On the measurement of relative and absolute income-related health inequality.

In recent work on international comparisons of income-related inequalities in health, the concentration index has been used as a measure of health inequality. A drawback of this measure is that it is sensitive to whether it is estimated with respect to health or morbidity. An alternative would be to use the generalized concentration index that is based on absolute rather than relative health differences. In this methodological paper, we explore the importance of the choice of health inequality measure by comparing the income-related inequality in health status and morbidity between Sweden and Australia. This involves estimating a concentration index and a generalized concentration index for the eight-scale health profile of the Short Form 36 (SF-36) health survey. We then transform the scores for each scale into a measure of morbidity and show that whether the concentration index is estimated with respect to health or morbidity has an impact on the results. The ranking between the two countries is reversed for two of the eight dimensions of SF-36 and within both countries the ranking across the eight SF-36 scales is also affected. However, this change in ranking does not occur when the generalized concentration index is compared and we conclude with the implications of these results for reporting comparisons of income-related health inequality in different populations.

Social capital, income inequality, and firearm violent crime.

Studies have shown that poverty and income are powerful predictors of homicide and violent crime. We hypothesized that the effect of the growing gap between the rich and poor is mediated through an undermining of social cohesion, or social capital, and that decreased social capital is in turn associated with increased firearm homicide and violent crime. Social capital was measured by the weighted responses to two items from the U.S. General Social Survey: the per capita density of membership in voluntary groups in each state; and the level of social trust, as gauged by the proportion of residents in each state who believed that "most people would take advantage of you if they got the chance". Age-standardized firearm homicide rates for the years 1987-1991 and firearm robbery and assault incidence rates for years 1991-1994 were obtained for each of the 50 U.S. states. Income inequality was strongly correlated with firearm violent crime (firearm homicide, r = 0.76) as well as the measures of social capital: per capita group membership (r = -0.40) and lack of social trust (r = 0.73). In turn, both social trust (firearm homicide, r = 0.83) and group membership (firearm homicide, r = -0.49) were associated with firearm violent crime. These relationships held when controlling for poverty and a proxy variable for access to firearms. The profound effects of income inequality and social capital, when controlling for other factors such as poverty and firearm availability, on firearm violent crime indicate that policies that address these broader, macro-social forces warrant serious consideration.

Supporting the habit: income generation activities of frequent crack users compared with frequent users of other hard drugs.

US Federal sentencing guidelines punish possession of crack cocaine very differently from powder cocaine, based partially upon the assumption that crack users engage more frequently in criminal behavior to pay for their habit. This article analyzed frequent users (those who have used at least 15 of the last 30 days) of crack with subgroups of less frequent hard drug users in terms of various income generation activities reported during the past 30 days. The sample consists of 602 African-Americans who were current (in past 30 days) users or sellers of cocaine powder, crack, and heroin. They were carefully recruited from randomly selected blocks in the Central Harlem area of New York City and interviewed extensively in 1998-1999. Their IGAs were classified into six categories. Compared with not-frequent (less than 15 days) hard drug users, frequent crack and multiple hard drug users were equally likely to be involved in drug distribution activities, but were significantly less likely to have full-time jobs, part-time jobs, aid to families with dependent children or welfare support. They had much higher odds ratios for non-drug related illegal (theft mainly) income generation activities and sex work among women. Often, gender and birth cohort variables had higher odds ratios with specific income generation activities than the frequent use of the primary drug(s). This evidence suggests that very frequent crack users have been stigmatized by, are largely excluded from, and perform very marginal economic roles in the legal economic system (jobs and welfare), the illegal economic system, and even in the hard drug distribution system.

Maternal education and family income as determinants of severe disease following acute diarrhoea in children: a case control study.

In a case-control study among the urban poor of Dhaka, Bangladesh, the association of maternal education and family income with severity of disease due to diarrhoea in children was examined. After adjusting for family income, 7 or more years of school education was associated with 54% reduced risk of severe disease as indicated by the presence of dehydration. Income in the uppermost quartile of this population, independently of maternal education, was associated with 41% reduced risk of severe disease compared to the lowest quartile. In the logistic regression model the effect of maternal education remained high after adjustment for several confounders. Based on the concept that socioeconomic variables operate through a set of proximate variables it is contended that maternal education, independently of economic power, through its impact on disease from acute diarrhoea, favourably influences child survival.

