Knowledge, beliefs, and barriers relevant to colorectal cancer screening in an urban population: a pilot study.

A sample of 115 urban, working-class, predominantly minority men and women was interviewed by telephone to assess knowledge, beliefs, and barriers relevant to colorectal cancer (CRC) and CRC screening. More than half (53.9%) were unable to name a CRC screening test. Misconceptions were common. Dispelling inaccurate beliefs, establishing an individual's preference for fecal occult blood tests or flexible sigmoidoscopy, and helping individuals take a proactive role in the receipt of CRC screening are important goals for health education efforts aimed at increasing rates of CRC screening. Participants' willingness to engage in detailed telephone conversations about CRC and CRC screening was encouraging.

The effect of health education on the rate of ophthalmic examinations among African Americans with diabetes mellitus.

OBJECTIVES: This study evaluated a multicomponent educational intervention to increase ophthalmic examination rates among African Americans with diabetes. METHODS: A randomized trial was conducted with 280 African Americans with diabetes, enrolled from outpatient departments of 5 medical centers in the New York City metropolitan area, who had not had a dilated retinal examination within 14 months of randomization (65.7% female, mean age = 54.7 years [SD = 12.8 years]). RESULTS: After site differences were controlled, the odds ratio for receiving a retinal examination associated with the intervention was 4.3 (95% confidence interval = 2.4, 7.8). The examination rate pooled across sites was 54.7% in the intervention group and 27.3% in the control group. CONCLUSIONS: The intervention was associated with a rate of ophthalmic examination double the rate achieved with routine medical care.

Components of variability in the systolic blood pressures of preschool children.

The term "horse-racing effect" refers to a positive correlation between the slope at which blood pressure increases with age and blood pressure level at a baseline. Previous studies have reported such an effect in adults, while studies in children have found a negative correlation (termed "the Jenss effect"). These studies used analytic methods in which it was assumed that the blood pressure slopes were constant or the blood pressure profiles were linear. In this study, the authors used a components-of-variance approach that did not require this assumption in order to model serial blood pressure measurements made in 216 US preschool children (mean age at first analyzable blood pressure observation, 58.9 months) at 6-13 visits over a 3-year period (1986-1989). Measurements were made using an automated blood pressure monitor. Values from the second and third measures at each visit were averaged to obtain each observation. Data from 2,203 blood pressure observations were available for analysis. For the full group, over the mean period of observation of 21.1 months, the mean rate of increase was 3.45 mmHg/year for systolic blood pressure and 0.06 mmHg/year for diastolic blood pressure. In the authors' model, 33 percent of the total marginal variability in systolic blood pressure was attributed to random error (visit-to-visit variability); average (constant) subject-specific difference from the population slope accounted for 42 percent, and a nonlinear component of variability around the subject-specific average accounted for the remaining 25 percent. All three components were statistically significant. Models which assumed that the slopes were constant did not fit these data, and fitting these models to the data led to an artifactual negative correlation between subject-specific slopes and intercepts. An implication of this is that the concepts of "horse-racing" and "the Jenss phenomenon," which have been operationalized by testing the covariance of the subject-specific slopes and intercepts using models which assume that the blood pressure slopes are constant over time, should not be applied to data that contain this nonlinear component of variance.

Promoting the selection of low-fat milk in elementary school cafeterias in an inner-city Latino community: evaluation of an intervention.

OBJECTIVES: This study examined the effects of a school-based intervention designed to promote the consumption of low-fat white milk at lunchtime in 6 elementary schools in an inner-city, primarily Latino neighborhood. METHODS: A multifaceted intervention based on social marketing techniques was delivered at 3 randomly selected schools. The school was the unit of assignment and analysis; 6902 children were involved in the study. Milk selection and consumption were measured by sampling discarded milk and/or tallying milk carton disappearance at baseline, immediately postintervention, and at 3 to 4 months follow-up. RESULTS: Immediately postintervention, the mean proportion of sampled milk cartons that contained low-fat milk increased in the intervention schools, from 25% to 57%, but remained constant at 28% in the control schools. Differences between intervention and control schools remained significant at 3 to 4 months follow-up. The intervention was not associated with a decrease in overall milk consumption. CONCLUSIONS: A school-based intervention can lead to significant increases in student consumption of low-fat milk.

The telephone as a communication medium for health education.

The telephone is being widely used by the private sector as a communication medium for understanding and influencing consumer behavior. Coinciding with the growth of telephone use in the private sector is the expansion of telephone use in health care to include complex health promotion and disease prevention interventions aimed at initiating and maintaining health-related behavioral changes. While several studies have evaluated the impact of telephone interventions on a wide range of health behaviors, no published reports synthesizing current knowledge about using the telephone as a communication medium for health education were identified. In this article, the authors therefore (1) examine recent applications of telephone use in health education by describing three example interventions, (2) outline key features and alternatives in conceptualizing and designing health education using the telephone, (3) review advantages and disadvantages of using the telephone for health education, and (4) discuss implications for health education practice and research.

