Colorectal cancer screening: recommendations and guideline adherence by physicians from digestive endoscopy centers in the Lazio region, Italy.

INTRODUCTION: Endoscopy plays a key role in colorectal cancer screening; at the beginning of a mass screening campaign, it is important for public health officials to assess physicians' attitudes and adherence to guidelines regarding colorectal cancer screening. METHODS: In April 2004, a questionnaire was sent to all 80 digestive endoscopy centers in the Lazio region, identified by the annual census of the Italian Society of Digestive Endoscopy. The results were compared to those from a similar survey of general practitioners (GPs). RESULTS: Seventy-one centers (89%) returned the questionnaire. Only 3% of physicians said they did not recommend any colorectal cancer screening test. Colonoscopy was perceived as the most effective screening test and was the most recommended (80%). Fecal occult blood test was recommended by 61% of physicians and flexosigmoidoscopy by 11%. Endoscopy centers' physicians recommend screening more than GPs (96.9% vs. 78.3%), while they have a similar level of over-recommending (50.8% vs. 47.2%). Almost 95% of endoscopy physicians properly recommended colonoscopy after positive FOBT. CONCLUSIONS: Neither physicians at endoscopy centers nor GPs tend to follow screening guidelines. Screening programmes should not rely on a single medical specialist, but on interdisciplinary management of the disease to strengthen adherence to existing guidelines.

Parental occupational exposure to magnetic fields and childhood cancer (Sweden).

OBJECTIVES: To test the hypothesis that parental occupational exposure to magnetic fields before conception and during pregnancy increases the risk of cancer in the offspring. METHODS: The study is designed as a cohort study based on a population of 235,635 children born shortly after two different censuses in Sweden. The children were followed from birth to 14 years and cases of cancer were identified in the Swedish cancer registry. The parents' occupational titles in the censuses were linked to a job-exposure matrix with information about magnetic field levels in different occupations. The cancer incidence among the exposed was compared to that among the unexposed using Cox proportional hazards modeling. RESULTS: There was no association between childhood cancer and maternal occupational magnetic field exposure. Paternal exposure was associated with an increased risk of childhood leukemia, with a relative risk of 2.0 (95% CI 1.1-3.5) for exposures > or = 0.30 microT. A decreased risk was found for brain tumors (RR = 0.5; 95% CI 0.3-1.0). CONCLUSIONS: The results do not support previous findings of an increased risk of childhood brain tumors associated with paternal occupational exposure to magnetic fields. The finding for childhood leukemia has to be interpreted with caution.

Inequalities in availability of National Health Service general dental practitioners in England and Wales.

AIM: To model the inequalities in availability of National Health Service general dental practitioners in England and Wales in relation to key socio-demographic factors. METHODS: Current estimates of the numbers of NHS general dental practitioners for each health authority were related to data from the 1991 census using Poisson regression models, and generalised estimating equations to allow for correlation between results for neighbouring health authorities. RESULTS: An 'average' health authority, without a dental school, would be expected to have 2,138 residents for every NHS dentist. Controlling for relevant factors, health authorities with higher proportions of the following are associated with lower (better) population to dentist ratios by the amounts shown: each 1% higher female population (-11.8%; 95%CI -19.1%, -3.9% P = 0.004); each 1% greater South Asian population (-1.4%; 95%CI -2.1%, -0.7% P <0.001). A health authority with a dental school is associated with a more favourable ratio compared with one without such a facility (-9.2%; 95%CI -16.2%, -1.6% P = 0.019). Each additional 1% of the following are associated with a worse ratio by the amounts shown: children aged 0 to 14 years old (+5.2%; 95% CI +2.4%, +8.1% P < 0.001); adults aged over 65 years old (+2.8%, 95%CI +1.0%, +4.7% P =0.002); households without a car (+0.8%; 95%CI 0.0%, +1.6% P =0.042). CONCLUSIONS: Ensuring access to dental care may be a more complex issue than simply providing adequate numbers of dentists at a national level. Any manpower planning exercise should additionally consider local factors that may act as incentives or disincentives to those professionals who provide care.

Between harm and dangers. Oral snuff use, cigarette smoking and problem behaviours in a survey of Swedish male adolescents.