Efficient use of health care resources: the interaction between improved health and reduced health related income loss.

Cost effectiveness is a criterion that is often recommended for prioritizing between different types of health care. A modified use of this criterion can be justified as the outcome of a choice that is made "behind a veil of ignorance." Reduced health will in many cases also gives an income loss that is shared between the patient and society ar large. In the special case where the marginal utilities of health status (measured by QALYs) and income are independent of the health state, an efficient allocation of health resources is characterized by net marginal costs per QALY being equalized across different types of health care. Net marginal costs are equal to gross marginal costs minus the reduction in health related income losses due to treatment. In the general case where marginal utilities depend on the health state this rule must be modified.

Inpatient hospital care for lumbar intervertebral disc disorders in Finland in relation to education, occupational class, income, and employment.

The object of the study was to describe socioeconomic and demographic determinants of inpatient hospital care for lumbar intervertebral disc disorders (LIDD) in Finland. Information from the 1996 Finnish Hospital Discharge Register was linked with the 1995 Population Census. Poisson regression analyses were made with the total and the gainfully employed workforce aged 20-64 y as reference. All 48 public and seven private acute care general hospitals treating LIDD patients in Finland. In the workforce, 4643 patients aged 20-64 y (3692 among the gainfully employed) were admitted to the hospital due to LIDD (ICD-10: M51.1-M51.9) in 1996. About one-half were treated surgically. The duration of unemployment in 1995 was inversely associated with hospitalisation for LIDD in 1996, allowing for age, sex, education and personal income (unemployed for 12 months vs 0 months: rate ratio 0.66; 95% CI 0.57-0.77). Among those employed for 12 months in 1995, the level of education was inversely associated with the hospital admission rate. The rate was also higher in manual occupations as compared with the upper white-collar employees. The associations were clearer among the medically than the surgically treated patients. Hospitalisation for back disorder was, however, less common in the lowest income group as compared with the highest (0.65; 0.57-0.77) allowing for education, occupational class, age and sex. Women were less often admitted to the hospital than men, allowing for the socioeconomic factors (0.83; 0.77-0.90). When indicated by education or occupation, low socioeconomic status was associated with a relatively high rate of inpatient hospital care for LIDD. When indicated by personal income, the situation was the reverse. Unemployment and female gender predicted a relatively low rate of hospitalisation.

[Analysis of the cost-income ratio for open and laparoscopic sigmoid resection].

Based on the example of the sigmoid resection, we did a cost-income analysis evaluating the particular expenses and effects of the new DRG-based medical financing system. We analysed the cost of diagnostic tests, medication and nutrition, surgery, personnel and non medical expenses for 20 open and 27 laparoscopic operated patients. The cost of open surgery was calculated to be 3,288.44 euro per patient while laparoscopic surgery was calculated to cost 4,271.98 euro. Based on an average hospitalisation period of 16 days, the estimated income for the hospital was 5,738.98 euro. Independent of the length of hospitalisation, an income of 6,621.34 euro for the hospital was estimated using the new DRG-based medical financing system. Thus, implementation of the new DRG-based medical financing system makes it possible to give patients the benefit of shorter hospital stays following laparoscopic surgery. The cost for the hospital, however, is only minimally reduced.

A comparison of the educational costs and incomes of physicians and other professionals.

