A brief dietary assessment to guide cholesterol reduction in low-income individuals: design and validation.
Low-income Americans are at greatest risk for coronary heart disease. Dietary assessment methods are needed that can efficiently and effectively guide diet counseling to reduce serum cholesterol in this population. The Dietary Risk Assessment is a brief food frequency questionnaire designed to guide an intervention program for cholesterol reduction. It can easily be administered and scored in 10 to 15 minutes by persons who are not trained in nutrition. The assessment is culturally specific for a low-income southern population, identifies positive as well as problematic dietary behaviors, is easily interpreted, and measures potential barriers to dietary change. The assessment was validated against 3 days of dietary recall data in a sample of 42 low-income individuals recruited from the waiting room of an ambulatory care clinic. A Keys score, which measures the serum-cholesterol-raising potential of the diet, was calculated for each patient from their recall data. The Keys and Dietary Risk Assessment scores were significantly correlated (r = .60, P less than .001). We conclude that the Dietary Risk Assessment can rank individuals by level of dietary atherogenic risk adequately to guide a dietary treatment program for low-income patients, an underserved population with a high prevalence of diet-induced elevations in serum cholesterol.

[Hypertension from the perspective of a low-income population: an exploratory study of knowledge, attitudes, and practices].
Knowledge, attitudes, and behaviors related to high blood pressure among adults in a low-income community in Caucaia, Ceará, Brazil, as well as factors influencing their attitudes toward behavioral risk factors (smoking, alcohol consumption, salt and fat consumption, and lack of physical exercise) were studied. A total of 228 individuals were interviewed using a structured interview protocol. Thirteen focus groups provided a more in-depth analysis of attitudes. According to the findings, the reasons behind behaviors and attitudes are linked to emotions and socioeconomic issues. Behavioral changes involve giving up certain pleasures, for people who are struggling to survive in living conditions imposed by poverty. Living in poverty interferes with the possibility of behavioral change.

Use of complementary/alternative medicine by men diagnosed with prostate cancer: prevalence and characteristics.
OBJECTIVES: To ascertain the prevalence of the use of complementary/alternative medicine (CAM) among a random sample of Ontario (Canadian) men diagnosed with prostate cancer and to explore in what way users of CAM differ from nonusers. METHODS: A questionnaire was mailed to a random sample of 696 men diagnosed with prostate cancer. RESULTS: The final response rate was 78.8%. Almost one third (29.8%) reported using CAM for their prostate cancer care. Natural health products (most commonly vitamin E, saw palmetto, and selenium) were used by 26.5% of the respondents. CAM therapies were used by 17.0% of the men (most commonly dietary changes), and only 9.1% visited CAM practitioners. Three characteristics appear to differentiate CAM users from nonusers. Men who had attended support groups were much more likely to use CAM. Men who had more advanced disease, and those who believed in the efficacy of CAM, but were not concerned about potential adverse effects of CAM, were also more likely to use CAM. CAM use was not related to education, income, or geographic location. CONCLUSIONS: The data suggest that CAM use is no longer a phenomenon restricted to a unique segment of the population that is highly educated and enjoys a high family income. CAM use appears to be more related to other factors such as support group attendance, disease characteristics, and beliefs about CAM. Our findings highlight the need for urologists to ask all their patients about their use of CAM.

"I don't know when it might pop up": understanding repeat HIV testing and perceptions of HIV among drug users.
PURPOSE: The study sought to understand the HIV testing patterns of low-income drug users. METHODS: Sixty-seven low-income drug users were recruited from street outreach venues in three San Francisco Bay Area counties. Participants were interviewed using an open-ended questionnaire eliciting information on HIV testing histories, sexual behavior, and drug use. Transcripts from interviews were coded and analyzed using methods consistent with the grounded theory approach of qualitative research. RESULTS: Participants identified four themes related to HIV testing: (1) anticipating positive results, (2) belief in a 10-year window period during which the virus is undetectable, (3) regular HIV testing as part of self-care, and (4) the HIV test as a means of control. These themes did not relate to personal risk behavior but rather to the community experience of HIV in small, dense populations of low-income drug users with high rates of HIV infection. IMPLICATIONS: Participants used HIV testing like regular mammograms or blood pressure checks, as if it were a screening procedure for a chronic illness. This is a reasonable response given the context of HIV within their communities. HIV testing in this population should not be limited.

