Objective: To assess whether newborns' insurance coverage was associated with differences in the allocation of hospital services.Design: Retrospective analysis of computerized hospital discharge data, comparing resource allocation among newborns according to insurance status, controlling for race/ethnicity, diagnoses, hospital characteristics (ownership, teaching status, nursery level), and disposition.Setting: All California civilian acute-care hospitals.Patients: Population-based sample, excluding out-of-hospital and military hospital births. Resource allocation was studied among all newborns discharged in 1987 with evidence of serious problems (N = 29,751).Main Outcome Measures: Length of stay, total charges, and charges per day.Results: Sick newborns without insurance received fewer inpatient services than comparable privately insured newborns with either indemnity or prepaid coverage. This pattern was observed across all hospital ownership types. Mean stay was 15.7 days for all privately insured newborns (15.6 days for those with indemnity and 15.7 days for those with prepaid coverage), 14.8 days for Medicaid-covered newborns, and 13.2 days for uninsured newborns (P less than .001). Length of stay, total charges, and charges per day were 16%, 28%, and 10% less, respectively, for the uninsured than for all privately insured newborns (P less than .001). Resources for newborns covered by Medicaid were generally greater than for the uninsured and less than for the privately insured. Both uninsured and Medicaid-covered newborns were found to have more severe medical problems than the privately insured.Conclusions: The findings cannot be explained by differences in medical need or by differences in non-medically indicated services; they constitute prima facie evidence of inequities that need to be addressed by policy changes.

Objectives Adverse childhood experiences (ACEs) have been linked with ill-health in adulthood, but ACE literature has focused on family disruption or dysfunction (e.g., child abuse, parental separation), with less attention to economic adversity. We examined whether a mother's economic hardship in childhood (EHC) was associated with women's hardships and health-risk behaviors during/just before pregnancy. Methods We analyzed population-based survey data on 27,102 postpartum California women. EHC included respondents' reports that during childhood they/their families experienced hunger because of inability to afford food or moved because of problems paying rent/mortgage and the frequency of difficulty paying for basic needs. We examined six maternal hardships/behaviors during/just before pregnancy, including four hardships (poverty, food insecurity, homelessness/no regular place to sleep, intimate partner violence) and two behaviors (smoking, binge drinking). Prevalence ratios (PRs) were calculated from sequential logistic regression models estimating associations between EHC (categorized by level of hardship) and each maternal hardship/behavior, first without adjustment, then adjusting for other childhood and current maternal factors, and finally adding family disruption/dysfunction. Results Before adjustment for family disruption/dysfunction, the highest and intermediate EHC levels were associated with each maternal hardship/behavior; after full adjustment, those associations persisted except with smoking. Higher EHC levels generally appeared associated with larger PRs, although confidence intervals overlapped. Conclusions for Policy/Practice These findings link childhood economic hardship with women's hardships, binge drinking, and possibly smoking around the time of pregnancy. Without establishing causality, they support previous research indicating that childhood economic adversity should be considered an ACE.

Objectives: To investigate the contribution of school neighborhood socioeconomic advantage to the association between school-district physical education policy compliance in California public schools and Latino students' physical fitness., Methods: Cross-sectional Fitnessgram data for public-school students were linked with school- and district-level information, district-level physical education policy compliance from 2004-2005 and 2005-2006, and 2000 United States Census data. Multilevel logistic regression models examined whether income and education levels in school neighborhoods moderated the effects of district-level physical education policy compliance on Latino fifth-graders' fitness levels., Results: Physical education compliance data were available for 48 California school districts, which included 64,073 Latino fifth-graders. Fewer than half (23, or 46%) of these districts were found to be in compliance, and only 16% of Latino fifth-graders attended schools in compliant districts. Overall, there was a positive association between district compliance with physical education policy and fitness (OR, 95%CI: 1.38, 1.07, 1.78) adjusted for covariates. There was no significant interaction between school neighborhood socioeconomic advantage and physical education policy compliance (p>.05): there was a positive pattern in the association between school district compliance with physical education policy and student fitness levels across levels of socioeconomic advantage, though the association was not always significant., Conclusions: Across neighborhoods with varying levels of socioeconomic advantage, increasing physical education policy compliance in elementary schools may be an effective strategy for improving fitness among Latino children.

