Maternal social support and neighborhood income inequality as predictors of low birth weight and preterm birth outcome disparities: analysis of South Carolina Pregnancy Risk Assessment and Monitoring System survey, 2000-2003.

Effects of income inequality on health and other social systems have been a subject of considerable debate, but only a few studies have used multilevel models to evaluate these relationships. The main objectives of the study were to (1) Evaluate the relationships among neighborhood income inequality, social support and birth outcomes (low birth weight, and preterm delivery) and (2) Assess variations in racial disparities in birth outcomes across neighborhood contexts of income distribution and maternal social support. We evaluated these relationships by using South Carolina Pregnancy Risk Assessment and Monitoring System (PRAMS) survey for 2000-2003 geocoded to 2000 US Census data for South Carolina. Multilevel analysis was used to simultaneously evaluate the association between income inequality (measured as Gini), maternal social relationships and birth outcomes (low birth weight and preterm delivery). The results showed residence in neighborhoods with medium levels of income inequality was independently associated with low birth weight (OR: 2.00; 95% CI 1.14-3.26), but not preterm birth; low social support was an independent risk for low birth weight or preterm births. The evidence suggests that non-Hispanic black mothers were at increased risks of low birth weight or preterm birth primarily due to greater exposures of neighborhood deprivations associated with low income and reduced social support and modified by unequal income distribution.

Effects of maternal stress on low birth weight and preterm birth outcomes across neighborhoods of South Carolina, 2000-2003.

OBJECTIVE: Studies evaluating the effect of maternal stress on preterm birth (PTB) or low birth weight (LBW) and variations across neighborhood contexts have been inconclusive. The purpose of the study was to examine the relationships among neighborhood contexts, prenatal stress, and birth outcomes, and to further explore the modifying effects of neighborhood contexts. METHODS: We evaluated this objective by using South Carolina Pregnancy Risk Assessment and Monitoring System (PRAMS), 2000-2003 data linked to the 2000 U.S. census data for 8064 women (N = 8064). Principal component analysis with varimax rotation was used to group stress constructs into four main domains (Financial, Emotional, Traumatic, and Spousal-related). We used multilevel logistic regression analysis to estimate the adjusted odds ratio for different models. RESULTS: Maternal stress was significantly associated with increased risks of low birth weight and preterm deliveries. Neighborhood high poverty and low education (upper quartiles) were independently associated with low birth weight but not preterm deliveries and stress appeared as a partial mediator of contextual effects on birth outcomes. The interaction models showed that the relationship between stress and LBW or PTB was modified by neighborhood contexts with risks being greater for infants born in disadvantaged neighborhoods. CONCLUSIONS: Effects of maternal stress on LBW and PTB outcomes may be different for mothers living in different neighborhood contexts. Therefore, investigations that fail to examine places of residence would most likely not identify mothers at risk of LBW or PTB. Policies to improve birth outcomes need to target both places of residence and specific mediating or moderating factors associated with deprived neighborhoods of residence.

Adherence to recommendations for follow-up to abnormal Pap tests.

OBJECTIVE: To evaluate whether timely adherence rates differ by race among women with abnormal Pap tests participating in a cost-free or reduced-cost program. METHODS: Eligible subjects included women aged 47-64 years who received a referral for follow-up care after an abnormal Pap test from 1999 to 2002 in South Carolina (n=330). Adherence was measured as days to receipt of follow-up care after an abnormal Pap test. Cox proportional hazards modeling was used to estimate risk factors associated with time to adherence within 60 and 365 days by race. RESULTS: African-American and non-Hispanic white women had similar adherence to follow-up. Among white women, those with high-grade lesions were less likely to adhere in a timely manner relative to those with low-grade lesions (hazard ratio 0.6, 95% confidence interval [CI] 0.4-1.0). For African-American women, rural residence (hazard ratio: 0.5, 95% CI 0.2-0.9) and history of abnormal Pap tests (hazard ratio 0.6, 95% CI 0.3-1.0) were associated with decreased adherence, whereas less education (hazard ratio 2.3, 95% CI 1.3-3.9) was associated with increased adherence. CONCLUSION: Adherence rates do not differ by race. However, risk factors for adherence within race are variable. Interventions tailored to the differential needs of racial and ethnic groups may prove effective toward increasing timely adherence rates. LEVEL OF EVIDENCE: II.

Understanding barriers for adherence to follow-up care for abnormal pap tests.

OBJECTIVE: Approximately 4000 women annually will die from preventable and treatable cervical cancer. Failure to adhere to follow-up recommendations after an abnormal Pap test can lead to development of cervical cancer. This paper summarizes the body of literature on adherence to follow-up after an abnormal Pap test in order to facilitate development of interventions to decrease morbidity and mortality due to cervical cancer. METHODS: We conducted a comprehensive search of published literature addressing risk factors for adherence or interventions to improve adherence following an abnormal Pap test as the outcome. We included peer-reviewed original research conducted in the United States from 1990 to 2005. RESULTS: Fourteen analytical and twelve experimental studies that met our criteria were reviewed. Lesion severity and health beliefs were consistently associated with adherence rates. Communication interventions, including telephone reminders, counseling, and educational sessions, increased follow-up compliance across intervention studies. Inconsistent evidence for associations among race, income, and age were found. CONCLUSIONS: Further research is needed to reinforce current studies addressing health beliefs and social support. Interventions that focus on the interplay among psychological, educational, and communication barriers are necessary. These interventions should be adapted and applied across various racial/ethnic and socioeconomic groups to reach all women with a high-risk profile for invasive cervical cancer.

Factors influencing help-seeking from informal networks among African American victims of intimate partner violence.

The purpose of this study was to gain an understanding of the challenges African-American women in abusive relationships face when they consider seeking-help from their informal networks. Data are reported from interviews with 15 African-American women who were self-identified as having survived physical intimate partner violence. A 13-item, semi-structured interview guide was developed in order to elicit information from participants. All of the interviews were audio-recorded, transcribed, and coded for analysis. This analysis revealed emergent themes from these interviews concerning the social factors and perceptions that influence help-seeking behavior. Participants perceived their informal networks as willing to offer instrumental support. However, informal networks were not emotionally supportive. Participants also noted that the African-American community at-large believes victims of violence to be "stupid" for remaining in violent relationships. Additional results are also discussed. Results may be used to help enhance efforts to reduce the rates of intimate partner violence among African-Americans.