BACKGROUND: Efforts at physician-payment reform in the United States have focused largely on the relative incomes of primary care physicians and specialists, who more often have procedure-based practices. Comparisons of the incomes of physicians and other professional groups have received less attention. METHODS: We used standard financial techniques to determine the return on educational investment over a working lifetime for five groups of professionals: primary care physicians, specialist physicians, dentists, attorneys, and graduates of business schools. RESULTS: In current dollars, the difference in the average future hourly income between a given professional and a high-school graduate of the same age, after educational expenses are subtracted (average hours-adjusted net present value of the educational investment) was greatest for specialist physicians and attorneys; dentists and businesspeople had intermediate values; and primary care physicians had the lowest value. The annual yield on the educational investment over a working life (hours-adjusted internal rate of return) was 15.9 percent for primary care physicians, as compared with 29.0 percent for businesspeople, 25.4 percent for attorneys, 20.9 percent for specialist physicians, and 20.7 percent for dentists. A sensitivity analysis showed that primary care physicians did less well in terms of the return on investment than the other groups even when we varied the assumptions in our model widely and that specialist physicians did less well than attorneys working in law firms and dental specialists. CONCLUSIONS: Students can expect a poorer financial return on their educational investment when they choose a career in primary care medicine than when they choose a procedure-based medical or surgical specialty, business, the law, or dentistry.

What users want in e-commerce design: effects of age, education and income.

Preferences for certain characteristics of an online shopping experience may be related to demographic data. This paper discusses the characteristics of that experience, demographic data and preferences by demographic group. The results of an online survey of 488 individuals in the United States indicate that respondents are generally satisfied with their online shopping experiences, with security, information quality and information quantity ranking first in importance overall. The sensory impact of a site ranked last overall of the seven characteristics measured. Preferences for these characteristics in e-commerce sites were differentiated by age, education and income. The sensory impact of sites became less important as respondents increased in age, income or education. As the income of respondents increased, the importance of the reputation of the vendor rose. Web site designers may incorporate these findings into the design of e-commerce sites in an attempt to increase the shopping satisfaction of their users. Results from the customer relationship management portion of the survey suggest that current push technologies and site personalization are not an effective means of achieving user satisfaction.

Cash income, intrahousehold cooperative conflict, and child health in central Mozambique.

This study presents qualitative data on individual cash income generation and intrahousehold bargaining in a sample of 100 households in central Mozambique. It is now recognized that intrahousehold resource allocation patterns can be critical determinants of children's health in the developing world. Recently developed "bargaining-power" models suggest that individual incomes are often not pooled in households and that decisions are the result of a bargaining process that involves cooperation and conflict between men and women. Women's income, many believe, is more often spent on child welfare. Development projects should target benefits to women for greater impact on child health. Some argue that households consist of separate, gendered spheres of economic responsibility that intersect through a "conjugal contract" that defines the terms of cooperation. The findings here support the "separate-spheres" depiction of the household and reveal women's subordinated position in the external cash economy, which undermines their intrahousehold bargaining power.

Family perceptions of the usual source of care among children with asthma by race/ethnicity, language, and family income.

A usual source of care (USC) can serve as the foundation for good primary health care and is critical for children living with a chronic health condition. This study applies national data to the following objectives: (1) describe family reports of the presence and characteristics of the USC for children with asthma; (2) examine evidence of systematic differences in the USC for these children with asthma by race/ethnicity, English language proficiency in Hispanic respondents, and family income; and (3) conduct multivariate analysis adjusting for possible confounding factors to examine independent effects of race/ethnicity, language, and income. Data from the 1996-2000 Medical Expenditure Panel Survey (MEPS) were analyzed. Overall, 95% of children with asthma had a USC, with Spanish-speaking Hispanics least likely to report a USC (89%). There were significant differences in USC attributes by race/ethnicity, language, and income, with the largest differences by type of provider and accessibility. Hispanics with poor English language proficiency had the greatest accessibility barriers.

The effect of income on selenium intake and status in Utah County, Utah.

Foodstuffs produced and/or purchased locally were analyzed for Se. The effect of income and gender on Se intake and status of Utah County residents was evaluated by measurement of the following indicators: erythrocyte (RBC) and plasma Se concentration, and activity of Se-glutathione peroxidase (Se-GSH-Px) (EC 1.11.1.9) in RBCs, platelets, and plasma. A Random Digit Dialing procedure was employed to stratify subjects according to gender and annual family income (less than +10,000, +10,000-20,000, greater than +20,000) in a 2 x 3 factorial design, seven subjects per cell. The weekly consumption of 44 foods shown to contribute over 90% of the Se intake of U.S. subjects was recorded for each study participant. The estimated minimum daily intake for this sample was 76.0 +/- 4.5 micrograms Se/day (mean +/- SEM). Available grain products are not produced locally, and their Se content is lower than average values reported by the U.S.D.A. Locally produced meat and dairy products had higher than average Se contents. In spite of lower grain Se and higher meat Se concentrations, subjects in this study derived more Se from grain and dairy products, and less from meat products than did subjects in a nationwide sample. The Se status of Utah County residents is similar to several other populations in the United States. There were no significant differences in Se status or intake due to gender or income. The results suggest that consumption of other foods produced in a "high Se" area can maintain Se intake and status in spite of reduced consumption of meat products generally viewed as more reliable sources of dietary Se.