Factors associated with unconstrained growth among affluent Ghanaian children.
AIM: To identify socio-economic factors associated with unconstrained growth among children living in well-off neighbourhoods of Accra, Ghana. METHODS: A cross-sectional study involving the assessment of the anthropometric status of preschool children. Children (n = 309) between the ages of 12 and 23 mo who live in affluent communities in Accra, Ghana were recruited for the study. Weight, length and mid-upper arm circumference were taken. Information was collected on household demographics and socio-economic status, including parental education and household income. Associations between these variables and attained growth were analysed to establish cut-offs for screening children with unconstrained growth. RESULTS: The mean weight-for-age (WA), length-for-age (LA) and weight-for-length (WL) Z-scores of the sub-sample selected on the basis of high socio-economic criteria were -0.18, -0.40 and 0.16, respectively. Among these well-off children, 0% were underweight, 3.0% were stunted and 0% were wasted (Z-scores <-2). Factors associated with better anthropometric status were paternal education and household income. Two screening criteria combining the two variables were selected: polytechnic education and income > 1,000,000 cedis (435 US dollars) or university education and income > 200,000 cedis. CONCLUSIONS: The children experiencing unconstrained growth belonged to a sub-population of affluent households characterized by high paternal education and household income. This subpopulation was targeted for screening for the WHO Multicentre Growth Reference Study in Ghana.

The appearance of discretionary income: influence on the prevalence of under- and over-nutrition.
Undernutrition--protein energy malnutrition or specific nutrient deficiencies--has been an inherent characteristic of impoverished populations throughout the world. Over-nutrition, obesity and nutrition imbalance is a current concern among those with rising though still insufficient incomes. We review data to suggest that the prevalence of these forms of malnutrition in populations is highly influenced by the rate of appearance of discretionary income. In developed countries, discretionary (alternatively "disposable") income refers to funds available after obligate payments (rent, heat, and the cost of getting to work) and payment for necessities (food and clothing). For families living at or below poverty, the last dollar earned is spent on these obligations. Undernutrition is common. By contrast, likelihood for obesity or imbalance increases with rising income when that last dollar is earned without certainty that it is available for discretionary spending. In the United States, neither under- nor over-nutrition is likely when new income is free and clear of debt or obligation. This occurs at approximately three times the poverty level. While income poverty and food insecurity affect risk for malnutrition rather than outcome, nutrition education programs that address issues of income and food support increase likelihood for adherence to recommendations.

Prevention of early childhood caries.
This paper reviews the methods used for the prevention of early childhood caries (ECC). The education of mothers or caregivers to promote healthy dietary habits in infants has been the main strategy used for the prevention of ECC. This review found that education has a modest impact on the development of ECC. While education should be promoted especially in high risk communities and population groups (low-income families and native populations), it should not be the only preventive strategy of ECC. Early screening for signs of caries development, starting from the first year of life, could identify infants and toddlers who are at risk of developing ECC and assist in providing information to parents about how to promote oral health and prevent the development of tooth decay. High risk children include those with early signs of ECC, poor oral hygiene, limited exposure to fluorides, and frequent exposure to sugary snacks and drinks. These children should be targeted with a professional preventive program that includes fluoride varnish application, fluoridated dentifrices, fluoride supplements, sealants, diet counseling, and chlorhexidine. Prevention of ECC also requires addressing the social and economic factors that face many families where ECC is endemic.