Objectives To investigate Latina-White differences in birth outcomes in California from 2003 to 2010, looking for evidence of the often-cited "Latina paradox" and assessing the possible role of socioeconomic factors in observed differences. MethodsUsing statewide-representative data from the California Maternal and Infant Health Assessment, an annual population-based postpartum survey, we compared rates of preterm birth (PTB) and low birth weight (LBW) in five groups: U.S.-born non-Latina Whites ("Whites"), U.S.-born Mexican-Americans, U.S.-born non-Mexican Latinas, Mexican immigrants, and non-Mexican Latina immigrants. Logistic regression models examined the relative likelihood of PTB and LBW for women in each Latina subgroup compared with Whites, before and after adjustment for socioeconomic and other covariates. Results In unadjusted analyses, women in each Latina subgroup appeared more likely than White women to have PTB and LBW, although the increased likelihood of LBW among Mexican immigrants was statistically non-significant. After adjustment for less favorable socioeconomic characteristics among Latinas compared with Whites, observed differences in the estimated likelihoods of PTB or LBW for Latina subgroups relative to Whites were attenuated and (with the exception of PTB among U.S.-born Mexican Americans) no longer statistically significant. Conclusions We found no evidence of a "Latina paradox" in birth outcomes, which some have cited as evidence that social disadvantage is not always health-damaging. As observed in several previous studies, our findings were non-paradoxical: consistent with their socioeconomic disadvantage, Latinas had worse birth outcomes than non-Latina White women. Policy-makers should not rely on a "Latina paradox" to ensure good birth outcomes among socioeconomically disadvantaged Latina women.

Importance: To our knowledge, few published studies have examined the influence of competitive food and beverage (CF&B) policies on student weight outcomes; none have investigated disparities in the influence of CF&B policies on children's body weight by school neighborhood socioeconomic resources., Objective: To investigate whether the association between CF&B policies and population-level trends in childhood overweight/obesity differed by school neighborhood income and education levels., Design, Setting, and Participants: This cross-sectional study, from July 2013 to October 2014, compared overweight/obesity prevalence trends before (2001-2005) and after (2006-2010) implementation of CF&B policies in public elementary schools in California. The study included 2 700 880 fifth-grade students in 5362 public schools from 2001 to 2010., Exposures: California CF&B policies (effective July 1, 2004, and July 1, 2007) and school neighborhood income and education levels., Main Outcomes and Measures: Overweight/obesity defined as a body mass index at or greater than the 85th percentile for age and sex., Results: Overall rates of overweight/obesity ranged from 43.5% in 2001 to 45.8% in 2010. Compared with the period before the introduction of CF&B policies, overweight/obesity trends changed in a favorable direction after the policies took effect (2005-2010); these changes occurred for all children across all school neighborhood socioeconomic levels. In the postpolicy period, these trends differed by school neighborhood socioeconomic advantage. From 2005-2010, trends in overweight/obesity prevalence leveled off among students at schools in socioeconomically disadvantaged neighborhoods but declined in socioeconomically advantaged neighborhoods. Students in the lowest-income neighborhoods experienced zero or near zero change in the odds of overweight/obesity over time: the annual percentage change in overweight/obesity odds was 0.1% for females (95% CI, -0.7 to 0.9) and -0.3% for males (95% CI, -1.1 to 0.5). In contrast, in the highest-income neighborhoods, the annual percentage decline in the odds of overweight was 1.2% for females (95% CI, 0.4 to 1.9) and 1.0% for males (95% CI, 0.3 to 1.8). Findings were similar for school neighborhood education., Conclusions and Relevance: Our study found population-level improvements in the prevalence of childhood overweight/obesity that coincided with the period following implementation of statewide CF&B policies (2005-2010). However, these improvements were greatest at schools in the most advantaged neighborhoods. This suggests that CF&B policies may help prevent child obesity; however, the degree of their effectiveness is likely to depend on socioeconomic and other contextual factors in school neighborhoods. To reduce disparities and prevent obesity, school policies and environmental interventions must address relevant contextual factors in school neighborhoods.