The Washington Heights-Inwood Healthy Heart Program: a 6-year report from a disadvantaged urban setting.

OBJECTIVES: This report summarizes 6 years of experience in a large community-based cardiovascular disease prevention program in a predominately minority, urban setting. METHODS: The program seeks to reduce cardiovascular disease risk factors in an area of approximately 240,000 people in New York, NY; this population includes many Latino immigrants of low educational attainment and socioeconomic status. All program materials were in Spanish and English and at a low literacy level. RESULTS: Major elements that achieved high levels of reach and support were a marketing campaign promoting low-fat milk, exercise clubs, and a Spanish-language smoking cessation video. Program elements that did not meet expectations or were abandoned were school-based smoking prevention initiatives, cholesterol screening, and efforts to involve local physicians. At the end of 6 years, the program was transferred to a local community organization. CONCLUSIONS: Conclusions are that it is feasible to implement a complex cardiovascular disease prevention program in a socially disadvantaged urban community; that additional evaluation research is needed; that such programs can be transferred from an academic center to a community organization; and that such programs are unlikely to be sustained effectively without external resources.

The availability of low-fat milk in an inner-city Latino community: implications for nutrition education.

Substitution of low-fat for whole milk is an important strategy for reducing saturated fat consumption, but intake of whole milk remains high among Latinos. To assess whether this is related to the unavailability of low-fat milk, we surveyed 251 grocery stores (bodegas) and 25 supermarkets in a predominantly low-income, urban Latino community. Low-fat milk was available in 73% of bodegas and 96% of supermarkets, but it constituted only 15% of total milk volume in bodegas and 37% of that volume in supermarkets. Since lack of availability was not a major obstacle to increasing low-fat milk consumption, public health nutrition campaigns should focus on increasing consumer demand.

5-A-DAY: dietary behavior and the fruit and vegetable intake of Latino children.

OBJECTIVES: The purpose of the study was to examine children's intake of fruits and vegetables in relation to the recent national "5-A-DAY" campaign. METHODS: Four 24-hour dietary recalls per child collected from 205 mothers of 4- to 5-year-old urban Latino children were used to analyze average 5-A-DAY fruit and vegetable consumption and examine associations between 5-A-DAY consumption, nutrient intakes, and eating patterns. RESULTS: The reported mean servings per day of fruits and vegetables, as defined by 5-A-DAY criteria, were 1.8 and 1.0, respectively, with only 6.8% (n = 14) of the children averaging five or more servings per day. Fruit juice accounted for 36% of 5-A-DAY servings. There were significant linear trends in intake of vitamins A and C, potassium, iron, cholesterol, protein, and fiber across quintiles of 5-A-DAY intake. There were no differences among quintiles in intake of saturated or total fat or in servings from most non-5-A-DAY food groups. CONCLUSIONS: Latino children's intake of fruits and vegetables falls far short of current recommendations. Fruit juice accounted for a disproportionate amount of 5-A-DAY intake in this population. Sensible 5-A-DAY interventions should take into consideration the existing eating patterns of the target population.

The reproducibility of data from a Food Frequency Questionnaire among low-income Latina mothers and their children.

We examined the 3-month and 1-year reproducibility of mothers' and children's dietary intakes of calories and 11 nutrients derived from oral administrations of a food frequency questionnaire to 166 Latina women. One-year correlations generally ranged from 0.40 to 0.55 for both mothers and children. For most nutrients, roughly half the children in the highest (lowest) quartile of intake at baseline were also in the highest (lowest) quartile 1 year later. The food frequency questionnaire has great potential for measuring typical nutrient intakes in these populations.

The rate of increase in blood pressure in children 5 years of age is related to changes in aerobic fitness and body mass index.