BACKGROUND: The prevalence of smokeless tobacco use (moist snuff) in Sweden is among the highest world-wide, and snuff is gaining popularity as a less harmful alternative to cigarettes. METHODS: Patterns of current tobacco use and indicators of behavioural problems were analysed in a sample of 6287 boys participating in a census survey among 9th graders in Stockholm County, Sweden. RESULTS: Among participants reporting current use of oral snuff (OS) the majority (71%) also smoked cigarettes. The prevalence of daily smoking was significantly higher in this group than among exclusive smokers. Conditionally on smoking behaviour, the likelihood of being a current user of OS was several times higher among boys who had ever been drunk (adjusted odds ratio = 9.64, 95% confidence interval: 7.32-12.94) or experimented with illicit drugs (adjusted odds ratio = 2.39, 95% confidence interval: 1.99-2.87), compared with those who did not. OS use was also significantly associated to other problem behaviours such as drinking and driving, unsafe sex, and school truancy. The same pattern of associations was present when the analyses were restricted to tobacco users. CONCLUSIONS: Smokeless tobacco use in adolescence does not substitute cigarette smoking and can be an indicator of a drug- and risk-seeking lifestyle. The availability of smokeless tobacco might thus increase the potential for nicotine addiction in some vulnerable subgroups of young males.

Monitoring socioeconomic inequalities in sexually transmitted infections, tuberculosis, and violence: geocoding and choice of area-based socioeconomic measures--the public health disparities geocoding project (US).

OBJECTIVES: To determine which area-based socioeconomic measures, at which level of geography, are suitable for monitoring socioeconomic inequalities in sexually transmitted infections (STIs), tuberculosis (TB), and violence in the United States. METHODS: Cross-sectional analysis of public health surveillance data, geocoded and linked to area-based socioeconomic measures generated from 1990 census tract, block group, and ZIP Code data. We included all incident cases among residents of either Massachusetts (MA; 1990 population = 6016425) or Rhode Island (RI; 1990 population = 1003464) for: STIs (MA: 1994-1998, n = 26535 chlamydia, 7464 gonorrhea, 2619 syphilis; RI: 1994-1996, n = 4473 chlamydia, 1256 gonorrhea, 305 syphilis); TB (MA: 1993-1998, n = 1793; RI: 1985-1994, n = 576), and non-fatal weapons related injuries (MA: 1995-1997, n = 6628). RESULTS: Analyses indicated that: (a). block group and tract socioeconomic measures performed similarly within and across both states, with results more variable for the ZIP Code level measures; (b). measures of economic deprivation consistently detected the steepest socioeconomic gradients, considered across all outcomes (incidence rate ratios on the order of 10 or higher for syphilis, gonorrhea, and non-fatal intentional weapons-related injuries, and 7 or higher for chlamydia and TB); and (c). results were similar for categories generated by quintiles and by a priori categorical cut-points. CONCLUSIONS: Supplementing U.S. public health surveillance systems with census tract or block group area-based socioeconomic measures of economic deprivation could greatly enhance monitoring and analysis of social inequalities in health in the United States.

Psoriasis in Swedish conscripts: time trend and association with T-helper 2-mediated disorders.

BACKGROUND: According to the T-helper (Th)1/Th2 paradigm, it has been argued that Th1-dominated diseases such as psoriasis and Th2-dominated diseases such as asthma and hay fever should be mutually exclusive, as the immune regulatory cells, Th1 and Th2, cross-regulate each other. An increase in asthma and hay fever has occurred in Sweden over the past four to five decades, but the time trend for psoriasis is not clear. OBJECTIVES: To assess the prevalence of psoriasis in young Swedish men over a period of three decades and the association between psoriasis and allergic disorders. METHODS: Register study based on data from the Swedish Military Service Conscription Register and the Total Population and the Population and Housing Censuses. Psoriasis, asthma (with and without allergic rhinitis) and allergic rhinitis at conscription were studied in 1 226 193 male conscripts in successive cohorts born between 1952 and 1977. RESULTS: The prevalence of psoriasis was about 0.5% and it remained stable over three decades. Conscripts with psoriasis and their siblings were less likely to have eczema. The reduced risk of eczema in conscripts with psoriasis was unchanged over time. A reduced risk of allergic rhinitis was also demonstrated in conscripts with psoriasis and their siblings but only in the most recent birth cohort born between 1970 and 1977. CONCLUSIONS: A strong genetic influence may explain the unchanged prevalence of psoriasis in Swedish conscripts. A genetic predisposition for psoriasis may confer partial protection from eczema and allergic rhinitis. The inverse relationship between allergic rhinitis and psoriasis appeared to be a recent phenomenon.

Reliability of faculty clinical evaluations of non-emergency medicine residents during emergency department rotations.

