Effects of out-of-school care on sex initiation among young adolescents in low-income central city neighborhoods.

OBJECTIVE: To examine the association between patterns of out-of-school care over time and the initiation of sex among young adolescents living in low-income urban families. DESIGN: A prospective cohort study (using a 16-month follow-up) examining the predictive value of changes in out-of-school-care arrangements on early sex initiation. SETTING AND PARTICIPANTS: By using a multistage stratified area probability sampling strategy, we selected 494 subjects aged 11 to 13 years living in low-income central city neighborhoods who did not report having had sexual intercourse by time 1. MAIN OUTCOME MEASURE: Adolescent report of having had sexual intercourse by time 2. RESULTS: Bivariate results suggested that being at home with an adult during out-of-school hours was related to less sex initiation than self-care, care at another person's home, and attendance at an organized/supervised activity. Adjusting for demographic attributes, parental monitoring, parental curfews, and family routines, remaining in out-of-home care or self-care was associated with a 2.5 times (95% confidence interval, 1.3-5.1 times) increase in the likelihood of initiating sexual intercourse when compared with being at home with an adult at both assessment times. CONCLUSION: Policies and programs that enable young adolescents to spend their out-of-school hours at home with an adult may help reduce the risk of early sex initiation among youth in low-income urban areas.

A randomized trial assessing the efficacy of peer counseling on exclusive breastfeeding in a predominantly Latina low-income community.

OBJECTIVE: To assess the efficacy of peer counseling to promote exclusive breastfeeding (EBF) among low-income inner-city women in Hartford, Conn. DESIGN: Participants recruited prenatally were randomly assigned to either receive support for EBF from a peer counselor plus conventional breastfeeding support (peer counseling group [PC]) or only conventional breastfeeding support (control group [CG]) and followed through 3 months post partum. SETTING: Low-income predominantly Latina community. PARTICIPANTS: Expectant mothers, less than 32 weeks gestation and considering breastfeeding (N = 162). Intervention Exclusive breastfeeding peer counseling support offering 3 prenatal home visits, daily perinatal visits, 9 postpartum home visits, and telephone counseling as needed. MAIN OUTCOME MEASURES: Exclusive breastfeeding rates at hospital discharge, 1, 2, and 3 months post partum (n = 135). RESULTS: At hospital discharge, 24% in the CG compared with 9% in the PC had not initiated breastfeeding, with 56% and 41%, respectively, nonexclusively breastfeeding. At 3 months, 97% in the CG and 73% in the PC had not exclusively breastfed (relative risk [RR] = 1.33; 95% CI, 1.14-1.56) during the previous 24 hours. The likelihood of nonexclusive breastfeeding throughout the first 3 months was significantly higher for the CG than the PC (99% vs 79%; RR = 1.24; 95% CI, 1.09-1.41). Mothers in the CG were less likely than their PC counterparts to remain amenorrheic at 3 months (33% vs 52%; RR = 0.64; 95% CI, 0.43-0.95). The likelihood of having 1 or more diarrheal episode in infants was cut in half in the PC (18% vs 38%; RR = 2.15; 95% CI, 1.16-3.97). CONCLUSION: Well-structured, intensive breastfeeding support provided by hospital and community-based peer counselors is effective in improving exclusive breastfeeding rates among low-income, inner-city women in the United States.

Cost-effectiveness of evidence-based pharmacotherapy or cognitive behavior therapy compared with community referral for major depression in predominantly low-income minority women.