OBJECTIVE: To determine whether changes in aerobic fitness and body mass index are related to the age-related rise in blood pressure in healthy preschool children. STUDY DESIGN: Longitudinal analyses of 196 free-living children aged 5 years at baseline who were followed over a mean of 19.7 months. Aerobic fitness was assessed using a treadmill. All measures were obtained on multiple occasions at scheduled visits as part of a longitudinal cohort study. SETTING: An inner-city medical center. OUTCOME MEASURES: Blood pressure was measured using an automated Dinamap device. RESULTS: Mean systolic blood pressure was 95.3 mmHg (SD 8.38) at baseline and increased by 4.46 mmHg per year. Mean diastolic blood pressure was 53.9 mmHg (SD 5.81) at baseline and did not change significantly. Children in the highest quintile of increase in fitness had a significantly smaller increase in systolic blood pressure compared to children in the lowest quintile (2.92 vs 5.10 mmHg/year; P = .03). Children in the lowest quintile of increase in body mass index did not differ significantly in rate of increase in systolic blood pressure compared to children in the highest quintile (3.92 vs 4.96 mmHg/year). In a multiple regression model including baseline systolic blood pressure, fitness, height, body mass index, and other covariates, greater increase in fitness (P = .03) and lesser increase in body mass index (P < .01) were associated with lower rates of increase in systolic blood pressure. In a similar multivariate analysis, an increase in fitness was also associated with a lower rate of increase in diastolic blood pressure (P = .02). CONCLUSION: Young children who increase their aerobic fitness or decrease their body mass index reduce the rate of the age-related increase in blood pressure. These observations may have implications for development of interventions directed at the primary prevention of hypertension.

Assessing changes in nutrient intakes of preschool children: comparison of 24-hour dietary recall and food frequency methods.

Methods for assessing change in the habitual diet of children are essential for diet intervention studies as well as clinical management. Food frequency questionnaires are a potential alternative to recall and record methods, which require multiple days of data collection for stable individual estimates of habitual intake. Over 3 years, we studied 173 children (93% Hispanic; baseline age 44-60 months) in New York City. We obtained dietary data by interviewing the child's mother. We calculated intakes of nine nutrients, expressed as nutrient densities, as the mean of two administrations of the Willett food frequency questionnaire and the mean of three administrations of the 24-hour dietary recall in years 1 and 3. The two methods consistently estimated the direction of change in mean nutrient density of total and polyunsaturated fat, cholesterol, carbohydrate, and potassium. Changes in nutrient density assessed by the two methods correlated poorly (r < or = 0.15) for all nine nutrients. Cross-classification analysis also showed no relation between change assessed by recall and food frequency methods. Lack of between-person variability could not explain the low correlations, as individual changes in nutrient density were large.

Age, sex, educational attainment, and race/ethnicity in relation to consumption of specific foods contributing to the atherogenic potential of diet.

BACKGROUND: We examined which specific foods contributed to the atherogenic potential of diet in population segments defined by age, sex, educational attainment, and race/ethnicity. Data from the 1989 New York State Healthy Heart Program baseline survey were analyzed. METHODS: This telephone survey was conducted in eight communities (total population approximately 1.24 million people) in New York State. Response rate was 65.5% (N = 4,179); 3,606 subjects ages 20 to 64 years who reported their level of educational attainment with self-described ethnicity of white (N = 1,935), black (N = 1,035), or Hispanic (N = 636) were retained in the analysis. Diet was assessed using a 17-item food frequency questionnaire which focused on commonly eaten food high in saturated fat and cholesterol. Connor's cholesterol/saturated-fat index was used as a scale of the atherogenic potential of the diet. RESULTS: Eggs, whole milk, cheese, beef, and butter/margarine were the foods contributing most to the cholesterol/saturated-fat index score in all age-, sex-, and race/ethnicity-specific population segments examined, together contributing a total of 52 to 72% of the cholesterol/saturated-fat index score as measured by the 17-item diet questionnaire. CONCLUSIONS: The implication for public health campaigns directed at reducing the atherogenic potential of diet atherogenicity and for primary care practitioners seeking to influence the diet of patients with high blood cholesterol is that substitutions of less atherogenic food choices for these five foods would appear to be appropriate for most adults.

Is there a relationship between dietary fat and stature or growth in children three to five years of age?

STUDY OBJECTIVE: To determine whether a moderately reduced fat diet affects the stature or growth of healthy preschool children. DESIGN: Cohort study with mean of 25 months of follow-up. SETTING: Primary care pediatrics practice at a large urban medical center. SUBJECTS: A predominantly Hispanic group of 215 children aged 3 to 4 years at baseline. MEASUREMENTS AND MAIN RESULTS: The children's diet was assessed using four 24-hour recalls and three Willett semiquantitative food-frequency questionnaires administered to the children's mothers over a 1-year baseline period. Stature was defined in terms of height, weight, and body mass index at baseline. Growth was defined in terms of change during follow-up in height, weight, and body mass index. Total fat provided a mean of 27.1% of caloric intake in the lowest quintile of intake compared with 38.4% in the highest quintile. There were no differences in stature or growth across quintiles of children defined by consumption of total fat, saturated fat, or cholesterol. These findings were consistent across the two methods of diet assessment. Children who consumed a smaller percentage of total calories from fat consumed significantly less total calories, saturated fat, cholesterol, calcium, and phosphorus, as well as more carbohydrates, iron, thiamine, niacin, vitamin A, and vitamin C. CONCLUSIONS: These data support the safety of a moderately reduced fat diet in healthy preschool children. Maintenance of calcium and phosphorus intake should be part of any program of dietary fat reduction. Substitution of low-fat milk for whole milk, rather than elimination of whole milk, is one such strategy.

