Maternal Depressive Symptoms and Developmental Delay at Age 2: A Diverse Population-Based Longitudinal Study.

OBJECTIVES: Children raised by depressed mothers perform lower on measures of cognitive, emotional, and behavioral skills, compared to children of non-depressed mothers. It is unclear how maternal depressive symptoms (MDS), which persist and accrue over time, impact child development. The purpose of this study was to determine whether cumulative MDS from pre-pregnancy to postpartum influences child development in children by age 2.5. METHODS: Using a longitudinal population-based study design, 2679 racially and ethnically diverse mothers completed the 2014 Los Angeles Mommy and Baby (LAMB) and 2016 Follow-Up surveys. A total MDS score was created based on responses to standardized questions, including the Patient Health Questionnaire-2 (PHQ-2). Data was collected for before pregnancy, during pregnancy, and 4 months postpartum in the 2014 survey, and at 2.5 years postpartum in the 2016 survey. Child development was measured using the CDC's Learn the Signs. Act Early Milestones Checklist. Bivariate and multivariate logistic regressions were conducted. RESULTS: The prevalence of any cumulative MDS was 45.2%. Language, cognitive/adaptive, motor, and social-emotional delays for surveyed toddlers were 7.7%, 4.0%, 1.2%, and 14.2%. After adjusting for covariates, mothers reporting depressive symptoms at all four time points were significantly more likely to report a social-emotional delay in their child (aOR = 4.39, 95% CI - 1.72 to 11.18). CONCLUSIONS FOR PRACTICE: Mothers with cumulative depressive symptoms are at-risk of reporting social-emotional delays by age 2.5. Understanding these effects may help direct resources to target interventions that support mothers with depressive symptoms early-on and promote positive developmental outcomes among their children.

Previous Adverse Infant Outcomes as Predictors of Preconception Care Use: An Analysis of the 2010 and 2012 Los Angeles Mommy and Baby (LAMB) Surveys.

Objectives This study aimed to understand the impact of a previous adverse infant outcome (AIO) on use of preconception care prior to a subsequent pregnancy. Methods Responses from the 2010 and 2012 Los Angeles Mommy and Baby Surveys were analyzed. Weighted multivariate logistic regression was employed to identify significant associations between having had a previous AIO (preterm delivery, low birth weight infant, stillbirth, or major birth defect) and receipt of preconception care prior to the most recent pregnancy. Select patient-level covariates were included: chronic disease, age, education level, race/ethnicity, country of birth, insurance status prior to pregnancy and pregnancy intent. Adjustment for missing responses was performed using multiple chained imputation. Results After controlling for covariates, having had a previous AIO was associated with an increased odds of having utilized preconception care in the most recent pregnancy (OR 1.237, p = 0.040). Per the final regression model, a woman reporting a previous AIO and an intended subsequent pregnancy had a 42.4 % likelihood of having used preconception care. Of these women, only 28.8 % reported doing so because of concern regarding a previous birth complication. Discussion Women reporting a previous AIO were more likely to have used preconception care in a subsequent pregnancy. The prevalence of preconception care utilization remained low overall. Pregnancy intent emerged as a strong secondary predictor; any concerted strategy to improve access to preconception care must include initiatives to help ensure that pregnancies are planned.

Association of Mothers' Perception of Neighborhood Quality and Maternal Resilience with Risk of Preterm Birth.

We examined the associations of mothers' perception of neighborhood quality and maternal resilience with risk of preterm birth and whether maternal resilience moderated the effect of neighborhood quality perception. We analyzed data from 10,758 women with singleton births who participated in 2010-2012 Los Angeles Mommy and Baby surveys. Multilevel logistic regression models assessed the effects of mothers' perception of neighborhood quality and maternal resilience on preterm birth (yes/no), controlling for potential confounders and economic hardship index, a city-level measure of neighborhood quality. Interaction terms were assessed for moderation. Mothers' perception of neighborhood quality and maternal resilience were each uniquely associated with preterm birth, independent of potential confounders (p-values < 0.05). The risk of preterm birth among mothers who perceived their neighborhood as of poor quality was about 30% greater compared to mothers who perceived their neighborhood as of good quality; the risk was 12% greater among mothers with low resilience compared to those with high resilience. Effects of neighborhood quality were not modified by maternal resilience. The findings suggest that mothers' perception of neighborhood quality and resilience are associated with the risk of preterm birth. Further research should explore whether initiatives aimed at improving neighborhood quality and women's self-esteem may improve birth outcomes.

Association Between Life Event Stressors and Low Birth Weight in African American and White Populations: Findings from the 2007 and 2010 Los Angeles Mommy and Baby (LAMB) Surveys.