OBJECTIVES: To assess the reliability of faculty evaluations of non-emergency medicine (non-EM) residents during clinical ED rotations and to determine the effect that the "leniency" of grading by these evaluators had on the residents' final evaluations. METHODS: A prospective, observational study of the evaluation patterns of EM faculty was performed in an academic ED (50,000 visits yearly census). Each resident was evaluated on a daily basis by a board-certified or board-prepared emergency physician. The evaluation form rated 7 characteristics, but only the rating for overall clinical competence was used for data analysis. If an attending evaluated the same resident more than once, only the first evaluation was used to avoid bias from prior exposure. The scoring patterns of the evaluators, both individually and in groups, were analyzed using 1-way analysis of variance. Evaluator leniency was estimated using the mean evaluator score across all residents. Since each resident was evaluated by a different combination of evaluators, evaluator leniency for each resident was estimated from the mean leniency of the evaluators who specifically assessed that resident. RESULTS: During the period of the study, 66 residents rotated through the ED, yielding a total of 401 evaluations. When the scoring patterns of individual evaluators were analyzed, a high degree of variability was found in the mean scores (range 5.23-8.09) and SDs (range 0.45-1.55) across evaluators; p = 0.0001. There was a moderate correlation between the mean overall competence score received by each resident and that resident's evaluators' leniency, r = 0.52; p = 0.0001. CONCLUSIONS: There is significant variability in the scoring patterns of individual evaluators. The evaluators in this study showed large variations in both leniency (as measured by their mean score) and range restriction (as measured by their SD). The differences in evaluator scoring leniency have a moderate correlation with the overall score received by the resident.

Parental use and misuse of antibiotics: are there differences in urban vs. suburban settings?

OBJECTIVE: To compare the frequencies with which suburban and urban parents give their children antibiotics without first consulting a physician. METHODS: This was a prospective, comparative survey of a suburban emergency department (ED) patient population in New Jersey with an annual patient census of 60,000 visits and an urban ED in Connecticut with 58,000 annual visits. A convenience sample of parents with children <18 years of age were enrolled. Patients who were critically ill and/or not oriented were excluded. Subjects provided written answers to a series of closed questions regarding their knowledge and use of antibiotics for their children over the previous 12 months. Categorical data were analyzed by chi-square and Fisher's exact test; continuous data were analyzed by t-tests. All tests were two-tailed with alpha set at 0.05. The primary endpoint, antibiotic "misuse," was defined as parental administration of antibiotics to a child during the previous 12 months without the consultation of a physician. RESULTS: Eight hundred one parents were enrolled; 424 at the suburban site. Parents in the suburban site were significantly different with regard to mean age (39 +/- 7.2 vs. 32 +/- 9.0, p < 0.001), percentage female sex (63% vs. 81%, p < 0.001), percentage white race (78% vs. 34%, p < 0.001), and percentage with private insurance (89% vs. 56%, p < 0.001). A higher percentage of parents at the suburban site had misused antibiotics (12.1% vs. 4.0%; p < 0.001). Using logistic regression, this significant difference in the rate of antibiotic misuse between the two groups remained after adjustment for demographic variables and insurance status of the parents (p < 0.001). Parents at the suburban site were significantly less likely to have been previously discharged with their child from an office or ED setting without antibiotics only to go soon afterwards to another health facility in order to obtain such medications (5% vs. 48%; p < 0.001). CONCLUSIONS: Parents in the suburban setting were more likely to have misused antibiotics for their children. On the other hand, parents in the urban setting were more likely to have been discharged by a physician at one health facility and gone to another physician's office or ED in order to obtain antibiotics for their children.

Oral health behaviour of children and adults in urban and rural areas of Burkina Faso, Africa.