BACKGROUND: Few clinical trials have evaluated interventions for major depressive disorder in samples of low-income minority women, and little is known about the cost-effectiveness of depression interventions for this population. OBJECTIVE: To evaluate the cost-effectiveness of pharmacotherapy or cognitive behavior therapy (CBT) compared with community referral for major depression in low-income minority women. DESIGN, SETTING, AND PARTICIPANTS: A randomized clinical trial was conducted in 267 women with current major depression. INTERVENTIONS: Participants were randomly assigned to pharmacotherapy (paroxetine hydrochloride or bupropion hydrochloride) (n = 88), CBT (n = 90), or community referral (n = 89). MAIN OUTCOME MEASURES: The main outcomes were intervention and health care costs, depression-free days, and quality-adjusted life years based on Hamilton Depression Rating Scale scores and Medical Outcomes Study 36-Item Short-Form Health Survey summary scores for 12 months. Cost-effectiveness ratios were estimated to compare incremental patient outcomes with incremental costs for pharmacotherapy relative to community referral and for CBT relative to community referral. RESULTS: Compared with the community referral group, the pharmacotherapy group had significantly lower adjusted mean Hamilton Depression Rating Scale scores from the 3rd month through the 10th month (P = .04 to P<.001) of the study, and the CBT group had significantly lower adjusted mean scores from the 5th month through the 10th month (P = .03 to P = .049). There were significantly more depression-free days in the pharmacotherapy group (mean, 39.7; 95% confidence interval, 12.9-66.5) and the CBT group (mean, 25.80; 95% confidence interval, 0.04-51.50) than in the community referral group. The cost per additional depression-free day was USD 24.65 for pharmacotherapy and USD 27.04 for CBT compared with community referral. CONCLUSIONS: Effective treatment for depression in low-income minority women reduces depressive symptoms but increases costs compared with community referral. The pharmacotherapy and CBT interventions were cost-effective relative to community referral for the health care system.

Long-term effects of an early childhood intervention on educational achievement and juvenile arrest: A 15-year follow-up of low-income children in public schools.

CONTEXT: Most studies of the long-term effects of early childhood educational interventions are of demonstration programs rather than large-scale public programs. Previous studies of one of the oldest federally funded preschool programs have reported positive effects on school performance, but effects on educational attainment and crime are unknown. OBJECTIVE: To determine the long-term effectiveness of a federal center-based preschool and school-based intervention program for urban low-income children. DESIGN, SETTING, AND PARTICIPANTS: Fifteen-year follow-up of a nonrandomized, matched-group cohort of 1539 low-income, mostly black children born in 1980 and enrolled in alternative early childhood programs in 25 sites in Chicago, Ill. INTERVENTIONS: The Chicago Child-Parent Center (CPC) Program (n = 989 children) provides comprehensive education, family, and health services and includes half-day preschool at ages 3 to 4 years, half- or full-day kindergarten, and school-age services in linked elementary schools at ages 6 to 9 years. The comparison group (n = 550) consisted of children who participated in alternative early childhood programs (full-day kindergarten): 374 in the preschool comparison group from 5 randomly selected schools plus 2 others that provided full-day kindergarten and additional instructional resources and 176 who attended full-day kindergartens in 6 CPCs without preschool participation. MAIN OUTCOME MEASURES: Rates of high school completion and school dropout by age 20 years, juvenile arrests for violent and nonviolent offenses, and grade retention and special education placement by age 18 years. RESULTS: Relative to the preschool comparison group and adjusted for several covariates, children who participated in the preschool intervention for 1 or 2 years had a higher rate of high school completion (49.7 % vs 38.5%; P =.01); more years of completed education (10.6 vs 10.2; P =.03); and lower rates of juvenile arrest (16.9% vs 25.1%; P =.003), violent arrests (9.0% vs 15.3%; P =.002), and school dropout (46.7% vs 55.0%; P =.047). Both preschool and school-age participation were significantly associated with lower rates of grade retention and special education services. The effects of preschool participation on educational attainment were greater for boys than girls, especially in reducing school dropout rates (P =.03). Relative to less extensive participation, children with extended program participation from preschool through second or third grade also experienced lower rates of grade retention (21.9% vs 32.3%; P =.001) and special education (13.5% vs 20.7%; P =.004). CONCLUSIONS: Participation in an established early childhood intervention for low-income children was associated with better educational and social outcomes up to age 20 years. These findings are among the strongest evidence that established programs administered through public schools can promote children's long-term success.