Who is caring for the underserved? A comparison of primary care physicians and nonphysician clinicians in California and Washington.
PURPOSE: Little is known about whether different types of physician and nonphysician primary care clinicians vary in their propensity to care for underserved populations. The objective of this study was to compare the geographic distribution and patient populations of physician and nonphysician primary care clinicians. METHODS: This study was a cross-sectional analysis of 1998 administrative and survey data on primary care clinicians (family physicians, general internists, general pediatricians, nurse practitioners, physician assistants, and certified nurse-midwives) in California and Washington. For geographic analysis, main outcome measures were practice in a rural area, a vulnerable population area (communities with high proportions of minorities or low-income residents), or a health professions shortage area (HPSA). For patient population analysis, outcomes were the proportions of Medicaid, uninsured, and minority patients in the practice. RESULTS: Physician assistants ranked first or second in each state in the proportion of their members practicing in rural areas and HPSAs, and in California physician assistants also had the greatest proportion of their members working in vulnerable populations areas (P < .001). Compared with primary care physicians overall, nurse practitioners and certified nurse-midwives also tended to have a greater proportion of their members in rural areas and HPSAs (P < .001). Family physicians were much more likely than other primary care physicians to work in rural areas and HPSAs (P < .001). Compared with physicians, nonphysician clinicians in California had a substantially greater proportion of Medicaid, uninsured, and minority patients (P < .001). CONCLUSIONS: Nonphysician primary care clinicians and family physicians have a greater propensity to care for underserved populations than do primary care physicians in other specialties. Achieving a more equitable pattern of service to needy populations will require ongoing, active commitment by policy makers, educational institutions, and the professions to a mission of public service and to incentives that support and promote care to the underserved.

Acceptability of computer assessments among ethnically diverse, low-income smokers.
PURPOSE: To examine the acceptability of computer-based assessments among an ethnically diverse, low-income population of primary care patients. Although computers have been used to provide assessments and interventions in health care settings, members of ethnic minority and low-income households have less access to computers than other groups, and therefore the acceptability of computers as a health care assessment and delivery tool needs to be examined. DESIGN: We examined the acceptability of computers for providing assessments of smoking history, nicotine dependence, and other related variables among an ethnically diverse, low-income primary care population. No intervention was used in this study. SETTING: Three inner-city primary care clinics located in hospitals were used as sites for this study. These hospitals were located in areas of the city where low-income and ethnic minority households are overrepresented relative to the total population. SUBJECTS: Adult male and female smokers (n = 522) were recruited while awaiting appointments in each primary care clinic. MEASURES: A questionnaire assessing smoking rate, patterns, history, motivation to quit smoking, and other smoking-related variables was administered using either a paper-and-pencil format or a laptop computer. RESULTS: Frequency counts, analysis of variance, and chi 2 tests were used where appropriate. Most subjects (78.5%) used the computer to complete the baseline survey. Almost all subjects (92%) rated the computer "very easy" or "easy" to use. Subjects who were Spanish-speaking, were born outside the United States, or were Hispanic tended to rate the program as slightly less easy to use than other subjects. CONCLUSIONS: Computer-based assessments appear highly acceptable to individuals in low-income populations.

The growth pattern of Saudi Arabian pre-school children in Riyadh compared to NCHS/CDC reference population.
This study compares the growth patterns of Saudi Arabian pre-school children aged 0-5 years to a reference population of American children documented by the National Center for Health Statistics/Centers for Disease Control (NCHS/CDC). The anthropometric data of weight, height and age were collected in a cross-sectional study of Saudi Arabian children in Riyadh, the capital of Saudi Arabia. The sample selection was accomplished by a 3-stage stratified random procedure, basing the stratification on location and a socio-economic index. A total of 3,795 children comprising 55.2% males and 44.8% females had complete basic anthropometric measurements among other variables. Analyses were effected by using the WorHealth Organization/Centers for Disease Control (WHO/CDC) standard software programme for calculating nutritional indicators. A combination of height for age (as an indicator of stunting) and weight for height (as an indicator of wasting) showed that a sizeable proportion (78.1%) have normal or slightly above normal nutritional status. A small proportion of the children (1.4%) were below -2.0 SD scores of the reference population for weight for height and for age. Overall, Saudi Arabian children are slightly shorter and thinner than their American counterparts. An important finding in weight for height was that nearly 20% of the children were below -2 SD scores of the reference population median. However, due to the very high per capita income, and the fact that food and other essential items are subsidised by the government, the deficits from this reference population may be attributed to inadequate health education nutrition programmes, genetic and other social factors including reproductive behaviour, rather than malnutrition.