Objectives: We investigated the role of socioeconomic factors in Black-White disparities in preterm birth (PTB)., Methods: We used the population-based California Maternal and Infant Health Assessment survey and birth certificate data on 10 400 US-born Black and White California residents who gave birth during 2003 to 2010 to examine rates and relative likelihoods of PTB among Black versus White women, with adjustment for multiple socioeconomic factors and covariables., Results: Greater socioeconomic advantage was generally associated with lower PTB rates among White but not Black women. There were no significant Black-White disparities within the most socioeconomically disadvantaged subgroups; Black-White disparities were seen only within more advantaged subgroups., Conclusions: Socioeconomic factors play an important but complex role in PTB disparities. The absence of Black-White disparities in PTB within certain socioeconomic subgroups, alongside substantial disparities within others, suggests that social factors moderate the disparity. Further research should explore social factors suggested by the literature-including life course socioeconomic experiences and racism-related stress, and the biological pathways through which they operate-as potential contributors to PTB among Black and White women with different levels of social advantage.

Background: Physical education policies have received increased attention as a means for improving physical activity levels, enhancing physical fitness, and contributing to childhood obesity prevention. Although compliance at the school and district levels is likely to be critical for the success of physical education policies, few published studies have focused on this issue., Purpose: This study investigated whether school district-level compliance with California physical education policies was associated with physical fitness among 5th-grade public-school students in California., Methods: Cross-sectional data from FITNESSGRAM(®) 2004-2006, district-level compliance with state physical education requirements for 2004-2006, school- and district-level information, and 2000 U.S. Census data were combined to examine the association between district-level compliance with physical education policies and children's fitness levels. The analysis was completed in 2010., Results: Of the 55 districts with compliance data, 28 (50%) were in compliance with state physical education mandates; these districts represented 21% (216) of schools and 18% (n=16,571) of students in the overall study sample. Controlling for other student-, school-, and district-level characteristics, students in policy-compliant districts were more likely than students in noncompliant districts to meet or exceed physical fitness standards (AOR=1.29, 95% CI=1.03, 1.61)., Conclusions: Policy mandates for physical education in schools may contribute to improvements in children's fitness levels, but their success is likely to depend on mechanisms to ensure compliance., (Copyright © 2012 American Journal of Preventive Medicine.

To describe income levels and the prevalence of major hardships among women during or just before pregnancy. We separately analyzed 2002-2006 population-based postpartum survey data from California's Maternal and Infant Health Assessment (n = 18,332) and 19 states participating in CDC's Pregnancy Risk Assessment Monitoring System (n = 143,452) to examine income and several hardships (divorce/separation, domestic violence, homelessness, financial difficulties, spouse/partner's or respondent's involuntary job loss or incarceration, and, in California only, food insecurity and no social support) during/just before pregnancy. In both samples, over 30% of women were poor (income 400% FPL experienced one or more hardships. These findings paint a disturbing picture of experiences around the time of pregnancy in the United States for many women giving birth and their children, particularly because 60% had previous births. The high prevalence of low income and of serious hardships during pregnancy is of concern, given previous research documenting the adverse health consequences of these experiences and recognition of pregnancy as a critical period for health throughout the life course. Low income and major hardships around the time of pregnancy should be addressed as mainstream U.S. maternal-infant health and social policy issues.

Objectives: This study examined the income distribution of childbearing women in California and sought to identify income groups at increased risk of untimely prenatal care., Methods: A 1994/95 cross-sectional statewide survey of 10,132 postpartum women was used., Results: Sixty-five percent of all childbearing women had low income (0%-200% of the federal poverty level), and 46% were poor (0%-100% of the federal poverty level). Thirty-five percent of women with private prenatal coverage had low income. Most low-income women with Medi-Cal (California's Medicaid) or private coverage received their prenatal care at private-sector sites. Compared with women with incomes over 400% of the poverty level, both poor and near-poor women were at significantly elevated risk of untimely care after adjustment for insurance, education, age, parity, marital status, and ethnicity (adjusted odds ratios = 5.32 and 3.09, respectively)., Conclusions: This study's results indicate that low-income women are the mainstream maternity population, not a "special needs" subgroup; even among privately insured childbearing women, a substantial proportion have low income. Efforts to increase timely prenatal care initiation cannot focus solely on women with Medicaid, the uninsured, women in absolute poverty, or those who receive care at public-sector sites.