Strategies for integrating primary health services in middle- and low-income countries at the point of delivery.

BACKGROUND: Strategies to integrate primary health care aim to bring together inputs, organisation, management and delivery of particular service functions to make them more efficient, and accessible to the service user. In some middle and low income countries, services have been fragmented by separate vertical programmes established to ensure delivery of particular technologies. We examined the effectiveness of integration strategies at the point of delivery. OBJECTIVES: To assess the effects of strategies to integrate primary health care services on producing a more coherent product and improving health care delivery and health status. SEARCH STRATEGY: We searched the Cochrane Effective Practice and Organisation of Care Group specialised register (August 2005), MEDLINE (1966 to September 2005), EMBASE (1988 to 2005), Socio Files (1974 to September 2005), Popline (1970 to September 2005), HealthStar (1975 to September 2005), Cinahl (1982 to September 2005); Cab Health (1972 to 1999), International Bibliography of the Social Sciences (1970 to 1999), and reference lists of articles. We also searched the Internet and World Health Organization (WHO) library database, hand searched relevant WHO publications and contacted experts in the field. SELECTION CRITERIA: Randomised trials, controlled before and after studies, and interrupted time series analyses of integration strategies in primary health care services. Health services in high-income countries were excluded. The primary outcomes were indicators of health care delivery, user views on any measure of service coherence, and health status. We also sought information on comparative costs. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data and assessed study quality. MAIN RESULTS: Three cluster randomised trials and two controlled before and after studies were included, with three types of comparison: integration by adding on an additional component to an existing service (family planning); integrated services versus single special services (for sex workers); integrated delivery systems versus a vertical service (for family planning); and packages of enhanced primary child care services (integrated management of childhood illnesses) vs. routine child care. Interventions were complex and in some studies inputs varied substantially between comparison arms. Overall, no consistent pattern emerged. Only one study attempted to assess the user's view of the service provided. AUTHORS' CONCLUSIONS: Few studies of good quality, large and with rigorous study design have been carried out to investigate strategies to promote service integration in low and middle income countries. All describe the service supply side, and none examine or measure aspects of the demand side. Future studies must also assess the client's view, as this will influence uptake of integration strategies and their effectiveness on community health.

Are Kirindy sifaka capital or income breeders? It depends.

The capital and income breeding framework has only recently been used to explain variation in female reproductive strategies in primates. The application of this framework to primates and other mammals with long reproductive cycles has not been consistent. We evaluated data on Verreaux's sifaka (Propithecus verreauxi verreauxi) in the Kirindy Forest of western Madagascar to determine whether they are capital or income breeders. We found that Verreaux's sifaka can be classified as either capital or income breeders, depending on how these concepts are operationalized. These conflicting findings highlight why the capital/income framework is currently problematic and must be standardized if it is to be a useful framework for primatologists.

Consumer-led demand side financing in health and education and its relevance for low and middle income countries.

There is increasing awareness that supply subsidies for health and education services often fail to benefit those that are most vulnerable in a community. This recognition has led to a growing interest in and experimentation with, consumer-led demand side financing systems (CL-DSF). These mechanisms place purchasing power in the hands of consumers to spend on specific services at accredited facilities. International evidence in education and health sectors suggest a limited success of CL-DSF in raising the consumption of key services amongst priority groups. There is also some evidence that vouchers can be used to improve targeting of vulnerable groups. There is very little positive evidence on the effect of CL-DSF on service quality as a consequence of greater competition. Location of services relative to population means that areas with more provider choice, particularly in the private sector, tend to be dominated by higher and middle-income households. Extending CL-DSF in low-income countries requires the development of capacity in administering these financing schemes and also accrediting providers. Schemes could focus primarily on fixed packages of key services aimed at easily identifiable groups. Piloting and robust evaluation is required to fill the evidence gap on the impact of these mechanisms. Extending demand financing to less predictable services, such as hospital coverage for the population, is likely to require the development of a voucher scheme to purchase insurance. This suggests an already developed insurance market and is unlikely to be appropriate in most low-income countries for some time.