High prevalence of food insecurity and hunger in households in the rural Lower Mississippi Delta.
CONTEXT: Residents of the Lower Mississippi Delta of Arkansas, Louisiana, and Mississippi are at risk for food insecurity since a high proportion of the population live in households with incomes below the poverty level and have reduced access to food and decreased availability of a variety of foods. However, the magnitude of the problem is unknown because presently only nationwide and state estimates of food insecurity are available. PURPOSE: This study was conducted by the Lower-Mississippi Delta Nutrition Intervention Research Consortium to determine the prevalence of household food insecurity, identify high-risk subgroups in the Lower Delta, and compare to national data. METHODS: A 2-stage stratified cluster sample representative of the population in 36 counties in the Lower Delta was selected using list-assisted random digit dialing telephone methodology. A cross-sectional telephone survey of 1662 households was conducted in 18 of the 36 counties using the US Food Security Survey Module. FINDINGS: Twenty-one percent of Lower Delta households were food insecure, double the 2000 nationwide rate of 10.5%. Within the Lower Delta, groups with the highest rates of food insecurity were households with income below $15,000, black households, and households with children. The prevalence of hunger in Delta households with white children was 3.2% and in households with black children was 11.0%, compared to nationwide estimates of 0.3% and 1.6%. CONCLUSIONS: The Lower Mississippi Delta is characterized by a high prevalence of food insecurity and hunger. Future efforts to identify the household and community determinants of food insecurity to reduce its high prevalence are indicated.

Dust mite, cockroach, cat, and dog allergen concentrations in homes of asthmatic children in the northeastern United States: impact of socioeconomic factors and population density.
Home exposures to aeroallergens are an important environmental factor in allergic sensitization and in the development and exacerbation of asthma. We assessed variations in home concentrations of dust mite, cockroach, cat, and dog allergens in dust collected in the main living areas of asthmatics' homes by family income, mother's education, dwelling type, population density, household population density, and ethnicity in Connecticut and south-central Massachusetts. Dust samples were collected at the time of home interview in 999 homes as part of an ongoing longitudinal birth cohort study of 1,002 infants and their asthmatic siblings. The analysis employed lower and upper cut points for group 1 dust mite (> or = 2.0 microg/g and > or = 10 microg/g), cockroach (> or = 1.0 U/g and > or = 4.0 U/g), cat (> or = 1.0 microg/g and > or = 8.0 ug/g), and dog (> or = 2.0 microg/g and > or = 10.0 microg/g) allergens. Subject residences were geocoded to assess population density from the U.S. Census, and multiple logistic regression was used to control for confounding. The portion of homes at the lower cut point for dust mite, cockroach, cat, and dog allergens were 46.9%, 24.9%, 42.2%, and 35.6%, respectively; the upper cut point for each of the allergens was reached in 22.4%, 13.4%, 21.0%, and 22.9% of the homes, respectively. In all, 86.0% of the homes had at least one allergen at the lower cut point, and 58.0% had at least one allergen at the upper cut point. Forty-nine percent of the homes had two or more allergens at the lower cut point, and 19.7% had two or more allergens at the upper cut point. Higher education of the mother, higher household income, living in a single-family home in a less densely populated area with fewer people per room, and being a white household were associated with elevated dust mite, cat, and dog allergens and low cockroach allergen. In contrast, low income, living in a multifamily home in a high population density area with a higher occupancy rate per room, and being a Hispanic or black household were associated with elevated cockroach allergens and low concentrations of dust mite, cat, and dog allergens. Although the presence of an individual allergen is more likely associated with one or more socioeconomic or ethnic factors, most homes typically have multiple allergen burdens in excess of concentrations thought to be associated with sensitization and exacerbation of asthma. Mite and cockroach allergens have distinct and opposite associations with socioeconomic factors and population density.

