Height, weight, and body mass index of American Indian schoolchildren, 1990–1991

Objective To describe the current height and weight status of American Indian children who live on or near Indian reservations nationwide.Subjects 9,464 American Indian schoolchildren aged 5 through 18 years.Statistical analyses performed Data for height, weight, and body mass index of the schoolchildren were compared with two national reference data sets, the second National Health and Nutrition Examination Survey (NHANES II) and the Mexican-American population of the Hispanic Health and Nutrition Examination Survey (HHANES-MA).Results The three populations were similar in height, but the American Indian children weighed more, although not at a statistically significant level, and had a statistically significant higher body mass index than the NHANES II reference population for nearly every age and sex group. The overall prevalence of overweight in the American Indian children (exceeding the 85th percentile of the reference population) was 39.3% compared with the NHANES II population and 28.6% compared with the HHANES-MA population. The overall prevalence of underweight in the American Indian sample was substantially less than the expected 15% compared with either the NHANES II or HHANES-MA population.Applications/conclusions Overweight is much more prevalent in American Indian children than among other children in the United States at all ages and in both sexes. This may have important implications for chronic disease risk and emphasizes the need for targeting obesity prevention efforts to American Indian children.     

Excess mortality in giant cell arteritis

A 13-year departmental sample of 34 patients with definite (biopsy-verified) giant cell arteritis (GCA) was reviewed. The mortality of this material was compared to sex-, age- and time-specific death rates in the Danish population. The standardized mortality ratio (SMR) was 1.8 (95% confidence limits, 1.1-2.8). During the same period 146 patients with probable (not biopsied, but clinically diagnosed in the department) GCA and 85 cases of possible (diagnosed and treated before admission) GCA had been admitted to the department. Those two groups did not differ from the biopsy-verified group with respect to SMR, sex distribution or age. In the group of patients with department-diagnosed GCA (definite + probable = 180 patients), the 95% confidence interval for the SMR of the women included 1.0. In all other subgroups there was a significant excess mortality. Excess mortality has been found in two of seven previous studies on survival in GCA. The prevailing opinion that steroid-treated GCA does not affect the life expectancy of patients is probably not correct.     

Cold lesion of a vertebral angioma with Tc-99m-labeled monoclonal antibodies against granulocytes.

Antigranulocyte immunoscintigraphy is indicated for diagnostic imaging to determine the location and extent of infection. We present a case of a focal cold lesion in a vertebra of a patient thought to have a septic focal lesion. Whole-body scanning and dorsal spine SPECT revealed no focal increased uptake. CT and MR studies revealed the presence of a vertebral angioma. Conditions associated with a defect of uptake in immunoscintigraphy are discussed.     

Maternal Acceptability of a Dietary Intervention Designed to Lower Children''s Intake of Saturated Fat and Cholesterol: The Dietary Intervention Study in Children (DISC)

Objective This report examined the acceptability to mothers of a dietary educational and behavioral intervention for preadolescent children with elevated levels of serum low-density lipoprotein cholesterol (LDL-C) who were enrolled in the Dietary Intervention Study in Children (DISC).Design DISC is a randomized, controlled clinical trial. Subjects were randomly assigned to either an intervention or usual-care (control) group.Subjects/setting To be eligible for the study, participants were required to have the average of 2 fasting LDL-C values fall between the 80th and 98th sex-specific percentiles. Three hundred thirty-four 8- to 10-year-old children and their families were randomly assigned to an intervention group, and 329 were assigned to a usual-care (control) group. This study examined data from 232 subjects in the intervention group. Data were collected at 6 intervention sites around the United States.Intervention Those assigned to the intervention group participated in a multidisciplinary dietary intervention that included a series of group and individual sessions over a 3-year period. Children and their caretakers were taught to follow a nutritionally adequate diet that was low in total fat, saturated fat, and cholesterol and high in polyunsaturated fat.Main outcome measures Three nonconsecutive 24-hour diet recalls were collected at baseline and at 1 year by trained and certified dietitians. A questionnaire designed to assess diet acceptability was administered at months 4, 8, 11, and 15. Demographic measures were collected at the onset of the study.Statistical analysis performed Statistical procedures included factor analysis and regression analysis.Results Regression analysis suggested that perceived effectiveness of the dietary intervention and mothers’ having few concerns about disadvantages of the diet were significantly related to higher overall fat intake in children in one-parent families. Maternal willingness to implement the diet was significantly related to lower saturated fat intake.Applications/conclusions In attempts to change eating behavior of children, interest and cooperation of the parents are essential to achieving successful results. These analyses further suggest that maternal acceptability translates into willingness to implement the diet and may facilitate changes that are associated with reduced saturated fat intake in children.

The ‘Age+5’ Rule: Comparisons of Dietary Fiber Intake Among 4- to 10-Year-Old Children

Objective To determine children's sources of dietary fiber and to identify the food group choices made by those who met the “age+5” rule, which recommends that children daily consume an amount of fiber that is equal to their age plus an additional 5 g fiber.

Design This study used 24-hour dietary recalls and 1-day food records to assess the nutrient intake and food group choices of children who did and did not meet the recommendations of the age+5 rule.

Subjects The 1989-1991 US Department of Agriculture Continuing Survey of Food Intakes by Individuals provided the study sample of 603 children between the ages of 4 and 6 years and 782 children between the ages of 7 and 10 years.