OBJECTIVES: To assess the level of dental knowledge and attitudes among 12 year-old children and 35-44 year-olds in Burkina Faso; to evaluate the pattern of oral health behaviour among these cohorts in relation to location, gender and social characteristics and; to evaluate the relative effect of social-behavioural risk factors on caries experience. DESIGN: Across sectional study including urban and rural subgroups of population. SAMPLE AND METHODS: Multistage cluster sampling of households in urban areas; in rural areas random samples of participants were based on the recent population census. The final study population covered two age groups: 12 years (n = 505) and 35-44 years (n = 493). RESULTS: For both children and adults, levels of oral health knowledge, attitudes and self-care were low; 36% of 12-year-olds and 57% of 35-44-year-olds carried out toothcleaning on a daily basis. Pain and discomfort from teeth were common while dental visits were infrequent. Tooth cleaning was mostly performed by use of chewsticks. Use of toothpaste was rare, particularly fluoridated toothpaste was seldom; 9% of 12-year-olds and 18% of 35-44-year-olds reported use of fluoride toothpaste. Significant differences were found in oral health knowledge, attitudes and practices according to location and gender. At age 12, important factors of high caries experience were location (urban), and consumption of soft drinks and fresh fruits. In 35-44-year-olds, gender (female), high education level, dental visit and occupation (government employee) were the significant factors of high dental caries experience whereas adults using traditional chewing sticks had lower DMFT. CONCLUSIONS: Health authorities should strengthen the implementation of oral disease prevention and health promotion programmes rather than traditional curative care. Community-oriented essential care and affordable fluoride toothpaste should be encouraged.

The future of psychiatry: psychiatrists of the future.

OBJECTIVE: The authors' goal was to examine the changing demographic trends in psychiatry manpower. These changes have important implications for the practice of the profession in the future. METHOD: Each year, the APA Office of Membership, in collaboration with the American Association of Directors of Psychiatric Residency Training, conducts a census of all residents in psychiatry. A survey instrument is sent to the director of residency training in each U.S. program accredited by the Accreditation Council for Graduate Medical Education. Using data from this survey and from the American Medical Association, the authors conducted a study of the changes in the number of psychiatric residents over the last decade, particularly the increases in the number and percentage of women in medicine and psychiatry. RESULTS: They found that the number of psychiatric residents has grown from 4,674 in academic year 1978-1979 to 5,829 in 1987-1988, an increase of 25%. The percentage of women has increased from 32% of all psychiatric residents in 1978-1979 to 41% in 1987-1988. The largest proportions of female physicians and psychiatrists were found in the age groups younger than 35. CONCLUSIONS: Previously documented gender differences that affect practice patterns and career opportunities may very well change as a function of the increasing representation of women in the profession of psychiatry, and these changes need to be taken into account in planning for future patient care and research needs.

Design and descriptive results of the "Growth, Exercise and Nutrition Epidemiological Study In preSchoolers": the GENESIS study.

BACKGROUND: The Growth, Exercise and Nutrition Epidemiological Study in preSchoolers (GENESIS) attempts to evaluate the food and nutrient intakes, as well as growth and development of a representative sample of Greek toddlers and preschool children. In the current work the study design, data collection procedures and some preliminary data of the GENESIS study are presented. METHODS: From April 2003 to July 2004, 1218 males and 1156 females 1 to 5 years old, stratified by parental educational level (Census 1999), were examined from 105 nurseries in five counties. Approximately 300 demographic, lifestyle, physical activity, dietary, anthropometrical and DNA variables have been recorded from the study population (children and parents). RESULTS: Regarding anthropometrical indices, boys were found to be taller than girls at all ages (P < 0.05) and heavier only for the age period from 1 to 3 years old (P < 0.05). No significant differences were found between genders regarding the prevalence of at risk of overweight (16.5% to 18.6% for boys and 18.5 to 20.6 % for girls) and overweight (14.0% to 18.9% for boys and 12.6% to 20.0% for girls). Additionally, boys older than 2 years of age were found to have a higher energy intake compared to girls (P < 0.05). A similar tendency was observed regarding the mean dietary intake of fat, saturated fat, carbohydrates and protein with boys exhibiting a higher intake than girls in most age groups (P < 0.05). CONCLUSION: The prevalence of overweight in the current preschool population is considerably high. Future but more extensive analyses of the GENESIS data will be able to reveal the interactions of the parameters leading to this phenomenon.

Hospitalized cancer patients with severe sepsis: analysis of incidence, mortality, and associated costs of care.

