          Abstract

          Despite the increased emphasis on obesity and diet-related diseases, nutrition education remains lacking in many internal medicine training programs. We evaluated the attitudes, self-perceived proficiency, and knowledge related to clinical nutrition among a cohort of internal medicine interns.

          Excess deaths associated with underweight, overweight, and obesity.

          Katherine Flegal (2005)
          As the prevalence of obesity increases in the United States, concern over the association of body weight with excess mortality has also increased. To estimate deaths associated with underweight (body mass index [BMI] or =30) in the United States in 2000. We estimated relative risks of mortality associated with different levels of BMI (calculated as weight in kilograms divided by the square of height in meters) from the nationally representative National Health and Nutrition Examination Survey (NHANES) I (1971-1975) and NHANES II (1976-1980), with follow-up through 1992, and from NHANES III (1988-1994), with follow-up through 2000. These relative risks were applied to the distribution of BMI and other covariates from NHANES 1999-2002 to estimate attributable fractions and number of excess deaths, adjusted for confounding factors and for effect modification by age. Number of excess deaths in 2000 associated with given BMI levels. Relative to the normal weight category (BMI 18.5 to or =30) was associated with 111,909 excess deaths (95% confidence interval [CI], 53,754-170,064) and underweight with 33,746 excess deaths (95% CI, 15,726-51,766). Overweight was not associated with excess mortality (-86,094 deaths; 95% CI, -161,223 to -10,966). The relative risks of mortality associated with obesity were lower in NHANES II and NHANES III than in NHANES I. Underweight and obesity, particularly higher levels of obesity, were associated with increased mortality relative to the normal weight category. The impact of obesity on mortality may have decreased over time, perhaps because of improvements in public health and medical care. These findings are consistent with the increases in life expectancy in the United States and the declining mortality rates from ischemic heart disease.

            Barriers to providing nutrition counseling by physicians: a survey of primary care practitioners.

            R Kushner (1995)
            Previous surveys have shown that there is a disparity between physicians' beliefs about the importance of diet and nutrition in health maintenance and disease prevention and the actual delivery of nutrition counseling. The primary objective of this study was to assess the current attitudes, practice behavior, and barriers to the delivery of nutrition counseling by primary care physicians. A random-sample-mailed questionnaire was sent to 2,250 primary care physicians selected from the AMA masterfile from general practice, internal medicine, and pediatrics, representing self-employed, group, hospital, and HMO practices. Participants were stratified by age, gender, geographical region, and present employment. The main outcome measures were to determine time spent by physicians providing and percentage of patients receiving dietary counseling and to identify barriers to the delivery of nutrition counseling. A 49% response rate (n = 1,103) was obtained. Results are presented for the 1,030 physicians (70% private practice) with complete data. Over two-thirds of physicians provide dietary counseling to 40% or less of patients and spend 5 or fewer min discussing dietary changes. Despite this pattern, nearly three-quarters of respondents feel that dietary counseling is important and is the responsibility of the physician. Ranking of perceived barriers to delivery of dietary counseling were lack of time, patient noncompliance, inadequate teaching materials, lack of counseling, training, lack of knowledge, inadequate reimbursement, and low physician confidence. This survey suggests that multiple barriers exist that prevent the primary care practitioner from providing dietary counseling. A multifaceted approach will be needed to change physician counseling behavior.

              Are physicians equipped to address the obesity epidemic? Knowledge and attitudes of internal medicine residents.

              Jason P. Block, Karen B DeSalvo, William P. Fisher (2003)
              To analyze whether internists are suited for their role in treating the growing numbers of obese patients, we surveyed residents about their knowledge and attitudes regarding obesity. Previous assessments have not analyzed familiarity with obesity measurement tools or the correlation between knowledge and attitudes. We administered a survey to 87 internal medicine residents in two urban, university-based residency programs. Almost all respondents understood the medical consequences of obesity, but 60% did not know the minimum BMI for diagnosing obesity, 69% did not recognize waist circumference as a reasonable measure of obesity, and 39% incorrectly reported their own BMI. Although nearly all respondents agreed that treating obesity was important, only 30% reported treatment success. Forty-four percent felt qualified to treat obese patients, and 31% reported treatment to be futile. Knowledge and attitudes were not correlated. Rasch analysis of knowledge and attitude subscales showed satisfactory model fit and item reliability of at least 0.96. Despite solid knowledge of the comorbid conditions associated with obesity, residents have a poor grasp of the tools necessary to identify obesity. They also have negative opinions about their skills for treating obese patients. Residency training not only must improve knowledge of obesity measurement tools but also must address physicians' negative attitudes toward obesity treatment.