Statistical analyses Differences in nutrient and food group intakes between age categories were determined by t tests.

Results Only 45% of 4- to 6-year-olds and 32% of 7- to 10-year-olds consumed adequate fiber to meet the age+5 rule. Those who met the age+5 rule did so by consuming significantly more high- and low-fiber breads and cereals, fruits, vegetables, legumes, nuts, and seeds. Children with low fiber intakes had significantly higher energy-adjusted intakes of fat and cholesterol, whereas those who met the age+5 rule had significantly higher energy-adjusted intakes of dietary fiber, vitamins A and E, folate, magnesium, and iron.

Applications The majority of the children had low intakes of dietary fiber, suggesting that they are at risk for future chronic disease. Parents and school foodservice personnel should strive to offer fiber-rich foods to children so their acceptance and consumption of them will be increased. J Am Diet Assoc. 1998;98:1418-1423.     

Evaluating the cost‐effectiveness of cancer patient navigation programs: Conceptual and practical issues

Patient navigators—individuals who assist patients through the healthcare system to improve access to and understanding of their health and healthcare—are increasingly used for underserved individuals at risk for or with cancer. Navigation programs can improve access, but it is unclear whether they improve the efficiency and efficacy of cancer diagnostic and therapeutic services at a reasonable cost, such that they would be considered cost‐effective. In the current study, the authors outline a conceptual model for evaluating the cost‐effectiveness of cancer navigation programs. They describe how this model is being applied to the Patient Navigation Research Program, a multicenter study supported by the National Cancer Institute's Center to Reduce Cancer Health Disparities. The Patient Navigation Research Program is testing navigation interventions that aim to reduce time to delivery of quality cancer care (noncancer resolution or cancer diagnosis and treatment) after identification of a screening abnormality. Examples of challenges to evaluating cost‐effectiveness of navigation programs include the heterogeneity of navigation programs, the sometimes distant relation between navigation programs and outcome of interest (eg, improving access to prompt diagnostic resolution and life‐years gained), and accounting for factors in underserved populations that may influence both access to services and outcomes. In this article, the authors discuss several strategies for addressing these barriers. Evaluating the costs and impact of navigation will require some novel methods, but will be critical in recommendations concerning dissemination of navigation programs.

Nutritional status of Chinese-, Korean-, and Japanese-American elderly

Objective To examine the nutritional status of three major subgroups of Asian-American elderly.

Subjects The sample consisted of 169 Chinese, 90 Korean, and 50 Japanese elderly who lived in five apartment buildings for senior citizens in Chicago, Ill.

Main outcome measures Twenty-four-hour dietary recalls were used to evaluate dietary intake. Anthropometric measures of height, weight, and triceps skinfold thickness were also obtained.

Results Many Asian-American elderly consume an inadequate amount of dietary calcium. A large percentage of Korean elderly also consume inadequate amounts of protein and vitamins A and C. Underweight was more common than obesity among these ethnic elderly groups.

Applications The information in this article provides valuable data to the Asian-American community for program planning as well as to health providers who work with individual Asian-American elderly to meet their nutrition needs.     

Weight-related attitudes and behaviors of black women

Weight-related attitudes and practices of women who attended health department clinics or who worked for a health and human services agency were assessed by means of an anonymous, self-administered questionnaire. Black women who were 25 to 64 years old and were not pregnant or had not given birth within the past year were included in this analysis (n = 500). The overweight women perceived themselves as being overweight. They were less likely to be satisfied with their weight and more likely to have dieted and to be currently dieting than nonoverweight women. Awareness of obesity-related health risks was high, but the perceived psychosocial consequences of being overweight were somewhat limited. Approximately 40% of moderately and severely overweight women considered their figures to be attractive or very attractive, which indicates a relatively positive body image. The overweight women were less likely to exercise, less likely to skip meals, and more likely to eat between meals than the nonoverweight women. Among the subset who had ever attempted to lose weight (n = 368), the overweight women were significantly more likely to have regained all or more of the weight lost during their most recent attempt. The findings of this exploratory survey suggest that although overweight black women are weight conscious, the absence of strong negative social pressure combined with a relatively positive body image may limit the extent to which weight loss efforts are sustained. Findings about eating and exercise patterns suggest some specific factors that may interfere with the effectiveness of weight control among black women.     

Thyroid radiation absorbed dose from diagnostic procedures in U.S. population

According to a 1981 survey of thyroid imaging methods in the United States, radionuclide thyroid scans and uptake studies increased 250%-300% between 1966 and 1981, while the U.S. population increased only 17%. Collective absorbed dose decreased from 18 X 10(6) rad (18 X 10(4) Gy) in 1966 to 13.9 X 10(6) rad (13.9 X 10(4) Gy) in 1981. The decrease was due to the use of iodine 123 and technetium 99m pertechnetate rather than iodine 131 (I-131 was used for 100% of scans and uptake studies in 1966 and 10% and 54%, respectively, in 1981) and also to fewer free-standing thyroid uptake studies (150,000 in 1966 and 33,000 in 1981). Even with reduced usage, I-131 still accounted for 93% of the collective absorbed dose in 1981. If I-131 were eliminated from diagnostic procedures, the annual absorbed dose would decrease to 1.4 X 10(6) rad (1.4 X 10(4) Gy). The number of radiation-induced cancer cases would also be reduced.
