Drug Administration health claim for soy protein, yet many were willing to consume soy as part of lifestyle modification to prevent CVD. They reported preferring food and exercise over medication to treat high cholesterol. Few participants had ever received dietary advice from physicians on treating high cholesterol or CVD, and most doubted the accuracy of such advice. They believed registered dietitians were the most credible source of nutrition counselling and expressed an interest in physician referrals to dietitians.

Conclusions

A collaboration and referral system between physicians and registered dietitians could increase CVD patients' consumption of soy foods as a means potentially leading to a reduced risk of heart disease in participants.

Mental health service utilization by Ethiopian immigrants and refugees in Toronto

The purpose of this study was to examine the mental health service utilization patterns of Ethiopians in Toronto. A cross-sectional epidemiological survey of 342 randomly selected adults was conducted, based on a conceptual model of healthcare utilization suggested by Anderson and Newman. The results suggested that 5% of the respondents sought mental health services from healthcare professionals and 8% consulted nonhealthcare professionals. Although Ethiopians' utilization rate of mental health services did not greatly differ from the rates of the general population of Ontario (6%), only a small proportion (12.5%) of Ethiopians with mental disorders used services from healthcare professionals, mostly family physicians. The data also suggested that Ethiopians were more likely to consult traditional healers than healthcare professionals for mental health problems (18.8% vs. 12.5%). In multivariate logistic regression analyses, while the number of somatic symptoms experienced was positively associated with increased mental healthcare utilization (OR = 1.515, p < 0.05), having a mental disorder was associated with decreased mental healthcare utilization (OR = 0.784, p < 0.01). Our findings have important implications for mental health services. On the one hand, the findings suggest that somatic symptoms could lead to increased use of mental health services, particularly family physicians' services. On the other hand, the data suggested that although the mental healthcare needs of Ethiopians are high, they use fewer mental health services from healthcare professionals. It would seem that family physicians could play important role in identifying and treating Ethiopian clients with somatic symptoms, as these symptoms may reflect mental disorder.

Weight-related perceptions among patients and physicians: how well do physicians judge patients' motivation to lose weight?

BACKGROUND

Prior studies suggest that patients and physicians have different perceptions and expectations surrounding weight; however, few studies have directly compared patients' and physicians' perspectives.

OBJECTIVES

(1) To measure the extent to which obese patients and their physicians have discrepant weight-related perceptions, and (2) to explore patient and physician characteristics that may influence patient-physician discrepancy in motivation to lose weight.

DESIGN AND PARTICIPANTS

Four hundred and fifty-six obese patients (302 females; mean age = 55.1 years; mean BMI = 37.9) and their 28 primary care physicians (22 males, mean age = 44.1 years) from nonmetropolitan practices completed an anonymous survey after an office visit.

MEASURES

Weight-related perceptions included perceived weight status, health impact of weight, 1-year weight loss expectations, and motivation to lose weight. Correlates included patient and physician sex, age, and BMI; physicians' reported frequency, perceived patient preference, and confidence for weight counseling; and practice characteristics (e.g., years in practice).

RESULTS

Physicians assigned patients to heavier descriptive weight categories and reported a worse health impact than patients perceived for themselves, whereas patients believed they could lose more weight and reported a higher motivation to lose weight than their physicians perceived for patients (P < .001). Physicians who believed patients preferred to discuss weight more often (P = .001) and who saw more patients per week (P = .04) were less likely to underestimate patient motivation.

CONCLUSIONS

Patients reported more optimistic weight-related perceptions and expectations than their physicians. Further research is needed to determine how these patient-physician discrepancies may influence weight loss counseling in primary care.

Variations in physicians' advice for managing hypertension in women: a study using NHANES III

OBJECTIVE

To examine the pattern of physician advice-giving to individuals with hypertension and to determine if advice-giving and adherence to advice vary by race.

METHODS

Frequency of physician recommendations and patient adherence to such advice were analyzed using data from the Third National Health and Nutrition Examination Survey conducted from 1988 to 1994. A total of 2066 women were included in the study.

RESULTS

The frequency of advice-giving and patient adherence to that advice varied as a function of the type of advice dispensed. Physician advice-giving and patient adherence also varied as a function of race; compared to Black women, White women were 60% less likely [OR (95% CI): 0.41 (0.25, 0.65)] to be told to take prescribed medicines and 56% less likely [OR (95% CI): 0.44 (0.26, 0.76)] to be told to exercise. Regarding patient adherence, compared to Black women, White women were 37% less likely [OR (95% CI): 0.63 (0.44, 0.91)] to use prescribed medicines, 59% less likely [OR (95% CI): 0.41 (0.26, 0.66)] to report reducing use of salt/sodium, and among overweight women, 50% less likely [OR (95% CI): 0.50 (0.31, 0.81)] to report efforts to control/lose weight.

CONCLUSIONS

The variability of physician advice and patient adherence as a function of race warrants further study.

Koreans' use of medical services in Seoul, Korea and California

This study assessed the types of health care services used by Korean immigrants, and differences in use between different countries, genders, health insurance status, acculturation status, and cardiovascular risk. Participant selection used probability sampling to represent the adult populations of California, United States, and Seoul, Republic of Korea. A telephone survey was administered to 2,830 adult Korean-Californians and 500 adult Koreans living in Seoul. Female gender was significantly associated with higher use of outpatient services, ER usage, and hospitalization. Californian residence was significantly associated with higher outpatient usage and lower hospitalization rates. Health insurance was associated with higher allopathic health care utilization, and lower traditional health care usage, and acculturation with lower traditional health care usage. Higher self-reported cardiac risk factors were associated with lower allopathic and higher traditional health care. This suggests barriers to allopathic health care, but not traditional health care, for Koreans living in California without health insurance.