Cardiovascular disease risk factor intervention in low-income women: the North Carolina WISEWOMAN project.

OBJECTIVES: The North Carolina WISEWOMAN project was initiated to evaluate the feasibility of expanding an existing cancer screening program to include a cardiovascular disease (CVD) screening and intervention program among low-income women. METHODS: Seventeen North Carolina county health departments were designated as minimum intervention (MI), and 14 as enhanced intervention (EI). The EI included three specially constructed counseling sessions spanning 6 months using a structured assessment and intervention program tailored to lower income women. RESULTS: Of the 2,148 women screened, 40% had elevated total cholesterol (> or = 240 mg/dL), 39% had low high-density lipoprotein cholesterol (HDL-C) levels (< 45 mg/dL), and 63% were hypertensive (systolic blood pressure 140 and/or diastolic blood pressure > or = 90 mm Hg or on hypertensive medication). The majority of women (86%) had at least one of these three risk factors. Seventy-six percent were either overweight or obese. After 6 months of follow-up in the EI health departments, changes in total cholesterol levels, HDL-C levels, diastolic blood pressure, and BMI were observed (-5.8 mg/dL, -0.9 mg/dL, -1.7 mm Hg, and -0.3 kg/m(2), respectively), but were not significantly different from MI health departments. A dietary score that summarized fat and cholesterol intake improved by 2.1 units in the EI group, compared with essentially no change in the MI group. CONCLUSIONS: Expanding existing cancer screening programs to include CVD intervention was feasible and may be an effective means for promoting healthful dietary practices among low-income women.

Correlates of breast cancer screening among low-income, low-education Latinas.

INTRODUCTION: This paper discusses the factors associated with breast cancer screening among low-education, low-income Latinas. BACKGROUND: These data were collected as part of a breast cancer educational intervention study aimed at this population. The objective of the larger study was to evaluate multimedia methods as an appropriate medium for educating this population of Latinas about breast cancer. METHODS: The study was designed as a field experiment with a pre and posttest design. A total of 1,197 individuals participated in the study, and these were all self-identified Latinas above the age of 40 years who fit the screening criteria of low income and education levels. Of these, 583 individuals provided the baseline (pretest) data on mammogram attitudes, knowledge, and intentions analyzed in this paper. RESULTS: Our results indicate that breast cancer screening knowledge and having a regular doctor were significant factors in ever having had a mammogram and having had a recent mammogram in this sample of low-income, low-education Latinas. Age affected the odds of ever having had a mammogram, but not a recent mammogram. CONCLUSION: Attitudes toward mammography, insurance status, and demographic factors such as foreign birth were not significant predictors of mammography screening in this study.

Determinants of zinc intake in low-income black and white pregnant women.

A prospective study was conducted to evaluate and compare the determinants of dietary zinc intake in black and white low-income pregnant women. The study population consisted of 1298 low-income women (70% Black, 30% White) who received prenatal care at University Hospital at the University of Alabama in Birmingham from 1985 to 1989. Various maternal characteristics were evaluated at the first prenatal visit. Two 24 h recalls were obtained at 18 and 30 wk of gestation to calculate the intakes of dietary zinc and other nutrients. Student's t test, chi2, Pearson correlation coefficients, and multiple regression analyses were used to compare and evaluate the determinants of zinc and other nutrient intakes in Black and White subjects. The mean prepregnancy body mass index and the mean intake of zinc, energy, and all the other nutrients except calcium were significantly higher in Black than in White subjects. There was a significant correlation between zinc and energy intake (r = 0.69, p = 0.001). Age, marital status, parity, socioeconomic status, smoking, and alcohol intake were not significant predictors of zinc or other nutrient intakes. After adjusting for energy intake, race was the only significant predictor of dietary zinc intake. Race and energy intake explained 24% of the variation in zinc intake. Results of this study indicate that after adjusting for other covariates, race and energy intakes are the only predictors of zinc intake in low-income pregnant women.