HIV/AIDS, income loss and economic survival in Botswana.

In countries facing severe HIV/AIDS epidemics, the overwhelming majority of those who are infected and affected by HIV are already living in poverty. Further income loss can threaten the ability to meet basic needs such as food, education and access to healthcare. Due to this, understanding the impact of HIV infection and caregiving on household income is essential to improving the health and welfare of HIV-affected individuals and families. This qualitative study examines how HIV infection and HIV caregiving affect household income in a population located within Botswana, a country with high HIV prevalence. We find that extended unpaid leave from work or job loss are common consequences and are associated with failure to meet basic needs in the short and long-term. We make recommendations for policy and programme support, including workplace adaptations and public sector support for meeting health and basic needs of HIV-affected families.

Lack of legal income is strongly associated with an increased risk of AIDS and death in HIV-infected injecting drug users.

The aim of the study was to analyze the impact of soci-economic status in addition to other risk factors in the progression of HIV disease in a cohort of injecting drug users (IDUs) with a mean follow-up of two years. Between 1989 and 1992, 124 HIV-infected IDUs were recruited in a primary care outpatient clinic providing free consultations and free access to therapy. The main outcome measures were death and AIDs-defining events. The proportion of current daily injectors at entry in the study and at the end of follow-up was 67.7% and 57.2%, respectively. The proportion of individuals on maintenance opioid therapy at entry in the study and at the end of follow-up was 0 and 12.1%, respectively. CD4 cell counts below 200 x 10(6)/L at baseline, positive p24 antigenemia at baseline, the lack of legal income and occasional drug use at entry were risk factors for clinical progression and death. When adjusted in a multivariate analysis, the absence of legal income remained associated with death and occurrence of an AIDS-defining event with a relative risk of 5.2 (1.5-18.1) (p = 0.004). Lack of legal income is a strong risk factor for progression of HIV disease in IDUs, that is independent of CD4 cell count and p24 antigenemia.

Patient and clinical site factors associated with rescreening behavior among older multiethnic, low-income women.

PURPOSE: Our goal was to identify factors predictive of mammography rescreening within 18 months of baseline screening in multiethnic, low-income older women. DESIGN AND METHODS: We interviewed a cross-sectional survey of staff of 102 randomly selected clinics that provided screening and diagnostic services. We also surveyed a random sample of 391 older women served by these clinics to retrospectively assess their experiences of the screening process. RESULTS: We found that 59% of the sample returned for a repeat mammogram. Education level and the belief it is important to get an annual mammogram were significant patient-level predictors of rescreening. Offering pap smears and using hands-on demonstrations with breast models were significant clinic-level variables predictive of rescreening. Of note, among the variables that did not prove significant in the final model were those reflecting ethnicity and income. IMPLICATIONS: Individual and health-care-delivery-system factors play important roles in the obtaining of regular mammograms by low-income women. These findings highlight the importance of both factors in improving rescreening rates among older women.

Education, income, occupation, and the 34-year incidence (1965-99) of Type 2 diabetes in the Alameda County Study.