Neighborhood composition and incidence of cancer among Hispanics in the United States.
BACKGROUND: Hispanics in the United States have a 33% lower age-adjusted incidence of cancer and a 38% lower cancer mortality rate compared with non-Hispanic whites. This may be secondary to health behaviors that vary with residential and economic assimilation. The authors investigated whether cancer incidence among Hispanics increased with residential and economic assimilation into mainstream culture. METHODS: Data from the Surveillance, Epidemiology, and End Results program (SEER) and the U.S. Census Bureau were used to compare cancer incidence rates and rate ratios as a function of percentage of Hispanics and income of Hispanics in a census tract. Type of cancer was identified with a site recode variable in the SEER data set. Cases with in situ prostate and cervical carcinoma were excluded. Hispanic ethnicity in SEER was identified by medical record review and Hispanic surname lists. The study also used income of Hispanics living in the census tract, age at diagnosis, and stratification by gender. RESULTS: The incidence of breast, colorectal, and lung carcinoma among Hispanics increased as the percentage of Hispanics in the census tract decreased and as tract Hispanic income increased. For example, there was a 39% reduction in breast carcinoma and a 38% reduction in male colorectal carcinoma when the Hispanic population in high-density Hispanic neighborhoods in the lowest income quartile was contrasted to Hispanics living in tracts with the lowest total percentage of Hispanics in the highest income quartile. CONCLUSIONS: The lower cancer rates among Hispanics relative to non-Hispanic whites in the United States may dissipate as Hispanics become more assimilated into the mainstream society.

Biodemographic and sociocultural factors in two generations of families from six Polish rural and urban populations.
There were investigated 6967 families from 6 rural regions, under industrialization, and industrialized urban regions. In the grandparents generation there were taken into account 10 traits (an education level, a mating radius, and a stature) and in parents generation 17 traits (the mentioned-above ones and a number of family members, a flat size, incomes, an employees No., a life mode, smoking etc. Numerical characteristics of traits have been calculated jointly and separately in six populations, matrices of correlation have been constructed and moreover factorial analysis have been carried out, as a result of which 8 rotated factors have been obtained. The highest cultural mobility (increase in the level of education) from generation to generation occurs in the population of textile industry town Lódź. The highest improvement of biological status, the increase in mating radius and high incomes are characteristic for this regions, too. On the other side are villages with low culture mobility (not large increase in education level), slight improvement of biological status, almost no migrations, overcrowded flats and low income per family member. The relations between pairs of traits appear to vary largely in several populations. Generally is a high correlation between the education level of the same family members in both generations. The has been stated negative correlation between grandfather stature both of the mother and the father lines, with occurring of positive assortative mating in the couples of two generations. In both investigated generations there is the positive assortative mating, but the negative correlation in the stature between grandfathers of the mother and the father lines. The grandparents education level is correlated with their and their offsprings stature. The duration of holidays is one of the best (closely correlated with others) indicators of life mode, and partially of a given family living conditions, too. 8 hidden factors have been separated: a consciousness, mode of life, a number of family members, a genetic factor (stature), migrations, living conditions, incomes. This 8 factors have different ranks (evaluated as a position in sequence expressing in % the share in being explained variance) in six investigated rural and urban populations, explaining together 54-55% of the total variance of analyzed family traits. The consciousness occurs generally as a first factor. As far, as the mode of life is concerned, the rank of its factor is less in villages than in towns, and reciprocally the ranks of such factors as a number of family members, migrations and living conditions, are greater in villages than in towns.

Dental caries and periodontal disease among Mexican-American children from five southwestern states, 1982-1983.
Analysis of Southwestern HHANES data showed that the prevalence of dental caries among Mexican-American children is similar to that of children of the same age examined during the NIDR survey (1979-1980), despite a lower level of restorative treatment. Approximately 50% of Mexican-American children 17 years of age, however, had five or more teeth that were either decayed or filled. Occlusal surfaces of molars were the most susceptible teeth to decay; few anterior teeth were affected. This distribution of dental caries strongly supports the use of fissure sealants on molar teeth. Children from low-income families had two times more decayed teeth than children from high-income families. Mild gingivitis and poor oral hygiene were more prevalent in the Mexican-American children than in the child population for the region examined during NHANES I in 1971-1974. Children from high-income families had better periodontal health than those from low-income families.