Social class, income, education, area of residence and psychological distress: does social class have an independent effect on psychological distress in Antalya, Turkey?

AIM: The aim of this study is to determine the separate effects of social class, income, education and area of residence on psychological distress. The study also assesses whether the association between prevalence of high score on the 12-item General Health Questionnaire (GHQ 12) and social class is independent of other variables. METHOD: Psychological distress was assessed by means of the GHQ 12. The study covered 1,092 adults aged 15 years or more living in two different quarters of Antalya. Social class status was defined by occupational position, with income, education and area of residence treated as confounders. Chi-square and logistic regression analyses were used to evaluate the data. RESULTS: Large inequalities in psychological distress by all variables were observed. Psychological distress was significantly associated with class status, after adjusting for income, education, area of residence and other potential confounders (age, sex and marital status). Class inequalities in psychological distress were observed between blue-collar workers/unqualified employees and bourgeoisie. CONCLUSIONS: These findings support the view that the recent widening of inequalities among social classes in Turkey pose a substantial threat to health.

Cleavage of incoming Semliki Forest virus capsid protein within the endocytotic pathway: a feature common to both invertebrate and mammalian cells.

During the initial stages of Semliki Forest virus (SFV) infection in mammalian (baby hamster kidney, BHK) cells, the cleavage of SFV capsid protein could be detected. Analysis of subcellular fractions from SFV-infected BHK cells showed that (a) cleavage of the capsid protein occurred within a prelysosomal compartment of the endocytotic pathway, and (b) following release of the nucleocapsid into the cytoplasm, a 17.5 kD capsid protein fragment could be detected in the subcellular fraction which contained ribosomes. We have previously reported the cleavage of incoming SFV capsid protein in mosquito cells, too. Thus, the proteolytic cleavage of incoming SFV capsid protein is a feature which is common to both invertebrate and mammalian cells. These data further support our hypothesis that the cleavage of incoming capsid protein might provide the conformational change which primes the SFV nucleocapsid for uncoating.

Apartment-based breast cancer education program for low income Vietnamese American women.

The purpose of the project was to develop and implement an apartment-based intervention that would improve the knowledge and preventive health habits of hard to reach low income Vietnamese women regarding breast cancer. The targets were Vietnamese women aged 40 and older who resided in apartments in low-income communities in Houston. Twenty apartments were identified and randomly assigned to intervention and control groups. A total of 345 Vietnamese women participated in the project. Follow-up telephone interviews were conducted at five months. Results showed that the intervention group demonstrated significant changes in knowledge and attitudes about breast cancer. Implications of this study include support for culturally appropriate education offered at convenient locations that emphasizes the benefits of early detection of breast cancer for low-income Vietnamese women.

Efforts to locate low-income women for a study on mammography rescreening: implications for public health practice.

Public health practice often requires locating individuals in the community. This article presents information on the methods and amount of time and effort required to locate over 2300 low-income and minority women in Maryland, New York, Ohio, and Texas for a mammography rescreening study. In 1999, we identified 2528 low-income women who had a mammogram in 1997 funded by the National Breast and Cervical Cancer Early Detection Program. Starting 30 months after that mammogram, we made numerous attempts to locate each woman while recording the number of calls, letters, and tracing attempts used and the date she was found. More than 93% of the women were located. On average, it took 73.8 days (range 1-492 days) and 7.2 calls and letters (range 1-48) to reach each woman. Locating women in racial and ethnic minority groups required more time and effort. About 10% of all located women were found only after our subject tracing protocol was implemented. The percentage of located women increased markedly with more months of effort and additional calls and letters. Because women who were more difficult to locate were less likely to have been rescreened, the mammography rescreening percentages at the end of the study were slightly lower than they would have been had we terminated location efforts after 1-3 months. Locating low-income women in the community is difficult, particularly when obtaining a high response rate from all groups is important. Terminating data collection prematurely may decrease minority group representation and introduce bias.