BACKGROUND: Lower socioeconomic position (SEP) is related to higher prevalence of Type 2 diabetes, yet little is known about the relationship of SEP with incident diabetes. METHODS: The association between SEP, measured by self-reported education, income, and occupation, and Type 2 diabetes incidence was examined in a community sample of 6147 diabetes-free adults from Alameda County, CA. Cox proportional hazards models estimated the effect of baseline (1965) and time-dependent (value changes over time) measures of SEP on incident diabetes over a 34-year study period (1965-99). Demographic confounders (age, gender, race, and marital status) and potential components of the causal pathway (physical inactivity, smoking, alcohol consumption, body composition, hypertension, depression, and health care access) were included as fixed or time-dependent covariates. RESULTS: Education, income, and occupation were associated with increased diabetes risk in unadjusted models. In baseline models adjusted for demographics, respondents with <12 years of education had 50% excess risk compared with those with more education [hazard ratio (HR) = 1.5, 95% confidence interval (95% CI) 1.11-2.04], but income and occupation were no longer significantly associated with increased risk. Further adjustment minimized the significance of all associations. Time-dependent effects were consistently elevated for low education and male blue-collar occupation, but non-significant after full adjustment (HR = 1.1, 95% CI 0.79-1.47 and HR = 1.3, 95% CI 0.91-1.89, respectively). CONCLUSIONS: Socioeconomic disadvantage, especially with low educational attainment, is a significant predictor of incident Type 2 diabetes, although associations were largely eliminated after covariate adjustment. Obesity and overweight appear to mediate these associations.

Patterns of long-term change in body composition are associated with diet, activity, income and urban residence among older adults in China.

Studies describing patterns of long-term change in body composition are lacking. Using longitudinal data on 608 healthy, nonobese Chinese (aged 50-70 y) from the 1993 and 1997 China Health and Nutrition Surveys, this article describes the prevalence, sociodemographic and lifestyle correlates of patterns of long-term change in midarm muscle area (MAMA) and body fat (waist circumference). All patterns of change (loss, maintenance [Delta < 1.3 cm(2)], or gain of MAMA with concurrent loss, maintenance [Delta < 2 cm(2)] or gain of body fat), were observed for this sample. After controlling for sex, baseline age, urban residence, height, weight, income, MAMA, waist circumference, smoking status, activity level, mean daily energy and protein intakes (from three 24-h recalls), and change in height, it was determined that subjects who lost both arm muscle and body fat were distinguished from subjects who lost arm muscle but gained body fat by lower income and energy intake at baseline. Although protein intakes at baseline did not differ between the groups that lost arm muscle, protein intakes were significantly higher for subjects who gained both muscle and fat. Patterns of change involving gains in arm muscle were associated with increased protein intake, urban residence, as well as moderate or heavy levels of physical activity at baseline. Variation in protein intake, physical activity, and urban residence also differentiated between the groups that gained fat. Patterns of age-related change in body composition appear associated with modifiable variables, including income, urban residence, activity and protein and energy intake.

Family food insufficiency, but not low family income, is positively associated with dysthymia and suicide symptoms in adolescents.

Food insufficiency has been shown to be associated with poor health, academic and psychosocial outcomes in American children, but the relationship between food insufficiency and depressive disorders in U.S. adolescents has not been studied. Further, there are no national estimates of the prevalence of depressive disorders for U.S. adolescents, nor investigation of associations with sociodemographic characteristics using national data. Therefore, we analyzed data for 15- and 16-y-old adolescents from the Third National Health and Nutrition Examination Survey (NHANES III). Depressive disorders and suicidal symptoms were assessed using the Diagnostic Interview Schedule. Adolescents were classified as "food insufficient" if a family respondent reported that the family sometimes or often did not have enough to eat. The prevalence of depression outcomes is reported by sociodemographic characteristics. Odds ratios for associations with food insufficiency are reported, adjusted for sociodemographic factors. Overall, lifetime prevalence of major depressive disorder was 6.3% and of dysthymia, 5.4%. Almost 5% of 15- to 16-y-old adolescents reported that they had ever attempted suicide and 38.8% reported at least one suicidal symptom. Female adolescents were significantly more likely than males to have had dysthymia, any depressive disorder and all symptoms of suicide. Low income adolescents were less likely to report suicide ideation than high income adolescents, but there were no other differences by family income. Food-insufficient adolescents were significantly more likely to have had dysthymia, thoughts of death, a desire to die and have attempted suicide. There is a strong association between food insufficiency and depressive disorder and suicidal symptoms in U.S. adolescents.