INTRODUCTION: Infection is an important complication in cancer patients, which frequently leads to or prolongs hospitalization, and can also lead to acute organ dysfunction (severe sepsis) and eventually death. While cancer patients are known to be at higher risk for infection and subsequent complications, there is no national estimate of the magnitude of this problem. Our objective was to identify cancer patients with severe sepsis and to project these numbers to national levels. METHODS: Data for all 1999 hospitalizations from six states (Florida, Massachusetts, New Jersey, New York, Virginia, and Washington) were merged with US Census data, Centers for Disease Control vital statistics and National Cancer Institute, Surveillance, Epidemiology, and End Results initiative cancer prevalence data. Malignant neoplasms were identified by International Classification of Disease (ninth revision, clinical modification) (ICD-9-CM) codes (140-208), and infection and acute organ failure were identified from ICD-9-CM codes following Angus and colleagues. Cases were identified as a function of age and were projected to national levels. RESULTS: There were 606,176 cancer hospitalizations identified, with severe sepsis present in 29,795 (4.9%). Projecting national estimates for the US population, cancer patients account for 126,209 severe sepsis cases annually, or 16.4 cases per 1000 people with cancer per year. The inhospital mortality for cancer patients with severe sepsis was 37.8%. Compared with the overall population, cancer patients are much more likely to be hospitalized (relative risk, 2.77; 95% confidence interval, 2.77-2.78) and to be hospitalized with severe sepsis (relative risk, 3.96; 95% confidence interval, 3.94-3.99). Overall, severe sepsis is associated with 8.5% (46,729) of all cancer deaths at a cost of 3.4 billion dollars per year. CONCLUSION: Severe sepsis is a common, deadly, and costly complication in cancer patients.

Socio-economic mobility among patients with schizophrenia or major affective disorder. A 17-year retrospective follow-up.

BACKGROUND: Social mobility among patients with schizophrenia or major affective disorder was compared with that among the general population. METHOD: Mobility was studied retrospectively from 1970 to 1987. Socio-economic status (SES) was defined by occupation as in the population census (upper white-collar, lower white-collar, blue-collar, entrepreneur, farmer, unemployed). All patients aged 30-60 years at discharge (2901 men and 3620 women) in 1987-88 in Finland were included in the study. The SES structure of the general population was used for comparisons. RESULTS: Among patients with schizophrenia there was a constant downward drift, commonly to unemployment. This risk was higher among men than women. In the youngest age group a marked decline from the parents' social status was observed. Among patients with major affective disorder the distribution of SES in 1970 was similar to that of the general population. By 1987, a downward drift was again observed, mainly to unemployment regardless of the initial SES group. The number of patients in occupational categories were usually 30-50% lower than expected. CONCLUSIONS: Schizophrenic patients had a high risk of social drop-out. Among patients with major affective disorder the downward drift was much less.

Multiple sclerosis frequency in Israel's diverse populations.

BACKGROUND: Israel has served for almost half a century as a site for epidemiologic studies of multiple sclerosis (MS). Its small geographic size, well-equipped, accessible, and subsidized health facilities, trained physicians, detailed census data, and a National MS Register, maintained since 1960, offer advantages for accurate determinations of MS frequency in its diverse populations. METHOD: The authors calculated age-specific prevalence of MS in Israeli-born Jewish inhabitants, immigrant Jews from Europe/America and from North Africa/Asia, Israeli-born Christian and Moslem Arabs, Druze, and Bedouins. RESULTS: Prevalence rate of MS per 10(5) population on June 30, 2000, for each of these groups in the order listed was 61.6, 53.7, and 27.9 for the Jewish groups and 35.3, 14.7, 10.9, and 17.3 for the non-Jewish groups. Three tiers in MS prevalence were apparent. The highest rates were in Israeli-born Jews and in Jewish immigrants from Europe/America (significantly higher in the former than the latter). Jewish immigrants from African/Asian countries and Christian Arabs had intermediate MS rates (significantly lower than in the first two groups but not significantly different from each other). Moslem Arabs, Druze, and Bedouins had the lowest rates of MS (significantly lower than in the intermediate group but not significantly different from each other). CONCLUSION: Diverse ethnic groups living in the same geographic area may have significantly different frequencies of MS.

Alcohol use and psychosocial well-being among older adults.

OBJECTIVE: The objective of this study was to examine the relationships of three dimensions of alcohol consumption (frequency of drinking, usual total weekly consumption and quantity per occasion) with social and leisure status, stress and psychological well-being among people ages 65 and older. METHOD: Nurse interviewers completed in-house surveys with 826 older persons (65% women) in one community (67% response rate of the census sample). RESULTS: Overall, relationships tended to be modest or nil. Those relationships between negative functioning and heavier alcohol use that did emerge tended to be associated with higher quantity drinking (i.e., drinks per drinking day) and to some extent volume, but not with frequency of drinking. Of the psychosocial variables, poorer psychological well-being, especially depression, was most highly correlated with heavier drinking. These results were the same controlling for sex, age, education, health and use of depressant medications. CONCLUSIONS: Higher quantity and volume of alcohol use among older people show a modest positive association with poorer psychological well-being, independent of other potentially confounding variables such as sex, age, health or use of depressant medications. Frequency of drinking, however, was not related to psychosocial status.