The influence of the perceived quality of community environments on low-income women's efforts to walk more.

There is increasing interest in how the quality of community environments influences health. We present the results of a pilot study designed to encourage overweight and obese low-income women to increase their level of physical activity, and explore the factors that either support or constrain their walking. The findings suggest that even relatively small increases in lifestyle physical activity among overweight or obese low-income women (an increase in 2,000 steps per day) can lead to significant weight loss. The interviews we carried out with study participants suggest there are several ways in which the perceived quality of community environments affects low-income women's efforts to increase their steps. Having friends and family living within walking distance was supportive of participant's efforts, in some cases because their homes represented places to walk to, and in others because in addition, friends and family were walking companions. The perceived lack of safety participants reported as a constraint to walking reflected in some cases the fear of being assaulted or harassed, and in others the fear that passers-by would not stop to help if needed. Our findings point to the importance of including community-level interventions that address residents' safety and security concerns, along with future efforts to increase physical activity and decrease obesity among low-socioeconomic status groups.

Depression and health-related quality of life for low-income African-American women in the U.S.

The health-related quality of life (HRQL) impact of depression for low-income young African-American women has not been quantified. Baseline scores on a generic HRQL measure, the SF-36, from a randomized controlled trial of depression treatments were used as a basis for describing the HRQL of depressed (n = 124) and non-depressed (n = 44) low-income African-American young women. Results were compared to U.S. normative values for well adults and for depressed adults. Relationship between SF-36 scores and demographic variables were examined, and SF-36 scores were compared for those with depression only and those with comorbid anxiety. SF-36 scores were lower for all eight subscales relative to the U.S. norms (p < 0.05) and lower on two subscales relative to a general U.S. depressed sample (p < 0.05). Higher age and higher number of children was associated with poorer scores. Comorbid anxiety was present in 66% of the depressed sample; all SF-36 scores for the sample with comorbid anxiety were significantly lower than scores for subjects with depression alone. Results indicate the substantial HRQL impact of depression among low-income young African-American women with depression.

Tobacco use and low-income African Americans: policy implications.

BACKGROUND: Tobacco use has declined in the United States over the past decade, but smoking among low-income populations remains high in comparison. Although many studies have linked poverty and tobacco use, few studies have examined the prevalence and predictors of tobacco use among low-income African Americans in the South. METHODS: A total sample of 388 residents of a Housing Authority complex in the South were surveyed. This cross-sectional study examined the prevalence and predictors for current tobacco use among sampled participants. RESULTS: Results show that low-income populations in the South have high rates of smoking. Of the sample, about 43% were current tobacco users. Findings indicate that tobacco users were more likely to be older, have been exposed to secondhand smoke, have positive attitudes toward tobacco commercials, and have been arrested in the past. Results found several predictors of tobacco use in the study population including age, secondhand smoke, attitude toward tobacco media, and criminal activity. CONCLUSIONS: Housing Authority apartment complexes may be an important target for tobacco use prevention and treatment interventions. Other policy implications are recommended.

Neighbourhood income and mental health: a multilevel follow-up study of psychiatric hospital admissions among 4.5 million women and men.

This multilevel study followed 4.5 million Swedish women and men from 1 January 1998 until 31 December 1999 in order to examine the association between neighbourhood income (defined as proportions of individuals with low income) and psychiatric hospital admissions. Individuals living in the poorest neighbourhoods exhibited a statistically significantly higher risk of being hospitalised for mental disorder than individuals living in the richest neighbourhoods, after adjustment for individual demographic and socioeconomic characteristics. The neighbourhood variance indicated statistically significant differences in psychiatric hospital admissions between neighbourhoods. Both individuals and neighbourhoods need to be targeted in order to enhance mental health in low-income neighbourhoods.