Objectives: This study assessed the validity of health insurance information on California birth certificates., Methods: Insurance information from birth certificates and linked face-to-face interviews was compared for 7428 postpartum women in California., Results: There was excellent agreement between insurance information in birth certificate and interview data, especially when capitated plans were grouped with all other private coverage. Analyses using both data sources produced similar estimates of the likelihood of untimely prenatal care according to type of insurance coverage., Conclusions: Birth certificate data including insurance information appear to be an appropriate resource for examining both the extent of coverage for maternity care and associations between prenatal care use and insurance status.

Objectives: The purpose of this study was to determine whether women's sociodemographic characteristics are independently associated with cesarean delivery., Methods: A retrospective review was conducted of hospital discharge data for singleton first births in California in 1991., Results: After insurance and personal, community, medical, and hospital characteristics had been controlled, Blacks were 24% more likely to undergo cesarean delivery than Whites; only among low-birthweight and county hospital births were Blacks not at a significantly elevated risk. Among women who resided in substantially non-English-speaking communities, who delivered high-birthweight babies, or who gave birth at for-profit hospitals, cesarean delivery appeared to be more likely among non-Whites and was over 40% more likely among Blacks than among Whites., Conclusions: The findings cannot establish causation, but the significant racial/ethnic disparities in delivery mode, despite adjustment for social, economic, medical, and hospital factors, suggest inappropriate influences on clinical decision making that would not be addressed by changes in reimbursement. If practice variations among providers are involved, de facto racial differences in access to optimal care may be indicated. The role of provider and patient attitudes and expectations in the observed racial/ethnic differentials should also be explored.

Background: We studied differences in the incidence of appendiceal perforation in patients with acute appendicitis according to their insurance coverage., Methods: In a retrospective analysis of hospital-discharge data, we examined the likelihood of ruptured appendix among adults 18 to 64 years old who were hospitalized for acute appendicitis in California from 1984 to 1989., Results: After controlling for age, sex, psychiatric diagnoses, substance abuse, diabetes, poverty, race or ethnic group, and hospital characteristics, we found that ruptured appendix was more likely among both Medicaid-covered and uninsured patients with appendicitis than among patients with private capitated coverage (odds ratios, 1.49 [95 percent confidence interval, 1.41 to 1.59] and 1.46 [95 percent confidence interval, 1.39 to 1.54], respectively). After adjustment for the above factors, the risk of appendiceal rupture associated with a lack of private insurance was elevated at both county and other hospitals, but admission to a county hospital was an independent risk factor. In all income groups, appendiceal rupture was more likely with fee-for-service than capitated private coverage (overall odds ratio, 1.20 [95 percent confidence interval, 1.15 to 1.25])., Conclusions: Among patients with appendicitis an increased risk of ruptured appendix may be due to insurance-related delays in obtaining medical care. Both organizational and financial features of Medicaid and various types or levels of private third-party coverage may be involved. The significant association between ruptured appendix and insurance coverage after adjustment for socio-economic differences suggests barriers to receiving medically necessary acute care that should be considered in current deliberations on health policy.

In this study of hospital discharge data on births to residents of an eight-county region of California, we found an increasing lack of health insurance that was associated with an elevated and increasing risk of adverse outcomes in newborns. Between 1982 and 1986, the percentage of newborns without health insurance increased overall by 45 percent (from 5.5 to 8.0 percent; P less than 0.001); the increases were larger among Asians (by 54 percent [from 7.8 to 12.0 percent]; P less than 0.001) and Latinos (by 140 percent [from 8.2 to 19.7 percent]; P less than 0.001). By 1986, the odds ratio for an adverse hospital outcome (defined as a prolonged hospital stay, transfer of the newborn to another institution, or death) was 1.31 (95 percent confidence interval, 1.17 to 1.46) in uninsured as compared with privately insured newborns, with control for race or ethnic group. There was a significant increase in risk over time (P less than 0.03); the comparable odds ratios in 1982 and 1984 were 1.11 (95 percent confidence interval, 0.93 to 1.33) and 1.19 (1.05 to 1.35), respectively. In 1986 the risks were especially elevated for uninsured as compared with privately insured blacks and Latinos (odds ratios, 2.24 [95 percent confidence interval, 1.60 to 3.13] and 1.56 [1.26 to 1.94], respectively); the increases in risk over time were the most marked in these groups. We believe that the elevated and increasing risks for uninsured newborns are explained at least in part by inadequate and diminishing access to care and that this burden is borne disproportionately by blacks and Latinos.