We examined the association between life events stressors during pregnancy and low birth weight (LBW) among African Americans and Whites, while systematically controlling for potential confounders including individual characteristics and city-level variations and clustering. We analyzed data from 4970 women with singleton births who participated in the 2007 and 2010 Los Angeles Mommy and Baby Surveys. Multilevel logistic regression was used to assess the association between emotional, financial, spousal and traumatic stressors and LBW among African Americans and Whites. Potential confounders included were: the city-level Economic Hardship Index, maternal demographics, pre-pregnancy conditions, insurance, behavioral risk factors and social support. African Americans were significantly more likely to experience any domain of stressors during their pregnancy, compared to Whites (p < 0.001). Only the association between financial stressors and LBW was significantly different between African Americans and Whites (p for interaction = 0.015). Experience of financial stressors during pregnancy was significantly associated with LBW among African Americans (adjusted odds ratio = 1.49; 95 % confidence interval = 1.01-2.22) but not Whites. Differential impact of financial stressors during pregnancy may contribute to racial disparities in LBW between African Americans and Whites. We showed that financial life event stressors, but not other domains of stressors, were more likely to impact LBW among African Americans than Whites. Initiatives aimed at mitigating the negative impacts of financial stress during pregnancy may contribute to reducing disparities in birth outcomes between African Americans and Whites.

The 2007 los angeles mommy and baby study: a multilevel, population-based study of maternal and infant health in los angeles county.

Objectives. In order to comprehensively examine the risks and resources associated with racial-ethnic disparities in adverse obstetric outcomes, the Los Angeles County Department of Public Health and the University of California, Los Angeles, joined efforts to design and implement the 2007 Los Angeles Mommy and Baby (LAMB) study. This paper aims to present the conceptual frameworks underlying the study's development, highlight the successful collaboration between a research institution and local health department, describe the distinguishing characteristics of its methodology, and discuss the study's implications for research, programs, and policies. Methods. The LAMB study utilized a multilevel, multistage cluster design with a mixed-mode methodology for data collection. Two samples were ultimately produced: the multilevel sample (n = 4,518) and the augmented final sample (n = 6,264). Results. The LAMB study allowed us to collect multilevel data on the risks and resources associated with racial-ethnic disparities in adverse obstetric outcomes. Both samples were more likely to be Hispanic, aged 20-34 years, completed at least 12 years of schooling, and spoke English. Conclusions. The LAMB study represents the successful collaboration between an academic institution and local health department and is a theoretically based research database and surveillance system that informs effective programmatic and policy interventions to improve outcomes among LAC's varied demographic groups.

Trends in the use of sexually transmitted disease diagnostic technologies in California, 1996-2003.

OBJECTIVE: To describe trends in STD diagnostic test volume and test technology in California from 1996 to 2003. STUDY: A self-administered survey was mailed annually to licensed clinical laboratories in California that performed STD testing. Data were collected on volume and diagnostic test type for chlamydia, gonorrhea, syphilis, chancroid, HIV, hepatitis B, herpes simplex virus (HSV), and human papilloma virus (HPV). Data were analyzed for trends over time. RESULTS: Response rates ranged from 77% to 99% per survey year. The total number of chlamydia, gonorrhea, and syphilis tests increased from 8.1 to 9.3 million annually. The proportion of chlamydia and gonorrhea tests performed using nucleic acid amplification testing increased from 5% to 66% and from 1% to 59%, respectively. Gonorrhea culture testing decreased from 42% to 10% of all gonorrhea tests. HIV test volume increased from 2.4 to 3.1 million tests. Newer technology tests for HSV and HPV were less common but increased in use. Non-public health laboratories conducted over 90% of all STD testing. CONCLUSIONS: Analyzing trends in diagnostic technologies enhances our understanding of the epidemiology of STDs and monitoring laboratory capacity and practices facilitates implementation of STD control activities.

Predictors of sexually transmitted infection testing among sexually active homeless youth.

We examined the association between sexual risk behaviors and sexually transmitted infection (STI) testing in a sample of homeless youth. Of 261 youth interviewed, 50% had been sexually active in the past 3 months. Gender variation in sexual behaviors and risk were found. Boys were more likely than girls to engage in anal sex (46% vs. 15%), to have 3 or more sexual partners (46% vs. 17%) and to engage in anonymous sex (38% vs. 21%). Girls were less likely to use condoms consistently and more likely to engage in sex with a partner suspected of having an STI (20% vs. 4%). In the past 3 months, the STI testing rates were similar for boys and girls (46%). However, girls were more likely to have positive STI results (46% vs. 9%). In a multivariate logistic regression analysis, the only variable that was an independent predictor of STI testing was having either gotten someone or having become pregnant in the past 3 months. High-risk sexual behaviors did not predict STI testing in our sample. Outreach programs are needed that target sexually active homeless youth for early STI testing and treatment.