Blood pressure reactivity does not correlate with baseline blood pressure or blood pressure change over time in preschool children.

Few studies have examined the relation of blood pressure reactivity to subsequent change in blood pressure of preschool children. The authors investigated relations between measurement-induced reactivity, exercise reactivity, and change in blood pressure over 16 months among 140 preschool children (46-67 months of age at baseline, 50.7% female, 92.9% Hispanic). Within-session measurement-induced reactivity was defined as the change in blood pressure between the first and the mean of the fourth and fifth readings obtained at each of 11 sessions. Between-session measurement-induced reactivity was defined as the change between mean blood pressure at session 1 and the mean of sessions 2 and 3. Both indices of measurement reactivity displayed poor reproducibility. Exercise reactivity was measured using a treadmill on two occasions and was moderately reproducible. There was no association between measurement and exercise reactivity. The change in systolic blood pressure over time was not associated with any measure of reactivity. The mean diastolic blood pressure did not change over the study period. Neither blood pressure reactivity to measurement nor blood pressure reactivity to exercise appeared to be a useful predictor of change in blood pressure in preschool children during a 16-month period.

Consistency of the Willett semiquantitative food frequency questionnaire and 24-hour dietary recalls in estimating nutrient intakes of preschool children.

A study was performed to determine the utility of the Willett semiquantitative food frequency questionnaire for assessing the habitual diets of preschool children. Children (n = 224) were recruited mainly through a New York City hospital-based pediatric practice during 1986-1987. The children's ages at baseline were 44-60 months; 50% were male, and 91% were Hispanic. Over a 12-month period, the Willett food frequency questionnaire was administered twice to each child's parent, and a 24-hour dietary recall was conducted four times. For energy and eight nutrients, group mean intakes derived from food frequency questionnaires were 1.4-1.9 times higher than those from 24-hour recalls. Group mean estimates of nutrient density of total and saturated fat, potassium, and calcium did not differ between the two methods. Correlations between methods for crude nutrient intakes (unadjusted for energy consumption) ranged from 0.16 (polyunsaturated fat in boys) to 0.60 (potassium in girls). Correlations generally decreased when intakes were adjusted for energy consumption. Adjustment for energy intake and residual intraindividual variability yielded correlations of 0.48 for total calories, 0.35 for total fat, and 0.37 for saturated fat. For intake of energy and nine nutrients, of those children classified into the highest quintile by dietary recall, 28.9-40.9% were so classified by the Willett questionnaire, and 48.9-68.9% were classified into the highest two quintiles. When data were expressed as nutrient densities, agreement was high for potassium and calcium and fair for saturated fat, cholesterol, and protein. The moderately low consistency of nutrient intake estimates across dietary assessment methods in this study may be due, in large part, to residual intraindividual variability in both the recall data and the food frequency data.

The Washington Heights-Inwood Healthy Heart Program: a third generation community-based cardiovascular disease prevention program in a disadvantaged urban setting.

The Washington Heights-Inwood Healthy Heart Program (WHIHHP) is part of the New York State Healthy Heart Program, which comprises eight community-based programs in different areas of the state. WHIHHP is directed at a population of approximately 200,000 people, predominantly Hispanic and of low socioeconomic status, living in northern Manhattan in New York City. The initial 3 years of experience are presented. Six potential barriers to diffusion of the community-based disease prevention model in disadvantaged inner city communities are discussed: (a) issues of scale and complexity; (b) adaptation of this model to a "community" without geopolitical boundaries or infrastructure; (c) linguistic and cultural diversity; (d) competing problems; (e) the role of evaluation; and (f) sustainability of the program in a poor community. Strategies for addressing obstacles to model adoption are also described, including program legitimization, building program infrastructure, setting realistic expectations, focusing on one risk factor at a time, defining target population segments, and emphasizing a small number of communication channels. Finally, research issues related to the diffusion of the community-based model are discussed, specifically: (a) Does the model work in disadvantaged urban settings? (b) What are the program effects on social class gradients for risk factors? (c) What are the barriers to program adoption in such settings? (d) What changes in the model will facilitate adoption in such settings? (e) What are the best methods for conducting formative evaluation in such programs? (f) What is the best way to select communities that may be ready to adopt the model? Our initial experience implementing this model in a disadvantaged urban setting supports the feasibility of model adoption. Unanswered questions about efficacy in such settings and regarding research issues related to model diffusion will require additional research investment.