[Geoprocessing and health promotion: social and environmental inequalities, Brazil].

OBJECTIVE: To characterize social inequalities that represent risk conditions for respiratory tract diseases in children and to describe geoprocessing techniques to identify homogeneous social groups and intervention actions for health promotion. METHODS: The study area comprised the surroundings of a health school center in the city of S o Paulo. Based on 1991 census, housing data on 49 census units in the study area were statistically analyzed and it was obtained the mean of characteristic social and environment variables in these units. Together with local representatives, variables were selected that made up composite indicators related to social insertion and housing quality to allow identifying different conditions of potential exposure to respiratory tract diseases. Using geoprocessing techniques, four homogeneous groups were identified in terms of potential exposure to risk conditions for respiratory diseases. RESULTS: It was obtained a spatial configuration of the groups reflecting different needs in the study area. The methodological instruments used revealed to be important for the development of local actions to be implemented in services that operate in specific geographical areas. CONCLUSIONS: The study contributed to the identification of risk conditions in the health center area, making it possible the joint and inter-sector discussion of conditions related to respiratory tract diseases in children, aiming at promoting equity and improving child health.

Birds of a eucalyptus woodlot in interior São Paulo.

Some 255 birds were recorded between 1982-2001 in and near a 2314-ha "Horto" of old eucalyptus plantations with native understory and a lake, near Rio Claro, in central São Paulo, Brazil. This is close to the 263 recorded in and around a ten-times smaller nearby 230-ha woodlot of semideciduous forest. Different species were 44, for a total of 307 in both areas. One hundred and fifty nonvagrant forest and border species were recorded in 1982-86, a number close to the 152 in the small native woodlot. With dry years and logging of plots in 1985-93, 21 of the 150 species were lost, 42 species decreased in numbers, 49 were stable, 19 increased (15 being border species), and 5 entered (one of dry forest and 4 of borders), so 129 species remained in 1996-2001 compared to 133 in the native woodlot. Open-area birds were 33, versus 50 in better-checked grassy swales in sugar cane near the natural woodlot, for a total of 53. Several species, like some border ones, did not enter the open but isolated and mowed interior lake area, or took years to do so. Water and marsh birds were 46 versus 40 in smaller creeks and ponds near the natural woodlot (total, 55) but many were migrants or infrequent visitors using distant areas, and perhaps should be counted as 0.1-0.9 "local species" rather than "1" species. Use of this more accurate method would reduce waterbird totals by 14 "species" in the Horto and by 11 around the native woodlot. I also recommend longer censusing at the edges in large woodlots or many edge species will be recorded only in small fragments of habitat. Several species increased and others decreased with occasional cat-tail and water-lily cleanups at the lake. A forested corridor between the Horto and natural woodlot is recommended, with old eucalyptus left to provide flowers for hummingbirds.

Associations of neighborhood characteristics with the location and type of food stores.

OBJECTIVES: We investigated associations between local food environment and neighborhood racial/ethnic and socioeconomic composition. METHODS: Poisson regression was used to examine the association of food stores and liquor stores with racial/ethnic composition and income in selected census tracts in North Carolina, Maryland, and New York. RESULTS: Predominantly minority and racially mixed neighborhoods had more than twice as many grocery stores as predominantly White neighborhoods (for predominantly Black tracts, adjusted stores per population ratio [SR]=2.7; 95% confidence interval [CI]=2.2, 3.2; and for mixed tracts, SR=2.2; 95% CI=1.9, 2.7) and half as many supermarkets (for predominantly Black tracts, SR=0.5; 95% CI=0.3, 0.7; and for mixed tracts, SR=0.7; 95% CI=0.5, 1.0, respectively). Low-income neighborhoods had 4 times as many grocery stores as the wealthiest neighborhoods (SR=4.3; 95% CI=3.6, 5.2) and half as many supermarkets (SR=0.5; 95% CI=0.3, 0.8). In general, poorer areas and non-White areas also tended to have fewer fruit and vegetable markets, bakeries, specialty stores, and natural food stores. Liquor stores were more common in poorer than in richer areas (SR=1.3; 95% CI=1.0, 1.6). CONCLUSIONS: Local food environments vary substantially by neighborhood racial/ethnic and socioeconomic composition and may contribute to disparities in health.
